The winding process of the motor winding coil is used for manufacturing the coil winding of the motor, the manufactured coil winding is compact in arrangement, small in resistance and high in electromagnetic force, inter-turn friction of the coil is aggravated due to vibration when the coil is electrified, an insulating layer is seriously damaged, and then the situation that the coil is burnt due to inter-turn short circuit is generated is avoided, and the use safety is high.
Obviously, the winding process of the motor winding coil provided by the embodiment can also be used for winding coils required by other equipment.
In this embodiment, the winding process of the motor winding coil includes the following steps:
the plurality of parallel wires 100 are wound on the outer peripheral surface of the mandrel 200, and in the winding process, the plane S defined by the plurality of parallel wires 100 forms an included angle with the outer peripheral surface of the mandrel 200, so that the plurality of parallel wires 100 are sequentially contacted with the outer peripheral surface of the mandrel 200 or the outer peripheral surface of the inner-layer coil which is finished with winding in the extending direction of the mandrel 200.
Referring to fig. 1, in the winding process of the motor winding coil provided in this embodiment, a plurality of parallel wires 100 can be wound on a mandrel 200 at the same time, for example, two parallel wires, three parallel wires, or four parallel wires can be processed at the same time. When the plurality of parallel wires 100 are wound around the mandrel 200, a plane S defined by the plurality of parallel wires 100 forms an included angle with the outer peripheral surface of the mandrel 200, so that in the extending direction of the mandrel 200, a distance D between the plurality of parallel wires 100 and the mandrel 200 is different, in other words, the distance D between the plurality of parallel wires 100 and the outer peripheral surface of the mandrel 200 gradually increases or decreases, so that when the plurality of parallel wires 100 are wound, a line of the plurality of parallel wires 100, which has the shortest distance D with the outer peripheral surface of the mandrel 200, first contacts the outer peripheral surface of the mandrel 200, then a line of the plurality of parallel wires 100, which has the second shortest distance D with the outer peripheral surface of the mandrel 200, contacts the mandrel 200, and so on, the plurality of parallel wires 100 sequentially contact the outer peripheral surface of the mandrel 200. Because the plane S determined by the multiple parallel wires 100 has an included angle with the outer peripheral surface of the mandrel 200, when the multiple parallel wires 100 sequentially contact the outer peripheral surface of the mandrel 200, any two adjacent wires partially coincide in the direction perpendicular to the axis of the mandrel 200, one of the two adjacent wires, which is farther from the outer peripheral surface of the mandrel 200, slides on the surface of the one closer to the outer peripheral surface of the mandrel 200, during the sliding process, the two adjacent wires are always tightly attached, and under the guidance of the one closer to the other, the one farther from the outer peripheral surface of the mandrel 200 is kept away from the one closer to the outer peripheral surface of the mandrel 200, and finally passes over the one closer to contact the outer peripheral surface of the mandrel 200 or the inner coil, and the process is repeated to complete the winding. After the winding of the plurality of parallel wires 100 is completed, the plurality of parallel wires 100 are closely attached and arranged along the extending direction of the mandrel 200, and the coils formed by winding are closely arranged in the extending direction of the mandrel 200, so that the compactness is high.
The mandrel 200 may be a cylindrical shaft, a square cylindrical shaft, or the like, and in the present embodiment, the cross section of the mandrel 200 is rectangular, where the cross section is a plane perpendicular to the extending direction of the mandrel 200. In other words, when the wire is wound around the outer circumferential surface of the mandrel 200, the wire is wound around one circumference to form a rectangular ring, that is, the coil wound around the mandrel 200 is a rectangular coil.
Obviously, the shape of the coil matches the shape of the cross-sectional outer contour of the mandrel 200, and is not limited to a rectangular coil, and is not listed in this embodiment.
In this embodiment, when actually winding, can drive dabber 200 and rotate to make dabber 200 drive the motion of many wires 100 side by side rather than being connected when rotating, make many wires 100 side by side around locating on the outer peripheral face of dabber 200, the winding operation is more convenient, and is convenient for control.
Alternatively, when the plurality of side-by-side wires 100 are wound around the mandrel 200, the plurality of side-by-side wires 100 can reciprocate with respect to the mandrel 200 in the extending direction of the mandrel 200, thereby forming a plurality of layers of coils arranged in a radial direction perpendicular to the extending direction of the mandrel 200 on the outer circumferential surface of the mandrel 200.
Specifically, during the process that the plurality of parallel wires 100 rotate along the circumferential direction of the mandrel 200 relative to the mandrel 200, the plurality of parallel wires 100 move along the first direction relative to the mandrel 200, and a line closer to the rear end of the plurality of parallel wires 100 in the first direction contacts the mandrel 200 or the inner-layer coil before a line closer to the front end, so that a plurality of continuous coils arranged along the extending direction of the mandrel 200 are formed on the mandrel 200, wherein the first direction is parallel to the axis of the mandrel 200. After the plurality of wires 100 are moved in the first direction by a predetermined distance, the plurality of wires 100 are moved in a second direction opposite to the first direction while being wound around the outer circumferential surface of the core shaft 200, so that the outer coil is wound around the inner coil having completed the winding. It should be noted that the number of times that the plurality of side-by-side wires 100 reciprocate in the extending direction of the mandrel 200 with respect to the mandrel 200 is set as needed, and this embodiment is not particularly limited. For example, when the number of reciprocating movements is one, that is, one movement in the first direction and one movement in the second direction are performed, two layers of coils are obtained in the radial direction of the mandrel 200. For another example, when the number of reciprocating movements is two, four layers of coils are obtained in the radial direction of the mandrel 200, and so on. Of course, the winding of the coil may be performed not on the basis of one reciprocating motion but on the basis of a single motion, thereby forming an odd number of layers of the coil.
Further, it is set that, in an initial state, one end of each of the plurality of parallel wires 100 is fixed on the mandrel 200, an angle between a plane S defined by the plurality of parallel wires 100 and the outer peripheral surface of the mandrel 200 is α, and the plurality of parallel wires 100 first move in a first direction to wind to form a first coil during winding; optionally, in an initial state, a blocking structure may be disposed on the mandrel 200 to abut against a coil formed by winding at the beginning, so as to prevent the coil from moving to the second direction under the extrusion action to loosen the coil. Alternatively, the angle α may range from 20 ° to 60 °, obviously also from 30 ° to 45 °, for example, the angle α may be 20 °, 30 °, 40 °, 45 °, or the like. After the step of moving the plurality of parallel wires 100 in the first direction to form the plurality of continuous inner coils arranged in the extending direction of the mandrel 200 on the mandrel 200 and before the step of moving the plurality of parallel wires 100 in the second direction opposite to the first direction while being wound around the outer circumferential surface of the mandrel 200, the plurality of parallel wires 100 are rotated to change the angle of the plane S defined by the plurality of parallel wires 100, so that the wire closer to the rear end among the plurality of parallel wires 100 in the second direction contacts the inner coil before the wire closer to the front end. Optionally, the angle of the plane S defined by the plurality of parallel wires 100 when moving along the second direction is- α, in other words, the plane defined by the plurality of parallel wires 100 when moving along the first direction and the plane defined by the plurality of parallel wires 100 when moving along the second direction are mirror images of each other.
It should be understood that after the plurality of parallel wires 100 move in the second direction for a set distance, the direction needs to be changed to move in the first direction again, and at this time, the plurality of parallel wires rotate to make the angle between the plane S defined by the plurality of parallel wires 100 and the outer circumferential surface of the mandrel 200 be α, and the process is repeated.
It should be noted that, during the process of multiple movements of the multiple parallel wires 100 along the first direction relative to the mandrel 200, the values of the included angles between the plane S defined by the multiple parallel wires 100 and the plane of the outer circumferential surface of the mandrel 200 may be different each time. Similarly, in the process of moving the plurality of parallel wires 100 relative to the mandrel 200 along the second direction for a plurality of times, the value of the included angle between the plane S determined by the plurality of parallel wires 100 and the plane of the outer circumferential surface of the mandrel 200 may be different each time.
In this embodiment, optionally, after the plurality of parallel wires 100 are wound around the mandrel 200 to form a coil with a set number of layers, the wound multilayer coil is cut to be separated from the plurality of parallel wires, so that the wound coil is taken down from the mandrel 200 for subsequent use. For example, a wound coil is used for a winding of a stator of an electric motor.
The embodiment also provides a motor winding coil which is formed by winding the winding process of the motor winding coil mentioned in the embodiment, and the coils are arranged tightly.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
