Description

Technical Field

[0001] This invention relates to the field of vibration testing technology, and in particular to a system, method, and electronic device for testing the impact vibration response of moving parts. Background Technology

[0002] Moving parts are ubiquitous in mechanical equipment. Taking a robotic arm as a general example, when a robotic arm changes from a moving state to a stationary state, it is inevitably subjected to the impact of stopping acceleration, resulting in vibration at the stationary position. This vibration has adverse effects on the items transported by the robotic arm, the sensors installed on the robotic arm, and the strength of the robotic arm itself. Similar impact vibration phenomena are widely observed in situations such as sudden stops and turns of moving parts (where the original velocity in the direction of movement is 0).

[0003] Commonly used vibration testing equipment can be divided into two main categories: contact and non-contact. Contact testing equipment mainly uses accelerometers, which need to be installed on the object being tested. Non-contact testing equipment includes methods such as laser vibration measurement.

[0004] Using an accelerometer adds extra mass to the moving parts, affecting the accuracy of the measurement results and making it unsuitable for smaller objects. Furthermore, since the accelerometer moves with the measured part, the collected acceleration signal contains a mixture of rigid body acceleration and vibration acceleration in the low-frequency range, making it impossible to separately acquire vibration acceleration. While using a laser vibrometer avoids the drawbacks of adding mass to the accelerometer, the location of the impact vibration of the moving part and the focusing of the measured point are both manually performed, which is difficult to implement and leads to inaccurate measurement results.

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0041] Figure 1 This is a schematic diagram of the structure of the impact vibration response testing system for moving parts provided by the present invention, as shown below. Figure 1 As shown, the moving part impact vibration response testing system includes a displacement sensor 101, a moving part 102, a laser vibration meter 103, a data acquisition module 104, and a control module 105; wherein,

[0042] The displacement sensor 101 is disposed at one end of the moving component 102, and the displacement sensor 101 is connected to the data acquisition module 104 for collecting the motion displacement of the moving component 102.

[0043] The laser vibration meter 103 is connected to the data acquisition module 104 and is used to collect the impact vibration response signal of at least one test point on the moving part 102 when the moving part 102 moves to the target position.

[0044] The data acquisition module 104 is used to acquire the motion displacement and the impact vibration response signal, and send the motion displacement and the impact vibration response signal to the control module 105;

[0045] The control module 105 is connected to the data acquisition module 104 and the laser vibration meter 103 respectively. It is used to compare the motion displacement with the target displacement corresponding to the target position. When the moving part 102 moves to the target position, it controls the laser vibration meter 102 to collect the impact vibration response signal of each of the test points and process the impact vibration response signal to obtain the impact vibration response of each of the test points.

[0046] Specifically, the target position is the termination position of the movement of the moving part 102. When the moving part 102 moves from the initial position to the target position, it stops moving, that is, it changes from a moving state to a stopped state. At this time, due to the impact of the stopping acceleration, the moving part 102 generates impact vibration at the target position. The test point is at least one pre-set position on the moving part 102 that needs to be tested. It is mostly located at the unconstrained end of the moving part 102. The test point is generally the part with the most intense vibration, that is, the unconstrained end of the moving part 102. The number of test points can be set according to the actual situation, and there is no limit to the comparison. The impact vibration response signal is the time-domain vibration signal measured at the test point when the moving part 102 moves to the target position.

[0047] Optionally, the moving part 102 can be a precision moving part such as an integrated circuit wafer transfer robot.

[0048] In practice, the displacement sensor 101 is positioned at one end of the moving component 102, near the root of the fixed component 106, to avoid the displacement sensor 101 affecting the vibration of the unconstrained end of the moving component 102. The displacement sensor 101 is connected to the data acquisition module 104 via a data cable, and its displacement is collected in real time as the moving component 102 moves along the direction of motion. The laser vibration meter 103 is connected to the data acquisition module 104 via a data cable and is used to collect the impact vibration response signal of at least one test point on the moving component 102 when the moving component 102 moves to the target position.

[0049] Since the data acquisition module 104 is connected to the displacement sensor 101 and the laser vibration meter 103 respectively, the data acquisition module 104 is used to acquire the motion displacement collected by the displacement sensor 101 and the impact vibration response signal collected by the laser vibration meter 103, and send the motion displacement and impact vibration response signal to the control module 105. The control module 105 is connected to the data acquisition module 104 and the laser vibration meter 103 respectively. After acquiring the motion displacement collected by the displacement sensor 101, it compares the motion displacement with the target displacement corresponding to the target position. When the moving part 102 moves to the target position, the control module 105 triggers the laser emitter of the laser vibration meter 102, and controls the laser vibration meter 102 to collect the impact vibration response signal of each test point. After the laser vibration meter 102 collects the impact vibration response signal, it sends it to the control module 105 through the data acquisition module 104. The control module 105 processes the impact vibration response signal to obtain the impact vibration response of each test point.

[0050] Optionally, the laser vibrometer 103 is positioned on the same straight line as the moving part 102 and aligned with the point to be measured.

[0051] Specifically, the laser vibration meter 103 is a single-point laser vibration meter. The laser vibration meter 103 is set on the outside of the moving part 102 and in the area where the moving part 102 is not vibrating, through a laser vibration meter bracket. The position of the laser vibration meter 103 is on the same straight line as the moving part 102, that is, the laser vibration meter 103 can be set below the moving part 102 or above the moving part 102. The specific position of the laser vibration meter 103 depends on the movement direction of the moving part 102. The laser vibration meter 103 is aligned with the point to be measured, and the laser is focused on the point to be measured on the moving part 102 when the movement of the moving part 102 ends.

[0052] The present invention provides a moving part impact vibration response testing system, comprising: a displacement sensor, a moving part, a laser vibrometer, a data acquisition module, and a control module; wherein, the displacement sensor is disposed at one end of the moving part and connected to the data acquisition module for acquiring the displacement of the moving part; the laser vibrometer is connected to the data acquisition module for acquiring the impact vibration response signal of at least one test point on the moving part when the moving part moves to a target position; the data acquisition module is used to acquire the displacement and impact vibration response signal and send them to the control module; the control module is connected to both the data acquisition module and the laser vibrometer, and is used to compare the displacement with the target displacement corresponding to the target position, and when the moving part moves to the target position, control the laser vibrometer to acquire the impact vibration response signal of each test point, process the impact vibration response signal to obtain the impact vibration response of each test point, thereby realizing the testing of the impact vibration response of the moving part and improving the testing accuracy of the impact vibration response.

[0053] Optionally, the moving component 102 includes at least one of the following: a wire displacement sensor; a magnetostrictive displacement sensor; or a laser displacement sensor.

[0054] Optionally, the impact vibration response includes at least one of the following: vibration displacement; vibration acceleration; vibration velocity; vibration frequency; and impact decay time.

[0055] Figure 2 This is one of the flowcharts illustrating the impact vibration response testing method for moving parts provided by the present invention, such as... Figure 2 As shown, this method is applied to a moving part impact vibration response testing system, including steps 201-204; wherein,

[0056] Step 201: Obtain the motion displacement of the moving parts.

[0057] It should be noted that before acquiring the displacement of the moving part, a displacement sensor is installed. The moving part is then guided to complete its motion from the initial position to the target position (the final position) and stop at the target position. The displacement sensor obtains the final displacement of the moving part when it stops at the target position and inputs this final displacement to the control module through the data acquisition module. The laser sensor in the laser vibrometer is then aligned with at least one test point on the moving part when it is at the target position. The surface of the test point is cleaned, and for test points with poor surface quality, a cloth is applied. Next, the laser generator in the laser vibrometer is activated and focused on the test point at the target position. The moving part is then reset, that is, returned to its initial position, and the displacement sensor is zeroed. The moving part is then activated, and the motion test begins. During the test, the displacement sensor acquires the displacement of the moving part in real time, thus enabling real-time acquisition of the moving part's displacement.

[0058] Step 202: Based on the motion displacement, determine whether the moving component has moved to the target position.

[0059] Specifically, based on the displacement of the moving parts, it can be further determined whether the moving parts have moved to the target position.

[0060] Step 203: When the moving part moves to the target position, control the laser vibration meter to collect the impact vibration response signal of at least one test point on the moving part.

[0061] Specifically, the impact vibration response signal is the time-domain vibration signal measured at the test point when the moving part moves to the target position. When the moving part moves to the target position, the moving part is impacted, and at least one test point on the moving part is also impacted. The impact vibration response signals of one or more test points on the moving part can be collected by controlling a laser vibrometer.

[0062] Step 204: Based on the impact vibration response signal, determine the impact vibration response of each of the test points.

[0063] Specifically, the impact vibration response includes at least one of the following: vibration displacement; vibration acceleration; vibration velocity; vibration frequency; and impact decay time. Based on the impact vibration response signal, the impact vibration response at each test point can be determined.

[0064] The present invention provides a method for testing the impact vibration response of moving parts. By acquiring the displacement of the moving part, it determines whether the moving part has moved to the target position. When the moving part moves to the target position, it controls a laser vibrometer to collect the impact vibration response signal of at least one test point on the moving part. Based on the impact vibration response signal, it determines the impact vibration response of each test point, thereby realizing the testing of the impact vibration response of the moving part and improving the testing accuracy of the impact vibration response.

[0065] Optionally, the specific implementation process of step 202 above includes:

[0066] The motion displacement is compared with the target displacement corresponding to the target position; if the motion displacement is the same as the target displacement, it is determined that the moving component has moved to the target position; or, if the motion displacement is not the same as the target displacement, it is determined that the moving component has not moved to the target position.

[0067] Specifically, the target displacement is the displacement of the moving part from its initial position to its target position. The moving displacement is compared with the target displacement corresponding to the target position. If the moving displacement and the target displacement are the same, it can be determined that the moving part has reached the target position, i.e., the real-time moving displacement has reached the termination displacement; or, if the moving displacement and the target displacement are different, it can be determined that the moving part has not reached the target position, i.e., the real-time moving displacement has not reached the termination displacement. The target displacement determination triggers the laser vibrometer, ensuring that all impact vibration response signals collected by the laser vibrometer are valid data. Data processing is simple and efficient.

[0068] The present invention provides a method for testing the impact vibration response of moving parts. By comparing the moving displacement of the moving part with the target displacement corresponding to the target position, the method determines that the moving part has moved to the target position when the moving displacement is the same as the target displacement, or that the moving part has not moved to the target position when the moving displacement is different from the target displacement. This method enables the determination of whether the moving part has moved to the target position. Furthermore, it allows the control of a laser vibrometer to collect the impact vibration response signal of at least one test point on the moving part, determine the impact vibration response of each test point, and test the impact vibration response of the moving part. This improves the testing accuracy of the impact vibration response and allows for further evaluation of the intensity level of the impact vibration response, guiding subsequent optimization and debugging.

[0069] Optionally, the specific implementation of step 204 above includes:

[0070] The impact vibration response signal is processed to determine the impact vibration response of each of the test points.

[0071] Specifically, the impact vibration response signal is processed, which involves processing the time-domain vibration signal measured at the test point when the moving part reaches the target position. Further, the time-domain vibration signal is the time-domain velocity signal acquired by the laser probe. The processing includes: 1. Filtering; 2. Integrating the time-domain velocity signal to obtain the vibration displacement, and differentiating the time-domain velocity signal to obtain the vibration acceleration; 3. Extracting the peak values ​​of the vibration velocity, vibration displacement, and vibration acceleration corresponding to the time-domain velocity signal at each moment, thereby determining the impact vibration response of each test point. Furthermore, the vibration frequency and impact vibration decay time can also be determined based on the time-domain velocity signal.

[0072] The present invention provides a method for testing the impact vibration response of moving parts. By processing the impact vibration response signal, the impact vibration response of each test point is determined. The processing of the impact vibration response signal does not require complex data processing procedures such as data truncation, which reduces the influence of noise and improves the testing accuracy of impact vibration response.

[0073] Figure 3 This is the second flowchart of the impact vibration response testing method for moving parts provided by the present invention, as shown below. Figure 3 As shown, the method includes steps 301-306; wherein,

[0074] Step 301, motion assessment. Before acquiring the motion displacement of the moving part, a displacement sensor is installed. The moving part is made to complete a full motion from the initial position to the target position (motion termination position) and stop at the target position. The displacement sensor obtains the termination displacement of the moving part when it stops at the target position and inputs the termination displacement to the control module through the data acquisition module.

[0075] Step 302, Laser Vibration Meter Setup and Focusing. Place the laser vibration meter below the moving part, i.e., in an external, vibration-free area. Align the laser sensor in the laser vibration meter with at least one test point on the moving part when it is in the target position. Clean the surface of the test point; for test points with poor surface quality, apply a protective layer. Activate the laser generator in the laser vibration meter and focus it on the test point at the target position.

[0076] Step 303, Motion Test. Reset the moving part, that is, restore the moving part to its initial position and zero the displacement sensor. Start the moving part and begin the motion test. During the test, the displacement sensor collects the motion displacement of the moving part in real time, thereby obtaining the motion displacement of the moving part in real time.

[0077] Step 304: Compare the motion displacement with the target displacement corresponding to the target position to determine whether the motion displacement and the target displacement are the same; if the motion displacement and the target displacement are the same, proceed to step 305; if the motion displacement and the target displacement are not the same, proceed to step 303.

[0078] Step 305: Trigger and control the laser vibration meter to collect the impact vibration response signal of at least one test point on the moving part.

[0079] Step 306: Process the impact vibration response signal to determine the impact vibration response of each test point.

[0080] The impact vibration response testing method for moving parts provided by this invention can quickly obtain the impact vibration response of moving parts using a simple moving part (testing device), including vibration displacement, vibration acceleration, vibration frequency, and impact vibration decay time. The impact vibration response testing system for moving parts provided by this invention triggers a laser vibrometer by determining the motion displacement of the moving part, ensuring that all collected vibration data (impact vibration response signals) are valid data. Data processing is simple and efficient. On the one hand, the vibration data does not include rigid body motion, eliminating the need for complex data processing such as data truncation; on the other hand, it reduces the influence of noise and improves measurement accuracy.
