A detection system and method for plastic ziplock bags

Abstract

The invention discloses a detecting system and a detecting method for a plastic automatic sealing bag. The system comprises a line scanning device, a detecting base, a photoelectric sensor, a blowing device, an electromagnetic valve, a first rolling shaft, a second rolling shaft, a driving motor, a motor driver and an industrial control computer, wherein the detecting base is positioned below the line scanning device; the photoelectric sensor is arranged on the detecting base; the blowing device is used for blowing a plastic automatic sealing bag product to a preset position according to preset procedures; the electromagnetic valve is used for controlling the blowing device to blow or stopping blowing and is electrically connected to the blowing device; the first rolling shaft and the second rolling shaft are respectively arranged on two sides of the detecting base and are used for driving the plastic automatic sealing bag product to move on the detecting base; the motor driver is electrically connected to the driving motor; the industrial control computer is respectively connected to the line scanning device, the electromagnetic valve, the photoelectric sensor and the motor driver. The detecting system disclosed by the invention has the beneficial effects that the qualified rate of the product is improved, the quality risk of an outgoing product is reduced, and the defects of the plastic automatic sealing bag are identified by sufficiently utilizing an image processing and pattern recognition technique.

Description

technical field [0001] The invention relates to the technical field of machine vision image detection and pattern recognition, in particular to a plastic ziplock bag detection system and method. Background technique [0002] In recent years, with the rapid development of image processing and pattern recognition technology, more and more engineering projects use image processing algorithms to solve practical problems, such as dimension measurement, classification and identification of workpiece products, product surface defect detection, license plate number recognition , barcode recognition, etc. Our daily life is inseparable from all kinds of plastic ziplock bags. The black spots and dirt on the plastic ziplock bags will affect the hygiene of the food packaged in the bag, thus affecting our health. The printing on the plastic ziplock bags will be blurred or misaligned It affects the beauty of the ziplock bag itself. The rupture of the plastic ziplock bag can easily lead to...
