본 발명은 무연 땜 용 인두에 관한 것으로, 종래에 주로 사용하던 세라믹 히터 방식은 느린 보상 온도로 용융점이 높은 무연 땜에는 부적합하고, 또한 기존의 고주파 유도 가열방식은 일반 세라믹 히터 방식에 비하여 보상온도가 빠른 장점이 있다. 그러나 스마트 히터(큐리 효과를 이용한 방식)는 제조과정에서 일방적으로 결정된 단순한 1개의 온도만을 발열제어 할 수밖에 없고, 일체형 카트리지 방식으로써 충격에 의한 카트리지가 쉽게 파손되는 점과 무연 땜 작업시 팁의 교환 주기 가 짧아 고 비용의 경제적인 문제점 등이 있다. 그리고 기존의 센서를 이용한 고주파 유도 가열 방식은 온도의 가변성은 갖고 있었으나, 역시 무연 땜 작업시 인두기 팁의 교환 주기가 짧아 경제적으로 고 비용의 문제점과 작업 환경 변화에 따라 온도설정을 매번 변경하는 불편함과 부정확한 온도가 문제점이었다, 그래서 지금까지는 정확한 온도를 확인하기 위하여 별도의 온도계를 이용하여 인두기 팁의 온도를 측정하여 정확성을 확인해야만 하는 불편함이 있었다.The present invention relates to a lead-free soldering iron, the conventional ceramic heater method is a slow compensation temperature is unsuitable for lead-free solder having a high melting point, and the conventional high frequency induction heating method has a compensation temperature compared to the general ceramic heater method There is a quick advantage. However, the smart heater (method using the Curry effect) can only control the heating of only one temperature determined unilaterally during the manufacturing process, and the cartridge is easily damaged by the impact due to the one-piece cartridge method and the tip replacement cycle during lead-free soldering. Short and high cost economic problems. In addition, the high frequency induction heating method using the conventional sensor had a temperature variability, but in addition, the replacement cycle of the soldering iron tip during the lead-free soldering operation is economically expensive, and it is inconvenient to change the temperature setting every time according to the change of working environment. Inaccurate temperature has been a problem, and so far, there has been inconvenience of having to check the temperature by measuring the temperature of the soldering iron tip using a separate thermometer to confirm the correct temperature.
따라서, 본 발명의 목적은 무연 땜 작업시 요구되는 손실 온도의 빠른 보상 온도와 팁의 교환 주기를 길게 하여 경제적인 효과와 작업 상황에 따라서 적절한 온도를 원터치로 쉽게 가변하고, 정확한 온도를 제공함으로써 작업 능률을 향상하고, 작업 불량을 최소화하는데 그 목적이 있다. 상기와 같은 문제를 해결하기 위하여 무연 땜 작업시 필요한 빠른 보상온도에 적합한 기존의 고주파를 이용한 발열방식으로써 인두기가 사용하지 않고 인두기 받침에 보관될 때를 인공지능으로 감지하여, 디지털 제어기로 수면온도를 설정,제어함으로써 팁이 높은 온도상태에서 산화됨을 막아 주어 팁의 교환 주기가 길어짐으로 고 비용의 소모품 비용을 절감함으로써 경제적 효과를 얻고, 디지털온도 제어기에 사용자가 원하는 작업 환경에 맞게 3개의 온도를 설정하여 원 터치로 신속하고 간편하게 온도를 선택함으로써 작업 능률을 향상시키고, 100분의 1도 단위로 정확하게 온도를 디지털 제어함으로써, 필요 이상의 열량으로 인한 부품 파손이나 PCB손상의 작업불량을 최소화하는 인공지능 수면 제어 장치와 3개 온도 원터치 제어 장치로 구성된 고주파 디지털 제어 인두기 를 제공하는 데 있다.Accordingly, an object of the present invention is to quickly change the compensation temperature of the loss temperature required for the lead-free soldering operation and to prolong the exchange interval of the tip to easily change the appropriate temperature with one touch according to the economic effect and the working situation, and to provide the correct temperature The purpose is to improve efficiency and minimize work defects. In order to solve the above problems, the existing high frequency heating method suitable for the fast compensation temperature required for lead-free soldering work is artificially detected when the iron is stored in the iron support without using the iron, and the sleep temperature is digitally controlled. By setting and controlling the tip, it prevents the tip from oxidizing at high temperature state, and the exchange interval of the tip is long, so it is economical by reducing the cost of expensive consumables, and it is possible to set three temperatures in the digital temperature controller according to the user's desired working environment. It improves work efficiency by selecting temperature quickly and easily with one touch, and precisely digitally controls the temperature in hundredths of a degree, so as to minimize work damage or PCB damage caused by excess heat. High pressure consisting of control unit and three temperature one-touch control unit To provide a digital wave control iron.

이하, 첨부한 도면을 참조하여 본 발명의 바람직한 실시 예를 살펴보고자 한다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.
도 1은 본 발명에 의한 인두기 발열 제어장치를 도시한 회로블록도면이고,1 is a circuit block diagram showing a soldering iron heating control device according to the present invention,
도 2는 본 발명에 의한 인두기 받침대와 본체를 연결한 상태를 나타낸 사시 도이며, 도 3은 본 발명에 의한 인두기 본체의 전면 스위치 구성을 나타낸 사시도로써, 상기 도 1에서 고주파 발진기(4)는 400KHz의 주파수를 발진하여 파워앰프(3)에서 전력 증폭하여 인두기 본체의 커넥터를 통해 인두기 발열코일(2)에 인가되고, 발열코일(2) 안쪽으로 자성체인 인두기 팁(1)을 삽입하면, 발열 코일(2)에 유도 전류가 흐르게 되며 이 전류에 의한 도체인 인두기 팁에서 줄(Joule)열이 발생한다. 이때 상기에 인두기 팁(1)과 발열 코일(2)사이에 온도 센서가 위치하며 감지된 온도를 프리 앰프(8)에 인가하여 증폭한 후에 디지털 제어기(5)에 인가되고, 상기 디지지털 제어기에 내장된 A/D 컨버터에서 디지털 신호로 변환하여 100분의1초 단위로 설정된 온도 값(100분의1도 단위)과 상호 비교한 후 그에 상응하는 스위칭 제어 신호를 출력하여 고주파 발진기를 개폐하여 정밀한 온도를 유지하게 된다.Figure 2 is a perspective view showing a state connecting the iron base and the main body according to the present invention, Figure 3 is a perspective view showing the front switch configuration of the iron body main body according to the present invention, the high-frequency oscillator (4) in Figure 1 is 400KHz When oscillating the frequency of the power amplifier (3) and amplified the power is applied to the iron generator heating coil (2) through the connector of the iron body, the magnetic iron iron tip (1) is inserted into the heating coil (2), heating coil Induction current flows in (2) and Joule heat is generated at the tip of the soldering iron. At this time, a temperature sensor is positioned between the soldering iron tip 1 and the heating coil 2 and the amplified by applying the sensed temperature to the preamplifier 8, and then applied to the digital controller 5, the digital controller It converts into digital signal in built-in A / D converter and compares with temperature value set in hundredths of a second (units of hundredths) and outputs the corresponding switching control signal to open and close the high frequency oscillator. Maintain a precise temperature.
상기 도 2에서 인두기가 사용하지 않고 보관될 때 인두기 받침대(1) 내부에 인공감지 센서와 인두기 바디에 접지(GND)가 접촉하여 감지된 신호를 인두기 받침대 뒷면 에 커넥터를 통하여 연결선에 인가되어, 인두기 본체 후면에 연결 커넥터로 연결되고, 디지털 제어기(MCU)에 인가된다. 수면 제어 설정(SLEEP MODE)은 10분~90분까지 10분 간격으로 설정 가능하고, 설정된 시간이 경과 되면, 자동으로 온도 설정 값을 200도로 낮춘다. 그리고 인두기가 인두기 받침대 내부의 인공지능감지 센서에서 접촉이 떨어질 때는 즉시 이전의 설정 온도 값으로 전환하여 고주파 유도 가열의 장점인 빠른 열 복원으로 설정된 온도에 복원하게 된다.In FIG. 2, when the iron is stored without using the iron, the signal sensed by the ground (GND) contacting the artificial sensor and the iron body inside the iron holder 1 is applied to the connection line through the connector on the back of the iron holder, the iron It is connected to the back of the main body with a connector and is applied to the digital controller (MCU). SLEEP MODE can be set in 10 minute intervals from 10 minutes to 90 minutes, and when the set time has elapsed, the temperature setting value is automatically lowered to 200 degrees. And when the soldering machine loses contact with the AI sensor inside the iron stand, it immediately switches to the previous set temperature and restores it to the temperature set by fast heat recovery, which is the advantage of high frequency induction heating.
상기 도 3에서 인두기 본체와 인두기 바디에 발열부를 연결하는 커넥터(3)와, 전원을 켜고 끄는 전원 스위치(4)와, 온도를 표시하는 디스플레이(5)로 구성되어 있고, 인두기 본체(1)의 전면에 3개의 온도를 설정하는 원터치 스위치(2)를 작업자가 설정한 온도를 원터치로 손쉽게 변경하여 작업할 수가 있다.3 is composed of a connector (3) for connecting the heating unit to the iron body and the iron body, a power switch (4) for turning on and off the power, and a display (5) for displaying the temperature, The one-touch switch 2, which sets three temperatures on the front side, can easily work by changing the temperature set by the operator to one-touch.
