[0002] In the process of power battery module welding, in order to ensure the effect of laser welding and prevent the occurrence of cold welding, it is necessary to use a copper nozzle to press the bar and the pole. The copper nozzle applies pressure while the laser passes through the inner hole of the copper nozzle to achieve the ideal welding effect. At present, in the power battery module bus welding production line, the copper nozzles are all fixed on the pressure plate in an integrated manner, and the pressure plate is a whole plate, which makes it difficult to weld a single product. When a new product needs to be produced, the entire pressure plate needs to be completely removed, which has high manpower and material costs.

[0003] In order to solve the problems existing in the prior art, technicians in this field have made many efforts. For example, Chinese patent application CN 219900661U proposes a copper nozzle quick-change mechanism for busbar welding and a busbar welding device. By adopting a split copper nozzle, and a locking part and an unlocking part, when the pressure plate is pressed down and moved, the unlocking part pushes the locking part, so that the locking part flips and the locking part can be separated from the upper body, thereby releasing the lock between the upper body and the lower body, which is beneficial to the rapid replacement of the lower body. However, when replacing batch products, multiple sets of quick-change mechanisms need to be used, and the structure is complicated. Utility Model Content

[0006] Furthermore, the locking structure also includes a moving part and a base; the base is fixed on both sides of the frame, the moving part is slidably connected to the base, and is externally connected to a driving device; the locking part is fixed to the moving part; the locking part is driven to move by the moving part, and cooperates with the limiting part to complete the locking and unlocking actions.

[0007] Furthermore, a positioning piece is fixed on the moving part; a positioning assembly is provided on one side of the moving part; the positioning assembly includes a base and a sensing part; the base is fixed on the frame; the sensing part is fixed on the base, and is used to identify the position of the positioning piece to determine whether the moving part has moved to the specified position.
