Abstract

The invention discloses an automatic correction method and system for a galvanometer mark of a laser device, which belong to the field of laser device correction. The method and system are used for automatically correcting a mark pattern. The problems that manual measurement used by mark correction in the prior art leads to large subjective judgment error and costs a lot of time and labor costs inthe prior art are solved. The method comprises the steps that a two-dimensional motion control platform of a laser marking machine is corrected; the mark pattern is laser-carved on the corrected two-dimensional control platform, and the distortion data of the mark pattern are calculated; and according to the distortion data and the standard size data of a standard mark pattern, the mark pattern is corrected. Manual measuring of the mark is eliminated. Large subjective judgment error caused by manual measurement is avoided, and time and labor costs of manual mark measurement are reduced.

Description

technical field [0001] The invention relates to the field of laser equipment calibration, in particular to an automatic calibration method and system for laser equipment vibrating mirror marks. Background technique [0002] Laser marking machine is to use laser beam to make permanent marks on the surface of various materials, so as to carve exquisite patterns, trademarks or characters. [0003] During the use of the laser marking machine, the scanning lens will be concave or convex in the X-axis or Y-axis direction, or the mark will be trapezoidal or parallelogram due to the deviation of the installation position of the scanning galvanometer (standard The mark is a square), or due to the unevenness of the scanning lens and the nonlinearity of the scanning galvanometer, the size of the entire marking range is not uniform, which reduces the accuracy of the laser marking machine. [0004] The existing method of correcting marks is to import a square figure with a size of 100mm...
