Route and Crimp Workstation

      Manually routing and crimping wire harnesses onto U-shaped
channels on the load beams of head suspension assemblies did not
permit reliability control, resultin in a high incidence of rejects.
An automatic route and crimp workstation eliminated this problem.

Disclosed is a workstation used to:

o   route a four-wire harness through U-shaped channels on the load
    beam of a magnetic head suspension assembly, and

o   fix the harness in place by bending and crimping tabs at each end
    of the channel.

      Prior to the implementation of this automatic workstation, a
skilled operator viewing the assembly through a microscope positioned
the harness visually, then used a hand tool to crimp the tabs
manually.  The unreliability of this method resulted in a high rate
of rejected head suspension assemblies due  o wire breakage during
crimping.

      Fig. 1 shows a completed head suspension assembly.  The wiring
harness, consisting of wires 2 and tubes 3, is attached to the
magnetic head 1.  The harness has been routed into front 4 and back 5
channels of the load beam 6 and crimped with tabs 7.  In Fig. 2 the
magnetic head 1, wiring harness 2, and load beam 6 are clamped in a
tooling fixture 8 (used throughout manufacture of the head suspension
assembly), by fixture 9 and lever 10.

      In Fig. 3 the tooling fixture 8 has been mounted in a clamp 11
of the workstation base 12 in preparation for routing and crimpin...
