Abstract

The invention discloses a laser cleaning control method and system based on LIBS technology online monitoring, and relates to the technical field of laser cleaning, the laser cleaning control system is researched and developed for achieving the laser cleaning control method, and the laser cleaning control system comprises a mainframe box, a laser cleaning system and an LIBS online monitoring system; the mainframe box is used for bearing the laser cleaning system and the LIBS online monitoring system, and the LIBS online monitoring system is used for collecting and monitoring plasma signals in the cleaning process of the laser cleaning system. According to the laser cleaning control method and system based on LIBS technology on-line monitoring, the dirt cleaning effect and cleaning efficiency of the surface of a cleaned target are greatly improved, on-line monitoring of the laser process is achieved, the laser cleaning process is more automatic, protection on a cleaned target base body is better improved, and the laser cleaning quality is improved. And the service life of the base body is further prolonged.

Description

technical field [0001] The invention belongs to the technical field of laser cleaning, and in particular relates to a laser cleaning control method and a control system based on online monitoring of LIBS technology. Background technique [0002] Industrial production equipment, pipelines, workshops, buildings, raw materials, products or semi-finished products, etc., will be subjected to physical, chemical or biological effects in the process of contact with the atmosphere, environment, production raw materials, media, products, mechanical oil, etc. Its surface residues, deposits and generates various dirt that is harmful to production operation, product quality or human health. The presence of these dirt affects the normal operation of production, affects material performance and equipment life, increases production energy consumption and costs, reduces product quality, and causes hazards of various accidents. Traditional cleaning methods include chemical cleaning, dry ice ...
