Detailed Description
The present invention will be further explained with reference to the accompanying drawings:
as shown in fig. 1, the bottled liquid detection optical system comprises a grid 4, a camera 1, a lens 2 and a light source 5, wherein the light source 5 is arranged below the grid 4, the light source 5 is a flat light source, and the light source 5 is a backlight source and plays a role of the backlight source. The top of grid 4 is equipped with bottled liquid 3, the top of bottled liquid 3 is equipped with camera lens 2, the top of camera lens 2 is connected with camera 4, camera 1 is connected with the computer, 2 orientation bottled liquid 3 of camera lens. The lens 2 can be vertically towards the bottled liquid 3, and can also be inclined at a certain angle, so long as the lens 2 can meet the shooting requirement towards the bottled liquid 3.
Fig. 4 shows one embodiment of the present invention, the light source 5, the bottled liquid 3, the grid 4, the camera 1 and the lens 2 are sequentially arranged from top to bottom, the lens 2 faces the bottled liquid 3, the camera 1 can shoot the lower part of the bottled liquid 3, and the lens 2 can face the bottled liquid 3 vertically or be inclined at a certain angle.
Fig. 5 shows one embodiment of the present invention, the light source 5, the bottled liquid 3, the grid 4, the camera 1 and the lens 2 are sequentially arranged from left to right, the lens 2 faces the bottled liquid 3, the camera 1 can shoot the bottled liquid 3 from the side, and the lens 2 can face the bottled liquid 3 vertically or be inclined at a certain angle (as shown in fig. 6).
The shape of the grid 4 can be made into various shapes according to actual needs, for example: elongated (as shown in fig. 1), circular (as shown in fig. 3), square, diamond, hexagonal, etc.
The method comprises the following steps that bottled liquid 3 to be detected reaches a detection area through a conveying line, a grid 4 is arranged above a light source 5, the light source 5 irradiates the bottled liquid in the detection area, light emitted by the light source 5 is reflected by the grid and directly irradiates a product, the bottled liquid 3 to be detected is uniformly irradiated, the stability of image shooting is realized, a camera 1 shoots the product, and when no grid backlight source directly irradiates the bottled liquid 3, as shown in fig. 2, the image shot by the camera 1 is fuzzy light color; after the grid is added, as shown in fig. 3, the camera 1 can shoot a clear image, which is convenient for the computer to analyze and identify the foreign matters in the liquid. The camera 1 shoots and transmits the images to a computer for processing and analysis, the computer identifies all the characteristics of the foreign matters in the bottled liquid, and then the characteristics of the foreign matters in the bottled liquid are compared with standard images, and the foreign matters are judged to be defective products through analysis of the characteristics of the contents.
