Description

Technical Field

[0001] This utility model relates to egg testing equipment, and in particular to an egg conveyor belt damage detection device. Background Technology

[0002] Egg farms produce a large number of eggs daily. After collection and cleaning, these eggs undergo further inspection to remove broken eggs before being packed for sale. Currently, egg breakage is primarily assessed by shining a strong light on the eggs. As eggs on a conveyor belt pass through the light source, workers observe the surface for cracks and remove any broken eggs. However, existing inspection equipment operates on a fixed position on the conveyor belt, meaning inspectors can typically only observe the upper half of the egg, making it difficult to detect the lower half and often resulting in missed eggs. Therefore, designing a device capable of comprehensively detecting egg breakage to improve inspection accuracy is clearly essential. Utility Model Content

[0003] The purpose of this invention is to provide an egg conveyor belt breakage detection device to solve the problems of false detection and missed detection in existing egg breakage detection methods.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An egg conveyor belt breakage detection device, including

[0006] support;

[0007] The drive shaft assembly includes two rotatable drive shafts mounted at both ends of a bracket. Drive wheels A are coaxially mounted on both ends of the drive shafts located inside the bracket. One of the drive shafts drives and connects to a motor A.

[0008] The conveyor belt has two parallel belts wound around the drive wheel A;

[0009] A rotating shaft assembly has multiple sets of equally spaced rotating shafts arranged on two conveyor belts. The rotating shaft assembly includes a rotating shaft that is rotatably mounted on the conveyor belt. At least one end of the rotating shaft extends outside the conveyor belt and is coaxially provided with a friction wheel. The distance between two adjacent rotating shafts is less than the diameter of an egg.

[0010] A drive component is disposed on one side of the bracket and contacts the friction wheel when the rotating shaft assembly passes by, so as to drive the rotating shaft assembly to rotate;

[0011] The lighting components are positioned between the supports and at the same level as the drive components to provide strong light to the eggs passing overhead.

[0012] Preferably, the rotating shaft is provided with a plurality of constraint tubes, which are equally spaced along the axial direction of the rotating shaft. The constraint tubes are in the shape of a waist drum to form an elliptical groove for placing an egg between two front and rear constraint tubes.

[0013] Preferably, the constraint tube is made of silicone.

[0014] Preferably, the driving component includes two rotatable drive wheels B disposed inside the bracket. The two drive wheels B are located on both sides of the lighting component. A friction belt is wound around the two drive wheels B, and the friction belt is in contact with the friction wheels. One of the two drive wheels B is driven and connected to a motor B.

[0015] Preferably, the bracket is also provided with an image recognition mechanism, which is located directly above the light assembly. The image recognition mechanism has a gripping component on its discharge side, which is electrically connected to the image recognition mechanism to grip and identify broken eggs.

[0016] Preferably, the gripping component includes a guide rail spanning above the support, a mover is mounted on the guide rail, the lower end of the mover is connected to a mounting plate, a plurality of telescopic cylinders corresponding one-to-one with the elliptical grooves on the conveyor belt are evenly distributed on the bottom of the mounting plate, a flexible suction cup is provided at the end of the telescopic rod of the telescopic cylinder, and a negative pressure pump is provided on the mounting plate, the negative pressure pump being connected to the flexible suction cup.

[0017] Preferably, the gripping component further includes a placement rack.

[0018] Compared with the prior art, the beneficial effects of this utility model are: when the egg passes the position of the light component, the drive component drives the rotating shaft component to rotate, thereby driving the egg to rotate above the light component. As the egg rotates, the bottom of the egg, which is difficult to observe, rotates to the top, so as to facilitate the staff or image recognition equipment to perform damage detection on the egg.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figures 1-6The illustrated egg conveyor belt breakage detection device includes a support frame 1, on which a set of drive shaft assemblies 2 are mounted. Each drive shaft assembly 2 includes two drive shafts 21, which are respectively mounted at both ends of the support and rotatably connected to it. Drive wheels A are coaxially mounted on the two ends of the drive shafts located inside the support, and one of the drive shafts extends out to the outer end of the support and is coaxially connected to a motor A23. When motor A rotates, the drive shaft connected to it rotates as the drive shaft. It should be noted that a conveyor belt 3 is wound around the drive wheels A of the two drive shafts, and the two conveyor belts are arranged in parallel. Several rotating shaft assemblies 4 are mounted on the conveyor belts, and these rotating shaft assemblies are evenly spaced to form a placement slot for holding eggs. It should be noted that the rotating shaft assembly 4 in this solution includes a rotatable rotating shaft 41 mounted on two conveyor belts 3. At least one end of the rotating shaft extends out of the conveyor belt, and a friction wheel 42 is coaxially connected to the extended end. This friction wheel is driven by a drive assembly 5 located on the inner side of the support, so that the rotating shaft 41 can rotate under the drive of the drive assembly. As the rotating shaft rotates, the egg placed between the two rotating shafts is driven by the rotating shaft and rotates slowly, thus ensuring that the egg can be fully illuminated when passing through the area located in the same segment as the drive assembly 5, thereby finding the broken parts that are not easily visible on the bottom of the egg.

[0030] It should be noted that in this design, several constraint tubes 42 are also fitted onto the rotating shaft 41, and these constraint tubes are arranged at equal intervals along the axial direction of the rotating shaft. Furthermore, each constraint tube is shaped like a waist drum, so that the constraint tubes on two adjacent rotating shafts form an elliptical groove for placing the eggs, thereby ensuring the stability of the eggs' position on the conveyor belt.

[0031] Based on the above embodiments, it is preferable that the constraint tube in this solution is made of soft silicone. Furthermore, it should be noted that silicone can increase the friction between the silicone and the egg, ensuring the stability of the egg's flipping as it passes over the light assembly.

[0032] It should also be noted that in the above scheme, the driving component 5 includes two transmission wheels B51 disposed on the inner side of the bracket. These two transmission wheels B are rotatably connected to the bracket, and one end of one transmission wheel B extends to the outside of the bracket. The output shaft of a motor B is coaxially connected to the extended transmission wheel B so as to drive the transmission wheel B to rotate. It should be noted that a friction belt 52 is also wound around the two transmission wheels B. After being driven by the transmission wheels B, the friction belt drives the friction wheel in contact with it to rotate synchronously.

[0033] Furthermore, it's important to understand that while the aforementioned structure allows workers to identify areas on the bottom of eggs that were previously difficult to detect, reducing the risk of missed or incorrect inspections, manual inspection remains inefficient. To improve efficiency, an image recognition mechanism 7 can be installed on the support 1, positioned directly above the lighting assembly 6. This mechanism takes images of the eggs illuminated by the light and identifies any damage in the subsequent photos, quickly identifying problematic eggs. To further enhance efficiency, a gripping assembly 8 is also installed on the discharge side of the image recognition mechanism 7. This gripping assembly is electrically connected to the image recognition mechanism 7 to quickly pick out identified broken eggs.

[0034] Specifically, the aforementioned gripping component 8 includes a guide rail 81 spanning above the support frame. A movable device 82 capable of moving along the guide rail is mounted on this rail. A mounting plate 83 is connected to the lower end of the movable device. Several telescopic cylinders 84, corresponding one-to-one with the elliptical grooves on the conveyor belt, are evenly distributed on the bottom of the mounting plate. A flexible suction cup 85 is mounted at the end of the telescopic rod of each telescopic cylinder. Simultaneously, a negative pressure pump 86 is mounted on the upper surface of the mounting plate. This negative pressure pump is connected to the flexible suction cup via a conduit, enabling the downward-moving flexible suction cup to pick up broken eggs.

[0035] It should be added that, in order to facilitate the acceptance of the picked-out broken eggs, the gripping component in this solution also includes a placement rack 87.

[0036] Working Principle: Eggs are carried by a conveyor belt to a position above the lighting assembly. An image recognition mechanism then takes an initial photograph of the egg and identifies any broken eggs, transmitting this information to the gripping assembly. The conveyor shaft assembly then stops for 3-5 seconds, before resuming operation and rotating the rotating shaft assembly. As the rotating shaft assembly rotates, the eggs on the conveyor belt are driven to flip up and down. After the eggs are in position, the image recognition mechanism takes another photograph, identifies any broken eggs, and transmits this information to the gripping assembly. The drive shaft assembly then resumes operation, bringing the identified eggs to a position below the gripping assembly. A telescopic cylinder extends within the gripping assembly, placing a flexible suction cup over the broken egg. A negative pressure pump then activates to suction the egg and remove it from the conveyor belt. Finally, the broken egg is placed on a rack for further centralized processing.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
