Description

Technical Field

[0001] The utility model relates to the technical field of backlight source processing, in particular to a film sticking device for a backlight source module. Background Art

[0002] The backlight is a light source located behind the LCD display. Its luminous effect will directly affect the visual effect of the LCD display module. The LCD display itself does not emit light. It displays graphics or the result of its light modulation. Before the backlight is used, its surface needs to be treated with a film.

[0003] For example, a backlight film pasting device (Announcement No.: CN216485853U) includes an operating table and a control switch arranged at the front end of the operating table. The mounting frame is installed on the upper end of the operating table through a support rod. The inner wall of the mounting frame is provided with a side groove. The cylinder is installed on the inner wall of the side groove, and the other end is connected to the linkage block. A mounting plate is provided on one side of the linkage block. There are two groups of mounting plates, and a roller is movably installed in the middle of the two groups of mounting plates. The outer wall of the roller is sleeved with an external cylinder, and the external cylinder is a component made of rubber material. The bottom end of the external cylinder is at the same height as the backlight structure. The operator can use the switch to make the cylinder push the linkage block to move forward and backward. At this time, the roller can move with the external cylinder, so that the backlight structure and the protective film can be pressed, which is convenient for film pasting and can drive away bubbles at the same time, with good use effect.

[0004] When the device is in use, the roller and the external cylinder are directly used to press the backlight structure and the protective film, which may damage the backlight module and easily affect the quality of the backlight module after the film is applied. Therefore, we need to propose a film application device for the backlight module. Utility Model Content
