[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0033] Combined with Figure 1 and Figure 2 , an ultrasonic dust removal device for optical film production of the present utility model includes an outer box 1. The bottom of the inner wall of the outer box 1 is fixedly connected with a bottom plate 2. The middle of the inner wall of the outer box 1 is fixedly connected with a support plate 3. In the middle of the top of the support plate 3, two inclined plates 4 are fixedly connected. A water collecting trough 5 is formed between the left and right sides of the inclined plates 4. The bottom of the water collecting trough 5 is fixedly connected with a water collecting box 6. Slide grooves 18 are formed on both sides of the top of the support plate 3. Slide blocks 19 are slidably connected to the inner walls of the slide grooves 18. The top of the slide block 19 is fixedly connected with a cross bar 20. The bottom of the cross bar 20 is fixedly connected with a tray 21. One side of the tray 21 is fixedly connected with an ultrasonic generator 29. Leakage holes 22 are formed in the bottom of the tray 21. A partition board 23 is arranged at the bottom of the inner wall of the tray 21. The angle of the inclined plate 4 can help move the dust effectively into the water collecting trough 5, preventing them from reattaching to the surface of the optical film. At the same time, the pollutants are concentrated in the water collecting trough 5 and the water collecting box 6, reducing the frequency of cleaning the optical film equipment.

[0034] Combined with Figure 2 , a blowing and drying mechanism is provided at the top of the outer box 1. The blowing and drying mechanism includes two bottom columns 12. A compressed air machine 13 is fixedly connected to the top of the bottom column 12. A motor 14 is fixedly connected to the left side of the compressed air machine 13. A pipe 15 penetrates and is fixedly connected to the rear side of the compressed air machine 13. The other end of the pipe 15 penetrates and is fixedly connected to a nozzle 16. An air suction valve 17 penetrates and is fixedly connected to the right side of the compressed air machine 13. After the optical film is ultrasonically dust-removed, it needs to be properly dried to ensure that there are no water marks or water droplets left on the film surface, so as to maintain its optical quality and performance. The nozzle 16 sprays the high-pressure air in the pipe 15 onto the film surface and dries it in a short time.

[0035] Combined with Figure 3 and Figure 4 , a first water pipe 7 penetrates and is fixedly connected to the bottom of the water collecting box 6. The other end of the first water pipe 7 penetrates and is fixedly connected to a first water pump 8. A filter water tank 9 is fixedly connected to the bottom of the first water pump 8. An ultraviolet lamp 10 is fixedly connected to the side of the inner wall of the filter water tank 9. A microporous membrane filter 11 is fixedly connected to the bottom of the inner wall of the filter water tank 9. A second water pipe 24 penetrates and is fixedly connected to the left side of the filter water tank 9. The other end of the second water pipe 24 penetrates and is fixedly connected to a second water pump 25. A water tank 26 is fixedly connected to the bottom of the second water pump 25. A third water pump 27 is fixedly connected to the top of the water tank 26. A third water pipe 28 penetrates and is fixedly connected to the left side of the third water pump 27. And the other end of the third water pipe 28 penetrates and is fixedly connected to a tray 21. The combined use of the ultraviolet lamp 10 and the microporous membrane filter 11 can effectively improve the efficiency and quality of the cleaning process in the production of optical films. At the same time, it can ensure that the cleaning liquid always remains in a high-purity state, reduce the influence of pollution and impurities in the production process on the quality of the optical film, and improve the production efficiency and product quality.

[0036] Working principle: When in use, the position of the tray 21 is fixed by setting the slider 19 in the chute 18. The optical film is placed on the partition 23 at the bottom of the tray 21 for ultrasonic dust removal. After the dust removal is completed, the partition 23 is taken out, and the cleaning liquid leaks from the water leakage holes 22 at the bottom of the tray 21 to the inclined plate 4, converges into the water collecting tank 5, and then drops into the water collecting box 6. Then, the first water pump 8 transports the used cleaning liquid in the water collecting box 6 to the filtration water tank 9 through the first water pipe 7. The cleaning liquid filters impurities through the microporous membrane filter 11 and is disinfected by the ultraviolet lamp 10 in the tank at the same time. Then, the second water pump 25 extracts the filtered and disinfected cleaning liquid from the bottom of the filtration water tank 9 through the second water pipe 24 and enters the water tank 26. Then, the third water pump 27 transports the clean cleaning liquid to the tray 21 through the third water pipe 28. Thus, an automatic cleaning liquid circulation system is completed. After the optical film is cleaned, the motor 14 is started. The air compressor 13 inhales the air around the suction valve 17, and the processed compressed air is transported to the nozzle 16 through the pipeline 15 to blow-dry the optical film after ultrasonic dust removal, so as to maintain its optical quality and performance.
