[0031] The working principle is as follows: The battery cell 9 is transported by the conveyor belt 7. When it is in the transfer area, the clamping mechanism is controlled by the first position cylinder 29 to clamp the top of the battery cell 9. Specifically, the clamping control motor 31 works to make the clamping turntable 33 rotate. Under the connection of the connecting rod 34, the clamping rod 35 slides and performs the clamping operation. Further, the first position cylinder 29 controls the height of the battery cell 9. Then, the first transfer motor 23 works, and the second lead screw 24 and the second guide rod 25 move, that is, the first mounting seat 2501 and the second guide rod 25 move, and the battery cell 9 is transferred to the inside of the mounting box 6. By the work of the first lead screw motor 20, the first lead screw 21 rotates, and the first sliding seat 22 slides to adjust the position. The battery cell 9 is placed in the support cylinder 603 in the mounting box 6. Before placing the battery cell 9, the connecting frame 27 and the first cleaning adsorption part 28 can be controlled to move by the first cleaning control cylinder 26, and the bottom end of the battery cell 9 is cleaned by the first cleaning adsorption part 28, that is, impurities are adsorbed and removed, which is convenient for subsequent electrode connection.

[0032] When transferring the electrode connecting piece, the screw rod motor two 37 works, the screw rod three 38 rotates, and the slide seat two 39 moves to adjust the position. The transfer motor two 40 works, and the screw rod four 41 and the guide rod four 42 move, that is, the mounting seat two 4201 and the position cylinder two 44 move. The position cylinder two 44 adjusts the height of the adsorption part 45, and the electrode connecting piece is adsorbed and fixed by the adsorption part 45. The electrode connecting piece is pre-installed in the preparation box 46. The support motor 47 can work, the support screw rod 48 rotates, and the support table 49 moves to lift the electrode connecting piece. It should be noted that the electrode connecting piece is installed on the connecting groove 602, and the electrode connecting piece is located at the bottom end of the battery cell 9. The installation of the electrode connecting piece needs to be carried out first, and then the battery cell 9 is installed. Then, the battery cells 9 in pairs are welded by the welding mechanism.

[0033] Before the electrode connecting piece is adsorbed and fixed, the position of the rotation motor 51 can be controlled by the cleaning control cylinder two 50. The rotation motor 51 can adjust the orientation of the telescopic cylinder 52. The upper surface of the electrode connecting piece is cleaned of impurities by the cleaning adsorption part two 53. After the adsorption part 45 adsorbs the electrode connecting piece, the cleaning adsorption part two 53 removes impurities from the lower surface of the electrode connecting piece, and finally the installation is carried out.

[0034] During the welding process, the transfer belt one 11 is driven to move by the motor two 12, and the transfer belt two 13 is driven to move by the motor three 14.
