Description

Technical Field

[0001] The utility model relates to a lamination device for a liquid crystal display screen. Background Technique

[0002] From the perspective of the screen structure, we can roughly divide the screen into three parts, namely the protective glass, the touch screen, and the display screen. During the production process of the liquid crystal display screen, these three parts need to be laminated. Currently, the main lamination technology for liquid crystal display screens is full lamination, which means using water glue or optical glue to completely bond the panel and the touch screen together in a seamless manner. Generally, two laminations are required, one between the protective glass and the touch screen, and the other between the display screen and the touch screen.

[0003] Ensuring the accuracy of the position of the display screen during the lamination process is crucial for improving the lamination quality. Traditional lamination devices may have some defects, such as being unable to effectively limit the position of the display screen, resulting in deviation of the position of the display screen during the lamination process and affecting the final lamination effect. In addition, when the existing devices perform positioning processing on display screens of different widths, they may lack sufficient adaptability and flexibility, restricting their application in diverse production requirements. In view of this, the utility model proposes a lamination device for a liquid crystal display screen to solve the above problems. Summary of the Utility Model

Two symmetrically arranged positioning through grooves 55 are opened on the positioning plate 51. Two limiting plates 52 are arranged on the two positioning through grooves 55. The two limiting plates 52 are symmetrically arranged. Two elastic support assemblies 60 are also symmetrically arranged on the positioning plate 51. The two elastic support assemblies 60 are respectively connected to the two limiting plates 52, so that the two limiting plates 52 are displaced towards the center direction of the positioning plate 51.

[0036] In this embodiment, when performing a pressing process on a liquid crystal display screen, the liquid crystal display screen is placed on the positioning plate 51. Then, the two limiting plates 52 are displaced towards the center direction of the positioning plate 51 through the elastic support assemblies 60, so that the limiting plates 52 clamp the liquid crystal display screen on the positioning plate 51. Then, the pressing assembly 30 descends until the pressing assembly 30 contacts the liquid crystal display screen, thereby completing the pressing process;

[0037] Through the above setting of the two limiting plates 52 that are displaced towards the center direction of the positioning plate 51, the liquid crystal display screen can be effectively limited, ensuring the accurate position of the display screen during the pressing process, thereby improving the pressing quality. At the same time, it ensures that the liquid crystal display screen can be accurately placed at a predetermined position before pressing, avoiding affecting the pressing effect due to deviations during the pressing process, greatly improving the overall practicality, and also facilitating the positioning of liquid crystal display screens with different widths, with high applicability.

[0038] Specifically, the positioning through groove 55 is provided with a positioning portion 552 and a sliding portion 551;
