ABSTRACT:
A tester/sorter for performing electrical tests on axial lead devices such as diodes at a very high throughput rate carries the devices on the periphery of a rotating wheel. A contactor assembly periodically makes electrical connection with one or more of the axial lead devices. A flying arm assembly mounts the contactor assembly so that it travels through a closed loop path of motion with respect to the wheel. In a first path portion, mechanical controls acting on the flying arm assembly lower the contactor assembly into electrical contact with the leads of the device. Once in electrical connection, there is no relative motion between the contactor assembly and the leads. After the test is completed, the mechanical controls lift the contactor assembly away from the leads and return it to its starting position. This travel is substantially free of mechanical impacts that could produce vibrations and thereby degrade the accuracy of the testing.
