本申请还提供了一种吸气式卷绕方法，通过具有吸气功能的吸气式卷针将需要卷绕的基材吸附住并进行卷绕工作。
在实际实施本申请时，位于第一工位上的吸气式卷针1通过其外侧的气孔13将电芯基材100吸附住，基材100被吸附住后，对应的卷针驱动电机31通过第一同步带43、第一输出同步轮41、第一输入同步轮42、传动套筒24、第二同步带46、第二输出同步轮44及第二输入同步轮45带动安装轴套筒102及卷针安装轴101、吸气式卷针1转动，实现电芯卷绕功能。
本实施例中，卷绕机构设置有三个吸气式卷针1，当位于第一工位处的吸气式卷针1完成卷绕后，在转塔旋转驱动电机32、主动齿轮61及从动齿轮62的配合驱动下，完成卷绕工作的吸气式卷针1转动到第二工位处，新的吸气式卷针1转动到第一工位处，转动到位后，通过压辊装置7将基材压向第一工位处新的吸气式卷针1侧壁并被卷针吸附住，同时，在裁切装置8及卷针支撑装置9的配合作用下将基材切断，在起卷的0-5圈内，压辊需同步压紧料线。
