The flexible grasp of automatic welding technology is very important for the production of electronic products such as integrated circuit board, and the most critical step is to accurately control the temperature of the welding area. This paper will establish the mechanism model of the influence of the temperature of each temperature zone of the reflow furnace and the speed of the conveyor belt on the temperature of the welding area through the relevant thermodynamic theory, so as to help the relevant electronic product manufacturers to accurately control the temperature of the welding area. The mechanism model of temperature change in the center of welding area is established, and the heat transfer process is divided into three steps. Firstly, according to the temperature field of the air in the furnace, the air temperature corresponding to the gap in the small temperature zone is determined, and then the heat convection process between the air temperature in the furnace and the surface of the welding area is described by using Newton’s cooling law. Finally, Fourier law is used to study the heat conduction process in the welding area.
