Abstract

The method for producing the rotor of a coreless motor makes the treatment of coils easy so that the low quality of coils may be reduced and easiness in arranging rotor parts on dies may make an automation possible. The production process comprises (a) arranging the flat coils (2) at an equal angle, (b) putting a ring-shaped flat board (14) on the center of the arranged coils, (c) fastening the flat board and the coils with adhesives, and (d) moulding the lamination of the flat coils with a resin.

본 발명은 코어레스 모터의 로우터 제조방법에 관한 것이다. 종래의 코어레스 모터는 제1도에 나타낸 것처럼 자성재(磁性材)로서 이루어진 컵형상의 브래킷(1)에 회전체, 즉 3개의 평판형상의 코일(2)을 합성수지 모울드하고, 또한 중심부에 코뮤레이터(3), 불꽃소거용의 평판형상의 기판(4) 및 회전축(5)을 구비한 로우터(6)를 끼워넣어 전기한 브래킷(1)의 저면중심부에 형성한 오일레스 축받이(7)에 회전축(5)을 끼워 넣도록된 것이며, 또한 로우터(6)상부의 브래킷(1)내에 환상으로 된 영구자석판(8)을 배치하고, 그 위에 도시하지 않은 브러시, 절연가이드부재를 배설하여 뚜껑체(9)로서 전기한 브래킷의 개구부를 피복하여 이루어진 것이었다.The present invention relates to a method for manufacturing a rotor of a coreless motor. In the conventional coreless motor, as shown in Fig. 1, a resin-molded rotary body, that is, three flat coils 2, is formed on a cup-shaped bracket 1 made of a magnetic material, and a commu is formed at the center. To the oilless bearing 7 formed in the bottom center of the bracket 1 inserted by inserting the rotor 6 having the radar 3, the flat board 4 for flame erasing, and the rotor 6 having the rotating shaft 5 therein. The rotary shaft 5 is fitted, and the permanent magnet plate 8 having an annular shape is disposed in the bracket 1 on the upper part of the rotor 6, and a brush and an insulation guide member (not shown) are disposed thereon to cover the lid. Covering the opening part of bracket mentioned above as (9) was done.

그런데 상술한 코어레스 모우터에 있어서는, 그로부터(6)가 제2도에 나타낸것처럼 제조공정중에서 평판환상을 이룬 코일(2)의 결선부(2a)를 고정 부착하는 것뿐이었고, 개개의 코일(2)이 자유로운 상태로 되어 있었다. 따라서 이 코일(2)을 합성수지로 모울드하여 로우터(6)로 성형하기 까지는 코일(2)의 선이 풀어지거나 혹은 단선이 되기까지 쉽고, 취급에 있어서도 주의를 하지 않으면 안되었다.By the way, in the above-described coreless motor, only 6 was fixedly attached to the connection part 2a of the coil 2 which formed the annular plate in the manufacturing process, as shown in FIG. 2) was free. Therefore, until the coil 2 is molded with a synthetic resin and molded into the rotor 6, the coil 2 is easily disconnected or disconnected, and care must be taken in handling.

본 발명의 목적은 상술한 종래기술의 문제점을 제거하고 로우터를 제조할 때 코일의 취급을 용이하게 하여 불량성을 없애고, 작업성을 향상시킬 수 있는 코어렉스모터의 로우터 제조방법을 제공하는 데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide a method for manufacturing a rotor of a Correx motor, which eliminates the problems of the prior art and facilitates handling of a coil when manufacturing the rotor, thereby eliminating defects and improving workability.

이러한 목적을 달성하기 위하여 본 발명은 로우터를 구성하는 복수의 평판형상코일을 평판을 개재시켜 미리 고정하고, 그 다음, 전기한 코일의 결선부를 남기고 코일과 평판을 수지로서 모울드 하는 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that the plurality of flat coils constituting the rotor are fixed in advance via a flat plate, and then the coil and the flat plate are molded as resins, leaving the connection portions of the coils described above.

이어서, 본 발명의 가장 좋은 실시예를 제3도와 제4도에 따라 설명하면 다음과 같다. 즉, 로우터를 구성하는 3개의 평판형상의 코일(2)을 거의 동등한 각도를 갖게하여 배치하고, 이들의 코일(2)의 중앙부에 환상의 펑판(4)을 배설하며, 이 평판(4)과 전기한 3개의 코일(2)과 접착제를 이용하여 고정한다. 그리고 환상의 평판(4)의 중앙구멍(4a)(제3도참조)에서 각 코일(2)의 결선부(2a)를 도출시킨다.Next, the best embodiment of the present invention will be described with reference to FIG. 3 and FIG. That is, the three flat coils 2 constituting the rotor are arranged at substantially equal angles, and an annular flat plate 4 is disposed in the center of these coils 2, and the flat plate 4 and It is fixed using the three coils 2 mentioned above and an adhesive agent. And the connection part 2a of each coil 2 is guide | induced from the center hole 4a (refer FIG. 3) of the annular flat plate 4. As shown in FIG.

전기한 평판(4)에는 철제로된 와셔, 규소강판, 일반적인 기판, 알루미늄판재 혹은 바리스터(Varistor)라 호칭되는 것이 사용되며, 접착제로서는 일반적인 접착제를 사용하는 외에 양면 접착테이프를 평판(4)에 부탁시켜 두어도 된다.As the flat plate 4, a washer made of iron, a silicon steel plate, a general substrate, an aluminum plate, or a varistor is used.As a general adhesive, a double-sided adhesive tape is applied to the flat plate 4 as well. You may make it possible.

상술한 바와 같이 코일(2)은 평판(4)으로서 각각 고정되고 있으므로 제조시의 정상상태유지가 용이해지고, 종래처럼 코일선이 풀어진다거나 혹은 단선등의 발생이 없어지며, 코일을 불량하게 하는 원인이 없어지게 되는 것이다.As described above, the coils 2 are fixed as the flat plates 4, so that the steady state in manufacturing can be easily maintained, and as a result, coil wires are not released or disconnection occurs. This will be gone.

또 종래는 로우터(6)를 수지 모울드할때 전기한 코일(2), 회전축(5) 및 본 발명의 평판(4)에 상당하는 부재를 각각 독립한 상태로 성형금형(成型金型)에 배치하거나 또는, 평판(4)에 상당하는 부재를 로우터(6)의 모울드 성형후에 부착하고 있었다. 그런데 본 발명에서는 미리 코일(2)과 평판(4)과는 고정되어 있으며 성형금형에 배치하는 것이 용이하므로 자동화가 매우 용이하게 행하여 진다. 그리고 이와같은 코일(2)과 평판(4)과를 코일(2)의 결선부(2)를 남겨놓고 일체적으로 수지모울드 하므로서 로우터(6)의 제조가 가능한 것이다.Further, conventionally, the coils 2, the rotating shaft 5, and the members corresponding to the flat plate 4 of the present invention, each of which are electric-molded when the rotor 6 is resin-molded, are arranged in a molding die in an independent state. Alternatively, a member corresponding to the flat plate 4 was attached after mold molding of the rotor 6. By the way, in the present invention, the coil 2 and the flat plate 4 are fixed in advance and easy to arrange in the mold, so that the automation is very easy. And the coil 2 and the flat plate 4 and the resin 6 is integrally molded while leaving the connection part 2 of the coil 2, and the manufacture of the rotor 6 is possible.

또, 코일(2)은 제5도에 나타낸 것처럼 각 중앙부의 상면에 요부(凹部)(2b)를 형성하고, 평판(4)을 요부(2b)에 접착재로서 단단하게 부착하여도 되며, 제6도에 나타낸것처럼 프레스 등에 의해서 각 코일(2)의 중앙부상면에 요부(2b)를 형성하도록 각 코일(2)을 절곡하여 요부(2b)에 평판(4)을 접착제로서 단단하게 부착하는 것도 생각할 수 있다.Moreover, the coil 2 may form the recessed part 2b in the upper surface of each center part as shown in FIG. 5, and may attach the flat plate 4 to the recessed part 2b firmly as an adhesive material, and FIG. 6 As shown in the figure, it is also conceivable that the coils 2 are bent so as to form the recesses 2b on the central upper surface of each coil 2 by pressing or the like, and the flat plate 4 is firmly attached to the recesses 2b as an adhesive. have.

이상 설명한 바와 같이 본 발명에 의하면 코일이 보호유지, 취급이 용이하고 코일의 불량이 없어지며, 더구나 자동화가 용이하므로 작업성의 향상을 꾀할 수 있는등 우수한 효과를 나타낼 수 있다.As described above, according to the present invention, the coil can be easily maintained and handled, the defect of the coil is eliminated, and furthermore, the automation is easy, so that the workability can be improved.
