Method and equipment for coloring and marking laser

Abstract

The invention discloses method and equipment for coloring and marking laser and relates to the field of laser counterfeiting. The method comprises the following steps of: uniformly spraying imported pigment powder on materials which can be realized by the traditional method or have poor counterfeiting requirement, such as glass, ceramic (enamel), aluminum, alloy, metal with high light intensity and the like; then drying; irradiating the surface of the coating by using gas laser bundle with the infrared light frequency band wavelength being 10.64nm; completely inversing and focusing through a two-dimensional scanning system; marking any text; and flushing after marking to reserve pigment and matrix fusion used by the laser bundle at high temperature, i.e. the text which has high contrast ratio and favorable texture and cannot fade forever. The method cannot be realized by the traditional method.

Description

technical field [0001] The invention relates to a brand-new laser anti-counterfeiting mark and equipment, in particular to a method and equipment for laser coloring and marking anti-counterfeiting. Background technique [0002] At present, with the development of my country's industrial economy and the impact of the financial crisis, the replacement of traditional marking methods and equipment has been accelerated. As a high-tech, laser is a more advanced marking processing method that conforms to market demand and conforms to The brand strategy direction of the enterprise and the concept that innovation is the foundation of the enterprise's survival. [0003] In the brand strategy of an enterprise, the anti-counterfeiting mark is the top priority of the brand strategy. Anti-counterfeiting marks are traditionally pasted, printed, transferred on the surface of the mark, or marked on the packaging of the goods, or marked on the accessories of the goods (such as commodity tags,...

AI Technical Summary

Problems solved by technology

[0004] In the glass industry we are familiar with, anti-counterfeiting is mainly based on printing, and it is easy to fall off after repeated high temperature, humidity, and friction under natural conditions, which cannot achieve the anti-counterfeiting effect of the logo; in the sanitary enamel and ceramic industries, secondary firing is used The anti-counterfeiting method is used to make anti-counterfeiting marks, the yield is not high, and the marks are not easy to control during the firing process, and there are unevenness, deformation, etc.; the anti-counterfeiting of high-gloss metal products is currently mainly based on silk screen printing, which does not meet environmental protection regulations and is easy to produce. Shedding; the aluminum and alloy products industry adopts stamping, silk screen printing, corrosion and other methods, which are prone to deformation, logo falling off, cumbersome procedures, and high additional costs.
