example 1

[0018] Step 1: Select the logo of the merchant as a picture file, use laser engraving, and the computer point cloud system to process the logo picture as a point cloud to generate a point cloud file.

[0019] Step 2: Select the transparent material used for product packaging—k9 glass, and clean the glass surface with alcohol.

[0020] Step 3: Import the point cloud generation file to form the point cloud marking data software. By controlling the parameters of the green laser, the repetition frequency is 1500Hz, the laser pulse width is 65μs, the laser power is 532wm, and the focus spot is 30μm. The moving speed of the processing platform is 16000p / s, and the scanning speed of the galvanometer is 3000bit / ms.

[0021] Step 4: Run the scanning control software, import the point cloud file generated in step 1, and put the materials processed in step 2 into the fixed position of the processing platform. Run the internal carving system. When the internal engraving program is over,...

Abstract

Disclosed is an internal laser writing method capable of being used for anti-counterfeiting judgment of commodities packaged by transparent materials. According to the method, a point cloud data file is generated by a selected pattern; the pointed cloud data file is lead in to form point cloud marking data software, the repetition frequency of a laser device is adjusted to range from 1500Hz to 1800Hz, the laser pulse width ranges from 50 micron seconds to 65 micro seconds, the laser power ranges from 532mw to 760mw, the focusing facula is 30 micro meters, the moving speed of a processing platform is 16000p / s, the scanning speed of a galvanometer is 3000bit / ms, and internal laser carving is conducted on the internal surfaces of materials. According to an anti-counterfeiting technology, markings are marked on the inner surfaces of the materials, and consumers can clearly see the anti-counterfeiting marks only after clearly identifying angles and marking patterns. The internal laser writing method effectively avoids the lawless behaviors that lawless persons reproduce adulterated wine after recycling wine bottles to deceive consumers, and is suitable for anti-counterfeiting judgment of commodities packaged by all kinds of transparent materials.

Description

Technical field: [0001] The invention belongs to product anti-counterfeiting technology, in particular to invent a laser internal writing method that can be used for anti-counterfeiting of goods packaged in transparent materials. Background technique: [0002] Due to the rapid development of modern technology, counterfeit and shoddy products are becoming more and more rampant, especially products packaged in transparent materials such as famous wines. At present, famous wine manufacturers still use special bottle caps or labels on wine bottles to prevent counterfeiting. However, criminals recycle used wine bottles, fill them with fake wine, repackage them, make huge profits, and deceive consumers. Therefore, how to effectively prevent counterfeiting is an urgent problem to be solved at present. [0003] Based on the above problems, the present invention proposes a technical method for anti-counterfeiting of commodities packaged in transparent materials. This method uses a ...
