Abstract

In this method and apparatus for assembling the cores and windings for a magnetic core array, plate 10 has funnel-shaped slots 12 etched into its edge portions to guide the drive wires. These slots lead to openings etched through plate 10 to properly position the magnetic cores. Plate 14 has openings etched to guide the cores from container 16 to the proper position for assembly into the array. Plate 18 is positioned between plates 10 and 14. Plate 18 is provided with slots to guide the sense wires through the cores at an angle relative to the drive wires. A magnetic core array is assembled by placing the plates back-to-back so that the cores in container 16 drop into position in the slots formed by plates 10 and 14. A vacuum source is then coupled to vacuum chuck 20 to hold the cores in position.

Stringing Ferrite Cores

In this method and apparatus for assembling the cores and windings for a magnetic core array, plate 10 has funnel-shaped slots 12 etched into its edge portions to guide the drive wires. These slots lead to openings etched through plate 10 to properly position the magnetic cores. Plate 14 has openings etched to guide the cores from container 16 to the proper position for assembly into the array.

Plate 18 is positioned between plates 10 and 14. Plate 18 is provided with slots to guide the sense wires through the cores at an angle relative to the drive wires. A magnetic core array is assembled by placing the plates back-to-back so that the cores in container 16 drop into position in the slots formed by plates 10 and
14. A vacuum source is then coupled to vacuum chuck 20 to hold the cores in position. All X drive wires 22 and then Y drive wires 24 are passed through the cores to provide the drive windings. The sense wires are then guided by plate 18 through the cores. Sense wires 26 are then looped at the ends to form the desired sense winding.
