Follow the steps below to use:

Step 10: Open the hatch on the cabin 1;

Step 20: Place the item on the placement table in the cabin 1;

Step 30: close the cabin door; control the encoder motor 18 to operate through the external controller, and make the encoder motor 18 rotate and rotate through the action of the gear set of the rotating box, so that the rotation rotates, thereby driving the rotating block 22 to rotate, Until the hatch 27 opens/closes the hatch, when the object/hand is clamped by the hatch 27, the hatch 27 squeezes the object/hand, and when the object/hand is squeezed by the hatch 27, the safety touch is performed. Squeeze, so that the safety edge is deformed, so that the safety edge in the normally open state generates a normally open and closed electrical signal due to the extrusion of the object/hand. At the same time, the door 27 cannot be blocked due to the object/hand. Closed, the rotation speed of the encoding motor 18 is reduced due to blockage, and the current increases. The controller of the encoding motor 18 detects the signal of the current increase, and transmits the signal and the electrical signal to the controller of the robot, so as to change the encoding motor. 18 turn the command to the controller of the coding motor 18, stop the rotation of the closing direction of the hatch door, and turn it in the opposite direction at a certain angle, so that the stuck object/hand can be taken out of the hatch door normally, ensuring the safety of the hand, In addition, the object is prevented from being damaged due to extrusion, and at the same time, through the provision of the rotation auxiliary member, the cabin door 27 is prevented from rubbing against the mounting block 21 during rotation, resulting in damage to the cabin door 27/mounting block 21 .

Step 50: Start the ultraviolet disinfection device 3 and the liquid disinfection device 4 to sterilize the articles; the disinfection time of the ultraviolet disinfection device is longer than 15 minutes. It is better to control the time of ultraviolet disinfection between 15 minutes and 20 minutes. If the time is too short, the disinfection may not be thorough enough. If the time is too long, the space in the cabin 1 may heat up, which will affect the low-temperature items in the distribution. The sterilization time of the liquid sterilizing device 4 is less than 10 minutes. The time of the liquid disinfection device 4 is controlled within 10 minutes, and it can cooperate with the ultraviolet disinfection process of 15 minutes to 20 minutes. If the two are activated at the same time, there will be 5 minutes to 10 minutes for the disinfection liquid beads on the surface of the delivery item 11 to volatilize. . It is ensured that when the delivery is completed and taken out, there will be no obvious disinfectant liquid on the delivery item 11 . The installation table works when the liquid disinfection device 4 sprays the disinfection liquid, and the rolling rod 9 of the installation table is rotated so that the disinfection liquid can take effect on the bottom of the object. The rolling bar 9 is rolled, and the bottom part of the delivery item 11 in contact with the rolling bar 9 is moved to be out of contact with the rolling bar 9 to be exposed to the air with the droplets of sterilizing liquid in the cabin 1 .

Step 60: Turn off the ultraviolet disinfection device 3 and the liquid disinfection device 4 after the disinfection is completed;

Step 70: Open the hatch on the cabin 1;

Step 80: Take out the sterilized object on the placement table;

Step 90: Close the hatch. The encoder motor 18 is controlled to operate by an external controller, and the encoder motor 18 is driven to rotate by the action of the gear set of the rotating box, so that the rotation rotates, thereby driving the rotating block 22 to rotate until the door 27 is opposite to the door. Open/close, when the object/hand is clamped by the hatch 27, the hatch 27 squeezes the object/hand, and when the object/hand is squeezed by the hatch 27, it squeezes the safety edge to make the safety edge Deformation occurs, so that the safety contact in the normally open state generates a normally open and closed electrical signal due to the extrusion of the object/hand. At the same time, the hatch 27 cannot be closed due to the blockage caused by the object/hand, resulting in the coding motor 18. The rotation speed decreases due to the blockage, and the current increases. The controller of the encoder motor 18 detects the signal of the current increase, and transmits the signal and the electrical signal to the controller of the robot, so as to issue a command to change the direction of the encoder motor 18 to the encoder motor. The controller of 18 stops the rotation of the closing direction of the door, and rotates it in the opposite direction at a certain angle, so that the stuck object/hand can be taken out of the door normally, ensuring the safety of the hand and preventing the object from being squeezed. At the same time, through the provision of the rotation auxiliary member, the cabin door 27 is prevented from rubbing against the mounting block 21 during rotation, resulting in damage to the cabin door 27/the mounting block 21.

Wherein, the cabin 1 is in a delivery moving state in steps 50 and 60 . When the service robot distributes the items, it sterilizes and disinfects the distributed items, and effectively utilizes the disinfection time and delivery time.

The device adds UVC ultraviolet LED and alcohol disinfection spraying system to the traditional distribution box, uses the sterilization properties of ultraviolet rays and alcohol to bacteria and viruses, effectively kills the distributed objects, and effectively reduces the harm caused by virus cross-infection to users.
