Automated Tool for Opening Module Carrier

      The primary object of this apparatus is to provide a means for
opening a module carrier and allowing removal of a plastic lead chip
carrier (PLCC) having "J" leads from the carrier for packaging in a
tape reel for shipment.

      An automated tool, shown in the figure, is the alternative to
manual tooling and hand operation which is time consuming and damage
prone. The machine 10 singulates modules in carriers as they leave a
handling tube (not shown) located in a tube holder at input station
11. One module carrier at a time, under control of cylinder 12,
slides down track 13 (inclined at 45 degrees) and into opening
station 14. Sensors 15 and 16 monitor the positioning of the module
carrier at opening station 14. When properly located by cylinder 17,
cylinder arms 18 and 19 engage snap-acting bistable retaining arms or
clips on the module carrier. The clips are moved to their "open"
position allowing module removal. Following removal of the module
from the carrier, the carrier drops into a receptacle under opening
station 14 and another module carrier is released from the handling
tube into the opening station 14 to await module removal after the
module retaining clips are opened.
