Description

Technical Field

[0001] This utility model belongs to the field of egg sorting technology, specifically an egg sorting mechanism based on optical sorting. Background Technology

[0002] Eggs, as a nutritious and affordable food, have a huge consumer market worldwide. From everyday home cooking to large-scale production in the food industry, the demand for eggs continues to grow. Ensuring the uniformity and safety of egg quality and achieving efficient and precise sorting are crucial in the production, processing, and distribution of eggs.

[0003] Patent CN214555413U discloses an automatic sorting device for an egg production line, comprising several sorting areas, a main control board, and a conveyor belt, several inductive screening devices, and several sorting devices connected to the main control board. The inductive screening devices and sorting devices are mounted above the conveyor belt, with the sorting devices positioned near the feeding end of the conveyor belt. The several sorting areas are spaced apart on one side of the conveyor belt, with each sorting area connected to the side of the conveyor belt. This invention uses inductive screening devices to sort eggs from largest to smallest, simplifying operation and avoiding errors from manual sorting. Simultaneously, infrared sensors detect and identify eggs remaining on the conveyor belt, transmitting signals to the main control board to control the sorting devices to push the eggs to the corresponding sorting areas, thus achieving automatic sorting.

[0004] However, the aforementioned automatic sorting device on an egg production line still has the following shortcomings:

[0005] The aforementioned device transports eggs via a planar conveyor belt, which can easily lead to multiple eggs being placed side by side on the conveyor belt. This makes it difficult for the detection and sorting mechanism to accurately sort the target eggs into the appropriate sorting area. Furthermore, the eggs may roll around during transport, increasing the possibility of collision and breakage. Therefore, we propose an egg sorting mechanism based on optical sorting. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides an egg sorting mechanism based on optical sorting, which effectively solves the problems of existing devices that transport eggs through a planar conveyor belt, which easily leads to multiple eggs being placed side by side on the conveyor belt, thus making it impossible for the detection and sorting mechanism to accurately sort the target eggs into the appropriate sorting area, and the eggs rolling around randomly during transport, increasing the possibility of collision and breakage.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an egg sorting mechanism based on optical sorting, comprising a base frame, a drive frame fixedly mounted at the top of the base frame, a roller conveyor belt inside the drive frame, a number of egg bodies placed on the surface of the roller conveyor belt, a support fixedly mounted on one side of the top of the drive frame, an optical detection component in the middle of the support, a set of auxiliary mechanisms symmetrically arranged on the inner wall of the drive frame, a sorting component on one side of the drive frame, and a set of temporary storage mechanisms symmetrically arranged on the lower right side of the sorting component.

[0008] Preferably, the auxiliary mechanism includes an electric push rod, which is fixed to the inner surface of the drive frame, and the movable end of the electric push rod is connected to a limit plate.

[0009] Preferably, the sorting assembly includes an inclined frame, which is fixed to one side of the drive frame. A rubber pad is adhered to the inclined surface of the inclined frame. A T-shaped shaft runs through the middle of the inclined frame and the rubber pad. A motor is connected to one end of the T-shaped shaft. A positioning plate is attached to one side of the motor. A sorting rod is connected to the other end of the T-shaped shaft. Several ball bearings are evenly engaged inside the sorting rod on the side near the T-shaped shaft.

[0010] Preferably, the sorting rod is fitted with a protective rubber sleeve on its outer side, the sorting rod forms a rotating structure with the motor through a T-shaped shaft, the motor is threadedly connected to the positioning plate, and the positioning plate is fixedly connected to the inclined frame.

[0011] Preferably, two-thirds of the ball is movably engaged inside the sorting bar, and the ball can rotate freely inside the sorting bar.

[0012] Preferably, the temporary storage mechanism includes a temporary storage box, which is placed on one side of the top of the base frame. A locking rod is fixed to the outside of the temporary storage box, and a triangular buffer pad is adhered to the inside of the temporary storage box.

[0013] Preferably, the base frame surface has a slot that matches the locking rod, and the temporary storage box forms a locking structure with the base frame through the locking rod.

[0014] Preferably, the temporary storage box on the left is a premium product box, and the temporary storage box on the right is a substandard product box.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By setting up a roller conveyor belt, it is possible to effectively ensure that only a single egg is placed between adjacent rollers, avoiding the situation where multiple eggs are placed side by side. When an egg is transported by the roller conveyor belt to the area below the optical detection component, a set of electric push rods effectively drive a set of limit plates to move closer, thereby moving the egg directly under the optical detection component, improving the detection effect. The signal collected by the optical detection component is transmitted to the control system, and the quality grade of the egg is identified through image processing algorithms.

[0017] 2. When the egg is found to be qualified, the control system controls the motor to rotate 45 degrees counterclockwise, thereby driving the T-shaped shaft and sorting rod to rotate 45 degrees counterclockwise, facilitating the sliding of the egg to the left side of the inclined frame until it slides into the left temporary storage box. When the egg is found to be unqualified, the control system controls the motor to rotate 45 degrees clockwise, thereby driving the T-shaped shaft and sorting rod to rotate 45 degrees clockwise, facilitating the sliding of the egg to the right side of the inclined frame until it slides into the right temporary storage box. The protective rubber sleeves on the rubber pads and the outer side of the sorting rods can reduce the possibility of collision damage to the egg. Several ball bearings on the bottom side of the sorting rods can reduce the friction between the sorting rods and the rubber pads.

[0018] 3. The inclined surface of the triangular buffer pad on the inside of the temporary storage box connects with the inclined surface of the rubber pad, which facilitates secondary cushioning of the egg. Attached Figure Description

[0027] Please see Figure 1-4 An egg sorting mechanism based on optical sorting includes a base frame 1, a drive frame 2 fixed at the top of the base frame 1, a roller conveyor belt 3 inside the drive frame 2, several egg bodies 4 placed on the surface of the roller conveyor belt 3, a bracket 5 fixed on one side of the top of the drive frame 2, an optical detection component 6 in the middle of the bracket 5, a set of auxiliary mechanisms 7 symmetrically arranged on the inner wall of the drive frame 2, the auxiliary mechanisms 7 including electric push rods 701, the electric push rods 701 fixed on the inner surface of the drive frame 2, the movable end of the electric push rods 701 connected to a limit plate 702, and a sorting component 8 on one side of the drive frame 2. A set of temporary storage mechanisms 9 are symmetrically arranged on the lower right side of component 8. By setting up roller conveyor belt 3, it can effectively ensure that only a single egg body 4 is placed between adjacent rollers, avoiding the situation where multiple egg bodies 4 are placed side by side. When an egg body 4 is transported to the area below the optical detection component 6 by following the roller conveyor belt 3, a set of electric push rods 701 effectively drives a set of limit plates 702 to move closer, thereby moving the egg body 4 directly below the optical detection component 6, improving the detection effect. The signal collected by the optical detection component 6 is transmitted to the control system, and the quality grade of the egg body 4 is identified by the image processing algorithm.

[0028] The sorting assembly 8 includes a slant frame 801, which is fixed to one side of the drive frame 2. A rubber pad 802 is adhered to the inner slanted surface of the slant frame 801. A T-shaped shaft 803 passes through the middle of the slant frame 801 and the rubber pad 802. One end of the T-shaped shaft 803 is connected to a motor 804. A positioning plate 805 is attached to one side of the motor 804. The other end of the T-shaped shaft 803 is connected to a sorting rod 806. A protective rubber sleeve is fitted on the outer side of the sorting rod 806. The sorting rod 806 and the motor 804 form a rotating structure via the T-shaped shaft 803. The motor 804 and the positioning plate 805 are threaded together, and the positioning plate 805 and the slant frame 801 are fixedly connected. Several balls 807 are evenly engaged inside the sorting rod 806 near the T-shaped shaft 803. Furthermore, two-thirds of the balls 807 are movably engaged inside the sorting rod 806. The inner side of the sorting rod 806 rotates freely. When the egg body 4 is found to be qualified, the control system controls the motor 804 to rotate counterclockwise by 45 degrees, thereby driving the T-shaped shaft 803 and the sorting rod 806 to rotate counterclockwise by 45 degrees. This facilitates the egg body 4 after inspection to slide to the left side of the inclined frame 801 until it slides into the left temporary storage box 901. When the egg body 4 is found to be unqualified, the control system controls the motor 804 to rotate clockwise by 45 degrees, thereby driving the T-shaped shaft 803 and the sorting rod 806 to rotate clockwise by 45 degrees. This facilitates the egg body 4 after inspection to slide to the right side of the inclined frame 801 until it slides into the right temporary storage box 901. The protective rubber sleeves on the outer side of the rubber pad 802 and the sorting rod 806 can reduce the possibility of collision damage to the egg body 4. Several ball bearings 807 set on the bottom side of the sorting rod 806 can reduce the friction between the sorting rod 806 and the rubber pad 802.

[0029] The temporary storage mechanism 9 includes a temporary storage box 901, which is placed on one side of the top of the base frame 1. The left temporary storage box 901 is a premium product box, and the right temporary storage box 901 is a defective product box. A locking rod 902 is fixed to the outside of the temporary storage box 901. Furthermore, a locking groove matching the locking rod 902 is opened on the surface of the base frame 1. The temporary storage box 901 and the base frame 1 form a locking structure through the locking rod 902. A triangular buffer pad 903 is glued to the inside of the temporary storage box 901. The inclined surface of the triangular buffer pad 903 on the inside of the temporary storage box 901 is connected to the inclined surface of the rubber pad 802, which facilitates secondary buffering of the egg body 4.
