Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0030] A straightener is a device used to straighten the shape of metal sheets. It eliminates the stress inside the metal sheet through mechanical force to make it straight. At present, the straightener straightens the metal sheet by the operator manually inputting the straightening parameters. However, this relies on the operator's experience and requires a high level of technical skills. In addition, it is difficult for the operator to deal with different defects of the metal sheet. The intelligence level of metal sheet straightening is not high, which makes the straightening efficiency low.

[0031] In order to solve the problems of the prior art, the embodiments of the present application provide a steel plate straightening method, device, system, equipment, storage medium and program product. The steel plate straightening system provided in the embodiments of the present application is first introduced below.

[0032] Figure 1 FIG. 1 shows an architecture diagram of a steel plate straightening system provided by an embodiment of the present application. Figure 1 As shown, the steel plate straightening system 100 may include:

[0033] A straightening machine 101, the straightening machine is used to straighten the i-th steel plate according to the target straightening parameter, i is a positive integer;

[0034] A first straightness meter 102, which is disposed at the entrance of the straightening machine and is used to collect first straightness information of the i-th steel plate, where the first straightness information is the straightness information of the i-th steel plate before straightening;

[0035] The upper computer 103 is communicatively connected with the first straightness meter 102 and the straightening machine 101, and is used for obtaining the initial straightening parameters and the first straightness information of the ith steel plate; identifying the target defect type of the ith steel plate according to the first straightness information; adjusting the initial straightening parameters according to the target adjustment strategy to obtain the target straightening parameters of the ith steel plate, wherein the target adjustment strategy is an adjustment strategy corresponding to the target defect type among multiple adjustment strategies, and different defect types correspond to different adjustment strategies; and sending the target straightening parameters to the straightening machine.

[0036] The above-mentioned straightening machine is a device used to straighten the shape of materials such as metal plates, strips, and bars, and eliminates the stress inside the material through mechanical force to make it straight. In the embodiment of the present application, the straightening machine can be a straightening machine with a programmable logic controller (PLC) to achieve precise control of the straightening process.

[0037] Straightening parameters refer to the various settings used by the straightening machine to control and adjust the straightening process. These parameters directly affect the straightening effect and the quality of the steel plate. Straightening parameters can include straightening roller spacing, straightening roller pressure, straightening roller inclination and straightening speed. Among them, straightening roller spacing: the distance between the upper and lower straightening rollers, affects the size and distribution of the straightening force. Straightening roller pressure: the pressure applied by the straightening roller on the steel plate determines the degree of deformation of the steel plate. Straightening roller inclination: the inclination angle of the straightening roller, used to adjust the force distribution of the steel plate. Straightening speed: the speed at which the steel plate passes through the straightening machine, affecting the straightening time and effect.

[0038] Steel plates with different steel plate information (such as steel type, specification and steel plate number) correspond to different straightening parameters. The material hardness and elastic modulus of different steel types are different. The higher the hardness, the greater the required straightening force; the elastic modulus affects the rebound characteristics of the steel plate. The larger the elastic modulus, the more obvious the rebound, and a greater straightening force or more straightening passes are required. The specifications of the steel plate include thickness, width and length. The thickness of the steel plate directly affects the setting of the spacing and pressure of the straightening rollers. The greater the thickness, the greater the straightening force required, and the roller spacing needs to be adjusted accordingly; the width of the steel plate affects the force distribution of the straightening rollers. The greater the width, the more uniform the pressure distribution of the straightening rollers needs to be; the length of the steel plate affects the straightening speed and pass setting. Longer steel plates may require segmented straightening. Different batches of the same steel type may have slight differences (such as composition fluctuations, internal stress distribution, etc.), and the straightening parameters need to be determined according to the steel plate number.

[0039] The first straightness meter is a precision instrument for measuring the surface straightness of a steel plate, which can be arranged at the entrance of a straightening machine to collect the straightness information of the steel plate before straightening.

[0040] The above-mentioned host computer may refer to a computer system used to monitor, manage and control the lower computer in industrial automation and control systems. The host computer is connected to the first straightness meter and the straightener in communication. Exemplarily, the communication connection method may include wired communication (such as RS232, RS485, Ethernet, fieldbus) and wireless communication (such as Wi-Fi, Bluetooth, ZigBee, 4G / 5G). Communication protocols (such as Modbus, Profibus, OPC, TCP / IP, MQTT) are the key to achieving data exchange. Selecting appropriate communication connection methods and communication protocols according to actual needs can ensure the stability, real-time and scalability of the steel plate straightening system.

[0041] In some embodiments, the system 100 may further include:

[0042] A second straightness meter 104 is provided at the exit of the straightening machine and is used to collect second straightness information of the i-th steel plate. The second straightness information is the straightness information of the i-th steel plate after being straightened. The second straightness information includes maximum deviation, average deviation, straightness curve characteristics and three-dimensional topography characteristics.

[0043] The above-mentioned host computer 103 is communicatively connected with the second flatness meter 104, and is also used to determine that the i-th steel plate is a qualified steel plate when the maximum deviation is less than or equal to the preset first deviation threshold, the average deviation is less than or equal to the preset second deviation threshold, the flatness curve feature characterizes that the flatness curve is smooth, and the three-dimensional morphology feature characterizes that the surface of the three-dimensional morphology is flat.

[0044] The second straightness meter can be arranged at the exit of the straightening machine to collect the straightness information of the steel plate after being straightened.

[0045] The host computer can also be connected to the second straightness meter for communication. The communication connection mode and communication protocol can refer to the example of communication connection between the host computer and the first straightness meter and the straightening machine, which will not be repeated here.

[0046] Figure 2 The schematic diagram of the process of a steel plate straightening method provided by an embodiment of the present application is shown. Optionally, the method of the embodiment of the present application can be applied to the above Figure 1 The steel plate straightening system 100 is shown. Figure 2 As shown, a steel plate straightening method is applied to a host computer, and the method may include the following steps S201 to S204:

[0047] S201, obtaining initial straightening parameters and first straightness information of the i-th steel plate, where the first straightness information is the straightness information of the i-th steel plate before straightening, and i is a positive integer;

[0048] S202, identifying a target defect type of the i-th steel plate according to the first flatness information;

[0049] S203, adjusting the initial straightening parameters according to the target adjustment strategy to obtain the target straightening parameters of the i-th steel plate, where the target adjustment strategy is an adjustment strategy corresponding to the target defect type among multiple adjustment strategies, and different defect types correspond to different adjustment strategies;

[0050] S204. Send the target straightening parameters to the straightening machine, so that the straightening machine straightens the i-th steel plate according to the target straightening parameters.

[0051] In the steel plate straightening method of the embodiment of the present application, the host computer can obtain the initial straightening parameters and the first straightness information of the i-th steel plate, the first straightness information is the straightness information of the i-th steel plate when it is not straightened, and i is a positive integer; and according to the first straightness information, the target defect type of the i-th steel plate is identified; then the initial straightening parameters are adjusted according to the target adjustment strategy to obtain the target straightening parameters of the i-th steel plate, the target adjustment strategy is an adjustment strategy corresponding to the target defect type among multiple adjustment strategies, and different defect types correspond to different adjustment strategies; finally, the target straightening parameters are sent to the straightening machine, so that the straightening machine straightens the i-th steel plate according to the target straightening parameters. In this way, in the embodiment of the present application, the target defect type of the i-th steel plate can be identified by the first straightness information of the i-th steel plate when it is not straightened, and the initial straightening parameters are adjusted according to the target adjustment strategy corresponding to the target defect type, so that the straightening machine straightens the i-th steel plate according to the target straightening parameters, so as to meet the straightening requirements of different defects of the metal plate, thereby improving the intelligence of the metal plate straightening, and then improving the straightening efficiency.

[0052] In S201, the first flatness information is the flatness information of the i-th steel plate when it is not straightened, and i is a positive integer. The first flatness information may include a flatness curve feature and a three-dimensional topography feature. The flatness curve feature may show the deviation of the steel plate surface from the ideal plane, and may be used to characterize whether the flatness curve is smooth. The three-dimensional topography feature may intuitively show the shape and deformation of the steel plate surface, and may be used to characterize whether the three-dimensional topography surface is flat.

[0053] The above-mentioned initial straightening parameters of the i-th steel plate can be obtained, for example, the initial straightening parameters input by the operator in the upper computer based on experience according to the steel plate information, or the steel plate information can be input into a preset straightening model, and the initial straightening parameters of the i-th steel plate are obtained by output. The straightening model is trained based on multiple historical steel plate information and the historical straightening parameters corresponding to each historical steel plate information.

[0054] In S202, the target defect type may be a defect type corresponding to the first flatness information among multiple defect types.

[0055] According to the first flatness information, the target defect type of the i-th steel plate is identified. For example, the target defect type of the i-th steel plate can be identified according to the flatness curve feature or the three-dimensional topography feature. The correspondence between the flatness curve feature, the three-dimensional topography feature and the multiple defect types is shown in Table 1 below. It should be noted that the multiple defect types can include not only the examples in Table 1 below, but also other defect types, which are not specifically limited here.

[0056] Table 1:

[0057]

[0058]

[0059] In S203, the above-mentioned target adjustment strategy is an adjustment strategy corresponding to the target defect type among multiple adjustment strategies, and different defect types correspond to different adjustment strategies. Exemplarily, the adjustment strategy for the wavy edge: the straightening roller spacing reduces the roller spacing in the edge area to increase the straightening force on the edge; the straightening roller pressure increases the straightening roller pressure in the edge area; the straightening roller inclination adjusts the inclination of the straightening roller to make the force in the edge area more uniform; the straightening speed reduces the straightening speed to ensure that the edge area is fully straightened. The adjustment strategy for the middle wave: the straightening roller spacing reduces the roller spacing in the middle area to increase the straightening force on the middle; the straightening roller pressure increases the straightening roller pressure in the middle area; the straightening roller inclination adjusts the inclination of the straightening roller to make the force in the middle area more uniform; the straightening speed reduces the straightening speed to ensure that the middle area is fully straightened. Adjustment strategy for single-sided waves: Reduce the roller spacing on the wave side to increase the straightening force; increase the straightening roller pressure on the wave side; adjust the straightening roller inclination to make the wave side more evenly stressed; reduce the straightening speed to ensure full straightening of the wave side. Adjustment strategy for warping: Adjust the roller spacing evenly to ensure uniform overall stress; increase the straightening roller pressure to eliminate lateral bending; adjust the straightening roller inclination to make the steel plate more evenly stressed; reduce the straightening speed appropriately to ensure full straightening. Adjustment strategy for sickle bends: Reduce the roller spacing in the bending area to increase the straightening force; increase the straightening roller pressure on the bending area; adjust the straightening roller inclination to make the bending area more evenly stressed; reduce the straightening speed to ensure full straightening of the bending area. Local concave and convex adjustment strategy: the straightening roller spacing in the concave and convex area is reduced to increase the straightening force; the straightening roller pressure increases the straightening roller pressure in the concave and convex area; the straightening roller inclination adjusts the inclination of the straightening roller to make the force in the concave and convex area more uniform; the straightening speed reduces the straightening speed to ensure that the concave and convex area is fully straightened. Transverse bending adjustment strategy: the straightening roller spacing is evenly adjusted to ensure uniform overall force; the straightening roller pressure increases the overall straightening roller pressure to eliminate transverse bending; the straightening roller inclination adjusts the inclination of the straightening roller to make the steel plate more uniformly stressed; the straightening speed appropriately reduces the straightening speed to ensure full overall straightening. Longitudinal bending adjustment strategy: the straightening roller spacing in the bending area is reduced to increase the straightening force; the straightening roller pressure increases the straightening roller pressure in the bending area; the straightening roller inclination adjusts the inclination of the straightening roller to make the force in the bending area more uniform; the straightening speed reduces the straightening speed to ensure full straightening in the bending area. Distortion adjustment strategy: straightening roller spacing evenly adjusts the roller spacing to ensure uniform overall force; straightening roller pressure increases the overall straightening roller pressure to eliminate distortion; straightening roller inclination adjusts the inclination of the straightening roller to make the steel plate more evenly stressed; straightening speed appropriately reduces the straightening speed to ensure full overall straightening.Local warping adjustment strategy: straightening roller spacing: reduce the roller spacing in the warping area to increase the straightening force; straightening roller pressure: increase the straightening roller pressure in the warping area; straightening roller inclination: adjust the inclination of the straightening roller to make the force in the warping area more uniform; straightening speed: reduce the straightening speed to ensure that the warping area is fully straightened.

[0060] In S204, the target straightening parameters are sent to the straightening machine. For example, the host computer may send the target straightening parameters to the PLC of the straightening machine through wired communication, so that the PLC controls each encoder of the straightening machine to straighten the i-th steel plate according to the target straightening parameters.

[0061] In some embodiments, the above S201 may specifically include:

[0062] Get the steel plate information of the i-th steel plate, the steel plate information includes steel type, specification and steel plate number;

[0063] The steel plate information is input into a preset straightening model, and the initial straightening parameters of the i-th steel plate are output. The straightening model is trained based on multiple historical steel plate information and historical straightening parameters corresponding to each historical steel plate information.

[0064] The above-mentioned steel plate information may include steel type, specification and steel plate number. Among them, different steel types have different hardness (such as low carbon steel, high strength steel, stainless steel, etc.). The higher the hardness, the greater the straightening force required. The greater the thickness, the greater the straightening force required, and the roller spacing needs to be adjusted accordingly; the greater the width, the more uniform the pressure distribution of the straightening rollers needs to be; longer steel plates may require segmented straightening. Different batches of the same steel type may have slight differences (such as composition fluctuations, internal stress distribution, etc.), and the straightening parameters need to be determined according to the steel plate number.

[0065] The above straightening model is trained based on a plurality of historical steel plate information and historical straightening parameters corresponding to each historical steel plate information.

[0066] In an embodiment of the present application, the steel plate information includes steel type, specification and steel plate number, and the straightening model is trained by multiple historical steel plate information and historical straightening parameters corresponding to each historical steel plate information. Therefore, by inputting the steel plate information of the i-th steel plate into the preset straightening model, the initial straightening parameters of the i-th steel plate can be accurately obtained, thereby reducing the high requirements on the operator's technical level.

[0067] As an implementation of the present application, in order to accurately identify whether the steel plate is qualified, after the above S204, the above method may further include:

[0068] Acquire second flatness information of the i-th steel plate, the second flatness information is the flatness information of the i-th steel plate after being straightened, and the second flatness information includes maximum deviation, average deviation, flatness curve characteristics and three-dimensional topography characteristics;

[0069] When the maximum deviation is less than or equal to a preset first deviation threshold, the average deviation is less than or equal to a preset second deviation threshold, the flatness curve feature characterizes that the flatness curve is smooth, and the three-dimensional morphology feature characterizes that the surface of the three-dimensional morphology is flat, the i-th steel plate is determined to be a qualified steel plate.

[0070] The second flatness information may include maximum deviation, average deviation, flatness curve characteristics and three-dimensional topography characteristics. The maximum deviation refers to the vertical distance between the highest point and the lowest point on the steel plate surface. The average deviation refers to the average value of the deviations of each point on the steel plate surface.

[0071] In the above-mentioned case where the maximum deviation is less than or equal to the preset first deviation threshold, the average deviation is less than or equal to the preset second deviation threshold, the flatness curve characteristic characterizes that the flatness curve is smooth, and the three-dimensional morphology map characteristic characterizes that the surface of the three-dimensional morphology map is flat, the i-th steel plate is determined to be a qualified steel plate. Exemplarily, the maximum deviation of the i-th steel plate may be 1.5mm / m≤the first deviation threshold 2mm / m, the average deviation is 0.8mm / m≤the second deviation threshold 1mm / m, the straightness curve characteristic characterizes that the flatness curve is smooth without obvious fluctuations, and the three-dimensional morphology map characteristic characterizes that the three-dimensional morphology map shows that the surface is flat without local bumps and depressions, then the i-th steel plate is determined to be a qualified steel plate.

[0072] In some embodiments, when the maximum deviation in the second flatness information is greater than the first deviation threshold, the average deviation is greater than the second deviation threshold, the flatness curve characteristic indicates that the flatness curve is not smooth, or the three-dimensional topography characteristic indicates that the surface of the three-dimensional topography is not flat, the steel plate is determined to be an unqualified steel plate and the straightening process is performed again. For example, the maximum deviation may be 3.0 mm / m>2 mm / m, or the average deviation may be 1.2 mm / m greater than 1 mm / m, or the flatness curve characteristic indicates that the flatness curve shows obvious periodic fluctuations (wavy edges), or the three-dimensional topography characteristic indicates that the three-dimensional topography shows unevenness in a local area, then the i-th steel plate is determined to be an unqualified steel plate.

[0073] In an embodiment of the present application, after the straightening machine straightens the i-th steel plate according to the target straightening parameters, the maximum deviation, average deviation, straightness curve characteristics and three-dimensional morphology characteristics in the second straightness information of the i-th steel plate after straightening are used to accurately identify whether the steel plate is qualified.

[0074] As another implementation of the present application, in order to further improve the straightening efficiency of the steel plate, after determining that the i-th steel plate is a qualified steel plate, the method may further include:

[0075] The target straightening parameters are determined as the initial straightening parameters of the same steel plate, where the same steel plate is a steel plate having the same steel plate information as the i-th steel plate.

[0076] The above-mentioned same steel plate is a steel plate having the same steel plate information as the i-th steel plate.

[0077] In an embodiment of the present application, after determining that the i-th steel plate is a qualified steel plate, the target straightening parameters are also determined as the initial straightening parameters of the same steel plate, so that they can be directly called when the same steel plate is subsequently straightened, thereby improving the response speed of the straightening system and further improving the straightening efficiency of the steel plate.

[0078] In order to facilitate the understanding of the steel plate straightening method in the embodiment of the present application, the actual application process of the steel plate straightening method is described as follows:

[0079] like Figure 3 As shown, in the embodiment of the present application, a straightness meter 1 (equivalent to the first straightness meter mentioned above) is arranged in front of the straightening machine to collect the unevenness information of the incoming material, and send the information (equivalent to the first straightness information mentioned above) to the host computer, so that the host computer can make targeted parameter adjustments. At the same time, a straightness meter 2 (equivalent to the second straightness meter mentioned above) is arranged behind the straightening machine to also collect the unevenness information of the steel plate after straightening (equivalent to the second straightness information mentioned above) and feed it back to the host computer. If the steel plate is qualified, no adjustment will be made and the parameters (equivalent to the target straightening parameters) will be stored. If it is unqualified, the adjustment will continue. The specific operation logic is:

[0080] 1. When the steel plate arrives at the front roller of the straightening machine, the production management system sends the steel plate information (steel type, specification, steel plate number) to the straightening machine model in the upper computer (i.e. the above-mentioned straightening model). The straightening machine model calculates the parameters (equivalent to the above-mentioned initial straightening parameters) according to the steel plate information, and feeds the parameters back to the controller of the straightening machine. The controller controls each encoder to perform the action;

[0081] 2. The straightness meter 1 scans the straightness of the steel plate and transmits the information to the straightening machine model. The straightening machine model judgment module identifies the defect type (equivalent to the above-mentioned target defect type) based on the steel plate straightness information and determines whether it is necessary to increase the compensation value or adjust the bending roller;

[0082] 3. When the steel plate enters the straightening machine for straightening, the straightening machine storage module stores the straightening parameters under the current specifications and corresponding raw material plate shape, which is convenient for the next call;

[0083] 4. After the steel plate leaves the straightening machine, it passes through the straightness meter 2, which scans the straightness of the steel plate and transmits the information to the straightening model of the straightening machine;

[0084] 5. The judgment module judges whether the straightness meets the delivery requirements. If it does, the storage module stores the straightening parameters of the current specifications and the corresponding raw material plate shape to facilitate the next call; if it does not meet the delivery requirements, it cannot be shipped or must be handled separately.

[0085] In the embodiment of the present application, compared with the traditional straightening production line, an additional straightness meter is added in front of the straightening machine as the visual system of the straightening machine, which can realize true intelligent plate shape control without human intervention; the autonomous calculation, storage and update of the straightening model are realized, and through the addition of the visual system and the judgment system, the straightening parameters can be continuously adjusted in production, feedback can be obtained, and the storage can be updated in real time; it will greatly reduce the labor production cost and improve the straightening efficiency and the qualified rate.

[0086] Based on the steel plate straightening method provided in the above embodiment, the present application also provides a specific implementation of a steel plate straightening device. Please refer to the following embodiment.

[0087] like Figure 4 As shown, the steel plate straightening device 400 provided in the embodiment of the present application is applied to a host computer, and the device 400 may include the following modules: a first acquisition module 401, an identification module 402, an adjustment module 403 and a sending module 404.

[0088] A first acquisition module 401 is used to acquire initial straightening parameters and first straightness information of the i-th steel plate, where the first straightness information is the straightness information of the i-th steel plate before straightening, and i is a positive integer;

[0089] An identification module 402 is used to identify a target defect type of the i-th steel plate according to the first flatness information;
