[0023] ​In the embodiment, the cylindrical lampshade 1 is split into two parts, i.e. the first circular arc lampshade 101 and the second circular arc lampshade 102, which can realize the opening and closing of the cylindrical lampshade 1. When the second circular arc lampshade 102 moves away from the first circular arc lampshade 101, the cylindrical lampshade 1 is opened to form an opening area on the left and right sides, and the bottle to be detected can be translated into the center of the cylindrical lampshade 1 from the opening area on the left side.

The camera 7 can move forward and backward in the strip-shaped mounting groove 23, which is convenient for adjusting the position of the camera during debugging of the detection machine.

[0028] Further, the number of the small windows 5 is four, and the small windows 5 are circumferentially and uniformly distributed on the cylindrical lampshade 1. The coaxial light source 6 and the camera 7 are arranged on each of the four small windows 5. This arrangement can make the four circumferentially and uniformly distributed cameras 7 cover a 360° shooting area, overcoming the defect that the label or pattern on the bottle body is oriented differently when the bottle enters the detection area.

[0029] Working principle: the bottle conveying device 10 is started, the first lifting device 15 is lowered, the electric clamping jaw 20 is lowered and clamped on the bottle mouth of the bottle to be detected, then the first lifting device 15 is raised, the sliding mechanism 9 works to drive the second circular arc lampshade 102 to move away from the first circular arc lampshade 101 to open the cylindrical lampshade 1, the rotary motor 13 works to drive the rotary plate 14 to rotate, the bottle to be detected enters the cylindrical lampshade 1, the sliding mechanism 9 works to drive the second circular arc lampshade 102 to move close to the first circular arc lampshade 101 to close the cylindrical lampshade 1, at this time, the light source lamp 3, the coaxial light source 6 and the camera 7 work to take a picture of the bottle, after the picture is taken, the sliding mechanism 9 works to drive the second circular arc lampshade 102 to move away from the first circular arc lampshade 101, the cylindrical lampshade 1 is opened again, the rotary motor 13 continues to rotate to make the bottle leave the cylindrical lampshade 1.
