电池电芯卷绕方法及采用该方法的电池电芯卷绕机
摘要：
本发明提供一种电池电芯卷绕方法，在该方法中，正极片和负极片从卷针的两侧卷绕到卷针上。本发明还提供采用这种电池电芯卷绕方法的电池电芯卷绕机，该卷绕机包括与卷针的转动中心线相对固定、分别用于承载正负极片的第一极片组件和第二极片组件，第一极片组件和第二极片组件分别位于卷针的两侧。该电池电芯卷绕方法及电池电芯卷绕机改变了现有技术卷绕法卷绕时正极片和负极片位于卷针同侧、相互之间上下重叠的位置关系，克服了正、负极片之间的空间较为狭小的不足，提供了实现正负极片自动上料和离子交换膜自动牵引的可能性，避免人手与离子交换膜和正负极片的过多直接接触，有利于提高电芯卷绕质量，提高生产效率。
摘要（英）：

This invention provides a battery core winding method, in which positive and negative pole piece are rolled on to the rolling needle from two sides of the rolling needle. The invention also provides battery core rolling machine including a first polar piece component and the second component fixed relatively to the rotation center line of the rolling needle and is used for bearing positive and negative pole piece respectively, the first polar component and the second polar component are located at both sides of the needle. The cell batteries winding method and battery winding machine changesanode - cathode polar pieces in the same side and overlapped of the needle and overcomes the deficiency of small space between anode - cathode polar pieces and achieves automatic loadingof the anode - cathode polar pieces and automatic traction of ion exchange film.
