Grasping devices are assembled in the work stations for grasping the reference members and positioning them accurately while temporarily disengaging them from the conveyance devices to accurately position the body supported on the reference members in the station space. The reference members include a grasping device to grasp the body and holding it steadily against them when operated by actuators assembled in the work station.

  • Patent number: 6419071
    Abstract: A lowerator for an assembly system of the type including at least one rail defining a path of travel with respect to at least one workstation, and a conveyor for transporting a work piece along the rail. The conveyor includes a trolley moveable along the rail and a carrier moveable with respect to the trolley. The carrier supports a work piece during movement with respect to the workstation. The carrier is vertically positionable between a raised position and lowered position with respect to the trolley. The lowerator moves the carrier between the raised and lowered positions and cycles a latch for securing the carrier to the trolley when in the raised position. The lowerator includes at least one lifter or actuator defining a path of travel in at least a first direction, wherein the lifter actuates the latch to uncouple the trolley and carrier before moving the carrier into the lowered position at the workstation so that one or more processing operations can be performed on the work piece.

  • Patent number: 6381516
    Abstract: An off-line micro device processing system is provided having a longitudinally extending feeder/processing/buffer system for providing processed micro devices to a pick point. A portable robotic system has a longitudinally extending robotic system body extending parallel to the longitudinally extending feeder/processing/buffer system and a transverse support on the robotic system body transversely positioned relative to the longitudinally extending robotic system body. A pick and place mechanism on the transverse support picks micro devices from the input, transversely moves the micro devices, and places the micro devices on the output system for receiving and storing processed micro devices.
