Preparation method and device for anti-counterfeiting mark

Abstract

The invention relates to the anti-counterfeiting technology, in particular to a preparation method and implementation device for an anti-counterfeiting mark. The method comprises the following steps that S10, an anti-counterfeiting material is provided, and UV glue is provided; S20, even mixing is carried out; S30, micro-spraying is carried out; S40, light curing is carried out; and S50, checking is carried out. Light curing is ultraviolet light curing, and the step of light curing comprises the substep of precuring and the substep of fast curing. According to checking, online digital recognition is adopted, and defective products are removed from a production line. The anti-counterfeiting material comprises flaky amorphous silicon modules, and the amorphous silicon modules are provided with hollowed areas. The anti-counterfeiting material further comprises metal modules, and the metal modules are inset in the hollowed areas. The device comprises a conveying device, an alignment device, a position adjustment device, two glue storage devices, a micro-spraying device, a light curing device and a checking device. The preparation method and implementation device for the anti-counterfeiting mark adapt to high-speed automatic production, are made of multiple materials, and have the stereoscopic impression, and imitation is hard.

Description

technical field [0001] The invention relates to anti-counterfeiting technology, in particular to a method for preparing an anti-counterfeiting mark and a device for implementing the method. Background technique [0002] In the anti-counterfeiting technology of the prior art, watermarks, colored fibers, fluorescent ink printing, shapes and random distribution of micro-dots or tiny marks are mostly used as anti-counterfeiting means. [0003] As disclosed in Chinese patent document CN101673341A, a micro-dot anti-counterfeiting method comprises the following steps: (1) providing a micro-dot; (2) providing a kind of glue, and mixing the micro-dot into the glue; Dot glue mixed with micro-dots on the carrier; (4) solidify the glue; (5) take pictures of the glue drops to form the original comparison picture; (6) save the original comparison pictures into the background database; Compare the picture; (8) read the original comparison picture of the background database, compare it wit...

Problems solved by technology

[0005] However, the anti-counterfeiting technology disclosed in the above-mentioned patent documents still has deficiencies in practice. The former sets glue droplets on the carrier by dispensing, and the amount of glue is large, and the amount of micro-dots is correspondingly large, and the cost is relatively high. On the one hand, the glue drop has a strong sense of convexity and concave, and is easy to wear; the latter is not suitable for high-speed automatic production operations. Micro-dot anti-counterfeiting is only an early anti-counterfeiting method, and the anti-counterfeiting information is single, which is in urgent need of improvement.

The above existing technologies can solve most of the anti-counterfeiting needs. However, the anti-counterfeiting materials composed of a single material are easy to be imitated, and the uniform gray tone has no sense of hierarchy and three-dimensionality, which still cannot meet the high-end needs. Therefore, it is necessary to continuously innovate and improve
