For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] Figure 1 This is a structural schematic diagram of a plate shape detection device according to an embodiment of the present utility model. This embodiment is applicable to situations where the plate shape of foil to be detected is being performed, such as... Figure 1 As shown, the plate shape detection device 100 includes: a base roller 110 and a flexible pressure-sensitive liner 120; wherein, the flexible pressure-sensitive liner 120 can be attached to the outer surface of the base roller 110 to acquire pressure distribution data of the foil in real time.

[0034] Optionally, in this embodiment, during the plate shape detection of the foil to be tested, the foil to be tested 130 is laid flat on the outer surface of the plate shape detection device 100, and the pressure data (i.e. pressure distribution data) applied by the foil to be tested to the plate shape detection device 100 is collected by each of the flexible pressure-sensitive pads 120, and the plate shape detection result of the foil to be tested is determined based on the pressure data.

[0035] The foil to be tested can be aluminum foil, copper foil, gold foil, or silver foil, etc., and is not limited in this embodiment. It should be noted that the size of the foil to be tested is not limited in this embodiment.

[0036] In an optional implementation of this embodiment, during the shape detection of the foil to be tested, the foil 130 to be tested can be laid flat on the outer surface of the shape detection device 100. Then, the pressure data of the foil to be tested applied to the shape detection device 100 can be collected by the flexible pressure-sensitive pad 120, thereby obtaining pressure distribution data. Further, the shape detection result of the foil to be tested can be determined based on the obtained pressure data, i.e., pressure distribution data. For example, the shape detection result can be flatness qualified, flatness unqualified, surface scratches, or uniform thickness, etc., which are not limited in this embodiment.

[0037] The plate shape detection device provided in this embodiment may include: a base roller and a flexible pressure-sensitive bushing; the flexible pressure-sensitive bushing is attached to the outer surface of the base roller and is used to acquire pressure distribution data of the foil in real time; it can facilitate the collection of pressure data of different positions of the foil needles on the plate shape detection device; it can quickly and accurately detect the plate shape of the foil, which helps to ensure the quality and performance of the foil.

[0038] Optionally, in this embodiment, the dimensions of the flexible pressure-sensitive liner are customized according to the shape and size of the base roller.

[0039] In one optional implementation of this embodiment, the size of the flexible pressure-sensitive liner 120 is not fixed. When the size of the base roller 110 is large, the size of the flexible pressure-sensitive liner 120 is also large. For example, the area of ​​the flexible pressure-sensitive liner 120 can be equal to or smaller than the area (or side area) of the base roller 110, so as to ensure that the flexible pressure-sensitive liner 120 covers the outer surface of the base roller 110.

[0040] Optionally, in this embodiment, the flexible pressure-sensitive liner includes a plurality of independent pressure-sensitive elements, which are arranged in a row and column cross pattern.

[0041] In an optional implementation of this embodiment, the flexible pressure-sensitive substrate 120 may include a plurality of pressure-sensitive elements, such as 100, 200, or 500, etc., and this embodiment is not limited thereto. It is understood that the more pressure-sensitive elements there are, the denser the pressure distribution data of the foil acquired by the flexible pressure-sensitive substrate 120, and the higher the detection accuracy.

[0042] In this embodiment, the pressure-sensing elements in the flexible pressure-sensing liner 120 can be arranged in a cross-row and cross-column manner, which can ensure that pressure data at each position of the foil is detected and prevent missed detection.

[0043] In a specific example of this embodiment, the flexible pressure-sensitive substrate 120 may include a printed circuit board (PCB) on which a matrix of pressure-sensitive elements is deployed; wherein the matrix of pressure-sensitive elements is composed of pressure-sensitive elements arranged in a cross-row and cross-column manner.

[0044] Optionally, in this embodiment, the base roller 110 can be cylindrical, meaning the contact surface between the foil to be tested and the plate shape detection device is rectangular; simultaneously, the base roller 110 has a hollow structure, and a rotating shaft is deployed inside the base roller. Figure 1 (not shown in the image), the rotating shaft is connected to the target motor ( Figure 1 (Not shown in the image) is connected and driven by the target motor to rotate the base roller 110 along the rotation axis.

[0045] The target motor can be a DC motor, a servo motor, or a stepper motor, etc., and this embodiment does not limit it.

[0046] In an optional implementation of this embodiment, the base roller 110 can be a hollow structure, and a rotating shaft can be deployed inside the base roller 110, i.e., inside the hollow structure. The rotating shaft is connected to the target motor, and the rotation of the target motor can drive the rotating shaft to rotate, which can make the base roller 110 rotate.

[0047] The advantage of this setup is that the base roller can rotate continuously, which in turn changes the contact area between the foil to be tested and the shape detection device. This ensures that the shape of large areas of foil to be tested can be detected without human intervention.

[0048] Optionally, in this embodiment, the base roller 110 can also be arc-shaped. Figure 1 (Not shown in the figure, which is not a limitation of this embodiment), that is, the contact surface between the foil to be detected and the plate shape detection device can be circular or fan-shaped, etc.; the base roller is connected to the support structure, the support structure is connected to the target motor and driven by the target motor, so that the base roller moves with the movement of the support structure.

[0049] The support structure, which connects the base roller at one end and the target motor at the other end, can be a bracket, a base-type support structure, or a suspended support structure, etc., and is not limited to any particular type in this embodiment.

[0050] In an optional implementation of this embodiment, when the outer surface of the base roller 110 is arc-shaped, the base roller is connected to one end of the support structure, while the other end of the support structure is connected to the target motor. When the target motor rotates, the base roller can move along with the movement of the support structure.

[0051] The advantage of this setup is that by setting the base roller to an arc shape, the movement flexibility of the plate shape detection device is increased, which can adapt to complex experimental environments and reduce experimental space. At the same time, the base roller can rotate continuously, so that the contact area between the foil to be tested and the plate shape detection device can be changed continuously. This ensures that the plate shape of large-area foil to be tested can be detected without manual intervention.

[0052] Optionally, in this embodiment, the flexible pressure-sensitive liner 120 is a flexible pressure-sensitive liner; the flexible pressure-sensitive liner surrounds the outer peripheral surface of the base roller 110; or, multiple flexible pressure-sensitive liners are provided, covering the outer peripheral surface of the base roller without overlap along the axial and / or circumferential directions of the base roller.

[0053] In an optional implementation of this embodiment, the flexible pressure-sensitive liner 120 may surround the outer peripheral surface of the base roller, for example, as shown in... Figure 1 As shown, a flexible pressure-sensitive liner is provided on the outer peripheral surface of the base roller 110.

[0054] In another optional implementation of this embodiment, multiple flexible pressure-sensitive liners 120 are provided, which cover the outer peripheral surface of the base roller without overlap along the axial and / or circumferential directions of the base roller.

[0055] Figure 2 This is a structural schematic diagram of another plate shape detection device provided according to an embodiment of the present utility model, as shown below. Figure 2As shown, the flexible pressure-sensitive liner 120 has three strip structures spaced apart along the axial direction of the base roller 110 (each strip structure can have multiple flexible pressure-sensitive liners deployed).

[0056] It is understood that in this embodiment, the number of detection points (i.e. pressure sensing elements) in a flexible pressure-sensitive liner can be the same. That is, the detection points deployed in a strip-shaped flexible pressure-sensitive liner are the same as the detection points of the flexible pressure-sensitive liner surrounding the outer peripheral surface of the base roller. In other words, the detection accuracy of deploying multiple spaced flexible pressure-sensitive liners is higher than the detection accuracy of the flexible pressure-sensitive liner surrounding the outer peripheral surface of the base roller.

[0057] Based on this, in this embodiment, the deployment method of the flexible pressure-sensitive liner can be determined based on different plate shape detection requirements. For example, if the detection accuracy is high in the plate shape detection requirements, the flexible pressure-sensitive liner can be deployed by covering the outer peripheral surface of the base roller without overlap along the axial and / or circumferential directions of the base roller; if the detection accuracy is low in the plate shape detection requirements, the flexible pressure-sensitive liner can be wrapped around the outer peripheral surface of the base roller.

[0058] The advantage of this setup is that different sensor deployment methods can be set based on different plate shape detection requirements, increasing the system's flexibility.

[0059] Figure 3 This is a schematic diagram of another plate shape detection device provided according to an embodiment of the present utility model; as shown Figure 3 As shown, the plate shape detection device may further include a controller 140, wherein the controller 140 can be communicatively connected to the flexible pressure-sensitive bushing 120.

[0060] Optionally, in this embodiment, the controller 140 can be used to receive the pressure distribution data of the foil and determine the foil shape detection result based on the pressure distribution data of the foil.

[0061] In a specific implementation, the controller 140 can be used to receive pressure distribution data of the foil to be tested collected by each of the flexible pressure-sensitive bushings, analyze the pressure distribution data, and determine the plate shape detection result of the foil to be tested based on the analysis result of the pressure distribution data.

[0062] In this embodiment, after the flexible pressure-sensitive liner 120 collects the pressure distribution data of the foil to be tested, it can transmit the pressure distribution data to the controller 140 so that the controller 140 can analyze the pressure distribution data and then determine the plate shape detection result of the foil to be tested based on the analysis result of the pressure distribution data.

[0063] Optionally, in this embodiment, the controller 140 can be specifically used to determine whether there are target pressure data in the pressure distribution data that do not meet the preset pressure range; if the number of target pressure data is less than a set number threshold, the plate shape detection result is determined to be qualified; otherwise, it is unqualified.

[0064] The preset pressure range can be determined based on the material properties, thickness, or size of the plate to be tested. This embodiment does not limit its specific numerical range.

[0065] The set quantity threshold can be 10, 20, or 50, etc., and this embodiment does not limit it.

[0066] In this embodiment, after receiving the pressure distribution data collected by the flexible pressure-sensitive bushing 120, the controller 140 can further determine whether there is pressure data in the pressure distribution data that does not meet the preset pressure range. In this embodiment, this is referred to as target pressure data. For example, if the first pressure data significantly exceeds the preset pressure range, then the first pressure data can be determined as target pressure data.

[0067] Furthermore, the number of target pressure data points can be counted. If the number of target pressure data points, for example, 5, is less than the set threshold (10), then the plate shape test result of the foil to be tested can be determined to be qualified; otherwise, it is unqualified.

[0068] The advantage of this setup is that it can quickly identify abnormal data in the pressure distribution data and quickly obtain the plate shape detection results of the foil to be tested based on the number of abnormal data, thus improving detection efficiency while ensuring detection accuracy.

[0069] Optionally, in this embodiment, the controller 140 can also be specifically used to generate a pressure cloud map based on the pressure distribution data, and determine abnormal areas in the pressure cloud map; if the area of ​​the abnormal area is determined to be less than a set percentage threshold in the pressure cloud map, the plate shape detection result is determined to be qualified; otherwise, it is unqualified.

[0070] The pressure cloud map can be a two-dimensional cloud map or a three-dimensional cloud map; this embodiment does not limit it.

[0071] In this embodiment, after receiving the pressure distribution data collected by the flexible pressure-sensitive bushing 120, the controller 140 can further preprocess the received pressure distribution data. For example, it can clean and format the data, including removing outliers and filling in missing values. Furthermore, the pressure magnitude can be represented by color gradients. For example, if the generated pressure cloud map is a two-dimensional cloud map, different color chromatograms (such as rainbow chromatograms or grayscale chromatograms) can be selected to represent the pressure distribution data. If the generated pressure cloud map is a three-dimensional cloud map, height, color, or texture mapping can be selected to represent the pressure distribution data.

[0072] Understandably, during the pressure testing of the foil material, the smaller the change in the color or height of the generated pressure cloud map, the flatter the foil material is.

[0073] In an optional implementation of this embodiment, after generating a pressure cloud map based on pressure distribution data, abnormal areas can be further identified in the pressure cloud map. For example, areas with colors significantly different from the surrounding areas can be identified as abnormal areas; areas with heights significantly higher than the latter but lower than the surrounding areas can also be identified as abnormal areas. Furthermore, the percentage of the area of ​​the abnormal areas in the pressure cloud map area can be determined. If the percentage of the area of ​​the abnormal areas in the pressure cloud map is less than a set percentage threshold, the plate shape detection result is determined to be qualified; otherwise, it is unqualified.

[0074] The set percentage threshold can be 5%, 10%, or 20%, etc., and is not limited to this embodiment.

[0075] The advantage of this setup is that it allows the plate shape detection device to visually observe abnormal areas, providing a basis for rapid and accurate detection of the foil material to be tested.

[0076] Optionally, in this embodiment, the controller 140 can also be communicatively connected to the base roller 110 and is also used to control the rotation of the base roller 110.

[0077] In an optional implementation of this embodiment, the controller can determine the number of rotations required for the base roller 110 based on the size information of the foil to be detected, and control the base roller 110 to rotate based on the number of rotations. This ensures that all areas of the foil to be detected are detected, thereby improving the detection accuracy of the plate shape detection device.

[0078] In another optional implementation of this embodiment, the controller 140 can also be communicatively connected to the target motor; the controller is used to send control signals to the target motor to make the target motor rotate.

[0079] In an optional implementation of this embodiment, the controller can also be connected to the motor in communication. In a specific implementation, the controller can determine the number of rotations required for the base roller 110 based on the size information of the foil to be detected, and can determine the rotation amount of the target motor based on the size information, convert the rotation amount into a control signal and transmit it to the target motor so that the target motor rotates based on the control signal, thereby driving the base roller 110 to rotate.

[0080] The advantage of this setup is that it allows for accurate determination of the target motor's rotation, ensuring that all areas of the foil to be inspected are detected, thus improving the inspection accuracy of the plate shape detection device.

[0081] Optionally, in this embodiment, the plate shape detection device may further include: a display module 150; the display module 150 is communicatively connected to the controller 140; the display module 150 is used to display the pressure value of each pressure sensing element and the pressure distribution data of the foil and / or the plate shape detection result of the foil to be detected.

[0082] In an optional implementation of this embodiment, the plate shape detection device may further include a display module 150; the display module 150 may be communicatively connected to the controller 140.

[0083] Optionally, the display module 150 can display the pressure data detected by the flexible pressure-sensitive bushing 120; for example, the pressure data can be displayed in the form of a table or a graph; the display module can also display the shape detection result of the foil to be tested; for example, the pressure cloud map and the shape detection result of the foil to be tested determined based on the pressure cloud map can be displayed simultaneously.

[0084] The advantage of this setup is that it enriches the functionality of the sheet shape detection device, allowing users to view the sheet shape detection results of the foil material to be tested in real time, thus improving the user experience.

[0085] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
