Abstract

This component handling device is for testing purposes. It comprises a pallet arrangement on which is mounted a plurality of components for transport on a chain conveyor 10 past various test stations. For example, station 1 is in association with heated chamber 2 for environmental testing of components such as transistor 3.

Test Component Handler

This component handling device is for testing purposes. It comprises a pallet arrangement on which is mounted a plurality of components for transport on a chain conveyor 10 past various test stations. For example, station 1 is in association with heated chamber 2 for environmental testing of components such as transistor 3.

A series of transistors 3 are inserted in corresponding holders 4 mounted on pallet 5. Contacts, not shown, are provided for each holder 4 for connection to station I. Pallet 5 includes a series of index holes 6 and a series of coded identification holes 7 for the transistor 3 under test. This code is decoded by a bank of lamps 8 and photosensors 9. The identification of the transistor 3 is recorded on suitable readout devices together with the results of the test. Index holes 6 can be employed alone with a lamp 11-photosensor 12 combination, or with a tape unit, not shown, for control of the movements of chain conveyor 10. The test station 1 can be programmed to perform any number of tests by the tape unit.

This unit uses fiber optics 13, which enable the photosensors to be positioned externally of chamber 2. Fiber optics 13 can be encased in block 14 of a suitable heat insulating material. This is inserted through the wall of chamber 2 in any desired position which permits the fiber optics to transfer light from the lamps to their corresponding photosensors.
