[0025] See also Figures 2 to 3 In order to stack and move the pallets up and down, the mobile mechanism 2 in this embodiment includes two linear modules 21 fixed to the upper surface of the gantry 1. The upper surfaces of the two linear modules 21 are fixed with a transverse frame 22. A mobile platform 23 is slidably connected between the front and rear inner walls of the transverse frame 22. The mobile platform 23 is positioned on the gantry 1 through the two linear modules 21, ready for the movement or stacking of the pallets. Two connecting frames 24 are fixed to the lower surface of the mobile platform 23. The mobile platform 23 drives the transverse frame 22 along the front and rear directions. Move to the target position, close to the pallet stacking area or the pallet to be stacked, the inner walls of the two connecting frames 24 are rotatably connected to the axles 25, and pulleys 26 are fixed to the front and rear ends of the two axles 25. Guide rails 27 are fixed to the inner walls of the front and rear sides of the transverse frame 22, and the front and rear pulleys 26 are respectively slidably connected to the outer sides of the two guide rails 27. The upper surface of the mobile platform 23 is provided with a driving member 28 for driving the pulley 26 to rotate, and the driving motor 281 drives the driving gear 283 to rotate, which engages with the driven gear 284 on the axle 25.

[0026] The driving member 28 includes a driving motor 281 fixed to the upper surface of the mobile platform 23. A connecting shaft 282 is fixed to the outer side of the output shaft of the driving motor 281. The bottom end of the connecting shaft 282 passes through and extends to the bottom of the mobile platform 23 and is fixed with a driving gear 283. A driven gear 284 that meshes with the driving gear 283 is fixed to the outer side of the left axle 25. The driving pulley 26 rotates to move the mobile platform 23 along the guide rail 27. After the mobile platform 23 reaches the designated position, the stacking mechanism 3 is ready to perform the pallet picking and placing operation.

[0027] In this embodiment, the driving gear 283 and the driven gear 284 are both bevel gears, a conveyor belt is provided between the left and right inner walls of the gantry 1, the cross-section of the pulley 26 is H-shaped, and the distance between the front and rear inner walls of the pulley 26 is equal to the width of the guide rail 27.

[0028] See also Figures 4 and 5 In order to stack and place the pallets, the stacking mechanism 3 in this embodiment includes a support frame 31 fixed on the upper surface of the mobile platform 23. The support frame 31 is provided with a movable opening 32 on the side opposite to the mobile platform 23. The inner wall of the movable opening 32 is slidably connected with an upper and lower block 33. The lower surface of the upper and lower blocks 33 is fixed with a pneumatic clamp 34, which is equipped with a visual camera. The system will use it to identify the position and status of the pallet to ensure accurate placement. The pneumatic clamp 34 is adjusted to the appropriate position according to the information provided by the visual camera.

The upper and lower blocks 33 and the pneumatic clamp 34 return to their initial positions and prepare for the next pick-up and placement operation.

[0030] The working principle of the above embodiment is:

[0031] (1) When moving pallets up and down for stacking, the mobile platform 23 is positioned on the gantry 1 by two linear modules 21, and is ready for moving or stacking the pallets. The mobile platform 23 drives the transverse frame 22 to move to the target position in the front-to-back direction, close to the pallet stacking area or the pallet to be stacked. The driving motor 281 drives the driving gear 283 to rotate, and by engaging with the driven gear 284 on the axle 25, the driving pulley 26 rotates, so that the mobile platform 23 moves along the guide rail 27. After the mobile platform 23 reaches the designated position, the stacking mechanism 3 is ready for the pallet pick-up and placement operation.

[0032] (2) When stacking and placing pallets, a visual camera is provided, which the system uses to identify the position and status of the pallet to ensure accurate placement. The pneumatic clamp 34 is adjusted to the appropriate position to prepare for clamping the pallet based on the information provided by the visual camera. The adjustment motor 37 drives the transmission gear 38 to engage with the tooth plate 36, so that the upper and lower blocks 33 move to the appropriate position. The pneumatic clamp 34 is aligned with the pallet. The pneumatic clamp 34 clamps the pallet according to the instruction, and then the upper and lower blocks 33 rise to lift the pallet from the ground or other positions. The upper and lower blocks 33 carry the pallet vertically to the stacking position. During this process, the limit plate 39 ensures that the upper and lower blocks 33 move stably. The pneumatic clamp 34 is released and the pallet is placed on the specified stacking layer to complete a stacking cycle. The upper and lower blocks 33 and the pneumatic clamp 34 return to the initial position to prepare for the next placement operation.
