[0028] See also Figure 1 , Figure 1 It is a structural diagram of an embodiment of the testing device provided by this application.

[0029] This application provides a testing device. Figure 1 and Figure 2 As shown, the testing device of this embodiment includes: a base 10, a carrying platform 20, a sensing module 30, and an information acquisition module 40. The carrying platform 20 is spaced apart from and opposite to the base 10. The end surface of the carrying platform 20 away from the base 10 is used to place the device to be tested 70. The sensing module 30 is arranged at the edge of the carrying platform 20. One end of the sensing module 30 is connected to the carrying platform 20, and the other end of the sensing module 30 is connected to the base 10. The information acquisition module 40 is coupled to the sensing module 30. The sensing module 30 is configured to detect the pressure generated when the carrying platform 20 vibrates and squeezes the sensing module 30 when the device to be tested 70 is working. The information acquisition module 40 determines the degree of vibration of the device to be tested 70 in different directions based on the pressure generated by the sensing module 30. The information acquisition module 40 can be a computer or a mobile device to collect the pressure exerted on the sensing module 30, or it can be a collection device integrated inside the base 10. Among them, the method of judging the vibration degree of the device under test 70 in different directions can be expressed as judging the vibration amplitude and frequency of the device under test 70 in different directions, etc., which can be set specifically according to needs and is not limited in this application.

[0030] In an optional embodiment, the base 10 can be placed on a horizontal bottom surface, that is, the flat base 10 is used to increase the accuracy of subsequent testing devices during testing. A supporting platform 20 is provided on the base 10, and the supporting platform 20 is spaced apart from the base 10, and the supporting platform 20 is arranged opposite to the base 10, that is, the supporting platform 20 can vibrate on the base 10, that is, when the device to be tested 70 is inspected, the vibration of the device to be tested 70 will drive the supporting platform 20 to vibrate. Among them, when the supporting platform 20 vibrates, it is represented by the edge position of the supporting platform 20 jumping up and down relative to the plane where the end face of the base 10 is located, that is, when the device to be tested 70 is tested, the vibration of the device to be tested 70 is started, thereby driving the supporting platform 20 to vibrate on the base 10.

[0031] In some embodiments, a sensing module 30 is disposed at the edge of the support platform 20. One end of the sensing module 30 is connected to the support platform 20, and the other end is connected to the base 10. That is, the sensing module 30 is disposed on the end surface of the base 10 opposite the support platform 20. The sensing module 30 can detect the pressure applied to it, that is, when the support platform 20 vibrates, the support platform 20 squeezes the sensing module 30.

[0032] In this embodiment, the testing device further includes an information acquisition module 40, which is coupled to the sensing module 30. The information acquisition module 40 can detect the pressure generated when the sensing module 30 is squeezed by the support platform 20. Specifically, when the device under test 70 is operating, the vibration of the device under test 70 causes the support platform 20 to vibrate, and the vibration of the support platform 20 squeezes the sensing module 30. The squeezing of the sensing module 30 generates a corresponding pressure value, which is transmitted to the information acquisition module 40. The information acquisition module 40 then determines the vibration amplitude of the device under test 70 based on this pressure value.

[0033] Among them, the sensing module 30 is arranged at the edge of the carrier platform 20. After the device to be tested 70 is placed on the carrier platform 20, the sensing module 30 detects the pressure values of the carrier platform 20 in different directions, and transmits the corresponding pressure values to the information acquisition module 40 after detecting them, so as to judge whether the carrier platform 20 is in a parallel state relative to the base 10, that is, before testing the device to be tested 70, the end face of the carrier platform 20 is parallel to the end face of the base 10, thereby avoiding the weight of the carrier platform 20 squeezing the sensing module 30 when the device to be tested is tested subsequently, thereby affecting the test results.

[0034] In some embodiments, the sensing module 30 is disposed at an edge of the platform 20. Specifically, the sensing module 30 can be disposed around the edge of the platform 20 to facilitate detection of the vibration level of the platform 20 in various directions. When the device 70 to be tested is being tested, the vibration of the device 70 will cause the platform 20 to vibrate. When the platform 20 vibrates, the sensing modules 30 at different positions on the platform 20 can detect the pressure generated when the platform 20 squeezes the sensing modules 30. The information acquisition module 40 receives the pressure value transmitted by the sensing module 30 and determines the pressure applied by the platform 20 to the sensing module 30 based on the pressure, thereby determining the vibration level of the device 70 to be tested. Specifically, because the sensing module 30 is disposed at the edge of the platform 20, that is, when the platform 20 vibrates, the sensing module 30 can detect the pressure applied by the platform 20 to the sensing module 30 in various directions, thereby determining the vibration level of the device 70 to be tested in different directions.

[0035] In a specific application scenario, when testing the module device 70 to be tested, the device to be tested 70 is first fixed at the center of the carrier 20, and the sensing module 30 detects the pressure generated by the carrier 20 squeezing the sensing module 30. If the sensing module 30 in one direction of the carrier 20 detects pressure, the information acquisition module 40 can determine that the carrier 20 is in a tilted state based on the pressure, and can balance the weight in the other direction of the carrier 20 according to the corresponding pressure until the sensing module 30 on the carrier 20 completely detects no pressure, thereby making the carrier 20 in a balanced state. For example, after the device to be tested 70 is fixedly placed on the carrier 20, the sensing module 30 in the first direction is squeezed by the carrier 20, and it can be determined that the carrier 20 is tilted toward the first direction. At this time, a weight can be placed on the carrier 20 in the direction opposite to the first direction to balance the carrier 20. After the supporting platform 20 is balanced, that is, after the end face of the supporting platform 20 is parallel to the end face of the base 10, the device to be tested 70 can be started. When the device to be tested 70 is working, it will generate vibration to drive the supporting platform 20 to vibrate. When the supporting platform 20 vibrates, the sensing module 30 at the edge of the supporting platform 20 can be squeezed. The sensing module 30 is squeezed by the supporting platform 20 to obtain the squeezed pressure value and transmit it to the information acquisition module 40. Based on the above pressure value, the information acquisition module 40 determines the vibration degree of the supporting platform 20 in different directions, thereby determining the vibration degree of the device to be tested 70 in different directions.

[0036] Among them, based on the accuracy of obtaining the vibration degree of the device to be tested 70 in different directions, the sensing module 30 can be evenly arranged on the end surface of the supporting platform 20 facing the base 10, so that when the sensing module 30 detects pressure, it can effectively ensure that the vibration degree of the device to be tested 70 in various directions is obtained, so that based on the vibration degree, the device to be tested 70 can be calibrated in a targeted manner.

[0037] In the above embodiment, by arranging the supporting platform 20 at intervals and relative to each other on the base 10, and arranging the sensing module 30 connected to the base 10 at the edge of the supporting platform 20, when the device to be tested 70 is tested, the device to be tested 70 will drive the supporting platform 20 to vibrate, and the sensing module 30 detects the pressure generated by squeezing the sensing module 30 when the supporting platform 20 vibrates. The information acquisition module 40 judges the vibration degree of the device to be tested 70 in different directions based on the pressure exerted on the sensing module 30, and can quickly and conveniently detect the vibration degree of the device to be tested 70. Moreover, the sensing modules 30 are distributed on the supporting platform 20, and can accurately detect the vibration degree of the device to be tested 70.

[0038] In an optional embodiment, if Figure 2 As shown, the sensing module 30 includes multiple vibration detection modules 31, wherein the multiple vibration detection modules 30 can be dispersedly arranged at the edge positions of the support platform 20. That is, the vibration detection modules 31 are used to detect the vibration degree of the support platform 20 in different directions when the device under test 70 vibrates. Specifically, the vibration of the device under test 70 drives the support platform 20 to vibrate, and the support platform 20 will squeeze the vibration detection module 31. The vibration detection module 31 obtains the pressure value of the support platform 20 and transmits it to the information acquisition module 40. The information acquisition module 40 receives the pressure value and determines the vibration degree of the device under test 70 in different directions.

[0039] Among them, the vibration detection modules 31 are evenly distributed at the edge positions of the supporting platform 20, that is, vibration detection modules 31 are arranged around the edge positions of the supporting platform 20. When the vibration of the device to be tested 70 drives the supporting platform 20 to vibrate, the vibration degree of the edge positions of the supporting platform 20 can be obtained more accurately, thereby obtaining the vibration degree of the device to be tested 70 in all directions.

[0040] In this embodiment, if Figure 3 and Figure 4As shown, the vibration detection module 31 includes: a first pressure sensor 311, a protective member 312, a first elastic member 313 and a buffer member 314. The first pressure sensor 311 is arranged on the end face of the supporting platform 20 facing the base 10, and the end face of the base 10 opposite to the first pressure sensor 311 is correspondingly provided with a protective member 312, wherein the protective member 312 is an annular cylindrical shape. The first elastic member 313 passes through the protective member 312 and is connected to the first pressure sensor 311 and the base 10; the buffer member 314 is arranged on the end face of the side opposite to the protective member 312. That is, when the supporting platform 20 vibrates, the supporting platform 20 will squeeze the first elastic member 313. After the first elastic member 313 is squeezed, the elastic force of the first elastic member 313 acts on the first pressure sensor 311, thereby obtaining the pressure when the supporting platform 20 squeezes the first elastic member 313 when it vibrates. After detecting the pressure applied by the platform 20 during compression, the first pressure sensor 311 transmits the pressure to the information acquisition module 40. Based on this pressure, the information acquisition module 40 determines the vibration level of the device under test 70 in various directions. The first pressure sensor 311 can be embedded in the end face of the platform 20 facing the base 10. Specifically, the end face of the first pressure sensor 311 is flush with the end face of the platform 20 and is located within the platform 20, effectively reducing the space occupied by the test device.

[0041] In some embodiments, the first pressure sensor 311 is arranged on the supporting platform 20, one end of the first elastic member 313 is connected to the first pressure sensor 311, and the other end is connected to the base 10. When the supporting platform 20 vibrates, the first elastic member 313, the first pressure sensor 311 and the information acquisition module 40 cooperate to obtain the vibration degree of the supporting platform 20, so as to obtain the vibration degree of the device to be tested 70 on the supporting platform 20.

[0042] When testing the device 70 to be tested, the first elastic member 313 is repeatedly squeezed by the support platform 20 due to vibration. To prevent the first elastic member 313 from bending, a protective member 312 is provided on the outside of the first elastic member 313. The protective member 312 is divided into two parts: one connected to the end surface of the first pressure sensor 311 facing the base 10, and the other connected to the end surface of the base 10 facing the support platform 20. The protective member 312 is annular and cylindrical, that is, the protective member 312 is hollow. The first elastic member 313 is disposed between the two protective members 312 and penetrates the protective members 312. In other words, when the first elastic member 313 is squeezed and compressed, the protective member 312 can prevent the first elastic member 313 from bending.

[0043] In this embodiment, two protective members 312 are spaced apart. Specifically, one protective member 312 is fixedly mounted on the first pressure sensor 311 of the platform 20, while the other protective member 312 is fixedly mounted on the base 10. The two protective members 312 are coaxially arranged, effectively limiting the extension and retraction direction of the first elastic member 313 and preventing the first elastic member 313 from bending. The spacing between the two protective members 312 is determined by the maximum vibration level of the device under test 70. Specifically, when the device under test 70 vibrates, the platform 20 vibrates. The distance between the edge of the platform 20 and the base 10 varies during vibration. At the maximum vibration level of the device under test 70, i.e., when the distance between the edge of the platform 20 and the base 10 is closest, the two protective members 312 may contact each other, thereby protecting the first elastic member 313 and the first pressure sensor 311. This prevents excessive vibration during testing, which could cause the platform 20 to over-compress the first elastic member 313 and the first pressure sensor 311.

[0044] To prevent damage from collision between the two protective members 312, buffer members 314 are provided on opposite end surfaces of the protective members 312. This means that when the two protective members 312 collide, the buffer members 314 provide cushioning, thereby preventing damage to the protective members 312. The buffer members 314 may be rubber pads or other materials, and this application does not impose any specific restrictions thereon.

[0045] In other embodiments, the first pressure sensor 311 may also be disposed on the end surface of the base 10 facing the support platform 20. In this case, one end of the first elastic member 313 is connected to the end surface of the first pressure sensor 311 facing the support platform 20, and the other end is connected to the end surface of the support platform 20. The protective member 312 is disposed on the end surface of the support platform 20 opposite the first pressure sensor 311. Specific limitations may be imposed based on actual needs and are not specifically defined in this application.

[0046] In a specific application scenario, when testing the device under test 70, the vibration of the device under test 70 drives the support platform 20 to vibrate. The edge of the support platform 20 squeezes the first elastic member 313. The elastic force generated by the squeezing of the first elastic member 313 squeezes the first pressure sensor 311. The first pressure sensor 311 can transmit the elastic force of the first elastic member 313 to the information acquisition module 40. The force exerted by the first elastic member 313 on the first pressure sensor 311 is the pressure exerted by the support platform 20 on the first elastic member 313. After the elastic force of the first elastic member 313 is transmitted to the information acquisition module 40, the information acquisition module 40 can determine the degree of vibration of the support platform 20 in different directions based on this elastic force, thereby determining the degree of vibration of the device under test in different directions.

[0047] It should be noted that when testing the device under test 70, the device under test 70 is fixedly placed on the support platform 20. That is, the greater the vibration of the device under test 70, the greater the vibration of the support platform 20. The greater the vibration of the support platform 20, the greater the deformation of the first elastic member 313 due to compression, and the greater the elastic force exerted by the first elastic member 313 on the first pressure sensor 311. In other words, the pressure detected by the first pressure sensor 311 is positively correlated with the deformation of the first elastic member 313, the vibration of the support platform 20, and the vibration of the device under test 70. Therefore, the information acquisition module 40 can obtain the vibration level of the device under test 70 based on the pressure of the first pressure sensor 311.

[0048] In some embodiments, the carrying platform 20 has a circular structure. A fixing member 60 is provided on the end surface of the central region of the carrying platform 20, away from the base 10. The fixing member 60 is used to secure the device under test 70. The circular structure of the carrying platform 20 ensures that when the device under test 70 drives the carrying platform 20 to vibrate, the edges of the carrying platform 20 are at the same distance from the center. This ensures that, even when the degree of vibration of the carrying platform 20 is the same in different directions, the pressure exerted on the first elastic member 313 by the edges of the carrying platform 20 is the same. This effectively improves the accuracy of the testing device when testing the device under test 70.

[0049] In this embodiment, if Figure 5 As shown, a fixture 60 is provided on the support platform 20. The fixture 60 can be provided in various shapes to accommodate different models of devices under test 70. Specifically, when testing different models of devices under test 70, a corresponding fixture 60 can be selected. The fixture 60 has a groove formed therein, and when securing the device under test 70, the device under test 70 can be fixed in the groove. The fixture 60 can also be provided in other shapes, which are not specifically limited in this application.

[0050] In some embodiments, a support member 50 is provided on the end surface of one side of the central region of the carrier platform 20 facing the base 10. The support member 50 is connected to the base 10, wherein the support member 50 is a soft pad. The carrier platform 20 is movably mounted on the support member 50, and the support member 50 is disposed at the center of the carrier platform 20, thereby spacing the carrier platform 20 on the base 10. When the device to be tested 70 vibrates, the carrier platform 20 can vibrate on the support member 50. In order to facilitate the vibration of the carrier platform 20 on the support member 50 and reduce the resistance during vibration, the support member 50 is configured as a soft pad, so that the carrier platform 20 can effectively vibrate on the support member 50.

[0051] The support member 50 can also be circular and positioned at the center of the platform 20. This means that the edges of the support member 50 are equidistant from the edges of the platform 20, and the perimeter of the support member 50 is equidistant from the perimeter of the platform 20. This allows the sensing module 30 to accurately detect the degree of vibration in different directions when the platform 20 vibrates. For example, if the vibration degree of the platform 20 is the same in different directions, the pressure exerted by the platform 20 on the vibration detection module 31 in different directions is the same.

[0052] In an optional embodiment, if Figure 5 As shown, the sensing module 30 also includes a plurality of bias modules 32, which are dispersedly arranged on the end surface of the supporting platform 20 facing the base 10, wherein the vibration detection module 31 is arranged at the edge of the supporting platform 20, and the projections of the plurality of bias modules 32 on the supporting platform 20 are completely located within the projections of the plurality of vibration detection modules 31 on the supporting platform 20, that is, the vibration detection module 31 is arranged around the supporting platform 20, and the distance between the plurality of bias modules 32 and the edge of the supporting platform 20 is greater than the distance between the vibration detection module 31 and the edge of the supporting platform 20.

[0053] In some embodiments, when testing the device to be tested 70, that is, after the device to be tested 70 is fixed on the carrier platform 20, the carrier platform 20 will tilt due to the different gravity of the device to be tested 70 on the carrier platform 20 in different directions. When the carrier platform 20 tilts, the bias module 32 can detect the pressure of the carrier platform 20 in a certain direction, and the information acquisition module 40 can obtain the pressure generated when the carrier platform 20 squeezes the bias module 32. Based on the pressure, it can be determined in which specific direction the carrier platform 20 is tilted, thereby facilitating the correction of the carrier platform 20.

[0054] In some embodiments, the bias module 32 includes a second elastic member 321 and a second pressure sensor 322. The second pressure sensor 322 is disposed on the base 10, and the second elastic member 321 is connected to the second pressure sensor 322 and the carrier 20. After the device under test 70 is fixed to the carrier 20 via the fixing member 60, the weight of the carrier 20 in different directions is different, causing the carrier 20 to tilt. After the carrier 20 tilts, the carrier 20 squeezes the second elastic member 321. After the second elastic member 321 is squeezed, the carrier 20 generates an elastic force, which acts on the second pressure sensor 322. The pressure detected by the second pressure sensor 322 is transmitted to the information acquisition module 40. The information acquisition module 40 can determine the tilt direction of the carrier 20 based on the pressure so as to correct the carrier 20, thereby facilitating subsequent testing of the device under test 70.

[0055] Among them, Figure 6 and Figure 7 As shown, the carrier 20 is provided with a plurality of holes 41, each of which can be used to place counterweights 42 to ensure the balance of the carrier 20. Specifically, after the device to be tested 70 is secured to the carrier 20 and the tilt direction of the carrier 20 is determined using the bias module 32, counterweights 42 can be placed in the holes 41, thereby calibrating the carrier 20. Specifically, the carrier 20 is provided with a plurality of holes 41, each of which can be used to place a counterweight 42. Therefore, when the carrier 20 tilts, the counterweight 42 can be placed in any hole 41, effectively improving the efficiency of the calibration of the carrier 20.

[0056] In some embodiments, the hole 41 on the support platform 20 may be provided with a thread, and a thread compatible with the thread is formed on the counterweight block 42. When the configuration block is fixed on the hole 41, the configuration block can be fixed on the hole 41, thereby avoiding the configuration block from detaching from the support platform 20 when the device to be tested 70 drives the support platform 20 to vibrate, resulting in inaccurate test results.

[0057] In other embodiments, the second pressure sensor 322 may be disposed on an end surface of the support platform 20 facing the base 10, with one end of the second elastic member 321 connected to the second pressure sensor 322 and the other end connected to the base 10. Furthermore, the second pressure sensor 322 may be embedded within the support platform 20, with its end surface flush with the end surface of the support platform 20. This is not limited in this application.

[0058] In some embodiments, a transmission element (not shown) is disposed within the base 10 and is connected to the first pressure sensor 311 and the second pressure sensor 322. The transmission element is also connected to the information acquisition module 40. The transmission element, which can be a circuit, is disposed within the base 10 to transmit the pressures detected by the first pressure sensor 311 and the second pressure sensor 322 to the information acquisition module 40. Placing the transmission element within the base 10 effectively reduces the volume occupied by the testing equipment.

[0059] The information acquisition module 40 is configured with a pressure threshold. The information acquisition module 40 is used to determine whether the first pressure value generated when the sensing module 30 detects vibration of the support platform 20 is greater than the pressure threshold, thereby filtering out useless data. Specifically, when the device under test 70 causes the support platform 20 to vibrate, the vibration level of the device under test 70 in some directions is small, meaning that the device under test 70 in these directions does not require correction. Therefore, a pressure threshold is configured within the information acquisition module 40. When the support platform 20 squeezes the vibration detection module 31 in areas where the device under test 70 is vibrating less, the pressure applied to the vibration detection module 31 is less than the pressure threshold, and this pressure value can be filtered out, thereby reducing the data processing load of the information acquisition module 40.

[0060] Specifically, when testing the device to be tested 70, the device to be tested 70 drives the support platform 20 to vibrate, and the vibration of the support platform 20 squeezes the first elastic member 313, which squeezes the first pressure sensor 311. After the first pressure sensor 311 is subjected to the elastic force of the first elastic member 313, the elastic force is transmitted to the information acquisition module 40. The information acquisition module 40 can process the pressure values transmitted by different first pressure sensors 311, record the pressure values greater than the pressure threshold, and record the position information of the first pressure sensor 311, and filter the pressure values less than the pressure threshold. In this way, the recorded data can be analyzed to accurately obtain the vibration degree of the device to be tested 70 in different directions.

[0061] See also Figure 8 , Figure 8 It is a flow chart of an embodiment of the test method of the present application. It should be noted that if there are substantially the same results, the method of the present invention is not used as Figure 8 The process sequence shown is limited. Figure 8 As shown, the method includes the following steps:

[0062] S11: The device to be tested 70 is placed and fixed on the supporting platform 20 .

[0063] When testing the device 70 to be tested, the fixture 60 is first fixed to the center of the platform 20. After the fixture 60 is fixed to the platform 20, the device 70 to be tested is then fixed to the fixture 60. Specifically, screws or latches can be used for fixing, and this application does not make specific restrictions here.

[0064] S12: Configuring the pressure threshold of the information collection module 40.

[0065] In some embodiments, the pressure threshold of the information acquisition module 40 is configured according to the model of the device to be tested 70 fixed on the support platform 20. For example, the vibration degree of some devices to be tested 70 is relatively large, and its pressure threshold can be set to be relatively large, so that the data whose pressure generated when the device to be tested 70 vibrates is less than the pressure threshold can be ignored, and the data whose pressure is greater than the pressure threshold is recorded.

[0066] S13 : The device under test 70 is started, and the sensing module 30 detects a first pressure value of the device under test 70 vibrating to drive the supporting platform 20 to press the sensing module 30 , and transmits the first pressure value to the information acquisition module 40 .

[0067] In this embodiment, the device to be tested 70 is inspected and started, and the device to be tested 70 drives the supporting platform 20 to vibrate. The vibration of the supporting platform 20 squeezes the sensing module 30. After the sensing module 30 is squeezed, a first pressure value is obtained and transmitted to the information acquisition module 40.

[0068] Specifically, the supporting platform 20 vibrates to squeeze the first elastic member 313. After being compressed, the first elastic member 313 squeezes the first pressure sensor 311. After being squeezed, the first pressure sensor 311 obtains a first pressure value and transmits the first pressure value to the information acquisition module 40 through the transmission member.

[0069] The first pressure sensor 311 transmits the elastic force of the first elastic member 313 to the information acquisition module 40 .

[0070] S14: The information acquisition module 40 compares the first pressure value with the pressure threshold to obtain a second pressure value exceeding the pressure threshold, and determines the vibration degree of the device under test 70 in different directions based on the second pressure value.

[0071] In this embodiment, if the first pressure value transmitted by the first pressure sensor 311 is greater than the pressure threshold, the information acquisition module 40 records it. If the first pressure value transmitted by the first pressure sensor 311 is less than the pressure threshold, the information acquisition module 40 filters it. That is, after receiving the first pressure value, the information acquisition module 40 compares the first pressure value with the pressure threshold to obtain a second pressure value that exceeds the pressure threshold, and obtains the vibration degree of the device under test 70 in different directions based on the second pressure value.

[0072] Please refer to Figure 9 , Figure 9 yes Figure 8 Specifically, the above-mentioned step S11 may further include the following steps:

[0073] S111 : The sensing module 30 obtains third pressure values of the supporting platform 20 in different directions and transmits the third pressure values to the information acquisition module 40 .

[0074] In this embodiment, after the device under test 70 is secured to the carrier 20, the carrier 20 compresses the sensing module 30 to obtain third pressure values of the carrier 20 in different directions. Specifically, the carrier 20 compresses the bias module 32, and the bias module 32 obtains the third pressure value when the carrier 20 compresses the bias module 32 and transmits it to the information acquisition module 40.

[0075] Specifically, after the device to be tested 70 is fixed on the supporting platform 20, the supporting platform 20 squeezes the second elastic member 321. The second elastic member 321 is compressed after being squeezed to act on the second pressure sensor 322. The second pressure sensor 322 obtains the third pressure value when the second elastic member 321 is squeezed, and transmits it to the information acquisition module 40 through the transmission member.

[0076] S112: The information acquisition module 40 determines whether the supporting platform 20 is balanced based on the third pressure value.

[0077] In this embodiment, after the information acquisition module 40 obtains the third pressure value, it can determine whether the support platform 20 is balanced based on the third pressure value. Specifically, if the third pressure value obtained by the information acquisition module 40 is 0, it can be determined that the support platform 20 is in a balanced state, that is, the support platform 20 is flush with the end surface of the base 10. If the third pressure value transmitted by the bias module 32 is greater than 0, it can be determined that the support platform 20 is in a tilted state.

[0078] S113 : If the carrying platform 20 is unbalanced, fix the counterweight 42 on the carrying platform 20 to balance the carrying platform 20 .

[0079] In this embodiment, when the information acquisition module 40 determines that the support platform 20 is unbalanced based on the third pressure value, that is, when the third pressure value is greater than 0, a counterweight block 42 can be configured on the hole 41 of the support platform 20 until the pressure values transmitted by the bias module 32 are all 0, that is, when the support platform 20 is balanced, the pressure threshold of the information acquisition module 40 can be configured.

[0080] S114 : If the supporting platform 20 is balanced, the step of configuring the pressure threshold of the information acquisition module 40 is executed.

[0081] In this embodiment, if the support platform 20 is balanced, the pressure threshold of the information acquisition module 40 can be configured, that is, the third pressure value transmitted by the bias module 32 is 0. At this time, there is no need to configure the counterweight block 42 at the hole 41 on the support platform 20, and the steps of configuring the pressure threshold of the information acquisition module 40 can be directly executed.

[0082] Different from the prior art, the present application discloses a testing method, which is based on the above-mentioned testing equipment. The device to be tested 70 is fixed on the supporting platform 20, and the supporting platform 20 is balanced by the bias module 32 and the counterweight block 42. After the supporting platform 20 is balanced, the pressure transmitted by the vibration detection module 31 is used to obtain the vibration degree of the device to be tested 70 in different directions, which can efficiently and accurately obtain the deficiencies of the device to be tested 70. Moreover, the testing in this way is easy to operate and effectively reduces the consumption of manpower and material resources.
