Abstract

Described is a design of a multiple-purpose head/suspension (HSA or head) carrier. This device replaces a conventional vacuum-formed in-process tray, manual handling and racking for part cleaning, and trays for inspection and shipment to the next assembly area. The use of this device minimizes handling of the very fragile head/suspension assemblies (thereby minimizing in-process damage), and it simplifies tooling for part handling.

Integrated Head Carrier

       Described is a design of a multiple-purpose
head/suspension (HSA or head) carrier.  This device replaces a
conventional vacuum-formed in-process tray, manual handling and
racking for part cleaning, and trays for inspection and shipment to
the next assembly area.  The use of this device minimizes handling of
the very fragile head/suspension assemblies (thereby minimizing
in-process damage), and it simplifies tooling for part handling.

      One of the implementations of the design is shown in exploded
isometric view in Fig. 1.  An assembled view of this invention is
shown in Fig. 2.  As can be seen, HSAs assemblies are stored in this
invention on individual pallets which are connected in such a manner
as to form a continuous chain.

      The entire device is assembled with injection-molded plastic or
light metal parts for low-cost, lightweight and compatibility with
cleaning solutions.  The plastic is conductive to allow for
protection of electrostatic discharge (ESD)-sensitive components.  An
open frame supports the entire mechanism and provides for easy access
of cleaning solutions and ultrasonic cleaning waves to the parts.
For shipping or storage, secondary covers, very similar to VHS
cassette protective covers, is snapped onto or over the device.

      This device is used in a vertical orientation.  A head may be
placed into or removed from the device with a simple push and slide
motion using a hand- or robot-hel...
