CCD label detecting machineTechnical Field
The invention relates to the technical field of label detection, in particular to a CCD label detection machine.
Background
For the label, it is attached to the web prior to attachment to the product. The labels on the material tape with the labels attached thereto need to be detected in order to reject the rejected labels.
