基于PLC控制器的气动机械手设计

Design of Pneumatic Manipulator Based on PLC

在工业生产中,机械手能够代替人手完成分拣、搬运、装卸等工作,不但减轻了工人的劳动强度,还提高了企业的自动化水平和生产效率。设计了基于PLC控制器的气动机械手,包括方案设计、气动系统设计、控制系统设计和程序设计,以PLC为控制核心,利用气压传动技术驱动机械手臂完成抓取和放置零件的动作,利用电机驱动机械手完成搬运的动作。通过样机的试制和系统的调试运行,表明气动机械手的设计方案是可行的,控制系统是稳定可靠的。

Manipulator can replace the staff to complete the manual sorting,transport,loading and unloading,etc.,in industrial production. It has not only reduced the labor intensity of workers,but also improved the level of automation and production efficiency of enterprises. The pneumatic manipulator based on programmable logical controller（ PLC） is designed,including the scheme design,the pneumatic system design,the control system design and the program design. The PLC was taken as the control core,using pneumatic transmission technology to drive the manipulator arm to complete the action of grasping and placing parts,using motor-driven technology to drive the manipulator to complete the handling action. Through the trial production of the prototype and the debugging of the system,it shows that the scheme is feasible,and the system is stable and reliable.
