Description

Technical Field

[0001] This application relates to the field of hot pressing technology, and in particular to a hot pressing control method, apparatus, equipment and storage medium for nameplate printing. Background Technology

[0002] Thermoforming is a simple and common processing method in the plastics processing industry. It can be used to heat-press plastic materials such as PVC, PET, PC and PE. Thermoforming can improve the efficiency of plastic molding, make the thickness of the finished product uniform, and reduce processing costs.

[0003] Currently, when hot-pressing nameplates made of plastic materials such as PVC, PET, PC, and PE using thermoforming technology, it is necessary to strictly control the heating temperature and hot-pressing time of the heater to avoid the formation of plastic memory stress within the nameplate during molding, which would prevent the production of an ideal nameplate product. However, currently, when hot-pressing nameplates, it is common to use a heating mold at the same temperature for a preset time, and after hot pressing, the heating mold is opened to allow the nameplate to cool and solidify. During the solidification process, the lack of pressure at the deformed areas can cause slight shape rebound, resulting in defective products and increasing the defect rate of hot-pressed nameplates. Summary of the Invention

[0004] The main objective of this application is to provide a hot pressing control method, apparatus, equipment, and storage medium for nameplate printing, aiming to solve the technical problem in the prior art where, during the nameplate cooling and shaping process, a lack of pressure at the deformed area results in slight shape rebound, causing the product to become defective and leading to an increased defect rate in nameplate hot pressing.

[0005] To achieve the above objectives, this application provides a hot-pressing control method for nameplate printing, the hot-pressing control method for nameplate printing comprising:

[0006] Detect the temperature of the heating mold itself;

[0007] When the temperature of the heating mold reaches the preset maximum temperature, heating is stopped so that the residual heat of the heating mold can be used to complete the hot pressing of the nameplate.

[0008] The highest temperature is the highest temperature of the residual heat when the residual heat of the heating mold is used to complete the remaining hot pressing work.

[0009] Optionally, before the step of stopping heating the heating mold when the self-temperature is detected to have reached a preset maximum temperature, the method further includes:

[0010] Obtain the historical hot-pressing data of the nameplate;

[0011] From the historical hot pressing data, the cooling rate of the heating mold and the rate of change of the mechanical properties of the nameplate at different temperatures are analyzed.

[0012] Based on the rate of change, the cooling rate, and the preset critical temperature, calculate the highest temperature at which the heating mold needs to stop heating;

[0013] The critical temperature is the minimum temperature required for the hot pressing deformation of the nameplate.

[0014] Optionally, the step of resolving the rate of change of the mechanical properties of the nameplate at different temperatures from the historical hot-pressing data includes:

[0015] From the historical hot pressing data, the material information of the nameplate, the changes in the mechanical properties of the nameplate at the start of hot pressing, and the temperature changes of the heating mold are extracted.

[0016] Based on the material information, the nameplates are classified;

[0017] Based on the changes in mechanical properties and the changes in temperature, the rate of change of mechanical properties of different types of nameplates at different temperatures is determined.

[0018] Optionally, the step of calculating the highest temperature at which the heating mold needs to be stopped based on the rate of change, the cooling rate, and a preset critical temperature includes:

[0019] Based on the rate of change, the cooling rate, and the preset critical temperature, a residual heat hot pressing simulation was performed on the nameplate to obtain the simulation results.

[0020] Based on the simulation results, the average time required for the nameplate to complete hot pressing based on the residual heat of the heating mold is calculated.

[0021] Based on the average duration, the highest temperature at which the heating mold needs to be stopped is determined.

[0022] Optionally, the step of performing waste heat hot pressing simulation on the nameplate based on the rate of change, the cooling rate, and a preset critical temperature to obtain simulation results includes:

[0023] Based on the rate of change, the time required for the mechanical properties of the nameplate to stabilize before the residual heat of the heating mold reaches the preset critical temperature is determined.

[0024] Based on the rate of change and the cooling rate, the nameplate is hot-pressed using the residual heat of the heating mold to obtain the actual changes in the mechanical properties.

[0025] Based on the actual changes, the simulation results determine the time required for the mechanical properties to stabilize when the residual heat is not lower than the preset critical temperature.

[0026] Optionally, the step of calculating the average time required for the nameplate to complete hot pressing based on the simulation results using the residual heat of the heating mold includes:

[0027] From the simulation results, the cooling temperature of the heating mold when each mechanical property reaches a stable state is selected.

[0028] Determine whether the difference between the cooling temperature and the critical temperature meets the preset minimum temperature range;

[0029] If the minimum temperature is met, then the settling time required for the corresponding mechanical properties to stabilize is obtained;

[0030] Based on the shaping time, calculate the average time required for the nameplate to complete hot pressing using the residual heat of the heating mold.

[0031] Optionally, before the step of stopping heating the heating mold when the self-temperature is detected to have reached a preset maximum temperature, the method further includes:

[0032] Determine the type of the nameplate;

[0033] Based on the type, select the corresponding highest temperature.

[0034] This application also provides a device for controlling the hot pressing of nameplate printing, the device comprising:

[0035] The detection module is used to detect the temperature of the heating mold itself.

[0036] The waste heat hot pressing module is used to stop heating the heating mold when it detects that its own temperature has reached the preset maximum temperature, so as to use the waste heat of the heating mold to complete the hot pressing of the nameplate.

[0037] The highest temperature is the highest temperature of the residual heat when the residual heat of the heating mold is used to complete the remaining hot pressing work.

[0038] This application also provides a device for hot pressing control of nameplate printing. The device for hot pressing control of nameplate printing is a physical node device. The device for hot pressing control of nameplate printing includes: a memory, a processor, and a program for hot pressing control method of nameplate printing stored in the memory and executable on the processor. When the program for hot pressing control method of nameplate printing is executed by the processor, it can implement the steps of the hot pressing control method of nameplate printing as described above.

[0039] This application also provides a storage medium storing a program that implements the hot pressing control method for nameplate printing described above. When the program for the hot pressing control method for nameplate printing is executed by a processor, it implements the steps of the hot pressing control method for nameplate printing described above.

[0040] This application provides a hot pressing control method, apparatus, equipment, and storage medium for nameplate printing. Compared with the prior art, where slight shape rebound occurs at the deformed area due to lack of pressure during the nameplate cooling and shaping process, resulting in defective products and an increased defect rate in nameplate hot pressing, this application detects the temperature of the heating mold itself. When the temperature reaches a preset maximum temperature, heating of the heating mold is stopped to utilize the residual heat of the heating mold to complete the hot pressing of the nameplate. The maximum temperature is the highest temperature of the residual heat when the residual heat of the heating mold is used to complete the remaining hot pressing work. In this application, the temperature of the heating mold is monitored in real time. When the temperature of the heating mold rises to a preset maximum temperature, heating of the heating mold is stopped. The residual heat of the heating mold is used to complete the remaining hot pressing work on the nameplate. This ensures that the heating mold remains hot-pressed on the nameplate and dissipates heat on the nameplate throughout the hot pressing and shaping process. In other words, by using the residual heat of the heating mold to complete the remaining hot pressing work on the nameplate, the heating mold can dissipate heat during operation. It can also reduce the temperature of the nameplate when the heating mold separates from the nameplate, reducing the impact of the temperature of the nameplate after the heating mold leaves the nameplate. This avoids the nameplate's rebound, ensuring that the nameplate meets product requirements, reducing defective products, and lowering the defect rate of the nameplate hot pressing.

[0049] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0050] This application provides a hot-pressing control method for nameplate printing. In the first embodiment of the hot-pressing control method for nameplate printing in this application, refer to... Figure 1 The hot pressing control methods for nameplate printing include:

[0051] Step S10: Detect the temperature of the heating mold itself;

[0052] Step S20: When the self-temperature is detected to have reached the preset maximum temperature, heating of the heating mold is stopped so as to use the residual heat of the heating mold to complete the hot pressing of the nameplate.

[0053] The highest temperature is the highest temperature of the residual heat when the residual heat of the heating mold is used to complete the remaining hot pressing work.

[0054] This embodiment aims to: complete the remaining hot pressing of the nameplate by heating the residual heat of the mold, avoid the nameplate springback, ensure that the nameplate meets product requirements, reduce defective products, and reduce the defect rate of nameplate hot pressing.

[0055] In this embodiment, it should be noted that the hot pressing control method for nameplate printing can be applied to a device for hot pressing control of nameplate printing. This device for hot pressing control of nameplate printing is subordinate to a device for hot pressing control of nameplate printing, and this device for hot pressing control of nameplate printing is part of a system for hot pressing control of nameplate printing.

[0056] In this embodiment, reference Figure 4 The hot pressing control system for nameplate printing includes a pneumatic device, a time controller, a heating control device, a heating mold, and a product positioning device. The heating mold includes a male mold and a female mold. The female mold is fixed at the product positioning device, and the male mold is set on the pneumatic device. The pneumatic device drives the male mold to hot press and position the nameplate on the product positioning device, so that the male mold and the female mold can shape the nameplate.

[0057] In this embodiment, the total time for the heating mold to hot-press the nameplate is controlled by a time controller. The heating time of the heating mold, the heating stop time of the heating mold, and the time for the heating mold to hot-press the nameplate using residual heat can also be recorded.

[0058] In this embodiment, the heating control device can control the heating temperature of the heating mold and keep the temperature of the heating mold within a set range. It can also control the heating rate, heating time, and heating stop time of the heating mold.

[0059] In this embodiment, reference Figure 5 The unpressed nameplate is placed on the product positioning device, and the part of the nameplate to be bent is aligned with the female mold of the heating mold. Then, the male mold of the heating mold is used to press and bend the unpressed nameplate. When the heating mold is heated, the heating control device controls the heating of the heating mold and monitors the temperature of the heating mold in real time. When the temperature of the heating mold rises to the preset maximum temperature, the heating control device controls the heating mold to stop heating, so that the heating mold can use its residual heat to complete the hot pressing of the nameplate. During the hot pressing of the nameplate, the male mold of the heating mold does not separate from the female mold. When the heating control device detects that the temperature of the heating mold drops to the preset critical temperature, or when the time controller detects that the hot pressing time meets the preset time, the hot pressing of the nameplate is stopped.

[0060] In this embodiment, the heating control device monitors the temperature of the heating mold in real time. When the temperature rises to the preset maximum temperature, the heating of the heating mold is stopped, and the residual heat of the heating mold is used to complete the remaining hot pressing work of the nameplate.

[0061] The remaining hot pressing work on the nameplate is completed, thus finalizing the hot pressing and shaping of the nameplate.

[0062] The specific steps are as follows:

[0063] Step S10: Detect the temperature of the heating mold itself;

[0064] The heating mold can be self-heating or it can be equipped with a heating device. The heating mold or heating device is controlled by a heating control device to raise the temperature of the heating mold and monitor the temperature of the heating mold in real time.

[0065] It should be noted that if the heating mold is self-heating, that is, the heating mold is a heating device.

[0066] In this embodiment, if a heating device is provided inside the heating mold, the heating control device can select to maintain the current temperature of the heating mold according to the hot pressing situation of the nameplate. When it is possible to continue heating or cooling, the heating mold will be controlled to heat or cool down to ensure that the mechanical properties of the nameplate are within the preset error range.

[0067] Step S20: When the self-temperature is detected to have reached the preset maximum temperature, heating of the heating mold is stopped so as to use the residual heat of the heating mold to complete the hot pressing of the nameplate.

[0068] The highest temperature is the highest temperature of the residual heat when the residual heat of the heating mold is used to complete the remaining hot pressing work.

[0069] In this embodiment, when the residual heat of the heating mold is used to complete the remaining hot pressing work, the temperature of the heating mold can be detected in real time and the mechanical properties of the nameplate can be inferred. If it is detected that the residual heat cannot complete the remaining hot pressing work on the nameplate, the temperature of the heating mold is maintained at the current temperature. When it is detected that the mechanical properties of the nameplate will stabilize when the temperature drops from the current temperature to the preset critical temperature, the temperature of the heating mold will no longer be controlled, and the heating mold will be allowed to cool down naturally.

[0070] It should be noted that if it is detected that after the residual heat of the heating mold is used to complete the residual hot pressing of the nameplate, the residual heat of the heating mold will still cause changes in the mechanical properties of the nameplate, then a heating control device will be used to help the heating mold cool down so that the residual temperature of the heating mold can drop to within the error range of the critical temperature when the mechanical properties of the nameplate are stable.

[0071] It should be noted that since the mechanical properties of the nameplate are easily affected by temperature, once the mechanical properties are stable, it means that the current temperature of the heating mold will not cause any change in the mechanical properties of the nameplate after hot pressing. In other words, when the temperature of the heating mold drops to a certain temperature, it will no longer affect the mechanical properties of the nameplate after hot pressing, or the effect will be within the preset error range.

[0072] In this embodiment, the nameplate is hot-pressed using the residual heat of the heating mold, which reduces the cooling time of the nameplate in the heating mold, thereby increasing the frequency of hot pressing and improving work efficiency. Furthermore, by controlling the temperature of the heating mold, the nameplate is removed only after it has fully solidified, reducing the defect rate of the hot-pressed nameplate.

[0073] Specifically, before the step of stopping heating the heating mold when the self-temperature is detected to have reached a preset maximum temperature, the method further includes:

[0074] Step A10: Determine the type of the nameplate;

[0075] Step A20: Select the corresponding highest temperature based on the type.

[0076] In this embodiment, since different types of nameplates have different maximum temperatures, it is necessary to determine the type of nameplate before comparing its own temperature with the maximum temperature.

[0077] In this embodiment, the nameplate type can be classified according to the material type and the nameplate size. The nameplates can first be divided into different major categories based on material type, and then nameplates of the same material but different sizes can be divided into subcategories, thereby accurately determining the nameplate type and making the selection of the maximum temperature more precise.

[0078] It should be noted that when classifying nameplates according to different sizes, the size refers to a size range. That is, if the size of a nameplate meets the first size range, then the nameplate belongs to the nameplate type corresponding to the first size range. Since changes in the size of the nameplate will change the overall temperature sensitivity of the nameplate, and the greater the size change, the greater the temperature sensitivity, nameplates of the same material type are classified according to size to reduce the influence of size on the maximum temperature. This ensures that after the heating mold stops heating at the corresponding maximum temperature, all nameplates within the corresponding size range can complete the nameplate shaping using the residual heat of the heating mold within the preset error range. In other words, by improving the accuracy of the influence of the maximum temperature on the nameplate size, the defect rate of nameplate hot pressing is reduced.

[0079] In this embodiment, the residual heat of the heating mold is used to shape the nameplate, which not only makes reasonable use of heat energy, but also reduces the temperature of the nameplate after the heating mold is separated, thereby preventing the user from being burned by the nameplate.

[0080] This application provides a hot pressing control method, apparatus, equipment, and storage medium for nameplate printing. Compared with the prior art, where slight shape rebound occurs at the deformed area due to lack of pressure during the nameplate cooling and shaping process, resulting in defective products and an increased defect rate in nameplate hot pressing, this application detects the temperature of the heating mold itself. When the temperature reaches a preset maximum temperature, heating of the heating mold is stopped to utilize the residual heat of the heating mold to complete the hot pressing of the nameplate. The maximum temperature is the highest temperature of the residual heat when the residual heat of the heating mold is used to complete the remaining hot pressing work. In this application, the temperature of the heating mold is monitored in real time. When the temperature of the heating mold rises to a preset maximum temperature, heating of the heating mold is stopped. The residual heat of the heating mold is used to complete the remaining hot pressing work on the nameplate. This ensures that the heating mold remains hot-pressed on the nameplate and dissipates heat on the nameplate throughout the hot pressing and shaping process. In other words, by using the residual heat of the heating mold to complete the remaining hot pressing work on the nameplate, the heating mold can dissipate heat during operation. It can also reduce the temperature of the nameplate when the heating mold separates from the nameplate, reducing the impact of the temperature of the nameplate after the heating mold leaves the nameplate. This avoids the nameplate's rebound, ensuring that the nameplate meets product requirements, reducing defective products, and lowering the defect rate of the nameplate hot pressing.

[0081] Furthermore, based on the above embodiments of this application, another embodiment of this application is provided, in which reference is made to... Figure 2 Before the step of stopping heating the heating mold when the self-temperature is detected to have reached a preset maximum temperature, the method further includes:

[0082] Step S01: Obtain the historical hot pressing data of the nameplate;

[0083] Step S02: From the historical hot pressing data, analyze the cooling rate of the heating mold and the rate of change of the mechanical properties of the nameplate at different temperatures;

[0084] Step S03: Based on the rate of change, the cooling rate, and the preset critical temperature, calculate the highest temperature at which the heating mold needs to stop heating;

[0085] The critical temperature is the minimum temperature required for the hot pressing deformation of the nameplate.

[0086] In this embodiment, determining the maximum temperature requires utilizing historical hot-pressing data to analyze the impact of different temperatures on the mechanical properties of the nameplate. That is, analyzing the rate of change of the mechanical properties within the nameplate when hot-pressing it at different temperatures, and analyzing the cooling rate of the heating mold from the historical hot-pressing data. Based on the rate of change, the cooling rate, and the preset critical temperature, the maximum temperature at which the heating mold needs to be stopped is calculated.

[0087] In this embodiment, the time required for the mechanical properties of the nameplate to stabilize at any temperature is first determined based on the rate of change. Then, the temperature change value of the heating mold within this time period is determined based on the cooling rate. The highest temperature is calculated based on the critical temperature and the temperature change value.

[0088] It should be noted that determining the maximum temperature by utilizing the changes in the mechanical properties of the nameplate can not only accurately determine the maximum temperature that the heating mold needs to be heated when hot-pressing different types of nameplates, but also prevent the heating mold from being opened before the nameplate is fully shaped and the temperature of the heating mold still affects the mechanical properties of the nameplate. This would cause the master mold to continue heating the nameplate, altering its mechanical properties and resulting in defective products. In other words, by improving the accuracy of the maximum temperature, the success rate of nameplate hot pressing can be increased, thereby reducing the defect rate of nameplate hot pressing.

[0089] Specifically, the step of calculating the highest temperature at which the heating mold needs to be stopped, based on the rate of change, the cooling rate, and a preset critical temperature, includes:

[0090] Step S031: Based on the rate of change, the cooling rate and the preset critical temperature, perform residual heat hot pressing simulation on the nameplate to obtain simulation results;

[0091] Step S032: Based on the simulation results, calculate the average time required for the nameplate to complete hot pressing based on the residual heat of the heating mold;

[0092] Step S033: Based on the average duration, determine the highest temperature at which the heating mold needs to be stopped from heating.

[0093] In this embodiment, since the size of the nameplates in a certain type of nameplate is not the same, but a range of sizes, the maximum temperature that the heating mold needs to be heated during hot pressing of two nameplates with different sizes is different. In order to meet the temperature requirements of all sizes in the same type of nameplate, it is necessary to simulate the residual heat hot pressing of multiple nameplates of the same type, determine the average time required for the residual heat to complete the hot pressing, and determine the cooling temperature value of the heating mold within the average time. Then, based on the cooling temperature value and the critical temperature, the maximum temperature at which the heating mold needs to stop heating is calculated, that is, the average maximum temperature corresponding to this type of nameplate.

[0094] It should be noted that the maximum temperature determined by the average duration can meet the requirements of all nameplates of the same type within a preset error range, thereby increasing the application range of the maximum temperature in the corresponding type without reducing the success rate of nameplate hot pressing.

[0095] In this embodiment, if the heating mold stops heating at its highest temperature and the nameplate is shaped using the residual heat of the heating device, and it is detected that the mechanical properties of the nameplate cannot stabilize before the temperature of the heating mold drops to the critical temperature, the temperature of the heating mold can be maintained at its highest temperature for a certain period of time. When the mechanical properties of the nameplate stabilize, the temperature of the heating mold is within the error range of the critical temperature, thus avoiding the presence of plastic memory stress in the nameplate, which could cause the nameplate to spring back and deform, failing to meet product requirements, and thereby reducing the defect rate of the nameplate.

[0096] Specifically, the step of performing waste heat hot pressing simulation on the nameplate based on the rate of change, the cooling rate, and the preset critical temperature to obtain the simulation results includes:

[0097] Step B10: Based on the rate of change, determine the time required for the mechanical properties of the nameplate to stabilize before the residual heat of the heating mold reaches a preset critical temperature.

[0098] Step B20: Based on the rate of change and the cooling rate, simulate the hot pressing of the nameplate with the residual temperature of the heating mold to obtain the actual change in the mechanical properties;

[0099] Step B30: Based on the actual changes, determine the simulation results of the time required for the mechanical properties to stabilize when the residual heat is not lower than the preset critical temperature.

[0100] It should be noted that since the rate of change of the mechanical properties of the nameplate obtained from historical hot pressing data is the rate of change under constant temperature, the actual change of the mechanical properties of the nameplate under natural cooling of the heated mold is determined through residual heat hot pressing simulation, so as to make the final determined maximum temperature more realistic.

[0101] In this embodiment, each type of nameplate only begins to deform when the temperature of the heating mold reaches a critical temperature, meaning the mechanical properties of the nameplate change significantly. When the temperature of the heating mold exceeds a certain critical temperature, separating the heating mold causes plastic memory stress to form within the nameplate, causing it to recover a certain shape. Consequently, the resulting bent nameplate fails to meet product requirements, resulting in defective products. To ensure that the temperature of the heating mold is precisely controlled within the error range of the critical temperature when the mechanical properties of the nameplate are stable, the simulation results of the mechanical properties of the heating mold undergoing natural cooling at different temperatures are used to accurately determine the simulation results of the time required for the mechanical properties to reach stability under natural cooling at different temperatures. This reduces the number of nameplates that spring back after separation from the heating mold, thereby reducing the defect rate of hot-pressed nameplates.

[0102] In this embodiment, if the temperature of the heating mold has reached the error range of the critical temperature before the mechanical properties of the nameplate are stabilized after simulation, then the simulation data is invalid and the simulation result is not used. That is, the simulation result is not used when determining the average duration.

[0103] Specifically, the step of calculating the average time required for the nameplate to complete hot pressing based on the residual heat of the heating mold, based on the simulation results, includes:

[0104] Step C10: From the simulation results, select the cooling temperature of the heating mold when each mechanical property reaches a stable state;

[0105] Step C20: Determine whether the difference between the cooling temperature and the critical temperature meets the preset minimum temperature range;

[0106] Step C30: If the minimum temperature is met, then obtain the stabilization time required for the corresponding mechanical properties to stabilize.

[0107] Step C40: Based on the shaping time, calculate the average time required for the nameplate to complete hot pressing using the residual heat of the heating mold.

[0108] In this embodiment, after obtaining the simulation results, the difference between the cooling temperature and the critical temperature of the heating mold is calculated, and it is determined whether the difference meets the preset minimum temperature range. If the difference meets the minimum temperature, the molding time required for the corresponding mechanical properties to reach stability under different cooling temperatures is obtained. Finally, the average molding time is calculated to obtain the average time required for the nameplate to complete hot pressing based on the residual heat of the heating mold.

[0109] In this embodiment, if the temperature of the heating mold is outside the error range of the critical temperature when the mechanical properties of the nameplate are stable after simulation, the simulation result is discarded. In other words, the simulation result is not used when determining the average duration.

[0110] In this embodiment, after determining the cooling rate of the heating mold and the rate of change of the mechanical properties of the nameplate at different temperatures, the residual heat hot pressing simulation is used to determine the precise average duration required for the heating mold, in order to improve the accuracy of the nameplate hot pressing and thus reduce the defect rate of the nameplate hot pressing.

[0111] Furthermore, based on the above embodiments of this application, another embodiment of this application is provided. In this embodiment, the step of parsing the rate of change of the mechanical properties of the nameplate at different temperatures from the historical hot-pressing data includes:

[0112] Step S021: From the historical hot pressing data, filter out the material information of the nameplate, the changes in the mechanical properties of the nameplate at the start of hot pressing, and the temperature changes of the heating mold;

[0113] Step S022: Based on the material information, classify the nameplate;

[0114] Step S023: Based on the changes in mechanical properties and the changes in temperature, determine the rate of change of mechanical properties of different types of nameplates at different temperatures.

[0115] The material information can include the material type of the nameplate, the size of the nameplate, etc.

[0116] The dimensions of the nameplate include at least its length, width, and thickness.

[0117] In this embodiment, based on the changes in mechanical properties and temperature, the rate of change of the mechanical properties of the nameplate at different temperatures can be determined, and the trend of the change in mechanical properties with temperature can also be determined, so as to conduct simulation analysis of waste heat hot pressing through this trend.

[0118] In this embodiment, since different types of nameplates have different sensitivities to temperature, that is, the larger the size of the nameplate of the same material, the higher the temperature required for the nameplate to deform and the longer the shaping time, different types of nameplates are analyzed separately when analyzing the rate of change of the mechanical properties of the nameplate to ensure the applicability of the rate of change and avoid using an inapplicable rate of change, which would lead to an increase in the number of defective products.

[0119] Reference Figure 3 , Figure 3 This is a schematic diagram of the device structure of the hardware operating environment involved in the embodiments of this application.
