真空过渡仓闸门结构设计及其锁紧密封性能分析

Structural Design and Performance Analysis for Locking and Sealing of the Vacuum Transition Gate

以动力锂电池生产工艺的真空连续生产线为背景,介绍了真空过渡仓闸门的基本结构,主要包括门体、启闭机构、锁紧机构。闸门的密封由密封结构、锁紧机构共同实现,因此有必要对二者进行关联分析,使得仿真边界条件趋近实际工况。由锁紧机构ADAMS运动仿真得到密封条最大压缩形变;应用ANSYS接触分析,模拟密封过程中密封条截面形变;再次应用ANSYS接触分析,改善锁紧点数量和加强筋设置数量改善密封板和密封条的形变,对4种不同工况下的形变进行模拟,最终得到优化的密封结构,从而保证动力电池在该真空连续线的生产质量。

Based on the vacuum continuous production line of power lithium battery production process, the paper introduces the basic structure of the vacuum transition gate, including the door body, the opening and closing mechanism, the locking mechanism. The sealing of the gate is implemented by the sealing structure and the locking mechanism, therefore, it is necessary to conduct the relevancy analysis of the two, making the simulation boundary conditions approach the actual working conditions. By ADAMS rigid motion simulation of the locking process we get the sealing strip maximum compression. Through ANSYS contact analysis, we simulate the deformation of sealing strip section in the process of simulation and strain in the sealing process, set the locking points and ribs based on the above results to improve the sealing effect. At the end, we obtain the optimized sealing structure by simulating the deformation of 4 under different working conditions. Thereby, the production quality of the power battery in the vacuum continuous line will be assured.
