  • Patent number: 11878432
    Abstract: A robotic integrated circuit placement system includes a test board comprising a socket for holding an integrated circuit, a tester coupled to the test board, a chip tray having a plurality of slots for storing respective integrated circuits including the integrated circuit, and a robotic arm system. The robotic arm system includes a robotic arm having a stepper motor for controlling a position of an end of the robotic arm, a camera, and a controller coupled to the robotic arm and adapted to operate the robotic arm automatically. The controller performs image processing on images acquired by the camera, and moves the integrated circuit between the chip tray and the socket using the robotic arm in response to the image processing.
    Type: Grant

  • Patent number: 11529742
    Abstract: A robotic arm system includes a robotic arm having at least one stepper motor and operable to move an end of the robotic arm in X-, Y-, and Z-dimensions, a camera attached to the robotic arm, and a controller coupled to the robotic arm and to the camera. During configuration, the controller moves the end of the robotic arm to a reference point to obtain initial reference coordinates and a reference image, and to a target location to obtain initial target coordinates. During operation, the controller moves the robotic arm according to the initial reference coordinates, adjusts a position of the robotic arm to an actual reference location using the camera to determine actual reference coordinates, and moves the robotic arm to an actual target location using the initial target coordinates and a difference between the initial reference coordinates and the actual reference coordinates.
