基于PLC的机械手控制系统设计

Design of the control system for manipulator based on PLC

为了进一步提高机械手智能化水平,本文结合PLC、机械手和各类元器件的控制系统从硬件和软件两部分进行了设计。硬件部分包括PLC选型,分配I/O口,确定机械手自由度和驱动方式,软件部分主要由自动和手动控制系统、急停和故障指示等部分组成,根据工艺流程绘制流程图编写控制程序。通过仿真验证了控制系统方案设计的可行性,结果表明设计的机械手可以较好地完成物料搬运工作。该系统的设计能够有效地提高工业生产效率,为工业制造向智能智造的发展提供有力支撑。

In order to improve the intelligence level of manipulator,this article designs a control system that combines PLC,robotic arm,and various components from hardware and software aspects.The hardware part includes PLC selection,allocation of I/O ports,and determination of the degree of freedom and driving mode of the robotic arm,while the software part mainly consists of automatic and manual control systems,emergency stop and fault indication,etc.The control program is written based on the process flow chart drawn.The feasibility of the control system design is verified through simulation,and the results shows that the designed manipulator can effectively complete material handling work.The design of this system can effectively improve industrial production efficiency and provide strong support for the development of industrial manufacturing towards intelligent manufacturing.
