LED display backlight source manufacturing process

Abstract

The invention provides an LED display backlight source manufacturing process. The LED display backlight source manufacturing process adopts an LED displayer backlight source manufacturing device. The LED display backlight source manufacturing device comprises a machine frame, a fixing unit and a polishing unit, a fixing groove is formed in the machine frame, the fixing unit is arranged in the fixing groove, and the polishing unit is mounted on the inner side wall of the machine frame. The problems that most of existing light guide plate manufacturing devices adopt alloy devices to limit and fix light guide plates, but the devices cannot effectively protect the light guide plates, so that the light guide plates are prone to be damaged during machining, and the cost is wasted; and when the device is used for removing burrs, the outer edges of the light guide plates are generally processed in sequence in a cutting mode, and the outer edges of the light guide plates cannot be synchronously processed, so that the workload is increased, and the working efficiency is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of LED display processing, in particular to a manufacturing process of an LED display backlight source. Background technique [0002] LED display backlight is a light source located behind the LED display. Its luminous effect will directly affect the visual effect of the LED display module. The backlight is mainly composed of a light source, a light guide plate, optical modules, and structural parts; the light guide plate is It is made of optical-grade acrylic sheet or PC sheet. The manufacturing methods mainly include injection molding, photolithography, laser engraving, sandblasting and single-point diamond processing. Injection molding is to fill the molten forming material into the In the closed mold, it is cooled and demoulded, and the light guide plate is initially formed. However, injection molding tends to leave burrs on the outer edge of the light guide plate. Therefore, for the later molding proces...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the production and processing of the light guide plate at present: most of the existing light guide plate manufacturing devices use alloy devices to limit and fix the light guide plate, but this type of device cannot effectively protect the light guide plate, so it is easy to Causes damage to the light guide plate during processing, thereby increasing the scrap rate; and when removing burrs, this type of device generally uses cutting processing to sequentially process the outer edge of the light guide plate, and cutting processing is easy to produce chips, if not removed in time, It will cause scratches on the light guide plate, thereby wasting costs, and the outer edge of the light guide plate cannot be processed synchronously, thereby increasing the workload and affecting work efficiency
