[0001] The utility model relates to the technical field of anti-counterfeiting label recognition, in particular to a recognition device for printing variable characters on an anti-counterfeiting label. Background Art

[0002] Printing variable characters on anti-counterfeiting labels usually refers to printing variable information on the label to increase the anti-counterfeiting effect. These variable characters can be product-related information such as serial number, production date, batch number, etc. By adding variable characters to anti-counterfeiting label printing, the anti-counterfeiting level of the product can be improved, helping companies and consumers to effectively distinguish genuine products, protect consumer rights and interests, and maintain brand image.

[0003] Existing recognition devices are sensitive to lighting conditions when recognizing variable characters printed on anti-counterfeiting labels. If the ambient light is unstable or too strong, it may affect the image acquisition and recognition effects, thereby reducing the recognition quality of the variable characters. For some soft plastic packaging items (such as potato chip packaging bags), the anti-counterfeiting labels on their surfaces may be uneven or reflective when scanned, which may cause interference to the image obtained by the optical recognition module, affecting the recognition quality of the variable characters.
