The hardness of the area to be tested can be determined by the pressure value detected by the pressure sensor. Based on this, the area to be tested can be the area of ​​the object to be tested. Since the distance between the front end of the multiple probes and the top of the housing is different, it is equivalent to the extension length of the multiple probes being different in the initial state. The hardness tomographic data of the area to be tested can be determined by the force on the different probes. The hardness tomographic data can characterize the hardness of each layer of the object to be tested, which is equivalent to effectively determining the hardness of each layer of the object to be tested, thereby improving the hardness detection effect.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0035] It should be noted that in all specific embodiments of this application, when processing data related to user identity or characteristics, such as user information, user behavior data, user historical data, and user location information, user permission or consent is obtained first. Furthermore, the collection, use, and processing of this data comply with relevant laws, regulations, and standards. In addition, when embodiments of this application require access to sensitive personal information of users, separate permission or consent from the user is obtained through pop-ups or redirection to confirmation pages. Only after obtaining the user's separate permission or consent is the necessary user-related data required for the proper functioning of these embodiments acquired.

[0036] Currently, traditional hardness testing devices measure hardness using indentation or scratch methods, which can only detect a single hardness value and cannot detect the complete hardness of the object being tested, resulting in poor hardness testing results.

[0037] To address the problem of not being able to detect the internal hardness of the object under test, this application provides a hardness testing device, system, method, electronic device, and storage medium. The hardness testing device includes: a housing with multiple through holes at its top; multiple pressure sensors disposed at the bottom of the housing near the through holes; and multiple detection components, each including a force transmitter and a probe elastically connected to the force transmitter. The force transmitter is disposed within the housing. The number of detection components matches the number of through holes. The tip of each probe passes through its corresponding matching through hole. The distance between the tips of the multiple probes and the top of the housing varies. The tips of the probes are used to move towards the area to be tested. The number of detection components matches the number of pressure sensors. Each force transmitter contacts its corresponding matching pressure sensor. Each force transmitter transmits the force on its corresponding probe to its corresponding matching pressure sensor to determine the hardness tomographic data of the area to be tested. According to the solution provided in the embodiments of this application, multiple detection components are set up. The force transmission element in the detection component is set inside the housing. The front end of the probe in the detection component passes through the through hole located at the top of the housing, which is equivalent to the probe's detection end being in an extended state. Moreover, the probe and the force transmission element are elastically connected. During the process of controlling the front end of the probe to move towards the area to be tested, when the probe contacts the area to be tested, the force on the probe will increase and gradually retract into the housing. The elastic force generated by the elastic connection between the probe and the force transmission element will gradually increase, and the pressure generated by the force transmission element on the pressure sensor will also gradually increase. It is equivalent to the force transmission element transmitting the force on the probe to its respective matched pressure sensor. The hardness of the area to be tested can be determined by the pressure value detected by the pressure sensor. Based on this, the area to be tested can be the area of ​​the object to be tested. Since the distance between the front end of the multiple probes and the top of the housing is different, it is equivalent to the extension length of the multiple probes being different in the initial state. The hardness tomographic data of the area to be tested can be determined by the force on the different probes. The hardness tomographic data can characterize the hardness of each layer of the object to be tested, which is equivalent to effectively determining the hardness of each layer of the object to be tested, thereby improving the hardness detection effect.

[0038] The hardness testing device, system, method, electronic device, and storage medium provided in the embodiments of this application are specifically described through the following embodiments. First, the hardness testing device in the embodiments of this application is described.

[0039] The embodiments of this application will be further described below with reference to the accompanying drawings.

[0040] Reference Figures 1 to 5 This invention provides a hardness testing device, comprising:

[0041] The housing 100 has a plurality of through holes 121 on its top.

[0042] Multiple pressure sensors 200 are disposed at the bottom of housing 100 and on the side near the through hole 121;

[0043] Multiple detection components 300 are provided, each including a force transmitter 310 and a probe 320 elastically connected to the force transmitter 310. The force transmitter 310 is disposed within the housing 100. The number of detection components 300 matches the number of through holes 121. The tip of each probe 320 passes through its respective matching through hole 121. The distance between the tip of the multiple probes 320 and the top of the housing 100 is different. The tip of the probe 320 is used to move toward the area to be tested. The number of detection components 300 matches the number of pressure sensors 200. Each force transmitter 310 contacts its respective matching pressure sensor 200. Each force transmitter 310 is used to transmit the force of its corresponding probe 320 to its respective matching pressure sensor 200 to determine the hardness tomographic data of the area to be tested.

[0044] Since the number of detection components 300 matches the number of vias 121, the probe 320 of each detection component 300 can pass through its matching via 121. Since the number of detection components 300 matches the number of pressure sensors 200, the force transmission element 310 of each detection component 300 can contact its matching pressure sensor 200.

[0045] Understandably, by setting multiple detection components 300, with the force transmission element 310 of each detection component 300 housed within the housing 100, and the tip of the probe 320 in the detection component 300 passing through the through hole 121 at the top of the housing 100, the probe 320 is essentially in an extended state. Furthermore, the probe 320 and the force transmission element 310 are elastically connected. During the movement of the probe 320's tip towards the area to be measured, when the probe 320 contacts the area, the force on the probe 320 increases, and it gradually retracts into the housing 100. The elastic force generated by the elastic connection between the probe 320 and the force transmission element 310 gradually increases, and the force transmission element 310 exerts pressure on the pressure sensor 200. The force gradually increases, which means that the force transmission component 310 can transmit the force on the probe 320 to its respective matched pressure sensor 200. The pressure value detected by the pressure sensor 200 can determine the hardness of the area to be tested. Based on this, the area to be tested can be the area of ​​the object to be tested. Since the distance between the front end of the multiple probes 320 and the top of the housing 100 is different, it means that the extension length of the multiple probes 320 in the initial state is different. The hardness tomographic data of the area to be tested can be determined by the force on the different probes 320. The hardness tomographic data can characterize the hardness of each layer of the object to be tested, which means that the hardness of each layer of the object to be tested can be effectively determined, thereby improving the hardness detection effect.

[0046] Specifically, the hardness testing device may include nine detection components, namely, nine probes 320 and force transmission elements 310. The top of the housing 100 is provided with nine through holes 121, and the bottom of the housing 100 and the side near the through holes 121 are provided with an array sensor composed of nine pressure sensors 200. The probes 320, the corresponding force transmission elements 310 and the corresponding pressure sensors 200 are sequentially located on the same straight line. The probes 320 can move along the straight line, thereby adjusting the pressure value detected by the pressure sensors 200.

[0047] Additionally, refer to again Figure 1 In one embodiment, the probes 320 are arranged in a preset order, and the difference between the front end of any two adjacent probes 320 and the top of the housing 100 is a preset tomographic spacing.

[0048] Understandably, setting the difference between the distances between the front ends of any two adjacent probes 320 and the top of the housing 100 as a fixed inter-sectional spacing can improve the determination efficiency of hardness tomography data. For example, setting the inter-sectional spacing to 0.5 mm means that as the detection component 300 continues to move towards the test area, when the pressure value detected by the first pressure sensor 200 increases, it can be determined that the displacement of the absolute position distance between the detection component 300 and the test area is 0. Whenever the pressure value detected by any pressure sensor 200 increases, it can be assumed that the displacement of the absolute position distance increases by 0.5 mm, which can quickly determine the absolute position distance of the detection component 300, thereby improving the determination efficiency of hardness tomography data.

[0049] Specifically, the front ends of each probe 320 can be located on the same conical spiral line, which is equivalent to the front ends of each probe 320 being arranged from high to low with the center as the starting point.

[0050] Additionally, refer to Figures 3 to 9 In one embodiment, the detection component 300 further includes a spring 330, and the probe 320 is provided with a boss 321 located inside the housing 100. One end of the spring 330 is elastically connected to the boss 321, and the other end of the spring 330 is elastically connected to the top of the force transmission member 310. The spring 330 is used to push the boss 321 to abut against the top of the housing 100. The spring 330 is also used to push the force transmission member 310 to abut against the corresponding pressure sensor 200. The top of the force transmission member 310 is provided with a through hole 311, and a cavity 312 is provided inside the force transmission member 310. The through hole 311 communicates with the cavity 312. The rear end of the probe 320 passes through the corresponding spring 330 and the matching through hole 311 in sequence.

[0051] It is understandable that by providing a boss 321 on the probe 320, the boss 321 can be annular and arranged along the circumference of the probe 320. The outer diameter of the boss 321 is larger than the inner diameter of the spring 330. One end of the spring 330 is elastically connected to the boss 321, and the other end of the spring 330 is elastically connected to the top of the force transmission member 310. The elastic connection between the probe 320 and the force transmission member 310 is achieved by providing the spring 330. The top of the force transmission member 310 is provided with… The force transmission component 310 has a cavity 312 inside the through hole 311. The through hole 311 communicates with the cavity 312. That is, the force transmission component 310 can be a hollow inner sleeve, and the end of the inner sleeve that contacts the spring 330 has a through hole 311. The diameter of the through hole 311 is larger than the diameter of the rear end of the probe 320. The rear end of the probe 320 can pass through the through hole 311 and be located in the cavity 312 of the force transmission component 310, thereby ensuring the stability of the probe 320 during movement.

[0052] Specifically, before the probe 320 moves, that is, before the probe 320 contacts the area to be measured, the spring 330 is in its initial state. At this time, the spring 330 is also compressed. Therefore, the spring 330 can push the force transmission member 310 to abut against the corresponding pressure sensor 200.

[0053] Additionally, refer to again Figure 3 and Figure 4 In one embodiment, the housing 100 includes an outer sleeve 110, a first cover 120, and a second cover 130. The first cover 120 is detachably mounted on one end of the outer sleeve 110, and the second cover 130 is detachably mounted on the other end of the outer sleeve 110. A through hole 121 is provided on the top of the first cover 120, and a pressure sensor 200 is provided on the side of the second cover 130 near the through hole 121. The outer sleeve 110 is provided with a plurality of channels 111, the number of channels 111 matching the number of through holes 121, and a force transmission element 310 is provided in the corresponding channel 111.

[0054] It is understandable that since the housing 100 includes an outer sleeve 110, a first cover 120 and a second cover 130, and both the first cover 120 and the second cover 130 can be detachably installed with the outer sleeve 110, it is convenient to disassemble and install the hardness testing device. When the force transmission component 310, the probe 320 or the pressure sensor 200 need to be replaced or adjusted, the hardness testing device can be quickly disassembled and installed for adjustment.

[0055] Specifically, the outer side of the outer sleeve 110 may be provided with a first slot and a second slot, the first cover 120 may be provided with a first buckle that engages with the first slot, and the first cover 120 may be provided with a second buckle that engages with the second slot.

[0056] This invention provides a hardness testing system, including at least one of the above-described hardness testing devices.

[0057] Understandably, each hardness testing device can effectively detect the hardness of each cross layer of the object under test. Therefore, a hardness testing system can accelerate the hardness testing efficiency of the object under test by setting up multiple hardness testing devices.

[0058] The hardness testing method in the embodiments of this application is described below.

[0059] The hardness testing method provided in this application embodiment can be applied to the hardness testing system described above. The hardness testing system may include a controller for executing the hardness testing method.

[0060] like Figure 10 As shown, Figure 10 This is a schematic flowchart of an optional hardness testing method provided in an embodiment of this application. The hardness testing method includes, but is not limited to, the following steps 1010 to 1040:

[0061] Step 1010: Obtain the distance between the front end of the probe corresponding to each pressure sensor and the top of the housing to obtain their respective extension length.

[0062] Step 1020: Control the tip of the probe to move toward the area to be measured. Whenever the pressure value detected by the pressure sensor increases, the pressure sensor with the increased pressure value is identified as the reference sensor.

[0063] Step 1030: Whenever a pressure sensor is determined as a reference sensor, the previous pressure sensor that was determined as a reference sensor is determined as the target sensor, the pressure value currently detected by the target sensor is determined as the fault pressure value, and the absolute positional distance between the detection component and the area to be measured is determined based on the extension length corresponding to the reference sensor and the maximum value among the various extension lengths.

[0064] The absolute position distance is determined by the extension length of the reference sensor and the maximum value among the extension lengths. For example, the extension lengths of the nine probes are 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 45 mm and 50 mm respectively. Assuming the extension length of the reference sensor is 40 mm and the maximum value among the extension lengths is 50 mm, by subtracting 40 mm from 50 mm, the absolute position distance between the detection component and the area to be measured can be determined to be 10 mm. As the probe tip moves toward the area to be measured, other absolute position distances can also be calculated in a similar way. Therefore, each absolute position distance corresponds to a tomographic location.

[0065] Step 1040: Determine the hardness tomography data of the area to be tested based on the fault pressure values ​​and the corresponding absolute positional distances.

[0066] Based on this, the probe tip in the detection assembly passes through a through-hole located at the top of the housing, which is equivalent to the probe's detection end being in an extended state. Since the distances between the tips of multiple probes and the top of the housing are different, the initial extension lengths of the multiple probes are also different, allowing the acquisition of the extension length corresponding to each pressure sensor. The probe and the force transmission element are elastically connected. During the movement of the probe tip towards the test area, when the probe is not in contact with the test area, the force on the probe does not increase. When the probe contacts the test area, the force on the probe increases and it gradually retracts into the housing. The elastic force generated by the elastic connection between the probe and the force transmission element gradually increases, and the pressure generated by the force transmission element on the pressure sensor also gradually increases. This means that the force transmission element can transmit the force on the probe to its respective matched pressure sensor. Therefore, whenever the pressure value detected by the pressure sensor increases, this pressure is transmitted... The sensor is designated as the reference sensor. Since the distance between the tip of multiple probes and the top of the housing is different, multiple probes contact the area to be tested sequentially. That is, multiple pressure sensors can be designated as reference sensors in turn. Therefore, whenever a pressure sensor is designated as a reference sensor, the previous pressure sensor designated as the reference sensor is designated as the target sensor. Then, the pressure value detected by the target sensor at the current time is recorded to obtain the tomographic pressure value. Furthermore, by using the corresponding extension length of the reference sensor and the maximum value among the extension lengths, the absolute positional distance between the detection component and the area to be tested can be determined. In addition, the hardness tomographic scan data of the area to be tested can be determined by using the tomographic pressure value and the absolute positional distance. The hardness tomographic scan data can characterize the hardness of each fracture of the test object, which is equivalent to effectively determining the hardness of each fracture of the test object, thereby improving the hardness detection effect.

[0067] Additionally, refer to Figure 11 In one embodiment, the hardness tomography data of the area to be tested is determined based on each fault pressure value and the corresponding absolute positional distance, including but not limited to the following steps:

[0068] Step 1110: At each absolute position distance, determine the fault hardness based on the corresponding fault pressure value and the corresponding initial pressure value, wherein the initial pressure value is the pressure value detected by the target sensor before the corresponding probe moves.

[0069] Step 1120: For each absolute position distance, determine the corresponding probe displacement distance based on the corresponding fault pressure value and the corresponding initial pressure value, and determine the fault deformation value based on the absolute position distance and the displacement distance.

[0070] Step 1130: Determine the hardness tomography data of the area to be tested based on the hardness of each fault and the corresponding fault deformation value.

[0071] Understandably, as the probe tip moves towards the test area, multiple absolute positional distances can be determined, each corresponding to a fault location. Before the probe moves, the spring is in its initial state, and is compressed. Therefore, the spring can push the force transmission component to contact the corresponding pressure sensor. The pressure value detected by the pressure sensor is used as the initial pressure value. At any fault location, the fault hardness can be calculated using the fault pressure value currently detected by the target sensor and the initial pressure value detected in the initial state. When the probe and the force transmission component are connected by a spring, the formula for calculating the fault hardness is as follows:

[0072] H A =(F-F0) / A

[0073] Among them, H A F is the fault hardness, F is the fault pressure value, F0 is the initial pressure value, and A is the preset hardness coefficient.

[0074] Then, since the displacement distance of the probe is equal to the change in the compression length of the spring, the change in the compression length of the spring can be calculated using the fault pressure value and the corresponding initial pressure value. This change in the compression length of the spring can then be used as the displacement distance of the probe. Therefore, the formula for calculating the displacement distance is as follows:

[0075] x=(F-F0) / k

[0076] Where x is the displacement distance, F is the fault pressure value, F0 is the initial pressure value, and k is the spring stiffness coefficient;

[0077] The fault deformation value can then be determined using the absolute positional distance and displacement distance. The formula for calculating the fault deformation value is as follows:

[0078] d=Lx

[0079] Where d is the fault deformation value, L is the absolute position distance, and x is the displacement distance;

[0080] Then, by using the hardness of each fault and the corresponding fault deformation value, the hardness tomography data of the area to be tested is determined. For example, a coordinate system of hardness tomography data with fault deformation value as the abscissa and fault hardness as the ordinate can be constructed, and the image of the hardness tomography data of the area to be tested can be drawn in this coordinate system.

[0081] Additionally, refer to Figure 12 In one embodiment, the test area is a region of the test object, which includes multiple test areas. The hardness testing method further includes, but is not limited to, the following steps:

[0082] Step 1210: Control the detection components to move toward other test areas where hardness tomography data has not been determined, and determine the hardness tomography data of each test area respectively.

[0083] Step 1220: Determine the scanning results of the test object based on the hardness tomography data.

[0084] It is understandable that the test object may include multiple test areas. A single hardness testing device can determine the hardness tomography data of a single test area in one round of testing. Therefore, by controlling the testing component to move towards other test areas where the hardness tomography data has not been determined, it is equivalent to performing a new round of testing. The hardness tomography data of other test areas are used, and then the scanning result of the test object is determined by summarizing all the hardness tomography data.

[0085] Additionally, refer to Figure 13 , Figure 13 The hardware structure of an electronic device according to another embodiment is illustrated. The electronic device includes:

When the technical solutions provided in the embodiments of this specification are implemented through software or firmware, the relevant program code is stored in the memory 1302 and called by the processor 1301 to execute the hardness detection method of the embodiments of this application, for example, executing the above-described...

[0091] The processor 1301, memory 1302, input / output interface 1303 and communication interface 1304 are connected to each other within the device via bus 1305.

[0092] This application embodiment also provides a storage medium, which is a computer-readable storage medium for computer-readable storage. The storage medium stores one or more programs, which can be executed by one or more processors to implement the above-described hardness detection method, for example, executing the above-described...

[0093] Memory, as a non-transitory computer-readable storage medium, can be used to store non-transitory software programs and non-transitory computer-executable programs. Furthermore, memory may include high-speed random access memory, and may also include non-transitory memory, such as at least one disk storage device, flash memory device, or other non-transitory solid-state storage device. In some embodiments, memory may optionally include memory remotely located relative to the processor, and these remote memories can be connected to the processor via a network. Examples of such networks include, but are not limited to, the Internet, intranets, local area networks, mobile communication networks, and combinations thereof.

[0094] The hardness testing device, system, method, electronic device, and storage medium provided in this application can be applied to scenarios where the hardness of the object to be tested is being tested. Based on this, multiple detection components are set up. The force transmission element in the detection component is set inside the housing. The tip of the probe in the detection component passes through a through hole located at the top of the housing, which is equivalent to the probe's detection end being in an extended state. Moreover, the probe and the force transmission element are elastically connected. During the process of controlling the tip of the probe to move towards the test area, when the probe contacts the test area, the force on the probe will increase and gradually retract into the housing. The elastic force generated by the elastic connection between the probe and the force transmission element will gradually increase, and the pressure generated by the force transmission element on the pressure sensor will also gradually increase. It is equivalent to the force transmission element transmitting the force on the probe to its respective matched pressure sensor. The pressure value detected by the pressure sensor can determine the hardness of the test area. Based on this, the test area can be the area of ​​the test object. Since the distance between the tip of the multiple probes and the top of the housing is different, it is equivalent to the extension length of the multiple probes being different in the initial state. The hardness tomographic data of the test area can be determined by the force on the different probes. The hardness tomographic data can characterize the hardness of each layer of the test object, which is equivalent to effectively determining the hardness of each layer of the test object, thereby improving the hardness detection effect.
