Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical film cleaning technology, specifically to a fully automatic optical film forming and cleaning device. Background Technology
[0002] In the field of modern technology, optical films are widely used, playing a key role in many products such as liquid crystal displays (LCDs), organic light-emitting diode displays (OLEDs), touch screens, and solar panels. Their quality directly affects the performance and display effect of these terminal devices.
[0003] As electronic devices continue to develop towards higher resolution, higher definition, and higher sensitivity, the requirements for the surface quality of optical films are becoming increasingly stringent. During the production process, the surface of optical films is extremely prone to adsorbing contaminants such as dust, fibers, and oil. Traditional cleaning methods have many drawbacks. Manual cleaning is extremely inefficient, and the gloves and clothing of operators are prone to shedding fibers, which increases the risk of contamination and makes it difficult to meet the needs of large-scale production. Simple mechanical cleaning equipment, such as ordinary brush cleaning devices, can only remove larger particles of impurities and is powerless against tiny particles and contaminants adsorbed by electrostatics.
[0004] In some high-precision optical film applications, such as optical films used in high-end smartphone displays, the number of particles allowed per square centimeter of surface must be controlled at an extremely low level. Traditional cleaning methods are far from meeting this standard. In addition, with increasingly stringent environmental protection requirements, some chemical cleaning agents used in traditional cleaning methods may pollute the environment, and subsequent treatment costs are high.
[0005] Meanwhile, in the context of increasingly fierce market competition, optical film manufacturers need to continuously improve production efficiency, reduce production costs, and enhance product quality to strengthen their competitiveness. Therefore, developing a fully automatic optical film cleaning equipment that can efficiently and thoroughly clean the surface of optical films, and is environmentally friendly and highly automated, has important practical significance and urgent market demand.
[0006] Traditional cleaning methods often rely on manual wiping or simple mechanical cleaning devices. Manual wiping is inefficient and can easily introduce new contaminants, such as fibers and dust, which can damage the surface quality of optical films. To address this, we propose a fully automated optical film forming and cleaning device. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0027] Please see Figure 1-4 An automated optical film forming and cleaning device includes a workbench 1 and support legs 2. Two sets of parallel support legs 2 are fixedly installed on the bottom of the workbench 1. A first fixed plate 3 is fixedly installed on one side of the top of the workbench 1. A second fixed plate 4 is fixedly installed on the other side of the top of the workbench 1 corresponding to the first fixed plate 3. The first fixed plate 3 and the second fixed plate 4 are parallel vertical plates. A sliding structure is provided between the two inner sides of the first fixed plate 3 and the second fixed plate 4. A support frame 9 is slidably connected to the sliding structure. The support frame 9 is L-shaped. A cleaning liquid storage structure is provided on the top of the horizontal part of the L-shaped support frame 9. A cleaning structure is provided on the lower surface of the L-shaped support frame 9. A lifting structure is provided on the top of the workbench 1 and directly below the cleaning structure.
[0028] Furthermore, the sliding structure includes a rotating structure and a moving structure. The rotating structure includes a servo motor 5, a threaded column 6, and a ball bearing 7. The servo motor 5 is fixedly installed on the outer side of the first fixed plate 3. The output shaft of the servo motor 5 passes through the side wall of the first fixed plate 3 and is fixedly connected to the threaded column 6. The other end of the threaded column 6 is rotatably installed on the side of the second fixed plate 4 through the ball bearing 7.
[0029] Furthermore, the moving structure includes a slide rod 8 and a slide groove 10. The slide rod 8 is fixedly installed on the top of the worktable 1, and the two sides of the slide rod 8 are fixedly connected to the opposing sides of the first fixed plate 3 and the second fixed plate 4. The bottom of the support frame 9 is provided with a slide groove 10. The support frame 9 is slidably installed on the top of the slide rod 8 through the slide groove 10. The support frame 9 is provided with a through threaded hole above the slide groove 10. The support frame 9 is threadedly connected to the threaded post 6 through the threaded hole. When the servo motor 5 is started, its output shaft drives the threaded post 6 to rotate. Since the support frame 9 is slidably connected to the slide rod 8 through the slide groove 10 at the bottom, and the threaded hole on the support frame 9 is threadedly connected to the threaded post 6, when the threaded post 6 rotates, the support frame 9 will move horizontally along the slide rod 8. This allows the cleaning structure to cover the entire surface of the optical film, ensuring thorough cleaning.
[0030] Furthermore, the cleaning fluid storage structure includes a cleaning fluid storage tank 11 and a storage tank cover 12. The cleaning fluid storage tank 11 is fixedly installed on the top of the support frame 9L type, and the storage tank cover 12 is fixedly installed on one side of the top of the cleaning fluid storage tank 11. The cleaning fluid is stored in the cleaning fluid storage tank 11, and the storage tank cover 12 can prevent the cleaning fluid from evaporating and becoming contaminated.
[0031] Furthermore, the cleaning structure includes a pump 13, a connecting pipe 14, a fixed support pipe 15, a cleaning tray 16, and a cleaning sponge 17. The pump 13 is fixedly installed on the top center of one side of the storage tank cover 12. The fixed support pipe 15 is fixedly installed on the top of the support frame 9 corresponding to the side of the cleaning liquid storage tank 11. The pump 13 is fixedly connected to the fixed support pipe 15 through the connecting pipe 14. A cleaning sponge 17 is fixedly connected to one bottom end of the fixed support pipe 15. A set of parallel cleaning sponges 17 are fixedly installed at the bottom of the cleaning sponge 17. When the equipment is started, the extraction pump 13 starts working, drawing the cleaning fluid from the cleaning fluid storage tank 11 through the connecting pipe 14 and delivering it to the fixed support pipe 15. The cleaning fluid flows along the fixed support pipe 15 to the cleaning sponge 17. The cleaning sponge 17 has cleaning ability because it absorbs the cleaning fluid. During the movement of the support frame 9, the cleaning sponge 17 comes into contact with the surface of the optical film. Through its soft material and the absorbed cleaning fluid, it wipes and absorbs the tiny particles, dust, oil and other contaminants on the surface of the optical film, thereby achieving the purpose of cleaning.
[0032] Furthermore, the lifting structure includes a telescopic cylinder 18 and an optical film placement tray 19. The telescopic cylinder 18 is fixedly installed on the top of the workbench 1, and the optical film placement tray 19 is fixedly installed on the top of the telescopic cylinder 18. The top of the optical film placement tray 19 has multiple sets of linearly distributed optical film placement slots 20. The optical film to be cleaned is placed in the optical film placement slots 20 on the top of the optical film placement tray 19. The optical film placement slots 20 can position the optical film and prevent it from shifting during the cleaning process. During the cleaning process, the telescopic cylinder 18 can telescopically extend and retract as needed. When it is necessary to adjust the contact pressure between the optical film and the cleaning structure or to perform cleaning operations at different heights, the telescopic cylinder 18 drives the optical film placement tray 19 to rise or fall, so that the optical film and the cleaning sponge 17 maintain a suitable contact state, further ensuring the stability and consistency of the cleaning effect.
[0033] Working Principle: First, place the equipment in a suitable working area. The support feet 2 stabilize the worktable 1. Place the optical film to be cleaned into the optical film placement slot 20 on top of the optical film placement tray 19. The optical film placement slot 20 positions the optical film, preventing displacement during cleaning. The cleaning solution storage tank 11 contains cleaning solution, and the tank cover 12 prevents evaporation and contamination. When the equipment is started, the extraction pump 13 begins operation, drawing the cleaning solution from the cleaning solution storage tank 11 through the connecting pipe 14 and delivering it to the fixed support pipe 15. The cleaning solution flows along the fixed support pipe 15 to the cleaning sponge 17. The cleaning sponge 17 absorbs the cleaning solution and acquires cleaning ability. During the movement of the support frame 9, the cleaning sponge 17 comes into contact with the surface of the optical film. Through its soft material and absorbed cleaning solution, it cleans the film. The optical film surface is wiped and adsorbed to remove tiny particles, dust, oil, and other contaminants, thus achieving the cleaning purpose. The servo motor 5 is started, and its output shaft drives the threaded column 6 to rotate. Since the support frame 9 is slidably connected to the slide rod 8 through the bottom slide groove 10, and the threaded hole on the support frame 9 is threadedly connected to the threaded column 6, the support frame 9 will move horizontally along the slide rod 8 when the threaded column 6 rotates. This allows the cleaning structure to cover the entire surface of the optical film, ensuring thorough cleaning. During the cleaning process, the telescopic cylinder 18 can extend and retract as needed. When it is necessary to adjust the contact pressure between the optical film and the cleaning structure or to perform cleaning operations at different heights, the telescopic cylinder 18 drives the optical film placement tray 19 to rise or fall, so that the optical film and the cleaning sponge 17 maintain a suitable contact state, further ensuring the stability and consistency of the cleaning effect.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
