  • Three-dimensionally movable transfer robot
    Patent number: 6655901
    Abstract: A transfer robot includes a machine base, at least one hand for holding a workpiece, a hand moving mechanism for moving the hand horizontally reciprocally at least in an X direction, a first arm pivotally connected to the machine base for rotation about an axis extending in the X direction. The robot further includes an intermediate arm pivotally connected to the first arm for rotation about another axis extending in the X direction, a second arm pivotally connected to the intermediate arm for rotation about a further axis extending in the X direction. The second arm is also connected to the hand moving mechanism which is rotatable about a still another axis extending in the X direction. A driving mechanism is provided for rotating the first arm, the second arm, the intermediate arm and the hand moving mechanism about the respective axes.
