Description

Battery cell tab position holding mechanism and battery cell transfer device Technical Field The utility model relates to the technical field of battery production equipment, in particular to a battery cell tab position holding mechanism and a battery cell transferring device. Background In the production process of the battery, the positive electrode and the negative electrode of the battery need to be strictly insulated so as to avoid short circuit caused by internal or external contact. In order to better protect the tab of the battery, an insulating cap is usually installed on the tab of the battery (such as the top of a cylindrical battery or the tab of a square battery) to block the metal parts of the battery from directly contacting the external environment, thereby preventing the risk of short circuit caused by collision, extrusion or foreign matter intrusion. In the related art, the lug is required to be bent before the insulating cap is assembled, so that the lug is Z-shaped, and then the insulating cap is sleeved to complete the assembling of the insulating cap. Then, the battery cell covered with the insulating cap needs to be transported to a welding station for welding. However, because the welding has higher requirements on the position accuracy of the electrode lugs of the battery cells, if the insulating caps fall off or shift in position during the process of transferring the battery cells assembled by the insulating caps to the welding station, the subsequent welding quality can be greatly influenced.
