Method for pasting on side of light-leaking prevention paster of light guide plate

Abstract

The invention relates to a method for pasting on side of a light-leaking prevention paster of a light guide plate, which comprises the steps of fixing position, separating, cutting by contraposition, stitching and pasting, and flattening. The arrangement of a reference frame in a position-fixing step is used, which can be taken as the functions of paralleling and positioning the paste surface at the side edge of the light guide plate, the paster through the separating step is sent to the cutting by contraposition step, the paster position is corresponded to the starting point of the side edge of the light guide plate, and release paper is recovered, the paster after stitching and pasting is attached on the side edge of the light guide plate, and is carried out with the flattening step, the flatness of the paster is increased, and the side pasting work of the paster can be completed.

Description

technical field [0001] The invention relates to a side-attachment method of a light-guide plate anti-leakage sticker, in particular to a side-attachment step for a light guide plate. Background technique [0002] In the application of the light guide plate in the backlight module, after the light source is projected from the light incident surface of the light guide plate, the light will still leak from the side of the light guide plate. At present, in order to prevent light leakage, the industry usually attaches a light-shielding film to the light guide plate. Side end faces to prevent light leakage. [0003] In the film attachment process of traditional light guide plates, it is attached manually. However, the film is attached manually. In addition to the long steps and poor efficiency, the quality of the paste cannot be effectively controlled, which often leads to tightness. The reduction of the degree of fit will affect the effect of preventing light leakage. [0004] ...

AI Technical Summary

Problems solved by technology

[0003] In the film attachment process of traditional light guide plates, it is attached manually. However, the film is attached manually. In addition to the long steps and poor efficiency, the quality of the paste cannot be effectively controlled, which often leads to tightness. The reduction of fit will affect the effect of anti-light leakage

[0004] In order to solve the traditional pasting method and effect, the industry has developed automatic pasting with automatic equipment. Although this automatic pasting method can solve the problems of too long steps and low efficiency of the traditional manual pasting method, the narrow surface pasting and Vacuum adsorption positioning and other steps still have to be solved on the flatness of the film material and the flatness of the paste, so it is still not a better attachment method
