[0025] Furthermore, in the attached Figure 3In the figure, the clamping and conveying assembly 3 includes a first support plate 31, and a clamping motor 32 is installed at the end of the first support plate 31. The output shaft of the clamping motor 32 is connected to a clamping rod 33 placed inside the first support plate 31.

By adjusting the pressure and heat of the injected gas by PLC, the welding effect of the automobile battery under different pressure and temperature conditions can also be judged.
