The method of claim 1-8, wherein: The steps include: S1, bottle body placement Place the bottle body (3) to be capped or uncapped on the bottom plate (1), and at this time the bottle body (3) needs to ensure that it is in the middle position of the two positioning plates (63); S2, bottle body clamping First, the clamping mechanism (6) is controlled to clamp and position the bottle body (3), so as to avoid the movement of the bottle body (3) during capping or uncapping, which leads to the failure of capping or uncapping; S3, bottle body clamping The clamping plate (59) is controlled by rotating the assembly to adjust the direction of the clamping plate (59) to the position of the screw cap (4), and then the screwing mechanism (5) is controlled to lift to clamp the screw cap (4), and then the screwing operation is performed after clamping to realize the disassembly and assembly of the cap. If the cap is assembled, the screw cap (4) to be installed can be clamped and screwed on the bottle body (3) through the above steps. If the cap is disassembled, the screw cap (4) can be removed, and then the screw cap (4) screwed down is placed elsewhere through the above direction adjusting steps.
