[0023] Preferably, the return belt line device includes a return synchronous belt and a return motor.

[0024] A method for using an automatic UV light curing device for contact lens ink includes the following steps:

[0025] Step 1: Push the loading trolley next to the belt loading device, and manually place the tray outside the loading belt of the belt loading device. The loading belt motor is started to convey the tray from the outside of the loading belt to the inside of the loading belt. The positioning cylinder of the loading belt extends, and the positioning edge of the loading belt positions the tray.

[0026] Step 2: The loading manipulator device is started. The loading lifting cylinder extends to make the loading suction cup suck the tray, and the tray is transferred above the loading transfer platform. The loading lifting cylinder retracts, and the tray is placed on the loading transfer platform. Subsequently, the loading gripper cylinder is started to make the loading gripper grip one group of products in the tray, and this group of products is transferred to the lower die cavity of the fixture on the discharging lifting device. After the placement is completed, the translation module on the discharging lifting device is started to drive the discharging fixture push plate to move, so that the discharging fixture push plate pushes the fixture, and the fixture is pushed below the upper and lower die splitting device. At the same time, the discharging lifting cylinder drives the translation module to move downwards, and the return belt line device pushes the empty fixture to the discharging fixture placement plate of the discharging lifting device. The discharging lifting cylinder moves up to the initial position. The loading manipulator device places a new group of products in the lower die cavity of a new fixture. Every time the discharging lifting device pushes forward a fixture loaded with products, an empty fixture will be replenished from the return belt line device and wait for loading by the loading manipulator device. After the loading manipulator device places all the products in the tray on the loading transfer platform onto the discharging lifting device, the loading manipulator device transfers the empty tray on the loading transfer platform to the transfer belt of the belt transfer device. At this time, the transfer belt motor is started to convey the empty tray to the side close to the unloading manipulator device. The unloading manipulator device transfers the empty tray from the belt transfer device to the unloading transfer platform and waits for loading.

[0027] Step 3: After the fixture reaches below the upper and lower die splitting device, the splitting lifting cylinder extends to make the splitting suction cup suck the upper die of the product, and the splitting lifting cylinder retracts to separate the upper and lower dies of the product. The splitting translation cylinder is started to drive the splitting suction cup to move above the upper die cavity of the fixture, and the splitting lifting cylinder extends to place the upper die of the product on the upper die cavity of the fixture, so as to split the upper and lower dies of the product.

[0028] Step 4: The jig is pushed under the first dust removal device, aligning the lower die cavities of the jig directly below the first air blowing port. The first dust removal lifting cylinder is activated to lower the first dust removal hood onto the jig. The first air blowing nozzle and the first ion wind rod act simultaneously to remove dust from the lower die of the product on the jig. After dust removal is completed, the first dust removal lifting cylinder is activated to raise the first dust removal hood, allowing the jig to continue moving;

[0029] Step 5: The jig is pushed between the first UV curing device and the second UV curing device. The first UV curing lamp and the second UV curing lamp irradiate the lower die of the product simultaneously, rapidly curing the ink on the lower die of the product;

[0030] Step 6: The jig is pushed under the second dust removal device, aligning the lower die cavities of the jig directly below the second air blowing port. The second dust removal lifting cylinder is activated to lower the second dust removal hood onto the jig. The second air blowing nozzle and the second ion wind rod act simultaneously to remove dust from the lower die of the product on the jig. After dust removal is completed, the second dust removal lifting cylinder is activated to raise the second dust removal hood, allowing the jig to continue moving;

[0031] Step 7: The jig is pushed under the upper and lower die clamping device. The clamping lifting cylinder extends to make the clamping suction cup hold the upper die of the product. After the clamping lifting cylinder retracts, the upper die of the product is removed from the upper die cavity of the jig. The clamping translation cylinder is activated to drive the clamping suction cup to move, placing the upper die of the product back into the lower die cavity of the jig to clamp the upper and lower dies of the product;

[0032] Step 8: The blanking gripper cylinder on the blanking manipulator device extends the blanking gripper to hold the product and places it in the tray on the blanking transfer platform. When the tray is full, the blanking lifting cylinder extends to make the blanking suction cup hold the tray and transfers the tray to the belt blanking device;

[0033] Step 9: The jig is pushed onto the pick-up synchronous belt and the pick-up jig placement plate of the pick-up lifting device. The pick-up lifting cylinder descends, driving the jig down to one side of the return belt line device. The pick-up synchronous belt motor is activated to rotate the pick-up synchronous belt to convey the jig to the return belt line device, and the return motor is activated to drive the return synchronous belt to rotate and drive the jig to move;

[0034] Step 10: The jig moves with the return synchronous belt under the third dust removal device, aligning the lower die cavities of the jig directly below the third air blowing port. The third dust removal lifting cylinder is activated to lower the third dust removal hood onto the jig. The third air blowing nozzle and the third ion wind rod act simultaneously to remove dust from the product on the jig. After dust removal is completed, the third dust removal lifting cylinder is activated to raise the third dust removal hood, allowing the jig to continue moving until the jig moves onto the discharging lifting device, completing one cycle of the automatic UV light curing process for the ink;

[0035] Step 11: Repeat the above cycle until all the products in all the trays on the loading trolley are completely cured by UV light. Place all the trays containing the products after UV light curing on the belt unloading device. Start the unloading belt line motor on the belt unloading device to convey all the trays from the inside of the belt unloading device to the outside, and then manually move the trays onto the unloading trolley.

[0036] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0037] The present invention realizes the full-automatic curing of contact lens ink through an automatic UV light curing device for ink. Only manual loading and unloading of trays are required, and the steps involving manual participation are extremely few. The possibility of dust contamination during the curing process is very small, and three dust removal devices are equipped to effectively reduce the impact of dust on the products. The full-automatic UV light curing device for ink can precisely control the UV light intensity and irradiation time, ensuring that the curing effect is more uniform and stable, improving the curing quality and efficiency of the products, reducing the risk of workers contacting hazardous substances, and enhancing work safety.

[0100] Step 1: Push the loading trolley 20 to the side of the belt feeding device 2. Manually place the tray 22 outside the feeding belt 201 of the belt feeding device 2. Start the feeding belt motor 202 to convey the tray 22 from the outside of the feeding belt 201 to the inside of the feeding belt 201. Extend the feeding belt positioning cylinder 203 so that the feeding belt positioning edge 204 positions the tray 22;

[0101] Step 2: Start the loading manipulator device 4. Extend the loading lifting cylinder 402 so that the loading suction cup 401 sucks the tray 22, transfer the tray 22 above the loading transfer platform 3, retract the loading lifting cylinder 402, place the tray 22 on the loading transfer platform 3. Subsequently, start the loading jaw cylinder 404 to make the loading jaw 403 clamp one group of products in the tray 22, transfer this group of products to the lower die cavity 1902 of the fixture 19 on the discharging lifting device 9. After the placement is completed, start the translation module 902 on the discharging lifting device 9 to drive the discharging fixture push plate 904 to move, so that the discharging fixture push plate 904 pushes the fixture 19, and pushes the fixture 19 below the upper and lower die splitting device 10. At the same time, the discharging lifting cylinder 901 drives the translation module 902 to move downwards. The return belt device 16 pushes the empty fixture 19 to the discharging fixture placement plate 903 of the discharging lifting device 9. The discharging lifting cylinder 901 moves up to the initial position. The loading manipulator device 4 places a new group of products in the lower die cavity 1902 of the new fixture 19. Every time the discharging lifting device 9 pushes forward a fixture 19 loaded with products, it will replenish an empty fixture 19 from the return belt device 16 and wait for loading by the loading manipulator device 4. After the loading manipulator device 4 places all the products in the tray 22 on the loading transfer platform 3 onto the discharging lifting device 9, the loading manipulator device 4 transfers the empty tray 22 on the loading transfer platform 3 to the transfer belt 801 of the belt transfer device 8. At this time, start the transfer belt motor 802 to convey the empty tray 22 to the side close to the unloading manipulator device 7. The unloading manipulator device 7 transfers the empty tray 22 from the belt transfer device 8 to the unloading transfer platform 6 and waits for loading;

[0102] Step 3: After the fixture 19 reaches below the upper and lower die splitting device 10, extend the splitting lifting cylinder 1001 so that the splitting suction cup 1003 sucks the upper die of the product. Retract the splitting lifting cylinder 1001 to separate the upper and lower dies of the product. Start the splitting translation cylinder 1002 to drive the splitting suction cup 1003 to move above the upper die cavity 1901 of the fixture 19. Extend the splitting lifting cylinder 1001 to place the upper die of the product on the upper die cavity 1901 of the fixture 19 to split the upper and lower dies of the product;

[0103] Step 4: The jig 19 is pushed under the first dust removal device 11, so that the lower die cavity 1902 of the jig 19 is aligned directly below the first air blowing port 1101. The first dust removal lifting cylinder 1104 is activated to lower the first dust removal hood 1103 so that it presses on the jig 19. The first air blowing nozzle 1102 and the first ion wind rod 1105 act simultaneously to remove dust from the lower die of the product on the jig 19. After the dust removal is completed, the first dust removal lifting cylinder 1104 is activated to raise the first dust removal hood 1103, and the jig 19 continues to move;

[0104] Step 5: The jig 19 is pushed between the first UV curing device 12 and the second UV curing device 17. The first UV curing lamp 1201 and the second UV curing lamp 1701 irradiate the lower die of the product simultaneously, so that the ink on the lower die of the product is quickly cured;

[0105] Step 6: The jig 19 is pushed under the second dust removal device 13, so that the lower die cavity 1902 of the jig 19 is aligned directly below the second air blowing port 1301. The second dust removal lifting cylinder 1304 is activated to lower the second dust removal hood 1303 so that it presses on the jig 19. The second air blowing nozzle 1302 and the second ion wind rod 1305 act simultaneously to remove dust from the lower die of the product on the jig 19. After the dust removal is completed, the second dust removal lifting cylinder 1304 is activated to raise the second dust removal hood 1303, and the jig 19 continues to move;

[0106] Step 7: The jig 19 is pushed under the upper and lower die clamping device 14. The clamping lifting cylinder 1401 extends to make the clamping suction cup 1403 suck the upper die of the product. After the clamping lifting cylinder 1401 retracts, the upper die of the product is taken out from the upper die cavity 1901 of the jig 19. The clamping translation cylinder 1402 is activated to drive the clamping suction cup 1403 to move, and the upper die of the product is placed back into the lower die cavity 1902 of the jig 19 to clamp the upper and lower dies of the product;

[0107] Step 8: The blanking gripper cylinder 704 on the blanking manipulator device 7 extends the blanking gripper 703 to clamp the product and places it in the tray 22 on the blanking transfer platform 6. When the tray 22 is full, the blanking lifting cylinder 702 extends to make the blanking suction cup 701 suck the tray 22 and transfer the tray 22 to the belt blanking device 5;

[0108] Step 9: The jig 19 is pushed onto the blanking synchronous belt 1502 and the blanking jig placement plate 1504 of the blanking lifting device 15. The blanking lifting cylinder 1501 descends, driving the jig 19 to descend to one side of the return belt line device 16. The blanking synchronous belt motor 1503 is activated to rotate the blanking synchronous belt 1502 to convey the jig 19 to the return belt line device 16, and the return motor 1602 is activated to drive the return synchronous belt 1601 to rotate and drive the jig 19 to move;

[0109] Step 10: The jig 19 moves to the lower part of the third dust removal device 18 along with the reflux synchronous belt 1601, aligning the lower die cavity 1902 of the jig 19 directly below the third air blowing port 1801. The third dust removal lifting cylinder 1803 is activated to lower the third dust removal cover 1804 onto the jig 19. The third air blowing nozzle 1802 and the third ion wind rod 1805 act simultaneously to remove dust from the product on the jig 19. After the dust removal is completed, the third dust removal lifting cylinder 1804 is activated to raise the third dust removal cover 1803, allowing the jig 19 to continue moving until it reaches the loading and unloading lifting device 9, thus completing one cycle of the automatic UV curing process of the ink;

[0110] Step 11: Repeat the above cycle until all the products in all the trays 22 on the loading trolley 20 have completed UV curing. Place all the trays 22 containing the products after UV curing on the belt line unloading device 5. The unloading belt line motor 502 of the belt line unloading device 5 is activated to convey all the trays 22 from the inside of the belt line unloading device 5 to the outside. Then, the trays 22 are manually moved onto the unloading trolley 21.
