[0002] In the current industrial automation and information-based production process, inkjet marking of products is an important step. Inkjet marking technology can not only provide basic product information, such as product type, batch and production time, but also serve as an important means of product traceability, anti-counterfeiting and quality control. However, traditional inkjet marking technology mostly relies on manual operation or simple automated equipment, which has problems such as low inkjet marking efficiency, high error rate and difficulty in effectively integrating with information systems. With the rapid development of industrial internet technology, the application of the identification resolution system in the manufacturing industry is becoming increasingly widespread. The industrial internet identification resolution system can assign a unique identification code to each product and realize the sharing and traceability of product information through the resolution server. The introduction of this technology has provided new development opportunities for automatic inkjet printing technology. However, there is currently a lack of automatic inkjet printing technology on the market that can fully utilize the Industrial Internet Identifier Resolution System. Most existing inkjet printing systems can only perform simple inkjet printing functions and cannot effectively connect with the Industrial Internet Identifier Resolution System, thus limiting the application of inkjet printing technology in product traceability, quality control, and other fields.
