Flexible Low-Cost End-Arm Fabrication of Hard Disk Drive Merge Operation

      A concept that proposes a flexible and low-cost end-arm
fabrication for a merge tool with adjustable cam design shaft is
disclosed.

      Fig. 1 shows the proposed fabricated end-arm which is low-cost,
easy to manufacture, repair, maintain, and with flexibility for
current/future products.  The end-arm is made of three pieces:

1.  The shank arm which is attached to the robot stage shaft and is
    an adapter between the shank and the robot's shaft.  Different
    shanks can be used for different products and can be easily
    attached to the shank arm.

2.  The shank is attached to the shank arm for flexibility with dowel
    pins.

3.  Inserted mold fingers in the shank allow to change these fingers
    easily when they break during the merge operation.

      This concept has been fabricated for a variety of products with
different disk spacing.  The inserted fingers are made of Ultem 7201
which has a high flexuoral modulus.  The Ultem 7201 mold has been
approved for electrostatic discharge (ESD) and a good candidate for
clean room material.

      This concept of end-arm for merge operations has a significant
improvement in cost and flexibility.  The three-piece end-arm is a
new technique to build a low-cost end-arm for the merge operation and
does not require skilled personnel to repair the broken fingers and
long lead time for building these end-arms by...
