Description

Medicine bottle vision detection device with multi-color light source

Technical Field

The utility model relates to a medicine bottle surface defect detection device, in particular to a medicine bottle visual detection device with a multi-color light source, which can adapt to medicine bottles with different colors, namely deep and shallow medicine bottles, and can effectively detect the surface defects of bottle mouths.

Background

Along with the increasing attention of society to the medicine field, the use amount of various plastic medicine bottles is also increasing, and simultaneously, the customer is higher to the requirement of plastic medicine bottle quality, and this has put forward higher requirement to medicine bottle enterprise's production and quality inspection, in order to reach above-mentioned finished product quality requirement, medicine bottle manufacturing enterprise adopts constantly to increase manual monitoring dynamics, increases the quality inspection number promptly and carries out deeper training realization to the quality inspection personnel.

Specifically, after the plastic medicine bottle is produced, various defects such as high-low bottle, special-shaped bottle, heterochromatic bottle, half-cut bottle, bottle opening upper edge damage, bottle opening outer edge damage, bottle opening lower edge damage, side wall dirt burst, bottle bottom dirt foreign matter, bottle bottom transparent film, bottle bottom damage, bottle body and bottle opening form and position tolerance can occur under the influence of original equipment, raw materials and various production factors. At present, the problem of missed detection and false detection easily occurs in the visual detection of human eyes, so that the yield of the cost always has a certain problem.

Among the above defects, such as abnormal color, abnormal shape and obvious damage can be detected by using an industrial camera, but for the defects of the concave and convex plane of the bottle mouth, the defects are difficult to detect by a single industrial camera and a single light source, and in particular, the concave or convex of the bottle mouth has an influence on the sealing property of the medicine bottle, so that the defects are not allowed in the qualification standards of most medicine bottles, and the inspection of the bottle mouth is time-consuming and labor-consuming at present by means of manual inspection, and is easy to miss.

Although corresponding medicine bottle detection devices appear in the industry, the concave or convex of the bottle mouth, particularly the concave and convex of uniform arc transition, cannot be detected frequently, so that the medicine bottle passing through the medicine bottle detection device cannot be reliably ensured at the bottle mouth part. The above problems occur because the existing medicine bottle detection device is mainly implemented by using a single light source and a single industrial camera to detect a single plane, and a plane image is obtained, and for the plane image, the detection mainly uses the color difference of different areas of the image to judge defects or foreign matters, but for the pure flat appearance of concave and convex, the difference is not seen in plane, and the plane image cannot be identified.

In view of the foregoing, there is a need in the art for a device for detecting such irregularities in a vial finish.
