    Abstract: A camera is used to take an image of an end surface of a honeycomb structure gripped by a hand. Based on the image, an initial rotation angle of the honeycomb structure around a vertical axis at a reference position where the image has been taken is recognized. An arm turning section is driven to convey the honeycomb structure gripped by the hand from the reference position to above a plugging mask. A rotation angle required to adjust the rotation angle of the honeycomb structure on the plugging mask to a desired final rotation angle is acquired based on the initial rotation angle recognized at the reference position and a rotation angle of the honeycomb structure around the vertical axis associated with the driving of the arm turning section from the reference position to above the plugging mask. The honeycomb structure is rotated based on the required rotation angle.

The two actuated contact pads are disposed on the end effector so that when actuated the contact pads are translated inwards relative to the end effector to grip the substrate and position a center of the substrate to a predetermined location on the end effector irrespective of a dimensional variance of the substrate.

  • Patent number: 6453543
    Abstract: Disclosed is a workpiece conveyor and delivery device for a vacuum processing plant. Workpieces are delivered from one device to another, both devices being located opposite each other and moving in relation to each other. A controllable magnet arrangement is provided on one of the devices. A moveable armature element acts as a holding device for the workpiece on one of the two devices which move in relation to each other, namely the device provided with the magnet arrangement. Magnet arrangement is driven to activate the holding device which can be deactivated for delivery of workpiece.

  • Patent number: 6322119
    Abstract: An improved conveyor system for transporting a microelectronic workpiece within a processing tool is set forth. The conveyor system includes a transport unit slidably guided on a conveyor rail for transporting and manipulating the workpieces. The transport unit includes a vertical member which is connected to a base end of a two section robot arm. The robot arm includes an end effector at a distal end thereof which is actuated to grip a surrounding edge of a workpiece. A first rotary actuator is arranged to rotate the vertical member about its axis to rotate the entire robot arm. A second rotary actuator is positioned to rotate the second section of the robot arm, via a belt, with respect to the first section of the robot arm. A third rotary actuator is arranged to rotate the end effector about its horizontal axis. The third rotary actuator permits the end effector to flip the microelectronic workpiece between a face up and a face down orientation.
