The transmission is convenient, and a clamping groove 28 is provided on the inner wall of the reel 27.

[0038] When the warehouse door 18 is closed normally, the controller 13 reverses the protective motor 23, and the card block 26 is engaged in the card slot 28. At this time, the locking block 110 applies a limiting force to the reel 27 through the locking spring 111, and the reel 27 applies a limiting force to the fixed shaft 22 through the card block 26. The fixed shaft 22 applies a limiting force to the driving wheel 21, and the driving wheel 21 applies a limiting force to the warehouse door 18 through the transmission wheel 19, so that the warehouse door 18 remains stable when closed and is not easily opened by force.

[0039] The robot warehouse abnormal opening alarm method includes the following steps:

[0040] S1, the processor 12 does not issue a permission instruction;

[0041] S2, the door 18 is abnormally opened;

The protection motor 23 drives the protection shaft 24 to rotate, and the protection shaft 24 drives the screw 25 to rotate. The screw 25 moves under the action of the threaded hole, and the screw 25 drives the card block 26 away from the card slot 28. At this time, the locking spring 111 drives the locking block 110 to be engaged in the gear teeth on the outside of the protective cover 16. The locking block 110 limits the rotation of the protective cover 16, so that the protective cover 16 can play an anti-theft role and ensure transportation safety.

[0050] After the abnormal alarm is handled, the warehouse door 18 is closed, and the controller 13 reverses the protection motor 23, which drives the protection shaft 24 to reverse, and the protection shaft 24 drives the screw 25 to reverse, and the screw 25 drives the block 26 to be connected in the slot 28 through the threaded hole, and then the driving wheel 21 is controlled to rotate, and the driving wheel 21 drives the reel 27 to rotate, and the reel 27 drives the locking block 110 away from the protective cover 16 through the transmission rope, and then the protective cover 16 is reset by controlling the reset wheel 113 to rotate, and the protection motor 23 is rotated again by the controller 13, and the protection motor 23 drives the block 26 away from the slot 28, and the locking block 110 fixes the protective cover 16, and the device completes the reset.

[0051] Then the warehouse door 18 is closed normally, the controller 13 reverses the protective motor 23, and the block 26 is engaged in the slot 28. At this time, the locking block 110 applies a limiting force to the reel 27 through the locking spring 111, the reel 27 applies a limiting force to the fixed shaft 22 through the block 26, the fixed shaft 22 applies a limiting force to the driving wheel 21, and the driving wheel 21 applies a limiting force to the warehouse door 18 through the transmission wheel 19, so that the warehouse door 18 remains stable when closed and is not easily opened by force.
