Abstract

The invention discloses an automatic correction method and system for laser equipment galvanometer marking, which belongs to the field of laser equipment correction, and is used for automatic correction of marking graphics, solving the problem of subjective judgment errors caused by manual measurement of marking correction in the prior art Large, and it will take a lot of time and labor costs, including: correcting the two-dimensional motion platform of the laser marking machine; engraving marking graphics on the corrected two-dimensional control platform, and calculating the distortion data of the marking graphics; According to the standard size data of the distortion data and the standard mark figure, the mark figure is corrected; thereby the link of manually measuring the mark is eliminated, which not only avoids the occurrence of large subjective judgment errors caused by manual measurement, but also reduces the The time cost and labor cost of manually measuring the mark.

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 direction of the X-axis or Y-axis, 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 o...
