Description

Technical Field

[0001] This invention relates to the field of egg identification technology, and more specifically to an automatic egg identification device. Background Technology

[0002] In the fields of food processing and automated testing technology, particularly in the sorting and quality control of eggs, there is a demand for highly efficient and accurate testing systems. Eggs are an important part of the daily diet of consumers worldwide, and their appearance and internal quality directly affect food safety and consumer health. Traditional egg sorting relies on manual operation, which faces problems of low efficiency and insufficient accuracy, especially when distinguishing eggs with similar colors, such as pink-shelled eggs and brown-shelled eggs, as well as detecting defective products such as broken or cracked eggs.

[0003] With technological advancements, automated sorting systems have begun to be introduced into the egg sorting process. However, existing systems often can only handle limited tasks, such as simple color sorting or size measurement, and cannot comprehensively assess the quality of eggs. Furthermore, inspecting the internal quality of eggs typically requires additional steps and equipment, which not only increases costs but also reduces the efficiency of the inspection process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide an automatic egg identification device that integrates multispectral imaging and ultrasonic detection. This device boasts advantages such as high efficiency and accuracy, reduces labor costs, and meets the needs of modern large-scale production lines.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: an automatic egg identification device, including a frame, a conveyor belt on the frame and identification stations arranged along the conveying direction of the conveyor belt;

[0006] The identification station includes a first identification component, a second identification component, a feeding component, and a discharging component arranged sequentially.

[0007] The first identification component includes an adsorption gun for adsorbing eggs to be identified and an ultrasonic generator for ultrasonic testing of the eggs to be identified. The ultrasonic generator performs ultrasonic testing on the eggs adsorbed by the adsorption gun and sends the results to an integrated controller. The adsorption gun transfers the eggs that have completed ultrasonic testing to the second identification component.

[0008] The second identification component includes a detection tank with an inlet and an outlet. The outlet has two sets of rollers with a gap between them. The suction gun releases the eggs that have undergone ultrasonic testing at the inlet. The released eggs roll past the outlet and fall between the two sets of rollers. The second identification component also includes a camera that performs visual inspection on the eggs falling between the two sets of rollers. The camera sends the captured visual image to the integrated controller. The gap between the two sets of rollers is adjustable.

[0009] The feeding assembly includes a separating plate located below the two sets of rollers. The separating plate includes a defective product feeding end and a good product feeding end. The good product feeding end is connected to a downwardly inclined good product feeding track along the conveying direction of the conveyor belt. The defective product feeding end can rotate around the good product feeding end in a vertical plane and is guided by the inclined defective product feeding track. Several equally spaced rotatable arc-shaped baffles are provided on the feeding track to prevent contact between two adjacent eggs that have been detected as good products.

[0010] The discharge assembly includes a transfer adsorption gun located at the end of the good product unloading track, which adsorbs and transfers eggs that are detected as good products onto the conveyor belt.

[0011] Furthermore, the first identification component includes multiple adsorption guns arranged side by side, and multiple ultrasonic generators, detection tanks, rollers, cameras, material distribution plates, good product unloading tracks, and transfer adsorption guns are correspondingly provided, and each material distribution plate can rotate independently, and multiple material distribution plates are guided together to a defective product unloading track; each good product unloading track is provided with multiple arc-shaped baffles.

[0012] Furthermore, the first identification component includes a mounting plate installed on the frame, the mounting plate having a fixing post, the first identification component also includes a fixing plate, the fixing plate having a track groove, the fixing post being engaged in the track groove, the fixing plate being rotatably connected to a drive plate via a rotating shaft, the drive plate being driven by a first cylinder, when the first cylinder drives the fixing plate to perform a vertical linear motion, the fixing plate rotates under the action of the fixing post, and drives the adsorption gun to rotate.

[0013] Furthermore, the adsorption gun adsorbs the egg to be tested from both sides of the ultrasonic generator at an angle.

[0014] Furthermore, the bottom of the material distribution plate is connected to a servo motor via a multi-section linkage, and the good product unloading end of the material distribution plate is connected to the good product unloading track via a rotating shaft.

[0015] Furthermore, the good product feeding track is provided with multiple screening slots, and each arc-shaped baffle corresponds to two screening slots. The arc-shaped baffle sequentially includes a first arc-shaped segment, a first connecting segment, a second arc-shaped segment, a second connecting segment, and a third arc-shaped segment. The first arc-shaped segment bends upward along the conveyor belt's conveying direction, and the second arc-shaped segment bends downward along the conveyor belt's conveying direction. The first connecting segment and the second connecting segment are also arc-shaped. The bottom of the second connecting segment is stuck in the previous screening slot, and the third arc-shaped segment passes through the next screening slot. After an egg that is detected as good product rolls onto the first arc-shaped segment, the third arc-shaped segment lifts up and blocks the eggs behind it.

[0016] Compared with existing technologies, the significant advantages of this solution are:

[0017] This solution employs a more rational and ingenious structural design, enabling simultaneous internal ultrasonic testing and external image detection of eggs. The entire process is fully automated and requires no manual labor, achieving efficient and highly accurate automatic egg identification. Attached Figure Description

Detailed Implementation

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] like Figure 1-6 As shown, the automatic egg identification device of the present invention includes a frame 1, a conveyor belt 2 and an identification station 3 arranged along the conveying direction of the conveyor belt 2 on the frame 1.

[0029] Specifically, the identification station 3 includes a first identification component 31, a second identification component 32, a feeding component 33, and a discharging component 34 arranged sequentially.

[0030] The first identification component 31 includes a mounting plate 311 mounted on a frame 1. A fixing post 312 and an independent first cylinder 313 are provided on the mounting plate 311. The first identification component 31 also includes a fixing plate 314 with a track groove 315. The fixing post 312 is engaged in the track groove 315. The fixing plate 314 is rotatably connected to a drive plate 316 via a rotating shaft. The drive plate 316 is connected to the first cylinder 313 via a transmission connection. When the first cylinder 313 drives the fixing plate 314 to perform a vertical linear motion, the fixing plate 314 will rotate due to the limiting effect of the fixing post 312. Figure 7-9 The figures shown are schematic diagrams of the fixed plate 314 at different times during the rotation process.

[0031] A horizontal detection plate 317 is provided on the fixed plate 314. Multiple adsorption guns 319, arranged in pairs, are located on both sides of the detection plate 317. The adsorption guns 319 can adsorb eggs by creating a vacuum. An ultrasonic generator 318 is also provided on the detection plate 317. The generator head of the ultrasonic generator 318 is located between the pairs of adsorption guns 319, and it can perform ultrasonic testing on the eggs adsorbed by the adsorption guns 319. In this embodiment, there are five sets of adsorption guns 319, and correspondingly five ultrasonic generators 318, meaning that five eggs can be adsorbed simultaneously.

[0032] As shown in the diagram, after ultrasonic testing is completed, the detection plate 317 rotates with the fixed plate 314, thereby transferring the ultrasonically tested egg to the second identification component 32 by the adsorption gun 319.

[0033] The second identification component 32 includes multiple horizontal detection slots 321, five of which are present in this embodiment. Each detection slot 321 includes an inlet end 3211 and an outlet end 3212. The outlet end 3212 has two sets of rollers 322 with a gap between them. The rollers 322 closest to the outlet end 3212 are adjustable in horizontal position, thus adjusting the gap between them. The suction gun 319 releases the ultrasonically tested egg at the inlet end 3211. The released egg rolls through the outlet end 3212 and finally falls into the gap between the two sets of rollers 322. At this time, the camera 323 in the second identification component 32 captures an image of the egg's appearance and sends the image to the integrated controller, which then determines whether the egg is defective or good.

[0034] The feeding assembly 33 includes a distribution plate 331 located below two sets of rollers 322. The distribution plate 331 includes a defective product feeding end 3311 and a good product feeding end 3312. The good product feeding end 3312 is connected to an inclined downward-facing good product feeding track 332 via a rotating shaft along the conveying direction of the conveyor belt 2. The bottom of the distribution plate 331 is connected to a servo motor via a multi-section connecting rod. Through the action of the servo motor, the defective product feeding end 3311 can rotate around the good product feeding end 3312 in a vertical plane. The defective product feeding end 3311 is guided by the inclined defective product feeding track 333. In this embodiment, there are five good product feeding tracks 332 and one defective product feeding track 333. The five distribution plates 331 are all guided by this one defective product feeding track 333. Therefore, by controlling the gap between the two sets of rollers 322, the inspected eggs can fall from between the rollers 322 onto the sorting plate 331. If the egg is detected as defective, the defective discharge end 3311 is tilted in the opposite direction to the good product discharge track 332, so that the egg rolls from the defective discharge end 3311 onto the defective discharge track 333 to complete the discharge. If the egg is detected as good, the servo motor controls the sorting plate 331 to rotate, so that the defective discharge end 3311 is raised, and the falling egg can roll onto the good product discharge track 332.

[0035] The good product feeding track 332 is provided with several equally spaced rotatable arc-shaped baffles 334, and also has multiple screening troughs 335, with each arc-shaped baffle 334 corresponding to two screening troughs 335. Specifically, the arc-shaped baffle 334 sequentially includes a first arc-shaped segment 3341, a first connecting segment 3342, a second arc-shaped segment 3343, a second connecting segment 3344, and a third arc-shaped segment 3345. The first arc-shaped segment 3341 bends upward along the conveying direction of the conveyor belt 2, and the second arc-shaped segment 3343 bends downward along the conveying direction of the conveyor belt 2. The first connecting segment 3342 and the second connecting segment 3344 are also arc-shaped. The bottom of the second connecting segment 3344 is stuck in the previous screening trough 335, and the third arc-shaped segment 3345 passes through the next screening trough 335. After the eggs that are detected as good quality roll onto the first arc-shaped segment 3341, the third arc-shaped segment 3345 will lift up and block the eggs behind. In this embodiment, each good quality feeding track 332 is provided with five arc-shaped baffles 334, which can block five eggs at the same time.

[0036] The discharge assembly 34 includes a transfer adsorption gun 341 located at the end of the good product unloading track 332. Its movement is the same as that of the adsorption gun 319, and it can adsorb and transfer the eggs that are detected as good products onto the conveyor belt 2. Thus, the box that was originally used to place the eggs to be adsorbed by the adsorption gun 319 can move with the conveyor belt 2 to the discharge assembly 34, and a group of eggs that are detected as good products can be re-boxed.

[0037] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
