A fully automatic backlight laminating machine

Abstract

This application relates to a full-automatic backlight lamination machine, including a brightness enhancement film conveyor belt used to transport the brightness enhancement film, a diffusion film conveyor belt used to transport the diffusion film, and a diffusion film conveyor belt located near the brightness enhancement film conveyor belt and the diffusion film conveyor belt. The lamination table for placing the bottom plate, the static electricity removal device installed on the lamination table to remove static electricity from the brightness enhancement film and the diffusion film, the dust removal device installed on the lamination table to remove dust from the brightness enhancement film and the diffusion film, and installed on the lamination film The moving rod above the stage, the diffusion film adsorption device arranged at the end of the moving rod and used to absorb the diffusion film, the brightness enhancement film adsorption device arranged at the end of the moving rod away from the diffusion film adsorption device and adsorbing the brightness enhancement film, and the film lamination table The table rod, the rod moving mechanism which is set on the table rod and drives the moving rod to move along the same linear direction where the diffusion film conveyor belt, the enhancement film conveyor belt, and the lamination table are located, is set at both ends of the moving rod and can be abutted The limit rod on the pole has the effect of reducing the possible impact on the quality of the assembled product.

Description

technical field [0001] The present application relates to the technical field of backlight assembly equipment, in particular to a fully automatic backlight laminating machine. Background technique [0002] The backlight is the main light-emitting part of the LCD (liquid crystal display), and the luminous performance of the backlight will directly affect the imaging quality of the LCD. Therefore, there are strict requirements in the assembly process of high-quality backlight. The assembly of the backlight generally requires the installation of lamp tube shields on both sides of the bottom plate, LED lamps are installed inside the lamp tube shields, and then the reflective paper, light guide plate, diffusion film, and enhancement film are laminated and installed on the bottom plate, so that the LED The emitted point light is finally converted into an area light. [0003] In the existing backlight assembly process, the process of sequentially laminating the die-cut diffusion f...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that it is easy to be difficult to align during the manual lamination process of the diffusion film and the brightness enhancement film, which makes the finally assembled backlight prone to light leakage, and there are defects that affect the quality of the assembled product.
