Abstract

A method and apparatus for efficiently dismantling hard disk drives, including a holder assembly to clamp a hard disk drive, a scanner that reads identification information of the hard disk drive. A chain conveyor belt indexes the hard disk drive to a position at which a logic board of the hard disk drive is peeled off and dropped into a bin, and to a position at which a lid of the hard disk drive is separated from a housing by way of a wedge, and indexes to a punch position at which magnets are punched in a direction from the logic board side of the hard disk drive. By separating and disposing the logic board and the lid, each hard disk drive is efficiently and securely dismantled.

Claims (16)

1. An apparatus for separating a hard disk drive lid from a hard disk drive housing of an assembled hard disk drive comprising:

a track for supporting and conveying the assembled hard disk drive to a lid separating station; and

a shear blade mounted at the lid separating station and adapted to selectively remove the hard disk drive lid from the hard disk drive housing, wherein the shear blade includes a wedge having tapered beveled sides and a forward beveled side defining a blade edge, the shear blade suspended for movement relative to the track to align a leading edge portion of the forward beveled side with a seam defining an interface between the hard disk drive lid and the hard disk drive housing, wherein the shear blade causes the hard disk drive lid to bend approximately at its center as the leading edge portion of the forward beveled side enters the seam, the forward beveled side initiating bending of the lid away from the hard disk drive housing and the tapered beveled sides guiding lid edges of the hard disk drive lid to draw inwardly, the hard disk drive lid shearing connecting fasteners to separate the hard disk drive lid from the hard disk drive housing.

2. The apparatus of claim 1 wherein the shear blade is resiliently suspended such that the leading edge of the forward beveled side is permitted to move relatively between an upper surface of the hard disk drive lid and the hard disk drive housing to enter the seam.

3. The apparatus of claim 2 wherein the shear blade is resiliently suspended by a spring configured to compensate for variations in the location of the seam by permitting the wedge to float relative to the track to facilitate the leading edge to align with the seam.

4. The apparatus of claim 1 wherein the leading edge of the forward beveled side is approximately one-third of a width of the wedge.

5. The apparatus of claim 4 wherein the tapered beveled sides are generally equal in length on opposite sides of the forward beveled side.

6. The apparatus of claim 5 wherein the tapered beveled sides form a sharp intersection with the forward beveled side.

7. The apparatus of claim 5 wherein the tapered beveled sides form a rounded intersection with the forward beveled side.

8. An apparatus for separating a hard disk drive lid from a hard disk drive housing of an assembled hard disk drive comprising:

a track for supporting and conveying the assembled hard disk drive to a lid separating station; and

a shear blade mounted at the lid separating station and adapted to selectively remove the hard disk drive lid from the hard disk drive housing, wherein the shear blade includes a wedge having tapered beveled sides and a forward beveled side defining a blade edge, the shear blade resiliently suspended for movement relative to the track to align a leading edge portion of the forward beveled side with a seam defining an interface between the hard disk drive lid and the hard disk drive housing such that the leading edge of the forward beveled side is permitted to move relatively between an upper surface of the hard disk drive lid and the hard disk drive housing to enter the seam, wherein the shear blade causes the hard disk drive lid to bend approximately at its center as the leading edge portion of the forward beveled side enters the seam, the shear blade being resiliently suspended by a spring configured to compensate for variations in the location of the seam by permitting the wedge to float relative to the track to facilitate the leading edge to align with the seam, the forward beveled side initiating bending of the lid away from the hard disk drive housing and the tapered beveled sides guiding lid edges of the hard disk drive lid to draw inwardly, the hard disk drive lid shearing connecting fasteners to separate the hard disk drive lid from the hard disk drive housing.

9. The apparatus of claim 8 wherein the leading edge of the forward beveled side is approximately one-third of a width of the wedge.

10. The apparatus of claim 8 wherein the tapered beveled sides are generally equal in length on opposite sides of the forward beveled side.

11. The apparatus of claim 10 wherein the tapered beveled sides form a sharp intersection with the forward beveled side.

12. The apparatus of claim 10 wherein the tapered beveled sides form a rounded intersection with the forward beveled side.
