The NR inductor includes at least an inductor base and a coil wound on the inductor base. The two ends of the inductance base body are disks, a winding groove is formed between the two disks, and a winding device winds copper wires in the winding groove to form the coil. In addition, a transverse groove having a diameter that passes through one of the disks is formed in the surface of the other disk, and after the winding is completed, the ends of the copper wire at both ends need to be placed in the transverse groove, and a solder surface is formed on the surface of the disk on which the transverse groove is formed. Meanwhile, gaps are formed at two ends of the transverse groove and are horn-shaped, so that the copper wire can enter the transverse groove on one hand, and the copper wire can be prevented from protruding from the side face of the inductance substrate on the other hand. Meanwhile, positioning planes are formed on opposite side surfaces of each disc, the positioning planes are parallel to planes determined by the transverse grooves and the axis of the inductance substrate, and the distance between the two positioning planes on the same disc is smaller than the diameter of the disc.

In order to avoid the influence of the wire clamp 505 on the rotation of the wire guide 407, the wire clamp 505 needs to be retracted by a distance in the Y direction after clamping the wire end. After the wire guiding needle 407 is wound, the clamp 410 and the wire guiding needle 407 are raised by a distance and then moved to the right side of the corresponding collet 304, thereby completing the clamping process of the copper wire positioned between the collet 304 and the wire guiding needle 407 by the clamp 410 and the cutting process of the copper wire positioned between the collet 304 and the wire guiding needle 407.

When the wire clamp 505 is located on the left side of the chuck 304, the copper wire at the wire head penetrates in from the right side and penetrates out from the left side of the wire clamp 505, when the wire clamp 505 moves to the right side of the chuck 304, the copper wire at the wire head changes to extend to the right side of the wire clamp 505 first and then penetrates out from the left side of the wire clamp 505, and 180-degree bending occurs, so that the processing of subsequent procedures is not facilitated, and therefore, in the process that the wire clamp 505 moves to the right side from the left side of the chuck 304, the wire clamp 505 simultaneously rotates clockwise by 180 degrees, and the wire head can be guaranteed to be basically kept in a straight state. Of course, in order to avoid collision of the wire clamp 505 with the collet 304, the wire clamp 505 may move upward a distance when moving from the left side to the right side and then descend a distance when reaching the right side.

When the wire clamp 505 needs to clamp a wire, the wire clamp is in an initial state, after the wire clamping is completed, the wire clamp 505 retreats, due to the fact that a copper wire has a certain tension force before entering the wire guide needle, the wire clamp 505 rotates clockwise by a certain angle in a state of being viewed from the top in the retreating process, in addition, in the wire winding process, in order to reduce the length of a wire clamping head clamped by the wire clamp 505, when the wire guide needle 407 winds a workpiece to rotate, the clamp head 304 also drives the workpiece to rotate, the steering direction of the clamp head 304 is the same as that of the wire guide needle 407, the rotating speed of the clamp head 304 is not larger than the rotating speed of the wire guide needle 407, and the rotating number of turns of the clamp head 304 is.
