The invention discloses a welding robot system which mainly comprises a welding robot, a servo welding gun fixedly connected with the welding robot, and a welding controller which is electrically connected with the welding robot for communication, wherein the welding robot controls the servo welding gun to be started for welding; when reaching a workpiece welding position, the welding robot controls the servo welding gun to be pressurized and sends a welding starting signal and a welding parameter signal to the welding controller; and the welding controller receives the welding starting signal and the welding parameter signal which are sent by the welding robot, provides welding current for the welding robot and the servo welding gun and sets a power-on time, sends a pressurization starting output signal to the welding robot to inform that the welding robot starts the servo welding gun for welding, and sends a welding finish signal to the welding robot to inform that the welding robot stops the servo welding gun to finish the welding.
Description
technical field [0001] The present invention relates to the technical field of robots, and more particularly relates to a robot welding system. Background technique [0002] With the development of the automobile industry, the degree of automation is getting higher and higher, and the body welding of automobile factories mostly uses robot automatic welding. At present, the mature practices in the world are: the first is KUKA robot + RIO servo welding gun + Bosch welding controller (European system), the second is Japanese robot + Ohara servo welding gun + NADEX welding controller (Japanese), European Departmental automobile factories mostly adopt the first method, and Japanese automobile factories mostly adopt the second method. But we all know that on the basis of ensuring welding quality and equipment performance, European servo welding guns and welding controllers are expensive, while Japanese robots are expensive, which leads to high investment costs for the common prac...
