Abstract

The application discloses a power battery dynamic assembling system and a dynamic assembling method. The assembling system comprises a main conveying line, a shell-entering conveying line and a welding conveying line. The main conveying line and the shell-entering conveying line are parallel to each other, and the shell-entering section exists between the main conveying line and the shell-entering conveying line. The transport carrier and the shell-entering tool enter the shell-entering section at the same speed and in the same direction. The main conveying line and the welding conveying line are parallel to each other, and the welding section exists between the main conveying line and the welding conveying line. The transport carrier and the welding tool enter the welding section at the same speed and in the same direction. The transport carrier keeps the same speed with the shell-entering tool in the shell-entering section, so that the shell-entering tool is relatively static with the battery cell, and the shell-entering action is facilitated. Meanwhile, the transport carrier keeps the same speed with the welding tool in the welding section, so that the battery cell keeps the same speed with the welding tool, and the clamping positioning and the protection cover are facilitated, the welding is smoothly carried out, and the battery cell keeps the movement state in the shell-entering and welding, the whole production line is dynamic, and the processing and circulation efficiency is high.
