Example Embodiment

[0047] Example 1:

[0048] Aiming at the defects of manual inspection and traditional lamp inspection system, the present invention abandons the idea of ​​single-frame image inspection. The present invention designs a rotating emergency stop detection device, which can make the medicine bottle rotate at a high speed and then stop suddenly, so as to make the bottle inside The liquid and the impurities that may exist in the liquid rotate, and the difference in time and space between the moving and stationary objects in the sequence image is used to distinguish the interference of the bottle body from the foreign body inside the liquid, which overcomes the influence caused by the interference of the bottle body, and finally analyzed by computer The software signals whether the product is qualified.

[0049] The main part of the device of the invention is figure 1 As shown, it mainly includes: a bottle grabbing manipulator, an electric drive unit, an image acquisition and processing d...

Abstract

The invention discloses a method and equipment for the visual detection of visible foreign matters in a bottled liquid medicine. The method comprises the following steps of: (1) obtaining a multi-frame continuous image from a current liquid medicine which is to be detected and is filled in a medicine bottle by using an industrial camera; (2) preprocessing the image: carrying out top-hat morphologic filtering on the obtained image by adopting a 7*7 circular template as a structural element; (3) extracting a moving object; (4) tracking the moving object; and (5) identifying and judging the image. The device comprises a bottle grabbing manipulator used for grabbing the medicine bottle and an image collecting and processing device arranged close to the bottle grabbing manipulator. The method and the device are suitable for detecting the visible foreign matters of a traditional small-capacity bottled liquid medicine and have the advantages of simple realization, good detection effect, high safety and reliability, extensive application range and the like.

Description

technical field [0001] The invention belongs to the field of industrial machine vision detection, and relates to a method and equipment for visual detection of visible foreign objects in bottled liquid medicines. Background technique [0002] At present, injections, oral liquids, eye drops, etc., which are widely used in our country, are usually filled in the form of glass or plastic bottles. During the production process of these products, due to poor filtration, poor cleaning of containers, and collisions during packaging, etc. , there may be visible foreign matter such as glass shavings, suspended matter, and hair in the liquid. In order to detect whether visible foreign matter is mixed in the filled liquid, it is necessary to perform a visible foreign matter detection for each bottle of medicine. For liquid medicines, since 1985, the Pharmacopoeia of my country has stipulated the testing of clarity and insoluble particles for the testing of such medicines, and strictly c...
