Description

Technical Field

[0001] This utility model relates to the field of backlight assembly machines, and in particular to a film-tearning structure for a backlight assembly machine. Background Technology

[0002] Backlight assembly machines are used to assemble backlight components into display devices such as LCD screens. They contain multiple functional modules and can efficiently and accurately complete the assembly process to ensure backlight effect and quality. The film-removing structure of the backlight assembly machine is used because it can improve production efficiency, operate automatically and continuously, and ensure film-removing quality. It avoids film tearing or residue with precise and stable film-removing force, protects the product surface, and accurately removes film without touching other parts. It can also reduce labor costs and labor intensity, improve production consistency and stability, avoid long hours of repetitive work by workers, and help improve yield and production repeatability.

[0003] Existing backlight assembly machines typically employ either a tape-adhesive or mechanical clamping mechanism for film removal. In the tape-adhesive type, a tape feeding mechanism delivers tape, ensuring it adheres fully to the backlight module's protective film. Subsequently, a tape traction mechanism, driven by a motor, uses the stronger adhesive force between the tape and the protective film (which is greater than the adhesion between the protective film and the backlight module) to tear off the protective film. The torn protective film is then neatly wound up by a winding mechanism. In the mechanical clamping type, a high-precision positioning mechanical clamp first positions itself at the edge of the protective film, then precisely adjusts the clamping force to hold the film edge. A robotic arm and other transmission mechanisms drive the clamp to adjust its speed and direction according to the material, tearing off the film. The torn protective film is then guided to a collection device for sorting and collection.

[0004] In the daily use of the film-tearing structure of the backlight assembly machine, the replacement process of the tape roller has revealed significant drawbacks. Whenever the tape roller needs to be replaced, the operator has to face a tedious and complicated operation. In the current design, it is not easy to remove the tape roller from the rotating shaft. It often requires the use of multiple tools and the unscrewing of multiple fasteners in a specific order. Moreover, due to the limited internal space of the equipment, the operating space is very cramped. The whole process consumes a lot of time and energy, greatly reducing work efficiency and seriously affecting the convenience of the film-tearing structure of the backlight assembly machine in actual use. It has become a major factor hindering the smooth progress of production. Utility Model Content

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.

[0032] Reference Figures 1-3 The present invention provides an embodiment of a film-tearing structure for a backlight assembly machine, comprising a fixed plate 1, a fixed rod 2 fixedly connected to one side of the fixed plate 1 for fixing a pushing component, a pushing component provided on one side of the fixed rod 2 for pushing the tape, a plurality of transport rollers 5 rotatably connected to one side of the fixed plate 1 for transporting the tape, a rotating shaft 6 rotatably connected to one side of the fixed plate 1 for rotating a tape roller 7, a tape roller 7 slidably connected to the outer wall of the rotating shaft 6 for loading the tape, a plurality of fixed components provided inside the rotating shaft 6 for fixing the tape roller 7, a plurality of pressure relief rollers 11 rotatably connected to one side of the fixed plate 1 for releasing pressure, and a collecting roller 12 rotatably connected to one side of the fixed plate 1 for collecting the protective film;

[0033] Each fixing component includes a fixing pin 8, a limiting plate 9, and a spring 10. The outer wall of each fixing pin 8 is slidably connected to the inside of the rotating shaft 6 for fixing the tape roller 7. The inner wall of each limiting plate 9 is fixedly connected to the outer wall of the fixing pin 8 to limit the movement range of the fixing pin 8. Each spring 10 is disposed inside the rotating shaft 6 to provide elastic force to the fixing pin 8. One end of each spring 10 is fixedly connected to the inside of the rotating shaft 6, and the other end of each spring 10 is fixedly connected to one end of the fixing pin 8. The pushing component includes a telescopic rod 3 and a push plate 4. One end of the telescopic rod 3 is fixedly connected to one side of the fixing rod 2 for pushing the push plate 4. One side of the push plate 4 is fixedly connected to the output end of the telescopic rod 3 for pushing the tape. One side of the push plate 4 is slidably connected to the inside of the fixing plate 1.

[0034] Specifically, when it is necessary to replace the tape roller 7, the operator first presses the fixing pin 8. The fixing pin 8 is slowly retracted into the rotating shaft 6 under the action of finger force, unlocking the tape roller 7 that was originally fixed. Then, the operator firmly holds the tape roller 7 with both hands and pulls it horizontally off the rotating shaft 6. Then, the operator picks up the new tape roller 7, aligns it with the axis of the rotating shaft 6, and slowly slides it on. As the tape roller 7 slowly moves along the rotating shaft 6 until it reaches the bottom of the rotating shaft 6, the spring 10 installed below the fixing pin 8 pushes the fixing pin 8 to pop out quickly, blocking one side of the tape roller 7 and fixing the tape roller 7. At this point, the replacement of the tape roller 7 is completed.

[0035] Reference Figure 4 A connecting plate 13 is fixedly connected to one side of the fixing plate 1 for connecting the carrying plate 14. The carrying plate 14 is fixedly connected to one side of the connecting plate 13 for loading the fixing strip 16 and the fixing strip 19. Multiple sliding blocks 15 are slidably connected inside the carrying plate 14 for connecting the fixing strip 16. Each sliding block 15 has a fixing strip 16 fixedly connected to one side for fixing the glass plate. A spring 17 is provided inside the carrying plate 14 to provide elastic force for the movement of the fixing strip 16. One end of the spring 17 is fixedly connected to the bottom of one of the sliding blocks 15, and the other end of the spring 17 is fixedly connected to another sliding block 15. 5. At the top, multiple sliding blocks 18 are slidably connected inside the carrying plate 14 for connecting fixing strips 19. Each sliding block 18 is fixedly connected to one side of a fixing strip 19 for fixing the glass plate. A spring 20 is provided inside the carrying plate 14 to provide elastic force for the movement of the fixing strips 19. One end of the spring 20 is fixedly connected to the bottom of one of the sliding blocks 18, and the other end of the spring 20 is fixedly connected to the top of another sliding block 18. Fixing strips 16 are arranged in a symmetrical array and slidably connected to one side of the carrying plate 14. Sliding blocks 15 are arranged in a symmetrical array and slidably connected inside the carrying plate 14.

[0036] Specifically, when fixing the glass plate to be peeled, the operator first picks up the glass plate. Then, based on the length of one side of the glass plate, the operator adjusts the distance between fixing strip 16 and fixing strip 29 to ensure that the distance between fixing strips 16 and 29 is consistent with the length of the corresponding side of the glass plate. Next, the operator places the glass plate horizontally on the carrier plate 14, keeping the glass plate stable during placement. At this moment, spring 27 installed between fixing strips 16 and spring 320 installed between fixing strips 29 instantly releases elastic potential energy to generate tension. Under the action of this tension, fixing strips 16 and 29 contract inward and fit tightly against both sides of the glass plate, fixing the glass plate to the carrier plate 14, providing a solid foundation for the subsequent peeling operation.

[0037] Working principle: During the film-peeling process of the backlight assembly machine, first pick up the glass plate to be peeled, then adjust the distance between the fixing strip 16 and the fixing strip 19 to make them the same as the length of one side of the glass plate. Then place the glass plate on the carrier plate 14. The fixing strip 16 and the fixing strip 19 retract inward under the pull of the spring 27 and the spring 30, thereby fixing the glass plate on the carrier plate 14. Then replace the tape roller 7. First press the fixing pin 8 to retract it into the rotating shaft 6, unlock the tape roller 7, then hold the tape roller 7 and pull it out. Then put the new tape roller 7 back onto the rotating shaft 6. When the tape roller 7 enters the bottom of the rotating shaft 6, the fixing pin 8 pops out under the elastic force of the spring 10 to fix the tape roller 7, thus completing the replacement of the tape roller 7. Then pass the tape through the transport roller 5, then through the pressure relief roller 11, and finally connect it to the collection roller 12. The equipment can then be started to begin peeling the film off the glass plate.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
