Abstract

The invention provides a blue-violet laser carving system and an engraving method thereof. The blue-violet laser carving system comprises a main driving mechanism, a transverse movement mechanism, a photoelectric encoder, a computer with a control procedure and a controller, wherein the main driving mechanism comprises a main motor, a speed reducer and a main shaft, wherein the main shaft is connected with the speed reducer, the speed reducer is connected with the main motor, and a roller cylinder is connected with the main shaft; the transverse movement mechanism comprises a transverse movement motor, a lead screw and a guide rail, wherein an optical engine is connected with the lead screw, the lead screw is connected with the transverse movement motor, and the optical engine is arranged on the guide rail and can move; the controller is respectively connected with the optical engine, the transverse movement motor, the main motor, the photoelectric encoder and the computer; and a photosensitive material is sprayed on the roller cylinder. The engraving method comprises the following steps of: coating the photosensitive material on the roller cylinder; converting original image data into bitmap data; converting the bitmap data into a control signal of a reflecting type grating light valve and loading the control signal on the optical engine; carrying out laser scanning; and developing and corroding. The system and the method disclosed by the invention have the characteristics that performance is stable, engraving quality is high and the like, and are efficient and convenient.

Description

technical field [0001] The invention relates to a blue-violet laser engraving system and an engraving method thereof, in particular to a blue-violet laser engraving system and an engraving method based on a reflective grating light valve, and is mainly suitable for high-quality printing and anti-counterfeit packaging plate making. Background technique [0002] Laser engraving systems have been widely used in printing and embossing, and high-quality printing and anti-counterfeiting packaging require laser engraving systems with high resolution and fast scanning speed. There are three types of laser engraving systems in the prior art: high-power ablation type, infrared laser type and blue-violet laser type. [0003] High-power ablative laser engraving system adopts CO 2 Lasers, YAG lasers or fiber lasers directly ablate photosensitive materials, and the engraving edges are relatively rough, so they are not suitable for high-quality printing and anti-counterfeiting packaging t...
