Control method in laser cleaning process and laser cleaning control system

Abstract

The invention relates to a control method in the laser cleaning process and a laser cleaning control system, and belongs to the technical field of laser cleaning technology.The method is based on central processing equipment in the laser cleaning control system, and the central processing equipment comprises a laser cleaning machine head and a shooting unit; the method comprises the steps of receiving workpiece size information input by a user; a preliminary cleaning path is generated based on the workpiece size information, and the laser cleaning machine head is controlled to work through the preliminary cleaning path; shooting an image of the surface of the workpiece through a shooting unit, and generating gray image data of the surface of the workpiece based on the shot image; generating a re-cleaning path based on the grayscale image data and a preset grayscale threshold interval; and the laser cleaning machine head is controlled to conduct cleaning operation again according to the secondary cleaning path. And the central processing equipment controls the laser cleaning machine head to perform cleaning operation again according to the re-cleaning path, so that manual detection is not needed, and the workpiece laser cleaning efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of laser cleaning, in particular to a control method in the process of laser cleaning and a laser cleaning control system. Background technique [0002] Laser cleaning is a process in which laser radiation is used to irradiate the surface of the workpiece, so that the pollutants and rust on the surface absorb laser energy and undergo changes such as instant peeling or evaporation, and are finally effectively removed from the substrate. Compared with traditional cleaning methods such as mechanical friction cleaning and chemical corrosion cleaning, laser cleaning is a green and efficient cleaning method with obvious advantages, so it is gradually accepted by the public in industrial production and daily life applications. [0003] Generally speaking, in the process of laser cleaning the workpiece coated with the surface, there may be some residues, so it is necessary to manually inspect the cleaned w...
