[0032] The following further elaborates on the content of the present utility model in conjunction with specific embodiments:

[0033] As Figures 1 - 5As shown in the figure, an automatic loading and unloading machine for detecting defects of an environmentally friendly lunch box includes a frame 1, a first conveyor belt 2, a second conveyor belt 3, a lifting and transplanting module 4, a first detection module 5, a lifting and flipping module 6, a third conveyor belt 7, and a manipulator 10; the two second conveyor belts 3 are located on both sides of the first conveyor belt 2, and the lifting and transplanting module 4 moves back and forth between the first conveyor belt 2 and the second conveyor belt 3 to move the dinner plate from the second conveyor belt 3 to the first conveyor belt 2; the first detection module 5 includes a light bar 51, a light bar angle adjustment seat 52, and a first camera 53. A plurality of light bar angle adjustment seats 52 are installed on the frame 1 through brackets and are distributed at intervals around the vertical axis where the first camera 53 is located. A plurality of light bars 51 are correspondingly installed on the light bar angle adjustment seats 52, and the inner sides are inclined towards the surface of the first conveyor belt 2. During use, the angle of the light bar angle adjustment seat 52 can be adjusted according to the outdoor environment at that time and the required lighting intensity, so as to change the inclination angle of the light bar 51, thereby adapting to the lighting requirements of the current environment, changing the incident direction of the light, helping to illuminate different parts of the object at different angles, controlling the position and intensity of the shadow, thereby reducing or moving the shadow, making the details on the surface of the dinner plate clearer, improving the quality of the captured image, being beneficial to the detection of defects on the surface of the dinner plate. At the same time, by adjusting the angle of the light source, the reflection caused by the light directly irradiating the object surface can be reduced or avoided, improving the clarity and quality of the image, and helping to observe and identify the defects on the dinner plate.

[0034] Furthermore, the surfaces of the first conveyor belt 2, the second conveyor belt 3, and the third conveyor belt 7 are all transparent. When taking pictures, the transparent conveyor belt allows more light to pass through, making the background clearer or achieving a transparent effect, making the captured image clearer. Moreover, the transparent surface usually has less reflection, and the light will not be reflected back by the surface, not causing flash or glare to affect the camera shooting.

[0035] In one embodiment, the dinner plate is placed on the surfaces of two conveyor belts II 3. The dinner plate is moved onto conveyor belt I 2 by the lifting and transplanting module 4 and moves along with conveyor belt I 2. After passing through the first detection module 5, camera I 53 takes a picture of the front of the dinner plate. When the dinner plate moves below the lifting and flipping module 6, the lifting and flipping module 6 adsorbs and flips the dinner plate through the suction cup assembly 11, exposing the back of the dinner plate under camera II 81. Subsequently, camera II 81 takes a picture. Then, the manipulator 10 moves the dinner plate onto conveyor belt III 7. The two second light sources 91 are respectively located above the edges of the dinner plate and are arranged in parallel. Through side illumination, the strip light source can reduce the shadows generated by front illumination, making the details on the surface of the dinner plate more clearly visible, which helps the detection system accurately detect the features and defects of the dinner plate after taking pictures. At the same time, by setting the second light sources 91 at the edges of the dinner plate, the reflection generated due to the direct light irradiation on the surface of the dinner plate is reduced, which can avoid the reflected light from affecting the quality of the captured image, ensuring the clarity and accuracy of the image. Moreover, the strip light source provides side light, which can generate a strong contrast, making the edges and features of the dinner plate more prominent, helping to improve the quality of the image, making the dinner plate more separated from the background, and facilitating subsequent image processing and analysis.

[0036] Further, as Figure 4 shown, the light irradiates the dinner plate from both sides and camera II 81 is located between the two second light sources 91, reducing the possibility of generating shadows and light spots during shooting due to the large distance gap between camera II 81 and the two second light sources 91, thereby generating a more uniform and natural lighting effect, making the contour of the dinner plate more obvious, and helping to improve the recognizability and distinguishability of the defects on the dinner plate.

[0037] As Figure 3 shown, a through hole 83 is provided at the center of the first light source 82. Camera II 81 takes pictures of the dinner plate downward through the through hole 83. Since camera II 81 is located at the center of the first light source 82, the first light source 82 can provide more uniform illumination, enabling the entire product surface to be properly illuminated when camera II 81 takes pictures, which helps to reduce shadows and reflections and improve the image quality and clarity. The orthographic projection of the dinner plate on the suction cup assembly 11 falls within the shooting range of camera II 81 on the suction cup assembly 11, enabling the whole dinner plate to be photographed instead of only photographing part of the dinner plate, which may lead to the inability to accurately detect the defects of the dinner plate. Among them, the lifting and transplanting module 4, the lifting and flipping module 6, and the execution end of the manipulator 10 are all provided with suction cup assemblies 11 for adsorbing the dinner plate and moving the dinner plate to the next position.

[0038] In another embodiment, the dinner plate is buckled on the second conveyor belt 3, and the lifting and transplanting module 4 moves the dinner plate to the first conveyor belt 2. When the dinner plate passes through the third detection module 9, the third camera 92 takes a picture of the reverse side of the dinner plate. When the dinner plate moves to the lower part of the lifting and flipping module 6 along with the first conveyor belt 2, the lifting and flipping module 6 sucks and flips the dinner plate. After flipping, the second camera 81 takes a picture of the front side of the dinner plate. After the picture taking is completed, the manipulator 10 moves the dinner plate to the third conveyor belt 7, and the light bar angle adjustment seat 52 is used to adjust the light bar 51 to a suitable angle, and then the first camera 53 takes a picture.

[0039] For further explanation, the installation positions of the lifting and flipping module 6 and the manipulator 10 can be replaced, and the installation positions of the first detection module 5, the second detection module 8, and the third detection module 9 can be adjusted, as long as it is ensured that during the transportation of the dinner plate on the second conveyor belt 3, the first conveyor belt 2, and the third conveyor belt 7, the first detection module 5, the second detection module 8, and the third detection module 9 can take pictures of the front and reverse sides of the dinner plate.

[0040] The implementation principle of the embodiment of the present application:

[0041] The lifting and transplanting module 4 moves back and forth between the first conveyor belt 2 and the second conveyor belt 3, moving the dinner plate on the second conveyor belt 3 to the first conveyor belt 2. The dinner plate moves along with the first conveyor belt 2, and at the same time, according to the lighting of the surrounding environment, the light bar angle adjustment seat 52 is adjusted to change the angle of the light bar 51. When the dinner plate moves to the lower part of the first detection module 5, the light bar 51 provides lighting from multiple directions, reducing reflection and shadow while enabling the first camera 53 to take clearer and more accurate pictures of the front side of the dinner plate. The dinner plate moves along with the first conveyor belt 2. When it moves to the lower part of the lifting and flipping module 6, the lifting and flipping module 6 adsorbs and flips the dinner plate through the suction cup assembly 11. At this time, the upper second camera 81 takes pictures of the reverse side of the dinner plate through the through hole 83 under the illumination of the first light source 82. Subsequently, the manipulator 10 moves the photographed dinner plate to one end of the third conveyor belt 7, and two second light sources 91 are located above the edge of the dinner plate, making the outline of the dinner plate clearer under the shooting of the third camera 92.
