Patent number: 6491330Abstract: An edge-gripping wafer handling apparatus for holding and transporting wafers in a clean room environment is implemented by mounting gripping fingers on a paddle arm adapted to be controlled by a robot. At the free end of the paddle arm, a plurality of fixed fingers is mounted. Each of these fixed fingers includes a notch for gripping the edge of a wafer. A moving finger is mounted close to the fixed end of the paddle arm. The moving finger can be smoothly moved to engage the edge of the wafer and cause the opposite edge of the wafer to engage the fixed fingers. The movement of the moving finger is caused by a bellows flexing a hinge connected to the finger. The flexing hinge is formed as a parallelogram of two stable ends and two flexing arms. The movement of the hinge is smooth and causes no particulate matter to be generated due to rubbing or other friction generating mechanism.Type: GrantFiled: May 3, 2000Date of Patent: December 10, 2002Assignee: Ade CorporationInventors: Anil Mankame, Anthony Florindi, Fredrick Arnold Goodman

Patent number: 6286662Abstract: The invention relates to a clamp (10) for holding sheet-like objects, having a support (12) on which a clamp tongue (20) is fixed. A clamping jaw (32) is stored in a guide slot (30) in the support (12) in such a way that it can move both in and against the direction of closing (S). When the clamping jaw (32) moves from open position (34) in closing direction (S), the clamp end (42) is displaced along the path of movement (46), until it rests against the clamp tongue (20) or an adjacent object. As the clamping jaw (32) continues to move in closing direction (S), the clamp end is driven back from the path of movement (46), and a clamping force for holding the object is formed as a result of the elasticity of the clamping jaw (32).Type: GrantFiled: January 27, 2000Date of Patent: September 11, 2001Assignee: Ferag AGInventor: Jacques Meier

Patent number: 6260901Abstract: A bracket for engagement with an object of a substantially rigid sheet-like material has a V- or U-shaped body portion that is produced from a spring material. The body portion has two shanks, and in each shank there is a recess. Each recess is open to an edge of the shank. The recesses have opposing abutment surfaces, and one of the abutment surfaces is on a flap extending from the shank. One or more tips project from any of the abutment surfaces to establish a point contact with sheet material to hold it. When the opposing abutment surfaces are in line with each other, a look-through region between the abutment surfaces increases when the shanks are moved relative to one another against the spring bias to enable positioning the material therebetween.Type: GrantFiled: June 11, 1999Date of Patent: July 17, 2001Assignee: Torestorps Trad ABInventor: HÃ¥kan Torefors
