Description

필름 제조 형틀, 그 제조 방법 및 이에 의해 제조된 필름Film manufacturing mold, manufacturing method thereof, and film manufactured thereby

The present invention relates to a film manufacturing mold, a method for manufacturing the same, and a film manufactured by the same, which allow the simple and easy manufacturing of a pattern film essential for manufacturing the security film and efficiently utilize it in manufacturing the security film.
개인정보 보호 방법의 일 예로 사용자가 정보기기의 디스플레이 부분을 정면에서 바라볼 경우에는 아무런 제한이 없도록 하는 반면에, 그 정보기기의 디스플레이 부분을 정면에서 벗어나 옆면에서 비스듬히 바라볼 경우에는 그 정보를 차단하는 방식인 보안 필름을 들 수 있다.As an example of a method for protecting personal information, there is no restriction when the user looks at the display part of the information device from the front, while blocking the information when the user looks at the display part of the information device from the front and obliquely from the side A security film can be mentioned.
이러한 보안 필름은 일반적으로 금형에 의한 전사 방법으로 제조될 수 있다. 구체적으로 필름 제조 형틀의 돌기를 수지상에 전사하여 홈을 만들고 광불투과성 재료를 홈에 충진하여 보안 필름을 제조하게 된다.Such a security film may be generally manufactured by a transfer method using a mold. Specifically, the projections of the film manufacturing mold are transferred onto the resin to form a groove, and a light-opaque material is filled in the groove to manufacture a security film.
이때 필름 제조 형틀의 제조 과정에서 돌기는 정밀한 절삭 또는 연삭, 식각 과정을 통해 형성할 수 있다. 이러한 돌기 제조 과정은 매우 정밀하고 복잡하며 많은 시간이 필요하다.In this case, in the manufacturing process of the film manufacturing frame, the projections may be formed through precise cutting, grinding, or etching processes. This protrusion manufacturing process is very precise, complex, and requires a lot of time.
일반적으로 필름 제조 형틀의 돌기는 다이아몬드터닝머신이나 정밀 미세 바이트로 절삭하거나, 레이저로 녹이거나, 포토리소그라피를 이용하여 표면을 부식시켜 여러 공정을 거쳐 제작하거나, 3D 프린터를 이용하여 적층하여 제작할 수 있다. 이러한 돌기를 갖는 필름 제조 형틀은 미세 패턴(홈)을 갖는 프리즘시트, 보안필름, 재귀반사 필름 등 다양한 제품을 제작할 수 있다.In general, the protrusion of the film manufacturing mold can be manufactured through various processes by cutting it with a diamond turning machine or a precision fine bite, melting it with a laser, or corroding the surface using photolithography, or by stacking it using a 3D printer. . The film manufacturing mold having such protrusions can manufacture various products such as a prism sheet having a fine pattern (grooves), a security film, and a retroreflective film.
이러한 형틀은 고가의 장비로 여러 단계를 거쳐 제작되어 고비용이며, 돌기와 돌기 사이의 거리 폭에 대한 돌기의 높이 비인 세장비(Aspect ratio = AR)를 크게 제작하는 고세장비 제작이 어렵고, 다양한 패턴의 형상을 제조하기가 어렵다. These molds are expensive and expensive because they are manufactured through several steps, and it is difficult to manufacture high-profile equipment that produces a large aspect ratio (AR), which is the ratio of the height of the projection to the width of the distance between the projections. It is difficult to manufacture.
고세장비 형틀은 절삭이나 연삭 방식으로 제작하는 경우, 진동과 버(Burr)가 발생하는 등 표면조도와 치수 정밀도가 떨어진다. 이러한 고세장비 형틀의 형상을 필름에 전사하기 위해 광경화 수지를 침투시킨 후 경화시키면, 경화된 재료가 형틀에서 제대로 분리되지 않는 이형성의 문제가 있다. When a high-definition mold is manufactured by cutting or grinding, the surface roughness and dimensional accuracy are poor, such as vibration and burrs. In order to transfer the shape of such a high-definition mold to a film, if the photo-curing resin is penetrated and then cured, there is a problem of releasability in which the cured material is not properly separated from the mold.
형틀 제조시 절삭이나 연삭, 화학적 처리가 용이한 소재를 사용하게 되는 경우에는, 상대적으로 강도와 경도가 약한 소재를 사용하기 때문에 형틀의 내구성이 높지 않아 제작 후 형틀의 형상이 변형되는 문제가 있다.When a material that is easy to cut, grind, or chemically process is used for manufacturing the mold, the durability of the mold is not high because the material with relatively weak strength and hardness is used, so there is a problem that the shape of the mold is deformed after production.
다이싱쏘와 같은 미세한 폭을 연삭하는 장치는 다수의 연삭 날을 갖추어도 돌기와 제작된 필름의 미세 간격이 같은 간격으로 구성되지 못해, 비슷한 형상이 반복되는 돌기를 제작하기에 여러 번 같은 작업을 반복하여 시간이 많이 소요된다.A device for grinding a fine width, such as a dicing saw, does not have the same spacing between the projections and the produced film even when equipped with a large number of grinding blades. It takes a lot of time.
또한, 이와 유사한 도광판 등을 제작하기 위한 단일 박판 적층 방식(1020010005193)은 돌기 말단 형태만을 조절할 수가 있어서, 고세장비를 갖는 보안필름을 제작할 수 없으며, 금형 부속들을 매우 작게 절단 후 조립하여 금형을 완성하는 방식(1020200058707)은 매우 정밀한 부속을 다루는 기술이 요구되어, 고세장비를 갖고, 표면이 매끄러우며, 간격을 일정하게 조절하기가 어렵다.In addition, the single thin plate lamination method (1020010005193) for manufacturing a light guide plate similar to this can only control the shape of the protrusion end, so it is not possible to manufacture a security film with high-definition equipment, and the mold parts are cut very small and assembled to complete the mold. The method (1020200058707) requires a technique for handling very precise parts, has high-definition equipment, has a smooth surface, and it is difficult to adjust the spacing uniformly.
이처럼, 종래의 필름 제조 형틀을 제조하는 방법은 그 제조설비가 비싸 제품의 원가를 상승시키고, 최종제품의 품질을 보장하기 어려우며, 제조과정이 복잡한 문제가 있다.As such, the conventional method of manufacturing a film manufacturing mold has problems in that the manufacturing equipment is expensive, increasing the cost of the product, it is difficult to guarantee the quality of the final product, and the manufacturing process is complicated.
본 개시의 기술적 사상이 해결하려는 과제는 보안 필름을 제조하기 위한 필름 제조 형틀을 간단하고 손쉽게 제작하여 효율적으로 활용할 수 있도록 하는 필름 제조 형틀 및 그 제조 방법을 제공하는 데 있다.An object of the technical spirit of the present disclosure is to provide a film manufacturing mold and a method for manufacturing the same, which can be efficiently and efficiently manufactured by simply and easily manufacturing a film manufacturing mold for manufacturing a security film.

도 1은 본 개시의 예시적 실시 예에 따른 필름 제조 형틀의 사시도이다.1 is a perspective view of a film manufacturing form according to an exemplary embodiment of the present disclosure;
도 1을 참조하면, 본 개시의 예시적 실시 예에 따른 미세 형상이 형성된 필름(10, 도 2b 참조)을 제조하기 위한 필름 제조 형틀(100)은 금속이나 비금속인 세라믹, 합성수지 등으로 제작된 판 형태의 재료로 이루어진 사이판(110) 및 돌기판(120)으로 형성될 수 있다. 구체적으로, 필름 제조 형틀(100)은 복수의 사이판(110) 및 복수의 사이판(110)과 교대로 적층 방향(A)으로 적층되는 복수의 돌기판(120)을 포함할 수 있다. 복수의 돌기판(120)은 적층 방향(A)에 수직인 방향(B)으로 사이판(110)보다 소정의 높이만큼 돌출되도록 배치될 수 있다.Referring to FIG. 1 , a film manufacturing frame 100 for manufacturing a film 10 having a fine shape according to an exemplary embodiment of the present disclosure (see FIG. 2B ) is a plate made of metal or non-metallic ceramic, synthetic resin, etc. It may be formed of a sipe 110 and a protrusion plate 120 made of a material of the form. Specifically, the film manufacturing frame 100 may include a plurality of saipans 110 and a plurality of protrusions 120 alternately stacked with the plurality of saipans 110 in the lamination direction (A). The plurality of protrusion boards 120 may be disposed to protrude by a predetermined height from the side plate 110 in a direction B perpendicular to the stacking direction A.
사이판(110)은 판 형상으로 이루어질 수 있다. 사이판(110)은 돌기판(120)과 교번적으로 배치되어 돌기판(120)과 돌기판(120) 사이를 이격시킬 수 있다. 복수의 사이판(110)들은 후술하는 돌기부(140)의 간격이 일정하도록 두께가 동일하게 형성될 수 있다. 사이판(110)은 후술하는 필름의 광투과면을 제조할 수 있다. Saipan 110 may be formed in a plate shape. Sai plate 110 may be alternately disposed with the protrusion plate 120 to space the protrusion plate 120 and the protrusion plate 120 from each other. The plurality of sipes 110 may be formed to have the same thickness so that the intervals between the protrusions 140 to be described later are constant. Saipan 110 may manufacture a light-transmitting surface of a film to be described later.
돌기판(120)은 판 형상으로 이루어질 수 있다. 돌기판(120)은 사이판(110)과 사이판(110) 사이로 돌출되도록 배치될 수 있다. 돌기판(120)은 후술하는 필름의 광불투과면을 형성하는 홈(11)을 제조할 수 있다.The protrusion plate 120 may be formed in a plate shape. The protrusion plate 120 may be disposed to protrude between the sai plate 110 and the sai plate 110 . The protrusion plate 120 may manufacture a groove 11 forming a light-transmitting surface of a film to be described later.
본 개시의 일 실시 예에 따른 필름 제조 형틀(100)에서, 돌기판(120)은 돌출되어 나오는 부분을 형성하고, 사이판(110)은 오목하게 들어간 부분을 형성할 수 있다.In the film manufacturing formwork 100 according to an embodiment of the present disclosure, the protrusion plate 120 may form a protruding portion, and the siding plate 110 may form a concave portion.
돌기판(120)은 필름(10)에 홈(11)과 같은 형상으로 이루어진 미세패턴을 형성하기 위한 것으로, 돌기판(120)의 두께(w2)는 사이판(110)의 두께(w1) 보다 얇게 형성될 수 있다.The protrusion plate 120 is for forming a micropattern having the same shape as the groove 11 in the film 10 , and the thickness w2 of the protrusion plate 120 is thinner than the thickness w1 of the siding plate 110 . can be formed.
돌기판(120)은 그와 바로 인접하여 있는 다른 돌기판(120)에 대하여 사이판(110)에 의해 일정한 거리(w1)만큼 이격되어 있다. 구체적으로, 돌기판(120)들은 사이판(110)의 두께(w1)만큼 이격되도록 배치될 수 있다. The protrusion plate 120 is spaced apart from the other protrusion plate 120 immediately adjacent thereto by a predetermined distance w1 by the siding plate 110 . Specifically, the protrusion plates 120 may be disposed to be spaced apart by the thickness w1 of the siding plate 110 .
사이판(110)의 두께(w1)가 돌기판(120)의 두께(w2)의 2배인 경우, 이러한 필름 제조 형틀(100)에 의해 제조된 보안 필름(10)의 광투과부의 면적은 66%로 이루어질 수 있다. 한편, 사이판(110)의 두께(w1)가 돌기판(120) 두께(w2)의 3배인 경우, 필름 제조 형틀(100)에 의해 제조된 보안 필름(10)의 광투과부의 면적은 75%로 이루어질 수 있다. 즉, 사이판(110)의 두께(w1)가 클수록 보안 필름의 광투과도가 좋아 선명한 화면을 볼 수 있으나, 보안 필름의 보안 기능이 저하될 수 있다. When the thickness w1 of the sipe 110 is twice the thickness w2 of the protrusion board 120, the area of the light transmitting portion of the security film 10 manufactured by the film manufacturing mold 100 is 66%. can be done On the other hand, when the thickness w1 of the sipe 110 is three times the thickness w2 of the protrusion board 120 , the area of the light transmitting portion of the security film 10 manufactured by the film manufacturing mold 100 is 75%. can be done That is, the greater the thickness w1 of the sipe 110 is, the better the light transmittance of the security film is, so that a clear screen can be viewed, but the security function of the security film may be deteriorated.
보안필름의 경우 광불투과부의 두께가 50㎛ 보다 작아야 미세 형상이 눈에 잘보이지 않는다. 이에 따라 돌기판(120)의 두께를 50㎛ 이하로 형성할 수 있다. 이러한 필름 제조 형틀(100)에 의해 제조된 필름은 광불투과부가 눈에 보이지 않아 광투과부 사이로 나오는 빛을 통해 정보전달을 원활히 수행할 수 있다. In the case of a security film, the thickness of the light-transmitting part must be less than 50㎛ so that the fine shape is not easily visible. Accordingly, the thickness of the protrusion plate 120 may be formed to be 50 μm or less. In the film manufactured by the film manufacturing frame 100 , the light non-transmissive part is not visible to the naked eye, so that information can be transmitted smoothly through the light emitted between the light transmissive parts.
사이판(110)의 두께(w1)와 돌기판(120)의 두께(w2)는 필름 제조 형틀(100)에 의해 형성되는 최종 제품에 따라 달라질 수 있다. 일 예로, 최종 제품이 방충망이나 커텐, 블라인더 등인 경우 광불투과부가 눈에 보여도 상관 없기 때문에 사이판(110)의 두께와 돌기판(120)의 두께는 50㎛ 이상으로 형성될 수 있다.The thickness w1 of the siding plate 110 and the thickness w2 of the protrusion plate 120 may vary depending on the final product formed by the film manufacturing frame 100 . For example, when the final product is an insect screen, curtain, blinder, etc., the thickness of the siding plate 110 and the thickness of the protrusion plate 120 may be formed to be 50 μm or more because the light-transmitting part may be visible.
사이판(110)과 돌기판(120)은 서로 같은 소재로 이루어질 수 있다. 이 경우 소재의 성질이 동일하여 제조 과정에서 물리적인 절단이나 연삭 등이 용이할 수 있다. 또한 후술하는 적층부(130)의 상부면인 사이판 윗면과 돌기판 윗면의 필름 접촉 가능 면을 부드럽게 연결한 가상의 면인 기준면(131, 도 4b 참조)을 가공하기 위해 도금이나 코팅하는 경우 기준면(131) 전체 표면에 걸쳐 균일하게 수행될 수 있는 이점이 있다. Saipan 110 and protrusion board 120 may be made of the same material. In this case, since the properties of the material are the same, physical cutting or grinding may be easy during the manufacturing process. In addition, when plating or coating to process the reference surface (131, see Fig. 4b), which is a virtual surface that smoothly connects the upper surface of the saipan, which is the upper surface of the lamination unit 130, and the film-contactable surface of the upper surface of the protrusion, which will be described later, the reference surface 131 ) has the advantage that it can be performed uniformly over the entire surface.
한편, 사이판(110)과 돌기판(120)은 서로 다른 소재로 이루어질 수 있다. 이 경우, 돌기판(120)과 소재의 성질이 다른 사이판(110)을 화학처리 또는 열처리하여 사이판(110)의 일부를 제거하여 돌기뷰(140)를 형성할 수 있다.Meanwhile, the sipe 110 and the protrusion plate 120 may be made of different materials. In this case, the protrusion view 140 may be formed by chemically treating or heat-treating the saipan 110 having different material properties from the protrusion plate 120 to remove a portion of the saipan 110 .
사이판(110)의 일부가 제거되면 남은 돌기판(120)은 사이판(110)보다 소정의 높이만큼 돌출되도록 형성될 수 있다. 사이판(110)과 돌기판(120)이 서로 다른 소재로 이루어진 경우 사이판(110)의 부분적인 화학처리 또는 열처리를 통해 돌기부(140)를 용이하게 형성할 수 있다.When a part of the sai plate 110 is removed, the remaining protrusion plate 120 may be formed to protrude by a predetermined height than the sai plate 110 . When the saipan 110 and the protrusion plate 120 are made of different materials, the protrusion 140 can be easily formed through a partial chemical treatment or heat treatment of the saipan 110 .
구체적으로, 사이판(110)으로 구리판을 구비하고, 돌기판(120)으로 플라스틱 소재의 연마재를 포함한 판을 구비할 수 있다. 사이판(110)과 돌기판(120)이 교대로 적층된 적층부(130)의 기준면(131)을 화학 처리하여 사이판(110)인 구리의 일부를 제거하여 돌기부(140)를 형성할 수 있다. 돌기부(140)는 필름 제조 시 미세 연마날로 작용하여 필름(10)에 미세 홈을 형성할 수 있다. Specifically, a copper plate may be provided as the sipe 110 , and a plate including an abrasive made of a plastic material may be provided as the protrusion plate 120 . The protrusion 140 may be formed by chemically treating the reference surface 131 of the lamination unit 130 on which the saipan 110 and the protrusion plate 120 are alternately stacked to remove a portion of copper that is the saipan 110 . The protrusion 140 may function as a fine grinding blade during film manufacturing to form fine grooves in the film 10 .
또한 사이판(110)을 알루미늄 소재로 구성하고, 돌기판(120)을 스테인리스스틸 소재로 구성하는 경우, 화학처리는 물론 열을 가하여 알루미늄 소재로 이루어진 사이판(110)만을 제거하여 돌기부(140)를 용이하게 형성할 수 있다.In addition, when the saipan 110 is made of an aluminum material and the protrusion plate 120 is made of a stainless steel material, the protrusion 140 is facilitated by removing only the saipan 110 made of an aluminum material by applying heat as well as chemical treatment. can be formed
필름 제조 형틀(100)은 적층부(130)와 돌기부(140)를 포함할 수 있다.The film manufacturing frame 100 may include a lamination part 130 and a protrusion part 140 .
적층부(130)는 교대로 적층된 복수의 사이판(110)과 복수의 돌기판(120)으로 이루어질 수 있다. 적층부(130)는 바닥면을 형성하고, 가로 및 세로 길이를 가지는 직사각형의 형상으로 형성될 수 있다. The stacking unit 130 may include a plurality of side plates 110 and a plurality of protrusion boards 120 that are alternately stacked. The stacking unit 130 may form a bottom surface and have a rectangular shape having horizontal and vertical lengths.
적층부(130)는 돌기가 돌출되는 기준면(131)을 형성할 수 있다. 기준면(131, 도 4b 참조)은 필름(10)에 홈(11)과 같은 미세 형상을 형성하기 위해 필름(10)이 접촉되는 면을 제공한다. 기준면(131)은 평면으로 형성될 수 있다.The stacking unit 130 may form a reference surface 131 on which the protrusion protrudes. The reference surface 131 (refer to FIG. 4B ) provides a surface on which the film 10 is in contact to form a micro-shape such as a groove 11 in the film 10 . The reference plane 131 may be formed as a flat surface.
돌기부(140)는 적층부(130)로부터 돌출 형성될 수 있다. 구체적으로, 돌기부(140)는 적층부(130)의 기준면(131) 위쪽으로 돌출 형성되고, 단면의 모양은 일렬로 복수의 막대기형으로 형성된 평면 스탬프형이 될 수 있다. The protrusion 140 may be formed to protrude from the stacking unit 130 . Specifically, the protrusion 140 is formed to protrude above the reference surface 131 of the stacking unit 130 , and the shape of the cross-section may be a flat stamp type formed in a plurality of bar shapes in a line.
다만, 돌기부(140)의 형상은 이에 한정하지 않고 돌출된 부분이 곡선으로 연결된 라운드 형상, 기울기를 갖는 경사진 형상, 격자로 형성된 바둑판 형상으로 형성될 수 있다. 이에 따라, 필름 제조 형틀(100)은 스탬프형으로 기준면(131)이 평면인 평면 스탬프형, 돌출된 부분을 연결한 모양이 곡률을 갖는 곡면 스탬프형, 평면이 경사진 경사 스탬프형으로 형성될 수 있고, 스탬프형의 적층체를 잘라 중간에 격자를 형성시켜 다시 적층 한 바둑판 형상처럼 격자 스탬프형으로 형성될 수 있다.However, the shape of the protrusion 140 is not limited thereto, and may be formed in a round shape in which the protruding portions are connected by a curve, an inclined shape having a slope, or a checkerboard shape formed by a grid. Accordingly, the film production mold 100 is a stamp type, and the reference surface 131 is a flat flat stamp type, a curved stamp type with a curvature in the shape connecting the protruding parts, and an inclined stamp type with an inclined plane. In addition, it can be formed in a lattice stamp type like a checkerboard shape in which a stamp-type laminate is cut and a grid is formed in the middle.
필름 제조 형틀은 스탬프형으로 평면 스탬프형, 경사 스탬프형, 곡면 스탬프형 중 하나일 수 있다.The film manufacturing mold may be one of a flat stamp type, an inclined stamp type, and a curved stamp type as a stamp type.
필름 제조 형틀(100)은 판 형상으로 이루어진 복수의 사이판(110)과 복수의 돌기판(120)을 교번적으로 적층하여 돌출 형성된 돌기부(140)와 오목하게 들어간 부분을 갖도록 형성될 수 있다. 필름 제조 형틀(100)은 그 구조 및 형상이 간단하여 제작이 용이하다. 필름 제조 형틀의 제조 방법은 도 3에서 자세하게 후술한다. The film manufacturing frame 100 may be formed to have a protrusion 140 and a concave portion formed by alternately stacking a plurality of siding plates 110 and a plurality of protrusion plates 120 formed in a plate shape to protrude. The film manufacturing mold 100 is easy to manufacture because its structure and shape are simple. A method of manufacturing the film manufacturing mold will be described later in detail with reference to FIG. 3 .
보안필름에서 돌기부(140)의 높이가 인접한 돌기판(120) 사이의 간격보다 클수록 제작된 필름의 시야각 제한 효과가 크다. 이에 따라, 보안 필름의 보안 기능을 향상시키기 위해 돌기부(140)의 높이(h)는 사이판(110)의 두께(w1)의 길이보다 크게 형성될 수 있다. 바람직하게는, 돌기부(140)의 높이(h)는 사이판(110) 두께(w1) 길이의 2배로 형성되면 투명부가 공기와 같은 굴절률일 경우 30°정도의 시야각 제한 효과가 있다.In the security film, the greater the height of the protrusions 140 is greater than the distance between the adjacent protrusion plates 120, the greater the effect of limiting the viewing angle of the manufactured film. Accordingly, in order to improve the security function of the security film, the height h of the protrusion 140 may be formed to be greater than the length w1 of the thickness w1 of the siding plate 110 . Preferably, when the height h of the protrusion 140 is formed to be twice the length of the thickness w1 of the sipe 110, when the transparent portion has the same refractive index as air, there is an effect of limiting the viewing angle of about 30°.
종래의 필름 제조 형틀은 미세 절삭이나 연삭, 식각 방법으로 돌기부를 형성하였기 때문에 돌기부의 높이를 사이판 두께의 2배 이상으로 제작하는 경우 정밀도가 떨어지고, 돌기부의 각도를 일정하게 유지하기 어려운 문제가 있었다. Since the conventional film manufacturing mold forms the protrusion by fine cutting, grinding, or etching method, when the height of the protrusion is manufactured to be more than twice the thickness of the sipe, the precision is lowered, and it is difficult to keep the angle of the protrusion constant.
본 개시의 일 실시 예에 따른 필름 제조 형틀은 돌기판(120)의 높이 조절을 통해서 돌기부(140)를 형성할 수 있어 정밀도를 높일 수 있다. 또한 돌기부(140)는 돌기판(120)의 위치 이동만으로 형성할 수 있어 돌기부(140)의 높이 방향에 대해 일정한 각도를 이루도록 형성될 수 있다. In the film manufacturing form according to an embodiment of the present disclosure, the protrusion 140 may be formed by adjusting the height of the protrusion plate 120 , thereby increasing precision. In addition, the protrusion 140 may be formed only by moving the position of the protrusion plate 120 , and thus may be formed to form a predetermined angle with respect to the height direction of the protrusion 140 .
필름 제조 형틀(100)은 판 형상의 사이판(110)과 돌기판(120)의 교번적 배치를 통해 제조되어 최초 판의 형상을 손상시키거나 찌그러짐 없이 제조되므로 품질을 동일하게 유지할 수 있는 이점이 있다.Since the film manufacturing frame 100 is manufactured through the alternating arrangement of the plate-shaped sipe 110 and the protrusion plate 120, the shape of the first plate is not damaged or distorted, so there is an advantage that the quality can be maintained the same. .
대부분의 판재 혹은 필름은 두께가 거의 일정하고 표면이 매끄럽게 처리되어 있다. 판형태의 재료를 원하는 두께를 선별하여 모양에 맞게 적층하게 되면 돌출되어 나온 돌기와 오목하게 들어간 부분을 쉽게 제작할 수 있다.Most boards or films have almost constant thickness and a smooth surface. By selecting the desired thickness of the plate-shaped material and stacking it according to the shape, the protruding protrusion and the concave part can be easily manufactured.
필름 제조 형틀(100)은 복수의 사이판(110)과 복수의 돌기판(120)을 적층된 상태로 고정시키는 고정대(150)를 더 포함할 수 있다. 고정대(150)에 대해서는 도 4 및 도 5에서 자세하게 설명한다.The film manufacturing frame 100 may further include a holder 150 for fixing the plurality of siding plates 110 and the plurality of protrusion plates 120 in a stacked state. The fixing table 150 will be described in detail with reference to FIGS. 4 and 5 .

도 2a 및 도 2b를 참조하면, 필름 제조 형틀(100)은 적층부(130)와, 적층부(130)의 일측면에 돌출 형성된 돌기부(140)로 이루어질 수 있다. 필름 제조 형틀(100) 위에 합성수지 필름(10)을 배치하여 적층부(130)의 외주면에 돌출 형성된 돌기부(140)에 의해 합성수지 필름(10)에 골구조인 홈(11)을 형성할 수 있다.Referring to FIGS. 2A and 2B , the film manufacturing frame 100 may include a lamination part 130 and a protrusion 140 protruding from one side of the lamination part 130 . By disposing the synthetic resin film 10 on the film manufacturing mold 100 and protruding from the outer peripheral surface of the lamination part 130, a groove 11 having a trough structure can be formed in the synthetic resin film 10 by the protrusion 140.
필름 제조 형틀(100)은 돌기부(140)의 길이 방향을 따라 왕복 운동하여 미세 홈(11)을 갖는 필름(10)을 제조할 수 있다. 이러한 필름 제조 형틀(200)을 스탬프형 필름 제조 형틀이라고 한다.The film manufacturing frame 100 may reciprocate along the longitudinal direction of the protrusion 140 to manufacture the film 10 having the microgrooves 11 . Such a film manufacturing mold 200 is called a stamp-type film manufacturing mold.
필름 제조 형틀(100)에 의해 필름(10)에 홈(11)을 형성하게 되면, 홈(11)은 광불투과부를 형성하게 되고, 그에 인접한 부분은 광투과부를 형성할 수 있다. 일 예로, 홈(11)에 유색잉크를 충전하여 광불투과부를 형성하고, 광불투과부와 광투과부의 외주면에 투명한 필름을 코팅하는 방식으로 보안필름을 제조할 수 있다.When the groove 11 is formed in the film 10 by the film manufacturing frame 100 , the groove 11 forms a light-transmitting portion, and a portion adjacent thereto can form a light-transmitting portion. For example, a security film may be manufactured by filling the groove 11 with colored ink to form a light-transmitting part, and coating a transparent film on the light-opaque part and the outer peripheral surface of the light-transmitting part.

In addition, in the manufacturing method of the film manufacturing mold according to an exemplary embodiment of the present invention, after the laminating step (S310), one end surface of the laminate consisting of the alternatingly laminated saipan 110 and the protruding plate 120 is processed It may further include the step of
적층체를 고정대로 고정하는 단계(S320)는 사이판(110)들 사이에 배치된 돌기판(120)을 적층체의 일단면 방향으로 이동시키고 고정대로 고정하는 방법으로 구성될 수 있다. The step of fixing the stacked body to the fixing rod (S320) may be configured by moving the protruding plate 120 disposed between the siding plates 110 in the direction of one end of the stacked body and fixing it with the fixing rod.
한편, 적층체를 고정대로 고정하는 단계(S320)는 적층체에서 사이판(110)의일부분을 화학 처리 또는 열 처리하여 제거하기 전에 적층체를 고정대로 고정하는 방법으로 구성될 수 있으며, 적층체를 관통하지 않고 외부에서 고정할 수도 있으며, 적층체 내면 또는 외면을 접착제로 처리하여 최종형태에서는 고정대가 제거된 상태의 필름 제조 형틀을 제조할 수 있다.On the other hand, the step of fixing the laminate to the fixing rod (S320) may consist of a method of fixing the laminate to the fixing rod before removing a part of the saipan 110 from the laminate by chemical treatment or heat treatment, It may be fixed from the outside without penetrating, and by treating the inner surface or outer surface of the laminate with an adhesive, a film production frame in a state in which the holder is removed in the final form may be manufactured.
또 다른 한편, 돌기부(140)는 돌기부(140)의 높이만큼 사이판(110)보다 크게 제조된 돌기판(120)을 구비하여 돌기판(120)과 사이판(110)을 교대로 적층하는 방법으로 형성될 수 있다.On the other hand, the protrusion 140 is formed by alternately stacking the protrusion plate 120 and the saipan 110 with the protrusion plate 120 manufactured to be larger than the saipan 110 by the height of the protrusion 140 . can be
본 개시의 예시적 실시 예에 따른 필름 제조 형틀(100) 제조 방법은 사이판(110)과 돌기판(120)을 적층시키는 방법으로 돌기부(140)를 형성하기 때문에 종래의 방법보다 필름 제조 형틀(100)을 간단하고 용이하게 제조할 수 있다. 이 경우, 용이하게 다양한 형상을 갖는 돌기부(140)를 포함하는 필름 제조 형틀을 제조할 수 있다. 이에 따라 필름(10)에 다양한 미세 형상을 형성할 수 있어 활용도가 높다.Since the method for manufacturing the film manufacturing template 100 according to an exemplary embodiment of the present disclosure forms the protrusions 140 by laminating the sipe 110 and the protrusion plate 120, the film manufacturing template 100 is higher than the conventional method. ) can be manufactured simply and easily. In this case, it is possible to easily manufacture a film manufacturing mold including the protrusions 140 having various shapes. Accordingly, various micro-shapes can be formed on the film 10 , so the utilization is high.
도 4a 내지 도 4c는 본 개시의 예시적 실시 예에 따른 필름 제조 형틀의 제조 방법을 도시한 도면이다.4A to 4C are diagrams illustrating a method of manufacturing a film manufacturing frame according to an exemplary embodiment of the present disclosure.
도 4a를 참조하면, 본 개시의 예시적 실시 예에 따른 필름 제조 형틀(100)의 제조 방법은 판 형상의 사이판(110) 및 돌기판(120)을 준비하는 단계를 포함할 수 있다. Referring to FIG. 4A , the method of manufacturing a film manufacturing frame 100 according to an exemplary embodiment of the present disclosure may include preparing a plate-shaped siding plate 110 and a protrusion plate 120 .
사이판(110)과 돌기판(120) 두께는 서로 상이하지만, 동일한 면적을 갖는 형상으로 구성될 수 있다. 사이판(110)의 두께(w1) 길이는 돌기판(120)의 두께(w2) 길이 보다 더 크게 형성될 수 있다.Although the thickness of the siding plate 110 and the protrusion plate 120 are different from each other, they may be configured in a shape having the same area. The length of the thickness w1 of the side plate 110 may be greater than the length of the thickness w2 of the protrusion plate 120 .
사이판(110)은 복수의 제1 고정홀(111)과 제1 지지홀(113)을 포함할 수 있다. 제1 고정홀(111)과 제1 지지홀(113)은 동일한 높이에 형성될 수 있다. Saipan 110 may include a plurality of first fixing holes 111 and first support holes 113 . The first fixing hole 111 and the first support hole 113 may be formed at the same height.
돌기판(120)에는 제2 고정홀(121)과 제2 지지홀(123)이 형성될 수 있다. 제2 고정홀(121)은 제1 고정홀(111)보다 낮은 높이에 형성될 수 있고, 제2 지지홀(123)은 제1 지지홀(113)과 동일한 높이에 형성될 수 있다. 구체적으로, 제2 고정홀(121)은 제1 고정홀(111)과의 높이 차이가 돌기부(140)의 높이만큼 차이 나는 위치에 형성될 수 있다.A second fixing hole 121 and a second support hole 123 may be formed in the protrusion plate 120 . The second fixing hole 121 may be formed at a lower height than the first fixing hole 111 , and the second supporting hole 123 may be formed at the same height as the first supporting hole 113 . Specifically, the second fixing hole 121 may be formed at a position where the height difference from the first fixing hole 111 is different by the height of the protrusion 140 .
준비된 판 형상의 사이판(110)과 돌기판(120)은 적층 방향으로 교대로 적층한다.The prepared plate-shaped siding plate 110 and protrusion plate 120 are alternately stacked in the stacking direction.
도 4b를 참조하면, 사이판(110)과 돌기판(120)이 적층되어 적층체(101)를 형성될 수 있다. 적층체(101)는 임시고정대(155)에 의해 임시적으로 고정될 수 있다. 임시고정대(155)는 사이판(110)의 제1 지지홀(113)과 돌기판(120)의 제2 지지홀(123)을 통과하도록 배치되어 사이판(110)과 돌기판(120)을 적층된 상태로 고정할 수 있다.Referring to FIG. 4B , a siding plate 110 and a protrusion plate 120 may be stacked to form a laminate 101 . The stacked body 101 may be temporarily fixed by the temporary fixing unit 155 . The temporary fixture 155 is disposed to pass through the first support hole 113 of the saipan 110 and the second support hole 123 of the protrusion plate 120 to stack the sai plate 110 and the protrusion plate 120 . state can be fixed.
기준면(131)은 필름(10)과 맞닿는 면으로 돌기부(140)의 윗면과, 돌기부(140)가 형성된 적층부(130)의 사이판 윗면으로 구성될 수 있다. 적층체(101)에서 돌기부(140)의 윗면과 사이판의 윗면을 연결한 면을 기준면(131)이라고 한다. 스탬프 형 필름 제조 형틀은 돌기부(140)의 윗면을 연결한 가상의 면과 사이판의 윗면을 연결한 가상의 면이 일치할 수 있어서 기준면이 1개일 수 있다. The reference surface 131 is a surface in contact with the film 10 , and may include an upper surface of the protrusion 140 and an upper surface of the sipe of the laminate 130 on which the protrusion 140 is formed. In the laminate 101 , a surface connecting the upper surface of the protrusion 140 and the upper surface of the sipe is referred to as a reference surface 131 . In the stamp-type film manufacturing mold, the imaginary surface connecting the upper surface of the protrusion 140 and the imaginary surface connecting the upper surface of the saipan may coincide with each other, so that there may be one reference surface.
사이판(110)과 돌기판(120)을 적층한 이후에, 적층체(101)에서 돌기부(140)가 형성되는 기준면(131)을 가공할 수 있다. 도 4b에 도시된 가상의 기준면(131a)을 참조하면, 기준면(131)은 평면으로 형성될 수 있고, 돌기부(140)의 방향에 대해 수직하게 형성될 수 있다.After laminating the sipe 110 and the protrusion plate 120 , the reference surface 131 on which the protrusion 140 is formed in the laminate 101 may be machined. Referring to the virtual reference surface 131a illustrated in FIG. 4B , the reference surface 131 may be formed in a flat surface and may be formed perpendicular to the direction of the protrusion 140 .
한편, 적층체(101)의 기준면(131)이 소정의 거칠기를 갖도록 가공할 수 있다. 구체적으로, 돌기부(140)가 톱날과 같이 작용하도록 기준면(131)을 톱니 형상으로 가공할 수 있다.Meanwhile, the reference surface 131 of the laminate 101 may be processed to have a predetermined roughness. Specifically, the reference surface 131 may be machined into a sawtooth shape so that the protrusion 140 acts like a saw blade.
기준면(131)은 도금 또는 코팅할 수 있다. 구체적으로 돌기부(140)의 강도를 높이고 필름 제조 형틀(100) 표면의 이형성을 향상시키기 위해 크롬(Cr) 등과 같은 금속으로 도금할 수 있고, DLC코팅 등과 같이 코팅할 수 있다. The reference surface 131 may be plated or coated. Specifically, in order to increase the strength of the protrusion 140 and improve the releasability of the surface of the film manufacturing mold 100, it may be plated with a metal such as chromium (Cr), and may be coated with DLC coating.
기준면(131)의 가공을 통해 사이판(110)과 돌기판(120)의 접촉면 사이의 틈을 채울 수 있다. 필름 제조 형틀(100) 상에 필름을 전사하여 홈(11)이 형성된 필름(10)을 제조하는 경우 액체 수지가 사이판(110)과 돌기판(120)의 접촉면 사이의 틈으로 들어가는 것을 방지할 수 있다.Through the processing of the reference surface 131 , a gap between the contact surface of the sipe 110 and the protrusion plate 120 may be filled. When the film 10 having the groove 11 is formed by transferring the film onto the film manufacturing frame 100 , it is possible to prevent the liquid resin from entering the gap between the contact surface of the sipe 110 and the protrusion plate 120 . there is.
기준면(131)은 평면으로 형성된 것으로 설명하였으나, 이에 한정하지 않고 기준면(131)은 곡면, 경사면 등 다양한 형상을 형성하도록 가공될 수 있다.Although it has been described that the reference surface 131 is formed as a flat surface, the reference surface 131 is not limited thereto and may be processed to form various shapes such as a curved surface or an inclined surface.
도 4c를 참조하면, 기준면(131)을 가공한 이후 사이판(110)들 사이에 배치된 돌기판(120)을 적층 방향에 수직인 방향으로 돌출되도록 배치하여 돌기부(140)를 형성할 수 있다. Referring to FIG. 4C , after processing the reference plane 131 , the protrusion 140 may be formed by disposing the protrusion plate 120 disposed between the siding plates 110 to protrude in a direction perpendicular to the stacking direction.
돌기판(120)을 사이판(110)들로부터 돌출되도록 배치할 수 있다.The protrusion plate 120 may be disposed to protrude from the side plates 110 .
일 예로, 돌기판(120)을 사이판 두께(w1) 길이의 2배 이상으로 돌출되도록 적층방향에 수직인 방향으로 위치 이동시킬 수 있다. 이에 따라 돌기부(140)는 높이(h)가 사이판 두께(w1) 길이의 2배 이상이 되도록 형성될 수 있다. 본 개시의 일 실시 예에 따른 필름 제조 형틀(100)은 돌기판(120)을 돌출 배치하여 적층하는 것으로 돌기부(140)의 높이(h)를 용이하게 조절할 수 있다.For example, the protrusion plate 120 may be moved in a direction perpendicular to the stacking direction so as to protrude more than twice the length of the thickness w1 of the siding plate. Accordingly, the protrusion 140 may be formed such that the height h is at least twice the length of the thickness w1 of the siding. In the film manufacturing mold 100 according to an embodiment of the present disclosure, the height h of the protrusion 140 can be easily adjusted by protrudingly disposing and stacking the protrusion plates 120 .
돌기부(140)의 높이(h)가 돌기들 사이의 간격인 사이판의 두께(w1) 보다 클수록 필름 제조 형틀(100)에 의해 제조된 필름의 시야각 제한 효과가 크다. 따라서, 보안 필름으로 사용되는 필름(10)을 제조하기 위해 필름 제조 형틀(100)의 돌기부(140)는 사이판(110) 두께(w1)의 2배 높이를 갖도록 형성될 수 있다.As the height (h) of the protrusions 140 is greater than the thickness w1 of the siding, which is the interval between the protrusions, the viewing angle limiting effect of the film manufactured by the film manufacturing frame 100 is greater. Accordingly, in order to manufacture the film 10 used as the security film, the protrusion 140 of the film manufacturing frame 100 may be formed to have twice the height of the thickness w1 of the sipe 110 .
기존의 필름 제조 형틀은 미세 절삭 또는 연삭, 식각 방법으로 돌기부의 높이를 조절하기 때문에 높은 정밀도가 요구되고, 돌기부의 높이가 돌기 사이 간격의 2배가 되도록 형틀을 형성하는 경우 제작 과정에서 돌기들의 각도를 일정하게 유지하기 어렵고, 표면 가공이 어려운 문제가 있었다. Existing film manufacturing molds require high precision because the height of the projections is controlled by fine cutting, grinding, or etching. It was difficult to keep it constant, and there was a problem in that surface processing was difficult.
한편, 본 개시의 일 실시 예에 따른 필름 제조 형틀(100)은 돌기판(120)의 적층 위치를 조절하여 고정하는 것으로 돌기부(140)의 높이를 조절할 수 있어 고도의 정밀도가 요구되지 않아 제조 과정이 간단하고, 돌기들의 각도를 일정하게 유지할 수 있다. 또한 본 개시의 일 실시 예에 따른 필름 제조 형틀(100)은 표면 가공 후에 돌기판(120)의 적층 위치를 조절할 수 있어 표면 가공이 유리한 이점이 있다. On the other hand, in the film manufacturing mold 100 according to an embodiment of the present disclosure, the height of the protrusion 140 can be adjusted by adjusting and fixing the lamination position of the protrusion plate 120 , so a high degree of precision is not required during the manufacturing process. This simple, it is possible to keep the angle of the projections constant. In addition, since the film manufacturing mold 100 according to an embodiment of the present disclosure can adjust the lamination position of the protrusion board 120 after surface processing, there is an advantage in surface processing.
돌기판(120)이 사이판(110)으로부터 돌출되도록 배치하기 위해, 임시적으로 고정한 임시고정대(155)를 제1 지지홀(113) 및 제2 지지홀(123)에서 빼고, 고정대(150)를 제1 고정홀(111) 및 제2 고정홀(121)을 통과하도록 배치시켜 돌기부(140)를 형성할 수 있다. In order to arrange the protrusion plate 120 to protrude from the sipe 110, the temporarily fixed temporary holder 155 is removed from the first support hole 113 and the second support hole 123, and the holder 150 is removed. The protrusion 140 may be formed by disposing it to pass through the first fixing hole 111 and the second fixing hole 121 .
돌기부(140)는 제1 고정홀(111)과 제2 고정홀(121)의 높이 차이만큼의 돌기 높이를 갖도록 형성될 수 있다. The protrusion 140 may be formed to have a protrusion height equal to a height difference between the first fixing hole 111 and the second fixing hole 121 .
다른 실시 예로 사이판의 고정 홀과 같은 위치에 돌기판의 고정 홀을 만들되 돌기판의 고정 홀은 돌기 높이 만큼 크거나 길게 형성시켜, 사이판과 돌기판을 고정대로 꿰고 느슨한 상태에서 자석이나 중력을 이용하여 아래쪽으로 움직이게 한 다음 고정대의 양쪽에서 죄어 고정시켜 적층체를 만들고, 기준면을 가공한 다음 적층체의 고정대를 느슨하게 하고, 적층체를 거꾸로 놓거나 자석을 이용하여 돌기판을 이동시키고 고정대로 고정하여 미세 형틀을 제작할 수도 있다.In another embodiment, make the fixing hole of the protrusion in the same position as the fixing hole of the saipan, but make the fixing hole of the protrusion as large or long as the height of the protrusion. Make a laminate by moving it downward and then clamping it on both sides of the holder to make a laminate, machine the reference plane, and then loosen the holder of the laminate. Turn the laminate upside down or use a magnet to move the protruding plate and fix it with the fixing rod to make a fine mold. can also be produced.
본 개시의 다른 예시적 실시 예에 따른 필름 제조 형틀(100)의 제조 방법은 도 4b의 기준면을 형성하는 단계를 제외하고, 돌기판(120)을 사이판(110)보다 돌기부(140)의 높이만큼 차이나게 기준면(131) 방향으로 더 돌출되게 적층하는 방법으로 구성될 수 있다. 임시 고정 단계를 제외하고, 제1 고정홀(111)과 제2 고정홀(121)에 고정대(150)를 배치하여 필름 제조 형틀(100)을 제조할 수 있다.In the manufacturing method of the film manufacturing formwork 100 according to another exemplary embodiment of the present disclosure, except for the step of forming the reference plane of FIG. 4B , the protrusion plate 120 is formed by the height of the protrusion 140 rather than the sipe 110 . Differently, it may be configured in a method of stacking to protrude further in the direction of the reference plane 131 . Except for the temporary fixing step, the film manufacturing frame 100 may be manufactured by arranging the holder 150 in the first fixing hole 111 and the second fixing hole 121 .
