Description

technical field

[0001] The invention relates to a laser processing tool, in particular to a laser processing tool with the functions of perforating, cutting, welding and measuring, which integrates light, machine and electricity, and processes related information such as image processing. Background technique

[0002] Laser processing is the main field of laser technology application today, especially in semiconductor and microelectronics industry, automobile industry and shipbuilding industry. In recent years, the demand for laser processing equipment has increased dramatically, but most laser processing equipment can only achieve a single processing requirement. Due to the limitation of the aperture of the laser beam itself, the existing laser drilling devices mostly adopt the scanning cutting processing method to realize the processing of larger apertures. This scanning processing method has disadvantages such as time-consuming and rough processing surface. In order to ...
