Welding robot with automatic correction function and welding method employing same

Abstract

The invention belongs to the field of welding and relates to a welding robot with an automatic correction function and a welding method employing the same. An industrial computer is connected with both a robot controller and an industrial camera; the robot controller is connected with a robot and a welding power supply; the welding power supply is connected with a welding torch; the industrial camera and the welding torch are fixed at the tail end of an arm of the robot; a shooting plane of the industrial camera is perpendicular to the welding torch; a work platform is arranged correspondingly. The method includes the steps: the robot is started to demonstrate a template workpiece, shooting is performed in two characteristic regions to determine a spatial position of the workpiece, the industrial camera transmits images of the characteristic regions to the industrial computer, the robot automatically corrects a deviation of an original demonstration path through an image processing technique and software algorithms. The welding robot is simple to operate and widely applicable; by the application of the welding robot in batch welding operations, repeated demonstrations can be effectively avoided, and work efficiency is improved.

Description

technical field [0001] The invention relates to a welding robot system and method with autonomous deviation correction capability, which are suitable for the field of robot welding. Background technique [0002] Welding is an important part of industrial production. The welding process will produce strong light, radiation, smoke and other pollution, which is harmful to the human body. It is the development trend of the welding industry to replace manual labor with automated equipment. Robot is a kind of automation equipment. It has strong flexibility and high precision. It can effectively improve work efficiency and reduce labor intensity when used in the field of welding. At present, teaching and reproduction robots are mostly used in the industry. Compared with intelligent robots, this kind of robots are lower in cost. The working process is roughly as follows: first place the workpiece on the working platform; then use the teaching pendant to operate the robot, and in th...
