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.

每个焊点的焊接周期可大幅度降低，因为焊钳的张开程度是由机器人精确控制的，机器人在点与点之间的移动过程、焊钳就可以开始闭合；而焊完一点后，焊钳一边张开，机器人就可以一边位移，不必等机器人到位后焊钳才闭合或焊钳完全张开后机器人再移动；焊钳张开度可以根据工件的情况任意调整，只要不发生碰撞或干涉尽可能减少张开度，以节省焊钳开度，以节省焊钳开合所占的时间。

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.

焊钳闭合加压时，不仅压力大小可以调节，而且在闭合时两电极是轻轻闭合，减少撞击变形和噪声。送丝机构可以装在机器人的上臂上，也可以放在机器人之外，前者焊枪到送丝机之间的软管较短，有利于保持送丝的稳定性，而后者软管校长，当机器人把焊枪送到某些位置，使软管处于多弯曲状态，会严重影响送丝的质量。所以送丝机的安装方式一定要考虑保证送丝稳定性的问题。

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.
