[0002] During the production process of motor vehicle license plates, a two-dimensional code needs to be endorsed on the semi-finished motor vehicle license plate as the identification serial number of the semi-finished motor vehicle license plate. The endorsement operation is completed by laser printing on the semi-finished motor vehicle license plate by an endorsing machine.

[0003] Currently, the semi-finished motor vehicle license plates are conveyed by a conveyor belt.

[0021] Such as Figures 1 to 8As shown in the figure, the intelligent parking and sorting equipment for motor vehicle license plates according to the embodiment of the present invention includes a license plate conveyor belt device 100 for conveying semi-finished motor vehicle license plates, at least two groups of transverse parking devices 200 arranged at intervals along the conveying direction of the license plate conveyor belt device 100 on the upper side of the license plate conveyor belt device 100, and a receiving conveyor belt device 300 is respectively arranged at the side of the license plate conveyor belt device 100 corresponding to each group of transverse parking devices 200; Generally understood, the conveying direction of the license plate conveyor belt device 100 is from the front side to the rear side. The semi-finished motor vehicle license plates are placed flat on the license plate conveyor belt of the license plate conveyor belt device 100 in a direction perpendicular to the conveying direction of the license plate conveyor belt device 100. The transverse parking device 200 picks up the semi-finished motor vehicle license plates conveyed by the license plate conveyor belt device 100 and conveys the picked-up semi-finished motor vehicle license plates to the receiving conveyor belt device 300 on the side of the license plate conveyor belt device 100, and the receiving conveyor belt device 300 conveys the semi-finished motor vehicle license plates to the endorsing machine.

[0022] Specifically, as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, the transverse parking device 200 includes a mounting frame 210 fixed on the upper side of the license plate conveyor belt device 100, a material taking mechanism 230, a parking conveyor belt mechanism 220, a material supporting mechanism, a positioning baffle 251 arranged in sequence along the conveying direction of the license plate conveyor belt device 100 on the mounting frame 210, and a material pushing mechanism 260 arranged corresponding to the material supporting mechanism for pushing materials to the receiving conveyor belt device 300. The conveying direction of the parking conveyor belt mechanism 220 is set in the same direction as the conveying direction of the license plate conveyor belt device 100; Among them, the parking conveyor belt mechanism 220 includes a front parking belt roller 221, a rear parking belt roller 222 arranged at intervals along the conveying direction of the license plate conveyor belt device 100, and a parking conveyor belt arranged between the front parking belt roller 221 and the rear parking belt roller 222. The front parking belt roller 221 and the rear parking belt roller 222 are respectively rotatably installed on the mounting frame 210; The material taking mechanism 230 includes a material taking rotating shaft 231 rotatably installed on the mounting frame 210, a turning driving mechanism for driving the material taking rotating shaft 231 to rotate, and two rocker arms 232 arranged at intervals along the axial direction of the material taking rotating shaft 231.

[0023] During operation, the flip driving mechanism drives the material taking rotating shaft 231 to rotate, thereby driving the two rocker arms 232 to flip downward, so that the first ends of the two rocker arms 232 flip to the lower parts of the two side edges of the number plate conveyor belt of the number plate conveyor belt device 100, forming an inclined conveying channel. Since the semi-finished motor vehicle number plate is placed flat on the number plate conveyor belt of the number plate conveyor belt device 100 along the conveying direction perpendicular to the number plate conveyor belt device 100, when the number plate conveyor belt device 100 conveys the semi-finished motor vehicle number plate to the first ends of the two rocker arms 232, under the pushing action of the number plate conveyor belt of the number plate conveyor belt device 100 and the material taking conveyor belt 235 of the two rocker arms 232, the semi-finished motor vehicle number plate moves upward along the inclined conveying channel formed by the two rocker arms 232, so that the semi-finished motor vehicle number plate conveyed by the number plate conveyor belt device 100 is picked up, and the picked up motor vehicle number plate semi-finished product is conveyed to the parking conveyor belt mechanism 22 by the material taking conveyor belt 235 of the two rocker arms 232. 0's parking conveyor belt, and then the parking conveyor belt of the parking conveyor belt mechanism 220 transports the picked up motor vehicle license plate semi-finished product to the supporting mechanism and is blocked and positioned by the positioning baffle 251, and then the material shifting mechanism 260 shifts the picked up motor vehicle license plate semi-finished product to the receiving conveyor belt device 300 on the corresponding side, and the receiving conveyor belt device 300 transports the picked up motor vehicle license plate semi-finished product to the signing machine; when the motor vehicle license plate semi-finished product is not needed, the flipping drive mechanism drives the material taking shaft 231 to rotate, thereby driving the two rocker arms 232 to flip upward, so that the first ends of the two rocker arms 232 are lifted, which will not affect the license plate conveyor belt device 100 to transport the motor vehicle license plate semi-finished product backward, can improve the transportation efficiency, and thus improve the production efficiency of the motor vehicle license plate semi-finished product, the motor vehicle license plate intelligent parking material sorting equipment of the embodiment of the present invention solves the problem of low efficiency in transporting motor vehicle license plate semi-finished products to the signing machine, and can improve the production efficiency of motor vehicle license plate semi-finished products.

The semi-finished motor vehicle license plate is placed across the first conveyor belt mechanism 120, the middle conveyor belt mechanism 140, and the second conveyor belt mechanism 130, which can make the semi-finished motor vehicle license plate move smoothly.

Of course, the front tensioning roller and the rear tensioning roller can also be arranged as solid roller body structures, and then they need to be rotatably installed on the lower side of the support rod.
