由于采用了一體化焊鉗，焊接變壓器裝在焊鉗后面，所以點焊機器人的變壓器必須盡量小型化。對于容量較小的變壓器可以用50Hz工頻交流，而對于容量較大的變壓器，工業(yè)上已經(jīng)開始采用逆變技術(shù)把50Hz工頻交流變?yōu)?00～700Hz交流，使變壓器的體積減少、減輕。焊接機械手,自動焊接機器人

Due to the use of integrated welding tongs, the welding transformer is installed behind the welding tongs, so the transformer of the spot welding robot must be minimized as much as possible. For transformers with smaller capacity, 50Hz power frequency AC can be used, while for transformers with larger capacity, inverter technology has been adopted in industry to convert 50Hz power frequency AC to 600-700Hz AC, reducing and reducing the volume of the transformer.

變壓后可以直接用600～700Hz交流 電焊接，也可以再進行二次整流，用直流電焊接，焊接參數(shù)由定時器調(diào)節(jié)。目前，新型定時器已經(jīng)微機化，因此機器人控制柜可以直接控制定時器，無需另配接口。點焊機器人的焊鉗，用電伺服點焊鉗，焊鉗的張開和閉合由伺服電機驅(qū)動，碼盤反饋，使焊鉗的張開度可以根據(jù)實際需要任意選定并預(yù)置，而且電極間的壓緊力也可以無級調(diào)節(jié)。焊接機器人,6軸機器人,工業(yè)機器人

After voltage transformation, welding can be directly carried out using 600-700Hz AC power, or secondary rectification can be carried out using DC power welding. The welding parameters are adjusted by a timer. At present, the new type of timer has been computerized, so the robot control cabinet can directly control the timer without the need for additional interfaces. The welding tongs of the spot welding robot use electric servo welding tongs. The opening and closing of the welding tongs are driven by servo motors, and the encoder feedback allows the opening degree of the welding tongs to be selected and preset according to actual needs, and the clamping force between the electrodes can also be infinitely adjusted.

電伺服點焊鉗具有如下優(yōu)點：

The electric servo spot welding pliers have the following advantages:

1、焊鉗張開度可以根據(jù)工件的情況任意調(diào)整，只要不發(fā)生碰撞或干涉，可盡可能減少張開度，以節(jié)省焊鉗開度，節(jié)省焊鉗開合所占的時間。

1. The opening degree of the welding tongs can be adjusted according to the situation of the workpiece. As long as there is no collision or interference, the opening degree can be reduced as much as possible to save the opening degree of the welding tongs and the time required for opening and closing.

2、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。

2. The welding cycle of each welding point can be significantly reduced, because the opening degree of the welding tongs is precisely controlled by the robot. During the robot's movement between points, the welding tongs can start to close; After welding a little bit, the welding tongs can be opened on one side, and the robot can move on the other side. There is no need to wait for the robot to be in place before the welding tongs close or fully open before the robot moves again.

3、焊鉗閉合加壓時，不僅壓力大小可以調(diào)節(jié)，而且在閉合時兩電極是輕輕閉合，可減少撞擊變形和噪聲。焊接機械手,自動焊接機器人

3. When the welding pliers are closed and pressurized, not only can the pressure be adjusted, but also the two electrodes are gently closed during closure, which can reduce impact deformation and noise. Welding robot
