Research on a new type of soldering iron with automatic tin removal and smoke removal
1.1 Introduction to the structure of electric soldering iron
It is mainly composed of two parts: automatic tin outlet and smoke removal device.
(1) The automatic tin discharge part is composed of five parts: touch power-on device, high-temperature melting solder device, adjustable tin gun temperature device, automatic solder transfer device and automatic power-off device. Among them, temperature sensors, pressure sensors, etc. are used. The touch power-on device is manually triggered. When the human hand touches the temperature sensor and pressure sensor module, the power supply is automatically turned on and the electric soldering iron is heated. The high-temperature melting soldering device can heat up quickly when the power is turned on, so that the manual waiting time is shortened. The automatic power-off device works when the electric soldering iron is not in use, which can not only ensure the saving of electric energy, but also avoid danger when people are not around.
(2) The smoke removal device consists of a smoke duct, a smoking device and a smoke filter. The position of the pipe head can be adjusted freely according to the needs of the flue gas duct, which ensures the dynamic welding needs. When smoking, a vacuum environment is formed inside the device, and then the valve is opened to suck away the smoke generated during spot welding.
1.2 Introduction to the structure of the automatic tin output part
The automatic tin outlet part consists of a touch power-on device, a high-temperature melting solder device, and an adjustable
The tin gun temperature device, the automatic solder transfer device and the automatic power-off device are composed of five parts.
1.2.1 Touch Power Device
The pressure sensor and temperature sensor are applied, which are manually triggered. When the human hand touches the temperature sensor and pressure sensor module, the power supply is automatically turned on to heat the electric soldering iron.
1.2.2 High temperature melting soldering device
The high-temperature melting solder device uses electric heating wire to melt the solder, which can be heated rapidly when the power is turned on, so that the manual waiting time is shortened and the use efficiency is improved.
1.2.3 Adjustable tin gun temperature device
According to the thickness of the solder wire, the adjustable resistance is used to control the current of the heating wire by adjusting the size of the resistance, and then control the power of the heating wire to achieve the purpose of temperature adjustment.
1.2.4 Automatic solder transfer device
A micro motor is added to the welding torch, and a small gear is added to the motor to transmit the tin wire to the front end of the welding torch.
1.2.5 Automatic power-off device
The automatic power-off device combines temperature and pressure sensors, and it works after two minutes of non-use, which can not only ensure energy saving, but also avoid danger after people leave.
1.3 Introduction to the structure of the smoke removal part
It is composed of three parts: flue gas duct, smoking device, and flue gas filtering device.
1.3.1 Flue gas duct
Including the snake skin tube and the tube head, the tube head is in the shape of an inverted funnel, which can increase the effective area for absorbing smoke; the application of the snake skin tube can adjust the direction of the tube head arbitrarily, which meets the needs of dynamic welding.
1.3.2 Smoking devices
Use the motor and exhaust fan to suck the generated smoke into the filter device.
1.3.3 Flue gas filter
The filter element uses highly absorbent activated carbon and sponge as filter materials to effectively filter harmful gases.
2 Intelligent soldering iron materials for tin removal and smoke removal
2.1 Soldering iron
The handheld part is mainly made of plastic, which can reduce the weight of the electric soldering iron. The front end of the soldering iron is made of aluminum alloy, which can withstand high temperature and reduce the weight.
2.2 Temperature adjustment device, motor part and flue gas filtering combination part
Combine these three parts in the same aluminum alloy case with a thickness of 1mm.
2.3 Snake tube
It is made of 301 stainless steel and 304 stainless steel, and the outer layer is coated with wax oil, which can improve the sealing performance, mainly to ensure that the direction of the smoking port can be changed at will, and can also play the role of fixing the smoking port.
2.4 Flue gas filter
Including filter element, motor, exhaust fan.
2.4.1 Filter element
The compressed activated carbon filter element uses activated carbon and sponge with high adsorption value as the filter material, and is compressed into a food-grade adhesive. The inside and outside of the filter element are respectively wrapped with non-woven fabrics with filtering effect to ensure that the carbon element itself will not drop activated carbon powder. Rubber gaskets are installed at both ends of the carbon element to make the compressed carbon element fit into the filter cartridge and have a good seal. sex.
2.4.3 Exhaust fan
Combined with the motor, it mainly plays the role of smoking.
