Abstract: In the field of vehicle manufacturing, it is common to use laser marking during the assembly and welding process of passenger cars. However, in the manufacturing process of commercial vehicles, especially in the heavy truck industry, the common marking equipment for vehicle identification number (VIN) engraving process still uses needle engraving machines. This article introduces the basic requirements for commercial vehicle VIN engraving, compares the characteristics of needle engraving and laser engraving, and solves the problem of interference in robot laser engraving. To achieve fully automated production of commercial vehicle VIN engraving, we hope to provide a hybrid production VIN laser engraving process idea.

Key words: vehicle identification number engraving; robot engraving; laser engraving; laser marking
