Vorrichtung zur optischen Kontrolle einer mit einem Typenrad in ein Werkstück eingebrachten Prägemarkierung mittels einer Kamera

摘要

In a device for optically controlling by means of a camera (11) a mark stamped on a workpiece (2) by means of a type wheel (3), the camera is oriented towards one point of the type wheel (3) located at a defined distance from the stamping site (13). This point of the type wheel is located before, during and/or after the stamping process in the field of vision of the camera (11). According to this process, the stamping process is at first carried out. The stamping point (13) of the type wheel (3) can itself be brought before and/or after the stamping process into the field of vision of the camera and a defect warning is given when the observed point of the type wheel presents an anomaly.
