[Poka-Yoke Example] Poka-Yoke for Visual Inspection in the Inspection Process

Achieving prevention of forgetting visual checks in the inspection process.

We received a request from an automobile manufacturer stating, "We would like to implement a visual inspection process for automotive glass marks to prevent oversight by operators (poka-yoke)." To ensure that the visual check of the glass marks is reliably conducted, we developed a system that "wirelessly transmits work performance when the glass mark is checked with a pen that does not leave ink (when it comes into contact with the glass)." In developing this system, we utilized the mechanism of the Check Pen S while ensuring compatibility with the TW-800 series receivers already in use at the customer's production site, incorporating the following technical innovations: [Details] (1) We will create a dedicated pen that does not leave ink. The tip of the pen will be made of a soft material to prevent scratching the glass upon contact. (2) The dedicated pen will be stored in the pipe of the Check Pen S, and a cap will be added to protect the tip of the dedicated pen. (3) To facilitate the visual inspection work for the operators, the structure will allow the Check Pen S to be suspended from the operator's neck. *For more details, please refer to the PDF document or feel free to contact us.
