Long-distance metal part surface laser rust removal and corrosion prevention device and method

Abstract

The invention discloses a long-distance metal part surface laser rust removal and corrosion prevention device and method, and belongs to the technical field of metal material rust removal and corrosion prevention application. The long-distance metal part surface laser rust removal and corrosion prevention device comprises a moving mechanism moving to the vicinity of a part needing rust removal according to a set path, a laser device which is used for generating laser required by rust removal and corrosion prevention and a galvanometer and light path system which comprises a dynamic focusing mirror, a laser range finder, a CCD camera, a gas injection device and a galvanometer; the laser range finder measures the distance between the dynamic focusing mirror and the surface of the part; the dynamic focusing mirror adjusts the focal length in real time, so that the power density of the laser on the surface of the part is stable; the CCD camera acquires a picture of the surface of the partand monitors a rust removal and corrosion prevention process in real time; the galvanometer scans the surface of the part through the laser, so that the part is subjected to rust removal and corrosionprevention; and the gas injection device sprays gas to the derusted part, and laser scanning is combined to complete corrosion prevention treatment. The long-distance metal part surface laser rust removal and corrosion prevention device and method achieve long-distance metal part rust removal and corrosion prevention, the maintenance frequency of the metal part is effectively reduced, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of rust removal and anticorrosion application of metal materials, and more specifically relates to a device and method for laser rust removal and anticorrosion on the surface of remote metal parts. Background technique [0002] Metal parts will rust due to long-term exposure to the air. There are countless metal parts scrapped due to metal parts rusting in the world every year, accounting for about 1 / 3 of the total annual metal output, and the direct economic losses caused by it are as high as 70 million U.S. dollars, the direct economic loss caused by metal corrosion in my country accounts for 4% of the gross national product. Therefore, the research on derusting and anticorrosion of metal parts is very important. Some metal parts need to be installed in places that are inconvenient for operators due to their structure, such as high altitude or dangerous environment, etc. The installation position of such m...
