Laser marking and coding method

Abstract

The invention relates to a laser code assignment method, which is characterized in that the size of a two-dimensional code dot formed by the focus of the laser is reasonably matched with the two-dimensional code dot matrix formed by the uniform size dot matrix, so that the two-dimensional code The coding characteristics of the code laser are adapted to the form and structure of the dot matrix of the code. The method of coding the bottom of the bottle cap realizes high-speed laser coding.

Description

【Technical field】 [0001] The invention belongs to a laser marking and coding method in the field of image processing. 【Background technique】 [0002] With the application of the concept of the Internet of Things, people finally see the practicality of de-conceptualization with less investment and quicker results between the public mobile phone reading and the networking of commodities to realize commodity promotion, commodity anti-counterfeiting identification and commodity big data analysis. technology. [0003] Therefore, regardless of the product, it has become a trend to realize mass mobile phone identification through variable information coding. However, how to carry out commodity coding efficiently and at low cost has become a topic of attention. [0004] For this reason, in the past year or so, there have been many publications of patents in this area. In China, the German coding professional Domiro Company published a paper entitled "A bottle cap, the top or measur...

Problems solved by technology

[0018] The second purpose of the present invention is to solve the problems of low coding efficiency of lasers, large restrictions on coding materials, low coding quality and difficult identification. A product that cannot be changed, and proposes a labeling process that solves all the problems caused by the current laser coding without changing the existing bottle cap material and structure
