[0035] The implementation principle of the mechanical hand for the smart access cabinet is as follows:

[0036] When the two multi-stage electric push rods 18 are in the retracted state, the forward and reverse motor 8 drives the gear 9 to rotate, so that the rack 10, the sliding block 11 and the baffle 12 approach the position of the electronic scale 22. After the operator places the tray 23 on the electronic scale 22 and weighs it, the operator places the tray 23 on the rack 10, presses the controller on the intelligent access cabinet 1, and the controller controls the forward and reverse motor 8 to drive the gear 9 to rotate. The gear 9 engages the rack 10 to make the tray 23 in the middle position. Then the controller controls the linear module one 3 and the linear module two 4 to work. The linear module one 3 drives the linear module two 4, the sliding block 5 and the connecting frame 6 structure to slide horizontally. The linear module two 4 drives the sliding block 5 and the connecting frame 6 to slide vertically. The controller will accurately move the tray 23 to the position of the vacant front bin 20 or rear bin 21. For example, the third row second compartment of the front bin 20 is in an empty state. At this time, the controller will control the tray 23 to stop at the third row second compartment of the empty front bin 20. The controller will then control the forward and reverse motor 8 to rotate forward or in reverse, so that the rack 10 moves to the third row second compartment of the front bin 20. When the tray 23 moves above the pressing block 17, the tray 23 will press the pressing block 17 and the multi-stage electric push rod 18 downward and move horizontally from the pressing block 17. When the tray 23 leaves the pressing block 17, the spring 16 will drive the sleeve rod 15 to lift the multi-stage electric push rod 18 and the pressing block 17. When the tray 23 is placed in the third row second compartment of the front bin 20, the rack 10 contacts the bottom of the third row second compartment of the front bin 20. At this time, the multi-stage electric push rod 18 needs to work.

[0037] The controller controls the output end of the multi-stage electric push rod 18 to push out from the input end. When the output end of the multi-stage electric push rod 18 contacts one side of the tray 23 and pushes it, the tray 23 can be pushed into the third row second compartment of the front bin 20. Then the controller controls the multi-stage electric push rod 18 and the forward and reverse motor 8 to reset.

[0038] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered by the protection scope of the present application.
