Description

Technical Field

[0001] This utility model belongs to the field of laser processing equipment technology, specifically relating to a laser galvanometer that facilitates splicing printing. Background Technology

[0002] With the development of industrial manufacturing, the demand for large-format, high-precision laser processing is increasing across various industries. For example, the aerospace industry requires the manufacture of large-sized metal components, while automobile manufacturing requires marking and fine engraving on large metal sheets. Traditional single laser galvanometers have limited scanning ranges, typically constrained by lens size and focal length, making them unable to meet these large-scale, high-precision processing needs. For slightly larger workpieces, multiple positioning operations are required, which is not only cumbersome but also introduces accuracy errors, affecting the overall printing quality. The small printing area per cycle and the need for multiple scans to complete the same large workpiece directly increase processing time. Traditional laser galvanometers are sparsely arranged in the same space, resulting in wasted space and a limited arrangement that cannot flexibly configure the number and arrangement of galvanometers according to the shape and size of the workpiece.
