[0002] An automatic guided vehicle, also called an AGV vehicle, is an unmanned transport vehicle equipped with an automatic guidance device such as electromagnetic or optical. It can travel along a specified guidance path and has safety protection and various transfer functions. AGV vehicles usually use rechargeable batteries as the power source and are controlled by a computer system for their travel routes and behaviors. The main functions of AGV vehicles include material handling, automatic charging, path planning, etc. They are widely used in multiple industries such as warehousing, logistics, automobile manufacturing, and healthcare. Their advantages include high automation, automatic charging, improved production efficiency, reduced labor costs, etc. There are various types of AGV vehicles, such as towing type, pallet type, forklift type, etc., which can be selected according to different application scenarios and requirements.

[0003] In the actual use process of AGV vehicles, there is a situation where it is necessary to remove and collect the empty pallets on one AGV vehicle and then place the empty pallets on another AGV vehicle. For example, a fully automatic pallet collection device based on an AGV vehicle with the publication number CN119660396A includes a placement frame. An operation space is formed inside the placement frame for the AGV vehicle to enter and exit. A synchronous belt drive lifting mechanism and a positioning clamping telescopic mechanism are arranged on the placement frame. The synchronous belt drive lifting mechanism clamps the pallet on the AGV vehicle through the clamping jaw telescopic mechanism, so that the synchronous belt drive lifting mechanism can drive the pallet to move vertically through vertical movement, and the positioning clamping telescopic mechanism is used to calibrate the position of the pallet on the AGV vehicle.

[0043] When the two folding plate clamps 11 are moved to the bottom of the pallet on the AGV trolley, the two lifting plates 6 are first driven to rise by the double-output shaft motor 13, and the two folding plate clamps 11 can lift the pallet on the AGV trolley, so that the pallet contacts and stacks with the upper pallet, and the previously stacked pallet is lifted to a certain height, so that the multiple support rods 5 do not bear the weight of the pallet at this time, that is, there is a gap between the multiple support rods 5 and the previously contacted pallet, and the first electric cylinder 3 can drive the support rods 5 to retract and disengage from the pallet;

[0044] Then, the two folding plate clamps 11 continue to lift the stacked pallets, so that the bottom pallet is higher than the height of the multiple support rods 5. At this time, the first electric cylinder 3 drives the support rods 5 to extend, so that the multiple support rods 5 are all extended to the bottom of the bottom pallet;

[0045] Finally, the two lifting plates 6 are driven to descend and reset by the double-output shaft motor 13, and the multiple supporting rods 5 can support the stacked multiple pallets, so that the lifting mechanism lifts the pallets on the AGV trolley and transports the pallets to the supporting mechanism, and the supporting mechanism bears the weight of the stacked multiple pallets. Compared with the prior art, the stacked pallets in this application will not be placed on the AGV trolley, avoiding the AGV trolley from being damaged due to overloading;

[0049] like Figure 4 and Figure 5 When the folding plate clamp 11 moves to the bottom of the tray on the AGV trolley, the driving assembly drives the turntable 19 to rotate, and the turntable 19 can push the two sliding sleeves 21 away from each other through the two protruding rods 20 thereon, and the two sliding sleeves 21 push the push plates 23 to move through the push rods 22, so that the two push plates 23 respectively contact the two supporting feet at both ends of the tray;

[0050] The multiple push plates 23 on the two folding plate clamps 11 can respectively contact the four supporting feet of the pallet, and then cooperate with the two folding plate clamps 11 to clamp the pallet, so as to correct the deviation of the pallet on the AGV trolley and ensure that the pallet on the AGV trolley is aligned with the pallet stacked above.

[0051] As a preferred embodiment of the present application, the driving assembly includes a driving motor 24, a gear 25 and an outer gear ring 26.

Figure 1 and Figure 3 The plurality of limiting covers 28 can support and limit the stacked pallets in the vertical direction to prevent the stacked pallets from tipping over.

[0055] Working principle: When the AGV trolley drives the pallet on it to move to the bottom of the rack 1, the two lifting mechanisms are respectively located on both sides of the AGV trolley, and the folding plate clamp 11 is pushed toward the pallet on the AGV trolley by the second electric cylinder 10, so that the two folding plate clamps 11 on the two lifting mechanisms are moved to the bottom of the pallet on the AGV trolley;

[0056] Then, the two lifting plates 6 are driven to rise by the double-output shaft motor 13, and the two folding plate clamps 11 can lift the pallet on the AGV trolley, so that the pallet contacts and stacks with the upper pallet, and the previously stacked pallet is lifted to a certain height, so that the multiple support rods 5 do not bear the weight of the pallet at this time, that is, there is a gap between the multiple support rods 5 and the previously contacted pallet, and the first electric cylinder 3 can drive the support rods 5 to retract and disengage from the pallet;

[0057] Subsequently, the two folding plates 11 continue to lift the stacked pallets, so that the lowermost pallet is higher than the height of the plurality of support rods 5. At this time, the first electric cylinder 3 drives the support rods 5 to extend, so that the plurality of support rods 5 all extend below the lowermost pallet;

[0058] Finally, the double-output shaft motor 13 drives the two lifting plates 6 to descend and reset, and the plurality of support rods 5 can support the stacked pallets, thereby completing the lifting mechanism to lift the pallets on the AGV cart and transport the pallets to the lifting mechanism. The lifting mechanism bears the weight of the stacked pallets. Compared with the prior art, in this application, the stacked pallets are not placed on the AGV cart, avoiding damage to the AGV cart due to exceeding the limit load.
