Double Picker Component-Feeding

       This disclosure describes the double picker system that is
used on a robotic tool.  This tool can insert various form (SIP, DIP,
IBM modules) into printed circuit cards.

      Referring to the figure, the double picker assembly is the end
of the arm tool of the feeding system. incorporates dual pneumatic
grippers 6 (or vacuum chucks) two roller cam followers 9 mounted on
linear actuators, well as the interface housing 8 for the tool
adapter. devices allow the system to reach into a tube holder actuate
the tube-holder escapement lever, and pick part to be delivered to
the robot.  The tool adapter for quick interchange of picker
assemblies.

      In its current form, the picker system consists of two pickers
for a given component type.  The following of dual pickers are used:
        IBM modules:  dual vacuum pickers with dual
        compliance sensors and vacuum sensors
        DIPs:  dual vacuum pickers with dual compliance
        sensors and vacuum sensors
        SIPs:  dual grippers with compliance sensors and
        part presence sensors

      The feeder system has many feeders, two test blocks, and
registration block to transfer the part out of the feeder functions
exist but are not relevant to this  The two test blocks are called
test block 1 test block 2.  For a given type of dual picker, the is:
        Current state = part n-1 is in test block m.
        Picker 2-m picks part n out of its fee...
