The terms used herein are only for the purpose of describing the embodiments of the present application.

[0014] An embodiment of the present application provides a method for detecting the comprehensive protection performance of a packaging bottle, as Figure 1 shown, the method includes: Collect data on the packaging bottle by an image acquisition module to obtain bottle body structure information, where the bottle body structure information includes bottle body geometric structure information and packaging structure information.

[0015] In one embodiment, the system terminal uses the image acquisition module to collect data on the packaging bottle to comprehensively obtain the structure information of the packaging bottle, including the geometric structure information and packaging structure information of the packaging bottle. Among them, the bottle body geometric structure information refers to the physical characteristics such as the shape, size, and volume of the packaging bottle. Through the image acquisition module, geometric parameters such as the contour, height, diameter, bottle mouth shape, and the curve of the bottle body of the packaging bottle can be accurately captured. The packaging structure information refers to factors such as the sealing performance of the packaging bottle, the cap design, the label pasting position and method, etc. The image acquisition module will collect the thread structure of the cap, the integrity of the gasket, the flatness and accuracy of the label, etc., to ensure that the packaging bottle can effectively prevent problems such as contamination, leakage, or label peeling during transportation and storage, thereby ensuring the safety and effectiveness of the packaging bottle.

[0016] Determine the bottle body joint position and the packaging joint position according to the bottle body structure information.

[0017] In one embodiment, the system terminal performs a contour line analysis on the bottle body geometric structure information in the bottle body structure information to identify the geometric features of parts such as the bottle body, bottleneck, and bottle mouth. Then, by extracting parameters such as the dimensions and angles of each part, a geometric model of the packaging bottle is constructed in combination with a CAD modeling component. Subsequently, according to the geometric model of the packaging bottle, the joint positions between the parts of the bottle body are determined, that is, the bottle body joint position. The bottle body joint position refers to the place where the shapes of the parts of the packaging bottle body change significantly, such as the connection between the bottle body and the bottleneck, the transition area between the bottleneck and the bottle mouth, etc. These positions are often key nodes in the structure of the packaging bottle, and their stability and sealing performance are crucial for protecting the contained items. The system terminal analyzes the bonding area between the cap and the bottle mouth for the packaging structure information in the bottle body structure information to understand its shape, size, thread structure, etc. features, and identify the specific form of the packaging joint position, such as the starting point of the cap thread, the position of the gasket, etc. Subsequently, in combination with the results of the packaging feature recognition, the joint position between the cap and the bottle mouth is accurately located, that is, the packaging joint position. The packaging joint position refers to the bonding area between the cap and the bottle mouth of the packaging bottle. This is the first line of defense against contamination and leakage of the contained items, so its sealing performance and firmness are particularly important.

[0018] Input the bottle body joint position and the packaging joint position into a performance detection device to determine the clamping position.

[0019] In one embodiment, in the comprehensive protection performance detection process of the packaging bottle, after determining the bottle body joint position and the packaging joint position, the system terminal inputs this position information into the performance detection device. Inside the performance detection device, in order to be able to perform a stable and effective test on the packaging bottle, the system terminal performs edge expansion on the bottle body joint position and the packaging joint position, and performs clamping avoidance according to the expanded bottle body joint position and packaging joint position, and determines which positions can be used to clamp the packaging bottle to ensure that the packaging bottle will not move or deform during the test, thus affecting the accuracy of the test results.

[0020] Further, the present application provides a method of inputting the bottle body joint position and the packaging joint position into the performance detection device to determine the clamping position, and the method includes: Performing edge expansion according to the bottle body joint position and the packaging joint position, and outputting the expanded bottle body joint position and the expanded packaging joint position; determining a clampable area, where the clampable area does not include the expanded bottle body joint position and the expanded packaging joint position; identifying in the clampable area according to the clamping structure of the clamping component to determine the clamping position.

[0021] Preferably, the system terminal performs edge expansion on the bottle body joint position and the packaging joint position according to a preset expansion range, that is, expands the current bottle body joint position and the packaging joint position outward to form corresponding buffer zones. The preset expansion range is determined according to the material, size, shape of the packaging bottle, and the expected clamping force. For example, a 0.5 cm area is expanded with the bottle body joint position or the packaging joint position as the center. The purpose of this expansion is to avoid direct interference or damage to the key joint positions during the clamping or detection process, and at the same time ensure the stability and accuracy of the detection. Through edge expansion, a safe area can be delimited, and the operation range of the clamping device can be clarified, so as to better protect the integrity of the bottle body joint position and the packaging joint position and ensure the reliability of the detection results. These buffer zones can ensure that the clamping operation does not directly contact these joint positions, thus avoiding possible damage. Subsequently, the system terminal combines these buffer zones with the corresponding bottle body joint position and the packaging joint position to form the expanded bottle body joint position and the packaging joint position. The expanded bottle body joint position and the packaging joint position represent the areas that need to be avoided during clamping. After that, the system terminal excludes the expanded bottle body joint position and the packaging joint position on the entire surface of the bottle body, and uses the remaining part as the clampable area to ensure that the clamping operation will only be performed in the area that has no impact or the least impact on the packaging bottle structure. Then, according to the clamping structure of the clamping component, identification is performed within the determined clampable area to determine the clamping position that meets the preset detection stability. This step is to ensure the stability and accuracy of the clamping operation and avoid unnecessary pressure or damage to the packaging bottle.

[0022] Furthermore, the present application provides a method for identifying the detection stability in the clampable area according to the clamping structure of the clamping component, and the method includes: Obtain the clamping structure of the clamping component, where the clamping structure includes a clamping head, a clamping wall, and a clamping seat; perform detection stability identification in the clampable area according to the clamping structure to determine the clamping position, where the clamping position is the position where the detection stability is greater than the preset detection stability.

[0023] Optionally, the system terminal first establishes a connection with the clamping assembly and obtains the clamping structure of the clamping assembly. This clamping structure includes a clamping head, a clamping wall, and a clamping seat. Among them, the clamping head is the part of the clamping assembly that directly clamps the object. The clamping wall is a wall-like structure that plays a role in supporting, surrounding, or restricting the movement of the object during the clamping process. The clamping seat is the part of the clamping assembly used to install and fix the clamping head. Subsequently, the system terminal performs a stability detection within the determined clampable area. This process is to simulate the clamping within the clampable area, collect stress data, strain data, and displacement distribution, and then identify the detection stability of each clamping position based on the collected data, and calculate the detection stability of each clamping position. After that, the detection stability of each clamping position is compared with the preset detection stability, and the clamping positions greater than the preset detection stability are selected to ensure the stability and safety of the clamping process. This preset detection stability is determined based on the safety of the clamping operation and actual requirements.

[0024] Furthermore, the present application provides a method for identifying the detection stability in the clampable area according to the clamping structure, and the method includes: Establish a CAD model of the clamping assembly according to the clamping structure; set the material physical properties of the clamping assembly, and simulate the stress data, strain data, and displacement distribution of the clamping structure under the force condition of clamping the packaging bottle to be detected according to the CAD model; identify the detection stability of each clamping position according to the stress data, strain data, and displacement distribution, and determine the clamping position.

[0025] Optionally, the system terminal creates basic geometric bodies, such as clamping arms, clamping claws, connectors, etc., in the CAD modeling component according to the clamping structure. These basic geometric bodies are constructed through basic operations such as stretching, rotation, and cutting. Subsequently, the created basic geometric bodies are assembled according to the requirements of the clamping structure to form a complete CAD model. Then, according to the detailed information of the clamping structure, detailed features such as threads, chamfers, fillets, holes, etc. are added to the CAD model. These detailed features are essential to ensure the functionality of the clamping component. After that, according to the material properties used in the clamping component, such as density, elastic modulus, yield strength and other physical properties, the physical properties of the CAD model are set in the CAD modeling component. These physical properties will directly affect the accuracy and reliability of subsequent simulation analysis. After the physical properties are set, the system terminal uses the CAD model to simulate the stress distribution, strain degree and displacement of each part of the clamping structure under the weight of the packaging bottle and possible external forces, and obtains the stress data, strain data and displacement distribution under the force conditions. Stress data and strain data are crucial for evaluating the strength and durability of the clamping structure. By obtaining these data, we can understand the stress concentration of each part of the clamping structure when it is subjected to force, and whether strain exceeding the yield strength of the material will be generated, so as to determine whether the structure will undergo plastic deformation or damage. Displacement distribution is used to evaluate the displacement of the clamping head or other key components under stress conditions, and is an important data for testing the stability of the clamping. Excessive displacement will lead to unstable clamping, affect the detection accuracy of the packaging bottle, and even cause the packaging bottle to fall off. After obtaining stress data, strain data and displacement distribution, the system terminal assigns corresponding weights to stress data, strain data and displacement distribution based on historical experience and expert advice, and then uses the maximum-minimum method to normalize stress data, strain data and displacement distribution. For example, for stress data, the difference between the current value and the minimum value of stress data is used to calculate the ratio of the difference between the maximum value of stress data and the minimum value of stress data to obtain the normalized value of the current value. Then, the system terminal performs a weighted summation calculation on the normalized stress data, normalized strain data, and normalized displacement distribution of each clamping position to obtain the stability score of each clamping position, i.e., the detection stability. Finally, the detection stability of each clamping position is compared with the preset detection stability, and the clamping positions with detection stability greater than the preset detection stability are extracted. These extracted clamping positions will constitute the final clamping positions.

[0026] The clamping component of the performance detection device clamps the packaging bottle to be detected according to the clamping position, and after the clamping is stable, the performance detection of the bottle body joint position and the packaging joint position are performed according to the detection component of the performance detection device, and the bottle body joint performance detection data and the packaging joint performance detection data are output based on the detection sensor.

[0027] In one embodiment, under standard conditions, that is, without applying external additional conditions such as pressurization, etc., the system terminal synchronizes the obtained clamping position to the clamping component of the performance detection device. The clamping component clamps the packaging bottle to be detected according to the received clamping position. Once the packaging bottle is stably clamped, the system terminal activates the detection component in the performance detection device, and the detection component will perform performance detection on the bottle body joint position and the sealing joint position of the packaging bottle. During the detection process, the detection sensors inside the performance detection device will capture and output performance detection data regarding the bottle body joint position and the sealing joint position in real time, that is, bottle body joint performance detection data and sealing joint performance detection data. These data reflect the performance indicators of these two positions in terms of structural strength, sealing performance, pressure resistance, etc., and are important bases for evaluating the quality of the packaging bottle.

[0028] Furthermore, the present application provides a method for outputting bottle body joint performance detection data and sealing joint performance detection data, including: Based on the detection sensors, output bottle body joint performance detection data and sealing joint performance detection data. The detection sensors include acoustic emission sensors and infrared thermal imagers; the acoustic emission sensors are used to obtain surface cracks and internal cracks at the bottle body joint position, as well as surface cracks and internal cracks at the sealing joint position, and the infrared thermal imagers are used to obtain the temperature distribution and temperature changes at the bottle body joint position, as well as the temperature distribution and temperature changes at the sealing joint position.

[0029] Preferably, during the performance detection process, the detection sensors can obtain and output key performance data regarding the bottle body joint position and the sealing joint position of the packaging bottle. The detection sensors include acoustic emission sensors and infrared thermal imagers. The acoustic emission sensors are used to detect possible crack problems at the bottle body joint position and the sealing joint position. Whether it is surface cracks or difficult-to-detect internal cracks, the acoustic emission sensors can effectively identify them through their unique detection mechanism. The working principle of the acoustic emission sensors is based on the acoustic emission signals generated by materials when stressed. By analyzing these signals, the defect conditions inside the materials can be inferred. The infrared thermal imagers focus on measuring the temperature distribution and temperature changes at these two key positions. By capturing and displaying the infrared radiation on the surface of the packaging bottle, the infrared thermal imagers can generate high-precision temperature images. These images not only show the temperature distribution of the bottle body joint and the sealing joint positions, but also reveal the laws and trends of temperature changes. This is of great significance for evaluating the sealing performance, thermal stability, and possible thermal stress problems of the packaging bottle.

[0030] Output the surface cracks and internal cracks at the bottle body joint position, the temperature distribution and temperature change at the bottle body joint position as the bottle body joint performance detection data; output the surface cracks and internal cracks at the encapsulation joint position, the temperature distribution and temperature change at the encapsulation joint position as the encapsulation joint performance detection data.

[0031] Preferably, for the bottle body joint position, the system terminal uses acoustic emission sensors to detect possible surface cracks and internal cracks. These cracks may be caused by defects in the manufacturing process, material fatigue, or external impacts, etc., posing a threat to the integrity and safety of the packaging bottle. At the same time, an infrared thermal imager is used to measure the temperature distribution and temperature change at the bottle body joint position. The temperature data can reveal the thermal stability, sealing performance, and possible areas of thermal stress concentration at this position. The system terminal synthesizes the crack detection data and temperature data in the performance detection device to obtain the bottle body joint performance detection data and output it. For the encapsulation joint position, the system terminal performs the same detection to obtain the encapsulation joint performance detection data and output it.

[0032] Conduct a protective evaluation based on the bottle body joint performance detection data and the encapsulation joint performance detection data, and output the protective performance detection result.

[0033] In one embodiment, during the protective evaluation of the packaging bottle, the system terminal activates the compressive testing machine and the sealing performance testing machine of the performance detection device, and uses these two testing machines to detect the packaging bottle to be tested respectively, and uses detection sensors to obtain the bottle body joint performance detection data and the encapsulation joint performance detection data for each test. Subsequently, the system terminal conducts a protective evaluation on the bottle body joint performance detection data and the encapsulation joint performance detection data under standard conditions, under the compressive testing machine, and under the sealing performance testing machine respectively, obtains the corresponding performance detection results, and summarizes these performance detection results to form the protective performance detection result.

[0034] Furthermore, the present application provides an output of the protective performance detection result, including: The compression testing machine and the sealing performance testing machine connected to the performance detection device respectively detect the packaging bottle to be detected, and based on the detection sensors, obtain the compression-bottle body joint performance detection data, the compression-packaging joint performance detection data, the sealing-bottle body joint performance detection data, and the sealing-packaging joint performance detection data; perform a protective evaluation according to the compression-bottle body joint performance detection data and the compression-packaging joint performance detection data, and output the compression-protective performance detection result; perform a protective evaluation according to the sealing-bottle body joint performance detection data and the sealing-packaging joint performance detection data, and output the sealing-protective performance detection result; according to the compression-protective performance detection result and the sealing-protective performance detection result, output the protective performance detection result.

[0035] Preferably, in order to comprehensively evaluate the protection performance of the packaging bottle to be detected, the system terminal activates the compression testing machine and the sealing performance testing machine in the performance detection device. These two testing machines respectively conduct detailed inspections on the compression resistance and sealing performance of the packaging bottle, and focus on detecting the performance of the bottle body joint position and the packaging joint position. In the compression test, the system terminal uses the compression testing machine to apply pressure to the packaging bottle, and obtains the performance data of the bottle body joint position and the packaging joint position under the compressed state through the detection sensor in real time, obtaining the compression-bottle body joint performance detection data and the compression-packaging joint performance detection data. These data reveal the compression resistance of the packaging bottle at the bottle body joint position and the packaging joint position, including whether cracks, deformations or failures occur. Subsequently, the system terminal compares the compression-bottle body joint performance detection data and the compression-packaging joint performance detection data with the sample bottle body joint performance detection data and the sample packaging joint performance detection data, calculates the absolute difference of each data, and calculates the average value of the calculated results to obtain the bottle body joint performance detection difference and the packaging joint performance detection difference. Then, the calculated bottle body joint performance detection difference and the packaging joint performance detection difference are compared with the bottle body joint performance detection difference range and the packaging joint performance detection difference range to evaluate whether the compression resistance of the packaging bottle at the two joint positions meets the requirements, and generate the compression-protection performance detection result. Among them, the sample bottle body joint performance detection data and the sample packaging joint performance detection data are set based on industry standards, product specification requirements and expert suggestions. The bottle body joint performance detection difference range and the packaging joint performance detection difference range are determined based on safety performance standards and actual needs. In the sealing performance test, the system terminal uses the same method as above to evaluate the sealing effect of the packaging bottle using the sealing performance testing machine to obtain the sealing-protection performance detection result. Similarly, the system terminal conducts the same evaluation process on the bottle body joint performance detection data and the packaging joint performance detection data under standard conditions to obtain the standard-protection performance detection result. Then, the system terminal summarizes the compression-protection performance detection result, the sealing-protection performance detection result, and the standard-protection performance detection result to form the final protection performance detection result. This result comprehensively considers the performance of the packaging bottle in three aspects: standard, compression and sealing, providing a comprehensive and objective evaluation of the overall protection performance of the packaging bottle.

[0036] Furthermore, after the method for generating the twist protection performance detection result is provided in this application, the method further includes: Based on the bottle body structure information, determine whether the packaging bottle to be detected is a special twist-lock packaging bottle. If the packaging bottle to be detected is a special twist-lock packaging bottle, obtain multiple twist detection samples, where the special twist-lock packaging bottle is a packaging bottle with deep pressing and twist-locking; according to the multiple twist detection samples, obtain the twist force change index; according to the twist force change index, generate the twist protection performance detection result; add the twist protection performance detection result to the protection performance detection result.

[0037] Preferably, the system terminal determines whether the packaging bottle to be detected is a special twist-lock packaging bottle according to the bottle body structure information, that is, whether it is necessary to deeply press to open the locking device. If it is confirmed that the packaging bottle to be detected is a special twist-lock packaging bottle, the system terminal performs multiple twist detections based on the torsion testing machine of the performance detection device to collect sufficient sample data and obtain multiple twist detection samples. These sample data will be used for subsequent analysis and evaluation. Subsequently, based on the multiple twist detection samples, the system terminal plots these twist detection samples into a twist detection curve graph. The horizontal axis of the curve graph represents time, and the vertical axis is the twist force value. Then, key twist force change indexes are extracted from the twist detection curve graph, including the initial twist force, peak twist force, twist force change rate, etc. Then, the system terminal compares the extracted twist force change indexes with the corresponding twist force change index thresholds to obtain the twist protection performance detection result. These twist force change index thresholds are determined according to safety performance standards and actual requirements. Finally, the system terminal adds the twist protection performance detection result to the protection performance detection result to comprehensively evaluate the overall protection performance of the packaging bottle.

[0038] Further, after the method provides the output of the protection performance detection result, the method further includes: Judge whether the packaging bottle includes a packaging film; if the packaging bottle includes a packaging film, collect the film material information of the packaging film; perform a protection analysis according to the film material information to generate a film protection performance detection result, where the protection analysis includes physical barrier effectiveness, environmental barrier property, and aging rate; add the film protection performance detection result to the protection performance detection result.

[0039] In one embodiment, the appearance of the packaging bottle is collected by an image acquisition module to determine whether its surface is covered with a packaging film. If there is a film, proceed to the next step; if there is no film, skip the detection steps related to the film. If the packaging bottle includes a packaging film, a material analysis device (such as a spectrometer, X-ray analyzer, or chemical analyzer) is used to detect and collect the material composition of the film, obtaining film material information such as the material type, thickness, structure, and physical and chemical properties of the film. Subsequently, a multi-channel detection model is used to perform a protective analysis on the film material information, generating a film protection performance detection result including physical barrier effectiveness, environmental barrier property, and aging rate. Among them, the physical barrier effectiveness can reflect the protective ability of the film against physical damage (such as friction, impact, puncture, etc.); the environmental barrier property can reflect the barrier effect of the film against external factors such as moisture, oxygen, and ultraviolet rays in the environment; the aging rate can reflect the durability and performance degradation of the film during long-term use. After that, the film protection performance detection result is combined with the protection performance results in other aspects such as bottle body joint and packaging joint to form a complete protection performance detection result. This final protection performance detection result can provide a reference basis for the design improvement, quality control, and usage suggestions of the packaging bottle.

[0040] For the multi-channel detection model, it includes a physical barrier detection channel, an environmental barrier detection channel, and an aging detection channel. Each channel is constructed based on a multi-layer perceptron (MLP). Taking the physical barrier detection channel as an example, first, data preparation is carried out. Sample film material characteristic information and sample physical barrier effectiveness (as percentage data) are collected, and then the collected data is preprocessed, including data cleaning and normalization processing, to ensure the quality and consistency of the input data. Subsequently, the multi-layer perceptron (MLP) model structure is designed, determining the number of nodes in the input layer, hidden layer, and output layer. The number of input layer nodes is determined by the number of features. The hidden layer can be designed with 2 - 3 layers, and the number of nodes in each layer is adjusted according to the data complexity. The number of output layer nodes is 1 (for regression tasks). Then, a suitable activation function (such as ReLU) and loss function (such as mean square error MSE) are selected, and the model parameters are initialized. After that, the training set, validation set, and test set are divided. The model is trained using the training set, and the model parameters are optimized through the backpropagation algorithm. At the same time, the model performance is monitored on the validation set to prevent overfitting. After training is completed, the test set is used to evaluate the model performance, and the prediction accuracy of the physical barrier effectiveness is calculated. If the accuracy meets the expected expectation, the current multi-layer perceptron is output as the final physical barrier detection channel. Otherwise, hyperparameters such as the learning rate and the number of training batches are adjusted to further improve the analysis effect of the physical barrier detection channel.

Next, reference will be made toFigure 2 Describe a comprehensive protection performance detection platform for a packaging bottle according to an embodiment of the present invention.

[0042] A comprehensive protection performance detection platform for a packaging bottle according to an embodiment of the present invention is used to solve the technical problems of incomplete detection and low efficiency in the protection performance detection process of the packaging bottle due to the manual detection method and the application of a single sensor in the traditional detection method, and achieve the accurate identification and performance detection of the bottle body joint position and the packaging joint position of the packaging bottle, automatically collect and analyze the detection data, and improve the comprehensiveness, accuracy and efficiency of the detection.
