[0072] The technical solutions of this disclosure will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure. Furthermore, the technical features involved in the different embodiments of this disclosure described below can be combined with each other as long as they do not conflict with each other.

[0073] Platform inspection refers to the inspection of the processing platform of tooling equipment in one or more dimensions. Taking mechanical pressing equipment as an example, the pressing equipment includes an upper platform and a lower platform. The pressing process of the product is achieved by applying preset pressure to the upper and lower platforms. Before the pressing equipment presses the product, it is necessary to inspect and correct the flatness and deflection error of the platform surface of the mechanical pressing equipment, so as to ensure the pressure uniformity of the pressing equipment and improve the processing accuracy of the pressing equipment.

[0074] In related technologies, measuring instruments such as levels can be used to detect platform deflection angle errors. However, level testing is complex and costly, and it primarily detects platform deflection angles in the horizontal direction, making it difficult to test platforms with special orientations. Therefore, the platform testing methods in these technologies are complex, costly, and have significant limitations.

[0075] In view of the deficiencies existing in the above-mentioned related technologies, the present disclosure provides a platform testing device and method, and a storage medium, which aims to simplify the platform testing process and improve the platform testing accuracy.

[0076] This disclosure provides a platform inspection device for inspecting the processing platform of tooling equipment. For example, in some embodiments, the processing platform described in this disclosure may be the processing platform of a pressing device.

[0077] like Figure 1 As shown, in some embodiments, the platform detection apparatus of this disclosure includes a body 310 and a detection probe. The body 310 is the main structure of the platform detection apparatus, having an upper surface and a lower surface on opposite sides.

[0078] The detection probe includes a plurality of lower probes 320 distributed on the lower surface. The root of each lower probe 320 is connected to the body 310 via a driving device, so that each lower probe 320 can be driven to extend and retract in a direction perpendicular to the lower surface. The specific structure of the driving device will undoubtedly be understood and fully implemented by those skilled in the art upon reference to relevant technologies, and will not be elaborated further in this disclosure.

[0079] In this embodiment of the disclosure, the platform detection device further includes a gyroscope, which is located inside the body 310 and can detect the position and pose information of the body 310 in real time. In some embodiments, the gyroscope can be any suitable type, such as a three-axis gyroscope, a six-axis gyroscope, etc., and this disclosure does not limit it.

[0080] The platform detection device also includes a controller, which can be located inside the main body 310. The controller can control the extension and retraction of the lower probe based on the difference between the pose information detected by the gyroscope and the target pose.

[0081] It is understood that the target pose represents the desired standard pose of the platform. For example, in some embodiments, the target pose may include a horizontal pose, that is, the platform surface is expected to be horizontal. Of course, in other embodiments, the target pose may be any other platform pose suitable for implementation, such as a tilted pose, etc., and this disclosure does not limit it.

[0082] In this embodiment of the present disclosure, when the platform detection device is freely placed on the platform to be tested, the gyroscope can collect the current pose information of the body 310. The controller can determine the difference between the current pose of the body 310 and the target pose based on the pose information, thereby controlling the extension and retraction of each lower probe 320 so that the current pose of the body 310 is consistent with the target pose. At this time, the detection result of the platform to be tested can be obtained based on the extension and retraction data of each lower probe 320.

[0083] To facilitate a clear understanding of the principle of the platform detection device according to the embodiments of this disclosure, in Figure 1 Based on the detection device shown, this disclosure provides a platform detection method that can be executed by the controller of the detection device.

[0084] like Figure 2 As shown, in some embodiments, the platform detection method of this disclosure includes:

[0085] S210. When the detection device is freely placed on the first platform to be detected, acquire the position and orientation information of the detection device.

[0086] S220. Based on the difference between the pose information and the preset target pose, control the extension and retraction of each lower probe of the detection device until the pose information is consistent with the target pose, and determine the first extension and retraction data of the lower probe.

[0087] S230. Determine the detection result of the first platform to be tested based on the first stretching data.

[0088] In this embodiment of the disclosure, the first platform to be tested is a processing platform that requires platform deflection angle error detection, for example... Figure 3 As shown, platform 100 is the first platform to be tested. Figure 3 In the example implementation, the target pose of the first platform 100 to be tested is in the horizontal direction, that is, it is necessary to use the platform detection device and method of the present disclosure to determine whether there is a deflection angle error of the surface of the first platform 100 to be tested relative to the horizontal plane.

[0089] When testing the first platform 100 to be tested, the testing device can be freely placed on the surface of the first platform 100 to be tested. The position and pose information of the body 310 can be collected by the gyroscope inside the body 310 of the testing device.

[0090] like Figure 3 As shown in (a), in the initial state of the detection device, the extension and retraction lengths of each lower probe 320 are consistent. Therefore, when the first platform to be tested 100 has a deflection angle error, the pose information of the body 310 collected by the gyroscope is different from the target pose (horizontal direction).

[0091] The detection device can control the extension and retraction of the lower probe 320 based on the difference between the pose information detected by the gyroscope and the target pose, thereby adjusting the pose of the body 310 so that the pose information of the body 310 detected by the gyroscope is consistent with the target pose. That is... Figure 3 As shown in (b), the body 310 is adjusted from its original tilted posture to a horizontal posture by extending and retracting the lower probe 320.

[0092] It is understood that when the pose information of the body 310 is consistent with the target pose, the distribution of the ends of the lower probes 320 can reflect the pose of the first platform 100 to be tested. Therefore, in this embodiment of the present disclosure, the detection device can determine the extension data of each lower probe 320 after the pose information of the body 310 is consistent with the target pose, and determine the first extension data based on the extension data of each lower probe 320.

[0093] The first extension data can directly reflect the position and orientation of the first platform 100 to be tested, so that the testing device can determine the testing result of the first platform 100 to be tested based on the first extension data.

[0094] Still with Figure 3 As shown in the example, Figure 3 As shown in (b), after the detection device controls the extension and retraction of the lower probes 320 to maintain the horizontal pose of the main body 310, it can lock the extension and retraction length of each lower probe 320, and then determine the first extension and retraction data based on the extension and retraction length of each lower probe 320. The first extension and retraction data is the pose data of the first platform 100 to be tested, simulated by the lower probes 320, and thus, it can be determined whether the first platform 100 to be tested has a deflection angle error based on the first extension and retraction data.

[0095] For example, in one instance, if the lengths of the lower probes 320 included in the first stretching data are consistent or have very small differences, it indicates that the first platform to be tested 100 is almost identical to the target pose, and it can be considered that there is no or only a very small deflection angle error.

[0096] For example, in another example, the lengths of the various lower probes 320 included in the first stretch data are inconsistent, for example... Figure 3 As shown, the length of the lower probe 320 gradually increases from left to right, indicating that there is a deflection angle error between the first detection platform 100 and the target pose. The specific deflection angle can be determined by using a preset algorithm based on the first extension data and the target pose.

[0097] As can be seen from the above, in this embodiment of the present disclosure, the lower probe of the detection device is used to simulate the pose of the first platform to be tested, which can automatically realize the error detection of the platform deflection angle. The operation is simple, and the detection device has a simple structure, high detection accuracy, and improves the platform detection effect.

[0098] In some platform testing scenarios, it is often necessary to perform error detection on the platform in multiple dimensions. Taking mechanical pressing equipment as an example, when testing the platform of the pressing equipment, in addition to detecting the platform deflection angle error, it is often necessary to detect the flatness of the platform surface. This is because if there are unevenness on the platform surface, it will cause uneven stress on various parts of the product during the pressing process, resulting in poor pressing effect.

[0099] In related technologies, pressure-sensitive paper is often used to test the flatness of a platform surface. The pressure-sensitive paper produces different shades of color under different pressures. Therefore, by observing the color distribution of the pressure-sensitive paper, it is possible to determine whether there are unevenness errors on the platform surface.

[0100] As can be seen, in related technologies, the detection of platform surface flatness and deflection error requires separate testing, which is cumbersome. Furthermore, using the color change of pressure-sensitive paper to detect flatness is not objective enough and is greatly affected by the operator's subjective experience, resulting in large detection errors.

[0101] In this embodiment, the platform detection device can be used to simultaneously detect the platform deflection angle error and the platform surface flatness. The following embodiments will be described in detail.

[0102] In some embodiments, the detection device of this disclosure also includes a pressure sensor. For example... Figure 1 As shown in the embodiment, the pressure sensor can be disposed inside the body 310, and the detection end is connected to each detection probe, thereby detecting and collecting pressure information of each lower probe 320, such as pressure value and pressure direction. In one example, the pressure sensor can be a thin-film pressure sensor, or any other sensor suitable for pressure detection can be used, and this disclosure does not limit it.

[0103] Reference Figure 3 As shown, when the detection device is placed on the first test platform 100, if the lower probe 320 comes into contact with the first test platform 100, the pressure sensor can detect that the lower probe 320 has a certain pressure value. Conversely, if the lower probe 320 does not come into contact with the first test platform 100, the pressure sensor will not detect the pressure value of the lower probe 320.

[0104] Therefore, in an example scenario, when the detection device is freely placed on the first platform 100 to be tested, if there is a recessed area at a certain location on the surface of the first platform 100 to be tested, the lower probe 320 end at that recessed area will not directly contact the platform surface, thus the pressure sensor will detect that the pressure information of the lower probe 320 is zero. Based on this principle, the surface flatness of the first platform 100 to be tested can be detected. The following section combines... Figure 4 The implementation method describes the detection method of this platform.

[0105] like Figure 4 As shown, in some embodiments, the platform detection method of this disclosure includes:

[0106] S410. When the detection device is freely placed on the first platform to be detected, the first pressure information of each lower probe is obtained.

[0107] S420. Based on the first pressure information and the difference between the pose information and the target pose, control the extension and retraction of each lower probe to contact the surface of the first test platform until the pose information is consistent with the target pose, and determine the extension and retraction data of the lower probe.

[0108] like Figure 5 As shown, in some example scenarios, the first platform 100 to be tested not only has a deflection angle error relative to the horizontal plane, but also a surface unevenness error. In this embodiment of the present disclosure, the detection device and detection method can simultaneously detect both the deflection angle and the unevenness.

[0109] In some embodiments, when the detection device is freely placed on the first detection platform 100, based on the foregoing, the current pose information can be acquired by the gyroscope inside the body 310. Simultaneously, pressure information of each lower probe 320, i.e., the first pressure information described in this disclosure, can also be acquired by the pressure sensor inside the body 310.

[0110] For example Figure 5 As shown in (a), when the detection device is placed freely, the lower probe tip located in the recessed area will not come into contact with the platform surface due to the presence of a recessed area on the platform surface. As a result, the pressure information of the lower probe 320 at that location detected by the pressure sensor is zero.

[0111] When the detection device adjusts the position of the main body 310 by extending and retracting the lower probe 320, it simultaneously controls the lower probe 320, whose pressure information is zero, to extend until the end of the lower probe 320 comes into contact with the platform surface. For example Figure 5 As shown in (b), while ensuring that the pose of the body 310 is consistent with the pose of the target, it is also necessary to make each lower probe 320 contact the surface of the first test platform 100.

[0112] In this embodiment of the disclosure, after the pose of the body 310 is adjusted to the target pose and each lower probe 320 is in contact with the platform surface, the extension and retraction of each lower probe 320 is locked, and the first extension and retraction data is determined based on the extension and retraction data of the lower probe 320 at this time.

[0113] It is understood that in this embodiment, the first extension data includes not only a representation of the deflection angle pose of the first platform 100 to be tested, but also a representation of the surface flatness of the first platform 100 to be tested. Therefore, after determining the first extension data, the detection result for the first platform 100 to be tested can be determined based on the first extension data. That is, the detection result includes both the deflection angle error result and the flatness error result of the first platform 100 to be tested.

[0114] As can be seen from the above, in this embodiment of the invention, the detection device can simultaneously detect the platform deflection angle and surface flatness, simplifying the platform detection process. Moreover, compared with pressure-sensitive paper, it can obtain more accurate surface flatness detection results, thereby improving the platform detection accuracy and detection effect.

[0115] For mechanical pressing equipment, it is necessary to inspect not only the lower platform but also the upper platform. For example... Figure 6 As shown, the pressing equipment generally includes a lower platform 10 and an upper platform 20, which can be driven to move relative to each other. The product 30 to be pressed can be placed on the surface of the lower platform 10, and the upper platform 20 is driven to press down with a preset pressure, thereby realizing the pressing of the product 30 to be pressed.

[0116] In some embodiments of this disclosure, the detection device can not only detect the lower platform 10 of the pressing equipment, but also simultaneously detect the upper platform 20 of the pressing equipment. The following describes... Figure 7 The implementation method is described below.

[0117] like Figure 7 As shown, in some embodiments, the platform detection apparatus of this disclosure includes not only the aforementioned lower probe 320, but also an upper probe 330. The upper probes 330 are distributed on the upper surface of the body 310, and the root of each upper probe 330 is connected to the body 310 via a driving device, so that each upper probe 330 can be driven to extend and retract in a direction perpendicular to the upper surface.

[0118] In this embodiment of the disclosure, the detection end of the pressure sensor is also connected to each upper probe 330, so that pressure information of each upper probe 330 can be collected and detected, and the controller can control the extension and retraction of the upper probe 330 according to the pressure information.

[0119] When inspecting the upper platform of the pressing equipment, the inspection device can be placed between the upper and lower platforms. The inspection of the lower platform is the same as described above. Figures 2 to 5The implementation method is the same. After determining the detection result of the lower platform, the upper platform can be used to press down the detection device with a preset pressure. The upper probe 330 is controlled to extend and retract according to the pressure information of the upper probe 330 to obtain the second pressure information and the second extension and retraction data of the upper probe. The detection result for the upper platform is determined based on the second pressure information and the second extension and retraction data. The following is combined with Figure 8 The implementation method is described in detail.

[0120] like Figure 8 As shown, in some embodiments, the platform detection method of this disclosure, after obtaining the detection result of the first platform to be detected, further includes:

[0121] S810. When the second platform to be tested is pressed against the testing device with a preset pressure, the second pressure information of the upper probe of the testing device is obtained.

[0122] like Figure 9 As shown in this embodiment, the first testing platform 100 is the lower platform of the pressing device, and the second testing platform 200 is the upper platform of the pressing device. The process for determining the testing result of the first testing platform 100 is described above by those skilled in the art. Figures 2 to 5 Any implementation method is acceptable, and this disclosure will not elaborate further.

[0123] After obtaining the test results of the first test platform 100, the second test platform 200 can be controlled to press the test device with a preset pressure. The preset pressure can be the pressure applied by the pressing equipment when pressing the product to be pressed. Those skilled in the art can set it according to the specific application scenario, and this disclosure does not limit it.

[0124] It is understandable that when the second testing platform 200 is pressed against the testing device, the pressure sensor of the testing device can acquire the pressure information at each position of the upper probe 330, that is, the second pressure information, which represents the pressure distribution information of the testing device. For example Figure 9 The second pressure information in the implementation method can be as follows: Figure 10 As shown, Figure 10 Each circle represents an upper probe 330, and the value in the circle represents the pressure value at the location of that upper probe 330.

[0125] For example Figure 9 As shown in (a), the second test platform 200 has a tilt angle deviation. From left to right in the figure, the contact between the upper probe 330 and the second test platform 200 decreases. Therefore, when the test device is pressed against the second test platform 200 with a preset pressure, the pressure on the left side of the figure is greater than the pressure on the right side. Figure 10As shown, the pressure distribution gradually decreases from left to right. That is, in this embodiment, the second pressure information can reflect the deflection angle error information of the upper platform.

[0126] S820: Based on the second pressure information, control the extension and retraction of the upper probe to make contact with the surface of the second test platform, and determine the second extension and retraction data of the upper probe.

[0127] like Figure 9 As shown in (a), in this example, due to the deflection angle error and surface flatness error of the second platform 200 to be tested, when the second platform 200 to be tested is pressed against the testing device, on the one hand, the forces on each upper probe 330 are uneven, and on the other hand, since some upper probes 330 do not directly contact the second platform 200 to be tested, the pressure information at that location is zero. In this embodiment of the present disclosure, the upper probes 330 with zero pressure information can be controlled to extend and retract, so that their ends come into contact with the surface of the second platform 200 to be tested, and the second extension and retraction data of the upper probes can be obtained. The following is in conjunction with Figure 11 Please provide an explanation.

[0128] like Figure 11 As shown, in some embodiments, the platform detection method of this disclosure, in the process of determining the second scaling data, includes:

[0129] S821. Identify each upper probe whose pressure is zero in the second pressure information.

[0130] S822, Control the extension and retraction of each upper probe with zero pressure, so that it comes into contact with the surface of the second test platform, and determine the second extension and retraction data of the upper probe.

[0131] like Figure 9 and Figure 10 As shown, there is a region with zero pressure in the second pressure information. As mentioned above, the position with zero pressure indicates that the upper probe 330 is not in direct contact with the surface of the second test platform 200.

[0132] For example Figure 10 As shown, the pressure values ​​at the two probe positions in the upper right corner are zero, and the second pressure information distribution conforms to the principle that the pressure values ​​decrease sequentially from left to right and from bottom to top. This indicates that the upper probe 330 is not in contact with the platform surface due to a deflection angle error in the second test platform 200. And for... Figure 10 The probe position in the 4th row and 2nd column of the second pressure information distribution shown has a pressure value of zero, but it does not conform to the pressure change pattern. Therefore, the upper probe 330 is not in contact with the platform surface because there is a concave area in the second test platform 200.

[0133] This example demonstrates that the second pressure information distribution can simultaneously represent the deflection angle error and surface flatness of the second platform under test.

[0134] In this embodiment of the disclosure, the upper probe 330 with a pressure value of zero can be controlled to extend and retract, so that it comes into contact with the surface of the second test platform 200. Then, the extension and retraction of each upper probe 330 is locked to obtain the extension and retraction data of each upper probe 330, which is the second extension and retraction data described in this disclosure.

[0135] S830. Based on the second pressure information and the second extension data, determine the test result of the second platform to be tested.

[0136] As described above, the second pressure information can reflect the deflection angle error and surface flatness of the second test platform 200, while the second extension data can also simulate the surface shape of the second test platform 200 using the extension and retraction of the upper probe 330. Therefore, in this embodiment, by combining the second pressure information and the second extension data, the test result of the second test platform can be determined, which simultaneously includes the deflection angle test result and the surface flatness test result of the second test platform 200.

[0137] As described above, in this embodiment, the detection device can simultaneously detect the deflection angle error and surface flatness of the two platforms of the pressing equipment, eliminating the need for separate detections and simplifying the pressing equipment inspection process. Furthermore, the pressure sensor can accurately quantify the stress on each part of the pressing equipment, unaffected by human factors, thus improving detection accuracy.

[0138] In some implementations, in conjunction with the foregoing Figure 5 As shown, the upper surface of some products 30 to be pressed is not flat. For example, some curved screen mobile phone screen modules have curved edges. In order to ensure the pressing effect of the curved areas, the force uniformity between the curved areas and the flat areas should be ensured. Therefore, in this embodiment, the upper probe 330 of the detection device can be used to simulate the upper surface of the product to be pressed, thereby enabling more accurate detection of the pressure uniformity of the pressing equipment.

[0139] like Figure 12 As shown, in some embodiments, the platform testing method of this disclosure, before pressing the testing device with the second platform to be tested, further includes:

[0140] S1210. Obtain the shape data of the product to be pressed.

[0141] S1220. Control the extension and retraction of the upper probe according to the shape data so that the end distribution of the upper probe is consistent with the shape of the product to be pressed.

[0142] Specifically, before the production of the product to be pressed, the shape data of the product to be pressed and the pressing data during the pressing process are determined in advance. The shape data may include, for example, the external dimensions of the product to be pressed, and the pressing data may include, for example, the preset pressure of the product to be pressed.

[0143] In this embodiment of the disclosure, the shape data of the product to be pressed can be obtained, and the extension and retraction of the upper probe 330 can be controlled according to the shape data so that the end distribution of the upper probe 330 is consistent with or approximately consistent with the shape of the upper surface of the product to be pressed.

[0144] In one example, such as Figure 13 As shown in (a), the dashed line represents the shape of the product 30 to be pressed. In this example, the upper surface of the product 30 to be pressed is a plane, thereby controlling the extension and retraction length of each upper probe 330 to be consistent, so that the ends of the multiple upper probes 330 are distributed to form a planar structure.

[0145] In another example, such as Figure 13 As shown in (b), the dashed line represents the shape of the product 30 to be pressed. In this example, the upper surface of the product to be pressed is curved, thereby controlling the extension and retraction of each upper probe 330, so that the ends of the multiple upper probes 330 are distributed to form a curved structure consistent with the upper surface of the product to be pressed.

[0146] Of course, it is understood that the shape of the product to be pressed is not limited to the above examples, but can be any other shape structure suitable for implementation, and this disclosure does not limit it.

[0147] As can be seen from the above, in this embodiment of the present disclosure, the detection device can be used to realize the simulated pressing detection of any product shape, improve the versatility of the detection method, simplify the detection process, and improve the detection accuracy.

[0148] In some implementations, considering that different products have different accuracy requirements, after determining the test results using the platform detection method disclosed herein, it can be determined whether to correct or adjust the platform based on the magnitude of the error in the test results.

[0149] Specifically, in some implementations, the platform detection method of this disclosure further includes:

[0150] In response to the fact that the detection results of the first platform to be tested and / or the second platform to be tested meet the preset conditions, the first platform to be tested and / or the second platform to be tested are adjusted based on the detection results.

[0151] In some implementations, preset thresholds can be set for the flatness and / or deflection angle of the platform surface. It can be understood that the preset threshold represents a critical value at which the platform error exceeds the required standard. After determining the platform's detection results, if the deflection angle error and / or surface flatness error of the detection results are not less than the preset threshold, it indicates that the platform's errors cannot meet production requirements, and the platform can be corrected and adjusted based on the deflection angle error and / or surface flatness error of the detection results. Conversely, if the deflection angle error and surface flatness error of the detection results are less than the preset threshold, it indicates that the platform's errors are small enough to meet production requirements, and no correction or adjustment of the platform is necessary.

[0152] As described above, in this embodiment, the lower probe of the detection device simulates the posture of the first platform to be tested, automatically detecting the error of the platform's deflection angle. The operation is simple, and the detection device has a simple structure, high detection accuracy, and improves the platform detection effect. The detection device can simultaneously detect the platform's deflection angle and surface flatness, simplifying the platform detection process. Compared to pressure-sensitive paper, it can obtain more accurate surface flatness detection results, improving the platform detection accuracy and effect. The detection device can simultaneously detect the deflection angle error and surface flatness of both platforms of the pressing equipment, eliminating the need for separate detection and simplifying the pressing equipment detection process. Furthermore, the pressure sensor can accurately quantify the force on each part of the pressing equipment, unaffected by human factors, thus improving detection accuracy.

[0156] Processor 301 can be any type of processor with one or more processing cores. It can perform single-threaded or multi-threaded operations, used for parsing instructions to perform operations such as acquiring data, performing logical operations, and sending out processing results.

[0157] The memory 302 may include a non-volatile computer-readable storage medium, such as at least one disk storage device, flash memory device, distributed storage device remotely located relative to the processor 301, or other non-volatile solid-state storage device. The memory may have a program storage area for storing non-volatile software programs, non-volatile computer-executable programs, and modules, which can be invoked by the processor 301 to cause the processor 301 to execute one or more of the following method steps. The memory 302 may also include a volatile random access storage medium, or a storage portion such as a hard disk, as a data storage area for storing the processing results and data output by the processor 301.

[0158] Pressure sensor 304 can be disposed at the root of each detection probe 306, so as to collect pressure information of the detection probe in real time when the detection probe 306 is subjected to external pressure. In some embodiments, pressure sensor 304 can be a thin-film pressure sensor of, for example, 0.35mm to 0.4mm.

[0159] The gyroscope 305 can be installed inside the body 310. After calibration, the gyroscope 305 can obtain the corresponding pose information in real time according to the pose change of the body 310, that is, the pose information of the detection device described below in this disclosure.

[0160] The detection probe 306 may include the lower probe 320 and / or upper probe 330 described in any of the above embodiments. Each detection probe 306 is provided with a driving device between itself and the body 310, so that the processor 301 can independently control the extension and retraction of each detection probe 306 by controlling the driving device.

[0165] The first determining module 103 is configured to determine the detection result of the first platform to be tested based on the first scaling data.
