Abstract

A wire disposing assembly having a support, an axial traverser sub-assembly, a support arm, and a linear stage is provided. The support is configured to receive a plurality of turns of a wire, where the support is configured to rotate. The axial traverser sub-assembly is operatively coupled to the support. Further, a rate of motion of the axial traverser sub-assembly is coupled to a speed of rotation of the support. The support arm includes a resin unit configured to dispose resin on at least a portion of the wire, and a wire disposing device configured to guide a portion of the wire being disposed on a surface of the support. The linear stage is operatively coupled to the support arm.

First claim

The invention claimed is:

1. A wire disposing assembly configured to produce precision magnetic coil windings, comprising:
a support configured to receive a plurality of turns of a wire of the precision magnetic coil windings, wherein the support is configured to rotate;
an axial traverser sub-assembly operatively coupled to the support, wherein a rate of motion of the axial traverser sub-assembly is based on a speed of rotation of the support;
a support arm comprising a wire disposing device configured to guide a portion of the wire being disposed on a surface of the support; and
a linear stage operatively coupled to the support arm, wherein the axial traverser sub-assembly and the linear stage are mechanically decoupled from one another.

2. The wire disposing assembly of claim 1 , wherein the support arm further comprises a wire position sensor.

3. The wire disposing assembly of claim 2 , wherein the wire position sensor comprises a profilometer configured to provide data representative of a profile of the wire disposed on a surface of the support.

4. The wire disposing assembly of claim 1 , wherein the wire disposing device comprises a guiding wheel, a slot, a channel, or combinations thereof.

5. The wire disposing assembly of claim 4 , wherein the guiding wheel is operatively coupled to an adjustable wheel shaft.

6. The wire disposing assembly of claim 1 , wherein the support arm further comprises a camera.

7. The wire disposing assembly of claim 1 , further comprising a drive unit configured to control a speed of rotation of a shaft of the support.

8. The wire disposing assembly of claim 7 , further comprising a mechanical pedal operatively coupled to the shaft to control a speed of rotation of the shaft.

9. The wire disposing assembly of claim 7 , wherein the drive unit is configured to automate the speed of rotation of the support.

10. The wire disposing assembly of claim 1 , further comprising an idler wheel configured to determine a feed rate of the wire from a supply source to the support.

11. The wire disposing assembly of claim 1 , wherein the linear stage is configured to dispose the wire in a form of a plurality of loops, where each loop comprises a circular portion and a transition region, and wherein a plane of the circular portion of the loop is parallel to a cross-sectional plane of the support.

12. The wire disposing assembly of claim 1 , further comprising a resin unit configured to dispose a resin on at least a portion of the wire.

13. The wire disposing assembly of claim 12 , wherein the resin unit comprises a cartridge container, a dispensing device, a resin cartridge, and a centering device.

14. The wire disposing assembly of claim 12 , wherein the resin unit comprises a resin with solid fillers.

15. The wire disposing assembly of claim 12 , wherein the resin unit comprises a resin without fillers.

16. The wire disposing assembly of claim 13 , wherein the centering device is configured to control a position of the dispensing device in the resin unit.

17. The wire disposing assembly of claim 13 , wherein the resin unit comprises:
a cartridge container having a first opening and a second opening, wherein the first opening is configured to receive the wire, and wherein the second opening is configured to provide an exit passage to the wire; and
a dispensing device disposed on the second opening of the cartridge container.

18. The wire disposing assembly of claim 17 , wherein the dispensing device comprises a needle, a split wire coating die, or both.

19. The wire disposing assembly of claim 17 , wherein the dispensing device is configured to calibrate a desirable amount of epoxy to be dispensed on the wire.

20. A wire disposing assembly configured to produce precision magnetic coil windings, comprising:
a support configured to receive a plurality of turns of a wire of the precision magnetic coil windings, wherein the support is configured to rotate;
a frame configured to house the support;
a radial positioning device operatively coupled to the frame and the support;
an axial traverser sub-assembly operatively coupled to the support, wherein a rate of motion of the axial traverser sub-assembly is coupled to a speed of rotation of the support;
a support arm comprising a wire disposing device configured to guide a portion of the wire being disposed on a surface of the support; and
a linear stage operatively coupled to the support arm, wherein the support arm further comprises a wire position sensor.
