Description

탄소섬유 강화 열가소성 보강판넬 제조장치{Carbon Fiber Reinforced Thermoplastic Reinforcement Panel Manufacturing Equipment}Carbon Fiber Reinforced Thermoplastic Reinforcement Panel Manufacturing Equipment

본 발명은 탄소섬유 강화 열가소성 보강판넬 제조장치에 관한 것이다.The present invention relates to an apparatus for manufacturing a carbon fiber reinforced thermoplastic reinforcing panel.

탄소섬유 강화 열가소성 보강판넬을 만드는 다양한 방법 중에, 자동섬유적층기(Automated Fiber Placement Machine)로, 몰드 위에 열가소성 탄소섬유테이프를 절단하여 놓고, 절단된 열가소성 탄소섬유테이프를 가열 및 가압하여 탄소섬유 강화 열가소성 보강판넬을 만드는 방법이 있다.Among the various methods for making carbon fiber reinforced thermoplastic reinforcing panels, an Automated Fiber Placement Machine cuts and places a thermoplastic carbon fiber tape on a mold, and heats and presses the cut thermoplastic carbon fiber tape to create a carbon fiber reinforced thermoplastic. There is a way to make a reinforcing panel.

도 1에 도시된 바와 같이, 종래 탄소섬유 강화 열가소성 보강판넬 제조장치는, 몰드판(21)과 자동섬유적층기로 구성된다. 자동섬유적층기는 헤드부(13)가 컷팅부(13a), 레이저부(13b), 가압부(13c)로 구성된다. 1, the conventional carbon fiber reinforced thermoplastic reinforcing panel manufacturing apparatus is composed of a mold plate 21 and an automatic fiber laminator. In the automatic fiber laminator, the head part 13 is composed of a cutting part 13a, a laser part 13b, and a pressing part 13c.

필름(22)은 실링재(ST)에 의해 몰드판(21)의 상면에 부착된다.The film 22 is attached to the upper surface of the mold plate 21 by the sealing material ST.

컷팅부(13a)는 필름(22) 위에 열가소성 탄소섬유테이프(T)를 컷팅하여 올려놓는다. 레이저부(13b)는 열가소성 탄소섬유테이프(T)에 레이저 빔(E1)을 조사하여 열가소성 탄소섬유테이프(T)를 가열한다. 열가소성 탄소섬유테이프(T) 내 열가소성 수지가 녹는다. 가열된 열가소성 탄소섬유테이프를 가압한다. 이를 반복하여, 몰드판(21) 위에 설정된 형상과 두께를 가진 탄소섬유 강화 열가소성 보강판넬을 만들어낸다. The cutting part 13a cuts and puts the thermoplastic carbon fiber tape T on the film 22 . The laser unit 13b heats the thermoplastic carbon fiber tape T by irradiating the laser beam E1 to the thermoplastic carbon fiber tape T. The thermoplastic resin in the thermoplastic carbon fiber tape (T) is melted. Press the heated thermoplastic carbon fiber tape. By repeating this, a carbon fiber reinforced thermoplastic reinforcing panel having a shape and thickness set on the mold plate 21 is produced.

한편, 튜브(24)는 실링재(ST)를 한쪽을 통과하여, 필름(22)의 하면과 몰드판(21)의 상면 사이 공간 내 공기를 흡입한다. 이럴 경우, 튜브(24)가 필름(22)의 한쪽 방향으로만 공기를 흡입하므로, 진공흡착력이 필름(22)에 고르게 작용하지 못하게 된다. 이로 인해, 도 2에 도시된 바와 같이 필름(22)에 주름이 생기게 된다. 따라서, 필름(22) 위에서 열가소성 탄소섬유테이프를 적층시켜 만드는 탄소섬유 강화 열가소성 보강판넬의 품질이 현저하게 떨어진다.On the other hand, the tube 24 passes through one side of the sealing material ST, and sucks air in the space between the lower surface of the film 22 and the upper surface of the mold plate 21 . In this case, since the tube 24 sucks air in only one direction of the film 22 , the vacuum adsorption force does not work evenly on the film 22 . Due to this, wrinkles are generated in the film 22 as shown in FIG. Accordingly, the quality of the carbon fiber-reinforced thermoplastic reinforcing panel made by laminating the thermoplastic carbon fiber tape on the film 22 is remarkably deteriorated.

본 발명은, 몰드판에 균일한 간격으로 형성된 복수 개의 진공흡착공을 통해, 몰드의 상면에 놓인 필름에 균일한 진공흡착력을 제공한다. 이로 인해, 필름 전체에 균일하게 진공흡착력이 작용되어, 필름에 주름이 생기지 않는다. 여기에 더하여, 복수 개의 진공흡착공 마다 개폐밸브를 설치하여, 진공흡착공 각각의 진공흡착력을 미세하게 조절하여, 필름에 미세한 주름까지 생기지 않게 한다. 여기에 더하여, 복수 개의 진공흡착공의 상단에 그 주위를 감싸는 면상발열체를 설치하고, 복수 개의 진공흡착공 마다 개폐밸브를 설치하여, 필름에 열과 진공흡착력을 동시에 주어 필름에 미세한 주름까지 생기지 않게 한다. 따라서, 상술한 몰드를 사용하면, 필름 위에서 열가소성 탄소섬유테이프를 적층하여 고품질의 탄소섬유 강화 열가소성 보강판넬을 만들어낼 수 있다.The present invention provides a uniform vacuum adsorption force to the film placed on the upper surface of the mold through a plurality of vacuum adsorption holes formed at uniform intervals on the mold plate. For this reason, the vacuum adsorption force is uniformly applied to the entire film, and wrinkles do not occur in the film.

[몰드][Mold]

몰드(100)는 몰드판(110), 필름(120), 튜브(140)로 구성된다.The mold 100 includes a mold plate 110 , a film 120 , and a tube 140 .

<몰드판><Mold plate>

몰드판(110)은 세라믹이나 금속 재질로 만들어져 판 형상으로 형성된다. 몰드판(110)에는 복수 개의 진공흡착공(130)이 형성된다. 진공흡착공(130)은 몰드판(110)의 상면에서 하면 방향으로 관통되어 형성된다. 진공흡착공(130)은 도 4 및 도 5에 도시된 바와 같이 균일한 간격으로 배치되고 몰드판(110)의 전체 영역에 고르게 배치된다. The mold plate 110 is made of a ceramic or metal material and is formed in a plate shape. A plurality of vacuum suction holes 130 are formed in the mold plate 110 . The vacuum suction hole 130 is formed to penetrate in the direction from the upper surface of the mold plate 110 to the lower surface. The vacuum suction holes 130 are arranged at uniform intervals as shown in FIGS. 4 and 5 and are evenly arranged over the entire area of the mold plate 110 .

<필름><Film>

필름(120)은 몰드판(110)의 상면을 덮는다. 필름(120)은 열가소성 수지가 녹는 온도 350℃ 이상에서 견딜 수 있는, 폴리이미드, 테프론 등으로 만들어진다. 필름(120)은 실링재(ST)에 의해 몰드판(110)의 상면에 부착된다. 실링재(ST)는 필름(120)의 테두리를 따라 위치된다. The film 120 covers the upper surface of the mold plate 110 . The film 120 is made of polyimide, Teflon, etc., which can withstand a temperature of 350° C. or higher at which the thermoplastic resin melts. The film 120 is attached to the upper surface of the mold plate 110 by the sealing material ST. The sealing material ST is positioned along the edge of the film 120 .

<튜브><tube>

튜브(140)는 일측이 복수 개의 진공흡착공(130) 각각에 연결되며, 타측이 진공펌프(미도시)와 연결된다. 진공펌프(미도시)는 튜브(140)를 통해 각각의 진공흡착공(130)에 진공흡착력을 제공한다. 튜브(140)를 통해 진공흡착공(130)에 진공이 작용하면, 필름(120)이 몰드판(110)에 밀착된다. 복수 개의 진공흡착공(130)이 몰드판(110)의 전체 영역에 고르게 균일한 간격으로 배치됨으로써, 진공펌프(미도시)의 진공흡착력이 각각의 진공흡착공(130)들을 통해 몰드판(110)의 상면에 배치된 필름(120)의 전체 영역에 균일하게 작용될 수 있다. 이로 인해, 필름(120)에 주름이 생기지 않는다.One side of the tube 140 is connected to each of the plurality of vacuum suction holes 130, and the other side is connected to a vacuum pump (not shown). A vacuum pump (not shown) provides a vacuum suction force to each vacuum suction hole 130 through the tube 140 . When vacuum is applied to the vacuum suction hole 130 through the tube 140 , the film 120 is in close contact with the mold plate 110 . Since the plurality of vacuum suction holes 130 are evenly and evenly spaced over the entire area of the mold plate 110 , the vacuum suction power of the vacuum pump (not shown) is applied to the mold plate 110 through the respective vacuum suction holes 130 . ) may be uniformly applied to the entire area of the film 120 disposed on the upper surface. For this reason, wrinkles do not occur in the film 120 .

[제1변형예에 따른 몰드][Mold according to the first modification]

도 6에 도시된 바와 같이, 제1변형예에 따른 몰드(100a)는, 복수 개의 진공흡착공(130) 마다 개폐밸브(150)가 더 설치된다. 이로 인해, 진공흡착공(130) 각각의 진공흡착력이 미세하게 조절되어, 필름(120)에 미세한 주름까지 생기지 않게 만든다. 개폐밸브(150)는 몰드판(110)의 하면에 설치되어, 일단이 진공흡착공(130)에 연통되고, 타단이 튜브(140)에 연결된다.As shown in FIG. 6 , in the mold 100a according to the first modification, an on/off valve 150 is further installed in each of the plurality of vacuum suction holes 130 . For this reason, the vacuum adsorption force of each of the vacuum adsorption holes 130 is finely adjusted, so that even fine wrinkles do not occur in the film 120 . The on/off valve 150 is installed on the lower surface of the mold plate 110 , one end communicates with the vacuum suction hole 130 , and the other end is connected to the tube 140 .

개폐밸브(150)의 개폐도에 의해, 진공흡착공(130)의 진공흡착력이 조절된다. 이를 위해, 개폐밸브(150)는 밸브 하우징과, 밸브 하우징 내에 회전가능하게 결합된 회전볼과 회전볼을 회전시키는 구동부로 구성된다. 회전볼의 회전각도에 따라 개폐밸브(150)의 개폐도는 달라질 수 있다. 이 밖에 개폐밸브(150)는 공지된 기술을 사용하여 다양하게 구성될 수 있다. 개폐밸브(150)의 개폐도는 작업자가 수동으로 조절될 수 있다. 한편, 개폐밸브(150)의 개폐도를 자동으로 조절할 수도 있다. 이 경우, 필름(120)을 상측에서 찍는 카메라와, 상기 카메라에서 보내온 영상을 보면서 필름(120)의 주름이 없어질 때까지, 개폐밸브(150)의 개폐도를 조절하는 제어부가 더 포함된다.

도 8에 도시된 바와 같이, 레이저부(222)는 복수 개로 단위 레이저(222a)로 구성된다. 복수 개의 단위 레이저(222a)는 일렬로 배치되어 절단된 열가소성 탄소섬유테이프(T)에, 레이저 빔(E1)을 조사한다. 그러면, 열가소성 탄소섬유테이프(T)가 가열되어, 열가소성 탄소섬유테이프(T) 내 열가소성 수지가 녹는다. 본 실시예에서는 6.35mm 폭의 열가소성 탄소섬유테이프(T)가 최대 16개 공급 가능하므로, 레이저부는 16개의 단위 레이저(222a)가 일렬로 배치된다.As shown in FIG. 8 , the laser unit 222 includes a plurality of unit lasers 222a. A plurality of unit lasers 222a are arranged in a line and irradiate a laser beam E1 to the cut thermoplastic carbon fiber tape T. Then, the thermoplastic carbon fiber tape (T) is heated, and the thermoplastic resin in the thermoplastic carbon fiber tape (T) is melted. In this embodiment, since a maximum of 16 thermoplastic carbon fiber tapes (T) having a width of 6.35 mm can be supplied, 16 unit lasers 222a of the laser unit are arranged in a line.

한 개의 단위 레이저(222a)는 한 개의 열가소성 탄소섬유테이프(T)에 레이저 빔(E1)을 조사한다. 한 개의 단위 레이저(222a)가 방출하는 레이저 빔(E1)의 폭은 한 개의 열가소성 탄소섬유테이프(T)의 폭에 대응하도록 형성된다. 따라서, 한 개의 단위 레이저(222a)는 한 개의 열가소성 탄소섬유테이프(T)를 담당하여 가열하게 된다. One unit laser 222a irradiates a laser beam E1 on one thermoplastic carbon fiber tape T.

Accordingly, one unit laser (222a) is heated by taking charge of one thermoplastic carbon fiber tape (T).

복수 개의 단위 레이저(222a)는 전체가 일률적으로 작동되는 것이 아니고 각각 개별적으로 제어된다. 따라서, 레이저 빔(E1)을 조사하는 단위 레이저(222a)의 개수를 조절하여 조사되는 레이저 빔(E1)의 폭을 조절할 수 있다. 도 5에 도시된 바와 같이, 공급되는 열가소성 탄소섬유테이프(T)의 전체 폭이 복수 개의 단위 레이저(222a)의 전체 폭보다 작은 경우, 열가소성 탄소섬유테이프(T)의 폭 위치에 대응하는 단위 레이저(222a)만을 작동시켜 레이저 빔(E1)을 조사할 수 있다. The plurality of unit lasers 222a are not all operated uniformly, but are individually controlled. Accordingly, the width of the irradiated laser beam E1 may be adjusted by adjusting the number of unit lasers 222a irradiating the laser beam E1. 5, when the total width of the supplied thermoplastic carbon fiber tape (T) is smaller than the total width of the plurality of unit lasers (222a), the unit laser corresponding to the width position of the thermoplastic carbon fiber tape (T) Only the 222a can be operated to irradiate the laser beam E1.
