Abstract

An automatic testing machine which picks up electrical components such as transistors from a feed mechanism and feeds them to spaced clamped positions at the periphery of a test wheel. The test wheel is turned by a stepper motor and the electrical devices are tested at one or more positions by clamping their terminals between two jaws, which contain contact fingers connected to test circuits. After testing, the results are registered in an electronic memory circuit and made available for a sorting action. A series of chutes and bins is positioned around the test wheel and the tested devices are discharged into the bins according to the results of the tests. A fast stepping motor and a low inertia test wheel permit test proceedures of high speed.
