DETAILED DESCRIPTION

[0027] The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0028] See also Figure 1-Figure 5 The present invention provides an automatic detection and sorting device for loose yolk eggs, dark-spotted eggs and cracked eggs, comprising a frame 10, a clamping and conveying mechanism 20, a feeding mechanism 30, a detection mechanism 40 and a discharge mechanism 50. The clamping and conveying mechanism 20, the feeding mechanism 30, the detection mechanism 40 and the discharge mechanism 50 are all installed on the frame 10. The feeding mechanism 30 and the discharge mechanism 50 are respectively located on two opposite sides of the frame 10. The detection mechanism 40 is located between the feeding mechanism 30 and the discharge mechanism 50. The clamping and conveying mechanism 20 is used for clamping and conveying eggs to be detected. The clamping and conveying mechanism 20 moves to the discharge mechanism 50 after passing through the feeding mechanism 30 and the detection mechanism 40. During operation, the loading mechanism 30 pushes the eggs to be inspected onto the clamping and conveying mechanism 20. The clamping and conveying mechanism 20 carries the eggs and delivers them to the inspection mechanism 40. The inspection mechanism 40 is used to inspect the conveyed eggs for loose yolks, dark spots, cracks, etc. The inspected eggs are transported to the unloading mechanism 50 under the action of the clamping and conveying mechanism 20. The unloading mechanism 50 sorts the intact eggs and the defective eggs according to the inspection results.

[0029] In this embodiment, the feeding mechanism 30 includes a feeding belt 31 and a feeding push plate 32 provided on one side of the feeding belt 31. The feeding push plate 32 is movable relative to the feeding belt 31 along the width direction of the feeding belt 31. The eggs to be tested are placed on the feeding belt 31 in sequence along the length direction of the feeding belt 31. As the feeding belt 31 moves, the eggs gradually move forward. When the eggs move to align with the feeding push plate 32, the feeding push plate 32 is pushed out, thereby pushing the aligned eggs into the conveying mechanism 20. Furthermore, a groove (not shown) is formed on the upper surface of the feeding belt 31. The bottom of the egg is placed in the groove, which can limit the egg and prevent the egg from escaping from the feeding belt 31. In addition, the feeding push plate 32 is moved under the action of the feeding cylinder. Specifically, the cylinder end of the feeding cylinder is fixedly connected to the frame 10, and the output shaft of the feeding cylinder is fixedly connected to the feeding push plate.

[0030] The clamping and conveying mechanism 20 includes a carrier plate 21, a left clamping member 22, a right clamping member 23, an electromagnet 24 and an elastic member 25. The left clamping member 22 is fixedly connected to one side of the carrier plate 21, the right clamping member 23 is arranged opposite to the left clamping member 22 and is slidably arranged on the carrier plate 21, the right clamping member 23 can slide in a direction away from or close to the left clamping member 22, the electromagnet 24 is located on the side of the right clamping member 23 away from the left clamping member 22, the electromagnet 24 can magnetically absorb the right clamping member 23, and the elastic member 25 is telescopically arranged between the right clamping member 23 and the electromagnet 24 along the sliding direction of the right clamping member 23.

[0031] When in use, when the eggs have not been pushed into the clamping and conveying mechanism 20, the electromagnet 24 is energized, and the electromagnet 24 magnetically adsorbs the right clamping member 23, and at the same time, the elastic member 25 is compressed. When the clamping and conveying mechanism 20 moves to align with the feeding push plate 32 of the feeding mechanism 30, that is, the gap between the left clamping member 22 and the right clamping member 23 is aligned with the feeding push plate 32, at this time, the feeding push plate 32 moves to push the eggs on the feeding belt 31 into the gap between the left clamping member 22 and the right clamping member 23 on the carrier 21. Then, the electromagnet 24 loses power, and the electromagnet 24 releases the magnetic adsorption effect on the right clamping member 23, and the elastic member 25 is reset, and then pushes the right clamping member 23 to move toward the direction close to the left clamping member 22, and finally clamps and fixes the eggs between the left clamping member 22 and the right clamping member 23, so as to facilitate the transportation of eggs.

[0032] Furthermore, a positioning groove 214 is formed on the carrier plate 21 , and the positioning groove 214 can be used to preliminarily position the egg. During operation, the egg 214 is pushed into the positioning groove 214 .

[0033] The left clamping member 22 includes a left clamping ring 221 and a left connecting strip 222. The left clamping ring 221 is a circular ring structure. The left connecting strip 222 has a plurality of strips and is evenly fixedly connected to the left clamping ring 221 along the circumference of the left clamping ring 221. The right clamping member 23 includes a right clamping ring 231, a right connecting strip 232 and a magnetic member 233. The right clamping ring 231 is a circular ring structure. The right connecting strip 232 has a plurality of strips and is evenly fixedly connected to the right clamping ring 231 along the circumference of the right clamping ring 231. One end of the right connecting strip 232 away from the right clamping ring 231 is fixedly connected to the magnetic member 233. The magnetic member 233 is made of ferromagnetic material (for example, chromium, nickel, etc.) so that the electromagnet 24 can be magnetically attracted when it is energized. When working, the egg is clamped and fixed between the left clamping ring 221 and the right clamping ring 231. The left clamp ring 221 and the left connecting strip 222 together form a hollow cone shape, and the right clamp ring 231 and the right connecting strip 232 together form a hollow cone shape, so as to clamp and fix the egg. In this embodiment, the carrier plate 21, the left clamp ring 221, the left connecting strip 222, the right clamp ring 231 and the right connecting strip 232 are all made of transparent plastic. The left clamp ring 221 and the right clamp ring 231 made of transparent plastic can reduce the scratching of the egg shell, and at the same time can reduce the influence of the left clamp 22 and the right clamp 23 on the detection.

[0034] As a preferred embodiment, the carrier plate 21 is fixedly connected with a first fixing plate 211 and a second fixing plate 212, the first fixing plate 211 and the second fixing plate 212 are perpendicular to the carrier plate 21, the left connecting strip 222 is fixedly connected with the first fixing plate 211, the second fixing plate 212 is provided with a slide groove 2121, the magnetic member 233 can slide through the slide groove 2121, when the right clamping member 23 moves, the magnetic member 233 is slidably connected with the slide groove 2121, so as to guide the movement of the magnetic member 233. The outer wall of the magnetic member 233 and the groove wall of the slide groove 2121 are both polished to reduce the friction between the contact surfaces of the two, which is conducive to the smooth movement of the magnetic member 233.

[0035] Furthermore, a third fixing plate 213 is fixedly connected to the carrier plate 21 at a side of the second fixing plate 212 away from the first fixing plate 211, the electromagnet 24 is fixedly connected to the third fixing plate 213, and a supporting edge 2331 is convexly provided on the side wall of the magnetic attraction member 233 (see Figure 3 ), one end of the elastic member 25 elastically abuts against the abutting edge 2331, and the other end of the elastic member 25 elastically abuts against the third fixing plate 213. In this embodiment, the elastic member 25 is a spring sleeved outside the magnetic member 233. It can be understood that in other embodiments, the elastic member 25 can also be a rigid and elastic element such as a stainless steel shrapnel or a copper shrapnel, which is not limited here.

[0036] In this embodiment, the clamping and conveying mechanism 20 also includes a moving frame 26 and a driving member 27 for driving the moving frame 26 to move. The moving frame 26 is made of transparent plastic. A mounting groove 261 is provided on the moving frame 26. The carrier plate 21 is rotatably mounted in the mounting groove 261. The rotating carrier plate 21 can drive the eggs clamped and fixed between the left clamping member 22 and the right clamping member 23 to rotate, so that the eggs can be detected in multiple directions to improve the detection accuracy. In this embodiment, a driving motor 262 is installed on one side of the moving frame 26. The output shaft of the driving motor 262 is fixedly connected to the carrier plate 21 to drive the carrier plate 21 to rotate. The driving member 27 is a cylinder installed on the frame 10. The protruding end of the cylinder is fixedly connected to the moving frame 26. The clamping and conveying mechanism 20 is driven to move by the cylinder to realize the function of carrying eggs.

[0037] The detection mechanism 40 includes a dark box 41, a light source assembly 42 and a camera 43. The dark box 41 and the light source assembly 42 are both mounted on the frame 10. The camera 43 is mounted on the inner top wall of the dark box 41. The light source assembly 42 is located below the camera 43, so that the camera 43 and the light source assembly 42 are respectively located on the upper and lower sides of the clamping and conveying mechanism 20. The light source assembly 42 is used to emit a light source to illuminate the eggs from the bottom, and the light passes through the eggs. The camera 43 is used to take pictures. The pictures taken by the camera are transmitted to the terminal (for example, a computer, a mobile phone, etc.). After receiving the image information, the terminal uses an image processing algorithm to analyze it to detect whether the eggs have loose yolk, dark spots, cracks, etc.

[0038] The light source assembly 42 includes a rotating bracket 421 and a first light source 422 and a second light source 423 mounted on the rotating bracket 421 . The rotating bracket 421 is rotatable relative to the camera 43 so that any one of the first light source 422 and the second light source 423 can correspond to the camera 43 .

[0039] In this embodiment, the first light source 422 and the second light source 423 are both LED light sources, and the first light source 422 emits a light source with a wavelength of 570nm, and the second light source 423 emits a light source with a wavelength of 700nm. The basic principle of detection is:

[0040] For loose yolk egg detection, the yolk has a strong absorption effect on light around 570nm. Therefore, when an LED light source with a central wavelength of 570nm is used for irradiation, the color of the yolk area will be darker. Based on this characteristic, the image processing algorithm can be used to identify loose yolk eggs.

[0041] For dark-spotted eggs and cracked eggs, the yolk has a weaker absorption effect on light near 700nm, so the dark spots and cracks on the eggshell surface are most clear. Based on this characteristic, dark-spotted eggs and cracked eggs can be identified using image processing algorithms.

[0042] During the specific operation, the user only needs to rotate the corresponding light source to the bottom of the egg and illuminate the egg from the bottom of the egg.

[0043] In this embodiment, when the rotating bracket 421 rotates 180°, switching between the two light sources can be achieved. As a preferred embodiment, the light source assembly 42 also includes a fixed bracket 424, the fixed bracket 424 is an L-shaped structure, the fixed bracket 424 includes a horizontal plate 4241 and a vertical plate 4242 connected to each other, the horizontal plate 4241 is fixedly connected to the frame 10, the rotating bracket 421 is rotatably mounted on the vertical plate 4242, there is a certain gap between the rotating bracket 421 and the vertical plate 4242, the rotating bracket 421 is a "mouth" shaped structure, and a first switch 425 for controlling the first light source 422 and a second switch 426 for controlling the second light source 423 are installed on the rotating bracket 421. The first switch 425 and the second switch 426 are both spring-pressed switches. When the first switch 425 is pressed, the first light source 422 emits light, and when the second switch 426 is pressed, the second light source 423 emits light. When the pressing action on the switch is released, the switch will automatically pop up under the action of the spring, and the light source is extinguished. As a preferred embodiment, the ends of the first switch 425 and the second switch 426 are set to a hemispherical structure. In this way, when the rotating bracket 421 is rotated, the first switch 425 and the second switch 426 can be retracted into the rotating bracket 421 under the support of the edge of the longitudinal plate 4242, thereby playing the function of a press switch. During specific use, when one of the first switch 425 and the second switch 426 is pressed, the other is in an unpressed state. Therefore, among the two light sources, the switch corresponding to the light source rotated to the upper side is pressed, and the light source is in a lit state, while the other is in an extinguished state. In this way, by rotating the rotating bracket 421, the light source can be automatically lit and extinguished. The design is reasonable and ingenious.

[0044] In this embodiment, a rotating motor 427 is installed on the longitudinal plate 4242, and the output shaft of the rotating motor 427 is fixedly connected to the rotating bracket 421, so as to drive the rotating bracket 421 to rotate. The rotating motor 427 drives the rotating bracket 421 to rotate by 180 degrees each time.

[0045] In other embodiments, the light source assembly 42 can also be mounted on the mobile frame 26 and move with the mobile frame 26. In this case, the rotating bracket 421 can be rotatably mounted on the mobile frame 26. In this case, the light emitted by the light source can directly illuminate the bottom of the egg without passing through the mobile frame 26. Furthermore, the fixed bracket 424 can be fixedly mounted on the mobile frame 26, and the rotating bracket 426 is also mounted on the longitudinal plate 4242.

[0046] The unloading mechanism 50 includes a first unloading push plate 51 and a second unloading push plate 52, which are respectively arranged on opposite sides of the clamping and conveying mechanism 20. The first unloading push plate 51 and the second unloading push plate 52 are movable relative to the clamping and conveying mechanism 20. Specifically, the first unloading push plate 51 and the second unloading push plate 52 move along a moving direction perpendicular to the clamping and conveying mechanism 20. When the detection mechanism 40 detects that the egg is a qualified egg (i.e., without loose yolk, dark spots, cracks, etc.), the first unloading push plate 51 moves to push the egg from one side to the outside of the clamping and conveying mechanism 20; when the detection mechanism 40 detects that the egg is defective (i.e., there is at least one defect among loose yolk, dark spots and cracks), the second unloading push plate 52 moves to push the egg from the other side to the outside of the clamping and conveying mechanism 20, thereby realizing the automatic sorting function of the eggs.

[0047] As a preferred embodiment, the unloading mechanism 50 further includes a first unloading belt 53 and a second unloading belt 54 respectively located on opposite sides of the clamping conveying mechanism 20, the first unloading belt 53 and the second unloading belt 54 are both close to the carrier plate 21, the first unloading push plate 51 can push qualified eggs onto the first unloading belt 53 by moving, and the second unloading push plate 52 can push defective eggs onto the second unloading belt 54 by moving, and then they are transported to the corresponding egg tray under the conveying action of the unloading belt. The first unloading push plate 51 and the second unloading push plate 52 can be driven by a cylinder.

[0048] The automatic detection and sorting device for loose yolk eggs, dark-spotted eggs and cracked eggs of the present invention has the following working process: the eggs are arranged on the feeding belt 31 in sequence, and the eggs are moved forward under the action of the feeding belt 31. When the eggs move to the position aligned with the clamping and conveying mechanism 20, the feeding push plate 32 pushes the eggs onto the carrier plate 21. At this time, the electromagnet 24 loses power, and the right clamping member 23 clamps and fixes the eggs on the left clamping member 22 under the elastic force of the elastic member 25. Then, under the action of the driving member 27, the carrier plate 21 is moved to the bottom of the camera 43. According to the detection needs, the rotating bracket 421 is rotated to make the eggs The required light source illuminates the eggs upwards, then the camera 43 takes a picture of the eggs, and after receiving the image information, the terminal uses the image processing algorithm to analyze it to detect whether the eggs have scattered yolk, dark spots and cracks, etc. Then, the driving member 27 moves the carrier plate 21 to the position of the unloading mechanism 50, and the electromagnet 24 is energized to release the clamping and fixing effect on the eggs. One of the first unloading push plate 51 and the second unloading push plate 52 pushes the eggs onto the corresponding unloading belt according to the detection result, and then the driving member 27 moves the carrier plate 21 to the initial position, waiting for the next detection operation.
