Speech Title: Research on Key Technology and Application of Robot Autonomous Intelligent Spraying

Abstract：In order to meet the demands of multi-varieties and variable batch spraying in aerospace and other fields, the United States Advanced Robot Manufacturing Innovation Agency announced in 2021 that the Mobile Autonomous Coating System for Aircraft Maintenance is one of the important trends of American defense manufacturing technology. With the proposal of China Intelligent Manufacturing 2025, the key technologies of robot autonomous intelligent spraying such as autonomously planning spraying trajectory based on 3D vision and autonomously constructing the object model to be sprayed have become the research hotspot of robot application. Our team is focusing on the problem of autonomous and intelligent robot spraying and carried out a series of key technologies such as precision compensation of spraying robot system, autonomous perception of unknown objects, point cloud reconstruction of multi-view objects, autonomous planning of spraying trajectory, motion optimization of spraying system, adaptive tuning of multi-process parameters of paint, construction of spraying robot environment and walking device of spraying robot. The autonomous and intelligent spraying robot system was successfully developed. The system uses industrial manipulators to accurately spray aerospace components without reprogramming, teaching or equipping high-cost fixtures, and the first pass rate was increased by 50 %. The system can obtain higher precision spraying effect than professional spraying personnel. It is suitable for multi-varieties and variable batch spraying. It has attracted high attention from AVIC Harbin Aircraft Industry, Jilin Aircraft Maintenance Factory and Jigang Automobile Maintenance Factory.
