Automatic detection device based on machine vision for defects of instant noodle sauce packets and method

Abstract

The invention belongs to the technical field of automatic detection, and relates to an automatic detection device based on machine vision for defects of instant noodle sauce packets, which is used for detecting whether packaged continuous sauce packets have defects or not. The continuous sauce packets are clamped by sauce packet clamps and conveyed by a sauce packet conveying line arranged on a support, the detection device comprises an in-place sensor, a camera, a light source and a controller. The in-place sensor is fixed onto the support and used for perceiving the tact of motion of the conveying line, signals outputted by the in-place sensor are transmitted into the controller, the controller triggers the camera to take photos according to the perception signals of the in-place sensor, the photos taken by the camera are transmitted into a computer, and processed and analyzed by the computer, and the computer judges whether the sauce packets have defects or not and transmits results to the controller. The invention simultaneously provides a method for detecting defects of instant noodle sauce packets by the aid of the device. The automatic detection device and the method have the advantages that the shortcoming of interference of subjective factors in a manual visual inspection method is completely overcome, existence and quantity completeness of the sauce packets can be quickly, objectively and accurately detected, and detection precision and efficiency for the quality of products are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of automatic detection, in particular to a device for automatic detection of defects in instant noodle sauce packets. technical background [0002] With the intensification of global economic integration, the food and drug industry has higher and higher requirements for product quality, forcing companies and enterprises in related industries to invest more human and financial resources in product quality inspection. In the packaging process of instant noodles, the package integrity of instant noodles is an important aspect to measure product quality. The hygienic hazards of instant noodle products due to the defect of instant noodle sauce wrapping will not only cause complaints and claims from customers after they enter the market, but also bring unpredictable reputation and economic losses to the manufacturer, directly affecting the market image of the manufacturer. At the same time, it also harms the inte...

Problems solved by technology

However, in the process of packaging, due to a certain probability of delay in the extrusion and packaging mechanism, the packaging between the two bags of sauce is not complete, so that they are connected through, so that the connected sauce packets are cut into individual sauces. When it is packaged, it will cause the phenomenon of sauce flow, and the food hygiene situation cannot be guaranteed

The manual detection method is convenient, intuitive, and has high accuracy, but it is greatly affected by subjective factors, and the workers' work intensity is high. Long-term work is easy to cause visual fatigue, judgment errors, and affect product quality inspection; and when the packaging line speed is too fast , the operator is basically unable to complete the detection
