본 발명은 계기 보빈 조립라인의 고주파 유도가열 납땜기에 관한 것으로, 특히 소재의 국부가열에 적당하도록 하는 고주판 유도 가열장치에 관한 것이다.The present invention relates to a high frequency induction heating soldering machine of an instrument bobbin assembly line, and more particularly, to a high plate induction heating apparatus that is suitable for local heating of a material.

종래에도 계기 보빈 조립라인에 2줄로 감긴 코일을 구비한 고주파 유도가열장치를 설치하여 보빈의 땜납을 행하였다. 2줄 감긴 코일을 구비한 고주파 유도 가열장치에서 납땜작업을 하기 위하여는 첫째: 단자의 가열과 둘째: 적정한 위치의 땜납융착, 셋째: 땜납포인트 이외의 부분을 가열해서는 안 되는데, 2줄감김 코일에서는 자속밀도는 2배로 증가하였으나, 열 영향부가 광범위 하기 때문에 공급땜납을 원거리에서 녹여 정확한 위치에서 땜납이 이루어지지 않으며, 그 열에 의하여 포인트 샤프트와 프라스틱 재질의 바디가 녹아버리는 현상이 발생하였다.Conventionally, a high frequency induction heating apparatus having a coil wound in two lines is installed on an instrument bobbin assembly line to solder a bobbin. In order to solder in a high frequency induction heating system with two-coil wound coils, firstly: heat the terminal and secondly, solder the solder in the proper position, and thirdly, do not heat any part other than the solder point. The magnetic flux density was doubled, but because of the wide range of heat affected zones, the supply solder was melted at a long distance and the solder was not formed at the correct position. The heat melted the point shaft and the plastic body.

이것은 단자 주변에 넓게 분포된 자기장의 영향에 의한 것이어서 본 발명은 이러한 자기장이 단자 주변에서만 형성되도록 하여 첫째: 포인트 샤프트주변에서는 자기장을 저하 시키고, 둘째: 4단자 주변에서는 자기장이 증폭되는 구성을 제공함을 목적으로 한다.This is due to the influence of the magnetic field widely distributed around the terminals, so that the present invention allows such magnetic fields to be formed only around the terminals. First, the magnetic field is reduced around the point shaft, and the second: the magnetic field is amplified around the four terminals. The purpose.

상기의 목적을 달성하기 위하여는 코일의 감김구조를 이하의 구성으로 형성하는 것이 바람직하다.In order to achieve the above object, it is preferable to form the coil winding structure in the following configuration.

계기 보빈의 단자에 땜납을 하기 위하여 사용하는 고주파 유도가열기에 사용되는 코일(6)을 형성함에 있어서,사각부재로 형성되는 절연부재(1)의 네귀에 조립을 위한 통공(1a)을 뚫어 형성하고, 그 중앙을 원형상으로 파내어 오목한 홈(2)을 형성하면서 홈(2)의 바닥중앙에 포인트 샤프트(7)의 삽입지지를 위한 축공(3)을 뚫어 형성하고, 그 주변으로 땜납을 하기 위한 단자공(4)들을 사방으로 뚫어 형성한다.In forming the coil 6 used for the high frequency induction heater used for soldering the terminals of the instrument bobbin, the four holes of the insulating member 1 formed of a square member are drilled to form a through hole 1a for assembly. The core is drilled into a circular shape to form a concave groove 2, and the shaft hole 3 for insertion support of the point shaft 7 is formed in the center of the bottom of the groove 2, and soldered to the periphery thereof. The terminal holes (4) for drilling in all directions to form.

상기의 구성으로 이루어지는 절연부재(1)에는 코일(6)을 설치하는데, 상기 코일(6)의 감김상태를 설명하면 하나의 동선이 단자의 주변을 감싸는 형으로 진입되어 단자를 감싸면서 빠져 나간뒤 소정의 위치에서 진입된 동선을 지나도록 절곡하고, 다음의 단자측으로 이동하여 다음의 단자측으로 진입하여 단자를 감싸면서 빠져나가 소정의 위치에서 진입된 동선을 지나가도록 절곡하여, 다음의 단자측으로 이동되는 상태로 각 단자의 위치를 감싸도록 한다.The coil 6 is installed in the insulating member 1 having the above-described configuration. When the coil 6 is described in a wound state, a single copper wire enters a shape that surrounds the periphery of the terminal and exits while wrapping the terminal. It is bent to go through the copper wire entered at a predetermined position, moves to the next terminal side, enters the next terminal side, wraps up the terminal, exits, bends to pass the copper wire entered at the predetermined position, and is moved to the next terminal side. Enclose the position of each terminal in the state.

상기의 구성으로 이루어지는 본 발명은 절연부재(1)의 중앙에 형성된 홈(2)의 축공(3)으로 포인트 샤프트(7)를 삽입하고, 그 주변에 뚫린 각각의 단자공(4)으로는 계기 보빈의 단자(8)을 삽입한 다음, 이들의 각 단자에 고주파 유도 가열용 코일(6)을 연결한다.According to the present invention having the above structure, the point shaft 7 is inserted into the shaft hole 3 of the groove 2 formed in the center of the insulating member 1, and each terminal hole 4 drilled around the instrument After inserting the terminal 8 of the bobbin, the coil 6 for high frequency induction heating is connected to each of these terminals.

상기의 코일 연결상태는 제2도의 상태로 이루어진다.The coil connection state is made in the state of FIG.

이와 같은 본 고안의 고주파 유도 가열장치는 코일(6)이 각 단자의 주위를 감싸는 상태를 이루고, 전체적인 원주는 단자(8)들에서 멀어지는 상태가 되므로 이에 전류를 보내면 임의순간(t)에 소정의 크기(i)전류에서 dt 순간 di 만큼의 전류변화가 발생할 때 자기장(또는 자속밀도)은 i에 비례하는 세기를 형성하고, 이때의 변화량 만큼 ← 방향으로 이동하여 피가열체(도체)에 벡터전류를 형성시킨다.The high frequency induction heating apparatus of the present invention forms a state in which the coil 6 wraps around each terminal, and the entire circumference becomes a state away from the terminals 8. The magnetic field (or magnetic flux density) forms an intensity proportional to i when the current change by dt moment di occurs in the magnitude (i) current, and moves in the direction ← by the amount of change at this time, so that the vector current To form.

즉, 가열이 필요한 영역1의 경우는 단자를 감싸는 부분의 코일과 다음의 단자측으로 이어지는 부분의 전기장 방향이 증폭되는 상횡에 놓여지고, 가열되어서는 안 되는 영역2의 경우에는 단자를 감싸는 부분과 다음의 단자측으로 이어지는 전기장 방향이 상쇄되는 상황에 놓여진다.That is, in the case of the area 1 requiring heating, the coil of the part surrounding the terminal and the direction of the electric field of the part leading to the next terminal side are placed above and above the amplification. In the area 2 which should not be heated, the part surrounding the terminal and the next The electric field direction leading to the terminal side of is canceled.

한편, 피가열체에 생성된 전류는 스스로의 영향으로 코일(6)의 표면에만 흘러 국부단면에 과대전류가 흐르는 현상(표피효과)이 발생하여 피가열체의 표면만 급격히 가열되는 상태를 이룬다.On the other hand, the current generated in the heated object flows only on the surface of the coil 6 under its influence, and an excessive current flows in the local cross section (skin effect) to occur, and thus only the surface of the heated object is rapidly heated.

상기와 같은 표피효과에 의하여 땜납은 단자에 근접한 위치에 도달되어야만 융용되어 납땜이 이루어지는 것이다.Due to the skin effect as described above, the solder is melted only when it reaches a position close to the terminal to be soldered.

이상에서와 같이 본 발명은 절연부재의 홈에 국부가열이 가능한 고주파 유도가열의 코일을 효율적인 구조로 설치하는 것에 의하여 각 단자에 에너지를 집속할 수 있으며 이로 인해 공급땜납이 단자의 근거리에서만 용융되어 단자에 융착되며, 특히 가열되어서는 안 되는 바디와 포인트 샤프트(7)부분이 열로부터 보호되어 사용수명의 연장과 사용기능이 향상되는 이점이 있는 것이다.As described above, the present invention can focus energy on each terminal by installing a coil of high frequency induction heating capable of local heating in the groove of the insulating member. It is fused to, especially the body and the point shaft (7) portion that should not be heated is protected from heat, there is an advantage that the service life is extended and the function is improved.
