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.

每個焊點的焊接周期可大幅度降低，因為焊鉗的張開程度是由機器人精確控制的，機器人在點與點之間的移動過程、焊鉗就可以開始閉合；而焊完一點后，焊鉗一邊張開，機器人就可以一邊位移，不必等機器人到位后焊鉗才閉合或焊鉗完全張開后機器人再移動；焊鉗張開度可以根據(jù)工件的情況任意調整，只要不發(fā)生碰撞或干涉盡可能減少張開度，以節(jié)省焊鉗開度，以節(jié)省焊鉗開合所占的時間。

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.

焊鉗閉合加壓時，不僅壓力大小可以調節(jié)，而且在閉合時兩電極是輕輕閉合，減少撞擊變形和噪聲。送絲機構可以裝在機器人的上臂上，也可以放在機器人之外，前者焊槍到送絲機之間的軟管較短，有利于保持送絲的穩(wěn)定性，而后者軟管校長，當機器人把焊槍送到某些位置，使軟管處于多彎曲狀態(tài)，會嚴重影響送絲的質量。所以送絲機的安裝方式一定要考慮保證送絲穩(wěn)定性的問題。

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.
