Top cover screw floating checker system for hard disk
View Patent ↗A system for cover screw float detection. The system includes a drive cradle coupled to a structure. The system also includes a moveable portion coupled to the structure. The system further includes a sensor coupled to said structure. The system additionally includes another sensor coupled to the moveable portion. Spatial separation between the another sensor and the sensor when the moveable portion is oriented in a screw float check position indicates presence of cover screw float in a disk drive disposed in the drive cradle.
1. A system for cover screw float detection, said system comprising:
a disk drive retainer coupled with a top portion of a base structure, said base structure coupled with a housing structure, said disk drive retainer configured to receive a hard disk drive with a leak test valve;
a moveable portion coupled to said top portion of said base structure, said movable portion configured to move vertically with respect to said base structure and with respect to said housing structure;
a sensor for screw float check coupled to a support member coupled with said base structure;
another sensor coupled to said moveable portion, wherein spatial separation between said another sensor and said sensor when said moveable portion is oriented in a screw float check position indicates presence of cover screw float in a disk drive disposed in said drive retainer; and
a leak tester coupled with said moveable portion configured to couple with said leak test valve of said hard disk drive and configured to determine if said hard disk drive is sealed, wherein said leak tester is operable during said screw float check.
2. The system as recited in claim 1 further comprising:
a plurality of drive bits coupled with said moveable portion, wherein each drive bit is configured to engage an associated cover screw of said disk drive while said moveable portion is in said screw float check position.
3. The system as recited in claim 1 further comprising:
a resistive mechanism coupled with said base structure and configured to contact said moveable portion and provide movement resistance when each drive bit in a plurality of drive bits engages each associated cover screw in a plurality of cover screws.
4. The system as recited in claim 1 further comprising:
a cover screw float indicator for indicating when a threshold spatial distance between said sensor and said another sensor is not achieved.
5. The system as recited in claim 1 further comprising:
a cover screw non-float indicator for indicating when a threshold spatial distance between said sensor and said another sensor is achieved.
6. A method for cover screw float detection comprising:
receiving a disk drive with a leak test valve in a drive retainer, said drive retainer coupled with a top portion of a base structure, said base structure coupled with a housing structure;
orienting a moveable portion coupled with said top portion of said base structure to a screw float check position, said moveable portion configured to move vertically with respect to said base portion and with respect to said housing structure;
engaging a drive bit with an associated cover screw of said hard drive, said drive bit of a plurality of drive bits, said plurality of drive bits coupled with said moveable portion; and
determining the spatial separation between a sensor for screw float check coupled with a support member coupled with said structure and another sensor coupled with said moveable portion when said moveable portion is in said screw float check position; and
engaging a leak tester coupled with said movable portion with said leak test valve of said hard disk drive and determining if said hard disk drive is sealed, wherein said leak detector is operable during said screw float check.
7. The method as recited in claim 6 wherein said receiving further comprises:
removably affixing said disk drive in said drive retainer.
8. The method as recited in claim 6 further comprising:
generating a resistive force against said moveable portion when said moveable portion is oriented in said screw float check position.
9. The method as recited in claim 6 further comprising:
comparing said spatial separation with a threshold spatial separation.
10. The method as recited in claim 9 further comprising;
indicating presence of cover screw float when said threshold spatial separation is not achieved.
11. The method as recited in claim 9 further comprising:
indicating absence of cover screw float when said threshold spatial separation is achieved.
12. The method as recited in claim 10 further comprising:
applying a vacuum to leak test valve of said disk drive, said applying a vacuum for leak testing said disk drive.
