Full-automatic duckbill welding device

The invention discloses a full-automatic duckbill welding device which comprises a rack, a belt feeding mechanism, a static duckbill feeding mechanism, a hinged catch feeding mechanism, a welding platform, a welding actuator, a discharging mechanism and an electric control unit; for feeding and discharging of a belt, a static duckbill and a hinged catch, a baffle is mechanically controlled to openand close, and attraction of an electromagnet is cooperated synchronously; before the static duckbill and the hinged catch are welded, the static duckbill and the hinged catch are located and fixed through the shapes of the discharging ends of a static duckbill storage chute and a hinged catch storage chute, two supporting plates are separated after completion of welding of the duckbill, and theduckbill falls onto a conveyor device under the gravity of the duckbill, and is conveyed to a finished product box; according to the scheme, only the belt, the static duckbill and the hinged catch need to be placed manually, s
