Patent number: 8016541Abstract: A system is provided for sensing, orienting, and transporting wafers in an automated wafer handling process that reduces the generation of particles and contamination so that the wafer yield is increased. The system includes a robotic arm for moving a wafer from one station to a destination station, and an end-effector connected to an end of the robotic arm for receiving the wafer. The end-effector includes a mechanism for gripping the wafer, a direct drive motor for rotating the wafer gripping mechanism, and at least one sensor for sensing the location and orientation of the wafer. A control processor is provided for calculating the location of the center and the notch of the wafer based on measurements by the sensor(s). Then, the control processor generates an alignment signal for rotating the wafer gripping mechanism so that the wafer is oriented at a predetermined position on the end-effector while the robotic arm is moving to another station.Type: GrantFiled: January 28, 2005Date of Patent: September 13, 2011Assignee: Brooks Automation, Inc.Inventor: Matthew W.

Patent number: 7972252Abstract: An ergonomic tool lifting machine and method particularly useful for manipulating a machine tool or another heavy object. In one embodiment of the invention, the machine tool is a large milling cutter. The ergonomic tool lifting machine generally includes an articulating arm attached at a fixed end to a vertical lift mechanism, and at a free end to a grasping device or tool holder adapted for gripping and retaining an object of interest. When the object is a milling cutter, the ergonomic tool lifting machine may be used to transfer the cutter between a stored position and an installed position in a milling machine. Consequently, the tool holder of this embodiment is preferably able to rotate between a pick-up/drop-off position and an installation/removal position associated with the cutter. In general, the ergonomic tool lift machine allows heavy loads to be accurately moved with very little effort required on the part of an operator.Type: GrantFiled: March 28, 2006Date of Patent: July 5, 2011Assignee: Honda Motor Co., Ltd.Inventor: Freedus McDermitt, Jr.

Patent number: 7955043Abstract: Provided is a substrate transfer apparatus which can perform stable and highly accurate transfer without making a configuration complicated. A substrate transfer apparatus according to the present invention includes a multijoint arm whose one end is arranged on a base and the other end is connected to a hand for supporting a substrate, a linear guide for guiding a rectilinear movement of the hand, and a belt driving mechanism for moving the hand along a guide rail of the linear guide. The substrate transfer apparatus having such a configuration supports a load acting on the hand by the multijoint arm and ensures rectilinear transfer performance of the hand by the linear guide. Therefore, since a special mechanism for passing the substrate through a dead point is not required, the configuration is prevented from becoming complicated. Furthermore, since the load does not directly act on the linear guide, high transfer accuracy can be obtained.Type: GrantFiled: May 28, 2007Date of Patent: June 7, 2011Assignee: Ulvac, Inc.Inventor: Hirotoshi Nakao
