Abstract

The invention relates to the field of laser equipment, in particular to laser equipment and a laser scanning galvanometer array calibrating method. The laser scanning galvanometer array calibrating method includes steps of acquiring images corresponding to operations of a laser scanning galvanometer array by a calibrator, processing the images by the calibrator so as to obtain calibration values of various scanning galvanometer; generating actual scanning positions by the scanning galvanometer so as to scan according to the calibration values. By the laser equipment and the laser scanning galvanometer array calibrating method, operation quality in a large operation area is ensured under the condition that manufacturing accuracy requirement of the equipment can be reduced.

Description

technical field [0001] The invention relates to a laser device, in particular to the correction of a laser scanning vibrating mirror array of the laser device. Background technique [0002] Traditional laser equipment, such as laser marking machines, have a fixed scanning range of the galvanometer, which cannot scan and mark large areas. The existing laser equipment that can realize large-area operations is realized by using the arrangement and combination of scanning galvanometers. In order to ensure the quality of work in large-area operation areas, the manufacturing accuracy of this kind of laser equipment is very high. . The reason why high manufacturing precision is required is that once a certain degree of positional deviation occurs between the galvanometers in the scanning galvanometer group due to factors such as machining, the processed products in this case , For example, the marked shape or label will be distorted. For example, when a series of parallel lines a...
