Full-automatic tin discharging machine

The utility model provides a full-automatic tin discharging machine which comprises a mounting plate, one side of the mounting plate is fixedly connected with a tin feeding nozzle, the other side of the mounting plate is fixedly connected with a tin discharging nozzle, a driving assembly is mounted on the surface of the mounting plate, a tin feeding assembly is mounted on the driving assembly, and an electric soldering iron is connected with a GND of a control circuit. A tin wire is connected with an input pin of a single chip microcomputer or a controller through a spring or other conductive metal devices, the input pin is connected to a VCC through a 100K resistor or is made to be in a high level, at the moment, the level sampled by the input pin is the high level, and when the electric soldering iron makes contact with the tin wire, the level of the input pin is pulled to be in a low level; at the moment, the single-chip microcomputer controls the driving motor to start tin wire retraction and delayed tin
