Problems solved by technology

Due to the intermittent movement, the production efficiency is very low
Moreover, due to the existence of errors such as optical devices, optical path structure, mechanical precision, and motion control, this splicing method will produce different degrees of seam problems during the production process, which will affect product quality; also have a greater impact

Embodiment Construction

[0015] With reference to accompanying drawing, the present invention is further elaborated in conjunction with following embodiment:

[0016] Such as figure 1 , 2 As shown, a method for large-scale laser engraving of the present invention comprises the following process steps:

[0017] Set the scanning amplitude and width of the vibrating mirror according to the amplitude of the large-scale picture to be laser engraved;

[0018] Make full use of the high-speed characteristics of the galvanometer scanner, and set the continuous scanning and engraving within the effective working range of the galvanometer from one direction;

[0019] The vibrating mirror moves forward continuously under the control of the platform, thus forming an engraving area covering a whole line, and then scans and engraves the next line until the entire graphic scanning and engraving ends;

[0020] When the galvanometer is scanning the engraved graphics, it has been continuously moving relative to the w...

Abstract

The invention discloses a large-area laser engraving method, which comprises the following steps that the high-speed characteristics of a galvanometer scanner with the adjustable scanning amplitude and width are utilized for carrying out continuous scanning engraving in the effective work range of a galvanometer, the galvanometer does continuous relative movement through being controlled by a platform, so an engraving region covering a whole line is formed, and then, the scanning engraving on a next line is carried out until the whole pattern scanning engraving completion process step. The large-area laser engraving method has the advantages that the continuous scanning engraving method is utilized, errors generated through reasons of light path structure and mechanical precision and moving control can be reduced, and the service life of equipment is prolonged. Splicing marks generated during spaced engraving of large-area patterns in the galvanometer fixed amplitude divided regions can be avoided and reduced, the product quality is improved, and meanwhile, the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of laser engraving, in particular to a process method for continuous laser scanning engraving of medium and large formats. Background technique [0002] At present, the quality and characteristics of products produced by large-format laser engraving have been widely recognized by the market, but the low production efficiency of existing technologies has formed a major obstacle to large-scale promotion and application. On-the-fly marking technology is only aimed at small data volumes, and the continuous operation method of the pipeline cannot eliminate the splicing traces of engraving large-format graphics. Inkjet printing technology scans line by line, but the inkjet head is a fixed array and ejects ink at the same time, that is, the width of a line is fixed. Since the galvanometer can only work in a relatively fixed and small range, the area of ​​the graphics engraved by the laser is limited, and the size ...
