DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of fusing an amateur for a flat motor for fusing a connecting wire of a coil element to a hook of an amateur commutator used for a flat motor, and to use the method. The present invention relates to a connecting line bending device.

[0002]

2. Description of the Related Art In general, an armature used for a flat motor is constituted by arranging a large number of unit coil elements, which are conventionally manufactured separately, in a state of being partially overlapped at a predetermined angle outside the commutator. Hook the coil wire of the element to the hook of the commutator, then contact the electrodes, energize and fuse and connect,
These are formed by fixing with resin.

However, in such a conventional method of manufacturing an armature for a flat motor, since a large number of unit coil elements manufactured separately are used as the coil elements, the number of parts is increased, and the process from winding to assembling is increased. However, there is a problem that the process of the above is complicated and the manufacturing cost is increased.

Therefore, for example, Japanese Patent Application Laid-Open No. 56-15995
As disclosed in Japanese Unexamined Patent Application Publication No. 2 (2003), that is, as shown in FIG. As shown in FIG. 11, it is arranged around the commutator 15, and the central part of the connection line 13 is fused to the hook 17 of the commutator 15.

However, in such a conventional method of manufacturing an amateur for a flat motor, since a large number of coil elements 11 are formed continuously, fusing of the coil elements 11 to the hooks 17 of the commutator 15 is automated. It is very difficult to do so, and there is a problem that a large number of manufacturing steps are required due to the manual work.

Accordingly, for example, Japanese Patent Application Laid-Open No. 3-203555
A fusing method of an amateur for a flat motor as disclosed in Japanese Unexamined Patent Publication (Kokai) No. H11-157421 has been developed. According to this method, as shown in FIG. 12, the coil element 11 is arranged on the transport jig 19 in a state of being erected radially so that the connection line 13 of the coil element 11 is located on the center side, and then arranged radially. The connecting line 13 is connected to the guide plate 2
1, the commutator 15 is inserted into the center upward from below, so that the hook 17 opens upward, and the connection line between the hook 17 of the commutator 15 and the coil element 11 is inserted. 13, and in this state, as shown in FIG. 13, the fusing electrode 23 fuses the hook 17 and the connection line 13.

According to this method, the connecting wires 13 of a plurality of coil elements 11 continuously formed by one coil wire e can be quickly and reliably fused to the hooks 17 of the commutator 15. .

[0008]

However, in this fusing method, as shown in FIG. 14, the connection wire 13 of the coil element 11 may extend to the upper end surface 25 of the commutator 15 in some cases. In such a case, as shown in FIG. 15, the connection line 13 is often caught on the slit 27 formed on the outer periphery of the commutator 15 on the upper end surface 25 of the commutator 15, and in this case, However, there has been a problem that the connecting wire 13 cannot be fused to the hook 17 of the commutator 15.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and a method of fusing an amateur for a flat motor and a method thereof capable of reliably preventing a connection line from being caught on an upper end surface of a commutator.
