What are the characteristics of CCD visual positioning laser marking machine

Laser marking technology is one of the many applications in the laser processing industry. Laser marking is the use of high-energy-density laser to locally irradiate the workpiece, which causes the surface material to evaporate or undergo a chemical reaction of color change, leaving an imprint as a permanent mark. Various characters, symbols, patterns, etc. can be marked. Today's industry is moving towards automation and intelligence. With the continuous improvement of product quality, the production process has become more stringent. The application of machine vision technology in all walks of life is becoming more and more extensive, and the same is true in the laser industry. The application of machine vision technology in the laser industry is also becoming more and more extensive. As a high-tech and high-precision industry, machine vision technology has become more and more widely used in human eyes and brains. At present, science and technology continue to develop at a high speed, and strive to bring forth the new. CCD vision positioning has also appeared in laser marking applications.

The CCD machine vision system consists of a camera, lens, light source, image processing unit (or image capture card), image processing software, communication/output equipment, etc. The CCD visual positioning system mainly uses machines to replace human eyes for measurement and judgment. The use of CCD visual positioning laser marking machine can greatly improve the flexibility and automation of production. On the basis of traditional marking machines, the use of vision system to assist laser marking can make the advantages of laser processing more comprehensive and solve problems. For the accuracy of marking, first polish the product, then make a template for the product and save it. Third, use the high-precision CCD camera to locate the current position of the product, visually locate one or more products collected, calculate the XY coordinates and deflection angle of the workpiece, and transmit the product position information to the marking card and the workpiece through the computer . The location information is transmitted to the marking card through the computer. The scanning galvanometer of the vision laser marking machine can achieve precise marking. The position information of the workpiece is transmitted to the marking card through the computer. The workpiece is within the scanning range of laser marking to achieve precise marking. Marking; the process has strong adaptability and high workpiece positioning accuracy. Laser engraving machine
