DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Embodiment 1: Refer to Figures 1 - 7, an egg crack detection device, including a mounting frame 1. On both sides of the mounting frame 1, there are conveyor chains 2. Between the two conveyor chains 2, there are multiple horizontally placed rollers 3. It should be noted that: the conveyor chain 2 can be selected to adopt conventional conveying methods such as chains or conveyor belts to ensure that after the roller 3 is connected to the conveyor chain 2, it can move with the conveyor chain 2 to convey eggs. And the horizontal extension direction of the roller 3 is perpendicular to the horizontal movement direction of the conveyor chain 2. A plurality of limiting rollers 4 are installed on the roller 3. The outer diameter of the limiting roller 4 gradually increases from the middle position towards both ends of the roller 3. Thus, the eggs can be exactly placed in the middle of the limiting rollers 4 between adjacent rollers 3, so that the eggs move with the conveyor chain 2 along with the limiting rollers 4 on both sides. The limiting roller 4 is made of silicone material. A detection component 5 is installed below the roller 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 arranged in the cavity. A sealing plug 9 is fixed on 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 middle cavity of the probe 8. The top end of the sound collector 6 extends above the sealing plug 9, and the top end 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. During the process of the eggs moving and being conveyed along with the conveyor chain 2, the roller 3 and the limiting roller 4, when the eggs move to the corresponding position of the detection component 5, the bottom of the eggs will touch the top end of the probe 8 to generate a knock. And the sound collector 6 inside the probe 8 processes the sound signals of the collision, including preprocessing operations such as amplification and filtering, then converts them into digital signals, and conducts spectral analysis to extract the spectral characteristics of the sound. The extracted sound spectral characteristics are compared with the known sound spectral data of cracked and non-cracked eggs, so as to judge whether the eggs have cracks. Generally speaking, due to the incomplete internal structure of cracked eggs, more high-frequency components will be generated during collision, and the attenuation speed of the sound may be faster. Judging through the collision sound can effectively avoid the problem of incomplete detection by shooting, and can conduct detection in real time during the egg transmission process, improving the detection efficiency and being suitable for rapid detection on large-scale production lines. Through the precise analysis of the sound spectrum, it can be more accurately judged whether the eggs have cracks. It should be noted that: according to experiments of placing eggs multiple times, the height position of the probe 8 is adjusted in advance so that the eggs can slightly collide with the probe 8 and will not cause damage to the eggs due to excessive extrusion force;In the design, the bottom end of the hollow cavity of the probe 8 is blocked by the sealing plug 9 on the outer wall of the sound collector 6. On the one hand, the lower part of the cavity is blocked to avoid the influence of external air vibration on the collection of collision sounds in the cavity, and the limiting roller 4 made of silica gel material is used to avoid the influence of the collision between the egg and other structures on the sound collection. On the other hand, the spring 7 enables the probe 8 to adapt to different states of the egg or eggs of different sizes within a certain range for collision. The frictional setting between the sealing plug 9 and the inner wall of the probe 8 can effectively reduce the impact force when the probe 8 presses down or rebounds upward, avoiding the secondary collision caused by the rapid upward rebound of the probe 8 after colliding with the egg, thereby improving the accuracy of audio data collection, and thus improving the accuracy and effectiveness of using the collision sound to judge the detection of egg cracks through the overall setting.

[0022] In the present invention, a plurality of detection components 5 are provided in the mounting frame 1, and the plurality of detection components 5 are arranged at equal intervals. A placement groove is provided between the corresponding limiting rollers 4 on two adjacent roller shafts 3 for placing eggs. When the detection component 5 is at the middle position of the placement groove, there is a placement groove between two adjacent detection components 5 distributed along the extension direction of the roller shaft 3, and there is a placement groove between two adjacent detection components 5 distributed along the direction of the conveying chain 2. Through the distribution setting of the above-mentioned plurality of detection components 5, multiple groups of eggs can be placed and conveyed for detection simultaneously along the extension direction of the roller shaft 3, and in the conveying direction, the same egg can be detected multiple times by the plurality of detection components 5. The accuracy of simple surface crack detection can be improved by comparing the multiple detection data multiple times; at the same time, in the present application, through the staggered setting of the plurality of detection components 5, the collision detection of eggs at adjacent positions is avoided in the conveying direction, thereby avoiding the mutual influence between sounds, and in the extension direction of the roller shaft 3, the adjacent positions are also avoided from colliding simultaneously, and the limiting roller 4 made of silica gel material at the middle position is used for stabilization, so as to avoid the influence of the mechanical vibration of the roller shaft 3 on the sound data collection; thus, through the staggered distribution setting of the above-mentioned plurality of detection components 5, the accuracy and effectiveness of collecting audio after the detection components 5 at each position collide with the eggs are effectively improved, the accuracy of detecting a single egg is improved through the detection operation of the plurality of detection components 5, and the working efficiency of detecting a large number of eggs is improved.

[0023] In the present invention, a rack 13 is fixedly installed below the roller shaft 3 on one side of the mounting bracket 1. The rack 13 extends horizontally in the moving direction of the conveyor chain 2 and is located at one end position in the extending direction of the roller shaft 3. A gear 14 is installed at a position on the outer wall of the roller shaft 3 corresponding to the rack 13. During the process of transporting eggs for detection, when the roller shaft 3 moves to the detection area, the gear 14 at the end of the roller shaft 3 will engage with the fixed rack 13. Thus, during the movement of the roller shaft 3 carrying the limiting roller 4 and the eggs, under the action of the engagement between the gear 14 and the rack 13, the roller shaft 3 will drive the limiting roller 4 to rotate simultaneously. The limiting roller 4 is made of silica gel material, so that the surface of the eggs can be cleaned by the rotation of the limiting roller 4, thereby improving the accuracy of subsequent collision detection. And under the action of friction, the eggs may flip between the two limiting rollers 4, so that different positions of the eggs can be subjected to collision detection when the same egg is detected by the detection components 5 at different positions, thereby further improving the detection accuracy.

[0024] In the present invention, a dust suction component 10 is provided on one side of the detection component 5 in the mounting bracket 1. The dust suction component 10 is located below the roller shaft 3, and the conveyor chain 2 moves from the dust suction component 10 towards the corresponding detection component 5. That is, during the movement of the eggs along with the conveyor chain 2, the eggs will first pass through the dust suction component 10 and then pass through the corresponding detection component 5. The dust suction component 10 is provided with a suction pipe 11 for exhausting air downward. The top end of the suction pipe 11 is communicated with a dust suction member 12. The dust suction member 12 extends horizontally in the moving direction of the conveyor chain 2, and a plurality of equally spaced air holes are formed in the top of the dust suction member 12. Thus, before the eggs are subjected to collision detection by the detection component 5, the eggs will first pass above the dust suction component 10. During the process of the suction pipe 11 exhausting air downward, the downward airflow is dispersed in the conveying direction through the dust suction member 12, so as to generate a dispersed downward suction force at the bottom of the eggs, thereby improving the friction force between the surface of the eggs and the limiting roller 4 made of silica gel material through the downward suction force, cooperating with the rotation operation of the limiting roller 4 to improve the cleaning effect on the surface of the eggs, and sucking out the dust cleared by the dust suction member 12, thereby further reducing the influence on the detection of the collision sound.

[0025] In the present invention, a plurality of mounting grooves are formed in the inner wall of the sealing plug 9. The mounting grooves extend 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 at the middle position between the sealing plug 9 and the inflatable strip 15, and the inner wall of the probe 8 presses the sealing plug 9 and the inflatable strip 15 at the overlapping position towards the inside of the sealing plug 9. That is, the inflatable strip 15 at the position below the probe 8 will bulge outwards slightly. On the one hand, during the vertical descent of the probe 8, the degree of outward bulging of the inflatable strip 15 located below the probe 8 will gradually increase, so as to slow down the downward impact force of the probe 8. The sealing plug 9 and the inflatable strip 15 that overlap with the inner wall of the bottom of the probe 8 will exert an outward force in the horizontal radial direction of the probe 8 to increase the friction force between the sealing plug 9 and the probe 8, thereby reducing the upward rebound force of the probe 8, so as to improve the effectiveness and accuracy of collision detection. On the other hand, when the egg approaches the probe 8 and causes the top of the probe 8 to deviate towards one side, the annular sealing plug 9 is used for limiting and blocking. When the probe 8 tilts towards one side, the extrusion force on the top of the inflatable strip 15 corresponding to the tilted side will increase and the bottom of the inflatable strip 15 will bulge outwards more, so as to improve the limiting stability of the bottom end of the tilted probe 8 through the bottom bulge, thereby ensuring the stability and accuracy of collision detection.

[0026] Embodiment 2: Refer to Figures 1 - 8 , an egg crack detection device. On the basis of Embodiment 1, a plurality of fixing frames 22 are installed below the roller shaft 3 in the mounting frame 1. The bottom ends of the springs 7, the bottom ends of the sound collectors 6, and the bottoms of the suction pipes 11 are all connected to the fixing frames 22. Sliding grooves 16 are formed at the positions of the fixing frames 22 corresponding to the detection assembly 5. A slider 17 is fixed to the bottom end of the sound collector 6. The slider 17 is limited to slide along the direction of the conveying chain 2 in the sliding groove 16. Buffer pads 18 are fixed to both sides of the sliding groove 16. The buffer pads 18 are distributed on both sides of the slider 17 in the sliding direction. 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 assembly 5 along with the limiting roller 4, the egg collides with the top end of the probe 8, and the probe 8 can move a short distance in the moving direction along with the egg for buffering. If the egg bounces up due to the collision and then falls again, the falling position and the corresponding position where the egg separates from the probe 8 are avoided, so as to prevent the egg from colliding again and affecting the detection accuracy. The buffer pads 18 on both sides are used to quickly restore the position of the probe 8 to the fixed position, so as to ensure the accuracy and effectiveness of the detection of the next egg.

[0027] In the present invention, a plurality of mounting shells 19 are mounted above the roller shaft 3 on the mounting frame 1. The mounting shell 19 is arranged in an arc structure with the top arched upward. A connecting belt 20 is fixed to the bottom of the mounting shell 19. The connecting belt 20 extends horizontally in the extending direction of the roller shaft 3. An airbag 21 is mounted between the mounting shell 19 and the connecting belt 20. After the airbag 21 is inflated, the connecting belt 20 arches downward. It should be noted that: the mounting shell 19 is located on the side of the corresponding detection component 5 towards the discharging 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 side of the discharging direction, so that the egg is limited by the airbag 21 above the horizontal moving direction after colliding with the top of the probe 8, thereby preventing the egg from bouncing upward and falling again to cause a secondary collision after the collision, and further improving the accuracy of egg crack detection.

[0028] Embodiment 3: Refer to Figures 1 - 8 , an egg crack detection device. On the basis of Embodiment 2, a pressure monitoring module is arranged in the airbag 21. The pressure monitoring module is used to monitor the air pressure intensity in the airbag 21 in the detection interval in real time. If the air pressure intensity in the airbag 21 is too high, it means that the upward extrusion distance of the egg is too large or the extrusion force is too large, indicating that the vertical activity of the egg at this position exceeds the predetermined distance, which may affect the accuracy of the collision sound detection. Therefore, it is necessary to cancel the use of the crack detection audio at this position or re-detect the egg after it is listed; Distance sensors are mounted on both sides of the probe 8 on the fixing frame 22. The distance sensors are inclined, and the top of the distance sensors is inclined towards 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 from the outer wall of the probe 8 in the detection interval in real time, and calculate the deflection angle of the probe 8 in the conveying direction through the monitored values of the two distance sensors; if the calculated deflection angle of the probe 8 is too large, it means that the extrusion degree of the egg below the probe 8 at this position is too much, 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-detect the egg after it is listed; It should be noted that: the detection interval is set within the 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.

[0029] In the present invention, the data obtained in real time by the pressure monitoring module and the distance sensor module are uploaded to the central processor. After data processing, it is judged whether to adopt the data collected by the sound collector 6 through comprehensive analysis of the air pressure value of the airbag 21 and the deflection angle of the probe 8 in the same detection interval. The processing logic is as follows: Step 1: The pressure monitoring module obtains the air pressure value in the airbag 21 in real time , and the two distance sensors respectively obtain the distance values in real time and ; Step 2: Calculate the deflection angle of the probe 8 , , where in the formula, and are respectively the horizontal distances from the two distance sensors to the center of the probe 8, and these two values are determined as fixed values during the installation and debugging of the device; Step 3: Compare the air pressure value with the normal range of the preset air pressure value , and compare the deflection angle with the normal range of the preset deflection angle . The normal ranges of the air pressure value and the deflection angle can be determined in advance through experiments of placing eggs multiple times to obtain the normal ranges of the air pressure value fluctuation and the deflection angle during the process of obtaining normal sound data for normal detection; If and , it is considered that the state of the egg in this detection interval is normal, and the data collected by the sound collector is reliable and can be used for egg crack judgment; If or , and at the same time , it indicates that the movement of the egg in the vertical direction is abnormal, but the extrusion situation of the probe in the horizontal direction is normal. At this time, according to the actual situation, such as the degree of abnormality, etc., it can be decided whether to further analyze or directly cancel this data; If , but or , it shows that the extrusion situation of the egg on the probe in the horizontal direction is abnormal, while the movement in the vertical direction is normal. Similarly, it is necessary to decide whether to retain or discard the data according to the degree of abnormality; If or , and at the same time or , that is, the egg causes great interference to the detection in both the vertical and horizontal directions, directly cancel the data collected by the sound collector at this position, and mark this egg for subsequent re - detection; Through the above - mentioned multi - aspect design and technical means, this egg crack detection device has significant advantages in terms of detection accuracy, efficiency, and adaptability to different situations, and can better meet the crack detection requirements of large - scale egg production lines.
