During the flipping action, the flipping drive mechanism 21 is started, driving the flipping frame 22 to flip, and the clamping device 3 clamps the material box 6 and flips synchronously with the flipping frame 22.

[0040] The flipping drive mechanism 21 includes a flipping power assembly 211, which is fixedly arranged on the mobile frame 12.

The number of the flipping power assemblies 211 is set to two, and the two flipping power assemblies 211 are symmetrically arranged on both sides of the flipping frame 22, and the two flipping power assemblies 211 act synchronously.

[0041] The two synchronously acting flipping power components 211 drive the flipping frame 22 to flip, so that the two sides of the flipping frame 22 are evenly stressed, the flipping process is smooth and impact-free, and during the flipping process, the material box 6 can hover at any angle to meet special needs such as controlling the amount of material input during unloading.

[0061] Example 4 Example 4 is based on Example 3: Example 4 takes a box-type stereoscopic warehouse that uses a box robot to store and retrieve goods as an example. Assuming that the box robot has multiple boxes 6 that need to be unloaded at the same barrel 7, the steps are as follows: In step (I), the material box robot moves the material box 6 loaded with materials to the material box automatic unloading equipment, and then sends a release request signal to the PLC control box. After receiving feedback and allowing the release, the material box robot places the material box 6 loaded with materials on the loading platform and exchanges information with the PLC control box to confirm necessary information such as material information and quantity.

[0062] Step (II), after the material box robot completes the release action and sends a release completion signal to the PLC control box, the moving device 1 retracts to move the clamping device 3 to the position corresponding to the material box 6 loaded with materials, then the clamping device 3 clamps the material box 6 loaded with materials, and the moving device 1 extends to drive the flipping device 2 and the clamping device 3 to extend synchronously, so that the material box 6 is moved into the barrel 7 through the feeding port 71; Step (III), the turning device 2 turns inside the barrel 7, driving the clamping device 3 to turn over, and unloading the material in the material box 6 into the barrel 7; Step (IV), after unloading is completed, the turning device 2 returns to its original position so that the opening of the empty material box 6 faces upward, the moving device 1 is retracted, and the clamping device 3 releases the empty material box 6. Then, the moving device 1 extends. At this time, the moving device 1, the turning device 2 and the clamping device 3 return to their initial positions, and the empty material box 6 is located on the loading platform; In step (V), the PLC control box sends a signal to the material box robot allowing the material box to pick up the goods. The material box robot takes away the empty material box 6 and feeds back a picking completion signal to the PLC control box. The various storage information and equipment status of the material box automatic unloading equipment are reset, and the material box unloading process is completed.

[0063] Step (VI), the material box robot repeats the above process to complete the successive unloading of multiple material boxes 6.
