The invention relates to the technical field of automatic
welding, in particular to a PCB power device automatic
welding device which comprises an automatic
welding machine, a bottom plate is fixedly connected to the lower end of the automatic welding
machine, a welding frame is fixedly connected to the lower end of the bottom plate, an electric
soldering iron is fixedly connected to the lower surface of the welding frame, and a fixing column is arranged below the bottom plate. According to the
tin feeding device, a small rotating rod can be driven to rotate through a rotating speed adjusting device and a motor in the
tin feeding device, then a large adjusting wheel and a small adjusting wheel are driven to rotate, accurate adjustment of the rotating speed of an inner rotating rod is achieved through matched use of a speed adjusting fork, the rotating speed of the inner rotating rod is adjusted, and the
tin feeding device is convenient to use. According to the design, the sending-out speed of the solder wire in the
welding process can be flexibly adjusted according to actual needs, so that the stability and the consistency of the welding quality are ensured, and the accurate control requirements under different welding requirements are met.
