When the material (television screen) passes through the primary pressing (some small bubbles may still remain and not be discharged), along with the continuous movement of the conveying belt to the driving roller and the driven roller, the driving roller contacts the screen surface under the driving of the lifting plate, and the driven roller is connected with the lifting plate through the elastic element. When contacting the screen, the driven roller will adaptively adjust the pressure between the screen according to the flatness of the screen surface and the actual situation of the primary pressing, relying on the telescopic characteristics of the elastic element (composed of a spring sleeve on a telescopic rod, which can provide stable elastic force and ensure the accurate telescopic direction) to perform secondary pressing on the screen. In this process, the residual bubbles are further squeezed out under the action of the secondary pressing force, thereby greatly reducing the generation of bubbles after film laminating, improving the completeness and quality of the film laminating, making the film laminating effect more ideal, and ensuring the appearance quality of the television screen and the stability of subsequent use.

[0021] 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.

[0022] Please see Figures 1-4 A television screen laminating device with a secondary pressing structure includes a worktable 1, a film frame 2, auxiliary rollers 3, and a pressing assembly. The worktable 1 is equipped with a conveyor belt. The film frames 2 are symmetrically arranged on the left and right sides of the worktable 1. The auxiliary rollers 3 are symmetrically arranged at the front and rear ends of the two sets of film frames 2. The pressing assembly includes a top plate 4, a lifter 5, a lifting plate 6, a drive roller 7, a driven roller 8, a roller frame 9, and an elastic element. The top plate 4 is arranged above the middle part of the two sets of film frames 2. The output end of the lifter 5 passes through the top plate 4 and is connected to the lifting plate 6. The drive roller 7 is arranged below the lifting plate 6 near the material inlet direction. The upper and lower ends of the elastic element are connected to the other end of the lifting plate 6 and the roller frame 9. The driven roller 8 is arranged below the roller frame 9.

[0023] Install the film material for lamination on the film holders 2 on both sides of the workbench 1, and pass the starting end of the film around the corresponding auxiliary rollers 3 in sequence so that the film can be laid flat above the conveyor belt. The width of the film should be able to completely cover the surface of the TV screen, and the TV screen conveyed on the conveyor belt is ready to be laminated.

[0024] Based on factors such as the thickness of the television screen to be coated and the characteristics of the coating material, the height of the lifting plate 6 is adjusted by controlling the extension and retraction of the lifting device 5 (hydraulic cylinder). This, in turn, drives the active roller 7 and the driven roller 8 to adjust to the appropriate initial height, ensuring that the active roller 7 and the driven roller 8 maintain an appropriate distance from the television screen and the film on the conveyor belt. This ensures accurate contact and pressing at the start of the coating process. During this process, the guide rod 13 plays a crucial guiding role, ensuring the smooth lifting of the lifting plate 6. Furthermore, the height of the lifting plate 6 can be further fine-tuned through observation and simple testing (such as manually rotating the conveyor belt to pass a screen sample under the pressing assembly to check if the relative positions of the rollers, screen, and film are appropriate), ensuring accurate initial positioning and laying the foundation for high-quality subsequent coating operations.

[0025] The conveyor belt is started, and it begins to move the TV screen along its conveying direction towards the lamination assembly. When the TV screen, carrying the film laid on top, moves to below the drive roller 7, the screen and film will first contact the drive roller 7, which is installed below the lifting plate 6 and is at a suitable height along with the lifting plate 6. The drive roller 7 then begins to rotate under the drive of the screen and film (relying on its own good rotational performance and the friction between it and the screen and film to achieve rotation), performing the initial pressing of the screen and film, so that the film is initially adhered to the screen surface. However, at this time, due to various factors (such as residual air between the film and the screen, minor unevenness in the film laying, etc.), some tiny air bubbles may still remain and not be completely expelled. After the initial pressing, the screen and film continue to move forward with the conveyor belt, preparing to enter the secondary pressing stage.

[0026] After the initial pressing, the TV screen and film continue to move below the driven roller 8. At this point, the driving roller 7 has already made contact with the screen and is continuously applying pressure for pressing. Under the push of the screen, the driven roller 8 begins to function through the structure connected to the lifting plate 6 via elastic elements (spring 10 and telescopic rod 11). Because the elastic elements are set in several evenly arranged groups, the roller frame 9 and the driven roller 8 can be evenly stressed. When the driven roller 8 contacts the screen, if there are uneven surfaces on the screen or air bubbles after the initial pressing, the driven roller 8 will adaptively adjust its distance and pressure from the screen based on the actual contact pressure and the expansion and contraction characteristics of the elastic elements.

[0027] In actual use, the elastic element is set to several groups evenly arranged. The elastic element includes a spring 10 and a telescopic rod 11. The spring 10 is sleeved on the telescopic rod 11. The upper and lower ends of the spring 10 and the telescopic rod 11 are respectively connected to the lifting plate 6 and the roller frame 9 to ensure the stable lifting and moving of the roller frame 9.

[0028] In this embodiment, support legs 12 are provided at the four corners of the workbench 1 to provide stable support for the workbench 1.

[0029] In actual use, the roller frame 9 is also equipped with a stud 14 that passes through the lifting plate 6, and a nut 15 is also provided on the stud 14. During the entire lamination process, if it is found that the pressing strength of the driven roller 8 needs to be adjusted (for example, when changing to a film of different material and thickness or processing a TV screen of different size and hardness), the operator can achieve this by turning the nut 15 on the stud 14 on the roller frame 9. When the nut 15 is loosened, the position of the roller frame 9 relative to the lifting plate 6 can be adjusted appropriately (moved up or down a certain distance), changing the initial extension and contraction state of the elastic element, thereby adjusting the initial pressure between the driven roller 8 and the screen; tightening the nut 15 plays a role in fixing and fine-tuning, ensuring that the position of the roller frame 9 and the driven roller 8 is stable during the lamination process, ensuring that the pressure of the secondary pressing meets the actual requirements, so that the lamination device can flexibly adapt to different lamination conditions, and improve the quality and adaptability of the lamination operation.
