Processing protective device for light guide plate

Abstract

The invention discloses a processing protective device for a light guide plate. The processing protective device comprises a fixed bracket, an air cylinder set, a left positioning plate, a right positioning plate, an upper baffle plate, a lower baffle plate and a pressure plate, wherein the left positioning plate and the right positioning plate are regulated by an air cylinder to adapt to light guide plates with different dimensions for fixing and positioning the plurality of the light guide plates in a left-right direction; the plurality of the light guide plates are fixed and positioned in an up-down direction by virtue of the upper baffle plate, the lower baffle plate and the air cylinder; during polishing processing, the light guide plate can be prevented from being damaged by pressing, and side edges and four corners of the light guide plate are prevented from turned-down edge and turned-down corner phenomena, so that a to-be-processed light guide plate is effectively protected, production yield and processing quality of the light guide plate are improved, and the production cost is reduced. The processing protective device is simple in structure, convenient in operation, high in degree of automation, and capable of adapting to light guide plates with different specifications.

Description

Technical field: [0001] The invention belongs to the technical field of light guide plate processing equipment, and in particular relates to a light guide plate processing protection device. Background technique: [0002] With the development of the liquid crystal industry, the light guide plate has been widely used and has become an indispensable part of the liquid crystal module. The main function of the light guide plate is: after the LED light source is introduced from the side, it will be reflected by the printing dots in the later stage to make the light source uniform. During the processing of the light guide plate, the light guide plate needs to be cut. After cutting, the side surfaces of the light guide plate are rough and need to be polished to achieve a high surface finish and reduce the loss of light transmission. Therefore, in the process of processing, the side polishing treatment of the light guide plate is very important, which affects the quality of the lig...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is that when the light guide plate polishing machine in the prior art polishes the light guide plate, the uppermost light guide plate and the lowermost light guide plate are easily crushed, and the edges and four corners of the light guide plate are easily damaged. The phenomenon of edge collapse and collapse angle appears, the production output is low, the production cost is high, and the processing quality is low, which affects the processing and protection device of the light guide plate.
