Abstract
A workpiece transfer apparatus includes a stationary base, an elevation base, first and second arms, a workpiece-holding hand, and a driving mechanism for the hand. The first arm is supported on the elevation base so as to be rotatable about a first vertical axis. The second arm is supported on the distal end of the first arm such that the second arm is rotatable about a second vertical axis. The hand is supported on the distal end of the second arm so as to be rotatable about a third vertical axis. A motor is arranged in the first arm, whereas a transmission is arranged to extend in a region from the interior of the first arm through the interior of the second arm.
