  • Hard disk drive top cover removal
    Patent number: 9275677
    Abstract: A hard disk drive (HDD) top cover removal tool includes a nest assembly, a clamp, a guide plate, and a purge and vacuum assembly (PAVA). The nest assembly secures an HDD and rotates it from a first to a second position. The clamp presses against a top cover of the HDD such that the top cover maintains contact with a hard drive body of the HDD. A hole defined in the guide plate is aligned with a screw location of the top cover and the hard drive body, and receives a screw driver for removing a screw fastening the top cover to the hard drive body. The PAVA purges and evacuates particles from the screw location of the top cover and the hard drive body of the HDD in the second position. The clamp releases the top cover. The PAVA removes the released top cover from the hard drive body.

  • Hard drive assembly tools for evacuating particles
    Patent number: 8356384
    Abstract: A clean and purge tool (CAPT) is provided and includes a nest assembly that stows an open hard disk drive (HDD). The nest assembly is rotated from an upward facing position to a downward facing position to dislodge particles from a media clamp of the HDD. The CAPT also includes a cover hingedly attached to the nest assembly and encloses the HDD. The CAPT also includes a spindle clamp assembly (SCA) mounted on the cover and has a vacuum tube configured to encapsulate the media clamp. The SCA includes an air purge nozzle extending into the vacuum tube. The CAPT dislodges particles from the media clamp when pulses of compressed gas are applied to the media clamp by a compressed gas source via the air purge nozzle and evacuates the particles from the vacuum tube when a vacuum is applied to the vacuum tube by a vacuum source.
