Abstract

A fixture was required for a disk-handling tool used on a production line to enable the tool to handle different sizes of disks. In prior art, tool throughput was limited by the ability to handle one disk size at a time. The spread and rotate fixture disclosed herein satisfied this requirement.

Spread and Rotate Fixture

      A fixture was required for a disk-handling tool used on a
production line to enable the tool to handle different sizes of
disks.  In prior art, tool throughput was limited by the ability to
handle one disk size at a time.  The spread and rotate fixture
disclosed herein satisfied this requirement.

      As shown in Fig. 1, disks 1 are picked up from a cassette and
placed on the spread and rotate fixture.  The fixture consists of
connector links 3 which define the pitch or spacing between disks
inside the cassette, and nest links 4 which define the pitch or
spacing between disks on the cartridge.  (Shown in this Figure are
seven 65mm disks.)

      Fig. 2 shows the position of the disks simultaneously spread 5
and rotated 6 halfway (that is, by 45 degrees).

      As shown in Fig. 3, a disk 1 sits inside a disk holder 7, which
is connected to the actuator 8 at pivot point 9.  A motor 10 is
attached to the actuator.

      Fig. 4 shows the actuator connected to the connector link 11.
The spread and rotate fixture travels along the groove 12.  A
10-degree offset between the groove and actuator causes the fixture
to fold when the actuator extends and spread when it retracts.
