  • Systems and methods for assembly tool calibration verification
    Patent number: 8447430
    Abstract: An assembly tool calibration verification system includes a hard drive component gauge (HDCG), a vision system, a controller, and a gripper assembly. The HDCG includes a first vision detection feature. The vision system is configured to capture an image of the HDCG. The controller is configured to determine a position of the HDCG based on the first vision detection feature in the captured image of the HDCG. The gripper assembly is configured to pick the HDCG from a tray and is positioned for picking the HDCG from the tray based on the determined position of the HDCG. The controller is further configured to generate a calibration verification signal based on at least one of determining the position of the HDCG by the controller and picking the HDCG from the tray by the gripper assembly.
