[0027] When the processed battery cell needs to be flipped, the flipping clamp cylinder H7 clamps the processed battery cell on the flipping battery cell slot H8 to ensure that it is firmly fixed; then, the rotating cylinder H6 is controlled to rotate, thereby driving the flipping clamp cylinder H7 connected to its rotating shaft to rotate; since the processed battery cell is clamped in the flipping clamp cylinder H7, as the rotation action proceeds, the processed battery cell will also be flipped to the required position; once the flipping is completed, the flipping clamp cylinder H7 releases the clamping of the processed battery cell to complete the flipping operation.

[0028] Furthermore, a slide rail cylinder H9 is vertically arranged between the rotating cylinder H6 and the flipping frame H4; and the slide rail end of the slide rail cylinder H9 is fixedly connected to the back of the rotating cylinder H6, and the back of the slide rail cylinder H9 is fixedly connected to the flipping frame H4; and when the piston rod of the slide rail cylinder H9 is extended and retracted, the slide rail end is driven to move up and down, thereby synchronously driving the rotating cylinder H6 to move up and down.

[0034] Specifically, the push cylinder H14 is located on the positioning table H10 and is used to provide a push force; the push cylinder H14 can extend or retract a piston rod by controlling air pressure; the piston rod of the push cylinder H14 is connected to a push rod H15; a push protrusion H16 is formed at the other end of the push rod H15, and the number of the push protrusions H16 corresponds to the number of the positioning battery cell slots H11; a push protrusion H16 is formed at the other end of the push rod H15 and is used to push and position the processed battery cell in the length direction; the number of the push protrusions H16 should correspond to the number of the positioning battery cell slots H11 to ensure that each processed battery cell can be accurately positioned;
