Description

Technical Field

[0001] This application relates to the technical field of sheet metal processing, and in particular to a sheet metal pressing control method, electronic equipment, storage medium, and sheet metal pressing device. Background Technology

[0002] Sheet lamination is an industrial process used to bond films, paper, or other decorative materials to the surface of sheet materials under pressure to improve their appearance, protective properties, or functionality. It is commonly used in furniture, architectural decoration, and electronics manufacturing. The process typically involves placing the sheet material in a laminating machine, aligning it with the laminating material, and then applying pressure through upper and lower laminating plates to ensure uniform adhesion. In double-sided lamination applications, both sides of the sheet material are laminated simultaneously, sometimes using different textures or materials for the two sides to meet diverse design requirements.

[0003] During double-sided lamination, when films with different textures or materials need to be laminated on both sides of a board, the required lamination conditions often differ due to the variations in the physical properties of the materials. Using uniform lamination parameters may result in excessive pressure and prolonged lamination time, causing board deformation or indentation, or insufficient pressure, leading to blistering or peeling of the lamination, thus reducing product yield. The underlying principle is that stress distribution during lamination is affected by material differences; the mismatch in deformation behavior of different laminations prevents uniform stress distribution at the lamination interface, affecting the tightness of the bond.

[0004] To address the aforementioned issues, existing technologies typically process the two sides separately. First, one side is laid down and pressed, and then the other side is laid down and pressed. This approach has several drawbacks. First, pressing in stages increases the pressing cost. Second, the second pressing can affect the side that was pressed in the first stage.

[0005] Therefore, improving the pressing quality of double-sided lamination of sheet metal is a technical problem that urgently needs to be solved. Summary of the Invention

First, lamination parameters of the sheet metal are obtained, including first lamination parameters for the first bonding surface and second lamination parameters for the second bonding surface, providing a data basis for subsequent calculations of lamination conditions. Then, based on these differentiated lamination parameters, a first temperature range and a first pressure range suitable for lamination of the first bonding surface, and a second temperature range and a second pressure range suitable for lamination of the second bonding surface are derived. Next, the intersection of the two pressure ranges is used to determine a safe pressure range, matching the requirement of uniform pressure on both sides of the lamination equipment, ensuring that the pressure value can simultaneously meet the safety requirements of lamination on both sides. Finally, the sheet metal lamination parameters, the two temperature ranges, and the safe pressure range are combined... The first and second pressing time intervals are calculated separately. The intersection of the two time intervals is then taken to obtain the safe pressing time interval, which can be synchronously adapted to the pressing time requirements of both sides. Finally, based on the time value within the safe pressing time interval, the pressure value within the safe pressure interval, and the temperature value within the temperature intervals that are adapted to both sides, the board is pressed synchronously on both sides. The time and pressure values ​​can simultaneously meet the common requirements of both sides, and the temperature values ​​of both sides match the individual requirements of their respective bonding surfaces. This ensures that both sides of the board have suitable pressing temperature, pressure, and time, thereby significantly improving the bonding tightness and yield of the double-sided pressing of the board and effectively improving the pressing quality of the double-sided pressing of the board.

[0024] Therefore, improving the pressing quality of double-sided lamination of sheet metal is a technical problem that urgently needs to be solved.

[0025] To address the aforementioned issues, this embodiment provides a sheet metal lamination method to improve the lamination quality of double-sided sheet metal lamination.

[0026] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0027] See Figure 1 This embodiment provides a method for controlling the pressing of sheet metal, including: S1: Obtain the pressing parameters of the board, including the first pressing parameters of the first bonding surface and the second pressing parameters of the second bonding surface; It should be noted that this step, as the initial stage of the sheet metal lamination control method, provides a crucial data foundation for subsequent calculations by obtaining the sheet metal lamination parameters, thereby solving the lamination quality problem caused by the difference between the two materials in double-sided lamination. Setting this step ensures that the lamination conditions are calculated differently based on actual parameters, avoiding sheet metal deformation or film peeling caused by the same parameters, effectively improving the accuracy and adaptability of the lamination process, and laying a reliable input foundation for the overall solution.

[0028] Specifically, the purpose of obtaining the pressing parameters of the sheet material is to collect key attributes that affect the pressing effect, so as to calculate the temperature, pressure and time range in the future. This can be achieved in various ways, such as detecting the characteristics of the sheet material by sensors or querying parameter values ​​from a preset database before starting the pressing equipment. Application scenarios include automatic parameter identification when the sheet material enters the pressing area in an automated production line. For example, when the sheet material enters the pressing machine via a conveyor belt, the radio frequency identification tag is read to obtain the pre-stored pressing parameters from the server, or the operator inputs the sheet material specifications through a touch screen.

[0029] It is worth noting that the pressing parameters include the first pressing parameters of the first bonding surface and the second pressing parameters of the second bonding surface. This design allows for the separate handling of the different requirements of the two sides, and its function is to achieve precise control by distinguishing the parameters of the two sides. During operation, the parameters of the two sides need to be obtained separately, for example, by scanning the texture of the two sides through a vision system or by using a thickness gauge to measure the thickness of the two sides.

[0030] S2: Calculate the first temperature range and the first pressure range of the first bonding surface based on the first pressing parameters, and calculate the second temperature range and the second pressure range of the second bonding surface based on the second pressing parameters; It should be noted that this step calculates the temperature and pressure ranges of the first and second bonding surfaces based on the sheet metal pressing parameters, thereby determining the double-sided pressing conditions and providing a data basis for subsequent calculations.

[0031] Specifically, the function of the sheet pressing parameters is to drive range calculations using parameter values ​​to ensure that the results are based on the actual sheet characteristics. During operation, calculations can be performed through the parameter processing module, such as inputting parameters into a preset algorithm or querying a mapping table. Application scenarios include real-time processing of parameter data by the pressing equipment control system. For example, pressing parameters such as material and thickness are used to retrieve corresponding ranges in the database, or through calculation formulas such as temperature range equal to base temperature multiplied by material coefficient plus thickness offset.

[0032] Specifically, the purpose of calculating the first temperature range and the first pressure range of the first bonding surface is to determine the safe pressing boundary for the first surface, preventing the temperature or pressure from exceeding the material's tolerance range. During operation, the range values ​​are derived based on the first pressing parameters. For example, for the temperature range, the minimum and maximum temperatures are calculated using the material's thermal expansion coefficient and thickness. For the pressure range, the pressure range is determined based on the surface hardness and texture. This is commonly used in automated pressing lines where the controller executes the calculation logic. For example, the first temperature range can be calculated using a lookup table, such as when the first surface material is PVC and the thickness is 2 mm, a preset table is consulted to obtain a temperature range of 160-180°C. Alternatively, it can be calculated using a model, such as using the thermal conductivity equation to derive a temperature range of 155-175°C based on the material's thermal conductivity. Similarly, the first pressure range calculation can include two cases: one is to calculate the pressure range as 8-12 MPa based on the texture roughness using an empirical formula, and the other is to output a pressure range of 6-10 MPa based on the material hardness using a linear regression model.

[0033] It is worth noting that the calculation process must ensure that the interval values ​​cover the pressing safety threshold. If the parameters are abnormal, such as exceeding the thickness limit, the default interval should be used. Specifically, the purpose of calculating the second temperature interval and the second pressure interval for the second bonding surface is to independently adapt to the requirements of the second surface, ensuring personalized pressing conditions for both surfaces. The operation is similar to that of the first surface, but the parameters of the second surface are used. For example, if the second surface is a metal coating, a higher temperature interval is calculated. In the application scenario, the system processes the parameters of both surfaces in parallel. For example, the second temperature interval may be obtained as 170-190°C through the same table lookup method, or it may be calculated based on environmental factors, but this implementation focuses on basic calculations. Another approach is to calculate directly without considering the ambient temperature, although the accuracy is slightly lower, it can still solve the pressing problem. Through the above calculations, the intervals of the two surfaces lay the foundation for subsequent intersection processing, ensuring accurate and reliable pressing control.

[0034] S3: Take the intersection of the first pressure range and the second pressure range to obtain the safe pressure range; It should be noted that this step obtains the safe pressure range by taking the intersection of the first and second pressure ranges. Because the double-sided lamination of the sheet metal is a reciprocating process, the pressure on both sides must be equal to ensure the sheet remains stationary during lamination. If the pressures on the two sides are different, it will cause one side of the steel plate to push the other side, and the pressures on both sides will affect each other. Therefore, by calculating the safe pressure range, the independently calculated pressure ranges on both sides can be unified into a compatible range, ensuring that the lamination pressure simultaneously meets the safety requirements of both sides of the sheet metal, avoiding sheet deformation or coating blistering problems caused by mismatched pressure values.

[0035] Specifically, the purpose of taking the intersection of the first pressure range and the second pressure range is to identify the common safe range of the pressure requirements on both sides, and to prevent pressure overload or underload. During operation, the intersection can be calculated by comparing the boundary values ​​of the ranges. For example, in the pressing control system, an algorithm is used to compare the minimum and maximum values ​​of the first pressure range with the minimum and maximum values ​​of the second pressure range, and the overlapping part is taken as the intersection. Application scenarios include real-time processing of the calculated pressure range data in automated pressing lines.

[0036] It is worth noting that the sheet metal pressing machine uses two steel plates to press the two sides of the sheet metal in opposite directions. The two steel plates are in contact with the two sides of the sheet metal respectively. Therefore, in actual operation, the two sides of the sheet metal can be heated at different temperatures. However, due to the opposite pressing, the pressing pressure and pressing time on both sides must be consistent.

[0037] Preferably, to improve the accuracy of the safe pressure range, this embodiment provides a preferred solution in which, when taking the intersection of the first pressure range and the second pressure range, a gradient descent algorithm is used to optimize the range boundary. It should be noted that setting this feature allows for dynamic adjustment of the intersection boundary to minimize pressure setting errors and avoid the risk of sheet deformation or film blistering caused by pressure values ​​approaching the range endpoints. This embodiment ensures the robustness of the pressure range intersection through algorithm optimization, directly helping to improve the stability of the pressing process and the product qualification rate.

[0038] Specifically, the purpose of using the gradient descent algorithm to optimize the interval boundaries is to find the optimal intersection boundary through iterative search, maximizing the pressure value within a safe range to meet the needs of both sides and preventing boundary mismatch problems that may be overlooked by simply taking the intersection. During operation, an optimization module can be integrated into the pressure control system. For example, the first and second pressure intervals can be used as inputs, a loss function such as minimizing the pressure variance or maximizing the safety margin can be defined, and then the gradient descent algorithm can be applied to iteratively adjust the boundary values. Application scenarios include real-time processing of the calculated pressure interval data followed by optimization. For example, the gradient descent algorithm can be applied in two ways: one is batch gradient descent, where the loss function is based on the width of the overlapping intervals, and the algorithm calculates the gradient and updates the boundaries until convergence; the other is stochastic gradient descent, which optimizes speed through random sampling for large-scale data or real-time adjustment scenarios, but may have slightly lower accuracy. It is worth noting that if the algorithm does not converge or the intervals do not overlap, the system can enable a backup scheme, such as taking the midpoint of the interval as the default boundary, but this implementation focuses on optimization.

[0039] S4: Calculate the first pressing time interval based on the first pressing parameters, the first temperature range, and the safe pressure range; calculate the second pressing time interval based on the second pressing parameters, the second temperature range, and the safe pressure range; It should be noted that this step calculates the first pressing time interval based on the first pressing parameters, the first temperature range, and the safe pressure range of the sheet material, and calculates the second pressing time interval based on the second pressing parameters, the second temperature range, and the safe pressure range. This achieves coordinated optimization of pressing time with temperature and pressure, thereby solving the problem of poor adhesion or material damage caused by improper time settings in double-sided pressing. This step can convert temperature and pressure parameters into time ranges to ensure that the pressing time is adapted to the personalized needs of both sides.

[0040] Specifically, the purpose of calculating the first pressing time interval based on the board pressing parameters, the first temperature range, and the safe pressure range is to determine the safe pressing time boundary for the first bonding surface, preventing the film from peeling off due to excessively short time or the board from overheating due to excessively long time. During operation, the calculation module can be used to perform the calculation by combining the parameters, temperature range, and pressure range. For example, the parameters can be input into a time prediction algorithm or a multidimensional mapping table can be queried. Application scenarios include the pressing equipment controller processing data in real time and outputting the time range. For example, the calculation of the first pressing time interval can include the following two methods: one is the table lookup method, such as when the board pressing parameters include the material being wood and the thickness being 3 mm, the first temperature range being 160-180°C, and the safe pressure range being 10-12 MPa, the first pressing time interval is obtained by querying the preset database as 120-150 seconds; the other is the formula calculation method, such as using the empirical formula that time equals the base time multiplied by the temperature coefficient and the pressure coefficient, and deriving the interval as 110-140 seconds based on the parameters.

[0041] Similarly, calculating the second pressing time interval based on the sheet metal pressing parameters, the second temperature range, and the safe pressure range serves to independently adapt to the time requirements of the second side, ensuring that the pressing time for both sides is optimized. The operation is similar to the first side but uses specific parameters for the second side; for example, if the second temperature range is higher, a shorter time interval is calculated. In application scenarios, the system processes the calculations for both sides in parallel to improve efficiency. For example, the second pressing time interval can be calculated using the same lookup table method to obtain 130-160 seconds, or using a model method such as a neural network model based on historical data to output the interval. However, this implementation focuses on basic calculations. Another approach is to calculate the time directly without using the safe pressure range, relying only on temperature and parameters. Although the accuracy is lower, it can still partially solve the pressing problem. Through the above calculations, the time intervals for both sides lay the foundation for subsequent intersection processing, ensuring accurate and reliable pressing control.

[0042] S5: Take the first pressing time and the second pressing time, and calculate the safe pressing time range; It should be noted that this step obtains the safe pressing time interval by taking the intersection of the first pressing time interval and the second pressing time interval. This step is crucial to the overall solution because it unifies the time ranges calculated independently on both sides into a compatible interval, ensuring that the pressing time simultaneously meets the safety requirements of both sides of the board and avoiding problems such as film bubbling or board overheating caused by improper time settings. Setting this step can optimize the synchronization of time parameters.

[0043] Specifically, the purpose of taking the intersection of the first and second pressing time intervals is to identify the common safe range of time requirements for both sides, preventing the pressing quality from being affected by excessively short or long times. During operation, the intersection can be calculated by comparing the interval boundary values. For example, in a pressing control system, an algorithm can be used to compare the minimum and maximum values ​​of the first and second pressing time intervals, taking the overlapping portion as the intersection. Application scenarios include real-time processing of calculated time interval data in automated pressing lines. The purpose of obtaining the safe pressing time interval is to provide a reference time parameter for the pressing operation, ensuring that the time is set within the tolerance range of both sides. During operation, the intersection result is stored as the safe pressing time interval value, used to control the timing module of the pressing equipment. In application scenarios, the safe pressing time interval is directly input to the time controller. For example, the safe pressing time interval can be transmitted to the actuator via a data bus. For instance, in one implementation, the system uses the minimum value of the intersection as the starting pressing time; another approach is to use the median value of the interval as the default time. Although the median value may not be optimal, it can still basically meet the pressing requirements, thus supporting the feasibility of the overall solution. Through the above operations, the safe pressing time range provides a reliable basis for subsequent pressing, ensuring that the double-sided pressing is carried out synchronously.

[0044] S6: Select the corresponding time and pressure values ​​from the safe pressing time range and the safe pressure range to press the board on both sides simultaneously. The pressing temperature used on the first bonding surface is within the first temperature range and corresponds to the selected time value. The pressing temperature used on the second bonding surface is within the second temperature range and corresponds to the selected time value.

[0045] It should be noted that this step, as the final execution stage of the sheet metal lamination control method, involves simultaneously laminating both sides of the sheet metal by selecting corresponding time and pressure values ​​from the safe lamination time and pressure ranges. The lamination temperature used on the first bonding surface is within the first temperature range and corresponds to the selected time value, while the lamination temperature used on the second bonding surface is within the second temperature range and corresponds to the selected time value. This achieves synchronous application of lamination parameters, thereby solving the problem of uneven lamination caused by differences in the two-sided materials. Setting this step can convert the previously calculated safe range into actual operation instructions, ensuring that the lamination process is carried out synchronously within the safe range.

[0046] The safe pressing time interval refers to the specific pressing duration that simultaneously meets the pressing requirements of both sides. It is used to ensure that the pressing time meets the film bonding requirements of the first bonding surface without causing the material of the second bonding surface to overheat and deform. The pressure value in the corresponding safe pressure interval refers to the pressure value in the safe pressure interval corresponding to the selected pressing time. Since the safe pressure time value is calculated by the pressure value, temperature value and pressing parameters, when the pressing time is selected, the pressure value, the first temperature value and the second temperature value corresponding to that pressing time can be determined.

[0047] Specifically, the purpose of the time within the safe pressing time interval is to determine the duration of the pressing operation, preventing the time from being too short or too long from affecting the bonding quality. During operation, a specific time value can be selected from the time interval. For example, the time value selection can be categorized into two specific situations: one is to take the midpoint of the safe pressing time interval [130, 150] seconds, 140 seconds, as the pressing time; the other is to dynamically adjust according to the type of board material, such as selecting the minimum value of 130 seconds for high-density boards to ensure efficiency.

[0048] Preferably, to further improve the quality of sheet metal lamination, this embodiment provides a preferred solution in which the time value within the safe lamination time interval is the midpoint of the safe lamination time interval. This preferred solution, by specifying the time value within the safe lamination time interval as the midpoint of the interval, further optimizes the selection of lamination time parameters, thereby improving the stability and consistency of the lamination process. Setting this feature avoids problems such as lamination times being too short or too long that may occur when using endpoint values ​​of the time interval. For example, too short a time may cause poor film adhesion, while too long a time may cause the sheet metal to overheat and deform. By balancing the lamination requirements of both sides through a centrally selected time value, the impact of time parameter fluctuations on lamination quality is reduced, indirectly supporting the overall solution in improving product qualification rates.

[0049] Finally, pressing both sides of the sheet material together performs the actual pressing action, completing the material bonding. During operation, the pressing equipment simultaneously applies pressure and temperature while timing. For example, after the upper and lower pressure plates close, the set parameters are maintained until the time expires. In application scenarios, the sheet material is automatically pressed after being positioned by a conveyor belt. For instance, the pressing process can be described as the press machine starting after the controller sends a command, heating both sides according to the selected temperature value, applying pressure evenly, and counting down the time. After completion, the sheet material is delivered. Another approach is to use fixed parameters instead of dynamic adjustment within a range. Although this method has lower flexibility, it still achieves the basic pressing function. Through the above operations, step S6 ensures the pressing process is safe and reliable, and the overall solution is complete and feasible.

[0050] The beneficial effects of this embodiment: This embodiment provides a method for controlling sheet metal pressing. First, the pressing parameters of the sheet metal are obtained, including first pressing parameters for the first bonding surface and second pressing parameters for the second bonding surface, providing a data basis for subsequent pressing condition calculations. Then, based on these differentiated pressing parameters, a first temperature range and a first pressure range suitable for the pressing requirements of the first bonding surface, and a second temperature range and a second pressure range suitable for the pressing requirements of the second bonding surface are derived. Next, the intersection of the two pressure ranges is used to determine the safe pressure range, matching the requirement of uniform pressure on both sides of the pressing equipment, ensuring that the pressure value can simultaneously meet the safety requirements of pressing on both sides. Finally, the sheet metal pressing parameters, the two temperature ranges, and the safe pressure range are combined... The first and second pressing time intervals are calculated separately. The intersection of the two time intervals is then taken to obtain the safe pressing time interval, which can be synchronously adapted to the pressing time requirements of both sides. Finally, based on the time value within the safe pressing time interval, the pressure value within the safe pressure interval, and the temperature value within the temperature intervals that are adapted to both sides, the board is pressed synchronously on both sides. The time and pressure values ​​can simultaneously meet the common requirements of both sides, and the temperature values ​​of both sides match the individual requirements of their respective bonding surfaces. This ensures that both sides of the board have suitable pressing temperature, pressure, and time, thereby significantly improving the bonding tightness and yield of the double-sided pressing of the board and effectively improving the pressing quality of the double-sided pressing of the board. Example

[0051] In actual operation, if the initial pressing parameters do not match the subsequent calculation requirements when calculating the final temperature, pressure, and time values, some situations may not be fully considered, resulting in a low degree of matching between the final calculation results and the actual situation. This leads to a deterioration in the pressing quality of the double-sided pressing of the sheet. Therefore, this embodiment provides a preferred solution. In this preferred solution, the pressing parameters include sheet parameters and membrane parameters; the sheet parameters include sheet thickness and sheet compressive strength parameters; the membrane parameters include membrane material parameters and surface texture parameters.

[0052] It should be noted that by further defining the pressing parameters to include both sheet material and film material parameters, and refining the sheet material parameters to include sheet thickness and compressive strength, and the film material parameters to include film material properties and surface texture parameters, the accuracy and comprehensiveness of the parameter definitions are enhanced, thereby optimizing the basis for pressing condition calculations. Setting this feature ensures that the pressing parameters cover multiple dimensions, including the properties of the sheet material itself and the characteristics of the film material, avoiding deviations in pressing conditions caused by parameter generalization. For example, the same parameter might overlook differences in sheet strength or film texture, leading to poor adhesion or deformation. Parameter refinement improves the fitting accuracy and calculation reliability of the pressing process, directly helping to solve the quality instability problem caused by inconsistent material properties in double-sided pressing, and indirectly supporting the overall solution in improving product qualification rate and efficiency.

[0053] Specifically, the pressing parameters, including the sheet material parameters and the membrane material parameters, are crucial for integrating the key attributes of the sheet material and the membrane. They provide comprehensive input for calculations of temperature, pressure, and time intervals, preventing missing parameters from affecting pressing accuracy. During operation, the sheet material parameters and membrane material parameters can be obtained separately through sensor systems or database queries. For example, during the initialization phase of the pressing equipment, a thickness gauge is used to measure the sheet material thickness, and a vision system is used to identify the membrane material. Based on the membrane material, corresponding property parameters are retrieved. Application scenarios include automatic parameter acquisition before the sheet material enters the pressing area in automated production lines. For example, the pressing parameters can be obtained in two ways: one is that the sheet material parameter is wood with a thickness of 10 mm and the membrane material parameter is PVC; the other is that the sheet material parameter is metal with high compressive strength and the membrane material parameter is paper with a shallow texture. These parameters are uniformly input into the calculation system through an integrated processing module.

[0054] The sheet material parameters include sheet thickness and material parameters, ensuring that the pressing pressure does not exceed the sheet's tolerance limit to avoid deformation or damage. During operation, the sheet thickness can be measured in real time using a laser rangefinder or calipers. The sheet material parameters can be obtained through a sensor system or database query, and based on these parameters, a series of parameters for the material, such as stiffness, can be derived. The membrane material parameters, including membrane material parameters and surface texture parameters, describe the chemical and surface properties of the coating material, optimizing temperature and time settings to enhance adhesion. During operation, the membrane material parameters can be identified using an infrared spectrometer or selected from a preset list. The surface texture parameters are measured using a profilometer or image processing system to determine the texture depth and distribution. Application scenarios include parameter input and control systems before coating application. For example, membrane material parameters can include material type (e.g., plastic or rubber) and thermal properties (e.g., softening temperature). Surface texture parameters include texture depth values ​​(e.g., 0.3 mm) and texture density (e.g., 5 lines per centimeter).

[0055] Preferably, to improve the accuracy and versatility of temperature range calculation, this embodiment provides a preferred solution in which the calculation of the first temperature range of the first bonding surface based on the first pressing parameters includes: The minimum effective temperature of the first bonding surface is calculated as follows: T1min=Ts1+Kh·h1+kd·d1-5; The maximum safe temperature of the first bonding surface is calculated as follows: T1max=min(Tn1, Ts1+kh·h1+kd·d1+25); The first temperature range is [T1min, T1max]; The second temperature range of the second pressing surface, calculated based on the second pressing parameters, includes: The minimum effective temperature of the second bonding surface is calculated as follows: T2min=Ts2+Kh·h2+kd·d2-5; The maximum safe temperature of the second bonding surface is calculated as follows: T2max=min(Tn2, Ts2+kh·h2+kd·d2+25); The second temperature range is [T2min, T2max]; Where Tsi is the softening temperature of the membrane material; Tni is the degradation temperature of the membrane material; hi is the texture depth of the membrane material; di is the thickness of the membrane material; kh is the temperature coefficient of texture depth; kd is the temperature coefficient of membrane thickness, and i = 1 or 2.

[0056] It should be noted that the temperature range of the steel plate during the lamination process needs to meet the following conditions: First, it needs to be higher than the film softening temperature Tsi to ensure fluidity and facilitate filling of the texture; second, it needs to be lower than the thermal degradation temperature Tni. If the temperature is higher than the thermal degradation temperature, the film may be burned, resulting in yellowing and failure of the material; finally, it needs to meet the temperature compensation of the texture. The deeper the texture and the greater the density, the higher the temperature compensation is required to reduce the filling resistance. In the calculation formula of this preferred solution, Tsi is the softening temperature to be laminated, which determines the "basic threshold" of the temperature range to ensure that the membrane material has the fluidity required for pressing; Tni is the thermal degradation temperature of the membrane material, which determines the "safe upper limit" of the temperature range to avoid material failure due to overheating; hi is the texture depth of the membrane material, which quantifies the temperature requirements of the texture and achieves precise adaptation of different textures; di is the thickness of the membrane material, which compensates for differences in thermal conductivity and ensures that the membrane material as a whole achieves a uniform flow state; kh is the texture depth temperature coefficient, which builds a quantitative bridge between texture depth and temperature to ensure accurate and controllable temperature compensation; kd is the membrane thickness temperature coefficient, which builds a quantitative bridge between thickness and temperature to compensate for differences in thermal conductivity; -5℃ is the minimum temperature margin, which is compatible with batch differences in materials and improves the robustness of temperature control; +25℃ is the maximum temperature safety margin, which is compatible with equipment temperature fluctuations and reduces the difficulty of hardware control.

[0057] This temperature range calculation formula is designed for double-sided differential pressing scenarios of sheet materials. It's an algorithm model built around the goal of "effective bonding and safe, damage-free balance," combining the rheological properties of thermoplastic materials, the law of thermal conductivity, and engineering practice requirements. The minimum effective temperature is designed with the film material's softening temperature as the core benchmark, ensuring the film reaches a viscous flow state to meet the basic conditions for filling textures. Temperature compensation is added based on texture depth to overcome filling resistance, and temperature compensation is added based on film thickness to balance differences in thermal conductivity. A safety margin is also reserved to accommodate batch variations in materials and equipment temperature detection errors, ensuring uniform flow of the film material. The maximum safe temperature is based on the film material's degradation temperature as an absolute safety threshold that cannot be exceeded, preventing damage due to overheating. Molecular chain breakage and performance failure are addressed by adding a reasonable safety margin to the minimum effective temperature calculation to form an engineering safety upper limit, adapting to the temperature fluctuation characteristics of the equipment. By taking the smaller value between the degradation temperature and the engineering safety upper limit, a dual constraint is formed, which avoids the risk of instantaneous overheating and reserves space for subsequent temperature and pressure coordination adjustments. The overall design allows for independent calculation of temperature ranges based on the different parameters such as material, texture depth, and thickness of the two-sided film materials, adapting to the need for simultaneous pressing of different film materials on both sides. It also works in synergy with the calculation logic of subsequent pressure and time ranges, effectively solving the shortcomings of traditional uniform temperature that cannot meet the differentiated needs of both sides. This ensures that each side receives accurately adapted temperature conditions, balancing the tightness of the bond and the safety of the materials.

[0058] Preferably, in actual operation, to improve the accuracy and versatility of the pressure range calculation, this embodiment provides a preferred solution. In this preferred solution, calculating the first pressure range of the first bonding surface based on the first pressing parameters includes: Calculate the minimum effective pressure on the first mating surface: P1min=kp·(h1·ρ1)+σ0; Calculate the maximum safe pressure on the first mating surface: P1max = min(σ1, σb / 2); The first pressure range is [P1min, P1max]; The second pressure range of the second bonding surface, calculated based on the second pressing parameters, includes: Calculate the minimum effective pressure on the second mating surface: P2min=kp·(h2·ρ2)+σ0; Maximum safe pressure on the second bonding surface: P2max=min(σ2,σb / 2); Second pressure zone [P2min, P2max]; Wherein, kp is the pressure coefficient of the texture; σ0 is the basic bonding pressure; σi is the compressive strength of the bond; σb is the compressive strength of the board; σb / 2 is the upper limit of single-sided pressure of the board; and i = 1 or 2.

[0059] It should be noted that the calculation formula in this embodiment aims to define the "effective and safe" pressing pressure range for each side in scenarios involving differentiated double-sided lamination of the sheet material. This range must ensure a tight bond between the membrane and the sheet material while avoiding overpressure that could damage the membrane or deform the sheet. Therefore, it is first necessary to calculate the minimum effective pressure required for the membrane to fully fill the texture and initially adhere to the sheet. When the pressure is below this value, the surface tension of the membrane and the resistance to filling the texture cannot be overcome, leading to problems such as poor adhesion, residual air bubbles, and unclear texture replication. Simultaneously, the maximum safe pressure also needs to be calculated. Pressure exceeding this value can cause the membrane to tear, crush, or permanently deform the sheet. In this calculation formula, kp is the texture pressure coefficient, which quantifies the texture complexity as a proportional coefficient of pressure increment; hi is the membrane texture depth, used to quantify the longitudinal filling difficulty of the texture; ρi is the membrane texture density, which quantifies the transverse filling difficulty of the texture; σ0 is the basic bonding pressure, which is the "initial contact pressure" between the membrane and the substrate; σi is the membrane compressive strength, which is the maximum pressure that the membrane can withstand; σb is the substrate compressive strength, which is the maximum total pressure that the substrate can withstand.

[0060] The pressure range calculation formula combines material mechanical properties with industrial production equipment constraints to construct an algorithm model. The minimum effective pressure uses the basic bonding pressure as the core benchmark to ensure initial contact between the membrane and the substrate and to expel interfacial air, avoiding bonding gaps and air bubbles caused by insufficient pressure. Simultaneously, the complexity of the texture is quantified based on the combination of the membrane's texture depth and density, and corresponding pressure compensation is supplemented through a texture pressure coefficient to overcome the filling resistance caused by deep textures and high density, ensuring the membrane can fully embed into the substrate texture for a tight fit. The maximum safety pressure establishes a dual safety constraint: the membrane's compressive strength serves as the first layer of protection, preventing damage such as tearing or crushing due to excessive pressure; half of the substrate's compressive strength serves as the second layer of protection, adapting to the substrate. The force characteristics of double-sided extrusion prevent deformation and breakage caused by single-sided pressure exceeding the sheet's tolerance limit. By taking the smaller of the two values ​​to form an absolute safety threshold, it prioritizes ensuring that the material performance is not damaged while adapting to the mechanical transmission law of the pressing equipment. The overall design allows for independent calculation of pressure ranges based on the different parameters such as the texture characteristics and material strength of the two-sided film materials. This perfectly adapts to the needs of simultaneous pressing of different film materials on both sides and works in synergy with the subsequent calculation logic of temperature and time ranges. It effectively solves the shortcomings of traditional uniform pressure that cannot take into account the differentiated needs of both sides, ensuring that each side receives precisely matched pressure conditions. This ensures both the tightness of the texture filling and avoids damage to the material and sheet due to pressure overload, guaranteeing the quality stability of simultaneous pressing of both sides.

[0061] Preferably, in order to improve the accuracy and versatility of the pressing time calculation during actual operation, this embodiment provides a preferred solution in which the pressing time is calculated based on the pressing parameters, temperature range, and safe pressure range as follows: timin=[t0+kt·(hi·ρi)+kd·di]·[1-kT·(Timin-100)]-kp·(Pmin-3) timax=[t0+kt·(hi·ρi)+kd·di]·[1-kT·(Timax-100)]-kp·(Pmax-3) Where t0 is the basic bonding time coefficient, kt is the texture time coefficient, hi is the texture depth, ρi is the texture density, kd is the film thickness time coefficient, di is the film thickness, kT is the temperature correction coefficient, kp is the pressure correction coefficient, and i = 1 or 2. The first pressing time is [t1min, t1max], and the second pressing time interval is [t2min, t2max].

[0062] It should be noted that the core of this set of calculation formulas is to calculate an effective and safe pressing time interval for each bonding surface, so as to achieve coordinated adaptation of pressing parameters, temperature, pressure and time. Among them, timin calculates the shortest time threshold for the membrane material to fully fill the texture and adhere firmly to the board, while timax calculates the longest time threshold for the membrane material to avoid overheating and degradation or deformation of the board. Wherein, t0 is the basic bonding time coefficient, which is the minimum bonding time reference under standard temperature and pressure without texture; kt is the texture time coefficient, which is a proportional coefficient that quantifies texture complexity into time increment; hi is the membrane texture depth, which quantifies the longitudinal filling time of the texture; ρi is the membrane texture density, which quantifies the transverse filling time of the texture; kd is the membrane thickness time coefficient, which quantifies the membrane thickness into a proportional coefficient that quantifies time increment; di is the membrane thickness, which quantifies the heat conduction time of the membrane; kT is the temperature correction coefficient, which is the time correction ratio when the temperature deviates from the standard value; Timin / Timax is the temperature range boundary of the bonding surface, which is the core input for temperature correction; kp is the pressure correction coefficient, which is the time correction ratio when the pressure deviates from the standard value; and Pmin / Pmax is the safety pressure range boundary, which is the core input for pressure correction.

[0063] This formula for calculating bonding time combines material rheological properties with industrial production efficiency requirements to construct a scientific logic. The design of the minimum effective bonding time is based on the basic bonding time as the core benchmark, ensuring that the membrane and the substrate can achieve basic adhesion under standard temperature and pressure conditions without texture. At the same time, the complexity of the texture is quantified according to the combination of the texture depth and density of the membrane, and corresponding time compensation is supplemented by a texture time coefficient. Because the more complex the texture, the longer the time required for membrane filling and penetration. Then, time compensation is supplemented by a thickness time coefficient based on the membrane thickness to balance the difference of slow heat conduction and difficulty in uniform softening of thick membranes. Subsequently, temperature correction is performed based on the set standard temperature. When the temperature is higher than the standard temperature, the membrane fluidity is better, and the bonding time can be appropriately shortened. At the same time, pressure correction is performed based on the set standard pressure. When the pressure is higher than the standard pressure, the bonding efficiency of the membrane and the substrate is higher. The design allows for further reduction in pressing time, ultimately achieving the shortest time threshold that ensures full filling of the texture and strong adhesion. The maximum safe pressing time is consistent with the minimum effective pressing time, only modified by replacing the highest values ​​of the temperature range and the highest values ​​of the safe pressure range. This avoids overheating and degradation of the membrane material and deformation of the board due to excessive time, while also adapting to the temperature and pressure synergy principle, ensuring that the time remains within a safe range even when the temperature and pressure are at their upper limits. The overall design allows for independent calculation of time ranges based on the texture characteristics, thickness, and other differential parameters of the membrane materials on both sides of the board, perfectly adapting to the need for simultaneous pressing of different membrane materials on both sides. Furthermore, it deeply coordinates with the calculation logic of the temperature and pressure ranges mentioned above, ensuring that each side receives a precisely matched pressing time. This guarantees both the sufficiency and stability of the adhesion, while avoiding the impact of excessively long or short times on pressing quality and production efficiency.

[0064] The beneficial effects of this embodiment: This embodiment further defines the pressing parameters, including sheet material parameters and membrane material parameters. Sheet material parameters include sheet thickness and material properties, while membrane material parameters include material properties and surface texture parameters. By further defining the pressing parameters, this embodiment selects parameters that more closely match the temperature, pressure, and time values, thus making the final calculated values ​​more accurate to actual conditions and improving the pressing quality of double-sided sheet pressing. Example

[0065] See Figure 2 and Figure 3 Corresponding to the aforementioned application function implementation method embodiments, this embodiment provides a sheet metal pressing device for implementing Embodiments 1 and 2, including: The pressing assembly is used to press the two sides of the sheet metal together, and includes a first steel plate 1, a second steel plate 2, and a driving device 3; An information acquisition component is used to acquire the pressing parameters of the sheet material, the pressing parameters including the pressing parameters of the first bonding surface and the second bonding surface; An information processing component is used to process the pressing parameters and output control parameters for controlling the pressing component based on the processing results; A control component for controlling the pressing component according to the control parameters.

[0066] It should be noted that this device integrates hardware components for pressing, information acquisition, processing, and control, enabling automated pressing processes, improving pressing accuracy, reducing human error, and enhancing production efficiency and product consistency. It directly supports the optimization of pressing quality across the entire solution. The device includes pressing components, information acquisition components, information processing components, and control components, which work together to ensure the pressing process is executed precisely based on calculated parameters.

[0067] Specifically, the pressing assembly is used to press both sides of the sheet metal together. It includes a first steel plate 1, a second steel plate 2, and a driving device 3. Its function is to physically perform the pressing action, achieving synchronous or opposing pressing of both sides of the sheet metal, avoiding quality fluctuations caused by multiple pressing operations. During operation, the first steel plate 1 and the second steel plate 2 correspond to the two sides of the sheet metal respectively. Pressure and temperature are applied by the driving device 3. For example, during the pressing process, the steel plates are heated and moved to adhere to the sheet metal. Application scenarios include the assembly starting up after the sheet metal is conveyed to the pressing area in an automated pressing line. It is worth noting that the design of the pressing assembly must ensure synchronous pressure on both sides; asynchronous driving may cause the sheet metal to shift.

[0068] The information acquisition component is used to acquire the pressing parameters of the sheet material, including the pressing parameters of the first and second bonding surfaces. Its function is to collect key data required for pressing, providing input for subsequent processing and preventing missing parameters from affecting the calculation of pressing conditions. Operation can be achieved through various sensors or interfaces, such as using a thickness sensor to measure the sheet material thickness or using RFID to read pre-stored parameters. In application scenarios, the component is automatically activated when the sheet material enters the device. For example, the information acquisition component may include a vision system scanning the texture depth on both sides, or a temperature sensor detecting the ambient temperature. Another approach is to query parameters through a database, which, although less real-time, still provides data support. Through the above operations, information acquisition ensures accurate parameter input.

[0069] The information processing component is used to process the pressing parameters and output control parameters based on the processing results. Its function is to convert the raw parameters into operable control commands, realize the calculation of temperature, pressure and time intervals, and optimize the pressing conditions. The operation component performs calculations through built-in algorithms or processors, for example, using a microcontroller to run the method steps of Embodiments 1 and 2, and outputs a safe pressure interval or a safe pressing time interval. Application scenarios include generating control signals after real-time processing of sensor data. For example, the information processing component can be one of the following two cases: one is to use an application-specific integrated circuit to execute a fixed algorithm, and the other is to use a general-purpose processor in conjunction with software calculation, but this embodiment is based on a processor.

[0070] Specifically, the control component controls the pressing component according to control parameters. Its function is to receive processed parameters and drive the pressing action, ensuring the pressing process is executed according to calculated conditions and avoiding parameter deviations. During operation, the component converts control parameters such as pressure or temperature values ​​into drive signals, for example, by adjusting the speed or pressure of the drive device through a PLC controller. In application scenarios, the control component monitors the pressing status in real time and makes adjustments. For example, the control component may include a digital signal processor outputting a PWM signal to control the heater, or a relay module switching the pressing equipment. Another option is to use an analog controller, although with lower precision, it can still achieve basic control. Through the collaboration of the above components, the device fully implements the pressing method, ensuring the feasibility and reliability of the solution. Example
