Problems solved by technology
[0003] The traditional coding control of the laser anti-counterfeiting coder is realized by setting the time interval, that is, the anti-counterfeiting code is coded every once in a while. This control method can control the anti-counterfeiting coder. Automatic control, but it is prone to mistakes, misses, etc., which not only causes power loss, but also easily leads to an increase in the defective rate of finished products and increases production costs.

Description
technical field [0001] The invention relates to the technical field of anti-counterfeiting code engraving, in particular to a laser anti-counterfeiting code engraving method and an automatic engraving device. Background technique [0002] Laser coding refers to the use of a high-energy laser beam to irradiate the surface of the workpiece, and the light energy instantly becomes thermal energy, which makes the surface of the workpiece evaporate rapidly, thereby engraving any desired text and graphics on the surface of the workpiece. Compared with ink jet coding technology, laser coding technology is a more advanced technology. It realizes the marking of any special-shaped surface by non-contact method, the workpiece will not be deformed, and will not generate internal stress; secondly, it has clear, permanent, beautiful marking, fast coding speed, low operating cost, no pollution, and can significantly improve The grade of the coded product. Based on the above advantages, it...
