  • Patent number: 6163950
    Abstract: A self-aligning end effector is mounted to a robot for transferring a magnetic read/write head from a feeder to an assembly fixture. The robot positions the end effector above the head. A hollow needle extends from the end effector adjacent to the head. A vacuum is applied through the needle to draw the head to the end of the needle and the end effector is lifted away from the feeder. As the robot moves the end effector toward the assembly fixture, a nest with an alignment locator is lowered onto the head. The locator has tapered sides for orienting the head in a precise alignment. An upper surface of the head seats against a flat surface when it is aligned. The vacuum holds the head on the end effector throughout this operation. The nest is then withdrawn from the head so that it is again located on the end of the needle. When the end effector is located above the assembly fixture, the head is released into the assembly fixture by turning off the vacuum.

  • Patent number: 6071056
    Abstract: A tray used during the processing and handling of HGAs has a set of locating and support features on both its top and bottom surfaces. Each tray has a perimeter which is designed to engage and be stacked above or below other ones of the trays. When the trays are stacked one on top of another, they nest so that the features on a top side of each of the trays do not interfere with the features on a bottom side of the adjacent trays. Thus, a stack of trays can be turned over and the HGAs that are located in the top sides will drop down and instantly be located in the bottom sides of the trays adjacent to them.

  • Patent number: 5930080
    Abstract: A transducer suspension system for a data storage disk drive device has electrical wires strung along the top surface of the suspension. The wires bend around the distal end of the suspension and are connected to electrical pads on the transducer slider below. The height of the wires is reduced by swiping the wires in a lateral direction using a two-finger member. The swipe operation bends the wires down to reduce the overall height and reduces the stress created by the wires in the electrical pad bonds and allows the slider gimbal the freedom to move.
