Abstract
Abstract An apparatus for the high-speed handling of integrated circuit parts. The apparatus consists essentially of two parts, a test wheel and a sort wheel. It singulates parts from a reservoir of untested parts, moves the parts to electrical contacts for test, moves the tested part out of the contacts and sorts the part into the proper bin.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
90 words
An apparatus for handling a series of individual parts for testing at a test fixture and sorting which comprises: a first vertical wheel provided with slots disposed arounds its periphery for singulating said parts, presenting them for tests at said test fixture, and moving them away from said test fixture; and a second horizontal wheel for sorting said parts into a plurality of selected categories, said second wheel being positioned below said first wheel and having holes provided about its periphery for accepting said parts dropped from said first wheel.
Claim 2
Independent Claim
90 words
An apparatus for handling a series of individual parts for testing at a test fixture and sorting which comprises: a first vertical wheel provided with slots disposed arounds its periphery for singulating said parts, presenting them for tests at said test fixture, and moving them away from said test fixture; and a second horizontal wheel for sorting said parts into a plurality of selected categories, said second wheel being positioned below said first wheel and having holes provided about its periphery for accepting said parts dropped from said first wheel.
Claim 3
Dependent Claim
56 words
The apparatus of claim 1 wherein said first wheel is a low-mass wheel which rotates about a horizontal axis in discrete partial revolutions to allow said series of individual parts in continuous sequence to drop into said slots, to be rotated into position for test, and to be further rotated to drop into said second wheel.
Claim 4
Dependent Claim
43 words
The apparatus of claim 1 wherein said second wheel is a low-mass wheel which rotates about a vertical axis to position one of said holes above a predetermined sort track allowing said part contained in said hole to drop into said sort track.
Claim 5
Dependent Claim
54 words
The apparatus of claim 1 wherein said first element and said second element work in concert so that in the time interval when said second element is sorting one of said individual parts said first element is singulating, presenting for test, testing, and moving away from the test fixture others of said individual parts.
Claim 6
Dependent Claim
17 words
The apparatus of claim 1 wherein said individual parts are integrated circuit parts packaged in dual-in-line packages.
Claim 7
Independent Claim
117 words
An apparatus for handling a series of individual parts for testing at a test fixture and sorting which comprises: a first vertical wheel provided with slots disposed about its periphery for singulating said parts, presenting them for testing at said test fixture, and moving them away from said test fixture; and a second horizontal wheel for sorting said parts, said second wheel positioned below said first wheel and having holes provided about its periphery for accepting said parts from said first wheel, said second wheel being rotatable about a vertical axis to position one of said holes above a predetermined sort location, said part being held in said hole during said rotation by the forces of acceleration.
Claim 8
Independent Claim
117 words
An apparatus for handling a series of individual parts for testing at a test fixture and sorting which comprises: a first vertical wheel provided with slots disposed about its periphery for singulating said parts, presenting them for testing at said test fixture, and moving them away from said test fixture; and a second horizontal wheel for sorting said parts, said second wheel positioned below said first wheel and having holes provided about its periphery for accepting said parts from said first wheel, said second wheel being rotatable about a vertical axis to position one of said holes above a predetermined sort location, said part being held in said hole during said rotation by the forces of acceleration.
