Description

Technical Field

[0001] The present application relates to the field of egg inspection, and in particular to an egg visual inspection system. Background Art

[0002] After eggs are laid by poultry, they often need to be inspected to ensure that they have a good appearance and excellent quality when sold. In the existing related technologies, egg inspection is generally completed through an egg inspection system. These egg inspection systems usually include a conveyor belt, an irradiation lamp, and a visual camera. The conveyor belt is used to transport eggs, the irradiation lamp is used to illuminate the eggs on the conveyor belt, and the visual camera is used to obtain an image of the eggs on the conveyor belt, so as to know whether the eggs are good by comparing the images obtained by the visual camera with the images in the database.

[0003] Specifically, please refer to the utility model with announcement number CN 213756252 U, which discloses an automatic detection device for egg products, including a conveyor line, an illumination light source and a visual camera, wherein the illumination light source and the visual camera are both arranged above the conveyor line, the illumination light source is used to illuminate the egg products to be detected on the conveyor line, and the visual camera is used to capture images of the egg products to be detected on the conveyor line. The utility model realizes automatic detection through the visual camera, has high detection efficiency, and provides lighting through lights, so as to ensure that the images captured by the visual camera are clear and accurate, thereby ensuring the accuracy of detection by the visual detection device.

[0004] Regarding the above-mentioned related technologies, different customer groups often have different preferences for specific egg inspection features. For example, some customer groups may focus more on whether the egg appearance is neat, while others may have higher requirements for the cracks in the eggs. Therefore, using a single visual camera to inspect various egg inspection items has the technical problem of poor detection pertinence. Summary of the invention

[0005] In order to improve the pertinence of egg detection, the present application provides an egg visual detection system.

[0006] The egg visual inspection system provided in this application adopts the following technical solution:

[0007] An egg visual inspection system, comprising:

[0008] frame;

[0009] Crack detection components;

[0010] The crack detection component is arranged on the frame, and the crack detection component comprises a crack detection lamp and a crack detection camera, wherein the crack detection lamp is used to irradiate far-infrared light, and the crack detection camera is used to obtain images of eggs when the crack detection lamp irradiates the eggs, and the crack detection camera is a black and white camera;

[0011] External inspection components and / or internal inspection components;

[0012] The appearance detection component is arranged on the frame, and the appearance detection component includes an appearance detection lamp and an appearance detection camera, wherein the appearance detection lamp is used to irradiate incandescent light, and the appearance detection camera is used to obtain an image of the egg when the egg is irradiated by the appearance detection camera, and the type of the appearance detection camera is a color camera;

[0013] The internal detection component is arranged on the frame, and the internal detection component includes an internal detection lamp and an internal detection camera. The internal detection lamp is used to irradiate warm white light, and the internal detection camera is used to obtain images of eggs when being irradiated by the internal detection lamp. The type of the internal detection camera is a color camera.

[0014] By adopting the above technical solution, the far-infrared light irradiated by the crack detection lamp has a better penetration effect on the eggshell, and the far-infrared light penetrates the eggshell and attenuates more obviously after entering the egg, which makes the dot and line features on the side of the egg away from the crack detection lamp appear more clearly. In addition, the crack detection camera of the black and white camera type performs black and white development, accurately captures the black and white image dominated by dot and line features, so that the cracks that may exist in the eggshell are highlighted, thereby ensuring the accuracy of the crack detection image.

[0015] In addition, the crack detection camera, which is a black and white camera, can also highlight dirt that may exist on the smooth surface of eggs, so that the crack detection camera can assist in detecting whether there are defects such as dirt, dents, or sand shells on the appearance of eggs. Therefore, the crack detection camera can clearly detect whether there are cracks on the egg shell, and the crack detection camera can also take into account part of the egg appearance detection, making the egg visual inspection system have good applicability.

[0016] The warm white light from the internal inspection lamp also has a good penetration effect on the eggshell, but compared with far-infrared light, it will not show obvious attenuation after entering the egg, so that the internal features of the egg can be seen through the eggshell, and then the internal inspection camera can be used to detect whether there are loose yolks inside the egg or whether there are black spots and blood spots on the yolk surface. In addition, the color camera can better capture the black spots on the surface of the yolk (dark color), so that the possible defects inside the egg are highlighted, thereby ensuring the accuracy of the internal inspection image.

[0017] The incandescent light emitted by the appearance inspection lamp is not easy to change the color of the eggshell surface, so that the appearance inspection camera can capture the egg image with accurate color, and then accurately detect the dirt, eggshell color, eggshell dents, sand shell and other defects that may exist on the eggshell surface, ensuring the accuracy of the appearance inspection image.

[0018] Therefore, the crack detection component, appearance detection component and internal detection component can simultaneously meet the focus detection features of different customer groups, so that customer groups can focus on the required detection features. For example, for fresh eggs or pickled eggs (such as preserved eggs and salted eggs) whose surface is relatively smooth after production but whose internal quality is difficult to guarantee, the crack detection component and the internal detection component are used to focus on the detection of the cracks and internal conditions of the eggs, and the crack detection component is used to assist in the detection of the appearance of the eggs. For fresh eggs with poor surface quality but good internal quality after production, the crack detection component and the appearance detection component are used to focus on the detection of the cracks and appearance of the eggs.

[0019] Optionally, the rack is installed with an egg inspection box, the egg inspection box is provided with a first inspection chamber and a second inspection chamber, a light shielding is arranged between the first inspection chamber and the second inspection chamber, and the crack inspection lamp is located in the first inspection chamber;

[0020] The appearance detection light is located in the second detection chamber;

[0021] The internal detection light is located in the second detection chamber.

[0022] By adopting the above technical solution, the illumination in the first detection chamber and the illumination in the second detection chamber are not easy to interfere with each other, so that the egg surface is not easy to produce shadows, virtual images and mixed colors that affect the detection results, thereby ensuring the detection accuracy. For example, the crack detection lamp emitting far-infrared light is not easy to project mixed colors on the egg surface, and the internal detection lamp emitting warm white light is not easy to project shadows on the egg surface, thereby ensuring the accuracy of the detection image.

[0023] Optionally, the egg visual inspection system further comprises:

[0024] Egg conveying components;

[0025] The egg conveying assembly is used to convey eggs in a horizontal direction;

[0026] The egg inspection box is equipped with a light shielding plate, the first inspection chamber and the second inspection chamber are respectively located on both sides of the light shielding plate, and the light shielding plate is equipped with a middle shielding brush, which is located at the bottom of the light shielding plate.

[0027] By adopting the above technical solution, the light shielding plate blocks most of the light propagation in the first detection chamber and the second detection chamber, and promptly blocks the light propagation in the middle after the eggs pass through the bottom of the light shielding plate, thereby ensuring both the conveying efficiency and the detection accuracy.

[0028] Optionally, the crack detection lamp illuminates the eggs from the bottom, and the crack detection camera obtains images of the eggs illuminated by the crack detection lamp from the top;

[0029] The internal detection light illuminates the eggs from the bottom, and the internal detection camera obtains images of the eggs illuminated by the internal detection light from the top.

[0030] By adopting the above technical solution, the crack detection light and the crack detection camera (or the internal detection light and the internal detection camera) are respectively located on both sides of the egg, so that the camera can capture images with more obvious features, thereby ensuring detection accuracy.

[0031] Optionally, the egg visual inspection system further comprises:

[0032] Egg conveying components;

[0033] The egg conveying assembly is used to convey eggs in a horizontal direction, and the egg conveying assembly is provided with a plurality of egg conveying troughs, and the plurality of egg conveying troughs are used to place eggs;

[0034] The crack detection lamps and crack detection cameras are provided in plurality, wherein the plurality of crack detection lamps correspond to the egg conveying slots respectively, and the plurality of crack detection cameras correspond to the crack detection lamps respectively;

[0035] When there are no eggs in the egg conveying trough, the crack detection light corresponding to the egg conveying trough is turned off, and when there are eggs in the egg conveying trough, the crack detection light corresponding to the egg conveying trough is turned on;

[0036] The internal detection lights and internal detection cameras are provided in plurality, wherein the plurality of internal detection lights correspond to each egg conveying slot, and the plurality of internal detection cameras correspond to each internal detection light;

[0037] When there are no eggs in the egg conveying trough, the internal detection light corresponding to the egg conveying trough is turned off, and when there are eggs in the egg conveying trough, the internal detection light corresponding to the egg conveying trough is turned on.

[0038] By adopting the above technical solution, when there are no eggs in the egg conveying trough, that is, there is a gap, the crack detection light and the internal detection light are turned off, so that the crack detection camera and the internal detection camera located on the top of the detection light and facing the detection light are not prone to overexposure and distortion of the detection image, which is beneficial to improving the detection accuracy.

[0039] Optionally, the crack detection lamp includes a first lamp bead and a first perforated plate, the first lamp bead is provided with a plurality of first perforated plates, the first perforated plates are located on the top of each first lamp bead, the first perforated plates are penetrated with a plurality of first irradiation holes, and the plurality of first irradiation holes respectively correspond to each first lamp bead;

[0040] The internal detection lamp includes a second lamp bead and a second perforated plate, wherein the second lamp bead is provided with a plurality of second perforated plates, the second perforated plates are located on the top of each second lamp bead, and the second perforated plates are provided with a plurality of second irradiation holes, and the plurality of second irradiation holes respectively correspond to each second lamp bead.

[0041] By adopting the above technical solution, the first lamp bead irradiates light to the eggs through the first irradiation hole, and the second lamp bead irradiates light to the eggs through the second irradiation hole, so that the light irradiated by the first lamp bead is concentratedly emitted from the first irradiation hole, and the light irradiated by the second lamp bead is concentratedly emitted from the second irradiation hole, which is beneficial to ensure that the irradiation conditions of each egg remain highly consistent, reduce the situation where one adjacent lamp bead produces irrelevant and redundant irradiation to the eggs located on top of another adjacent lamp bead, thereby ensuring detection accuracy.

[0042] In addition, the situation where the light intensity received by another adjacent detection camera is too high, resulting in overexposure and distortion, is reduced when the adjacent egg conveying trough is vacant, thereby further ensuring the detection accuracy.

[0043] Optionally, the crack detection lamp further includes a first frosted plate, the first frosted plate is located between the first lamp bead and the first perforated plate, and the first frosted plate is light-transmissive;

[0044] The internal detection lamp further includes a second frosted plate, the second frosted plate is located between the first lamp bead and the second perforated plate, and the second frosted plate is light-transmissive.

[0045] By adopting the above technical scheme, the first frosted plate and the second frosted plate respectively make it difficult for the light of the first lamp bead and the second lamp bead to produce reflected reflections after irradiating the surface of the egg, and make it difficult for the egg to have uneven brightness when being irradiated, such as the middle of the egg is too bright and the outer edge is too dark, resulting in distorted image in the middle of the egg and dim and unclear image on the outer edge, which is beneficial to improve detection accuracy.

[0046] In addition, for batches of eggs with many cracks, the first frosted plate and the second frosted plate can reduce the occurrence of egg liquid dripping onto the first lamp bead or the second lamp bead, thereby reducing the difficulty of daily maintenance of the first lamp bead or the second lamp bead.

[0047] Optionally, the crack detection lamp further includes a first lamp holder, the first lamp bead and the first perforated plate are both mounted on the first lamp holder, and the first lamp holder is slidably matched with the frame;

[0048] The internal detection lamp also includes a second lamp holder, the second lamp bead and the second perforated plate are both installed on the second lamp holder, and the second lamp holder is slidably matched with the frame.

[0049] By adopting the above technical solution, when the crack detection lamp or the internal detection lamp needs to be maintained, the crack detection lamp or the internal detection lamp can be installed in place only by pushing and pulling, which is convenient and quick.

[0052] The egg conveying assembly comprises an egg conveying roller and a rotating driving member. The egg conveying roller is provided with a plurality of egg conveying rollers. An egg conveying trough is provided between two adjacent egg conveying rollers. The egg conveying trough is used for placing eggs. The rotating driving member is used for driving each egg conveying roller to rotate.

[0053] By adopting the above technical solution, the rotating driving member causes the two adjacent egg conveying rollers to rotate in the same direction, thereby causing the eggs located in the egg conveying trough to rotate under the friction of the two adjacent egg conveying rollers, so that all parts of the eggs are completely detected, thereby ensuring the detection accuracy.

[0054] Optionally, the egg conveying assembly further comprises a horizontal driving element, and the horizontal driving element is used to drive each egg conveying roller to move in a horizontal direction;

[0055] The rotating driving member includes a rotating gear and a rotating rack. The plurality of egg conveying rollers are rotatably mounted on the horizontal driving member. The rotating gear is provided with a plurality of rotating gears, which are respectively mounted on each egg conveying roller. The rotating rack is arranged in the horizontal direction.

[0056] By adopting the above technical solution, the horizontal driving element drives each egg conveying roller to move in the horizontal direction. When the rotating gear is engaged with the rotating rack, the rotating gear drives the egg conveying roller to rotate, thereby causing the eggs located in the egg conveying trough to rotate. The structure is simple and reliable.

[0057] In summary, the present application includes at least one of the following beneficial technical effects:

[0058] 1. The crack detection component, appearance detection component and internal detection component can simultaneously meet the focus detection features of different customer groups, so that customer groups can focus on the required detection features. For example, for fresh eggs or pickled eggs (such as preserved eggs and salted eggs) that have a relatively smooth surface after production but the internal quality is difficult to guarantee, the crack detection component and the internal detection component are used to focus on the detection of cracks and internal conditions of the eggs, and the crack detection component is used to assist in the detection of the appearance of the eggs. For fresh eggs that have poor surface appearance after production but good internal quality, the crack detection component and the appearance detection component are used to focus on the detection of cracks and appearance of the eggs;

DETAILED DESCRIPTION

[0075] The following is combined with Figure 1-12 This application is described in further detail.

[0076] In this application, the specification is attached Figure 1 , Instruction Manual Figure 2 , Instruction Manual Figure 4 And the instruction manual Figure 5 The arrow direction marked at the bottom refers to the conveying direction of eggs.

[0077] Embodiment 1:

[0078] Example 1 of the present application discloses an egg visual inspection system. Figure 1-4 The egg visual inspection system includes a frame 1, an egg conveying component, a crack detection component, an appearance detection component and an internal detection component.

[0079] Reference Figure 2 The egg conveying assembly includes an egg conveying roller 2 and a horizontal driving member 3. The egg conveying roller 2 is provided with a plurality of rollers, and two adjacent egg conveying rollers 2 are arranged side by side. Figure 3 The egg conveying roller 2 includes a conveying connecting rod 21 and a conveying sub-roller 22. Six conveying sub-rollers 22 are provided. The six conveying sub-rollers 22 are coaxially fixedly installed on the conveying connecting rod 21, and the six conveying sub-rollers 22 are evenly spaced. A depression is provided in the middle of the conveying sub-roller 22, and the depression makes the conveying sub-roller 22 as a whole arranged in an hourglass shape. An egg conveying trough 201 is formed between the middle depressions of two adjacent conveying sub-rollers 22, that is, a total of six egg conveying troughs 201 are provided between two adjacent conveying sub-rollers 22. The egg conveying trough 201 is used to place eggs, so that the eggs can be lifted up by the two conveying sub-rollers 22 together to limit the eggs and make the eggs move stably with the two conveying sub-rollers 22.

[0080] The horizontal driving member 3 is used to drive each egg conveying roller 2 to move in the horizontal direction, so that the eggs are lifted and conveyed in the horizontal direction by each conveying sub-roller 22. Specifically, in the embodiment of the present application, the horizontal driving member 3 includes a sprocket, a motor, and a chain driven by the sprocket and the motor (not shown in the figure), and the conveying connecting rod 21 is rotatably matched with the horizontal driving member 3, so that when the eggs enter the egg conveying trough 201 or are transported in the egg conveying trough 201, the external force on the eggs is released in time by the rotation of the conveying sub-roller 22, so that the eggs are not easily damaged again during the detection process.

[0081] Reference Figure 1 The frame 1 is fixedly mounted with an egg inspection box 11, which is arranged in a square shape and is located on the top of the egg conveying assembly. The egg inspection box 11 is provided with a plurality of inspection box doors, which are used to ensure that the interior of the egg inspection box 11 is normally in a light shielding state. In the present application, "light shielding state" means that it is difficult for external light to enter the interior of the egg inspection box 11, so that the internal illumination condition of the egg inspection box 11 is in an independent state compared with the external illumination condition, thereby reducing the adverse effect of external light on egg inspection.

[0082] Reference Figure 4 The egg inspection box 11 has a first inspection chamber 101 and a second inspection chamber 102 disposed therein. The first inspection chamber 101 and the second inspection chamber 102 are light-shielded from each other, that is, the illumination conditions between the first inspection chamber 101 and the second inspection chamber 102 are independent of each other. It is difficult for the light in the first inspection chamber 101 to enter the second inspection chamber 102, and it is also difficult for the light in the second inspection chamber 102 to enter the first inspection chamber 101.

[0083] Specifically, in the embodiment of the present application, the first detection chamber 101 and the second detection chamber 102 are light-shielded by an opaque light-shielding plate 12. The light-shielding plate 12 is located inside the egg detection box 11, and the light-shielding plate 12 is fixedly installed on the egg detection box 11, and the first detection chamber 101 and the second detection chamber 102 are respectively located on both sides of the light-shielding plate 12, and then the light-shielding plate 12 blocks the propagation of light between the first detection chamber 101 and the second detection chamber 102, so that the feature detection in the first detection chamber 101 and the feature detection in the second detection chamber 102 are not easy to interfere with each other, thereby ensuring the detection accuracy.

[0084] Reference Figure 4 The light shielding plate 12 is fixedly installed with a middle shielding brush 121, which is located at the bottom of the light shielding plate 12, and the bottom of the middle shielding brush 121 is arranged close to the conveying roller 22, so that the eggs can push open the middle shielding brush 121 under the limiting action of the conveying roller 22, and enter the first detection chamber 101 from the second detection chamber 102, and the middle shielding brush 121 can restore the deformation in time through its own elasticity after the eggs pass through the middle shielding brush 121 and hinder the light propagation between the first detection chamber 101 and the second detection chamber 102. In addition, the egg detection box 11 is also fixedly installed with two end shielding brushes 13, which are respectively located on both sides of the middle shielding brush 121, and the two end shielding brushes 13 are respectively located at the input end and the output end of the egg detection box 11, so that after the eggs enter or leave the egg detection box 11, the interior of the egg detection box 11 is closed in time.

[0085] Reference Figure 4 and Figure 5 The crack detection assembly includes a crack detection lamp 4 and a crack detection camera 5. The crack detection lamp 4 is located at the bottom of the egg conveying roller 2, and the crack detection lamp 4 is used to irradiate far-infrared light so that the far-infrared light can irradiate the eggs from the bottom. The far-infrared light can penetrate the eggshell near the crack detection lamp 4 well, and decays quickly after entering the egg, so that the eggshell away from the crack detection lamp 4 has only a weak light transmission effect, and then the crack characteristics and part of the appearance characteristics of the eggshell away from the crack detection lamp 4 are clearly visible, so that the crack detection camera 5 can capture the required detection image.

[0086] There are six crack detection cameras, and the six crack detection cameras 5 are all black and white cameras, and the six crack detection cameras 5 are all located in the first detection chamber 101, so that the crack detection cameras 5 are not easily disturbed by other light when capturing images. The six crack detection cameras 5 are all located on the top of the egg conveying roller 2, and the six crack detection cameras 5 correspond to each egg conveying groove 201 formed between the two egg conveying rollers 2, so that the six crack detection cameras 5 can respectively obtain the image of each egg when it is illuminated by the crack detection lamp 4 from the top, so as to respectively detect the cracks and appearance of each egg, so as to ensure the pertinence and accuracy of the detection.

[0087] Six crack detection cameras 5 are installed on the egg inspection box 11 through crack detection mounting rods 51. Specifically, the crack detection mounting rods 51 are installed on the key slots extending in the vertical direction provided in the egg inspection chamber through bolts (not shown in the figure) and nuts (not shown in the figure), and the six crack detection cameras 5 are distributed along the length direction of the crack detection mounting rods 51, and the six crack detection cameras 5 are all installed on the crack detection mounting rods 51 through bolts, so that the height of the crack detection cameras 5 can be adjusted in the vertical direction through the bolts and the key slots, so that the images of the crack detection cameras 5 can be adjusted during the operation of the machine, so as to reduce the adverse effects of changes in camera specifications or light intensity on the images.

[0088] Reference Figure 6 and Figure 7 The crack detection lamp 4 includes a first lamp holder 41, a first heat sink 42, a first lamp bead 43, a first frosted plate 44 and a first perforated plate 45. The first lamp holder 41 is in a rectangular parallelepiped configuration, and the bottom of the first lamp holder 41 is slidably matched with the frame 1 through two profiles with an "L"-shaped cross section, so that the crack detection lamp 4 can be disassembled and assembled by pushing and pulling, thereby reducing the difficulty of maintenance. A cavity is provided in the first lamp holder 41, and the first heat sink 42 is installed in the cavity of the first lamp holder 41 by bolts, and the cross section of the first heat sink 42 is in an "E"-shaped configuration, so as to ensure the contact area between the first heat sink 42 and the outside world, thereby ensuring the heat dissipation effect of the first heat sink 42.

[0089] There are a plurality of first lamp beads 43, all of which are far-infrared lamp beads, and the first lamp beads 43 are fixedly mounted on the top of the first heat sink 42 to reduce the operating temperature of each first lamp bead 43. The first lamp beads 43 are arranged in a plurality of rows, and specifically in the embodiment of the present application, the first lamp beads 43 are distributed in a specification of three rows and six columns, so that the six first lamp beads 43 in each row respectively illuminate the eggs in each egg conveying trough 201, thereby ensuring the pertinence and accuracy of the detection.

[0090] The first frosted plate 44 is installed on the top of the first lamp holder 41 by bolts (not shown in the figure), and the first frosted plate 44 is covered on each first lamp bead 43, and the first frosted plate 44 is light-transmissive, so that the light irradiated by the first lamp bead 43 is diffused and softened after passing through the first frosted plate 44, so that the light of the first lamp bead 43 is evenly irradiated on the bottom of the egg, so that all parts of the egg are evenly illuminated and the crack detection camera 5 captures accurate crack features and appearance features to ensure detection accuracy. In addition, the first frosted plate 44 also makes it difficult for dirt such as egg liquid to drip onto the surface of the first lamp bead 43 and the first heat sink 42, thereby reducing the difficulty of maintenance and cleaning.

[0091] The first perforated plate 45 is installed on the top of the first lamp holder 41 by bolts (not shown in the figure), and the first perforated plate 45 is located on the top of the first frosted plate 44. The first perforated plate 45 is penetrated with a plurality of first irradiation holes 401, and the plurality of first irradiation holes 401 correspond to the first lamp beads 43, so that the light of the first lamp beads 43 passes through the shielding of the first perforated plate 45, and then irradiates the bottom of the eggs after passing through the first irradiation holes 401, thereby reducing the repeated secondary irradiation of one first lamp bead 43 to the eggs corresponding to another adjacent first lamp bead 43, and the occurrence of inconsistent lighting conditions of the eggs, thereby reducing the difficulty of adjusting the machine and ensuring the detection accuracy.

[0092] Reference Figure 4 and Figure 5 The internal detection assembly includes an internal detection lamp 6 and an internal detection camera 7. The internal detection lamp 6 is located at the bottom of the egg conveying roller 2, and the internal detection lamp 6 is used to irradiate warm white light, so that the warm white light can irradiate the eggs from the bottom. The warm white light can penetrate the eggshell well, so that the internal features of the egg can be clearly seen through the eggshell, so that the internal detection camera 7 can capture the required detection image and detect whether there are loose yolks inside the egg or whether there are black spots and blood spots on the yolk surface.

[0093] There are six internal detection cameras 7, and the type of the six internal detection cameras 7 is color camera, so as to identify the black spots and blood spots on the surface of the egg yolk that are close to the light and dark of the egg yolk. The six internal detection cameras 7 are all located in the second detection chamber 102, so that the internal detection cameras 7 are not easily disturbed by external light and the light in the first detection chamber 101 when capturing images. The six internal detection cameras 7 are all located at the top of the egg conveying roller 2, and the six internal detection cameras 7 correspond to each egg conveying groove 201 formed between the two egg conveying rollers 2, so that the six internal detection cameras 7 can respectively obtain the image of each egg when it is illuminated by the internal detection lamp 6 from the top, so as to detect the inside of each egg respectively, so as to ensure the pertinence and accuracy of the detection.

[0094] Six internal detection cameras 7 are installed on the egg detection box 11 through the internal detection mounting rod 71. Specifically, the internal detection mounting rod 71 is installed on the keyway extending in the vertical direction provided in the egg detection chamber through bolts (not shown in the figure) and nuts (not shown in the figure), and the six internal detection cameras 7 are distributed along the length direction of the internal detection mounting rod 71, and the six internal detection cameras 7 are all installed on the internal detection mounting rod 71 through bolts, so that the height of the internal detection camera 7 can be adjusted in the vertical direction through the bolts and the keyway, so as to adjust the image of the internal detection camera 7 during the operation of the machine, so as to reduce the adverse effects of changes in camera specifications or light intensity on the image.

[0095] Reference Figure 5 , Figure 6 as well as Figure 7 The internal detection lamp 6 is located on one side of the crack detection lamp, and the internal detection lamp 6 is close to the input end of the egg detection box 11. The structure of the internal detection lamp 6 is basically consistent with the technical features of the crack detection lamp, and the only difference is that the type of the second lamp bead is a warm white light lamp bead;

[0096] Specifically, the internal detection lamp 6 includes a second lamp holder, a second heat sink, a second lamp bead (not shown in the figure), a second frosted plate and a second perforated plate. The second lamp holder is in a rectangular parallelepiped configuration, and the bottom of the second lamp holder is slidably matched with the frame 1 through two profiles with "L"-shaped cross-sections, so that the internal detection lamp 6 can be disassembled and assembled by pushing and pulling, thereby reducing the difficulty of maintenance. A cavity is provided in the second lamp holder, and the second heat sink is installed in the cavity of the second lamp holder by bolts, and the cross-section of the second heat sink is in an "E"-shaped configuration, so as to ensure the contact area between the second heat sink and the outside world, thereby ensuring the heat dissipation effect of the second heat sink.

[0097] There are a plurality of second lamp beads, all of which are far-infrared lamp beads, and the second lamp beads are fixedly mounted on the top of the second heat sink to reduce the operating temperature of each second lamp bead. The second lamp beads are arranged in a plurality of rows, and specifically in the embodiment of the present application, the second lamp beads are distributed in a specification of three rows and six columns, so that the six second lamp beads in each row correspond to irradiate the eggs in each egg conveying trough 201, thereby ensuring the pertinence and accuracy of the detection.

[0098] The second frosted plate is installed on the top of the second lamp holder by bolts (not shown in the figure), and the second frosted plate covers each second lamp bead, and the second frosted plate is light-transmissive, so that the light irradiated by the second lamp bead is diffused and softened after passing through the second frosted plate, so that the light of the second lamp bead is evenly irradiated on the bottom of the egg, reducing the generation of reflections, so that all parts of the egg are evenly illuminated and the crack detection camera 5 captures accurate crack features and appearance features to ensure detection accuracy. In addition, the second frosted plate also makes it difficult for dirt such as egg liquid to drip onto the surface of the second lamp bead and the second heat sink, thereby reducing the difficulty of maintenance and cleaning.

[0099] The second perforated plate is installed on the top of the second lamp holder by bolts (not shown in the figure), and the second perforated plate is located on the top of the second frosted plate. The second perforated plate is penetrated with a plurality of second irradiation holes, and the plurality of second irradiation holes correspond to each second lamp bead, so that the light of the second lamp bead passes through the shielding of the second perforated plate, and then irradiates the bottom of the egg after passing through the second irradiation holes, thereby reducing the repeated secondary irradiation of one second lamp bead to the egg corresponding to another adjacent second lamp bead, and the occurrence of inconsistent lighting conditions of each egg, thereby reducing the difficulty of adjusting the machine and ensuring the detection accuracy.

[0100] Reference Figure 8 The egg detection box 11 is equipped with six egg sensors 111, which are all fixedly installed at the input end of the egg detection box 11, and the six egg sensors 111 are all located at the top of the end shielding brush 13, and the six egg sensors 111 correspond to each egg conveying groove 201 formed between two egg conveying rollers 2. The egg sensor 111 is used to detect whether the egg conveying groove 201 has "eggs" or "no eggs", and the egg sensor 111 is electrically connected to the crack detection lamp 4 and the internal detection lamp 6 through a processing system (not shown in the figure).

[0101] When the egg sensor 111 detects that the egg conveying trough 201 has “eggs present”, the processing system stores the position of the egg conveying trough 201. When the egg conveying trough 201 moves to the top of the crack detection light 4 or the top of the internal detection light 6, the processing system controls the crack detection light 4 or the internal detection light 6 to turn on, respectively, so as to detect the eggs in the egg conveying trough 201.

[0102] When the egg sensor 111 detects "no eggs" for the egg conveying slot 201, the processing system stores the position of the egg conveying slot 201. When the egg conveying slot 201 moves to the top of the crack detection lamp 4 or the top of the internal detection lamp 6, the processing system controls the crack detection lamp 4 to be turned off or the internal detection lamp 6 to be turned off, so that the crack detection camera 5 and the internal detection camera 7 are not easily overexposed due to excessive brightness, thereby reducing the occurrence of distortion of the detection image to ensure the detection accuracy. In addition, the technical effect of turning off the crack detection lamp 4 or the internal detection lamp 6 when the egg placement slot is vacant can also be achieved through mechanical structures such as connecting rods or ropes, which will not be repeated in the embodiments of the present application.

[0103] Reference Figure 4 and Figure 5 , the external detection component is located in the second detection chamber 102, and the external detection component includes an appearance detection lamp 8 and an appearance detection camera 9. There are two appearance detection lamps 8, both of which are located at the bottom of the internal detection camera 7, and the two appearance detection lamps 8 are distributed along the conveying direction of the eggs to reduce the occurrence of the shadow of the internal detection camera 7 projected on the surface of the eggs, thereby ensuring the accuracy of the detection image. The appearance detection lamp 8 is used to irradiate incandescent light, and the appearance detection lamp 8 is arranged in a strip shape to ensure that the surface of the egg is fully irradiated by the incandescent light, and the surface of the egg is not easy to show a color inconsistent with the naked eye due to the irradiation of the appearance detection lamp 8, thereby accurately showing the defects such as dirt, depression or sand shell on the surface of the egg, and accurately showing the color when the customer observes with the naked eye.

[0104] There are two appearance inspection cameras 9, and both of them are color cameras, and both of them are located on top of the internal inspection camera 7, so that the inspection range of the appearance inspection camera 9 can be ensured by a smaller number of appearance inspection cameras 9, thereby detecting appearance defects on the surface of eggs at a lower cost.

[0105] Two appearance inspection cameras 9 are installed on the egg inspection box 11 through the appearance inspection mounting rod 91. Specifically, the appearance inspection mounting rod 91 is installed on the keyway extending in the vertical direction provided in the egg inspection chamber through bolts (not shown in the figure) and nuts (not shown in the figure), and the two appearance inspection cameras 9 are distributed along the length direction of the appearance inspection mounting rod 91, and the two appearance inspection cameras 9 are installed on the appearance inspection mounting rod 91 through bolts, so that the height of the appearance inspection camera 9 can be adjusted in the vertical direction through the bolts and the keyway, so as to adjust the image of the appearance inspection camera 9 during the operation of the machine, so as to reduce the adverse effects of changes in camera specifications or light intensity on the image.

[0106] The crack detection camera 5, the internal detection camera 7 and the appearance detection camera 9 are all electrically connected to a processing system (not shown in the figure). When the crack detection camera 5, the internal detection camera 7 or the appearance detection camera 9 detects eggs that do not meet the requirements, the processing system stores and memorizes the position sequence of the egg conveying trough 201 where the eggs are located and discards them after detection.

[0107] The implementation principle of the egg visual inspection system in Example 1 of the present application is: through a crack detection component that irradiates far-infrared light and captures black and white images, an internal detection component that irradiates warm white light and captures color images, and an appearance detection component that irradiates incandescent light and captures color images, cracks, internal parts and appearance are accurately detected simultaneously, thereby meeting the emphasis on detection features of different customer groups, so that customer groups can focus on detecting the required detection features in a targeted manner.

[0108] Embodiment 2:

[0109] Embodiment 2 of the present application discloses an egg inspection method, which is applied to the egg visual inspection system described in Embodiment 1, and comprises the following steps:

[0110] S1. Several eggs are transported and placed in the egg transport trough 201, and the eggs are moved horizontally toward the egg inspection box 11 along the egg transport roller 2.

[0111] S2. The eggs move to the bottom of the egg sensor 111. The egg sensor 111 detects whether the egg conveying trough 201 has eggs or no eggs. The processing system (not shown) memorizes the egg conditions and sequence positions of each egg conveying trough 201.

[0112] S3, after each row of eggs enters the egg inspection box 11 in turn, the appearance inspection light 8 is turned on, and the appearance inspection camera 9 sequentially inspects the appearance characteristics of each row of eggs entering the egg inspection box 11. For eggs that do not meet the requirements, the processing system memorizes the position sequence of the eggs, and determines whether they need to be discarded according to customer requirements in the future.

[0113] S4, after each row of eggs moves to the top of the second lamp bead of each internal detection lamp 6, the eggs are temporarily stopped from being transported and the appearance detection lamp 8 is turned off. Subsequently, according to the egg situation of the egg conveying trough 201 detected by the egg sensor 111, the processing system determines the second lamp bead that needs to be turned on or off.

[0114] For the egg conveying trough 201 with eggs placed therein, the second lamp bead of the internal detection lamp 6 corresponding to the egg conveying trough 201 is turned on, and the internal detection camera 7 corresponding to the egg conveying trough 201 captures the image of the eggs illuminated by the warm white light of the internal detection lamp 6, thereby simultaneously detecting the internal features of each row of eggs. For eggs that do not meet the requirements, the processing system memorizes the position sequence of the eggs, and determines whether they need to be discarded according to customer requirements in the future.

[0115] S5. The eggs continue to be transported in the horizontal direction and pass through the middle shielding brush 121 to enter the other side of the egg inspection chamber, that is, the first inspection chamber 101.

[0116] After each row of eggs moves to the top of the first lamp bead 43 of each crack detection lamp 4, the eggs are temporarily stopped from being transported. Then, according to the egg situation of the egg conveying trough 201 detected by the egg sensor 111, the processing system determines the crack detection lamp 4 that needs to be turned on or off.

[0117] For the egg conveying trough 201 with eggs placed therein, the first lamp bead 43 of the crack detection lamp 4 corresponding to the egg conveying trough 201 is turned on, and the crack detection camera 5 corresponding to the egg conveying trough 201 captures the image of the eggs irradiated by the far-infrared light of the crack detection lamp 4, thereby detecting the crack characteristics of each egg. For eggs that do not meet the requirements, the processing system memorizes the position sequence of the eggs, and determines whether they need to be discarded according to customer requirements in the future.

[0118] S6, the eggs that have been tested leave the output end of the egg testing box 11 and move to the subsequent processing mechanism to comprehensively determine the execution of the following instructions based on the indicators required by the customer: ignore, classify, re-test and / or discard.

[0119] Embodiment 3:

[0120] Reference Fig. 9 Embodiment 3 of the present application discloses an egg visual inspection system, which differs from Embodiment 1 only in that the egg visual inspection system is not provided with an internal inspection component, that is, is not provided with an internal inspection light 6 and an internal inspection camera 7.

[0121] The implementation principle of the egg visual inspection system in Example 3 of the present application is as follows: for eggs with higher internal quality after production, the internal characteristics of the eggs are not inspected by the internal inspection component, but only the external characteristics of the eggs are inspected by the appearance inspection component and the crack characteristics of the eggs are inspected by the crack detection component, thereby reducing the equipment cost of egg inspection and improving the inspection speed.

[0122] Embodiment 4:

[0123] Reference Fig.10Embodiment 4 of the present application discloses an egg visual inspection system, which differs from Embodiment 1 only in that the egg visual inspection system is not provided with an external inspection component, that is, it is not provided with an appearance inspection light 8 and an appearance inspection camera 9.

[0124] The implementation principle of the egg visual inspection system in Example 4 of the present application is as follows: for eggs with high appearance quality after production, the external features of the eggs are not inspected by external inspection components, but only the internal features of the eggs are inspected by internal inspection components, and the crack features and partial appearance features of the eggs are inspected by crack detection components, thereby reducing the equipment cost of egg inspection and improving the inspection speed.

[0125] Embodiment 5:

[0126] Example 5 of the present application discloses an egg visual inspection system, which differs from Example 1 only in that the technical features of the egg conveying components are inconsistent.

[0127] Reference Fig.11 and Fig.12 The egg conveying assembly also includes a rotating drive member, which is used to drive each egg conveying roller 2 to rotate, so that when the eggs are placed in the egg conveying trough 201, they rotate under the friction of two adjacent conveying sub-rollers 22, thereby allowing the crack detection component, the internal detection component and the appearance detection component to detect the eggs from multiple angles, thereby ensuring the detection accuracy.

[0128] Specifically, in the embodiment of the present application, the rotating driving member includes a rotating gear 211 and a rotating rack 14. A plurality of rotating gears 211 are provided, and the plurality of rotating gears 211 are coaxially fixedly installed on each conveying connecting rod 21, so as to drive each conveying sub-roller 22 to rotate through the rotating gear 211. The rotating rack 14 is fixedly installed on the frame 1, and the rotating rack 14 is arranged in the horizontal direction. In the process that the horizontal driving member 3, i.e., the chain drives the egg conveying roller 2 to move in the horizontal direction, the rotating gear 211 contacts and meshes with the rotating rack 14, thereby driving the conveying connecting rod 21 and the conveying sub-roller 22 to rotate through the rotating gear 211 and the rotating rack 14, and causing the eggs to rotate in the egg conveying trough 201.

[0129] The implementation principle of the egg visual inspection system in Example 5 of the present application is: by rotating the gear 211 and the rotating rack 14, the eggs are rotated during the egg inspection process, so that the crack detection component, the internal detection component and the appearance detection component can inspect the eggs from multiple angles, thereby ensuring the inspection accuracy.

[0130] Embodiment 6:

[0131] Example 6 of the present application discloses an egg inspection method, which is applied to the egg visual inspection system described in Example 5, and the difference from the egg inspection method described in Example 2 is that the technical features of S4 and S5 are inconsistent:

[0132] S4, each row of eggs moves forward to the top of each row of second lamp beads of the internal detection lamp 6 in sequence, and after the eggs move forward one row, the conveying is temporarily stopped and the appearance detection lamp 8 is turned off. Subsequently, according to the egg situation of the egg conveying trough 201 detected by the egg sensor 111, the processing system determines the second lamp beads that need to be turned on or off.

[0133] For the egg conveying trough 201 where eggs are placed, the second lamp bead of the internal detection lamp 6 corresponding to the egg conveying trough 201 is turned on, and the internal detection camera 7 corresponding to the egg conveying trough 201 captures the image of the eggs illuminated by the warm white light of the internal detection lamp 6, thereby performing one round of detection on the internal features of a row of eggs.

[0134] After one round of detection is completed, the eggs rotate and continue to move forward one row to the top of another row of second lamp beads, so as to perform another round of detection on the internal features of a row of eggs, until each row of second lamp beads has irradiated a row of eggs, and the internal detection camera 7 captures the required images in each round of detection, so as to complete all rounds of internal detection of a row of eggs. For eggs that do not meet the requirements, the processing system memorizes the position sequence of the eggs and determines whether they need to be discarded according to customer requirements in the future.

[0135] S5. The eggs continue to be transported in the horizontal direction and pass through the middle shielding brush 121 to enter the other side of the egg inspection chamber, that is, the first inspection chamber 101.

[0136] Each row of eggs moves forward in sequence to the top of each row of first lamp beads 43 of the crack detection lamp 4, and the conveying of the eggs is temporarily stopped after the eggs move forward one row. Subsequently, according to the egg situation of the egg conveying trough 201 detected by the egg sensor 111, the processing system determines the first lamp beads 43 that need to be turned on or off.

[0137] For the egg conveying trough 201 where eggs are placed, the first lamp bead 43 of the crack detection lamp 4 corresponding to the egg conveying trough 201 is turned on, and the crack detection camera 5 corresponding to the egg conveying trough 201 captures the image of the eggs illuminated by the far-infrared light of the crack detection lamp 4, thereby performing one round of detection on the crack characteristics of a row of eggs.

[0138] After one round of detection is completed, the eggs rotate and continue to move forward one row to the top of another row of first lamp beads 43, so as to perform another round of detection on the crack characteristics of a row of eggs, until each row of first lamp beads 43 has irradiated a row of eggs, and the crack detection camera 5 captures the required images in each round of detection, so as to complete all rounds of crack detection of a row of eggs. For eggs that do not meet the requirements, the processing system memorizes the position sequence of the eggs, and determines whether they need to be discarded according to customer requirements in the future.

[0139] Embodiment 7:

[0140] Example 7 of the present application discloses a processing system for an egg visual inspection system, which is applied to the egg visual inspection system of Example 1, 3, 4 or 5, or the egg inspection method of Example 2 or 6.

[0141] S1. Input the good product end value image and the defective product end value image corresponding to the required detection feature into the processing system. The processing system will classify the detection feature results into several levels in order according to the good product end value image and the defective product end value image. The several levels of the detection features are further divided into two categories of qualified and unqualified according to customer needs.

[0142] S2. The processing system compares the image captured by the detection camera with the good product end value image and the bad product end value image, and then obtains the level of the egg product detection feature, thereby determining whether the egg product detection feature is qualified or unqualified.

[0143] For example, it is now necessary to detect the color characteristics of eggs, and stipulate that white eggs are good products at the end value, and pink eggs are bad products at the end value.

[0144] S1. Input the good product end value image of white eggs and the defective product end value image of pink eggs to the processing system. The processing system divides the color feature results into ten levels in order according to the good product end value image and the defective product end value image and the RGB value as the standard, and the first to sixth levels are qualified, and the seventh to tenth levels are unqualified.

[0145] S2. The processing system compares the image captured by the detection camera with the image of the good end value of the white egg and the image of the bad end value of the pink egg, and then concludes that the grade of the egg color feature is the fifth grade, thereby determining that the egg color feature is qualified.

[0146] The implementation principle of the processing system of the egg visual inspection system in Example 7 of the present application is as follows: the determination of egg inspection characteristics only requires comparison of good product end value images and bad product end value images, without the need to call a huge database for item-by-item comparison, and the recognition and inspection speed is fast.

[0147] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
