Automatic proofreading system and method for cigarette packaging two-dimension codes

The invention discloses an automatic proofreading system and method for cigarette packaging two-dimension codes. The automatic proofreading system comprises a two-dimension code generation unit, a two-dimension code printing unit, a data storage unit, a two-dimension code scanning verifying unit, a small box detecting point and a strip box detecting point; the two-dimension code scanning verifying unit is connected with a server through an interchanger; the two-dimension code scanning verifying unit comprises a main detecting machine, the main detecting machine is connected with a coder, an electric eye, a main camera and a waste removing signal box, and the waste removing signal box is connected with a waste removing device; and the coder, the electric eye, the main camera, the coder and the waste removing device are sequentially arranged along a cigarette packaging conveying belt. Generation, printing and detecting of the two-dimension codes are integrated, so that the detecting speed of the cigarette packaging two-dimension codes reaches 400 boxes per minute, the detecting efficiency and the detecting validity are improved, and the manpower cost is saved.
