and S4, pre-pressing the glued raw materials through a pre-pressing assembly (600) to obtain a pressed product, transferring the pressed product into a stacking preparation roller way (700), and transferring the pressed product onto a rolling line (900) through a truss manipulator (800) to wait for further processing after the pressed product is on the stacking preparation roller way (700).

9. The intelligent glue spraying method for the cryogenic composite thermal insulation material, which is disclosed in claim 8, is characterized in that the raw material centering positioning process in the step S1 is as follows:

Step S11, after the raw materials are placed on the placing table (402), a servo motor (403 c) is started to drive a bidirectional screw rod (403 b) to rotate, and a positioning block (403 d) is driven to approach each other, namely a stop lever (403 e) moves into a U-shaped hole (402 c);

And step S12, when the stop lever (403 e) moves in the U-shaped hole (402 c), pushing force is applied to the raw material placed on the placing table (402) so that the raw material moves to a preset position of the placing table (402) to be centered.

10. The intelligent glue spraying method for the cryogenic composite thermal insulation material according to claim 8, wherein the pre-pressing treatment process in the step S4 is as follows:

s41, when the conveying plate of the pre-pressing assembly (600) receives the raw materials subjected to glue spraying, the conveying plate is 15-20mm higher than the platform surface, and the conveying plate is in butt joint with the transition roller way (500) in a same-speed ratio;

Step S42, when the raw materials subjected to glue spraying move to a conveying plate and move to a set position, the conveying plate is lowered to 5-20mm below a workbench surface, and the upper workbench surface is lowered to the upper surface of an insulating box product at a constant speed and then is pressurized, so that pressure maintaining work is performed;

And S43, after the dwell time reaches a set value, the upper working platform surface is quickly lifted in place, the lower platform plate chain is simultaneously lifted in place, a pressed product is obtained, and the pressed product is conveyed to a rolling line (900).
