Laser marking method, laser marking device and computer readable storage medium

Abstract

The invention discloses a laser marking method. The laser marking method comprises the following steps of obtaining repeated marking times and a target pattern, and copying the target pattern according to the repeated marking times to obtain the target pattern corresponding to each marking; generating an initial position of each marking according to the target pattern, so that the initial positions of marking are different each time; and sequentially controlling a laser marking device to mark according to the initial position and the corresponding target pattern until marking times reach the repeated marking times. The invention further discloses the laser marking device and a computer readable storage medium. The initial positions of marking are generated on the repeated marking pattern,so that the initial positions of marking are different each time; and marking is started according to the initial position of marking, so that the problem that dents are more obvious during a repeatedmarking process is solved, and the laser marking effect is improved.

Description

technical field [0001] The present invention relates to the technical field of laser marking, in particular to a laser marking method, device and computer-readable storage medium. Background technique [0002] When marking a workpiece with a laser, some marks have certain requirements for the marking depth, so it is usually necessary to mark the same figure at the same position multiple times, which is shown as copying and pasting the same figure multiple times in the control interface. To achieve multiple markings. [0003] However, multiple graphics after copying and pasting are overlapped together. Due to the high energy of the first pulse light during marking, the marking strokes are heavy, and dents are produced on the workpiece. When marking, because the starting position of multiple markings is the same, the dent will be more obvious, resulting in poor laser marking effect. [0004] The above content is only used to assist in understanding the technical solution of ...
