Description

Technical Field

[0001] This application relates to the field of food processing equipment technology, and more specifically, to a bone detection X-ray machine production line for slaughterhouses. Background Technology

[0002] In the large-scale processing of poultry, especially in the slaughtering and processing of chicken, non-food foreign objects such as metal fragments, bone fragments, glass, or high-density plastics may be mixed into the product. These foreign objects not only pose a direct physical risk to consumers, such as causing oral or digestive tract injuries, but may also trigger a widespread crisis of trust in food safety, leading to significant economic losses and damage to brand reputation for enterprises. Therefore, implementing efficient and reliable foreign object detection at the end of the production line is a core element in ensuring product quality. Currently, the industry mainly uses metal detectors and X-ray detection systems as detection methods. Metal detectors are relatively inexpensive, but are limited to identifying metallic foreign objects and cannot handle the detection needs of non-metallic impurities such as bone fragments, stones, or glass. X-ray detection technology, on the other hand, utilizes the principle of penetrating imaging based on differences in material density, and can effectively identify various types of foreign objects, including metals, bones, hard plastics, and glass, and is gradually becoming standard equipment in high-standard meat processing lines. However, existing X-ray detection systems still have significant shortcomings in practical applications in poultry processing. Regarding detection accuracy, chicken products often have blood, ice chips, meat scraps, or fat layers adhering to their surface. These impurities form interfering images in X-ray images that are highly similar to tiny foreign objects (especially low-density cartilage or fine bone), making it difficult for the system to distinguish between real foreign objects and surface contaminants. This results in a high frequency of false alarms or missed detections, severely weakening the reliability of the detection results. In terms of production line integration, most systems simply install the X-ray module isolated on the conveyor belt. The feeding, detection, and sorting processes lack coordinated design, resulting in low automation. Before and after detection, manual operation is often required for product loading / unloading or re-inspection of suspected products, which not only slows down production and increases manpower input but also introduces the risk of human error and cross-contamination. Regarding post-detection processing, when the system identifies products containing foreign objects, traditional sorting devices are slow to react and lack positioning accuracy, often resulting in qualified products being incorrectly rejected or problematic products not being intercepted in time, affecting overall sorting efficiency and accuracy. In terms of production line layout, the spatial distribution of various functional units such as the feeding area, cleaning area, inspection area and diversion area is loose, resulting in a long production line with an excessively large footprint. The material flow path is tortuous and inefficient, making it difficult to adapt to the space constraints and transformation needs of the existing workshop, thus restricting the improvement of production efficiency. Summary of the Invention

Detailed Implementation

[0022] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0023] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] In the large-scale processing of poultry, X-ray inspection systems face image interference problems caused by impurities on the product surface. Blood, ice chips, or meat scraps can form image features similar to tiny foreign objects in X-ray images, causing false alarms or missed detections. At the same time, poor coordination between processes in the production line and insufficient automation require manual intervention before and after inspection. In addition, the reaction speed and accuracy of rejection devices are insufficient, and the layout of the production line is unreasonable, affecting the overall sorting efficiency and reliability.

[0025] For example, at the end of a chicken processing line, when products pass through the X-ray inspection area at normal speed, the blood and ice particles attached to the surface create high-density shadows in the X-ray image, which are misidentified by the system as bone fragments, triggering frequent false alarms. Operators need to stop the production line for manual re-inspection, causing production to be interrupted. At the same time, products containing foreign objects are not effectively intercepted due to the delayed response of the rejection mechanism, and are mixed into the qualified product stream, resulting in a decrease in the accuracy of subsequent sorting.

[0026] If the above problems are not resolved, the accuracy of testing will continue to decline, increasing food safety risks; production line efficiency will decrease due to human intervention, leading to increased labor costs; the possibility of cross-contamination will increase; and corporate reputation will be damaged, potentially triggering a consumer trust crisis and economic losses.

[0027] Furthermore, to address the impact of product surface condition on testing accuracy, impurities must be effectively removed before testing; in this regard, the spatial layout of each functional module of the production line needs to be optimized to improve material flow efficiency.

[0028] Please see Figures 1 to 7 As shown, this application proposes a bone detection X-ray machine production line for slaughterhouses, including a U-shaped support frame 1. Both the front and rear ends of the U-shaped support frame 1 are provided with feeding conveyor belts 11. The middle of the U-shaped support frame 1 is provided with a cleaning component 2 for cleaning foreign objects on the surface of chicken meat, and the cleaning component 2 is located between the front and rear feeding conveyor belts 11. The rear of the U-shaped support frame 1 is connected to an discharge conveyor belt 3. The front end of the discharge conveyor belt 3 is fitted with an X-ray detection module, and the discharge port of the discharge conveyor belt 3 is provided with a diversion mechanism 4.

[0029] For ease of understanding, the following explains some key terms in this embodiment: U-shaped support frame: This component forms the main framework of the entire production line. Its U-shaped structure provides stable support and space for the installation and integration of other functional modules. Its design aims to ensure the structural stability and operational safety of the production line in industrial production environments.

[0030] Feeding conveyor belt: This component is used to transport meat products (such as chicken products) to be processed from the front end of the production line or the previous process to the cleaning area of ​​this production line. It is usually driven by a motor and achieves smooth and continuous material transfer through a continuous conveyor belt.

[0031] Cleaning component: This component is located between the feeding conveyor belts, and its core function is to remove adhering substances from the surface of meat products, such as blood, ice chips, meat scraps, fat, or other impurities that may affect the accuracy of subsequent X-ray inspection. Pre-cleaning effectively reduces interference in X-ray images and improves inspection accuracy.

[0032] Discharge conveyor belt: This component transports cleaned meat products from the cleaning area to the X-ray inspection area and ultimately guides them to the sorting mechanism. It works in conjunction with the loading conveyor belt to ensure the smooth flow of meat products on the production line.

[0033] X-ray inspection module: This component is the core inspection unit of the production line. It uses X-rays to penetrate meat products and generate transparent images based on the density differences of different materials. By analyzing these images, foreign objects inside or on the surface of the meat products, such as bone fragments, metal, and glass, can be identified and located. This module typically integrates an X-ray source and a detector.

[0034] The sorting mechanism: This component is located at the end of the discharge conveyor belt. Its function is to separate qualified meat products from unqualified meat products containing foreign objects based on the detection results of the X-ray inspection module. Automated sorting can improve production efficiency and ensure that only products that meet quality standards enter subsequent stages.

[0035] This embodiment provides a bone detection X-ray machine production line for slaughterhouses, the main technical features of which and their implementation methods are as follows: The production line includes a U-shaped support frame. This U-shaped support frame, serving as the skeleton of the entire equipment, can be implemented in various structural forms. For example, it can be constructed from welded steel or aluminum alloy profiles, connected by bolts or welding to form a stable U-shaped structure to support the various functional modules on the production line. Another approach is to adopt a modular design, assembling prefabricated standardized U-shaped units for easy transportation and rapid on-site setup. The robustness of this support frame is crucial for ensuring the long-term stable operation of the equipment.

[0036] The U-shaped support frame has feeding conveyor belts at both its front and rear ends. These conveyor belts are responsible for introducing the chicken products to be processed into the production line. One implementation method is to use a traditional flat belt conveyor, with a motor-driven roller that rotates the belt to smoothly transport the products. Another implementation method is to use a modular mesh belt conveyor, which has good water permeability and easy cleaning, making it suitable for meat processing environments. The operating speed of these conveyor belts can be adjusted according to production needs to adapt to different capacity requirements.

[0037] The U-shaped support frame features a cleaning component in its center for removing foreign matter from the chicken surface, positioned between the front and rear feeding conveyors. This cleaning component aims to remove impurities from the surface of the chicken product. One method is to use a mechanical brushing device, where rotating brush rollers contact the product surface to physically remove adhering substances. Another method is to use a high-pressure airflow blowing device, which sprays high-speed airflow through nozzles to blow away loose impurities from the product surface. A water washing spray device can also be used to rinse the product surface with sprayed water to remove blood and debris. These cleaning methods can be used individually or in combination for better cleaning results.

[0038] A discharge conveyor belt is connected to the rear of the U-shaped support frame. This discharge conveyor belt receives the cleaned chicken products and transports them to the subsequent inspection stage. Its implementation is similar to that of the loading conveyor belt, and it can use a flat belt or a modular mesh belt. The length and width of the discharge conveyor belt can be adapted to the size of the X-ray inspection module and the product flow rate to ensure continuous and stable material transport.

[0039] The front end of the discharge conveyor belt is equipped with an X-ray detection module. This module is the core component for detecting foreign objects in the flowing chicken products. One implementation method is to use a single-energy X-ray source and a linear array detector, where X-rays penetrate the product and acquire a transmission image. Another implementation method is to use dual-energy X-ray technology, which uses X-rays of different energies to acquire two images, thus better distinguishing between organic and inorganic matter. This module is typically integrated with a lead shield to ensure operator safety.

[0040] The discharge conveyor belt is equipped with a diversion mechanism at its outlet. This mechanism is used to classify products based on inspection results. One implementation method is to use a pneumatic pusher; when a defective product is detected, the pusher quickly moves to remove the product from the main conveyor belt to the defective product collection area. Another implementation method is to use a flap-type diverter, which guides products to different discharge paths by controlling the opening and closing direction of the flaps. Lateral levers or swing arm mechanisms can also be used to remove defective products from the main production line. The response speed and operational accuracy of these diversion mechanisms are crucial to ensuring sorting efficiency.

[0041] The following example will provide a more detailed explanation of the above technical solution: Imagine a large chicken slaughtering and processing plant where pre-cut chicken products need to be inspected for bones and other foreign objects to ensure product quality and food safety. Traditional inspection methods suffer from problems such as interference from surface impurities, low automation, and low sorting efficiency.

[0042] This embodiment provides a bone detection X-ray machine production line for slaughterhouses that effectively solves the aforementioned problems. Specifically, when a batch of chicken products enters the production line from the previous process, it is first placed on a feeding conveyor belt at the front end of a U-shaped support frame. This feeding conveyor belt smoothly transports the chicken products to the middle of the production line. Before entering the X-ray detection area, the products pass through a cleaning unit located in the middle of the U-shaped support frame. For example, this cleaning unit can be a brushing unit composed of multiple rotating brushes combined with high-pressure airflow nozzles. When the chicken products pass through this cleaning unit, the rotating brushes physically remove impurities such as blood, meat scraps, and ice chips from the product surface, while the high-pressure airflow further blows away loose attachments. This pre-cleaning step significantly reduces the interference of product surface impurities on the X-ray image, thereby improving the accuracy of subsequent X-ray detection and effectively solving the problem that detection accuracy is greatly affected by the product condition.

[0043] The cleaned chicken products are then received by a discharge conveyor belt and continue to move forward. This conveyor belt precisely feeds the products into an X-ray inspection module mounted at its front end. In this module, X-rays penetrate the chicken products, and a detector acquires real-time images. This X-ray inspection module can identify bone fragments, metal foreign objects, or high-density plastics inside the product. After inspection, the products continue to move along the discharge conveyor belt to a diversion mechanism at their discharge port.

[0044] When the X-ray inspection module detects a foreign object in a chicken product, it immediately generates a non-conforming signal. Upon receiving this signal, the diversion mechanism quickly takes action, for example, by using a pneumatic pusher to remove the non-conforming product from the main conveyor belt and guide it to a dedicated non-conforming product collection box. For products that pass the inspection, the diversion mechanism remains inactive, allowing them to continue along the main conveyor belt into the conforming product collection area or the next process step.

[0045] Thus, the entire production line achieves continuous automation from feeding, pre-cleaning, X-ray inspection to diversion. The U-shaped support frame provides a compact and stable structure, enabling efficient integration of various functional modules and solving the problems of suboptimal production line layout and insufficient integration. The placement of cleaning components solves the problem of inspection accuracy, while the close cooperation between the X-ray inspection module and the diversion mechanism solves the problem of low post-inspection processing efficiency. The entire process requires no manual intervention, significantly improving production efficiency, reducing labor costs, and avoiding the risks of human error and cross-contamination.

[0046] Based on the above examples, the technical solution of this embodiment demonstrates significant technical contributions. In the prior art, poultry X-ray inspection systems often suffer from decreased detection accuracy due to surface contaminants (such as blood and meat scraps), easily leading to false alarms or missed detections. This embodiment achieves pretreatment of the chicken product surface by setting a cleaning component before the X-ray inspection module. For example, in the above example, the combined cleaning of a rotating brush and high-pressure airflow effectively removes interfering impurities. Compared with the prior art of directly X-raying untreated products, this greatly improves the accuracy and reliability of X-ray inspection.

[0047] Furthermore, existing production lines often lack integration, with processes such as feeding, inspection, and sorting potentially requiring manual assistance or experiencing poor coordination, leading to low production efficiency. The production line in this embodiment organically integrates a U-shaped support frame, feeding conveyor belt, cleaning components, discharge conveyor belt, X-ray inspection module, and sorting mechanism into a continuous and automated processing flow. For example, in this example, the product enters the feeding conveyor belt, passes through the cleaning component, then enters the X-ray inspection via the discharge conveyor belt, and is finally automatically sorted by the sorting mechanism, achieving seamless integration throughout the entire process. This highly integrated automated design significantly improves production efficiency, reduces labor costs, and effectively avoids the potential contamination risks associated with human operation compared to the existing technology's independent module operation and manual intervention model.

[0048] Furthermore, existing technologies may suffer from slow response times and inaccurate rejection when handling foreign products. The sorting mechanism in this embodiment is located at the discharge port of the conveyor belt and can quickly and accurately separate defective products based on signals from the X-ray detection module. For example, in this example, the rapid response of the pneumatic push rod ensures that defective products are promptly and accurately removed from the main production line. Compared to traditional manual sorting or slow-responding mechanical rejection devices, this significantly improves sorting efficiency and accuracy, thereby guaranteeing the quality of the final product.

[0049] In summary, this embodiment effectively solves multiple technical problems in the prior art, such as insufficient detection accuracy, low automation, low diversion efficiency, and suboptimal production line layout, by introducing a pre-cleaning component, realizing a highly integrated automated production line, and configuring an efficient and accurate diversion mechanism. It provides a more advanced, efficient, and reliable foreign object detection solution for the poultry processing industry.

[0050] In other embodiments, this application proposes a bone detection X-ray machine production line for slaughterhouses, whose basic structure includes a U-shaped support frame, a feeding conveyor belt, a cleaning unit, an unloading conveyor belt, an X-ray detection module, and a diversion mechanism. However, in practical applications, the X-ray detection module and diversion mechanism alone cannot fully achieve accurate identification, positioning, and efficient diversion of foreign objects in meat products. Especially when faced with complex and varied meat product shapes and foreign object types, the lack of intelligent image analysis and decision-making mechanisms may lead to low detection efficiency and high misjudgment rates, thereby affecting product quality and production efficiency.

[0051] In response, this application further proposes an X-ray detection module positioned along the discharge conveyor belt to acquire X-ray images of meat products flowing through its detection area; an image processing and intelligent recognition module communicatively connected to the X-ray detection module to process the X-ray images in real time, identify and locate foreign objects in the images based on deep learning algorithms, and output a non-conforming signal containing the location information of the foreign objects; a diversion mechanism positioned downstream of the X-ray detection module along the discharge conveyor belt and communicatively connected to the image processing and intelligent recognition module to divert the meat based on the non-conforming signal and the location information of the foreign objects; and a central control module electrically connected to the feeding conveyor belt, the discharge conveyor belt, the X-ray detection module, the image processing and intelligent recognition module, and the diversion mechanism to coordinate the synchronous operation of each module.

[0052] The X-ray inspection module is positioned along the discharge conveyor belt, and its main function is to acquire X-ray images of the meat products flowing through its inspection area. This module can be implemented using various technologies. For example, it could be an industrial-grade X-ray inspection system containing an X-ray source and an X-ray detector, emitting X-rays that penetrate the meat products and are received by the detector to form a transmission image. Alternatively, it could be a high-resolution X-ray imaging device optimized for the food industry, providing clear images of the internal structure for analysis by subsequent image processing and intelligent recognition modules. The image processing and intelligent recognition module communicates with the X-ray inspection module to process the X-ray images in real time and identify and locate foreign objects in the images based on deep learning algorithms, ultimately outputting a non-compliance signal containing the location information of the foreign objects. This module could also be a high-performance industrial computer with a built-in graphics processing unit (GPU) to accelerate the inference process of the deep learning model. The deep learning algorithm running internally can be a convolutional neural network (CNN), a region convolutional neural network (R-CNN), or a YOLO (You Only Look Once) object detection algorithm. By training on a large number of images of meat products with and without foreign objects, it can accurately identify foreign objects such as bones, metal, and glass, and precisely pinpoint their location in the image. The diversion mechanism is located downstream of the X-ray detection module along the discharge conveyor belt and is communicatively connected to the image processing and intelligent recognition module. It performs diversion operations based on non-compliance signals and foreign object location information. This mechanism can be a pneumatic pusher system; when it receives a non-compliance signal and foreign object location information, the pneumatic pusher moves rapidly at a specific position, pushing the meat product containing the foreign object off the main conveyor belt. Alternatively, it can use a robotic arm, a flip-up plate, or a multi-channel conveyor belt to precisely guide non-compliance products to the waste collection area based on the location and type of the foreign object, while qualified products continue to be conveyed. The central control module is electrically connected to the feeding conveyor belt, discharging conveyor belt, X-ray detection module, image processing and intelligent recognition module, and diversion mechanism to coordinate the synchronous operation of each module. This module can be a programmable logic controller (PLC) or an industrial control computer, which monitors and controls the operating status of each sub-module in real time through preset programs and communication protocols. It is responsible for receiving non-conforming signals from the image processing and intelligent recognition module and precisely controlling the timing and position of the diversion mechanism based on these signals. Simultaneously, it ensures that the operating speed of the feeding and discharging conveyors matches the detection and diversion process, thereby achieving automated, efficient, and collaborative operation of the entire production line.

[0053] This application's solution organically integrates an X-ray detection module, an image processing and intelligent recognition module, a diversion mechanism, and a central control module to construct an intelligent foreign object detection and diversion system. Specifically, meat products first enter the production line via a feeding conveyor belt. After initial foreign object removal by a cleaning unit, they are transported to the X-ray detection module via an output conveyor belt. The X-ray detection module acquires real-time X-ray images of the meat products as they flow through its detection area. These images are then transmitted to the image processing and intelligent recognition module, which uses a pre-trained deep learning algorithm to perform high-speed analysis of the images, accurately identifying and locating any bones or other foreign objects that may be present. Once a foreign object is detected, the image processing and intelligent recognition module immediately generates a non-compliance signal containing information on the type and precise location of the foreign object. The central control module, acting as the "brain" of the entire system, receives and processes the non-compliance signal from the image processing and intelligent recognition module in real time, and accurately calculates the timing and target location of the diversion mechanism based on this signal and the foreign object's location information. Subsequently, the central control module sends instructions to the sorting mechanism, driving it downstream of the discharge conveyor belt, after the X-ray detection module, to separate meat products containing foreign objects from the main production line, thus automatically removing defective products. Simultaneously, the central control module also coordinates the operating speeds of the feeding and discharging conveyors, ensuring the smoothness and efficiency of the entire detection, identification, and sorting process. Through this closely collaborative mechanism, this solution enables automated, high-precision, real-time detection and sorting of foreign objects in meat products, significantly improving the intelligence level of the production line and product quality control capabilities.

[0054] The following is a specific example. As a concrete implementation, the X-ray inspection module can utilize an industrial X-ray inspection device, model "Safeline X33," equipped with a high-sensitivity linear array detector, capable of acquiring X-ray images with a resolution of 0.4 mm at 30 frames per second. The image processing and intelligent recognition module can be an embedded vision system equipped with an NVIDIA Jetson AGX Xavier development board, running a YOLOv5 deep learning model trained on the PyTorch framework. This model, trained on tens of thousands of X-ray images containing foreign objects such as chicken bones and metal fragments, can identify and locate foreign objects in images with an accuracy of over 98% within 100 milliseconds. The diversion mechanism can consist of a set of pneumatic pushers installed on both sides of the discharge conveyor belt. Each pusher is controlled by a solenoid valve. When the image processing and intelligent recognition module sends a non-compliance signal and foreign object location information, the central control module calculates the corresponding pusher number and action sequence, and drives the corresponding solenoid valve, causing the pusher to push the non-compliance meat product away from the main conveyor belt within 0.1 seconds. The central control module can use a Siemens S7-1500 series PLC, which exchanges data and controls commands at high speed with the X-ray detection module, image processing and intelligent recognition module and the shunt mechanism through Profinet industrial Ethernet, ensuring precise synchronization of all links in the production line.

[0055] Through the above technical solution, this application effectively solves the problems of low efficiency, high labor costs, insufficient detection accuracy, and susceptibility to human factors in the foreign object detection and sorting process of traditional slaughterhouse production lines. Utilizing the internal perspective images obtained by the X-ray detection module, combined with the powerful analytical capabilities of the image processing and intelligent recognition module based on deep learning algorithms, non-contact, high-precision, real-time identification and positioning of foreign objects inside meat products can be achieved, significantly reducing the missed detection rate and false judgment rate. The sorting mechanism automatically and accurately removes foreign objects based on the intelligent recognition results, avoiding the tediousness and uncertainty of manual sorting. The coordinating role of the central control module ensures seamless connection and efficient operation of all links in the entire production line, thereby greatly improving the automation level of the production line and product quality control capabilities, ensuring food safety, and reducing production costs.

[0056] In some embodiments described above, an X-ray inspection module is used to acquire X-ray images of meat products, and an image processing and intelligent recognition module is used for foreign object identification. However, in actual production, slaughterhouses often need to process various types and forms of meat products, such as bone-in chicken and boneless chicken. These different types of meat products may exhibit different characteristics in X-ray images. If only a single foreign object identification model is used, it may be difficult to maintain a high-precision identification effect for all meat products, thereby affecting the accuracy and efficiency of the inspection.

[0057] In response, this application further proposes that the image processing and intelligent recognition module has a built-in multi-product model database, which can call the corresponding pre-trained foreign object recognition model for different types of meat products.

[0058] The multi-product model database is a collection of foreign object recognition models stored and managed internally by the image processing and intelligent recognition module. Its concept lies in providing a structured storage space for storing deep learning models optimized and trained for different types of meat products. This database can be implemented as a file system directory structure, where each directory corresponds to a type of meat product and contains the corresponding model file and related configuration parameters; alternatively, it can be an embedded database system, such as SQLite, used to store model metadata and paths to model files, thereby enabling more flexible model management and querying. Simultaneously, it can invoke the corresponding pre-trained foreign object recognition model for different types of meat products. This capability means that the image processing and intelligent recognition module dynamically selects and loads the most suitable foreign object recognition model for the currently processed meat product type for image analysis. Implementation methods can include: operators manually selecting the type of meat product on the current production line via a control interface; upon receiving the instruction, the image processing and intelligent recognition module loads the corresponding pre-trained model from a multi-product model database; or, through data interaction with automated identification systems (such as barcode scanners or RFID readers) or production planning systems on the production line, automatically acquiring information on the current type of meat product, thereby triggering automatic model switching. These pre-trained foreign object recognition models are typically built based on deep learning techniques (such as convolutional neural networks) and have been trained and optimized using a large amount of X-ray image data of specific meat products to identify foreign objects such as bone fragments, metal, and plastic that may be present in the product.

[0059] This application's solution improves the adaptability and accuracy of foreign object detection by embedding a multi-product model database within the image processing and intelligent recognition module. This database enables the module to call upon pre-trained foreign object recognition models for different types of meat products. Specifically, when a slaughterhouse uses a bone detection X-ray machine to process different types of meat products on a production line, the image processing and intelligent recognition module no longer relies on a single general model. Instead, it precisely selects and loads a pre-trained foreign object recognition model from its built-in multi-product model database based on the specific type of meat product. Because this pre-trained model is optimized for specific meat product characteristics (such as bone density, tissue structure, and common foreign object types), it can more accurately distinguish the structure of the meat product itself from potential foreign objects when processing X-ray images of such products, significantly improving the accuracy of foreign object recognition and location. This mechanism allows the entire detection system to flexibly adapt to changes in the types of meat products on the production line, avoiding false or missed detections due to insufficient model generalization ability, and ensuring food safety standards for different types of meat products.

[0060] As a specific implementation method, the image processing and intelligent recognition module can pre-store foreign object recognition models for different meat product types such as "boneless chicken breast," "bone-in chicken thigh," and "chicken wings." For example, when the production line is processing "boneless chicken breast," the central control module can send a command to the image processing and intelligent recognition module, indicating that the current product type is "boneless chicken breast." Upon receiving this command, the image processing and intelligent recognition module will load a foreign object recognition model specifically trained for "boneless chicken breast" from its built-in multi-product model database. This model may be particularly adept at identifying small cartilage or metallic foreign objects because "boneless chicken breast" typically does not contain large bones. When the production line switches to "bone-in chicken thigh," the system will correspondingly load the foreign object recognition model for "bone-in chicken thigh." This model may focus more on distinguishing the normal shape of the chicken thigh bone from abnormal bone fragments or external foreign objects to avoid misidentifying normal bone structures as foreign objects. The multi-product model database can be stored using a file system. Each model and its configuration file are stored in a folder named after the product type. The image processing and intelligent recognition module loads the corresponding model parameters and weights by reading the configuration file.

[0061] Through the aforementioned technical solution, the X-ray foreign object detection production line in slaughterhouses can dynamically call upon the most suitable pre-trained foreign object recognition model based on different types of meat products. This enables the system to significantly improve the accuracy and reliability of foreign object recognition when processing diverse meat products, effectively reducing false alarm and false negative rates. Because the model is optimized for specific products, it better adapts to the X-ray image characteristics of different meat products, thus ensuring consistently high standards of food safety testing even in production environments with frequent product switching, thereby improving the overall production line efficiency and product quality.

[0062] In some other embodiments, this application proposes a bone detection X-ray machine production line for slaughterhouses, which includes a cleaning component for removing foreign matter from the surface of chicken meat. However, in actual production, the size and shape of chicken meat may vary, and the types and degrees of adhesion of surface foreign matter also differ. This makes it difficult for traditional fixed or simply adjustable cleaning components to effectively and thoroughly remove surface foreign matter from chicken meat of different sizes, potentially leading to incomplete cleaning or damage to the chicken meat.

[0063] Please continue reading. Figures 1 to 4 As shown, this application further proposes that the cleaning component 2 includes a support rod 21. The support rod 21 is provided at both the front and rear ends of the upper surface of the two vertical plates of the U-shaped support frame 1. A strip-shaped groove 22 is provided on the inner side of each support rod 21. A synchronous motor (not shown) is installed in the strip-shaped groove 22. A screw (not shown) is connected to the output end of the synchronous motor. A moving block (not shown) is spirally sleeved on the screw. A lifting plate 23 is connected between the moving blocks at the front and rear ends. A connecting rod 24 is provided at both the front and rear ends between the lifting plates 23 at the left and right ends. A fixing block 25 is fixed at both the left and right ends of the connecting rod 24. A first rotating shaft 26 is rotatably arranged between 5. A U-shaped swing frame 27 is arranged on the first rotating shaft 26. A drive motor 28 for driving the first rotating shaft 26 to rotate is arranged on the fixed block 25. A fixed sleeve 5 is sleeved on the crossbar of the U-shaped swing frame 27. A support plate 51 is arranged on the lower surface of the fixed sleeve 5. Cleaning brushes 52 are arranged around the lower surface of the support plate 51. An air blowing pipe (not shown) is arranged in the middle of the lower surface of the support plate 51. Multiple high-pressure air blowing ports (not shown) are opened at equal intervals on the lower surface of the air blowing pipe. An air supply pipe 53 for supplying air to the air blowing pipe is embedded in the middle of the crossbar of the U-shaped swing frame 27.

[0064] Specifically, the cleaning component is used to remove foreign objects adhering to the surface of the chicken, such as bone fragments, feathers, and ice crystals. Various methods can be used, including physical contact, airflow purging, and liquid rinsing, to ensure the chicken surface is clean and provides a good foundation for subsequent X-ray inspection. The support rod, as the skeleton structure of the cleaning component, provides mechanical support and positioning. It can be a solid or hollow metal rod, such as a stainless steel rod, an aluminum alloy rod, or a high-strength engineering plastic rod. A groove is formed on the inner side of the support rod to accommodate and guide the moving parts. It can be a U-shaped groove, a V-shaped groove, or a rectangular groove, formed by milling, casting, or extrusion. The synchronous motor is a motor capable of precisely controlling speed and position. It can be a stepper motor, a servo motor, or a permanent magnet synchronous motor, used to drive the screw rotation. The screw converts rotational motion into linear motion and can be a trapezoidal threaded rod, a ball screw, or a regular threaded rod. The moving block is helically fitted onto the screw and moves linearly along the screw. It can be a slider with internal threads, usually made of wear-resistant materials such as engineering plastics or metals, and lined with a self-lubricating material. The lifting platform connects the moving blocks at both ends to form an overall lifting platform. It can be a metal plate or composite material plate, connected by welding, bolts, or integral molding. The connecting rod connects the lifting plates at both ends and fixes the fixed blocks. It can be a solid or hollow metal rod, such as a stainless steel round or square rod. The fixed block is fixed to the connecting rod and is used to rotate the first rotating shaft. It can be a metal block with bearing seats, fixed to the connecting rod by bolts or welding. The first rotating shaft rotates between the fixed blocks and carries the shaft of the U-shaped swing frame. It can be a solid or hollow metal shaft, such as a stainless steel shaft, supported by bearings. The U-shaped swing frame is set on the first rotating shaft, forming a U-shape, and is used to carry the cleaning tool frame. It can be a welded or integrally molded metal frame, such as a stainless steel square or round tube. The drive motor drives the first rotating shaft to rotate and can be a DC motor, AC motor, stepper motor, or servo motor. The fixing sleeve is fitted onto the crossbar of the U-shaped swing frame and is used to fix the support plate. It can be a cylindrical or square sleeve made of metal or engineering plastic, fixed by bolts or clips. A support plate, fixed to the lower surface of the fixing sleeve, is used to mount the cleaning brush and air blowing pipe. It can be a metal plate, plastic plate, or composite material plate. The cleaning brushes, arranged around the lower surface of the support plate, are used to physically wipe the chicken surface. They can be nylon brushes, silicone brushes, pig bristle brushes, etc., with adjustable bristle hardness. The air blowing pipe, located in the center of the lower surface of the support plate, is a conduit for providing high-pressure airflow. It can be a metal or plastic pipe with a smooth interior and high pressure resistance. High-pressure air blowing ports are orifices evenly spaced on the lower surface of the air blowing pipe for spraying high-pressure airflow. They can be circular holes, slit-shaped holes, or nozzles, and their diameter and shape can be designed according to airflow requirements. An air supply pipe, embedded in the middle of the crossbar of the U-shaped swing frame, is used to supply air to the air blowing pipe. It can be a flexible or rigid air pipe, such as a PU pipe, PE pipe, or stainless steel pipe, and connects to an external air source.

[0065] The solution presented in this application achieves precise and efficient cleaning of foreign matter on the surface of chicken through the ingenious design of the aforementioned cleaning component. When the chicken enters the cleaning area via the feeding conveyor belt, a synchronous motor in the strip-shaped groove within the support rod drives a screw to rotate. The screw drives a moving block to move along its spiral path, thereby enabling the lifting plate connected to the moving block to achieve precise vertical lifting. This lifting function allows the overall height of the cleaning component to be flexibly adjusted according to chicken of different sizes and thicknesses, ensuring that the cleaning brush and air pipe maintain the optimal contact distance and pressure with the chicken surface, thus avoiding damage to the chicken due to excessive contact or incomplete cleaning due to insufficient contact. Simultaneously, the connecting rod provides lateral support between the lifting plates, and a fixed block fixed to it is rotatably equipped with a first rotating shaft. A U-shaped swing frame mounted on the first rotating shaft can swing around the first rotating shaft through the drive motor. This swing function allows the cleaning brush and air pipe below the U-shaped swing frame to clean the chicken surface at multiple angles and directions. Especially for irregularly shaped chicken or stubborn foreign matter, the swinging motion achieves more comprehensive coverage and more thorough removal. The support plate serves as the mounting base for the cleaning brush and air blowing pipe, ensuring their stability and positioning during cleaning. The cleaning brush removes attached foreign objects by physically wiping the chicken surface; while the air blowing pipe, through multiple high-pressure air nozzles evenly spaced on its lower surface, sprays high-pressure airflow to blow away loose foreign objects or areas inaccessible to the brush. The air supply pipe is embedded in the middle of the crossbar of the U-shaped swing frame, providing a stable high-pressure air source for the air blowing pipe. This adjustable, multi-functional, and composite cleaning mechanism significantly improves the thoroughness and adaptability of foreign object removal from the chicken surface, providing cleaner meat products for subsequent X-ray inspection modules, thereby greatly improving the accuracy and reliability of bone detection.

[0066] The following is a specific example: The support rod can be made of a 50mm diameter stainless steel round tube, and the strip groove can be a rectangular groove with a width of 20mm and a depth of 15mm, machined by a CNC milling machine. The synchronous motor can be a 100W rated power stepper motor, such as a NEMA 23 stepper motor. The screw can be a 16mm diameter ball screw with a lead of 5mm. The moving block can be a self-lubricating engineering plastic slider with a flange nut, such as POM material. The lifting plate can be an 8mm thick aluminum alloy plate, connected to the moving block by bolts. The connecting rod can be a 30mm diameter solid stainless steel round rod. The fixing block can be a cast aluminum alloy part with an integrated ball bearing seat. The first rotating shaft can be a 25mm diameter 304 stainless steel shaft. The U-shaped swing frame can be welded from a 25mm x 25mm stainless steel square tube. The drive motor can be a 50W rated power DC geared motor, such as a motor with a worm gear reducer. The fixing sleeve can be a PTFE sleeve with an inner diameter matching the outer diameter of the U-shaped swing frame crossbar, and fixed with set screws. The support plate can be made of 5mm thick food-grade PP board. The cleaning brushes can be nylon brushes with bristle length of 30mm and medium bristle hardness, arranged in a ring. The air blowing pipe can be a stainless steel pipe with an inner diameter of 10mm. The high-pressure air blowing port can be a 2mm diameter circular nozzle, evenly spaced along the air blowing pipe at 20mm intervals. The air supply pipe can be a 1.0MPa pressure-resistant PU air pipe, connected to an external high-pressure air pump.

[0067] Through the above technical solution, the cleaning component of this application can achieve precise and efficient cleaning of foreign objects on the surface of chicken. The lifting plate allows the height of the cleaning component to be precisely adjusted according to different sizes of chicken, ensuring that the cleaning brush and air pipe maintain the optimal distance and contact pressure with the chicken surface, avoiding incomplete cleaning or damage to the chicken. The swing function of the U-shaped swing frame allows the cleaning tool to clean the chicken surface at multiple angles and directions, especially for irregularly shaped chicken or stubborn foreign objects, achieving more comprehensive coverage and more thorough removal through swinging. The combination of the cleaning brush and the high-pressure air nozzle achieves a dual cleaning effect of physical wiping and airflow sweeping, effectively removing various foreign objects such as bone fragments, feathers, and ice crystals. This adjustable, multi-functional, and composite cleaning mechanism significantly improves the thoroughness and adaptability of cleaning foreign objects on the chicken surface, providing cleaner meat products for the subsequent X-ray inspection module, thereby greatly improving the accuracy and reliability of bone detection, reducing false detection and false negative rates, and ensuring product quality and production efficiency.

[0068] In some other embodiments, this application proposes a bone detection X-ray machine production line for slaughterhouses. In some of the embodiments described above, the bone detection X-ray machine production line for slaughterhouses has a cleaning component installed in the middle of a U-shaped support frame, and the cleaning component is positioned between the front and rear feeding conveyor belts. However, when chicken products are transferred from the feeding conveyor belt to the cleaning component area, there may be problems such as unstable transmission, inaccurate positioning, or low transmission efficiency, affecting the accuracy and efficiency of subsequent cleaning and inspection.

[0069] Please continue reading. Figures 1 to 3 , Figure 6 As shown, this application further proposes that support blocks 6 are provided in the middle of the inner sides of the two vertical plates of the U-shaped support frame 1, and a second rotating shaft 61 is rotatably arranged between the support blocks 6 at the left and right ends. The second rotating shaft 61 is arranged between the front and rear feeding conveyor belts 11. Multiple sets of transfer conveyor components 62 that are connected to the feeding conveyor belt 11 and the discharging conveyor belt 3 are arranged at equal intervals on the second rotating shaft 61. The transfer conveyor component 62 includes a first conveyor belt 63 and a second conveyor belt 64. Multiple first conveyor belts 63 are arranged at equal intervals on the second rotating shaft 61. A first telescopic cylinder 65 is provided on the upper surface of the left and right support plates of the first conveyor belt 63. The second conveyor belt 64 is provided at the end of the telescopic rod of the first telescopic cylinder 65.

[0070] The support blocks are structural components used to fix and support other parts. They can be metal, plastic, or composite material blocks, and are fixed to the inner center of the two vertical plates of the U-shaped support frame through welding, bolting, or integral molding, providing a stable mounting base for the second rotating shaft. The second rotating shaft is a shaft-like component used to transmit rotational motion and support the transfer conveyor. It is usually made of high-strength metal materials, such as stainless steel or alloy steel, and is rotatably mounted between the support blocks via bearings. Its rotation can be driven by a motor or through linkage with other parts of the production line. The transfer conveyor is a device used to smoothly and efficiently transfer materials between different conveyor belts. It can be a combination of belt, chain, or roller conveyor mechanisms, ensuring that chicken products smoothly transition from the feeding conveyor belt to the discharging conveyor belt and pass through the cleaning area. The first conveyor belt is part of the transfer conveyor and is used to carry and transport the chicken products. It can be a flat belt, mesh belt, or modular plastic belt, usually made of wear-resistant and corrosion-resistant materials, and its continuous or intermittent movement is achieved through a drive device. The second conveyor belt is another part of the transfer conveyor system, working in conjunction with the first conveyor belt to further carry and transport chicken products. It can have a similar structure to the first conveyor belt, or it can be a conveyor belt with specific gripping or positioning functions. The first telescopic cylinder is an actuator that converts the pressure energy of compressed air into mechanical energy to achieve linear reciprocating motion. It can be a single-acting or double-acting cylinder, and it controls the air pressure to extend and retract the telescopic rod. Its function is to adjust the height or position of the second conveyor belt so as to accurately align with the feeding and discharging conveyor belts.

[0071] This application's solution provides a stable mounting base and drive source for the transfer conveyors by setting support blocks in the middle of the inner sides of the two vertical plates of a U-shaped support frame and rotating a second shaft between the support blocks. Multiple sets of transfer conveyors, including a first conveyor belt and a second conveyor belt, are evenly spaced on the second shaft. When chicken products are transferred from the feeding conveyor belt to the middle of the U-shaped support frame, the first conveyor belt receives the products and performs initial transport. To ensure a smooth transition of the products from the first conveyor belt to the discharge conveyor belt and through the cleaning area, first telescopic cylinders are installed on the upper surfaces of the left and right support plates of the first conveyor belt, with the ends of their telescopic rods connected to the second conveyor belt. By controlling the extension and retraction of the first telescopic cylinders, the height and position of the second conveyor belt can be precisely adjusted, allowing for seamless docking with the feeding and discharge conveyors. This design ensures that chicken products are stably carried and transported as they pass through the cleaning area, avoiding potential impacts, drops, or mispositioning issues that may occur when switching between different conveyor belts. This guarantees the effectiveness of the cleaning unit in removing foreign objects from the chicken surface and lays the foundation for the subsequent X-ray inspection module to obtain high-quality X-ray images. Overall, the introduction of this transfer conveyor optimizes the material transport path in the middle section of the production line, improves the smoothness and reliability of the transport, and thus enhances the overall operational efficiency and detection accuracy of the bone detection X-ray machine production line in the slaughterhouse.

[0072] The following is a concrete example: Two L-shaped steel support blocks can be welded to the inner center of the two vertical plates of the U-shaped support frame. Between these two support blocks, a 50mm diameter stainless steel second shaft is rotatably mounted via bearing seats installed on the support blocks. This second shaft can be driven by a servo motor through a gear reduction mechanism to achieve precise speed and position control. Five sets of transfer conveyors are installed at equal intervals on the second shaft. The first conveyor belt of each set can be a 150mm wide food-grade PU belt, with independent drive and driven rollers at both ends. The drive rollers are linked to the second shaft via a chain. A 50mm stroke miniature cylinder is installed on the upper surface of each of the left and right support plates of the first conveyor belt as the first telescopic cylinder. The end of the telescopic rod is connected to a small platform on which the second conveyor belt is mounted. The second conveyor belt can be made of the same material and width as the first conveyor belt, but its length is slightly shorter and overlaps with the end portion of the first conveyor belt. When the height of the second conveyor belt needs to be adjusted, the air source is controlled to supply or exhaust air to the first telescopic cylinder, causing the telescopic rod to extend or retract, thereby raising or lowering the second conveyor belt to achieve precise height matching with the front and rear conveyor belts.

[0073] Through the above technical solution, in the X-ray bone detection production line of a slaughterhouse, chicken products can achieve stable, efficient, and precise material transfer from the feeding conveyor belt to the cleaning area and subsequent discharge conveyor belt. The transfer conveyor on the second rotating shaft, especially the design of adjusting the second conveyor belt through the first telescopic cylinder, effectively solves the problems of impact, jamming, or positioning deviation that may occur when products transition between different conveyor belts, significantly improving the continuity and stability of material transfer. This not only ensures that the cleaning unit can fully and accurately clean foreign objects from the surface of the chicken, but also provides the X-ray detection module with a stable and accurately positioned product to be inspected, thereby improving the overall operating efficiency, detection accuracy, and product qualification rate of the production line.

[0074] In other embodiments, this application proposes an X-ray inspection line for bone detection in slaughterhouses. The X-ray inspection module in a real slaughterhouse environment often faces challenges from adverse factors such as dust, moisture, and temperature fluctuations. These environmental conditions may cause contamination, corrosion, or performance instability of the precision components of the X-ray inspection module, thereby affecting its detection accuracy and service life.

[0075] Please continue reading. Figures 1 to 3 As shown, this application further proposes that the X-ray detection module be installed in a sealed protective chamber 7, which is equipped with a positive pressure dustproof system and a temperature and humidity control system.

[0076] The sealed protective chamber refers to a closed structure that effectively isolates the X-ray detection module from the external environment. It primarily serves to physically prevent external contaminants such as dust, moisture, and debris from entering the X-ray detection module, while also isolating it to some extent from the effects of external temperature fluctuations. For example, the protective chamber can be made of corrosion-resistant materials such as stainless steel or high-strength plastics, and its airtightness can be ensured through welding, bolting, or sealing gaskets. It can also be designed with an openable maintenance door, but the maintenance door must reliably seal during normal operation. The positive pressure dustproof system refers to a system that continuously injects clean air into the protective chamber, making the internal air pressure slightly higher than the external ambient air pressure. Its function is to use the pressure difference to prevent external air containing dust and moisture from seeping into the protective chamber through tiny gaps, thereby achieving dust protection for the X-ray detection module. The system can include an air filter, a fan, and corresponding ductwork and pressure sensors. The fan delivers filtered clean air into the protective chamber, and the pressure sensor monitors the pressure inside the chamber and feeds back to the control unit to adjust the fan speed and maintain a stable positive pressure. Alternatively, an independent air purification unit with a HEPA filter can be used to directly supply air into the protective chamber, with an exhaust port to maintain positive pressure. The temperature and humidity control system is used to control the temperature and humidity inside the protective chamber, aiming to ensure that the X-ray detection module operates within its optimal operating temperature and humidity range. This avoids performance degradation, accelerated component aging, or condensation caused by excessively high or low temperatures or humidity, thereby extending equipment life and ensuring detection accuracy. This system can include a heater, a cooler (such as a small air conditioner or thermoelectric cooler), a humidity sensor, and corresponding control circuitry. The sensor monitors the temperature and humidity inside the chamber in real time, and the control circuitry activates heating or cooling, dehumidification or humidification functions according to preset parameters. Alternatively, an integrated industrial-grade precision air conditioner or dehumidifier can be used, directly installed outside or inside the protective chamber, to precisely control the environment inside the chamber through air circulation.

[0077] The proposed solution creates a controlled microenvironment by installing the X-ray detection module within a sealed protective chamber and incorporating a positive pressure dustproof system and a temperature and humidity control system within this chamber. The sealed chamber acts as the first physical barrier, isolating the X-ray detection module from dust, moisture, debris, and other contaminants that may be present in the slaughterhouse environment. Furthermore, the positive pressure dustproof system continuously supplies filtered clean air into the chamber, maintaining an internal pressure slightly higher than the external ambient pressure. This positive pressure effectively prevents unclean air from seeping in through tiny gaps or interfaces within the chamber, further enhancing the dustproof effect and ensuring the cleanliness of the X-ray detection module's interior. Simultaneously, the temperature and humidity control system monitors and actively adjusts the temperature and humidity within the chamber in real time, ensuring the X-ray detection module always operates within its optimal design range, preventing performance fluctuations, component aging, or condensation caused by harsh environmental conditions. This technical solution, combined with the X-ray detection module in a slaughterhouse bone detection X-ray machine production line, enables the X-ray detection module to operate stably and efficiently in harsh industrial environments. The sealed protective chamber, positive pressure dustproof system, and temperature and humidity control system work together to not only protect the X-ray detection module from physical damage and environmental pollution, but more importantly, they ensure the quality of X-ray imaging and the accuracy of image processing and intelligent recognition modules, thereby improving the reliability and accuracy of foreign object detection in meat products throughout the entire production line.

[0078] The following is a concrete example: the X-ray detection module can be installed in a sealed protective chamber welded from 304 stainless steel plates. All seams of the chamber are sealed with food-grade silicone sealant rings, and an access door with a sealing strip is provided. A positive pressure dustproof system can be integrated into the top of the chamber. This system includes a fan unit with a G4 pre-filter and an H13 high-efficiency filter. The fan unit delivers clean air into the chamber through ducts, and an adjustable exhaust valve is installed on the side wall of the chamber to maintain a positive pressure of 0.5-1.0 mm water column inside. Simultaneously, an industrial-grade small-scale temperature and humidity control unit can be installed inside the chamber. This unit monitors the internal environment in real time using built-in temperature and humidity sensors and automatically activates heating, cooling, or dehumidification functions based on preset temperature (e.g., 20-25 degrees Celsius) and humidity (e.g., 40%-60%RH) ranges to ensure the X-ray detection module always operates in a stable environment.

[0079] By installing the X-ray detection module within a sealed protective chamber and equipping it with a positive pressure dustproof system and a temperature and humidity control system, the aforementioned technical solution effectively addresses the impact of adverse factors such as dust, moisture, and temperature fluctuations in the slaughterhouse environment on the performance and lifespan of the X-ray detection module. The sealed protective chamber provides physical isolation, the positive pressure dustproof system prevents the intrusion of external contaminants, and the temperature and humidity control system maintains the module's optimal operating environment. This significantly improves the operational stability and detection accuracy of the X-ray detection module, reduces the failure rate and maintenance costs caused by environmental factors, and ensures that the X-ray machine production line for bone detection in slaughterhouses can continuously and reliably detect foreign objects in meat products, thereby enhancing food safety assurance.

[0080] In some other embodiments, this application proposes a bone detection X-ray machine production line for slaughterhouses, comprising a U-shaped support frame with feeding conveyor belts at both ends. A cleaning component for removing foreign matter from the chicken surface is located in the middle of the U-shaped support frame, positioned between the feeding conveyor belts. An output conveyor belt is connected to the rear of the U-shaped support frame, with an X-ray detection module fitted at its front end. A diversion mechanism is located at the output outlet of the output conveyor belt. However, in the bone detection X-ray machine production line for slaughterhouses, after meat products undergo X-ray detection, effective diversion of qualified and unqualified products is required. Improper design of the diversion mechanism may lead to confusion between qualified and unqualified products, or low diversion efficiency, affecting subsequent processing.

[0081] Please continue reading. Figures 1 to 3 , Figure 7 As shown, this application further proposes a diversion mechanism 4 including a U-shaped support base 41, which is disposed at the discharge port of the discharge conveyor belt 3. The front end of the U-shaped support base 41 is provided with a first diversion conveyor belt 42 for receiving unqualified chicken products, and the first diversion conveyor belt 42 is disposed below the discharge port of the discharge conveyor belt 3. The rear end of the U-shaped support base 41 is provided with a second diversion conveyor belt 43 for receiving qualified chicken products.

[0082] The diversion mechanism is a device used to separate different categories of items from the main conveyor line and guide them to different paths. It can be implemented, for example, through a robotic arm, pneumatic push rod, flap, or multiple branch conveyor belts. The U-shaped support is a structure with a U-shaped cross-section or U-shaped profile, used to provide support and accommodate other components. It can be made by bending and welding sheet metal, or integrally molded by casting, injection molding, etc., providing a stable mounting base and protection for the internal components of the diversion mechanism. The U-shaped support is located at the discharge port of the discharge conveyor belt, indicating its position at the end of the main discharge conveyor belt. It is a critical transition area for products leaving the main line, ensuring that the diversion mechanism can directly receive products unloaded from the discharge conveyor belt. The first diversion conveyor belt is used to transport specific categories of items (in this case, non-conforming chicken). It can be of various forms, such as belt conveyor, chain conveyor, or roller conveyor, driven by a motor to achieve continuous or intermittent conveying, separating non-conforming items from the main line and transporting them to a designated non-conforming item collection area. The first diversion conveyor belt is located below the discharge port of the discharge conveyor belt. This arrangement typically means that defective products, upon leaving the discharge conveyor belt, will fall directly into or be guided to the first diversion conveyor belt below by gravity or other means. The second diversion conveyor belt is used to transport another category of items (in this case, qualified chicken products). Similar to the first diversion conveyor belt, it can also be a belt type, chain plate type, roller type, etc. Driven by a motor, it separates qualified products from the main line and transports them to a designated qualified product collection area or the next processing stage.

[0083] The diversion mechanism of this application incorporates a U-shaped support as the overall frame, within which a first diversion conveyor belt for receiving defective products and a second diversion conveyor belt for receiving qualified products are cleverly configured, thereby achieving effective classification and conveying of meat products. Specifically, the U-shaped support is positioned at the discharge port of the discharge conveyor belt, serving as a transition area for products leaving the main line. When meat products are unloaded from the discharge conveyor belt, based on the judgment results of the X-ray detection module and the image processing and intelligent recognition module, defective products are guided to the first diversion conveyor belt located below the discharge port of the discharge conveyor belt, where they fall directly into the conveyor belt by gravity or other mechanical means and are conveyed away. Simultaneously, qualified products are guided to the second diversion conveyor belt located at the rear end of the U-shaped support and continue to be conveyed to subsequent processing stages. This structural design ensures that defective and qualified products are immediately physically separated after leaving the main line, avoiding confusion and ensuring their respective independent conveying paths. In this way, the sorting mechanism can efficiently and accurately separate different types of meat products, thus solving the problems of confusion or inefficiency that may exist in traditional sorting methods, and ensuring the smooth operation of the production line and the control of product quality.

[0084] The following is a concrete example illustrating the diversion mechanism. It may include a U-shaped support base welded from stainless steel sheets, fixedly installed below the discharge port of the discharge conveyor belt, with its opening facing upwards, completely covering the discharge port area. At the bottom front end of the U-shaped support base, a first belt-type diversion conveyor belt, with a width matching the discharge conveyor belt and a conveying direction perpendicular to it, can be installed to receive defective chicken falling from the discharge conveyor belt. The drive motor for this first diversion conveyor belt can be mounted on the side wall of the U-shaped support base. At the rear end of the U-shaped support base, a second diversion conveyor belt, with a height similar to the discharge conveyor belt and a conveying direction consistent with it, can be installed to smoothly receive qualified chicken and transport it to the next process. The drive motor for the second diversion conveyor belt can also be installed at a corresponding position on the U-shaped support base. When the X-ray inspection module identifies a defective product, it can be pushed into the first diversion conveyor belt below by a pneumatic pusher or flip-plate mechanism when the defective product reaches the discharge port; when a qualified product is identified, it is allowed to directly and smoothly transition to the second diversion conveyor belt.

[0085] Through the above technical solution, the diversion mechanism adopts a U-shaped support base as the integrated frame and clearly distinguishes the receiving paths for unqualified and qualified products. Unqualified products are received via the first diversion conveyor belt located below the discharge port of the main discharge conveyor belt, while qualified products are received via the second diversion conveyor belt located at the rear end of the U-shaped support base. This design allows for immediate and effective physical separation of meat products after they leave the main discharge conveyor belt, avoiding confusion between qualified and unqualified products and significantly improving the accuracy and efficiency of diversion. Simultaneously, the structure of the U-shaped support base provides a stable installation foundation and protection for the diversion mechanism, ensuring the reliability and continuity of the entire diversion process. This effectively solves the problem of incomplete or inefficient meat product diversion in X-ray bone detection lines used in slaughterhouses, guaranteeing product quality and a smooth production process.

[0086] In some embodiments described above in this application, a diversion mechanism is proposed, comprising a U-shaped support base with a first diversion conveyor belt at its front end for receiving defective chicken products and a second diversion conveyor belt at its rear end for receiving qualified chicken products. However, in actual operation, ensuring that the second diversion conveyor belt can flexibly and accurately connect with the discharge port of the discharge conveyor belt and adapt to position adjustments under different production needs is a problem that needs to be solved.

[0087] Please continue reading. Figures 1 to 3 , Figure 7As shown, this application further proposes that a fixing plate 44 is provided at the rear end of the inner bottom surface of the U-shaped support 41, and the fixing plate 44 is perpendicular to the horizontal plate of the U-shaped support 41. The fixing plate 44 is provided with a second telescopic cylinder 45 at both ends. Multiple guide rail grooves 46 are equally spaced in the middle of the inner bottom surface of the U-shaped support 41. The telescopic rod of the second telescopic cylinder 45 is provided with a sliding block 47 at the end. The lower surface of the sliding block 47 is provided with sliding protrusions (not shown) at both ends for embedding into the guide rail grooves 46. The upper surface of the sliding block 47 is provided with a second diversion conveyor belt 43, and the second diversion conveyor belt 43 is perpendicular to the first diversion conveyor belt 42. The second diversion conveyor belt 43 is located above the first diversion conveyor belt 42 and is connected to the discharge port of the discharge conveyor belt 3.

[0088] The fixing plate is a structural component inside the U-shaped support of the diversion mechanism. Its function is to provide a stable mounting base and support for subsequent moving parts. It is set perpendicular to the horizontal plate of the U-shaped support, ensuring structural stability and rational spatial layout, and providing a precise positioning surface for the installation of the second telescopic cylinder and guide rail groove.

[0089] The second telescopic cylinder is a linear actuator that uses compressed air to drive the piston rod to extend or retract, thereby achieving linear motion. In this design, it is used to provide a controllable push-pull force to drive the sliding block and its supported second diverter conveyor belt to move. It can be implemented using a single-acting or double-acting cylinder, precisely controlling the movement of the telescopic rod by controlling the on / off state or direction of the air pressure.

[0090] The guide groove is a structure on the inner bottom surface of the U-shaped support used to guide the movement of the sliding block. It provides a preset, low-friction path, ensuring that the sliding block maintains a stable and precise straight trajectory during movement. The guide groove can adopt various cross-sectional forms such as V-shaped grooves, U-shaped grooves, or rectangular grooves, and its material is usually a wear-resistant metal or engineering plastic.

[0091] The sliding block is an intermediate component connecting the second telescopic cylinder and the second diverting conveyor belt. It slides within the guide rail groove, bearing and transmitting the driving force of the second telescopic cylinder. The sliding protrusion on the lower surface of the sliding block engages with the guide rail groove, ensuring stable movement of the sliding block within the groove and preventing deflection or jamming. The sliding block is typically made of materials with good self-lubricating or wear-resistant properties, such as polyoxymethylene (POM), ultra-high molecular weight polyethylene (UHMW-PE), or a metal block with a sliding bearing.

[0092] The second diversion conveyor belt is a conveying device used to receive qualified chicken products. In this design, it is mounted on a sliding block, allowing it to move within a guide rail groove. It is positioned perpendicular to and above the first diversion conveyor belt; this layout optimizes space utilization and enables efficient separation of qualified and unqualified products. Through the movement of the sliding block, the second diversion conveyor belt precisely aligns with the discharge port of the discharge conveyor belt, ensuring smooth product transfer.

[0093] The solution of this application provides a stable mounting base for the second telescopic cylinder by setting a fixing plate at the rear end of the inner bottom surface of the U-shaped support seat of the diversion mechanism. The second telescopic cylinder, embedded at both ends, has its telescopic rod end connected to a sliding block. The sliding protrusion on the lower surface of the sliding block precisely engages with the guide rail groove in the middle of the inner bottom surface of the U-shaped support seat, ensuring that the sliding block moves smoothly along a preset trajectory within the guide rail groove. The second diversion conveyor belt is positioned on the upper surface of the sliding block. When the position of the second diversion conveyor belt needs adjustment, the central control module can control the telescopic movement of the second telescopic cylinder. The second telescopic cylinder drives the sliding block to slide within the guide rail groove, thereby causing the second diversion conveyor belt to move horizontally. This adjustable structure allows the second diversion conveyor belt to precisely align with the discharge port of the discharge conveyor belt, ensuring that qualified chicken products can be smoothly and undamagedly transferred from the discharge conveyor belt to the second diversion conveyor belt. Meanwhile, when the production line needs maintenance, cleaning, or processing of products of different specifications, the position of the second diversion conveyor can be flexibly adjusted to adapt to different operational needs, thereby improving the adaptability and ease of operation of the entire diversion mechanism.

[0094] For example, the rear end of the inner bottom surface of the U-shaped support can be fixed with a 5mm thick stainless steel plate, which is welded or bolted to the U-shaped support. A single-acting cylinder with a stroke of 100mm can be embedded at each end of the fixed plate as a second telescopic cylinder. The cylinder's air inlet is connected to an air source via a solenoid valve, and its on / off state is controlled by the central control module. Two parallel V-shaped guide grooves can be formed in the middle of the inner bottom surface of the U-shaped support. The guide grooves can be made of wear-resistant polyoxymethylene. The sliding block can be made of aluminum alloy, with a V-shaped sliding protrusion on its lower surface that matches the V-shaped guide groove. The upper surface of the sliding block is fixed with bolts to the second diversion conveyor belt. When the second diversion conveyor belt needs to be moved outward, the central control module issues a command, the solenoid valve opens, compressed air enters the second telescopic cylinder, pushing the telescopic rod to extend, causing the sliding block to slide outward along the guide groove until the second diversion conveyor belt is precisely aligned with the discharge port of the discharge conveyor belt. Conversely, when it is necessary to move inward, the solenoid valve closes, the cylinder resets, or it is driven in the reverse direction by a double-acting cylinder.

[0095] Through the above technical solution, a fixed plate is installed at the rear end of the inner bottom surface of the U-shaped support, and a second telescopic cylinder, guide rail groove, and sliding block are configured on this basis, enabling the second diversion conveyor belt to achieve precise and adjustable horizontal displacement. This design ensures that the second diversion conveyor belt can flexibly and accurately dock with the discharge port of the discharge conveyor belt, effectively solving the shortcomings of traditional fixed diversion mechanisms in terms of docking accuracy and adaptability. In addition, the second diversion conveyor belt is set perpendicular to and above the first diversion conveyor belt, further optimizing the spatial layout of the diversion mechanism, improving the operating efficiency and automation level of the entire production line, reducing the need for manual intervention, and thus improving the overall performance and reliability of the slaughterhouse bone detection X-ray machine production line.

[0096] In some other embodiments, this application proposes a bone detection X-ray machine production line for slaughterhouses, comprising a U-shaped support frame, with feeding conveyor belts at both ends of the U-shaped support frame, a cleaning component for removing foreign matter from the surface of chicken meat disposed in the middle of the U-shaped support frame, and the cleaning component being positioned between the front and rear feeding conveyor belts, and an output conveyor belt connected to the rear of the U-shaped support frame, with an X-ray detection module sleeved at the front end of the output conveyor belt, and a diversion mechanism disposed at the output outlet of the output conveyor belt. This diversion mechanism includes a U-shaped support base disposed at the output outlet of the output conveyor belt, a first diversion conveyor belt for receiving defective chicken meat disposed at the front end of the U-shaped support base, and the first diversion conveyor belt being positioned below the output outlet of the output conveyor belt, and a second diversion conveyor belt for receiving qualified chicken meat disposed at the rear end of the U-shaped support base.

[0097] In some embodiments described above in this application, the X-ray machine production line for detecting bone samples in slaughterhouses uses a diversion mechanism to divert unqualified meat products to a first diversion conveyor belt for collection. However, in actual production, if unqualified products continue to accumulate on the first diversion conveyor belt, it may cause the conveyor belt to become clogged, affecting the diversion efficiency and even requiring frequent manual cleaning, thereby reducing the automation level and continuity of the entire production line.

[0098] Please continue reading. Figures 1 to 3 As shown, this application further proposes that a discharge port 8 is provided on the right vertical plate of the U-shaped support 41, and the discharge port of the first diversion conveyor belt 42 is provided through the discharge port 8. A circulating conveyor belt 81 corresponding to the discharge port of the first diversion conveyor belt 42 is provided on the right side of the U-shaped support 41.

[0099] The U-shaped support has a discharge port on its right vertical plate. This discharge port, an opening on the side wall of the U-shaped support, provides a channel for the outward discharge of defective products carried by the first diversion conveyor belt. The discharge port can be rectangular or trapezoidal, or it can be a structure with a guide ramp to ensure smooth discharge of defective products from the U-shaped support. The discharge port of the first diversion conveyor belt extends through this discharge port, meaning that the end portion of the first diversion conveyor belt or its discharge end extends outside the U-shaped support through the discharge port. This arrangement ensures that defective products carried by the first diversion conveyor belt can be directly and effectively discharged from the U-shaped support, avoiding accumulation inside. For example, the end of the conveyor belt can slightly extend beyond the edge of the discharge port, or it can pass through via a connected chute structure. A circulating conveyor belt, corresponding to the discharge port of the first diversion conveyor belt, is located to the right of the U-shaped support frame. This circulating conveyor belt is a conveying device for receiving and transporting defective products discharged from the first diversion conveyor belt. It is positioned on the right side of the U-shaped support frame and precisely aligned in space with the discharge port of the first diversion conveyor to ensure that defective products can be seamlessly transferred from the first diversion conveyor to the circulating conveyor. This circulating conveyor can be a standalone belt conveyor, chain conveyor, or roller conveyor, and its function is to transport defective products to a designated location for further processing, such as returning them to the cleaning process, centralized collection, or disposal.

[0100] The solution of this application is implemented in the following way: In the X-ray detection production line for bone samples in a slaughterhouse, when the X-ray detection module and the image processing and intelligent recognition module detect foreign objects in meat products and determine them as defective products, the diversion mechanism is activated to divert these defective products from the discharge conveyor belt to the first diversion conveyor belt. To effectively handle these defective products, this application further provides a discharge port on the right vertical plate of the U-shaped support, and the discharge port of the first diversion conveyor belt passes through this discharge port. In this way, the defective products collected by the first diversion conveyor belt can be discharged from the U-shaped support through this discharge port. At the same time, a circulating conveyor belt corresponding to the discharge port of the first diversion conveyor belt is provided on the right side of the U-shaped support frame. This circulating conveyor belt can promptly receive the defective products discharged from the first diversion conveyor belt and transport them to the next preset processing stage, such as re-entering the cleaning process, centralized collection area, or waste treatment area. In this way, defective products can be continuously and automatically removed from the sorting mechanism, avoiding accumulation on the first sorting conveyor belt, thus ensuring the smooth operation of the sorting mechanism and the continuous production efficiency of the entire production line. This solution automates the handling of defective products, reduces the need for manual intervention, and improves the overall intelligence level of the production line.

[0101] The following is a concrete example: A rectangular discharge port measuring 20cm x 10cm can be opened on the right vertical plate of the U-shaped support, with its lower edge flush with the conveying surface of the first diversion conveyor belt. The end of the first diversion conveyor belt can be designed as a cantilever structure, with its discharge port extending approximately 5cm beyond the U-shaped support to ensure that defective products can slide out smoothly. To the right of the U-shaped support frame, a small belt-type circulating conveyor can be installed, with its receiving end precisely aligned with the discharge port of the first diversion conveyor belt and slightly lower than its discharge height, forming a smooth transition. This circulating conveyor belt can be equipped with a variable frequency speed-regulating motor to adjust the conveying speed according to the discharge speed of defective products, ensuring efficient receiving and transfer. For example, this circulating conveyor belt can transport defective products to a temporary storage box, or send them back to the pre-cleaning section via another conveyor belt for secondary cleaning and inspection.

[0102] Through the above technical solution, the X-ray bone detection production line in slaughterhouses can achieve automated and continuous processing of defective products. The discharge port located on the right vertical plate of the U-shaped support base, and the discharge port of the first diversion conveyor belt passing through this port, ensure that defective products are discharged promptly. Simultaneously, the circulating conveyor belt corresponding to the discharge port of the first diversion conveyor belt further ensures that defective products are efficiently transferred to subsequent processing stages, avoiding accumulation of defective products inside the diversion mechanism and effectively solving the problems of tedious and inefficient manual cleaning. This not only improves the automation level and production efficiency of the entire production line but also ensures the continuity and stability of the production process and reduces operating costs.

[0103] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
