When the vanadium liquid flow battery stack 10 needs to be aligned, the motor 1 306 is driven and the pay-off wheel 408 can release the pull rope 409 when the motor 1 306 is working. At this time, the slider 1 403 and the slider 2 406 are popped out by the compression spring 1 402 and the compression spring 2 405, so that the shell 2 404 and the protruding rod 407 extend and move toward the vanadium liquid flow battery stack 10, thereby completing the alignment work. At the same time, after the alignment is completed, the motor 1 306 is driven to work in the reverse direction to make the pay-off wheel 408 reel in the pull rope 409, thereby retracting the protruding rod 407 and the shell 2 404, thereby reducing the impact on welding.

[0052] Secondly, after the upper part is welded, the two screw rods 603 are driven by the bidirectional motor 602 to drive the two nut seats 604 and the connecting plate 301 to approach each other, so that the two storage plates 204 can be brought close to each other, thereby completing the clamping of the vanadium liquid flow battery stack 10. At the same time, the motor 1 306 is driven to complete the positioning of the vanadium liquid flow battery stack 10. At this time, the motor 2 701 is driven to make the gear 702 drive the outer gear ring 703 and the disc 601 to rotate, so that the clamped vanadium liquid flow battery stack 10 can be flipped.
