[0011] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0012] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or modules that are not clearly listed or inherent to these processes, methods, products, or devices.

[0013] Embodiment 1 like Figure 1 As shown, the present application provides a stamping forming machine processing method for an aluminum foil lunch box, the method comprising: P10: Determine the machining process based on the production specifications of the batch of aluminum foil lunch boxes; Specifically, the production specifications of the current batch of aluminum foil lunch boxes are obtained, including the geometric shape, alloy state, thickness, size, etc. of the aluminum foil lunch boxes, and based on the production specifications, the machining process of the current batch of aluminum foil lunch boxes is determined. The machining process refers to the mechanical processing production process of the aluminum foil lunch boxes, including aluminum foil material preparation, material hardening treatment, cutting, forming, demolding, cooling, trimming, cleaning, quality inspection and other processes, which can be used as reference data for subsequent process node segmentation.

[0014] P20: Segment the process nodes for the machining process to generate a target control link, wherein each link node is marked with a synchronous braking parameter; It should be understood that, according to the processing procedures, the machining process is divided into process nodes to obtain a plurality of divided process nodes, and the plurality of divided process nodes are arranged in sequence to generate a target control link, wherein the target control link has a plurality of link nodes corresponding to the plurality of divided process nodes, and each link node is marked with a synchronous braking parameter, and the synchronous braking parameter refers to a parameter for braking at the same time, such as when feeding, the feeding robot arm and the feed port are braked at the same time. The target control link can be used to relatively regulate the various process nodes of the production process, and by optimizing the synchronous braking parameters of each node, the accuracy of the data exchanged between the various process links can be improved to achieve the purpose of optimizing the overall process flow.

[0015] Furthermore, step P20 of the embodiment of the present application further includes: P21: Retrieve pre-processing control parameters, i.e. pre-set hard processing control parameters; P22: Segment the machining process node by node, sequentially connect the segmented nodes, and generate the target control link; P23: traverse the target control link, perform synchronization mapping and timing control segmentation with the hard processing control parameters, and obtain the synchronous braking parameters corresponding to each link node.

[0016] Among them, the pre-processing control parameters of the machining process are retrieved, and the pre-processing control parameters are hard processing control parameters pre-set according to the production specifications of the current batch of aluminum foil lunch boxes and production experience values, such as punching force, punching frequency, etc. Further, the process nodes of the machining process are segmented one by one to obtain multiple segmentation nodes, and the multiple segmentation nodes are connected in the order of the machining process to generate the target control link. Finally, the various link nodes of the target control link are traversed, the corresponding hard processing control parameters are matched for each link node, and the control parameters are segmented according to the order of control time to obtain the synchronous braking parameters corresponding to each link node.

[0017] P30: Based on the target control link, calling the first link node and combining the identified synchronous braking parameters to perform machining control and obtain first control data; Optionally, a link node is randomly called from the target control link as the first link node, and mechanical processing control is performed in combination with the synchronous braking parameters corresponding to the first link node, and the actual change values ​​of each braking parameter in the processing control process are extracted, such as measuring the actual punching force of the pressurizing equipment during the pressurizing process, the actual moving distance during the feeding process, etc., which are used as the first control data. The first control data is the actual parameter response value of the equipment, which can be compared with the expected parameter change value to determine the accuracy of the control parameters of the stamping equipment, thereby eliminating equipment errors.

[0018] P40: for the first control data, a node control evaluation is performed in combination with a link control analysis module to obtain a first evaluation feature, wherein the link control analysis module is embedded with an evaluation standard corresponding to each link node under a standard processing state, and each evaluation standard has a tolerance interval; Exemplarily, for the first control data, a link control analysis module is used to evaluate the node control thereof to obtain a first evaluation feature. The link control analysis module is a module used to evaluate the accuracy of the control data of each link node of the stamping equipment, which has embedded evaluation standards for each link node under a standard processing state. The evaluation standard refers to the standard transformation value of each control parameter under a standard working state. For example, when the pressurization instruction is 40 tons, the actual pressurization value of the pressurization equipment should also be 40 tons. Each evaluation standard has a tolerance interval, which refers to the allowable range of control parameter errors. The first evaluation feature refers to the actual control data evaluation result of the first link node, including pressure control evaluation results, displacement control evaluation results, etc., which can reflect the accuracy of the control data of the first link.

[0019] Further, such as Figure 2 As shown, step P40 of the embodiment of the present application also includes: P41: For the multivariate control components of the stamping machine, the degree of freedom of machining is evaluated to determine the degree of freedom coefficient; P42: Evaluate the eccentricity angle and eccentricity size for the control energy efficiency of aluminum foil materials and determine the eccentricity coefficient; P43: Evaluate the sheet flow velocity and radial tensile stress of the stamping die and aluminum foil material to generate the stamping control coefficient; P44: Traverse the target control link, map and associate each link node with the evaluation index to determine multiple association sequences, and build the link control analysis module.

[0020] Among them, the degree of freedom of machining is evaluated for the multi-control components of the stamping machine. The stamping machine is a mechanical processing device used to stamp and form aluminum foil lunch boxes, and includes multiple stamping control components, that is, multi-control components, such as pressurizing components, transmission components, etc. For the multi-control components of the stamping machine, that is, for the control dimensions of each link node, adaptive evaluation and analysis of multiple dimensions are performed, including the degree of freedom dimension, the material eccentricity dimension, and the stamping control dimension.

[0021] First, the degree of freedom of machining of each component is evaluated. The degree of freedom refers to the parameter adjustment range of each component. By evaluating the degree of freedom of the corresponding actual control data, the difference between the actual degree of freedom of each component and the standard degree of freedom is determined, and the corresponding degree of freedom coefficient is generated according to the size of the difference value. For example, the larger the difference value, the larger the corresponding degree of freedom coefficient. By analogy, the eccentric angle and eccentric size are evaluated for the control energy efficiency of the aluminum foil material, that is, the deviation between the actual moving position of the material and the standard moving position is calculated, and the eccentricity coefficient is generated. Further, for the stamping die set and the aluminum foil material, the sheet flow velocity and radial tensile stress are evaluated to determine whether the sheet flow velocity matches the radial tensile stress and whether the desired sheet flow velocity and sheet size are achieved, and thus the stamping control coefficient is generated.

[0022] Furthermore, each link node of the target control link is traversed, each link is mapped and associated with a corresponding evaluation index, a plurality of association sequences are obtained, and the link control analysis module is built based on the plurality of association sequences.

[0023] Furthermore, step P41 of the embodiment of the present application further includes: P41-1: The multi-control component includes a pressure component, a feeding component and a guide component; A three-dimensional coordinate system is constructed with the single degrees of freedom of the pressure component, the feeding component and the guide component as coordinate axes; P41-2: Based on the link node to be analyzed, determine at least one single degree of freedom threshold, and set a degree of freedom analysis constraint in the three-dimensional coordinate system, wherein the degree of freedom analysis constraint has link node update properties.

[0024] It should be understood that the multi-control component includes a pressure component, a feeding component and a guide component. The pressure component is mainly used to pressurize the product to form it, the feeding component is mainly used to convey the aluminum foil material, the guide component is a component used for direction control, and related transmission components. Further, a three-dimensional coordinate system is constructed with the single degrees of freedom of the pressure component, the feeding component and the guide component as coordinate axes. The single degree of freedom refers to the parameter adjustment range of each component, such as the adjustment range of the punching force.

[0025] Furthermore, for each of the multiple link nodes to be analyzed, at least one single degree of freedom threshold is determined, that is, a single degree of freedom threshold is determined based on each link node, and the single degree of freedom threshold can be understood as a standard value of the degree of freedom, wherein the single degree of freedom thresholds of multiple link nodes overlap. Furthermore, for different link nodes, the single degree of freedom threshold is used to set multiple degree of freedom analysis constraints in the three-dimensional coordinate system, that is, multiple standardized coordinate points. The degree of freedom analysis constraints have link node update properties, which means that different link nodes have different degree of freedom analysis constraints, which can be used to perform degree of freedom evaluations on different link nodes. Subsequently, coordinate systems of different dimensions can be built for each evaluation dimension, and node regulation analysis can be performed based on the differentiation between standardized coordinate points and actual operation coordinate points.

[0026] P50: If the first evaluation feature is different, adjust the synchronous braking parameter of the second link node in combination with the braking calibration module to obtain a calibrated braking parameter, wherein there is a communication connection with the braking calibration module; In a possible embodiment of the present application, if there is an abnormality in the first evaluation feature, that is, there is a deviation in the processing control result of the first link node, the synchronous braking parameters of the second link node are adjusted through the braking calibration module, that is, the braking parameters of the next node of the first link node are adjusted, and the calibrated braking parameters are obtained, that is, the synchronous braking parameters of the second link node after considering the processing control error of the first link node. The braking calibration module is a module used to adjust and optimize the synchronous braking parameters of the downstream link through the control evaluation results of the upstream link node. The deviation of the processing control result of the first link node can be compensated by the calibrated braking parameters of the second link node, thereby improving the overall control accuracy and product quality.

[0027] Further, such as Figure 3 As shown, step P50 of the embodiment of the present application also includes: P51: transferring the first evaluation feature flow to the brake calibration module, and calling the synchronous braking parameter of the second link node; P52: Determine a calibration scheme based on the first evaluation feature, calibrate the synchronous braking parameter of the second link node, and obtain the calibrated braking parameter; P53: Among them, the braking calibration module includes a differentiation identification layer, a solution decision layer and a parameter calibration layer. The calibrated braking parameters are single-executionable. After the machining control of the second link node is completed, the calibrated braking parameters are controlled and reset.

[0028] Among them, the first evaluation feature data is input into the braking calibration module, and the synchronous braking parameters of the second link node are called, and then the error between the first evaluation feature and the standard control data is calculated, and then the calibration scheme is determined. Furthermore, the braking calibration module calibrates the synchronous braking parameters of the second link node through the calibration scheme to obtain the calibrated braking parameters.

[0029] Furthermore, the braking calibration module includes a differentiation recognition layer, a scheme decision layer and a parameter calibration layer. The differentiation recognition layer is used to identify the feature differences between actual evaluation features and standard evaluation features. The scheme decision layer is used to decide the calibration scheme through feature differences. The parameter calibration layer is used to calibrate the braking parameters of the next link node through the calibration scheme, and the calibrated braking parameters are single-executionable, that is, after completing the machining control of the second link node, the synchronization control parameters of the second link node need to be reset in preparation for the next machining.

[0030] P60: Traverse the target control link, perform control evaluation of upper link nodes and control optimization of lower link nodes link by link node, and realize adaptive flexible processing control.

[0031] Optionally, all link nodes of the target control link are traversed, and the processing state control evaluation of the upper link nodes is performed on all link nodes one by one to extract the control error of each link node, and the control error of the upper node is eliminated by controlling and optimizing the synchronous braking parameters of the lower link nodes, thereby realizing adaptive flexible processing regulation of the stamping forming machine for aluminum foil lunch boxes, reducing the production errors of each processing link, and improving the overall processing accuracy and product quality.

[0032] Furthermore, the embodiment of the present application further includes step P70, and step P70 further includes: P71: Execute processing monitoring of the stamping machine and determine a processing control state, wherein the processing control state includes switching between hard processing control and flexible processing control; P72a: Based on the processing control state, the frequency statistics of the flexible processing control are performed to calculate and obtain the flexibility ratio; P73a: If the flexibility ratio meets the threshold standard, activate the emergency control module and perform operation and maintenance regulation of the stamping machine.

[0033] In a possible embodiment of the present application, the processing state of the stamping machine is monitored to determine the processing state of the stamping machine at each process node. The processing control state includes a hard processing control state and a flexible processing control state. The hard processing control refers to a link node that performs processing control based on pre-set synchronous braking parameters. The flexible processing control is the adaptive flexible processing regulation of the present application. Furthermore, through the processing control state of each link node, the nodes that use flexible processing control are extracted, and the frequency of flexible processing control is statistically analyzed based on this, and then the frequency of flexible processing control is divided by the total number of processing nodes to obtain a flexible ratio, that is, the proportion of nodes using flexible processing control to the total number of nodes.

[0034] Furthermore, the flexibility ratio is compared with a preset flexibility ratio threshold value. The flexibility ratio threshold value is the maximum flexibility ratio value, which is set according to an empirical value, for example, 40%. When the flexibility ratio meets the threshold standard, that is, the flexibility ratio exceeds the flexibility ratio threshold value, it indicates that the overall control error of the current equipment is large, and the excessive proportion of flexible processing control will increase the processing cost. Therefore, it is necessary to activate the emergency control module. The emergency control module is a module used for emergency braking. The emergency control module issues equipment abnormality instructions, performs operation and maintenance on the stamping machine, calibrates equipment errors, improves equipment accuracy and product quality, and reduces processing costs.

[0035] Furthermore, step P70 of the embodiment of the present application further includes: P72b: Based on the processing control state, identifying and determining the neighborhood processing interval duration; P73b: Call multiple neighbor processing intervals within a predetermined time to build an interval trend curve, where the multiple neighbor processing intervals have a time sequence; P74b: Identify the interval trend curve, calibrate the interval control standard and determine whether there is an abnormal interval control feature; P75b: If present, activate the emergency control module and perform operation and maintenance control of the stamping machine.

[0036] Optionally, by extracting the processing control status of multiple different products, identifying and determining the processing interval durations of different products, setting a predetermined interception time, such as three months, and intercepting multiple neighborhood processing interval durations within the predetermined time, the multiple neighborhood processing interval durations are time-series, and using the multiple neighborhood processing interval durations to draw an interval trend curve, further, by identifying the interval duration change trend of the interval trend curve and comparing it with the interval control standard, it is determined whether there is an interval duration that exceeds the interval control standard, and then it is determined whether there is an abnormal interval control feature. If so, it means that the processing time error of the stamping machine is large and there may be equipment failure, then the emergency control module is activated and the operation and maintenance of the stamping machine is regulated.

[0037] In summary, the embodiments of the present application have at least the following technical effects: The present application divides the machining process of the aluminum foil lunch box into process nodes, generates a target control link, calls the first link node for machining control, and performs node control evaluation to obtain a first evaluation feature. If the first evaluation feature is different, error calibration is performed by calibrating the synchronous braking parameters of the second link node. Similarly, the target control link is traversed, and control evaluation of the upper link node and control optimization of the lower link node are performed link by link node to achieve adaptive flexible processing regulation.

[0038] The technical effect of improving processing accuracy and product quality by calibrating the processing equipment error of the stamping and forming machine of the aluminum foil lunch box is achieved.
