Description

Description: 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 connection wire of a coil element to a hook of an amateur commutator used for a flat motor. .

[Conventional technology]

In general, amateurs used for flat motors are
Conventionally, a large number of unit coil elements manufactured separately are arranged outside the commutator at a predetermined angle and partially overlapped, and the coil wire of the unit coil element is fused to a hook of the commutator, and the like. It is formed by fixing with resin.

As a method of manufacturing such an armature for a flat motor, a method disclosed in, for example, Japanese Patent Application Laid-Open No. 60-5759 is known.

However, in such a conventional method of manufacturing an amateur for a flat motor, since a large number of unit coil elements manufactured separately are used as coil elements, the number of parts increases, and the process from winding to assembly is reduced. There has been a problem that the structure becomes complicated and the manufacturing cost increases.

Therefore, as disclosed in, for example, Japanese Patent Application Laid-Open No. 56-159952, that is, as shown in FIG. 8, a large number of coil elements 11 are connected by a single coil wire e via a connection wire 13. This coil element 11 is
As shown in the drawing, the commutator 15 is arranged around the commutator 15 and the central portion of the connection line 13 is fused to the hook 17 of the commutator 15.

And such a continuous coil element 11
For example, as shown in FIG. 10, a plurality of flat winding jigs 21 through which a shaft 19 is inserted at the center are sequentially wound with a coil wire e from one side, and the coil element 11 is wound around each winding jig 21. Are formed by continuously adhering coil wires e forming the coil element 11 to each other by energizing the continuous coil element 11 after the
Thereafter, the coil element 11 is sequentially removed from the winding jig 21, the detached coil element 11 is fused to the hook 17 of the commutator 15, and resin molding is performed in this state.

[Problems to be solved by the invention]

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, it is very difficult to automate fusing of the coil elements 11 to a commutator. However, there is a problem that a large number of man-hours are required due to manual work.

The present invention has been made to solve such a conventional problem, and quickly and reliably locks a connection wire of a plurality of coil elements formed continuously by one coil wire to a hook of a commutator. It is an object of the present invention to provide a method of fusing an amateur for a flat motor, which can be fused.
