Optical path design control system and control method of laser etching machine

Abstract

The invention relates to an optical path design control system and a control method of a laser etching machine. The optical path design control system comprises a laser device, a beam expander, a uniform light system, a dynamic focusing system, an objective lens, a galvanometer scanning system, an industrial personal computer and a laser control D/A output card, wherein a laser beam output from the laser device is expanded by the beam expander and then transformed by the uniform optical system, so that the laser beam is distributed more uniformly, and the uniform light system is behind the beam expander in the optical path; the dynamic focusing system is behind the uniform light system in the optical path; the objective lens is behind the dynamic focusing system in the optical path; the galvanometer scanning system is behind the uniform light system, and the industrial personal computer is connected with the laser control D/A output card for controlling the laser control D/A output card; and the laser control D/A output card is connected with the laser device, the dynamic focusing system and the galvanometer scanning system correspondingly. The scanning width of the optical path design control system is large, the energy of the processing beam is uniform, so that the laser etching machine produces a higher yield, and the processing range is larger.

Description

technical field [0001] The invention relates to the technical field of laser etching, in particular to an optical path design control system of a laser etching machine, and also relates to a control method of the optical path design control system of a laser etching machine. Background technique [0002] With the popularity of IPHONE, small and medium-sized electronic products such as mobile phones, GPRS, digital cameras, and IPADs have begun to use touch screens as graphic display terminals in large numbers. These electronic products require a large number of touch screen products. Laser etching technology uses fiber laser light to be focused into a spot of 0.01mm or smaller after passing through a set of optical systems. The focused spot is irradiated on the material, and the material begins to melt and vaporize. As the material to be processed moves, the laser beam etches the conductive lines on the material according to the control of the PC, realizing the processing an...
