Laser marking system

Abstract

The invention discloses a laser marking system. The system comprises infrared scanning equipment, laser equipment, a scanning identification module, an information transmission module, a workpiece marking preparation end and a workpiece marking completion end; the workpiece marking preparation end comprises an image acquisition module, a data acquisition module and a to-be-marked workpiece position identification module, wherein the image acquisition module is used for acquiring the contour and the alignment mark of a to-be-marked workpiece and forming a first image; the data acquisition module is used for acquiring a real-time actual coordinate and a workpiece intrinsic coordinate value; and the to-be-marked workpiece position identification module is used for solving a center coordinateand a rotation angle according to the real-time actual coordinate; the workpiece marking completion end comprises a projection module and a control module, the projection module projects a rotated marking pattern to a real-time projection coordinate, and the control module is used for controlling the laser equipment to carry out laser marking on the to-be-marked workpiece. According to the laser marking system, the marking pattern to be projected is rotated by solving the rotation angle, so that deviation between the position of the marked pattern and the preset position is effectively avoided, and the product yield is improved.

Description

technical field [0001] The invention relates to the technical field of laser marking, in particular to a laser marking system. Background technique [0002] Laser marking technology is one of the largest application fields of laser processing; laser marking is a chemical reaction in which a high-energy-density laser is used to locally irradiate the workpiece to vaporize the surface material or undergo a color change, thereby leaving a permanent mark. A marking method; laser marking can print a variety of text, symbols and images. [0003] In the prior art, when laser marking a workpiece, operators or mechanical transmission equipment are required to send the workpiece to be marked into the processing area, often due to deviations in the placement position, resulting in various characters and symbols printed out And images cannot be located in the ideal position on the workpiece to be marked, making the processed workpiece a defective product.
