when the light-transmitting foreign matters and the light-proof foreign matters are detected simultaneously, the background plate 2 is adjusted to be gray, so that a part of light emitted by the light source 1 is scattered to the background plate 2 and then reflected to the bottle body 3 through the background plate 2, and the bottle body 3 forms a low backlight effect, so that the light-transmitting foreign matters are lighter than the background, and the light-proof foreign matters are darker than the background;
when the foreign matter is colored, the color of the background plate 2 is changed to be opposite to the color system of the foreign matter, and the characteristic of the foreign matter is highlighted.
The invention has the specific working principle that:
as shown in fig. 1, the light source 1 is a bar light source, the side surface is a background plate 2, the background plate 2 can present different colors (usually white and black), the bar light source and the background plate are fixed by a bracket, and the light emitting direction of the light source 1 forms an angle of 90 degrees with the liquid level direction, forming a light source system. The middle is a bottle 3 to be detected, and the right is a camera 4 for acquiring an image of the sample.
The background plate of the light source system may be electronic. Through software control, multiple image taking modes such as white background plate acquisition, black and white background plate alternate acquisition and the like can be realized in the detection process, the image taking modes can be freely switched, the characteristic of foreign matters can be better captured, and the foreign matters can be more accurately distinguished and detected.
When the background plate is white, as shown in fig. 1 and 3, two light beams are irradiated on the bottle 4, the light beam directly emitted from the light source 1 to the bottle 4 is formed by the light source scattering, and the other part of the light is formed by the light source 1 scattering to the background plate 2 and then reflecting through the background plate. At the moment, the two parts of beams are combined together, the effect is equivalent to backlight, the foreign matter imaging is darker than the background, the bottle bottom has no blind area, and meanwhile, the imaging effect of the fine object is superior to that of the common backlight, so that the finer foreign matter can be detected;
when the background plate is black, as shown in fig. 2 and 4, the light source 1 irradiates the black background plate to be absorbed, and only the scattered light beam of the light source 1 directly irradiates the bottle 4. At the moment, the light source system is equivalent to bottom light, foreign matter imaging is brighter to the background, compared with a common low-light source, the light source of the system is positioned below the liquid level, the illumination range is wider, the peripheral illumination is uniform, the image interference is less, the misjudgment rate is reduced, the illumination area is increased, the blind area is reduced, and the omission factor is reduced;
when the background plate is gray, the light source system is equivalent to the combination of backlight and low light, the imaging of the light-transmitting foreign matters is brighter than that of the background, the imaging of the light-proof foreign matters is darker than that of the background, and the system can detect the light-transmitting foreign matters and the light-proof foreign matters simultaneously;
when waiting to examine article when having the colour, can be through the colour that changes the background board, the salient foreign matter characteristic satisfies different sample detection demands.
The light source background board also can be mechanical type, and a set system disposes the card formula background board of multiple colour, and when the user detected different solvents, it can to change the card that corresponds the colour: use white card when detecting dark color foreign matter, use black card when detecting light color foreign matter.
