The invention relates to full-automatic accessory spot welding equipment. The full-automatic accessory spot welding equipment comprises a main rack, a feeding assembly, a collection assembly, a paintbreaking assembly, a spot welding assembly, a repainting assembly and an accessory conveying assembly. The feeding assembly comprises a feeding conveying component, a feeding driving component and a discharge component. The paint breaking assembly, the spot welding assembly and the repainting assembly are arranged along the feeding conveying component in sequence. The accessory conveying assemblycomprises a first conveyor belt, a second conveyor belt, a conveyor belt driving component, a first accessory supply component and a second accessory supply component. The first accessory supply component and the second accessory supply component are arranged at the head ends of the first conveyor belt and the second conveyor belt correspondingly. The feeding conveying component is located at thetail ends of the first conveyor belt and the second conveyor belt. The full-automatic accessory spot welding equipment integrates the functions of automatic discharging, feeding, u-bolt feeding, carrying ring feeding, paint breaking, spot welding, repainting and material collecting. The operating radius of personnel is small. The full-automatic accessory spot welding equipment can be operated by asingle person who only needs to place and take materials, ensures the efficiency and safety, facilitates automatic management, reduces the defective rate of products and improves the yield, and the number of the personnel is reduced.
