一、气动机械手的控制要求
气动机械手的动作示意图如图1所示，气动机械手的功能是将工件从A处移送到B处。控制要求为：
1、气动机械手的升降和左右移行分别由不同的双线圈电磁阀来实现，电磁阀线圈失电时能保持原来的状态，必须驱动反向的线圈才能反向运动；
2、上升、下降的电磁阀线圈分别为YV2、YV1；右行、左行的电磁阀线圈为YV3、YV4； 3、机械手的夹钳由单线圈电磁阀YV5来实现，线圈通电时夹紧工件，线圈断电时松开工件；
4、机械手的夹钳的松开、夹紧通过延时1.7S实现；
5、机械手的下降、上升、右行、左行的限位由行程开关SQ1、SQ2、SQ3、SQ4来实现；
二、机械手的的操作功能
机械手的操作面板如图2所示。机械手能实现手动、回原位、单步、单周期和连续等五种工作方式。
1、手动工作方式时，用各按钮的点动实现相应的动作；
2、回原位工作方式时，按下“回原位”按钮，则机械手自动返回原位； 3、单步工作方式时，每按下一次启动安钮，机械手向前执行一步； 4、单周期工作方式时，每按下一次启动安钮，机械手只运行一个周期；
5、连续工作方式时，机械手在原位，只要按下启动安钮，机械手就会连续循环工作，直到按下停止安钮；
