[0002] The production process of license plates includes the stamping of license plate numbers, oil film hot stamping of prominent characters on the license plates, and rubbing of characters to obtain the finished license plates. The stamping of prominent characters on license plates is generally done with a dedicated license plate embossing machine. When the number needs to be stamped, the license plate mold and the license plate iron sheet are placed in a position corresponding to the position of the stamping mechanism. The stamping mechanism impacts the mold and the license plate iron sheet to complete the pressing of the license plate numbers. In order to ensure the consistency of license plate styles, facilitate on-site law enforcement on the road to detect counterfeit license plates, and improve the efficiency of road law enforcement, a dedicated anti-counterfeiting license plate mold produced and issued in a unified manner is generally used to ensure the consistency and safety of the license plate. The anti-counterfeiting license plate mold consists of a special anti-counterfeiting QR code and corresponding numbers. Before leaving the factory, the anti-counterfeiting license plate mold needs to be scanned, photographed, and archived to facilitate the subsequent effective management and tracking of each anti-counterfeiting license plate mold. At present, the archiving and storage of anti-counterfeit license plate molds is mainly done by manually holding the corresponding QR code recognition scanning equipment to scan and take pictures of the anti-counterfeit license plate molds, and then uploading them to the corresponding storage module for storage. Due to the use of manual shooting and recording, there will be problems with unclear photos, so it is necessary to take multiple photos and select a clear photo to save. The whole process is cumbersome; and, since the number of license plate molds produced by license plate mold manufacturers is large every day, the workload of workers is large.
