System and method for detecting bar code quality

Abstract

The invention discloses a system and a method for detecting bar code quality. The system comprises a conveying device, a bar code detection device, a system control device and a product distinguish device, wherein the conveying device is used for conveying a plurality of products to be detected; the bar code detection device is used for colleting bar code information when the products to be detected pass below the bar code detection device; the system control device is used for receiving the bar code information, comparing the bar code information with accurate bar code information stored in the system control device and generating a judgment result; and the product distinguish device is used for distinguish the products to be detected according to control signals of the system control device. The method and the system can recognize and distinguish products printed with incorrect bar code information out of the plurality of products fast and accurately so as to ensure the unique correspondence between the bar code information and the product.

Description

technical field [0001] The present invention relates to the field of printing technology, and more specifically, the present invention relates to a system and method for detecting barcodes and rejecting waste products. Background technique [0002] At present, when printing companies use inkjet printing equipment to print barcodes, due to factors such as mechanical equipment failures and inkjet printing equipment failures, products that need to print barcodes often have missing printing, wrong printing, reprinting, and multiple printing. mistake. Among them, missing printing means that there is no barcode printed at the position where the barcode should be printed; misprinting means that the printed barcode information is incorrect; reprinting means that the printed barcode information is the same as the barcode information on a certain product; Refers to the situation where two or more barcodes are printed on one product. If the above-mentioned errors occur, the product q...
