After the installation is completed, the fourth manipulator 20 is reset;

[0024] 5) Turn over the upper hard panel

[0025] When the upper hard panel 17 passes the end of the fifth roller table 22, the fifth photoelectric switch 24 at the lower rear of the fifth roller table 22 receives a signal, and the fifth manipulator 23 is activated to flip the upper hard panel 17 and transfer it to the sixth roller table 25. After the action is completed, the fifth manipulator 23 is reset;

[0026] When the upper hard panel is turned over, the fourth roller table 19, the fifth roller table 22, the first roller table 3, and the second roller table 7 operate synchronously;

[0027] 6) Casting combination material

[0033] 9) Plate cutting

[0034] When the composite board out of the laminator 28 passes the end of the eighth roller table 30, the second inductive grounding switch 32 at the lower rear of the eighth roller table 30 receives the aluminum foil signal attached to the front of the lower hard panel 1, and starts the pressing plate 31 to fall and press the upper hard panel 17.

[0035] 10) Tongue and groove processing on the remaining two sides of the composite board

[0036] The double-hard-surface pipe-added tube rigid polyurethane composite board 35 with tongue-and-groove on both sides enters the first acceleration roller table 34 and the second acceleration roller table 36. When the double-hard-surface pipe-added tube rigid polyurethane composite board 35 with tongue-and-groove on both sides touches the second travel switch 38 behind the second acceleration roller table 36, the second acceleration roller table 36 stops running.

The running speed of the third roller table 11 is greater than that of the first roller table 3 and the second roller table 7, so as to achieve seamless connection of the lower hard panel 1 on the seventh roller table 15;

[0064] 4) Install the positioning plug

[0065] When the upper hard panel 17 runs to the end of the fourth roller table 19, the fourth photoelectric switch 21 at the rear lower part of the fourth roller table 19 receives a signal, and the fourth manipulator 20 is started to install the positioning plug 18 on the upper hard panel 17. After the installation is completed, the fourth manipulator 20 is reset;

[0066] 5) Turn over the upper hard panel

[0076] 9) Plate cutting

[0077] When the composite board exits the laminator 28 and passes through the end of the eighth roller table 30, the second inductive grounding switch 32 below and behind the eighth roller table 30 receives the aluminum foil signal pasted in front of the lower hard panel 1, starts the pressure plate 31 to fall and press the upper hard panel 17, and at the same time the cross-cut saw 33 operates to cut between adjacent two hard panels, making a double-hard-face plus wire tube rigid polyurethane foam composite board 35 with rabbets on both sides.
