Detailed Implementation

[0017] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0018] A device for detecting the cleanliness of plates used in a smart canteen, such as Figures 1-4 As shown, the device includes a base 1, a first mounting bracket 2, a distance sensor 3, a second mounting bracket 4, a cylinder 6, a guide rod 7, a CCD camera 9, a conveyor belt 10, and a control panel 11. The conveyor belt 10 is located on the inner side of the top of the base 1. The first mounting bracket 2 is located on the top of the base 1. The distance sensor 3 is located at the bottom of the first mounting bracket 2. The cylinder 6 is located on the front side of the base 1. The second mounting bracket 4 is connected to the telescopic rod of the cylinder 6. A connecting block is located on the rear side of the base 1. The guide rod 7 is located on the top of the connecting block. The top of the guide rod 7 is slidably connected to the second mounting bracket 4. The CCD camera 9 is located at the bottom of the second mounting bracket 4. The control panel 11 is located on the front side of the base 1. The distance sensor 3 and the cylinder 6 are both electrically connected to the control panel 11.

[0019] like Figure 4 As shown, it also includes a connecting plate 12 and an exposure lamp 13. The conveyor belt 10 is a transparent belt. The connecting plate 12 is provided on the inner side of the base 1. The exposure lamp 13 is provided on the connecting plate 12. The exposure lamp 13 adopts an adjustable brightness LED light source, which can adjust the light intensity according to the different materials or colors of the plates, thereby improving the image contrast and recognition effect. The exposure lamp 13 is located inside the conveyor belt 10. The exposure lamp 13 provides uniform backlight to the CCD camera 9 through the transparent conveyor belt 10, further improving the contrast of the plate image and the detection clarity.

[0020] like Figure 3 As shown, it also includes a light-shielding tube 5. The CCD camera 9 is provided with a light-shielding tube 5 on its outside. The light-shielding tube 5 is used to shield the ambient light interference and improve the detection accuracy of the CCD camera 9 for the plate.

[0021] like Figure 3 As shown, it also includes a ring light 8. The ring light 8 is located at the bottom of the light shield 5. The ring light 8 provides uniform front lighting, enhances the display of details on the surface of the plate, and enhances image quality.

[0022] like Figure 1 As shown, it also includes an alarm 14. The alarm 14 is located on the front side of the base 1. Both the CCD camera 9 and the alarm 14 are electrically connected to the control panel 11. When the plate passes through the detection area, the CCD camera 9 will capture the image of the plate surface. The control panel 11 will then determine whether the plate is clean according to preset parameters. If the detection result shows that the plate has stains, residues, or other conditions that do not meet the cleaning standards, the control panel 11 will activate the alarm 14 and remind the canteen staff to pay attention through an audible signal.

[0023] In use, canteen staff place the trays on the conveyor belt 10. The distance sensor 3 monitors the height of the trays in real time and feeds back the detected data to the control panel 11. Based on the tray height fed back by the distance sensor 3, the control panel 11 calculates the vertical position that the CCD camera 9 needs to be adjusted, controls the telescopic rod of the cylinder 6 to push the second mounting bracket 4 up and down, and drives the CCD camera 9 up and down to adjust the relative distance between the CCD camera 9 and the tray, so that the CCD camera 9 can detect trays of different heights.

[0024] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
