る。To explain the conventional manufacturing method for the armature of this type of flat type electric motor, heat-fused wires are wound and heat-bonded to form a single coil, and a plurality of these single coils are arranged in a disc shape in a jig. After heating and fixing, a disc-shaped armature coil is formed, a commutator is placed in the center of the armature coil, and the terminal of the armature coil is connected to this, and then placed in a mold. Then, a resin is injected and filled into the gap around the armature coil, and the armature coil and commutator are integrally molded to produce a disc-shaped armature.
ところで、単コイルを金型治具内に複数個、整列配置し
、加熱固着して円板状電機子コイルを形成する工程にお
いて、金型治具を加熱(150〜200t;)するのに
20〜40分の加熱時間を要すると共に電機子コイルを
金型より離型するのに、金型を40℃程度まで強制冷却
する必要があり、加熱から冷却まで金型1個当り40〜
60分の時間を要し、金型使用回転率の面から非常に生
産性が悪く、加熱冷却の電力消費もコスト高につながる
問題がある。By the way, in the process of arranging a plurality of single coils in a mold jig and heating and fixing them to form a disc-shaped armature coil, it takes 20 to It takes ~40 minutes to heat up the mold, and in order to release the armature coil from the mold, it is necessary to forcefully cool the mold to about 40°C, and the process from heating to cooling takes about 40~40 minutes per mold.
It takes 60 minutes, and there is a problem that productivity is very low in terms of the rotation rate of the mold, and power consumption for heating and cooling also leads to high costs.

減して、コスト低減を計るものである。[Means for Solving the Problems] [Operations] The present invention has been made to solve the above problems, and uses an ultraviolet curable adhesive to adhesively fix a plurality of single coils constituting an armature coil. By omitting the conventional process of heating the mold and heat-bonding the single coils together, it is possible to shorten the armature coil formation time and increase the rotation rate of the mold, which in turn increases productivity. At the same time, it aims to reduce costs by reducing power consumption for heating and cooling.

成形した円板状回転電機子Aを製作することができる。The armature coil AC is made by winding a heat-fused wire several times and then heat-bonding several single coils C1, C2, etc., arranged in a disk shape in a mold (jig) J. At the same time, an ultraviolet curable adhesive (for example, an ultraviolet and heat curable adhesive UV having the components shown in Table 1) is applied to important points on both sides of each single coil where they overlap. This portion is irradiated with ultraviolet light, for example, a mercury lamp Hg of 80 W/cIIl, from a distance of 15 mm for 1 minute to bond and fix each single coil to form a disc-shaped armature coil AC. At this time, in order to cure the adhesive in the areas that were not exposed to ultraviolet rays, heating was performed at approximately 130° C. for 10 minutes to effect hardening and bonding. After placing the commutator CO in the center of the armature coil AC and connecting the armature coil terminal to the commutator, it is placed in a mold (resin mold jig) and placed in the air gap around the armature coil. It is possible to manufacture a disc-shaped rotating armature A that is integrally molded by injecting and filling resin.

低減に寄与する効果大なるものである。As described above, according to the manufacturing method of the present invention, since an ultraviolet curable adhesive is used in the armature coil bonding process, the heating and cooling processes of the mold jig for conventional thermal bonding can be omitted. By significantly shortening the time required to form the armature coil adhesive (by about a minute per machine), the rotation rate of the mold jig, that is, the productivity, is dramatically improved, and at the same time, the heating This has a significant effect of reducing power consumption and contributing to cost reduction.
