Three-dimensional laser washing device

Abstract

The utility model discloses a three-dimensional laser washing device. The three-dimensional laser washing device comprises a pulsed laser with indicating red light and a control system of the same pulsed laser, a beam spread collimation optical system, a two-dimensional optical scanning galvanometer and a controller of the same two-dimensional optical scanning galvanometer, a focusing position regulator and a displacement controller. The focusing position regulator consists of a focusing lens, a filter, a microscopic imaging lens, a CCD (Charge Coupled Device) and a processor, wherein the focusing lens is fixed with the microscopic imaging lens, the indicating red light of the pulsed laser reflects on the sample and images on the CCD (Charge Coupled Device), the microscopic imaging lens moves longitudinally to find a position where the contrast ratio is the highest and the image edge is the clearest, the position is a focus position of the focusing lens, and the three-dimensional laser washing device consists of the two-dimensional scanning galvanometer and the focusing lens. The three-dimensional laser washing device makes full use of the two-dimensional laser washing device which is based on the optical galvanometer scanning system, presetting the surface shape of the washing material is not required before cleaning, thereby having the advantages of being wide in application, simple in structure, good in stability, easy to debug, and the like.

Description

technical field [0001] The invention belongs to the field of laser cleaning, and in particular relates to a three-dimensional laser cleaning device based on an optical two-dimensional scanning vibrating mirror and which can be automatically adjusted according to the surface shape of a material to be cleaned. technical background [0002] Laser cleaning is a new type of green cleaning method, which can clean various types of pollutants on the surface of various materials. It has the advantages of convenient long-distance and automatic operation. At present, laser cleaning devices are basically aimed at planar structures, using optical galvanometer scanning systems to achieve two-dimensional cleaning. The working principle of the optical galvanometer scanning system is to collimate the laser output from the laser and then control the movement in the x-axis and y-axis directions by two scanning galvanometers, and then converge to the material surface by the focusing lens. This...
