It should be noted that, referring to fig. 2 to fig. 4, the motor winding coil 100 wound by the winding method of the motor winding coil includes at least two layers of coils, and each layer of coil includes a plurality of turns of wires. Each layer of coil comprises a plurality of first subsections 101 and a plurality of second subsections 102, the plurality of first subsections 101 and the plurality of second subsections 102 are sequentially wound on the outer circumferential surface of the winding die 120 in a staggered and continuous mode, and when the motor winding coil 100 is wound, the winding die 120 rotates for 360 degrees to form the first subsections 101 and the second subsections 102; and based on the above method, when the first subsection 101 is wound, an included angle (as shown by an included angle C in fig. 3) is formed between the first subsection 101 and the axis of the winding die 120, and the included angle ranges from 10 degrees to 70 degrees, and the second subsection 102 is perpendicular to the axis of the winding die 120.
The winding method of the motor winding coil comprises the following steps:
step 1: the winding die 120 rotates around its axis (in the direction of the arrow in fig. 2); the wire outlet nozzle 110 moves from one end of the winding die 120 to the other end of the winding die 120 along the direction parallel to the axis of the winding die 120 until the first layer of coils is wound on the outer peripheral surface of the winding die 120;
step 2: when the (n + 1) th layer of coil is wound, n is an integer larger than or equal to 1, the wire outlet nozzle 110 keeps the position when the tail end coil of the (n + 1) th layer of coil is wound and winds the first circle of conducting wire of the (n + 1) th layer of coil;
and step 3: the limiting device 130 moves towards the direction close to the winding die 120 and abuts against the first circle of conducting wires of the (n + 1) th layer of coil, so as to guide the conducting wires output by the wire outlet nozzle 110 to be sequentially and tightly wound on the winding die 120 along the direction parallel to the axis of the winding die 120; after the limiting device 130 and the winding mold 120 synchronously rotate for the first preset angle, the limiting device 130 moves in the direction far away from the winding mold 120;
and 4, step 4: the wire outlet nozzle 110 moves from one end of the n-th layer of coil to the other end of the winding die 120 along the direction parallel to the axis of the winding die 120 until the rest of the n + 1-th layer of coil is wound;
repeating the steps 2 to 4.
According to the winding method of the motor winding coil, in the process of winding the motor winding coil 100, the winding efficiency of the motor winding coil 100 can be improved through the reciprocating motion of the wire outlet nozzle 110 relative to the winding die 120.
Meanwhile, in the winding process, the turns of the coil are in close contact through the limiting device 130, so that the tightness of the motor winding coil 100 can be improved, the resistance of the motor winding coil 100 can be reduced, the electromagnetic force of the motor winding coil 100 is improved, the phenomenon that an insulating layer is damaged due to friction between the turns of the coil is avoided, and the phenomenon that the coil is burnt due to turn-to-turn short circuit is avoided.
Referring to fig. 1-4, in this embodiment, step 1 is for winding a first layer of coils of the motor winding coil 100, and specifically, in step 1, the step of moving the nozzle 110 from one end of the winding mold 120 to the other end of the winding mold 120 along a direction parallel to the axis of the winding mold 120 (as indicated by arrows in fig. 2-4) until the first layer of coils is wound around the outer circumferential surface of the winding mold 120 includes:
after the wire outlet nozzle 110 moves from one end of the winding mold 120 to the other end of the winding mold 120 along a direction parallel to the axis of the winding mold 120 by a first preset distance (as indicated by mark a in fig. 3), the winding mold 120 rotates by a second preset angle around the axis;
after the wire outlet nozzle 110 is retracted by a second preset distance (as indicated by the mark B in fig. 4) in the direction parallel to the axis of the winding mold 120, the winding mold 120 rotates by a third preset angle around the axis thereof; the sum of the second preset angle and the third preset angle is 360 degrees, and the first preset distance is greater than the second preset distance;
and repeating the steps.
It should be noted that, in the process of winding the first layer coil, since the first preset distance is different from the second preset distance, after the first preset distance and the second preset distance are moved through the wire outlet nozzle 110, different parts of the motor winding coil 100 can be wound along with the rotation of the winding mold 120; moreover, since the first preset distance is greater than the second preset distance, and the moved second preset distance is the retreat after the wire outlet nozzle 110 moves the first preset distance, the wire outlet nozzle 110 moves the first preset distance from the winding mold 120 along the direction parallel to the axis of the winding mold 120, and after the winding mold 120 rotates the second preset angle around the axis, the coil part inclined with respect to the axis of the winding mold 120 on the winding motor coil 100 can be completed; after the nozzle 110 is retracted a second predetermined distance in a direction parallel to the axis of the winding mold 120, the winding mold 120 rotates around the axis thereof by a third predetermined angle, so as to complete winding of the coil portion of the motor winding coil 100 that is perpendicular to the axis of the winding mold 120.
Referring to fig. 1-4, in this embodiment, step 4 is for winding the remaining wire layers of the motor winding coil 100 on the basis of the first layer of the motor winding coil 100, and specifically, in step 4, the step of moving the wire outlet nozzle 110 from one end of the n-th layer of the coil to the other end of the winding die 120 along the direction parallel to the axis of the winding die 120 includes:
after the wire outlet nozzle 110 is in a first preset distance from one end of the wire outlet nozzle to the other end of the wire winding die 120 when the end coil of the nth layer of coil is wound, the wire winding die 120 rotates by a second preset angle around the axis of the wire winding die;
after the wire outlet nozzle 110 retreats for a second preset distance along the direction parallel to the axis of the winding mold 120, the winding mold 120 rotates for a third preset angle around the axis; the sum of the second preset angle and the third preset angle is 360 degrees, and the first preset distance is greater than the second preset distance;
and repeating the steps.
It should be noted that, in the process of winding the remaining wire layers of the motor winding coil 100 on the basis of the first layer of the motor winding coil 100, since the first preset distance is different from the second preset distance, the first part 101 and the second part 102 of the motor winding coil 100 can be wound along with the rotation of the winding mold 120 after the wire outlet nozzle 110 moves the first preset distance and the second preset distance; in addition, because the first preset distance is greater than the second preset distance, and the moved second preset distance is the retreat after the wire outlet nozzle 110 moves the first preset distance, the wire outlet nozzle 110 moves the first preset distance from the winding mold 120 along the direction parallel to the axis of the winding mold 120, and after the winding mold 120 rotates the second preset angle around the axis, the first subsection 101 with an included angle relative to the axis of the winding mold 120 on the winding motor coil 100 can be completed; after the nozzle 110 is retracted a second predetermined distance in a direction parallel to the axis of the winding mold 120, the winding mold 120 rotates around the axis thereof by a third predetermined angle, so as to complete winding of the second section 102 of the motor winding coil 100, which is perpendicular to the axis of the winding mold 120. In addition, when the method is implemented, the included angle C between the first section 101 and the axis of the winding mold 120 can be adjusted by adjusting the first preset distance and the second preset distance.
Secondly, when winding the motor winding coil 100, in order to make the turns of the coil closely contact, in this embodiment, after the winding mold 120 rotates around the axis thereof by a second preset angle, the step of the wire outlet nozzle 110 retreating in the direction parallel to the axis of the winding mold 120 by a second preset distance includes:
the wire outlet nozzle 110 moves relative to the winding die 120 such that the wire between the winding die 120 and the wire outlet nozzle 110 is in a tightened state.
It should be noted that, the purpose of this manner is to make the turns of the coil wound on the winding mold 120 closely contact, and when the wire outlet nozzle 110 moves relative to the winding mold 120, the wire outlet nozzle 110 can move in different directions relative to the winding mold 120, and the purpose is to make the wire between the winding mold 120 and the wire outlet nozzle 110 be in a tensioned state by changing the interval between the winding mold 120 and the wire outlet nozzle 110, so that the wire is less than or equal to the interval between the winding mold 120 and the wire outlet nozzle 110.
In addition, when winding the motor winding coil 100, in order to enable the coil turns to be in close contact after the outlet nozzle 110 moves the first preset distance and the second preset distance, in this embodiment, the first preset distance and the second preset distance are both integer multiples of the diameter of the wire. In addition, the first preset distance is an interval between two ends of the coil part wound on the winding die 120 along the axial direction of the winding die 120 after the winding die 120 rotates by a second preset angle; similarly, the second predetermined distance is an interval between two ends of the coil part wound on the winding die 120 along the axial direction of the winding die 120 after the winding die 120 rotates by the third predetermined angle.
Further, referring to fig. 1-4, in the present embodiment, when the wire outlet nozzle 110 is located at a position where an end coil of the nth layer coil is wound or at a position where a first turn of wire of the (n + 1) th layer coil is wound, the wire between the wire outlet nozzle 110 and the winding mold 120 is perpendicular to the axis of the winding mold 120.
The purpose of this arrangement is to make the end coil of the nth layer coil and the first turn of the wire of the (n + 1) th layer coil perpendicular to the axis of the winding mold 120 at the position where the end coil of the nth layer coil is wound or when the first turn of the wire of the (n + 1) th layer coil is wound.
In addition, when the winding of the first layer coil is started, in the present embodiment, the steps before step 1 include:
the position of the nozzle 110 relative to the winding die 120 is adjusted so that the wire between the nozzle 110 and the winding die 120 is perpendicular to the axis of the winding die 120.
The purpose of this arrangement is to make the first turn of the wire of the layer 1 coil perpendicular to the axis of the winding die 120.
Further, referring to fig. 1-4, in the present embodiment, since the wire outlet nozzle 110 moves from the winding mold 120 to the direction parallel to the axis of the winding mold 120 by the first predetermined distance, and after the winding mold 120 rotates around the axis thereof by the second predetermined angle, the coil portion of the wound motor winding coil 100 inclined with respect to the axis of the winding mold 120 is completed; the motor winding coil 100 wound by the winding method of the motor winding coil has four mutually perpendicular side surfaces, and the coil portion inclined with respect to the axis of the winding mold 120 is located on one of the side surfaces, so that the value range of the first preset angle is as follows: 0 to 100 degrees. In other embodiments of the present invention, the first preset angle may be adjusted according to a difference between the central angles of the side surfaces of the coil portions inclined with respect to the axis of the winding mold 120.
Referring to fig. 1 to 4, in the present embodiment, the above steps 2 to 4 are repeated, that is, the winding operation of one motor winding coil 100 is completed, and at this time, the next motor winding coil 100 may be continuously wound or removed from the winding mold 120 according to actual situations.
Specifically, when it is necessary to start to manufacture the next motor winding coil 100 to form the twins motor winding coil, the method includes:
stopping the rotation of the winding mold 120, moving the wire outlet nozzle 110 relative to the winding mold 120 so that the wire output by the wire outlet nozzle 110 is lapped on the winding mold 120, and repeating the steps 1-4;
the winding mold 120 stops rotating, and the wire outlet nozzle 110 moves relative to the winding mold 120 so that the wire output by the wire outlet nozzle 110 is lapped on the winding mold 120, and the wire between the winding mold 120 and the wire outlet nozzle 110 is cut off.
When it is required to be removed from the winding mold 120, it includes:
the winding mold 120 stops rotating, and the wire outlet nozzle 110 moves relative to the winding mold 120 so that the wire output by the wire outlet nozzle 110 is lapped on the winding mold 120, and the wire between the winding mold 120 and the wire outlet nozzle 110 is cut off.
Based on the above, the embodiment of the invention provides a motor winding coil 100, and the motor winding coil 100 is wound by using the winding method of the motor winding coil.
