[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 3 The utility model relates to a device for identifying quality defects of quail eggs, comprising a conveyor belt 1, on which egg racks 4 are arranged at equal intervals. The arrangement spacing of the egg racks 4 can be determined according to actual needs, such as Figure 4 As shown, the egg rack 4 has a horizontally arranged bottom plate 41 and an inclined top plate 42, a support frame 44 is connected between the bottom plate 41 and the top plate 42, and an egg placement hole 43 is opened on the top plate 42 for vertically placing quail eggs. When the quail eggs are placed in the egg placement hole 43, at least 2 / 3 of the quail eggs are exposed;

[0024] A slide 2 is provided on one side of the conveyor belt 1, the inclination direction of the top plate 42 is the same as the direction of the slide 2, and the inner wall of the slide 2 is coupled with a flexible material such as rubber, sponge, cotton, silicone, etc.

[0025] A visual recognition device 3 is also installed on the top surface of the conveyor belt 1. The visual recognition device 3 has an outer shell 31 that is connected to the conveyor belt 1 for the quail eggs to pass through, and the top opening of the slide 2 is placed in the outer shell 31. The inner top of the outer shell 31 is provided with an arc-shaped dome light source 32. A number of LED lamp beads are evenly distributed on the inner arc surface of the dome light source 32. The irradiation direction of the LED lamp beads is just focused on the quail eggs placed on the egg rack 4, so as to achieve all-round irradiation of the exposed part of the quail eggs, so as to reduce the generation of shadows and improve the clarity and recognition accuracy of the taken pictures. At the same time, the inner dome Camera devices 33 are provided at the four corners below the top light source 32 for taking 360° photos of the exposed parts of the placed quail eggs. A linear drive component 34 is installed on the back of the outer shell 31, and its output end passes through the outer shell 31 and is connected to a top egg plate 35. The driving direction of the linear drive component 34 is exactly perpendicular to the longitudinal midline of the top opening of the slide 2. The linear drive component 34 can be a pneumatic rod, a hydraulic rod, an electric push rod, etc. In this embodiment, an electric push rod is preferably used. The protruding end of the top egg plate 35 is an inclined structure, and its inclination angle is the same as that of the top plate 42.

[0026] Among them, the visual recognition device 3 is communicatively connected to an external computer, and the external computer has a GPU and a CPU that are communicatively connected to each other and multiple communication interfaces respectively connected to the CPU. Some or all of the communication interfaces are respectively connected to the dome light source 32, each camera device 33 and a linear drive component 34, which are used to control the operation of each component and receive the captured image data. The CPU multi-threaded application receives the image stream captured by each camera device 33, and performs smoothing and denoising pre-processing on each direction image, and uses color information or grayscale information to separate the image from the background. The segmented image is then binarized to finally extract edge points, area, roundness and other information, and then judge and identify each pixel point one by one to identify dirty eggs, broken eggs, and cracked eggs;

[0027] After identifying defective eggs, Figure 5 As shown, the external computer automatically controls the linear drive component 34 to operate and extend the egg lifting plate 35. After the egg lifting plate 35 is extended, its inclined surface just fits the bottom surface of the top plate 42, so that the defective egg is pushed out from the egg placement hole 43 and slides out through the slide 2. In order to better and stably slide the defective egg out of the slide 2, a guide plate 5 can be symmetrically arranged on the edge of the inclined surface of the top plate 42, as shown in FIG. Figure 4 As shown, it is used to limit the sliding direction of quail eggs.

[0028] Finally, it should be noted that the above description is merely 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 will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
