Detailed Implementation

[0048] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0049] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0050] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0051] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0052] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0053] First, it should be noted that the X, Y, and Z directions mentioned in this application are referred to in the appendix. Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 8 , Figure 9 , Figure 10 and Figure 12 The marked directions. Among them, the axes in the X direction, Y direction, and Z direction intersect each other.

[0054] like Figures 1-14 As shown, a web-correcting device 100 provided according to an embodiment of this application includes a web-correcting mechanism 3, a monitoring mechanism 2, and a roller assembly 1; the web-correcting mechanism 3 is used to correct the web-correcting of the conveyed foil 200; the monitoring mechanism 2 and the web-correcting mechanism 3 are disposed along the Z direction on the web-correcting mechanism 3, and the monitoring mechanism 2 is used to monitor the tension of the foil 200; the roller assembly 1 is disposed along the Z direction on the monitoring mechanism 2, and the roller assembly 1 is used to convey the foil 200.

[0055] like Figures 1-3 As shown, the correction device 100 includes a correction mechanism 3, a monitoring mechanism 2, and a roller assembly 1; wherein, the correction mechanism 3 is used to correct the deviation of the conveyed foil 200; the monitoring mechanism 2 is used to monitor the tension of the foil 200 to avoid deformation, wrinkling or breakage of the foil 200 due to excessive or insufficient tension during the conveying process; the roller assembly 1 is used to convey the foil 200.

[0056] To further explain, the roller assembly 1 is mounted on the monitoring mechanism 2 in the Z direction, and the monitoring mechanism 2 is mounted on the correction mechanism 3 in the Z direction. It can be understood that the roller assembly 1, the monitoring mechanism 2, and the correction mechanism 3 are arranged sequentially along the Z direction. The roller assembly 1 is used to transport the foil 200, the monitoring mechanism 2 can detect the tension of the foil 200, and the correction mechanism 3 can correct the position of the foil 200. In other words, the correction mechanism 3 can drive the monitoring mechanism 2 and the roller assembly 1 to move together, thereby correcting the position of the foil 200.

[0057] In this application, the monitoring mechanism 2 and the correction mechanism 3 are integrated together to realize tension measurement and correction functions; the roller assembly 1, the monitoring mechanism 2 and the correction mechanism 3 are arranged sequentially along the Z direction. This arrangement effectively reduces the three-dimensional size of the device, making the correction device 100 compact in structure and occupying less space, which can effectively improve space utilization.

[0058] In one optional embodiment, the monitoring mechanism 2 includes a first magnet assembly 21, a second magnet assembly 22, and a first detection assembly 23; the first magnet assembly 21 and the second magnet assembly 22 are spaced apart in the Z direction, the magnetic pole of the first magnet assembly 21 facing the second magnet assembly 22 is a first magnetic pole, and the magnetic pole of the second magnet assembly 22 facing the first magnet assembly 21 is a second magnetic pole, the first magnetic pole and the second magnetic pole are the same, and the monitoring mechanism 2 is located on the side of the first magnet assembly 21 away from the second magnet assembly 22; the first detection assembly 23 is used to detect the distance between the first magnet assembly 21 and the second magnet assembly 22.

[0059] In related technologies, the tension detection sensors typically used by monitoring agencies 2 are mainly resistance strain gauges. These strain gauges may have the following problems during detection: strain gauge detection may experience temperature drift in actual use, and the measurement accuracy will decrease as the measurement time changes; or, strain gauge measurement is a contact force measurement, and during the measurement process, the vibration of the mechanical structure will cause the strain gauge to follow the vibration, resulting in measurement fluctuation errors and reducing the accuracy of the coil tension measurement.

[0060] like Figure 4 and Figure 5As shown, the monitoring mechanism 2 of this application includes a first magnet assembly 21, a second magnet assembly 22, and a first detection assembly 23. The first magnet assembly 21 and the second magnet assembly 22 are spaced apart in the Z direction, and there is a gap between the first magnet assembly 21 and the second magnet assembly 22. The side of the first magnet assembly 21 facing the second magnet assembly 22 is the first magnetic pole, and the side of the second magnet assembly 22 facing the first magnet assembly 21 is the second magnetic pole. The first magnetic pole and the second magnetic pole are the same, so a repulsive force will be generated between the first magnet assembly 21 and the second magnet assembly 22. The roller assembly 1 is located on the side of the first magnet assembly 21 away from the second magnet assembly 22. The first detection assembly 23 is used to detect the distance between the first magnet assembly 21 and the second magnet assembly 22.

[0061] In this embodiment, based on the balance of forces, when the tension of the foil 200 changes, the foil 200 is pressed by the roller assembly 1 in the Z direction towards or away from the first magnet assembly 21 and the second magnet assembly 22. The repulsive force between the first magnet assembly 21 and the second magnet assembly 22 will change accordingly. The change in the repulsive force is also the change in the distance between the first magnet assembly 21 and the second magnet assembly 22. The change in the distance between the first magnet assembly 21 and the second magnet assembly 22 is detected by the first detection assembly 23 to indirectly measure the change in the tension of the foil 200. This embodiment detects the change in the tension of the foil 200 by changing the position of the first magnet assembly 21 and the second magnet assembly 22, which can avoid the influence of temperature drift on the measurement results, thereby improving the stability and accuracy of the measurement results.

[0062] In an optional embodiment, the monitoring mechanism 2 further includes a guide component 24, the second magnet component 22 is disposed on the guide component 24, the first magnet component 21 is slidably connected to the guide component 24, and the first magnet component 21 is capable of moving relative to the guide component 24 in the Z direction toward or away from the second magnet component 22.

[0063] like Figure 4 and Figure 5 As shown, the monitoring mechanism 2 also includes a guide component 24. The second magnet component 22 is fixedly connected to the guide component 24, and the first magnet component 21 is slidably connected to the guide component 24. The first magnet component 21 will move relative to the guide component 24 in the Z direction. That is, the first magnet component 21 moves towards the second magnet component 22 in the Z direction, or moves away from the second magnet component 22 in the Z direction. The guide component 24 provides guidance for the movement of the first magnet component 21 to avoid the first magnet component 21 from deflecting during the movement, so as to further avoid the foil 200 from deflecting.

[0064] The guide component 24 can be a guide post or a chute.

[0065] In one specific implementation, the first detection component 23 may employ an optical fiber sensor, using optical fiber as a sensing element to measure the distance between the first magnet component 21 and the second magnet component 22 through the transmission and reflection of light signals.

[0066] In another specific embodiment, the first detection component 23 is a distance detection sensor, which is located between the first magnet component 21 and the second magnet component 22. The distance detection sensor detects the change in distance between the first magnet component 21 and the distance detection sensor, thereby detecting the change in distance between the first magnet component 21 and the second magnet component 22, and thus obtaining the tension change of the foil 200.

[0067] In another specific implementation, such as Figure 5 As shown, the first detection component 23 is a distance detection sensor, which is disposed on the guide component 24 and located above the first magnet component 21 in the Z direction. By moving the first magnet component 21 relative to it in the Z direction, the distance detection sensor can detect the change in distance between the first magnet component 21 and the distance sensor, that is, it can detect the change in distance between the first magnet component 21 and the second magnet component 22. In this embodiment, the distance detection sensor is not directly connected to the roller component 1, so the actual measurement result will not be affected by the mechanical vibration of the roller component 1, which can effectively reduce the fluctuation of the measurement value and improve the stability and accuracy of the measurement result.

[0068] In this process, the foil 200 passes through the roller assembly 1. The tension of the foil 200 is balanced by the repulsive forces of the first magnet assembly 21 and the second magnet assembly 22. The distance measurement sensor measures the change in the positional distance between the first magnet assembly 21 and the second magnet assembly 22, and the tension can be calculated from the relationship between the repulsive force and the distance. In actual experimental equipment, the relationship curve between the magnetic repulsive force and the distance is combined with experimental determination using standard weights to calibrate the relationship curve, thus obtaining more accurate measurement results.

[0069] In one alternative implementation, such as Figure 2 As shown, the monitoring mechanism 2 also includes a shield 25, inside which the first magnet assembly 21 and the second magnet assembly 22 are located; the shield 25 can prevent the first magnet assembly 21 and the second magnet assembly 22 from being interfered with by external magnetic fields, thereby further improving the stability and accuracy of the measurement results.

[0070] In one optional embodiment, the correction mechanism 3 includes a stator assembly 31, a mover assembly 32, a second detection assembly 33, and a control assembly; the mover assembly 32 is movable or rotatable relative to the stator assembly 31, and the monitoring mechanism 2 is disposed on the mover assembly 32; the foil 200 passes through the second detection assembly 33, which is used to detect the position of the foil 200; the control assembly is electrically connected to the mover assembly 32 and electrically connected to the second detection assembly 33.

[0071] In related technologies, the automatic correction mechanism 3 of foil 200 is usually driven by a motor, and the movement of the correction mechanism 3 is controlled by the motor driver to adjust the position of foil 200. The manufacturing cost of the motor and motor driver in this solution is relatively high.

[0072] like Figures 6-14 As shown, the correction mechanism 3 includes a stator assembly 31, a mover assembly 32, a second detection assembly 33, and a control assembly. The monitoring mechanism 2 is mounted on the mover assembly 32, meaning that the roller assembly 1 is indirectly connected to the mover assembly 32. The second detection assembly 33 is used to detect whether the foil 200 has shifted. The mover assembly 32 can move or rotate relative to the stator assembly 31. The control assembly is electrically connected to the second detection assembly 33 and the mover assembly 32. Specifically, when the second detection assembly 33 detects that the foil 200 has shifted, it sends a signal to the control assembly. The control assembly adjusts the magnitude and direction of the current in the mover assembly 32 according to the signal from the second detection assembly 33, thereby driving the mover assembly 32 to move or rotate relative to the stator assembly 31. This adjusts the position of the monitoring mechanism 2, which in turn adjusts the position of the roller assembly 1, and thus adjusts the position of the foil 200.

[0073] In this embodiment, the structure of the correction mechanism 3 is simplified. The correction mechanism 3 uses the basic principle that the mover assembly 32 is energized and subjected to force in the magnetic field of the stator assembly 31 to realize the movement of the correction mechanism 3. Since the correction mechanism 3 of this application is not as complex as the structure of a servo motor or a stepper motor, the circuit of the control component is relatively simple, so the manufacturing cost is lower and the cost of the entire correction device 100 can be effectively reduced.

[0074] The second detection component 33 can be an edge position sensor, which detects the edge position of the foil 200 by emitting and receiving light signals; or, the second detection component 33 can be a vision detection system, which acquires images through a high-speed camera and combines them with image processing algorithms to detect the position of the edge of the foil 200.

[0075] The control component uses a PID control algorithm to control the magnitude and direction of the current through the energized coil 322, thereby driving the actuator component 32 to rotate or move to adjust the position of the foil 200.

[0076] PID stands for Proportional, Integral, and Differential. The PID control algorithm is a proportional-integral-derivative control algorithm. It combines proportional, integral, and derivative components into a single control algorithm and is used in continuous systems. This application only uses this control algorithm without any modifications.

[0077] In one specific embodiment, the correction mechanism 3 further includes a housing 34, the stator assembly 31 is disposed on the inner wall of the housing 34, the mover assembly 32 is disposed inside the housing 34, the stator assembly 31 surrounds the mover assembly 32, and the mover assembly 32 is rotatable about the axis in the Z direction.

[0078] like Figure 6 and Figure 7 As shown, the correction mechanism 3 also includes a housing 34, which includes an inner wall. The stator assembly 31 is disposed on the inner wall, and the mover assembly 32 is disposed inside the housing 34. The stator assembly 31 is disposed around the mover assembly 32.

[0079] Specifically, the stator assembly 31 includes multiple permanent magnets 311, which are circumferentially spaced around the inner wall of the housing 34. The mover assembly 32 includes a mounting base 321, an energized coil 322, and a mounting member 323. The mounting member 323 is connected to the mounting base 321, and the energized coil 322 is wound around the mounting member 323. The monitoring mechanism 2 is mounted on the mounting base 321. When the energized coil 322 of the mover assembly 32 is energized, mechanical energy is generated between the energized coil 322 and the permanent magnets 311 through electromagnetic interaction, thereby driving the mover assembly 32 to rotate around the Z-axis. This causes the foil 200 to oscillate, adjusting the position of the foil 200 and thus achieving correction. In this embodiment, the correction mechanism 3 has a simple structure and low cost.

[0080] In one alternative implementation, such as Figure 7 As shown, the correction mechanism 3 includes at least one first elastic element 35. One end of the first elastic element 35 is connected to the housing 34, and the other end of the first elastic element 35 is connected to the moving part assembly 32. When the moving part assembly 32 rotates around the Z-axis, the first elastic element 35 will give the moving part assembly 32 a force in the opposite direction, thereby ensuring the stability of the movement of the moving part assembly 32 and preventing the moving part assembly 32 from shaking during rotation.

[0081] Preferably, the correction mechanism 3 includes two first elastic elements 35, which are symmetrically arranged along the axis of the Z direction. One of the first elastic elements 35 is located above the moving part assembly 32 in the Z direction, and the other first elastic element 35 is located below the moving part assembly 32 in the Z direction. In this embodiment, by setting two first elastic elements 35 and their positions, the stability of the movement of the moving part assembly 32 can be further improved.

[0082] The first elastic element 35 can be a spring sheet, a coil spring, or a torsion spring.

[0083] In an optional embodiment, the correction mechanism 3 further includes a housing 34, the housing 34 forming a cavity 341, the stator assembly 31 being disposed on the inner wall of the cavity 341; the mover assembly 32 includes a first mounting plate 324, a second mounting plate 325, and an energized coil 322, the first mounting plate 324 and the second mounting plate 325 being spaced apart along the Z direction, the energized coil 322 being disposed on the first mounting plate 324, the first mounting plate 324 being located inside the cavity 341, the second mounting plate 325 being located outside the cavity 341, the monitoring mechanism 2 being disposed on the second mounting plate 325, and the mover assembly 32 being movable relative to the stator assembly 31 along the X direction.

[0084] like Figures 8-14 As shown, the correction mechanism 3 also includes a housing 34, which has a cavity 341. The cavity 341 includes an inner wall, and the stator assembly 31 is disposed on the inner wall of the cavity 341. The mover assembly 32 includes a first mounting plate 324, a second mounting plate 325, and an energized coil 322. The first mounting plate 324 and the second mounting plate 325 are spaced apart along the Z direction, and a first region is formed between the first mounting plate 324 and the second mounting plate 325. The energized coil 322 is disposed on the first mounting plate 324. The first mounting plate 324 is located in the cavity of the housing 34. Inside cavity 341, the second mounting plate 325 is located outside cavity 341. It can be understood that the second mounting plate 325 is located above cavity 341 in the Z direction. Part of housing 34 is in the first area. Monitoring mechanism 2 is set on the second mounting plate 325. The first mounting plate 324 can move in the X direction in cavity 341 due to the action of stator assembly 31 and energized coil 322. As a result, the second mounting plate 325 will also move in the X direction. Therefore, it can drive foil 200 to move in the X direction to adjust the position of foil 200 to achieve correction.

[0085] To further explain, the stator assembly 31 includes multiple permanent magnets 311, which are disposed on the inner wall of the cavity 341; the energized coil 322 of the mover assembly 32 is located inside the cavity 341; when the energized coil 322 of the mover assembly 32 is energized, mechanical energy is generated between the energized coil 322 and the permanent magnets 311 through electromagnetic interaction, thereby driving the mover assembly 32 to move along the X direction, thereby driving the foil 200 to move along the X direction to adjust the position of the foil 200, thus achieving correction. In this embodiment, the correction mechanism 3 has a simple structure and low cost.

[0086] In one alternative embodiment, the housing 34 includes a first sidewall 342 and a second sidewall 343 located outside the cavity 341, the first sidewall 342 and the second sidewall 343 being arranged opposite to each other along the X direction;

[0087] The correction mechanism 3 further includes a second elastic element 36 and a third elastic element 37. One end of the second elastic element 36 is connected to the side of the second mounting plate 325 facing the first sidewall 342, and the other end of the second elastic element 36 is connected to the first sidewall 342. One end of the third elastic element 37 is connected to the side of the second mounting plate 325 facing the second sidewall 343, and the other end of the third elastic element 37 is connected to the second sidewall 343.

[0088] like Figures 11-14 As shown, the housing 34 includes a first sidewall 342 and a second sidewall 343, which are arranged opposite to each other in the X direction. The first sidewall 342 and the second sidewall 343 are located outside the cavity 341 and above the cavity 341 in the Z direction. The second mounting plate 325 is located between the first sidewall 342 and the second sidewall 343. The mover assembly 32 is movable between the first sidewall 342 and the second sidewall 343 in the X direction.
