Automated welding machining system for non-standard components based on structural light vision

Abstract

The invention provides an automated welding machining system for non-standard components based on structural light vision. The automated welding machining system comprises a weld joint visual detection system, a welding executing system, a communication and control system, a robot controller and a welder controller, wherein the weld joint visual detection system is used for recognizing weld joints, detecting positions, monitoring progress and transmitting images to the communication and control system; the welding executing system is used for executing welding action, and comprises a six-degree-of-freedom industrial robot, a welder and a welding gun; the communication and control system is used for realizing communication and process control, uses an industrial control computer as main control equipment and finishes the functions of displaying a welding process, processing the images, carrying out data operation and sending instructions; the robot controller receives instruction signals from the industrial control computer and controls the joint movement of the six-degree-of-freedom industrial robot so as to adjust the pose of the welding gun; and the welder controller receives the instruction signals from the industrial control computer and controls welding parameters, such as welding current and wire feed speed. The automated welding machining system can accurately detect and recognize features, such as weld joint types, positions and shapes, stably improve the welding machining quality of the non-standard components and greatly increase the production efficiency.
