Therefore, the establishment of the sound barrier panel to solve the traffic noise pollution becomes a main mode of urban road noise control.

At present, sound insulation barrier panels are mainly classified into two major types, namely metal sound barrier panels and non-metal sound barrier panels. The non-metal sound barrier board is mainly a concrete sound barrier board, is made of reinforcing steel bars, concrete and sound-absorbing cotton, and has the characteristics of good durability, strong deformation resistance, low manufacturing cost and the like. Because the concrete sound barrier plate has high transportation cost, construction enterprises generally adopt on-site manual production to reduce investment. At the present stage, after the sound barrier plates are manufactured, an operator usually adopts a manual stacking mode to stack the sound barrier plates, and the manual stacking mode is low in production efficiency, high in labor cost and low in automation degree, and cannot meet the requirement of large-batch application. In addition, because the concrete sound barrier panel is heavy, when the concrete sound barrier panel needs to be turned over and demoulded, the mould needs to be manually erected along the length direction at the moment, and the demoulding is carried out on the concrete sound barrier panel. Thus, the labor intensity of workers is high; in the demolding process, the concrete sound barrier plate is easy to tilt, and construction workers are injured by crashing, so that safety accidents are caused. Therefore, there is a need to develop a concrete sound barrier panel de-molding and stacking production line to solve the defects in the prior art.

(2) The overturning demolding mechanism clamps the mold table and the sound barrier plate by controlling the first oil cylinder and the second oil cylinder to act, and the motor drives the clamping part to rotate relative to the connecting end 231; thereby turning the sound barrier plate and the die table for 180 degrees, and enabling the end face of the sound barrier plate to face the conveying mesh belt of the first conveying mechanism; the sound barrier plate and the mould platform are placed on the first conveying mechanism through the sliding seat on the movable rack, the second oil cylinder returns at the moment, the end face of the sound barrier plate is in contact with the conveying net belt on the first conveying mechanism, the end face 102 of the sound barrier plate is in friction with the conveying net belt, and therefore the sound barrier plate 100 is separated from the mould platform 200, and the sound barrier plate is conveyed to the next station on the first conveying mechanism 3. And then controlling the sliding seat to move, and placing the die table 200 on the first conveying mechanism for conveying.

(3) Controlling an AGV navigation trolley, moving the stacker crane to a delivery area of the first conveying mechanism, and driving two clamping arms to clamp two sides of the sound screen baffle plate through a third oil cylinder; then controlling an AGV (automatic guided vehicle) to transport the sound barrier plates to a stacking station, controlling a lifting device to place the sound barrier plates at a proper height, driving a third oil cylinder to control two clamping arms to loosen the sound barrier plates, and placing the sound barrier plates at a receiving part (a delivery end) so as to repeatedly stack for multiple times;

(4) when the sound barrier plates are piled up into a preset number of small blocks, the sound barrier plates are packed with bag belts and then the bearing parts are driven by the first oil cylinders to rotate to one end of the fixing part to be matched with the fixing part in an abutting mode; the sound barrier plates which are originally horizontally stacked on the bearing parts are turned for 90 degrees, the vertically placed sound barrier plates are chopped, and a forklift is convenient to transport to a finished product stacking area. And the first oil cylinder returns to the position, and the bearing part is pulled back to the workbench again.
