Cognex Vision Test Stands

Fitz-Thors Engineering recently completed an automated custom vision application for a tier-1 automotive supplier. These test stands utilize Cognex Vision Cameras and Vision View Displays to verify the location and color of the screws and plastic clips on the inside of door panels. Machined fixtures ensure the door panel is positioned correctly by the operator. Once the panel is in position, the operator initiates the test by pressing two buttons. The display will alert the operator of a failed part by displaying a red box around the quadrant that failed as well as placing a red circle around the incorrect or missing fastener(s). This visual indication allows the operator to quickly identify why the part has failed. The results are stored in a database, providing tracability in case future defects are found. This system is much more efficient at catching defective parts than a human.
