Preparation method and device for anti-counterfeiting label

Abstract

The invention relates to an anti-counterfeiting technology, in particular to a preparation method for an anti-counterfeiting label and an implementation device of the method. The method comprises the following steps of 10, providing an anti-counterfeiting material, and providing UV (Ultraviolet) glue; 20, performing uniform mixing; 30, performing micro-sprinkling; 40, performing light curing; 50, performing inspection, wherein light curing refers to UV light curing, and the light curing step is divided into two sub-steps of pre-curing and fast curing; inspection is to reject an unqualified product from a production line by online digital identification; the anti-counterfeiting material is of a flaky structure which is formed by connecting more than two rare earth oxide modules. The implementation device of the device comprises a conveying device, an alignment device, a positioning device, two glue storage devices, a micro-sprinkling device, a light curing device and an inspection device. The preparation method and the implementation device of the method are adapted to the anti-counterfeiting label which is rapidly and automatically produced from multiple materials, has double anti-counterfeiting information and is unlikely to be counterfeited.

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 single anti-counterfeiting information cannot meet the high-end needs. Therefore, it is necessary to continuously innovate and improve
