Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating technology, and in particular to a fully automatic coating device for laser printing substrates. Background Technology
[0002] In photovoltaic manufacturing, the transfer of silver paste onto a substrate is a key process. This process requires first etching the transfer pattern onto the substrate, forming multiple grooves. Current methods typically involve applying silver paste to the entire substrate and then using a scraper to remove excess paste from the substrate surface, leaving only the silver paste within the grooves to complete the transfer.
[0003] However, silver paste has low activity and is difficult to reuse if it is not treated after being applied to the substrate. It requires special recycling. At the same time, the liquid of silver paste is easy to evaporate and dry when spread, which seriously affects its performance for reuse. Currently, there is no effective means to recycle the silver paste scraped off by the doctor blade, which causes serious waste and increases production costs. In addition, the existing coating equipment has a low level of automation and cannot meet the needs of large-scale and high-efficiency production.
[0004] In conclusion, there is an urgent need for a fully automated coating device for laser printing substrates to solve the above problems. Utility Model Content

[0028] When this device is needed, the carrier plate is conveyed to the coating roller 25 via an off-site conveyor mechanism. The first rotary motor 13 and the second rotary motor 14 are started. The output shaft of the first rotary motor 13 rotates, driving the first flat belt 19 to rotate, thereby driving the stirring roller 16 to rotate. The output shaft of the second rotary motor 14 rotates, driving the second flat belt 22 to rotate, thereby driving the feeding roller 15 to rotate. The first rotary motor 13 is controlled to rotate in reverse, driving the above components to rotate in reverse. The stirring roller 16 can stir back and forth, agitating the silver paste in the material box 12. The feeding roller 15 then conveys the agitated silver paste to the coating roller 25. The second lead screw motor 39 is started, and its nut seat moves, driving the moving frame 41 to move along the guide rail 40. The moving frame 41 pushes the support frame upward. 11. Material box 12, first rotary motor 13, second rotary motor 14, feeding roller 15, stirring roller 16, first flat belt 19, second flat belt 22, third rotary motor 23, coating roller 25, third flat belt 27, and fourth flat belt 29 perform a shifting action. After the coating roller 25 shifts to a suitable height, the third rotary motor 23 is started. The output shaft of the third rotary motor 23 rotates, driving the coating roller 25 to rotate through the third flat belt 27 and the fourth flat belt 29, so that the coating roller 25 contacts the carrier plate and evenly coats its surface with a layer of silver paste. Subsequently, the second lead screw motor 39 is controlled to operate in reverse, driving the above components to reset and starting the electric slide rail 9. The electric slider on the electric slide rail 9 drives the moving block 30, connecting rod 31, and second scraper 3. 8 moves backward, opening the first scraper 37 and the second scraper 38. The first lead screw motor 5 is activated, its nut seat moves, driving the connecting plate 7, support plate 8, connecting frame 33, first gear 34, second gear 35, and scraper 36 upward, positioning the scraper 36 above the first scraper 37 and the second scraper 38. The fourth rotary motor 24 is activated, its output shaft rotates, driving the first gear 34 and the second gear 35 to rotate. Through the meshing transmission of the first gear 34 and the second gear 35, the connecting frame 33 and the scraper 36 rotate. The scraper 36 scrapes off the slurry from the surface of the carrier plate, leaving only the slurry in the groove of the carrier plate. Then, the carrier plate is transported back to its initial position via an off-site conveying mechanism. The first lead screw motor 5 is controlled to reverse, driving the above components to reset. The process involves repositioning the scraper 36 back between the first scraper 37 and the second scraper 38, controlling the electric slide rail 9 to reverse, and resetting the above components. This brings the first scraper 37 and the second scraper 38 back into contact with the scraper 36. The first lead screw motor 5 is then activated again, causing the scraper 36 to shift and disengage from the first scraper 37 and the second scraper 38. The first scraper 37 and the second scraper 38 scrape the slurry on the scraper 36 into the material box 12. The stirring roller 16 then stirs and blends the silver paste in the material box 12, achieving silver paste circulation. Finally, the first lead screw motor 5 is reversed, resetting the above components and returning the scraper 36 back between the first scraper 37 and the second scraper 38. This process is repeated on subsequent carriers to complete the coating operation. After coating all carriers...Simply turn off the first lead screw motor 5, the electric slide rail 9, the first rotary motor 13, the second rotary motor 14, the third rotary motor 23, the fourth rotary motor 24, and the second lead screw motor 39.

Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
