Title: ANTI-COUNTERFEIT GRAIN CRYSTAL, AND METHOD AND DEVICE FOR MANUFACTURING ANTI-COUNTERFEIT GRAIN CRYSTAL
Abstract:
An anti-counterfeit grain crystal, and method and device for manufacturing an anti-counterfeit grain crystal. The method comprises the following steps: (1) manufacture product fingerprint members, wherein the product fingerprint members are sheet-like grains or asymmetrical three-dimensional grains having a size of 2-100 micrometers; (2) disperse the product fingerprint members in an adhesive; (3) continuously spray, by a lateral dual-charging barrel adhesive supply system, fully transparent droplets of the adhesive on an object to be marked; (4) perform defective product detection, reject a defective product if a defective product is detected, and extract an acceptable product image feature value if an acceptable product is detected, and perform UV curing thereon. The method has a wide range of application, produces a marked product highly integrated with the dispensed adhesive, and provides higher dispersibility, thus facilitating identification.
