Patent Description:
Conventionally, as a tape feeder of this type, a tape feeder has been proposed that feeds a tape (component storage tape) consisting of a bottom tape accommodating a component and a cover tape (top tape) adhered to the upper surface of the bottom tape and supplies a component that can be picked up by a mount device by peeling the cover tape from the bottom tape (refer to Patent Literature <NUM>, for example). The tape feeder includes a take-up roller and a pressing roller for holding the cover tape, a tape take-up mechanism having a motor that rotates the take-up roller, and a collection box disposed behind the tape take-up mechanism. The take-up roller is rotated by driving the motor of the tape take-up mechanism to pull the cover tape rearward and collects the cover tape in the collection box. In addition, the tape feeder applies a predetermined tension to the cover tape by driving the motor of the tape take-up mechanism. Further examples of prior art feeders are disclosed in the Patent Literature documents <NUM>-<NUM>.

However, in the tape feeder described above, when a power supply of the tape feeder is turned off, for example, such as the tape feeder is removed from the mount device, the tension by the motor of the tape take-up mechanism will not be applied to the cover tape. Therefore, the cover tape may be slackened during the time until the tape feeder is removed, and the slackness may cause the cover tape to float in the vicinity of a supply position of the component. In this case, the floated cover tape may interfere with a pickup operation of the component of the mount device, which is not preferable.

There is a main object of the present disclosure to appropriately prevent the cover tape from slackening when the power supply of the tape feeder is turned off.

The present disclosure has taken following means to achieve the main object described above.

A tape feeder of the present disclosure is a tape feeder that feeds a carrier tape consisted of a bottom tape accommodating multiple components and a cover tape adhered to the bottom tape to supply the components, the tape feeder including: a peeling section configured to peel the cover tape from the bottom tape at a position in front of a supply position of the component; a tension applying section configured to apply tension to the cover tape by driving a motor in order to collect the cover tape peeled from the bottom tape; and a holding section configured to hold the cover tape between the peeling section and the tension applying section when a power supply of the tape feeder is turned off and to release the holding of the cover tape when the power supply of the tape feeder is turned on.

The tape feeder according to the present disclosure includes a peeling section that peels off the cover tape from the bottom tape and a holding section that holds the cover tape between the peeling section and the tension applying section that applies tension to the cover tape by driving the motor when the power supply of the tape feeder is turned off, and releases the holding of the cover tape when the power supply is turned on. Therefore, when the power supply is turned off, even when the power supply to the motor is stopped and the tension (holding force) of the cover tape by the tension applying section is released, it is possible to prevent the cover tape from slackening. In addition, when the power supply is turned on, the tension of the cover tape by the tension applying section is not obstructed by the holding section. Accordingly, since it is possible to appropriately prevent the cover tape from slackening when the power supply of the tape feeder is turned off, it is possible to prevent the failure caused by the cover tape floating in the vicinity of the supply position of the component.

Next, embodiments of the present disclosure will be described with reference to the accompanying drawings. <FIG> is a configuration view illustrating a schematic configuration of mount device <NUM>, and <FIG> is a configuration view illustrating a schematic configuration of feeder <NUM>. In the present embodiment, a left-right direction (X-axis), a front-rear direction (Y-axis), and an up-down direction (Z-axis) are as illustrated in <FIG>.

As illustrated in <FIG>, mount device <NUM> includes housing <NUM>, feeder base <NUM>, board conveyance device <NUM>, mounting head <NUM>, and head moving mechanism <NUM>. In feeder base <NUM>, multiple feeders (tape feeders) <NUM> for supplying components are detachably disposed in parallel. Board conveyance device <NUM> is a belt conveyor device, and conveys board S from the left to the right. Mounting head <NUM> holds suction nozzles, picks up components supplied from feeders <NUM> disposed on feeder base <NUM> to the suction nozzles at supply position P, and mounts the components at the mounting position on board S. Head moving mechanism <NUM> moves mounting head <NUM> in XY-directions.

As illustrated in <FIG>, in feeder <NUM>, tape reel <NUM> around which carrier tape 22a is wound is set in feeder main body <NUM>. Carrier tape 22a is consisted of bottom tape 22b in which multiple cavities (recesses) are formed at predetermined intervals in the longitudinal direction and components are accommodated in each of cavities, and cover tape 22c adhered to bottom tape 22b to cover the surface of bottom tape 22b in which components are accommodated in each of cavities. In addition, feeder <NUM> includes tape feeding mechanism <NUM>, tape peeling section <NUM>, tension adjustment mechanism <NUM>, pull-in mechanism <NUM>, collection section <NUM>, clamp mechanism <NUM>, and feeder control section <NUM>.

Tape feeding mechanism <NUM> includes sprocket <NUM> in which engagement claws engaged to the engagement holes of carrier tape 22a are provided on the outer periphery, and driving motor <NUM> such as a servo motor or a stepping motor for driving sprocket <NUM>. In a state where carrier tape 22a is engaged to sprocket <NUM>, tape feeding mechanism <NUM> intermittently rotates sprocket <NUM> by the forward rotation of driving motor <NUM> to feed carrier tape 22a at a pitch toward supply position P of the component. In addition, tape feeding mechanism <NUM> can pull carrier tape 22a back to tape reel <NUM> by the reverse rotation of driving motor <NUM>.

tape peeling section <NUM> is configured to peel cover tape 22c from bottom tape 22b in front of supply position P of the component to expose the components in the cavities. Cover tape 22c peeled by tape peeling section <NUM> is pulled out to be folded back, and is pulled in pull-in mechanism <NUM> through tension adjustment mechanism <NUM> to be collected by collection section <NUM>. In addition, bottom tape 22b from which cover tape 22c is peeled off moves to supply position P in a state where the components are exposed, the components are picked up on mounting head <NUM> (suction nozzle), and bottom tape 22b is guided downward in feeder main body <NUM>. Bottom tape 22b is discharged to the outside from tape discharge port <NUM> below feeder main body <NUM>, is cut by a tape cutting mechanism (not illustrated) at a predetermined cutting position distant from tape discharge port <NUM>, and is collected in dust box <NUM> (refer to <FIG>). In addition, bottom tape 22b discharged to the outside needs to be positioned on dust box <NUM> again without being caught by feeder base <NUM> or the like when feeder <NUM> is once removed from mount device <NUM> and then attached thereto. Therefore, before feeder <NUM> is removed, process that stores bottom tape 22b in feeder main body <NUM> is performed by reversely rotating driving motor <NUM> of tape feeding mechanism <NUM> to pull carrier tape 22a back.

Tension adjustment mechanism <NUM> is a mechanism that adjusts a tension acting on cover tape 22c between tape peeling section <NUM> and pull-in mechanism <NUM>. Tension adjustment mechanism <NUM> includes tension lever <NUM>, guide roller <NUM>, sensor board <NUM>, spring <NUM>, and fixing member <NUM>. Guide roller <NUM> in which fulcrum 32a at one end of tension lever <NUM> is pivotably supported by feeder main body <NUM> and guides cover tape 22c to the other end of tension lever <NUM>, and guide plate 33a (refer to <FIG>) that prevents cover tape 22c from coming off guide roller <NUM> are attached to tension lever <NUM>. When tension lever <NUM> is pivoted up and down around fulcrum 32a, guide roller <NUM> moves up and down in an arc shape. In feeder main body <NUM>, long hole 21a in an arc shaped is formed that guides the movement of the other end (guide roller <NUM>) of tension lever <NUM>. In addition, fixing member <NUM> is fixed to feeder main body <NUM> in the vicinity of the edge of the upper end of long hole 21a.

In addition, tension lever <NUM> is provided with detection piece 32b (refer to <FIG>) extending from the periphery edge portion in an upward direction orthogonal to a direction from one end to the other end, and locking piece 32c (refer to <FIG>) erecting perpendicular from a part of detection piece 32b. Detection piece 32b is located within the detection range of sensor 34a included in sensor board <NUM> when tension lever <NUM> pivots upward around fulcrum 32a, and is positioned outside the detection range of sensor 34a when tension lever <NUM> pivots downward around fulcrum 32a (refer to <FIG>). Sensor board <NUM> detects the presence or absence of detection piece 32b by sensor 34a, that is, the presence or absence of tension lever <NUM>, and outputs a detection signal to feeder control section <NUM>. One end of spring <NUM> is attached to feeder main body <NUM> and the other end thereof is attached to locking piece 32c of tension lever <NUM>, and spring <NUM> biases tension lever <NUM> such that tension lever <NUM> rotates upward. That is, spring <NUM> biases tension lever <NUM> in a direction in which guide roller <NUM> is pressed against cover tape 22c.

Pull-in mechanism <NUM> includes driving motor <NUM> such as a servo motor and a stepping motor, driving gear 43a rotated by driving driving motor <NUM>, driven gear 43b rotated in accordance with the rotation of driving gear 43a, and spring <NUM> that biases driven gear 43b toward driving gear 43a side. Pull-in mechanism <NUM> pulls in cover tape 22c by rotating driving gear 43a with driving motor <NUM> and driven gear 43b and feeds cover tape 22c to the rearward, in a state where cover tape 22c is held between a pair of driving gear 43a. Collection section <NUM> is disposed behind pull-in mechanism <NUM>, and cover tape 22c pulled in and fed by pull-in mechanism <NUM> is collected by collection section <NUM>. Pull-in mechanism <NUM> can hold the rotational positions of the pair of driving gear 43a and driven gear 43b by the holding torque of driving motor <NUM> even when driving motor <NUM> is stopped when the power supply is turned on.

Guide roller <NUM> for guiding cover tape 22c is fixed to feeder main body <NUM> between tape peeling section <NUM> and tension adjustment mechanism <NUM>. Guide roller <NUM> is formed in the same shape as guide roller <NUM>. Cover tape 22c is fed from tape peeling section <NUM> to pull-in mechanism <NUM> in a state where cover tape 22c is in contacted with guide roller <NUM> from below and is stretched to be in contact with guide roller <NUM> from above.

Clamp mechanism <NUM> includes clamp pin <NUM> provided to be able to advance and retract in an obliquely upward direction from an upper end surface of feeder main body <NUM>, and clamp lever <NUM> protruding from an end surface of feeder main body <NUM> and operable in an up-down direction for advancing and retracting clamp pin <NUM>. In clamp mechanism <NUM>, when clamp lever <NUM> is operated to be tilted downward, clamp pin <NUM> is advanced from feeder main body <NUM> (refer to <FIG>), whereas when clamp lever <NUM> is operated to be tilted upward, clamp pin <NUM> is stored in feeder main body <NUM>.

Feeder <NUM> is provided with connectors <NUM> and <NUM> protruding from an end surface of feeder main body <NUM> serving as a rear side of mount device <NUM> and a positioning pin <NUM> of two connectors <NUM> and <NUM>. Although not illustrated, mount device <NUM> is provided with pin holes to which clamp pin <NUM> and each positioning pin <NUM> of feeder <NUM> can be respectively engaged, and connectors to which connectors <NUM> and <NUM> can be respectively connected. Accordingly, when feeder <NUM> is attached to feeder base <NUM> in a state where clamp pin <NUM> is stored in feeder main body <NUM>, positioning pin <NUM> is engaged to the pin hole and connectors <NUM> and <NUM> are respectively connected to each of connectors of mount device <NUM>. In this state, when clamp lever <NUM> is operated to be tilted downward, clamp pin <NUM> is engaged to the pin hole, and feeder <NUM> is locked so as not to be pulled out of feeder base <NUM>. In addition, when clamp lever <NUM> is operated to be tilted upward, the lock of feeder <NUM> is released by pulling out clamp lever <NUM> from the pin hole, so that feeder <NUM> can be detached from feeder base <NUM>. The attachment and detachment of feeder <NUM> may be performed by an operator or may be performed by an exchanging robot capable of automatically exchanging feeder <NUM>. In addition, clamp mechanism <NUM> can detect the advancing and retracting state of clamp pin <NUM>, and outputs the detection signal to feeder control section <NUM>.

Feeder control section <NUM> is configured as a microprocessor including CPU, ROM, RAM, and the like, and controls entire feeder <NUM>. Feeder control section <NUM> outputs a drive signal to driving motor <NUM> of tape feeding mechanism <NUM>, a drive signal to driving motor <NUM> of pull-in mechanism <NUM>, or the like. In addition, feeder control section <NUM> is input a detection signal from sensor board <NUM> of tension adjustment mechanism <NUM> to sensor 34a, a detection signal from clamp mechanism <NUM>, or the like. In feeder <NUM>, feeder control section <NUM> communicates with a control section of mount device <NUM> or receives power from mount device <NUM> through the connection between connectors <NUM> and <NUM> and a connector of mount device <NUM>.

An operation of feeder <NUM>, particularly, an operation of adjusting or holding the tension of cover tape 22c peeled from bottom tape 22b, will be described below. <FIG> is a perspective view illustrating a state of operation of feeder <NUM> when a power supply is turned on, and <FIG> is an enlarged perspective view illustrating a state of operation of tension adjustment mechanism <NUM> when a power supply is turned on. When the power supply of feeder <NUM> that receives power from mount device <NUM> is turned on, feeder control section <NUM> controls pull-in mechanism <NUM> based on the detection signal of sensor 34a input from sensor board <NUM> of tension adjustment mechanism <NUM> to adjust the tension of cover tape 22c. When feeder control section <NUM> detects that tension lever <NUM> is disposed above based on the detection signal of sensor 34a, feeder control section <NUM> performs pull-in control that outputs a driving instruction to driving motor <NUM> such that pull-in mechanism <NUM> pulls in cover tape 22c. As a result, cover tape 22c having an increased tension presses down guide roller <NUM> of tension adjustment mechanism <NUM> downward against the biasing force of spring <NUM>. Tension lever <NUM> stops at a position where the tension of cover tape 22c and the biasing force of spring <NUM> are balanced with each other.

In addition, feeder control section <NUM> outputs a stop instruction to driving motor <NUM>, based on the detection signal of sensor 34a, when it is detected no detection piece 32b, that is, that tension lever <NUM> is disposed below. As described above, since the rotational positions of driving gear 43a and driven gear 43b are held by the holding torque of driving motor <NUM>, it is possible to prevent cover tape 22c from slackening even while driving motor <NUM> is stopped. Then, when feeder <NUM> performs a component supply operation accompanying the feeding of carrier tape 22a by tape feeding mechanism <NUM>, cover tape 22c becomes longer by the amount corresponding to the peeling of cover tape 22c by tape peeling section <NUM>, so that the tension is reduced. Accordingly, tension lever <NUM> pivots upward by the biasing force of spring <NUM>, pushes up cover tape 22c by guide roller <NUM>, and stops at a position where the tension of cover tape 22c and the biasing force of spring <NUM> are balanced with each other. Then, when tension lever <NUM> is detected by sensor 34a, the above-described pull-in control is performed. When the power supply is turned on, feeder <NUM> applies appropriate tension to cover tape 22c by performing these processes to prevent cover tape 22c from slackening.

Next, a time when the power supply of feeder <NUM> is turned off will be described. <FIG> is a perspective view illustrating a state of operation of feeder <NUM> when a power supply is turned off, and <FIG> is an enlarged perspective view illustrating a state of operation of tension adjustment mechanism <NUM> when a power supply is turned off. When the power supply is turned off, the holding torque of driving motor <NUM> of pull-in mechanism <NUM> is not output, and cover tape 22c cannot be held between a pair of driving gear 43a and driven gear 43b. Accordingly, tension lever <NUM> pivots upward by the biasing force of spring <NUM>. In the present embodiment, fixing member <NUM> is disposed above guide roller <NUM>, and tension lever <NUM> pivoted upward stops at a position where guide roller <NUM> contacts fixing member <NUM> via cover tape 22c. As a result, guide roller <NUM> and fixing member <NUM> hold cover tape 22c in a state in which cover tape 22c is held therebetween. Therefore, when the power supply is turned off, it is possible to prevent cover tape 22c from slackening between tape peeling section <NUM> and the holding position of guide roller <NUM> and fixing member <NUM>.

Here, <FIG> is an explanatory view illustrating an example of a state in which cover tape 22c floats. As illustrated in the <FIG>, when cover tape 22c is slackened, cover tape 22c may float in the vicinity of supply position P of the component. In this case, when mounting head <NUM> picks up the components by the suction nozzle with adjacent feeder <NUM> or the like, failures such as interferences of floated cover tape 22c and the suction nozzle occur. In particular, in a case where mounting head <NUM> is configured as a rotary head in which multiple suction nozzles are arranged on the same circumference, since the suction nozzles move in a circumferential direction during a suction operation, the above-mentioned failures are likely to occur, and mount device <NUM> is highly likely to fail. In the present embodiment, since cover tape 22c is held between guide roller <NUM> and fixing member <NUM> when the power supply of feeder <NUM> is turned off, cover tape 22c is prevented from floating, and the above-described failure can be prevented. Cover tape 22c is slackened between pull-in mechanism <NUM> and the holding position of guide roller <NUM> and fixing member <NUM>, but cover tape 22c is only slackened in feeder main body <NUM> and it does not affect the outside. As described above, when the power supply is turned on, the pull-in control is performed when sensor 34a detects detection piece 32b, and since tension lever <NUM> pivots downward, cover tape 22c is not held between guide roller <NUM> and fixing member <NUM>. That is, since the holding cover tape 22c by guide roller <NUM> and fixing member <NUM> is released when the power supply is turned on, the adjustment or collection of the tension of cover tape 22c is not obstructed when the power supply is turned on.

When feeder <NUM> is removed from mount device <NUM>, for example, the power supply is turned off on a condition that the clamp by clamp mechanism <NUM> is released. Even when the power supply of feeder <NUM> is turned off, mounting head <NUM> may perform a component suction operation on feeder <NUM> in the vicinity thereof, and the above-described failures can be prevented during the time until feeder <NUM> that the power supply is turned off is removed. In addition, feeder <NUM> of multiple component types can be set on feeder base <NUM>, and not only feeder <NUM> necessary for the current production but also feeder <NUM> necessary for the next production may be set. In this case, even when the power supply of feeder <NUM> necessary for the next production is turned off in order to suppress the power consumption, the above-described failures can be prevented.

Here, correspondence relationships between constituent elements of the present embodiment and constituent elements of the present disclosure will be clarified. Feeder <NUM> of the present embodiment corresponds to the tape feeder of the present disclosure, tape peeling section <NUM> corresponds to the peeling section, pull-in mechanism <NUM> corresponds to the tension applying section, and fixing member <NUM> that holds cover tape 22c between fixing member <NUM> and guide roller <NUM> included in tension adjustment mechanism <NUM> corresponds to the holding section. Guide roller <NUM> corresponds to the pressing member, spring <NUM> corresponds to the spring, tension adjustment mechanism <NUM> corresponds to the adjustment section, and fixing member <NUM> corresponds to the fixing member. In addition, the pair of driving gear 43a and driven gear 43b correspond to the pair of rotating members, and collection section <NUM> corresponds to the predetermined collecting location. Mount device <NUM> corresponds to the mount device.

In feeder <NUM> described above, when the power supply is turned off, cover tape 22c is held between guide roller <NUM> and fixing member <NUM> of tension adjustment mechanism <NUM> in a position between tape peeling section <NUM> and pull-in mechanism <NUM>, and when the power supply is turned on, the holding of cover tape 22c is released. Therefore, it is possible to prevent cover tape 22c from slackening when the power supply of feeder <NUM> is turned off with a simple configuration, and it is possible to prevent the failure caused by cover tape 22c floating in the vicinity of supply position P of the component.

In addition, guide roller <NUM> can be used for both holding cover tape 22c when the power supply is turned off and adjusting the tension of cover tape 22c when the power supply is turned on, so that the number of components can be suppressed. In addition, feeder <NUM> may rotate carrier tape 22a in a reverse direction in order to store bottom tape 22b in feeder main body <NUM>, so that a reverse rotation prevention mechanism such as a one-way clutch cannot be provided on driving gear 43a and driven gear 43b. Therefore, it is highly meaningful to prevent cover tape 22c from slackening between guide roller <NUM> and fixing member <NUM>.

The present disclosure is not limited to the embodiment that has been described heretofore at all, and needless to say, the present disclosure may be carried out in various modes without departing from the technical scope thereof as long as being within the limits as defined by the appended claims.

For example, in the above embodiment, guide roller <NUM> is used for both holding cover tape 22c when the power supply is turned off and adjusting the tension of cover tape 22c when the power supply is turned on, but the present invention is not limited to this, and a dedicated holding section of cover tape 22c when the power supply is turned off may be provided between tape peeling section <NUM> and tension adjustment mechanism <NUM>. For example, the dedicated holding section includes a pressing member, a spring that biases the pressing member in a direction of pressing the pressing member against cover tape 22c, an electromagnetic section that moves the pressing member against biasing force of the spring by an electromagnetic force, and a fixing member that holds cover tape 22c between the fixing member and the pressing member. When the power supply is turned on, the holding section separates the pressing member from the fixing member by the electromagnetic force of the electromagnetic portion to release holding of cover tape 22c, whereas when the power supply is turned off, the electromagnetic force of the electromagnetic portion is released and the pressing member is pressed against cover tape 22c by the biasing force of the spring to hold cover tape 22c between the pressing member and the fixing member.

In the above embodiment, carrier tape 22a is rotated in the reverse direction in order to store bottom tape 22b in feeder main body <NUM>, but the present invention is not limited to this, and carrier tape 22a may be rotated in the reverse direction for other purposes such as fine adjustment of supply position P.

In the above embodiment, pull-in mechanism <NUM> pulls in cover tape 22c to collection section <NUM> side, but the present invention is not limited to this, and pull-in mechanism <NUM> may pull cover tape 22c into a predetermined location for collecting cover tape 22c. For example, in the same case as bottom tape 22b discharged to the outside and collected, cover tape 22c may be pulled in toward the discharge port thereof.

In the above embodiment, although the tension is applied to cover tape 22c by pulling cover tape 22c in collection section <NUM> side by pull-in mechanism <NUM>, the tension is not limited to this, the tension may be applied to cover tape 22c by driving the motor in order to collect cover tape 22c, such as applying the tension by collecting cover tape 22c while winding cover tape 22c.

Here, the tape feeder of the present disclosure may be configured as follows. The tape feeder according to the present disclosure includes an adjustment section configured to adjust the tension of the cover tape by pressing a pressing member, the adjustment section having the pressing member and a spring that biases the pressing member in a direction of pressing the pressing member against the cover tape between the tension applying section and the peeling section, in which the holding section may be a fixing member fixed to a main body of the tape feeder such that the cover tape is held between the fixing member and the pressing member pressed against the cover tape. In this way, the pressing member of the adjustment section can be used for both holding the cover tape when the power supply is turned off and adjusting the tension of the cover tape when the power supply is turned on, so that the number of components can be suppressed. In addition, since the cover tape is held between the pressing member of the adjustment section and the fixing member fixed to the main body, the cover tape can be prevented from slackening when the power supply is turned off with a simple configuration.

In the tape feeder according to the present disclosure, the tension applying section may be configured to pull the cover tape into the predetermined location by the pair of rotating members rotated by driving the motor in a state that the cover tape is held, and the carrier tape is fed in a direction opposite to a direction in which the carrier tape is fed to the supply position of the component in some cases. When the carrier tape is fed in the reverse direction, the cover tape and the bottom tape are also fed in the reverse direction. Therefore, since a reverse rotation preventing mechanism such as a one-way clutch cannot be provided on the rotating member of the tension applying section, it is highly meaningful to apply the contents of the present disclosure. As an example of the case where the carrier tape is fed in the reverse direction, it is included that when the bottom tape exceeds the supply position of the component, the bottom tape is discharged to the outside from below the main body of the tape feeder, in a case where the bottom tape is cut at a predetermined cutting position, the bottom tape exposed to the outside is returned into the main body by feeding the carrier tape in the reverse direction before the power supply of the tape feeder is turned off.

The mount device of the present disclosure is configured to perform mounting process in which any of the tape feeders described above is detachably attached, and the component supplied from the tape feeder to the supply position is picked up by a pickup member and mounted on a board.

In the mount device of the present disclosure, similarly to the tape feeder described above, it is possible to appropriately prevent the cover tape from slackening when the power supply of the tape feeder is turned off. Therefore, since the cover tape floats in the vicinity of the supply position of the component, it is possible to prevent the occurrence of failures such as interference with the pickup member.

The present disclosure can be applied to a tape feeder, a manufacturing industry of a mount device to which the tape feeder is attached, or the like.
