본 고안은 스테핑 모터(Stepping Motor)의 로터(Rotor)구조에 관한 것으로 특히 로터를 구성하는 마그네트(Magnet)와 칼라(Collar)를 결합하는데 있어서 칼라(Collar)의 외연에 상측에서 하측으로 순차로 크기가 다른 환형 돌기를 형성하여 접착제의 의부 유출을 방지시켜 접착제의 손실을 방지하고 접착강도를 향상토록 한것이다.The present invention relates to a rotor structure of a stepping motor, and in particular, in the coupling of a magnet and a collar forming the rotor, the size is sequentially from the upper side to the lower side on the outer edge of the collar. It is to prevent the loss of adhesive and improve the adhesive strength by forming different annular projections.

종래에는 스테핑모터의 로터를 구성함에 있어서, 첨부도면 제 1 도에 도시된 바와같이 샤프트(1)에 칼라(2)를 삽착하고 칼라(2)외연에 형성된 요홈(2b)에 접착제를 채워서 마그네트(3)를 상기 칼라(2)에 삽입하여 접착제가 마그네트(3)와 칼라(2)를 일체로 접착토록 하였다.Conventionally, in configuring a rotor of a stepping motor, as shown in FIG. 1 of the accompanying drawings, the collar 2 is inserted into the shaft 1 and the grooves 2b formed on the outer edge of the collar 2 are filled with an adhesive to form a magnet ( 3) was inserted into the collar 2 so that the adhesive bonds the magnet 3 and the collar 2 integrally.

이와같은 종래의 스태핑모터의 로터구조에서는 마그네트(3)와 칼라(2)를 조립할 때 칼라(2)외연에 도포되는 접착제가 외부로 유출되어 다른 구동부를 접착시키는 예가 종종 발생하였으며 이를 방지하기 위하여 칼라(2)와 마그네트(3) 사이의 간극을 최소화 하면 접착제가 균일하게 도포되지 않아 접착강도가 떨어지면서 칼라 마그네트가 분리되는 고장을 종종 발생하였으며 접착제의 낭비 또한 많았던 것이 허다한 현실정이었다.In the rotor structure of the conventional stepping motor as described above, when assembling the magnet 3 and the collar 2, an adhesive applied to the outer edge of the collar 2 often leaks to the outside to bond other driving parts. Minimizing the gap between (2) and the magnet (3), because the adhesive is not evenly applied, the failure of the color magnet is separated due to the drop in adhesive strength, and the waste of adhesive was also a lot of reality.

본 고안은 상기한 종래의 재결합을 감안하여 칼라 외연에 상측에서 하측으로 순차로 크기가 다른 환형돌기를 형성하여 접착제의 유출을 방지하고 접착제가 고르게 도포되어, 칼라와 마그네트를 더욱 완벽하게 접착하면 서로 작업이 간편하게 함을 목적으로 한 것으로 첨부도면 제 2 도에 의거 상세히 설명하면 다음과 같다.The present invention prevents the outflow of the adhesive by applying annular projections of different sizes sequentially from the upper side to the lower side on the outer edge of the collar in consideration of the conventional recombination described above. When the operation is for the purpose of simplicity and described in detail with reference to the accompanying drawings 2 as follows.

샤프트(1)에 축착되어 마그네트(3)를 결합하는 칼라(2)의 외연에 환경돌기(2a)를 형성하되 다단 피라밋형으로 상측으로 하측으로 순차로 크게하여 마그네트(3)와 결합시 최하단의 환형돌기(2a)가 마그네트(3) 내벽에 밀착되어 저부를 밀폐시킴으로써 접착제가 흘러나오지 못하게 한것이다.The environmental projection 2a is formed on the outer edge of the collar 2 which is fixed to the shaft 1 and couples the magnet 3, but is multistage pyramid-shaped and is enlarged in order from the top to the bottom in order to be the lowest at the time of coupling with the magnet 3. The annular projection 2a is in close contact with the inner wall of the magnet 3 to seal the bottom so that the adhesive does not flow out.

이와같이 구성된 본 고안을 다시한번 상세히 설명하면, 샤프트(1)는 비자성체의 재질로 구성되어 칼라(2)의 중심에 천설된 결합공(2´)에 억지 끼워 맞춤이 되며, 끝단부분은 라운드 형상으로 되어서 회전이 용이하게 구성되어 있으며 상기 샤프트(1)에 결합되는 칼라(2)는, 연질 알미늄으로 구성되어, 상측은 접착제 도포시 접착제의 유입을 원활하게 하기 위하여 계란형으로 라운드(Round)를 형성하고 그 외연에 3단으로 형성된 환형돌기(2a)는 상측부분에서부터 순차로 커져서 전체의 구성이 피라밋 형상을 이루어 최하단의 환형돌기(2a)는 마그네트(3)와 결합시 마그네트(3) 내벽에 밀착되도록 구성되어 있다.Referring to the present invention configured in this way again in detail, the shaft (1) is made of a non-magnetic material and is forcibly fitted in the coupling hole (2 ′) installed in the center of the collar (2), the end portion is a round shape It is configured to be easily rotated and the collar (2) coupled to the shaft (1) is made of soft aluminum, the upper side to form a round (Round) in the shape of an egg to facilitate the inflow of the adhesive when the adhesive is applied And the annular projection (2a) formed in three stages on the outer edge is increased in sequence from the upper side to form a pyramid shape of the entire configuration, the lowermost annular projection (2a) is in close contact with the inner wall of the magnet (3) when combined with the magnet (3) It is configured to be.

이와같이 구성된 칼라(2)에 마그네트(3)를 위에서 아래로 끼우는 식으로 결합하여 마그네트(3)와 칼라(2)사이에 접착제를 흘려 넣으면 칼라(2)의 최하단 환형돌기(2a)가 마그네트(3)의 내면에 밀착되어 밀폐됨으로써 접착제는 외부로 유출되지 않고 칼라(2)와 마그네트(3) 사이에 적당량이 채워지게 되는 것이다.When the magnet 3 is inserted into the collar 2 configured in this manner from the top to the bottom, and an adhesive is poured between the magnet 3 and the collar 2, the lowermost annular projection 2a of the collar 2 is the magnet 3. By being sealed in close contact with the inner surface of the c), an appropriate amount is filled between the collar 2 and the magnet 3 without spilling to the outside.

상기한 바와같이 본 고안은 칼라와 마그네트 사이에 상측에서 하측으로 순차로 커지는 구성을 하여 최하단은 밀폐되어 있으므로 접착제가 유출되지 않음은 물론 고르게 도포되어 작업불량이나 접착불량이 발생되지 않을 뿐만 아니라 작업이 보다 손쉬운 매우 유용한 고안이다.As described above, the present invention has a configuration that increases sequentially from the top to the bottom between the collar and the magnet, so the bottom end is sealed, so that the adhesive does not leak, and evenly applied, there is no work defect or poor adhesion, and work is not performed. It is a very useful design easier.
