Embodiment approach

[0050] See image 3 , The present invention uses the side rear reflector, the second prism and the second camera group to form the back side of the bottom light to detect the light path of the foreign object in the side and rear of the detection bottle. It is installed on the side and rear of the detection bottle 1 The reflecting mirror synchronously reflects the light that can form the rear image of the bottle to the second prism 3. The second prism 3 is installed directly above the first prism and is tilted at a slight angle relative to the first prism to form a secondary reflection of the image , The side and rear information detected by the bottom light is transmitted to the second camera group installed above the first camera group.

[0051] See Figure 4 In another embodiment, the detection device and detection method are the same as the above, but the additional mirror 5 is placed at the original position where the first, second, and third cameras are placed, and the direct...

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 invention relates to a detection method for bottled liquid foreign matter based on a reflection light path design, and also relates to a detection device for detecting foreign matter in a bottled liquid by adopting the method, which can be mainly used in various bottled liquids, especially medical bottled liquids such as infusion bottles. Foreign body detection belongs to the field of detection technology. Background technique [0002] Medical infusion bottles have very high requirements for the cleanliness of the liquid in the bottle, but due to the production process or production environment and other reasons, the infusion product may be mixed with glass, aluminum, rubber, hair, fiber, or insoluble drugs and other small foreign objects . These foreign bodies are small in size and may enter the human body with the infusion during intravenous infusion, causing blockage of blood vessels, causing cysts, and seriously endangering the life and health of p...
