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.

Embodiment Construction

[0027] The technical features in the technical solutions provided by the present invention will be further clearly and completely described below in conjunction with specific embodiments.

[0028] The first aspect of the present invention provides a laser anti-counterfeiting code engraving method, the steps include: providing a material containing a coded pattern of recorded information; using mechanical external force to rotate the material, and identifying the coded pattern on the material through an online code reading program. The recognition results screen out normal products and abnormal products; detect the position of the mold opening dividing line of normal products, and obtain the laser marking position based on the position of the mold opening dividing line for laser marking.

[0029] Materials containing coded graphics that record information are the prerequisites for screening normal and abnormal products. The recorded information includes the date of manufacture,...

Abstract

The invention relates to the technical field of anti-counterfeiting code engraving, and specifically further relates to a laser anti-counterfeiting code engraving method and an automatic engraving device thereof. The laser anti-counterfeiting code engraving method comprises the following steps: providing a material containing a coded graph for recording information; rotating the material by usinga mechanical external force, identifying the coded graph on the material through an online code reading program, and screening out a normal product and an abnormal product through an identification result; and detecting the mold opening parting line position of the normal product, and obtaining a laser marking position based on the mold opening parting line position to carry out laser engraving.

Description

technical field [0001] The invention relates to the technical field of anti-counterfeiting code marking, and more specifically relates to a laser marking method for anti-counterfeiting codes and an automatic marking device thereof. Background technique [0002] Laser coding refers to the use of high-energy laser beams to irradiate the surface of the workpiece, and the light energy is instantly converted into heat energy, which causes the surface of the workpiece to evaporate rapidly, thereby engraving any required text and graphics on the surface of the workpiece. Laser coding technology is a more advanced technology than inkjet coding technology. It realizes the marking of any special-shaped surface through a non-contact method, and 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, and no pollution, which can significantly improve The grade of the coded prod...
