An adsorption bracket is fixedly installed on the connecting rod, and the adsorption bracket reciprocates between the adsorption station and the stacking station. The adsorption bracket is provided with an adsorption structure for adsorbing the composite plate, and the conveying bracket is provided with an adsorption notch for avoiding the lifting of the adsorption bracket. The conveying bracket is provided with a limiting structure for limiting the position of the composite plate at the adsorption station; first, the conveying bracket conveys the produced composite plate to the adsorption station, with the front side of the composite plate with the protective film facing upwards, and then the limiting structure limits the position of the composite plate. The plate is limited to ensure the accuracy of the adsorption position, the lifting power device drives the lifting slide to descend, and the transverse power device drives the transverse slide bar to slide transversely so that the adsorption bracket is above the composite plate, and then it descends to adsorb through the adsorption structure, and then the adsorption bracket rises while the transverse slide bar continues to slide transversely, so that the adsorption bracket is on the stacking position, and then the adsorption structure is lowered to release the composite plate, so that the composite plate falls accurately on the stacking position, with the front of the composite plate facing up, and then the adsorption bracket rises back to the adsorption position, and then the rotating power device drives the adsorption bracket to flip upward, and then it descends and falls into the adsorption gap, and then the composite plate is stacked. The board continues to be transported, and the adsorption bracket moves upward to make the adsorption structure adsorb the composite board, and then after rising, the adsorption bracket is turned downward, so that the front side of the composite board faces downward, and then it is limited by the limiting structure, and adsorbed again, and moved to the stacking station, so that the front side of the composite board adsorbed this time is stacked with the front side of the composite board stacked last time, and the back side of the composite board faces upward, followed by the front side of the next composite board, so that the two back sides are stacked together to protect the front side of the composite board; the device can share a production line for the composite boards transported, and complete the stacking by effective adsorption and movement, thereby ensuring the stacking efficiency and reducing the use cost.

[0015] Furthermore, since the adsorption bracket is a rectangular frame, a frame cross bar fixedly connected to the connecting rod is provided in the middle of the rectangular frame, the adsorption structure is a plurality of adsorption suction cups, and the adsorption suction cups are vertically installed on the rectangular frame in sequence, and the adsorption suction cups are connected to a negative pressure exhaust system.

[0016] Because the lifting slide passes through the driving box body and slides up and down, a driving sprocket and a driven sprocket are rotatably installed on the top of the driving box body at both sides, and the lifting power device drives the driving sprocket to rotate, and one end of the chain is connected to the lifting slide, and the chain is wound around the driving sprocket and the driven sprocket, and the other end of the chain is connected to the counterweight slide, and the counterweight slide is lifted and slidably installed on the driving box body, and the lifting direction of the counterweight slide is opposite to that of the lifting slide; the chain cooperates with the driving sprocket and the driven sprocket, and the transmission is stable and reliable.

[0017] Furthermore, since the lifting power device includes a double-headed driving motor fixedly mounted on the top of the driving box, there are two lifting slides on the driving box for lifting and sliding, two sets of driving sprockets and driven sprockets are arranged on the top of the driving box, and the output shafts of the double-headed driving motor are respectively connected to the driving sprockets; the two lifting slides ensure that the adsorption bracket is firmly connected, and it can also be stable and reliable when flipped, and the two driving sprockets are driven by the double-headed driving motor to improve efficiency and reduce costs.

[0018] Furthermore, since the transverse slide bar is provided with a transverse slide seat that cooperates with the lifting slide seat, the transverse power device is a transverse linear motor, and the transverse linear motor is fixedly mounted on the lifting slide seat to drive the transverse slide bar to slide; the transverse linear motor drives the transverse slide seat to slide, which has a simple structure and is easy to drive, thereby improving the sliding efficiency of the transverse slide bar.

[0019] Furthermore, since the rotating power device includes a rotating cylinder, the rotating cylinder is fixedly mounted on the free end of the transverse sliding rod, and the rotating cylinder is connected and fixed to the frame cross bar through a connecting rod; the rotating cylinder is driven simply and reliably, thereby improving the flipping efficiency of the composite board.

[0020] Furthermore, since the limiting structure includes a limiting block and a pushing block fixedly installed at the adsorption station on the conveying bracket, the limiting block is located on one lateral side of the conveying bracket, and the pushing block is located on the other lateral side of the conveying bracket. The pushing block is driven to move laterally by a pushing cylinder. A fixed plate is provided on the conveying bracket, and the pushing cylinder is fixedly installed on the fixed plate. By pushing the pushing block to move laterally by the pushing cylinder, the composite plate can be driven to resist the limiting block, thereby ensuring the accurate position during each adsorption and more levelness during stacking.

[0021] Furthermore, since the conveying roller group is divided into several groups by the adsorption notch, each group of conveying rollers is sequentially connected through the transmission structure on the conveying bracket, and a transmission motor is provided at the bottom of the conveying bracket to drive one of the conveying rollers on each group of conveying rollers to rotate, thereby reducing the use cost and ensuring the conveying efficiency.

It has a simple structure and is easy to drive, thereby improving the sliding efficiency of the transverse slide bar 7; the transverse slide 18 and the transverse slide bar 7 are common linear motor drive structures on the market through the transverse linear motor 19, so they are not described in detail in the text.

[0035] In this embodiment, the rotating power device includes a rotating cylinder 20, which is fixedly installed on the free end of the transverse sliding rod 7, and the rotating cylinder 20 is connected and fixed to the frame cross bar 11 through a connecting rod 8; in this way, the orientation of the front and back sides of the composite board can be changed, and the front side of the composite board can be effectively protected. At the same time, the driving of the rotating cylinder 20 is simple and reliable, which improves the flipping efficiency of the composite board; the rotating cylinder 20 is also an existing structure that can be purchased on the market, so it is not described in detail in this article.

Then the composite board continues to be transported, and the adsorption bracket 9 makes the adsorption cup 12 adsorb the composite board upward. Then after rising, the adsorption bracket 9 is flipped downward again, so that the front side of the composite board faces downward, and then the pushing block 22 is pushed to limit the position, and then adsorption is performed again, and it is moved to the stacking station 5, so that the front side of the composite board adsorbed this time is overlapped with the front side of the composite board stacked last time, and the back side of the composite board faces upward, followed by the front side of the next composite board, so that the two back sides are stacked together.
