Embodiment Construction

[0017] See figure 1 As shown, this is an embodiment of a beam rotating galvanometer scanning focusing processing system of the present invention, and the material to be processed is a stainless steel sheet with a thickness of 1 mm. 1 is the incident beam expansion collimated beam, the beam diameter is 5 mm, 3 is the inclined flat glass, the thickness is 1 mm, and the inclination angle is 18 degrees, 4 is the collimated output beam, the collimated beam 1 and 4 are parallel, and the distance is 100 microns, and 2 is The beam rotator barrel, 3 is fixed inside 2, and 2 is fixed inside the high-speed hollow motor, which can rotate at high speed, so that the beam 4 actually rotates at high speed around the centerline of the beam 1 as the axis, and the rotation diameter is 200 microns. 9 is the first mirror of the vibrating mirror, which is clamped by the main shaft 10 of the vibrating mirror motor 11, and 4 is reflected by 9 to output a collimated beam 8. When the beam 4 rotates in ...

Abstract

The invention, which belongs to the field of laser processing, relates to a light beam-rotating galvanometer-scanning focused processing system. The system is mainly characterized in that: the system combines the light beam-rotating focused laser processing method and the galvanometer-scanning laser processing method into a novel processing method, which can form a wide cut, and thereby sprue can be conveniently spurted out; if the distribution of laser is Gaussian distribution, then laser processing has the laser processing effect of Gaussian intensity distribution, and has a laser processing effect capable of achieving flat-top laser; nanosecond laser is utilized to achieve the processing effect of ultrashort-pulse width laser, however, by comparison, the processing efficiency is greatly increased; the control is simple and flexible, the speed can be quickly increased and decreased, the size is small, and the cost is low.

Description

[0001] Technical field The present invention belongs to the field of laser processing, especially the fields of laser milling, cutting and drilling. Background technique [0002] Rotating mirror scanning system, its working principle is to expand the laser beam derived from the resonant cavity, reflect it through two stepping motor-driven mirrors installed at 90° in space, and output it after being focused by the F-theta field mirror Acting on the processing object, the rotation of the mirror makes the laser action point on the working plane move on the X and Y axes respectively, and the two mirrors work together to make the laser move in a straight line and various curves on the working plane. [0003] The galvanometer scanning processing technology is the same as that of the rotating mirror scanning system. This typical control system uses a pair of folding mirrors. The difference is that the stepping motor driving the lens is replaced by a servo motor. In this control system...
