Technical Field

[0001] The utility model belongs to the technical field of backlight module processing, and particularly relates to a backlight adhesive strip device for display module processing. Background Technique

[0002] In the process of producing a backlight backplane, it is necessary to attach an adhesive strip to the U-shaped folding plate of the product. This step is very important because the adhesive strip can help fix the position of the backplane and ensure the stability of the entire structure. When attaching the adhesive strip, it is necessary to pay attention to ensuring the uniformity and firmness of the adhesive strip to ensure that the backplane will not loosen or fall off during use.

[0003] However, in the prior art, most adhesive strips cannot accurately adjust their positions during adhesive application. It is necessary to repeatedly adjust and correct the position of the adhesive strip to achieve the desired effect, resulting in the adhesive strip not being able to fully adhere to the target surface, affecting the aesthetics and sealing performance of the final product, which brings a lot of inconvenience to use.
