Description

Technical Field

[0001] The utility model relates to the field of trademark label quality inspection, in particular to a double-vision inspection device for inspecting the double-sided appearance quality of labels. Background Art

[0002] In the sale of products, it is usually necessary to stick, hang or sew corresponding labels on the products. The labels are printed with information about the product. As the product's selling point, the appearance and materials of the labels also require merchants to carefully consider.

[0003] After the label is produced, the pattern and appearance printed on the label need to be inspected to prevent defective labels from entering the market. Most labels on the market are of two types, one is a single-sided printed label, and the other is a double-sided printed label. The double-sided printed label needs to be inspected on both sides to avoid problems such as pattern ghosting and incomplete printing. During the inspection, in order to improve the efficiency of label inspection, the material strip composed of multiple labels connected end to end is inspected.

[0004] However, existing label detection equipment can only detect the pattern on the front side of the label tape in a single detection. After the front side of a batch of labels is detected, when it is necessary to detect the pattern on the back side of the label, the batch of label tapes is flipped over and the back side of the label tape is detected, which greatly reduces the detection efficiency.
