[0002] During the production process of motor vehicle license plates, it is necessary to sign a QR code on the semi-finished motor vehicle license plate as the identification serial number of the semi-finished motor vehicle license plate. The signing operation is completed by laser printing on the semi-finished motor vehicle license plate by a signing machine.

[0003] At present, semi-finished motor vehicle license plate products are transported by conveyor belts.
