Embodiment Construction

[0026] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.

[0027] Referring to Fig. 1, the present invention includes an optical system A and an acquisition control processing device B. Optical system A is equipped with He-Ne laser 1, plane mirror 2 with both transmission and reflection functions, CO 2 Laser 3 , beam expander collimator 4 , positive rotation prism and negative rotation prism 5 and focusing lens 6 . The laser beam emitted by the He-Ne laser 1 is coupled to the beam expander collimator 4 through the plane mirror 2 which has both transmission and reflection functions, and is used as an illumination and imaging light source for the pointing system and the information collection processor 8 . CO 2 After the laser beam emitted by the laser 3 passes through the beam expander and collimator 4, the divergence angle of the beam is reduced, and a laser beam meeting a suitable aperture size is obtained...

The optical system includes an He-Ne laser, a CO2 laser, a plane mirror, a beam expanding collimator, a positive rotating prism, a negative rotating prism and a focusing lens; and the signal acquiring, signal processing and controlling device includes a signal acquiring and processing unit, a controller and a feedback circuit.

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 ...
