The boss (719) of the fourth synchronous belt (718) pushes the side (73) to the side welding assembly (8). The fifth synchronous pulley (717) and the worm gear (714) are installed at both ends of the first connecting shaft (715). The first connecting shaft (715) is installed on the base (10) through the second support seat (716). The worm (712) meshes with the worm gear (714) for transmission. The worm (712) is installed on the base (10) through the first support seat (713). The fourth synchronous pulley (711) is mounted on the worm gear (712). The fourth synchronous pulley (711) is connected to the third synchronous pulley via the third synchronous belt (710). The third synchronous pulley is fixed coaxially with the grooved wheel (78). The wheel finger (76) is fixed on the dial wheel (75). The grooved wheel (78) is provided with multiple slots (79). The dial wheel (75) drives the wheel finger (76) to be placed into the slots (79) of the grooved wheel (78). Thus, the dial wheel (75) drives the grooved wheel (78) to move intermittently. The main shaft of the torque motor (52) passes through the rotary table mounting bracket (51) and is connected to the dial wheel (75). The side welding assembly (8) includes a clamping cylinder (81), a pressure plate (82), and a welding gun (83). The pressure plate (82) is mounted on the clamping cylinder (81), and the welding gun (83) is mounted on the pressure plate (82). The clamping cylinder (81) drives the pressure plate (82) to press the side against the side of the stacked end plate (1), battery cell (2), and insulation plate (3). The welding gun (83) welds the side (73) to the end plate (1).

2. The lithium battery production system according to claim 1, characterized in that: The baffle (9) is provided with several U-shaped slots. The U-shaped slots are larger than the diameter of the drag column (511), and the spacing between the U-shaped slots is the same as the spacing between the drag column (511).
