The working principle of the utility model is as follows: the gluey core board of taking that the spreading machine came out carries through conveying mechanism A1 to first panel wainscot mechanism A and carries out the top surface wainscot, later get into turnover panel frame B2 through conveying mechanism A1 on the foldable turnover mechanism B and carry out the turnover, then carry and carry out the back wainscot to second panel wainscot mechanism C, panel behind the wainscot carries out sign indicating number board mechanism D and falls into sign indicating number grillage after carrying out position adjustment, treat on the sign indicating number grillage behind the panel of accumulation take the altitude, it shifts to next process through fork truck.

During operation, the lifting mechanism A4.1 of the panel storage station A4 on the two sides of the conveying mechanism A1 is respectively provided with a panel to be veneered, and in order to improve the working efficiency and the veneering precision, the front end of the panel is aligned with the limiting plate A1.13 in the vertical direction. Starting a first power mechanism A2.6, the first power mechanism A2.6 drives two groups of panel adsorption mechanisms A3 to move to one side of a first conveyor A1 at the same time, when a proximity switch A2.9 touches the edge of a panel to be veneered, under the action of a delay relay, a telescopic cylinder A3.20 drives a top fine adjustment frame A3.3 and a middle adsorption frame A3.2 to descend, so that the suction disc A3.9 adsorbs the panel to be veneered through negative pressure, under the action of the delay relay, the telescopic cylinder A3.20 drives the top fine adjustment frame A3.3 and the middle adsorption frame A3.2 to ascend, in the process, a third induction switch A3.4 detects whether the panel is adsorbed all the time, and if the third induction switch A3.4 does not detect the panel, the telescopic cylinder A3.20 acts again to perform panel adsorption operation.

In the process, if the proximity switch A2.9 is not aligned with the edge of the panel, the fine adjustment motor A3.14 controls the rotary screw A3.13 and the rotary screw seat A3.17 to enable the middle adsorption frame A3.2 to carry out left and right fine adjustment, so that the veneering precision is ensured.

After the panel is detected by the third inductive switch A3.4, the first power mechanism A2.6 is started to rotate reversely under the action of the delay relay, and the first power mechanism A2.6 drives the first inductive switch to contact with the end part of the limiting frame A3.18, so that the first inductive switch stops rotating, at the moment, the panel adsorption mechanism A3 adsorbing the panel is arranged outside the position right above the first conveyor A1, and the panel is waited at the position.

And (2) starting a second power mechanism A1.5 on the first conveyor A1, driving the transmission rod A1.2 and the conical roller A1.3 to rotate by the second power mechanism A1.5, driving the core plate coated by the coating machine, namely the core plate with the glue, to the lower part of the frame A2 through the conical roller A1.3, starting the limiting expansion device A1.14 after the front end of the core plate with the glue approaches the longitudinal limiting mechanism by the second induction switch and sensing the core plate with the glue, driving the limiting plate A1.13 to extend out by the limiting expansion device A1.14, blocking the core plate with the glue from further advancing, and thus, achieving the longitudinal limiting effect.
