The cylindrical batteries are automatically driven toward each device by the first reflux fixture device 2. When the cylindrical batteries are transferred to the positions of a plurality of assembly devices 4, the pole and cover plate components are assembled by the assembly devices 4. The cover plate components include an upper insulating sheet, a seal and a lower insulating sheet. The pole and cover plate components are then transported to a detection device 5 for detection, thereby ensuring the accuracy of the assembly position of the pole and cover plate components. After the detection, the cylindrical batteries are transported to a pre-riveting assembly device 5. At the position of position 6, the pre-riveting device 6 preliminarily connects the pole and the cover assembly with the cylindrical battery, and then the pre-riveted surface of the cylindrical battery is dumped through the cleaning device 7; the cylindrical battery is transferred to the second reflux fixture device 3 through the transfer device 8, and then flows into the riveting device 9, which presses the pole with the cover assembly and the cylindrical battery to form a strong electrical and mechanical connection. The cylindrical battery after riveting is transported to the cleaning device 10 for cleaning, which helps to improve the reliability and service life of the battery. Finally, the cylindrical battery is unloaded through the unloading device 11.
