Laser roller film engraving machine

Abstract

The invention relates to the field of roller laser processing system, more particularly to a laser roller film engraving machine. Being a relatively advanced plate making way at present, roller film engraving technology is mainly characterized in processing in that: according to the trace of plate pattern, laser is applied to a protective layer which is pre-coated over the surface of a roller, the part of the surface of the roller, which is exposed due to the falloff of the protective layer, is the plate pattern to be processed, and the roller is then subject to corrosion treatment to finallyform the plate pattern. As a special machine aiming at the above processing way, the laser roller film engraving machine comprises: a graphic and image processing system, a control system, a mechanical system, a laser and an optical system, wherein the optical system comprises an acoustic optic deflector to achieve the light-splitting and time-sharing control for laser, so that the processed plate pattern is more exquisite, and a double-layer optical fiber laser generator is adopted to realize high stability of laser power and excellent quality of light beam.

Description

Technical field [0001] The invention involves the field of rolling laser processing systems, which specially involves a laser roller carving machine. Background technique [0002] In recent years, the roller carving film technology has become a more advanced version of the version. The main processing characteristics are: the use of the laser according to the printing pattern trajectory on the pre -coated protective layer on the surface of the roller.The printing pattern is corroded and cleaned, and the printing pattern is finally formed.However, the current laser carving machines are mostly processed by the laser beam directly on the version of the roller cylindrical surface, and there are no laser carving equipment for the above processing methods. [0003] China Patent CN1299723 has disclosed a system of laser carving rollers, including: carving device of laser rollers, CCD cameras, computer control parts, and circulating water cooling and auxiliary gas devices used for laser....

AI Technical Summary

Problems solved by technology

The device uses multiple laser beams to focus and combine beams, which improves the processing efficiency, but there are still defects: the device uses more than two YAG lasers, but the beam quality of the YAG laser itself is not high, and more than two YAG lasers require two sets of optical paths system, which increases the cost
