The product detection assembly 3 comprises a high-speed camera 4 and an image analyzer, wherein the high-speed camera 4 is used for collecting paper product images on the conveying belt and sending the paper product images to the image analyzer, and the image analyzer is used for judging the quality of the collected paper product images. It can be understood that, firstly, a standard comparison image corresponding to the product 8 to be detected is input into the image analyzer, in the operation process of the detection device, the image of the product 8 to be detected on the paper on the conveyor belt is acquired in real time through the high-speed camera 4, the image is sent to the image analyzer to be compared with the standard comparison image in error, and the quality detection result of the corresponding paper product is calculated according to a preset error threshold value. In a specific embodiment, the detection result can be classified into a qualified product and an unqualified product according to a preset threshold, and can also be classified into four quality grades of high quality, good quality, medium quality and poor quality. When analyzing the quality of the product, the analysis mainly includes analyzing the shape defect and the color defect of the product. The shape defects mainly refer to flaws, foreign matters, stains, knife threads and the like. The method is characterized in that the difference between the gray value of the defect position of the defect image and the standard image on the image is represented, the gray value of the defect image is compared with the standard image, whether the difference value exceeds the preset threshold range or not is judged, and whether the image has the shape defect or not can be judged. The color defect mainly means that the color of the image of the product to be detected is different from that of the image of the standard product. According to the set standard template, the printing defects generated in the printed product, such as character pasting, missing printing, dirty points, ink points, burrs, overprinting deviation, gold stamping deviation, die cutting deviation, poor striping, color difference and the like, can be effectively detected.
And the sorting controller sorts the corresponding paper products into corresponding sorting channels according to the quality analysis result of the paper products by the image analyzer. In the embodiment of the invention, as a preferable scheme, the number of the sorting channels can be 2, namely, a qualified product channel and an unqualified product channel, when the image analyzer judges the conveyed product as a qualified product, the sorting controller sorts the product into the qualified product channel, and so on, thereby completing continuous automatic detection and sorting of the paper product, and greatly improving the production efficiency in the production process.
