Problems solved by technology

This structure can generally only be used to process workpieces with a small format, and because it needs to drive a heavy worktable, its positioning speed and dynamic response are poor
Therefore, the current three-dimensional laser engraving machine cannot realize multiple positioning engraving for long workpieces beyond the stroke range of the machine tool, and cannot meet the requirements of engraving high-quality and large-scale workpieces.
At the same time, the existing three-dimensional laser engraving machine can only realize three-axis linkage of X-axis, Y-axis and Z-axis. The whole machine does not have functions such as rotation and expansion, which makes the movement of the machine inflexible and inconvenient to cut workpieces, resulting in low work efficiency. Engraving quality cannot be guaranteed

Description

technical field [0001] The invention belongs to the technical field of laser engraving, and in particular relates to a three-dimensional laser engraving machine. Background technique [0002] Laser engraving technology belongs to a relatively common laser processing technology. Laser engraving processing mainly uses the vaporization effect, photochemical effect and flame erosion effect of laser on the workpiece to achieve the processing effect. Laser engraving has the characteristics of non-contact, low noise, high speed, etc. It is very suitable for engraving and processing of non-metallic materials such as acrylic, rubber, wood, etc., and has been widely used in industries such as advertising, clothing, printing, and handicrafts. [0003] Most of the traditional three-dimensional laser engraving machines adopt a mobile table and fixed beam gantry structure. Generally, this structure can only be used to process workpieces with a small format, and because it needs to drive ...
