Problems solved by technology

At present, a laser needs to be equipped with a set of beam shaping and focusing system, a galvanometer, and a processing platform. In order to perform multiple processing operations at the same time, a corresponding number of laser processing equipment must be purchased, so the cost of equipment configuration is relatively high.

Abstract

The distributed laser processing system includes a laser; a beam splitter in the output of the laser; the first branch comprising a light shutter, a frequency modulator, a rotating half-wave plate, a polaroid, a laser beam shaping and focusing system and a vibrating mirror and connected to the output of the beam splitter; the second beam splitter or a total reflector; the second similar branch; and a computer connected to all the vibrating mirrors. The laser beam from the laser is treated through beam splitting, power regulation and shaping for several laser processing jobs, such as welding, cutting, engraving, etc in obviously lowered production cost.

Description

technical field [0001] The invention relates to a laser processing system, in particular to a distributed laser processing system capable of performing multiple laser processing operations simultaneously, and belongs to the technical field of laser precision processing and manufacturing. Background technique [0002] Laser processing is an energy beam processing method, which has the characteristics of high brightness, good directionality and good monochromaticity. In theory, it can be focused on a small spot with a size similar to the wavelength of light, and the power density at the focus can reach 10 7 ~10 11 W / cm 2 , the temperature is as high as 10,000 degrees. Laser processing makes the material melt and vaporize instantaneously and rapidly under the focused laser irradiation, and generates a strong shock wave, which makes the molten material splash explosively and realize the removal of the material. Combined with computer numerical control technology, laser proce...
