Technical Field
[0001] This utility model relates to the field of coating technology, specifically a device for solving the problem of splattering during evaporation vacuum winding coating. Background Technology
[0002] The composite current collector substrate is PET / PP, and copper and aluminum plating are achieved using a vacuum winding coating process. New composite aluminum foil current collectors typically employ evaporative aluminum plating, which involves generating aluminum vapor in a vacuum environment by heating an evaporation boat to approximately 1200°C with molten aluminum wire. This aluminum vapor is then deposited onto the PET / PP substrate.
[0003] In evaporative vacuum roll coating, the resistance-heated evaporation boat generates high-temperature molten aluminum wire to form aluminum vapor that is deposited on the surface of the PET base film. During this process, because the PET base film is close to the evaporation boat, the boiling aluminum liquid on the evaporation boat will also splash onto the surface of the PET base film, causing the PET substrate to be scalded and burned through. In order to avoid this phenomenon, louvers are installed above the evaporation source to prevent aluminum liquid from splashing. However, the louvers are usually fixed with bolts, which is not convenient to operate. Therefore, a device to solve the splashing problem in evaporative vacuum roll coating is designed. Summary of the Invention
[0004] The purpose of this invention is to provide a device for solving the problem of splattering during vacuum evaporation coating, thereby addressing the issue that the conventional method of bolt fixing is not convenient for installing louvers in the prior art.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example: Figure 1 - Figure 5As shown, this utility model provides a technical solution for a device to solve the problem of splattering during vacuum coating in evaporation. The device includes a vacuum chamber 1 with a sealing door 100 installed on the front side. Inside the vacuum chamber 1, there are unwinding rollers 2, a coating drum 4, a winding roller 3, and multiple guide rollers 5. An electrically heated evaporation source module 6 is installed at the bottom of the vacuum chamber 1. A connecting plate 7 is fixedly connected to the top of the electrically heated evaporation source module 6. The connecting plate 7 is fixedly connected to one side inside the vacuum chamber 1. A square groove 70 is formed on the top of the connecting plate 7. Two first bevel gears 18 are provided on the front side of the connecting plate 7. A second bevel gear 19 is meshed with both sides of the connecting plate 7. A rotating rod 20 is fixedly connected between the two second bevel gears 19. A worm gear 22 is fixedly connected to the outside of the rotating rod 20. A worm 23 is meshed with the outside of the worm gear 22. Two fixed blocks 21 are rotatably connected to the outside of the rotating rod 20. The two fixed blocks 21 are symmetrically distributed with respect to the vertical center line of the connecting plate 7. Both fixed blocks 21 are fixedly connected to the connecting plate 7. A connecting block is rotatably connected to the outside of the worm 23. The connecting block is fixedly connected to the front side of the connecting plate 7. A rotating rod 17 is fixedly connected to the rear side of each of the two first bevel gears 18. One end of the rotating rod 17 passes through the front side of the slide block 11 and is rotatably connected to the slide block 11. One end of each rotating rod 17 is fixedly connected to a take-up reel 15. Mounting grooves 9 are provided on both sides of the top of the connecting plate 7. One end of each rotating rod 17 extends into the two mounting grooves 9. Two take-up reels 15 are respectively located inside the two mounting grooves 9. Steel wire ropes 16 are wound inside each of the two take-up reels 15. The top ends of each steel wire rope 16 are fixedly connected to the slide block 11. Two telescopic rods 13 and two first springs 14 are provided at the bottom of each of the two slide blocks 11. Circular grooves 10 are provided at the four corners of the top of the connecting plate 7 for telescopic... Rod 13 is fixedly connected to the bottom of slide block 11. The bottom end of telescopic rod 13 is set inside the circular groove 10 and fixedly connected to connecting plate 7. First spring 14 is sleeved on the outside of telescopic rod 13. The two ends of first spring 14 are fixedly connected to slide block 11 and connecting plate 7 respectively. Slide plate 24 is slidably connected inside both slide blocks 11. Louver 8 is fixedly connected between the two slide plates 24. Square stopper frame 80 is fixedly connected to the bottom of louver 8. Square stopper frame 80 is set inside square stopper groove 70 and contacts connecting plate 7. Limiting structure is provided between louver 8 and two slide blocks 11.
[0022] Specifically, two slide plates 24 are inserted into two slide blocks 11. Then, the worm gear 23 is rotated, and the worm gear 23 meshes with the worm wheel 22. The worm wheel 22 drives two second bevel gears 19 to rotate through the rotating rod 20. The two second bevel gears 19 mesh with two first bevel gears 18 respectively. The two first bevel gears 18 drive two winding reels 15 to rotate through two rotating rods 17. The two winding reels 15 respectively wind up the two steel wire ropes 16. The two slide blocks 11 move downward, multiple first springs 14 are elastically compressed, and multiple telescopic rods 13 retract. The louver 8 is moved downward through the two slide blocks 11 and the two slide plates 24. The square plug bracket 80 is then inserted into the square plug groove 70, completing the quick installation of the louver 8.
[0023] By setting up louvers 8, the splashed molten aluminum can be intercepted. The louvers 8 are tilted and open towards the film, which allows aluminum vapor to pass through normally while completely intercepting the splashed molten aluminum in the vertical direction, protecting the quality of the film. The DC frequency converter power supply set in the electric heating evaporation source module 6 heats the film to a constant temperature of about 1200°C. The intercepted splashed molten aluminum evaporates again when it encounters the high temperature of the louvers 8. Because the presence of louvers 8 reduces the thermal kinetic energy of the aluminum vapor, the high temperature of louvers 8 can provide sufficient kinetic energy for the aluminum vapor passing through its gaps again, ensuring the coating quality. At the same time, the molten aluminum splashed on the louvers 8 can be evaporated again, preventing the louvers 8 from being blocked by aluminum dross accumulation, avoiding the loss of molten aluminum raw materials, and ensuring the utilization rate of molten aluminum raw materials.
[0024] Example: Figure 3 - Figure 5 As shown, the limiting structure includes two limiting grooves 12, which are respectively opened inside the two slides 11. Each of the two limiting grooves 12 is provided with a limiting rod 25. The limiting structure also includes a long groove 26, which is opened on the front side of the louver 8. One end of each of the two limiting rods 25 passes through the outside of the louver 8 and extends into the long groove 26. Both limiting rods 25 are slidably connected to the louver 8. One end of each of the two limiting rods 25 is fixedly connected to a pressing block 28. One side of each of the two pressing blocks 28 is fixedly connected to a second spring 27. One end of each of the two second springs 27 is fixedly connected to the louver 8.
[0025] Specifically, after the two slide plates 24 are inserted into the two slide blocks 11, the two pressing blocks 28 are released by hand, the two second springs 27 are elastically reset, and the two limiting rods 25 are locked into the two limiting grooves 12, so that the louver 8 can continue to be limited so that the position of the square plug plate frame 80 is opposite to the square plug groove 70 for installation.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
