Automatic butt -welding machine

The utility model relates to an automatic butt -welding machine, include: frame, plummer, horizontal movement mechanisms, spot welding institution and feeding mechanism, horizontal movement mechanismsset up in the frame, and the drive of plummer and horizontal movement mechanisms is connected, and the plummer moves about down in the horizontal movement mechanisms drive and sets up in the frame, the relative plummer setting of spot welding institution, and spot welding institution sets up in plummer horizontal movement mechanisms's one side dorsad, and feeding mechanism sets up in the spot welding institution on one side of. The battery is placed on the plummer, and feeding mechanism carries the nickel strap to the spot welding institution by, spot welding institution with a butt welding of nickel strap on a battery, feeding mechanism cuts off the nickel strap, the motion of horizontal drive mechanism drive plummer for the welding of two batteries on spot welding institution other endwelding to another battery
