In the motor winding device tangled to the commutator, a roller vertical movement mechanism having a vertical movement roller that contacts the magnet wire is provided between the tension adjusting unit and the motor winding machine, and the motor core At the time of winding, the vertically moving roller is lowered from a first predetermined position to bend the flange, and a predetermined first tension is applied to the magnet wire. Is returned to the first predetermined position to make the collar portion straight and to be in a talmi state without the first tension. Further, the vertical movement roller of the roller vertical movement mechanism is configured to move up and down by a linear actuator, and the motor winding method according to the present invention uses the first roller as a tip. In the motor winding method, a magnet wire sent through a tension adjusting unit having a bendable collar portion is wound around a motor core of a motor rotor by a motor winding machine and entangled with a commutator. A roller vertical movement mechanism having a vertical movement roller that contacts the magnet wire is provided between the adjustment unit and the motor winding machine, and when winding the motor core, the vertical movement roller is lowered from the first predetermined position. The bend is bent, a predetermined first tension is applied to the magnet wire, and the In some cases, the vertical movement roller is returned to the first predetermined position so that the collar portion is straight and the first tension is removed, and the vertical movement of the roller vertical movement mechanism is performed. The roller is a method of moving up and down by a linear actuator.

Since the motor winding method and apparatus according to the present invention are configured as described above, the following effects can be obtained.

It is a block diagram which shows the time of entanglement with respect to the commutator of FIG. It is a block diagram which shows the tension adjustment mechanism in the conventional motor winding apparatus.

  According to the motor winding method and apparatus of the present invention, a tension is applied when the motor core is wound by the tension adjusting mechanism, and a tension-free tarmi state is obtained when the commutator is curled, thereby causing disconnection when the commutator is curled. It is that you can make a baldness without it.

Hereinafter, preferred embodiments of a motor winding method and apparatus according to the present invention will be described with reference to the drawings.
In addition, the same code | symbol is demonstrated to the part which is the same as that of a prior art example, or an equivalent part.
In FIG. 1, what is indicated by reference numeral 1 is a conventionally used motor winding machine. In this motor winding machine 1, a commutator 22 and a motor core 23 provided on a rotating shaft 21 of a motor rotor 20 are used. On the other hand, the magnet wire 2 can be wound or wound by the needle 24 configured to be linked two-dimensionally or three-dimensionally.

The magnet wire 2 fed into the needle 24 is configured to be continuously drawn out from a bobbin 3 around which the magnet wire 2 is wound, and the magnet wire 2 from the bobbin 3 is connected to a tension adjusting unit 25. It is configured to be sent to the needle 24 through the tension adjusting roller 25A, the first roller 12, the up-and-down moving roller 14, and the second roller 13 of the flange 26 of the tension adjusting unit 25.
As is well known, the tension adjusting roller 25A is configured to adjust the degree of sliding when the magnet wire 2 is supplied.

It is configured to be able to be bent in an arc shape or to return to a straight shape as shown in FIG. That is, it has the effect of removing the talmi of the magnet wire 2.

  The vertical movement roller 14 is provided at a lower end 28 a of a rod 28 that can move up and down of a known linear actuator 27, and the linear actuator 27 and the vertical movement roller 14 constitute a roller vertical movement mechanism 29.

  Next, in the configuration described above, when the magnet wire 2 is wound around the motor core 23 of the motor rotor 20 using the needle 24 of the motor winding machine 1, as shown in FIG. As shown in FIG. 1, the rod 28 of the roller vertical movement mechanism 29 is moved along the direction of the arrow A to a first predetermined position C (as shown in FIG. 1, the vertical movement roller 14 is raised to the upper limit. Position) When the lower end reaches the second predetermined position F, the tip 26a of the flange portion 26 is pulled downward together with the first roller 12, so that the entire first flange portion 26 is bent like a bow. Tension D is applied.

  In the above-described state, the needle 24 of the motor winding machine 1 is operated two-dimensionally and three-dimensionally with respect to the motor core 23, whereby the first tension D, which is a high tension, is applied to the winding of the magnet wire 2 to the motor core 23. Winding is possible under the condition of
