Description

Technical Field

[0001] This utility model relates to the field of display screen coating technology, and in particular to a display screen glass panel coating machine. Background Technology

[0002] The monitor glass panel refers to the protective glass layer on the outside of the monitor screen. Its main function is to protect the internal LCD screen from external impacts or scratches. During the monitor manufacturing process, the monitor glass panel needs to be coated, so a display glass panel coating machine is required.

[0003] The existing patent publication number CN221212747U discloses a screen coating device. This utility model facilitates the pre-cleaning of the screen coating surface and can also clean the surface of the screen film layer after coating, preventing dust from adhering to the screen coating surface and affecting the coating effect, which is beneficial to improving the coating yield of the screen.

[0004] However, the display glass panel laminating machine disclosed in the above patent cannot perform limited conveying of display screen parts of different sizes during use, which has significant limitations. Therefore, we propose a display glass panel laminating machine to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a display screen glass panel laminating machine that can solve the problem that existing display screen glass panel laminating machines cannot perform limited conveying of display screen parts of different sizes, which has significant limitations.

[0007] To solve the above technical problems, this utility model provides a display screen glass panel laminating machine, which adopts the following technical solution: it includes a processing frame, with support seats fixedly installed at both ends of the bottom of the processing frame, a conveyor belt for conveying display screen processing parts rotatably installed on the processing frame, and a laminating machine body for laminating the display screen processing parts fixedly installed in the middle of the top of the processing frame, and two sets of limiting components are provided on the processing frame, the two sets of limiting components being symmetrically arranged about the center line of the processing frame;

[0008] The limiting assembly includes two hydraulic cylinders, which are respectively fixedly installed at both ends of the top of the processing frame. A lifting plate is fixedly connected between the telescopic ends of the two hydraulic cylinders. A movable groove is fixedly opened inside the lifting plate. A bidirectional lead screw is rotatably installed inside the movable groove. A motor is fixedly installed at the end of the lifting plate. The drive end of the motor extends movably into the movable groove and is fixedly connected to the bidirectional lead screw. Two movable plates are threadedly connected to the outer ring of the bidirectional lead screw. The ends of the movable plates are adapted to the movable groove. A connecting plate is fixedly installed at the bottom of the movable plate. Several mounting brackets are arranged at equal intervals on the side of the connecting plate. Rollers are rotatably installed on the mounting brackets. The rollers are in contact with the side wall of the display screen processing part.

[0009] Preferably, the mounting bracket includes a sleeve rod, which is fixedly disposed on the side of the connecting plate. A slide rod is slidably disposed inside the sleeve rod. A spring is fixedly connected between the slide rod and the inner wall of the sleeve rod. A fixing plate is fixedly disposed at the lower end of the side of the slide rod. A fixing shaft is fixedly disposed at the top of the end of the fixing plate. A roller is rotatably disposed at the outer ring of the fixing shaft.

[0010] Preferably, a rotating plate is rotatably provided on the upper end of the side of the slide rod, an elastic insert is fixedly provided on the lower surface of the rotating plate, a slot is fixedly provided on the upper end of the fixed shaft, the elastic insert and the slot are adapted to each other, and a pull ring is fixedly provided on the upper surface of the rotating plate.

[0011] Preferably, a vacuum cleaner is fixedly installed on the top of the lifting plate located in front of the conveying direction of the display screen processing parts. The air inlet of the vacuum cleaner is connected to an exhaust pipe. Two first L-shaped rods are fixedly installed on the side of the lifting plate. A flow guide is fixedly connected between the lower ends of the two first L-shaped rods. Several suction nozzles are fixedly installed at equal intervals at the bottom of the flow guide. A flow collection chamber is provided inside the flow guide. The flow collection chamber, the exhaust pipe and the suction nozzles are interconnected.

[0012] Preferably, two second L-shaped rods are fixedly installed on the side of the lifting plate away from the first L-shaped rod, and an installation plate is fixedly connected between the lower ends of the two second L-shaped rods. A wiping plate is detachably installed at the bottom of the installation plate, and the wiping plate and the upper surface of the display screen processing part are in contact with each other.

[0013] Preferably, the wiping plate is located in front of the suction nozzle.

[0014] Preferably, a wear-resistant layer is fixedly provided on the outer ring of the roller.

[0015] In summary, this utility model has at least one of the following beneficial effects:

[0016] 1. By installing the limiting component, when the size of the display screen parts is different, the motor is started, which drives the bidirectional lead screw to rotate, thereby causing the two movable plates to move away from or towards each other, and in turn causing the rollers on both sides to move away from or towards each other. This enables the limiting conveying of display screen parts of different sizes, solving the problem that the existing display screen glass panel laminating machine cannot limit the conveying of display screen parts of different sizes, which has a great limitation.

[0017] 2. The spring design provides a buffer space between the roller and the display screen component, preventing hard contact that could damage the side of the component. When the roller is damaged, pulling the pull ring causes the rotating plate to rotate around the slide bar, which pulls the elastic rod out of the slot. Then, the roller is removed from the fixed shaft. After replacing the roller, the process can be reversed, improving the efficiency of roller replacement.

[0018] 3. The dust on the display screen parts is initially cleaned by wiping the plate to reduce the amount of dust and loosen it. Then, the dust is completely absorbed by the vacuum nozzle to improve the dust removal effect on the display screen parts. This prevents dust from adhering to the coated surface of the display screen parts and affecting the coating treatment effect, which is conducive to improving the coating yield of the display screen parts.

[0019] 4. When the thickness of the display screen parts is different, the hydraulic cylinder is activated to move the lifting plate up and down, which in turn moves the rollers, dust nozzles and wiping plates up and down in sync, thereby adapting to display screen parts of different thicknesses and improving the applicability of the device.

[0027] 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.

[0028] Please see Figure 1-5 This utility model provides an embodiment of a display screen glass panel laminating machine, including a processing frame 1. Support seats 3 are fixedly installed at both ends of the bottom of the processing frame 1. A conveyor belt 2 for transporting display screen parts is rotatably mounted on the processing frame 1. A laminating machine body 4 for laminating the display screen parts is fixedly installed at the center of the top of the processing frame 1. When using this utility model, the display screen parts are placed on the conveyor belt 2, and the conveyor belt 2 transports the display screen parts to the laminating machine body 4, where the laminating machine body 4 performs the laminating operation. To limit the transport of the display screen parts and ensure that they are transported at the exact center of the conveyor belt 2, two sets of limiting components are installed on the processing frame 1. The two sets of limiting components are symmetrically arranged about the center line of the processing frame 1. By installing the limiting components, the two sides of the display screen parts are limited, ensuring that the display screen parts are at the exact center of the conveyor belt 2, thereby avoiding the problem of incomplete lamination and low lamination quality caused by deviation.

[0029] Furthermore, the limiting component includes two hydraulic cylinders 5, which are respectively fixedly installed at both ends of the top of the processing frame 1. A lifting plate 6 is fixedly connected between the telescopic ends of the two hydraulic cylinders 5. A movable groove is fixedly opened inside the lifting plate 6. A bidirectional lead screw 7 is rotatably installed inside the movable groove. A motor 8 is fixedly installed at the end of the lifting plate 6. The driving end of the motor 8 extends into the movable groove and is fixedly connected to the bidirectional lead screw 7. Two movable plates 9 are threadedly connected to the outer ring of the bidirectional lead screw 7. The ends of the movable plates 9 are adapted to the movable groove. A connecting plate 10 is fixedly installed at the bottom of the movable plate 9. Several mounting brackets are arranged at equal intervals on the side of the connecting plate 10. Rollers 16 are rotatably installed on the mounting brackets. The rollers 16 and the side wall of the display screen processing part are in contact with each other.

[0030] While limiting the movement of the display screen processing parts by using rollers 16 on both sides, the rollers 16 can also rotate on their own, thus preventing them from obstructing the conveying of the display screen processing parts on the conveyor belt 2. When the size of the display screen processing parts is different, the motor 8 is started, which drives the bidirectional lead screw 7 to rotate, thereby causing the two movable plates 9 to move away from or towards each other, and in turn causing the rollers 16 on both sides to move away from or towards each other. This allows for the limiting and conveying of display screen processing parts of different sizes, solving the problem that existing display screen glass panel laminating machines cannot limit and convey display screen processing parts of different sizes, which has significant limitations.

[0031] Furthermore, the mounting bracket includes a sleeve rod 11, which is fixedly mounted on the side of the connecting plate 10. A slide rod 12 is slidably mounted inside the sleeve rod 11. A spring 13 is fixedly connected between the slide rod 12 and the inner wall of the sleeve rod 11. A fixing plate 14 is fixedly mounted on the lower end of the side of the slide rod 12. A fixing shaft 15 is fixedly mounted on the top of the end of the fixing plate 14. A roller 16 is rotatably mounted on the outer ring of the fixing shaft 15. A rotating plate 17 is rotatably mounted on the upper end of the side of the slide rod 12. An elastic insert rod 18 is fixedly mounted on the lower surface of the rotating plate 17. A slot is fixedly mounted on the upper end of the fixing shaft 15. The elastic insert rod 18 is adapted to the slot. A pull ring 19 is fixedly mounted on the upper surface of the rotating plate 17.

[0032] The spring 13 provides a buffer space between the roller 16 and the display screen component, preventing hard contact between the roller 16 and the display screen component and thus avoiding damage to the side of the display screen component.

[0033] Since roller 16 is a consumable item, a wear-resistant layer is fixedly installed on the outer ring of roller 16 to improve the wear resistance of roller 16 and extend the service life of roller 16.

[0034] In addition, when the roller 16 is damaged, pull the pull ring 19 to drive the rotating plate 17 to rotate around the slide bar 12, thereby pulling the elastic insert 18 out of the slot, and then removing the roller 16 from the fixed shaft 15. After replacing it with a new roller 16, the operation can be reversed, which improves the efficiency of replacing the roller 16.

[0035] Considering that dust adhering to the glass panel coating surface on the display screen processing parts affects the coating treatment effect, a vacuum cleaner 20 is fixedly installed on the top of the lifting plate 6 located in front of the display screen processing parts in the conveying direction. The air inlet end of the vacuum cleaner 20 is connected to the suction pipe 23. Two first L-shaped rods 21 are fixedly installed on the side of the lifting plate 6. A flow guide hood 22 is fixedly connected between the lower ends of the two first L-shaped rods 21. Several dust suction nozzles 24 are fixedly installed at equal intervals at the bottom of the flow guide hood 22. A flow collection chamber is provided inside the flow guide hood 22. The flow collection chamber, the suction pipe 23 and the dust suction nozzles 24 are interconnected.

[0036] After the vacuum cleaner 20 is started, the dust on the display screen parts is sequentially drawn into the suction nozzle 24, the collection chamber, and the extraction pipe 23 to remove the dust from the display screen parts. In addition, two second L-shaped rods 25 are fixedly installed on the side of the lifting plate 6 away from the first L-shaped rod 21. A mounting plate 26 is fixedly connected between the lower ends of the two second L-shaped rods 25. A wiping plate 27 is detachably installed at the bottom of the mounting plate 26. The wiping plate 27 is in contact with the upper surface of the display screen parts. The wiping plate 27 is located in front of the suction nozzle 24. The wiping plate 27 is used to initially clean the dust on the display screen parts, reduce the amount of dust and loosen it, so that the suction nozzle 24 can completely absorb it, thereby improving the dust removal effect on the display screen parts.

[0037] When the thickness of the display screen parts varies, the hydraulic cylinder 5 is activated, which drives the lifting plate 6 to move up and down, thereby synchronously driving the roller 16, the dust suction nozzle 24 and the wiping plate 27 to move up and down, thus adapting to display screen parts of different thicknesses and expanding the applicability of the device.

[0038] Working principle: When using this utility model, the display screen processing parts are placed on the conveyor belt 2, the motor 8 is started, and the bidirectional lead screw 7 is rotated, which in turn causes the two movable plates 9 to move away from or closer to each other, which in turn causes the rollers 16 on both sides to move closer to each other. This allows for the limited conveying of display screen processing parts of different sizes and ensures that they are conveyed in the center position of the conveyor belt 2, preventing them from shifting position. Finally, the display screen processing parts are conveyed to the laminating machine 4 via the conveyor belt 2, where the laminating machine 4 performs the laminating operation. In addition, when the display screen processing parts are placed on the conveyor belt 2, the dust on the display screen processing parts is initially cleaned by the wiping plate 27 to reduce the amount of dust and loosen it. After the vacuum cleaner 20 is started, the dust on the display screen processing parts is sequentially drawn into the vacuum nozzle 24, the collection chamber and the air extraction pipe 23, thereby thoroughly removing the dust on the display screen processing parts and preventing dust from adhering to the laminating surface of the display screen processing parts and affecting the laminating effect.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
