Patent Description:
Existing mercury lamp ultraviolet curing device has disadvantages such as high energy consumption, and ozone, dust, and noise during a curing process. With the development of light emitting diode-ultraviolet (LED-UV) semiconductor technology, LED technology is gradually replacing mercury lamps.

LED curing has obvious technical advantages, but there is a demand for ink manufacturers to develop new photoinitiators for LED wavelengths, in order to achieve the best curing and energy-saving effects of the LEDs. At present, we are in a period of alternation between new and old technologies, research and development progress of some inks and varnish photoinitiators cannot fully meet production requirements of the LED-UV In some special printing processes, mercury lamps still cannot be replaced, and thus the mercury lamps still have a certain market.

In this case, in order to take into account energy saving and environmental protection, while ensuring the printing process, there is a demand for both the LED-UV and the conventional mercury lamp in the same curing system. However, since the LED-UV is powered by a direct current (DC) constant current source and dissipates heat through water cooling, and the mercury lamp is powered by an alternate current (AC) power supply and dissipates heat through air cooling, according to the conventional technology, the LED-UV and the mercury lamp hybrid device has to be equipped with two sets of power supplies and cooling devices simultaneously, which will undoubtedly increase complexity of a line connection and increase a volume of the device. Moreover, due to the requirements of the printing process for the use of the two types of lamps, it may be necessary to frequently replace the LED-UVs or the mercury lamps on workstations. In this case, power supply cables and the cooling devices must be replaced together. Therefore, the workload is large and the operation is too cumbersome.

Compared with the prior art, the advantages of the present disclosure are as follows:.

The interchangeable structure of the LED lamp and the mercury lamp of the present disclosure includes the base device, the connector device provided at an end of the base device, and the LED lamp box body and the mercury lamp body that are slidably connected to the base device, respectively. The connector device includes the power supply connector, the air pipe connector, and the water pipe connector. The base device can be mounted on the machine table. The first power connector corresponding to and matching the power supply connector and the nozzle connector corresponding to the water pipe connector are provided at the inner end of the LED lamp box body, and the second power connector corresponding to and matching the power supply connector and the air intake port corresponding to the air pipe connector are provided at the inner end of the mercury lamp body. The power supply connector is electrically connecting to a digital power supply. When the LED lamp box is required for a curing process, the LED lamp box body is inserted into the base device, and then, the LED lamp box body is slid towards the connector device, such that the first power connector is connected to the power supply connector, while the nozzle connector is connected to the water pipe connector, and the digital power supply is switched to supply power to the power supply connector in a DC power supplying mode. In this way, the DC power supplying mode and a water cooling heat dissipation are implemented.

Moreover, the air intake port is communicated with the air pipe connector, and the air pipe connector is connected to a fan through an air pipe. In this case, the digital power supply is switched to an AC power supplying mode, and supplies power to the power supply connector, and then, the fan is started. Therefore, the AC power supply mode and the air cooling heat dissipation mode are implemented. Therefore, only through one insertion operation towards the connector device, the rapid switching between the LED lamp box and the mercury lamp can be implemented. Compared with conventional operations (pulling out cables, a water pipe, screwing and locking, etc.), the operation of the present disclosure is very convenient and efficient, and can greatly improve work efficiency. Moreover, the interchangeable structure shares the same base device, which can adapt to both the LED-UV and the mercury lamp, thus simplifying the device.

Specific embodiments of the present disclosure will be further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present disclosure, but not to limit the scope of the present disclosure.

In the description of the present disclosure, it should be understood that orientation or positional relationships indicated by terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on orientation or positional relationship shown in the drawings, which are merely to facilitate the description of the present disclosure and simplify the description, not to indicate or imply that the device or elements must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be construed as a limitation on the present disclosure. In addition, terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance.

Referring to <FIG>, <FIG> and <FIG>, which schematically show an interchangeable structure of a LED lamp and a mercury lamp according to the present disclosure. The interchangeable structure includes a base device <NUM>, a connector device <NUM>, a LED lamp box body <NUM>, and a mercury lamp body <NUM>. The base device <NUM> is used to be mounted on a machine base. The connector device <NUM> is provided at an end of the base device <NUM>. The LED lamp box body <NUM> and the mercury lamp body <NUM> can be slidably connected to the base device <NUM>. An inner end of the LED lamp box body <NUM> is provided with a first power connector <NUM> and a nozzle connector <NUM>. An inner end of the mercury lamp body <NUM> is provided with a second power connector <NUM> and an air intake port <NUM>. When the LED lamp box body <NUM> and the mercury lamp body <NUM> are mounted and inserted into the base device <NUM>, the first power connector <NUM> and the second power connector <NUM> are arranged opposite to and adapted to a power supply connector <NUM>. In addition, the nozzle connector <NUM> arranged opposite to a water pipe connector <NUM>. The air intake port <NUM> is arranged opposite to an air pipe connector <NUM>. The power supply connector <NUM> is used to be electrically connected to a digital power supply. The digital power supply can selectively supply power to the power supply connector <NUM> in a DC power supplying mode or an AC power supplying mode.

For the interchangeable structure based on the above technical features, when the LED lamp box is required for a curing process, the LED lamp box body <NUM> is inserted into the base device <NUM>, and the LED lamp box body <NUM> is then slid, such that the first power connector <NUM> is connected to the power supply connector <NUM>, while the nozzle connector <NUM> is connected to the water pipe connector <NUM>, and the digital power supply is switched to supply power to the power supply connector <NUM> in the DC power supplying mode. In this way, the power supply connector <NUM> supplies power to the LED lamp box through the first power connector <NUM>, and thus the DC power supplying mode and a water cooling heat dissipation are implemented, and the requirements of the LED lamp box body <NUM> are met. In this embodiment, the digital power supply can be manually switched to the AC power supplying mode or DC power supplying mode. Alternatively, a smart digital power supply can be preferably used to automatically detect whether the LED lamp or the mercury lamp is mounted, and then automatically switches to the AC or DC power supplying mode. When the mercury lamp is required for the curing process, the LED lamp box body <NUM> is pulled out from the base device <NUM> to separate the LED lamp box body <NUM> and the connector device <NUM>, and then, the mercury lamp body <NUM> is inserted into the base device <NUM> and is slid towards the connector device <NUM>, such that the second power connector <NUM> is connected to the power supply connector <NUM>. Moreover, the air intake port <NUM> is communicated with the air pipe connector <NUM>, and the air pipe connector <NUM> is connected to a fan through an air pipe to realize the connection of an air path. In this case, the digital power supply is switched to the AC power supplying mode, and supplies power to the power supply connector <NUM>, and then, the fan is turned on. Therefore, the AC power supply mode and the air cooling heat dissipation mode are implemented. Therefore, it only requires the operations of inserting the LED lamp box main body <NUM> and the mercury lamp body <NUM> to implement the rapid switching between the LED lamp box and the mercury lamp. Compared with conventional operations (pulling out cables, a water pipe, screwing and locking, etc.), the operations of the present disclosure are very convenient and efficient, and can greatly improve work efficiency. Moreover, the interchangeable structure shares the same base device <NUM>, which can adapt to both the LED-UV and the mercury lamp, thus simplifying the device.

It should be noted that curing principles of the LED lamp box body <NUM> and the mercury lamp body <NUM> are known in the prior art, and thus for structures in which the LED-UV lamp source and the mercury lamp are each used to cure a coating (paint), ink, adhesive (glue) or other potting sealants, their detailed internal structures and working principles will not be repeated here.

Preferably, as shown in <FIG>, the base device <NUM> includes opposed guiding rails <NUM> and a bottom plate <NUM> connected to the guiding rail <NUM>. An outer side of the LED lamp box body <NUM> is provided with a first sliding rail <NUM> slidably fitted with the guiding rail <NUM>, such that the LED lamp box body <NUM> can slide freely along the guiding rail <NUM>. An outer side of the mercury lamp body <NUM> is provided with a second sliding rail <NUM> slidably fitted with the guiding rail <NUM>, such that the LED lamp box body <NUM> can slide freely along the guiding rail <NUM>. The connector device <NUM> includes a connector mounting plate <NUM> fixedly connected to a first end of the guiding rail <NUM>. The power supply connector <NUM>, the air pipe connector <NUM>, and the water pipe connector <NUM> are mounted on the connector mounting plate <NUM>. For example, when mounting the LED lamp box body <NUM>, the first sliding rail <NUM> is firstly inserted into the guiding rail <NUM> of the base device <NUM>, and then the LED lamp box body <NUM> is slid towards the connector device <NUM> on the guiding rail <NUM>, such that the inner end of the LED lamp box body <NUM> (such as the right end in <FIG>) is connected to the connector mounting plate <NUM>, the first power connector <NUM> is connected to the power supply connector <NUM>, and the nozzle connector <NUM> is connected to the water pipe connector <NUM>. For example, when mounting mercury lamp body <NUM>, the second sliding rail <NUM> is firstly inserted into the guiding rail <NUM> of the base device <NUM>, and then the mercury lamp body <NUM> is slid towards the connector device <NUM> on the guiding rail <NUM>, such that the inner end of the mercury lamp body <NUM> (such as the right end in <FIG>) is connected to the connector mounting plate <NUM>. In this way, the second power connector <NUM> is connected to the power supply connector <NUM>, and the air intake port <NUM> is connected to the air pipe connector <NUM>.

Further preferably, as shown in <FIG>, both ends of the guiding rail <NUM> are connected to the bottom plates <NUM>, respectively, which is beneficial to enhance the stability of the guiding rail <NUM>. Moreover, an irradiating space is formed between the two bottom plates <NUM>, such that after the LED lamp box body <NUM> or the mercury lamp body <NUM> is slid in place on the guiding rail <NUM>, that is, after the LED lamp box body <NUM> or the mercury lamp body <NUM> is connected to the connector device <NUM>, the process of curing the coating (paint), ink, adhesive (glue) or other potting sealants is implemented through the irradiating space. A second end of the guiding rail <NUM> (the left end in <FIG>) is provided with a plug pin <NUM>. The first sliding rail <NUM> and the second sliding rail <NUM> are each provided with a pin hole matching the plug pin <NUM>. Specifically, the pin hole of the first sliding rail <NUM> is a first pin hole <NUM>, and the pin hole of the second sliding rail <NUM> is a second pin hole <NUM>. In this embodiment, the plug pin <NUM> is preferably adopted as an elastic plug pin <NUM>. In this way, during a sliding process of the LED lamp box body <NUM> and the mercury lamp body <NUM> towards the connector device <NUM>, when the LED lamp box body <NUM> or the mercury lamp body <NUM> starts to contact the connector mounting plate <NUM> on their right side, the elastic plug pin <NUM> is just aligned with the pin hole, and thus the elastic plug pin <NUM> can be inserted into the first pin hole <NUM> or the second pin hole <NUM> automatically, to achieve self-locking. In this way, the LED The lamp box body <NUM> or the mercury lamp body <NUM> is fixed to the base device <NUM>. In this case, the first power connector <NUM> is connected to the power supply connector <NUM>, and the nozzle connector <NUM> is connected to the water pipe connector <NUM>. Alternatively, the second power connector <NUM> is connected to the power source connector <NUM>, and the air intake port <NUM> is connected to the air pipe connector <NUM>. When the LED lamp box body <NUM> or the mercury lamp body <NUM> is required to be detached for interchanging, it is only necessary to pull the elastic plug pin <NUM> outward to separate the plug pin <NUM> from the pin hole, and thus the LED lamp box body <NUM> or the mercury lamp body <NUM> can be freely slid along the base device <NUM>, and thus the LED lamp box body <NUM> or the mercury lamp body <NUM> can be removed from the base device <NUM>. Especially, when the LED lamp box body <NUM> is detached, since the LED lamp box body <NUM> is subjected to a pressure from the water pipe connector <NUM>, the LED lamp box body <NUM> will pop up to the left along the guiding rail <NUM> under the water pressure, which is beneficial to the detachment of the LED lamp box body <NUM>.

Specifically, as shown in <FIG>, the inner end of the LED lamp box body <NUM> is provided with a first inner end cover <NUM>. The first power connector <NUM> and the nozzle connector <NUM> are provided on the first inner end cover <NUM>. When mounting the LED lamp box body <NUM>, the first inner end cover <NUM> is connected to the connector mounting plate <NUM>, such that the first power connector <NUM> is connected to the power supply connector <NUM>, and the nozzle connector <NUM> is connected to the water pipe connector <NUM>. As shown in <FIG>, the inner end of the mercury lamp body <NUM> is provided with a second inner end cover <NUM>. The second power connector <NUM> and the air intake port <NUM> are provided on the second inner end cover <NUM>. When mounting the mercury lamp body <NUM>, the second inner end cover <NUM> is connected to the connector mounting plate <NUM>, such that the second power connector <NUM> is connected to the power supply connector <NUM>, and the air intake port <NUM> is connected to the air pipe connector <NUM>.

As a preferred embodiment, the first inner end cover <NUM> and the second inner end cover <NUM> are both provided with a guiding post facing the connector device <NUM>. The connector device <NUM> is provided with a guiding hole <NUM> corresponding to the guiding post. Specifically, the guiding post of the first inner end cover <NUM> is a first guiding post <NUM>, and the guiding post of the second inner end cover <NUM> is a second guiding post <NUM>. A fitting between the first guiding post <NUM> and the guiding hole <NUM> precedes a contact between the first power connector <NUM> and the power supply connector <NUM>, and a fitting between the second guiding post <NUM> and the guiding hole <NUM> precedes a contact between the second power connector <NUM> and the power supply connector <NUM>. In this way, it can be ensured that when mounting the LED lamp box body <NUM> or the mercury lamp body <NUM>, the first guiding post <NUM> or the second guiding post <NUM> is firstly inserted into the guiding hole <NUM>, which plays a precise positioning function, thus ensuring that preceding inserting the first power connector <NUM> or the second power connector <NUM> into the power supply connector <NUM>, the first power connector <NUM> or the second power connector <NUM> exactly corresponds to the power supply connector <NUM>, so as to avoid an misalignment in positions of the first power connector <NUM> or the second power connector <NUM> and the power supply connector <NUM> due to a gap between the first sliding rail <NUM> or the second sliding rail <NUM> and the guiding rail <NUM>, which misalignment leads to the correct insertion occurs only after multiple plugging and corrections, and causes damage to the power supply connector <NUM>. Further, the first inner end cover <NUM> and the second inner end cover <NUM> are both provided with two guiding posts side by side to further improve the guidance of the LED lamp box body <NUM> and the mercury lamp body <NUM> when being pushed and inserted into the connector device <NUM>, ensuring smooths connection between the connectors.

In this embodiment, the power supply connector <NUM> is a female power supply connector. The first power connector <NUM> and the second power connector <NUM> are both male power supply connectors. During mounting, the first power connector <NUM> or the second power connector <NUM> is inserted into the power supply connector <NUM>, thereby achieving an electrical connection.

Preferably, the nozzle connector <NUM> and the water pipe connector <NUM> are both self-sealing fast connectors. More preferably, the nozzle connector <NUM> is a self-sealing fast male connector, and the water pipe connector <NUM> is a self-sealing fast female connector. As long as the nozzle connector <NUM> is connected to the water pipe connector <NUM>, water can pass through the water pipe. Once the nozzle connector <NUM> is separated from the water pipe connector <NUM>, the nozzle connector <NUM> and the water pipe connector <NUM> will each seal the water flow, such that the water cannot flow out, thereby improving the interchange efficiency.

As a preferred embodiment, outer ends of the LED lamp box body <NUM> and the mercury lamp body <NUM> are both provided with handles. The handle of the LED lamp box body <NUM> is a first handle <NUM>. The handle of the mercury lamp body <NUM> is a second handle <NUM>. Providing the first handle <NUM> and the second handle <NUM> can facilitate the push and pull of the LED lamp box body <NUM> and the mercury lamp body <NUM> during the assembly and disassembly process, which improves the convenience.

It should also be noted that, in the description of the present disclosure, unless otherwise clearly specified and limited, terms "mounted", "connected with", and "connected to" should be understood in a broad sense, for example, it may be a fixed connection or a detachable connection, or integral connection; it may be mechanical connection or electrical connection; it may be direct connection or indirect connection through an intermediate medium, or it may be the internal communication between two elements. For those of ordinary skill in the art, the specific meanings of the above-mentioned terms in the present disclosure can be understood in specific situations.

In summary, only through one inserting operation towards the connector device, the interchangeable structure of the LED lamp and the mercury lamp of the present disclosure can realize the rapid switching between the LED lamp box and the mercury lamp. The operation is quick and convenient, which is beneficial to simplify the device, improves production efficiency. Therefore, the interchangeable structure of the LED lamp and the mercury lamp has a higher promotion and application value.
