[0023] The following further describes the embodiments of the invention in detail with reference to the accompanying drawings of the specification, so as to more clearly present the purpose, technical solution and technical effect of the present invention.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0025] Such as Figures 1-5As shown in the figure, the utility model discloses a sea duck egg crack detection device, which includes a detection mechanism, a conveying table 1 and a bearing tray 5. The detection mechanism is arranged on the conveying table 1. The bearing tray 5 can be placed on the conveying table 1 and is driven by the conveying table 1 for conveying. The bearing tray 5 is used for bearing sea duck eggs. The detection mechanism includes a first detection module 2, a second detection module 3, a vacuum suction cup assembly 4 and a control unit. The first detection module 2 is located directly above the conveying channel of the conveying table 1 and is used for sampling the sea duck eggs on the bearing tray 5 from directly above. The second detection module 3 is located below the conveying channel of the conveying table 1 and is used for sampling the sea duck eggs on the bearing tray 5 from directly below. The first detection module 2 and the second detection module 3 are arranged alternately. The vacuum suction cup assembly 4 is arranged directly above the conveying channel of the conveying table 1 and corresponds to the second detection module 3. The vacuum suction cup assembly 4 includes a lifting frame 9, a support plate 10 and vacuum suction cups 11. The lifting frame 9 is fixed on the conveying table 1, and one end of the lifting frame 9 is fixed with the support plate 10. The vacuum suction cups 11 are arranged on the support plate 10, and the vacuum suction cups 11 correspond to the sea duck eggs on the corresponding bearing tray 5 one by one. An LED lamp 12 is arranged inside the vacuum suction cup 11. A sampling hole 8 is arranged in the middle of the bearing tray 5 for the second detection module 3 to sample the sea duck eggs on the vacuum suction cup assembly 4 through the sampling hole 8. The control unit is respectively connected to control the first detection module 2, the second detection module 3, the lifting frame 9 and the LED lamp 12.

[0026] The above uses the first detection module 2 and the second detection module 3 located directly above and directly below the conveying channel of the conveying table 1 to sample the sea duck eggs from different directions. The alternating arrangement of the two can achieve comprehensive detection. The vacuum suction cup assembly 4 is used to adsorb and fix the sea duck eggs, and the internal LED lamp 12 provides auxiliary lighting for convenient detection. The sampling hole 8 and the bottom through hole 7 of the bearing tray 5 are helpful for the detection of the second detection module 3. The travel switch controls the start and stop of the conveying table 1 to ensure that the bearing tray 5 accurately stops at the detection station. The lifting assembly drives the second detection module 3 to rise close to or pass through the sampling hole 8 for better detection. The shielding frame 13 prevents external light from affecting the detection result. The electromagnetic control valve controls the working state of the vacuum suction cup 11. The opaque bearing tray 5 avoids light interference, and the symmetrically arranged conveying chain ensures the stable conveying of the bearing tray 5.

[0027] Among them, in order to detect the sea duck eggs more clearly and accurately, both the first detection module 2 and the second detection module 3 adopt high-definition sampling cameras. This makes the sampling images clearer and the details more abundant, improving the accuracy and reliability of crack detection. Further, in order to reduce the interference of external light on the detection result, shielding frames 13 are arranged at the positions of the conveying table 1 corresponding to the first detection module 2 and the second detection module 3. This makes the detection environment more stable and the detection result more reliable.

[0028] Here, in order to ensure that the bearing tray 5 can accurately stop at the detection station for sampling, travel switches are provided at the corresponding positions of the conveyor table 1 for the first detection module 2 and the second detection module 3. This makes the detection process more stable and orderly, and avoids detection errors caused by inaccurate conveying positions.

[0029] In order to enable the second detection module 3 to better detect the sea duck eggs, the second detection module 3 is connected to the conveyor table 1 through a lifting component. In this way, when the bearing tray 5 docks above the second detection module 3, the second detection module 3 can flexibly rise close to or pass through the sampling hole 8, improving the comprehensiveness and accuracy of the detection.

[0030] In order to improve the detection efficiency and quantity, the bearing tray 5 is provided with a plurality of bearing positions 6 for bearing the sea duck eggs, and through holes 7 for light transmission are provided at the bottoms of the bearing positions 6. This enables multiple sea duck eggs to be detected simultaneously, and the through holes 7 contribute to light penetration for the purpose of detection.

[0031] In order to more precisely control the working state of the vacuum suction cup 11, electromagnetic control valves are provided on the vacuum pipelines of the vacuum suction cup 11, and the electromagnetic control valves are connected to the control unit. This makes the adsorption and release of the sea duck eggs more flexible and controllable, improving the accuracy and efficiency of the detection operation.

[0032] In order to avoid the influence of external light on the detection, the bearing tray 5 is made of light-proof material. This makes the detection process not interfered by external light, and the detection results are more accurate and reliable.

[0033] In order to ensure the smoothness of the conveyance of the bearing tray 5, the conveyor table 1 includes two symmetrically arranged conveyor chains, and both ends of the bearing tray 5 are connected to the conveyor chains. This makes the bearing tray 5 more stable during the conveyance process, reducing the detection errors caused by shaking.

[0034] Based on the above structure, the operation steps of the present utility model include:

[0035] (1) Place the sea duck eggs on the bearing tray 5.

[0036] (2) Place both ends of the bearing tray 5 on the conveyance channel of the conveyor table 1, start the conveyor table 1, and drive the bearing tray 5 to start rotating.

[0037] (3) When the bearing tray 5 rotates to below the first detection module 2, the travel switch at the corresponding position of the conveyor table 1 is triggered, causing the conveyor table 1 to stop running, and the bearing tray 5 can stop at the corresponding station. At this time, the first detection module 2, that is, the high-definition sampling camera, located directly above the conveyance channel of the conveyor table 1, will take pictures and sample the sea duck eggs on the bearing tray 5 from directly above. It should be clear here that it is necessary in the prior art to provide a lighting device below the bearing tray 5 to cooperate with the picture-taking and sampling, which will not be elaborated here.

[0038] (4) The control module controls the conveyor table 1 to continue running. When the carrier tray 5 rotates to below the second detection module 3, the travel switch is triggered again, causing the conveyor table 1 to stop, and the carrier tray 5 stops at the corresponding work station again. After the carrier tray 5 is in place, the control module controls the operation of the vacuum suction cup assembly 4, that is, controls the vacuum suction cup 11 to descend and adsorb the column of sea duck eggs, and then raises it through the lifting frame 9 to facilitate sampling by the second detection module 3. The lifting assembly drives the second detection module 3 to rise, approach or pass through the sampling hole 8 in the middle of the carrier tray 5, and sample the sea duck eggs from directly below.

[0039] (5) The control module obtains the sea duck eggs with cracks and their positions on the carrier tray 5 based on the first detection module 2 and the second detection module 3, and finally selects them by a manipulator or manually.

[0040] Here, both the first detection module 2 and the second detection module 3 obtain high-definition images to facilitate the control module to determine whether there are cracks based on the images. Existing crack analysis algorithms can be used here. Through the settings of the vacuum suction cup assembly 4, the second detection module 3 and the sampling hole 8 in the middle of the carrier tray 5, the sea duck eggs are turned over for shooting to realize the crack analysis of the entire shell of the sea duck eggs. Compared with the existing method of flipping sea duck eggs by a conveyor belt, the present utility model can ensure that the crack analysis of the entire shell of the sea duck eggs is carried out without dead angles, improving the reliability.

[0041] In sea duck egg processing enterprises, the device of the present utility model can be integrated into the production line to realize the automatic crack detection of sea duck eggs.

[0042] The above are only the preferred and feasible embodiments of the present invention, and are not used to limit the scope of the patent application of the present invention. All equivalent changes, equivalent substitutions or modified changes completed within the technical spirit and principles disclosed by the present invention should be included within the scope of patent protection covered by the present invention.
