Description

Technical Field

[0001] The present invention relates to the technical field of wine bottle detection, and more particularly to a device for detecting and rejecting empty wine bottles. Background Art

[0002] Wine bottles are containers for alcoholic beverages, usually made of glass, ceramic, plastic or other materials. Wine bottles have different designs and shapes, not only to meet practical functions, but also to pursue beauty and brand image display. Wine bottles are commonly green glass bottles, but also brown or other colors, to protect beer from light, and have good sealing to prevent alcohol volatilization and oxidation. During the production and processing of wine bottles, detection equipment is needed to detect them to remove defective bottles.

[0003] A comparative patent with publication number CN202379377U mentions a wine bottle defect detection device, but its detection device is just a simple conveyor belt enhanced light, so there are still the following problems and shortcomings: defect detection still relies on manual naked eye detection, with low detection efficiency and poor detection accuracy. Wine bottles are only transported by conveyor belts, and defective wine bottles detected are not rejected;

[0004] A comparative patent published as CN114048789A mentions wine bottle defect detection based on improved Cascade R-CNN, but this device only describes the use of the improved Cascade R-CNN algorithm for wine bottle defect detection, which has the following problems and shortcomings: the detection algorithm is single, and the requirements for wine bottle defect detection are different for different manufacturers, so different algorithms or different versions of the same algorithm need to be provided for users to choose and use. There is only a detection algorithm, but no transmission, defect detection and defective bottle rejection device, so a complete closed loop cannot be formed and it cannot be directly used in production.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present invention provides a device for detecting and rejecting empty wine bottles, which has the following beneficial effects:

[0018] 1. By setting a clamping device, the wine bottle on the upper end of the rotating disk can be clamped and fixed so that it can revolve on the upper end of the rotating disk. At the same time, the motor is turned on to rotate the turntable so that the wine bottle can rotate while revolving, and then the detection camera can take pictures and transmit the data to the detection center to achieve the effect of defect detection. This design eliminates the step of manually inspecting the wine bottle with the naked eye, and this patent has concluded through a large number of experiments and field tests: "Different types of defect detection require different types of light sources". Therefore, this patent uses different forms of light sources for fill light at different workstations, combined with the detection camera and the main shaft turntable to achieve high-speed shooting of empty wine bottles at all angles. After a large number of tests and verifications, multiple types of light sources have improved the detection accuracy by >= 20%. The single-bottle defect detection speed of this patent can reach 160ms / bottle.

[0019] 2. By setting up qualified channels and unqualified channels, the feed turntable can transport the wine bottles to the upper end of the rotating disk. After testing, the discharge turntable will gradually remove the wine bottles, and use the test results of the testing center to determine which bottles are defective and unqualified. Then, the unqualified bottles are pushed to the unqualified channel on the conveyor belt through the rejection push plate to achieve the effect of automatic rejection. This design does not require manual operation and is fully automatic, with a very high rejection accuracy. After a large number of tests, the rejection accuracy of the rejection device is >= 99%.

[0020] 3. This patent adopts multi-algorithm detection and provides related applications of algorithm configuration. On the one hand, the use of multi-algorithm detection can make up for the limitations of single-algorithm detection and improve the accuracy of defect detection. On the other hand, multi-algorithm detection provides users with more and better defect detection algorithm matching solutions, and users can flexibly choose according to their own production needs. After testing in an actual production environment, this patent has a detection accuracy rate of >= 75% for common empty wine bottle defects (scratches, cracks, bubbles, etc.); through feedback from the actual production environment, users are extremely satisfied with the flexible configuration of multiple algorithms, and can configure the algorithm type and detection performance parameters according to the focus of their own detection needs, and the overall adaptability and flexibility of the equipment are improved.
