Description

Technical Field

[0001] The present invention relates to the technical field of mobile phone testing, and more specifically, to a method and system for testing the graded pressure-maintaining and waterproof properties of a mobile phone mid-plate. Background Art

[0002] In the field of mobile phone testing, the method, significance and importance of studying the graded pressure-maintaining waterproof test method for mobile phone mid-boards are reflected in simulating various underwater environmental conditions by precisely controlling the pressure-maintaining standards of different levels, thereby evaluating the waterproof performance of mobile phone mid-boards. This test method not only ensures that mobile phones maintain their functional integrity and safety in underwater environments of different depths and lengths, but also plays a vital role in enhancing consumer confidence, extending the service life of equipment, and meeting international protection standards. In this way, manufacturers can optimize product design, reduce the risk of product recalls due to waterproof failure, and provide consumers with more reliable and durable smartphone products.

[0003] Prior to the present invention, existing methods for testing the waterproofness of mobile phone mid-boards by graded pressure-holding mainly relied on manual or semi-automatic testing processes. These methods usually involve placing the mid-board of a mobile phone in a sealed test chamber, and then applying a certain amount of water pressure or air pressure through an external device to simulate the pressure environment at different depths underwater. The tester needs to closely monitor the pressure changes, manually release the pressure after reaching the predetermined pressure-holding time, and finally check whether there is water infiltration or other signs of damage to the mid-board. The technical difficulties and key points of this method include: Precise control of pressure: Ensure that the pressure applied during the entire test process is neither overloaded nor underloaded to avoid unnecessary damage to the mid-board or failure to achieve the expected test results. Accurate control of the pressure-holding time: The pressure-holding time must be accurately controlled to ensure the accuracy and repeatability of the test results. Low degree of automation: Due to reliance on manual operation, these methods have a low degree of automation, which may lead to operational errors and affect the consistency and reliability of the test results. Data recording and analysis: Manually recording test data is prone to errors, and it is difficult to conduct in-depth data analysis and trend prediction. Safety issues: When testing under high pressure, special attention should be paid to operational safety to prevent accidental injuries or equipment damage. Efficiency and cost: The testing process is cumbersome and time-consuming, resulting in low overall testing efficiency and increased production costs. Environmental adaptability: Different test environments (such as temperature and humidity) may affect the test results, and these variables need to be strictly controlled. In summary, the existing mobile phone mid-plate graded pressure-maintaining waterproof test method has problems such as complex operation, low degree of automation, inconvenient data management, and potential safety hazards.

[0004] In view of the above problems, the present invention proposes a graded pressure-maintaining and waterproof testing method and system for a mobile phone mid-plate, which simulates various underwater environmental conditions by precisely controlling different levels of pressure-maintaining standards, thereby evaluating the waterproof performance of the mobile phone mid-plate.

Low degree of automation: Due to reliance on manual operation, these methods have a low degree of automation, which may lead to operational errors and affect the consistency and reliability of the test results. Data recording and analysis: Manually recording test data is prone to errors, and it is difficult to conduct in-depth data analysis and trend prediction. Safety issues: When testing under high pressure, special attention should be paid to operational safety to prevent accidental injuries or equipment damage. Efficiency and cost: The testing process is cumbersome and time-consuming, resulting in low overall testing efficiency and increased production costs. Environmental adaptability: Different test environments (such as temperature and humidity) may affect the test results, and these variables need to be strictly controlled. In summary, the existing mobile phone mid-plate graded pressure-maintaining waterproof test method has problems such as complex operation, low degree of automation, inconvenient data management, and potential safety hazards.

[0076] In an embodiment of the present invention, a method and system for testing the graded pressure-maintaining waterproof performance of a mobile phone mid-plate are provided. The scheme simulates various underwater environmental conditions by precisely controlling the pressure-maintaining standards of different levels, thereby evaluating the waterproof performance of the mobile phone mid-plate.

[0077] According to a first aspect of an embodiment of the present invention, a method for testing the graded pressure-maintaining and waterproof properties of a mobile phone mid-plate is provided.

[0078] Figure 1 The present invention is a flowchart of a method for testing the graded pressure-maintaining and waterproof properties of a mobile phone mid-plate according to an embodiment of the present invention.

[0079] In one or more embodiments, preferably, the method for testing the graded pressure-maintaining waterproofness of a mobile phone mid-plate includes:

[0080] S101, selecting appropriate test equipment and setting corresponding test parameters according to the waterproof level of the mobile phone;

[0081] S102. Place the mobile phone in the test chamber and ensure that all connections are correct;

[0082] S103, starting the test process through the user interface, and the pressure control unit starts to apply pressure;

[0083] S104. During the set pressure holding time, continuously monitor the pressure changes to ensure the pressure is stable;

[0084] S105, after the pressure holding time is reached, gradually release the pressure and take the mobile phone out of the test cavity;

[0085] S106: Analyze the test results using data acquisition and analysis software to determine whether the mobile phone passes the waterproof test.

[0086] In an embodiment of the present invention, the existing mobile phone mid-plate graded pressure-maintaining waterproof test method mainly relies on manual or semi-automatic test processes. These methods usually involve placing the mobile phone mid-plate into a sealed test cavity, and then applying a certain water pressure or air pressure through an external device to simulate the pressure environment at different depths underwater. The tester needs to closely monitor the pressure changes, manually release the pressure after reaching the predetermined pressure holding time, and finally check whether there is water infiltration or other signs of damage in the mid-plate. The technical difficulties and key points of this method include precise control of pressure, accurate control of pressure holding time, low degree of automation, inconvenience in data recording and analysis, safety issues, and efficiency and cost considerations. In addition, different test environments (such as temperature and humidity) may affect the test results, so these variables need to be strictly controlled. Because the testing process is cumbersome and time-consuming, the overall test efficiency is low, which increases production costs.

[0087] Figure 2The present invention is a flowchart of selecting appropriate testing equipment in a method for testing the graded pressure-maintaining waterproofness of a mobile phone mid-plate in one embodiment of the present invention, and setting corresponding testing parameters according to the waterproofness level of the mobile phone.

[0088] like Figure 2 As shown, in one or more embodiments, preferably, the selecting of a suitable test device and setting of corresponding test parameters according to the waterproof level of the mobile phone specifically include:

[0090] S202, each test device has a preset waterproof safety margin;

[0091] S203, calculating a waterproof test parameter using a first calculation formula according to the waterproof safety margin and a preset margin of the waterproof specification;

[0092] The first calculation formula is:

[0093] F=YF×K

[0094] Among them, F is the waterproof test parameter, YF is the waterproof safety margin, and K is the preset margin of the waterproof specification.

[0095] In an embodiment of the present invention, it is first necessary to select a suitable test device. This includes setting up a preset set of test devices, each of which has a corresponding waterproof specification. For example, for IP67-rated equipment, it may be necessary to maintain pressure for a certain period of time at a certain water depth; while for IP68-rated equipment, it is necessary to maintain pressure at a deeper water depth or for a longer period of time. Each test device has a preset waterproof safety margin, which is to ensure that excessive pressure or damage is not caused to the device during the test. The waterproof test parameters are then calculated using the first calculation formula based on the waterproof safety margin and the waterproof specification preset margin. The first calculation formula is: F=YF×K, where F is the waterproof test parameter, YF is the waterproof safety margin, and K is the waterproof specification preset margin. In this way, it can be ensured that the waterproof performance of each test device meets the waterproof grade specification to which it belongs.

[0096] Figure 3 The present invention is a flowchart of placing a mobile phone in a test cavity and ensuring that all connections are correct in a method for testing the graded pressure-maintaining waterproofness of a mobile phone mid-plate according to an embodiment of the present invention.

[0101] S304, placing the mobile phone and the water immersion sensor together in the test cavity;

[0102] The second calculation formula is:

[0103] Zx>1.15×SZ

[0104] Among them, Zx is the minimum cavity area and SZ is the area occupied by the mobile phone.

[0105] In an embodiment of the present invention, it is first necessary to place the mobile phone in the test cavity and ensure that all connections are correct. This includes selecting a set of pre-set cavities and extracting the minimum cavity area that satisfies the second calculation formula. The second calculation formula is: Zx>1.15×SZ, where Zx is the minimum cavity area and SZ is the area occupied by the mobile phone. The width and length of the test cavity are selected according to the minimum cavity area, and the depth is pre-set and does not need to be adjusted. Then place the mobile phone and the water immersion sensor together in the test cavity. In this way, it can be ensured that the waterproof performance of each test device meets the waterproof grade specification to which it belongs.

[0106] Figure 4 It is a flow chart of starting the test process through a user interface and the pressure control unit starting to apply pressure in a method for testing the graded pressure-maintaining waterproofness of a mobile phone mid-plate according to an embodiment of the present invention.

According to the pre-set start interface, the pressurization time and the pressure holding time are set; the pressurization is automatically performed and the pressure change is detected. This method can ensure that the waterproof performance of each test device meets the waterproof grade specification to which it belongs.

[0111] Figure 5 It is a flow chart of a method for testing the graded pressure-maintaining waterproofness of a mobile phone mid-plate according to an embodiment of the present invention, which continuously monitors the pressure change within a set pressure-maintaining time to ensure the pressure is stable.

[0112] like Figure 5 As shown, in one or more embodiments, preferably, the pressure change is continuously monitored during the set pressure holding time to ensure pressure stability, specifically including:

[0113] S501, after setting the set pressure holding time, when it is determined online that the pressure change does not satisfy the third calculation formula, the pressure injection is increased;

[0114] S502, when the pressure injection reaches the preset current pressurization pressure and continues for the corresponding pressure holding time, the voltage is increased to the next pressurization pressure until the maximum pressurization pressure is reached;

[0115] S503, before reaching the maximum pressurization pressure, if the amount of water seepage detected under a certain current pressurization pressure does not satisfy the fourth calculation formula, gradually release the pressure and take the mobile phone out of the test cavity;

[0116] The third calculation formula is:

[0117] YS <DQ

[0118] Among them, YS is the pressure decay, and DQ is the current pressurization pressure;

[0119] The fourth calculation formula is:

[0120] SS <ZS

[0121] Among them, SS is the water seepage amount and ZS is the maximum water seepage margin.

[0122] In an embodiment of the present invention, first, a set pressure holding duration is set. Then, when it is determined online that the pressure change does not satisfy the third calculation formula, the injection of pressure is increased. The third calculation formula is: YS < DQ, where YS is the pressure decay and DQ is the current pressurization pressure. When the pressure injection reaches the preset current pressurization pressure and continues to reach the corresponding pressure holding duration, the voltage is increased to the next pressurization pressure until the maximum pressurization pressure is reached. Before reaching the maximum pressurization pressure, if the detected water seepage amount at a certain current pressurization pressure does not satisfy the fourth calculation formula, the pressure is gradually released and the mobile phone is taken out of the test cavity. The fourth calculation formula is: SS < ZS, where SS is the water seepage amount and ZS is the maximum water seepage margin. In this way, it can be ensured that the waterproof performance of each test device meets the waterproof grade specification to which it belongs.

[0123] Figure 6 It is a flowchart of gradually releasing pressure and taking the mobile phone out of the test cavity after reaching the pressure holding time in a method for grading pressure holding and waterproof testing of a mobile phone middle plate according to an embodiment of the present invention.

Then gradually release the pressure and take the mobile phone out of the test cavity. In this way, it can be ensured that the waterproof performance of each test device meets the waterproof grade specification to which it belongs.

[0128] Figure 7 It is a flowchart of analyzing the test results using data acquisition and analysis software to determine whether the mobile phone passes the waterproof test in a method for grading pressure holding and waterproof testing of a mobile phone middle plate according to an embodiment of the present invention.

If satisfied, the mobile phone is considered to have passed the waterproof test, otherwise, it is considered to have failed.

[0132] In the embodiment of the present invention, when performing the graded pressure-maintaining waterproof test method for the mobile phone mid-plate, the test results are analyzed using data acquisition and analysis software to determine whether the mobile phone has passed the waterproof test. First, the real-time collected water seepage data and pressurization data are obtained; then, a comparison is performed using the pre-set pressure analysis software to determine whether the pre-set constraint relationship between the water seepage data and the pressurization data is satisfied. If satisfied, the mobile phone is considered to have passed the waterproof test, otherwise it is considered to have failed. This method can ensure that the waterproof performance of each test device meets the waterproof grade specification to which it belongs.
