Applicant: Siemens AG (DE); Mehdianpour Mohammad (DE)Patent number: WO2004068926Publication date: 12 August 2004Title: Assembly head comprising grippers for electrical components
Disclosed is an assembly head comprising a plurality of grippers for electrical components, which are movable vertical to a plane of operation, can be displaced individually, and can be coupled to two lifting drive units that can be actuated independently of each other. Said arrangement makes it possible to perform chronologically overlapping lifting movements on two of the grippers and increase the assembly capacity.
Applicant: Bayer AG (US)Patent number: US6374982Publication date: 23 April 2002Title: Robotics for transporting containers and objects within an automated analytical instrument and service tool for servicing robotics
A robotic arm has a pair of gripper fingers designed to grip a variety of containers, including capped and uncapped test tubes as well as containers having unique gripping means. The fingers each have upper and lower projections separated by a groove, the respective projections facing each other when mounted to grippers on the robotic arm. The projections and groove serve to firmly hold the containers as well as self-align the unique gripping means on initially unaligned containers within the fingers as the fingers close around the containers. The fingers have clearance to avoid contact with caps on capped test tubes. Stops are provided at the top of each finger to engage one another and prevent fully closed fingers from deforming. The robotic arm may be transported along a rail mounted above the instrument and a gripper assembly, having a gripper arm, mounted to the robotic arm may be rotated above the instrument to move the container to various locations within the instrument. Side posts on the instruments have a gap between them that permits the gripper arm to rotate and extend outwards to interface with an adjacent instrument or a lab automation transport line.
Applicant: Showa Ika Kohgyo Co Ltd (JP)Patent number: US6790208Publication date: 14 September 2004Title: Rod gripper
A slider having a rod-pressing portion for pressing a rod into a rod-engaging recess is movably provided on a holder body having the rod-engaging recess. The holder body includes a pressing state holding mechanism for relatively moving the slider with respect to the holder body to hold the rod in a state in which the rod is pressed against the rod- engaging recess by the rod-pressing portion. The pressing state holding mechanism includes a screw rod movably, detachably and threadedly engaged with a screw hole formed in the holder body. A tip end of the screw rod and the slider connected to each other such that they permit rotation of the screw rod with respect to the slider but move integrally with respect to the holder body, and the slider can be attached to and detached from the slider.
Applicant: Jones Robert G. (CA); Criscione Frank J. (US); Winkelmolen Antoine J. H. (US)Patent number: US2004173387Publication date: 9 September 2004Title: Gripper devices
Apparatuses and methods of picking up items from a first location and selectively releasing those items at one of multiple desired second locations are provided in which an item is either pierced, clamped, or stuck to a gripper without using vacuum pressure to maintain the grasp between the item and the pickup device. In several embodiments the items are grasped by piercing probes such as an expandable needle, a barbed needle or a screw. In other embodiments the items are clamped by tweezers or a gear and fingers combination. In a final embodiment, an item is grasped by being frozen to a temperature controllable surface.
Applicant: Taiwan Semiconductor Mfg (TW)Patent number: TW579566Publication date: 11 March 2004Title: Gripper for catching wafer in EBR chamber
A gripper for catching a wafer in edge bevel removing (EBR) chamber is described. The gripper has a mounted base, a rotating base, a plurality of transmitting linkages, a plurality of receiving devices and a driving device. The driving device is used to rotate the rotating base coupled to the mounted base and drive the transmitting linkages to move the receiving devices having a recess thereon for holding an edge of a wafer. Moreover, between the active region of the wafer and the receiving devices has a separation contact to completely remove chemicals on wafer during a edge bevel removing process.
