ABSTRACT:
The invention of the present document comprises apparatus for receiving and automatically feeding dual-in-line package (DIP) transportation and storage tubes (24) to the singulator (76) of an integrated circuit device handler (20) so that devices (22) in the tubes (24) can be introduced at the singulator (76). The tubes (24) are randomly placed in a hopper (66), and conveyed through an aperture (170) formed in a side wall (172) of the hopper (66). An elevator (74) is provided to raise the tubes (24) to a height at which open ends thereof are disposed above the height of the singulator (76). With a tube (24) so raised, a tube inserter (96) pushes the tube (24) into the tube holder (98) of a manipulator (100). The tube holder (98) is, in turn, pivoted to tilt the tube (24) so that devices (22) within the tube (24) are deposited for introduction into the singulator (76 ).
