The pallets loaded with products are transported to the first pallet position in sequence by the first lifting mechanism. When the products in the pallets located at the first pallet are taken out by the feeding mechanism 500, the empty pallet 30 located at the first pallet position 130 is taken away by the pallet transfer mechanism or manually, and then the first lifting mechanism 200 drives the stacked pallets 30 to move upward, so that the next pallet 30 loaded with products (the top pallet 30 at this time) moves to the first pallet position 130.

[0046] Further, refer to Figure 2 , Figure 5 and Figure 6 The first lifting mechanism 200 includes a receiving platform 212; the receiving platform 212 is used to receive the first material box 10, the first material box 10 is used to stack the tray 30 containing the product, and the first material box 10 has an upper box opening. The first material box 10 is set according to the shape of the tray 30 to adapt to the stacked tray 30. The first material box 10 is mainly rectangular, and of course it can also be other shapes. The lifting mechanism 200 further includes a lifting drive assembly 220 and a lifting frame 230; the lifting drive assembly 220 is arranged on the bracket, and the lifting frame 230 is arranged at the lifting end of the lifting drive assembly 220; the lifting frame 230 is provided with at least one vertically arranged top rod 240; at least one through hole 11 is penetrated through the bottom of the first material box 10, and the lifting drive assembly 220 is used to drive the top rod 240 to move up and down, so that the top rod 240 moves up through the through hole 11 and extends into the first material box 10 and drives the stacked trays 30 in the first material box 10 to be transported upward in sequence, or the top rod 240 moves down and drives the stacked trays 30 in the first material box 10 to be transported downward in sequence. In a specific embodiment, the lifting frame 230 is located below the receiving platform 212, and the lifting frame 230 is arranged horizontally. When the empty pallet 30 at the first pallet position 130 is taken away by the adsorption head 431, the lifting drive assembly 220 drives the top rod 240 to move upward to continue to transport the next pallet 30 (the top pallet 30 at this time) in the first material box 10 upward to the first pallet position 130, and the cycle is repeated, so that the stacked pallets 30 (pallets with products) in the first material box 10 are moved to the first pallet position 130 in sequence.

That is, after the products in the tray 30 located at the first tray 3030 are taken by the loading mechanism 500, the Y-axis transfer component 420 and the second Z-axis transfer component 430 drive the suction head 431 to approach the empty pallet 30 located at the first pallet position 130, and the suction head 431 sucks the empty pallet 30 through negative pressure, and then the Y-axis transfer component 420 and the second Z-axis transfer component 430 drive the suction head 431 and the empty pallet 30 to move to the second pallet position 140, and the suction head 431 removes the negative pressure to stack the empty pallet 30 on the second pallet position 140, without the need for manual collection and stacking of the empty pallets 30.

The structure of the second lifting mechanism 300 is consistent with that of the first lifting mechanism 200, and the structure of the second material box 20 is consistent with that of the first material box 10. When the products in the tray 30 located at the first tray position 130 are taken out, the Y-axis transfer component 420 and the second Z-axis transfer component 430 drive the suction head 431 to transfer the empty tray 30 located at the first tray position 130 and stack it on the second tray position 140, and the second lifting mechanism 300 transports the empty tray 30 downward and enters the second material box 20; at the same time, after the tray 30 located at the first tray position 130 is taken out, the first lifting mechanism 200 continues to transport the next tray 30 containing products in the first material box 10 (at this time it is the top tray 30) upward to the first tray position 130, and repeats this cycle until the products of the last tray 30 in the first material box 10 are taken out, and the suction head 431 stacks the last empty tray 30 on the empty tray 30 on the second lifting mechanism 300, so that the second lifting mechanism 300 stacks all the empty trays 30 into the second material box 20, without the need for manual picking and stacking of the empty trays 30, thereby reducing labor costs and improving work efficiency.
