Abstract

The invention discloses a method for carrying out laser-micro-engraving marking anti-counterfeiting identification code on the inner surface of a transparent or translucent container. In the method, laser-micro-engraving and a computer point cloud software system are utilized to carry out point cloud process on an anti-counterfeiting identification code; a computer marking software system controls a vibrating mirror and the10ns grade laser beam of a 532nm green laser to act on the surface of a transparent or translucent container according to a point cloud file so that the anti-counterfeiting identification code is marked on the inner surface of the transparent or translucent container, wherein the laser beam of the 532nm green laser has high pulse peak value power and high frequency of pulse laser beam. An anti-counterfeiting identification code is internally engraved on the surface of a glass winebottle, so the laser-micro-engraving marking anti-counterfeiting identification code is never worn. The invention has simple and compact structure, high laser-micro-engraving speed, is suitable for various transparent and colorful glass winebottles, and can be widely applied to laser-micro-engraving marking of winebottles in production lines of distilled spirit, red wine or beer industries.

Description

Technical field [0001] The invention belongs to the technology of product anti-counterfeiting, and specifically designs a method for laser internal engraving and marking of anti-counterfeiting identification codes on the inner surface of a transparent or translucent container. Background technique [0002] Both the laser internal engraving machine and the laser marking machine are laser processing equipment that integrates light, machine and electricity, and are high-tech products that combine laser technology and use it reasonably. The laser internal engraving machine can engrave three-dimensional graphics, images and text in crystal and glass; the laser marking machine can engrave various specific codes and graphics on metal and non-metal surfaces, which are widely used in people's daily life and industrial fields. . [0003] At present, the anti-counterfeiting of wine bottles in the wine industry basically adopts laser coding on the outer surface of the wine bottle box and CO2 ...
