基于PLC的洗衣机轴总成自动压装系统

An Automation System for Pressing Shaft Assembly of Washing Machine Based on PLC

为了提高国内洗衣机离合器企业的自动化程度,通过引入PLC+HMI技术,结合多传感器融合技术,设计了一套洗衣机轴总成的自动化压装设备,并搭建了电控系统。通过设计一体化压装附具,实现一次成型,为变位机的使用提供了条件,压力传感器与位移传感器可实时监控压装效果;针对不同工件设计相应的上料机构,降低了上料工人的劳动强度;通过人机交互界面及自动化程序,实现对接触器、继电器等电气元件的控制。最终设计了试验台,验证了设备的可行性,目前该设备已在现场使用。

To improve the automatization and strengthen the competitive of the domestic enterprises who produce the clutch for washing machine,an automation system for pressing shaft assembly of washing machine is designed based on PLC&HMI,and multisensor fusion system.The positioner is introduced because that the integrated fixture is proposed to contain all elements of the shaft assembly.The pressure transducer and displacement transducer are adopted to monitor the pressure process.With regard to every element,different feeding mechanism is designed and the storing can keep40minutes according to the designed pitch time.Through the friendly man-machine interaction interface,the system can run in two modes:manual operation,automatic operation and the pitch time can keep in9seconds.Finally,the model machine validates the usefulness of the system and it has been employed in the production field.
