Description

Technical Field

[0001] This utility model relates to the field of film application technology, specifically to a film application device with precise positioning. Background Technology

[0002] A film applicator is a device specifically designed for industries such as electronics, communications, and semiconductors. It is mainly used to apply protective films and explosion-proof films, ensuring that there are no bubbles or scratches during the application process.

[0003] In the existing technology, screen protector application is a common product protection method applicable to a variety of products, such as applying screen protectors to mobile phone screens. The main purpose is to protect the product surface, enhance performance, or improve aesthetics. Therefore, screen protectors need to be applied before mobile phone screens are put into use. In order to apply screen protectors quickly in batches, screen protector application machines are generally used.

[0004] However, for the sake of efficiency and convenience, screen protector applicators are usually equipped with belt conveyors to transport the phone screens to be covered. Since the screen protector applicator itself vibrates during operation, it can easily cause the belt conveyor to shake, resulting in the phone screens on the belt conveyor shifting and making the screen protector application inaccurate.

[0005] Based on this, the present invention designs a film-applying device with precise positioning to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a film application device with precise positioning.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a precise positioning film application device, including a film application machine, and further including a film slitting component and a screen conveying component;

[0008] The laminating machine is equipped with a film slitting component that can uniformly cut the film.

[0009] The screen protector applicator is equipped with a screen conveying assembly that can transport the mobile phone screen to be covered at a constant speed.

[0010] The film slitting assembly is located above the screen conveying assembly, but the film slitting assembly and the screen conveying assembly are not directly connected.

[0011] The film slitting assembly includes a linkage slitting assembly and a film feeding assembly. Both the linkage slitting assembly and the film feeding assembly are connected to the inner wall of the laminator. The linkage slitting assembly and the film feeding assembly are driven together. The linkage slitting assembly is located in front of the film feeding assembly, and the film feeding assembly is closer to the take-up roller located at the rear of the laminator.

[0012] Furthermore, the film feeding assembly includes a drive gear, an upper roller, a first motor, and a lower roller. The upper roller and the lower roller are rotatably disposed inside the laminating machine, and there is a gap between the upper roller and the lower roller. One end of the upper roller is fixed with a drive gear, which is located inside the laminating machine. The other end of the upper roller is fixedly connected to the output end of the first motor, which is located outside the laminating machine and is fixed to the outer surface of the laminating machine.

[0013] Furthermore, rubber sleeves are fixed to the outer surfaces of both the upper and lower rollers, which will compress the film.

[0014] Furthermore, the linkage slitting assembly includes a tripod, a first transmission rod, a lowering rod, a slitting blade, a second transmission rod, a third transmission rod, and a transmission gear. The tripod, the lowering rod, and the transmission gear are rotatably mounted on the inner wall surface of the laminating machine. The third transmission rod is fixedly mounted on the side surface of the transmission gear. The second transmission rod is rotatably connected to the end of the tripod and the end of the third transmission rod. The first transmission rod is rotatably connected to the end of the tripod and the lowering rod. The slitting blade is fixed to the end surface of the lowering rod.

[0015] Furthermore, the tripod is a right-angled triangle, the second transmission rod is rotatably connected to the 30-degree end of the tripod, the right-angle end of the tripod is rotatably connected to the inner wall of the laminating machine, and the first transmission rod is rotatably connected to the 60-degree end of the tripod.

[0016] Furthermore, the driving gear corresponds to and meshes with the transmission gear, and the diameter of the driving gear is larger than the diameter of the transmission gear.

[0017] Furthermore, the screen conveying assembly includes a belt conveyor, a positioning plate, a worm gear, a worm wheel, a second motor, a movable plate, and a rectangular plate. The belt conveyor is fixedly installed on the bottom surface inside the laminating machine. The worm wheel is rotatably disposed on the upper surface inside the laminating machine. The worm gear is rotatably disposed inside the laminating machine, and the worm wheel and worm gear are meshed together. The second motor is fixed on the outer surface of the laminating machine, and the output end of the second motor is fixedly connected to the end of the worm gear. The rectangular plate is fixed on the lower surface of the worm wheel. One end of the movable plate is rotatably connected to the end of the rectangular plate, and the other end of the movable plate is rotatably connected to the upper surface of the positioning plate. The positioning plate is slidably disposed on the upper surface of the belt conveyor.

[0018] Furthermore, the worm gear is located above the middle position of the belt conveyor, and multiple sets of rollers are rotatably arranged inside the positioning plate.

[0019] Compared with the prior art, the advantages of this utility model are as follows: 1. The mobile phone screen to be coated is placed on the belt conveyor, and the second motor is started to drive the worm gear to rotate. The rotation of the worm gear will drive the worm wheel to rotate, and the rotation of the worm wheel will drive the rectangular plate to rotate. Since the rectangular plate is relatively long, the rotation of the rectangular plate will pull the positioning plate through the movable plate, so that the two sets of symmetrical positioning plates move towards each other. Since the guide rod fixed inside the belt conveyor is slidably connected to the protrusion fixed at the upper end of the positioning plate, the positioning plate will not deviate when moving until the side surface of the two sets of positioning plates contacts the side surface of the mobile phone screen. At this time, the positioning plate plays a positioning role for the mobile phone screen, avoiding the deviation of the mobile phone screen when the belt conveyor is transporting it.

[0020] 2. At the same time, the positioning plate does not directly contact the mobile phone screen. Instead, the mobile phone screen is contacted by a roller that is rotated and installed inside the positioning plate. Therefore, the connection between the mobile phone screen and the positioning plate is not a sliding connection but a rolling connection, which greatly reduces the friction between the mobile phone screen and the positioning plate and avoids the belt conveyor from affecting the conveying of the mobile phone screen due to excessive friction.

[0021] 3. When slitting the film, the first motor is started to drive the upper roller to rotate. Since the film is located between the upper and lower rollers, and the outer surfaces of the upper and lower rollers are fixed with rubber sleeves, the friction between the upper and lower rollers and the film increases. Therefore, when the upper roller rotates, it will pull the film, causing the film to move towards the linkage slitting assembly. The rotation of the upper roller will drive the drive gear to rotate, which will drive the transmission gear to rotate, which will drive the third transmission rod to rotate. The rotation of the third transmission rod will pull the second transmission rod to move. The movement of the second transmission rod will pull the tripod to move through the connection with the tripod, causing the uppermost corner of the tripod to rotate slightly on the inner wall of the laminator, thereby changing the distance between the lowermost corner of the tripod and the film. This causes the lowermost corner of the tripod to move up and down, which in turn drives the lower pressure rod to swing up and down around its connection with the inner wall of the laminator through the first transmission rod. The swinging of the lower pressure rod will drive the slitting blade to swing up and down. The swinging slitting blade will regularly press and cut the moving film, thereby achieving the slitting of the film.

[0022] 4. The diameter of the drive gear is much larger than that of the transmission gear. The large gear drives the small gear, which is a force-saving structure. At the same time, with the uppermost corner of the tripod as the axis, according to the lever principle, the transmission gear drives the lowermost corner of the tripod to move up and down, which is also a force-saving structure. Furthermore, with the connection between the lower pressure rod and the inner wall of the laminator as the axis, according to the lever principle, the first transmission rod drives the slitting blade to swing up and down, which is also a force-saving structure. Therefore, the first motor only needs to transmit less kinetic energy to achieve the slitting of the film. This structure achieves the slitting of the film through a force-saving mechanical structure, reducing production costs. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] Example 1, please refer to the accompanying drawings in the specification. Figures 1-7 A precise screen protector application device includes a screen protector application machine 1, a film slitting component 2, and a screen conveying component 3. The film slitting component 2, capable of uniformly cutting the film, is installed inside the screen protector application machine 1. The screen conveying component 3, capable of uniformly transporting the screen of a mobile phone to be covered, is also installed inside the screen protector application machine 1. The film slitting component 2 is located above the screen conveying component 3. The film slitting component 2 and the screen conveying component 3 are not directly connected. The film slitting component 2 includes a linkage slitting component 4 and a film feeding component 5. Both the linkage slitting component 4 and the film feeding component 5 are connected to the inner wall of the screen protector application machine 1 and are driven together. The linkage slitting component 4 is located in front of the film feeding component 5, and the film feeding component 5 is closer to a take-up roller located at the rear of the screen protector application machine 1.

[0035] Based on Embodiment 1, the film feeding assembly 5 includes a drive gear 6, an upper roller 7, a first motor 8, and a lower roller 9. The upper roller 7 and the lower roller 9 are rotatably disposed inside the laminating machine 1, and there is a gap between the upper roller 7 and the lower roller 9. One end of the upper roller 7 is fixed with the drive gear 6, which is located inside the laminating machine 1. The other end of the upper roller 7 is fixedly connected to the output end of the first motor 8, which is located outside the laminating machine 1 and is fixed to the outer surface of the laminating machine 1. Rubber sleeves are fixed to the outer surfaces of both the upper roller 7 and the lower roller 9, and the upper roller 7 and the lower roller 9 will squeeze the film.

[0036] The linkage slitting assembly 4 includes a tripod 10, a first transmission rod 11, a lowering rod 12, a slitting blade 13, a second transmission rod 14, a third transmission rod 15, and a transmission gear 16. The tripod 10, the lowering rod 12, and the transmission gear 16 are rotatably mounted on the inner wall surface of the laminator 1. The third transmission rod 15 is fixedly mounted on the side surface of the transmission gear 16. The second transmission rod 14 is rotatably connected to the ends of the tripod 10 and the third transmission rod 15. The first transmission rod 11 is rotatably connected to the ends of the tripod 10 and the lowering rod 12. The slitting blade 13 is fixed to the end surface of the lowering rod 12. Since the slitting blade 13 is fixedly connected to the lowering rod 12, and the running trajectory of the lowering rod 12 is fixed, the orientation of the slitting blade 13 when it contacts the film each time it moves down remains unchanged.

[0037] The tripod 10 is a right triangle. The second transmission rod 14 is rotatably connected to the 30-degree end of the tripod 10. The right-angle end of the tripod 10 is rotatably connected to the inner wall of the film applicator 1. The first transmission rod 11 is rotatably connected to the 60-degree end of the tripod 10. The drive gear 6 and the transmission gear 16 are corresponding and meshing. The diameter of the drive gear 6 is larger than the diameter of the transmission gear 16.

[0038] The screen conveying assembly 3 includes a belt conveyor 17, a positioning plate 18, a worm gear 19, a worm wheel 20, a second motor 21, a movable plate 22, and a rectangular plate 23. The belt conveyor 17 is fixedly installed on the bottom surface inside the film applicator 1. The worm wheel 20 is rotatably located on the upper surface inside the film applicator 1. The worm gear 19 is rotatably located inside the film applicator 1, and the worm wheel 20 and the worm gear 19 are meshed together. The second motor 21 is fixed on the outer surface of the film applicator 1, and the output end of the second motor 21 is fixedly connected to the end of the worm gear 19. The rectangular plate 23 is fixed on the lower surface of the worm wheel 20. One end of the movable plate 22 is rotatably connected to the end of the rectangular plate 23, and the other end of the movable plate 22 is rotatably connected to the upper surface of the positioning plate 18. The positioning plate 18 is slidably located on the upper surface of the belt conveyor 17. The worm wheel 20 is located above the middle position of the belt conveyor 17. Multiple sets of rollers are rotatably installed inside the positioning plate 18.

[0039] In actual use, the mobile phone screen to be covered is placed on the belt conveyor 17, and the second motor 21 is started to drive the worm gear 19 to rotate. The rotation of the worm gear 19 will drive the worm wheel 20 to rotate, and the rotation of the worm wheel 20 will drive the rectangular plate 23 to rotate. Since the rectangular plate 23 is relatively long, the rotation of the rectangular plate 23 will pull the positioning plate 18 through the movable plate 22, so that the two sets of symmetrical positioning plates 18 move towards each other. Since the guide rod fixed inside the belt conveyor 17 is slidably connected to the protrusion fixed at the upper end of the positioning plate 18, the positioning plate 18 will not shift when it moves until the side surfaces of the two sets of positioning plates 18 contact the side surfaces of the mobile phone screen. At this time, the positioning plate 18 plays a positioning role for the mobile phone screen, avoiding the shifting of the mobile phone screen when the belt conveyor 17 is transporting it.

[0040] Meanwhile, the positioning plate 18 does not directly contact the mobile phone screen. Instead, the mobile phone screen is contacted by a roller that is rotatably installed inside the positioning plate 18. Therefore, the connection between the mobile phone screen and the positioning plate 18 is not a sliding connection but a rolling connection, which greatly reduces the friction between the mobile phone screen and the positioning plate 18 and avoids affecting the conveyor belt 17's transport of the mobile phone screen due to excessive friction.

[0041] When the film is slit, the first motor 8 is started to drive the upper roller 7 to rotate. Since the film is located between the upper roller 7 and the lower roller 9, and the outer surfaces of the upper roller 7 and the lower roller 9 are fixed with rubber sleeves, the friction between the upper roller 7 and the lower roller 9 and the film increases. Therefore, when the upper roller 7 rotates, it pulls the film, causing the film to move towards the linkage slit assembly 4. The rotation of the upper roller 7 drives the drive gear 6 to rotate, which in turn drives the transmission gear 16 to rotate. The rotation of the transmission gear 16 drives the third transmission rod 15 to rotate, and the rotation of the third transmission rod 15 pulls the second transmission rod 14. The movement of the second transmission rod 14 pulls the tripod 10 through its connection with the tripod 10, causing the uppermost corner of the tripod 10 to rotate slightly on the inner wall of the laminator 1. This changes the distance between the lowermost corner of the tripod 10 and the film, causing the lowermost corner of the tripod 10 to move up and down. This movement, in turn, drives the lower pressure rod 12 to swing up and down around its connection with the inner wall of the laminator 1 via the first transmission rod 11. The end of the lower pressure rod 12 swings up and down, which in turn drives the slitting blade 13 to swing up and down. The slitting blade 13 swings up and down, which in turn performs regular pressure cutting on the moving film, thereby achieving the cutting of the film.

[0042] The diameter of the drive gear 6 is much larger than that of the transmission gear 16. The large gear drives the small gear, which is a force-saving structure. At the same time, with the uppermost corner of the tripod 10 as the axis, according to the lever principle, the transmission gear 16 drives the lowermost corner of the tripod 10 to move up and down, which is also a force-saving structure. Furthermore, with the connection between the lower pressure rod 12 and the inner wall of the laminator 1 as the axis, according to the lever principle, the first transmission rod 11 drives the slitting blade 13 to swing up and down, which is also a force-saving structure. Therefore, the first motor 8 only needs to transmit less kinetic energy to achieve the slitting of the film. This structure achieves the slitting of the film through a force-saving mechanical structure, reducing production costs.

[0043] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
