针对燃料电池膜电极组件中气体扩散层与催化剂层的贴片工艺，提出了一种具有自动纠偏功能的贴片方案。首先，针对贴片工艺给定机械结构，该结构为具有真空吸附功能的多自由度机械手。然后，采用机器视觉技术获得气体扩散层与催化剂层的位置信息，分析影响贴片精度的原因，并针对该机械结构提出了相应的贴片算法。最后，控制各轴电动机的运动实现精确层合。实验结果表明，该方案的精度符合要求，并具有良好的稳定性和可重复性。

According to the placement processes for gas diffusion layer and the catalyst layer in the fuel cell membrane electrode assembly,gives a placement scheme with automatic deviation-correcting function .At first,a mechanical unit with multi degrees of freedom was given .This unit was a manipulator using vacuum adsorption technology .Then a fusion estimation algorithm based on pseudo-omnidirectional vision for autonomous mobile robot self-motion was proposed .Then the IPC obtained the location informa-tion of the gas diffusion layer and the catalyst layer using machine vision technology .In addition,the reason for affecting the placement precision was analyzed and the solution of this problem was put forward .At last,the IPC controlled the motor moving to paste accurately .Experimental results show that this automatic correction scheme not only has high placement precision but also has the good stability and reproducibility .
