[0030] A three-dimensional shelf 1 is provided with a lifting frame 3 along its height, and the three-dimensional shelf 1 is provided with multiple layers of brackets at equal distances in the longitudinal direction, and multiple storage areas 11 for storing a feed frame 110 are arranged horizontally on each layer of brackets, and goods are placed in the feed frame 110; multiple cargo aisles are arranged on the storage area 11, and both ends of each cargo aisle are formed with entrances and exits for the feed frame to enter and exit; a conveying lane 111 is formed between two adjacent storage areas 11, and a track 12 is provided on the conveying lane 111; the lifting frame 3 is located at one end of the conveying lane 111, and a lifting platform that can be lifted and lowered along its height is slidably connected to the lifting frame 3; the conveying lane 111 is provided with a docking port connected to the lifting platform; accordingly, when the lifting platform moves to one end of the conveying lane 111, the RGV handling robot 2 can enter the lifting platform from the docking port, and switch to each layer of brackets at will through the lifting platform, thereby improving its flexibility and reducing manufacturing costs.

[0031] RGV handling robot 2, the RGV handling robot 2 is slidably connected to the conveying lane 111, and includes a frame 21 and a loading base 22 for placing the material frame 110; the frame 21 is slidably connected to the track 12; the loading base 22 can be lifted and lowered and connected to the frame 21; the loading base 22 is provided with a linear guide rail 26 along its length, and a picking component 23 for taking out the material frame 110 is slidably connected to the linear guide rail 26, and the picking component 23 includes a picking arm 24 that can rotate 360 ​​degrees in the horizontal direction and a reversing drive mechanism that drives the picking arm 24 to rotate, one end of the picking arm 24 is a fixed end 2402, and the fixed end 2402 is fixedly connected to the power end of the reversing drive mechanism, and the other end has a hook-shaped connecting end 2401 that can be connected to the material frame 110, and the hook-shaped connecting end 2401 rotates as the reversing drive mechanism drives the picking arm 24 to rotate in the horizontal direction, thereby realizing reversing and taking out the material frame 110. Accordingly, the RGV transport robot 2 retrieves the material frame on the left storage area or the material frame on the right by rotating the picking arm 24 .

[0032] In the design scheme of the present invention, the reversing drive mechanism includes a sliding plate 233, a first driving motor 231 and a reversing shaft 232. The bottom of the sliding plate 233 is slidably connected to the linear guide rail 26.

[0033] In the design of the present invention, two sets of lifting mechanisms 25 are also provided on the frame 21, and the two sets of lifting mechanisms 25 are symmetrically arranged on both sides of the loading base 22. The lifting mechanisms 25 include a mounting bracket 254, a screw rod 252, a nut block 253 slidably connected to the screw rod 252, and a second drive motor 251 driving the screw rod 252 to rotate.

[0035] In the design solution of the present invention, a positioning sensor is further disposed on the object carrying base 22 to locate the position of the object carrying base 22 .

[0036] In the design scheme of the present invention, the four corners of the frame 21 are rotatably connected to wheels 211, and a mobile driving mechanism for driving the wheels 211 to rotate is provided on the frame 21. The wheels 211 are slidably connected to the track 12, and driven by the mobile driving mechanism to rotate along the track 12.

[0037] In the design scheme of the present invention, the picking arm 24 is designed in an inverted "L". Accordingly, the picking arm 24 of the RGV handling robot 2 has a simple structure and is easy to maintain in the later stage, with low maintenance cost.

[0038] In the design of the present invention, a plug-in slot and a plug-in block are respectively provided on both sides of the feed frame 110; the plug-in block of one feed frame 110 is vertically plugged into the plug-in slot of another feed frame 110 between two adjacent feed frames 110. Accordingly, when the first feed frame 110 in the same cargo channel is dragged, the other feed frames 110 can also move with it.

[0039] As another embodiment of the present invention, a telescopic mechanism is also provided on the reversing shaft 232, and the telescopic mechanism is fixedly connected to the pickup arm 24, and is used to drive the pickup arm 24 to rise. Accordingly, the telescopic mechanism of the present application can be an electric push rod, which is used to drive the pickup arm 24 to rise and separate it from the insertion slot of the material frame 110.

[0040] The working principle of RGV handling robot 2 is as follows:

[0041] The RGV handling robot 2 moves on the conveying lane 111 and locates to the position where the material frame 110 needs to be picked up; then the lifting mechanism 25 drives the loading base 22 to rise to a preset height, and at the same time, the reversing drive mechanism drives the picking arm 24 to rotate to a preset direction, and the picking transmission mechanism 20 drives the picking arm 24 to move along the linear guide rail 26 on the loading base 22 toward the material frame 110 to be picked up; when the picking arm 24 reaches the preset position, the lifting mechanism 25 drives the hook-shaped connecting end 2401 of the picking arm 24 As the loading base 22 descends, the hook-shaped connecting end 2401 is vertically inserted into the insertion slot of the first material frame 110 in the cargo channel; the picking transmission mechanism 20 drives the picking arm 24 to return to the preset position along the linear guide rail 26 on the loading base 22, and at the same time pulls the material frame 110 connected thereto into the loading base 22; when the material frame 110 connected to the picking arm 24 enters the loading base 22, the second material frame 110 connected to the first material frame 110 also moves synchronously to the position of the first material frame 110. Finally, the lifting mechanism 25 drives the loading base 22 to rise again, so that the plug-in block of the first material frame 110 is separated from the plug-in slot of the adjacent material frame 110, and the material frame 110 is taken out of the inventory area 11 to the RGV handling robot 2. After the RGV handling robot 2 enters the lifting platform from the docking port, the lifting platform is lowered to the ground along the lifting frame 3, and the RGV handling robot 2 drives out of the lifting platform and transports the material frame to the designated position.
