Description

Methods, apparatus, systems, equipment and media for composite asymmetric aluminum sandwich panels Technical Field

[0001] This invention relates to the field of home decorative panel industrial production, and more specifically, to a composite method, apparatus, system, equipment, and medium for asymmetric aluminum sandwich panels. Background Technology

[0002] Aluminum sandwich panels are a high-performance composite decorative material widely used in the construction and home furnishing industries. Their standard production process involves continuously rolling and bonding two layers of aluminum coils with a core material. During this process, tensile force is applied to the aluminum coils to ensure stable transport and composite quality. In recent years, driven by diversified market demands, cost optimization, and specific performance requirements, asymmetric aluminum sandwich panels have emerged, featuring differentiated thicknesses between the upper and lower aluminum layers.

[0003] However, if the same tensile force is applied to the two layers of aluminum coil using the traditional process, the thinner aluminum coil, due to its smaller cross-sectional area, will bear much greater stress and strain than the thicker aluminum coil. After the two are combined, an unbalanced internal stress field will be formed inside. After the aluminum plate in the composite aluminum sandwich panel is removed from the tension constraint of the production line, the release of internal stress will cause the aluminum sandwich panel to undergo irreversible warping deformation towards the thicker aluminum plate side, making flatness control extremely difficult. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide a method, apparatus, system, equipment and medium for composite asymmetric aluminum sandwich panels, which can determine the tensile force of two aluminum coils of different thicknesses before composite to ensure that they have the same tensile strain, thereby obtaining a symmetric aluminum sandwich panel without stress warping problems.

[0049] (I) Background information on aluminum sandwich panels:

[0050] Aluminum sandwich panels, as a high-performance composite decorative material, are widely used in the construction and home furnishing industries. Their standard production process involves continuously rolling and bonding two layers of aluminum coils with a core material. During the bonding process, a certain tensile force (tension) needs to be applied to the aluminum coils to ensure smooth transport and bonding quality. A core process principle is that, to ensure the flatness and warp-free finish of the finished panel, the tensile strain (i.e., the elongation of the material along the tensile direction) of the two aluminum layers must be consistent when they enter the bonding unit.

[0051] In traditional aluminum sandwich panel production, the top and bottom aluminum sheets are typically of the same thickness. However, in recent years, with the diversification of market demands, cost optimization, and the emergence of specific performance requirements, the industry has begun to design and produce aluminum sandwich panels with an asymmetrical structure. In this design, the top and bottom aluminum sheets are intentionally designed with different thicknesses. For example, the top aluminum sheet, which directly faces the external environment and requires higher weather resistance and impact resistance, is designed to be thicker, while the bottom aluminum sheet is designed to be thinner, thereby effectively reducing material costs and the overall weight of the sheet while ensuring key performance characteristics.

[0052] While this asymmetric design brings significant economic or performance advantages, it also presents more severe and fundamental technical challenges to warp control in the production process.

[0053] Based on the fundamental principles of mechanics of materials, strain ( It is proportional to the stress (σ) (σ=E) The stress is equal to the tensile force (F) divided by the cross-sectional area (A), i.e., σ = F / A. For sheet metal, the cross-sectional area is determined by its width and thickness.

[0054] When producing this type of asymmetrical sheet metal, since the thicknesses of the upper and lower aluminum plates are predetermined to be unequal, if the traditional approach of applying the same tensile force (F) to both layers is still used, then according to the stress formula above, the thinner aluminum plate, due to its smaller cross-sectional area (A), will inevitably bear a much greater stress (σ) than the thicker plate, and thus generate a larger strain. ).

[0055] When two aluminum plates with significantly different strains are forcibly bonded together, a huge, unbalanced internal stress field is "locked" inside the plate. Once the plate is released from the tension constraint of the production line, this internal stress will inevitably be released, causing severe and irreversible warping deformation of the plate towards the side with smaller strain (i.e., thicker). This makes the flatness control of asymmetrical structural plates an industry-wide technical bottleneck.

[0056] Currently, most existing production lines and their tension control systems are designed for symmetrical sheet metal structures. They lack the necessary logic and capability to proactively address the inherent stress differences arising from the design itself. Relying solely on operator experience to adjust two completely different tensile forces makes precise strain matching virtually impossible. Therefore, without scientific calculation methods and precise control equipment, the production yield of asymmetrical aluminum sandwich panels is extremely low, severely limiting the promotion and application of this high-performance, cost-effective product.

[0057] (II) Introduction to traditional techniques for avoiding warping problems caused by improper tension:

[0058] To address the warping problem caused by improper tension during aluminum sandwich panel production, existing technologies primarily rely on manual, experience-based control methods. The core objective of these methods is to maintain stable tension, but they cannot predict the required tension for the desired elongation. This often results in the initial production of flat, qualified products, requiring multiple adjustments to achieve the standard, leading to waste. Traditional methods for controlling constant tension include:

[0059] 1. Open-loop taper tension control scheme: This is a relatively basic form of automated control. Based on pre-input parameters such as the initial diameter and material thickness of the aluminum coil, the system calculates the remaining diameter of the coil using a PLC (Programmable Logic Controller) or a dedicated controller. As the coil diameter decreases, the system automatically and gradually reduces the torque output of the braking device (such as a magnetic powder brake or torque motor) according to a preset taper curve. The aim is to maintain a constant tensile force as much as possible throughout the entire diameter change process.

[0060] Limitations: This solution is an open-loop control system, meaning the system only "estimates" and "executes" the tension, but does not measure or provide feedback on the actual tension results. It cannot respond to unexpected disturbances such as material thickness fluctuations or changes in equipment operating resistance. More importantly, it still requires manually setting an initial tension value, failing to address the core issue: when the upper and lower aluminum plates have different thicknesses, what initial tension values ​​should be set to ensure consistent strain?

[0061] 2. Closed-loop constant tension control scheme: This is currently the most mainstream and advanced automation control scheme in industrial applications. The system installs tension sensors along the aluminum conveying path on the production line, measuring tension in real time through two mainstream methods:

[0062] (a) Tension sensor (Load Cell): A measuring roller is installed on the load cell. When the aluminum material passes through the roller, its pressure is directly measured by the sensor, thus obtaining an accurate real-time tension value.

[0063] (b) Floating Roll / Dancer Roll: The position of a floating roller loaded by a cylinder or spring indirectly reflects the tension. When the tension changes, the floating roller swings up and down, and its position change is detected by a sensor.

[0064] The system compares the real-time tension value measured by the sensor with the "target tension value" preset by the operator, calculates the deviation through the PID (proportional-integral-derivative) algorithm, and automatically adjusts the output of the brake or drive motor to keep the actual tension accurately at the set target value.

[0065] Limitations: Although a closed-loop control system can achieve high-precision constant tension control, it is merely a faithful "executor." The core task of the system is to maintain the operator-set tensile force (F) constant. However, in the production of asymmetrical structural panels, the key issue is not maintaining a constant tensile force, but rather calculating two different target tensile force values ​​based on different thicknesses (A), thereby controlling the final strain (F). )equal.

[0066] (iii) Deficiencies of the prior art:

[0067] In summary, existing technologies, whether manual, open-loop, or advanced closed-loop control, share a common and fundamental flaw: their design philosophy is limited to "how to maintain a constant tensile force," completely failing to provide a solution for "how to determine this target tensile force to ensure consistent strain." They lack an upstream decision-making module that performs scientific calculations based on the actual thickness of the material. Therefore, when dealing with asymmetric aluminum sandwich panels whose thickness varies due to the design itself, all existing technological solutions cannot fundamentally solve the warping problem caused by unbalanced internal stress.

[0068] (III) Technological Development Trends:

[0069] In the field of high-performance composite panel manufacturing, especially for process control of complex products such as asymmetric structures, technological development is showing a profound shift from "online passive adjustment" to "offline active calibration" and from "relying on theoretical models" to "respecting physical measurements".

[0070] 1. Trend 1: Shifting the quality control point from "process control" to "pre-calibration":

[0071] Traditional technological approaches, whether relying on human experience or automated closed-loop systems, focus on maintaining a setpoint during production—a "process-based control" logic. However, for inherently unbalanced systems like asymmetrical panels, the core challenge isn't "maintaining," but rather "setting"—that is, no one knows the correct setpoint before production begins. Therefore, the inevitable trend in industry development is to shift quality control upstream, from "process control" to "pre-production calibration." This involves determining all key process parameters in advance through scientific and low-cost experimental methods before consuming large amounts of raw materials for production.

[0072] 2. Trend Two: From "Indirect Theoretical Calculation" to "Direct Physical Equivalence" Parameter Acquisition:

[0073] When faced with the problem of setting tension for plates of varying thicknesses, an intuitive approach is to perform theoretical calculations (e.g., using the formula F1 / F2=A1 / A2). However, the fatal flaw of this method is its reliance on idealized material parameters (such as the elastic modulus E), while the performance fluctuations between actual batches of materials introduce significant errors. Therefore, the trend in technological development is to move away from dependence on uncertain theoretical parameters and towards finding an equivalent testing method that can directly reflect the true physical properties of materials.

[0074] 3. Trend Three: The Engineering Path from "Complex Online Monitoring" to "Simplified Offline Solutions":

[0075] To address the warping problem, one industry trend is to develop expensive and complex online, real-time monitoring systems, such as using machine vision to monitor minute deformations of the sheet material throughout the entire process. However, such solutions often involve huge investments, are difficult to maintain, and have poor adaptability to high-speed production lines, making widespread adoption extremely challenging. Therefore, a more practical and engineering-valuable development trend is to seek a simple, elegant solution that achieves maximum results with minimal effort.

[0076] In summary, existing methods rely on experience or simple closed-loop constant tension control, which cannot fundamentally eliminate the problem of internal stress warping in finished sheet materials caused by strain mismatch.

[0077] Therefore, the embodiments of this application aim to solve the technical problem in the prior art that when producing aluminum sandwich panels with asymmetrical structures (i.e., different thicknesses of upper and lower aluminum plates), it is impossible to determine in advance the precise tensile force required to be applied to each of the upper and lower aluminum plates to ensure that they have the same tensile strain.

[0078] Therefore, embodiments of this application provide a method, apparatus, system, device, and medium for composite asymmetric aluminum sandwich panels. The method includes: obtaining a first thickness corresponding to a first aluminum coil to be composited and a second thickness corresponding to a second aluminum coil, and a first preset tensile force corresponding to the first aluminum coil or a second preset tensile force corresponding to the second aluminum coil; determining a loading ratio coefficient between the first aluminum coil and the second aluminum coil based on the first thickness corresponding to the first aluminum coil and the second thickness corresponding to the second aluminum coil; the loading ratio coefficient is used to characterize the ratio of the tensile force required by the first aluminum coil and the second aluminum coil under the condition of applying the same lateral displacement. The method involves: calculating the target tensile force of the second aluminum coil based on the first preset tensile force and loading ratio coefficient corresponding to the first aluminum coil; or calculating the target tensile force of the first aluminum coil based on the second preset tensile force and loading ratio coefficient corresponding to the second aluminum coil; and then combining the first aluminum coil and the second aluminum coil based on the first preset tensile force and the target tensile force corresponding to the second aluminum coil to obtain an asymmetric aluminum sandwich panel; or combining the first aluminum coil and the second aluminum coil based on the target tensile force and the second preset tensile force corresponding to the second aluminum coil to obtain an asymmetric aluminum sandwich panel. The composite method provided in this application allows for the pre-determining of the precise tensile force required for each of the upper and lower aluminum plates, eliminating the problem of internal stress warping in the finished product due to strain mismatch, improving the production qualification rate, and accelerating the promotion and application of such high-performance products.

[0079] The following is a detailed description of a composite method for an asymmetric aluminum sandwich panel provided in the embodiments of this application.

[0080] Referring to Figure 1, which is a schematic flowchart of a composite method for an asymmetric aluminum sandwich panel provided in an embodiment of this application, the exemplary steps of the embodiment of this application are described below:

[0081] S101. Obtain the first thickness corresponding to the first aluminum coil to be laminated and the second thickness corresponding to the second aluminum coil, as well as the first preset tensile force corresponding to the first aluminum coil or the second preset tensile force corresponding to the second aluminum coil.

[0082] In this embodiment, the first aluminum coil and the second aluminum coil are aluminum coils of different thicknesses that need to be laminated into an asymmetric aluminum sandwich panel. The first thickness is the thickness of the first aluminum coil, and the second aluminum coil is an aluminum coil of a second thickness. The first preset tensile force is the tensile force required by the laminating personnel for the first aluminum coil during lamination. The second preset tensile force is the tensile force required by the laminating personnel for the second aluminum coil during lamination.

[0083] It should be noted that the laminating personnel only set the tensile force required for one of the aluminum coils during lamination, while the tensile force required for the other aluminum coil during lamination needs to be determined by the method provided in the embodiments of this application, so as to ensure that the first aluminum coil and the second aluminum coil have the same tensile strain, thereby eliminating the problem of internal stress warping of the finished sheet caused by strain mismatch.

[0084] It should be noted that the deflection angle generated by the first aluminum coil under the corresponding first preset tensile force or the second aluminum coil under the corresponding second preset tensile force is less than the preset deflection angle (e.g., 10 degrees). Under this preset deflection angle, the lateral force of the aluminum coil is linearly related to the tensile strain.

[0085] S102. Determine the loading ratio coefficient between the first aluminum coil and the second aluminum coil based on the first thickness and the second thickness.

[0086] In the embodiments of this application, the loading ratio coefficient is used to characterize the ratio of the tensile force required by the first aluminum coil and the second aluminum coil under the condition of applying the same lateral displacement; that is, when the value obtained by dividing the tensile force applied by the first aluminum coil by the tensile force applied by the second aluminum coil is equal to the value corresponding to the loading ratio coefficient, the lateral displacement generated by the first aluminum coil is the same as the lateral displacement generated by the second aluminum coil, that is, the tensile strain of the two is the same.

[0087] Specifically, embodiments of this application provide two methods for determining the loading ratio coefficient between the first aluminum coil and the second aluminum coil:

[0088] (a) The implementation steps of the first method are as follows:

[0089] Step 1: Determine whether the pre-established loading ratio coefficient table contains the loading ratio coefficients for aluminum coils corresponding to the first and second thicknesses.

[0090] In this embodiment of the application, the loading ratio coefficient table is used to store the loading ratio coefficient between every two thicknesses of aluminum coil.

[0091] Step 2: If included, the loading ratio coefficient of the aluminum coil is determined as the loading ratio coefficient between the first aluminum coil and the second aluminum coil.

[0092] In this embodiment of the application, if the loading ratio coefficient table includes aluminum coil loading ratio coefficients corresponding to the first thickness and the second thickness, the aluminum coil loading ratio coefficient in the loading ratio coefficient table can be directly determined as the loading ratio coefficient between the first aluminum coil and the second aluminum coil.

[0093] Step 3: If not included, then calibrate the loading ratio coefficient between the first calibrated aluminum coil of the first thickness and the second calibrated aluminum coil of the second thickness to obtain the loading ratio coefficient between the first aluminum coil and the second aluminum coil.

[0094] In this embodiment of the application, if the loading ratio coefficient table does not include the loading ratio coefficients for the first and second thicknesses of the aluminum coil, then based on the calibration method of calculating the required tensile force through geometric deformation, the loading ratio coefficients of the first calibrated aluminum coil of the first thickness and the second calibrated aluminum coil of the second thickness are calibrated to obtain the loading ratio coefficient between the first and second aluminum coils. Here, the calibrated aluminum coil refers to the aluminum coil used to calibrate the loading ratio coefficient. The specific calibration process is as follows:

[0095] i. Under at least one preset lateral displacement condition, mechanical property tests are performed on the first calibrated aluminum coil and the second calibrated aluminum coil respectively to obtain the lateral force corresponding to the first calibrated aluminum coil and the lateral force corresponding to the second calibrated aluminum coil.

[0096] In this embodiment of the application, referring to FIG2, a calibration principle diagram provided in the embodiment of the application is shown. To determine the original length of the aluminum coil (i.e., the sheet material in Figure 2), This refers to the length between the preset lateral loading point and the upper clamp after applying a lateral force. Referring to Figure 2, the steps for conducting mechanical property tests on any calibrated aluminum coil under any preset lateral displacement condition are explained:

[0097] a. Fix the calibrated aluminum coil between the upper and lower clamps, and keep the aluminum coil flat (vertical).

[0098] In this application embodiment, the aluminum coil is calibrated. Fixed between the upper and lower clamps, under gravity or initial tensile force Under the action of [something], it remains flat; at this time, the calibrated aluminum coil [is in good condition]. The force is Considering the flattened state as the initial condition, the calibration aluminum coil is assumed to be... The strain generated at this time is .

[0099] b. At the preset transverse loading point of the calibrated aluminum coil, a transverse force is applied by the loading mechanism to cause the calibrated aluminum coil to produce the preset transverse displacement.

[0100] In the embodiments of this application, when calibrating aluminum coils A preset lateral loading point is set in the middle, and a lateral force is applied through a loading mechanism (such as a wheel axle or a lateral thrust device). (or lateral force increment) to ensure that a lateral force is applied Then, a fixed preset lateral displacement is generated. At this time, due to the calibration of aluminum coils When the preset lateral displacement is generated The deflection angle afterward is .

[0101] In addition, the force sensor measured the calibrated aluminum coil. When the same preset lateral displacement is generated At that time, the magnitude of the applied lateral force .

[0102] ii. Determine the loading ratio coefficient between the first and second aluminum coils based on the ratio of the lateral forces of the first and second calibrated aluminum coils under at least one same preset lateral displacement condition.

[0103] In the embodiments of this application, based on the mechanical equilibrium relationship, it is known that when the deflection angle of the aluminum coil caused by lateral displacement is very small (generally within 10 degrees), the deflection of the aluminum coil satisfies an approximately linear relationship; therefore, it can be considered that the lateral force (or the increment of the lateral force) is linearly related to the effective tensile strain, thereby enabling the calibration of the loading ratio coefficient.

[0104] The mechanical equilibrium relationship is as follows: the lateral loading causes the aluminum coil to be subjected to force from... Become ; For the lateral force The additional tensile force caused; When the temperature is very low, it can be considered a linear system. The main cause of strain in the aluminum coil is the transverse force, i.e. After deflection, the upper and lower portions of the aluminum coil elongate equally, satisfying the requirement of strain consistency. , ,and .

[0105] Specifically, based on the ratio of the lateral forces of the first and second calibrated aluminum coils under at least one identical preset lateral displacement condition, a loading ratio coefficient between the first and second aluminum coils is determined. This includes: if the number of preset lateral displacement conditions is 1, then the ratio of the lateral forces of the first and second calibrated aluminum coils under that preset lateral displacement condition is determined as the loading ratio coefficient between the first and second aluminum coils. If the number of preset lateral displacement conditions is greater than or equal to 2, then the average value of the ratios of the lateral forces of the first and second calibrated aluminum coils under all identical preset lateral displacement conditions is determined as the loading ratio coefficient between the first and second aluminum coils.

[0106] In addition, after obtaining the loading ratio coefficient between the first aluminum coil and the second aluminum coil through the above calibration method, the loading ratio coefficients of the aluminum coils corresponding to the first thickness and the second thickness are stored in the loading ratio coefficient table.

[0107] (ii) The implementation steps of the second method are as follows: Substitute the first thickness and the second thickness into the loading ratio coefficient calculation model to obtain the loading ratio coefficient between the first aluminum coil and the second aluminum coil; the loading ratio coefficient calculation model is used to describe the relationship between the thickness of any two aluminum coils and the corresponding loading ratio coefficient.

[0108] The steps for constructing the loading ratio coefficient calculation model are as follows: using the aforementioned loading ratio coefficient calibration method, determine the loading ratio coefficient between two aluminum coils of different thicknesses; then, perform data fitting on the loading ratio coefficients between all two aluminum coils of different thicknesses to obtain the loading ratio coefficient calculation model.

Calculate the target tensile force corresponding to the second aluminum coil based on the first preset tensile force and the loading ratio coefficient corresponding to the first aluminum coil; or calculate the target tensile force corresponding to the first aluminum coil based on the second preset tensile force corresponding to the second aluminum coil and the loading ratio coefficient.

[0110] In this embodiment, when the first preset tensile force corresponding to the first aluminum coil is obtained, the target tensile force corresponding to the second aluminum coil is calculated based on the first preset tensile force corresponding to the first aluminum coil and the loading ratio coefficient. When the second preset tensile force corresponding to the second aluminum coil is obtained, the target tensile force corresponding to the first aluminum coil is calculated based on the second preset tensile force corresponding to the second aluminum coil and the loading ratio coefficient.

[0111] Specifically, the target tensile force corresponding to the second aluminum coil is calculated based on the first preset tensile force corresponding to the first aluminum coil and the loading ratio coefficient, including: calculating the ratio of the first preset tensile force to the loading ratio coefficient (i.e., the first preset tensile force divided by the loading ratio coefficient to obtain the value), and obtaining the target tensile force corresponding to the second aluminum coil.

[0112] Specifically, the target tensile force corresponding to the first aluminum coil is calculated based on the second preset tensile force and the loading ratio coefficient corresponding to the second aluminum coil, including: calculating the product of the second preset tensile force and the loading ratio coefficient (i.e., the second preset tensile force multiplied by the loading ratio coefficient) to obtain the target tensile force corresponding to the first aluminum coil.

[0115] In summary, compared with the prior art, the capabilities of this application have the following significant advantages:

[0116] (1) Higher accuracy and repeatability: Due to the introduction of an absolute and standardized test benchmark, the cumulative error and uncertainty in the iterative search process are eliminated, making the results of each calibration highly consistent, with excellent repeatability and further improved accuracy.

[0117] (2) The physical meaning is clearer: by applying a transverse force, the effective force that generates the target strain is determined and further converted into a loading ratio coefficient. The physical meaning is clear, which facilitates data traceability for quality control and process theory analysis.

[0118] (3) More direct application: Based on the tensile force loading value of one side of the aluminum coil, the tensile force of the other side of the aluminum coil required for production can be directly output. Operators do not need to perform secondary calculations and can directly use it to set the tensile force controller of the production line, which reduces the complexity of operation and the risk of error.

[0119] (4) Great potential for standardization: The “standard geometric deformation state” defined in the embodiments of this application can become a common test standard in the industry, which facilitates data comparison and process exchange between different manufacturers and different equipment, and has the potential to be promoted as a standardized test method in the industry.
