Film attachment equipment for light guide plate

Abstract

The invention provides a film attachment device for a light guide plate, which includes a supporting mechanism, a sliding mechanism, a film attaching mechanism, a positioning sensing device and an attaching device controller. Install light guide plates of various specifications and sizes, the sliding mechanism is used to drive the film material attachment mechanism to move in the length and / or width direction of the side of the light guide plate, and the film material attachment mechanism is used to attach the film material to the length of the light guide plate And / or the film attachment surface in the width direction, wherein the attachment device controller can be programmed to automatically cut the film length of the light guide plate that meets various specifications and sizes, and then provide the precise attachment position through the positioning sensing device to place the film The film attachment surface is precisely attached to the side of the light guide plate.

Description

technical field [0001] The invention relates to the design of a film material attachment device, in particular to an automatic film material attachment device for a light guide plate. Background technique [0002] In the technical field of backlight modules, the role of the Light Guide Plate (Light Guide Plate) in its components is the light guiding medium. The cold cathode tube (CCFL) is converted into a surface light source and provided for the liquid crystal display panel. The light guide plate transmits the light from the light source to every corner of the entire light guide plate, and then uses the bottom surface of the light guide plate to print pattern diffusion points, and the reflected light will diffuse to all angles. Various reflection angles guide the light to the front of the light guide plate. The larger the refractive index, the better the light guiding ability. The light source sends light into the light guide plate from one side of the light guide plate, ...

AI Technical Summary

Problems solved by technology

The operator takes out the film material according to the model, tears the film material off the release paper manually, and then presses and attaches the film material to the corresponding position of the light guide plate with fingers. Attachment quality and attachment speed vary greatly, and long-term work is likely to cause finger skin and wrist injuries, resulting in high turnover of personnel and unstable output
