Technical Field

[0001] This utility model relates to the field of laser cutting device technology, specifically to a novel collimation module assembly. Background Technology

[0002] With the development of science and technology, my country's manufacturing industry is facing a transformation towards high-end and intelligent manufacturing. As a basic processing technology, laser technology is increasingly penetrating all aspects of industrial production. Laser cutting is a technology that uses a high-power-density fiber laser beam to irradiate the material being cut, causing the irradiated part of the material to vaporize and form tiny holes. As the fiber laser beam moves, the holes are continuously formed to complete the cutting process.

[0003] In actual production and processing, zoom lenses are usually used to meet the requirements of laser cutting heads to flexibly adapt to different types of workpieces. Although existing zoom lenses can flexibly adjust the focal length of the laser cutting head, the overall structure is complex and increases the weight of the laser head to a certain extent. This makes it necessary to purchase a larger load-bearing robotic arm, which increases production costs and is not conducive to improving the competitiveness of enterprises. Utility Model Content
