The CCD visual positioning laser marking machine technology uses the principle of visual positioning. First, the product is formulated and saved as a standard template. The product is photographed during processing, and the product is compared and positioned by the computer. After adjustment, the product can be accurately processed . The shape of the processed product can be recognized as round, square, and irregular shapes; this process is particularly suitable for small products, which can eliminate the processing of positioning trays and fixed fixtures, which greatly saves the laser marking processing cycle.
