Description

Technical Field

[0001] The utility model relates to the technical field of popular science teaching aids, in particular to a simple laser engraving machine. Background Art

[0002] Laser engraving is an advanced manufacturing technology that uses a high-energy-density laser beam to accurately carve detailed patterns, text or three-dimensional structures on various materials. The working principle of this technology is that the light beam emitted by the laser is focused by the optical system to form a very small and extremely concentrated light spot. This light spot is scanned at high speed, converting energy into heat, and partially melting, evaporating or removing materials (such as metals, plastics, wood, glass, stone, ceramics, etc.), thereby forming the desired morphology. With the development of laser engraving technology, laser engraving technology has also entered campuses. In order to let more students understand laser engraving technology, some simple laser engraving machines will be designed to facilitate display to students for learning.

[0003] At present, the simple laser engraving machine used for teaching usually installs the laser engraving head on a driving structure with multiple degrees of freedom, and then uses the driving structure to control the laser engraving head to translate and engrave. Although this simple laser engraving machine is easy to operate, the translation efficiency of the laser engraving head is low during the translation engraving process on multiple degrees of freedom, thereby reducing the laser engraving efficiency.

[0004] In summary, there is a need for a simple laser engraving machine with efficient engraving. Utility Model Content
