Description

Technical Field

[0001] The utility model specifically relates to the field of laser processing, in particular to a spherical workpiece laser micro-hole processing device. Background Art

[0002] Laser engraving is the most commonly used application of laser systems. According to the mechanism of interaction between laser beam and material, laser processing can be roughly divided into two categories: laser thermal processing and photochemical reaction processing. Laser thermal processing refers to the use of the thermal effect generated by projecting the laser beam onto the surface of the material to complete the processing process, including laser welding, laser engraving and cutting, surface modification, laser laser marking, laser drilling and micromachining; photochemical reaction processing refers to the process of irradiating the laser beam to the object and initiating or controlling the photochemical reaction with the help of high-density laser high-energy photons.

[0003] When existing laser processing devices perform drilling processing on different spherical workpieces, different equipment needs to be used for processing due to the different sizes of different workpieces. The application range of the processing is small. Moreover, during processing, since the workpiece is spherical, it is inconvenient to fix it, and the processing is prone to sliding, resulting in poor drilling effect.

[0004] To this end, we proposed a spherical workpiece laser micro-hole processing device to solve the above problems. Utility Model Content
