Machine vision-based product packaging detection system

Abstract

The present invention discloses a machine vision-based product packaging detection system. The system comprises a support protection mechanism, and a belt transmission mechanism, a sensing mechanism,a position correction mechanism, an image collection mechanism and a defective product recovery mechanism that are connected with the support protection mechanism. The sensing mechanism, the positioncorrection mechanism, the image collection mechanism and the defective product recovery mechanism are respectively arranged on both sides of the belt transmission mechanism; the belt transmission mechanism is horizontally arranged in the middle of the support protection mechanism; each mechanism is respectively connected with a motion control card; and the motion control card is connected with a PC component. According to the system disclosed by the present invention, the industrial camera and the computer software detection method used in the system are more accurate than the manual visual inspection, so that the detection precision is effectively improved; a unified detection standard is established, so that the subjective difference existing in the manual detection is eliminated, and the system has high efficiency, and can adapt to various production environments; and the machine vision can achieve non-destructive detection during the detection process, so that hidden dangers of defects after detection are eliminated.

Description

technical field [0001] The invention belongs to the technical field of machine vision detection, in particular to a product packaging detection system based on machine vision. Background technique [0002] As an integral part of the product, packaging can not only show the function and value of the product, but also affect the overall image of the product. Beautiful and flawless packaging can enhance consumers' trust in product quality, while products with defective packaging will reduce the overall competitiveness of the product. Under the condition of the same quality, those products with good packaging quality and neat appearance are more popular among consumers. In the food, drug, wine, cosmetics and other industries, the impact of product packaging on product quality and sales is particularly obvious. Packaging Testing has also become an indispensable part of controlling packaging quality in the production process of products. In the automatic production line of produ...

Problems solved by technology

[0003] The existing product packaging inspection method based on machine vision is mainly to detect defects on one side of a fixed product packaging. Even if there are multiple sides, the robot is used to flip the product to be inspected. In the process, the camera is used to take pictures. Non-destructive testing cannot be realized, so there is no effective solution for non-destructive defect detection of different products or multiple surfaces at the same time
