S6, the main control board controls the lifting mechanism 31 to move downwards slowly, and the sucking disc 33 adsorbs the license plate 5 to be released at the topmost end. After the suction cup 33 adsorbs the license plate 5 to be released, the pressure change of the vacuum license plate sucking system 34 is triggered, the pressure sensor 343 can detect the pressure change inside the suction cup 33, that is, the detected pressure value P1 is greater than the initial set pressure value P0, that is, the suction cup 33 adsorbs the license plate 5 to be released, and further, the main control board control device can conveniently perform the next action.

The main control board controls the lifting mechanism 31 to stop downward movement.

And S7, the main control board controls the lifting motor 313 to rotate reversely, the lifting motor 313 drives the manipulator lifting screw 311 to rotate reversely, the lifting screw 312, the horizontal guide rail 322, the moving platform 321 and the sucker 33 are further driven to ascend for a plurality of distances, and the horizontal guide rail 322 is driven by the guide rail driving motor to displace towards the left side and return to the middle position.

And S8, the main control board controls the operation of the moving platform driving motor to drive the moving platform 321 and the suction cup 33 to move leftwards to the position right above the camera 7.

S9, the main control board controls the lifting mechanism 31 to move downwards, and the license plate 5 to be released is brought to reach a specified distance close to the camera.

S10, the camera 7 carries out light supplementing and photographing on the license plate 5 to be sent above, photographing information is fed back to the industrial personal computer, and the industrial personal computer feeds the photographing information back to the main control board.

S11, the main control board allocates a license plate storage rack placing position for the license plate 5 to be placed in the storage.

S12, the main control board drives the rotating motor 23 to rotate, and further drives the rotating shaft 22 and the license plate storage rack 21 to rotate until the target license plate is placed right in the middle and towards the right side.

S13, the main control board controls the lifting mechanism 31 to drive the license plate 5 to be issued to move to the height of the target license plate placing position.

And S14, the horizontal guide rail 322 is driven by the guide rail driving motor to move towards the left side of the target license plate placing position until the left side boundary of the target license plate placing position.

And S15, when the license plate is moved to the left side in the step S14, the main control board controls the operation of the driving motor of the movable platform, and the movable platform 321 and the suction cup 33 displace the license plate 5 to be released to a plurality of heights above the target license plate placing position of the license plate storage rack 21 under the driving of the driving motor of the movable platform.

S16, the vacuum license sucking system 34 switches a vacuum loop through the electromagnetic valve 344 to release vacuum, and a license 5 to be released falls into a target license placing position.

S17, the horizontal rail 322 moves to the middle position under the driving of the rail driving motor.

And finishing the warehousing operation of the license plate 5 to be issued through the steps from S1 to S17.

When the license plate 5 to be issued is issued, the specific process is as follows.

S18, the identity of the masses is confirmed through the identity recognition module of the main control board, and the main control board inquires the license plate placing positions of the license plates of the masses on the license plate storage rack 21.

S19, the license plate storage rack 21 rotates under the driving of the rotating motor 23 until the target license plate placing position rotates to the right side.

S20, the main control board controls the lifting mechanism 31 to move to the position above the target license plate placing position.

S21, the horizontal guide rail 322 moves to the left side boundary of the target license plate placing position under the drive of the guide rail driving motor. Meanwhile, the moving platform 321 and the suction cup 33 are moved to above the target license plate under the driving of the moving platform driving motor.

S22, the main control board controls the lifting mechanism 31 to slowly move downwards until the vacuum card sucking system 34 senses the change of the vacuum degree, namely the pressure value P2 detected by the air pressure sensor 343 is larger than the initial set pressure value P0, which indicates that the suction cup 33 is adsorbed to the license plate 5 to be released, and further the main control board control device can conveniently perform the next action.

And S23, the main control board controls the lifting mechanism 31 to ascend to a certain height.

And S24, the horizontal guide rail 322 is driven by the guide rail driving motor to move back to the middle.

S25, the main control board controls the lifting mechanism 31 to move downwards to the height of the license plate access opening 4.

S26, the moving platform 321 and the sucker 33 move the license plate 5 to be released to the license plate receiving opening 4 under the driving of the moving platform driving motor.

S27, the vacuum license sucking system 34 switches the license sucking air path, the suction disc 33 releases the license 5 to be released, and the license 5 to be released falls into the license receiving opening 4.

Through the steps from S1 to S27, the license plate 5 to be issued is received, so that the masses can conveniently and automatically receive the license plate 5 to be issued.
