[0002] As a modern automated equipment, the pressure control system of the fully automatic shelling machine plays a vital role in ensuring product quality and production efficiency. The fully automatic shelling machine ensures a smooth shell processing process and that the final product meets the predetermined quality requirements by precisely controlling the pressure. The key to pressure control is to ensure the pressure accuracy of each process through precise pneumatic or hydraulic system adjustment to prevent excessive or insufficient pressure from having adverse effects on the material. Specifically, the pressure control of the fully automatic shelling machine is mainly reflected in several aspects: angle pressing, edge pressing, and pressure adjustment during the overall material handling process.

[0003] Then, in the pressure control of the fully automatic shelling machine, the types of materials processed are diverse, including different types of paper, plastics, composite materials, etc. The differences in the characteristics of each material may cause it to react differently during processing.

In addition, environmental factors may cause changes in the flexibility, hardness, etc. of the processed materials.

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] The embodiment of the present application provides a pressure control system and method for a fully automatic shelling machine, the core of which is that the fully automatic shelling machine pressurizes the material according to the initial pressure parameters, starts the pressure monitoring of the working chamber in the fully automatic shelling machine; converts the pressure data obtained by monitoring into the material pressure curve of the working chamber, divides the material pressure curve into stages, obtains the material pressure curve segments of the working chamber at different working pressure stages, and determines the pressure control abnormality of each working pressure stage through the corresponding material pressure curve segments; obtains the material processing data of the fully automatic shelling machine, obtains the parameter rejection degree when the fully automatic shelling machine pressurizes the material according to the initial pressure parameters based on the material processing data, determines the pressure control adjustment amount of each working pressure stage according to the parameter rejection degree and the corresponding pressure control abnormality; regulates the pressure applied at each working pressure stage in the fully automatic shelling machine according to the corresponding pressure control adjustment amount. The above scheme can be used to accurately and dynamically control the applied pressure during the material processing process of the fully automatic shelling machine, so as to improve the yield rate of the material processed by the fully automatic shelling machine.

[0042] Embodiment 1

[0043] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. Figure 1 As shown, this figure is an exemplary flow chart of a pressure control method of a fully automatic shelling machine according to this embodiment of the present application, and the control method includes the following steps:

[0044] In step S1, the fully automatic casing machine applies pressure to the material according to the initial pressure parameters, and starts the pressure monitoring of the working chamber in the fully automatic casing machine.

[0045] In specific implementation, the initial pressure parameters are set according to the type of material processed by the fully automatic shelling machine; the fully automatic shelling machine sets the initial pressure parameters for different material types and processing requirements, and the initial pressure parameters provide a reference value for subsequent pressure monitoring and adjustment, and the fully automatic shelling machine presses the material according to the initial pressure parameters; it should be noted that the initial pressure parameters are usually preset by the operator or the control system, and the initial pressure parameters include the pressure time and the pressure applied in each working pressure stage. In this application, the working pressure stages include the material angle pressing stage, the material edge pressing stage and the material fine pressing stage.

[0046] In addition, in the specific implementation, the pressure monitoring of the working chamber in the fully automatic shelling machine is started by monitoring the pressure of the working chamber in the fully automatic shelling machine through a pressure sensor; the pressure sensor plays a vital role in monitoring the pressure of the working chamber. It can collect the pressure data in the working chamber in real time and feed back these data to the pressure control system to ensure that the applied pressure meets the preset parameter range. Once the pressure sensor is started, the pressure in the working chamber will be continuously monitored, and the pressure data collected by the pressure sensor in real time will be transmitted to the control system.

[0047] In step S2, the pressure data obtained by monitoring is converted into a material pressure curve of the working chamber, and the material pressure curve is divided into stages to obtain material pressure curve segments of the working chamber in different working pressure stages, and the pressure control abnormality of each working pressure stage is determined through the corresponding material pressure curve segments.

[0048] In specific implementation, converting the monitored pressure data into the material pressure curve of the working chamber is to perform polynomial fitting on the monitored pressure data, and then obtain the material pressure curve of the working chamber; first, the pressure data is collected in real time by a pressure sensor installed in the working chamber. The pressure data includes the pressure value at each moment and the corresponding timestamp. The collected pressure data can be preprocessed to remove obvious outliers or noise interference; then, according to the changing trend of the pressure data, an appropriate polynomial order is selected for fitting. In this application, a second-order polynomial is selected. The second-order polynomial is suitable for describing slow and steady pressure changes. By selecting a suitable polynomial order, the data can be smoothed and noise can be removed, while maintaining an accurate description of the original pressure change trend; finally, the collected pressure data is fitted into a smooth curve of pressure variation over time using the least squares fitting method, that is, the material pressure curve of the working chamber. The material pressure curve represents the overall trend of the material pressure in the working chamber.

[0049] In specific implementation, the material pressure curve is divided into stages according to a preset time interval; the time interval of each working pressure stage can be obtained in the initial pressure parameters, for example, the material angle pressure stage can be set to 0-2 seconds, the material edge pressure stage to 2-5 seconds, and the material fine pressing stage to 5-7 seconds. There is no limitation here. The setting of the time interval is based on experimental data or historical experience. It is usually necessary to adjust according to the material type, thickness and equipment performance to ensure the best pressure effect in each stage, so that the fitted material pressure curve can be segmented according to the preset time interval. For example, if the total pressure time is 7 seconds, the curve can be divided into three stages of 0-2 seconds, 2-5 seconds and 5-7 seconds, that is, the material pressure curve segments of the working cavity at different working pressure stages are obtained, and the material pressure curve segments reflect the real-time pressure changes applied to the material.

[0050] Preferably, in this embodiment, reference Figure 2 As shown in FIG. 1 , this figure is an exemplary flow chart for determining the pressure control abnormality of each working pressure application stage in an embodiment of the present application. In this embodiment, the pressure control abnormality of each working pressure application stage is determined by the corresponding material pressure curve segment, which can be specifically implemented by the following steps:

[0051] First, in step S21, for each working pressure application stage, a material pressure curve segment of the working pressure application stage is obtained;

[0052] Then, in step S22, the pressure corresponding to the initial pressure parameters in the working pressure stage is obtained;

[0053] Secondly, in step S23, the mathematical expectation of the material pressure curve segment is determined;

[0054] Then, in step S24, the data fluctuation degree of each material pressure data point in the material pressure curve segment is determined based on the mathematical expectation and the pressure applied pressure;

[0055] Finally, in step S25, the pressure control abnormality of the working pressure application stage is determined by all data fluctuations, and then the pressure control abnormality of each working pressure application stage is obtained.

[0056] In specific implementation, first, for each working pressure application stage, the material pressure curve segment of the working pressure application stage and the pressure corresponding to the initial pressure application parameters of the working pressure application stage can be obtained; then, the mathematical expectation of the material pressure curve segment can be determined, and the mathematical expectation represents the average pressure value in the working pressure application stage; further, the data fluctuation degree of each material pressure data point in the material pressure curve segment can be determined based on the mathematical expectation and the pressure application pressure, and the data fluctuation degree represents the fluctuation degree of the current material pressure data point relative to the overall material pressure curve segment, and the data fluctuation degree can be determined according to the following formula:

[0057]

[0058] in, Indicates the material pressure data point The data volatility, represents the total number of material pressure data points in material pressure curve segment k, a represents the pressure corresponding to the initial pressure parameters in the working pressure stage of material pressure curve segment k, represents the i-th material pressure data point in the material pressure curve segment k, Indicates the jth material pressure data point in material pressure curve segment k, It represents the mathematical expectation of the material pressure curve segment k. The data fluctuation of each material pressure data point in the material pressure curve segment can be obtained by the above method. It should be noted that in each working pressure stage, the mathematical expectation value and data fluctuation are used to judge the stability and accuracy of the pressure, so that the pressure control system can control the pressure parameters at a more detailed level, and help to achieve precise control of the pressure in the pressure process of each working pressure stage, thereby reducing the excessive or insufficient pressure on the material; finally, the pressure control abnormality of the working pressure stage is determined by all the data fluctuations, that is, the standard deviation of all the data fluctuations is used as the pressure control abnormality of the working pressure stage. The pressure control abnormality indicates the abnormality and instability of the pressure control in the corresponding working pressure stage. The pressure control abnormality of each working pressure stage can be obtained by the above method.

[0059] It should be noted that by converting the monitored pressure data into a material pressure curve, the actual pressure changes on the material at each time point can be clearly displayed. The segmented processing of each working pressure stage further refines the control, so that dynamic adjustments can be made according to real-time pressure feedback in each working pressure stage. By calculating the pressure control abnormality, the working pressure stage with large pressure fluctuations can be identified, which helps to identify potential problems and reduce defective products.

[0060] In step S3, the material processing data of the fully automatic shelling machine is obtained, and based on the material processing data, the parameter rejection degree of the fully automatic shelling machine when applying pressure to the material according to the initial pressure parameters is obtained, and the pressure control adjustment amount of each working pressure stage is determined according to the parameter rejection degree and the corresponding pressure control abnormality.

[0061] In this embodiment, a machine vision system is used to obtain material processing data of a fully automatic shelling machine; in specific implementation, first, the high-definition camera in the machine vision system is used to collect all material images processed by the fully automatic shelling machine; then, the material surface feature detection is performed on the material image, so as to determine the deformation, indentation depth and position of the material during the pressing process, and identify whether irregular deformation or excessive indentation occurs during the pressing process, thereby determining whether the material processed by the automatic shelling machine meets the production standards and obtaining the material processing results; finally, the data composed of all material processing results is used as the material processing data of the fully automatic shelling machine, and the material processing data of the fully automatic shelling machine includes the total number of material processing, the total number of good materials and the total number of defective materials.

[0062] It should be noted that the use of a machine vision system to obtain material processing data of a fully automatic casing machine can improve the accuracy, real-time performance and automation level of the production process, especially in terms of precise pressure control, material status monitoring and quality inspection.

[0063] In this embodiment, the parameter rejection degree when the fully automatic casing machine applies pressure to the material according to the initial pressure parameters based on the material processing data can be obtained in the following manner, namely:

[0064] Determine the yield rate when the fully automatic casing machine presses the material according to the initial pressure parameters through the total number of material processing and the total number of good materials in the material processing data;

[0065] According to the yield rate and the expected yield rate, the parameter rejection degree when the fully automatic casing machine presses the material according to the initial pressure parameters is determined.

[0066] In specific implementation, first, the total number of material processing and the total number of good materials in the material processing data can be obtained by traversal, and the ratio of the total number of good materials to the total number of material processing can be used as the yield rate of the fully automatic shelling machine when the material is pressurized according to the initial pressure parameters; then, the expected yield rate can be obtained, and the expected yield rate is predicted based on preset conditions such as material characteristics and historical data; finally, the parameter rejection degree of the fully automatic shelling machine when the material is pressurized according to the initial pressure parameters can be determined according to the yield rate and the expected yield rate, that is, the difference between the yield rate and the expected yield rate is calculated, and the ratio of the difference to the expected yield rate is used as the parameter rejection degree of the fully automatic shelling machine when the material is pressurized according to the initial pressure parameters. The parameter rejection degree indicates the incompatibility of the fully automatic shelling machine when it presses the material according to the initial pressure parameters. The parameter rejection degree can be used to evaluate whether the current pressure parameters need to be adjusted to optimize the material processing process and ultimately improve product quality and pass rate.

[0067] Preferably, in this embodiment, reference Figure 3 As shown, this figure is an exemplary flow chart for determining the pressure control adjustment amount of each working pressure application stage in an embodiment of the present application. In this embodiment, the pressure control adjustment amount of each working pressure application stage is determined according to the parameter rejection degree and the corresponding pressure control abnormality degree, which can be specifically implemented by the following steps:

[0068] First, in step S31, for each working pressure application stage, the pressure application pressure corresponding to the working pressure application stage in the initial pressure application parameters is obtained;

[0069] Then, in step S32, the pressure control adjustment amount of the working pressurizing stage is determined based on the pressurizing pressure, the parameter rejection degree and the pressure control abnormality degree of the working pressurizing stage, so as to obtain the pressure control adjustment amount of each working pressurizing stage.

[0070] In the specific implementation, first, for each working pressure application stage, the pressure corresponding to the working pressure application stage in the initial pressure application parameters can be obtained by traversal; then, the pressure control adjustment amount of the working pressure application stage can be determined based on the pressure application pressure, parameter exclusion degree and pressure control abnormality of the working pressure application stage, that is, the product of the parameter exclusion degree and the pressure application pressure is calculated, and the product of the pressure control abnormality and the pressure application pressure is calculated, and the average value of the two calculation results is used as the pressure control adjustment amount of the working pressure application stage. The pressure control adjustment amount represents the adjustment change of the pressure application pressure of the corresponding working pressure application stage. The pressure control adjustment amount of each working pressure application stage can be obtained in the above manner.

[0071] It should be noted that by acquiring material processing data and calculating parameter rejection, the deviation between the initial pressure applied and the actual effect can be clearly identified. In addition, determining the pressure control adjustment amount for each working pressure stage based on parameter rejection and pressure control abnormality can help quantify the adjustment degree of the pressure control system and help improve pressure control accuracy.

[0072] In step S4, the applied pressure in each working pressure application stage of the fully automatic case making machine is regulated according to the corresponding pressure control adjustment amount.

[0073] In this embodiment, the pressure applied in each working pressure application stage of the fully automatic case making machine is regulated according to the corresponding pressure control adjustment amount in the following manner, namely:

[0074] For each working pressure stage in the fully automatic case making machine, the final pressure of the working pressure stage is determined according to the pressure corresponding to the initial pressure parameters of the working pressure stage and the pressure control adjustment amount of the working pressure stage, thereby completing the regulation of the pressure of each working pressure stage in the fully automatic case making machine.

[0075] In specific implementation, for each working pressure application stage in the fully automatic shell machine, the final applied pressure of the working pressure application stage can be determined according to the pressure application pressure corresponding to the initial pressure application parameters in the working pressure application stage and the pressure control adjustment amount of the working pressure application stage; wherein, when the defective material processed by the fully automatic shell machine is caused by the initial applied pressure being too small, the sum of the pressure application pressure corresponding to the initial pressure application parameters in the working pressure application stage and the pressure control adjustment amount of the working pressure application stage can be used as the final applied pressure of the working pressure application stage; when the defective material processed by the fully automatic shell machine is caused by the initial applied pressure being too large, the difference between the pressure application pressure corresponding to the initial pressure application parameters in the working pressure application stage and the pressure control adjustment amount of the working pressure application stage can be used as the final applied pressure of the working pressure application stage, and the calculated final applied pressure can be input into the fully automatic shell machine in real time through the pressure control system to adjust the working state of the pressure device, and the regulation of the applied pressure of each working pressure application stage in the fully automatic shell machine can be completed in the above manner.

[0076] It should be noted that through the pressure control method based on the pressure control adjustment amount, the fully automatic shelling machine can apply the most suitable pressure in each working pressure stage. This refined control ensures the consistency of material processing in different working stages, avoids overpressure or underpressure, improves the overall processing quality of the material, and reduces the production of defective products.

[0077] It can be seen that in the present application, the applied pressure can be accurately and dynamically controlled during the material processing process of the fully automatic shelling machine; wherein, by converting the monitored pressure data into a material pressure curve, the actual pressure changes of the material at each time point can be clearly displayed, and the segmented processing of each working pressure stage further refines the control, so that dynamic adjustments can be made according to real-time pressure feedback in each working pressure stage, and by calculating the pressure control abnormality, the working pressure stage with large pressure fluctuations can be identified to help identify potential problems; then, by obtaining material processing data and calculating the parameter rejection, the deviation between the applied initial pressure and the actual effect can be clearly identified, and the pressure control adjustment amount for each working pressure stage is determined based on the parameter rejection and the pressure control abnormality, which can help quantify the adjustment degree of the pressure control system and help improve the pressure control accuracy; finally, through the pressure control method based on the pressure control adjustment amount, the fully automatic shelling machine can apply the most suitable pressure in each working pressure stage, and the refined control improves the overall processing quality of the material and reduces the production of defective products.

[0078] In summary, the technical solution adopted in the present application can accurately and dynamically control the applied pressure during the material processing process of the fully automatic shelling machine, so as to improve the yield rate of the material processed by the fully automatic shelling machine.
