Description

Technical Field

[0001] This invention relates to the field of packaging quality inspection technology, and in particular to a paste packaging inspection system. Background Technology

[0002] In numerous industries such as cosmetics, food, and pharmaceuticals, ointment products hold a significant position due to their unique texture and user experience. From moisturizing skin creams and nourishing toothpastes to medicinal ointments, ointment products are diverse and widely used. As a crucial element in protecting products, maintaining their quality stability, and facilitating consumer use and storage, the airtightness of ointment packaging directly impacts product quality and safety. If the packaging seal is compromised, the ointment is susceptible to external environmental factors such as oxygen, moisture, and bacteria, leading to product spoilage, ineffectiveness, and potentially even harm to consumer health. Therefore, ensuring the airtightness of ointment packaging is a vital prerequisite for protecting product quality and consumer rights, leading to the development and continuous advancement of ointment packaging testing technologies.

[0003] Chinese Patent Publication No. CN118583774B discloses an integrated production line for the packaging and testing of pharmaceutical plasters. The line includes a testing mechanism with packaging equipment on its left side and a finished product table fixed on its right side. The testing mechanism includes a machine tool with a testing pool fixed at its bottom. Two conveyor rollers are rotatably connected to the inner side of the testing pool. The invention controls the height of the slide rail via an electric actuator, and based on the slide rail height, the connecting block rises and falls accordingly. Under the pushing or pulling action of the connecting rod, the slide frame slides along the crossbeam, thereby adjusting the camera position. The camera performs visual inspection of the plaster packaging. Simultaneously, under the sliding connection of the slider and the slide rail, the connecting block, partitions, and dividers can move along the slide rail. When the slide rail height changes, the spacing between the partitions adjusts, adapting to different sizes of plasters and allowing the camera to better inspect the plasters.

[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 during actual transportation on the sealing of the ointment packaging. Summary of the Invention

[0005] Therefore, the present invention provides a paste packaging inspection system to overcome the problem that the existing technology does not consider the impact of dynamic stress during transportation on the sealing of paste packaging, resulting in insufficient accuracy in paste packaging inspection.

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

[0007] The conveyor module is used to transport the ointment packaging samples to be tested;

[0008] The detection module, which is connected to the transmission module, is used to determine the detection mode based on the viscosity of the paste and to detect the sample to be tested. The detection mode includes a first detection mode and a second detection mode.

[0009] The data analysis module, which is connected to the detection module, is used to determine the fluctuation abnormality characteristic value based on the data of the first detection mode obtained by the detection module, and to determine the packaging seal qualification based on the fluctuation abnormality characteristic value, and to determine the packaging seal qualification based on the deformation recovery index determined by the second detection mode.

[0010] The 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 based on the viscosity of the paste, wherein,

[0012] If the viscosity of the paste is less than the preset viscosity, the detection mode is determined to be the first detection mode, which is vibration test;

[0013] If the viscosity of the paste is greater than or equal to the preset viscosity, the detection mode is determined to be the second detection mode, which is a pressure test.

[0014] Furthermore, the vibration testing process includes:

[0015] The sample to be tested is subjected to periodic mechanical vibration by a vibration device;

[0016] An optical sensor is used to collect the real-time position fluctuation curve of the packaging sealing film;

[0017] Extract the amplitude parameter and the number of irregular waves from the position fluctuation curve.

[0018] Furthermore, the characteristic values ​​of wave anomalies are jointly determined by the amplitude parameter and the number parameter of irregular waves.

[0019] Furthermore, the packaging sealing qualification is determined based on the abnormal fluctuation characteristic values, among which,

[0020] If the abnormal fluctuation characteristic value is less than the first preset abnormal fluctuation threshold, the packaging seal is deemed 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 abnormal fluctuation characteristic value is greater than or equal to the first preset abnormal fluctuation threshold and less than the second preset abnormal fluctuation threshold, then the packaging is deemed to be sealed properly.

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

[0023] Furthermore, the pressure testing process includes,

[0024] A constant pressure is applied to the upper surface of the packaging sealing film by a pressure device and maintained 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 viscosity difference of the paste, wherein the viscosity difference of the paste is the difference between the preset viscosity and the paste viscosity.

[0027] Furthermore, the suitability of the packaging seal is determined based on the deformation recovery index, among which,

[0028] If the deformation recovery index is less than the preset recovery index, the packaging seal is deemed unqualified, and the unqualified samples are sorted by the sorting module.

[0029] If the deformation recovery index is greater than or equal to the preset recovery index, the packaging is deemed to be sealed properly.

[0030] Furthermore, after adjusting the mechanical vibration amplitude, the sample was re-inspected, and the packaging seal was re-evaluated based on the abnormal fluctuation characteristic values.

[0031] If the fluctuation anomaly characteristic value is less than the preset anomaly characteristic value, the packaging is deemed to be sealed properly.

[0032] If the abnormal fluctuation characteristic value is greater than or equal to the preset abnormal characteristic value, the packaging seal is deemed unqualified, and the preset viscosity is reduced based on the difference between the abnormal fluctuation 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 advantages of this invention lie in its introduction of a dynamic stress detection mechanism. Vibration testing simulates vibration during transportation, and pressure testing simulates potential pressure changes during transport, comprehensively considering the impact of various dynamic stress factors on the sealing performance of ointment packaging. This comprehensive testing method more realistically reflects the sealing performance of packaging in actual transportation environments, effectively overcoming the shortcomings of existing technologies, improving testing accuracy, and providing a more reliable basis for quality assurance of ointment products.

[0035] Furthermore, this invention automatically determines the detection mode based on the viscosity of the paste. When the paste viscosity is less than a preset viscosity, a vibration test mode is adopted, in which periodic mechanical vibration is applied by 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 viscosity, a pressure test mode is adopted, in which a pressure device is used to apply constant pressure and obtain the packaging deformation recovery index. This method of flexibly adjusting the detection mode according to the characteristics of the paste enhances the applicability of the system to different types of paste packaging and can more accurately detect the sealing performance of various paste packaging.

[0036] Furthermore, this invention determines the fluctuation anomaly characteristic value by jointly using amplitude parameters and irregular wave quantity parameters, and judges the sealing performance based on the comparison result of the fluctuation anomaly characteristic value with a preset threshold. In the pressure test, the packaging sealing qualification is directly judged based on the comparison of the deformation recovery index with the preset recovery index. In addition, the system also sets up a re-inspection mechanism, which re-inspects the sample after adjusting the mechanical vibration amplitude and judges the sealing performance again based on the new fluctuation anomaly characteristic value, further improving the reliability of the judgment results. This precise data analysis and judgment method effectively avoids misjudgment and omission, and provides strong support for the quality control of ointment packaging.

[0037] Furthermore, this invention can automatically adjust relevant parameters based on the actual situation during the testing process, optimizing system performance. In vibration testing, the increase in the mechanical vibration amplitude of the vibration device is negatively correlated with the viscosity difference of the paste. The system automatically adjusts the vibration amplitude according to the viscosity difference to ensure the accuracy and effectiveness of the test. Simultaneously, when abnormal fluctuation values ​​exceed a certain range, the system reduces the preset viscosity based on the difference. Several adjustment methods are set for the preset viscosity, and each method reduces the preset viscosity by a different amount, allowing the system to flexibly respond to different situations and continuously optimize the testing process. This dynamic adjustment mechanism improves the system's adaptability and stability, further enhancing the overall performance of the testing system.

[0038] Furthermore, the timely and accurate sorting of non-conforming samples after detection is a crucial step in ensuring production efficiency and quality. The sorting module of this invention is closely integrated with the data analysis module, enabling rapid and accurate sorting of non-conforming samples based on the analysis results. This prevents non-conforming products from flowing into the next process, reduces waste and losses during production, improves the efficiency of the entire production process, and ensures the production quality and schedule of the ointment products.

[0043] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0044] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0045] It should be noted that the data in this embodiment are all derived from a comprehensive analysis and evaluation of historical test data and corresponding historical test results from the three months prior to this test. Those skilled in the art will understand that the determination of the above-mentioned parameters for any single item in this invention can be achieved by selecting the value with the highest percentage based on the data distribution as the preset standard parameter, using weighted summation to obtain the value as the preset standard parameter, substituting each historical data point into a specific formula and using the value obtained from that formula as the preset standard parameter, or other selection methods, as long as the invention can clearly define different specific situations in the single-item judgment process through the obtained values.

[0046] Please see Figures 1 to 4 The diagrams shown are: a schematic diagram of the module connection of the paste packaging inspection system; a flowchart of the invention embodiment for determining the inspection mode based on the paste viscosity; a flowchart of the invention embodiment for determining the packaging seal qualification based on the fluctuation abnormality characteristic value; and a flowchart of the invention embodiment for determining the packaging seal qualification based on the deformation recovery index.

[0047] The conveyor module is used to transport the ointment packaging samples to be tested;

[0048] The detection module, which is connected to the transmission module, is used to determine the detection mode based on the viscosity of the paste and to detect the sample to be tested. The detection mode includes a first detection mode and a second detection mode.

[0049] The data analysis module, which is connected to the detection module, is used to determine the fluctuation abnormality characteristic value based on the data of the first detection mode obtained by the detection module, and to determine the packaging seal qualification based on the fluctuation abnormality characteristic value, and to determine the packaging seal qualification based on the deformation recovery index determined by the second detection mode.

[0050] The 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 conveying module includes a belt conveyor and positioning fixtures for stably conveying the ointment packaging samples to the testing station and accurately positioning them; the testing module includes a vibration device, a pressure device, an optical sensor, and a 3D scanner, wherein the vibration device is an electromagnetic vibration table, the pressure device is a pneumatic pressure device, and the optical sensor is, for example, a laser displacement sensor, which is not specifically limited; the data analysis module processes the test data through a signal processor and determines the sealing qualification, triggering corresponding control signals for unqualified cases; the sorting module uses a robotic arm to transfer the packaging to the corresponding channel according to the judgment results of the data analysis module.

[0052] Specifically, the detection mode is determined based on the viscosity of the paste. If the viscosity of the paste is less than the preset viscosity, the detection mode is determined to be the first detection mode, which is vibration test.

[0053] If the viscosity of the paste is greater than or equal to the preset viscosity, the detection mode is determined to be the second detection mode, which is a pressure test.

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

[0055] Specifically, low-viscosity pastes have strong fluidity, and vibration testing can effectively excite the undulation of the sealing membrane to detect minor leaks; high-viscosity pastes have poor fluidity, and due to the damping effect of the paste, the signal-to-noise ratio of the undulation signal of the sealing membrane is too low, making pressure testing more suitable for evaluating deformation recovery ability.

[0056] Specifically, the vibration frequency of the first detection mode is 50Hz, the initial amplitude is 1mm, and the detection duration is 3s. However, the above values ​​are not limited to these, and those skilled in the art can adjust the above values ​​according to actual needs.

[0057] Specifically, the vibration testing process includes:

[0058] The sample to be tested is subjected to periodic mechanical vibration by a vibration device;

[0059] An optical sensor is used to collect the real-time position fluctuation curve of the packaging sealing film;

[0060] Extract the amplitude parameter and the number of irregular waves from the position fluctuation curve.

[0061] Specifically, irregular waves refer to waveform characteristics that deviate significantly from the preset normal fluctuation pattern in the real-time position fluctuation curve of the packaging sealing film collected by optical sensors during vibration testing of ointment packaging samples. For example, phenomena such as sudden amplitude changes, abnormal frequency, and waveform distortion are all considered irregular waves.

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

[0063] Specifically, the packaging sealing qualification is determined based on the abnormal fluctuation characteristic values, among which...

[0064] If the abnormal fluctuation characteristic value is less than the first preset abnormal fluctuation threshold, the packaging seal is deemed 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 abnormal fluctuation characteristic value is greater than or equal to the first preset abnormal fluctuation threshold and less than the second preset abnormal fluctuation threshold, then the packaging is deemed to be sealed properly.

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

[0067] In this embodiment of the invention, the first preset abnormal fluctuation threshold is 0.85 and the second preset abnormal fluctuation threshold is 1.25. However, the above values ​​are not limited to these values, and those skilled in the art can adjust the above values ​​according to actual needs.

[0068] Specifically, when the abnormal fluctuation characteristic value is less than the first preset abnormal fluctuation threshold, the paste has a high viscosity and strong intermolecular forces, which greatly restricts its flowability when subjected to external vibration or pressure. This restricted flowability leads to a significant reduction in the fluctuation amplitude of the paste within the packaging. By increasing the mechanical vibration amplitude of the vibration device according to the difference between the preset viscosity and the actual paste viscosity, the problem of inaccurate test results due to high paste viscosity can be avoided.

[0069] Specifically, the pressure test process includes:

[0070] A constant pressure is applied to the upper surface of the packaging sealing film by a pressure device and maintained for a preset time.

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

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

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

[0074] In this embodiment of the invention, the pressure is 15 kPa and the preset duration is 5 seconds, but the above values ​​are not limited to these. 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 viscosity difference of the paste. If the viscosity difference of the paste is less than the first preset viscosity difference, the mechanical vibration amplitude is increased to the corresponding value using the first amplitude adjustment coefficient of 1.8.

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

[0077] If the viscosity difference of the paste 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 viscosity difference of the paste is the difference between the preset viscosity and the paste viscosity.

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

[0080] Specifically, the quality of packaging sealing is determined based on the deformation recovery index, among which...

[0081] If the deformation recovery index is less than the preset recovery index, the packaging seal is deemed unqualified, and the unqualified samples are sorted by the sorting module.

[0082] If the deformation recovery index is greater than or equal to the preset recovery index, the packaging is deemed to be sealed properly.

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

[0084] Specifically, after adjusting the mechanical vibration amplitude, the sample is re-inspected, and the packaging seal is re-evaluated based on the abnormal fluctuation characteristics.

[0085] If the fluctuation anomaly characteristic value is less than the preset anomaly characteristic value, the packaging is deemed to be sealed properly.

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

[0087] In this embodiment of the invention, the preset abnormal feature value is 1.2, but the value is not limited to this. Those skilled in the art can adjust the value according to actual needs.

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

[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, then the preset viscosity is reduced to the 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 the corresponding value using the third viscosity adjustment coefficient of 0.92.

[0091] The fluctuation anomaly difference is the difference between the fluctuation anomaly feature value and the preset anomaly feature value.

[0092] In this embodiment of the invention, the first preset fluctuation abnormality difference is 0.05 and the second preset fluctuation abnormality difference is 0.12. However, the above values ​​are not limited to these values, and those skilled in the art can adjust the above values ​​according to actual needs.

[0093] The technical solution of the present invention has been described above with reference to 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 can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.

[0094] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
