Abstract

A wire tension control device including a bobbin and a magnetic moment generator is provided. The bobbin is configured to provide a wire. The magnetic moment generator includes a stator and a rotor relatively rotatable with respect to the stator. The rotor is connected to the bobbin. When the bobbin drives the rotor to rotate, the magnetic moment generator generates a tension on the wire.

First claim

What is claimed is:

1 . A wire tension control device, comprising:
a bobbin configured to provide a wire; and a magnetic moment generator, comprising a stator and a rotor relatively rotatable with respect to the stator, wherein the rotor is connected to the bobbin, and the magnetic moment generator generates a tension on the wire when the bobbin drives the rotor to rotate.

2 . The wire tension control device according to claim 1 , wherein the stator or the rotor comprises:
a core; and a coil winded on the core; wherein the wire tension control device further comprises a load electrically coupled to the coil.

3 . The wire tension control device according to claim 2 , wherein the load is a resistor.

4 . The wire tension control device according to claim 2 , wherein the load is an electronic device.

5 . The wire tension control device according to claim 4 , wherein the electronic device is a wireless communication module or a display.

6 . The wire tension control device according to claim 1 , wherein the position of the stator is adjustable.

7 . The wire tension control device according to claim 6 , wherein the magnetic moment generator further comprises a transmission shaft, and the wire tension control device further comprises:
a course adjustment element connected to the stator and configured to adjust the position of the stator along the extension direction of the transmission shaft.

8 . The wire tension control device according to claim 7 , further comprising:
a base having an outer screw; wherein the course adjustment element has an inner screw, and the inner screw and the outer screw are relatively ratable to be engaged with each other.

9 . The wire tension control device according to claim 8 , further comprising:
an anti-loose element located between the base and the course adjustment element.

10 . The wire tension control device according to claim 1 , further comprising:
a speed control mechanism connected to the rotor and configured to change the rotation speed of the rotor.

11 . The wire tension control device according to claim 1 , wherein the wire is not in contact with the magnetic moment generator.

12 . A braiding machine, comprising:
a driver; and a wire tension control device disposed on the driver and comprising:
a bobbin configured to provide a wire; and
a magnetic moment generator, comprising a stator and a rotor relatively rotatable with respect to the stator, wherein the rotor is connected to the bobbin, and the magnetic moment generator generates a tension on the wire when the bobbin drives the rotor to rotate;
wherein the driver is configured to braid the wire provided by the wire tension control device on a mandrel.

13 . The braiding machine according to claim 12 , wherein the stator or the rotor comprises:
a core; and a coil winded on the core; wherein the wire tension control device further comprises a load electrically coupled to the coil.

14 . The braiding machine according to claim 13 , wherein the load is a resistor.

15 . The braiding machine according to claim 13 , wherein the load is an electronic device.

16 . The braiding machine according to claim 15 , wherein the electronic device is a wireless communication module or a display.

17 . The braiding machine according to claim 12 , wherein the position of the stator is adjustable.

18 . The braiding machine according to claim 17 , wherein the magnetic moment generator further comprises a transmission shaft, and the wire tension control device further comprises:
a course adjustment element connected to the stator and configured to adjust the position of the stator along the extension direction of the transmission shaft.

19 . The braiding machine according to claim 18 , further comprising:
a base having an outer screw; wherein the course adjustment element has an inner screw, and the inner screw and the outer screw are relatively ratable to be engaged with each other.

20 . The braiding machine according to claim 19 , further comprising:
an anti-loose element located between the base and the course adjustment element.
