Description

Battery insulating sheet blanking device Technical Field The utility model relates to the technical field of battery insulating sheet processing equipment, in particular to a battery insulating sheet blanking device. Background The battery insulating sheet can effectively isolate the anode and the cathode of the battery core, prevent the short circuit phenomenon caused by contact, and can also protect the battery from being influenced by environmental factors such as humidity, dust and the like. The battery insulating sheet needs to be punched with specific holes or shapes during processing, and can be used for positioning and assembling to ensure the correct position of the insulating sheet in the battery module. For example, patent publication CN112936436B discloses an insulating sheet blanking device for battery production, which can blanking an insulating sheet. In order to ensure that the material sheet does not shake during blanking, the material sheet is usually pressed by a pressing plate and then blanked by the existing blanking device during blanking. However, the large size of the platen is difficult to be applied to blanking a small area of a material sheet, and if the area of the platen is reduced, it is difficult to install a guide assembly and a spring. Disclosure of utility model The utility model provides a pool insulating sheet blanking device which is suitable for small-area insulating sheets and is convenient for replacing a compacting piece. The battery insulating sheet blanking device comprises a blanking assembly, a positioning assembly and a base, wherein an elastic piece and a guide assembly are arranged between the blanking assembly and the positioning assembly, the blanking assembly drives the positioning assembly to abut against or separate from the base, the positioning assembly comprises a positioning seat, a pressing piece and a locking piece, the positioning seat is provided with a through hole, the through hole is correspondingly arranged with a punch of the blanking assembly, a containing cavity is formed in the through hole, the pressing piece is arranged in the containing cavity and locked or released through the locking piece, the height of the lower end face of the pressing piece is smaller than that of the lower end face of the positioning seat, the pressing piece is provided with a guide hole and a side hole communicated with the guide hole, the guide hole and the punch are coaxially arranged, and the side hole is located on the side face of the pressing piece. In some embodiments, the outer wall of the pressing piece is provided with a notch, and the locking piece is arranged in the positioning seat in a penetrating way and corresponds to the notch. In some embodiments, the positioning seat has a notch portion, and the notch portion is disposed corresponding to the side hole.
