Description

Technical Field

[0001] The invention relates to the field of label screening, and in particular to a defective product screening system for anti-counterfeiting labels. Background Art

[0002] Anti-counterfeiting labels are also called anti-counterfeiting marks or anti-counterfeiting stickers. They can be pasted, printed, or transferred on the surface of the subject matter, or on the packaging of the subject matter, or on the subject matter's accessories (such as product tags, business cards, and anti-counterfeiting certificates). Existing anti-counterfeiting labels partially record product information in the form of QR codes, which is convenient for users to detect through mobile phones; however, the existing inspection method is manual sampling inspection, and manual inspection of labels on different batches of products is inefficient. It is impossible to inspect all products, which easily leads to problems such as the label content not matching the product or the label content not being clear. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention proposes a defective product screening system for anti-counterfeiting labels.
