Abstract

Described is a manual unclamping tool for hard disk drives that provides an anti-rotational device to hold the disks during disassembly. The tool nut removal without damaging the disks, eliminates operator lifting and through the use of a vacuum scavenger helps to keep the disks and the drive unit from being contaminated.

Manual Unclamping Tool for Hard Disk Drives

       Described is a manual unclamping tool for hard disk
drives that provides an anti-rotational device to hold the disks
during disassembly.  The tool nut removal without damaging the disks,
eliminates operator lifting and through the use of a vacuum scavenger
helps to keep the disks and the drive unit from being contaminated.

      Fig. 1 shows hard drive assembly (HDA) 1 requiring disassembly
being loaded onto cart 2.  Cart 2 is used to wheel HDA 1 to the
manual unclamping tool housing unit shown in Figs. 2a and 2b.  Fig.
2a shows the front view of the unclamping tool housing unit and Fig.
2b shows a side view of the hydraulic mechanism.

      Cart 2 (Fig. 1) is docked into position so that rails 3 can be
inserted onto rollers 4.  HDA 1 is then lowered by means of a cam
(not shown) onto press assembly 7 (Figs. 2a and 2b) and cart 2 is
withdrawn.  HDA 1, containing the disks to be disassembled, is spun
under operator control until HDA 1 is engaged to press assembly 7 by
means of anti- rotation device 5.  Anti-rotation device 5 is designed
to prevent the disks mounted in HDA 1 from spinning during the
removal of nut 6. When HDA 1 is engaged onto anti-rotation device 5,
HDA 1 raises to the position of beam 8.  Beam 8 is then clamped
against HDA 1 so that nut 6 can be manually loosened through an
opening in beam 8.  During the clamping operation of HDA 1, vacuum is
applied at vacuum inlet 9 which removes any particles that may be
generated during the removal of nut 6. When...
