Description

Area-array camera and label detection equipment

Technical Field

The utility model relates to a label technical field, concretely relates to area array camera and label check out test set.

Background

The area-array camera can be used for collecting images in a certain area, identifying the measurement of the area, shape, temperature and the like of an object in a target area, and plays an important imaging role in the prior art.

Labels are indispensable parts of goods, and can be used to indicate names, purposes, instructions, and the like of objects. Some articles are relatively small and therefore require a relatively small area of label to be applied. However, batch printing has some defective products due to the small area of the label. Such as incomplete identification information, fuzzy text or pattern, wrong label and missing label. And the sale and use of the articles can be influenced under the conditions that some anti-counterfeiting marks or national standard marks are not clear and the like.

Therefore, after the labels are printed in batches, the images and texts on the labels need to be detected before the labels are attached and used or before the labels are shipped. The finished label is printed on a label tape which is rolled and released.

In the prior art, detection is performed for a label on a label tape. The detection process is to roll up the label band, and in the rolling process, whether the labels on the label band are qualified or not is checked one by one.

However, both manual inspection and image recognition inspection have the following problems:

1) the label band has certain rolling speed, and the label band still can continue to move in the manual work or the process of image identification contrast screening. Thus, the tape has moved a distance during inspection of the label after it is seen or picked. When the label is found to be unqualified, the label band is braked, the stopped label is not on the current inspection station, the label detection process has hysteresis, and when a large number of labels exist on the label band, the position of the unqualified label is difficult to position;

2) in order to improve the detection speed of the label tape, the unwinding and winding speeds of the label tape can be improved, and the manual identification speed is difficult to improve at the same time;

3) when the running speed of the label tape is higher, the label tape can be braked immediately and continuously moves for a certain distance under the action of self inertia, so that the unqualified label moves along with the label tape, and the difficulty in positioning the unqualified label is increased.

The image and the first time information of the label passing through the first detection unit are collected, and the second time information is recorded when the comparison result shows that the label is an unqualified product. The metering unit can record the moving distance of the label belt at any moment, and can be understood as recording the moving distance of the label at each moment when the distances among the labels are uniformly distributed on the label belt.
