Problems solved by technology

However, since the bottle clamping device is composed of two parts, it is very likely that the bottle will be broken when the bottle moves, and the rotating device only drives a part of the clamping device to move. When the bottle rotates at a high speed, the center line of the rotation It may shake, causing the liquid in the bottle to generate a lot of air bubbles. The existence of the air bubbles will greatly reduce the detection quality and increase the false detection rate

Embodiment 1

[0048] Aiming at the defects of manual detection and traditional light inspection system, the present invention abandons the idea of ​​single-frame image detection. The present invention designs a rotating emergency stop detection device, which can make the medicine bottle rotate at high speed and then stop suddenly, so that the inside of the bottle The liquid and the impurities that may exist in the liquid rotate, using the difference in time and space between the moving and stationary objects in the sequence image to distinguish the bottle body interference from the foreign matter inside the liquid, overcoming the influence of the bottle body interference, and finally through computer analysis The software gives a signal whether the product is acceptable or not.

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

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, highsafety 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...
