Poka-Yoke和Jidoka在线检测中的应用

摘要

Poka-yoke prevents defects from being made. Jidoka prevents defects from being passed on to the next step in the process. Applying these two to the online detection can effectively control the quality of products. The thesis introduces the basic concept, the concrete application steps and also the main online detection device type of Poka-Yoke and Jidoka. The detail method of using Poka-Yoke and Jidoka in online detection is explained by the connection screw detecting case which also introduces the process failure mode and effects analysis PFMEA. The design of Poka-Yoke in online detection is illustrated by the case of the limit mechanism. The combination of Poka-Yoke and Jidoka with SPC in online detection is also introduced.%Poka-Yoke和Jidoka可以防止缺陷出现，还可避免缺陷进入到下一步工序中，将这两优势运用到在线检测中可以有效控制产品质量。本文介绍了Poka-Yoke和Jidoka的基本概念、具体应用步骤，以及在线检测主要应用的设备类型；并通过检测接线螺钉案例详细介绍了PFMEA失效模式分析，说明了在线检测中应用Poka-Yoke和Jidoka的方法，通过限位机构案例说明了在过程检测中应用Poka-Yoke的设计方法，还介绍了在线检测中Poka-Yoke和Jidoka与SPC的结合应用。
