[0024] Please see Figures 1-4 In this embodiment of the utility model, a poultry egg screening device includes a carrying component 1, on which a separating transmission component 2, a robotic arm 3, a visual detection component 4, a bad egg collection component 5, and a backlight screening component 6 are configured.

[0025] The carrier component 1 includes a carrier box 11. Two brackets 12 are symmetrically fixedly connected to the rear side of the carrier box 11 to provide sliding support for the bad egg collection component 5. A transmission groove 13 is opened on the front side of the top of the carrier box 11 to accommodate the separation transmission component 2. A support base 14 is fixedly connected to the bottom of the carrier box 11 to ensure the overall stability of the device.

[0026] The separation and transmission component 2 includes a transmission belt 21 disposed in the transmission trough 13, which can drive the poultry eggs forward; a number of partition plates 22 are fixedly connected at equal intervals on the transmission belt 21, which can separate and limit the poultry eggs to avoid stacking and shifting during transmission.

[0027] The robotic arm 3 is symmetrically fixedly installed on the rear side of the top of the carrier box 11, which can accurately grab poultry eggs and transfer them to different work stations.

[0028] The visual inspection component 4 includes an L-shaped connecting frame 41, which is fixedly connected to the carrier box 11 to provide installation support for the image acquisition module 42; and the image acquisition module 42 is fixedly installed on the L-shaped connecting frame 41 to acquire images of the appearance of poultry eggs to identify surface defects.

[0029] The bad egg collection component 5 includes a collection box 51. The bottom wall of the collection box 51 has several egg placement slots 52, which can be used to position bad eggs and avoid collision damage. A handle 53 is fixedly connected to the rear end of the collection box 51, which makes it easy for the operator to pull the collection box 51. The bottom sides of the collection box 51 have bracket fitting slots 54 that are adapted to slide and engage with the bracket 12, so that the collection box 51 can slide smoothly along the bracket 12 and is easy to pick up and put down.

[0030] The backlight screening component 6 includes a backlight module 61 and a control console 62. The backlight module 61 is fixedly installed at the bottom of the transmission trough 13 and directly below the transmission belt 21, and can emit uniform backlight. The control console 62 is fixedly installed at the front center of the carrier box 11 and is used to integrate control commands. The control console 62 is connected to the backlight module 61 through a control line 63 to realize the power supply and control of the backlight module 61.

[0031] The separator 22 is made of plastic and has a certain degree of elasticity to avoid damaging the eggs. The spacing between two adjacent separators 22 is adapted to the size of a single egg, ensuring that only one egg is transferred at a time.

[0032] The image acquisition module 42 covers the area above the conveyor belt 21 and is used to collect appearance image information of poultry eggs, providing a data basis for subsequent defect identification.

[0033] The shape of the egg placement slot 52 is adapted to the shape of the poultry egg, which can limit and fix the bad eggs. The egg placement slot 52 is distributed in an array in the collection box 51, which can collect multiple bad eggs at one time and improve collection efficiency.

[0034] The backlight module 61 is equipped with a uniform backlight lamp at the top, which can emit uniform backlight. The conveyor belt 21 is a light-transmitting belt, which allows light to pass through the eggs on the conveyor belt 21, making it easier to detect whether there is any deterioration or blood streaks inside the eggs, thus improving the comprehensiveness of bad egg identification.

[0035] The control console 62 is electrically connected to the conveyor belt 21, the image acquisition module 42 (the specific model can be referred to as the industrial camera module MV-CA050-10GM), the robotic arm 3 (the specific model can be referred to as the JAKA Zu12 series), and the backlight module 61, and is used to control the operation of each component to realize the automated collaborative work of the device.

[0036] The image acquisition module 42 is the core of the "visual inspection component 4". It needs to work with the backlight module 61 to achieve dual detection of "appearance defects + internal defects of poultry eggs". The workflow is divided into two steps: "hardware acquisition" and "data transmission and analysis". First, the control console 62 starts the backlight module 61 through the control line 63. The uniform backlight lamp at the top of the module emits stable light. After the light passes through the "light-transmitting conveyor belt 21", it shines on the poultry eggs on the conveyor belt. At this time, if there is deterioration inside the poultry egg (such as broken yolk) or blood streaks, it will form obvious "light and shadow differences" (the light transmission is uniform in the undefected poultry eggs, and the light transmission is reduced in the defective areas). At the same time, the image acquisition module 42 (including optical lens and image sensor) fixed by the L-shaped connecting bracket 41 is started. The camera is aimed at the eggs above the conveyor belt 21. The image sensor converts the "appearance of the eggs (such as cracks and stains on the eggshell) + internal image after backlight penetration" into electrical signals. The signal processing chip built into the module processes the electrical signals into "digital image data", and then transmits them to the control console 62 through a data cable (such as a gigabit network cable or a USB cable). The shooting range of the data collaboration (defect recognition basis) image acquisition module 42 needs to "completely cover the area above the conveyor belt 21", and the partition plate 22 ensures that "only one egg is transmitted at a time" - which means that the module acquires "a complete image of a single egg" each time, avoiding the overlap of multiple egg images, and providing a clear and single data source for the subsequent "defect algorithm recognition" of the control console 62.

[0037] The core of robotic arm 3 is "receiving commands from the control panel → accurately grabbing bad eggs → transferring them to the collection component." It needs to work in conjunction with conveyor belt 21, image acquisition module 42, and control panel 62. The specific process is as follows: robotic arm 3 is electrically connected to control panel 62 via a data cable. Control panel 62 will first preset "two key coordinates": ① "coordinates of the egg to be grabbed" on the conveyor belt (located by image data from image acquisition module 42, for example, calculating its real-time position on the conveyor belt after identifying a bad egg); ② "coordinates of the egg placement slot 52" in the bad egg collection component 5 (preset fixed position, such as the slot number in the array distribution); when control panel 62 identifies "a certain egg as bad" through image analysis, it will send a "grabbing command" to robotic arm 3. The robotic arm's drive system (such as servo motors and reducers) drives the joint movement, causing the end gripper (or suction cup) to move to the "coordinates of the bad egg on the conveyor belt"—its repeatability (such as ±0.02mm) ensures that the gripper can accurately align with the egg and avoid deviation.

[0038] The grasping execution principle (anti-breakage + stable transfer) typically involves a "flexible gripper" (such as plastic / silicone material) or a "negative pressure suction cup" at the end of the robotic arm. If a gripper is used, it adjusts its opening and closing angle according to the size of the egg (the gripper stroke is preset to match the diameter of the egg), gently clamping the egg (the gripper pressure is preset by the control console to avoid crushing the eggshell). If a suction cup is used, it uses negative pressure to adhere to the surface of the egg, similarly avoiding contact damage. After grasping a bad egg, the robotic arm moves along a preset trajectory to the coordinates of the "egg placement slot 52", the gripper releases (or the suction cup depressurizes), and the bad egg is smoothly placed into the slot (the slot shape is adapted to the egg to further avoid collision). After grasping, the robotic arm resets to the "standby position" to wait for the next grasping command from the control console, realizing "continuous automated screening".

[0039] The load-bearing box 11 is made of stainless steel, which has good corrosion resistance and structural strength. The outer surface of the load-bearing box 11 is coated with an anti-rust coating, which further extends the service life of the device.

[0040] The working principle of this utility model is as follows: When in use, the poultry eggs are placed on the conveyor belt 21, and the separator 22 separates and limits the poultry eggs. The conveyor belt 21 moves the poultry eggs toward the vision detection component 4. The image acquisition module 42 acquires the appearance image of the poultry eggs and transmits it to the control console 62. At the same time, the backlight module 61 emits uniform light, which shines through the light-transmitting conveyor belt 21 to illuminate the poultry eggs, making it easier to detect the internal condition. The control console 62 analyzes the image data. If it is identified as a bad egg, it controls the robotic arm 3 to grab the poultry egg and transfer it to the egg placement slot 52 of the bad egg collection component 5. When a certain number of bad eggs are collected, the operator pulls out the collection box 51 along the bracket 12 using the handle 53 to complete the centralized processing of bad eggs. Qualified poultry eggs continue to be transported to the next process with the conveyor belt 21.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
