With the development of electronic technology, computer technology, numerical control and robot technology, automatic welding robot has developed rapidly, Since it was used in production in the 1960s, its technology has become increasingly mature. It has the following advantages: stable and improved welding quality, which can reflect the welding quality in the form of numerical value; improved labor productivity; improved labor intensity of workers, which can work in harmful environment; reduced the requirements for workers' operation technology; shortened the preparation period of product upgrading, and reduced the cost We should pay more attention to the equipment investment. Therefore, it has been widely used in all walks of life.
The welding cycle of each solder joint can be greatly reduced, because the opening degree of the welding tongs is precisely controlled by the robot, and the welding tongs can start to close when the robot moves between points; after a point is welded, the welding tongs can be opened while the robot can move, so it is not necessary to wait for the robot to be in place before the welding tongs are closed or the robot can move when the welding tongs are fully opened The opening of the welding tongs can be adjusted according to the condition of the workpiece. As long as there is no collision or interference, the opening can be reduced as much as possible to save the opening of the welding tongs and the opening and closing time of the welding tongs.
When the welding tongs are closed and pressed, not only the pressure can be adjusted, but also the two electrodes are closed gently to reduce the impact deformation and noise. The wire feeding mechanism can be installed on the upper arm of the robot, or placed outside the robot. The hose between the welding gun and the wire feeder is short in the former, which is conducive to maintaining the stability of wire feeding. When the robot sends the welding gun to some positions, the hose will be in a multi bending state, which will seriously affect the quality of wire feeding. Therefore, the installation of wire feeder must consider the problem of ensuring the stability of wire feeding.
