Specific embodiments

[0036] The following will further elaborate on the content of the present utility model in conjunction with specific embodiments:

[0037] As Figures 1 - 3As shown in the figure, a dinner plate detection module includes a frame 2, a light source 1, a first conveyor belt 3, a detection module 4, a transplanting module 5, a handling module 6, and a transfer module 7. The frame 2 is composed of an upper frame 21 and a lower frame 22, which is used to provide support. Among them, the upper frame 21 is a semi-enclosed structure, and the light source 1 is arranged on the upper frame 21 and illuminates downward, reducing the influence of the external environment during detection, further ensuring sufficient illumination, improving the stability of detection. The detection module 4 includes a detection board 41 and a camera assembly 44. The first conveyor belt 3 transports the dinner plate to a position where the transplanting module 5 can pick it up. The transplanting module 5 moves the dinner plate to the corresponding front detection area 42 or back detection area 43 on the detection board 41, and the camera assembly 44 detects the dinner plate. Subsequently, the handling module 6 moves the dinner plate in the front detection area 42 or back detection area 43 to the back detection area 43 or front detection area 42, and then detects it through the camera assembly 44. The transfer module 7 moves the detected dinner plate out of the detection board 41.

[0038] In this embodiment, the transfer module 7 includes a second conveyor belt 71, a third conveyor belt 72, and a manipulator 73. The second conveyor belt 71 and the third conveyor belt 72 are both fixedly arranged on the lower frame 22. The manipulator 73 moves the dinner plate that has completed detection and is qualified to the third conveyor belt 72, and moves the dinner plate that has completed detection but is unqualified to the second conveyor belt 71. The second conveyor belt 71 rotates to transport the unqualified dinner plate into the waste box 11. Specifically, the transport directions of the second conveyor belt 71 and the third conveyor belt 72 are opposite, which can better distinguish the qualified and unqualified dinner plates.

[0039] As Figures 5 - 7 shown, the transplanting module 5, the handling module 6, and the manipulator 73 move the dinner plate by, but not limited to, grasping, clamping jaws, or suction cups, etc. Preferably, the suction cup method is adopted to use vacuum adsorption to move the dinner plate. The suction cup 13 can firmly adhere to the bottom of the dinner plate, ensuring that the dinner plate will not shake or tilt during movement, effectively preventing the dinner plate from accidentally slipping or falling during movement, thereby improving the detection accuracy and not interrupting the close cooperation between each module, and improving the detection efficiency.

[0040] Furthermore, as Figure 1 、 Figure 5 、 Figure 6 shown, the cooperation between the first conveyor belt 3 and the transplanting module 5 and the handling module 6 can quickly move the dinner plate to the corresponding front detection area 42 and back detection area 43. At the same time, the camera assembly 44 quickly takes pictures of the dinner plate moved to the detection board 41. The transplanting module 5 and the handling module 6 can quickly respond when moving the dinner plate, and quickly move back and forth between the corresponding initial position and termination position, without affecting the real-time photographing of the camera assembly 44 and causing errors or misjudgments due to poor shooting quality.

[0041] As Figure 2As shown, the camera assembly 44 includes two groups of cameras 441 and a placement plate 442, which respectively detect the upper and lower ends of the dinner plate; the dinner plate is placed upside down on the detection plate 41. Among them, the detection plate 41 is a glass plate. The cameras 441 and the placement plate 442 correspond to the front detection area 42 and the back detection area 43. When in the front detection area 42, the cameras 441 are below the detection plate 41, and the placement plate 442 is above the detection plate 41. The cameras 441 take pictures of the front of the dinner plate through the detection plate 41. The placement plate 442 can provide a unified background, which helps to reduce background interference and clutter factors, making the dinner plate more prominent in the photo, facilitating subsequent image processing and analysis. At the same time, the placement plate 442 can also reduce the influence caused by the reflection on the glass surface, help control the propagation direction and intensity of light, help eliminate or reduce the influence from the lower light source 1, make the illumination more uniform and stable, and is conducive to obtaining clear images. When in the back detection area 43, the cameras 441 are above the detection plate 41, and the placement plate 442 is below the detection plate 41. The cameras 441 take pictures of the back of the dinner plate. Further, the orthographic projection of the dinner plate on the detection plate 41 is within the shooting range of the cameras 441 taking pictures of the detection plate 41, facilitating the overall shooting of the dinner plate without causing some areas of the dinner plate to not be photographed, reducing the detection accuracy.

[0042] In another embodiment, the dinner plate is placed upright on the detection plate 41. When in the front detection area 42, the cameras 441 are above the detection plate 41, and the placement plate 442 is below the detection plate 41. The cameras 441 take pictures of the front of the dinner plate. When in the back detection area 43, the cameras 441 are below the detection plate 41, and the placement plate 442 is above the detection plate 41. The cameras take pictures of the dinner plate through the detection plate 41.

[0043] As Figure 2 As shown, light source assemblies 8 are respectively arranged on the four sides of the lower frame 22. Through the light source assemblies 8 arranged on the four sides of the lower frame 22, it is ensured that the dinner plate can be evenly illuminated at different angles and positions, which can reduce background interference, help reduce shadows and reflections, and improve the quality and clarity of the image. And the uniform illumination can improve the stability of imaging. At the same time, the uniform illumination of the light source assemblies 8 can reduce the brightness difference during camera shooting, making the captured image more stable and reliable. Cameras 9 are arranged on two light source assemblies 8 on the short sides of the lower frame 22, and cameras 10 are arranged on two light source assemblies 8 on the long sides of the lower frame 22. The two cameras 9 are on the same straight line as the dinner plate. The two cameras 10 respectively correspond to the front detection area 42 and the back detection area 43. The cameras 9 and 10 are used to detect the shape and size of the dinner plate, detect the clarity and integrity of the edges and contours of the dinner plate, facilitate the discovery of any damage or cracks, and ensure that the dinner plate has no defects.

[0044] Further, as Figure 3 and Figure 4 shown, photoelectric sensors 12 are provided on both sides of the second belt line 71. When a non-conforming dinner plate moves along the second belt line 71 and passes through the photoelectric sensor 12, the light emitted by the photoelectric sensor 12 is reflected or partially blocked, and then the blocked or reflected light is received by the photoelectric sensor 12 and converted into an electrical signal. After the electrical signal is processed and analyzed, it can detect whether a dinner plate has passed by; an emergency stop button 14 is arranged on the side of the upper frame 21, and the button 14 is pressed in an emergency to stop the system.

[0045] The implementation principle of the embodiment of the present application:

[0046] The first belt line 3 transports the dinner plates to be detected into the frame 2. When the dinner plate moves to the end of the first belt line 3, the transplanting module 5 adsorbs the dinner plate through the suction cup 13 and moves it to the front detection area 42 on the detection plate 41. At this time, the light source 1 provides illumination, and the upper frame 2 and multiple light source components 8 cooperate to make the light source sufficient and not affected by the external environment. The corresponding first camera 441 takes a picture of the front of the dinner plate through the detection plate 41. Under the action of the placement plate 442, the picture taken by the first camera 441 is clearer. At the same time, two second cameras 9 and two third cameras 10 take pictures of the sides of the dinner plate. Subsequently, the handling module 6 adsorbs the suction cup through the suction cup 13 and moves it to the reverse detection area 43, and the corresponding first camera 441 takes a picture of the reverse side of the dinner plate. The pictures taken by the two first cameras 441, the second cameras 9, and the third cameras 10 are transmitted to the processor for analysis. When the dinner plate is non-conforming, the manipulator 73 places the suction cup on the second belt line 71, and the second belt line 71 moves the dinner plate into the waste box 11. When passing through the photoelectric sensor 12, the photoelectric sensor 12 detects whether a dinner plate has passed by through the change of light. When the dinner plate is qualified, the manipulator 73 places the suction cup on the third belt line 72 for transmission and use.
