본 발명은 스텝 모우터의 보빈 구조체를 제조하는 방법에 관한 것이다.The present invention relates to a method of manufacturing a bobbin structure of a step motor.

단극 또는 2극 이상의 스텝 모우터에 있어서, 종래에는 비자성체 철심의 단극 또는 2극의 코아를 스텝 모우터의 용도에 따라 원 외주부에 형성되는 방사상 형태로 하거나 원 내부의 중심에 위치하는 형태로 이루어진 여러개의 철편을 겹쳐서 고정하고, 이렇게 형성시킨 코아를 절연 코팅한 후, 가 극마다 코일을 권선하여 제조하였다.In a single-pole or two-pole or more step motor, conventionally, a single pole or a two-pole core of a nonmagnetic iron core is formed in a radial form formed on the outer periphery of a circle according to the use of the step motor, or is formed in a center located inside the circle. Several iron pieces were overlapped and fixed, and the cores thus formed were insulated coated, and then coils were manufactured for each pole.

한편 여기에서 사용되는 스텝모우터의 보빈 구조체는 상기의 비자성체 코아상에 절연 코팅이나 분제도장을 하는 대신 보빈을 사용하여 스텝 모우터의 고정자로 설치되는 비자성체 코아를 둘러싸도록 하는 구성으로서, 종래에는 비자성체 코아를 개별적으로 싸는 구조로 되었으며, 제4도에 도시와 같이 플라스틱재의 사각형 틀로서 이루어진 보빈(1)으로 구성되어 있다. 이 보빈(1)은 그의 중간부에 여러개의 철편을 성충시킨 철심의 코아부를 삽입할 수 있도록 구멍(2)이 형성되어 있으며, 양측면 둘레부에는 보빈(1)의 동체부(4)에 코일을 권선할 수 있도록 플랜지(3)가 형성되어 있다. 또한 플랜지(3)의 어는 한 일측면상에는 코일 도선(5)을 유도하는 유도홈(5')이 세개가 형성되어 있다.On the other hand, the bobbin structure of the step motor used herein is configured to surround the non-magnetic core installed as a stator of the step motor using a bobbin instead of applying an insulating coating or powder coating on the non-magnetic core. Conventionally, a non-magnetic core is individually wrapped, and as shown in FIG. 4, the bobbin 1 is formed as a rectangular frame of plastic material. The bobbin 1 has a hole 2 formed therein so as to insert a core part of an iron core having several iron pieces in its middle part, and a coil is provided on the body part 4 of the bobbin 1 on both side circumferences. The flange 3 is formed so that it can wind up. In addition, three guide grooves 5 'are formed on one freezing side of the flange 3 to guide the coil leads 5.

그러므로 상기와 같이 코아상에 코팅을 한 후 코일을 권선한다면 단락이나 단선의 위험이 있으며, 이를 보호하기 위하여 보빈을 사용하여 미리 코일을 감는 방식이 있었다. 이러한 방식은 성충 철심의 코아부에 코일을 미리 감은 보빈을 다극스텝 모우터의 각극으로 형성시킨 고정자의 돌극(도시 안됨)에 수동이나 반자동으로 일일이 하나씩 끼우고 코일 단자선을 처리하여야 하는 등 작업상 많은 공정을 필요로 하였다.Therefore, if the coil is wound after coating on the core as described above, there is a risk of short circuit or disconnection, and there was a method of winding the coil in advance using a bobbin to protect it. This type of work requires manual or semi-automatic insertion of the bobbin with coils pre-wound in the core of the adult core into the poles of the multi-pole step motor, either manually or semi-automatically, and the coil terminal lines must be processed. Many processes were required.

따라서 이와같은 단점을 해결하도록 본 발명은 다극스텝 모우터의 극수에 따라 성층 철심의 코아를 개별적으로 둘러 싸울 수 있는 여러개의 봉입부를 가지도록 한 상하의 보빈 구조에 관한 것으로, 본 발명의 방법에 따라 제조된 보빈 구조체는 스텝모우터의 고정자 성층 철심의 모양과 동일한 모양으로 원형의 테두리부상에 소정 극수의 봉입부들의 절반부들을 플라스틱으로 일체 주형하여 상하 보빈을 형성하고, 이 상하 보빈의 봉입부에 성충 철심의 코아를 삽입한 후 통상의 권선기에 의하여 각 극마다의 봉입부에 코일을 자동 권선하여 이루어진다.Therefore, the present invention relates to the upper and lower bobbin structure to have a plurality of encapsulation that can individually surround the core of the stratified iron core according to the number of poles of the multi-pole step motor, to solve the above disadvantages, manufactured according to the method of the present invention The bobbin structure has the same shape as that of the stator stratified iron core of the step motor, and the upper and lower bobbins are formed by integrally molding half of the predetermined number of the encapsulation parts with plastic on the circular rim and forming the upper and lower bobbins. After inserting the core of the iron core is made by winding the coil automatically in the encapsulation for each pole by a common winding machine.

본 발명은 상하 보빈을 주형하고, 상하 보빈상에 코아를 삽입한 후 자동 권선기로 코일을 각 극마다 권선하는 단계들로 이루어진다.The present invention comprises the steps of molding the upper and lower bobbin, inserting the core on the upper and lower bobbin and winding the coil for each pole with an automatic winding machine.

그러므로 본 발명은 코아 권선시 단락이나 단선이 없으며, 각 극마다 보빈을 코아부의 돌극에 끼우는 공정을 필요로 하지 않는다.Therefore, the present invention has no short circuit or disconnection during core winding, and does not require a step of fitting the bobbin to the protrusion of the core part for each pole.

본 발명을 첨부 도면에 의거하여 기술하면 다음과 같다.The present invention will be described below with reference to the accompanying drawings.

본 발명의 보빈은 제1도 도면의 보빈 절반부(10)가 상하로 구성되며, 이 보빈 절반부(10)에는 원형의 테두리부(6)가 형성되어 있다. 테두리부(6)에는 테두리의 강성을 높이기 위하여 소정간격마다 두께부(7)가 일체로 형성된다. 또한 테두리부(6)의 하면에는 성층 철심의 상부 코아부(도시 안됨)를 둘러싸는 봉입부(8)가 소정 극수와 동일 갯수로서 일체 형성된다. 봉입부(8)는 성층 코아의 두께부로 연장되는 플랜지(9)부를 갖고 있으며, 그의 전면에는 양측으로 나팔모양의 날개부(11)가 형성되며, 그의 상부로는 코일을 권선할 수 있도록 한 수직 플랜지부(12)가 일체로 형성되어 있다.In the bobbin of the present invention, the bobbin half 10 of FIG. 1 is configured up and down, and the bobbin half 10 has a circular edge 6 formed therein. The edge portion 6 is integrally formed with a thickness portion 7 at predetermined intervals in order to increase the rigidity of the edge. In addition, an encapsulation portion 8 surrounding the upper core portion (not shown) of the stratified core is integrally formed on the lower surface of the edge portion 6 in the same number as the predetermined number of poles. The enclosing portion 8 has a flange 9 portion extending to the thickness of the stratified core, the front side of which is formed with a trumpet-shaped wing portion 11 on both sides, the upper portion of the vertical to enable winding the coil The flange part 12 is formed integrally.

제2도에는 상하의 보빈(10)을 맞추고 그 봉입부(8) 사이에는 코아(13)를 삽입한 상태에서 코일(14)을 감은 상태의 보빈 구조체(100)가 도시되어 있다.FIG. 2 shows the bobbin structure 100 in which the coil 14 is wound while the bobbin 10 is aligned with the upper and lower bobbins 10, and the core 13 is inserted between the sealing portions 8.

제3도는 제2도의 A-A선을 절단한 단면도로서, 상하의 보빈절반부(10)가 겹쳐져 있고 그 사이로는 성층 철심의 코아(3)가 삽입되어 있다. 봉입부(8)의 외측으로는 날개부(11)의 높이 이하로 코일(14)이 권선된다.3 is a cross-sectional view taken along the line A-A of FIG. 2, in which upper and lower bobbin halves 10 overlap each other, and a core 3 of a stratified iron core is inserted therebetween. The coil 14 is wound to the outside of the enclosing portion 8 below the height of the wing 11.

이와같이 본 발명의 제조방법에 따라 제조되는 보빈 구조체(100)는 원형의 테두리부상에 소정 극수의 봉입부들을 일체로 성형하여 이루어진 상하의 보빈절반부(10)를 형성하고, 이 상하 보빈의 봉입부에 성층 철심의 코아를 삽입한 후 권선기에 의하여 각극마다의 플랜지에 코일을 자동 권선하는 방식으로 형성된다.As described above, the bobbin structure 100 manufactured according to the manufacturing method of the present invention forms upper and lower bobbin halves 10 formed by integrally molding a predetermined number of pole-shaped encapsulation portions on a circular edge portion, and the enclosing portions of the upper and lower bobbins. After inserting the core of the stratified iron core, the coil is formed by automatically winding the coil on each flange by the winding machine.
