The invention discloses self-unloading spot welding equipment. The self-unloading spot welding equipment comprises a spot welding machine body, two supporting frames arranged on the left side and theright side of the spot welding machine body correspondingly, rollers arranged on the two supporting frames correspondingly, a track sleeving the part between the two rollers and penetrating through the spot welding machine body, a stepping motor arranged at the bottom of any supporting frame and connected with the roller on the supporting frame, and an unloading auxiliary structure arranged on theother supporting frame; and the track is formed by a plurality of track plates which are connected in series, and two clamping welding structures are further symmetrically arranged on each track plate. According to the self-unloading spot welding equipment, the spot welding efficiency can be well improved, the time required by feeding, discharging and positioning is greatly shortened, and thus development of an enterprise is promoted.
