Description

온도센서를 이용한 고주파 발열 인두조절기{Radio Frequency Thermal Iron Controller Using Temperature Sensor}Radio Frequency Thermal Iron Controller Using Temperature Sensor

기존에 주로 사용하고 있는 세라믹 히터 방식의 인두기는 팁에 열을 저장하거나 축적된 열을 사용하는 고정파워 시스템으로 PCB와 전자 부품에 열로 인한 손상이 높다. 그리고 세라믹 히터 팁이 면적이 넓은 PCB의 납땜 부위에 열을 전달할 때 열을 잃은후(200 ∼ 250°C) 히터에 의해 재 가열 되는 시간(60∼120sec)이 길어서 부품에 열을 전달하여 손상을 초래할 수 있는 단점이 크다. 또한, 외국에서 보급되어 사용되고 있는 인공지능형 고주파 발열 인두 조절기는 온도 보정을 위해 카트리지(구리와 자성 합금체로 구성된것) 교환 방식을 사용하는데 고가의 교환 비용과 충격에 의한 카트리지의 파손이 심각한 문제점을 갖고 있다.Ceramic heater-type irons, which are commonly used, are fixed power systems that store heat at the tip or use accumulated heat, and heat damage to the PCB and electronic components is high. And when the ceramic heater tip transfers heat to the soldered part of the large PCB, the heat is lost (200-250 ° C) and then reheated by the heater (60-120 sec). The disadvantages that can result are great. In addition, the intelligent high frequency heating iron controller used in foreign countries uses a cartridge (consisting of copper and magnetic alloy) for temperature correction, which has a serious problem of expensive replacement cost and damage to the cartridge due to impact. have.

본 발명은 느린 가열시간, 느린 열보상, 납땜 온도의 변화등으로 인한 납땜 접합 강도와 환경에 악영향을 끼치는 유연납 사용 등의 문제점을 가지는 직접 가열 방식의 전기 인두기의 문제점을 개선하기 위하여 고주파 유도 가열 방식을 사용한다.The present invention provides a high frequency induction heating to improve the problems of the direct heating type electric soldering iron, which has problems such as the solder joint strength and the use of a flexible lead that adversely affects the environment due to a slow heating time, a slow thermal compensation, a change in the solder temperature, and the like. Use the method.

고주파 유도 가열 방식은 와전류 손실과 히스테리시스 손실을 이용한다. 와전류 손실이란, 회로를 관통하는 자속이 시간에 따라 변화한다든가 또는 자속과 도체가 상대적으로 운동하여 회로내의 자속을 시간적으로 변화시키면 이 변화를 막기 위하여 회로 내에 부분적으로 형성된 임의의 폐 회로를 따라 전류가 유도되며, 이 전류에 의한 Joule열을 와전류 손실이라 말한다. 히스테리시스 손실이란, 자성체에 가해지는 자계의 변화에 의한 자화율의 변화를 히스테리시스라 하며, 자계의 변화에 의해 에너지가 발생하며, 그 에너지가 열로 변한것을 말한다.High frequency induction heating uses eddy current losses and hysteresis losses. Eddy current loss is the current along any closed circuit formed partially within the circuit to prevent this change if the magnetic flux through the circuit changes over time or if the magnetic flux in the circuit changes in time as the magnetic flux and the conductor move relatively. Is induced, and Joule heat by this current is called eddy current loss. Hysteresis loss is a change in the susceptibility caused by a change in the magnetic field applied to the magnetic body is called hysteresis, energy is generated by the change in the magnetic field, the energy is converted into heat.

고주파 유도 가열은 와전류 손실과 히스테리시스 손실을 이용하지만, 와전류손실이 히스테리시스 손실보다도 중요하게 작용하며, 유도 가열의 발열량은 그 도체의 저항과 흐르는 전류에 의해 열이 발생한다. 이 발열량은 흐르는 전류의 방향에 관계없이 전류의 2승에 비례한다.High frequency induction heating uses eddy current loss and hysteresis loss, but eddy current loss is more important than hysteresis loss, and the calorific value of induction heating generates heat due to the resistance of the conductor and the flowing current. This amount of heat is proportional to the power of the current regardless of the direction of the current flowing.

본 발명으로 구성된 시스템은, 온도 센서에 의해 고주파 발생부에서 발생한 고주파 전류를 인두 바디의 고주파 코일에 흐르게 함으로서, 인두 팁을 고주파 유도 가열 하는 방식으로 동작한다. 즉, 납땜 부위에 필요한 열량을 온도센서가 자동으로 감지하여 필요한 열량만을 신속하게 공급하여 필요이상의 열량에 의한 부품파손이나 PCB손상이 없다. 또한, 고주파 유도가열에 의한 신속한 열량전달로 무연납의 이용(용융점 300°C이상)으로 환경의 유해한 요소가 전혀없다.The system constituted by the present invention operates by inducing high frequency induction heating of the iron tip by flowing a high frequency current generated at the high frequency generator by a temperature sensor to the high frequency coil of the iron body. In other words, the temperature sensor automatically detects the required amount of heat at the soldered part and supplies only the required amount of heat quickly so that there is no component damage or PCB damage caused by more than necessary amount of heat. In addition, the use of lead-free lead (melting point of 300 ° C or more) by rapid heat transfer by high frequency induction heating, there is no harmful element of the environment.

제1도는 본 발명에서 구성된 시스템의 구성도1 is a block diagram of a system configured in the present invention

제2도는 고주파 코일이 감긴 인두 바디와 인두 팁2 shows the iron body and the iron tip wound with high frequency coil

제3도는 직접 가열 방식과 고주파 유도 가열방식의 시간과 온도 특성3 shows time and temperature characteristics of direct heating and high frequency induction heating.

본 발명의 구성은 제 1도에 나타난 바와 같이 직류 전원(1) 50V에 의해 발진되는 고주파 발진기(2)에서 고주파 전류가 발생되고, 발생된 고주파 전류는 파워 앰프(3)를 통해 증폭된다. 그리고, 인두 바디(10)에 있는 코일(4)에 전류가 흐름으로써 인두 바디(10)에는 고주파 유도에 의한 열이 생긴다. 이 열은 인두 바디(10)를 가열하게 되고 이 열은 다시 인두 팁(5)을 가열하게 된다. 온도 조절부(6)는 직류 20V의 전원(1)을 사용한다. 온도 제어 방식은 인두 바디(10)에 부착된 온도 센서(8)의 전기적 신호를 증폭(7)한 후 비교기(9)에서 설정 온도와 비교하여 고주파 발진기(2)에서 만들어진 고주파 전류를 고주파 코일(4)로 흐르는 전류를 제어 (8)함으로써 온도 조절을 하게 된다.In the configuration of the present invention, as shown in FIG. 1, a high frequency current is generated in the high frequency oscillator 2 oscillated by the DC power supply 1 50V, and the generated high frequency current is amplified by the power amplifier 3. The current flows through the coil 4 in the iron body 10, and heat is generated in the iron body 10 by high frequency induction. This heat heats the iron body 10, which in turn heats the iron tip 5. The temperature control part 6 uses the power supply 1 of DC 20V. The temperature control method amplifies (7) the electrical signal of the temperature sensor (8) attached to the iron body (10) and compares the high frequency current produced by the high frequency oscillator (2) with the set temperature in the comparator (9). Temperature is controlled by controlling the current flowing in 4).

제 2도는 센서와 고주파 유도 가열에 의한 열량 전달 방법을 나타낸 것이다. 제 1도에서 설명한 고주파 발진기(2)에서 고주파 전류가 발생된 전류가 인두 바디(10)에 있는 코일(4)에 전류가 흐른다. 고주파 유도에 의한 열이 인두 팁(5)으로 직접 전달되고, 이 열량의 높고 낮음을 인두 팁(5) 끝에 내장된 온도 센서(8)에 의해 감지되고 이 신호는 제 1도의 비교기(9)에의해 조절된다. 특히, 여기서 사용되는 인두 바디(10)는 특수 재질로 만든 재료가 아니라 일반적인 금속체로서 충격이나 산화에 관계없이 신속하고 안전하게 열량을 인두 팁(5)에 전달 할 수 있다. 특히, 기존의 세라믹 인두기는 온도센서를 히터(인두 바디에 설치)에 연결하여 사용한 반면에 인두 바디(10)와 인두 팁(5) 사이의 온도차가 많이 생겨 온도 조절에 문제가 많았다. 본 발명은 인두 바디(10)가 아닌 인두 팁(5) 자체에 센서를 연결함으로써 정확한 온도의 측정과 제어를 할 수 있다.2 shows a heat transfer method using a sensor and high frequency induction heating. In the high frequency oscillator 2 described with reference to FIG. 1, a current flows through the coil 4 in the iron body 10. Heat from high-frequency induction is transferred directly to the tip of the pharynx (5), and the high and low amounts of this heat are sensed by a temperature sensor (8) built into the tip of the pharynx tip (5) and this signal is transmitted to Is adjusted. In particular, the iron body 10 used here is not a material made of a special material, but a general metal body, which can quickly and safely transfer calories to the iron tip 5 regardless of impact or oxidation. In particular, the conventional ceramic iron was used to connect the temperature sensor to the heater (installed on the iron body), while the temperature difference between the iron body 10 and the iron tip 5 was a lot of problems in temperature control. The present invention can measure and control the accurate temperature by connecting the sensor to the iron tip 5 itself rather than the iron body 10.

제 3도는 세라믹 인두기와 고주파 발열 인두기의 온도와 시간 특성을 나타낸 것이다. 세라믹 인두기(11)의 경우 납땜 할 때 인두의 최저온도(202°C)와 온도 회복 지연시간으로 인해 냉땜이 발생한다. 반면에, 고주파 발열 인두기(12)는 최저 온도(312°C)가 납을 충분히 녹일 수 있는 온도를 유지하고 온도 회복 시간이 2∼ 3(sec)이기 때문에 최적의 납땜 상태를 유지하는 것을 확인 할 수 있다. 제3 도는 각 인두의 온도를 320(°C)로 설정한 다음 300(mm) 길이의 납을 동판에 녹이면서 측정한 결과이다.3 shows the temperature and time characteristics of the ceramic iron and the high frequency heating iron. In the case of the ceramic iron 11, cold soldering occurs due to the minimum temperature of the iron (202 ° C) and the temperature recovery delay time when soldering. On the other hand, the high-frequency heating iron 12 maintains the optimum soldering state because the lowest temperature (312 ° C) maintains the temperature enough to melt the lead and the temperature recovery time is 2 to 3 (sec). Can be. 3 is the result of measuring the temperature of each iron by setting the temperature to 320 (° C) and then melting 300 (mm) long lead on the copper plate.

본 발명에 따르면, 종전의 방식의 온도 보상시간, 냉납 및 과열로 인한 PCB손상, 부품파괴등의 문제점 및 납땜 접합강도의 개선의 효과를 얻을수 있으며, 또한, 최근에 외국에서 보급되어 사용되고 있는 인공지능형 고주파 발열 인두 조절기의 카트리지의 충격에 약한 문제점과 교환방식에 의한 고가 비용의 문제점을 센서 내장형의 고주파 발열 인두기를 국산화하여 개발함으로써 수입 대체효과 및 환경 문제와 관련된 납의 사용 대체품으로 무연납의 사용에 큰 공헌을 할것으로 기대 된다.According to the present invention, it is possible to obtain the effects of the temperature compensation time of the conventional system, problems such as PCB damage, component breakdown due to cold soldering and overheating, and improvement of solder joint strength, and artificial intelligence type which has been widely used in foreign countries recently. By developing localized high frequency heating iron with built-in sensor, the weak problem of impact of cartridge of high frequency heating iron controller and the high cost by exchange method contributes greatly to the use of lead-free as a substitute for imported replacement effect and environmental issues. It is expected to do.
