6-3, driving a lifting device and a rotating device to drive a flexible butt joint turnover device and a multifunctional flexible positioning tool to rotate to 0 degree, namely, enabling the installation surfaces of the T-shaped stringer and the stringer forming die on the multifunctional flexible positioning tool to face upwards and the multifunctional flexible positioning tool to descend to the lowest position, so that the T-shaped stringer and the stringer forming die can be conveniently installed on the upper frame;
6-4, sequentially placing a plurality of different T-shaped stringers and stringer forming dies on the multifunctional flexible positioning tool by using a crane in the frame, positioning, fixing and pressing each T-shaped stringer and stringer forming die, and splicing the T-shaped stringers and stringer forming dies into a whole;
6-5, driving a lifting device and a rotating device to drive a flexible butt joint overturning device, a multifunctional flexible positioning tool and a T-shaped stringer and stringer forming die to ascend to a certain height, rotating the flexible butt joint overturning device, the multifunctional flexible positioning tool and the T-shaped stringer and stringer forming die 180 degrees to enable the installation surface of the T-shaped stringer and stringer forming die to be downward, and then moving the flexible butt joint overturning device, the multifunctional flexible positioning tool and the T-shaped stringer and stringer forming die downward to a butt joint position;
6-6, transporting the corresponding skin and the skin forming die to a butt joint position under the multifunctional flexible positioning tool through an AGV (automatic guided vehicle), and withdrawing the AGV;
6-7, releasing the V-shaped locking device, and enabling the flexible butt joint turnover device and the multifunctional flexible positioning tool to be connected only through a sling mechanism, so that the inner frame and the multifunctional flexible positioning tool inside the inner frame are in a hoisting floating state; the lifting device moves to drive the inner frame and the multifunctional flexible positioning tool to move downwards, and the positioning device on the multifunctional flexible positioning tool is accurately matched with the positioning cone and the positioning flat cone on the skin forming die, so that the T-shaped stringer is accurately butted with the skin.
