Description

Technical Field

[0001] The present invention relates to the field of circuit board manufacturing, and in particular to a water-cooled UV curing device for plate processing. Background Art

[0002] A UV curing device is a device that uses ultraviolet light (UV) to trigger the rapid curing of photosensitive materials. A UV light source (such as a mercury lamp or UVLED) emits ultraviolet light with a wavelength of 200-400nm, which excites the photoinitiator in the material, triggering the polymerization reaction of monomers and oligomers, and solidifying the liquid material into a solid state within milliseconds to seconds.

[0003] The UV curing unit also includes a cooling system. Water-cooled: A circulating water pump drives coolant (such as deionized water) to remove heat from the lamp, maintaining a stable temperature and suitable for long-term high-load operation.

[0004] ‌PCB substrate‌ is the basic material of printed circuit boards, which carry electronic components and realize electrical connections between them.

[0005] Existing UV curing devices need to use water cooling to dissipate heat during use. However, during heat dissipation, since the heat of the UV curing device is mainly generated by the UV curing lamp, and the heat dissipation channels are mostly arranged near the UV curing lamp, after long-term operation, the temperature of the heat dissipation channels themselves will also rise, resulting in a decrease in the water cooling effect, causing the device to overheat and affect the curing effect.

[0090] Example 2 further optimizes the water-cooled UV curing device for plate processing provided in Example 1. Specifically, Figure 3 and Figure 9 As shown, the curing cleaning module 8 includes:

[0091] A fixed rod 801 is provided on the rectangular frame 7, and the outer wall of the fixed rod 801 is fixedly connected to two fixed platforms 807;

At the same time, cleaning can avoid the heat dissipation channel body 602 and the curing lamp tube body 607 from squeezing dust and other impurities when they contact, thereby avoiding wear on the surface of the curing lamp tube due to squeezing, thereby increasing the service life of the device.

[0101] Example 3 further optimizes the water-cooled UV curing device for plate processing provided in Example 1 or 2. Specifically, Figure 1 、 Figure 2 and Figure 10 As shown, two conveying brackets 3 are each provided with two mounting shafts 11, and the outer walls of the four mounting shafts 11 are fixedly connected to the driving wheels 10, and the outer walls of the two driving wheels 10 on the same side are provided with the same conveyor belt 9, and the outer walls of one side of the two conveying brackets 3 are fixedly connected to the conveying motor 2, and the output shafts of the two conveying motors 2 are respectively connected to one end of two of the mounting shafts 11 through couplings (the conveying motor 2 drives the mounting shaft 11 to rotate, and drives the driving wheel 10 and the conveyor belt 9 to run through the mounting shaft 11).

[0102] The conveyor belt 9, the driving wheel 10 and the conveying motor 2 realize the conveyance of the PCB substrate and its substrate fixture for UV curing operation.

[0103] The use process of the water-cooled UV curing device for plate processing provided by the present invention is as follows:

[0104] When in use, the PCB substrate and the substrate fixture are placed on the conveyor belt 9. At this time, the conveying motor 2 is running, and the conveying motor 2 drives the installation shaft 11 to rotate, and drives the driving wheel 10 and the conveyor belt 9 to run through the installation shaft 11 to convey the PCB substrate and the substrate fixture for UV curing;

[0105] During curing, the curing power supply base 605 is started, and the curing power supply base 605 can provide power to the curing lamp body 607 through the lamp tube pipe 606, so that the curing lamp body 607 performs UV curing on the PCB substrate;

[0106] During curing and heat dissipation, the heat dissipation channel body 602 contacts the curing lamp body 607. At this time, the circulation pump 603 is running, and the circulation pump 603 transports the coolant inside the water-cooled base chamber 610 to the heat dissipation channel body 602, and then transports it back to the water-cooled base chamber 610 as it runs. In this process, the coolant absorbs the heat emitted by the curing lamp body 607 to achieve heat dissipation;

[0107] When the temperature of the heat dissipation channel body 602 rises to a certain temperature, the electric push rod 608 is started, and the electric push rod 608 drives the installation frame 614 to move, and further moves the two connecting parts 613, so that the electric push rod 608 drives the water-cooling base chamber 610 and one end of the heat dissipation channel body 602 to rise until the heat dissipation channel body 602 is separated from the curing lamp body 607. At this time, the servo motor 611 is running, and the servo motor 611 drives the water-cooling base chamber 610 to rotate to switch the heat dissipation channel body 602. After the switching, the electric push rod 608 drives the water-cooling base chamber 610 to reset, and makes the replaced heat dissipation channel body 602 contact with the curing lamp body 607 to ensure the heat dissipation effect;

[0108] After the switch, the electric telescopic rod 615 is operated, and the electric telescopic rod 615 drives the heat dissipation frame 616 to move, so that the original heat dissipation channel body 602 is located inside the heat dissipation frame 616. At this time, the universal motor 622 is started, and the universal motor 622 drives the opening and closing plate 623 to rotate. With the rotation of the opening and closing plate 623 and the thrust applied to the heat dissipation fin group 620 by the telescopic spring 627, the two heat dissipation fin groups 620 are able to approach each other until they contact the original heat dissipation channel body 602, so that the heat dissipation fin group 620 absorbs the heat of the original heat dissipation channel body 602 itself. At the same time, the air pump body 625 is started, and the air pump body 625 transports gas to the air bin 619 through the connecting pipe 624 and discharges it through the air outlet 626, so that the air flow blows the heat dissipation fin group 620 while taking away the heat thereon, so as to quickly dissipate heat from the original heat dissipation channel body 602. After heat dissipation, the device resets.

[0109] During the switching operation, as the heat dissipation channel body 602 separates from the curing lamp tube, the drive motor 809 starts to operate, and the drive motor 809 drives the shaft member 810 to rotate, and cooperates with the sprocket 813 and the chain 811 to make the two winding wheels 812 run synchronously. At this time, the two winding wheels 812 tighten and loosen the two connecting cables 808 respectively, so that one of the connecting cables 808 drives the movable bracket 805 to move on the fixed rod 801 and the limiting guide rod 802. As the movable bracket 805 moves, it can drive the annular frame 803 and the cleaning pad 804 to move, and make the cleaning pad 804 contact with the curing lamp tube body 607 to clean the dust and other impurities on its outer wall.
