Hard Disk Mechanical Pickup Tool for Spindle Use

A tool picks disks up out of cassette containers by using the spring loaded block 1 as a push lever. Disk is held in place on spindles and the tool pulls it on/off using the block as a snap-on/off lever. Note that all disk contact points are on its chamfer edge.

Tool 1, which is either mounted to a robot or is a manual tool, has 'v' grooves in dowels 2. These dowels are in both the end of the tool and in block 3, for pickup on the o.d. chamfered edge. Block 3 is sprung by springs 4 for the snap- in features. The tool is inserted into the cassette and the 'v' grooved dowels in block 3 rest on the top chamfered edge of the disk while the end dowels 2 hook under on the bottom side of the disk. The disk is then lifted out of the cassette. For reinsertion the opposite is done.

For spindle use, the tool puts the disk on the spindle, supporting it while it gets clamped. Once clamped, the tool snaps off by pulling away from the disk. Block 3 works as the snap-on/off component. Again, the opposite is performed while retrieving the disk.

Note that this tool never touches a disk's surface during either operation. Only the chamfered edge of the disk is used for pickup and positioning.
