Description

유로가 있는 연료전지 분리판의 두께와 유로 깊이 측정장치{Thickness and channel depth measuring apparatus of fuel cell bipolar plate}Thickness and channel depth measuring apparatus of fuel cell bipolar plate

본 발명은, 예를 들어 유로와 구멍이 형성된 연료전지 분리판과 같은 판의 두께와 유로 깊이를 측정하는 장치에 관한 것으로, 특히 휨 발생이 이루어진 성형된 연료전지 분리판을 정밀하고 신속하게 측정할 수 있는 유로가 있는 연료전지 분리판의 두께와 유로 깊이 측정장치에 관한 것이다.The present invention relates to an apparatus for measuring the thickness and channel depth of a plate, such as a fuel cell separator plate having a flow path and a hole, for example, and particularly to accurately and quickly measure a molded fuel cell separator plate in which warpage has occurred. The present invention relates to a thickness and flow path depth measuring apparatus for a fuel cell separator having a flow path.

일반적으로 연료전지 분리판의 두께를 측정하는 방식은 크게 3가지 방식으로 이루어지는바, X선이나 광선을 이용하여 측정하는 광학적 측정방법과, 진공 흡착방식을 이용하여 베이스 지그와 측정 대상물을 밀착시킨 후에 두께를 측정하는 방법 및, 측정 대상물의 휨 문제를 해결하기 위한 도막 측정방식으로 구분되어 있다.In general, the thickness of the fuel cell separator is measured in three ways. The optical measuring method using X-rays or light rays and the vacuum suction method are used to closely adhere the base jig and the measuring object. It is divided into the method of measuring thickness, and the coating-film measuring method for solving the bending problem of a measurement object.

여기서 광학적 측정방법은 비파괴 방식이면서 측정 대상물인 판의 두께와 유연성에 상관없이 측정할 수 있는 장점이 있지만 휨이 형성된 판의 두께를 정확하게 측정할 수 없는 단점을 지니고 있었다. 즉 측정 대상물인 판의 휨으로 인하여 이 판과 판이 안착되는 베이스 지그 사이에 빈공간이 발생하게 되고, 이 빈공간 만큼 측정오차가 발생하기 때문이다.Here, the optical measuring method has the advantage of being able to measure the thickness of non-destructive and irrespective of the thickness and flexibility of the object to be measured, but has the disadvantage of not being able to accurately measure the thickness of the warped plate. That is, due to the bending of the plate to be measured, an empty space is generated between the plate and the base jig on which the plate is seated, and a measurement error occurs as much as this empty space.

실제로 성형된 연료전지 분리판을 프레스 성형작업 후 약간의 휨이 발생하기 때문에 정밀한 측정을 위해서는 상기와 같은 광학적 측정방법을 사용할 수가 없었다.Actually, the molded fuel cell separator may not be able to use the above optical measurement method for precise measurement because some warpage occurs after the press molding operation.

한편, 진공흡착 방식은 측정 대상물인 판의 휨 문제를 해결할 수 있는 장점이 있지만, 측정하고자 하는 측정 대상물인 판이 아주 얇은 박판이거나 유연한 판이면 가능하나, 연료전지 분리판은 이 판을 안착하는 지그의 표면에 맞게 휘어서 밀착되는 정도의 유연성을 갖추고 있지 않으면서 유로와 구멍 등이 있기 때문에 진공흡착 방식으로는 두께와 유로측정이 불가능하였다.On the other hand, the vacuum adsorption method has the advantage of solving the problem of bending of the plate to be measured, but it is possible if the plate to be measured is a very thin thin plate or flexible plate, but the fuel cell separation plate of the jig seating this plate Since there were flow paths and holes without having the flexibility to bend and fit to the surface, it was impossible to measure the thickness and flow path by the vacuum adsorption method.

그리고, 연료전지 분리판의 두께를 측정하는 현재 사용하고 있는 도막 측정방식은 휨 문제를 해결하면서 정밀하게 측정할 수 있는 장점이 있지만, 연료전지 분리판을 도막형태로 만들어야 측정이 가능하기 때문에 연료전지 분리판을 절단하는 파괴측정 방식이며, 측정하기 위해서는 많은 시간과 작업단계를 거쳐야 한다. 즉 연료전지 분리판을 절단하는 단계 → 절단된 도막을 측정하는 단계 → 측정값 기록단계 → 통계 및 확인단계 등 여러 단계를 거쳐야 하는 문제점이 있었다.In addition, the coating film measuring method currently used to measure the thickness of the fuel cell separating plate has the advantage of being able to measure precisely while solving the warpage problem. It is a fracture measuring method that cuts separators, and it takes a lot of time and work steps to measure them. That is, there was a problem in that the fuel cell separator has to go through several steps such as cutting the cut film → measuring the cut film → recording the measured value → statistics and checking.

이에 본 발명은 종래 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 유로와 구멍들이 형성된 연료전지 분리판의 두께와 유로 깊이를 측정할 때 휨이 발생한 성형된 연료전지 분리판을 비파괴 방식을 이용하여 정밀하고 신속하게 측정하는 연료전지 분리판의 두께와 유로 깊이 측정장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the problems as described above, by using a non-destructive method for forming a fuel cell separator plate in which warpage occurs when measuring the thickness and channel depth of the fuel cell separator plate having the flow path and holes formed therein. It is an object of the present invention to provide a thickness and flow path depth measuring apparatus for measuring fuel cells in a precise and rapid manner.

상기와 같은 목적을 달성하기 위한 본 발명은 유로가 있는 연료전지 분리판의 두께와 유로 깊이를 측정유닛을 이용하여 측정하는 장치에 있어서, 상기 연료전지 분리판이 안착되는 하판지그와, 이 하판지그에 안착되는 연료전지 분리판의 측정부위를 밀착시키는 중공의 원통형 푸셔(Pusher), 이 푸셔의 장력조절을 위한 스프링, 상기 푸셔가 설치되는 푸셔 고정지그 및, 상기 푸셔의 중공부에 배치되어 연료전지 분리판의 두께와 유로 깊이를 측정하는 측정유닛의 측정팁으로 이루어지되, 상기 측정팁을 푸셔의 상하이동에 의해 이 푸셔에서 돌출 및 함몰되어지는 구조로 되어 있다.In order to achieve the above object, the present invention provides a device for measuring the thickness and flow path depth of a fuel cell separating plate having a flow path using a measuring unit, the lower plate jig on which the fuel cell separating plate is seated, and the lower plate jig. Hollow cylindrical pusher to closely contact the measuring part of the fuel cell separating plate seated, spring for tension control of the pusher, pusher fixing jig in which the pusher is installed, and the fuel cell is disposed in the hollow part of the pusher It consists of a measuring tip of the measuring unit for measuring the thickness of the plate and the depth of the flow path, and the measuring tip is projected and recessed in the pusher by the shangdong of the pusher.

상기와 같이 본 발명에 따른 유로가 있는 연료전지 분리판의 두께와 유로 깊이 측정장치는 연료전지 분리판의 두께와 유로 깊이를 측정할 때 비파괴 방식으로 신속하고 정확하게 측정하여 측정 데이터를 얻을 수 있는 장점을 지니게 된다.As described above, the thickness and flow path depth measuring apparatus of the fuel cell separator having a flow path according to the present invention has the advantage of quickly and accurately measuring the non-destructive method to obtain the measurement data when measuring the thickness and flow path depth of the fuel cell separator. Will have.

이하, 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 유로가 있는 연료전지 분리판의 두께와 유로 깊이를 측정하는 장치를 나타낸 개략적인 구성도이다.1 is a schematic configuration diagram showing an apparatus for measuring the thickness and the flow path depth of a fuel cell separator having a flow path according to the present invention.

앞서 설명한 바와 같이 성형된 연료전지 분리판(1)은 약간의 휨이 발생하기 때문에 이 휨 문제를 해결하면서 연료전지 분리판(1)의 두께와 유로를 비파괴 방식으로 측정할 수 있도록 되어 있다.Since the fuel cell separator 1 molded as described above has a slight warpage, it is possible to measure the thickness and the flow path of the fuel cell separator 1 in a non-destructive manner while solving this warpage problem.

즉, 본 발명은 유로가 있는 연료전지 분리판(1)의 두께와 유로 깊이를 측정유닛(2)을 이용하여 측정하는 장치에 있어서, 상기 연료전지 분리판(1)이 안착되는 하판지그(3)와, 이 하판지그(3)에 안착되는 연료전지 분리판(1)의 측정부위를 밀착시키는 중공 원통형의 푸셔(4), 이 푸셔(4)의 장력조절을 위한 스프링(5), 상기 푸셔(4)가 설치되는 푸셔 고정용 지그(6) 및, 상기 푸셔(4)의 중공부(7)에 배치되어 연료전지 분리판(1)의 두께와 유로 깊이를 측정하는 측정유닛(2)의 측정팁(8)으로 이루어지되, 상기 측정팁(8)은 푸셔(4)의 상하이동에 의해 이 푸셔(4)에서 돌출 및 함몰되어지는 구조로 되어 있다.That is, the present invention is a device for measuring the thickness and the depth of the flow path of the fuel cell separation plate 1 with the flow path using the measuring unit 2, the lower plate jig (3) on which the fuel cell separation plate 1 is seated ), A hollow cylindrical pusher 4 for closely contacting the measuring portion of the fuel cell separating plate 1 seated on the lower plate jig 3, a spring 5 for tension control of the pusher 4, and the pusher (4) of the pusher fixing jig (6) and the measuring unit (2) disposed in the hollow portion (7) of the pusher (4) to measure the thickness and flow path depth of the fuel cell separation plate (1). It consists of a measuring tip (8), the measuring tip (8) has a structure that protrudes and recessed in the pusher (4) by the shangdong of the pusher (4).

여기서 상기 측정팁(8)이 푸셔(4)의 중공부(7) 내에 배치되어 있어서, 이 푸셔(4)가 스프링(5)을 압착시키면서 후퇴할 때 이 측정팁(8)은 푸셔(4)의 중공부(7)에서 돌출되어 연료전지 분리판(1)에 접촉되기 때문에 이 연료전지 분리판(1)의 두께와 유로 깊이를 측정할 수가 있다.The measuring tip 8 is here arranged in the hollow 7 of the pusher 4 so that the measuring tip 8 is pusher 4 when the pusher 4 is retracted while pressing the spring 5. Since it protrudes from the hollow portion 7 of the fuel cell separating plate 1 and contacts the fuel cell separating plate 1, the thickness and the flow path depth of the fuel cell separating plate 1 can be measured.

이어 본 발명의 작용 설명을 한다.Next, the operation of the present invention will be described.

먼저 상기 측정유닛(2)에 연결된 측정팁(8)과 푸셔(4)를 이용하여 측정 대상 물인 연료전지 분리판(1)이 안착되는 하판지그(3)의 평탄도를 1차적으로 측정한 후 연료전지 분리판(1)을 도 2(A)와 같이 올려놓고 측정하게 된다.First, the flatness of the lower plate jig 3 on which the fuel cell separation plate 1, which is the object to be measured, is mounted is first measured by using the measuring tip 8 and the pusher 4 connected to the measuring unit 2. The fuel cell separator 1 is placed and measured as shown in FIG.

즉, 도 2(B)와 같이 푸셔(4)가 먼저 연료전지 분리판(1)의 측정부위를 맞닿아 이 연료전지 분리판(1)을 하판지그(3)에 밀착시키게 되는바, 이로 인하여 연료전지 분리판(1)의 휨 문제를 해결하게 되고, 이 같이 푸셔(4)가 하판지그(3)에 연료전지 분리판(1)을 밀착시킨 상태에서 측정유닛(2)에 연결된 측정팁(8)이 푸셔(4)의 중공부(7)에서 돌출되어 연료전지 분리판(1)에 접촉되어 이의 두께와 유로 깊이를 측정하도록 되어 있다.That is, as shown in FIG. 2B, the pusher 4 first contacts the measurement portion of the fuel cell separator 1 so that the fuel cell separator 1 is brought into close contact with the lower plate jig 3. The bending problem of the fuel cell separating plate 1 is solved. In this way, the pusher 4 is connected to the measuring unit 2 with the fuel cell separating plate 1 closely attached to the lower plate jig 3. 8) protrudes from the hollow portion 7 of the pusher 4 and contacts the fuel cell separator 1 so as to measure its thickness and flow path depth.

여기서 상기 푸셔(4)는 측정하는 연료전지 분리판(1) 주위를 링 형태로 눌러주면서 하판지그(3)에 연료전지 분리판(1)을 밀착시키는 역할을 수행하게 되든데, 이때 이 푸셔(4)는 스프링(5)을 압착시키면서 후퇴하게 된다.Wherein the pusher (4) is to press the circumference of the fuel cell separating plate (1) to measure while serving to close the fuel cell separating plate (1) to the lower plate jig (3), the pusher ( 4) is retracted while pressing the spring (5).

한편, 상기 푸셔(4)의 장력을 조절하는 스프링(5)의 갯수와 재질은 측정 대상물인 연료전지 분리판(1)의 경도와 휨 정도에 따라 다양하게 조절할 수 있음은 물론이다.On the other hand, the number and material of the spring (5) for adjusting the tension of the pusher (4) can of course be variously adjusted according to the hardness and the degree of bending of the fuel cell separation plate (1) to be measured.

한편, 본 발명은 일예로 연료전지 분리판에서 이의 두께와 유로 깊이를 측정하는 장치를 설명하였지만, 휨이 발생한 측정 대상물의 다양한 판에서 이 판의 두께와 유로 깊이 등을 측정할 때에는 적용하여 사용할 수가 있음을 알 수 있다.On the other hand, the present invention has been described an apparatus for measuring the thickness and the flow path depth of the fuel cell separator as an example, but it can be used to measure the thickness and the flow path depth of the various plates of the measurement object that the warpage has occurred It can be seen that.
