Assembly tool system
View Patent ↗An assembly tool is provided. The assembly tool comprises a body, a first vacuum channel defined within the body, and a first locating pin attached to the body. The first locating pin has a shaft portion arranged within a surrounding portion of the body. The first locating pin is configured to engage a first alignment feature of a hard drive component at a first contact area to align the hard drive component with the assembly tool. The body is configured to couple the first vacuum channel to a vacuum source and to facilitate particle evacuation from the first contact area via the first vacuum channel when a vacuum is applied by the vacuum source.

wherein the body is configured to couple the first vacuum channel to a vacuum source and to facilitate particle evacuation from the first contact area via the first vacuum channel when a vacuum is applied by the vacuum source.
2. The assembly tool of claim 1 , wherein a separation between an inner wall of the surrounding portion of the body and the shaft portion of the first locating pin is between 0.25 millimeters and 1.36 millimeters.
3. The assembly tool of claim 1 , further comprising a fitting mounted to an exhaust port of the first vacuum channel and configured to couple the vacuum source to the exhaust port of the first vacuum channel.
4. The assembly tool of claim 1 , wherein the first vacuum channel defined within the body comprises an intake port oriented towards the first contact area.
5. The assembly tool of claim 4 , wherein a tip of the first locating pin extends distally beyond the intake port of the first vacuum channel.
6. The assembly tool of claim 1 , wherein the assembly tool is a headstack gripper, the hard drive component is a headstack, the first alignment feature is a pivot shaft of the headstack, and the first contact area comprises a pivot shaft surface of the headstack.
7. The assembly tool of claim 6 , wherein the surrounding portion of the body comprises a sleeve.
8. The assembly tool of claim 7 , wherein a separation between an inner wall of the sleeve and the shaft portion of the first locating pin is between 0.39 millimeters and 1.36 millimeters.
9. The assembly tool of claim 7 , wherein the sleeve is configured to surround a tip of the pivot shaft of the headstack when the first locating pin engages the pivot shaft of the headstack.
10. The assembly tool of claim 1 , further comprising:
a second vacuum channel defined within the body; and
a second locating pin attached to the body and having a shaft portion arranged within a second surrounding portion of the body, the second locating pin configured to engage a second alignment feature of the hard drive component at a second contact area to align the hard drive component with the assembly tool,
wherein the body is configured to couple the second vacuum channel to the vacuum source and to facilitate particle evacuation from the second contact area via the second vacuum channel when the vacuum is applied by the vacuum source.
11. The assembly tool of claim 10 , wherein the assembly tool is a top voice-coil magnet (TVCM) gripper, the hard drive component is a TVCM, the first alignment feature is a first hole in the TVCM, and the second alignment feature is a second hole in the TVCM.
12. The assembly tool of claim 10 , wherein the assembly tool is a top voice-coil magnet (TVCM) presenter nest, the hard drive component is a TVCM, the first alignment feature is a first hole in the TVCM, and the second alignment feature is a second hole in the TVCM.
13. The assembly tool of claim 10 , wherein the assembly tool is a breather filter install (BFI) nest, the hard drive component is a top cover of a hard drive, the first alignment feature is a first hole in the top cover, and the second alignment feature is a second hole in the top cover.
14. An assembly tool system configured to engage a hard drive component comprising:
a vacuum source;
a filter; and
an assembly tool comprising:
a body;
a first vacuum channel defined within the body; and
a first locating pin attached to the body and having a shaft portion arranged within a surrounding portion of the body, the first locating pin configured to engage a first alignment feature of a hard drive component at a first contact area to align the hard drive component with the assembly tool,
wherein the assembly tool system is configured to evacuate particles from the first contact area via the first vacuum channel when a vacuum is applied by the vacuum source to the first vacuum channel via the filter, and
wherein the filter is placed between the vacuum source and the first vacuum channel and is configured to capture the particles evacuated from the first contact area.
15. The assembly tool system of claim 14 , wherein a separation between an inner wall of the surrounding portion of the body and the shaft portion of the first locating pin is between 0.25 millimeters and 1.36 millimeters.
16. The assembly tool system of claim 14 , further comprising:
a fitting mounted to an exhaust port of the first vacuum channel.
17. The assembly tool system of claim 14 , wherein the first vacuum channel defined within the body comprises an intake port oriented towards the first contact area.
