As we all know, laser marking technology is one of the larger application areas in the laser processing industry. Laser marking is a marking method that uses high-energy-density lasers to locally irradiate the workpiece to vaporize or change the color of the surface material, thereby leaving a permanent mark. Laser marking can produce various words, symbols and patterns. As modern industry is developing towards a high degree of 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. It can also be seen in fully automatic equipment. In some high-tech and high-precision industries, pure mechanical positioning accuracy can no longer meet customer requirements. Machine vision uses machines to replace human eyes and brains for positioning and judgment. , Measurement and identification. In the current high-speed development of technology, CCD vision positioning has emerged in the application of laser marking.

The CCD machine vision system is composed of a camera, lens, light source, image processing unit (or image capture card), image processing software, communication/input output unit, etc. The CCD vision positioning system uses a machine to replace the human eye for measurement and judgment. The CCD visual positioning laser marking machine can greatly increase the flexibility and automation of production. Based on the traditional marking machine, the visual system can assist the laser marking, which can make the advantages of laser processing more comprehensive and solve the problem. For the accuracy of the target, first polish the product to ensure that the product has a clear shape, and then make a template for the product and save it. Then use a high-precision CCD camera to locate the current position of the product, and visually locate one or more products collected in real time, calculate the XY coordinates and deflection angle of the workpiece, and transmit the product position information to the marking card through the computer in turn , As long as the workpiece is within the processing range of the laser marking scanning galvanometer, accurate marking can be achieved. The workpiece can be loaded at will, that is, even if the position is different each time, the processing position is accurately identified, precise positioning, and precise marking. The shape of the processed product can be recognized as round, square, and irregular shapes; this process has high adaptability, and is especially suitable for small products in various industries, heavy workload, difficult positioning of materials, time-consuming loading and unloading, or in some cases. It is suitable for the dangerous working environment of manual operation or occasions where manual vision is difficult to meet the requirements. It can eliminate the processing of positioning trays and fixed fixtures, which greatly saves and reduces costs, reduces manual participation and laser marking processing cycles, and greatly improves Improve production efficiency and automation, and improve product quality.
