Abstract

The testing of magnetic cores is a delicate and exacting operation. In a tester, such as that illustrated at the left, a clutch controlled drum is provided having eight probes. This arrangement isolates the magnetic fields of the cores from one another. The cores are fed by any suitable feeder 10 to a station 1 where an air blast loads the core on a probe. This reduces the possibility of breakage. The cores may be toroidal or multi-hole as shown at the right, since the probes are interchangeable. Also, by using more than one set of probes on an elongated drum, both types may be tested simultaneously.

Magnetic Core Handler

The testing of magnetic cores is a delicate and exacting operation. In a tester, such as that illustrated at the left, a clutch controlled drum is provided having eight probes. This arrangement isolates the magnetic fields of the cores from one another. The cores are fed by any suitable feeder 10 to a station 1 where an air blast loads the core on a probe. This reduces the possibility of breakage. The cores may be toroidal or multi-hole as shown at the right, since the probes are interchangeable. Also, by using more than one set of probes on an elongated drum, both types may be tested simultaneously.

The drum is indexed under control of the clutch to the test station 2 where the probe passes between two sets of spring contacts, one bearing on the probe and the other on the drum to complete the test circuit. Simultaneously a new core is positioned on the probe at station 1. When the test is completed, the drum is indexed carrying the core to the accept station 3. Here, if the core meets certain standards, a signal from the test circuit will actuate a valve at 11 to admit a blast of air and so eject the core from the probe into a receiving bin. Should the core be unacceptable, the drum is again indexed to bring the core to the reject station 4 where a periodic opening of a valve at 11 will admit a blast of air to eject the core into a reject bin.
