Description

Technical Field

[0001] This application relates to the field of vibration testing technology, and in particular to magnetic drive vibration testing systems, testing methods, electronic devices and storage media. Background Technology

[0002] During the production and processing of products or during subsequent transportation, vibrations caused by external forces are unavoidable. In order to further ensure product quality, vibration tests are usually conducted on the products during the production and processing to evaluate the performance changes of the products during vibration, so as to ensure that the products can be output after vibration to ensure normal working performance.

[0003] In related technologies, vibration testing during product manufacturing typically involves setting up a mechanical vibration table at a point on the transport line. Complex mechanical components are used to generate and control the vibration frequency and amplitude, thus inducing different degrees of vibration in the moving parts and enabling vibration detection of the product. However, due to hardware limitations, mechanical vibration tables can usually only provide a few fixed vibration levels for testing. Therefore, they cannot meet the high-precision vibration detection requirements for high-precision electronic components. Summary of the Invention

[0025] The static change time and fluctuation amplitude of the workpiece are obtained, and the vibration detection results are updated based on the static change time, the fluctuation amplitude, and the static magnetic levitation control parameters.

[0026] In some embodiments, the system is further provided with a detection sensor, which is connected to the control processor;

[0027] The detection sensor is used at least to acquire the location data and transmit the location data to the control processor.

[0028] In some embodiments, the system is provided with a detection platform at the detection station, and the detection platform is provided with an induction magnet.

[0046] 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.

[0047] It should be noted that although functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0049] During the production and processing of products or during subsequent transportation, vibrations caused by external forces are unavoidable. In order to further ensure product quality, vibration tests are usually conducted on the products during the production and processing to evaluate the performance changes of the products during vibration, so as to ensure that the products can be output after vibration to ensure normal working performance.

[0050] In related technologies, vibration testing during product manufacturing typically involves setting up a mechanical vibration table at a point on the transport line. Complex mechanical components are then used to generate and control the vibration frequency and amplitude, thus subjecting the moving part to different degrees of vibration for vibration testing. However, due to hardware limitations, mechanical vibration tables usually only offer a few fixed vibration levels for testing.

[0051] For testing electronic components with high precision requirements (such as smartphones, tablets, hard disk drives, miniature sensors, optical devices, microelectromechanical systems, precision mechanical components, integrated circuits, semiconductor chips, optical sensors, etc.), the requirements for vibration frequency and amplitude during the testing process are very strict, and mechanical vibration tables cannot meet the requirements for high-precision vibration testing.

[0052] Based on this, in order to meet the high-precision vibration detection requirements of electronic components, this application embodiment utilizes a magnetic drive device that can finely adjust the magnetic field changes to accurately change the force characteristics of the workpiece being tested. By precisely adjusting the control parameters of the electromagnetic coil, the output working magnetic field is precisely adjusted, thereby precisely adjusting the vibration frequency and vibration amplitude of the workpiece being tested at the testing station to meet the high-precision vibration detection requirements of the workpiece. Furthermore, the position data of the workpiece being tested during the vibration process is used to accurately obtain the vibration detection results of the workpiece being tested. Moreover, by using a simple magnetic drive device to replace the mechanical vibration table composed of complex mechanical parts, the setup cost and subsequent maintenance cost can be effectively reduced.

[0053] The magnetic drive vibration detection system, magnetic drive vibration detection method, electronic device, and storage medium provided in the embodiments of this application will be further described below. First, the magnetic drive conveying system provided in this application will be described. (Refer to...) Figure 1 This is a schematic diagram of the structure of a magnetic drive vibration detection system provided in an embodiment of this application. Figure 1 As shown, the magnetic drive vibration detection system 100 includes a control processor 110 and a magnetic drive vibration assembly 120. The control processor 110 is connected to the magnetic drive vibration assembly 120, which generates a magnetic field that acts on the detection station. The control processor 110 then controls the magnetic drive vibration assembly 120 to change the generated magnetic field (such as changing the intensity, frequency, direction, etc.) according to different requirements. The detection station is used to place the workpiece 200 that needs to be vibrated.

[0054] It is understood that the testing station is located at a position on one side of the magnetic drive vibration assembly 120. It can be a fixed position or a flexible position that moves with the position of the magnetic drive vibration assembly 120. In this embodiment, there is no limitation.

[0055] Reference Figure 2 This is a schematic diagram of the structure of a magnetic drive vibration assembly provided in an embodiment of this application. Figure 2As shown, the magnetic drive vibration assembly 120 includes at least a plurality of stators 121, with electromagnetic coils 122 wound around the stators 121. The electromagnetic coils 122 generate a magnetic field at the detection station when energized. Furthermore, the control processor 110 can directly adjust the control parameters of the current of the electromagnetic coils 122 when energized to change the magnetic field generated by the electromagnetic coils 122 at the detection station.

[0056] In addition, in order to meet the vibration detection requirements of different types of workpieces 200 (such as smartphones, tablets, hard disk drives, micro-sensors, optical devices, microelectromechanical systems, precision mechanical components, integrated circuits, semiconductor chips, optical sensors, etc.), it is necessary to ensure that the number of stators 121 with electromagnetic coils 122 wound on the magnetic drive vibration assembly 120 is sufficient to support a sufficient range of frequency and amplitude changes, thereby meeting the testing requirements of various workpieces 200.

[0057] In some embodiments, the magnetic drive vibration detection system 100 can be installed on a section of the magnetic drive conveyor line. Combined with the electromagnetic control characteristics of the magnetic drive conveyor line, the magnetic drive vibration detection system 100 can accurately measure various vibration parameters of the workpiece 200 (such as electronic components) being conveyed on the magnetic drive conveyor line. It is understood that the magnetic drive vibration detection system 100 can perform comprehensive vibration performance testing on the workpiece 200 without affecting the overall operation of the magnetic drive conveyor line.

[0058] Based on this, when the inspection workpiece 200 running on the magnetic drive conveyor line reaches the inspection station, by controlling the electromagnetic coil 122 of the magnetic drive vibration component 120, only the magnetic field at the inspection station can be changed, so that the inspection workpiece 200 at the inspection station vibrates to a corresponding degree, but the magnetic field in other places on the magnetic drive conveyor line will not be changed, so as not to affect the normal operation of other components on the magnetic drive conveyor line and avoid unnecessary vibration energy loss.

[0059] Understandably, on magnetic drive conveyor lines, the workpiece to be inspected is typically transported using a mover. When the mover reaches the inspection station, the magnetic field generated by the magnetic drive vibration assembly 120 causes both the mover and the workpiece 200 to vibrate together. Furthermore, since magnetic drive conveyor lines are inherently non-contact, meaning there is no physical contact between the mover and the stator, the vibration of the mover and workpiece 200 does not directly affect the stator of other components on the magnetic drive conveyor line. This means that when performing vibration testing on the workpiece 200 on a magnetic drive conveyor line equipped with the magnetic drive vibration detection system 100, the mover does not need to be disconnected from the stator and can complete the vibration detection process directly on the magnetic drive conveyor line. After the vibration detection is completed, the mover can continue running along the magnetic drive conveyor line, ensuring the efficient operation of the production line on the magnetic drive conveyor line.

[0060] Furthermore, stator coils on magnetic drive conveyor lines are typically used to provide a constant magnetic field to drive the mover along the track of the magnetic drive conveyor line. Their control focuses primarily on the speed and position of the mover, rather than frequent adjustments to the current or magnetic field. However, the electromagnetic coil 122 in the magnetic drive vibration assembly 120 is specifically designed for vibration detection. It can generate different vibration amplitudes and frequencies by precisely adjusting the current intensity and frequency to simulate vibration conditions under various environments. Therefore, the electromagnetic coil 122 in the magnetic drive vibration assembly 120 needs to possess extremely high control precision, be able to finely adjust the current to generate the required vibration characteristics, support rapid current changes to generate vibrations of various frequencies, and have a wide adjustment range, supporting current changes from low to high frequencies and the generation of vibration amplitudes from small to large.

[0061] In some embodiments, when the workpiece 200 is placed at the inspection station, the control processor 110 determines multiple different detection parameter types and detection parameter ranges corresponding to the different detection parameter types based on the workpiece type of the workpiece 200. Then, based on these detection parameter ranges and the coil parameters of the electromagnetic coil 122 in the magnetic drive vibration assembly 120, multiple corresponding control parameters are generated. These control parameters are then used to control the magnetic drive vibration assembly 120 to adjust the current of the electromagnetic coil 122, thereby indirectly controlling the magnetic field generated by the electromagnetic coil 122 to obtain a working magnetic field corresponding to the control parameters, used to change the vibration force on the workpiece 200 at the inspection station. The control parameters include the current intensity and frequency of the current in the electromagnetic coil 122, etc.

[0062] Reference Figure 3 This is a schematic diagram of a magnetic drive vibration detection system equipped with a detection sensor, provided in an embodiment of this application. Figure 3 As shown, the magnetic drive vibration detection system 100 is also equipped with at least one detection sensor 130, and the detection sensor 130 is connected to the control processor 110. When the workpiece 200 is subjected to vibration detection at the detection station, the detection sensor 130 is used to acquire relevant detection parameters of the workpiece 200 (such as position data, temperature data, etc. caused by vibration), and then transmits these relevant detection parameters to the control processor 110, so that the control processor 110 processes these relevant detection parameters using relevant analysis software to generate vibration detection results of the workpiece 200 (such as acceleration curves, frequency response diagrams, displacement and stress distribution analysis results, etc.).

[0063] Among them, the detection sensor 130 includes position sensor, acceleration sensor, stress sensor, voltage and current sensor, amplitude sensor, temperature sensor, etc.

[0064] This embodiment of the application utilizes the feature that the coil parameters of the electromagnetic coil 122 can be finely adjusted to obtain corresponding control parameters for the detection parameter types and ranges corresponding to different types of workpieces 200. This allows the magnetic drive vibration detection system 100 to meet the high-precision vibration detection requirements of different types of workpieces 200, thereby improving the reliability and versatility of the magnetic drive vibration detection system 100. Furthermore, it utilizes multiple detection sensors 130 to obtain comprehensive relevant detection parameters when the workpiece 200 is subjected to vibration detection, thereby improving the accuracy of vibration detection.

[0065] The detection parameter types for different workpiece types include acceleration, frequency response, displacement, amplitude, resonant frequency, stress, temperature, and long-term testing. For example, when the workpiece being tested is a power battery, the detection parameter types include acceleration, stress, and temperature. The specific detection methods and targets for these parameter types are shown below.

[0066] 1. Acceleration: The testing method generally involves gradually adjusting the current intensity of the electromagnetic coil 122 of the magnetic drive vibration assembly 120, thereby changing the intensity of the working magnetic field at the detection station to induce vibrations of varying intensities in the workpiece 200, resulting in different degrees of acceleration. An accelerometer is then used to measure the acceleration response and position data of the workpiece 200 under different current intensities, and this data is recorded as relevant detection parameters. The goal is to measure the performance of the workpiece 200 under different accelerations and evaluate its tolerance.

[0067] 2. Frequency Response: The test method generally involves keeping the current intensity constant and gradually adjusting the frequency of the electromagnetic coil 122 of the magnetic drive vibration assembly 120 to detect the frequency of the working magnetic field at the workstation. Accelerometers and amplitude sensors are used to record the acceleration response data and position data of the workpiece 200 at different frequencies, which are then used as recorded data for relevant detection parameters. The goal is to determine the frequency response characteristics of the workpiece 200 and identify the resonant frequency.

[0068] 3. Displacement: The test method involves setting up a fixed stator (which can be the vibration detection component 120) below the testing station, and installing a feedback scale on the fixed stator. The feedback scale can directly measure the relative displacement data of the workpiece 200 relative to the fixed stator during vibration testing, and record this data as relevant testing parameters. The goal is to ensure that the displacement of the workpiece 200 during vibration does not exceed the design range.

[0069] 4. Amplitude: The test method involves adjusting the current intensity of the electromagnetic coil 122 of the magnetic drive vibration assembly 120 to change the intensity of the working magnetic field at the detection station, causing the workpiece 200 to vibrate at different intensities. An amplitude detection sensor is then used to measure the amplitude response data of the workpiece 200, which is recorded as relevant detection parameter data. The goal is to evaluate the performance stability of the workpiece 200 under different amplitude conditions.

[0070] 5. Resonant Frequency: The test method involves gradually adjusting the frequency of the electromagnetic coil 122 of the magnetic drive vibration assembly 120, and using an amplitude detection sensor to monitor the vibration intensity of the workpiece 200 at each frequency in real time. The frequency point of maximum vibration, i.e., the resonant frequency of the workpiece 200, is then recorded as relevant test parameter data. The goal is to determine the resonant frequency of the workpiece 200 to avoid frequencies approaching this value in actual use.

[0071] 6. Stress: The test method involves applying vibrations of varying intensities to the workpiece 200 and measuring the stress distribution data within the workpiece 200 using a stress detection sensor, particularly in stress concentration areas under high vibration intensity conditions. This stress distribution data is then recorded as relevant test parameters. The objective is to detect the structural stress of the workpiece 200 under vibration and to evaluate its structural strength and reliability.

[0072] 7. Environmental Conditions: The test method involves conducting vibration tests under different environmental conditions (such as temperature and humidity) around the control and testing station, and observing the vibration response of the workpiece 200 under different environmental conditions. The goal is to simulate the vibration behavior of the workpiece 200 under real working conditions and ensure the performance reliability of the workpiece 200 under different environments.

[0073] 8. Long-term testing: The testing method involves controlling the workpiece 200 at the testing station to continuously conduct vibration tests under certain vibration intensity conditions, and observing the performance changes of the workpiece 200 after long-term vibration. The objective is to evaluate the long-term vibration tolerance of the workpiece 200.

[0074] Understandably, for different types of workpieces, there are corresponding types of detection parameters and ranges for each type. The detection parameter range refers to the range of parameters such as vibration intensity and frequency generated by the workpiece 200 itself, such as the vibration force of the workpiece 200 being 1 Newton (N) to 10 Newtons (N) and the vibration acceleration being 0.1 m / s². 2 )etc.

[0075] Then, when performing vibration detection on the workpiece 200, the control processor 110 first determines the workpiece type of the workpiece 200, and then further obtains multiple detection parameter types corresponding to the workpiece type and the detection parameter range of each detection parameter type pair. Next, the control processor 110 generates multiple discrete control parameters corresponding to the detection parameter range based on the workpiece mass M of the workpiece 200 at the detection station and the magnetic field induction area V of the workpiece 200 at the detection station that is used to generate magnetic force with the working magnetic field. These discrete control parameters can uniformly generate multiple working magnetic fields acting on the workpiece 200, and these working magnetic fields can achieve multiple discrete values ​​acting on the workpiece 200 within the detection parameter range.

[0076] Among them, the coil parameters of electromagnetic coil 122 are its own fixed parameters, such as inductance, resistance, coil permeability, number of coil turns and coil length, etc.

[0077] Reference Figure 4 This is a schematic diagram of a magnetic drive vibration detection system equipped with a detection platform, provided in an embodiment of this application. Figure 4 As shown, in the magnetic drive vibration detection system 100, a detection platform 140 carrying an induction magnet 141 is also provided at the detection station. This detection platform 140 is used to support the workpiece 200 without a magnet assembly. When the magnetic drive vibration assembly 120 generates a working magnetic field at the detection station, the induction magnet 141 in the detection platform 140 interacts with the working magnetic field to maintain the suspension and vibration of the detection platform 140 and the workpiece 200 on it, thereby improving the detection reliability of the magnetic drive vibration detection system 100. The magnetic field induction area is the orthographic projection of the induction magnet 141 of the detection platform 140 onto the plane perpendicular to the magnetic field lines of the working magnetic field, and the workpiece mass M includes the mass of the detection platform 140 and the workpiece 200. It can be understood that when the magnetic drive vibration detection system 100 is installed in a magnetic drive conveyor line, the detection platform 140 can also be a moving part transporting the workpiece 200.

[0078] Reference Figure 5 This is a schematic diagram of a workpiece equipped with a magnet assembly in a magnetic drive vibration detection system, as provided in an embodiment of this application. Figure 5As shown, certain types of workpieces 200 are also equipped with magnet assemblies 210. In this case, the magnetic field induction area is the orthographic projection of the magnet assembly 210 onto the plane of the magnetic field lines perpendicular to the working magnetic field. When the magnetic drive vibration assembly 120 generates the working magnetic field at the detection station, the magnet assembly 210 of the workpiece 200 interacts with the working magnetic field, thereby maintaining the suspension and vibration of the workpiece 200 without the need for other supports (such as movers, detection platforms 140, etc.). This reduces the setup cost of the magnetic drive vibration detection system 100 while maintaining its detection reliability.

[0079] Furthermore, when the control processor 110 executes the generation of control parameters corresponding to any parameter in the detection parameter range based on the workpiece mass M, the magnetic field induction area V, and the coil parameters of the electromagnetic coil 122 in the magnetic drive vibration assembly 120, it can calculate the parameters using some relevant electromagnetic force formulas, as detailed in the following calculation process.

[0080] This application takes a certain vibration force parameter F in the detection parameter range as an example. Then, based on the vibration force parameter F and the Ampere force formula, i.e., vibration force parameter F = current intensity I × (coil length L × magnetic induction intensity B), and combined with the relevant formula of magnetic induction intensity B and coil parameters, i.e. magnetic induction intensity B = coil permeability μ × number of coil turns N × current intensity I / coil length L, the corresponding current intensity I is obtained, and this current intensity I is used as the control parameter corresponding to the vibration force parameter F.

[0081] Based on this, the control processor 110 can accurately determine the corresponding detection parameter type and appropriate control parameters according to the different detection workpiece types and different workpiece qualities of the detection workpiece 200 placed on the detection station, so as to realize adaptive vibration detection of the detection workpiece 200, thereby effectively improving the reliability and universality of the magnetic drive vibration detection system.

[0082] Reference Figure 6 This is a schematic diagram of a magnetic drive vibration detection system equipped with functional detection components, provided in an embodiment of this application. Figure 6As shown, the magnetic drive vibration detection system 100 also includes a functional detection component 150 for performing functional tests on the workpiece 200. This functional detection component 150 is connected to the control processor 110. When the workpiece 200 is subjected to vibration detection at the detection station, or after vibration detection, the control processor 110 sends a functional detection command to the functional detection component 150. Then, in response to the functional detection command, the functional detection component 150 performs multiple preset function tests on the workpiece 200 corresponding to its workpiece type, obtains functional detection data for the workpiece 200, and sends this data to the control processor 110. The control processor 110 then combines this functional detection data to obtain the vibration detection result of the workpiece 200, thereby detecting whether the workpiece 200 will experience functional or performance degradation due to vibration, thus improving the reliability of the magnetic drive vibration detection system 100.

[0083] In some embodiments, a closed-loop control system is also employed in the magnetic drive vibration detection system 100. The control processor 110 can dynamically adjust the coil parameters (including current intensity and frequency) of the electromagnetic coil 122 of the magnetic drive vibration assembly 120 according to the real-time data fed back by the detection sensor, so as to ensure that the vibration conditions of the workpiece being tested are consistent with the test requirements.

[0084] In addition, to further improve the safety of the magnetic drive vibration detection system 100 in performing vibration detection on the workpiece 200, an adaptive clamp 160 is also provided at the detection station within the magnetic drive vibration detection system 100. When the workpiece 200 is placed at the detection station, the adaptive clamp 160 is used to hold the workpiece 200 to ensure that the workpiece 200 is firmly fixed during the test and will not undergo additional displacement due to vibration, thereby preventing the workpiece 200 from being displaced out of the detection station due to vibration.

[0085] In addition, to further improve the vibration detection accuracy of the workpiece 200 within the magnetic drive vibration detection system 100, after obtaining relevant detection parameters (including position data, acceleration response, resonant frequency, stress distribution data, etc.) and functional detection data obtained during the vibration detection of the workpiece 200, the control processor 110, based on the workpiece mass M, the magnetic drive sensing area V, and the coil parameters of the electromagnetic coil 122 of the magnetic drive vibration assembly 120, generates control parameters for the electromagnetic coil 122 corresponding to the working magnetic field that allows the workpiece 200 to float stably on the detection station. These are the static magnetic levitation control parameters. Then, the control of the current in the electromagnetic coil is adjusted. The parameters are set to the static magnetic levitation control parameters so that the workpiece 200 approaches stillness at the detection station during the vibration process. The time and amplitude of stillness change during the change from vibration to stillness of the workpiece 200 are recorded. This yields the time and amplitude required for the workpiece 200 to return to stillness when it is under external force and vibrating, which are used as the smoothing detection result of the workpiece 200. The smoothing detection result (including stillness change time and amplitude) and the static magnetic levitation control parameters are recorded as part of the vibration detection result of the workpiece 200, thereby further improving the integrity and reliability of the vibration detection of the magnetic drive vibration detection system.

[0086] The following example uses the workpiece 200 as a power battery and vibration detection in the magnetic drive vibration detection system 100.

[0087] In this scenario, the vibration environment of the power battery in actual use needs to be considered to ensure the stability and reliability of the battery module containing the power battery during production and subsequent applications. The vibration test results required for this power battery mainly include the following three points.

[0088] 1. Verify the mechanical integrity of the power battery: Ensure that the power battery will not suffer mechanical damage under normal vibration conditions, such as loose connections or damaged casing.

[0089] 2. Evaluate the electrical performance stability of the power battery: Ensure that the electrical connection of the power battery is stable and its electrical performance is not affected under normal vibration conditions.

[0090] 3. Simulate real-world application scenarios: such as vibration environments under different operating conditions during vehicle operation, including high-speed driving, bumpy roads, rapid acceleration / deceleration, etc., to detect vibration of the power battery.

[0091] Based on this, taking continuous vibration during high-speed driving, impact vibration on bumpy road sections, and vibration under different ambient temperatures as examples, the vibration test process for power batteries is designed as follows.

[0092] 1. Select a power battery as the test sample corresponding to workpiece 200. Ensure the test sample meets production standards and has no obvious defects. Adjust the test environment conditions such as temperature and humidity to the specified values ​​to simulate the actual use environment. Typically, tests are conducted in alternating ambient and high / low temperature environments. Specifically, the test environment temperature is generally set to -20℃, 25℃, and 60℃.

[0093] 2. An acceleration sensor, a stress sensor, a voltage and current sensor, and a temperature sensor are installed in the magnetic drive vibration detection system 100 to detect the impact of vibration on the power battery.

[0094] 3. Perform vibration tests at low, medium, and high frequencies in sequence, and conduct a complete test procedure under each temperature condition. The specific parameters are shown below.

[0095] 3.1) Low-frequency test: 10Hz to 50Hz, amplitude 0.5mm, test time 2 hours. Gradually increase the frequency and monitor the response of the power battery. Observe carefully for resonance phenomena or obvious mechanical / electrical abnormalities.

[0096] 3.2) Intermediate frequency test: 50Hz to 500Hz, amplitude 1mm, test time 4 hours. Pay special attention to the mechanical and internal electrical connections of the power battery.

[0097] 3.3) High-frequency test: 500Hz to 2000Hz, amplitude 0.2mm, test time 1 hour. Check for mechanical fatigue or loose or disconnected electrical connections inside the power battery.

[0098] 4. Record the changes in acceleration, stress, and temperature of the power battery during vibration testing, and analyze the impact of vibration on the mechanical structure and electrical connections of the power battery.

[0099] Specifically, for acceleration data, the acceleration response of the power battery at various frequencies is recorded. Typically, acceleration data in three axes needs to be collected to analyze the overall vibration response of the power battery. For stress data, data is collected through stress sensors to analyze the stress distribution of the internal structure of the power battery, especially key parts such as welds and connectors. For electrical performance data, electrical parameters such as voltage, current, and internal resistance of the power battery are detected during the test to check for fluctuations or abnormalities in electrical performance.

[0100] 5. Inspect the mechanical integrity and electrical performance of the power battery, and conduct discharge / charge tests to ensure the battery module functions normally after vibration. Specifically, this inspection includes: Mechanical structure inspection: After vibration testing, check the appearance of the power battery, connectors, solder joints, etc., for looseness, cracks, or other damage. Electrical performance evaluation: Measure and record the electrical performance of the power battery after vibration testing, check whether it is consistent with that before the test, and assess whether there is any performance degradation caused by vibration. Functional testing: Conduct functional tests such as discharge and charge to ensure that the power battery functions normally after vibration testing.

[0101] The following example illustrates the types of test parameters and their corresponding ranges that need to be considered when simulating high-speed driving and bumpy road sections inside an electric vehicle during vibration testing of power batteries.

[0102] The detection parameter range for acceleration is 3g to 10g. When electric vehicles are traveling at high speeds or over bumpy roads, the battery module may experience significant acceleration impacts. A higher acceleration range (e.g., 10g) is selected to simulate extreme conditions, ensuring the module's stability under high stress.

[0103] The detection parameter range corresponding to the frequency is 10Hz to 2000Hz. This covers a wide frequency range from low to high frequencies. Low frequencies are used to simulate low-frequency vibrations caused by uneven road surfaces, while high frequencies are used to simulate high-frequency vibrations during high-speed driving. Frequency scanning identifies the resonant frequency of the battery module, preventing resonance damage in practical applications.

[0104] The amplitude range for the detection parameters is 0.2mm to 3mm. The amplitude value depends on the actual road conditions being simulated. Smaller amplitudes (e.g., 0.2mm) can simulate vibrations under normal road conditions, while larger amplitudes (e.g., 3mm) can be used to simulate severe bumps and impact vibrations to evaluate the impact resistance of the battery module.

[0105] The detection parameter range for long-term testing is 1 to 8 hours for each frequency / amplitude combination. Electric vehicles typically require long-term operation, thus necessitating extended vibration testing to evaluate the long-term reliability of the battery module. Short-term testing (1 hour) is used for initial assessment, while long-term testing (8 hours) simulates the long-term vibration effects under actual operating conditions.

[0106] The temperature range for the testing parameters is -20℃ to 60℃. Electric vehicles operate under different climatic conditions, therefore vibration testing is required at different temperatures. Low temperature (-20℃) and high temperature (60℃) tests can simulate vibration behavior under extremely cold and hot environments, respectively, ensuring the stability of the battery module under extreme temperatures.

[0107] This application embodiment also provides a magnetic drive vibration detection method, which is applied to the control processor 110 in the magnetic drive vibration detection system 100 described above. (Refer to...) Figure 7 As shown, the method includes steps 701 to 702.

[0108] Step 701: Generate multiple different control parameters, and adjust the current of the electromagnetic coil according to the control parameters to generate multiple corresponding working magnetic fields at the detection station.

[0109] Step 702: Obtain the position data of the workpiece in the working magnetic field, and generate the vibration detection results of the workpiece based on the position data.
