Technical Field

[0001] This utility model relates to the field of LED display production technology, specifically to an auxiliary coating device for LED display production. Background Technology

[0002] An LED display screen is an electronic display device that displays text, images, or video by controlling the on / off state of light-emitting diodes (LEDs). It consists of an array of multiple LED pixels, achieving full-color display through combinations of LEDs of different colors (such as red, green, and blue). During the production of LED displays, a coating process is typically used to coat the LED surface and improve display quality. This coating process involves applying a thin film to the product surface using specific techniques. This film provides protection, waterproofing, dustproofing, and enhanced visual effects. Coating prevents scratches and contamination during production and transportation, reduces waste caused by scratches and static electricity damage, ensures a smooth and even fit of the optical film, improves display quality, and enhances overall product quality.

[0003] In the prior art, when applying a film to an LED display screen using a film coating equipment, the stability of the LED display screen cannot be well guaranteed during the film coating process. This makes the LED display screen prone to displacement during the film coating process, which may result in bubbles, wrinkles, or poor adhesion of the film. As a result, the film coating effect and quality cannot be well guaranteed. Therefore, in order to solve the above problems, an auxiliary film coating equipment for LED display screen production is proposed. Utility Model Content

[0024] 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.

[0025] Please see Figure 1-5 One embodiment provided by this utility model:

[0026] The telescopic cylinder 15 and motor 23 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0027] An auxiliary coating device for LED display production includes a processing base 1. An electric slide rail 11 is provided on the surface of the processing base 1, and a processing table 12 is movably connected to the surface of the electric slide rail 11. A support platform 13 is fixedly connected to the upper surface of the processing base 1. A roller 14 is movably connected to the inner side of the support platform 13. A telescopic cylinder 15 is fixedly installed on the inner side of the support platform 13, and a connecting frame 16 is fixedly connected to the output end of the telescopic cylinder 15. A pressure roller 17 is movably connected to the inner side of the connecting frame 16. An anti-deviation mechanism is provided on the surface of the processing table 12, and an auxiliary mechanism is provided on the surface of the connecting frame 16. The anti-deviation mechanism includes a limit switch. Plate 27 and limiting plate 27 are set on the top of processing table 12. The auxiliary mechanism includes a first spring 3, which is fixedly connected to the upper surface of connecting frame 16. A connecting rod 33 is fixedly connected to the upper surface of connecting frame 16. The LED display screen can be placed by the setting of processing table 12. The film can be retracted and extended by setting roller 14. The extension of telescopic cylinder 15 causes connecting frame 16 to drive pressure roller 17 to descend, thereby enabling the film to be pressed onto the surface of LED display screen by pressure roller 17. With the movement of processing table 12 on electric slide rail 11, the LED display screen can be coated.

[0028] Furthermore, the anti-deviation mechanism also includes a connecting plate 2, which is fixedly connected to the surface of the processing table 12. A fixing block 21 is fixedly connected to the surface of the connecting plate 2. A positive and negative screw 22 is movably connected to the inner side of the fixing block 21. A motor 23 is fixedly installed on the surface of the fixing block 21. The output ends of the positive and negative screw 22 and the motor 23 are fixedly connected. By rotating the positive and negative screw 22, the moving block 24 can be moved, which facilitates the movement of the connecting block 25 and causes the limiting plate 27 to move, thereby achieving the effect of limiting the LED display screen by the limiting plate 27.

[0029] Furthermore, the surface of the positive and negative screws 22 is threaded with a movable block 24, and the surface of the movable block 24 is fixedly connected with a connecting block 25. The movable blocks 24 are movably connected to the positive and negative screws 22 in two groups, and the connecting blocks 25 are correspondingly connected to the movable blocks 24 in four groups. By setting the movable blocks 24, when the positive and negative screws 22 rotate, the movable blocks 24 can drive the connecting blocks 25 to move, thereby enabling the movable rod 26 to move and drive the limiting plate 27 to move. This facilitates the use of the limiting plate 27 to prevent the LED display screen from shifting, thus enabling stable film coating.

[0030] Furthermore, a movable rod 26 is movably connected to the surface of the connecting block 25. One end of the movable rod 26 is movably connected to the connecting block 25 via a pivot, and the other end of the movable rod 26 is movably connected to the limiting plate 27 via a pivot. By setting the movable rod 26, when the connecting block 25 moves, the movable rod 26 can move and push or pull the limiting plate 27, thereby facilitating the fixing of LED displays of different sizes through the limiting plate 27, making it less likely for the LED displays to shift during lamination, thus helping to ensure the lamination quality.

[0031] Furthermore, a limiting groove 28 is provided on the inner side of the connecting plate 2. The limiting groove 28 is provided in two sets on the inner side of the connecting plate 2, and the connecting block 25 moves within the limiting groove 28. By providing the limiting groove 28, the connecting block 25 can be limited, which can prevent the moving block 24 from causing the connecting block 25 to shift under the action of the positive and negative screws 22, so that the connecting block 25 can move stably, thereby ensuring that the moving rod 26 drives the limiting plate 27 to move.

[0032] Furthermore, the auxiliary mechanism also includes a fixed rod 31, which is fixedly connected to the bottom end of the support platform 13, and a connecting rod 33 is movable inside the fixed rod 31 and the support platform 13. A second spring 32 is fixedly connected to the inner wall of the fixed rod 31. One end of the second spring 32 is fixedly connected to the fixed rod 31, and the other end of the second spring 32 is fixedly connected to the connecting rod 33. Through the elastic properties of the first spring 3 and the second spring 32, when the pressure roller 17 is pressed down, the first spring 3 and the second spring 32 can absorb part of the impact force, which can prevent the pressure roller 17 from causing excessive instantaneous pressure on the LED display screen and can protect the LED display screen.

[0033] Furthermore, one end of the first spring 3 is fixedly connected to the connecting frame 16, and the other end of the first spring 3 is fixedly connected to the support platform 13. A slider 34 is fixedly connected to the surface of the connecting rod 33, and a groove 35 is provided on the inner wall of the fixed rod 31. The slider 34 moves inside the groove 35. Through the setting of the slider 34 and the opening of the groove 35, the connecting rod 33 can move stably inside the fixed rod 31. As a result, when the telescopic cylinder 15 extends and retracts to drive the connecting frame 16 to move up and down, it can be more stable, which makes it easier for the pressure roller 17 to press the film better.

[0034] Working principle: During use, the motor 23 is electrically connected to an external power source. The operator starts the motor 23 by pressing the switch. The motor 23 drives the positive and negative screws 22 to rotate. The connecting block 25 is limited by the limiting groove 28, which causes the moving block 24 to move under the action of the positive and negative screws 22. The connecting block 25 slides inside the limiting groove 28. Then the movable rod 26 moves through the rotating shaft and drives the limiting plate 27 to move accordingly. The movement of the limiting plate 27 limits the two sides of the LED display screen on the processing table 12, thereby preventing it from shifting during the lamination process.

[0035] When the telescopic cylinder 15 extends, causing the connecting frame 16 to drive the pressure roller 17 downward, the connecting rod 33 can guide the connecting frame 16, ensuring that the connecting frame 16 and the pressure roller 17 move vertically and stably under the action of the telescopic cylinder 15. At the same time, the connecting rod 33 will move inside the fixed rod 31. The pressure roller 17 is squeezed, causing the first spring 3 and the second spring 32 to deform. The first spring 3 and the second spring 32 can alleviate the downward force of the pressure roller 17 to a certain extent, thereby avoiding damage to the LED display screen due to excessive instantaneous pressure.

[0036] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
