Description

 Smart heat gun  

The invention relates to a smart heat gun.

In electronic products, if the chip components are to be soldered to or soldered off the circuit board, it is usually necessary to melt the solder through the heat gun to blow the chip components on the circuit board, or to solder them on the board. The solder material on the circuit board is melted to remove the chip component; wherein the chip component is, for example, a chip resistor, a chip capacitor, a chip inductor or a chip transistor.

The conventional hot air gun mainly comprises a gun body and a hot air nozzle electrically connected to the main body, the hot air nozzle is connected to one end of the gun body, and the hot air nozzle is provided with an air outlet at an end away from the gun body; when using, the gun body is first picked up. Align the hot air nozzle with the placed tin and patch components, set the heating temperature on the main machine, then start the gun body to generate hot air and let the hot air blow out from the hot air nozzle, so that the hot air is blown on the tin and the patch components through the hot air nozzle. Until the solder melts, the chip component is soldered to the circuit board; conversely, the solder material soldered on the circuit board can be melted by the hot air provided by the heat gun, and the chip component connected to the circuit board is connected. Removed.

However, in the case where the conventional heat gun is not in use, the user must cut off the power supply to the heat gun at the host, so that the heat gun stops outputting the hot air, but if the user forgets to cut off the power supply of the heat gun, the host is prone to occur. The accident of hot air blown by the hot air gun; in addition, when blowing or disassembling the chip components, the wind speed, wind temperature and wind direction of the hot air blown by the hot air nozzle need to be manually adjusted according to the user's experience, but if When the size of the chip component is too small, it is difficult for the user to observe the condition of the blow welding or the desoldering, and the wind speed, the air temperature and the wind direction of the appropriate hot air cannot be accurately adjusted, thereby causing the chip component to be easily welded or broken. In addition, in the process of blow welding or desoldering, tin gas is generated because the tin material needs to be melted. When the user sucks more tin gas, it is easy to cause tin poisoning, such as tin deposit. The symptoms of illness or breathing are difficult to overcome, and the shortcomings mentioned above are urgently needed to be improved.
