Description

Technical Field

[0001] This utility model relates to the field of backlight technology, and in particular to a backlight molding fixture. Background Technology

[0002] During the production of backlights, in order to ensure that each backlight film is tightly bonded together, a pressure-pressing rod is usually used for manual molding. However, as backlight products have developed, their bezels have become narrower and narrower, making it difficult to accurately position them when using a pressure-pressing rod for molding.

[0003] A search revealed that prior art CN206317504U discloses a backlight molding fixture, including a base, a positioning block fixed on the base, and a first groove matching the shape of the backlight on the positioning block; a second groove corresponding to the light-shielding adhesive on the backlight is provided on the side wall of the first groove; it also includes a pressing block matching the shape of the backlight and an aerodynamic source for driving the pressing block; during production, after the backlight is placed in the first groove on the positioning block, the pressing block is driven downward to press the backlight by the aerodynamic source, and the light-shielding adhesive can be compacted through the gap of the second groove, resulting in accurate positioning, high production efficiency, and high product yield; the overall structure is simple and the cost is low.

[0004] When using the aforementioned fixture, the applicant discovered that after the backlight processing was completed, the finished backlight needed to be removed and then the backlight to be processed was placed again for further processing. This method resulted in low processing efficiency during mass production. Utility Model Content
