Patent number: 6572320Abstract: An automated workpiece processing system has a transfer robot including an end effector having arms which move linearly towards each other to pick up a workpiece. Each arm has two workpiece contactors for engaging the edges of the workpiece. The contactors are positioned equally distant from the workpiece edges. The arms are moved linearly together, while they remain parallel to each other. The contactors contact the edges of the workpiece without causing sliding or displacement of the workpiece. Transfer robot movement or pre-positioning of the end effector is minimized, expediting handling of workpieces within the automated system.Type: GrantFiled: July 16, 2001Date of Patent: June 3, 2003Assignee: Semitool, Inc.Inventor: Jeffry Davis

Patent number: 6547258Abstract: A chuck body has a first surface for fixing to a support body and a second surface opposite to the first surface, and the second surface of the chuck body is provided with a pair of chuck members for chucking a workpiece and a guide rail for guiding an open and close operation of these chuck members. Further, a plurality of stationary holes for fixing the chuck body to the support body is formed at a position overlapping with the chuck members of the guide rail so as to communicate with the first surface, and each of the chuck members is provided with a work hole for inserting a screw into these stationary holes.Type: GrantFiled: October 23, 2001Date of Patent: April 15, 2003Assignee: SMC CorporationInventors: Jiro Mandokoro, Hiroshi Hanne

Patent number: 6543988Abstract: A wafer is carried on a blade supported on robotic arms. A plurality of guide clamps both move the wafer into a desired position on the blade and clamp the wafer in place during transport by the arms. The clamps are reciprocally mounted on the blade and are connected with and driven by a rotatable hub carried on the blade and rotated by the movement of the arms. Both the blade and the clamps include beveled surfaces that guide the wafer into place. The operation of the clamps is controlled by a laser that detects when the wafer is out of place or tilted on the blade.Type: GrantFiled: July 18, 2001Date of Patent: April 8, 2003Assignee: Taiwan Semiconductor Manufacturing Co., LtdInventors: Yi-Li Hsiao, Cheng-Chieh Hung, Yu-Tsung Fu, Weng-Liang Fang

Patent number: 6523875Abstract: 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.Type: GrantFiled: November 22, 2000Date of Patent: February 25, 2003Assignee: Atecs Mannesmann AGInventor: RĂ¼diger Ostholt

Publication number: 20030030294Abstract: The invention relates to a parallel gripper comprising a housing (4) and two adjustable gripper base jaws (10, 12) which are guided in the housing (4) in a jaw guiding recess (8) in a displaceable manner. The base jaws (10, 12) can be moved towards or away from one another by means of a wedge hook gearing (20) that can be adjusted by means of a piston (30) that is guided in said housing. The aim of the invention is to provide a compact parallel gripper for transmitting and receiving great gripper forces or overturning moments. According to the invention, the parallel gripper is configured in such a way that the piston (30) is provided with an oval or essentially rectangular form having rounded edges and that the base jaws (10, 12) are provided with at least two guiding webs (16) on both sides respectively. Said webs are rectangular, wedge-shaped or trapezoidal in the cross-section thereof and extend in the direction of displacement (6).Type: ApplicationFiled: September 13, 2002Publication date: February 13, 2003Inventors: Gerhard Michler, Ralf Winkler

Patent number: 6508497Abstract: An overhead clamp-type gripping device for gripping a load from above, includes a carrier frame which is movable in a vertical direction and has support elements positioned on both sides of a center plane and extending downwards from the carrier frame for movement relative to one another. The support elements have longitudinal guides which define an upwardly open angle with respect to the center plane. Received in the longitudinal guides of the support elements is a gripper unit which includes gripping elements for laterally contacting a load.Type: GrantFiled: January 5, 2000Date of Patent: January 21, 2003Assignee: Mannesmann AGInventor: Klaus Nerger

Patent number: 6505871Abstract: An electrically driven gripper has a housing, a gearmotor attached to the housing, a cam engaged to the gearmotor, a pair of opposing jaws slidingly mounted to the housing, a cam follower secured to one of the jaws and in sliding contact with the cam; and a spring configured to impart a force to the jaws such that the jaws are pulled toward each other. The gearmotor drives the cam to force the jaws to a maximum open position. Continued rotation of the cam allows the spring to pull the jaws closed to grasp an object with the jaws. Sensors mounted to the housing determine whether the jaws are in an open or closed state. A simple circuit on a printed circuit board mounted to the housing is used to control the electric gearmotor.Type: GrantFiled: May 21, 2001Date of Patent: January 14, 2003Assignee: Delaware Capital Formation, Inc.Inventor: Peter Elliot McCormick
