  • Patent number: 6938938
    Abstract: A fluid power operate gripper has a housing, in which a drive space is located, which contains at least two drive pistons connected or able to be connected with a respective gripping element. The drive pistons divide up the drive space into a plurality of actuating chambers, which are subject to an actuating fluid under the control of control means in a controlled mutually matching manner. Since the drive pistons are not mechanically coupled kinematically variable operation is made possible in this manner.

  • Patent number: 6530615
    Abstract: A fluid pressure actuated gripper employed in automated workpiece handling systems. The gripper clampingly grips and transfers workpieces from one station to another. A pair of jaw members are positioned in the gripper device which has a pressure-actuated mechanism, a base plate and removable side plate members. A pair of axially offset cam pin members attached to the end of a piston rod and actuated by the pressure-actuated mechanism is used to open and close the gripper jaw members. Pivot pins or shafts pivotably connect the jaw members to the side plate members.

  • Patent number: 6523875
    Abstract: Apparatus for grasping a load from above or from the side, in particular for use in a manipulator, includes two parallel elongate beams, and two carriers extending in a direction of the elongate beams, with each of the carriers supported by a corresponding one of the elongate beams and guided for displacement longitudinally in the direction of the elongate beams. The carriers are disposed in spaced-apart relationship, when viewed in a longitudinal direction of the carriers, and are movable relative to one another at least over a portion of a longitudinal extension of the carriers. Two confronting grippers are secured to the ends of the carriers and positioned on the outside of the carriers, when viewed in a direction transversely to the carriers and when the carriers are completely moved apart. A primary fluid-operated system is provided for moving the carriers in opposition to one another.

  • Patent number: 6513848
    Abstract: The present invention is directed to a wafer clamping mechanism responsive to fluid pressure to retain wafers on a surface with minimal clamping force. The clamping mechanism houses simple operative elements within a housing proximate the wafer and can utilize existing fluid pressure sources to energize the clamping mechanism. In a first embodiment, the clamping mechanism includes a piston and cylinder to urge a clamping arm against the wafer in response to fluid pressure. In a second embodiment, the clamping mechanism includes a bellows arrangement for urging the clamping finger against the wafer in response to a fluid pressure source. In a third embodiment, the clamping mechanism includes a bladder arrangement wherein a bladder is expanded using fluid pressure to urge the clamping arm against the wafer in response to a fluid pressure source.
