Random colorful three-dimensional entity false proof mark and manufacturing device and method

Abstract

The invention discloses a random colorful three-dimensional entity false proof mark and a manufacturing device and method. The pattern of marker particles and a laser moving trajectory are designed through a computer, a sheet is placed on a machining shaft table, focused high-energy pulse spots irradiate the sheet, the marker particles with three-dimensional hollowed-out markers are generated, the marker particles are scattered on transparent colloid or the surface of a marked object randomly, and the random colorful three-dimensional entity false proof mark is formed. By means of the random colorful three-dimensional entity false proof mark and the manufacturing device and method, the cost of raw materials is lowered, the production processes are reduced, production efficiency is improved, emission of waste water, waste materials and waste liquid is reduced, and environmental friendliness is further achieved.

Description

technical field [0001] The invention relates to the field of identification and anti-counterfeiting, in particular to a random colorful three-dimensional solid anti-counterfeiting mark, a manufacturing device and a manufacturing method. Background technique [0002] In the prior art, silicon is generally used as a raw material for etching micro-engraved markers. Although its chemical properties are stable, its cost is too high, which is not conducive to large-scale production. On the other hand, the etching steps are cumbersome, and some of the processes still require manual operations, resulting in a long construction period. Furthermore, the etching process needs to use a large amount of chemical reagents, and there are many waste water, waste liquid, and waste materials, which is not conducive to the requirements of environmental protection production. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior ar...
