A self-adhesive smart label defect detection device and its sensing detection method

Abstract

This invention relates to the field of label defect detection technology, specifically to a self-adhesive intelligent label defect detection device and its sensing detection method, including a base and a detection module and guide roller assembly mounted on the base. The guide roller assembly includes a first guide roller and a second guide roller mounted within the base. The first guide roller is connected to two second elastic telescopic rods mounted within the base, and each second elastic telescopic rod is equipped with an intelligent pressure sensor for monitoring the tension of the label width. This effectively eliminates wrinkles caused by increased tension in the label width, avoiding the problem that the detection module cannot accurately identify label defects due to the presence of wrinkles. Through a follow-up mechanism, the position of the slider can be automatically adjusted according to the tension of the label width, so that the slope angle formed by the first tilting arm and the second tilting arm is adaptively adjusted, thereby achieving intelligent matching between the tension of the label width by the assembly frame and the current tension of the label width.
