Abstract

The present application relates to a laser marking control method, device, computer equipment and storage medium, wherein the method includes: computer editing the galvanometer motion track and marking data package; parsing the marking data package to obtain the marking data The marking instruction in the package and the corresponding control parameters of the marking instruction; the Q drive is pre-coded according to the corresponding control parameters of the marking instruction to obtain the corresponding pulse signal; when the computer sends the starting marking instruction, the marking The standard card controls the vibrating mirror to move at a constant speed according to the preset trajectory, and the Q drive emits laser pulses according to the corresponding pulse signal. The invention controls the movement of the galvanometer for scanning and the Q drive for precoding in advance. Through the matching of the two, when the galvanometer moves to the point that needs to be marked, it sends a preset pulse, which realizes the cancellation of the galvanometer. In addition, it also cancels the communication delay between the marking card and the laser, shortens the time-consuming of laser marking, and improves the efficiency of laser marking.

Description

technical field

[0001] The invention relates to the technical field of laser processing, in particular to a laser marking control method, device, computer equipment and storage medium. Background technique

[0002] At present, with the development of laser processing technology, the application fields of laser processing technology are becoming more and more extensive. Among them, laser marking technology is one of the largest application fields of laser processing. Laser marking is a marking method that uses a high-energy-density laser to locally irradiate the workpiece to vaporize the surface material or undergo a chemical reaction of color change, thereby leaving a permanent mark. Laser marking can print various characters, symbols and patterns, etc., and the character size can range from millimeters to microns, which has special significance for product anti-counterfeiting.

[0003] At present, laser marking has experienced the development of mask marking, array markin...
