Design of Welding Robot Control System based on Visual Recognition Technology

Abstract

The level of industrial automation has gradually improved in recent years. Various industries gradually realize automatic welding through the combination of robot system and field equipment. To overcome the defects of traditional welding process, such as high labor costs, low safety, low welding efficiency, and unstable welding quality, a welding robot control system based on visual recognition technology is designed. The system includes three modules, namely visual module, control module and execution module. By Combining visual recognition technology, through the weld image feature measurement and processing method, the system can achieve functions such as weld image acquisition and recognition, weld feature point extraction, welding robot motion trajectory planning, and welding motion control. The system can make the welding quality and efficiency higher and is an automatic innovation of industrial welding technology.
