9. A method for using a lithium battery pack processing and assembly machine, characterized in that: S1: First, the lithium battery base plate (14) is placed on the clamping platform (23) from directly above the clamping platform (23). When the lithium battery base plate (14) contacts the four contactors (210), the electric telescopic rod (211) is activated to extend and retract downward, thereby driving the toothed plate (29) to slide downward on the inner side of the clamping platform (23), thereby driving the gear (28) to rotate, thereby driving the screw rod (27) to move in the slide groove (25). The inner side of the clamping platform (23) is rotated, thereby driving the slider (26) to slide on the inner side of the slide groove (25), thereby driving the two sets of slide plates (212) on the upper surface of the clamping platform (23) to slide in a direction close to each other, thereby clamping and fixing the lithium battery bottom plate (14) above the clamping platform (23), thereby fixing the position of the lithium battery bottom plate (14), and then transmitting the clamping platform (23) to the position where the lithium battery group is installed through the transmission of the conveyor belt (12), so as to facilitate subsequent installation; S2: Secondly, by starting the motor 1 (36), the output shaft of the motor 1 (36) drives the adjustment block (31) to rotate, thereby driving the connection plate (311) to rotate, and rotating the connection plate (311) to the lithium battery pack area, and then by starting the motor 2 (38) and the dual-axis motor (310), the position of the connection arm (39) and the connection plate (311) can be adjusted, so that the connection plate (311) is directly facing the lithium battery pack; S3: Finally, by starting the motor three (314), the output shaft of the motor three (314) drives the bidirectional screw rod (315) to rotate, so that the slider two (317) slides relatively on the inner side of the slide groove two (316), thereby driving the two groups of clamping plates (318) to slide in a direction close to each other, so that the lithium battery pack is clamped between the two groups of clamping plates (318), and then by starting the motor one (36), the output shaft of the motor one (36) drives the connecting plate (311) to reset, and then through the transmission of the transmission belt (12), at the same time, on the guide rod ( Under the guiding action of the conveyor belt (21), the moving position of the clamping platform (23) on the conveyor belt (12) will not be offset, so that the clamping platform (23) can be stably transferred to the position directly below the connecting plate (311), and then by starting the cylinder (3), the output shaft of the cylinder (3) drives the adjusting block (31) to move downward, so that the connecting plate (311) is synchronously lowered, so that the four groups of docking rods (24) are inserted into the inner side of the four groups of docking grooves (313), so that the lithium battery pack is docked with the lithium battery bottom plate (14), thereby completing the assembly of the lithium battery pack.
