[0026] As Figure 1-7 shown, a three-dimensional storage folding tray device for a warehousing robot includes a base 10, a frame body 30, a vertical lifting device 20, a horizontal telescopic clamping device 40, and a three-dimensional shelf track 50.

[0027] The three-dimensional shelf track 50 is arranged on the base 10. Pallets can be placed on the three-dimensional shelf track.

[0028] The frame body 30 includes U-shaped frames symmetrically arranged on the left and right sides. The U-shaped frame includes two columns 31. The lower part of the column 31 is fixedly connected to the base 10, and a cross beam 32 is arranged above the column 31; the cross beam of the U-shaped frame plays a role in fixing the column. In order to make the U-shaped frame more stable, a fixing beam can be additionally arranged between the two U-shaped frames, so that the structures of the two U-shaped frames are more stable and the load-bearing capacity is stronger.

[0029] Lifting frame tracks 33 are arranged on the columns 31.

[0030] The base 10 and the frame body 30 constitute the entire frame system of the folding tray device. An outer shell 60 is arranged outside the frame body 30.

[0031] The vertical lifting device 20 includes a lifting drive assembly and a lifting frame 25; the lifting drive assembly includes a lifting drive motor 21 and a lifting transmission mechanism. Both sides of the lifting frame 25 are placed in the lifting frame tracks 33, and the lifting drive motor 21 controls the lifting frame 25 to move up and down in the vertical direction through the lifting transmission mechanism.

[0032] The lifting frame 25 is a "mouth"-shaped frame body, which includes an upper frame 251 and a lower frame 252. At least one side of the two side edges is provided with a guide wheel set, and the guide wheel set 253 is placed in the lifting frame tracks 33.

[0033] Specifically, the lifting transmission mechanism includes a first transmission chain 22, a first transmission sprocket, a first transmission shaft 23, a first lifting drive sprocket 26, and a first lifting drive chain 24. The first lifting drive chain 24 is connected to the lifting frame 25.

[0034] The first driving sprocket can be arranged on the lifting drive motor 21 or the first transmission shaft 23, and other transmission structures are used at the other end; at the same time, it should also be interpreted in a broad sense. In this embodiment, the first driving wheel can be a set of chain transmission gears respectively arranged on the lifting drive motor 21 and the first transmission shaft 23.

[0035] At the same time, in the present utility model, in an equivalent manner, those skilled in the art should understand that for the lifting transmission mechanism, in addition to the mentioned first transmission chain 22, first driving sprocket, first transmission shaft 23, first lifting drive sprocket 26, first lifting drive chain 24, etc., it can also be realized by similar methods such as a synchronous motor driving a pulley transmission, a gear transmission, a rack transmission, etc. The first transmission chain 22 and the first driving sprocket are only for the convenience of one embodiment of the present utility model.

[0036] The lifting drive motor 21 is fixed on the base 10, and the lifting drive motor 21 drives the first transmission shaft 23 through the first transmission chain 22 and the first driving sprocket; the first transmission shaft 23 is arranged at the middle position of the base 10, and the first transmission shaft 23 drives the first lifting drive chain 24 to move through the first lifting drive sprocket 26, so as to drive the lifting frame 25 to move up and down in the vertical direction.

[0037] Here, the middle position should be understood in a broad sense, and it is not limited to the symmetric center position. The present invention can be realized at any non-edge position of the base 10. Placing the transmission shaft at the middle position can better drive from the perspective of force and can better maintain stability.

[0038] The U-shaped frame is symmetrically arranged on the left and right sides. Therefore, as Figure 3 shown, the first lifting drive sprocket 26, the first lifting drive chain 24 and the lifting frame 25 are all arranged on both sides of the U-shaped frame. The first lifting drive sprockets 26 located on both sides of the U-shaped frame are simultaneously driven by the first transmission shaft 23. Compared with the embodiment in which motors are used to drive on both sides respectively, the structure of the present utility model can ensure that the two vertical lifting devices keep synchronous during operation, without the height difference between the two sides, and the operation is more stable.

[0039] Through holes are respectively arranged at the middle positions of the upper frame and the lower frame of the lifting frame for the first lifting drive chain to pass through. One end of the first lifting drive chain is connected to the upper end face of the upper frame, and the other end is connected to the lower end face of the lower frame; the upper part of the first lifting drive chain is wound around the pulley located on the cross beam 32, and the lower part is wound around the first lifting drive sprocket 26.

[0040] When the first transmission shaft rotates, it drives the first lifting drive sprocket 26 to rotate, and then drives the entire lifting frame to move up and down through the first lifting drive chain.

[0041] In this utility model, both ends of the first lifting drive chain are respectively connected to the upper frame and the lower frame. When moving in the vertical direction, whether ascending or descending, it is driven by a motor (through a lifting transmission mechanism), with more uniform force and more stable overall operation, enabling accurate control.

[0042] As other embodiments of the present invention, the vertical lifting device 20 can also be arranged above the frame body 30, and the up and down movement of the lifting frame is controlled by transmission methods such as belts, chains, gears, and racks 451.

[0043] The horizontal telescopic positioning device 40 includes a horizontal drive assembly and a horizontal telescopic positioning assembly. The horizontal drive assembly includes a horizontal drive motor 41 and a horizontal transmission mechanism. The horizontal drive motor 41 controls the horizontal telescopic positioning assembly to move in the horizontal direction through the horizontal transmission mechanism;

[0044] The horizontal telescopic positioning device 40 is arranged on the lower frame of the lifting frame 25.

[0045] The horizontal transmission mechanism includes a second transmission chain 42, a second transmission sprocket, a second transmission shaft 43, and a second gear 44; the horizontal telescopic positioning assembly includes a body, a telescopic plate 452, and a rack 451; the rack 451 is fixed above the telescopic plate 452.

[0046] The horizontal drive motor 41 drives the second transmission shaft 43 to rotate through the second transmission chain 42 and the second transmission sprocket, and then drives the second gear 44 on the second transmission shaft 43 to rotate. The second gear 44 drives the telescopic plate 452 to move in the horizontal direction through the rack 451.

[0047] Similarly, the second transmission sprocket can be arranged on the horizontal drive motor 41 or the second transmission shaft 43, and other transmission structures are used at the other end; at the same time, it should also be interpreted broadly. The second transmission sprocket can be a set of chain drive gears respectively placed on the horizontal drive motor 41 and the second transmission shaft 43.

[0048] In this utility model, as equivalent embodiments, those skilled in the art should understand that the second transmission chain 42, the second transmission sprocket, the second transmission shaft 43, etc. can also use similar methods such as pulley transmission, gear transmission, and rack transmission.

[0049] A buffer block 453 is installed at a position near the front end of the telescopic plate 452. The buffer block 43 has two functions. On the one hand, it plays a role in guiding and clamping the tray, and on the other hand, it can play a limiting role when the telescopic plate 452 retracts.

[0050] A limiting upper plate 454 and a limiting side plate 455 are provided at the rear end of the telescopic plate 452. The settings of the limiting upper plate 454 and the limiting side plate 455 can limit the movement of the telescopic plate in the vertical direction and left and right (relative to the telescopic direction of the telescopic plate), clamp the telescopic plate 452, so that it can only perform telescopic work, and prevent shaking and displacement in other directions.

[0051] At least two groups of horizontal telescopic clamping devices 40 are installed on each lifting frame 25. The function of the second transmission shaft 43 is similar to that of the first transmission shaft, and it can synchronously drive more than two groups of horizontal telescopic clamping devices 40.

[0052] An induction sheet 72 is installed on the lifting frame 25, and a photoelectric sensor 73 and a first travel switch 71 are correspondingly installed on the frame body 30 of the rack, which play a role in detecting the position of the lifting frame.

[0053] A trigger plate 46 is installed on the telescopic plate, and two second travel switches 47 are also correspondingly installed on the lifting frame, which play a role in detecting the position of the telescopic plate. When the telescopic plate moves under the driving action of the gear rack, the trigger plate also moves accordingly. When the trigger plate touches the travel switch in the front or the back, the second travel switch feeds back a signal, and the overall circuit is powered off, restricting the further movement of the telescopic plate to prevent it from falling off or being damaged beyond the stroke.

[0054] For the folding and unfolding tray device provided by the present utility model, the folding and unfolding tray method is as follows: When unfolding the tray, the pallet stack is stored on the three-dimensional shelf track. The vertical lifting device drives the lifting frame to move, so that the telescopic plate on the lifting frame is at the same height as the fork holes of the second tray from the bottom in the pallet stack. At this time, the horizontal telescopic clamping device drives the telescopic plate to move and clamp the pallet stack. Then the vertical lifting device drives the lifting frame to drive the pallet stack to move upward. The three-dimensional storage robot moves into the three-dimensional shelf track, transports out the tray, the vertical lifting device drives the lifting frame to drive the pallet stack to move downward, places the pallet stack on the three-dimensional shelf track, the telescopic plate retracts, and the above steps are repeated in sequence to realize unfolding the tray. Folding the tray is the reverse process of unfolding the tray.

[0055] The present utility model can automatically and intelligently realize the folding and unfolding of trays and the loading and unloading operations between the trays and the three-dimensional shelf, with high efficiency; the overall structure of the folding and unfolding tray device is relatively simple, with a high degree of modularization, convenient for installation, and also cost-saving.
