[0002] With technological advancements, there is a growing need to test the dust-attracting performance of various devices, such as AR glasses glass. However, current methods for measuring the dust-attracting performance of AR glasses glass involve numerous and time-consuming steps, some of which are difficult to execute and prone to significant errors, resulting in low accuracy. Furthermore, the limited testing environment leads to inconsistent data. For instance, measuring the contact angle of the glass surface involves placing the AR glasses glass outdoors for extended periods to observe dust accumulation. This testing method has a long testing cycle, and the highly unstable outdoor testing environment (e.g., varying weather conditions each time the glass is placed outdoors) further contributes to inaccurate results. Therefore, improving the accuracy of dust-attracting performance testing has become an urgent problem to solve.
[0003] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0020] The sample to be tested is placed in a preset natural environment, and after a second preset time, the sample to be tested is retrieved from the natural environment. The degree of adhesion and distribution of the test substance on the surface of the sample to be tested retrieved from the natural environment are then detected.
[0021] In one embodiment, the third detection result includes the first measurement result and the second measurement result. The step of measuring the contact angle of the water droplet on the surface of the sample to be tested to obtain the third detection result includes:
[0022] The sample to be tested recovered based on the artificial pollution test is used as the first sample to be tested, and the sample to be tested recovered based on the natural exposure test is used as the second sample to be tested.
[0023] The contact angle of the water droplet on the surface of the first sample to be tested is measured to obtain a first measurement result, and the contact angle of the water droplet on the surface of the second sample to be tested is measured to obtain a second measurement result.

[0033] In this application, by determining the selected sample and analyte to be tested, and the type of test to be performed, the dust-adhesion performance of the sample to be tested can be evaluated according to different test types. Since the test types include artificial contamination testing, natural exposure parameters, and water droplet roll-off angle measurement, the following methods are used: In artificial contamination testing, the adhesion and distribution of the analyte on the surface of the sample to be tested are measured in a preset testing environment to obtain a first test result; in natural exposure testing, the adhesion and distribution of the analyte on the surface of the sample to be tested are measured in a natural environment to obtain a second test result; and in water droplet roll-off angle measurement, the contact angle of the water droplet on the surface of the sample to be tested is measured to obtain a third test result. The dust-adhesion performance test result of the sample to be tested is determined based on at least one of the first, second, and third test results. Furthermore, the adhesion and influence of each analyte on the surface of the sample to be tested can be evaluated using the first test result. And when the sample to be tested is AR glasses, the adhesion and influence of the analyte on the glass surface of the AR glasses can be evaluated.

Furthermore, the third test result can determine the hydrophilicity or hydrophobicity of the sample, thereby indirectly assessing its dust-collecting performance. Moreover, by combining the first, second, and third test results, the dust-collecting performance of the sample can be comprehensively determined, thereby improving the accuracy of dust-collecting performance testing.

[0041] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0042] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.
[0043] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.
[0044] Based on this, the embodiments of this application provide a method for detecting dust-collecting performance, referring to... Figure 1 , Figure 1 This is a flowchart illustrating the first embodiment of the dust-collecting performance testing method of this application.
[0045] In this embodiment, the dust-adhesion performance testing method includes steps S10 to S50.
[0046] Step S10: Determine the selected sample to be tested and the analyte, and determine the type of test to be performed on the sample to be tested;
[0047] The types of tests include artificial contamination testing, natural exposure testing, and water droplet roll angle measurement.
[0048] It should be noted that the sample to be tested can be a product that requires dust adhesion performance testing, such as the glass surface of AR glasses, or the glass surface of other devices with glass components. Optionally, the test substance can be a contaminant.
[0049] Optionally, multiple samples of the same type can be selected for testing, such as AR glasses, to ensure that each sample is consistent in size, material, and other aspects.
[0050] Optionally, the pollutant to be tested for dust collection performance can be selected from multiple pollutants of different types as the test object.
[0051] In one feasible embodiment, the detected substance includes at least one of dust, grease, and simulated traffic pollutants.
[0052] Optionally, the detected substance may include fine particulate matter, such as dust. It may include grease, such as oil stains left by simulated finger touch. It may include simulated traffic pollutants, such as particulate matter in simulated vehicle exhaust.
[0053] Optionally, the type of test to be performed on the sample needs to be determined. For example, artificial contamination testing can be conducted under simulated contamination conditions in a laboratory setting. Natural exposure testing, on the other hand, can be performed in a real natural environment to test the sample's performance in actual use. Water droplet roll-off angle measurement can assess the cleanliness of the sample's surface using a contact angle measuring instrument, such as the cleanliness of the glass surface of AR glasses.
[0054] Optionally, when testing the dust-collecting performance of the sample, a terminal device, such as a robot, can be used to select the sample and analyte according to user-inputted instructions, and the test type can be determined based on the test type selected by the user on the terminal device's display interface. Manual operation is also possible, and there are no restrictions on this method.
[0055] Step S20: If the detection type is artificial contamination test, the adhesion and distribution of the test substance on the surface of the sample to be tested are detected in a preset detection environment to obtain the first detection result.
[0056] Optionally, if artificial contamination testing is required, a preset testing environment, such as a laboratory environment, can be constructed in advance. Furthermore, the environmental parameters of the preset testing environment can be adjusted to simulate different real-world scenarios.
[0057] Optionally, when the test type is determined to be artificial contamination test, the sample to be tested can be tested in a preset test environment, such as placing the AR glasses in a laboratory environment and testing the AR glasses in the laboratory environment.
[0058] Optionally, when testing the sample, the analyte adhering to the sample surface can be detected in a preset testing environment after a certain period of time to determine the degree of adhesion and distribution of the analyte on the sample surface. Furthermore, the degree of adhesion and distribution of the analyte on the sample surface can be detected using a microscope or optical microscope to obtain the first test result.
[0059] For example, the adhesion and distribution of dust, grease, and / or simulated traffic pollutants on the surface of AR glasses can be detected using a microscope or optical microscope to obtain the first detection result, such as the density of dust on the surface of AR glasses.
[0060] Step S30: If the detection type is natural exposure test, the adhesion and distribution of the test substance on the surface of the sample to be tested are detected in a preset natural environment to obtain the second detection result.
[0061] Alternatively, if the test type is determined to be a natural exposure test, the natural environment, such as a suburban area or a seaside environment, can be determined in advance. The sample to be tested can be exposed to the natural environment, for example, by placing the AR glasses on a table by the sea.
[0062] Optionally, the sample to be tested can be placed in a natural environment for a certain period of time, and the adhesion and distribution of the analyte on the surface of the sample can be detected to obtain a second test result. Furthermore, during the test, the adhesion and distribution of the analyte on the surface of the sample can be detected using a microscope or an optical microscope.
[0063] Optionally, when conducting artificial contamination testing and natural exposure testing, two identical samples can be selected, one for artificial contamination testing and the other for natural exposure testing.
[0064] Step S40: If the detection type is water droplet rolling angle measurement, then measure the contact angle of the water droplet on the surface of the sample to be tested to obtain the third detection result.
[0065] Optionally, the contact angle can be the angle formed by the surface tension of the liquid at the point of contact between the liquid and the solid surface when a liquid (such as a water droplet) falls onto a solid surface (such as the surface of the sample to be tested, or the glass surface of AR glasses). In other words, it is the angle between the line tangent to the sample surface at the edge of the water droplet and the line perpendicular to the sample surface.
[0066] Optionally, the contact angle may include a static contact angle, a forward contact angle, and a backward contact angle. When a water droplet is stationary on the surface of the sample to be tested, the contact angle is the static contact angle. If the water droplet moves on the surface of the sample to be tested, the contact angle will change, resulting in a forward contact angle and a backward contact angle. The forward contact angle can be the maximum contact angle when the water droplet moves forward, and the backward contact angle can be the minimum contact angle when the water droplet moves backward.
[0067] Optionally, when the detection type is determined to be water droplet rolling angle measurement, the sample to be tested can be determined, and the contact angle of the water droplet on the surface of the sample can be measured using a contact angle measuring instrument (such as a contact angle meter or a dynamic contact angle measuring system) to obtain a third detection result.
[0068] Optionally, the contact angle can reflect the hydrophilicity and hydrophobicity of the sample surface. A smaller contact angle, such as less than 90 degrees, indicates a hydrophilic surface. A larger contact angle, such as greater than 90 degrees, indicates a hydrophobic surface. Furthermore, since the analyte can alter the hydrophilicity and hydrophobicity of the sample surface, it affects the contact angle of water droplets. Therefore, a larger contact angle in the third detection result indicates a cleaner sample surface.
[0069] Step S50: Determine the dust-collecting performance test result of the sample to be tested based on at least one of the first test result, the second test result, and the third test result.
[0070] Optionally, if at least one of the following is determined: a first test result from artificial contamination testing, a second test result from natural exposure testing, and a third test result from water droplet roll-off angle measurement, then at least one of these three results determines the dust-collecting performance test result. For example, based on the first test result, the degree of adhesion and distribution of the analyte on the surface of the sample under simulated testing environments can be determined, and then the dust-collecting performance test result can be determined based on this degree of adhesion and distribution. Alternatively, based on the second test result, the degree of adhesion and distribution of the analyte on the surface of the sample under actual natural environments can be determined, and then the dust-collecting performance test result can be determined based on this degree of adhesion and distribution. Or, based on the third test result, the dust-collecting performance test result can be indirectly determined by measuring the contact angle. The first, second, and third test results can also be summarized and analyzed to determine the dust-collecting performance test result of the sample.
[0071] In addition, to aid in understanding the test procedure for dust-collecting performance testing in this embodiment, an example is provided below.
[0072] For example, such as Figure 2 As shown, a sample can be selected as the test sample, and the analyte can be selected. Testing can be conducted under different conditions, such as artificial contamination testing, natural exposure testing, and water droplet roll-off angle measurement. Test data can be collected and recorded based on the artificial contamination test, natural exposure test, and / or water droplet roll-off angle measurement. Then, the test data can be analyzed to obtain the dust-adhesion performance test results for the test sample.
[0073] In this embodiment, by determining the selected sample and analyte, and the type of test to be performed, the dust-adhesion performance of the sample can be tested according to different test types. Since the test types include artificial contamination testing, natural exposure parameters, and water droplet roll-off angle measurement, the following steps are taken: In the artificial contamination test, the adhesion and distribution of the analyte on the sample surface are measured in a preset testing environment to obtain a first test result; in the natural exposure test, the adhesion and distribution of the analyte on the sample surface are measured in a natural environment to obtain a second test result; and in the water droplet roll-off angle measurement, the contact angle of the water droplet on the sample surface is measured to obtain a third test result. The dust-adhesion performance test result of the sample is determined based on at least one of the first, second, and third test results. Furthermore, the adhesion and influence of each analyte on the sample surface can be evaluated using the first test result. When the sample is AR glasses, the adhesion and influence of the analyte on the AR glasses glass surface can be evaluated. The second test result can be used to assess the adhesion and impact of the analyte on the sample after long-term exposure to the natural environment, thereby determining the degree of dust and contamination accumulation on the sample under long-term exposure, and thus comprehensively evaluating the dust-collecting performance of the sample. Furthermore, the third test result can determine the hydrophilicity or hydrophobicity of the sample, thereby indirectly assessing its dust-collecting performance. Moreover, by combining the first, second, and third test results, the dust-collecting performance of the sample can be comprehensively determined, thereby improving the accuracy of dust-collecting performance testing.
[0074] Based on the first embodiment of this application, a second embodiment of this application is proposed. In this second embodiment, content that is the same as or similar to the above embodiment can be referred to the above description and will not be repeated hereafter. Furthermore, the first detection result includes a fourth detection result.
[0075] Optionally, step S20, which involves detecting the adhesion and distribution of the analyte on the surface of the sample to be tested in a preset testing environment to obtain a first test result, includes step a10.
[0076] Step a10: Determine the detection status of the artificial contamination test. If the detection status is static contamination test, then in the preset detection environment, the analyte is evenly applied to the surface of the sample to be tested, and the environmental status of the preset detection environment is updated and adjusted. After a first preset time, the adhesion and distribution of the analyte on the surface of the sample to be tested are detected to obtain the fourth detection result.
[0077] Optionally, when conducting artificial contamination testing, the detection status for artificial contamination testing can be determined first.
[0078] Optionally, when it is determined that a static contamination test is required, a certain amount of the analyte can be determined in a preset testing environment and evenly applied to the surface of the sample to be tested. For example, in a laboratory environment, a specific type and amount of analyte (at least one of dust, grease, or simulated traffic pollutants) can be evenly applied to the surface of the AR glasses glass.
[0079] Optionally, the environmental conditions of the preset detection environment can be updated and adjusted to simulate different scenarios, and the sample to be tested can be tested under different scenarios. Optionally, after placing the sample coated with the analyte in the preset detection environment, the environmental conditions of the preset detection environment can be updated and adjusted to simulate different scenarios, such as different temperatures and humidity levels, and the degree of adhesion and distribution of the analyte on the surface of the sample. Optionally, after a first preset time (which can be any time set by the user in advance, such as 5 minutes), the degree of adhesion and distribution of the analyte on the surface of the sample can be detected using a microscope or optical microscope, and the detection result obtained in this detection is used as the fourth detection result. Multiple static contamination tests in artificial contamination tests can be performed to obtain multiple fourth detection results. All fourth detection results are summarized to obtain the first detection result.
[0080] In this embodiment, during both artificial and static contamination testing, the analyte is uniformly applied to the surface of the sample under test in a preset testing environment. The environmental conditions of the preset testing environment are updated and adjusted to simulate different scenarios. After a first preset time, the adhesion and distribution of the analyte on the sample surface are detected to obtain a fourth test result. This allows for the determination of the adhesion and influence of different types of analytes on the sample surface under different scenarios, ensuring the accuracy of the obtained fourth test result.
[0081] Optionally, in one feasible embodiment, the environmental conditions include temperature and humidity.
[0082] Optionally, step a10, which involves updating and adjusting the environmental state of the preset detection environment, includes at least one of steps a11-a12:
[0083] Step a11: Update and adjust the temperature in the preset detection environment according to the preset temperature threshold;
[0084] Step a12: Update and adjust the humidity in the preset detection environment according to the preset humidity threshold.
[0085] Optionally, the temperature threshold can be a pre-set temperature value. The humidity threshold can be a pre-set humidity value.
[0086] Optionally, after receiving a temperature adjustment command input by the user, the temperature in the predicted detection environment can be updated and adjusted based on the temperature adjustment command and temperature thresholds. For example, one or more temperature thresholds can be added to the predicted temperature. Alternatively, one or more temperature thresholds can be removed from the predicted temperature.
[0087] Optionally, after receiving a humidity adjustment command input by the user, the humidity in the predicted detection environment can be updated and adjusted based on the humidity adjustment command and humidity thresholds. For example, one or more humidity thresholds can be added to the predicted humidity in the detection environment. Or, one or more humidity thresholds can be removed from the predicted humidity in the detection environment.
[0088] Optionally, the environmental conditions may also include light intensity. The light intensity in the preset detection environment may be updated and adjusted according to a pre-set light intensity threshold, such as increasing or decreasing the light intensity.
[0089] In this embodiment, the temperature in the preset detection environment is updated and adjusted according to a preset temperature threshold, and the humidity in the preset detection environment is updated and adjusted according to a preset humidity threshold. This allows for the simulation of humid and dry environments, enabling artificial contamination testing of the sample under different conditions and ensuring the effective conduct of artificial contamination testing.
[0090] Optionally, in one feasible embodiment, the first detection result includes the fifth detection result.
[0091] Optionally, step a20 is included after step a10, which determines the detection status of the artificial contamination test.
[0092] Step a20: If the detection state is dynamic contamination test, the sample to be tested is exposed to the preset detection environment, and the test substance is periodically released into the preset detection environment. After a second preset time, the sample to be tested exposed to the preset detection environment is recovered, and the adhesion degree and distribution of the test substance on the surface of the recovered sample to be tested are detected to obtain the fifth detection result.
[0093] In this embodiment, when conducting artificial contamination testing, the detection state for artificial contamination testing can be determined first. When it is determined that dynamic contamination testing is required, a desktop can be set up in a preset detection environment, and the sample to be tested can be placed on the desktop so that the sample to be tested is exposed to the preset detection environment.
[0094] Optionally, the analyte can be periodically released into a preset testing environment using a dust generator or air pollution simulation device. Optionally, the total amount of analyte released using the dust generator or air pollution simulation device during the period is the same as the total amount of analyte applied to the surface of the sample to be tested during a static pollution test.
[0095] Optionally, the sample to be tested can be exposed to a preset detection environment containing the analyte, and after waiting for a second preset time, the sample can be retrieved. Optionally, the second preset time can be a pre-set time, which can be the same as or different from the first preset time, and there is no limitation on this.
[0096] Optionally, the recovered sample to be tested can be examined, and the adhesion and distribution of the analyte on the surface of the recovered sample can be detected using a microscope or optical microscope. The test results are then used as the fifth test result. Furthermore, multiple dynamic contamination tests can be performed in the artificial contamination test to obtain multiple fifth test results. All fifth test results are then summarized to obtain the first test result.
[0097] Optionally, during the artificial contamination testing phase, when conducting static and dynamic contamination tests, two identical samples can be selected, one for static contamination testing and the other for dynamic contamination testing.
[0098] In this embodiment, during dynamic contamination testing, the sample to be tested is exposed to a preset testing environment, and the test substance is periodically released. After a second preset time, the sample to be tested is recovered, and the adhesion and distribution of the test substance on the surface of the recovered sample to be tested are detected to obtain a fifth test result. The fifth test result can then be used to assess the dust and contamination accumulation of the sample to be tested (such as AR glasses glass) under long-term exposure, ensuring the accuracy of the obtained fifth test result.
[0099] Optionally, in a feasible embodiment, step S30, which involves detecting the adhesion and distribution of the analyte on the surface of the sample to be tested in a preset natural environment, includes step b10.
[0100] Step b10: Place the sample to be tested in a preset natural environment, and after a second preset time, retrieve the sample to be tested from the natural environment, and detect the adhesion and distribution of the test substance on the surface of the sample to be tested retrieved from the natural environment.
[0101] Optionally, when conducting natural exposure tests on the samples to be tested, the natural environment to be tested can be determined first, such as a suburban area or a seaside location. The samples to be tested can be placed in this natural environment to expose them to the natural environment, such as placing AR glasses on rocks in a suburban area.
[0102] Optionally, after a second preset time, the sample to be tested placed in the natural environment is recovered, and the recovered sample to be tested can be tested by a microscope or optical microscope to determine the degree of adhesion and distribution of the test substance on the surface of the sample to be tested, and the test result obtained is used as the second test result.
[0103] In this embodiment, the sample to be tested is placed in a natural environment, retrieved after a second preset time, and then the adhesion and distribution of the analyte on the sample surface are detected to obtain a second detection result. This achieves a simulated testing process in a real-world scenario, ensuring the accuracy of the obtained second detection result.
[0104] Optionally, in one feasible embodiment, the third detection result includes the first measurement result and the second measurement result.
[0105] Optionally, step S40, which measures the contact angle of a water droplet on the surface of the sample to be tested and obtains a third detection result, includes steps c10-c20.
[0106] Step c10: The sample to be tested recovered based on artificial pollution testing is used as the first sample to be tested, and the sample to be tested recovered based on natural exposure testing is used as the second sample to be tested.
[0107] Step c20: Measure the contact angle of the water droplet on the surface of the first sample to be tested to obtain the first measurement result; measure the contact angle of the water droplet on the surface of the second sample to be tested to obtain the second measurement result.
[0108] Optionally, artificial contamination testing and natural exposure testing can be conducted before measuring the water droplet roll-off angle. The sample recovered during the dynamic contamination test in the artificial contamination test is used as the first sample to be tested. Optionally, the sample recovered during the static contamination test in the artificial contamination test can also be used as the first sample to be tested. Optionally, the sample recovered during the natural exposure test is used as the second sample to be tested. Optionally, the first and second samples to be tested can be AR glasses of the same specifications.
[0109] Optionally, the contact angle of the water droplet on the surface of the first sample to be tested can be measured using a contact angle measuring instrument (such as a contact angle meter or a dynamic contact angle measuring system) to obtain a first measurement result. Then, the contact angle of the water droplet on the surface of the second sample to be tested can be measured using the same instrument to obtain a second measurement result. Optionally, multiple water droplet roll-off angle measurements can be performed to obtain multiple first measurement results and multiple second measurement results, which can then be aggregated to obtain a third detection result.
[0110] In this embodiment, during the water droplet roll-off angle measurement, the sample recovered from the artificial contamination test is identified as the first sample to be tested, and the sample recovered from the natural exposure test is identified as the second sample to be tested. The contact angles of the water droplets on the surfaces of the first and second samples are measured respectively, and the first and second measurement results are obtained, which are then used as the third test result. This ensures the accuracy and validity of the obtained third test result.
[0111] In addition, to aid in understanding the complete process of the dust-collecting performance test in this embodiment, an example is provided below.
[0112] For example, such as Figure 3 As shown, the AR glasses to be tested were selected as the sample, and an experimental site was chosen to determine the preset testing environment. This experimental site can simulate either a dry or humid environment. Experiments were conducted on the AR glasses to be tested in the selected experimental site, including artificial contamination testing, natural exposure testing, and water droplet roll-off angle measurement. The artificial contamination testing included both static and dynamic contamination testing.
[0113] During static contamination testing, specific types and amounts of contaminants (such as dust, grease, and simulated traffic pollutants) are uniformly applied to the display glass surface of AR glasses in a controlled laboratory environment. After a period of time, the adhesion and distribution of the contaminants are examined using a microscope or optical microscope (to assess the adhesion and impact of different types of contaminants on the display glass surface of AR glasses). The test items include the contaminants.
[0114] During dynamic pollution testing, a dust generator or air pollution simulation device is used to expose the glass surface of the AR glasses display to the screen for a specific period. After a period of time, the adhesion and distribution of pollutants are examined using a microscope or optical microscope (this method more closely approximates actual usage conditions and can assess the accumulation of dust and pollution under long-term exposure).
[0115] During natural exposure testing, AR glasses samples are placed in natural environments, such as urban areas, suburbs, or beaches, and then retrieved and examined after a period of time. The degree of contaminant adhesion and distribution are examined using a microscope or optical microscope (to assess the glass's resistance to contamination and its long-term performance in different environments).
[0116] When determining the water droplet roll-off angle, a contact angle measuring instrument, such as a contact angle measuring instrument or a dynamic contact angle measuring system, is used to measure the contact angle of the water droplet on the glass surface. The larger the contact angle, the cleaner the glass surface. Contaminants can change the hydrophilicity or hydrophobicity of the surface, thus affecting the contact angle of the water droplet.
[0117] Furthermore, embodiments of this application provide a dust-collecting performance testing device, referring to... Figure 4 The dust-collecting performance testing device includes:
[0118] The detection module A10 is used to determine the selected sample and analyte to be tested, and to determine the type of test to be performed on the sample. The test types include artificial contamination test, natural exposure test and water droplet roll angle measurement.

[0123] Optionally, the first test result includes a fourth test result, the artificial contamination test module A20, used for:
[0124] The detection state of the artificial contamination test is determined. If the detection state is static contamination test, the analyte is evenly applied to the surface of the sample to be tested in the preset detection environment. The environmental state of the preset detection environment is updated and adjusted. After the first preset time, the adhesion and distribution of the analyte on the surface of the sample to be tested are detected to obtain the fourth detection result.
[0125] Optionally, the environmental conditions include temperature and humidity. The environmental conditions of the preset detection environment are updated and adjusted, including at least one of the following:
[0126] The temperature in the preset detection environment is updated and adjusted based on the preset temperature threshold.

[0128] Optionally, the first test result includes a fifth test result, and the artificial contamination test module A20 is used for:
[0129] If the detection state is dynamic contamination test, the sample to be tested is exposed to the preset detection environment, and the test substance is periodically released into the preset detection environment. After a second preset time, the sample to be tested exposed to the preset detection environment is recovered, and the adhesion and distribution of the test substance on the surface of the recovered sample to be tested are detected to obtain the fifth detection result.
[0130] Optionally, the natural exposure test module A30 is used for:
[0131] The sample to be tested is placed in a preset natural environment, and after a second preset time, the sample to be tested is retrieved from the natural environment.

[0132] Optionally, the third detection result includes the first measurement result and the second measurement result. The water droplet roll angle measuring module A40 is used for:
