Core Exchange Device

The apparatus is utilized for replacing defective cores in planar magnetic two-wire core arrays. A kit comprising an annular substrate with a single prestrung core held by two wires which are releasably held on the substrate by four solder dots as is shown is required to effect the replacement.

Plane 3 containing defective core 7 is mounted in a holder on a core exchange machine. Slide 8 is retracted to expose plane 3 to a fixed microscope
12. Slides 1 and 2 are positioned until the damaged core is under the microscope which is in alignment with die 4. After alignment, slide 8 is moved forward. Locating pins 11 are dropped into place to locate punch 9 and welding tip 10 directly over die 4 and the punch and anvil 5 respectively. Die 4 is raised to the core plane level. Simultaneously with the raising of die 4 the wires are spread by fingers, not shown, to provide the necessary clearance. Punch 9 is actuated and the defective core is removed.

A core kit mounted on carrier strip 6 is positioned above punch 9 and anvil 5 and below welding tip 10. Die 4 is lowered and slide 2 is indexed to center the replacement area over punch 9 and anvil 5. Punch 9 and anvil 5 are raised to carry the kit into the core mat.

Welding tip 10 is lowered and energized to thus solder one wire of the kit to one mat wire. The welding tip is indexed 90 degrees three times to complete the repair. Alternatively, four welding tips can be lowered simultaneously so that the f...
