Automatic Load/Unload Device for Printed Circuit Boards

      Disclosed is a device for automatic loading or unloading
of printed circuit boards (or "panels").

      The device is used primarily for loading and unloading of
conveyorized processing equipment.  A selector switch is used to
select either load or unload mode.  The primary components of the
device are conveyor, a pick-up arm, a cart docking mechanism, and the
product transfer cart.

      The product transfer cart made of PVC (Polyvinyl Chloride) is
an integral part of the load/unload device. The PVC cart is designed
to ensure product protection.  The panels are stacked on the cart in
a near vertical position to minimize surface contact and normal force
between the panels.  The cart is made of a non-corrosive material to
eliminate contamination of the panels due to the byproducts of
corrosion.

      The PVC cart docks to the load/unload device as shown in the
figure.  In the unload mode (unloading a piece of process equipment)
the panels enter the load/unload device on the conveyor.  The pick-up
arms pick up the panel from the conveyor with vacuum cups and place
it on the PVC cart. The cart docking mechanism holds the cart and
keeps it positioned correctly.  In the load mode the pick-up arm
picks up a panel from the PVC cart and places it on the conveyor.
The conveyor then transfers the panel to the piece of process
equipment.

      The conveyor portion of the device can be set at a...
