Pin Insertion

      Disclosed is a method to insert .008 thick L shaped pins into a
preformed press fit slot and adapt the mechanism to an automated
system.

      This invention is accomplished by orienting and packaging the
leads into an in-line staple form and then individually strip, guide
and force each pin into a press fit slot.  The packages are magazines
which are about ten inches long and can be automatically fed into an
automated system.

      The leads are stripped one at a time by a pusher attached to a
linear shaft.  The shaft is attached to a high torque motor using an
eccentric to control travel of the pusher and how far a lead is to be
inserted into the carrier.  After stripping one lead the pusher
retracts, a continuous force spring applies pressure to the stack of
leads, moving the next lead in-line to be inserted.  Through an
indexing unit the lead being inserted is lined up with the slot it is
to be inserted into.  The pusher moves the lead through an enclosed
tunnel guiding it into the slot and the high torque motor applies
enough force to insert the lead into the press fit slot.  The whole
assembly is mounted on an X,Y slide and the unit automatically
indexes to the next slot and the cycle is repeated (Figs. 1 and 2).
