It has good mechanical properties, corrosion resistance and thermal conductivity, which can effectively improve the safety and overall quality of buildings.

[0003] However, because the surface of aluminum alloy formwork is susceptible to oxidation and corrosion, chemical treatment is necessary to improve its performance and appearance. Existing surface treatment methods for aluminum alloy formwork suffer from low precision control, failing to promptly adjust and optimize subsequent processes based on the current treatment status. This results in poor overall surface treatment quality, affecting the normal use of the aluminum alloy formwork.

[0004] The shortcomings of existing aluminum alloy template surface treatment methods are that the surface treatment quality is low due to the low precision of surface treatment process control. Summary of the Invention

[0009] This method addresses the technical problem of low surface treatment quality due to low precision in surface treatment process control in existing aluminum alloy template surface treatment methods. First, it acquires the user's aluminum alloy surface treatment requirements and analyzes these requirements to establish a requirement feature set for the aluminum alloy template.

Detailed Implementation

[0015] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0016] Based on the above description, as shown in Figure 1, this disclosure provides a surface treatment method for aluminum alloy templates based on chemical conversion, including:

[0017] Surface treatment of aluminum alloy templates refers to improving the performance requirements of aluminum alloy templates through chemical treatment and other methods, such as improving the appearance of aluminum alloy templates and enhancing their corrosion resistance. Common surface treatment methods for aluminum alloy templates include degreasing, etching, pickling, matte finishing, polishing, and chemical oxidation coating. The method provided in this application is used to optimize the surface treatment method of aluminum alloy templates based on chemical conversion, so as to improve the control precision and accuracy of aluminum alloy template surface treatment. The method is specifically implemented in a surface treatment system for aluminum alloy templates based on chemical conversion.

[0018] A requirement feature set for aluminum alloy templates is established, wherein the requirement feature set is obtained by parsing surface treatment requirements, and the surface treatment requirements are obtained by establishing user interaction.

[0019] In this embodiment, firstly, the target users' requirements for the aluminum alloy template are collected to obtain the surface treatment requirements. These surface treatment requirements can be set according to actual user needs, such as surface smoothness and corrosion resistance requirements. Then, the surface treatment requirements are analyzed for their characteristics. This analysis involves quantifying the index features of the surface treatment requirements, such as determining the surface finish index and corrosion resistance level of the aluminum alloy template, thus establishing a requirement feature set for the aluminum alloy template. By acquiring the user's surface treatment requirements and analyzing and constructing the requirement feature set, data support is provided for the next step of matching the control parameters of the aluminum alloy template, and the compatibility between the surface treatment control parameters and the user's surface treatment requirements can be improved.

[0020] A digital mapping of the processing capabilities of surface treatment processes is established. Using the set of required features as target features, theoretical fitting is performed based on the digital mapping to generate theoretical control parameters.

[0021] In this embodiment, firstly, multiple processing control parameters and corresponding processing capabilities of the surface treatment process are obtained. The processing capability refers to the surface state of the aluminum alloy after processing according to the processing control parameters. Using the processing capability as a sub-node and the corresponding processing control parameter as a leaf node, a digital mapping between the surface treatment process's processing capabilities and processing control parameters is established. Then, the required feature set is input as target features into the digital mapping for theoretical processing control parameter matching to obtain theoretical control parameters. These theoretical control parameters include surface treatment control parameters under multiple process timing nodes. Obtaining the theoretical control parameters provides data support for subsequent optimization and adjustment of the processing control parameters.

[0022] The surface treatment process is monitored in a steady state to generate a steady-state fluctuation space;

[0023] In this embodiment, firstly, historical surface treatment logs of the aluminum alloy template are retrieved, and historical surface treatment data is extracted based on these logs. This historical surface treatment data includes historical surface treatment control parameters and historical surface treatment results. Then, a steady-state analysis of the surface treatment process control parameters is performed based on the historical surface treatment data. This steady-state analysis refers to the stability analysis of the historical surface treatment results corresponding to the processing control parameters. Since the surface treatment results produced by the processing control parameters when surface treating the aluminum alloy template are not fixed, there will be differences; that is, the same processing control parameter may correspond to multiple surface treatment results. The range of surface treatment results corresponding to each processing control parameter and the probability of multiple surface treatment results within that range are determined. The range of surface treatment results includes all historical surface treatment results corresponding to the processing control parameter. A higher probability of a surface treatment result indicates higher stability of the surface treatment result obtained through the processing control parameter. Finally, a steady-state fluctuation space is constructed based on the range of surface treatment results corresponding to each processing control parameter and the probability of multiple surface treatment results within that range.

[0024] By constructing a steady-state fluctuation space, data support is provided for the next step of processing control parameter compensation and adjustment, which can improve the accuracy of processing control parameter compensation and adjustment.

[0025] A zero-point timing sequence is set, which is the raw material time node of the untreated aluminum alloy template. According to the time sequence node of the surface treatment process distribution, starting from the zero-point timing sequence, the surface image acquisition of the process time sequence node is executed sequentially to generate a time sequence image set.

[0026] In this embodiment, firstly, the raw material time node of the untreated aluminum alloy template is set as the zero-point time sequence, that is, the starting time node of the surface treatment of the aluminum alloy template is set to zero. Then, according to the time sequence nodes of the surface treatment process distribution, starting from the zero-point time sequence, surface images of the aluminum alloy template under the execution process time sequence nodes are acquired sequentially. That is, a surface image is acquired once after each process node is completed, and the surface image acquisition results are stored in the order of acquisition time to obtain a time sequence image set. By obtaining the time sequence image set, a basis is provided for comparing the surface treatment results under the process nodes.

[0027] The zero-point timing image is fitted with the theoretical control parameters to generate a monitoring image for the first process;

[0028] In this embodiment, firstly, a first theoretical control parameter is selected from the theoretical control parameters. This first theoretical control parameter is the surface processing control parameter at the first time-series node. Then, based on the first theoretical control parameter, simulated surface processing is performed on the zero-point time-series image to obtain a supervisory image after surface processing using the first theoretical control parameter, i.e., the supervisory image of the first process. The supervisory image represents the standard processed image of the zero-point time-series image after processing by the first process. The simulated surface processing method can utilize digital twin technology to simulate and model the surface processing process, constructing a surface processing simulation model, and performing simulated surface processing based on the simulation model. Obtaining the supervisory image of the first process provides support for the next step of surface processing image comparison.

[0029] The supervised image is used to call the mapped image of the time series image set, perform image comparison, and generate compensation parameters;

[0030] In this embodiment, firstly, the surface image acquisition results of the aluminum alloy template under the first process are retrieved from the time-series image set and marked as the first time-series image. Then, the supervised image is compared with the first time-series image, and the first surface treatment deviation is obtained based on the image comparison results. Then, compensation parameter analysis is performed based on the first surface treatment deviation to obtain the compensation parameters under the first process. The compensation parameter analysis method can be selected by those skilled in the art according to the actual situation. For example, a compensation parameter analysis model can be constructed based on a BP neural network, where the input data of the compensation parameter analysis model is the surface treatment deviation, and the output data is the compensation parameters of the surface treatment control parameters. Then, sample training data is extracted based on historical surface treatment data, and the compensation parameter analysis model is supervised and trained using the sample training data to obtain a compensation parameter analysis model that meets the expected indicators. Then, the first surface treatment deviation is analyzed using the trained compensation parameter analysis model to obtain the compensation parameters under the first process. By obtaining the compensation parameters under the first process, data support is provided for the next step of parameter compensation of the surface treatment control parameters.

[0031] By performing all parameter compensations on the time-series image set in a time-series order, the subsequent surface treatment management of the aluminum alloy template is completed based on the compensation results and the steady-state fluctuation space.

[0032] In this embodiment, all parameters of the time-series image set are compensated sequentially based on the time sequence, and the subsequent surface treatment process of the aluminum alloy template is controlled according to the compensation results and the steady-state fluctuation space. This method solves the technical problem of low surface treatment quality due to low precision in surface treatment process control in existing aluminum alloy template surface treatment methods. It allows for timely optimization and adjustment of the surface treatment control parameters of the aluminum alloy template, improving the precision and accuracy of surface treatment control, thereby enhancing the surface treatment quality of the aluminum alloy template.

[0033] In one embodiment, the method further includes:

[0034] Establish a spatial set of the raw material surface quality for aluminum alloy templates;

[0035] As shown in Figure 2, in one embodiment, the method further includes:

[0036] The aluminum alloy template is subjected to multi-dimensional feature detection of the raw material;

[0037] Obtain the impact value of unit change of each feature on the quality result, and use the impact value as the basic impact value;

[0038] Obtain the feature variation space of multidimensional features, evaluate the feature quality impact of each feature using the feature variation space and the basic impact value, and generate independent feature quality impact results.

[0039] The proportion of the quality influence results of the independent features is screened by using a quality influence threshold, and the main features and auxiliary features are determined based on the proportion screening results.

[0040] In this embodiment, a spatial set of raw material surface quality for the aluminum alloy template is established. First, multi-dimensional feature detection of the raw material is performed on the aluminum alloy template. These multi-dimensional features are those correlated with the surface treatment results of the raw material. Those skilled in the art can set these features according to the actual type of the raw material, such as surface finish. Then, the influence value of unit changes in each feature on the quality result is analyzed based on the multi-dimensional feature detection results. The greater the influence of unit changes in a feature on the quality result, the greater the influence value corresponding to that feature. This influence value is then used as the basic influence value of the feature.

[0041] A feature variation space for multidimensional features is obtained, where the feature variation space refers to the range of feature variations of the multidimensional features. Then, based on the feature variation space and the basic influence value, the feature quality influence of each feature is evaluated. That is, the feature quality influence is adjusted by the basic influence value through the feature variation space. The larger the feature variation space, the greater the upward adjustment of the basic influence value. The adjusted basic influence value is used as the independent feature quality influence result of the feature. The independent feature quality influence results of multiple features are obtained. The larger the independent feature quality influence result, the greater the influence of feature variation on the surface treatment result of aluminum alloy template.

[0042] A quality impact threshold is obtained, which can be set by those skilled in the art according to actual conditions. Then, the quality impact results of the independent features are filtered through the quality impact threshold. Features corresponding to the independent feature impact results greater than the quality impact threshold are marked as useful features, and features corresponding to the independent feature impact results less than or equal to the quality impact threshold are marked as useless features. Multiple useful features, i.e., proportional filtering results, are obtained. The influence ratio is determined according to the independent feature quality impact results of multiple useful features. The larger the independent feature quality impact result, the larger the influence ratio. Finally, the main feature and auxiliary features are determined according to the influence ratio of multiple useful features.

[0043] In one embodiment, the method further includes:

[0044] The ratio screening results are sorted in ratio order;

[0045] Based on the proportional difference, the difference between the first and second priority items is determined;

[0046] If the judgment passes, the first feature will be used as the primary feature, and the remaining features will be used as auxiliary features.

[0047] If the judgment fails, the difference between the second and third priority will be used to determine the difference based on the ratio difference.

[0048] If the determination passes, the first and second priority features will be used as the main features, and the remaining features will be used as auxiliary features.

[0049] If the judgment fails, the judgment iteration is performed, and the main feature and auxiliary feature are divided according to the iteration termination condition.

[0050] In this embodiment of the application, firstly, the useful features in the ratio screening results are sorted according to the influence ratio of the features, wherein the larger the influence ratio of the features, the higher the ranking of the useful features, thus obtaining a ratio order sequence.

[0051] Based on the aforementioned proportional order sequence, the first-ranked proportion is subtracted from the second-ranked proportion to obtain the proportional difference between the first and second ranks. A proportional difference threshold is obtained; this threshold can be set by those skilled in the art based on the actual degree of difference between useful features. Then, the proportional difference between the first and second ranks is judged according to the proportional difference threshold. When the proportional difference is greater than the threshold, the judgment is passed, indicating that the influence of the first-ranked useful feature is significantly greater than that of the second-ranked useful feature. In this case, the first-ranked useful feature is designated as the primary feature, and the remaining useful features are designated as auxiliary features. When the proportional difference is less than or equal to the threshold, the judgment is failed. The difference between the second and third ranks is then judged according to the threshold. When the judgment passes, the first and second-ranked useful features are designated as primary features, and the remaining features are designated as auxiliary features. When the judgment fails, the same method is used for iterative judgment until all useful features in the proportional screening result have been judged, thus completing the division of primary and auxiliary features in the proportional screening result.

[0052] By setting the main and auxiliary features according to the difference between useful features in the screening results, the accuracy of setting the main and auxiliary features can be improved, thereby improving the accuracy of setting the surface quality space set of the raw material.

[0053] A spatial set of the original surface quality of the aluminum alloy template is established based on the main features and the auxiliary features.

[0054] In this embodiment of the application, a spatial set of the raw material surface quality of the aluminum alloy template is constructed based on the main features and the auxiliary features. By obtaining the spatial set of the raw material surface quality, support is provided for the next step of analyzing the compensation results of surface control parameters.

[0055] Configure the control response accuracy of surface treatment, and use the control response accuracy as a segmentation reference to spatially segment the surface quality space set to generate a stepped reference value.

[0056] The corresponding raw material is called to perform surface treatment control based on the stepped reference value, and a mapping between the compensation result and the stepped reference value is established.

[0057] The subsequent surface treatment management of the aluminum alloy template is performed based on the mapping results and the steady-state fluctuation space.

[0058] In this embodiment, firstly, the control response precision of the surface treatment is configured. This precision is used to divide the surface treatment results under the first process. Those skilled in the art can set this precision according to actual needs; the higher the required precision, the higher the corresponding control response precision. Then, using the control response precision as the segmentation basis, the surface quality space set is spatially segmented. This involves extracting the surface treatment results corresponding to the control response precision from the surface quality space set. Different control response precisions correspond to different ranges of surface treatment results, resulting in a stepped reference value. This stepped reference value refers to the range of surface treatment results corresponding to the specified control response precision. Then, based on the stepped reference value, the corresponding raw material is called for surface treatment control, and a mapping between the compensation result and the stepped reference value is established. Finally, the subsequent surface treatment process of the aluminum alloy template is controlled based on the mapping result and the steady-state fluctuation space.

[0059] By generating stepped reference values ​​based on the control response accuracy of surface treatment, support is provided for obtaining supervisory images under the first process, which can improve the accuracy of supervisory image acquisition, thereby improving the accuracy of compensation parameter acquisition.

[0060] In one embodiment, the method further includes:

[0061] Read the surface quality of the raw aluminum alloy and use it as input data;

[0062] The input data is used to perform inter-step matching on the step reference value to obtain inter-step matching results;

[0063] The mapping result of the inter-step matching result is called, and the mapping result is adjusted proportionally according to the distribution of the input data in the inter-step. The surface treatment management of the current raw material is performed based on the proportional adjustment result.

[0064] In this embodiment, firstly, the surface quality of the raw aluminum alloy is read, and the surface quality of the raw aluminum alloy is used as input data to perform inter-step matching with the stepped reference value to obtain the inter-step matching result. The inter-step matching result refers to the range of multiple surface treatment results corresponding to multiple processes under the control response accuracy. The mapping result under the first process in the inter-step matching result is called, and the mapping result is adjusted proportionally according to the distribution of the input data between the steps, that is, the range of surface treatment results under the first process is determined, and the proportional adjustment result is obtained. Then, the supervision image corresponding to the proportional adjustment result is obtained, that is, the supervision image of the first process, and the surface treatment management of the current raw material is performed according to the supervision image of the first process.

[0065] In one embodiment, the method further includes:

[0066] The compensation result is identified using the steady-state fluctuation space.

[0067] If the compensation value meets the preset early warning threshold, a process early warning message will be generated.

[0068] The process control is maintained and managed through the aforementioned process early warning information.

[0069] In this embodiment, firstly, the compensation result is identified through the steady-state fluctuation space. Firstly, the compensation value corresponding to the compensation result is obtained, and then judged according to a preset warning threshold. The preset warning threshold can be set by those skilled in the art based on the steady-state fluctuation space. When the compensation value is greater than the preset warning threshold, it indicates that the compensation result exceeds the steady-state fluctuation space. Then, process warning information is generated, and the compensation value is corrected according to the process warning information, completing the maintenance and management of process control parameters. Correcting the compensation value by generating process warning information can improve the accuracy of the compensation value setting, thereby improving the accuracy of subsequent adjustments to the surface treatment control parameters of the aluminum alloy template.

[0070] In one embodiment, the method further includes:

[0071] Continuous evaluation of surface treatment results;

[0072] Bias defects are extracted by continuously processing evaluation results, and a mapping analysis is performed to correct these bias defects. Surface treatment compensation for the aluminum alloy template is then performed based on the results of the corrected mapping analysis.

[0073] In this embodiment, the surface treatment results are continuously evaluated according to the temporal sequence of the surface treatment processes, resulting in continuous evaluation results under multiple processes. A processing result evaluation threshold is set, which can be determined by those skilled in the art based on actual conditions. The continuous processing evaluation results are judged according to the threshold, and those results lower than the threshold are designated as biased defects. Then, the subsequent adjacent surface treatment processes are corrected based on these biased defects to obtain corrected mapping analysis results. Finally, the surface treatment processes of adjacent aluminum alloy templates are corrected and compensated based on the corrected mapping analysis results. By extracting biased defects from the continuous processing evaluation results and correcting and compensating the surface treatment processes of adjacent aluminum alloy templates based on these defects, the precision and accuracy of aluminum alloy template surface treatment control can be further improved.
