[0059] At present, there is a welding process between the pole tab and the adapter in the processing of batteries, and ultrasonic welding is usually used between the pole tab and the adapter. However, when ultrasonic welding is performed between the pole tab and the adapter in traditional technology, the pole tab and the adapter are simply fitted together, which makes the adapter have a large space for movement, and there is a risk of redundant adapters, which can easily lead to a decrease in welding yield. In addition, the adapter will vibrate at a high frequency during ultrasonic welding, and the vibration state of the adapter will cause wear to itself and the welding tooling or device.

[0071] Among them, the welding tool referred to here can be understood to include a welding head and a welding seat. When the welding head extends from the first through-hole 11, the welding seat extends from the second through-hole 211; when the welding head extends from the second through-hole 211, the welding seat extends from the first through-hole 11.

[0086] In some embodiments, Figure 7 As shown, a notch is provided at the outer edge of the adapter plate plug-in block 4 , so that the avoidance groove 43 is formed between the adapter plate plug-in block 4 and the second contoured groove 12 through the notch.

[0087] In some embodiments, Figure 7 As shown, the depth of the avoidance groove 43 is less than the thickness of the adapter plate plug-in block 4 .

[0088] In some embodiments, the depth of the avoidance groove 43 is equal to the thickness of the adapter block 4 .

[0089] The avoidance groove 43 can facilitate the removal of the adapter piece block 4 in the second profiling groove 12 , thereby preventing the removal operation of the adapter piece block 4 from affecting the accuracy of the first profiling groove 41 .
