Description: [Object of the Invention] (Field of Industrial Application) The present invention relates to a coil winding method for forming a coil by winding a conductive wire in multiple layers on a winding frame.

(Prior Art) A conventional coil winding device has a structure in which an oblong winding frame 1 is rotated by a drive shaft 2 as shown in FIG. When the coil 3 is formed by winding, the leading end of the conductive wire 4 is locked in the locking groove 5 of the winding frame 1, and then the winding frame 1 is rotated while applying the tension T to the conductive wire 4 to rotate the conductive wire 4. Is to be wound in multiple layers.

However, since the conductor wire 4 has a certain degree of rigidity,
When a tension T is applied to the conducting wire 4 at the time of winding, the conducting wire 4 is not wound so as to be in close contact with the entire circumference of the winding frame 1, and as shown in FIG. It is wound while a gap S is partially formed between it and the circumference. The gap S tends to increase as the rigidity of the conductive wire 4 increases, the tension T decreases, and the curvature radius R 0 of the corner portion of the winding frame 1 decreases. When the conductor wire 4 is further wound with the gap S formed in this manner, so-called winding tightening occurs due to the tension T of the conductor wire 4 wound afterwards as shown in FIG. The conductor wire is deformed in a wave shape, and many small gaps S 1 are generated between the winding layers. Such a large number of small gaps S 1 cause generation of voids during the resin impregnation treatment in the subsequent process, which leads to a decrease in insulation life due to void discharge. Further, as shown in FIG. 8, when the coil 3 after winding is sandwiched between the central molding die 6 and the outer molding dies 7, 7 and pressure-molded, the tops of the corrugated portions on the inner circumference of the coil 3 Since the pressing force of the outer molding die 7 is received as a concentrated load between the central molding die 6 and the central molding die 6, the insulating coating in that portion is damaged.

Next, the operation of the above configuration will be described. When carrying out the winding work, the diameter of the winding frame 18 is reduced in consideration of the amount of floating (amount of loosening) of the conducting wire 21 from the outer periphery of the winding frame 18 at the beginning of winding. To reduce the diameter, use the motor of the frame moving mechanism 35.
By rotating the male screw member 33 in a predetermined direction by 32, the slide block 30 and thus the mandrel 26 are moved to the right in FIG. As a result, both L-shaped levers 23 are rotated about the shaft 24 in the directions of the arrows in FIG.
Are slid in the direction of narrowing the gap. At this time, by detecting the rotational position of the motor 32 by the position detector 36, the sliding amount and thus the position of both frame bodies 19 are detected,
The motor 12 is stopped when the length of the winding frame 18 is reduced to a predetermined dimension W 0 (see FIG. 2). After that, the tip of the conductive wire 21 is locked in the locking groove 22 of the winding frame 18, and the winding frame 18 is rotated by the motor 12 via the drive shaft 13 while applying the tension T to the conductive wire 21. 21 is rolled up. Even in this case, the several turns at the beginning of winding are in a state of floating from the straight line portion of the outer periphery of each frame 19 due to the rigidity of the conductor 21, and the gap S is formed between the outer periphery of each frame 19 as shown in FIG. Is formed. Therefore, in the present embodiment, the number of rotations of the winding frame 18 from the beginning of winding is counted by the rotation detector 37 and the counter 39, and when the number of turns of the conductive wire 21 reaches a predetermined number during the winding, the motor
12 is once stopped and the diameter of the bobbin 18 is enlarged. To increase the diameter, the motor 32 of the frame moving mechanism 35 is rotated in the opposite direction to the above to move the mandrel 26 leftward in FIG. By rotating in the direction opposite to the direction of the arrow in the figure, both frame bodies 19 are slid in the direction of expanding the space between them. At this time, similarly to the above, the rotational position of the motor 32 by the position detector 36, and by extension, both frame members 19
The position of the coil 18
The motor 12 is stopped when it is expanded to the same size W 1 (see FIG. 3) as the inner diameter of the motor. When the diameter of the winding frame 18 is increased in this manner, the coils 40 wound up to that point are
It is pushed and spread in the left-right direction in FIG. 2 by 19 and accordingly, the coil 40 is deformed so that the vertical dimension in FIG. 2 is narrowed. As a result, as shown in FIG. 3, the gap S between the inner circumference of the coil 40 and the linear portion of the outer circumference of each frame 19 is eliminated, and the inner circumference of the coil 40 is evenly adhered to the entire outer circumference of each frame 19. It will be. After this, reel again
Rotate 18 and wind the wire 21 until the desired number of turns is reached. At this time, since the already-wound conducting wire 21 is in close contact with the outer periphery of the winding frame 18 without any gap, the conducting wire 21 that is subsequently wound does not cause winding tightening. Occurrence of a gap due to this is prevented. Moreover, the bending radius of the conductive wire 21 at each corner portion of the winding frame 18 is expanded from R 0 at the beginning of winding by the thickness dimension of the winding layer of the conductive wire 21 to R 1, and the bending radius of the conductive wire 21 is increased. Since the degree of the wire is gradually loosened, the conductive wire 21 wound thereafter comes to evenly adhere to the outer circumference of the already wound conductive wire 21, and no gap is generated between the winding layers. Since the bending radius R 1 at which no gap is generated between the winding layers varies depending on the size and rigidity of the conductive wire 21, the tensile force applied to the conductive wire 21, and the like, it is obtained in advance by experiments and the like. After winding to R 1 , the process proceeds to the enlarging process of the bobbin 18 described above.

Between the winding layers of the coil 40 formed as described above,
Since no gap is formed as shown in FIGS. 4 and 5, voids are less likely to occur between the winding layers during the resin impregnation treatment in the subsequent step, and deterioration of insulation due to void discharge can be suppressed. In addition, since the inner circumference of the coil 40 is not bent into a waveform as in the conventional case, the load applied to the inner circumference of the coil 40 during the pressure molding process of the coil 40 is not partially concentrated and is entirely concentrated. Evenly distributed, the insulation coating 21a (see FIG. 5) is prevented from being damaged by the load, and the insulation is surely improved in combination with the above-mentioned circumstances.

Although the motor 32 is used as the drive source of the frame moving mechanism 35 in the above embodiment, a hydraulic cylinder, a pneumatic cylinder or the like may be used instead. Further, in the above-described embodiment, the winding frame 18 is of a two-part type (two frame members 19), but for example, a three-part type (a rectangular frame member is provided with semicircular frame members on both sides thereof, respectively). Stuff). Furthermore, the shape of the winding frame 18 is not limited to the oval shape, and may be, for example, an isosceles trapezoidal shape (so-called namako shape).

Further, in the above embodiment, the position of the frame body 19 is indirectly detected by detecting the rotational position of the motor 32 of the frame body moving mechanism 35 by the position detector 36, but instead of this, for example, the frame A detector for directly detecting the position of the body 19 may be provided as the position detector.

The conductive wire is wound with, then the diameter of the winding frame is enlarged so as to be the same as the finally required inner diameter of the coil, and the conductive wire is wound to the end in this state. Coil winding method.
