The invention relates to the field of high-frequency soldering, in particular to a high-frequency induction soldering machine. The high-frequency induction soldering machine comprises a shell, wherein a touch screen is arranged on the front side wall of the shell. The shell is internally provided with a main loop and a control loop. The main loop comprises two three-phase electric reactors, two rectification bridges, two IGBTs and high-frequency transformers. The two three-phase electric reactors connected with a power source through switches are connected with the two rectification bridges respectively, the two IGBTs are connected with the two transformers respectively, and the two transformers are connected with two output ends respectively. The control loop comprises a PLC which is connected with the touch screen, a water cooling system and the three-phase electric reactors, the rectification bridges and the IGBTs in the main loop. Full automatic control over the high-frequency induction soldering machine is achieved, and the working efficiency and manufacturing precision are high.
Description
technical field [0001] The invention relates to the field of high-frequency brazing, in particular to a high-frequency induction brazing machine. Background technique [0002] The high-frequency brazing machine is an induction heating device that heats the solder to a certain temperature through an induction current to melt the solder, thereby connecting two metals of the same material or different materials. The brazing process of the high-frequency brazing machine: the surface-cleaned workpieces are assembled together in an overlapping manner, and the solder is placed near the joint gap or between the joint gaps. When the workpiece and the solder are heated to a temperature slightly higher than the melting point of the solder, the solder melts (the workpiece is not melted), and is sucked into the gap between the solid workpiece by capillary action, and the liquid solder and the metal of the workpiece diffuse and dissolve. After cooling, a brazed joint is formed. [0003]...
