Abstract

PURPOSE:To shorten a time required for binding and forming armature coils, by using ultraviolet-rays-hardening binder in the binding process of the armature coils. CONSTITUTION:After armature coils AC are wound up with thermal-fusion- welding wires plural times, a plurality of heated and bound unit coils C1, C2, C3,...are regularly arranged in a metallic mold J in disc shapes and are pressure- tightened by the metallic mold J, and at the same time, the both surfaces of the respective unit coils overlapped to each other are coated with ultraviolet- rays-hardening binder UV to the point, and the coated sections are irradiated with ultraviolet rays, for example, by using a mercury lamp Hg, and the respective unit coils C1, C2,...are bound and fixed to form disc-like armature coils AC. As a result, the conventional heating and cooling processes of the metallic mold jigs for heating and binding can be omitted, and a time required for binding and forming the armature coils is shortened.

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.

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.

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.

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.
