Shipping comb and ramp for disk drive assembly
View Patent ↗A disk drive under assembly is disclosed that comprises a suspension assembly that includes a head gimbal assembly (HGA) that has a lift tab and a shipping comb that includes a protruding member that extends from the shipping comb and a bearing member that supports the suspension assembly, in which the lift tab extends beyond the bearing member. The disk drive under assembly further comprises a ramp that includes a receiving portion to receive the protruding member as the shipping comb couples with the ramp to transfer the lift tab to the ramp.
1. A disk drive under assembly comprising:
a suspension assembly comprising a head gimbal assembly (HGA) including a lift tab;
a shipping comb comprising a protruding member that extends from the shipping comb and a bearing member supporting the suspension assembly, wherein the lift tab extends beyond the bearing member; and
a ramp including a receiving portion to receive the protruding member as the shipping comb couples with the ramp to transfer the lift tab to the ramp.
2. The disk drive of claim 1 , wherein the protruding member of the shipping comb extends into the receiving portion of the ramp.
3. The disk drive of claim 2 , wherein the receiving portion is shaped to engage the protruding member to vertically align the shipping comb and the ramp.
4. The disk drive of claim 3 , wherein the receiving portion is approximately channel-shaped.
5. The disk drive of claim 1 , wherein the protruding member is approximately pin-shaped.
6. The disk drive of claim 5 , wherein the approximately pin-shaped protruding member extends perpendicularly from the shipping comb.
7. The disk drive of claim 1 , wherein after the lift tab is transferred to the ramp, the shipping comb is removed from the ramp and the HGA.
8. The disk drive of claim 1 , wherein the shipping comb comprises a shipping comb base and the protruding member extends perpendicularly from the shipping comb base.
9. The disk drive of claim 1 , wherein the protruding member is untouched by the lift tab.
10. The disk drive of claim 9 , further comprising a gap between the lift tab and the protruding member.
11. The disk drive of claim 10 , wherein the protruding member engages with the receiving portion while the lift tab engages with the ramp.
12. A method to transfer a head gimbal assembly (HGA) to a ramp comprising:
mounting a shipping comb to a ramp, wherein the shipping comb includes a protruding member that extends from the shipping comb and a bearing member supporting a suspension assembly that includes the HGA including a lift tab; and
transferring the lift tab of the HGA to the ramp, wherein the ramp includes a receiving portion to receive the protruding member as the shipping comb couples with the ramp.
13. The method of claim 12 , further comprising extending the protruding member of the shipping comb into the receiving portion of the ramp.
14. The method of claim 13 , wherein the receiving portion is shaped to engage the protruding member to vertically align the shipping comb and the ramp.
15. The method of claim 14 , wherein the receiving portion is approximately channel-shaped.
16. The method of claim 12 , wherein the protruding member is approximately pin-shaped.
17. The method of claim 16 , wherein the approximately pin-shaped protruding member extends perpendicularly from the shipping comb.
18. The method of claim 12 , further comprising removing the shipping comb from the ramp and the HGA after the lift tab is transferred to the ramp.
19. The method of claim 12 , wherein the shipping comb comprises a shipping comb base and the protruding member extends perpendicularly from the shipping comb base.
20. The method of claim 12 , wherein the protruding member is untouched by the lift tab.
21. The method of claim 20 , wherein a gap is located between the lift tab and the protruding member.
22. The method of claim 21 , further comprising engaging the protruding member within the receiving portion while the lift tab engages with the ramp.
