  • Publication number: 20250105330
    Abstract: This application relates to the field of battery production equipment technologies, and in particular, to a cutting-off apparatus and battery assembly line production equipment. The cutting-off apparatus at least includes a slitting mechanism and a supporting element. With the provision of a supporting element connected to the slitting mechanism, the supporting element can provide a supporting force acting on a target electrode plate when the slitting mechanism in a cutting-off position is cutting off the separator. Then, when the separator rebounds due to being cut off and impacts the target electrode plate, the target electrode plate can avoid skewness due to the rebound of the separator under the support of the supporting element, thereby alleviating the problem of wrinkles of the electrode plate caused by the separator being cut off during winding of an electrode stack and reducing the risk of defects inside the battery.
