Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for arranging coils of a flat motor armature for arranging coil elements around a commutator of the armature used for a flat motor.

[Prior Art] In general, armatures used in flat motors conventionally 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.

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. Then, the coil elements 11 are arranged outside the commutator 15 in a state where they are partially overlapped,
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, it is extremely difficult to fit an example of all the coil elements 11 under the adjacent coil elements 11, as shown in FIG. ,
An example of the coil element 11 at the end of the assembly is placed on the coil element 11 at the beginning of the assembly, resulting in a problem that the balance is very poor.

Furthermore, since the coil elements 11 are formed continuously, it is very difficult to automate the arrangement of the coil elements 11 outside the commutator 15, which requires manual labor and a large amount of manufacturing man-hours. The problem was that it was needed.

The present invention has been made in order to solve the problems of the prior art, and is to: - Arrange a plurality of coil elements continuously formed by one coil wire on the outside of a commutator in a well-balanced manner quickly and reliably. The purpose of the present invention is to provide a method of arranging armature coils for a flat motor that allows the following.

[Means to solve the problem]

The coil arrangement method for an armature for a flat motor of the present invention is a method for arranging a plurality of coil elements continuously formed by two coil wires in a state in which a plurality of coil elements are placed outside a commutator at a predetermined angle and partially overlapped. In the method of arranging the coils of an armature for a flat motor, each of the coil elements is arranged in a radial manner at a predetermined angle, and in this state, each coil element is held,
It is meant to be tilted in the same direction at the same time.

[For production]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, details of the present invention will be described with reference to an embodiment shown in the drawings.

In the method of arranging coils for a flat motor armature according to the present invention, as shown in FIG. As shown in the figure, a plurality of coil elements 37 are arranged on the assembly jig 60 shown in FIG. 3 in a state where they are placed outside the commutator 53 at a predetermined angle and partially overlap. This assembly jig 60 is provided with a cylindrical portion 62 in which a series of bins 61 for locking a plurality of coil elements 37 are arranged.

Note that before the method of the present invention is carried out, the coil elements 37 are placed in a radial state in a conveying jig 39 as shown in FIG. Further, as shown in FIG. 5, the hook 55 of the commutator 53 and the connecting wire 35 of the coil element 37 have already been fused.

FIG. 6 shows details of a coil arranging device for arranging the coil elements 37. This coil arranging device is a housing jig that accommodates each coil element 37 in a radially erected state at a predetermined angle. A transport jig 39 that is
An annular device main body 3 disposed above this transport jig 39
00, a rotation mechanism 310 that rotates the device main body 300 by a predetermined angle, and a rotation mechanism 310 that is arranged at a predetermined angle from the device main body 300 and grips the coil element 37 and that is synchronized with the rotation of the rotation mechanism 310. It has a gripping mechanism 320 that rotates.

The gripping mechanism 320 has a movable claw 321 and a fixed claw 322, and the movable claw 321 is connected to a moving member 323 that is movable by a cylinder 330. The moving member 323 consists of a piston 324 and a cylinder 325, and a spring 326 is fed between them. In addition, the cylinder 32
5 is rotatably attached to the rotation shaft member 340, and
A spring 341 allows it to move back and forth. Then, the piston 324 is connected to the cylinder 330.
Since the spring 341 is weaker than the spring 326, the cylinder 325 can be moved forward while the spring 341 is being compressed.

When the cylinder 325 moves forward by a predetermined length, the stopper 327 provided on the outside comes into contact with the protrusion 341 of the rotary wheel member 340 and stops its movement. Further, when a force by cylinder 330 is applied to piston 324, spring 326
is compressed, and the movable pawl 321, which is pivoted to the piston 324 via the pin 329, moves around the pin 328, which is pivoted to the fixed pawl 322, as shown by the two-dot chain line in FIG. Move to the side.

On the other hand, the rotation shaft member 340 has a spherical body 302 provided on a rond 301 protruding from the device main body 300 through a notch 342.
They are connected by being rotatably fitted inside.

Further, the device main body 300 is provided with an arc-shaped notch 303, and this notch 303 has a rotation shaft member 3.
A bottle 343 provided at 40 is fitted.

Furthermore, a rotation mechanism 310 whose one end is fixed to a base is attached to the apparatus main body 300.

This rotation mechanism 310 is constituted by a cylinder 311, and rotates the device main body 300 by a predetermined angle.

In the above-described coil arrangement device, first, the coil element 37 is placed in a predetermined position of the device.
The conveyance jig 39 is arranged in a radially erected state so that the connection line 35 is on the center side.

Thereafter, each gripping mechanism 320 arranged at a predetermined angle on the annular device main body 300 arranged above the transport jig 39 is activated. In each gripping mechanism 320, a cylinder 330 pushes a piston 324 toward the coil element 37. As a result, the spring 326 is compressed, and the cylinder 323 is advanced until the stopper 327 comes into contact with the protrusion 341. Then, the stopper 327
41, the spring 326 is then compressed, the movable claw 321 is moved to the position indicated by the chain double-dashed line in FIG. do. Thereafter, the transport jig 39 is lowered and removed from the apparatus. Next, the cylinder 311 of the rotation mechanism 310 extends and the device main body 30
0 by a predetermined angle. Along with this, the rotating shaft member 340 rotates while advancing the bin 343 through the notch 303, and simultaneously tilts the coil element 37 in the same direction to bring it into a horizontal state. After that, the assembly jig 60 was inserted into the position where the transport jig 39 had been set, and then each of the horizontally oriented coil elements 37 was placed in the cylindrical part 62 of this assembly jig 60. The assembly jig 60 is raised so that it is locked to the plurality of bins 61 . Then, the gripping mechanism 320 pulls the cylinder 330, and the movable claw 3
21 is released, and the moving member 323 is returned to its original position by the spring 326. Thereafter, the cylinder 311 of the rotation mechanism 310 returns to its original position. After that, force is applied to each coil element 37 and the assembly jig 60
Each coil element 37 that is about to rise by the spring bank is adapted to the assembly jig 60.

Finally, these are fixed with resin in this state.

However, in the coil arrangement method of the flat motor armature configured as described above, each coil element 3
7 are arranged in a radial manner at a predetermined angle,
In this state, each coil element 37 was held and tilted in the same direction at the same time, so that the plurality of coil elements 37 continuously formed by - coil wires e were
It becomes possible to quickly and reliably arrange them in a well-balanced manner on the outside of the commutator 53.

In other words, since each coil element 37 is tilted in the same direction at the same time, it is no longer possible to place an example of the coil element at the end of the assembly on the coil element at the beginning of the assembly, as in the conventional case. , it becomes possible to arrange the coil elements in a well-balanced manner.
