  • Methods for evacuating particles from a hard drive component
    Patent number: 8454755
    Abstract: An assembly tool is provided. The assembly tool comprises a body, a first vacuum channel defined within the body, and a first locating pin attached to the body. The first locating pin has a shaft portion arranged within a surrounding portion of the body. The first locating pin is configured to engage a first alignment feature of a hard drive component at a first contact area to align the hard drive component with the assembly tool. The body is configured to couple the first vacuum channel to a vacuum source and to facilitate particle evacuation from the first contact area via the first vacuum channel when a vacuum is applied by the vacuum source.

  • Systems and methods for gripping a component
    Patent number: 8162366
    Abstract: A gripper assembly is provided. The gripper assembly comprises an actuator and a plurality of gripper fingers. The plurality of gripper fingers are slidably mounted on the actuator. The actuator is configured to slide each of the plurality of gripper fingers along a respective radial path perpendicular to a central axis of the gripper assembly. Each of the plurality of gripper fingers comprises a body and a vacuum evacuation path defined within the body. The body is configured to couple the vacuum evacuation path to a vacuum source and to evacuate particles from a grip area of the gripper assembly via the vacuum evacuation path when a vacuum is applied by the vacuum source.
