Laser marking is a marking method that uses a high energy density laser to locally irradiate the workpiece, causing the surface material to vaporise or undergo a chemical reaction of colour change, thus leaving a permanent mark. Laser marking can hit a variety of text, symbols and patterns. In modern industrial production, as product quality continues to provide improvement, the production process is also more stringent.
The vision system of the vision laser marking machine is composed of camera, lens, light source, image processing unit (or image capture card), image processing software, communication/input/output unit, etc., similar to human eyes and brain.


The advantages of the integrated system of vision laser marking are as follows:
1、Precisely guide the laser marking position. In the field of view of the machine vision, to provide all-round (product disorderly placement, angle arbitrary placement), high-precision visual positioning.
2、Can choose static or flight guidance laser marking to meet the different needs of customers.
3、Able to automatically calibrate the laser lens through the vision system, thus eliminating the tedious process of manually calibrating the lens.
4, can be marked out for the character recognition (OCR) and barcode, two-dimensional code recognition and identification of comparison, through the network port or serial communication to dock the MES system.
5、Software independent research and development, support for non-standard customisation.
With supporting visual positioning system of the laser marking machine compared to the main advantages of traditional laser marking machine, the product as long as the laser marking scanning galvanometer within the processing range, you can achieve accurate marking, that is, the product position, angle and other information feedback to the laser head, so as to achieve the automatic positioning marking system, that is, each time the position of the processing position even if it is not the same position, the position of the processing of the accurate identification. The shape of the processed product can be round, square, non-regular shapes can be identified; this process is particularly suitable for small products, can be exempted from the positioning of the material tray, fixed fixture processing, greatly saving the laser marking processing cycle.
