Description

클린 케이블 타이clean cable tie
본 발명은 클린 케이블 타이에 관한 것으로, 더욱 상세하게는 디스플레이 생산 장비나 반도체 제조설비를 위한 클린룸(clean room)과 같은 작업 공간에서 마찰로 인한 분진이나 파티클(particle) 발생을 최소화할 수 있도록 한 클린 케이블 타이에 관한 것이다. The present invention relates to a clean cable tie, and more particularly, to minimize the generation of dust or particles due to friction in a work space such as a clean room for display production equipment or semiconductor manufacturing equipment. It's about clean cable ties.
디스플레이 및 반도체 공정의 경우 점진적인 소자나 부품, 제품들의 미세화공정에 따라 생산 수율의 중요성이 더욱 확대되어, 클린룸 내 공정에서 분진이나 파티클(particle) 관리의 중요성이 더욱 높아지고 있다. 분진이나 파티클은 디스플레이 및 반도체 공정에서 제품 불량과 직결되는 원인이라 할 수 있다. 도 1에 디스플레이 장비 등에서 확인할 수 있는 파티클 상태('a' 및 'b' 부분)을 나타냈다. In the case of display and semiconductor processes, the importance of production yield is further expanded according to the gradual refinement of devices, parts, and products, and the importance of managing dust or particles in the process in a clean room is increasing. Dust or particles can be said to be directly related to product defects in display and semiconductor processes. 1 shows particle states (parts 'a' and 'b') that can be confirmed in display equipment.
제품 불량 원인을 해소하기 위하여 디스플레이 및 반도체 공정에서 상기한 파티클을 측정하고 이를 처리하는 방안은 존재한다. 문제는 이러한 디스플레이 및 반도체 공정에서 불량 원인인 파티클을 측정하기 위한 장비가 매우 고가이고 검사 시간도 만만치 않다는 것이다. 또 파티클 자체를 측정하는 작업이 매우 힘들다. 예로 1nm 공정에서는 5nm 파티클을 측정해야 하지만, 난이도가 매우 높아 한계가 존재한다. 이와 같이 공정상에서 파티클을 측정하는 방안은 있지만 파티클을 측정하는 작업 자체가 매우 어렵다는 점에서 생산 수율 향상이 긍정적이지 못하였다. In order to solve the cause of product defect, there is a method for measuring and processing the particles in display and semiconductor processes. The problem is that equipment for measuring particles, which is the cause of defects in such display and semiconductor processes, is very expensive and the inspection time is too long. Also, it is very difficult to measure the particle itself. For example, in the 1nm process, it is necessary to measure 5nm particles, but there is a limit because the difficulty is very high. Although there is a method of measuring particles in the process as described above, the improvement in production yield was not positive in that the operation of measuring particles itself is very difficult.
따라서 파티클 발생을 최소화하여 클린룸 내의 오염이나 장비 오염 자체를 최소화하는 선제적인 방안이 필요하다. 예를 들면 다양한 설비 부품 중 파티클을 발생할 수 있는 부품들을 별도 관리하는 방안이다. 이러한 방안은 장비와 클린룸에 유입되는 파티클을 최소화하는 TCM(Total Cleanliness Management) 개념으로 확산하고 있고, 관련 업계에서는 오염을 최소화하거나 장비 오염을 방지하기 위한 장치나 부품을 도입하는 등, 불량율 관리를 사후 측정이 아닌 사전예방에 집중하고 있다. Therefore, there is a need for a preemptive method to minimize the generation of particles to minimize contamination in the clean room or equipment contamination itself. For example, it is a method to separately manage parts that can generate particles among various equipment parts. These measures are spreading to the concept of Total Cleanliness Management (TCM) that minimizes particles entering equipment and cleanrooms. We are focusing on prevention rather than post-measurement.
디스플레이 및 반도체 공정에서 많이 사용되는 케이블 타이(cable tie) 역시 파티클을 유발하는 부품이라 할 수 있다. 케이블 타이는 전기, 전자, 자동차, 기계 등 산업 전반에 사용되며, 대부분 전선 또는 부품의 결속용도로 사용되는데, 케이블 타이를 이용한 제품 결속시 마찰로 인한 파티클 현상이 발생한다. 케이블 타이는 일반 공정뿐만 아니라 무결점(Defect Free) 제품을 생산해야 하는 디스플레이 및 반도체 공정 내 제품의 이송 및 적층을 위해 사용되기도 하는 바, 이러한 파티클 발생을 최대한 차단할 필요가 있다.A cable tie, which is often used in display and semiconductor processes, is also a component that induces particles. Cable ties are used throughout industries such as electricity, electronics, automobiles, and machinery, and are mostly used for binding wires or parts. When binding products using cable ties, particles occur due to friction. Cable ties are used not only for general processes, but also for transfer and lamination of products in display and semiconductor processes that need to produce defect-free products, so it is necessary to block the generation of such particles as much as possible.

이상과 같은 본 발명의 클린 케이블 타이에 따르면, 클린 케이블 타이를 초고분자량 폴리에틸렌(UHMWPE; Ultra High Molecular Weight Polyethylene)을 채택하여 제조하였다. 이처럼 재질 변경을 통해 종래 케이블 타이의 주 재료인 폴리아미드66(PA66) 소재로 제조한 것보다 파티클 감소를 감소하였고, 이러한 파티클 감소는 마찰 평가 등을 통해 확인하였다. According to the clean cable tie of the present invention as described above, the clean cable tie was manufactured by adopting Ultra High Molecular Weight Polyethylene (UHMWPE). Through this material change, particle reduction was reduced compared to that made with polyamide 66 (PA66), which is the main material of conventional cable ties, and this particle reduction was confirmed through friction evaluation.
아울러 본 발명은 클린 케이블 타이의 밴드부에 돌기를 형성하되, 이러한 돌기의 직경, 피치, 원주, 높이 등의 수치를 특정하여 성형하였다. 돌기의 수치 값은 반복적인 실험을 통해, 파티클을 최대로 감소시킬 수 있는 값들이라 할 수 있다.In addition, in the present invention, the projections are formed in the band portion of the clean cable tie, and numerical values such as diameter, pitch, circumference, and height of these projections are specified and formed. The numerical values of the protrusions can be said to be values that can reduce particles to the maximum through repeated experiments.
이에 따라 본 발명의 클린 케이블 타이는 와이어나 케이블의 체결, 그리고 체결 후 제품의 이송 및 적층을 위해 움직임이 발생하더라도, 마찰로 인한 분진이나 파티클 발생을 최대한 억제할 수 있는 효과가 있다. 그래서 디스플레이나 반도체 공정에서의 불량율 관리를 사전에 적극적으로 예방이 가능하여 공정 수율의 향상이 기대된다.Accordingly, the clean cable tie of the present invention has the effect of maximally suppressing the generation of dust or particles due to friction even when movement occurs for the transfer and stacking of products after the fastening of the wire or cable and the fastening. Therefore, it is possible to proactively prevent the defect rate management in the display or semiconductor process in advance, and improvement of the process yield is expected.
그리고 본 발명은 체결을 위해 형성된 톱니부 모양을 개선함과 아울러 클린 케이블 타이의 헤드 구조도 개선하였다. 이는 클린 케이블 타이의 소재인 UHMWPE와 협력하여 체결상태가 풀리거나 밴드가 빠지는 현상을 방지하며, 헤드 내에서 스토퍼가 꺾이는 현상도 방지할 수 있다.And the present invention improves the shape of the teeth formed for fastening and also improves the head structure of the clean cable tie. It cooperates with UHMWPE, the material of clean cable ties, to prevent the fastening state from loosening or the band from coming off, and it can also prevent the stopper from being bent in the head.

도 2 및 도 3은 본 발명의 실시 예에 따른 클린 케이블 타이를 나타낸 전후면 사시도이다. 설명의 편의를 위하여 도 2를 전면 사시도, 도 3을 후면 사시도로 설명하나, 그 반대로 정의할 수도 있을 것이다. 도 2 및 도 3에 도시한 바와 같이 클린 케이블 타이(100)는, 일정 길이를 가지는 밴드부(110)와, 밴드부(110)의 일단에서 연장되며 일 방향으로 소정 각도 휘어지는 삽입부(120), 그리고 밴드부(110)의 타단에서 마련되며 삽입부(120) 및 밴드부(110)가 연속해서 끼워지는 헤드(130)를 포함하여 구성된다.2 and 3 are front and rear perspective views showing a clean cable tie according to an embodiment of the present invention. For convenience of explanation, FIG. 2 is a front perspective view and FIG. 3 is a rear perspective view, but the opposite may be defined. 2 and 3, the clean cable tie 100 includes a band portion 110 having a predetermined length, an insertion portion 120 extending from one end of the band portion 110 and bent at a predetermined angle in one direction, and It is provided at the other end of the band part 110 and is configured to include a head 130 into which the insertion part 120 and the band part 110 are continuously fitted.
밴드부(110)는 양 면이 서로 다른 형상으로 형성된다. 한쪽 면(일 면)은 원형 돌기(112)가 형성되고, 다른 면(타 면)은 톱니부(114)가 형성된다. 톱니부(114)의 형상은 아래에서 설명하게 될 스토퍼의 톱니들과 서로 암/수 대응되는 형태로 형성된다. 톱니부(114)와 스토퍼(131)의 톱니와 협력하여 체결대상제품(예를 들면 각종 케이블 등)을 조여 체결하게 된다. 톱니부(114)와 스토퍼(131)의 형상은 아래에서 자세하게 살펴볼 것이다. The band portion 110 is formed in a shape different from each other on both sides. One side (one side) is formed with a circular protrusion 112, the other side (the other side) is formed with a sawtooth portion (114). The shape of the sawtooth portion 114 is formed in male/female correspondence with the teeth of the stopper, which will be described below. In cooperation with the teeth of the toothed portion 114 and the stopper 131, the fastening target product (eg, various cables, etc.) is tightened and fastened. The shape of the toothed part 114 and the stopper 131 will be looked at in detail below.
톱니부(114)의 폭은 밴드부(110)의 폭보다 작다. 톱니부(114)의 상/하측에는 가이드(115)가 형성된다. 가이드(115)와 톱니부(114)는 높이가 동일하거나, 가이드(115)가 더 높게 형성될 수 있다. 가이드(115)가 더 높게 형성될 경우, 가이드(115) 사이에 톱니부(114)가 수용되는 모양일 수 있다.The width of the toothed portion 114 is smaller than the width of the band portion 110 . A guide 115 is formed on the upper / lower side of the toothed portion 114 . The guide 115 and the toothed portion 114 may have the same height, or the guide 115 may be formed higher. When the guide 115 is formed higher, the toothed portion 114 may be accommodated between the guides 115 .
밴드부(110)의 다른 면에 형성된 돌기(112)는 체결대상제품과 직접 접촉하는 부분이다. 본 발명의 클린 케이블 타이(100)로 체결대상 제품을 체결할 경우, 원형 돌기(112)가 형성된 면이 클린 케이블 타이(100)의 내면이 되는 것이다. 그리고 도면에서 돌기(112)는 반구모양으로 형성되나, 이는 일 실시 예에 불과하다. 다른 모양으로 얼마든지 형성할 수 있다. 상기 반구 모양의 돌기(112)는 체결대상제품의 체결상태를 견고하게 증대시키는 기능을 한다. 즉 밴드부(110)의 면에 이러한 돌기(112)가 없이 평면으로 형성될 경우, 체결된 상태의 클린 케이블 타이(100)는 진동이나 외력에 의하여 쉽게 회전하거나 풀릴 수 있기 때문이다. 그러나 본 발명과 같이 반구모양의 돌기(112)를 형성하면 요철모양으로 인해 체결상태를 온전하게 유지할 수 있게 한다. 또 반구 모양의 돌기(112)를 형성하여 체결하면, 체결대상제품과의 접촉면이 적게 되어 파티클을 감소시킬 수 있는 효과도 기대할 수 있다.The projection 112 formed on the other surface of the band 110 is a part in direct contact with the fastening target product. When the fastening target product is fastened with the clean cable tie 100 of the present invention, the surface on which the circular protrusion 112 is formed becomes the inner surface of the clean cable tie 100 . And in the drawing, the projection 112 is formed in a hemispherical shape, but this is only an embodiment. It can be formed into any other shape. The hemispherical protrusion 112 functions to firmly increase the fastening state of the fastening target product. That is, when the surface of the band part 110 is formed in a flat shape without the protrusions 112 , the clean cable tie 100 in the fastened state can be easily rotated or released by vibration or external force. However, if the hemispherical protrusion 112 is formed as in the present invention, the fastening state can be maintained intact due to the concavo-convex shape. In addition, when the hemispherical protrusion 112 is formed and fastened, the contact surface with the fastening target product is reduced, so that the effect of reducing particles can be expected.
특히 이러한 접촉 돌기가 형성된 케이블 타이는 케이블 체결시 장애 발생이나 수율이 떨어지는 문제를 방지할 수 있다. 즉, 종래 일반 케이블 타이로 신호 케이블(signal cable) 및 데이터 케이블(data cable)를 체결할 경우, 체결 강도에 따라 케이블 내의 배열 구조가 틀어지면서 장시간 스트레스로 인해 영상 노이즈 및 감쇄 등이 발생할 수 있어, 궁극적으로 신호 에러를 야기하게 된다. 체결대상제품으로 에어 튜브(Air Tube)을 체결하기도 하는데, 이 역시 체결 강도가 크면 튜브 자체가 협착되어 진공(vacuum) 기능이 떨어져 공정 문제(예를 들면 설비 알람이나 수율 저하 문제 등)가 발생할 수도 있다. In particular, the cable tie in which the contact protrusion is formed can prevent a problem of failure or a decrease in yield when the cable is fastened. That is, when a signal cable and a data cable are fastened with a conventional general cable tie, the arrangement structure in the cable is distorted depending on the fastening strength, and image noise and attenuation may occur due to long-term stress. Ultimately, this will cause signal errors. An air tube is sometimes fastened as a fastening target product. Also, if the tightening strength is high, the tube itself is stenciled and the vacuum function is lowered, which may cause process problems (e.g., equipment alarm or yield reduction problem). have.
그러나, 본 발명의 클린 케이블 타이는 접촉면에 돌기가 형성되어 있어, 그만큼 케이블이나 에어 튜브의 체결시, 케이블 및 에어튜브의 형상을 온전하게 유지시킬 수 있는 것이다. However, since the clean cable tie of the present invention has a protrusion formed on the contact surface, it is possible to maintain the shape of the cable and the air tube intact when the cable or the air tube is fastened.
본 발명은 클린 케이블 타이(100)의 전체 사이즈 대비 원형 돌기(112)의 사이즈 및 간격 등의 수치를 구체적으로 적시하였다. 이는 반복적인 실험을 통해 분진이나 파티클을 최소화할 수 있는 실험 값에 기반하여 제시된 것이다. 본 발명은 이러한 수치와 함께 클린 케이블 타이(100)의 재질 변경을 통해, 원하는 목적을 달성하고 있는 바, 수치 및 재질에 대해서는 아래에서 설명한다.In the present invention, numerical values such as the size and spacing of the circular protrusions 112 compared to the overall size of the clean cable tie 100 were specifically indicated. This is presented based on experimental values that can minimize dust or particles through repeated experiments. The present invention achieves the desired purpose by changing the material of the clean cable tie 100 together with these numerical values, and the numerical values and materials will be described below.
도 1 및 도 2에서 보듯이 삽입부(120)는 일방향으로 구부러져 형성된다. 일정 각도만큼 휘어지게 형성하면, 삽입부(120)를 헤드(130)에 쉽게 끼울 수 있어, 클린 케이블 타이의 체결작업을 더 쉽게 할 수 있다.As shown in FIGS. 1 and 2 , the insertion part 120 is bent in one direction. If it is bent by a certain angle, the insertion part 120 can be easily inserted into the head 130, thereby making it easier to fasten the clean cable tie.
본 발명에 따르면, 클린 케이블 타이(100)의 재질을 변경하여 제조하였다. 일반적인 케이블 타이는 폴리아미드 66(PA66) 소재로 제조되는데, 폴리아미드 66은 Nylon66, Nylon6-6, Nylon6/6으로 많이 불리는 것과 같이 나일론이 주 소재이다. 반면, 본 발명은 클린룸 공정과 같이 파티클에 민감한 공정에 적합한 소재로 초고분자량 폴리에틸렌(UHMWPE)을 사용하였다. UHMWPE는 분자량이 6,000,000g/mol로서, 일반 플라스틱의 분자량인 10,000 ~ 500,000 g/mol 보다 크다. 초고분자량 폴리에틸렌(UHMWPE)으로 케이블 타이를 제조했을 경우, 내마모성이 뛰어나서 마찰시험 평가 등에서 우수한 특징을 제공하는데, 아래의 도 8에서 설명하겠지만, 파티클 감소 효과가 있음을 확인할 수 있다.According to the present invention, it was manufactured by changing the material of the clean cable tie 100 . Common cable ties are made of polyamide 66 (PA66) material, and the main material of polyamide 66 is nylon as it is often called Nylon66, Nylon6-6, and Nylon6/6. On the other hand, in the present invention, ultra-high molecular weight polyethylene (UHMWPE) was used as a material suitable for a process sensitive to particles such as a clean room process. UHMWPE has a molecular weight of 6,000,000 g/mol, which is greater than the molecular weight of general plastics of 10,000 to 500,000 g/mol. When the cable tie is made of ultra-high molecular weight polyethylene (UHMWPE), it has excellent abrasion resistance and provides excellent characteristics in friction test evaluation, etc. As will be described in FIG. 8 below, it can be confirmed that there is an effect of reducing particles.
본 발명에 따른 케이블 타이의 재질 변경과 함께, 클린 케이블 타이의 사이즈도 특정하였다. 도 4는 도 2 및 도 3에 도시한 클린 케이블 타이의 각 부분 치수를 설명하기 위한 도면들로서, (a)는 평면도, (b)는 측면도, (c)는 배면도이다. 도 3을 참조하면 클린 케이블 타이의 각 부분 치수는 다음 [표 1]과 같이 정리할 수 있고, 클린 케이블 타이는 3가지 모델로 제공된다.Along with changing the material of the cable tie according to the present invention, the size of the clean cable tie was also specified. 4 is a view for explaining the dimensions of each part of the clean cable tie shown in FIGS. 2 and 3, (a) is a plan view, (b) is a side view, (c) is a rear view. Referring to FIG. 3 , the dimensions of each part of the clean cable tie can be summarized as in the following [Table 1], and the clean cable tie is provided in three models.

'E'는 헤드 체결공에 마련된 돌기 홈 높이로, 모델별로 0.3± 0.1mm, 0.4± 0.1mm, 0.4± 0.1mm이고, 'F'는 스토퍼의 직경으로 각각 1.2± 0.2mm, 1.4± 0.2mm, 2.2± 0.2mm로 제조된다.As shown in [Table 1], the total length (L) for each model is 100mm, 150mm, 210mm, and the width (W) is 3.0±0.4, 4.0±0.4, and 5.2±0.4mm, respectively, for each model. And 'A' is the protrusion size (diameter), and models 1, 2, and 3 are manufactured in 1.13±0.2, 1.34±0.2mm, and 2.0±0.2mm, respectively. 'B' is the protrusion spacing (pitch) and is 1.5± 0.2mm, 1.8± 0.2mm, 2.6± 0.2mm for each model, and 'C' is the protrusion height, 0.2± 0.1mm, 0.3± 0.1mm, 0.3± 0.1, respectively. mm and 'D' are manufactured to have Φ1.8±0.2, Φ1.8±0.2, and Φ2.5±0.2, respectively, as the circumference of the protrusion. As a result of specifically designing the size, pitch, height and circumference of the protrusions formed in the band, it can be confirmed that there is a particle reduction effect compared to the existing cable tie.

도 5에 도시된 본 발명의 클린 케이블 타이(100)의 헤드(130)는 스토퍼(131)를 포함한다. 스토퍼(131)는 일단은 고정되고 타단은 자유단으로 이루어지는 몸체(132)와, 몸체(132)의 자유단측에 형성된 톱니들(133)을 포함한다. 각각의 톱니는 대략 사다리꼴 형상으로 아래쪽 폭이 위쪽보다 더 길게 형성된다. 그리고 스토퍼 톱니(133)와 밴드부(110)의 톱니가 엇갈려서 결합할 수 있도록 밴드부 톱니는 스토퍼 톱니와 대응되는 형상으로 형성된다. 또 몸체(132)의 측면에 꺽임 방지턱(134)이 돌출 형성된다. 꺽임 방지턱(134)은 밴드부(110)가 들어가는 헤드(130)의 입구측 방향에 마련된다. The head 130 of the clean cable tie 100 of the present invention shown in FIG. 5 includes a stopper 131 . The stopper 131 includes a body 132 having one end fixed and the other end having a free end, and teeth 133 formed on the free end side of the body 132 . Each tooth has a substantially trapezoidal shape, and the lower width is longer than the upper one. And so that the stopper teeth 133 and the teeth of the band part 110 are alternately coupled to each other, the band teeth are formed in a shape corresponding to the stopper teeth. In addition, a bending protrusion 134 is formed on the side of the body 132 to protrude. The bending protrusion 134 is provided in the direction of the entrance side of the head 130 into which the band part 110 enters.
본 발명의 스토퍼(131)는 헤드(130)의 입구(즉 체결시 밴드부가 들어가는 부분) 및 출구(밴드부가 나오는 부분) 단면과 일정 간격 이격된다. 도면과 같이 입구 단면과 꺽임 방지턱(134) 사이의 제1 거리(P1)과 출구 단면과 몸체(132) 단면 사이의 제2 거리(P2)이다. The stopper 131 of the present invention is spaced apart from the inlet (ie, the portion where the band enters when fastening) and the outlet (the portion where the band comes out) of the head 130 by a predetermined interval. As shown in the figure, the first distance P1 between the inlet section and the bending bump 134 and the second distance P2 between the outlet section and the body 132 end face are shown.
이처럼 클린 케이블 타이를 초고분자량 폴리에틸렌(UHMWPE)으로 제조하면서 스토퍼(131)의 톱니들 형상을 개선하게 되면(g2 부분), 체결 후 헤드(130)에서 밴드부(110)가 빠지는 현상을 개선할 수 있다. 그리고 꺽임 방지턱(134)을 형성하고, 제1 거리(P1) 및 제2 거리(P2)의 2곳의 완충거리가 확보되도록 설계함으로써, 클린 케이블 타이(100)를 당겼을 때 스토퍼(131)의 연결부위(g1 부분)의 꺽임 현상을 방지할 수 있다.As such, if the shape of the teeth of the stopper 131 is improved while manufacturing the clean cable tie with ultra-high molecular weight polyethylene (UHMWPE) (part g2), the phenomenon that the band part 110 is removed from the head 130 after fastening can be improved. . And the stopper 131 when the clean cable tie 100 is pulled by forming the bending bump 134 and designing to secure the buffer distances of two places of the first distance P1 and the second distance P2. It is possible to prevent bending of the connecting part (g1 part).
반면 도 6의 종래 케이블 타이의 헤드 구조와 비교하면, 톱니 모양과 스토퍼의 길이에서 차이가 있음을 알 수 있다. 특히 종래 케이블 타이는 앞서 언급한 바와 같이 대부분이 나일론 소재인 PA66 재질로 제조된다. 그래서 재질 특성상 톱니들이 쉽게 마모되기 때문에, 약간의 충격으로도 헤드에서 밴드부가 빠져 체결 상태가 풀릴 수 있다(g2' 부분). 또 수분에 취약하기 때문에 끊어지는 문제도 있다. 아울러 종래 케이블 타이는 밴드부를 당겼을 때 당김에 따라 스토퍼의 연결부위(g1' 부분)가 꺽어질 수 있다. On the other hand, compared with the head structure of the conventional cable tie of FIG. 6, it can be seen that there is a difference in the sawtooth shape and the length of the stopper. In particular, as mentioned above, the conventional cable tie is made of PA66 material, which is mostly nylon material. Therefore, since the teeth are easily worn due to the nature of the material, even a slight impact can cause the band to come off the head and loosen the fastening (g2' part). Also, there is a problem of breaking because it is vulnerable to moisture. In addition, in the conventional cable tie, the connection part (g1' part) of the stopper may be bent as the band part is pulled.
도 7은 도 5의 헤드(130) 영역 확대도이다. 도면과 같이 헤드(130) 내에는 밴드부(110)가 관통되도록 절개된 영역인 체결공(140)이 형성된다. 그리고 체결공(140)의 상측에 톱니들이 형성된 스토퍼(131)가 형성되고, 좌우측면에는 밴드부(110)의 가이드(115)가 끼워져 이동되는 가이드 홈(115a)이 넓게 형성되며, 하면에는 돌기(112)를 안내하는 돌기 홈(112a)이 형성된다. 그리고 체결공(140)을 통과한 밴드부(110)를 충분히 잡아당긴 상태가 되면 스토퍼(131) 톱니와 밴드부(110) 톱니가 서로 결합하여 체결대상제품을 체결한다.7 is an enlarged view of the head 130 region of FIG. 5 . As shown in the drawing, a fastening hole 140 is formed in the head 130, which is an area cut through the band 110 to pass therethrough. And a stopper 131 having teeth is formed on the upper side of the fastening hole 140, and a guide groove 115a into which the guide 115 of the band part 110 is inserted and moved is formed on the left and right side surfaces, and a protrusion ( A protrusion groove 112a for guiding the 112 is formed. And when the band portion 110 that has passed through the fastening hole 140 is sufficiently pulled, the teeth of the stopper 131 and the teeth of the band 110 are coupled to each other to fasten the product to be fastened.
다음은 종래 케이블 타이와 본 발명의 클린 케이블 타이의 테스트 결과에 대해 살펴본다. 시험 조건 및 시험 방법은 다음과 같다. 표 2는 시험 조건이다. The following will look at the test results of the conventional cable tie and the clean cable tie of the present invention. The test conditions and test methods are as follows. Table 2 shows the test conditions.

시험 방법은 테스트 케이블과 케이블 타이의 상호 간의 마찰(10만회, 20만회)로 인한 비교 시험방법이고, 케이블 재질별로 그랜드로 정렬한 상태에서 케이블 타이를 각각 설치하여 시험하였다. The test method is a comparative test method due to the friction between the test cable and the cable tie (100,000 times, 200,000 times), and each cable tie was installed and tested in the state of arranging the glands for each cable material.
테스트 결과는, 폴리아미드66(PA66) 재질로 제조한 일반 케이블 타이 대비 본 발명의 UHMWPE로 제조한 클린 케이블 타이가 약 30~40% 정도 저감되었고, 최대 90%정도까지 파티클 발생을 줄일 수 있었다. 또 파티클 비산 저감효과도 있음을 확인하였다. 특히 돌기 사이즈를 상기한 표 1과 같이 성형했을 경우 파티클 발생이 최대로 저감되었음을 확인할 수 있었다.As a result of the test, the clean cable tie made of the UHMWPE of the present invention was reduced by about 30-40% compared to the general cable tie made of polyamide 66 (PA66), and the generation of particles was reduced by up to 90%. In addition, it was confirmed that there is an effect of reducing particle scattering. In particular, when the projection size was molded as shown in Table 1, it was confirmed that the generation of particles was reduced to the maximum.
즉 도 8은 본 발명의 클린 케이블 타이와 종래 제품과의 마찰 시험 평가 결과를 보인 도면으로, 케이블 재질별(PUR, PVC, TPE) 모두 종래 PA66으로 제조된 케이블 타이보다 본 발명의 UHMWPE로 제조된 클린 케이블 타이가 파티클 발생을 현저하게 감소시키고 있음을 알 수 있다. 이처럼 본 발명의 클린 케이블 타이는 파티클 저감 효과를 기대할 수 있어, 디스플레이 및 반도체 공정에서의 생산 수율 중요성에 적합하다고 할 것이다.That is, FIG. 8 is a view showing the friction test evaluation results between the clean cable tie of the present invention and the conventional product. For each cable material (PUR, PVC, TPE), it is manufactured with UHMWPE of the present invention rather than cable ties made of conventional PA66. It can be seen that clean cable ties significantly reduced particle generation. As such, the clean cable tie of the present invention can be expected to reduce particles, so it will be said that it is suitable for the importance of production yield in display and semiconductor processes.
이와 같이 본 발명의 클린 케이블 타이는, 종래 나일론 소재의 플라스틱 케이블 타이와 비교하면, 클린룸 내 공정에서의 파티클을 저감하고, 공정 수율을 개선할 수 있는 것이다.As such, the clean cable tie of the present invention can reduce particles in the process in the clean room and improve the process yield, compared with the conventional plastic cable tie made of nylon material.
디스플레이 생산 장비나 반도체 제조설비는 물론 일반 작업 현장에서 사용되는 각종 와이어나 케이블을 조여 체결하기 위한 다양한 분야에 적용할 수 있다. It can be applied to various fields for fastening and fastening various wires or cables used in general work sites as well as display production equipment and semiconductor manufacturing facilities.
