Patent Description:
In general, a flexible printed circuit board (FPCB) is a flexible board in which a circuit pattern is printed on a flexible insulating board. The FPCB is bendable, and thus, the FPCB enables three-dimensional wiring and efficient space utilization, thereby facilitating miniaturization and weight reduction. Therefore, flexible printed circuit boards are widely used in electronic products mounted to thin and slim parts, such as printers, cameras, and various mobile products.

In order to protect the printed circuit pattern on the flexible printed circuit board, a coverlay film such as a polyimide film is pre-bonded to the surface of a flexible copper clad laminate (FCCL) by a pre-bonding apparatus, and then hot-pressed by a hot-press apparatus. At this time, the pre-bonding process time by the pre-bonding apparatus is about <NUM> to <NUM> seconds, and the hot-pressing process time by the hot-press apparatus is about <NUM> to <NUM> seconds, so there is a difference in the tack time between the two processes. Therefore, when the coverlay is pre-bonded to the printed circuit board by a roll-to-roll method and then bonded thereto, the printed circuit board to which the coverlay is pre-bonded by the pre-bonding apparatus cannot be transferred to the hot-press apparatus due to the difference in the tack time from the hot-pressing process, thereby being stalled, which causes the printed circuit board to sag, resulting in a defect. For this reason, in the prior art, it was impossible to continuously and automatically supply the printed circuit board pre-bonded in the pre-bonding apparatus to the hot-press apparatus. Instead, the printed circuit board pre-bonded in the pre-bonding apparatus was stored separately in a roll form, and the roll was moved to the hot-press apparatus and then unwound to supply the printed circuit board to the hot-press apparatus to perform a hot-pressing process, so the productivity was lowered.

<CIT> provides a first uncoiler for continuously unwinding and supplying a dynamic laminated plate mounted in a roll form in a temporary welding apparatus for welding a dynamic laminated sheet and a coverlay film having a plurality of holes formed at regular intervals along both sides of a longitudinal edge. <CIT> provides a coverlay film attaching apparatus attaching a coverlay film protecting such a board pattern.

An aspect of the present invention is to provide a composite board manufacturing system capable of manufacturing a composite board by automating a pre-bonding process and a hot-pressing process, which are dualized, into a continuous process, and a method thereof.

A composite board manufacturing system according to the present invention is able to manufacture a composite board in a coverlay-printed circuit board structure by unifying a pre-bonding process and a hot-pressing process, which are dualized, through an automatic and continuous roll-to-roll method.

According to an example, one or more first guide roller parts <NUM> are disposed between the coverlay film supply roller part <NUM> and the first splicing part <NUM>, as shown in <FIG>, and guide the coverlay film <NUM> supplied from the coverlay film supply roller part <NUM> to the first splicing part <NUM>.

The release substrate collecting roller part <NUM> is a roller for winding and collecting the release substrate <NUM> separated from the coverlay film <NUM> by a delamination plate part <NUM> of the separation unit <NUM>. As shown in <FIG>, The release substrate collecting roller part <NUM> is positioned below the coverlay film supply roller part <NUM> of the cover film supply unit <NUM>, but is not limited thereto.

The cutting unit <NUM> may cut only the coverlay <NUM> of the coverlay film <NUM> supplied from the coverlay film supply unit <NUM> in a direction (e.g., the Y-axis direction) intersecting the loading direction (the X-axis direction) of the coverlay film and supply the coverlay <NUM> having a predetermined length to the pre-bonding apparatus <NUM> (i.e., the separation unit <NUM>). As shown in <FIG>, the cutting unit <NUM> includes a pair of plate support parts <NUM>, 121a, and 121b, an upper plate part <NUM>, a lower plate part <NUM>, and an upper plate transfer part <NUM>.

The delamination plate part <NUM> is disposed adjacent to the cutting unit <NUM> to separate the coverlay <NUM> and the release substrate <NUM> from the coverlay film <NUM> when the coverlay film <NUM> is supplied from the cutting unit <NUM>. The delamination plate part <NUM> may have a bent part formed at a predetermined angle or more in the moving direction (collecting direction) of the release substrate <NUM> of the coverlay film <NUM> so as to separate the coverlay <NUM> attached to one side of the release substrate <NUM> from the release substrate <NUM> of the coverlay film <NUM> and supply the same to the coverlay seating unit <NUM> of the pre-bonding apparatus <NUM>. At this time, the release substrate <NUM> may be easily separated from the coverlay <NUM> by the force wound on the release substrate collecting roller part <NUM> of the coverlay film supply unit <NUM>. Meanwhile, the coverlay <NUM> separated from the release substrate <NUM> by the delamination plate part <NUM> is supplied to the coverlay seating unit <NUM> of the pre-bonding apparatus <NUM> and seated thereon.

As shown in <FIG>, the release substrate guide roller part <NUM> is a roller that is disposed below the delamination plate part <NUM> to be spaced apart therefrom and guides the release substrate <NUM> to be transferred from the coverlay film <NUM> supplied to the delamination plate part <NUM> to the release substrate collecting roller part <NUM>.

Specifically, the printed circuit board supply roller part <NUM> is a roller that continuously unwinds the printed circuit board <NUM> and supplies the printed circuit board <NUM> to an aligning table unit <NUM> of the pre-bonding apparatus <NUM> to intersect the transfer direction of the coverlay <NUM> transferred to the aligning table unit <NUM> by a pickup transfer unit <NUM>.

The inserted-paper collecting roller part <NUM> is a rewinder roller that collects an inserted paper (not shown) interposed between the printed circuit boards <NUM> wound around the printed circuit board supply roller part <NUM>. According to an example, the inserted-paper collecting roller part <NUM> may be disposed at a position corresponding to the printed circuit board supply roller part <NUM> so as to be spaced apart therefrom. For example, as shown in <FIG>, it may be disposed below the printed circuit board supply roller part <NUM> to be spaced apart from the printed circuit board supply roller part <NUM>. The inserted paper is separated from the printed circuit board <NUM> supplied from the printed circuit board supply roller part <NUM> and wound around the inserted-paper collecting roller part <NUM> by the winding force of the inserted-paper collecting roller part <NUM>, thereby being collected.

The second guide roller part <NUM> is a roller that guides the inserted paper separated from the printed circuit board <NUM> to the inserted-paper collecting roller part <NUM>, while guiding the printed circuit board <NUM> supplied from the printed circuit board supply roller part <NUM> to the pre-bonding apparatus <NUM>. The second guide roller part <NUM> may be disposed between the printed circuit board supply roller part <NUM> and the pre-bonding apparatus <NUM>.

According to an example, a plurality of second guide roller parts <NUM> is disposed between the printed circuit board supply roller part <NUM> and the second splicing part <NUM> to separate the printed circuit board <NUM>, supplied from the printed circuit board supply roller part <NUM>, from the inserted paper and guide the same to the second splicing part <NUM>, and guides the separated inserted paper to the inserted-paper collecting roller part <NUM>.

The second tension adjustment roller part <NUM> is a guide roller capable of changing the vertical position thereof. Specifically, the second tension adjustment roller part <NUM> guides the printed circuit board <NUM> supplied from the printed circuit board supply roller part <NUM> to the pre-bonding apparatus <NUM> and changes in the vertical position of the roller according to the tension of the printed circuit board detected by a load cell. Accordingly, the tension of the printed circuit board <NUM> supplied from the printed circuit board supply roller part <NUM> may be constantly maintained. As described above, the second tension adjustment roller part <NUM> may guide the printed circuit board <NUM> supplied from the printed circuit board supply roller part <NUM> to the pre-bonding apparatus <NUM> at a constant speed.

The second splicing part <NUM> cuts the printed circuit board <NUM> supplied from the printed circuit board supply roller part <NUM> or splices the end of a new printed circuit board <NUM> to the end of an existing printed circuit board <NUM> when replacing the printed circuit board supply roller part <NUM>. The second splicing part <NUM> is disposed adjacent to the printed circuit board supply roller part <NUM> that supplies the printed circuit board <NUM> to the same.

According to an example, although not specifically shown, the second splicing part <NUM> includes: a second plate member; a 2A-clamp member disposed on the second plate member in a direction (e.g., the Y-axis direction) intersecting the loading direction (e.g., the X-axis direction) of the printed circuit board <NUM>; and a 2B-clamp member disposed on the second plate member to be spaced apart from the 2A-clamp member while facing the same. In this case, although not shown, the 2A- and 2B-clamp members may be opened and closed according to the hydraulic pressure applied to the hydraulic cylinder by a pressure control valve, but is not limited thereto.

The second cleaning roller part <NUM> is disposed between the printed circuit board supply roller part <NUM> and the pre-bonding apparatus <NUM>, for example, between the second tension adjustment roller part <NUM> and the aligning table part <NUM> of the pre-bonding apparatus <NUM>, to remove foreign substances from the surface of the printed circuit board <NUM> supplied from the printed circuit board supply roller part <NUM>. The second cleaning roller part <NUM> may include a plurality of adhesive roller members in which adhesive material is applied to the roller surface so as to remove foreign substances by contact. The vertical position (height) of the second cleaning roller part <NUM> may be adjusted according to the hydraulic pressure applied to the hydraulic cylinder by a pressure control valve, but is not limited thereto.

In addition, the second ionizer <NUM> is disposed below the aforementioned second guide roller part <NUM> or second cleaning roller part <NUM> to be spaced apart therefrom to prevent the generation of static electricity in the printed circuit board <NUM>.

As shown in <FIG> and <FIG>, the pre-bonding apparatus <NUM> pre-bonds the coverlay <NUM> having a predetermined length automatically and continuously supplied from the coverlay supply apparatus <NUM> onto the printed circuit board <NUM> automatically and continuously supplied from the printed circuit board supply apparatus <NUM>, thereby discharging a first composite board <NUM>. Here, the first composite board <NUM> includes a printed circuit board <NUM> and a coverlay <NUM> pre-bonded onto the printed circuit board <NUM>.

According to an example, as shown in <FIG>, the pre-bonding apparatus <NUM> may include a coverlay seating unit <NUM>, a pickup transfer unit <NUM>, an aligning table unit <NUM>, and a pre-bonding unit <NUM>, and may further include a first vision unit <NUM> and/or a second vision unit (not shown) as necessary.

The coverlay seating unit <NUM> is a part on which the coverlay <NUM> continuously supplied from the coverlay supply apparatus <NUM> is seated and waiting, and, as shown in <FIG>, includes a seating table part <NUM>, a pair of rail parts 312a and 312b, a transfer body part <NUM>, a coverlay clamp part <NUM>, and a transfer body driving part <NUM>.

The seating table part <NUM> is disposed adjacent to the separation unit <NUM> of the coverlay supply apparatus <NUM> to suction-hold and release the coverlay <NUM> continuously supplied from the coverlay supply apparatus <NUM>. That is, the seating table part <NUM> may suction-hold and release the coverlay <NUM> with a predetermined size, separated from the release substrate <NUM> and supplied from the separation unit <NUM> of the coverlay supply apparatus <NUM>, by a vacuum (negative pressure).

According to an example, the seating table part <NUM> includes: a first plate member <NUM>; a plurality of first vacuum holes <NUM> formed in the first plate member <NUM>; and a first vacuum generating member (not shown) connected to the first vacuum holes <NUM> through a vacuum line (not shown) to generate a vacuum.

In the seating table part <NUM>, a fluid may or may not flow into the plurality of first vacuum holes <NUM> according to the first vacuum generating member (e.g., a vacuum ejector) applying and releasing vacuum pressure (negative pressure) through the vacuum line, so that the coverlay <NUM> may be attached onto or detached from the first plate member <NUM>. Accordingly, the coverlay <NUM> supplied from the separation unit <NUM> is seated on the first plate member <NUM> of the seating table part <NUM> and waits before being transferred to the aligning table unit <NUM> by the pickup transfer unit <NUM>.

In addition, as shown in <FIG>, the seating table part <NUM> is partitioned into a plurality of vacuum regions. As described above, since the vacuum regions of the seating table part <NUM> are individually separated, the vacuum suction sections may be configured depending on the size of the coverlay, thereby securing the suction stability of the coverlay.

As shown in <FIG>, a pair of rail parts 312a and 312b is respectively installed on both sides of the aforementioned seating table part <NUM> in the longitudinal direction (the x-axis direction) of the seating table part <NUM>, and the transfer body part <NUM> reciprocates above the seating table part <NUM> along the pair of rail parts 312a and 312b. At this time, the transfer body part <NUM> is driven by the transfer body driving part <NUM> (e.g., a server motor).

As shown in <FIG> and <FIG>, the coverlay clamp part <NUM> is disposed on the transfer body part <NUM> and clamps one end of the coverlay <NUM> supplied from the coverlay supply apparatus <NUM>.

Specifically, the coverlay clamp part <NUM> is moved by the transfer body part <NUM> while clamping the coverlay <NUM> separated from the release substrate <NUM> by the separation unit <NUM> of the coverlay supply apparatus <NUM> to transfer the coverlay <NUM> onto the seating table part <NUM>. As shown in <FIG> and <FIG>, the coverlay clamp part <NUM> is opened and closed according to the hydraulic pressure applied to the hydraulic cylinder <NUM> by a pressure control valve (not shown). At this time, the opening and closing speed of the coverlay clamp <NUM> may be adjusted by a speed control valve (not shown) in consideration of the supply speed of the coverlay <NUM> and the moving speed of the transfer body part <NUM>.

In the pre-bonding apparatus <NUM> according to the present invention, the pickup transfer unit <NUM> is positioned to correspond to the position of the coverlay seating unit <NUM>, picks up the coverlay <NUM> seated on the coverlay seating unit <NUM> and waiting, and transfers the same onto the printed circuit board <NUM> supplied from the printed circuit board supply apparatus <NUM>.

Specifically, the pickup transfer unit <NUM> picks up the coverlay <NUM> waiting on the seating table part <NUM> of the coverlay seating unit <NUM> and transfers the picked-up coverlay <NUM> in a direction (e.g., the Y-axis direction) intersecting the loading direction (the X-axis direction) of the coverlay <NUM> supplied from the separation unit <NUM> of the coverlay supply apparatus <NUM>. That is, the picked-up coverlay <NUM> is transferred onto the printed circuit board <NUM> that is temporarily mounted on an aligning table part <NUM> of the aligning table unit <NUM>.

According to an example, as shown in <FIG>, the pickup transfer unit may include a pickup transfer body part <NUM>, a transfer part <NUM>, and a pickup part <NUM>.

The pickup transfer body part <NUM> supports the pickup part <NUM> and reciprocates between the coverlay seating unit <NUM> and the aligning table unit <NUM> by the transfer part <NUM>.

The transfer part <NUM> reciprocates the pickup transfer body part <NUM> in a direction (e.g., the Y-axis direction) intersecting the loading direction (e.g., the X-axis direction) of the coverlay <NUM>.

Specifically, the transfer part <NUM> reciprocates the pickup transfer body part <NUM> between the seating table unit <NUM> and the aligning table unit <NUM>. That is, the pickup transfer body part <NUM> is reciprocally moved from the seating table unit <NUM> to the aligning table unit <NUM> and from the aligning table unit <NUM> to the seating table unit <NUM> by the transfer part <NUM>. Accordingly, the pickup part <NUM> supported by the pickup transfer body part <NUM> moves in a direction (e.g., the Y-axis direction) intersecting the loading direction (the X-axis direction) of the coverlay <NUM> as well. At this time, the coverlay <NUM> picked up by the pickup part <NUM> is transferred from the seating table part <NUM> of the seating table unit <NUM> onto the printed circuit board <NUM> that is stationed on the aligning table part <NUM>. The transfer part <NUM> may include a driving member (not shown) (e.g., a servomotor) and a rail member 322a, and may be configured as another configuration capable of moving a mechanical apparatus straight in the art. In addition, the transfer part <NUM> may include a controller (not shown) capable of precisely controlling the transfer distance of the coverlay <NUM>, that is, the moving distance from the pickup position of the coverlay <NUM> to the position at which the printed circuit board <NUM> is stationed. Such a controller may be configured to be built in a computer and controlled by software.

The pickup part <NUM> is supported by the pickup transfer body part <NUM> to pick up the coverlay <NUM> seated on the coverlay seating unit <NUM>. As shown in <FIG> and <FIG>, the pickup part <NUM> may include a first support member <NUM>, a second support member <NUM>, a third support member <NUM>, a first pickup member <NUM>, a second pickup member <NUM>, a gap adjustment member <NUM>, and a transfer member <NUM>, and may further include a plurality of auxiliary pre-bond members <NUM> and/or a rotational driving member <NUM> as necessary.

The first support member <NUM> is supported on the pickup transfer body part <NUM> by a bracket so as to support the second support member <NUM> and the third support member <NUM>, and has a long shape in the X-axis direction. A rail of the gap adjustment member <NUM> is disposed on the first support member <NUM> in the longitudinal direction (the X-axis direction).

The second support member <NUM> is a part to which the first pickup member <NUM> is mounted, the third support member <NUM> is a part to which the second pickup member <NUM> is mounted, and the second and third support members <NUM> and <NUM> have a long shape in the Y-axis direction. The second support member <NUM> and the third support member <NUM> are movably disposed on the first support member <NUM>, and they are disposed to be spaced apart from each other. Accordingly, the first pickup member <NUM> and the second pickup member <NUM> mounted to the second support member <NUM> and the third support member <NUM>, respectively, may pick up both sides of the coverlay <NUM> seated on the seating table part <NUM> to stably transfer the coverlay <NUM> to the aligning table unit <NUM>. In this case, the separation distance between the second support member <NUM> and the third support member <NUM> may be adjusted by the gap adjustment member <NUM> according to the size (length) of the coverlay in the longitudinal direction (the x-axis direction). Accordingly, the separation distance between the first pickup member <NUM> and the second pickup member <NUM> may be adjusted, thereby further improving pickup stability of the coverlay.

As shown in <FIG>, the first pickup member <NUM> is mounted to the second support member <NUM>, and the second pickup member <NUM> is mounted to the third support member <NUM>. The first pickup member <NUM> and the second pickup member <NUM> may be a plate-shaped member including a plurality of suction pads or a vacuum suction plate having a plurality of vacuum suction holes formed therein.

According to an example, the first pickup member <NUM> and the second pickup member <NUM>, which are vacuum suction plates, may include, for example, a plate that is long in the Y-axis direction and a plurality of vacuum holes formed in the plate. The first pickup member <NUM> and the second pickup member <NUM> may hold/release the coverlay <NUM> according to suction and release of air.

The gap adjustment member <NUM> adjusts the separation distance between the second support member <NUM> and the third support member <NUM>. That is, the gap adjustment member <NUM> drives (moves) the second support member <NUM> and the third support member <NUM> in the X-axis direction, respectively, according to the mark position of the coverlay <NUM> photographed by the first vision unit <NUM>, so that the first pickup member <NUM> and the second pickup member <NUM> are driven (moved) in the X-axis direction. The gap adjustment member <NUM> may include a driving member (not shown) (e.g., a servomotor) and a rail member 3236a, and may be configured as another configuration capable of moving a mechanical apparatus straight in the art. In addition, the gap adjustment member <NUM> may include a controller (not shown) capable of controlling the separation distance between the second support member <NUM> and the third support member <NUM> depending on the size of the coverlay <NUM>. Such a controller may be configured to be built in a computer so to be controlled by software.

The transfer member <NUM> moves the first pickup member <NUM> and the second pickup member <NUM> up and down. The transfer member <NUM> may include a hydraulic cylinder and a pressure control valve for regulating the pressure of the cylinder. Accordingly, the first pickup member <NUM> and the second pickup member <NUM> reciprocate in the Z-axis direction according to the hydraulic pressure applied to the hydraulic cylinder by the pressure control valve. Specifically, the first pickup member <NUM> and the second pickup member <NUM> descend to the coverlay <NUM> waiting on the seating table part <NUM> by the transfer member <NUM> to suck up the coverlay <NUM> and then ascend. Thereafter, when the pickup part <NUM> is transferred to the aligning table part <NUM>, the first pickup member <NUM> and the second pickup member <NUM> descend to the printed circuit board <NUM> stationed (supported) on the aligning table part <NUM> by the transfer member <NUM>, release the coverlay <NUM>, and then ascend. After that, the pickup part <NUM> is transferred back to the seating table part <NUM>. By repeating the above process, the coverlay <NUM> is picked up from the seating table part <NUM> and transferred onto the printed circuit board <NUM> on the aligning table part <NUM>.

In addition, the pickup part <NUM> may further include an auxiliary pre-bond member <NUM> mounted to at least one of the second support member <NUM> and the third support member <NUM> as shown in <FIG>. For example, the auxiliary pre-bond member <NUM> may be mounted to the second support member <NUM> and the third support member <NUM>, respectively. When the coverlay <NUM> picked up by the pickup members <NUM> and <NUM> is transferred onto the printed circuit board <NUM>, the auxiliary pre-bond member <NUM> may pre-bond the transferred coverlay <NUM> to the printed circuit board <NUM> by hot-pressing the same. That is, the coverlay <NUM> and the printed circuit board <NUM> are point-pre-bonded by the auxiliary pre-bond member <NUM>. At this time, the coverlay <NUM> may be more easily detached from the pickup members <NUM> and <NUM> by pressurizing of the auxiliary pre-bond member <NUM>.

According to an example, the first and second auxiliary pre-bond members <NUM> are mounted to the second support member <NUM> and the third support member <NUM>, respectively. Each auxiliary pre-bond member <NUM> is a plate member equipped with a plurality of heater rods 3238a mounted thereto, and is driven up and down. In this case, the first and second auxiliary pre-bond members <NUM> are respectively mounted to the second support member <NUM> and the third support member <NUM> above the first and second pickup members <NUM> and <NUM> so as to be spaced apart from the first and second pickup members <NUM> and <NUM>. At this time, a plurality of through-holes H is formed in each of the first and second pickup members <NUM> and <NUM>, and the heater rods 2338a of the auxiliary pre-bond member <NUM> are mounted to the positions corresponding to the positions of the through-holes. Therefore, according to ascending and descending of the auxiliary pre-bond member <NUM>, the heater rod may pass through the through-hole H to point-pre-bond the coverlay <NUM> to the printed circuit board <NUM>.

Like the above-described first pickup member <NUM> and second pickup member <NUM>, the auxiliary pre-bond member <NUM> ascends and descends in the Z-axis direction by a second transfer member (not shown) including a hydraulic cylinder and a pressure control valve for regulating the pressure of the cylinder. At this time, the auxiliary pre-bond member <NUM> moves up and down together with the first pickup member <NUM> and the second pickup member <NUM> at the same time. However, the vertical movement distance of the auxiliary pre-bond member <NUM> is preferably equal to or greater than the vertical movement distance of the first pickup member <NUM> and the second pickup member <NUM> so as to move further down than the first pickup member <NUM> and the second pickup member <NUM>.

In addition, the pickup part <NUM> may further include a rotational driving member <NUM> for rotating the first support member <NUM> in a direction (Z direction) perpendicular to the printed circuit board <NUM> as shown in <FIG>. When the mark position of the coverlay <NUM> picked up by the first and second pickup members <NUM> and <NUM> is rotated by a predetermined angle from a predetermined reference position, the rotational driving member <NUM> rotates the first support member <NUM> around the vertical direction (Z direction) of the printed circuit board <NUM> to return the coverlay <NUM> to the reference position. Accordingly, an alignment error between the picked-up coverlay <NUM> and the printed circuit board <NUM> may be corrected both in the X-axis direction and in the Y-axis direction. An example of the rotational driving member <NUM> may be a servomotor.

In the pre-bonding apparatus <NUM> according to the present invention, the aligning table unit <NUM> aligns the coverlay <NUM> transferred by the pickup transfer unit <NUM> onto the printed circuit board <NUM> that is automatically and continuously supplied from the printed circuit board supply apparatus <NUM>. At this time, the transfer direction of the coverlay <NUM> and the loading direction of the printed circuit board <NUM> may cross each other. For example, if the transfer direction of the coverlay <NUM> transferred by the pickup transfer unit <NUM> is one direction (e.g., the Y-axis direction), the loading direction of the printed circuit board <NUM> supplied from the printed circuit board supply apparatus <NUM> may be a direction (e.g., the X-axis direction) intersecting the first direction. The aligning table unit <NUM> may automatically and continuously discharge a 1A-composite board 30a in which the transferred coverlay <NUM> is stacked on each unit portion of the printed circuit board <NUM>.

As shown in <FIG>, the aligning table unit <NUM> is disposed adjacent to the seating table part <NUM> of the coverlay seating unit <NUM>. Specifically, the aligning table unit <NUM> is disposed in a direction intersecting the loading direction (e.g., the X-axis direction) of the coverlay <NUM> supplied from the separation unit <NUM> to the coverlay seating unit <NUM> of the pre-bonding apparatus <NUM>, for example, in the Y-axis direction, and is disposed at the point intersecting the loading direction (e.g., the X-axis direction) of the printed circuit board <NUM> supplied from the printed circuit board supply apparatus <NUM>.

According to an example, the aligning table unit <NUM>, as shown in <FIG> and <FIG>, may include an aligning table part <NUM>, and first and second printed circuit board clamp parts 332a and 332b, and may further include an auxiliary pre-bonding part <NUM>, an auxiliary pre-bond transfer part (not shown), and an auxiliary aligning table part <NUM> as necessary.

In the aligning table part <NUM>, the printed circuit board <NUM> supplied from the printed circuit board supply apparatus <NUM> is temporarily stationed (supported), and the coverlay <NUM> transferred over the printed circuit board <NUM> is seated and aligned. Specifically, as shown in <FIG>, the aligning table part <NUM> suction-holds and releases a portion of the printed circuit board <NUM> on which the coverlay <NUM> is disposed (hereinafter referred to as a "unit portion of the printed circuit board) by a vacuum (negative pressure) when the coverlay <NUM> and the printed circuit board <NUM> are aligned, thereby temporarily seating the printed circuit board <NUM>. At this time, the coverlay <NUM> transferred by the pickup transfer unit <NUM> is aligned onto the seated printed circuit board <NUM>.

According to an example, although not shown in the drawing, the aligning table part <NUM> may include: a second plate member; a plurality of second vacuum holes formed in the second plate member; and a second vacuum generation member that is connected to the second vacuum hole through a vacuum line to generate a vacuum.

Like the seating table part <NUM> described above, in the aligning table part <NUM>, as the second vacuum generation member (e.g., a vacuum ejector) applies or releases vacuum pressure (negative pressure) through the vacuum line, a fluid flows or does not flow into the plurality of second vacuum holes. Accordingly, the unit portion <NUM>' of the printed circuit board <NUM> continuously supplied from the printed circuit board supply apparatus <NUM> may be attached to or detached from the second plate member. As described above, the coverlay <NUM> that is picked up and transferred by the pickup transfer part <NUM> is aligned onto the unit portion <NUM>' of the printed circuit board <NUM> seated on the aligning table part <NUM>.

In addition, as shown in <FIG>, the aligning table part <NUM> is divided into a plurality of vacuum regions. As described above, since the vacuum regions of the aligning table part <NUM> are individually separated, a vacuum suction section may be configured according to the size of each unit portion of the printed circuit board on which the coverlay <NUM> is disposed, thereby reducing an error in the alignment between the coverlay and the printed circuit board.

As shown in <FIG>, the first printed circuit board clamp part 332a is disposed to be spaced apart from one end of the aligning table part <NUM> in the width direction of the aligning table part <NUM>, that is, in a direction (e.g., the X-axis direction) intersecting the loading direction of the printed circuit board, and the second printed circuit board clamp part 332b is disposed to be spaced apart from the opposite end of the aligning table part <NUM> while facing the first printed circuit board clamp part 332a. Accordingly, in order to align the coverlay <NUM> to the unit portion <NUM>' of the printed circuit board <NUM> continuously supplied from the printed circuit board supply apparatus <NUM>, the first and second printed circuit board clamp parts 332a and 332b may clamp both portions of the printed circuit board, which are spaced apart from the printed circuit board portion <NUM>' on which the coverlay is disposed.

As shown in <FIG>, the first and second printed circuit board clamp parts 332a and 332b are opened and closed according to the pressure applied to a first cylinder (not shown). In addition, the first and second printed circuit board clamp parts 332a and 332b themselves may ascend and descend by a second cylinder (not shown) depending on the loading height of the supplied printed circuit board <NUM>.

The aligning table unit <NUM> may further include an auxiliary pre-bonding part <NUM> as necessary. As shown in <FIG>, the auxiliary pre-bonding part <NUM> may be installed above the aligning table part <NUM> so as to move up and down, and pre-bond a portion of the coverlay <NUM> transferred by the pickup transfer unit <NUM> to the unit portion <NUM>' of the printed circuit board <NUM> stationed on the aligning table part <NUM>. According to an example, the auxiliary pre-bonding part <NUM> may include a plurality of heater rods installed along the X-axis and/or the Y-axis and connected to each other.

The auxiliary pre-bonding part <NUM> moves up and down by an auxiliary pre-bond transfer part (not shown). That is, the auxiliary pre-bonding part <NUM> is located above the aligning table part <NUM> before the coverlay <NUM> is transferred by the pickup transfer unit <NUM>, and, when the coverlay is aligned with the unit portion <NUM>' of the printed circuit board <NUM> on the aligning table part <NUM> by the pickup transfer unit <NUM>, descends to the aligned coverlay <NUM> to pre-bond the coverlay <NUM> to the unit portion <NUM>' of the printed circuit board <NUM>.

The aligning table unit <NUM> may further include an auxiliary aligning table part <NUM> as necessary. The auxiliary aligning table part <NUM> is disposed at least one of the position between the first printed circuit board clamp part 332a and the aligning table part <NUM> and the position between the second printed circuit board clamp part 332b and the aligning table part <NUM>. The auxiliary aligning table part <NUM> prevents the printed circuit board from sagging when aligning the coverlay <NUM> with the printed circuit board, and assists the first and second printed circuit board clamp parts 332a and 332b to stably clamp the printed circuit board.

In the pre-bonding apparatus <NUM> according to the present invention, the first vision unit <NUM> is disposed between the seating table part <NUM> of the coverlay seating unit <NUM> and the aligning table part <NUM> of the aligning table unit <NUM> so as to be adjacent to the coverlay seating unit <NUM>, and photographs the pickup position of the coverlay picked up by the pickup transfer unit <NUM> to generate a first signal for aligning the position of the coverlay.

Specifically, the first vision unit <NUM> is disposed adjacent to the coverlay seating unit <NUM> between the seating table part <NUM> of the seating unit <NUM> and the aligning table part <NUM> of the aligning table unit <NUM> in order to photograph the bottom surface of the coverlay <NUM> picked up by the pickup transfer unit <NUM>. For example, as shown in <FIG> and <FIG>, the first vision unit <NUM> is disposed under the pickup transfer unit <NUM> in a direction (the X-axis direction) intersecting the transfer direction (e.g., the Y-axis direction) of the coverlay <NUM> transferred by the pickup transfer unit <NUM> so as to be adjacent to the seating table part <NUM> of the coverlay seating unit <NUM>.

The first vision unit <NUM> photographs the bottom surface of the coverlay picked up by the pickup transfer unit <NUM>, recognizes a pickup (mark) position of the coverlay with respect to the bottom surface of the pickup transfer unit <NUM> through image analysis, checks a difference thereof from a predetermined position value, and generates a first signal for aligning the position where the coverlay is to be pre-bonded. An offset value may be applied to the pickup transfer unit <NUM> according to the first signal, so that the first support member <NUM> of the pickup part <NUM> in the pickup transfer unit <NUM> may be aligned by rotating or moving the same left, right, up, and down. Accordingly, the precision of the pre-bond position between the coverlay <NUM> and the printed circuit board <NUM> may be further improved. In particular, when the mark position of the coverlay <NUM> picked up by the pickup transfer unit <NUM> is rotated by a predetermined angle from a reference position, the rotation angle of the coverlay <NUM> is checked by the first vision unit <NUM>, and a signal according to the result is transmitted to the rotational driving member <NUM> capable of rotating the first support member <NUM> of the pickup transfer unit <NUM> around the vertical direction (the Z direction) of the printed circuit board <NUM>, thereby rotating the first support member <NUM> to return to the reference position.

In the pre-bonding apparatus <NUM> according to the present invention, although it is not shown, the second vision unit is positioned to face the aligning table unit <NUM>, and photographs the stationed (seating) position of the printed circuit board supplied to the aligning table unit to generate a second signal for aligning the position where the coverlay transferred by the pickup transfer unit is pre-bonded.

Specifically, the second vision unit photographs the top surface of the printed circuit board <NUM> that is stationed (seated) on the aligning table part <NUM> of the aligning table unit <NUM>, recognizes a mark position of the printed circuit board through image analysis, checks a difference thereof from the mark position of the coverlay <NUM> picked up by the pickup transfer unit <NUM>, and generates a second signal for aligning the position where the coverlay <NUM> is pre-bonded. When an offset value is applied to the pickup transfer unit <NUM> according to the second signal, the transfer distance of the pickup transfer body part <NUM> or the vertical or horizontal movement distance and rotation angle of the first support member <NUM> may be adjusted, thereby further improving the precision of the pre-bond position.

In the pre-bonding apparatus <NUM> according to the present invention, the pre-bonding unit <NUM> pre-bonds the coverlay <NUM> and the printed circuit board <NUM>, which are aligned in the aligning table unit <NUM>. That is, the pre-bonding unit <NUM> pre-bonds the coverlay <NUM> and each unit portion <NUM>' of the printed circuit board of the 1A-composite board 30a automatically and continuously supplied from the aligning table unit <NUM>. Accordingly, it is possible to automatically and continuously obtain a first composite board <NUM> in which the coverlay <NUM> is pre-bonded to each unit portion of the printed circuit board <NUM>.

As shown in <FIG>, the pre-bonding unit <NUM> is disposed adjacent to the aligning table unit <NUM> in a straight line along the loading direction (the Y-axis direction) of the printed circuit board.

According to an example, the pre-bonding unit <NUM>, as shown in <FIG>, may include a pre-bonding housing part <NUM>, an upper support part <NUM>, an upper pre-bonding part <NUM>, a lower support part <NUM>, a lower pre-bonding part <NUM>, and a driving part <NUM>, and may further include first and second pre-bond clamp parts (not shown) as necessary.

The upper support part <NUM> is disposed inside the pre-bonding housing part <NUM> to support the upper pre-bonding part <NUM>. As the upper support part <NUM> is driven up and down by the driving part <NUM>, the upper pre-bonding part <NUM> is also driven up and down. Accordingly, the upper pre-bonding part <NUM> hot-presses the coverlay <NUM> and the printed circuit board <NUM>, which are input and stationed between the upper pre-bonding part <NUM> and the lower pre-bonding part <NUM> from the aligning table unit <NUM>, together with the lower pre-bonding part <NUM>.

The upper pre-bonding part <NUM> is mounted under the upper support part <NUM>, and moves up and down together the upper support part <NUM> according to the vertical movement thereof. The upper pre-bonding part <NUM> hot-presses entire surfaces of the coverlay <NUM> and the front surface of the printed circuit board <NUM>, which are stationed between the upper pre-bonding part <NUM> and the lower pre-bonding part <NUM>, from above when descending, thereby obtaining a first composite board <NUM> on which the coverlay <NUM> and the printed circuit board <NUM> are surface-pre-bonded.

The upper pre-bonding part <NUM> may include a plate member and, if necessary, include a cushion member and/or a release member disposed on the bottom surface of the plate member. The upper pre-bonding part <NUM> may be detached from the upper support part <NUM>, and accordingly, the upper pre-bonding part <NUM> may be removed from the pre-bonding housing part <NUM> to the outside, so a damaged plate member or cushion member may be easily replaced.

The lower support part <NUM> is disposed to face the upper support part <NUM> inside the pre-bonding housing part <NUM> so as to support the lower support part <NUM>.

The lower pre-bonding part <NUM> is above the lower support part <NUM>. That is, the lower pre-bonding part <NUM> is disposed to face the upper pre-bonding part <NUM>. Therefore, like the upper pre-bonding part <NUM>, the lower pre-bonding part <NUM> hot-presses the entire surface of the coverlay <NUM> and the printed circuit board <NUM>, which are stationed between the upper pre-bonding part <NUM> and the lower pre-bonding part <NUM>, from the bottom when the lower pre-bonding part <NUM> descends, thereby form a first composite board <NUM>.

The lower pre-bonding part <NUM>, like the upper pre-bonding part <NUM>, may include a plate member, and may include a cushion member and/or a release member disposed on the bottom surface of the plate member as necessary. In addition, the lower pre-bonding part <NUM> may also be detached from the lower support part <NUM>. Accordingly, since the lower pre-bonding part <NUM> may be removed from the pre-bonding housing part <NUM> to the outside, a damaged plate member or cushion member may be easily replaced.

The driving part <NUM> drives the upper support part <NUM> up and down. The driving part <NUM> includes a hydraulic cylinder 346a and a pressure control valve 346b for regulating the pressure of the hydraulic cylinder. Accordingly, the upper support part <NUM> ascends and descends according to the hydraulic pressure applied to the hydraulic cylinder 346a by the pressure control valve 346b.

Although not shown, the first pre-bond clamp part is disposed to be spaced apart from one end of the pre-bonding housing part <NUM> in the width direction of the pre-bonding housing part <NUM>, that is, in a direction (e.g., the Y-axis direction) intersecting the loading direction of the printed circuit board on which the coverlay is aligned, and the second pre-bond clamp part is disposed to be spaced apart from the opposite end of the pre-bonding housing part <NUM> while facing the first pre-bond clamp part. Therefore, the first and second pre-bond clamp parts may respectively clamp both portions of the 1A-composite board 30a, which are spaced apart from the unit portion of the printed circuit board <NUM>, such that the 1A-composite board 30a continuously and automatically supplied from the aligning table unit <NUM> may be surface-pre-bonded by the upper pre-bonding part <NUM> and the lower pre-bonding part <NUM>.

These first and second pre-bond clamp parts are opened and closed according to the pressure applied to a third cylinder (not shown). In addition, the first and second pre-bond clamp parts themselves may be moved up and down by a fourth cylinder (not shown) depending on the loading height of the supplied 1A-composite board 30a, thereby adjusting positions of the first and second pre-bond clamp parts.

Hot-pressing conditions in the pre-bonding unit <NUM> described above are not particularly limited, and may be, for example, a temperature of about <NUM> to <NUM> and about <NUM> to <NUM> kgf/cm<NUM>. In this case, it is possible to remove a void from the interface between the coverlay <NUM> and the printed circuit board <NUM> during the pre-bonding of the 1A-composite board 30a. The above hot-pressing conditions, the above-described hydraulic pressure of the driving part <NUM>, and opening/closing and position adjustment of the first and second pre-bond clamp parts may be controlled by a controller (not shown). The controller (not shown) may be configured to be built in a computer and controlled by software.

As shown in <FIG> and <FIG>, the transfer apparatus <NUM> is disposed between the pre-bonding apparatus <NUM> and the hot-press apparatus <NUM> and automatically and continuously transfers, to the hot-press apparatus <NUM>, the first composite board <NUM> in which the coverlay <NUM> and the printed circuit board <NUM> are pre-bonded by the pre-bonding apparatus <NUM>. At this time, the transfer apparatus <NUM> supplies the first composite board <NUM> into the hot-press apparatus <NUM> while controlling the supply amount of the first composite board <NUM>.

According to an example, the transfer apparatus <NUM>, as shown in <FIG>, includes a transfer body part <NUM>, a first transfer guide roller part <NUM>, a second transfer guide roller part <NUM>, rail parts <NUM>, a transfer clamp part <NUM>, and a clamp driving part <NUM>.

The transfer body part <NUM> supports the transfer guide roller part <NUM>, the second transfer guide roller part <NUM>, the transfer clamp part <NUM>, and the clamp driving part <NUM>.

The first transfer guide roller part <NUM> is a roller that is installed at one end (e.g., the upper end) of the transfer body part <NUM> and guides the first composite board <NUM> supplied from the pre-bonding apparatus <NUM> to the opposite end (e.g., the lower end) of the transfer body part <NUM>.

The second transfer guide roller part <NUM> is installed at the opposite end (e.g., the lower end) of the transfer body part <NUM> and guides the first composite board <NUM> automatically and continuously supplied from the first transfer guide roller part <NUM> to the hot-press apparatus <NUM>, specifically, to a film guide roller part <NUM> of a protection film supply unit <NUM>. To this end, the second transfer guide roller part <NUM> is further spaced apart from the transfer body part <NUM> than the first transfer guide roller part <NUM>.

The rail parts <NUM> are installed on one surface 410A of the transfer body part <NUM> in the longitudinal direction of the transfer body part <NUM>.

The transfer clamp part <NUM> moves along the rail parts <NUM> and is positioned between the first transfer guide roller part <NUM> and the second transfer guide roller part <NUM> to clamp the first composite board <NUM> supplied from the first transfer guide roller part <NUM>. The transfer clamp part <NUM> moves up and down along the rail part <NUM> while clamping the first composite board <NUM> to transfer the first composite board <NUM> to the second transfer guide roller part <NUM> while controlling the supply amount of the first composite board <NUM>.

Specifically, the hot-pressing time of the first composite board <NUM> in the hot-press apparatus <NUM> is greater than the pre-bonding time of the coverlay <NUM> and the printed circuit board <NUM> in the pre-bonding unit <NUM> of the pre-bonding apparatus <NUM>. Therefore, in the present invention, the supply speed of the first composite board <NUM> from the pre-bonding apparatus <NUM> to the hot-press apparatus <NUM> is adjusted by the vertical movement of the transfer clamp part <NUM> of the transfer apparatus <NUM> disposed between the pre-bonding apparatus <NUM> and the hot-press apparatus <NUM>, thereby controlling the supply amount of the first composite board <NUM>.

That is, when the hot-pressing process is initiated in the hot-press apparatus <NUM>, the transfer clamp part <NUM> of the transfer apparatus <NUM> stops at a position adjacent to the first transfer guide roller part <NUM> in the state of clamping the first composite board <NUM> that is discharged at a constant speed from the pre-bonding unit <NUM> of the pre-bonding apparatus <NUM>. At this time, the first composite board <NUM> discharged at a constant speed from the pre-bonding unit <NUM> of the pre-bonding apparatus <NUM> is clamped by the transfer clamp part <NUM> to be stagnant, instead of being supplied into the hot-press apparatus <NUM>. Afterwards, when the hot-pressing process is completed in the hot-press apparatus <NUM>, the transfer clamp part <NUM> is driven downwards to a configured height along the rail parts <NUM> by the clamp driving part <NUM> in the state of clamping the stagnant first composite board <NUM>. At this time, the configured height is adjusted depending on the stalled length of the first composite board <NUM> that is stalled by the transfer clamp part <NUM>, and the stalled length of the first composite board <NUM> is proportional to the time difference between the pre-bonding process and the hot-pressing process. However, the first composite board <NUM>, which is transferred downwards while being clamped by the transfer clamp part <NUM>, is automatically and continuously supplied into the hot-press apparatus <NUM> faster by a configured driving speed of the transfer clamp part <NUM> than the discharge speed of the first composite board <NUM> discharged from the pre-bonding apparatus <NUM>. Thereafter, when the hot-pressing process is performed on the first composite board <NUM> supplied into the hot-press apparatus <NUM>, the transfer clamp part <NUM> is driven upwards to a configured height along the rail parts <NUM> by the clamp driving part <NUM> after unclamping the first composite board <NUM>, and clamps again the first composite board <NUM> discharged at a constant speed from the pre-bonding unit <NUM> and then stops. As described above, the loading speed of the first composite board <NUM> supplied from the pre-bonding apparatus <NUM> to the hot-press apparatus <NUM> is adjusted according to the vertical driving of the transfer clamp part <NUM> of the transfer apparatus <NUM>, thereby adjusting the supply amount of the first composite board.

The clamp driving part <NUM> is mounted to the transfer body part <NUM> and includes a cylinder and a servomotor to open and close the aforementioned transfer clamp part <NUM>, as well as moving the transfer clamp part <NUM> vertically.

The clamp driving part <NUM> may be controlled by a clamp driving controller (not shown). The clamp driving controller (not shown) controls the clamp driving part <NUM> such that the supply amount of the first composite board <NUM> supplied to the hot-press apparatus <NUM> is delayed depending on the time difference between the pre-bonding time of the pre-bonding apparatus and the hot-pressing time of the hot-press apparatus, and the loading speed of the first composite board <NUM>. Accordingly, the clamp driving part <NUM> drives the transfer clamp part <NUM> up and down to a configured height, and, at this time, adjusts the driving speed and the driving distance when driving the transfer clamp part <NUM> down.

As shown in <FIG> and <FIG>, the hot-press apparatus <NUM> hot-presses the first composite board <NUM> transferred from the pre-bonding apparatus <NUM> by the transfer apparatus <NUM>.

According to an example, the hot-press apparatus <NUM> includes a protection film supply unit <NUM>, a hot-press unit <NUM>, and a protection film collecting unit <NUM> as shown in <FIG>.

The protection film supply unit <NUM> is a part for supplying protection films to the top and bottom of the first composite board <NUM> that is automatically and continuously supplied by the transfer apparatus <NUM>.

According to an example, the protection film supply unit <NUM> includes a first film supply roller part <NUM>, a second film supply roller part <NUM>, and a board guide roller part <NUM> as shown in <FIG>.

The first film supply roller part <NUM> is an unwinder roller that supplies a first protection film <NUM> to the top of the first composite board <NUM> automatically and continuously supplied from the pre-bonding apparatus <NUM> by the transfer apparatus <NUM>. The first film supply roller part <NUM> continuously supplies the first protection film <NUM> to the hot-press unit <NUM> according to the motor driving.

The second film supply roller part <NUM> an unwinder roller that is disposed to face the first film supply roller part <NUM> and supplies a second protection film <NUM> to the bottom of the first composite board <NUM> that is automatically and continuously supplied from the pre-bonding apparatus <NUM> by the transfer apparatus <NUM>. The second film supply roller part <NUM> continuously supplies the second protection film <NUM> to the hot-press unit <NUM> according to the motor driving.

Here, the first and second protection films <NUM> and <NUM> may prevent the surface and/or inside of the first composite board <NUM> from being contaminated with foreign substances when hot-pressing the first composite board <NUM> by the hot-press unit <NUM>, and prevent the resin leaking from the board from contaminating the hot-press unit <NUM>. Therefore, the protection films <NUM> and <NUM> make it possible to increase the operating time and lifespan of the hot-press unit <NUM>. The protection film <NUM> or <NUM> is not particularly limited as long as it is known in the art, and for example, it may be polyethylene terephthalate (PET) or the like.

The board guide roller part <NUM> a guide roller that is disposed between the first film supply roller part <NUM> and the second film supply roller part <NUM> and guides the first composite board <NUM> automatically and continuously supplied from the pre-bonding apparatus <NUM> by the transfer apparatus <NUM> to enter between the first film supply roller part <NUM> and the second film supply roller part <NUM>.

In addition, if necessary, the protection film supply unit <NUM> may further include: a first film guide roller part <NUM> for guiding the first protection film <NUM> supplied from the first film supply roller part <NUM> to be easily disposed on top of the first composite board <NUM> entering between the first film supply roller part <NUM> and the second film supply roller part <NUM>; and a second film guide roller part <NUM> for guiding the second protection film <NUM> supplied from the second film supply roller part <NUM> to be easily disposed on bottom of the first composite board <NUM> entering between the first film supply roller part <NUM> and the second film supply roller part <NUM>. Each of the second and third film guide roller parts may be a plurality of guide rollers.

When the protection films <NUM> and <NUM> are supplied from the protection film supply unit <NUM> in the state of being disposed on top and bottom of the first composite board <NUM>, respectively, the hot-press unit <NUM> hot-presses the same. As shown in <FIG>, the first composite board <NUM>, which is automatically and continuously supplied from the pre-bonding apparatus <NUM> by the transfer apparatus <NUM>, has the first and second protection films <NUM> and <NUM> that are supplied from the protection film supply unit <NUM> and respectively disposed on top and bottom thereof before entering the hot-press unit as described above, and a 1b-composite board <NUM> in such a state is introduced into the hot-press unit <NUM> and hot-pressed, thereby discharging a 2a-composite board <NUM> from the hot-press unit <NUM>. At this time, the 2a-composite board <NUM> includes the first protection film <NUM>/the coverlay <NUM>/the printed circuit board <NUM>/the second protection film <NUM>, and the coverlay <NUM> and the printed circuit board <NUM> is in a hot-pressed state.

For example, the hot-press unit <NUM> includes a hot-press housing part <NUM>, an upper press part <NUM>, and a lower press part <NUM> as shown in <FIG>. However, it is not limited thereto, and any hot-press machine known in the art may be used without limitation.

Here, the upper press part <NUM> and the lower press part <NUM> are respectively disposed inside the hot-press housing part <NUM> to face each other. However, the upper press part <NUM> is vertically driven by a press driving part (not shown). The upper press part <NUM> and the lower press part <NUM> are respectively equipped with a heater block having a built-in heating wire. Therefore, the upper press part <NUM> descends to hot-press the entire surface of the 1b-composite board <NUM> in a structure of the protection film <NUM>/the first composite board <NUM>/the protection film <NUM>, which is stationed between the upper press part <NUM> and the lower press part <NUM>.

At this time, the size of each of the upper press part <NUM> and the lower press part <NUM> of the present invention may be <NUM> or less (specifically, about <NUM> to <NUM>) in length in one direction (e.g., the X-axis direction), and may be <NUM> or less (specifically, about <NUM> to <NUM>) in length in a direction (e.g., the Y-axis direction) perpendicular to the one direction. Therefore, unlike the prior art, the present invention may continuously manufacture a large area 2A-composite board <NUM> by hot-pressing a large area 1b-composite board <NUM>.

The hot-press unit <NUM> may perform preheating to a predetermined temperature and then perform hot-pressing. At this time, the preheating conditions and hot-pressing conditions are not particularly limited. According to an example, for example, the first composite board <NUM> may be preheated under a temperature condition of about <NUM> ~ <NUM> and then hot-pressed under the conditions such as a temperature of about <NUM> to <NUM>, a surface pressure of about <NUM> to <NUM> kgf/Cm<NUM>, and a line pressure of <NUM> to <NUM> kN. In this case, the flow of the resin in the first composite board <NUM> may be maximized, thereby eliminating a void from the board hole.

The protection film collecting unit <NUM>, as shown in <FIG>, collects the protection films <NUM> and <NUM> respectively laminated on top and bottom of the 2A-composite board <NUM> that is hot-pressed by and automatically and continuously supplied from the hot-press unit <NUM>.

The protection film collecting unit <NUM> may include a first film collecting roller part <NUM> and a second film collecting roller part <NUM>, and may further include a film collecting guide roller part <NUM> and/or a pair of ionizer parts (not shown) as necessary, as shown in <FIG>.

The first film collecting roller part <NUM> is a rewinder roller that winds and collects the first protection film <NUM> disposed on top of the 2A-composite board <NUM> that is hot-pressed by and discharged from the hot-press unit <NUM>. The first film collecting roller part <NUM> may continuously wind the first protection film <NUM> according to the motor driving.

The second film collecting roller part <NUM> is a rewinder roller that is disposed to face the first film collecting roller part <NUM> and collects the second protection film <NUM> disposed on bottom of the 2A-composite board <NUM> that is hot-pressed by and discharged from the hot-press unit <NUM>. The second film collecting roller part <NUM> may continuously wind the second protection film <NUM> according to the motor driving.

As described above, the respective protection films <NUM> and <NUM> may be collected by the first film collecting roller part <NUM> and the second film collecting roller part <NUM> to be reused, thereby reducing manufacturing costs.

The film collecting guide roller part <NUM> is disposed between the hot-press unit <NUM> and the first and second film collecting roller parts <NUM> and <NUM>. In this case, the film collecting guide roller part <NUM> may be a plurality of rollers for guiding the first protection film <NUM> and the second protection film <NUM> to the first film collecting roller part <NUM> and the second film collecting roller part <NUM> such that the first protection film <NUM> and the second protection film <NUM> may be easily collected from the 2A-composite board <NUM> discharged from the hot-press unit <NUM> by the first film collecting roller part <NUM> and the second film collecting roller part <NUM>. The film collecting guide roller part <NUM> may adjust the vertical position thereof by a tension controller and a pressure control valve.

The pair of ionizer parts (not shown) is respectively disposed between the first film collecting roller part <NUM> and the second film collecting roller part <NUM> to prevent the generation of static electricity. Specifically, the pair of ionizer parts (not shown) is disposed between the first film collecting roller part <NUM> and the second film collecting roller part <NUM>, and between the hot-press unit <NUM> and the first and second film collecting roller parts <NUM> and <NUM>. In the present invention, the ionizer parts may prevent the generation of static electricity when each protection film is separated and collected from the second composite board <NUM>, thereby reducing a defect rate of the board.

As shown in <FIG> and <FIG>, the winding apparatus <NUM> winds and collects the second composite board <NUM> discharged from the hot-press apparatus <NUM> together with inserted paper (not shown).

According to an example, the winding apparatus <NUM> includes an inserted-paper supply roller part <NUM>, a board collecting roller part <NUM>, and an edge controller <NUM> as shown in <FIG>.

The inserted-paper supply roller part <NUM> is an unwinder roller that supplies inserted paper (not shown) between the second composite boards <NUM> that are discharged from the hot-press apparatus <NUM> to be wound. The inserted-paper supply roller part <NUM> may maintain the tension of the inserted paper constant by a powder clutch, thereby adjusting the supply speed of the inserted paper to be constant.

The board collecting roller part <NUM> is a rewinder roller that collects the second composite board <NUM> discharged from the hot-press apparatus <NUM> together with the inserted paper (not shown). Since the tension of the collected board is kept constant by a load cell and a powder clutch, the board collecting roller part <NUM> may wind the second composite board <NUM> and the inserted paper (not shown) at a constant speed.

The edge controller <NUM> adjusts the position of the board collecting roller part <NUM> depending on the edge positions of the second composite board <NUM> and the inserted paper (not shown) wound by the board collecting roller part <NUM>. According to an example, the edge controller <NUM> may include: a sensor <NUM> (e.g., an ultrasonic sensor) for detecting the left and right movement of the second composite board <NUM> such that the edge of the second composite board <NUM> is evenly wound around the board collecting roller part <NUM> when the second composite board <NUM> and the inserted paper (not shown) are laminated and wound; a control circuit (not shown) for adjusting the left and right movement of the board collecting roller part <NUM> by comparing a signal input by the sensor <NUM> with a predetermined signal and adjusting the amount of amplification; and an actuator (not shown) for adjusting the edge of the second composite board <NUM> to be corrected to a predetermined position according to the signal applied by the control circuit.

Hereinafter, a process of manufacturing a composite board in a roll-to-roll method in a system of manufacturing a composite board according to the present invention will be described in detail with reference to <FIG>.

According to an example of the present invention, a method of manufacturing a composite board includes a coverlay supply step of supplying a coverlay from a coverlay supply apparatus; a printed circuit board supply step of supplying a printed circuit board from the printed circuit board supply apparatus; and a pre-bond step of pre-bonding the coverlay supplied in the coverlay supply step onto the printed circuit board supplied in the printed circuit board supply step to form a first composite board. When manufacturing such a composite board, the above-described system of manufacturing a composite board may be used.

According to another example of the present invention, a method of manufacturing a composite board includes: a coverlay supply step of supplying a coverlay from a coverlay supply apparatus; a printed circuit board supply step of supplying the printed circuit board from the printed circuit board supply apparatus; a pre-bond step of pre-bonding the coverlay supplied in the coverlay supply step onto the printed circuit board supplied in the printed circuit board supply step to form a first composite board; and a hot-press step of hot-pressing the first composite board formed in the pre-bond step to form a second composite board, wherein the supply amount of the first composite board is adjusted when supplying the first composite board formed in the pre-bond step to the hot-press step. When manufacturing such a composite board, the above-described system of manufacturing a composite board may be used.

According to an example, step S100 includes: a step of cutting a coverlay in a coverlay film including a release substrate and the coverlay; and separating the cut coverlay film into the coverlay and the release substrate.

Specifically, a coverlay film <NUM> in which the coverlay <NUM> is laminated on the release substrate <NUM> is wound around the coverlay film supply roller part <NUM> in the form of a roll in the coverlay supply apparatus <NUM>. When the coverlay film supply roller part <NUM> is unwound, the coverlay film <NUM> wound around the coverlay film supply roller part <NUM> is unwound and moves toward the cutting unit <NUM> while being guided by the first guide roller part <NUM>. At this time, the coverlay film <NUM> is supplied with a constant tension by the first tension adjustment roller part <NUM>. As the coverlay film <NUM> passes through the cutting unit <NUM>, the coverlay <NUM> is cut at a predetermined interval.

Thereafter, the coverlay film <NUM> in which the coverlay <NUM> is cut to a predetermined length is separated into the coverlay <NUM>, which is cut to a predetermined size, and the release substrate <NUM> by the separation unit <NUM>. Specifically, a bent portion of a predetermined angle or more is formed in the traveling direction (collecting direction) of the release substrate <NUM> of the coverlay film <NUM> by the delamination plate part <NUM> of the separation unit <NUM>, so that the cut coverlay <NUM> of the coverlay film <NUM> is separated from the release substrate <NUM> and supplied to the pre-bonding apparatus <NUM>. Meanwhile, the release substrate <NUM> separated from the coverlay <NUM> is guided by the release substrate guide roller part <NUM> and collected by the release substrate collecting roller part <NUM>.

(b) A printed circuit board is supplied from a printed circuit board supply apparatus (hereinafter, "step S200").

Step S200 has no temporal sequence relationship with step S100.

The printed circuit board <NUM> is mounted to the printed circuit board supply roller part <NUM> in the form of a roll. Thereafter, the printed circuit board <NUM> is continuously released from the printed circuit board supply roller part <NUM> and guided and supplied to the aligning table unit <NUM> of the pre-bonding apparatus <NUM> by the second guide roller part <NUM> and the second tension adjustment roller part <NUM>. At this time, the printed circuit board <NUM> is supplied with a constant tension by the second tension adjustment roller part <NUM>. Meanwhile, inserted paper interposed between the printed circuit boards <NUM> wound around the printed circuit board supply roller part <NUM> is collected by the inserted-paper collecting roller part <NUM>.

The printed circuit board <NUM> supplied from the printed circuit board supply roller part <NUM> may be cut or spliced with a new printed circuit board by the second splicing part <NUM>.

In addition, when the printed circuit board <NUM> supplied from the printed circuit board supply roller part <NUM> is guided and supplied to the pre-bonding apparatus <NUM> by the second guide roller part <NUM> and the second tension adjustment roller part <NUM>, foreign substances may be removed from the surface thereof by the second cleaning roller part <NUM>.

(c) The coverlay supplied in step S100 is pre-bonded onto the printed circuit board supplied in step S200 to form a first composite board (hereinafter, "step S300").

According to an example, step S300 includes: a step of seating the coverlay supplied from the coverlay supply apparatus <NUM> on the seating table part <NUM> ("step S310"); a step of picking up the coverlay seated on the seating table part, and transferring and aligning the same onto the printed circuit board supplied from the printed circuit board supply apparatus ("step S320 "); and a step of pre-bonding the aligned coverlay and printed circuit board to form a first composite board ("step S330 ").

In step S310, the coverlay <NUM> continuously supplied from the separation unit <NUM> of the coverlay supply apparatus <NUM> is transferred onto the seating table part <NUM> in the state in which one end thereof is clamped by the coverlay clamp part <NUM> of the coverlay seating unit <NUM> to be seated on the seating table part <NUM>. At this time, the coverlay clamp part <NUM> is mounted to the transfer body part <NUM> to reciprocate above the seating table part <NUM>. At this time, the seating table part <NUM> suction-holds and releases the seated coverlay <NUM> by a vacuum (negative pressure). However, since a plurality of vacuum regions are individually separated in the seating table part <NUM>, vacuum suction sections may be configured depending on the size of the coverlay <NUM>.

In step S320, the coverlay <NUM> seated on the seating table part <NUM> is picked up by the pickup transfer unit <NUM>, and transferred and aligned onto the printed circuit board <NUM> supplied from the printed circuit board supply apparatus <NUM>. Step S320 may further include: a step of aligning the position of the coverlay by photographing a mark position of the picked-up coverlay; and a step of aligning the position of the coverlay by photographing a mark position of the picked-up coverlay.

Specifically, the coverlay <NUM> seated on the seating table part <NUM> in a standby state is picked up by the pickup part <NUM> of the pickup transfer unit <NUM>, and then the pickup transfer unit <NUM> moves to the aligning table part <NUM> of the aligning table unit <NUM> by the transfer part <NUM>. At this time, the coverlay <NUM> picked up by the pickup transfer unit <NUM> also moves to the aligning table part <NUM>, and then the coverlay <NUM> is detached from the pickup part <NUM> and aligned onto the printed circuit board <NUM> that is temporarily staying on the aligning table part <NUM>. At this time, the first vision unit <NUM> photographs the pickup (mark) position of the coverlay <NUM> with respect to the pickup transfer unit <NUM>, and compares the difference between the same and a predetermined position value to generate a first signal for aligning the position of the coverlay. In addition, the second vision unit (not shown) photographs the mark position of the printed circuit board <NUM> staying on the aligning table part <NUM>, and compares the same with the mark position of the coverlay <NUM> picked up by the pickup transfer unit <NUM> to generate a second signal for aligning the position where the transferred coverlay <NUM> is to be pre-bonded. By aligning the pickup transfer unit <NUM> picking up the coverlay for moving up, down, left, and right, as well as rotating, by the first signal and the second signal, it is possible to improve pre-bond precision of the coverlay and the printed circuit board in the aligning table part <NUM>.

In step S330, the coverlay <NUM> and the printed circuit board <NUM>, which are aligned in the step S320, are pre-bonded to form a first composite board <NUM>.

Specifically, the laminate of coverlay-printed circuit board formed in step S320 enters between the upper pre-bonding part <NUM> and the lower pre-bonding part <NUM> of the pre-bonding unit <NUM>, and at this time, the upper pre-bonding part <NUM> drives up and down to surface-pre-bond the coverlay <NUM> and the printed circuit board <NUM>. Thereafter, the first composite board <NUM> in which the coverlay and the printed circuit board are pre-bonded is automatically and continuously transferred into the hot-press apparatus <NUM> by the transfer apparatus <NUM>.

(d) However, in the present invention, when supplying the first composite board <NUM> formed in the above-described step S300 to the hot-press apparatus <NUM> in step S400, the supply amount of the first composite board <NUM> is adjusted.

The pre-bonding time of the pre-bonding apparatus <NUM> in the above-described step S300 is shorter than the hot-pressing process time of the hot-press apparatus <NUM> (step S400) in step S400. Therefore, in the present invention, the supply speed of the first composite board <NUM> from the pre-bonding apparatus <NUM> to the press apparatus <NUM> is adjusted according to the vertical movement of the transfer clamp part <NUM> of the transfer apparatus <NUM> disposed between the pre-bonding apparatus <NUM> and the hot-press apparatus <NUM>, thereby adjusting the supply amount of the first composite board <NUM>.

Specifically, in step S300, the first composite board <NUM> is automatically and continuously discharged from the pre-bonding unit <NUM> of the pre-bonding apparatus <NUM> at a constant speed. However, the pre-bonding process time in the pre-bonding unit <NUM> is shorter than the hot-pressing process time in the hot-press unit <NUM> of the hot-press apparatus <NUM>. Accordingly, the first composite board <NUM> discharged from the pre-bonding unit <NUM> is temporarily stopped while being clamped by the transfer clamp part <NUM> of the transfer apparatus <NUM> by the time difference between the pre-bonding process in the pre-bonding unit <NUM> and the hot-pressing process in the hot-press unit <NUM> of the hot-press apparatus <NUM> so as not to be supplied to the hot-press apparatus <NUM>.

Thereafter, when the hot-pressing process by the hot-press apparatus <NUM> is completed in step S300, the transfer clamp part <NUM> is driven downwards to a configured height along the rail parts <NUM> by the clamp driving part <NUM>, and the first composite board <NUM> clamped by the transfer clamp part <NUM> also moves downwards along with the same. At this time, the first composite board <NUM> is transferred into the hot-press apparatus <NUM> at a faster speed by a configured driving speed of the transfer clamp part <NUM> than the speed discharged from the pre-bonding apparatus <NUM> in step S300.

Then, when the hot-pressing process is performed on the first composite board <NUM> transferred into the hot-press apparatus <NUM>, the transfer clamp part <NUM> unclamps the first composite board <NUM> discharged from the pre-bonding apparatus <NUM> and is driven upwards to a configured height along the rail parts <NUM>, and then clamps again the first composite board <NUM> discharged at a constant speed from the pre-bonding unit <NUM> to station the same. Thereafter, the aforementioned up-and-down driving of the transfer clamp part <NUM> repeats.

Through the above process, in the present invention, the transfer speed of the first composite board from the pre-bonding apparatus <NUM> to the hot-press apparatus <NUM> is adjusted, thereby automatically adjust the supply amount of the first composite board <NUM> transferred from the pre-bonding apparatus <NUM> to the hot-press apparatus <NUM>.

(e) The first composite board <NUM>, which is formed in the step S300 and whose supply amount is controlled by the transfer apparatus <NUM>, is hot-pressed to form a second composite board <NUM> (hereinafter, "step S400").

According to an example, step S400 may include: a step of supplying protection films <NUM> and <NUM> to top and bottom of the first composite board <NUM> formed in step S300, respectively; a step of hot-pressing the protection films <NUM> and <NUM> disposed on top and bottom of the first composite board <NUM> to form a 2A-composite board <NUM>; and a step of collecting the protection films <NUM> and <NUM> respectively laminated on top and bottom of the 2A-composite board <NUM>.

Specifically, the protection films <NUM> and <NUM> supplied from the protection film supply unit <NUM>, <NUM>, and <NUM> are disposed on top and bottom of the first composite board <NUM> formed in step S300. Thereafter, the first composite board <NUM> is hot-pressed by the hot-press unit <NUM> in the state in which the protection films <NUM> and <NUM> are disposed on the top and bottom thereof. At this time, the hot-pressing step is performed using the upper and lower press parts <NUM> and <NUM> having a length of <NUM> or less (specifically, about <NUM> to <NUM>) in one direction and a length of <NUM> or less (specifically, about <NUM> to <NUM>) in a direction perpendicular to the one direction to hot-press the entire surface of the first composite board of a large area at once, thereby obtaining the 2A-composite board <NUM>. Thereafter, the protection films <NUM> and <NUM> are collected from the 2A-composite board <NUM>, in which the coverlay and the printed circuit board are hot-pressed, by the protection film collecting unit <NUM>, and a second composite board <NUM> may be discharged.

Thereafter, the second composite board <NUM> formed in step S400 is wound by the board collecting roller part <NUM> of the winding apparatus <NUM> together with inserted paper (not shown) to be collected. At this time, the position of the board collecting roller part <NUM> is adjusted depending on the edge position of the second composite board <NUM> wound around the board collecting roller part <NUM> by the edge controller <NUM> such that the edge of the second composite board <NUM> is evenly wound around the board collecting roller part <NUM>.
