User-defined laser marking method based on handwriting screen

Abstract

The invention discloses a user-defined laser marking method based on a handwriting screen. The method comprises the following steps that a semi-transparent semi-reflecting mirror is adjusted, so thatlasers of a laser device is coaxial with an image of a CCD camera; a galvanometer is corrected, so that the laser marking effect is not distorted; the CCD camera is calibrated, so that an image pixelcoordinate position matches an actual position; user-defined drawing is carried out in a software interface video area by using the handwriting screen; a trajectory of a drawn image is obtained through calculation; the trajectory is converted into marking points, and a marking object is generated by the marking points; and the marking process of the marking object is completed. According to the user-defined laser marking method based on the handwriting screen, the marking object is completely user-defined, the operation is simple, the control is accurate, the speed is high, the method can be applied to various marking scenes, and the marking efficiency and operability are improved.

Description

Technical field [0001] The invention relates to the technical field of laser marking, in particular to a custom laser marking method based on a handwriting screen. Background technique [0002] At present, the application of laser marking technology in domestic and foreign industries is gradually being valued by people. For different industries and needs, various new marking systems are emerging in an endless stream. It is replacing traditional marking methods with its unique advantages, such as stamping, Printing, chemical corrosion, etc., mark Chinese characters, numbers, graphics, etc. on the surface of various mechanical parts, electronic components, integrated circuit modules, instruments, meters, motor nameplates, tools, and even food packaging. The field has been widely used. [0003] However, the marking objects of the marking machines used in industry are relatively fixed. Generally, the marking objects are divided into: points, lines, ellipses, circles, rectangles, text ...
