When the third transverse driving mechanism 3-1 drives the second clamping mechanism to convey the end of the aluminum skin 6 to a position between the upper clamping block 9 and the lower clamping block 10 of the first clamping mechanism of the first clamping module 5-2, the clamping driving mechanism 11 of the first clamping mechanism of the first clamping module 5-2 drives the upper clamping block 9 and the lower clamping block 10 to move so as to clamp the aluminum skin 6, and the clamping cylinder 3-2 drives the upper clamping plate 3-3 and the lower clamping plate 3-4 to loosen the aluminum skin 6, so that the end of the aluminum skin 6 clamped by the second clamping mechanism in the transition clamping mechanism 3 is transferred to the first clamping module 5-2.
