본 발명은, 전기기기나 통신기기등에 사용되는 적층감기코일, 즉 코어에 코일용 선재와 절연용 필름을 교호로 감아서 이루어진 적층감기코일의 형성방법 및 그 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of forming a laminated winding coil and an apparatus thereof, which are formed by alternately winding a coil winding wire and an insulating film on a core, that is, a coil used for an electric device or a communication device.
예를 들면, 브라운관 등에 사용되는 프라이백트랜스에는, 코어에 코일용 선재와 절연용 필름을 교호로 감아붙인 적층감기코일이 사용되고 있다.For example, a laminated winding coil in which a coil wire and an insulating film are alternately wound on a core is used for a flyback transformer used in a CRT or the like.
종래의 적층감지코일의 일예를 제4도를 참조해서 설명하면, 코어(2)에 절연용 필름(3)을 1층 감고, 이 절연용 필름(3) 위에 그 양옆가장자리로부터 적당한 거리를 띠운 범위에 코일용 선재(20)를 감아서 안쪽코일(21)을 형성하고, 그 위에 절연용 필름(3)을 3층으로 감고, 그 위에 상기와 마찬가지로 코일용 선재(20)를 감아서 바깥쪽코일(22)을 형성하고, 그 위에 절연용 필름(3)을 1층 감고, 그 후 수지밀봉해서 구성되어 있다.An example of a conventional laminated sensing coil will be described with reference to FIG. 4, where a single layer of insulating film 3 is wound around the core 2, and an appropriate distance is provided from the side edges on the insulating film 3. Winding the coil wire 20 to form an inner coil 21, wound the insulating film 3 in three layers thereon, and wound the coil wire 20 to the outer coil on it as described above (22) is formed, the insulating film 3 is wound up one layer, and resin sealing is carried out after that.
그러나, 이와 같은 적층감기코일에서는 안쪽코일(21)와 바깥쪽코일(22)의 옆가장자리 사이의 절연거리(파선으로 표시한)(23)이 짧아, 절연특성이 불량하다고 하는 문제가 있었다.However, such a laminated winding coil has a problem that the insulation distance (indicated by broken lines) 23 between the inner edge of the inner coil 21 and the outer edge of the outer coil 22 is short, resulting in poor insulation characteristics.
그래서, 제3도에 표시한 바와 같이, 안쪽코일(21)와 바깥쪽코일(22)사이에 감게 되는 3층의 절연용 필름(3) 중에서, 중간층의 절연용 필름(3a)의 폭을 좁게 하므로서, 파선으로 표시한 절연거리(24)를 길게해서, 절연특성의 향상을 도모하는 것을 고려할 수 있다.Therefore, as shown in FIG. 3, in the three-layer insulating film 3 wound between the inner coil 21 and the outer coil 22, the width of the insulating film 3a of the intermediate layer is narrowed. Therefore, it is possible to consider increasing the insulation distance 24 indicated by the broken line to improve the insulation characteristics.
그런데, 종래의 적층감기코일의 형성공정에서는, 절연용 필름(3)은 일정폭으로 절단되어 릴형상으로 감긴 것이 사용되고 있고, 그 때문에 제3도에 표시한 바와 같이, 안쪽코일(21)과 바깥쪽코일(22)사이의 3층의 절연용 필름(3)에 있어서의 중간층의 절연용 필름(3a)로서 폭이 좁은 절연용 필름을 감기 위해서는, 필름릴을 교환하거나, 필름공급장치를 필름릴마다 설치해서 그것을 절환토록 구성할 필요가 있었다.By the way, in the conventional formation process of the laminated coil, the insulation film 3 is cut to a certain width and wound in a reel shape. Therefore, as shown in FIG. 3, the inner coil 21 and the outer coil are used. In order to wind the narrow insulating film as the insulating film 3a of the intermediate layer in the three-layer insulating film 3 between the side coils 22, the film reel is replaced or the film supply device is film reeled. We had to install it every time and configure it to switch.
그러나, 안쪽코일(21)와 바깥쪽코일(22)의 사이에 3층에 절연용 필름(3)을 감는 일련의 공정내에서, 필름폭을 교호로 절환하기 위해서는, 절연용 필름(3)을 감아서 고정한 후, 필름폭을 절환, 다시 감아서 고정한다고 하는 공정을, 필름폭마다 행할 필요가 있어, 작업능률이 나빠지고, 양산에 대처할 수 없다고 하는 문제가 있었다.However, in the series of processes in which the insulating film 3 is wound on three layers between the inner coil 21 and the outer coil 22, in order to alternately switch the film width, the insulating film 3 is removed. After winding and fixing, it is necessary to perform the process of switching and rewinding and fixing the film width for every film width, and working efficiency worsened and there existed a problem that mass production could not be coped.
본 발명은, 상기 종래의 문제점에 비추어, 코일용 선재사이에 필름폭이 다른 절연용 필름을 감을 때 연속해서 감을 수 있는 적층감기코일형성방법 및 그 장치를 제공하는 것을 목적으로 한다.An object of the present invention is to provide a laminated winding coil forming method and an apparatus which can be wound continuously when winding an insulating film having a different film width between coil wires in view of the above conventional problems.
본 발명의 적층감기코일형성방법은, 코어에 절연용 필름와 코일용 선재를 교호로 감는 적층감기코일형성방법에 있어서, 코일용 선재사이에 개입 장치되는 3층 이상의 절연용 필름을 감는 공정에서 그 중간층이 되는 절연용 필름을 감을 때 절연용 필름의 필름폭을 좁게 절단하므로서 내외층으로 되는 절연용 필름과 동일한 절연용 필름을 사용해서 연속해서 감는 것을 특징으로 한다.In the method of forming a laminated winding coil of the present invention, in a laminated winding coil forming method of alternately winding an insulating film and a coil wire rod in a core, the intermediate layer in the step of winding three or more layers of insulation films interposed between the coil wire rods. When winding up the insulating film used, it cuts the film width of the insulating film narrowly, It winds continuously, using the same insulating film as the insulating film used as an inner and outer layer.
또, 본 발명의 적층감기코일형성장치는, 코어유지수단과, 선재감기수단과, 절연용 필름감기수단을 구비하고, 코어에 절연용 필름과 코일용 선재를 교호로 감기도록 한 적층감기코일형성장치에 있어서, 절연용 필름감기수단에 있어서의 절연용 필름의 공급경로에 필름폭을 좁게 절단하는 절단수단을 배설한 것을 특징으로 한다.Further, the laminated winding coil forming apparatus of the present invention includes a core holding means, a wire winding means, and an insulating film winding means, and a laminated winding coil is formed by alternately winding an insulating film and a coil wire for winding to a core. An apparatus comprising: cutting means for narrowly cutting a film width in a supply path of an insulating film in the insulating film winding means.
본 발명의 적층감기코일형성방법에 의하면, 코일용 선재사이에 개입장치되는 3층이상의 절연용 필름을 감는 공정에서 그 중간층이 되는 절연용 필름을 감을 때 필름폭을 좁게 절단하고 있으므로, 중간층이 되는 폭이 좁은 절연용 필름을 내외층과 동일한 절연용 필름을 사용연속해서 감을 수 있고, 절연거리가 긴 적층감기코일에 있어서의 절연용 필름의 감기작업을 능률적으로 행할 수 있어, 양산화가 가능해진다.According to the laminated coil forming method of the present invention, in the step of winding three or more layers of insulating films interposed between the coil wires, the film width is narrowly cut when the insulating film serving as the intermediate layer is wound. The narrow insulating film can be wound continuously using the same insulating film as the inner and outer layers, and the winding operation of the insulating film in the laminated winding coil with a long insulating distance can be efficiently performed, and mass production becomes possible.
또, 본 발명의 적층감기코일형성장치에 의하면, 절연용 필름을 감기직전에 절단수단에 의해 필름폭을 좁게 절단함으로서, 1종의 절연용 필름을 사용해서 복수종류의 폭의 절연용 필름을 연속해서 감을 수 있다.In addition, according to the laminated winding coil forming apparatus of the present invention, the film width is narrowly cut by the cutting means just before winding the insulating film, so that the insulating film having a plurality of types of widths is continuous using one type of insulating film. I can wind it up.
