The clamping principle of the above-mentioned L-shaped pallet 343 is as follows. After the driving mechanism 333 has stacked the plates to a preset height by the external stacking equipment in this application, the external driving equipment drives the clamping device to move to an appropriate position. At this time, the driving mechanism 333 realizes the contraction action, that is, the push lever 331 rotates counterclockwise. At this time, the two groups of push rods 332 move toward each other, thereby pulling the driving end of the clamping mechanism 34, forcing the L-shaped support plate 343 to surround it and the turret 35. The connection point of the swivel swings outward to realize the opening action of each pair of L-shaped pallets 343, so that the external driving device can drive the clamping device to move downward until it contacts with the stacked plates, and then the driving mechanism 333 outwards During the extending action, the lever 331 rotates clockwise and forces the two sets of push rods 332 to move outward respectively, and then pushes the L-shaped support plates 343 on both sides to realize the folding action, so that the two sets of L-shaped support plates 343 can respectively stack the plates. The two sides of the plate are clamped inward and the entire stack of plates is held up.

In addition, in the present application, the swing arm 344 is arranged opposite to the L-shaped pallet 343 in the present application. Therefore, the driving mechanism 333 and the driving link assembly 33 in the present application are both arranged on the upper surface of the turret 35, while The working end of the L-shaped supporting plate 343 protrudes from the lower surface of the turret 35. When the L-shaped supporting plates 343 on both sides cooperate with each other to clamp and hold up the plates, the horizontal part of the L-shaped supporting plate 343 acts as a supporting plate. It acts as a plate, and the vertical part of the L-shaped support plate 343 can smooth the effect of different layers of plates on the plate stack during the opening and closing process of the L-shaped plate 343, so that the plate stack can be stacked flat.

The plate production line of the present invention uses the receiving guide plate 121 to guide the plates conveyed by the pinch device 11 one by one, so that the plates can be neatly stacked on the plate receiving device 13, and the receiving guide plate 121 can adjust the opening and closing angle to adapt to plates of different specifications stacking requirements. In addition, by using the moving device 31 as the driving base structure, the rotating device 32 can be driven to realize a spatial displacement action, which improves the flexibility of the entire equipment and is suitable for stacking requirements in different environments. In addition, a plurality of pairs of clamping mechanisms 34 that open and close in opposite directions are designed, and each pair of clamping mechanisms 34 is driven to swing relative to each other by the driving link assembly 33, so as to realize the opening and closing operations of each pair of clamping mechanisms 34 and realize synchronous opening and closing. The clamping action avoids the phenomenon that the clamping mechanism 34 is not prone to hook plates during clamping or unloading in the later stage, and improves the quality of the sheet stacking; at the same time, the clamping mechanism 34 is used to clamp and hold up the edges of both sides of the sheet stacking. It can effectively avoid the phenomenon of unstable clamping of warped plates in the stacking of plates, and improve the stability of handling. The board production line is ingeniously designed, can stack the boards flat, and can effectively clamp the warped board stacks, with strong flexibility.
