Description

Technical Field

[0001] The present invention relates to the technical field of packaging quality detection, and in particular to a paste packaging detection system. Background Art

[0002] In numerous industries, including cosmetics, food, and pharmaceuticals, paste products hold a significant position due to their unique texture and user experience. From moisturizing skin creams and nutrient-rich toothpastes to ointments with medicinal properties, paste products are diverse and widely used. Paste packaging is a critical component in protecting the product, maintaining its stable quality, and facilitating consumer use and storage. Its sealing is directly related to product quality and safety. Once packaging seals fail, the paste is susceptible to external environmental factors, such as oxygen, moisture, and bacteria, leading to product deterioration, failure, and even potential health hazards for consumers. Therefore, ensuring the sealing of paste packaging is a crucial prerequisite for protecting product quality and consumer rights, and paste packaging testing technology has emerged and continues to develop.

[0003] Chinese patent announcement number: CN118583774B, discloses an integrated production line for drug patch packaging inspection, including an inspection mechanism, a packaging device is provided on the left side of the inspection mechanism, and a finished product table is fixed on the right side of the inspection mechanism; the inspection mechanism includes a machine tool, a detection pool is fixed at the bottom of the machine tool, and two conveying rollers are rotatably connected to the inner side of the detection pool. The invention controls the height of the slide rail through an electric push rod 1, and based on the height position of the slide rail, the connecting block is raised and lowered accordingly, and the slide is pushed or pulled by the connecting rod 1 to slide along the crossbeam, thereby adjusting the position of the camera, and using the camera to perform appearance inspection on the patch packaging. At the same time, under the action of the sliding connection between the slider 2 and the slide rail, the connecting block and the dividing plate and partition can move along the slide rail. When the slide rail height changes, the partition spacing is adjusted, which can be adapted to the use of patches of different sizes, so that the camera can better inspect the plaster.

[0004] However, the existing technology has the following problems: the existing technology only evaluates the packaging quality through static appearance inspection, and does not consider the impact of dynamic stress in actual transportation on the sealing of the paste packaging. Summary of the Invention

[0005] To this end, the present invention provides a paste packaging detection system to overcome the problem in the prior art that the influence of dynamic stress on the sealing of paste packaging during transportation is not considered, resulting in insufficient accuracy in paste packaging detection.

[0006] To achieve the above objectives, the present invention provides a paste packaging detection system, comprising:

[0007] A conveying module, used for conveying the paste packaging sample to be tested;

[0008] a detection module connected to the transmission module, configured to determine a detection mode according to the viscosity of the paste and to detect the sample to be detected, wherein the detection mode includes a first detection mode and a second detection mode;

[0009] a data analysis module connected to the detection module, configured to determine a fluctuation anomaly characteristic value based on the data of the first detection mode acquired by the detection module, determine the eligibility of the package seal based on the fluctuation anomaly characteristic value, and determine the eligibility of the package seal based on the deformation recovery index determined by the second detection mode;

[0010] A sorting module is connected to the data analysis module and is used to sort unqualified samples according to the judgment results of the data analysis module.

[0011] Furthermore, the detection mode is determined according to the viscosity of the paste, wherein,

[0012] If the paste viscosity is less than the preset viscosity, determining that the detection mode is the first detection mode, the first detection mode is a vibration test;

[0013] If the viscosity of the paste is less than the preset viscosity, the detection mode is determined to be the second detection mode, and the second detection mode is a pressure test.

[0014] Furthermore, the vibration testing process includes:

[0015] Apply periodic mechanical vibration to the sample to be tested by a vibration device;

[0016] Use optical sensors to collect the real-time position fluctuation curve of the packaging sealing film;

[0017] An amplitude parameter and an irregular wave quantity parameter are extracted from the position fluctuation curve.

[0018] Furthermore, the fluctuation anomaly characteristic value is determined by both the amplitude parameter and the irregular wave number parameter.

[0019] Furthermore, the package sealing qualification is determined based on the fluctuation abnormality characteristic value, wherein:

[0020] If the fluctuation abnormality characteristic value is less than the first preset fluctuation abnormality threshold, the packaging seal is determined to be unqualified, and the mechanical vibration amplitude of the vibration device is increased according to the difference between the preset viscosity and the paste viscosity;

[0021] If the fluctuation abnormality characteristic value is greater than or equal to the first preset fluctuation abnormality threshold and less than the second preset fluctuation abnormality threshold, the package sealing is determined to be qualified;

[0022] If the fluctuation abnormality characteristic value is greater than or equal to the second preset fluctuation abnormality threshold, the packaging seal is determined to be unqualified, and the unqualified samples are sorted through the sorting module.

[0023] Furthermore, the pressure test process includes,

[0024] Apply constant pressure to the upper surface of the packaging sealing film through a pressure device and maintain it for a preset time;

[0025] After the pressure is released, the packaging deformation recovery index is obtained through 3D scanning.

[0026] Furthermore, the increase in the mechanical vibration amplitude of the vibration device is negatively correlated with the difference in paste viscosity, wherein the difference in paste viscosity is the difference between the preset viscosity and the paste viscosity.

[0027] Furthermore, the eligibility of the packaging seal is determined based on the deformation recovery index, wherein:

[0028] If the deformation recovery index is less than the preset recovery index, the packaging seal is judged to be unqualified, and the unqualified samples are sorted through the sorting module;

[0029] If the deformation recovery index is greater than or equal to the preset recovery index, the packaging seal is determined to be qualified.

[0030] Furthermore, after adjusting the mechanical vibration amplitude, the sample is re-inspected and the eligibility of the packaging seal is determined again based on the abnormal fluctuation characteristic value, wherein:

[0031] If the fluctuation abnormal characteristic value is less than the preset abnormal characteristic value, the packaging seal is determined to be qualified;

[0032] If the fluctuation abnormal characteristic value is greater than or equal to the preset abnormal characteristic value, the packaging seal is determined to be unqualified, and the preset viscosity is reduced according to the difference between the fluctuation abnormal characteristic value and the preset abnormal characteristic value.

[0033] Furthermore, several adjustment methods are provided for the preset viscosity, and each adjustment method reduces the preset viscosity by a different amount.

[0034] Compared with existing technologies, the present invention offers the advantage of incorporating a dynamic stress detection mechanism. This comprehensive approach, which simulates vibration during transportation through vibration testing and pressure testing to simulate pressure changes during transportation, comprehensively considers the impact of various dynamic stress factors on the sealing performance of paste packaging during transportation. This comprehensive testing method more realistically reflects the sealing performance of the packaging in actual transportation environments, effectively overcoming the shortcomings of existing technologies, improving detection accuracy, and providing a more reliable basis for quality assurance of paste products.

[0035] Furthermore, the present invention automatically determines the detection mode based on the paste viscosity. When the paste viscosity is less than a preset value, the system uses a vibration test mode, applying periodic mechanical vibrations through a vibration device to collect the real-time position fluctuation curve of the packaging sealing film and extract key parameters. When the paste viscosity is greater than or equal to the preset value, the system uses a pressure test mode, applying constant pressure through a pressure device and obtaining the package deformation recovery index. This flexible adjustment of the detection mode based on the paste's characteristics enhances the system's applicability to different types of paste packaging and enables more accurate sealing testing of various paste packaging types.

[0036] Furthermore, the present invention jointly determines the fluctuation anomaly characteristic value by using the amplitude parameter and the irregular wave number parameter, and makes a sealing determination based on the comparison result of the fluctuation anomaly characteristic value with a preset threshold value. During the pressurization test, the sealing qualification of the package is determined directly based on the comparison between the deformation recovery index and the preset recovery index. In addition, the system also has a re-inspection mechanism, which re-inspects the sample after adjusting the mechanical vibration amplitude and re-determines the sealing according to the new fluctuation anomaly characteristic value, further improving the reliability of the determination result. This precise data analysis and determination method effectively avoids misjudgments and missed judgments, and provides strong support for the quality control of paste packaging.

[0037] Furthermore, the present invention can automatically adjust relevant parameters according to the actual situation during the detection process and optimize system performance. In the vibration test, the increase in the mechanical vibration amplitude of the vibration device is negatively correlated with the difference in the viscosity of the paste. The system will automatically adjust the vibration amplitude according to the difference in the viscosity of the paste to ensure the accuracy and effectiveness of the test. At the same time, when the abnormal fluctuation characteristic value exceeds a certain range, the system will reduce the preset viscosity according to the difference, and set up several adjustment methods for the preset viscosity, and each adjustment method has a different reduction in the preset viscosity, so that the system can flexibly respond to different situations and continuously optimize the detection process. This dynamic adjustment mechanism improves the system's adaptability and stability, and further improves the overall performance of the detection system.

[0038] Furthermore, the present invention ensures timely and accurate sorting of unqualified samples after detection, a key step in ensuring production efficiency and quality. The sorting module of the present invention is closely connected to the data analysis module, enabling rapid and accurate sorting of unqualified samples based on the data analysis module's determination results. This prevents unqualified products from flowing into the next process, reducing waste and losses during the production process, while improving the efficiency of the entire production process and ensuring the production quality and progress of the paste product.

[0047] A conveying module, used for conveying the paste packaging sample to be tested;

[0048] a detection module connected to the transmission module, configured to determine a detection mode according to the viscosity of the paste and to detect the sample to be detected, wherein the detection mode includes a first detection mode and a second detection mode;

[0049] a data analysis module connected to the detection module, configured to determine a fluctuation anomaly characteristic value based on the data of the first detection mode acquired by the detection module, determine the eligibility of the package seal based on the fluctuation anomaly characteristic value, and determine the eligibility of the package seal based on the deformation recovery index determined by the second detection mode;

[0050] A sorting module is connected to the data analysis module and is used to sort unqualified samples according to the judgment results of the data analysis module.

[0051] Specifically, the transmission module includes a belt conveyor and a positioning fixture, which are used to stably transport the paste packaging sample to the inspection station and accurately position it; the inspection module includes a vibration device, a pressure device, an optical sensor and a three-dimensional scanner, among which the vibration device is an electromagnetic vibration table, the pressure device is a pneumatic pressure device, and the optical sensor is such as a laser displacement sensor, which is not specifically limited; the data analysis module processes the inspection data through a signal processor and determines the sealing quality, and triggers the corresponding control signal for unqualified cases; the sorting module uses a robotic arm to transfer the package to the corresponding channel according to the judgment result of the data analysis module.

[0052] Specifically, the detection mode is determined according to the viscosity of the paste, wherein, if the viscosity of the paste is less than the preset viscosity, the detection mode is determined to be the first detection mode, and the first detection mode is a vibration test;

[0053] If the viscosity of the paste is less than the preset viscosity, the detection mode is determined to be the second detection mode, and the second detection mode is a pressure test.

[0054] In the embodiment of the present invention, the preset viscosity value is 200 mPa·s, but the value is not limited thereto, and those skilled in the art can adjust the value according to actual needs.

[0055] Specifically, low-viscosity pastes have strong fluidity, and vibration tests can effectively stimulate the sealing film to fluctuate and detect tiny leaks; high-viscosity pastes have poor fluidity, and the damping effect of the paste causes the signal-to-noise ratio of the sealing film fluctuation signal to be too low, so pressure tests are more suitable for evaluating deformation recovery capabilities.

[0056] Specifically, the vibration frequency of the first detection mode is 50 Hz, the initial amplitude is 1 mm, and the detection time is 3 s, but the above values ​​are not limited thereto. Those skilled in the art may adjust the above values ​​according to actual needs.

[0057] Specifically, the vibration testing process includes:

[0058] Apply periodic mechanical vibration to the sample to be tested by a vibration device;

[0059] Use optical sensors to collect the real-time position fluctuation curve of the packaging sealing film;

[0060] An amplitude parameter and an irregular wave quantity parameter are extracted from the position fluctuation curve.

[0061] Specifically, irregular waves refer to waveform characteristics that obviously deviate from the preset normal fluctuation pattern in the real-time position fluctuation curve of the packaging sealing film collected by the optical sensor during the vibration test of the paste packaging sample. For example, sudden amplitude changes, abnormal frequencies, waveform distortions, etc. are all considered irregular waves.

[0062] Specifically, the fluctuation anomaly characteristic value is jointly determined by the amplitude parameter and the irregular wave number parameter, and the fluctuation anomaly characteristic value = the first weight coefficient × the actual average amplitude / amplitude threshold + the second weight coefficient × the irregular wave number parameter / irregular wave threshold, wherein the irregular wave number parameter is calculated by the frequency domain energy ratio method, the first weight coefficient is 0.6, the amplitude threshold is 1.02 mm, the second weight coefficient is 0.4, and the irregular wave threshold is 5%, but the above values ​​are not limited to this, and those skilled in the art can adjust the above values ​​according to actual needs.

[0063] Specifically, the package sealing qualification is determined based on the fluctuation abnormality characteristic value, where:

[0064] If the fluctuation abnormality characteristic value is less than the first preset fluctuation abnormality threshold, the packaging seal is determined to be unqualified, and the mechanical vibration amplitude of the vibration device is increased according to the difference between the preset viscosity and the paste viscosity;

[0065] If the fluctuation abnormality characteristic value is greater than or equal to the first preset fluctuation abnormality threshold and less than the second preset fluctuation abnormality threshold, the package sealing is determined to be qualified;

[0066] If the fluctuation abnormality characteristic value is greater than or equal to the second preset fluctuation abnormality threshold, the packaging seal is determined to be unqualified, and the unqualified samples are sorted through the sorting module.

[0067] In the embodiment of the present invention, the first preset fluctuation abnormality threshold value is 0.85, and the second preset fluctuation abnormality threshold value is 1.25, but the above values ​​are not limited thereto. Those skilled in the art may adjust the above values ​​according to actual needs.

[0068] Specifically, when the fluctuation anomaly characteristic value is less than the first preset fluctuation anomaly threshold, the paste's high viscosity leads to strong intermolecular forces, significantly limiting its fluidity when subjected to external vibrations or pressure. This restricted fluidity significantly reduces the fluctuation amplitude of the paste within the package. By increasing the mechanical vibration amplitude of the vibration device based on the difference between the preset viscosity and the actual paste viscosity, inaccurate test results due to high paste viscosity can be avoided.

[0069] Specifically, the pressure testing process includes:

[0070] Apply constant pressure to the upper surface of the packaging sealing film through a pressure device and maintain it for a preset time;

[0071] After the pressure is released, the packaging deformation recovery index is obtained through 3D scanning.

[0072] Specifically, deformation recovery index = (maximum deformation of the package during pressurization - residual deformation after release of pressure) / maximum deformation of the package during pressurization.

[0073] Specifically, pressure testing can simulate real scenarios such as transportation stacking and storage pressure, and quantify the packaging's ability to resist external pressure. If irreversible deformation occurs after pressurization, it indicates that there is a defect in the sealing film.

[0074] In the embodiment of the present invention, the pressure value is 15 kPa and the preset time length is 5 seconds, but the above values ​​are not limited thereto. Those skilled in the art can adjust the above values ​​according to actual needs.

[0075] Specifically, the increase in the mechanical vibration amplitude of the vibration device is negatively correlated with the difference in paste viscosity. If the difference in paste viscosity is less than a first preset viscosity difference, the first amplitude adjustment coefficient of 1.8 is used to increase the mechanical vibration amplitude to a corresponding value.

[0076] If the paste viscosity difference is greater than or equal to the first preset viscosity difference and less than the second preset viscosity difference, the mechanical vibration amplitude is increased to a corresponding value using a second amplitude adjustment coefficient of 1.5;

[0077] If the paste viscosity difference is greater than or equal to the second preset viscosity difference, the mechanical vibration amplitude is increased to the corresponding value using the third amplitude adjustment coefficient of 1.2;

[0078] The paste viscosity difference is the difference between the preset viscosity and the paste viscosity.

[0079] In the embodiment of the present invention, the first preset viscosity difference is 20 mPa·s, and the second preset viscosity difference is 50 mPa·s, but the above values ​​are not limited thereto, and those skilled in the art may adjust the above values ​​according to actual needs.

[0080] Specifically, the eligibility of the packaging seal is determined based on the deformation recovery index, where:

[0081] If the deformation recovery index is less than the preset recovery index, the packaging seal is judged to be unqualified, and the unqualified samples are sorted through the sorting module;

[0082] If the deformation recovery index is greater than or equal to the preset recovery index, the packaging seal is determined to be qualified.

[0083] In the embodiment of the present invention, the preset recovery index value is 0.9, but the value is not limited thereto, and those skilled in the art can adjust the value according to actual needs.

[0084] Specifically, after adjusting the mechanical vibration amplitude, the sample is re-inspected and the qualification of the packaging seal is re-determined based on the abnormal fluctuation characteristic value.

[0085] If the fluctuation abnormal characteristic value is less than the preset abnormal characteristic value, the packaging seal is determined to be qualified;

[0086] If the fluctuation abnormal characteristic value is greater than or equal to the preset abnormal characteristic value, the packaging seal is determined to be unqualified, and the preset viscosity is reduced according to the difference between the fluctuation abnormal characteristic value and the preset abnormal characteristic value.

[0087] In the embodiment of the present invention, the preset abnormal characteristic value is 1.2, but the value is not limited thereto, and those skilled in the art may adjust the value according to actual needs.

[0088] Specifically, several adjustment methods are set for the preset viscosity, and each adjustment method reduces the preset viscosity by a different amount. If the fluctuation abnormality difference is less than the first preset fluctuation abnormality difference, the first viscosity adjustment coefficient of 0.98 is used to reduce the preset viscosity to the corresponding value.

[0089] If the abnormal fluctuation difference is greater than or equal to the first preset abnormal fluctuation difference and less than the second preset abnormal fluctuation difference, the preset viscosity is reduced to a corresponding value using the second viscosity adjustment coefficient of 0.95;

[0090] If the abnormal fluctuation difference is greater than or equal to the second preset abnormal fluctuation difference, the preset viscosity is reduced to a corresponding value using a third viscosity adjustment coefficient of 0.92;

[0091] The fluctuation abnormality difference is the difference between the fluctuation abnormality characteristic value and the preset abnormality characteristic value.

[0092] In the embodiment of the present invention, the first preset fluctuation abnormality difference value is 0.05, and the second preset fluctuation abnormality difference value is 0.12, but the above values ​​are not limited thereto. Those skilled in the art may adjust the above values ​​according to actual needs.

[0093] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.

[0094] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations.
