Description

접착식 적층 코어부재 제조장치의 접착제 도포방법Adhesive coating method of adhesive laminated core member manufacturing apparatus
본 발명은 모터나 발전기 등의 코어를 제조하는 데 사용되는 코어부재 제조장치의 제어방법에 관한 것으로서, 보다 상세하게는 단위 시트(Sheet)를 이루는 라미나 부재들을 층간 접착시켜서 모터나 발전기 등의 코어(Core)을 위한 적층 코어부재를 제조하는 접착식 적층 코어부재 제조장치의 접착제 도포방법에 관한 것이다.The present invention relates to a control method of a core member manufacturing apparatus used to manufacture a core such as a motor or a generator, and more particularly, to laminate a lamina member constituting a unit sheet between layers to core such as a motor or a generator. It relates to an adhesive coating method of the adhesive laminated core member manufacturing apparatus for manufacturing a laminated core member for (Core).
일반적으로 라미나 부재(Lamina Member)들을 적층하고 이들을 일체화함으로써 제조되는 적층 코어(Laminating Core)는 발전기나 모터 등의 회전자 및 고정자로 사용되며, 상기 적층 코어를 제조하는 방법 즉 상기 라미나 부재를 적층하고 일체로 고정하는 적층 코어 제조방법으로는, 인터록 탭을 이용한 탭 고정법과 용접 예를 들어 레이저 용접을 이용한 웰딩 고정법과 리벳 고정법 등이 알려져 있다.Generally, a laminating core manufactured by laminating and integrating lamina members is used as a rotor and a stator of a generator or a motor, and a method of manufacturing the lamination core, that is, the lamina member As a laminated core manufacturing method of laminating and integrally fixing, a tab fixing method using an interlock tab and a welding fixing method using a welding, for example, laser welding, a rivet fixing method, and the like are known.
상기 탭 고정법은, 대한민국 공개특허공보 제10-2008-0067426호와 제10-2008-0067428호 등의 특허문헌에 적층 코어부재의 제조기술로 개시되어 있는데, 상술한 적층 코어부재 제조방법은 철손(Iron Loss) 문제가 있고, 특히 상기 탭 고정법은 소재 즉 강판의 박판화 추세로 인해 엠보싱(Embossing) 가공이 어려워져서 적층 코어의 제조기술로서의 한계를 보여주고 있다. 상술한 공개특허공보와 하기의 특허문헌에는 여러 종류와 형상의 적층 코어부재가 개시되어 있다.The tab fixing method is disclosed in Korean Patent Laid-Open Publication Nos. 10-2008-0067426 and 10-2008-0067428, and the like, as a manufacturing technology of a laminated core member. Iron Loss), and in particular, the tab fixing method is difficult to embossing due to the trend of thinning of the material, that is, steel sheet, showing a limitation as a manufacturing technology of the laminated core. The above-mentioned Unexamined Patent Publication and the following patent document disclose laminated core members of various types and shapes.
적층 코어 제조의 다른 방식으로는, 라미나 부재들을 접착제로 일체화하는 접착 고정법이 제시되고 있다. 대한민국 공개특허공보 제10-1996-003021호에 상기 접착 고정법이 개시되어 있으며, 대한민국 공개특허공보 제10-1996-003021호에 개시되어 있는 접착 고정법은 상하방향으로 적층되어 있는 라미나 부재의 측면에 접착제를 도포하여 상기 라미나 부재들을 일체화하는 방식이다.Another way of manufacturing a laminated core has been proposed an adhesive fixation method of integrating lamina members with an adhesive. The adhesive fixing method is disclosed in Korean Patent Application Laid-Open No. 10-1996-003021, and the adhesive fixing method disclosed in Korean Patent Application Publication No. 10-1996-003021 is provided on the side of the lamina member laminated in the vertical direction. It is a method of integrating the lamina members by applying an adhesive.
상기 접착 고정법의 다른 방식으로, 라미나 부재의 표면에 접착제를 도포해서 라미나 부재들의 층간을 접착시키는 층간 접착방식이 있다. 상기 층간 접착방식의 적층 코어 제조장치는, 코어 제조용 소재를 향해 접착제를 계속해서 토출하는 노즐 출구에 상기 소재 즉 금속 스트립의 표면을 접촉시켜서 상기 금속 스트립의 표면에 점(Dot) 형태 또는 라인(Line) 형태로 접착제를 전사한다.As another method of the adhesive fixing method, there is an interlayer bonding method in which an adhesive is applied to the surface of the lamina member to bond the interlayers of the lamina members. The laminated core manufacturing apparatus of the interlayer adhesion method has a dot form or a line on the surface of the metal strip by contacting the surface of the material, that is, the metal strip, with a nozzle outlet that continuously discharges the adhesive toward the core manufacturing material. Transfer the adhesive in the form of.
그러나, 상술한 종래의 접착 고정법에서는, 접착제가 노즐 출구의 주변에 퍼져서 정체되거나 넘쳐 흘러서 노즐 출구의 주변 오염과 출구 막힘 등의 문제가 있고, 노즐 출구의 주변에 접착제 협착이 발생하며, 노즐에 대한 잦은 보수작업이 필요하고 접착제의 소비량이 증가한다. However, in the above-described conventional adhesive fixing method, the adhesive spreads around the nozzle outlet and stagnates or overflows, resulting in problems such as peripheral contamination of the nozzle outlet and outlet clogging, and adhesive stenosis occurs around the nozzle outlet. Frequent maintenance is required and adhesive consumption is increased.
그리고, 상술한 문제점들은 접착제 배출 압력 즉 노즐의 압력을 제어하는 데 장애요인이 되며, 결과적으로 접착제 도포량과 도포면적 및 도포위치의 균일한 제어 즉 접착제의 정량 정밀도포에 장애가 되고 경화시간 단축을 저해한다. In addition, the above-described problems are obstacles in controlling the adhesive discharge pressure, that is, the pressure of the nozzle, and as a result, the uniform control of the adhesive coating amount, the coating area, and the application position, that is, the quantitative accuracy of the adhesive is impeded and the curing time is shortened. do.
또한, 상기 노즐 출구의 주변에 접착제가 협착되면, 금속 스트립과 노즐 출구의 근접에 장애 요인이 되어 접착제의 도포가 정확하게 수행되기 어려우며, 고형화된 접착제가 상기 금속 스트립으로 전이되는 경우에는 라미나 부재들의 층간 접착을 방해하고, 결과적으로 적층 코어부재의 층간이 분리되어 제품 불량으로 이어지므로 불량률 증가로 인해 생산성이 악화되고 관리 비용이 증가하는 등의 문제가 초래될 수 있다. In addition, when the adhesive is squeezed around the nozzle outlet, it is a barrier to the proximity of the metal strip and the nozzle outlet, which makes it difficult to accurately apply the adhesive, and when the solidified adhesive is transferred to the metal strip, Since the interlayer adhesion is hindered, and as a result, the interlayer of the laminated core member is separated, leading to product defects, the problem may occur such that productivity is deteriorated due to an increase in defect rate and an increase in management cost.
더 나아가, 종래의 적층 코어 제조방법에서는, 블랭킹 공정을 위한 상형의 승강과 무관하게 노즐에서 접착제가 계속 배출되기 때문에 일정 주기마다 일정량의 접착제를 강판(소재)의 표면에 도포하기 어렵고, 접착제 도포량과 노즐 작동 시간(접착제 도포 타이밍)을 정확하게 제어하기 위해 접착제 공급 압력 즉 노즐 내부의 압력에 대한 정밀한 관리를 필요로 한다.Furthermore, in the conventional laminated core manufacturing method, it is difficult to apply a certain amount of adhesive to the surface of the steel sheet (material) at regular intervals because the adhesive is continuously discharged from the nozzle regardless of the lifting of the upper die for the blanking process. In order to accurately control the nozzle operating time (adhesive application timing), precise control of the adhesive supply pressure, ie the pressure inside the nozzle, is required.
본 발명은 상술한 종래의 문제점을 해결하기 위해 제안된 것으로서, 상형의 승강에 연동하여 일정 타이밍마다 주기적으로 접착제를 배출함으로써 접착제의 정량 정밀도포를 구현할 수 있는 접착식 적층 코어부재 제조장치의 접착제 도포방법을 제공하는 데 그 목적이 있다.The present invention has been proposed to solve the above-described problems, the adhesive coating method of the adhesive laminated core member manufacturing apparatus that can implement the quantitative precision of the adhesive by periodically discharging the adhesive at a predetermined timing in conjunction with the lifting of the upper mold The purpose is to provide.

When the metal strip S is supplied, the pressing member 200 and the punch 310 mounted on the upper die 10 are lowered integrally with the upper die 10 so that the metal strip S Press the top surface.
이때, 상기 금속 스트립(S)은 상기 가압부재(200)에 의해 눌려서 상기 접착제 도포기(100)의 출구를 향해 근접하고, 이에 따라, 상기 금속 스트립(S)의 저면에 접착제가 도포된다.At this time, the metal strip (S) is pressed by the pressing member 200 toward the exit of the adhesive applicator 100, accordingly, the adhesive is applied to the bottom surface of the metal strip (S).
상술한 접착제 도포 공정과 동시에, 접착제 도포 영역의 하류측에서는 상기 가압부재(200)와 동시에 하강하는 펀치(310)에 의해 소재의 블랭킹이 진행되고, 상기 라이네이트홀(400a) 즉 적층 배럴의 내부에서는 블랭킹에 의해 순차적으로 적층되는 라미나 부재들의 일체화 과정이 진행된다. Simultaneously with the adhesive application process described above, blanking of the material proceeds by the punch 310 which descends simultaneously with the pressing member 200 at the downstream side of the adhesive application region. The integration process of the lamina members sequentially laminated by blanking is performed.
상기 적층 배럴(400a)은 상술한 스퀴즈(420)와 접착제 경화기(410), 더 나아가 상기 핀치(440)에 의해 형성되는 통로로서, 상기 라미나 부재(L)들의 적층과 접착제의 경화가 진행되는 통로를 형성한다.The stacking barrel 400a is a passage formed by the squeeze 420 and the adhesive curing machine 410, and furthermore, the pinch 440, and the lamination of the lamina members L and the curing of the adhesive proceed. Form a passage.
그리고, 상기 스퀴즈(420)와 핀치(440)는 상기 적층 배럴을 통과하는 제품 즉 라미나 부재(L)들과 적층 코어부재(C)들을 정렬하며, 상기 접착제 경화기(410)는 고주파 유도에 의해 발생되는 열로 라미나 부재(L)들의 층간에 존재하는 접착제를 경화시킨다.The squeeze 420 and the pinch 440 align the products passing through the lamination barrel, that is, the lamina members L and the lamination core members C, and the adhesive curing machine 410 is formed by high frequency induction. The heat generated hardens the adhesive present between the layers of the lamina members (L).
