Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a fusing method for a flat motor armature for fusing a coil element connection wire to a hook of an armature commutator used for a flat motor.

[Conventional technology]

In general, armatures used in flat motors traditionally consist of a large number of separately manufactured unit coil elements.
They are arranged outside the commutator at a predetermined angle and partially overlapped, the coil wires of the unit coil elements are fused to the hooks of the commutator, and these are fixed with resin.

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

However, in this conventional manufacturing method for armatures for flat motors, a large number of separately manufactured unit coil elements are used as coil elements, which increases the number of parts and slows down the process from winding to assembly. There was a problem that the process became complicated and the manufacturing cost increased.

Therefore, for example, as disclosed in Japanese Patent Application Laid-Open No. 56-159952, as shown in FIG. The coil element 11 is arranged around the commutator 15 as shown in FIG.
Fusing is carried out to the hook 17 of.

And, such a continuous coil element 11 is
For example, as shown in FIG. 10, the coil wire e is sequentially stacked and wound around a plurality of flat winding jigs 21 through which the shaft 19 is inserted, starting from the negative side, and the coil element 11 is wound around each winding jigs 21. After forming the coil elements 11 continuously, by applying current to the continuous coil elements 11, the coil elements 11
After that, the coil elements 11 are sequentially removed from the winding jig 21, and the removed coil elements 11 are fused to the hook 17 of the commutator 15. In this state, it is manufactured by resin molding.

[Problem to be solved by the invention]

However, in such a conventional method of manufacturing an armature for a flat motor, since a large number of coil elements 11 are formed in succession, it is very difficult to automate the fusing of the coil elements 11 to the commutator. There was a problem in that the method had to rely on manual labor and required a large amount of manufacturing man-hours.

The present invention has been made in order to solve such conventional problems, and it is possible to quickly and reliably connect the connecting wires of a plurality of coil elements successively formed by a single coil wire to the hook of a computer ξ. It is an object of the present invention to provide a method for fusing an armature for a flat motor, which allows fusing after locking.

[Means to solve the problem]

A method for fusing a flat motor armature according to the present invention is a method for fusing a plurality of coil elements continuously formed by one coil wire to a hook of a computer ξ. In the fusing method, the coil elements are arranged in a radial manner with the connection wires of the coil elements facing the center, and the commutator is placed in the center from below to the top, and the hook is opened upward. The coil element is inserted in such a manner that the connecting wire of the coil element is engaged with the hook of the commutator, and in this state, the hook and the connecting wire are fusing.
