Description

Technical Field

[0001] This invention relates to the field of mobile phone pressure waterproof testing, specifically to a mobile phone pressure testing device and a mobile phone immersion pressure waterproof testing apparatus. Background Technology

[0002] With the diversification of mobile phone functions, users' demands for mobile phones to withstand humid and underwater environments are increasing. Waterproof performance testing is one of the key aspects of evaluating mobile phone reliability, and the requirements for waterproof design of mobile phones are becoming increasingly stringent, requiring continuous development of corresponding testing technologies. Existing mobile phone immersion testing equipment mainly suffers from the following problems: Insufficient pressure resistance: Most traditional immersion test equipment can only simulate normal or low-pressure underwater environments, making it difficult to meet high-pressure test requirements such as 8.53psi and above. This makes it impossible to fully verify the waterproof reliability of mobile phones in extreme underwater environments. For example, some ordinary immersion test chambers have a low upper limit of pressure resistance. When trying to increase the pressure, the chamber is prone to deformation, leakage, and other issues. Lack of visual monitoring: Traditional water immersion test equipment is mostly made of opaque materials, which makes it impossible for operators to clearly observe the inside of the water tank throughout the test, including whether there are water marks on the mobile phone, whether the UV solution flows abnormally, and whether there are leaks or bubbles at the seal. The test status can be intuitively judged without disassembling the equipment, which is crucial for the determination of the water immersion test results. Poor sealing reliability: The sealing structure is poorly designed, and commonly used sealing methods are prone to failure under high pressure, which can lead to gas or moisture leakage during the test. This not only disrupts the stability of the test environment but also makes the test results inaccurate, making it impossible to accurately determine whether the phone truly has the corresponding waterproof capability. Low testing efficiency: Most devices can only test a few phones at a time. For the quality inspection needs of large-scale mobile phone manufacturers, the testing efficiency is difficult to meet, which increases the time and labor costs of enterprises. Poor accuracy in test solution preparation: Current tests mostly rely on manual preparation of UV solutions using tools such as graduated cylinders and balances. This is prone to problems such as reading errors, liquid adhering to the walls, and solvent evaporation due to temperature and humidity, resulting in ratio deviations (accuracy is only ±5%~±10%). There are also large differences in preparation between different batches and different operators, leading to problems such as "insufficient concentration causing missed detection" and "excessive concentration causing corrosion to mobile phones / water tanks". The testing standards are not uniform. Insufficient pressure control accuracy: The pressure monitoring and control device has low accuracy, which makes it impossible to achieve precise control and real-time monitoring of pressure. The pressure fluctuates greatly during pressurization and pressure holding, which cannot accurately simulate the real extreme underwater pressure environment and affects the accuracy of test results. Lack of safety protection: The lack of a sound overpressure protection mechanism means that when the pressurization system malfunctions, the pressure sensor fails, or the operator misoperates, the pressure inside the chamber may exceed the design limit, causing serious accidents such as the rupture of the sealed chamber and harming surrounding personnel and equipment. Poor operability and traceability: Handling of mobile phones depends on manual operation, which can easily damage the phones due to improper operation; there are no data records for solution preparation, pressure changes, etc., so it is impossible to trace the cause when there is an anomaly, which is not conducive to the optimization of the test process; The shortcomings of these existing technologies mean that mobile phone waterproofing performance testing cannot meet the industry's requirements for high-quality, high-reliability mobile phones, and also restrict the further development of mobile phone waterproofing design technology. Therefore, there is an urgent need for a mobile phone immersion pressure testing device and method with strong pressure resistance, reliable sealing, high testing efficiency, precise pressure control, and comprehensive safety protection to solve the many problems existing in the current technologies. Summary of the Invention

[0003] The technical problem this invention aims to solve is the insufficient pressure resistance, poor sealing, low efficiency, and low pressure control accuracy of existing mobile phone immersion testing equipment. This invention provides a mobile phone pressurization device and a mobile phone immersion pressurization waterproof testing apparatus. It employs a pressurized water tank equipped with a solution injection component and a pressurization component to achieve pressurization testing of the mobile phone. A peristaltic pump and a liquid level detection sensor are integrated into a high-precision metering module to achieve automatic solution preparation, preset mixing parameters, and a metering accuracy of ±0.1%. The system automatically completes liquid suction, mixing, and stirring, records the preparation data, and avoids human error. An additional pressing machine is also included. The structure, locking mechanism, and sealing ring are designed for reliable sealing, ensuring stable pressure after pressurization. The pressurization components include an intelligent adjustment module, a two-stage pressure reducing valve (0.15 MPa control), and a high-precision pressure sensor (0.001 psi accuracy) for real-time pressure monitoring. A mechanical safety valve (0.1 MPa start-up pressure) and pressure anomaly alarm are included, with automatic venting and test termination in case of overpressure. An automated testing process is implemented: a three-axis module mechanical gripper handles the mobile phone, pressurizes to 8.53 psi and holds for 30 minutes, and judges the results based on pressure stability (±2% range) and leakage, improving efficiency and consistency to address the defects caused by existing technologies.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solutions: In a first aspect, a mobile phone pressurization device includes a pressurization water tank, a lid detachably mounted on the top of the pressurization water tank, an outer frame of the pressurization water tank, a fixing frame mounted on the outer side of the lid, and an opening and closing cylinder connected to the fixing frame mounted on the outer frame of the tank. The solution injection assembly is connected to the pressurized water tank via a pipeline; The pressurization component is connected to the pressurization water tank via a second pipeline; A pressure sensor is installed on the pressurized water tank, a clamping mechanism and a liquid level sensor are installed on the outer frame of the tank, and a locking mechanism is installed on the fixed frame; The control terminal is electrically connected to the opening and closing cylinder, the solution injection assembly, the pressurization assembly, the pressure sensor, the clamping mechanism, the liquid level sensor, and the locking mechanism.

[0006] In the aforementioned mobile phone pressurization device, the solution injection component includes a solution tank and a peristaltic pump connected in sequence through the first pipeline, the other end of the first pipeline is connected to the pressurization water tank, and a first interface connected to the first pipeline is provided on one side of the pressurization water tank. The control terminal controls the peristaltic pump, turns it on, and allows the solution to enter the pressurized water tank. The liquid level sensor detects the liquid level in real time and transmits the data to the control terminal. The control terminal controls the peristaltic pump according to preset mixing parameters, achieving a metering accuracy of ±0.1%. It automatically completes liquid aspiration, mixing, and stirring, records mixing data, avoids human error, realizes automatic solution mixing, and integrates a high-precision metering module.

[0007] The aforementioned mobile phone pressurization device includes a pressure regulator and a secondary pressure reducing valve connected in sequence through a second pipeline. The other end of the second pipeline is connected to the pressurization water tank. A second interface connected to the second pipeline is provided on one side of the pressurization water tank. A safety valve is installed on the second pipeline. The control terminal controls the pressure regulator and the secondary pressure reducing valve. The secondary pressure reducing valve controls the pressure to 0.15 MPa. The pressure sensor has an accuracy of 0.001 psi and monitors the pressure in real time to achieve precise pressurization and safety protection. It can also be equipped with a mechanical safety valve (starting pressure 0.1 MPa) and a pressure abnormality alarm. It automatically vents air when the pressure is too high to stop the test.

[0008] In the aforementioned mobile phone pressurization device, a cleaning nozzle is installed on the pressurization water tank.

[0009] In the aforementioned mobile phone pressurization device, a silicone rubber sealing ring is installed on the top of the pressurization water tank. The silicone rubber sealing ring is selected from Shore 40A. The top of the pressurization water tank is provided with a groove for placing the silicone rubber sealing ring. Through the coordinated design of the pressing mechanism, the locking mechanism and the silicone rubber sealing ring, it is ensured that the pressure remains stable and unchanged after the device is pressurized.

[0010] The aforementioned mobile phone pressurization device, wherein the pressurization water tank and the tank cover are made of high-strength transparent PMMA material. The pressurization water tank is a cuboid with a wall thickness of 40mm, an internal length of 720mm, and a width of 420mm. It is made of acrylic material and can hold 12 mobile phones. The maximum pressure is 10.67psi, with a safety factor of 1.25, taking into account light transmission for observation, high pressure resistance, and sealing reliability.

[0011] In a second aspect, a mobile phone immersion and pressurized waterproof testing device includes a frame and a conveying mechanism mounted on the frame, the mobile phone pressurizing device mentioned in the first aspect, and a three-axis material handling mechanism. The conveying mechanism includes a conveying component and an output component respectively disposed on both sides of the mobile phone pressurization device; The three-axis material handling mechanism includes a guide rail disposed on the upper side of the mobile phone pressurizing device, with its two ends extending to the conveying component and the output component respectively, and a three-axis module mechanical claw movably mounted on the bottom of the guide rail; The control terminal controls the conveying component, the output component, and the three-axis module mechanical gripper, respectively.

[0012] The aforementioned mobile phone immersion and pressure waterproof testing device, wherein the control terminal includes a touch screen and a controller mounted on the touch screen; The controller is electrically connected to the touch screen, the mobile phone pressurization device, the conveying component, the output component, and the three-axis module mechanical gripper. The three-axis module mechanical gripper picks up and places the mobile phone, pressurizes it to 8.53 psi and holds it for 30 minutes. The results are judged based on pressure stability (±2% range) and leakage, thereby improving efficiency and consistency.

[0013] Based on the above technical solution, this mobile phone pressurization device and mobile phone immersion pressurization waterproof testing device can solve the four core problems of existing testing equipment: insufficient pressure resistance, inaccurate solution ratio, low efficiency, and poor safety. Through modular design, it achieves high-precision, automated, and high-safety mobile phone waterproof performance testing. The specific improvements are as follows: I. Acrylic Water Tank Structural Design: The pressurized water tank is made of high-strength transparent polymethyl methacrylate (PMMA, commonly known as acrylic), which has a light transmittance of over 90%, allowing for full visualization of the phone leakage status inside the tank. It also possesses excellent pressure resistance and corrosion resistance, preventing aging and swelling issues caused by prolonged contact with water and UV solutions. The pressurized water tank has a rectangular structure with precisely designed internal dimensions of 720mm × 420mm. Combined with a professional phone carrying basket, it can accommodate 12 phones for parallel testing, increasing efficiency by more than 10 times compared to traditional single-station equipment, thus meeting the needs of mass production testing of mobile phones. The pressurized water tank wall thickness is set at 40mm. Combined with the mechanical properties of PMMA, the pressurized water tank is designed to withstand a maximum pressure of 10.67psi with a safety factor of 1.25, providing sufficient safety margin for the 8.53psi test pressure in this case, preventing deformation of the tank under high pressure. In terms of sealing reliability, an annular groove is opened on the pressurized water tank, with a silicone rubber sealing ring of Shore hardness 40A embedded inside. This silicone rubber has both elasticity and wear resistance, and can tightly fit the contact surface between the tank cover and the pressurized water tank. It can withstand the humid environment for a long time without the risk of aging and cracking. The sealing structure adopts a double fixation of "groove embedding + locking tongue". After the tank cover is closed, it ensures that the sealing ring is fully compressed, preventing gas and liquid leakage and ensuring the stability of the test environment. II. Automatic preparation of test solutions: To address the issues of poor accuracy and low batch consistency in manually prepared UV solutions, this solution employs an integrated fully automated solution preparation module consisting of a high-precision peristaltic pump and a liquid level detection sensor. Before use, the ratio parameters of solvent (deionized water) and UV reagent are preset through the device control interface. After startup, the peristaltic pump accurately extracts the solvent and UV reagent according to the preset parameters, ensuring a metering accuracy of ±0.1%, which is far superior to the ±5%~±10% accuracy of manual preparation. III. Pressurization and Safety Control System: The pressurization system employs a three-tiered control logic of "intelligent regulation + precise pressure reduction + real-time monitoring." Core components include an intelligent pressure regulator with a rated output pressure of 0.5 MPa, a two-stage pressure reducing valve, and a digital pressure sensor with an accuracy of 0.001 psi. During testing, compressed air is first initially stabilized by the intelligent pressure regulator, and then precisely reduced to 0.15 MPa (the appropriate input value for the 8.53 psi test pressure) via the two-stage pressure reducing valve, preventing pressure fluctuations caused by direct high-pressure input. The digital pressure sensor, installed on the pressurization tank, collects real-time pressure data from within the tank and uploads it to the control terminal. When the pressure reaches 8.53 psi, the pressure sensor immediately sends a signal to close the intake valve, initiating the pressure holding phase. During this phase, pressure fluctuations are strictly controlled within ±2% psi to ensure the accuracy of simulating extreme underwater pressure environments. The system features a triple safety protection system: First, a mechanical safety valve is installed on the pressurization pipeline (second pipeline) with a set opening pressure of 0.1 MPa (approximately 14.5 psi). If the system pressure exceeds the limit, the safety valve automatically opens to release air, preventing the pressurization tank from rupturing due to excessive pressure. Second, a pressure sensor monitors the pressure drop rate in real time. If a rapid pressure drop occurs outside the depressurization process (such as a leaking seal), an audible and visual alarm is immediately triggered, the test is stopped, and the air release valve is activated to release the pressure inside the tank. Third, a secondary pressure reducing valve limits the input pressure to 0.15 MPa, preventing the risk of high-pressure input from the source. In addition, the equipment automatically performs functional tests on key components (valves, sensors) of the pressurization system before each startup to ensure fault-free operation. IV. Multi-station automated testing process: The entire testing process is automated and requires no manual intervention: In the initial preparation stage, the operator places the mobile phones to be tested into a special basket (3 phones per basket). The basket is then conveyed to the working range of the three-axis module picking mechanism via a conveying component. The three-axis module's mechanical claw picks up the basket and places it into the pressurized water tank along a preset trajectory, avoiding damage to the phones caused by manual handling. After the phones are placed, the tank lid automatically closes and locks, and the solution injection component is activated, dispensing a sufficient amount of UV solution into the pressurized water tank as needed to ensure that the phones are completely submerged.

[0014] The technical solution provided by the present invention, which includes a mobile phone pressurization device and a mobile phone immersion water pressure waterproof testing apparatus, has the following technical effects: The system employs a pressurized water tank equipped with a solution injection component and a pressurization component to perform pressurization testing on mobile phones. A peristaltic pump and a liquid level detection sensor are integrated into a high-precision metering module for automatic solution preparation. Preset mixing parameters and a metering accuracy of ±0.1% are used to automatically complete liquid aspiration, mixing, and stirring, recording the preparation data and mitigating human error. Added clamping, locking, and sealing rings ensure reliable sealing, guaranteeing stable pressure after pressurization. The pressurization component includes an intelligent adjustment module, a two-stage pressure reducing valve (0.15 MPa control), and a high-precision pressure sensor (0.001 psi accuracy) for real-time pressure monitoring. A mechanical safety valve (0.1 MPa start-up pressure) and pressure anomaly alarm are included, automatically venting and stopping the test in case of overpressure. The system achieves an automated testing process: a three-axis mechanical gripper handles the mobile phone, pressurizes to 8.53 psi, holds the pressure for 30 minutes, and determines the results based on pressure stability (±2% range) and leakage, improving efficiency and consistency.

[0022] like Figure 1-2 As shown, in a first aspect, a mobile phone pressurization device includes a pressurization water tank 100, a lid 101 detachably mounted on the top of the pressurization water tank 100, an outer frame 102 mounted around the pressurization water tank 100, a fixing frame 103 mounted on the outer side of the lid 101, and an opening and closing cylinder 104 connected to the fixing frame 103 mounted on the outer frame 102. The solution injection component is connected to the pressurized water tank 100 via a pipeline; The pressurization component is connected to the pressurization water tank 100 via a second pipeline; A pressure sensor 105 is installed on the pressurized water tank 100, a clamping mechanism and a liquid level sensor 107 are installed on the outer frame 102 of the tank, and a locking mechanism is installed on the fixed frame 103. The control terminal is electrically connected to the opening and closing cylinder 104, the solution injection assembly, the pressurization assembly, the pressure sensor 105, the clamping mechanism, the liquid level sensor 107, and the locking mechanism.

[0023] The clamping mechanism includes a clamping cylinder 106 installed on the outer frame 102 of the housing, and a clamping locking tongue 111 matching the clamping cylinder 106 is provided on the fixed frame 103. The locking mechanism includes a locking cylinder 108 mounted on the fixed frame 103, and a locking tongue 109 matching the locking cylinder 108 is provided on the outer frame 102 of the housing. The control terminal controls the connecting clamping cylinder 106 and the locking cylinder 108 respectively.

[0024] The solution injection assembly includes a solution tank and a peristaltic pump connected in sequence through a first pipeline. The other end of the first pipeline is connected to a pressurized water tank 100. A first interface connected to the first pipeline is provided on one side of the pressurized water tank 100. The control terminal controls the peristaltic pump and starts it up. The solution enters the pressurized water tank 100. The liquid level sensor 107 detects the liquid level in real time and transmits it to the control terminal. The control terminal controls the peristaltic pump to work according to the preset mixing parameters, so that the metering accuracy is ±0.1%. It automatically completes liquid aspiration, mixing, stirring, and recording of preparation data, avoiding human error, realizing automatic solution preparation, and integrating a high-precision metering module.

[0025] The pressurization assembly includes a pressure regulator and a secondary pressure reducing valve connected in sequence through a second pipeline. The other end of the second pipeline is connected to the pressurization water tank 100. A second interface connected to the second pipeline is provided on one side of the pressurization water tank 100. The control terminal connects to a pressure regulator and a secondary pressure reducing valve. The secondary pressure reducing valve controls the pressure at 0.15 MPa. The pressure sensor 105 has an accuracy of 0.001 psi, which monitors the pressure in real time to achieve precise pressurization and safety protection. It can also be equipped with a mechanical safety valve (starting pressure 0.1 MPa) and a pressure abnormality alarm. It automatically releases air when the pressure is too high, thus stopping the test.

[0026] The pressurized water tank 100 is equipped with a cleaning nozzle 110, which can be connected to a water pipe to clean the inside of the pressurized water tank 100.

[0027] The pressurized water tank 100 is equipped with a silicone rubber sealing ring on its top. The silicone rubber sealing ring has a Shore hardness of 40A. This hardness of silicone rubber has both elasticity and wear resistance. It can fit tightly against the contact surface between the water tank cover 101 and the tank body. It can withstand the humid environment for a long time without the risk of aging and cracking. The top edge of the pressurized water tank 100 is provided with a groove for placing the silicone rubber sealing ring. Through the coordinated design of the pressing mechanism, locking mechanism and silicone rubber sealing ring, it is ensured that the pressure is stable and does not change after the equipment is pressurized.

[0028] The pressurized water tank 100 and the tank cover 101 are made of high-strength transparent PMMA material. The pressurized water tank 100 is a cuboid with a wall thickness of 40mm, an internal length of 720mm, and a width of 420mm. It is made of acrylic material and can hold 12 mobile phones. The pressure limit is 10.67psi, the safety factor is 1.25, and it takes into account light transmission for observation, high pressure resistance, and sealing reliability.

[0029] The specific usage process of a mobile phone pressurization device is as follows: The phone is placed in the pressurized water tank 100. The opening and closing cylinder 104 retracts the cover 101 to close. The cover 101 is pressed tightly by the pressing cylinder 106. Then the locking cylinder 108 extends to cooperate with the locking tongue 109 to lock. The pressurized water tank 100 is completely sealed. It adopts a double sealing and fixation of "sealing ring embedding + locking tongue". After the cover 101 is closed, the sealing ring is fully compressed to prevent gas and liquid leakage and ensure the stability of the test environment. Subsequently, the preset ratio parameters of solvent (deionized water) and UV reagent are operated via the terminal. A high-precision peristaltic pump and liquid level sensor control the solution accuracy. After startup, the peristaltic pump accurately extracts the solvent and UV reagent according to the preset parameters, ensuring a measurement accuracy of ±0.1%. After the solution is added, internal pressurization begins. The pressurization system employs a three-level control logic of "intelligent adjustment + precise pressure reduction + real-time monitoring." Core components include an intelligent pressure regulating module with a rated output pressure of 0.5 MPa, a two-stage pressure reducing valve, and a digital pressure sensor 105 with an accuracy of 0.001 psi. During testing, compressed air is first initially stabilized by the intelligent pressure regulator before being supplied with air. The pressure is precisely reduced to 0.15 MPa (the appropriate input value for the 8.53 psi test pressure) by a two-stage pressure reducing valve to avoid pressure fluctuations caused by direct high-pressure input. A digital pressure sensor 105 is installed next to the pressurized water tank 100 to collect the pressure data in the tank in real time and upload it to the control terminal. When the pressure rises to 8.53 psi, the pressure sensor 105 immediately sends a signal to close the air intake valve and enter the pressure holding stage. During the pressure holding process, the pressure fluctuation is strictly controlled within ±2% psi to ensure the accuracy of simulating extreme underwater pressure environments. Another pressure sensor 105 is installed on the pressurized water tank 100 to monitor the pressure fluctuation range simultaneously. The test requires holding the pressure for half an hour. After the test is completed, the pressure testing mechanism starts to release the pressure. After the pressure is released to a certain level, the locking mechanism is activated, the water tank cover is opened, and the phone is taken out.

[0030] like Figure 3-4 As shown, in the second aspect and the second embodiment, a mobile phone immersion and pressurization waterproof testing device is provided, which includes a frame 200 and a conveying mechanism, a mobile phone pressurization device in the first aspect, and a three-axis material handling mechanism 500 mounted on the frame 200. The conveying mechanism includes a conveying component 300 and an output component 400 respectively disposed on both sides of the mobile phone pressurization device; The three-axis material handling mechanism 500 includes a guide rail 501 disposed on the upper side of the mobile phone pressurizing device and extending to the conveying component 300 and the output component 400 at both ends, and a three-axis module mechanical claw 502 movably mounted on the bottom of the guide rail 501. The control terminal controls the connected conveying component 300, the output component 400, and the three-axis module mechanical gripper 502 respectively.

[0031] The aforementioned mobile phone immersion and pressure waterproof testing device includes a control terminal comprising a touch screen 600 and a controller mounted on the touch screen 600. The controller is electrically connected to the touch screen 600, the mobile phone pressurization device, the conveying component 300, the output component 400, and the three-axis module mechanical gripper 502.

[0032] The testing process using the aforementioned mobile phone immersion and pressure waterproof testing device is as follows: The phones to be tested are placed in a dedicated basket (3 phones per basket), and the basket is placed on the conveying assembly 300. The conveying assembly 300 transports the phones to the working range of the three-axis material handling mechanism 500. The three-axis module mechanical claw 502 picks up the basket and places it into the phone pressurization device according to a preset trajectory. A total of four baskets are used, allowing a total of 12 phones to be tested simultaneously. After the phones are placed, the lid 101 is automatically closed by the opening and closing cylinder 104 and locked by the pressing and locking mechanisms. The solution injection assembly is activated, and sufficient UV solution is prepared as needed and injected into the pressurization tank 100 through a peristaltic pump to ensure that the phones are completely submerged. After the test is completed, the pressing and locking mechanisms are opened, and the lid 101 is automatically opened by the opening and closing cylinder 104, and the pressure is released. The three-axis material handling mechanism 500 removes the dedicated basket and places it on the output assembly 400 for the operator to remove.

[0033] The pressurization process follows a "pressurization-holding-depressurization" procedure: after pressurizing to 8.53 psi, the pressure is held for 30 minutes. During this holding period, the operator can set a camera to record and observe whether the phone leaks (e.g., bubbles appear in the pressurized water tank 100 or UV solution seeps into the phone and causes color changes). Simultaneously, the control terminal displays the pressure curve in real time. After the test, the system automatically opens the vent valve to release pressure. Once the pressure reaches zero, the water tank cover 101 opens, and the three-axis module robotic gripper 502 removes the phone and places it in the finished product basket, completing a single test. The entire process takes approximately 40 minutes (including solution preparation) and can run continuously without interruption. All test data (pressure changes, preparation parameters, result determination) is automatically stored in the database, supporting export and traceability, significantly improving testing efficiency and data integrity. Automatic drainage and water tank cleaning are supported when the test solution is replaced, ensuring that the newly injected solution is not contaminated.

[0034] In summary, the present invention provides a mobile phone pressurization device and a mobile phone immersion pressurization waterproof testing device. It employs a pressurized water tank equipped with a solution injection component and a pressurization component to perform pressurization testing on the mobile phone. A peristaltic pump and a liquid level detection sensor are integrated into a high-precision metering module to achieve automatic solution mixing. Preset mixing parameters are used, with a metering accuracy of ±0.1%. The device automatically completes liquid suction, mixing, and stirring, and records the mixing data, avoiding human error. The added clamping mechanism, locking mechanism, and sealing ring ensure reliable sealing, guaranteeing stable pressure after pressurization. The pressurization component includes an intelligent adjustment module, a two-stage pressure reducing valve (0.15 MPa control pressure), and a high-precision pressure sensor (0.001 psi accuracy) to monitor pressure in real time. A mechanical safety valve (0.1 MPa start-up pressure) and pressure abnormality alarm are included, automatically venting and stopping the test in case of overpressure. The automated testing process is achieved: a three-axis module mechanical gripper picks up and places the mobile phone, pressurizes it to 8.53 psi, and holds the pressure for 30 minutes. The results are judged based on pressure stability (±2% range) and leakage, improving efficiency and consistency.
