  • Anomally detection machine for fabricated parts formed on a carrier strip and method of use
    Patent number: 5774227
    Abstract: The invention is directed to a machine for detecting anomalies in parts. A strip of parts (10) is transported through a sensor unit having light sources and photodetector pairs (118, 116; 132, 134; 136, 138) to detect pilot holes and the presence and position of parts. At least one of the light sources (136) is directed at an angle to detect out of plane deformations. Simple light sources and photodetectors are used to detect and identity misaligned contacts without the need for complex vision system components.
