인듐링의 봉착법Sealing Indium Ring

도면은 본발명의 방법을 수행하는 장치의 개략적인 사시도이다.The figure is a schematic perspective view of an apparatus for carrying out the method of the invention.

본 발명은 유도 전압으로 인한 2차 전류에 의해 발생되는 쥬울열을 이용하여 비디콘형 촬상관의 면판과 벌브를 인듐링으로 봉착하는 방법에 관한 것이며, 촬상관의 면판부착은 물론 이와 유사한 방면에 응용할 수 있다.The present invention relates to a method of sealing a face plate and a bulb of a beacon type imaging tube with an indium ring using joule heat generated by a secondary current caused by an induced voltage, and can be applied to a similar aspect as well as to attaching the face plate of the imaging tube. .

통상 인듐링을 봉착시킬때는 직접 열을 가하거나 고주파를 인가하는데 이때 열의 전달이 고르지 않아 면판과 벌브는 서로 부분적으로는 잘 밀착되지 못하는 경우가 있었다. 또한 직접가열하는 방법에 의할 경우 면판에 이미 제작된 광도전성물질들이 열을 받아 전기적 특성을 변화시키는 문제가 발생할 수가 있었다.In general, when sealing an indium ring, direct heat is applied or high frequency is applied. At this time, heat is uneven, and thus the face plate and the bulb may not be in close contact with each other. In addition, the direct heating method may cause a problem of changing the electrical characteristics of the photoconductive materials already produced on the face plate receives heat.

본 발명은 이와 같은 문제점을 해결하도록 한 것이다. 즉 인듐링 자체에서만 발열 현상이 있게하여 면판에 미리 증착된 광도전성물질에 대해서는 전혀 전기적 특성상의 변화를 일으키지 않게 하고, 인듐링 자체에 발열 현상이 고르게 발생하도록 하므로 부분적 가열에 따른 면판과 벌브가 잘 밀착되지 않게하는 문제를 해결하였다.The present invention is to solve this problem. In other words, the heat generation phenomenon occurs only in the indium ring itself, so that the photoelectric material previously deposited on the face plate does not cause any change in electrical properties, and the heat generation phenomenon occurs evenly on the indium ring itself. It solved the problem of not sticking.

이를 위하여 본 발명은 유도전압을 이용하도록 변압기 철심을 사각의 외철형으로 형성시키면서 일측에는 코일 수정수의 권선수로 감겨져 있고 타측은 촬상관이 삽입되고 면판이 촬상관과 대향하여 놓이고 인듐링을 가진 원형의 알루미늄판이 설치될 수 있는 구조로 되면서 촬상관의 하부측과 면판과는 다소의 간극을 갖도록 한 구조로 이루어져 있다.To this end, the present invention forms a transformer iron core in a rectangular outer iron shape to use an induction voltage, while one side is wound with the number of turns of coil correction water, and the other side is inserted into an image tube and a face plate is placed opposite to the image tube, and has an indium ring. The aluminum plate of the structure is to be installed, and the lower side of the imaging tube and the surface plate has a structure so as to have a little gap.

본 발명은 인듐링에 직접 열을 가하여 면판과 벌브를 봉착시킬때 일어나는 제반 문제점들을 해결하면서 인듐링 봉착을 용이하게 하는 방법을 제공하는데 있다. 그러므로 본 발명은 벌브를 변압기 철심의 우측 소정 부위에 형성한 간극을 중심으로 상측으로 벌브를 삽입하고 하측 철섬위에는 면판을 올려놓고 면판과 벌브 사이에는 원형의 알루미늄판 상에 있는 인듐링이 벌브와 면판사이를 밀봉하도록 위치되게 하고, 변압기에 전압을 인가하므로 본 발명의 방법이 수행된다.The present invention is to provide a method for facilitating the sealing of the indium ring while directly solving the problems encountered when sealing the face plate and the bulb by applying heat directly to the indium ring. Therefore, in the present invention, the bulb is inserted to the upper side centering on the gap formed at the right side of the transformer core by placing the bulb on the lower iron island and the indium ring on the round aluminum plate between the plate and the bulb is the bulb and the face plate. The method of the invention is carried out by positioning it to seal the gap and applying a voltage to the transformer.

본 발명의 방법을 수행하는 장치에 대한 도면에 의거하여 본 발명을 상세히 기술하면 다음과 같다.The present invention will be described in detail with reference to the drawings of an apparatus for performing the method of the present invention.

본 발명의 방법은 도면에 도시와 같이 비디콘 촬상관을 제조하는데 있어서, 벌브(1)와 광도전성 물질(3)을 증착한 면판을 인듐링(4)으로 밀봉시키는 것으로써, 변압기(10)의 사각으로 이루어진 외철형 철심(6)의 좌측에는 코일(7)이 소정권선수 (N1)로 감기고, 코일(7)일단부와 타단부가 교류전원(8)으로 연결되어 있다. 또한 변압기(10)는 철심(6)의 우측 소정위치에 형성한 간극(9)에 대하여 상측으로 벌브(1)가 삽입되게 하고 하측에는 광도전성 물질을 증착한 면판(2)이 위치 되게 하면서 인듐링(3)을 가진 원형의 알루미늄판(5)이 도시와 같이 위치된다.According to the method of the present invention, in manufacturing a videoconducting tube as shown in the figure, the insulator ring (4) is sealed by sealing the face plate on which the bulb (1) and the photoconductive material (3) are deposited. On the left side of the rectangular iron core 6 made of a square, a coil 7 is wound with a predetermined winding N 1 , and one end and the other end of the coil 7 are connected to an AC power source 8. In addition, the transformer 10 allows the bulb 1 to be inserted upward with respect to the gap 9 formed at a predetermined position on the right side of the iron core 6, and to place the face plate 2 on which the photoconductive material is deposited on the lower side. A circular aluminum plate 5 with a ring 3 is positioned as shown.

이에 따라 본 발명은 다음과 같은 원리에 따른다.Accordingly, the present invention is in accordance with the following principle.

즉 전류 I가 흐르는 길이 l인 도체로부터 γ만큼 떨어진 점에서의 자장 B의 크기는 실험적으로That is, the magnitude of the magnetic field B at a point γ away from the conductor l of the length l through which the current I flows is experimentally

각 θ는 전류의 방향과 그 점을 향하는 동경 벡터 사이의 각이다.The angle θ is the angle between the direction of the current and the longitude vector toward that point.

자장은 전류의 방향과 동경 벡터를 포함하는 평면에 수직이며 Weber/m2로 측정된다. 암페어 법칙에 따르면 전류 I에 의한 자장은 전류에 정비례한다. 따라서, (1)식의 다른 모든 인자는 회로의 기하학적 조건에만 의존한다.The magnetic field is perpendicular to the plane containing the direction of the current and the radial vector and measured in Weber / m 2 . According to the ampere law, the magnetic field due to current I is directly proportional to the current. Therefore, all other factors of equation (1) depend only on the geometrical conditions of the circuit.

따라서 둘러싸는 전 자속은 자장에다 회로의 면적 A를 곱한 것으로 주어진다. (1)식을 이용하면 자속은The enclosing magnetic flux is therefore given by the magnetic field multiplied by the area A of the circuit. Using the formula (1), the magnetic flux

(4)식에 의하면 어느 회로에서나 전류가 시간에 따라서 변화하면 그 회로에는 기전력이 유도된다. 이때 유도되는 기전력의 크기는 전류의 변화율과 회로의 인덕턴스로 정해지는 회로의 기하학적 조건에 의존한다. 그림에서 1차측에 감은 코일(7)권선수를 N1이라 하면 변압기의 용량은 1차측과 2차측이 모두 같은값이고 유기되는 전압은 감은 권선비에 비례하므로 2차 측에 유도되는 전류 량은This is called Faraday's law. According to Equation (4), when current changes with time in any circuit, electromotive force is induced in the circuit. The magnitude of the induced electromotive force depends on the geometric conditions of the circuit, which is determined by the rate of change of the current and the inductance of the circuit. In the figure, if the coil (7) wound on the primary side is N 1 , the capacity of the transformer is the same value on both the primary and secondary sides, and the induced voltage is proportional to the winding ratio, so the amount of current induced on the secondary side is

이렇게 발생된 열에 의해 In은 녹게 되고 벌브(1)의 하중에 의해 면판(2)과 밀착하게 된다. 이때 만약 벌브(1)의 중량이 크지 못하면 외부에서 벌브(1)를 눌러 주어도 좋다. 그러므로 본 발명은 벌브(1)를 철심(6)우측에 형성한 간극(9)에 대하여 상측으로 벌브(1)를 삽입하고 하측으로 철심(6)평면상에 면판(2)을 올려논 다음 알루미늄판 (5)상에 위치시킨 인듐링(4)이 벌브(1)의 벽과 면판(2)의 원주부 사이에 끼이도록하여서, 전원(8)을 온 시키면 철심(6)의 좌측에 권선된 코일(7)의 권선수(N1)와 인듐링에 의한 회로 루우프를 형성하므로 얻어지는 1회의 N2값이 정해지므로 식(7)에 의한 소정의 열이 발생되게 하며 인듐링(4)을 발열시키고 벌브(1)와 면판(2)를 밀봉되게 한다.The heat generated in this way melts I n and comes into close contact with the face plate 2 by the load of the bulb 1. At this time, if the weight of the bulb (1) is not large, you may press the bulb (1) from the outside. Therefore, in the present invention, the bulb 1 is inserted into the bulb 1 upwards with respect to the gap 9 formed on the right side of the iron core 6, and the bottom plate 2 is lifted up on the iron core 6 plane downward. The indium ring 4 placed on the plate 5 is sandwiched between the wall of the bulb 1 and the circumference of the face plate 2 so that when the power source 8 is turned on, it is wound on the left side of the iron core 6. Since the number of windings N 1 of the coil 7 and the circuit loop formed by the indium ring are determined, the value of N 2 obtained is determined so that a predetermined heat is generated by the formula (7) and the indium ring 4 is generated. And seal the bulb (1) and the face plate (2).
