Welding power source power output change and arc welding robot motion closed-loop control method

Abstract

The invention discloses a welding power source power output change and arc welding robot motion closed-loop control method. Welding current setting, welding voltage setting and wire feeding speed setting are all achieved through initialization panel analog quantity input setting or are provided for a welding power source by a robot upper computer controller through looped network or analog quantity IO interface initialization, are subjected to initial distribution through a welding power core processing mechanism, and are output to an electric arc load, and load power is fed back to a power core control unit when changing, the core control unit conducts processing and achieves interactive communication with an industrial arc welding robot controller, and a robot space planning track is controlled coordinately. When space speed of the robot changes, the robot and a power source achieve communication coordinately, the power source can change welding output currents, voltage and a wire feeding speed value according to the change quantity of the robot. The welding power source power output change and arc welding robot motion closed-loop control method can be widely used for the working conditions with complex robot automatic welding, and labor productivity is improved.

Description

technical field [0001] The invention relates to a closed-loop control method for the power output change of a welding power supply and the action of an arc welding robot. Background technique [0002] At present, the world's four major families of robots, such as KUKA, ABB, FUNC, and Yaskawa, do not have their own welding power sources or do not interact with the welding power source for closed-loop control. As a result, the welding power source and the industrial arc welding robot execute their own system instructions. Welding industrial robots do not really give full play to their advantages. Whenever there is a certain space outside or changes that affect the welding surface, it is necessary to reprogram the teaching and repeatedly adjust the welding process, which wastes a lot of manpower and cannot guarantee product consistency. Contents of the invention [0003] The purpose of the present invention is to provide a kind of welding power output change and arc welding r...
