一种锂电池烘烤工艺烤箱的门窗设计与实验

The Design and Experimental Study of a Oven Door and Window for Lithium Battery

针对现有锂电池电芯水分烘干工艺的不足,设计了一种新型电芯烘烤工艺,可通过与锂电池的极片一起入壳并与电池注液工艺相衔接,有效避免电芯运输过程的二次污染。设计了一种电芯在烘烤进程中的进出门窗,通过对门窗的销轴、转臂的位置设计,通过ADAMS软件分析,得到了门窗在关闭与锁紧两工位中门窗的移动路径,经由此路径来完成外界与烘烤罐体内部的隔绝过程,通过相关计算可避免门窗启闭过程中构件的死点位置。经Workbench进行销轴等关键零件在实际工作中的受力分析与实验分析表明,此设计精巧且密封效果优良,结构稳定。也可为类似需要密封的其他设备提供良好的借鉴。

Considering the deficiency of water drying technology for current lithium battery cell,a new type of battery cell baking process is designed.It can be connected to the shell of lithium battery and connected with the process of battery injection so as to efficiently avoid the secondary pollution of transportation process for battery cell.A kind of door and window is designed for battery cell,and the moving path of doors and windows in closed and locked positions is obtained through the design of the position of pin and arm of door and window by ADAMS software analysis.Through this path,the isolation process between the outside and the roasted tank is completed.And the dead point position of the component in the opening and closing of door and window can be avoided by the correlation calculation. The stress analysis and experimental analysis of key parts like the pin shaft of Workbench in actual work show that the design is exquisite,the sealing effect is excellent and the structure is stable.Moreover,it can also provide a good reference for other equipment that needs to be sealed.
