Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", etc. is based on the orientation or positional relationship shown in the drawings.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0032] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the connection inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. In addition, in the description of the present utility model, unless otherwise stated, the meaning of "a plurality of" is two or more.

[0034] In this embodiment, by forming a closed-loop control chain with the adjustment mechanism, the detector, and the controller, during the welding process of the tab, after the welding head 1 completes the welding, the welding condition of the welding point is observed through the detector, and thus the welding condition is converted into a detection signal and transmitted to the controller. After receiving the signal, the controller makes a judgment.
