The invention discloses a heating module of an MPY tin dipping machine. The heating module comprises a heating core fixing sleeve, a heating core, a tin feeding nozzle, an angle adjusting block, a guide track and a spring guide sleeve, wherein the heating core consists of a heating bar and a solder tip which are combined tightly, and is arranged on the heating core fixing sleeve; the solder tip and the heating bar are connected integrally; the heating core is inserted in the heating core fixing sleeve , and the heating core fixing sleeve and the angle adjusting block are locked on an angle adjusting block through screws; the angle adjusting block is arc-shaped, and is fixed on the guide track through screws; and the angle adjusting block is further connected with the spring guide sleeve. In the heating module of the MPY tin dipping machine, the solder tip and the heating bar are connected integrally, the area of the portion, which is in contact with the solder tip, of the heating bar is increased favorably, and thus, it can be ensured that the solder tip can be heated rapidly; and the angle adjusting block is connected with the spring guide sleeve, by the buffering effect of the spring guide sleeve, the heating core has a vertical buffering effect during welding, and collision to the heating core and a workpiece due to extrusion of the solder tip and the workpiece can be prevented effectively.
