DETAILED DESCRIPTION

[0029] Example 1: Reference Figure 1-Figure 7An egg crack detection device includes a mounting frame 1, with conveyor chains 2 provided on both sides of the mounting frame 1, and a plurality of horizontally placed rollers 3 connected between the two conveyor chains 2. It should be noted that the conveyor chain 2 can adopt conventional conveying methods such as chains or conveyor belts to ensure that the rollers 3 can be connected to the conveyor chain 2 and can convey eggs as the conveyor chain 2 moves, and the horizontal extension direction of the rollers 3 is perpendicular to the horizontal movement direction of the conveyor chain 2. A plurality of limiting rollers 4 are installed on the rollers 3, and the outer diameter of the limiting rollers 4 gradually increases from the middle position toward the two ends of the rollers 3, so that the eggs can be placed exactly on the limiting rollers 4 between the adjacent rollers 3. The eggs are placed in the middle so that the eggs move along with the conveyor chain 2 along with the limiting rollers 4 on both sides. The limiting rollers 4 are made of silicone material. A detection component 5 is installed below the roller shaft 3 in the mounting frame 1. The detection component 5 is provided with a probe 8. The bottom end of the probe 8 is connected to a spring 7. A cavity is opened at the bottom of the probe 8. A sound collector 6 is provided in the cavity. A sealing plug 9 is fixed to the outer wall of the sound collector 6. The outer wall of the sealing plug 9 is in sliding contact with the inner wall of the cavity in the middle of the probe 8. The top of the sound collector 6 extends above the sealing plug 9, and the top of the sound collector 6 for collecting sound is located between the outer wall of the top of the sealing plug 9 and the inner wall of the top of the probe 8. The position between the walls, when the egg is moved and transported along with the conveyor chain 2, the roller 3 and the limit roller 4, when the egg moves to the corresponding position of the detection component 5, the bottom of the egg will touch the top of the probe 8 and produce a knock, and the sound of the collision is processed by the sound collector 6 inside the probe 8. The sound signal collected by the sound collector is processed, including pre-processing operations such as amplification and filtering, and then converted into a digital signal, and spectrum analysis is performed to extract the spectrum characteristics of the sound. The extracted sound spectrum characteristics are compared with the sound spectrum data of known cracked and non-cracked eggs to determine whether the egg is cracked. Generally speaking, due to the incompleteness of the internal structure of cracked eggs, more high-frequency components will be generated when colliding, and the sound may decay faster. The detection of the collision sound can effectively avoid the problem of incomplete shooting detection, and can be detected in real time during the egg transmission process, thereby improving detection efficiency. It is suitable for rapid detection on large-scale production lines. Through accurate analysis of the sound spectrum, it is possible to more accurately determine whether the egg is cracked. It should be noted that: based on multiple experiments on placing eggs, the height position of the probe 8 is pre-adjusted so that the egg and the probe 8 can collide slightly and will not be damaged by excessive squeezing force.The design also uses a sealing plug 9 on the outer wall of the sound collector 6 to seal the bottom of the cavity in the probe 8. This seal prevents external air vibrations from affecting the sound collection within the cavity. Furthermore, a silicone limit roller 4 prevents the impact of the egg colliding with other structures on the sound collection. Furthermore, a spring 7 allows the probe 8 to adapt to collisions with eggs of varying states or sizes within a certain range. The friction between the sealing plug 9 and the inner wall of the probe 8 effectively reduces the impact of the probe 8 pressing down or rebounding upward, preventing secondary collisions caused by the probe 8 rapidly rebounding after colliding with the egg. This improves the accuracy of audio data collection, and the overall design ensures the accuracy and effectiveness of detecting egg cracks using collision sound.

[0030] In the present invention, there are multiple detection components 5 in the mounting frame 1, and the multiple detection components 5 are distributed at equal distances. A placement slot is provided between the corresponding limiting rollers 4 on two adjacent rollers 3, and the placement slot is used to place eggs. Multiple detection components 5 will appear at the middle position of the corresponding placement slot at the same time. When the detection component 5 is in the middle position of the placement slot, a placement slot is left between the two adjacent detection components 5 distributed along the extension direction of the roller 3, and a placement slot is left between the two adjacent detection components 5 distributed along the direction of the conveyor chain 2. Through the distribution of the above-mentioned multiple detection components 5, multiple groups of eggs can be placed simultaneously along the extension direction of the roller 3 for conveying and detection, and the same egg can be detected multiple times by multiple detection components 5 in the conveying direction. Multiple detection data are compared multiple times to improve the accuracy of simple surface crack detection; at the same time, in this application, the staggered arrangement of multiple detection components 5 avoids simultaneous collision detection of eggs at adjacent positions in the conveying direction, thereby avoiding mutual influence between sounds, and simultaneous collision of adjacent positions in the extension direction of the roller 3 is also avoided, and the limiting roller 4 made of silicone material in the middle position is used for stabilization, so as to avoid the influence of mechanical vibration of the roller 3 on the sound data collection; thus, the staggered distribution of the above-mentioned multiple detection components 5 effectively improves the accuracy and effectiveness of the audio collected by the detection component 5 at each position after colliding with the egg, and the detection operation of multiple detection components 5 improves the accuracy of single egg detection, and improves the work efficiency of large-scale egg detection.

[0031] In the present invention, a rack 13 is fixed on one side of the mounting frame 1 below the roller 3. The rack 13 extends horizontally in the moving direction of the conveyor chain 2 and is located at one end of the roller 3 in the extending direction. A gear 14 is installed at one end of the outer wall of the roller 3 at a position corresponding to the rack 13. During the process of conveying eggs for inspection, when the roller 3 moves to the inspection area, the gear 14 at the end of the roller 3 will engage with the rack 13 at the fixed position. As the roller 3 moves with the limiting roller 4 and the eggs, the gear 14 engages with the rack 13, causing the roller 3 to rotate with the limiting roller 4 at the same time. The limiting roller 4 is made of silicone material, so that the surface of the egg can be cleaned by the rotation of the limiting roller 4, thereby improving the accuracy of subsequent collision detection. In addition, under the action of friction, the egg may be flipped between the two limiting rollers 4, so that the same egg is subjected to collision detection at different positions when detected by different position detection components 5, thereby further improving the accuracy of detection.

[0032] In the present invention, a dust collection component 10 is provided on one side of the detection component 5 in the mounting frame 1. The dust collection component 10 is located below the roller 3. The conveyor chain 2 moves toward the direction of the corresponding detection component 5 from the dust collection component 10. That is, when the eggs move along the conveyor chain 2, they will first pass through the dust collection component 10 and then pass through the corresponding detection component 5. The dust collection component 10 is provided with a suction pipe 11 for downward air extraction. The top of the suction pipe 11 is connected to a dust collection piece 12. The dust collection piece 12 extends horizontally in the moving direction of the conveyor chain 2. The top of the dust collection piece 12 is provided with a plurality of equidistantly distributed The air holes are provided so that before the egg collides with the detection component 5, the egg will first pass over the dust suction component 10. During the downward suction process of the suction pipe 11, the dust suction component 12 disperses the downward airflow in the conveying direction, so that a dispersed downward suction force is generated at the bottom of the egg, thereby increasing the friction between the egg surface and the limiting roller 4 made of silicone material through the downward suction force, and cooperating with the rotation operation of the limiting roller 4 to improve the cleaning effect of the egg surface, and using the dust suction component 12 to suck out the cleared dust, thereby further reducing the impact on the collision sound detection.

[0033] In the present invention, the inner wall of the sealing plug 9 is provided with a plurality of mounting grooves, which are extended in the vertical direction. An inflatable strip 15 is fixed to the inner wall of the mounting groove. In the normal placement state, the bottom end of the probe 8 is located in the middle position of the sealing plug 9 and the inflatable strip 15, and the sealing plug 9 and the inflatable strip 15 at the overlapping position of the inner wall of the probe 8 are squeezed into the inside of the sealing plug 9, that is, the inflatable strip 15 at the position below the probe 8 will expand outwards a little. On the one hand, during the vertical descent of the probe 8, the inflatable strip 15 located below the probe 8 will gradually expand outwards to reduce the downward impact force of the probe 8, and the sealing plug 9 and the inflatable strip 15 that coincide with the inner wall of the bottom of the probe 8 will compress the sealing plug 9 and the inflatable strip 15. The inflatable strip 15 will apply outward force in the horizontal radial direction of the probe 8 to increase the friction between the sealing plug 9 and the probe 8, thereby reducing the upward rebound force of the probe 8, so as to ensure the effectiveness and accuracy of the collision detection; on the other hand, when the egg approaches the probe 8, if the top of the probe 8 is deflected to one side, the sealing plug 9 with an annular structure is used for position limiting and blocking, and when the probe 8 tilts to one side, the extrusion pressure of the top of the inflatable strip 15 corresponding to the tilted side will increase and the bottom of the inflatable strip 15 will bulge outward, so as to improve the position limiting stability of the bottom end of the tilted probe 8 through the bulging of the bottom, thereby ensuring the stability and accuracy of the collision detection.

[0034] Example 2: Reference Figures 1-8 , an egg crack detection device, based on embodiment 1, a plurality of fixing frames 22 are installed below the roller 3 in the mounting frame 1, the bottom end of the spring 7 and the bottom end of the sound collector 6 and the bottom of the suction pipe 11 are all connected to the fixing frame 22, and a chute 16 is provided at the position corresponding to the fixing frame 22 and the detection component 5. A slider 17 is fixed to the bottom end of the sound collector 6, and the slider 17 slides in the chute 16 along the direction of the conveyor chain 2. Buffer pads 18 are fixed on both sides of the chute 16, and the buffer pads 18 are distributed on the slider 17 when it slides. The two sides of the slider 17 are in contact with the buffer pads 18. When the egg moves to the position of the detection component 5 along with the limiting roller 4, the egg collides with the top of the probe 8, and the probe 8 can move a short distance in the moving direction with the egg for buffering. If the egg bounces up due to the collision and falls again, the position where it falls and the corresponding position of the probe 8 will be separated from the probe 8, thereby avoiding the second collision of the egg and affecting the accuracy of the detection. The buffer pads 18 on both sides are used to quickly restore the position of the probe 8 to a fixed position to ensure the accuracy and effectiveness of the detection of the next egg.

[0035] In the present invention, a plurality of mounting shells 19 are installed on the mounting frame 1 above the roller 3. The mounting shells 19 are arranged to be an arc-shaped structure with an upwardly arched top. A connecting belt 20 is fixed to the bottom of the mounting shell 19. The connecting belt 20 extends horizontally in the extension direction of the roller 3. An airbag 21 is installed between the mounting shell 19 and the connecting belt 20. After the airbag 21 is inflated, the connecting belt 20 is arched downward. It should be noted that: the mounting shell 19 is located at a side position corresponding to the detection component 5 facing the discharge direction. When the middle position of the placement groove where the egg is located corresponds to the probe 8, the mounting shell 19 is located between the probe 8 and the limiting roller 4 on the discharge direction side, so that the egg continues to move horizontally above the direction after colliding with the top of the probe 8, and is limited by the airbag 21, thereby preventing the egg from bouncing upward after the collision and falling again to cause a secondary collision, thereby further improving the accuracy of egg crack detection.

[0036] Example 3: Reference Figures 1-8 An egg crack detection device, based on Example 2, includes an air pressure monitoring module installed in the airbag 21. The air pressure monitoring module is used to monitor the air pressure intensity within the detection range of the airbag 21 in real time. If the air pressure intensity within the airbag 21 is too high, it indicates that the egg is squeezed upward for a long distance or the squeezing force is too strong, indicating that the vertical mobility of the egg at that location exceeds a predetermined distance, which may affect the accuracy of the collision sound detection. Therefore, it is necessary to cancel the crack detection audio at that location or retest the egg after listing.

[0037] Distance sensors are installed on both sides of the probe 8 on the fixing frame 22. The distance sensors are tilted and the top ends of the distance sensors are tilted toward the direction close to the probe 8. The two distance sensors are distributed on both sides of the probe 8 in the conveying direction. The two distance sensors respectively monitor the distance between the detection interval and the outer wall of the probe 8 in real time. The deflection angle of the probe 8 in the conveying direction is calculated based on the monitoring values of the two distance sensors. If the calculated deflection angle of the probe 8 is too large, it means that the probe 8 is squeezed too much by the egg under this position, which may affect the accuracy of the collision sound collection. Therefore, it is necessary to cancel the use of the sound collection data at this position or re-test the eggs after listing.

[0038] It should be noted that the detection zone is set within a fixed time period from when the egg collides with the probe 8 at a fixed position until the egg moves away from the probe 8 along with the limiting roller 4 .

[0039] In the present invention, the data acquired in real time by the air pressure monitoring module and the distance sensor module are uploaded to the central processing unit. After the data is processed, the air pressure value of the airbag 21 and the deflection angle of the probe 8 in the same detection interval are comprehensively analyzed to determine whether to use the data collected by the sound collector 6. The processing logic is as follows:

[0040] Step 1: The air pressure monitoring module obtains the air pressure value in the airbag 21 in real time , the two distance sensors obtain the distance value in real time and ;

[0041] Step 2: Calculate the deflection angle of probe 8 , , where and are the horizontal distances from the two distance sensors to the center of the probe 8, respectively. These two values are determined as fixed values during the installation and commissioning of the device;

[0042] Step 3: Compare the air pressure value with the normal range of the preset air pressure value. Compare the deflection angle with the pre-set normal range of deflection angle The normal range of air pressure value and the normal range of deflection angle can be determined in advance by placing eggs multiple times to conduct experiments to obtain normal sound data and realize the normal detection process.

[0043] like and , then it is considered that the state of the eggs in the detection range is normal, the data collected by the sound collector is reliable, and can be used to judge whether the eggs are cracked;

[0044] like or ,at the same time , indicating that the egg's vertical movement is abnormal, but the horizontal compression of the probe is normal. At this time, you can decide whether to further analyze or directly cancel the data based on the actual situation, such as the degree of abnormality;

[0045] like ,but or , indicating that the egg's horizontal squeezing of the probe is abnormal, while its vertical movement is normal. Similarly, the selection of data should be determined based on the degree of abnormality.

[0046] like or ,at the same time or , that is, the egg significantly interferes with the detection in both the vertical and horizontal directions, so the data collected by the sound collector at that location is directly canceled and the egg is marked for subsequent re-testing;

[0047] Through the above-mentioned multi-faceted design and technical means, the egg crack detection device has significant advantages in detection accuracy, efficiency and adaptability to different situations, and can better meet the crack detection needs on large-scale egg production lines.

[0048] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
