Bottled liquid foreign body detection method and detection device based on reflected optical path design

Abstract

The invention relates to a detection method for detecting foreign matters in bottled liquid based on a reflected light path design and a detection device adopting the method. According to the method, a mechanical hand is used for clamping a detection bottle containing liquid from the upper part of the detection bottle to perform bottom light detection and backlight detection; a bottom light source is used for illuminating the detection bottle from the downside of the detection bottle to the upside; a first camera is used for shooting a transmittance image of front surface bottom light reflected by a first prism; a second camera is used for shooting a transmittance image of back surface bottom light which is reflected by a side back reflecting mirror and then reflected by a second prism; a backlight source is used for illuminating the detection bottle from the back surface of the detection bottle; a third camera is used for shooting a transmittance image of backlight reflected by a third prism; the images are analyzed to determine whether foreign matters exist in the liquid in the bottle; and the detection device consists of the light sources, the prisms, the reflecting mirrors, the cameras and matching devices. The detection device disclosed by the invention is small in volume and high in detection efficiency, and can be mainly used for detecting foreign matters in various bottled liquids especially medical bottled liquids including infusion bottles and the like.

Description

technical field [0001] The present invention relates to a method for detecting foreign objects in bottled liquids based on reflection optical path design, and also relates to a detection device for detecting foreign objects in bottled liquids using the method, which can be mainly used for various bottled liquids, especially infusion bottles and other medical bottled liquids. The foreign matter detection belongs to the technical field of detection. Background technique [0002] Medical infusion bottles have very high requirements on the cleanliness of the liquid in the bottle, but due to the production process or production environment, the finished infusion may be mixed with tiny foreign objects such as glass chips, aluminum chips, rubber chips, hair, fibers or insoluble drugs . These foreign bodies are small in particle size, and may enter the human body along with the infusion during intravenous infusion, causing blood vessel blockage and cysts, which seriously endanger t...

Problems solved by technology

The advantage of this method is that the infusion bottle does not stop, and the bottle moves quickly; the disadvantage is that the camera group swings back and forth with the infusion bottle for a long time. The cable is loose and worn, causing the camera to lose power or the captured image cannot be transmitted to the processing host, and the equipment fails and shuts down
