[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0017] Embodiment 1: Please refer to Figure 1 , Figure 1 which is a schematic flow chart of the method for processing laminates in the embodiments of the present invention. The method is applied to a laminate processing production line, and the laminate processing production line includes a plurality of unwinding devices, a polishing machine, a plurality of heating devices, a rolling device, a shearing mechanism, and a winding machine; the method includes: S11: Based on the material parameters and processing attributes of each metal sheet, match the unwinding control parameters of the corresponding unwinding device, and each unwinding device transmits each metal sheet to the polishing machine based on the corresponding unwinding control parameters; In the specific implementation process of the present invention, the matching of the unwinding control parameters of the corresponding unwinding device based on the material parameters and processing attributes of each metal sheet includes: determining the starting rotation speed of each corresponding unwinding device based on the material parameters of each metal sheet in combination with the coil diameter data; matching the operating rotation speed of each corresponding unwinding device based on the processing attributes of each metal sheet, and taking the starting rotation speed and the operating rotation speed as the unwinding control parameters of the corresponding unwinding device.

[0018] Specifically, the starting rotation speed of each corresponding unwinding device is determined based on the material parameters of each metal sheet in combination with the coil diameter data. The material parameters include the material type, tensile properties, thickness, etc. of the metal sheet, and the coil diameter data includes the winding radius of the metal sheet and the unwinding parameters of the unwinding device, etc. The starting rotation speed of each corresponding unwinding device is matched in the database through the material parameters of each metal sheet in combination with the coil diameter data. The operating rotation speed of each corresponding unwinding device is matched based on the processing attributes of each metal sheet, and the starting rotation speed and the operating rotation speed are taken as the unwinding control parameters of the corresponding unwinding device. The processing attribute is the processing method and process of the value metal sheet. The intermittent stop parameters for each metal sheet, such as the intermittent stop duration and the intermittent stop distance, etc., are determined according to the processing attributes of each metal sheet. The operating rotation speed of each unwinding device is determined according to the intermittent stop parameters, and the starting rotation speed and the operating rotation speed are taken as the unwinding control parameters of the corresponding unwinding device. Different metal sheets are unwound by different unwinding devices. At the same time, in order to synchronize the subsequent processing, the starting rotation speed and the operating rotation speed can be adjusted so that each metal sheet can be transmitted to the polishing machine simultaneously. Each unwinding device transmits each metal sheet to the polishing machine based on the corresponding unwinding control parameters.

[0019] S12: Determine corresponding polishing information based on the roughness analysis and polishing influence analysis of each metal sheet. The polishing machine polishes each metal sheet based on the corresponding polishing information and transfers the polished metal sheets to the first heating device; In the specific implementation process of the present invention, the determination of the corresponding polishing information based on the roughness analysis and polishing influence analysis of each metal sheet includes: performing apparent feature value analysis on the apparent images of each metal sheet to obtain corresponding apparent feature values, and determining the first roughness data of each metal sheet based on the apparent feature values; inputting the apparent images of each metal sheet into a roughness analysis model to obtain second roughness data, where the roughness analysis model includes a feature extraction network, a cross-mixed attention module, and a graph convolutional channel attention module; determining target roughness data based on the first roughness data and the second roughness data; performing material polishing influence analysis and flatness polishing influence analysis based on the material parameters and flatness of each metal sheet to obtain first polishing influence data and second polishing influence data; performing environmental polishing influence analysis based on real-time environmental information using a topology network to obtain third polishing influence data; determining the corresponding polishing information based on the target roughness data, the first polishing influence data, the second polishing influence data, and the third polishing influence data.

[0020] Specifically, the roughness of the metal sheet is usually not recorded in its parameter table, but its roughness is one of the factors determining the polishing information. Therefore, it is necessary to analyze the roughness of each metal sheet. Analyze the apparent feature values of the apparent images of each metal sheet, collect the apparent images of each metal sheet through the corresponding imaging device, divide the apparent images into grids to obtain the apparent image grid set, perform discrete cosine transform on each apparent image grid to obtain discrete cosine coefficients, extract the direct current coefficient and the alternating current coefficient according to the discrete cosine coefficients, calculate the feature values according to the direct current coefficient and the alternating current coefficient, calculate the average value of the feature values of each grid to obtain the corresponding apparent feature value, and determine the first roughness data of each metal sheet based on the apparent feature value, that is, match the first roughness of each metal sheet according to the apparent feature value. Input the apparent images of each metal sheet into the roughness analysis model to obtain the second roughness data. The roughness analysis model includes a feature extraction network, a cross-mixed attention module, and a graph convolutional channel attention module. The apparent sample images of the metal sheet samples at the same position are collected by configuring image acquisition devices with different light sources as the training image set. The cross-mixed attention module calculates the self-attention mechanism using the features of different rows and columns. It extracts the feature information of different light sources and performs spatial feature fusion on the feature information. The graph convolutional channel attention module calculates the correlation between each channel between different light sources in a self-attention manner as the information of the edges in the graph convolution and splices them in the channel dimension to obtain the mixed channel feature information. The feature extraction network is a multi-branch structure. The initial roughness analysis model is trained through the training image set to obtain a trained roughness analysis model. Training the model with the apparent sample images of metal sheets with different light sources can avoid the influence of the apparent images of metal sheets on the roughness analysis of the model. At the same time, the cross-mixed attention module and the graph convolutional channel attention module are introduced, enabling the model to have stronger feature learning ability, improving the analysis efficiency and accuracy, and finally outputting the second roughness through the roughness analysis model. Determine the target roughness data based on the first roughness data and the second roughness data. The target roughness can be calculated through the first roughness data, the second roughness data, and their corresponding weight coefficients. Calculating the target roughness data through the first roughness data and the second roughness data can avoid the one-sidedness and limitations brought by single roughness analysis.Based on the material parameters and flatness of each metal sheet, material polishing impact analysis and flatness polishing impact analysis are carried out. Different material parameters and flatness of the metal sheet will affect polishing. The flatness can be the difference between the highest point and the lowest point between the surface of each metal sheet and a preset reference plane. Input the material parameters of each metal sheet into the material polishing impact analysis model to obtain the first polishing impact data, that is, the impact degree of different materials on polishing. Input the flatness of each metal sheet into the flatness polishing impact analysis model. The material polishing impact analysis model and the flatness polishing impact analysis model can use a deep convolutional neural network to obtain the second polishing impact data, that is, the impact degree of different flatness on polishing. Based on the topological network, environmental polishing impact analysis is carried out using real-time environmental information. Detect the real-time environmental information of the current environment. The real-time environmental information includes air dust particles, temperature, humidity, etc. For example, if there are too many air dust particles, they will adhere to the surface of the metal sheet, resulting in scratches during the polishing process. If the temperature is too high, it will accelerate the volatilization of the polishing machine, etc. A feature data matrix is constructed through the polishing state environmental impact record data set. According to the feature data matrix, several environmental impact factors are generated. The several environmental impact factors are evaluated to obtain the corresponding environmental impact characteristic values. A topological network is constructed through the environmental impact factors and the corresponding environmental impact characteristic values. Input the real-time environmental information into the topological network to obtain the impact degree of the environmental information on polishing, that is, obtain the third polishing impact data. Determine the corresponding polishing information based on the target roughness data, the first polishing impact data, the second polishing impact data, and the third polishing impact data. Determine the target polishing impact data according to the first polishing impact data, the second polishing impact data, and the third polishing impact data. The target polishing impact data can be determined through weight coefficients. Determine the corresponding polishing information for each metal sheet according to the target roughness data and the target polishing impact data. The polishing machine polishes each metal sheet based on the corresponding polishing information to obtain each polished metal sheet and transmits each polished metal sheet to the first heating device.

[0021] S13: The first heating device preheats each polished metal sheet based on the first adaptive controller and transmits the preheated metal sheets to the rolling device; In the specific implementation process of the present invention, the first heating device preheats each polished metal sheet based on a first adaptive controller, including: constructing a first adaptive controller based on a PID controller and a state error system; during the preheating process of each polished metal sheet by the first heating device, calculating a first deviation value between the current temperature of each polished metal sheet and a first preset target temperature; obtaining the temperature change curve of the preheating of past metal sheets under PID parameter control, and establishing fuzzy rules based on the temperature change curve; generating an adjustment control parameter of the first heating device by combining the first deviation value with the first adaptive controller and the fuzzy rules, and optimizing the adjustment control parameter based on the whale optimization algorithm to obtain an optimized adjustment control parameter; the first heating device adjusts the temperature during the preheating process based on the optimized adjustment control parameter.

[0022] Further, constructing the first adaptive controller based on the PID controller and the state error system includes: establishing an object model of each polished metal sheet, constructing a fractional-order complex network system based on the object model, and constructing a state error system based on the fractional-order complex network system; calculating a transfer function based on a preset proportional coefficient, a preset integral coefficient, and a preset differential coefficient, and generating a conventional PID controller based on the transfer function; performing parameter tuning on the conventional PID controller to obtain a PID controller after parameter tuning; constructing a first adaptive controller based on the PID controller after parameter tuning and the state error system.

[0023] Specifically, the polished metal sheets are transported to the first heating device for preheating, so that each metal sheet has viscosity after preheating, so as to be able to roll each metal sheet subsequently. During the preheating process, the heating temperature of the metal sheet will inevitably deviate. In this regard, the temperature needs to be adjusted in time according to the deviation to avoid affecting subsequent processing. An object model of each polished metal sheet is established. The object model is an abstraction of the entity of each metal sheet, which is used as the controlled object. Through the controlled object and the corresponding function, a preset-level abstraction is made, and then the corresponding object model is formed. Based on the object model, a fractional-order complex network system is constructed, and a differential equation corresponding to the object model is established. The fractional-order derivative is taken as the fractional-order order, and the fractional-order derivative is the fractional-order derivative in the sense of Caputo. The fractional-order complex network system is constructed by using the corresponding differential equation through the fractional-order order. Based on the fractional-order complex network system, a state error system is constructed. Considering the existence of uncertainty and unpredictable non-linear states, a non-periodic orbit and an equivalent perturbation of the parameter corresponding to the non-linear state are introduced to construct the target state equation. Based on the target state equation, the state error system between the object model and the fractional-order complex network system is constructed. The transfer function is calculated based on the preset proportional coefficient, preset integral coefficient, and preset differential coefficient. Based on the transfer function, a conventional Proportion Integration Differentiation (PID) controller is generated. The parameters of the conventional PID controller are tuned. Based on the object model, an equivalent treatment is performed to obtain an equivalent model, and the equivalent model is decomposed and calculated to obtain the first-order derivative and the second-order derivative. Based on the first-order derivative and the second-order derivative, a first-order inertia transfer function is generated by combining a preset filtering constant. The first-order inertia transfer function is decomposed to obtain the target parameters, and the parameters of the conventional PID controller are tuned based on the target parameters to obtain the PID controller with tuned parameters. Based on the PID controller with tuned parameters and the state error system, a first adaptive controller is constructed. The equivalent perturbation of the state error system is observed through an extended state observer to obtain an extended state vector. The extended state feedback compensation is obtained by using the preset bandwidth parameter through the extended state vector. The first adaptive controller is constructed according to the extended state feedback compensation and the PID controller with tuned parameters. During the preheating process of the polished metal sheets by the first heating device, the current temperature of each metal sheet is detected by the temperature detector built in the first heating device, and the first deviation value between the current temperature of each polished metal sheet and the first preset target temperature is calculated.Obtain the temperature change curve of the preheating of past metal sheets under PID parameter control. By using PID parameters to simulate the preheating process of past metal sheets, corresponding data is obtained. Based on the corresponding data, the temperature change curve is plotted, and then the temperature change curve is stored in the corresponding database. Through the corresponding database, the temperature change curve can be quickly obtained, and fuzzy rules are established based on the temperature change curve. The dynamic characteristics of temperature change are extracted from the temperature change curve. By the dynamic characteristics, an adjustment speed rule, a static error elimination rule, and a controller oscillation error elimination rule are set. The adjustment speed rule, the static error elimination rule, and the controller oscillation error elimination rule constitute the fuzzy rules. The adjustment speed rule is that when the current real-time temperature is much lower than the preset target temperature, the adjustment speed should be increased to reach the preset target temperature as soon as possible. When the current real-time temperature is lower than the preset target temperature, but the difference between it and the preset target temperature is not large, the adjustment speed can be appropriately slowed down. The static error elimination rule is that in order to make the temperature of the heating device reach the preset target temperature value as soon as possible and be stable, the integral action should be increased in the adjacent area of the preset target temperature. The controller oscillation error elimination rule is to introduce an early differential control signal to quickly correct the deviation generated by the controller and reduce the possible overshoot. Based on the first deviation value, the first adaptive controller combines the fuzzy rules to generate the adjustment control parameters of the first heating device. The first deviation value is input into the first adaptive controller through the fuzzy rules for calculation to obtain the adjustment control parameters, which are the adjustment coefficients for the temperature parameters of the first heating device. And the adjustment control parameters are optimized based on the whale optimization algorithm. According to the whale optimization algorithm, the adjustment control parameters are optimized in the optimization space until the preset number of iterations. When the optimization iteration ends, the optimized adjustment control parameters are obtained. The first heating device adjusts the temperature during the preheating process based on the optimized adjustment control parameters. During the preheating process, the temperature deviation value is continuously detected to adjust the temperature through the first adaptive controller until the preheating process ends, so that the first heating device can correct the deviation in time, and then the preheated metal sheets are transported to the rolling device.

[0025] Specifically, based on the viscoelastic models and material parameters of the preheated metal sheets and in combination with a preset desired laminate thickness, control parameters of the rolling device are determined.
