摘要
变截面密封介质SEAL膜层合是燃料电池膜电极组件(MEA)制备的重要工序,针对膜电极SEAL膜层合中两侧密封薄膜切口对齐的工艺要求,以无轴同步传动技术为基础,提出一种具有误差补偿功能的主从式多辊同步控制方案。为更好地保证薄膜传输的同步性,该方案根据密封薄膜分布有均匀切口的特点实现了全闭环的位置同步误差补偿。实验结果表明,此种控制策略可以有效地降低薄膜传输过程中的位置同步误差,以实现薄膜输送的精确位置同步,满足相应的工艺要求。
The SEAL film laminating is an important process for manufacturing MEA（Membrane Electrode Assembly）,and for the sealing film cut-aligned process requirement in the SEAL film laminating,a master-slave synchronization control scheme based on the shaftless drive was presented.To ensure the synchronization of film transmission,the scheme formed a closed loop system with synchronization error compensation on the basis of the characteristics of uniform incision on the film surface.The experimental data testified that the control strategy can effectively reduce the position synchronization error,achieve the precise synchronous position for transferring film and fulfill the process requirements.
