본 발명은 광섬유 모재 회전을 통해 광섬유 진원도를 개선하는 광섬유 인선 장치 및 이를 이용한 광섬유 인선 방법에 관한 것이다.The present invention relates to an optical fiber edge device for improving the optical fiber roundness through the rotation of the optical fiber base material and an optical fiber edge method using the same.

변형된 화학적 증착법(MCVD, Modified Chemical Vapor Deposition)이나 외부 기상 증착법(OVD, Outside Vapor Deposition) 또는 기상축 증착법(VAD, Vapor axial deposition)등에 의해 제조된 광섬유 모재(optical fiber preform)는 인선 과정(drawing process)을 거치게 되는데, 통상적으로 지지대(feeder, 또는 draw tower), 가열로(furnace), 직경측정기, 코팅기, UV램프, 직경측정기, 캡스턴 및 스풀등을 지나게 된다.Optical fiber preforms produced by Modified Chemical Vapor Deposition (MCVD), Outside Vapor Deposition (OVD), or Vapor Axial Deposition (VAD) are used for drawing. process, typically through a feeder or draw tower, furnace, diameter gauge, coater, UV lamp, diameter gauge, capstan and spool.

열원으로서 가열로는 주로 전기저항로, 고주파유도로 및 이산화탄소 레이저 등이 사용된다. 이 과정은 불순물에 의해 광섬유 표면이 오염되어 강도가 저하되지 않도록 정결한 분위기가 필요하다.As the heat source, a heating furnace is mainly used an electric resistance furnace, a high frequency induction furnace, and a carbon dioxide laser. This process requires a clean atmosphere so that the surface of the optical fiber is contaminated by impurities and the strength is not lowered.

인선하는 동안 레이저 마이크로 측정기 같은 정확한 장치로 계속 측정하여 즉시 광섬유에 1차 코팅을 한다. 이 코팅은 광섬유를 심하게 열화시키는 습도, 마모 등으로부터 광섬유를 보호하는 역할을 한다. 여기에 쓰이는 적합한 코팅 재료에는 카이너(Kynar), 에폭시, 실리콘 RTV, UV경화수지가 있다. 2차 코팅은 가끔 감는 작업중에 실시하여 쿠션을 향상시킴으로써 부스러짐에 대한 저항도를 높인다.During cutting, the instrument is continuously measured with an accurate device, such as a laser micrometer, to immediately coat the optical fiber with a primary coating. This coating serves to protect the fiber from humidity, abrasion, etc., which severely degrades the fiber. Suitable coating materials used here include Kynar, epoxy, silicone RTV, and UV curable resins. Secondary coatings are carried out during occasional winding operations to increase the resistance to breakage by improving cushioning.

제작된 모든 광섬유는 최소 장력 요건을 만족하는지 시험한다. 이 시험은 코팅을 한 후 감는 작업중이나 혹은 인선과정 뒤의 독립적인 절차로 실행한다.All fabricated optical fibers are tested to meet minimum tension requirements. This test is carried out as an independent procedure during the winding and after the coating or after the cutting process.

한편, 광섬유의 진원도(circularity) 특성은 광섬유 품질에 영향을 주는 인자중의 하나로서, 상기 광섬유의 진원도는 광섬유 모재의 진원도와 직접적으로 연관성을 갖는다.Meanwhile, the circularity characteristic of the optical fiber is one of factors affecting the optical fiber quality, and the circularity of the optical fiber is directly related to the roundness of the optical fiber base material.

이러한 광섬유 모재의 진원도는 원튜브의 경우 양호하지만 MCVD 증착, 콜랩스 공정, RIT(Rod In Tube)공정 중에 자중 및 온도 불균일등 여러가지 원인으로 인하여 진원도가 원하는 정도를 벗어나게 되어 결국 광섬유의 진원도를 저해한다.The roundness of the optical fiber base material is good in the case of the one tube, but due to various factors such as self-weight and temperature unevenness during the MCVD deposition, the collabs process, and the rod in tube (RIT) process, the roundness is out of the desired degree, and thus the roundness of the optical fiber is impaired. .

이를 향상시키기 위해, 인선 과정에 있어서, 가능한 한 일정한 직경의 광섬유가 만들어지도록 설계하면 광섬유 감쇠를 최소화하고, 광손실로 인한 품질 저하를 막으며, 장력을 높이고 또한 정확한 직경제어를 통해 광섬유 연결시 손실이 낮도록 설계된 정밀 커넥터를 사용하기가 용이하다.To improve this, in the process of cutting, designing the fiber to be as constant diameter as possible can minimize the fiber attenuation, prevent the quality loss due to light loss, increase the tension, and control the loss of fiber connection through accurate diameter control. This low-precision precision connector is easy to use.

도 1은 종래의 광섬유 인선 장치중 지지대와 가열로(80) 부분을 나타내는 개략도이다. 도 1에 도시된 바와 같이 종래의 광섬유 인선 장치는 광섬유 모재(10)가 고정되는 척(20), 척(20)의 전후방향 이송수단(30), 척(20)의 좌우방향 이송수단(40), 전후방향 이송수단(30)과 좌우방향 이송수단(40)을 장착한 지지부(60), 지지부(60)의 측면에 장착되어 지지부(60)를 상하방향으로 이송하는 상하방향 이송수단(50) 및 상하방향 이송수단(50)이 고정 설치된 설비 프레임으로 구성된 지지대와 가열로(80)를 나타낸다.1 is a schematic view showing a portion of a support and a heating furnace 80 in a conventional optical fiber cutting apparatus. As shown in FIG. 1, a conventional optical fiber cutting line device includes a chuck 20 to which an optical fiber base 10 is fixed, a forward and backward transfer means 30 of the chuck 20, and a left and right transfer means 40 of the chuck 20. ), The support unit 60 equipped with the front and rear conveying means 30 and the left and right conveying means 40, and the vertical conveying means 50 mounted on the side of the support 60 to convey the support 60 in the vertical direction. ) And a support and heating furnace 80 consisting of a plant frame fixed to the vertical conveying means 50 is installed.

현재 지지대에서 일반적으로 적용중인 광섬유 모재 고정용 척은 광섬유 모재를 고정한 상태로 전후 및 좌우 방향으로만 이동하는 시스템으로 되어 있다. 이는 인선 과정중에 발생하는 광섬유 모재와 각종 장치 사이의 정렬을 맞추기 위한 것으로 광섬유 모재의 센터가 제조공정중에 발생하는 변형에 의하여 항상 일정하지 않기 때문에 이를 보정하기 위해 필요한 장치이다.The optical fiber base material fixing chuck currently applied in the support is a system that moves only in the front and rear and left and right directions with the optical fiber base material fixed. This is to adjust the alignment between the optical fiber base material and the various devices generated during the cutting process and is necessary to compensate for this because the center of the optical fiber base material is not always constant due to the deformation occurring during the manufacturing process.

그런데 광섬유 모재의 진원도가 유지되는 상태에서 단순하게 센터의 정렬만 틀어진 경우에는 기존의 전후 및 좌우 이송만 실시하여도 문제를 해결할 수 있으나, 광섬유 모재의 진원도가 상기한 바와 같이 까지 증착공정등을 거치면서 틀어진 경우에는 전후 및 좌우 이송만으로는 부족하다. 따라서 이를 개선하기 위한 방법의 개발이 예의 요구되어 왔다.However, if the alignment of the center is simply misaligned while the roundness of the optical fiber base material is maintained, the problem may be solved by only performing the forward, rearward, left and right transfer. In case of twisting, it is not enough to move forward and backward and left and right alone. Therefore, the development of a method for improving this has been demanded.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로,Therefore, the present invention has been made to solve the above problems,

본 발명의 목적은 광섬유 모재(100)에 회전을 부여하여 궁극적으로 광섬유에 꼬임을 가함으로써 광섬유의 진원도 저하에 따른 영향을 최소화하기 위한 광섬유 모재 회전을 통해 광섬유 진원도를 개선하는 광섬유 인선 장치 및 이를 이용한 광섬유 인선 방법을 제공하는 것이다.An object of the present invention is to give a rotation to the optical fiber base material 100 and ultimately to twist the optical fiber by the optical fiber edge device to improve the optical fiber roundness through the rotation of the optical fiber base material to minimize the effect of the roundness of the optical fiber It is to provide a fiber optic edge method.

이러한 본 발명의 목적은, 광섬유 인선 장치중 지지대(미도시)에 있어서, 척의(200) 전후방향 이송수단(300) 또는 좌우방향 이송수단(400)의 하부에 장착되는 회전수단(900)을 포함하는 광섬유 모재 회전을 통해 광섬유 진원도를 개선하는 광섬유 인선 장치에 의해 달성된다.An object of the present invention, in the support (not shown) of the optical fiber cutting apparatus, the chuck 200 includes a rotating means 900 mounted to the front and rear conveying means 300 or the lower portion of the lateral conveying means 400. It is achieved by the optical fiber edge device to improve the optical fiber roundness through the optical fiber base material rotation.

또한 본 발명의 목적은, 광섬유 모재(100)의 직경 및 길이에 따라 척(200)의 회전수단(900)의 회전수를 결정하는 단계 및 상기 회전수에 따른 척(900)의 회전으로 광섬유 모재(100)를 회전하는 단계를 포함하는 광섬유 모재 회전을 통해 광섬유 진원도를 개선하는 광섬유 인선 방법에 의해 달성된다.In addition, an object of the present invention, the optical fiber base material by the step of determining the rotational speed of the rotating means 900 of the chuck 200 according to the diameter and length of the optical fiber base material 100 and the rotation of the chuck 900 according to the rotational speed It is achieved by the optical fiber edge line method to improve the optical fiber roundness through the optical fiber base material rotation comprising rotating (100).

도 2는 본 발명의 일실시예에 따른 광섬유 인선 장치중 지지대(미도시)와 가열로(800) 부분을 나타내는 개략도이다.Figure 2 is a schematic diagram showing a portion of the support (not shown) and the heating furnace 800 of the optical fiber cutting apparatus according to an embodiment of the present invention.

본 발명의 일 실시예에 따른 광섬유 인선 장치중 지지대(미도시)는 광섬유 모재(100)를 고정하는 척(200)의 상단부에 회전수단(900)이 장착되고, 상기 회전수단(900)은 척(200)의 전후방향 이송수단(300)의 하부에 고정되며, 상기 전후방향 이송수단(300)의 상부에 척(200)의 좌우방향 이송수단(400)이 장착되고, 상기 좌우방향 이송수단(400)은 지지부(600)의 하부에 장착되고, 상기 지지부(600)를 상하방향으로 이송하는 상하방향 이송수단(500)이 지지부(600)의 측면에 장착되고, 상기 상하방향 이송수단(500)은 설비 프레임에 고정된다.The support (not shown) of the optical fiber cutting apparatus according to an embodiment of the present invention is equipped with a rotating means 900 at the upper end of the chuck 200 for fixing the optical fiber base material 100, the rotating means 900 is a chuck It is fixed to the lower portion of the front and rear conveying means 300 of the 200, the left and right conveying means 400 of the chuck 200 is mounted on the upper and rear conveying means 300, the left and right conveying means ( 400 is mounted to the lower portion of the support 600, the vertical conveying means 500 for transporting the support 600 in the vertical direction is mounted on the side of the support 600, the vertical conveying means 500 Is fixed to the installation frame.

회전수단(900)은 척(200)을 미리 설정된 회전수에 따라 회전하며, 전후방향 이송수단(300)과 좌우방향 이송수단(400)의 전후 및 좌우 이송에 연동한다.The rotating means 900 rotates the chuck 200 according to a preset rotational speed, and interlocks with the front, rear, left and right conveying means of the front and rear conveying means 300 and the left and right conveying means 400.

상기 회전수단은 모터로 구성되고, 모터의 회전수를 제어하는 제어수단(미도시)이 상기 모터에 유선 또는 무선방식으로 전기적으로 연결되는 것이 바람직하다.The rotating means is composed of a motor, it is preferable that the control means for controlling the number of revolutions of the motor (not shown) is electrically connected to the motor in a wired or wireless manner.

본 발명에 따른 광섬유 인선 방법은 광섬유 모재(100)의 직경 및 길이에 따라 척(200)의 회전수단(900)의 회전수를 결정하고 이에 따른 척(900)의 회전으로 광섬유 모재(100)를 회전하는 단계가 포함된다.In the optical fiber cutting method according to the present invention, the rotation speed of the rotating means 900 of the chuck 200 is determined according to the diameter and the length of the optical fiber base material 100, and thus the optical fiber base material 100 is rotated by the rotation of the chuck 900. Rotating is included.

광섬유 모재(100)의 제조과정중에 변형이 발생한 경우 광섬유 모재(100)의 회전수를 크게 하면 진동이 발생할 가능성이 있다. 또한 광섬유 모재(100)의 센타정렬을 위해 인선 과정중 계속적인 전후 및 좌우 이송이 일어나기 때문에 회전수단(900)과 이송장치간에 공진이 발생할 수 있다.When deformation occurs during the manufacturing process of the optical fiber base material 100, when the rotation speed of the optical fiber base material 100 is increased, vibration may occur. In addition, since the front, rear, left and right transfer is continuously performed during the cutting process for center alignment of the optical fiber base material 100, resonance may occur between the rotating means 900 and the transfer device.

따라서 광섬유 모재(100)의 회전수를 결정하기 위하여 광섬유 모재(100)의 직경 및 길이를 몇가지로 분류한 후 각각의 경우에 대하여 수치해석을 통해 진동특성을 해석한 후 진동에 의한 영향을 최소화할 수 있는 회전수를 선정한다. 다만, 회전수의 결정시 광섬유 모재(100)의 변형이 심할 경우에는 전후 및 좌우 이송량에 따른 영향만을 고려하여 회전수를 결정한다.Therefore, in order to determine the rotation speed of the optical fiber base material 100, the diameter and length of the optical fiber base material 100 are classified into several types, and the vibration characteristics are analyzed through numerical analysis for each case, and then the influence of vibration is minimized. Select the number of revolutions. However, if the deformation of the optical fiber base material 100 is severe when determining the number of revolutions, the number of revolutions is determined in consideration of only the influence of the front, rear, left and right feeding amount.

바람직한 일예로서 품질이 양호한 450km 실리콘 싱글 모드 프리폼의 경우 약 5~30rpm 범위에서 회전수를 선정하는 것이 바람직하다. 상기 프리폼의 경우에 5rpm미만인 경우 모재 회전의 효과가 떨어지고, 30rpm을 초과하는 경우는 진동이 지나치게 커지게 되어 바람직하지 않다.As a preferred example, in the case of good quality 450km silicon single mode preform, it is desirable to select the rotation speed in the range of about 5 to 30 rpm. In the case of the preform is less than 5rpm, the effect of the base material rotation is lowered, if it exceeds 30rpm vibration is too large is not preferable.

본 발명의 바람직한 일실시예에서, 모터로서는 정속모터를 사용할 수도 있고, 서보모터, 브러쉬 리스 DC 서보모터, 스탭핑모터등의 정밀 제어가 가능한 모터를 사용할 수 도 있으나 상기한 예에 한정되는 것은 아니다.In a preferred embodiment of the present invention, a constant speed motor may be used as the motor, or a motor capable of precise control such as a servo motor, a brushless DC servomotor, and a stepping motor may be used, but is not limited thereto. .

본 발명의 변형예로서 모터에는 제어수단(미도시)이 연결되는 대신 모터의 회전수를 감소하는 감속장치가 장착될 수 있다.As a modification of the present invention, the motor may be equipped with a deceleration device for reducing the number of revolutions of the motor instead of the control means (not shown).

본 발명에 따라 광섬유 모재(100) 제조공정중에 발생하는 광섬유 모재(100)의 진원도 불량에 기인하는 광섬유의 품질 저하를 최소화할 수 있으며, 안정적으로 광섬유를 생산함으로써, 생산성 향상에 기여하게 된다. 특히 광섬유 모재(100)의변형이 심하지 않고 다만 진원도 특성이 저하된 광섬유 모재(100)의 경우 별도의 처리공정을 거치지 않고서도 광섬유의 품질저하를 최소화할 수 있다.According to the present invention, it is possible to minimize the deterioration of the quality of the optical fiber due to poor roundness of the optical fiber base material 100 generated during the manufacturing process of the optical fiber base material 100, and contribute to productivity improvement by stably producing the optical fiber. In particular, in the case of the optical fiber base material 100 in which the deformation of the optical fiber base material 100 is not severe and the roundness characteristics are reduced, the quality deterioration of the optical fiber can be minimized without a separate treatment process.

또한 본 발명은 광섬유 모재(100)를 소정 속도로 회전시키는 방법을 적용함으로써 궁극적으로 광섬유에 꼬임을 가하는 것으로, 종래 광섬유에 꼬임을 가하는 방법이 불필요한 벤딩 모멘트나 진동을 발생시키는 것과는 달리 광섬유 모재(100)에 직접 꼬임을 가하여 불필요한 진동을 최소 한도로 억제하고, 불필요한 진동 발생 억제를 위한 추가적 수단의 구비를 배제할 수 있다.In addition, the present invention by applying a method for rotating the optical fiber base material 100 at a predetermined speed ultimately to twist the optical fiber, unlike the conventional method of applying a twist to the optical fiber to generate unnecessary bending moment or vibration optical fiber base material 100 ) Can be directly twisted to suppress unwanted vibrations to a minimum and to eliminate the need for additional means for suppressing unnecessary vibrations.

비록 본 발명이 상기 언급된 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정이나 변형을 하는 것이 가능하다. 따라서 첨부된 특허청구의 범위는 본 발명의 요지에서 속하는 이러한 수정이나 변형을 포함할 것이다.Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention. Accordingly, the appended claims will cover such modifications and variations as fall within the spirit of the invention.
