Laser marking system, closed pattern filling algorithm thereof, and storage medium

Abstract

The invention discloses a closed pattern filling algorithm via laser marking. A coordinate system is established according to a target closed pattern, and at least one target filling area is determined; the target filling area is segmented into scan lines, and the coordinate of an intersection point between each scan line and the outer contour of the target closed pattern in the target filling area is obtained; the coordinates of the intersection points are recorded; a corresponding array is generated according the recorded coordinates; and according to the coordinates of the intersection points in the array and a marking scanning manner of a laser head, a laser marking path in the target filling area is calculated directly. It is not required to obtain the outer contour of the closed pattern or the calculate the scanning path by obtaining contour points along the circumferential direction of the outer contour, so that the computational complexity is low, and the computing speed is high. The invention also provides a laser marking system and a computer readable storage medium.

Description

technical field [0001] The invention relates to the technical field of laser processing, in particular to a laser marking system, a laser marking filling algorithm for a closed figure, and a computer-readable storage medium. Background technique [0002] With the development of laser technology, laser marking machine or laser engraving machine, as a kind of laser processing technology, is becoming more and more prominent in today's industrial field. Because the laser has good directionality, high brightness, good monochromaticity, and high energy density, it is widely used in material processing, marking text, marks, graphics, etc. on the surface of products or workpieces to make Out of commodity logo or handicrafts, etc. [0003] Laser processing equipment such as laser engraving and laser marking has two modes of movement: hooking and cleaning. The outline is a contour movement for generating curves or polygonal tracks; cleaning is a horizontal (or other angle) scanning m...

AI Technical Summary

Problems solved by technology

However, this algorithm usually requires linear interpolation calculation, which has the disadvantages of large amount of calculation and slow calculation speed, and the speed of generating mark content fill lines in this way cannot meet the high-speed requirements, and the calculation of intersection points is very time-consuming, and the fill lines are not accurate. Easy to be right on the scan path
