Apparatus for separating components of a hard disk drive

1. An apparatus for separating components of a hard disk drive comprising:

a pair of opposing drive rollers configured to contact a hard disk drive housing and move the hard disk drive through a separating station, the separating station defining a base; and

a separating blade mounted on a blade mount, the separating blade and the blade mount resiliently suspended relative to the base such that the separating blade is configured to deflect to a separation point to remove a first hard drive component from a second hard drive component.

2. The apparatus of claim 1 wherein the pair of opposing drive rollers are formed with a plurality of triangular tooth forms terminating in one of a pointed triangular apex or a radiused triangular apex having a form radius in a range of about 0.1 mm to about 0.5 mm configured to either one of deflect or pierce the hard disk drive housing.

3. The apparatus of claim 2 wherein the opposing drive rollers are formed from a plurality of drive roller plates, connected together for concurrent movement.

4. The apparatus of claim 1 wherein the first component is a circuit board and the second component is the hard disk drive, the separating blade is a circuit board separating blade having a slot configured to selectively remove the circuit board from the hard disk drive and permit a third component connected to the circuit board to remain attached to the hard disk drive and the separating point is a region between the circuit board and the hard disk dive housing.

5. The apparatus of claim 4 wherein the third component is a disk drive motor and the separating blade defines a leading edge of the slot that is offset from a leading edge of the blade such that the slot leading edge separates the circuit board from the disk drive motor, the separating blade leading edge defining a rake angle that contacts the circuit board.

6. The apparatus of claim 5 wherein the offset is in a range of about 2 mm to about 20 mm and the rake angle is in a range of about 10 degrees to about 40 degrees.

7. The apparatus of claim 1 wherein the separating blade is a lid separating blade adapted to selectively remove a hard disk drive lid from the hard disk drive housing, wherein the lid separating blade includes a wedge having tapered beveled sides and a forward beveled side defining a blade edge, the separating blade being movable relative to 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 contact between the separating blade and the seam causes the hard disk drive lid to bend and the tapered beveled sides guiding lid edges of the hard disk drive lid to draw inwardly shearing connecting fasteners to separate the hard disk drive lid from the hard disk drive housing.

8. The apparatus of claim 1 wherein the blade mount is an adjustable blade mount having a mounting base and a blade mount receiver, the blade mount receiver and the mounting base including mating channels and projections configured to permit adjustment of the separating blade in a first direction and constrain the blade in a second direction against impact forces with the first hard drive component or the second hard drive component.

9. The apparatus of claim 8 wherein the first component is the hard disk drive housing and the second component is a circuit board.

10. The apparatus of claim 8 wherein the first direction is a height of the separating blade relative to the base, and a jack screw is disposed between a blade support that is connected to the separating blade and the mounting base to adjust the separating blade height.

11. The apparatus of claim 10 wherein the blade mount receiver includes at least one support lock to fix the blade mount receiver relative to the mounting base.

12. The apparatus of claim 10 wherein the jack screw engages a partial bore having threads formed in the blade support and the mounting base includes a jack screw retaining bore that permits the jack screw to rotate relative to the mounting base and axially retained relative to the mounting base.
