DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Embodiment 1

[0022] Please see attached Figure 1 - Attachment Figure 4 A high-precision fully automated valve label position detection device includes a frame 1 and a detection mechanism 4. The detection mechanism 4 includes a collection processor 401, a position sensor 404 and a mounting frame 405. A zoom lens 402 and a fill light 403 are fixedly mounted on the surface of the collection processor 401. An opening 407 is passed through the middle of the surface of the mounting frame 405. The opening 407 is connected to a forward and reverse motor 408 and a steering plate 410 through a rotating shaft 409. A controller 3 is provided on the front of the frame 1. A conveyor belt 2 is provided inside the frame 1. The bottom of the collection processor 401 is fixedly mounted on the upper surface of the frame 1 near the middle of the front. The fill light 403 is along the zoom lens 402. The lenses 402 are distributed in a circle, the bottom of the position sensor 404 is fixedly mounted on the upper surface of the frame 1 near the left side of the back, the bottom of the mounting frame 405 is fixedly mounted on the upper surface of the frame 1, baffles 406 are fixedly mounted on both sides of one end of the mounting frame 405, the forward and reverse motor 408 is fixedly mounted in the middle of the upper surface of the mounting frame 405, one end of the rotating shaft 409 is fixedly mounted on the output end of the forward and reverse motor 408, the steering plate 410 is fixedly mounted on the other end of the rotating shaft 409, and the rotating shaft 409 is rotatably connected to the inside of the opening 407, and the acquisition processor 401, the position sensor 404 and the controller 3 are connected through PLC control.

[0023] After detecting that a valve has passed, the position sensor 404 sends a signal to the acquisition processor 401 for photo processing. The distance between the acquisition processor 401 and the valve can be shortened by adjusting the zoom lens 402. The forward and reverse motor 408 rotates to drive the steering plate 410 to adjust the same angle. The valve will move along the offset angle of the steering plate 410. The baffle 406 will complete the angle correction before the valve enters the collection box to prevent the valve from slipping out and falling.

[0024] Specifically, the position sensor 404 detects the position of the valve, triggers the acquisition processor 401 to work, ensures that the shooting is done at the right time, adjusts the focal length and image quality through the zoom lens 402, and provides suitable, uniform and stable lighting conditions for shooting through the fill light 403 to ensure that the image is clear and accurate, and realizes the rotation of the steering plate 410 through the forward and reverse rotation of the forward and reverse motor 408, and cooperates with the acquisition processor 401 to classify the identified valves into genuine and defective products for quick and convenient classification. Embodiment 2

[0025] Please see attached Figure 1 , Attachment Figure 2 , Attachment Figure 5 and attached Figure 6 , and on the basis of Example 1, it is further obtained that a cleaning mechanism 5 is arranged on the upper left side of the frame 1, and the cleaning mechanism 5 includes a cleaning frame 501 and a fixing block 504, the cleaning frame 501 is fixedly installed on the upper surface of the frame 1 near the left side of the front, a cleaning motor 502 is fixedly installed at one end of the cleaning frame 501, a cleaning roller brush 503 is fixedly installed on the outer wall of the output end of the cleaning motor 502, the internal thread of the fixing block 504 is connected with a threaded member 505, and the inner end of the threaded member 505 is sleeved with a limiting plate 506.

[0026] The rotation direction of the cleaning motor 502 is opposite to the transmission direction of the conveyor belt 2, so that the cleaning roller brush 503 can effectively clean the obstructions on the valve. The limit plate 506 and the threaded member 505 are socketed to ensure that the limit plate 506 will only move and not rotate while the threaded member 505 rotates, thereby pushing the valve so that the valve label is against the cleaning roller brush 503.

[0027] Specifically, by rotating the threaded part 505, the limit plate 506 can be brought close to the side of the valve without a label, and the side of the valve with a label can be brought close to the cleaning roller brush 503. Before testing, the cleaning roller brush 503 is driven to rotate by the cleaning motor 502 to clean the obstructions on the valve label to avoid affecting subsequent testing.

[0028] Working principle of the utility model: The utility model is a high-precision fully automated valve label position detection device. The valve to be detected is placed on the left end of the conveyor belt 2, and then the limit plate 506 is pushed close to the side of the valve without a label by rotating the threaded member 505 in the fixed block 504, and the side of the valve with a label is close to the cleaning roller brush 503. Then the conveyor belt 2 is turned on, and the cleaning roller brush 503 is driven to rotate by the cleaning motor 502 before detection to clean the obstructions on the valve label. After the cleaned valve passes through the position sensor 404, a signal is sent to the acquisition processor 401 for photo processing, which can be adjusted by adjusting the zoom lens 402. The distance between the acquisition processor 401 and the valve is shortened, and the fill light 403 is used to provide suitable, uniform and stable lighting conditions for shooting to ensure that the image is clear and accurate. When the detection result shows that the valve label position is incorrect, the forward and reverse motors 408 rotate clockwise, causing the steering plate 410 to rotate clockwise, and the valve slides along the direction of the steering plate 410 and eventually falls into the defective collection box. When the detection result shows that the valve label position is correct, the forward and reverse motors 408 rotate counterclockwise, causing the steering plate 410 to rotate counterclockwise, and the valve slides along the direction of the steering plate 410 and eventually falls into the genuine collection box, thereby completing the detection of the valve label position.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
