Problems solved by technology

[0002] At present, in order to meet the requirements of automatic data collection and quality traceability for the entire life cycle of rubber parts, it is necessary to print two-dimensional codes on rubber parts. The current method of marking two-dimensional codes has the following disadvantages: After rubber parts are marked by laser, There is basically no color difference between the two-dimensional code and the rubber substrate, which makes it difficult to read the printed two-dimensional code, which brings certain difficulties to the application technology of the two-dimensional code on rubber parts; with general methods, such as inkjet , silk screen printing and other methods are difficult to retain on the rubber substrate; it is impossible to read repeatedly
