Description

Technical Field

[0001] This utility model relates to the field of laser marking machine technology, and in particular to a high-speed dual-light source automatic focusing laser engraving machine. Background Technology

[0002] Laser marking machines are characterized by high precision, high speed, minimal pattern deformation, and simple operation. They can engrave on various materials, and the engraving light sources include "blue light," "red light," and "violet light."

[0003] However, existing laser marking machines have the following drawbacks: 1. Because the new shape of the object cannot be determined, most machines on the market are either semi-automatic or manual focusing. 2. Currently, most engraving machines use a single light source, either red or blue light, limiting their application scenarios. Red light is suitable for metal objects, while blue light is suitable for wood, leather, and other everyday items. Summary of the Invention
