Abstract

When capping modules in a furnace with a slowly moving belt, the module assemblies must be placed on the belt at predetermined intervals approximately every two minutes. In the past, a timer was set for a period of time at the loading station which would ring to alert the operator. No matter what other task the operator was engaged in, it would be interrupted to load the module assembly onto the belt. This arrangement led to considerable inconvenience, operator errors and generally less than optimal efficiency on the part of the operator. This article discloses a simple apparatus for loading assemblies, particularly semiconductor module assemblies, onto a furnace belt at predetermined intervals.

Universal Furnace Loading Mechanism

       When capping modules in a furnace with a slowly moving
belt, the module assemblies must be placed on the belt at
predetermined intervals approximately every two minutes.  In the
past, a timer was set for a period of time at the loading station
which would ring to alert the operator.  No matter what other task
the operator was engaged in, it would be interrupted to load the
module assembly onto the belt. This arrangement led to considerable
inconvenience, operator errors and generally less than optimal
efficiency on the part of the operator.  This article discloses a
simple apparatus for loading assemblies, particularly semiconductor
module assemblies, onto a furnace belt at predetermined intervals.

      As shown in the figure, the apparatus includes a revolving
turntable on which the module assemblies are placed, an air cylinder
attached to a pusher element which pushes the assemblies onto the
furnace belt and a timer which activates the air cylinder to extend
and retract the pusher.  The pusher element is loosely mounted so
that it will pivot around the air cylinder rod if the turntable
rotates before the air cylinder retracts, thus preventing any damage
to the tool or product.  In this embodiment, the turntable has six
positions for the module assemblies which are defined by the six
adjustable part guides attached to the turntable.  The apparatus can
accommodate a variety of different size assemblies.  In the so...
