Laser processing production process of light guide plate

Abstract

The invention provides a laser processing production process of a light guide plate. The production process comprises the following steps: step 1, providing a laser processing device capable of operating a light guide plate graphic design software and a raw material of the light guide plate; step 2, configuring graphic parameters of the light guide plate according to the distribution of incident light sources and light guide requirements, and forming a light guide plate graph without 'focal point'; step 3, generating processed data files, and transmitting the processed data files to a device controller; step 4, placing the raw material of the light guide plate into the laser processing device; and step 5, starting the laser processing device and carrying out processing. According to the production process of the laser processing light guide plate, the raw material of the light guide plate is processed by the laser processing device which operates the light guide plate graphic design software, one lattice point in the light guide graph generated by the light guide plate graphic design software can be shaped only by emergent light sculpting for one time, the 'focal point' phenomenon can be avoided, and the production efficiency is improved when the quality of the light guide plate is guaranteed.

Description

technical field [0001] The invention relates to the field of light guide plate processing, in particular to a production process for laser processing light guide plates. Background technique [0002] The light guide plate is a high-tech product that transforms the line light source into a surface light source. Its principle is to use the optical grade acrylic plate to absorb the light from the LED lamp to stay on the surface of the acrylic plate. When the light hits each When the light guide point is used, the reflected light will diffuse to all angles, and then destroy the reflection condition and be emitted from the front of the light guide plate. Through various light guide points of various densities and sizes, the light guide plate can be made to emit light evenly. At present, the methods of processing light guide mainly include silk screen printing, injection molding, etching, engraving and so on. No matter which method is used, it is first necessary to design the pat...

It is difficult to process this kind of dot map with the existing laser engraving machine. Either convert the dot map into a bitmap or vector filling map, use the ring LED light bar 100 to set on the outside of the circle, and then use the progressive scanning method for engraving. , so that a qualified light guide plate can be processed, but the efficiency is extremely low

like figure 2 As shown, either the method of cutting the circular dotted line diagram is used for processing, which can ensure the fast processing, but there will be a "key" 300 phenomenon at the intersection of the cutting line (circle) at the head and tail, resulting in a decrease in the quality of the light guide plate
