Description

Technical Field

[0001] The utility model relates to the technical field of film sealing devices, in particular to a film sealing device for the surface of a display screen module. Background Art

[0002] The display screen module is a modular system composed of multiple components, including displays, drive circuits, backlight sources, touch screens, etc. They are assembled together to form a complete display screen for displaying images, videos, text and other content. Display screen modules are usually composed of display screen manufacturers, circuit board manufacturers and backlight manufacturers. During the production process of the display screen module, its surface needs to be sealed with a film to protect it from dust and water, so a sealing device is required.

[0003] When sealing the display screen module, after the film is cut, the end of the rolled film will droop and curl. When sealing the next display screen module, the film needs to be manually re-attached to the surface of the display screen module, which affects the efficiency of film sealing. In addition, during the film sealing process, the film is prone to skew and misalignment, which affects the quality of film sealing. Utility Model Content
