Description
Technical Field

[0002] In the lithium battery manufacturing process, the roll surface profile has a certain degree of curvature during the processing and use of the rolls, and this curvature plays a decisive role in the thickness quality of the rolled products.
[0003] In related technologies, rolling mill rolls undergo passive deformation during use to form a corresponding arc to compensate for deflection. This arc is typically formed by applying force or controlling temperature to change the arc shape of the roll surface. Furthermore, the required arc adjustment is extremely small, ranging from a few micrometers to tens of micrometers. These technologies rely on feedback from the quality of the rolled product for gradual arc adjustment. This method is difficult to quickly adapt to the diverse performance requirements of products, thus limiting the production efficiency of the electrode rolling process. Summary of the Invention

[0027] In related technologies, rolling mill rolls undergo passive deformation during use to form a corresponding arc to compensate for deflection. This arc is typically formed by applying force or controlling temperature to change the arc shape of the roll surface. Furthermore, the required arc adjustment is extremely small, ranging from a few micrometers to tens of micrometers. These technologies rely on feedback from the quality of the rolled product for gradual arc adjustment. This method is difficult to quickly adapt to the diverse performance requirements of products, thus limiting the production efficiency of the electrode rolling process.
[0028] To address the aforementioned issues, this application provides a roll detection device, adjustment method, and system that can quickly detect real-time roll surface attribute parameters and then dynamically adjust the roll surface curvature based on the real-time detected roll surface attribute parameters.
[0029] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0030] Figure 1 This is a schematic diagram of the overall structure of the roll inspection device shown in the embodiments of this application; Figure 2 This is an exploded view of the roll inspection device shown in the embodiments of this application.
[0031] See Figure 1 and Figure 2 This application provides a roll detection device 100, which includes a detection component, a moving mechanism 110, and a position adjustment system. The detection component is used to detect the roll surface attribute parameters of the roll 200. The moving mechanism 110 is connected to the detection component and is used to drive the detection component to move relative to the roll 200. The position adjustment system includes a first adjustment mechanism connected to the moving mechanism 110 and is used to adjust the spatial position of the moving mechanism 110 relative to the roll 200, so that the detection component detects the roll surface attribute parameters in the adjusted spatial position.
[0032] In this embodiment, the detection component includes a sensing element arranged facing the roll surface of the roll 200, and the detection axis of the sensing element forms a preset angle range with the normal of the roll surface of the roll 200. The sensing element includes at least one non-contact sensor, which is capable of detecting the roll surface attribute parameters of the roll 200 in a non-contact manner.
[0033] In some embodiments, the detection assembly includes a roll profile parameter detection element for detecting the curvature parameter of the roll surface; or, the detection assembly includes a temperature detection element for detecting the roll surface temperature; or, the detection assembly includes both a roll profile parameter detection element and a temperature detection element, which can simultaneously detect the curvature parameter of the roll surface and the roll surface temperature.
[0034] In some embodiments, the roller parameter detection element can be a distance sensor, such as a laser displacement sensor, and the temperature detection element can be an infrared temperature sensor.
[0035] The position adjustment system is used to actively correct the spatial position of the moving mechanism 110 or the detection component in at least two degrees of freedom through a mechanical fine-tuning structure. The moving mechanism 110 can drive the detection component to reciprocate along a preset direction, such as a direction parallel to the axis of the roll 200, thereby scanning the entire width or a specified section of the roll 200 axially. It can cooperate with the rotation of the roll to realize continuous measurement, fixed-point measurement, transverse measurement of the roll 200, and circumferential measurement of the roll 200.
[0036] The moving mechanism and the detection component are connected to the control system. After the control system obtains the roller surface attribute parameters detected by the detection component, it compares and analyzes the real-time measurement data with the target value, and outputs the force or temperature to the control unit to change the roller surface curvature, thus realizing closed-loop real-time online adjustment of the roller surface curvature.
[0037] The solution provided in this application can ensure that the detection component and the roll are always in the optimal relative position through the position adjustment system. Combined with the moving mechanism to drive the detection component to move along the preset direction of the roll, it can quickly detect the real-time roll surface attribute parameters. Then, it can dynamically adjust the roll surface curvature according to the real-time detected roll surface attribute parameters, thereby avoiding the defects of related technologies that can only rely on the quality feedback of the rolled product for gradual curvature adjustment, which makes it difficult to adapt to the diverse needs of product performance. This effectively improves the production efficiency of the electrode rolling process.
[0038] In some embodiments, a moving mechanism is used to drive the detection component to move axially relative to the roll; wherein the moving mechanism includes a translational transmission mechanism and a moving part driven by the translational transmission mechanism, and the detection component is mounted on the moving part; a first adjusting component is used to adjust the spatial position of the translational transmission mechanism relative to the roll so that the moving direction of the moving part is substantially parallel to the roll. Its function is to eliminate the tilt of the movement trajectory caused by installation errors or foundation deformation, thereby avoiding measurement deviations caused by the scanning path not being parallel to the roll axis during the measurement process.
[0039] See Figure 2 In some specific embodiments, the moving mechanism 110 includes a base 1101, a drive source 111, a translational transmission mechanism 112, and a moving component 114, wherein the detection component is mounted on the moving component 114. The drive source 111 is located on the base 1101, the translational transmission mechanism 112 is connected to the output end of the drive source 111, and the moving component 114 is driven to translate in conjunction with the translational transmission mechanism 112.
[0040] The drive source 111 can be a servo motor, the translation transmission mechanism 112 can be a combination of a lead screw and a guide rail 113, the output shaft of the drive source 111 is connected to the lead screw through a coupling, gear mechanism, belt transmission mechanism, etc., and the ball screw is fixed to the bottom of the moving part 114, so that the rotational motion of the drive source 111 is converted into the reciprocating translational motion of the moving part 114 along the linear direction.
[0041] The translation transmission mechanism 112 includes a pair of parallel linear guide rails 113 and a corresponding slider 114. The guide rails 113 are fixedly mounted on the base 1101 of the device in a direction parallel to the axis of the roll 200. The base 1101 can be made of marble or other stone and composite materials with equivalent properties, which can effectively suppress structural deformation caused by ambient temperature fluctuations and ensure the dimensional stability of the base 1101 and the operating accuracy of the translation guide mechanism. The power output from the drive source 111 is precisely converted into stable linear motion of the moving part 114 along the axis of the roll 200 by the translation transmission mechanism 112, driving the detection component to complete continuous axial scanning of the roll surface of the roll 200.
[0042] The solution proposed in this application can achieve three different measurement methods: when the roll is stationary, the detection components are moved along the roll axis by the moving mechanism to measure the roll profile and axial temperature distribution; when the roll is rotating, multiple detection components distributed axially are used for synchronous measurement to evaluate the roll profile and roll surface temperature of multiple sections of the roll under dynamic conditions; by combining the continuous rotation of the roll with the axial movement of the detection components, a complete scan of the roll surface can be achieved, and the circumferential runout, roll profile and global temperature field of the roll surface can be obtained simultaneously.
[0043] See Figure 3 and Figure 4 In some embodiments, the first adjustment mechanism includes a first adjustment component 120 disposed at at least one end of the axial direction of the roll 200. The first adjustment component 120 is used to adjust the distance between the moving mechanism 110 and the roll 200 in a first direction. Specifically, the first adjustment component 120 includes a first connector 122 and a first adjustment component 123. The first connector 122 is movably mounted on the support 210 of the roll 200 in the first direction. The first adjustment component 123 is used to apply a first adjustment force to the first connector 122, causing the first connector 122 to drive the moving mechanism 110 to move along the first direction, thereby adjusting the distance between the moving mechanism 110 and the roll 200 in the first direction.
[0044] In this embodiment, the first adjustment component 120 can be located at one end of the axial direction of the roll 200 (e.g., the left end), or it can be symmetrically arranged at both ends of the axial direction of the roll 200 (e.g., one set at each of the left and right ends) to improve the adjustment stability and symmetry.
[0045] The first direction can be a direction perpendicular to the axis of the roll 200 and located in a vertical plane, such as the Z direction (i.e., the up-down direction). The first adjusting member 123 can be a manually operated adjusting screw or a fine-tuning micrometer, but is not limited to these. It can also be an electric adjusting mechanism, such as a ball screw pair driven by a stepper motor or a linear module driven by a servo motor, etc. This application does not limit this. In the scheme of this application, the displacement of the first connecting member 122 in the first direction is transmitted to the base 1101 which is rigidly connected to the translation transmission mechanism 112, thereby changing the relative offset between the axis of the guide rail 113 of the translation transmission mechanism 112 and the axis of the roll 200 in the first direction. This change in offset will cause a change in the overall spatial posture of the moving mechanism 110, so that when the moving mechanism 110 drives the detection component to move along the axial direction of the roll 200, the parallelism error between its trajectory and the axis of the roll 200 is reduced.
[0046] See Figure 2 and Figure 5 In some specific embodiments, the roll detection device 100 of this application includes a first straightening member 1311, which is disposed at least one end of the axial direction of the roll 200. For example, there can be two first straightening members 1311, which are fixedly installed relative to the base 1101 of the moving mechanism 110. The first straightening member 1311 includes a plurality of (e.g., three) tangent parts 1312 connected in sequence. A spatial reference is established by the plurality of tangent parts 1312 being tangent to the roll 200, thereby associating the spatial pose between the roll 200 and the base 1101, so that the base 1101 or the translation transmission mechanism is relatively parallel to the roll 200. Then, the Z direction of the base 1101 is further adjusted by the first adjusting component 120, thereby ensuring the accuracy of the moving direction of the translation transmission mechanism being parallel to the roll 200.
[0047] See Figure 4 In some specific embodiments, the first connecting member includes a fixing member 121. The first fixing member 121 and the first connecting member 122 can be plate-shaped or block-shaped. Both the fixing member 121 and the first connecting member 122 are connected to the fixing plate of the support base 210 of the roll 200. The fixing member 121 is fixedly connected to the fixing plate. The first connecting member 122 is provided with a plurality of elongated grooves extending in the vertical direction. The first connecting member 122 is slidably connected to the fixing plate by pins passing through the grooves. The first adjusting member is at least one threaded member provided on the fixing member 121 and threadedly connected to the first connecting member 122. Adjusting the threaded member allows the first connecting member 122 to move relative to the fixing member 121 in the Z direction, thereby driving the entire moving mechanism 110 to finely adjust the Z-direction height in a vertical plane perpendicular to the axis of the roll 200.
[0048] This application provides a first adjustment component 120 at at least one end of the axial direction of the roll 200. The first adjustment component 123 applies an adjustment force to the first connecting component 122, causing the first connecting component 122 to generate a certain displacement along the first direction. This displacement is then transmitted to the moving mechanism 110 through a rigid connection, thereby precisely controlling the parallelism between the moving mechanism 110 and the axis of the roll 200, and ensuring the geometric consistency of the scanning path of the detection component along the axial direction of the roll 200.
[0049] See Figure 5 In some embodiments, the first adjustment mechanism further includes a second adjustment component 130 disposed at at least one end of the axial direction of the roll 200. The second adjustment component 130 is used to adjust the distance of the moving mechanism 110 relative to the roll 200 in a second direction, wherein the first direction and the second direction are different. For example, when the first direction is the Z direction (perpendicular to the ground and parallel to the radial direction of the roll 200), the second direction is the Y direction (horizontal laterally, perpendicular to the axis of the roll 200 and parallel to the ground).
[0050] Specifically, the second adjustment assembly 130 includes a second connector 131 and a second adjustment member 132. The second connector 131 is disposed on the first connector and is movably mounted relative to the roll 200 in the second direction. The second adjustment member 132 is used to apply a second adjustment force to the second connector 131, so that the second connector 131 drives the moving mechanism 110 to move in the second direction, thereby adjusting the distance of the moving mechanism 110 relative to the roll 200 in the second direction.
[0051] The second connecting member 131 is a rigid structural component, and its mounting reference surface is in contact with the bearing surface of the first connecting member 122 or slidably connected through the guide rail 113. The second adjusting member 132 can be a mechanical manual adjusting member or an electric actuator. When it is a manual adjusting member, it includes an adjusting bolt. The adjusting bolt passes through the side plate 1241 fixed to the first connecting member 122 and abuts against the side of the second connecting member 131. By rotating in / out, the second connecting member 131 is pushed to translate along the second direction.
[0052] In some specific embodiments, a base plate 124 is fixed to the bottom of the first connecting member 122, and the bearing surface is the upper surface of the base plate 124. A side plate 1241 is provided between the base plate 124 and the first connecting member. The second connecting member 131 can be a pad that is disposed on the upper side of the base plate 124 and can slide with the base plate 124. The base 1101 of the moving mechanism 110 is supported on the pad, and the end of the first straightening member 1311 away from the roller 200 is fixedly connected to the pad. The second adjusting member 132 passes through the side plate 1241 and abuts against the side of the pad. With this arrangement, when adjusting the second adjusting member 132, the length of the second adjusting member 132 is used as the adjustable distance. When the second adjusting member 132 is turned, the pad moves relative to the base plate 124 in the Y direction, thereby realizing the parallelism compensation of the moving mechanism in the Y direction.
[0053] Based on the parallelism calibration in the first direction (e.g., Z-axis), this application uses the second adjustment component 130 to independently fine-tune in the orthogonal second direction (e.g., Y-axis), enabling the moving mechanism 110 to form a two-dimensional adjustable degree of freedom in the YZ plane. After the first connecting member moves along the Z-axis to correct the vertical angle between the base 1101 and the axis of the roll 200, the second connecting member 131 moves along the Y-axis to further eliminate the horizontal deflection caused by accumulated installation errors. This collaboratively achieves comprehensive correction of the spatial pose of the moving mechanism 110, ensuring that the sensor maintains an ideal detection distance and incident angle during subsequent axial scanning.
[0054] In some embodiments, the position adjustment system of this application further includes a second adjustment mechanism disposed on the moving part, the second adjustment mechanism being connected to the detection component and used to adjust the spatial position of the detection component relative to the roll 200. Specifically, the second adjustment mechanism may include a distance adjustment component, which is used to adjust the radial distance between the detection component and the roll surface of the roll 200. The distance adjustment component can apply a driving force along a second direction to the detection component, driving the detection component to move radially along the roll 200, the direction of movement being perpendicular to the axis of the roll 200. This radial movement changes the position of the detection component relative to the roll surface of the roll 200, thereby adjusting the detection distance between its sensing element and the roll surface of the roll 200.
[0055] In some embodiments, the distance adjustment assembly includes a mounting plate 115 fixed to the movable member 114 and a mounting block 140 disposed on the mounting plate 115, with the detection assembly mounted on the mounting block 140. The mounting block 140 is slidable relative to the mounting plate 115 in a second direction (Y direction), and the mounting plate 115 is provided with a fixing block 1401 corresponding to the mounting plate 115 in the second direction. The distance adjustment assembly also includes a third adjusting member, which can be at least one threaded member. The third adjusting member passes through the fixing block 1401 and is threadedly connected to the mounting block 140. Tightening the third adjusting member can drive the mounting block 140 to move along the mounting plate 115 in the second direction, thereby adjusting the radial distance between the detection assembly and the roll 200.
[0056] While maintaining a rigid connection between the detection component and the moving mechanism 110, this application drives the detection component to translate radially along the roll 200 through the distance adjustment component, enabling the detection component to adapt to rolls 200 with different diameter specifications and positioning the sensing element in the adjusted spatial position. This effectively suppresses nonlinear errors in laser ranging and misjudgments in infrared temperature emissivity caused by distance deviation, thereby improving the accuracy of roll surface attribute parameter detection.
[0057] See Figure 5 and Figure 6 In some specific embodiments, the roll detection device includes a second corrector 117 disposed on the second adjustment mechanism. The second corrector 117 is used to contact the roll surface of the roll 200 to determine the distance between the measuring component and the roll surface of the roll 200 through contact, thereby correcting the detection distance between the sensing element and the roll surface. The second adjustment mechanism includes a mounting portion 116 for detachably mounting the detection component or the second corrector 117. The second corrector 117 has an arcuate surface that contacts the roll surface. When the mounting portion 116 is installed with the second corrector 117, the distance between the mounting portion 116 and the roll surface of the roll 200 is determined by the surface contact state between the second corrector 117 and the roll surface of the roll 200, thereby determining the distance between the sensing element and the roll surface of the roll 200.
[0058] During the distance correction process, the second correction element 117 is first installed on the mounting part 116. Then, the radial distance between the mounting part 116 and the roll 200 is adjusted synchronously by the distance adjustment assembly, so that the arc surface of the second correction element 117 fits against the roll surface of the roll 200. After correction, the distance adjustment assembly is locked to position the mounting part 116 in the adjusted position. At this time, the second correction element 117 can be removed, and a sensing element can be installed on the mounting block 140. The roll surface parameters can then be detected through the sensing element. By correcting the detection distance, the detection distance of the sensing element can be made perpendicular to the roll surface of the roll 200, with a fixed spacing, which can improve the accuracy of the roll surface attribute parameter detection.
[0059] See Figure 5 In some embodiments, the second adjustment mechanism further includes an angle adjustment component for adjusting the pitch angle of the detection component relative to the roll 200. Specifically, the angle adjustment component includes an angle adjustment member and a mounting base 150, with the mounting part 116 disposed on the mounting base 150. The mounting base 150 has an arc-shaped guide structure, allowing the detection component to move along the arc-shaped guide structure and lock onto the mounting base 150 to adjust the pitch angle of the detection component relative to the roll 200. In this embodiment, the angle adjustment member can be a locking bolt embedded in the arc-shaped guide groove 151, which can slide within the arc-shaped guide groove 151, causing the mounting part 116 to pitch and rotate around the center of curvature of the arc-shaped guide groove 151. When the locking nut is tightened, the mounting part 116 is rigidly locked at the current pitch angle.
[0060] This embodiment, based on parallelism adjustment and radial distance adjustment, further introduces an angle adjustment component based on an arc-shaped guide structure. When the mounting part 116 slides along the arc-shaped guide groove 151 to the position to be detected and locks, the detection optical axis of the detection component is continuously perpendicular to the local curved surface of the roll 200. This avoids the incident angle deviation caused by the slight curvature of the roll surface, further improving the accuracy and stability of the roll shape and roll surface temperature parameters of the roll 200. This allows for rapid adjustment of the curvature of the roll 200 to achieve the target value for various product models, thereby ensuring the consistency of the electrode thickness and effectively improving the production efficiency of the electrode rolling process.
[0061] Accordingly, this application also provides a roll adjustment method based on the roll detection device of the above embodiment. See also Figure 8 The method includes the following steps: S110. The start-up control unit applies a control effect to the roll and controls the roll detection device to obtain the current roll surface attribute parameters in real time.
[0062] In this implementation, while the control unit applies a control effect to the roll, the driving mechanism 110 moves the detection component at a constant speed along the axial direction of the roll 200, simultaneously collecting roll surface attribute parameters at various locations. These parameters may include roll surface curvature data and / or roll surface temperature data. The roll surface curvature data includes axial profile data, circumferential runout data, and local curvature distribution; the roll surface temperature data includes temperature field data distributed along both the axial and circumferential directions.
[0063] S120. Compare and calculate the current roller surface attribute parameters with the preset target roller surface attribute parameters to obtain the error value that characterizes the difference between the current roller surface attribute parameters and the preset target roller surface attribute parameters.
[0064] In this step, a numerical difference operation is performed between the current roller surface attribute parameters and the target roller surface attribute parameters. The error value is obtained based on the result. The target roller surface attribute parameters are a set of expected parameters set by the user. Their contents are consistent with the roller surface attribute parameter types mentioned above, including target axial profile, target circumferential runout, target curvature distribution, or target temperature field distribution, etc.
[0065] S130. Adjust the control unit according to the error value to make the current roll surface attribute parameters of the roll approach the target roll surface attribute parameters.
[0066] In this step, the control unit is adjusted according to the error value to change its output intensity, direction of action, duration or output temperature, so that the current roll surface attribute parameters of the roll approach the target roll surface attribute parameters and are stable within the allowable tolerance range.
[0067] The technical solution provided in this application can dynamically adjust the output of the control unit by comparing and calculating the current roll surface attribute parameters with the target parameters in real time, so that the roll surface attribute parameters are close to the target roll surface attribute parameters. This realizes a loop control mechanism, effectively ensuring the consistency of the roll surface attribute parameters with the target requirements during the control process. It can stably control the roll surface attribute parameters within the allowable tolerance range, thereby effectively improving the control accuracy of the roll surface curvature.
[0068] See Figure 9 In some embodiments, the method of this application includes the following steps: S210. Control the roll detection device to obtain the initial roll surface attribute parameters of the roll, and establish a detection benchmark based on the initial roll surface attribute parameters.
[0069] In this step, after the measuring components are installed and the rolls and detection components are aligned, the moving mechanism drives the detection components to move laterally for measurement while the force control mechanism and temperature control mechanism are not activated. The encoder of the moving mechanism drive source, combined with the encoder of the roll rotation motor, can record the initial state of each position point on the roll surface in real time, thereby fitting the axial direction of the roll and the axial base roll type and roll temperature, and calibrating the zero position reference of the roll.
[0070] S220: The start-up control unit applies a control effect to the roll and controls the roll detection device to obtain the current roll surface attribute parameters in real time.
[0071] In this step, the target roller surface attribute parameters are input, such as the target roller surface curvature parameters and the target roller surface temperature parameters. Then, the temperature control mechanism and the force control mechanism are started, which can measure the changes in the roller surface curvature and roller surface temperature parameters in real time.
[0072] S230. Compare and calculate the current roller surface attribute parameters with the preset target roller surface attribute parameters to obtain the error value that characterizes the difference between the current roller surface attribute parameters and the preset target roller surface attribute parameters.
[0073] Here, error refers to the numerical difference between the current roller surface attribute parameters and the target roller surface attribute parameters at the same spatial sampling point. This difference can be the curvature deviation or temperature deviation at a certain point. The error value is obtained by comparing the detected parameters with the input target parameters in real time.
[0074] S240. Generate adjustment instructions based on the arc error value, and control the force control mechanism to output adjustment force to the roll for adjusting the roll surface arc, so that the current roll surface arc parameter of the roll approaches the target roll surface arc parameter.
[0075] In this embodiment, the control unit includes a force control mechanism. Based on the target roll surface curvature parameters, the force control mechanism 300 applies a force in a specific direction to the roll 200. During this process, a closed-loop feedback control algorithm continuously monitors, dynamically calculates, and responds in real time, mapping the curvature error to the power output adjustment of the temperature control mechanism or the load applied by the force control mechanism. This achieves real-time adjustment of the roll profile.
[0076] S250: Generate adjustment instructions based on temperature error values, and control the temperature control mechanism to adjust the roll surface temperature of the roll so that the current roll surface temperature parameter of the roll approaches the target roll surface temperature parameter.
[0077] The control unit includes a temperature control mechanism, or adjusts the roll temperature based on the target roll surface temperature parameter. During this process, a closed-loop feedback control algorithm continuously monitors, dynamically calculates, and responds in real time, mapping the temperature error to the power output adjustment of the temperature control mechanism, thus achieving real-time adjustment of the roll temperature. Cyclic detection and adjustment ensure that the current roll surface temperature parameter approaches the target roll surface temperature parameter. It is worth noting that steps S230 and S240 can be performed selectively, or both can be performed simultaneously.
[0078] The solution provided in this application compares the current roll surface attribute parameters with the target roll surface attribute parameters and calculates the error value. Then, it generates adjustment commands through a closed-loop feedback control algorithm, enabling the control unit to dynamically correct the control effect based on the real-time detection results. This allows the roll surface attribute parameters to be continuously controlled to approach the set target value during roll deflection or temperature changes, thereby achieving real-time adjustment and stable control of roll shape and roll temperature.
[0079] See Figure 7This application also provides a roll adjustment system, which includes the measuring device, control unit, and control system described above. The control unit includes a temperature control mechanism (not shown) for adjusting the temperature of the roll 200 and a force control mechanism for applying mechanical load to the roll 200. The control system is communicatively connected to the measuring device, the temperature control mechanism, and the force control mechanism. The control system includes a processor, which executes the method described in the above embodiment when running.
[0080] The temperature control mechanism is used to regulate the temperature of the roll 200. It can be a flow channel installed inside the roll 200, an array of electric heating wires embedded inside the roll 200, or a hot air circulation module surrounding the outer periphery of the roll 200. The support seats 210 at both axial ends of the roll 200 are equipped with force control input sections 211, which are connected to a force control mechanism 300. The force control mechanism 300 applies mechanical loads to the roll 200 through the force control input sections. Specifically, the force control mechanism 300 can be a hydraulic loading cylinder, a pneumatic push rod, or a servo electric push rod, etc., with the force control loading direction perpendicular to the roll surface of the roll 200. Both the temperature control mechanism and the force control mechanism 300 have independent actuator interfaces. They can operate independently or work together, for example, simultaneously applying preload during heating to compensate for roll shape changes caused by thermal expansion.
[0081] In this embodiment, the control system is communicatively connected to the measuring device, temperature control mechanism, and force control mechanism 300. The control system includes a processor, memory, input / output interface, and communication module. When the processor runs, it executes the method described above. When the control system runs, it first controls the detection component to acquire the roll surface attribute parameters of the roll 200 in its initial state, and establishes a joint axial and circumferential reference based on these parameters. Then, while controlling the control unit to apply a control effect to the roll 200 according to the target roll surface attribute parameters, it acquires the current roll surface attribute parameters in real time. The current roll surface attribute parameters are then compared with the target roll surface attribute parameters. Based on the error calculation results, a closed-loop feedback control algorithm is used to generate adjustment commands, and the output power of the temperature control mechanism and the loading force of the force control mechanism 300 are dynamically adjusted accordingly to make the roll surface attribute parameters of the roll 200 approach the target value.
