s2, enabling the intelligent adjusting tray bearing the bottom tray to enter a paper laying station, laying moistureproof paper and a lower paperboard on the bottom tray, conveying the bottom tray to a stacking station to place a stacked plate on the moistureproof paper, then laying the upper paperboard and the moistureproof paper on the upper surface of the stacked plate, folding and flattening four corners of the moistureproof paper, fixing the moistureproof paper by using an adhesive tape, and forming a cuboid plate stack structure with the stacked plate inside and the outer surface completely coated by the moistureproof paper;

s5, the intelligent adjusting tray loaded with the cuboid plate stack structure enters a transfer station, and the cuboid plate stack structure with the outer protection cover plate and the bottom tray are transferred away from the intelligent adjusting tray.

7. The packaging method as claimed in claim 6, wherein if it is required to stack the sheets with the bottom surfaces thereof facing upward, the step of turning over the structure of the rectangular parallelepiped stack is performed between step S2 and step S3 by:

8. The packaging method according to claim 6, wherein step S3 is as follows:

the manipulator is with the cooperation of intelligent tray with four perpendicular angle beads subsides at 4 perpendicular edges of cuboid sheet pile structure, and it is fixed to make a bundling belt afterwards.

9. The packaging method of claim 6, further comprising, prior to delivering the smart adjustment tray to the packaging track, the steps of: the intelligent adjusting tray is adjusted according to the specification data of the bottom tray, so that the intelligent adjusting tray is enclosed into an area corresponding to the specification of the bottom tray.
