[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0058] Example 1
[0059] Please refer to Figure 1-2 Embodiment 1 of the present invention provides a compression testing device, the device including a compression mechanism 1, a monitoring module 2 and a control module 3;
[0060] The extrusion mechanism 1 and the monitoring module 2 are respectively connected to the control module 3 to ensure efficient and accurate information exchange between the modules.
[0061] The extrusion mechanism 1, as the actuating component of the entire device, plays a crucial role under the precise control of the control module 3. Once the test process begins, the extrusion mechanism 1 applies extrusion force to the terminal 9, which is in the test state, according to the instructions issued by the control module 3. This extrusion operation is not arbitrary but strictly follows the parameters set by the control module 3, thereby ensuring the standardization and consistency of the extrusion process.
[0062] Under the control of module 3, monitoring module 2 undertakes the crucial task of data acquisition. Before the compression operation on the test terminal 9, monitoring module 2 activates its image acquisition function to capture initial images of terminal 9 before compression, recording detailed information such as its appearance and structural features in image form. After the compression operation is completed, monitoring module 2 again plays its role, capturing deformed images of terminal 9 after compression, clearly showing the morphological changes that occurred after the compression. These initial and deformed images provide rich and crucial raw data for subsequent data analysis.
[0063] The control module 3 possesses powerful data processing and control capabilities. It receives the initial and deformed images of the terminal 9 collected by the monitoring module 2, and uses advanced image recognition and data analysis technologies to accurately locate points of interest (usually feature points on the terminal surface or points in known locations, such as the charging indicator light on a smart ring) within the images. It then acquires the three-dimensional coordinates of these points of interest before and after extrusion. Based on this three-dimensional coordinate data, the control module 3 calculates the deformation of the terminal 9 during the extrusion process. After calculating the deformation, the control module 3 generates detailed and accurate extrusion test results according to preset rules and standards, providing a scientific and reliable basis for the entire testing process.
[0064] For example, suppose the selected points of interest have three-dimensional coordinates of (x1, y1, z1) before extrusion and (x2, y2, z2) after extrusion.
[0065] Calculate the 3D coordinate deviation of the point of interest using the following formula:
[0066] Δr=(x2-x1, y2-y1, z2-z1);
[0067] Continue to calculate and determine the deformation amount using the following formula:
[0068] Δd = √(x2 - x1) 2 +(y2-y1) 2 +(z2-z1) 2 .
[0069] The extrusion testing device provided in this invention offers significant advantages over traditional manual extrusion testing methods. Firstly, regarding testing accuracy and repeatability, traditional manual extrusion testing often struggles to precisely control the extrusion force and speed. Significant differences can exist between different operators and even within the same operator at different times, directly compromising the accuracy and repeatability of test results. In contrast, the extrusion testing device in this invention, through automated control technology, can precisely control the extrusion force and speed according to preset parameters, ensuring consistent conditions for each extrusion operation. This significantly improves the accuracy and repeatability of test results, effectively overcoming the limitations of manual operation in terms of precision.
[0070] Secondly, regarding testing efficiency, traditional manual extrusion testing requires operators to manually complete multiple steps such as extrusion and data recording. This process is not only cumbersome but also time-consuming, significantly limiting the improvement of testing efficiency. In contrast, the extrusion testing device in this invention adopts an automated operation mode, reducing manual intervention. The various modules work collaboratively, enabling the extrusion testing process to be completed quickly and efficiently, greatly improving testing efficiency and successfully solving the problem of time-consuming manual operations.
[0071] Furthermore, regarding data recording and processing, traditional manual extrusion testing requires operators to manually record test data. This process is not only prone to recording errors but may also result in incomplete data recording, affecting the accuracy and reliability of the test results. In contrast, the extrusion testing device in this embodiment of the invention allows the control module to automatically calculate the deformation amount and directly generate test results based on the initial and deformation images acquired by the monitoring module from terminal 9. This avoids the errors and incompleteness that may occur during manual data recording, ensuring the accuracy and completeness of the test data.
[0072] This intelligent extrusion testing device, with its high precision, high efficiency, and reliable data processing capabilities, not only provides a more scientific and accurate testing method for extrusion testing, improving the overall quality and level of testing, but also provides more reliable quality inspection assurance for the production process of wearable terminal devices. By conducting rigorous extrusion tests on wearable terminal devices, potential problems in the design and manufacturing process can be identified in a timely manner, ensuring the reliability and durability of products under various complex environments, thereby enhancing the product's market competitiveness and meeting consumer demand for high-quality products.
[0073] Please refer to this again. Figure 1 In one embodiment of this invention, the extrusion mechanism 1 includes two extrusion components with identical structures;
[0074] The two extrusion components are symmetrically and stably arranged on the left and right sides of the terminal 9 in terms of spatial layout. This arrangement can ensure that the extrusion force on the terminal 9 is evenly distributed during the extrusion test, and avoid the impact of uneven force on the accuracy and reliability of the test results.
[0075] The extrusion assembly consists of three parts: a fixing unit 11, a driving unit 12, and an extrusion unit 13.
[0076] The main function of the fixing unit 11 in the entire extrusion assembly is to firmly fix the drive unit 12 in a predetermined position, provide a stable working platform for the drive unit 12, and ensure that the drive unit 12 will not be affected by shaking or displacement during operation, thereby ensuring the stability and reliability of the entire extrusion assembly.
[0077] The drive unit 12 is mounted on the fixed unit 11 and can operate precisely according to given parameters and instructions. The drive unit 12 is connected to the extrusion unit 13 via a specific mechanical connection or transmission method. Its main function is to provide the necessary power to the extrusion unit 13, driving it to move according to a predetermined trajectory and speed. Under the precise control of the control module 3, the drive unit 12 can flexibly adjust the magnitude and frequency of its output power according to different testing requirements to achieve different degrees of extrusion operation on the terminal 9.
[0078] The extrusion unit 13 is the part of the extrusion assembly 1 that directly contacts and applies force to the terminal 9. It is typically made of a high-strength, wear-resistant material with a certain degree of flexibility to ensure that sufficient extrusion force is effectively applied to the terminal 9 during the extrusion process without causing excessive damage. Driven by the drive unit 12, the extrusion unit 13 contacts the terminal 9 in a predetermined direction and with predetermined force, continuously applying extrusion force to cause the terminal 9 to deform accordingly under the extrusion action. This provides the necessary conditions for the subsequent monitoring module 2 to acquire images and for the control module 3 to calculate the deformation.
[0079] This meticulously designed extrusion mechanism 1, through the coordinated work of the fixed unit 11, the drive unit 12 and the extrusion unit 13, and the symmetrical arrangement of the two extrusion components on both sides of the terminal 9, can achieve precise, stable and uniform extrusion operation on the terminal 9, laying a solid foundation for the efficient operation and accurate testing of the entire extrusion testing device.
[0080] Please refer to this again. Figure 1 In one embodiment of this invention, the device is further optimized and improved in terms of its overall architecture by adding an additional support base 4.
[0081] The support base 4 is designed to provide a stable platform for the terminal 9 to be tested. Functionally, the support base 4 performs two main tasks. Firstly, it provides load-bearing support, using its robust structure to firmly hold the terminal 9, ensuring it won't slip or shift due to its own weight or the force of compression during the entire compression test, thus guaranteeing the continuity and stability of the test process. Secondly, it provides positioning. The surface or interior of the support base 4 is equipped with specialized positioning structures or markings that match specific parts or shape features of the terminal 9, accurately fixing it in a preset position. This precise positioning not only ensures that the terminal 9 experiences uniform force during compression, avoiding errors in test results due to positional deviations, but also facilitates the monitoring module 2 in acquiring images of the terminal 9 before and after compression at a fixed position, providing a reliable data basis for the subsequent control module 3 to accurately calculate the deformation.
[0082] In summary, the support base 4, as an important component of this extrusion testing device, provides a solid guarantee for the stable testing of the terminal 9 through its reliable load-bearing and precise positioning functions, and effectively improves the performance of the entire extrusion testing device and the accuracy of the test results.
[0083] Please refer to this again. Figure 1-2 and in conjunction with references Figure 3 In one embodiment of this invention, the device has been further optimized and expanded based on the original structure, with the addition of a dripping mechanism 5 to enrich the testing functions of the device and meet more diverse testing needs.
[0084] The dripping mechanism 5 is communicatively connected to the control module 3. This communication connection enables the dripping mechanism 5 to operate in an orderly manner under the precise control of the control module 3, achieving automated and intelligent operation. The control module 3 can send various commands to the dripping mechanism 5, such as starting dripping, stopping dripping, adjusting dripping speed and dripping volume, thereby ensuring that the dripping process strictly follows the preset parameters.
[0085] The core component of the dripping mechanism 5 is the dripping unit 51, whose position is carefully planned and placed directly above the terminal 9. This layout design has significant advantages, ensuring that the corrosive liquid dripping from the dripping unit 51 lands accurately on the surface of the terminal 9, avoiding the corrosive liquid from dripping to other parts due to positional deviation, which would affect the accuracy and reliability of the test results.
[0086] The dripping unit 51 is capable of precisely controlling the dripping process. It is typically equipped with high-precision dripping control devices, such as micro-pumps and solenoid valves. These devices, under the command of the control module 3, can precisely control the outflow rate and flow rate of the corrosive liquid. When a dripping operation is required, the control module 3 issues a corresponding command, and the micro-pump or solenoid valve in the dripping unit 51 starts working, dripping the corrosive liquid stored in a specific container onto the surface of the terminal 9 according to the set parameters. The choice of corrosive liquid depends on the specific test requirements; it is a weakly acidic or alkaline chemical solution used to simulate the use of the terminal 9 in different harsh environments, such as simulating human sweat on the terminal, thereby detecting changes in its performance after corrosion, such as peeling of the outer coating and decreased structural strength, facilitating a more comprehensive test of the terminal's resistance to deformation.
[0087] Furthermore, the design of the dripping mechanism 5 fully considers safety and environmental protection. The dripping unit 51 typically employs a sealed design to prevent leakage of corrosive liquid and avoid harm to the surrounding environment and operators. Simultaneously, the device is equipped with a corresponding waste liquid collection and treatment system to properly collect and treat any remaining corrosive liquid after dripping, ensuring compliance with environmental protection requirements.
[0088] In summary, the addition of the dripping mechanism 5 further expands and enhances the functionality of the extrusion testing device. Through collaborative work with the control module, it enables comprehensive performance testing of the terminal 9 under the dual effects of corrosion and extrusion, providing a more comprehensive and accurate quality testing method for the research and development and production of wearable terminal devices and other products.
[0089] Please refer to this again. Figure 1 and Figure 3 In one embodiment of this invention, the dripping mechanism 5 is additionally equipped with a Y-direction moving component 52 and an X-direction moving component 53 on the basis of the original structure. The addition of these two components greatly expands the operational flexibility and testing coverage of the dripping mechanism 5.
[0090] From an overall layout perspective, the dripping mechanism 5 is cleverly positioned atop the X-direction moving component 53. This design allows the dripping mechanism 5 to flexibly adjust its position in the X direction of the horizontal plane by utilizing the movement function of the X-direction moving component 53. Furthermore, the X-direction moving component 53 itself does not operate independently; it is securely mounted on the Y-direction moving component 52, forming a precise system with two-dimensional movement capabilities on the horizontal plane.
[0091] Specifically, under the precise control of the control module 3, the Y-direction moving component 52 generates a stable and controllable power output, driving the connected X-direction moving component 53 and the dripping unit 51 mounted on the X-direction moving component 53 to move smoothly and precisely in the Y-direction of the horizontal plane. The Y-direction moving component 52 typically employs a combination of a high-precision linear guide and a drive motor. The linear guide provides low-friction, high-precision guidance support for the movement, ensuring the straightness and stability of the movement process; the drive motor precisely controls the speed and displacement of the movement according to the instructions issued by the control module 3, achieving accurate positioning of the dripping unit 51 in the Y-direction.
[0092] The X-direction moving component 53 also possesses highly precise movement control capabilities. It is mounted on the Y-direction moving component 52 and, under the control of the control module 3, can independently drive the dripping unit 51 to move in the X-direction of the horizontal plane. The structural design of the X-direction moving component 53 is similar to that of the Y-direction moving component 52, also employing a combination of linear guide rails and a drive motor. However, its parameter settings and control strategies are optimized and adjusted according to the movement requirements in the X-direction to ensure the movement accuracy and response speed of the dripping unit 51 in the X-direction.
[0093] Through the coordinated operation of the Y-direction moving component 52 and the X-direction moving component 53, the dripping unit 51 can achieve omnidirectional and high-precision movement on the horizontal plane. This two-dimensional movement capability allows the dripping unit 51 to flexibly adjust the position of the dripping corrosive liquid according to different test requirements. For example, when testing the corrosion resistance of different parts of the terminal 9, the control module 3 can precisely control the Y-direction moving component 52 and the X-direction moving component 53 according to the preset test plan to move the dripping unit 51 to the designated position of the terminal 9, and then drip the corrosive liquid for testing. This precise dripping positioning method not only improves the accuracy and reliability of the test, but also avoids test errors caused by inaccurate dripping position of the corrosive liquid, providing a strong guarantee for a comprehensive and in-depth evaluation of the corrosion resistance of the terminal 9.
[0094] Furthermore, this movable dripping mechanism 5 design significantly enhances the versatility and scalability of the device. It can adapt to the testing needs of terminals 9 of different sizes, shapes, and layouts without requiring large-scale modifications or adjustments to the device. By simply resetting the movement parameters and dripping scheme through the control module 3, corrosion resistance testing of various types of terminals 9 can be easily achieved, greatly improving the device's efficiency and applicability.
[0095] In summary, the addition of the Y-direction moving component 52 and the X-direction moving component 53 enables the dripping mechanism 5 to move precisely in two dimensions on a horizontal plane, providing a more flexible, accurate, and efficient solution for the extrusion testing device in the corrosion resistance testing of the terminal 9, and further improving the performance and testing level of the entire device.
[0096] Please refer to this again. Figure 3 In one embodiment of this invention, the dripping mechanism 5 is further equipped with a dripping control unit 54 on the basis of the existing Y-direction moving component 52, X-direction moving component 53 and dripping unit 51. The addition of this key component makes the function of the dripping mechanism 5 more complete and precise, and provides a more detailed and controllable means of operation for the corrosion resistance test of the terminal 9.
[0097] The dripping control unit 54 is communicatively connected to the control module 3, enabling it to receive various commands from the control module 3 in real time and precisely control the dripping frequency, dripping volume, and dripping time of the dripping unit 51 based on these commands. This precise control capability is one of the key factors in ensuring the accuracy and reliability of test results.
[0098] From the perspective of drop frequency control, the drop control unit 54 can flexibly adjust the frequency at which the drop unit 51 drips the corrosive liquid according to different testing requirements. For example, when simulating a terminal 9 being in a slightly corrosive environment for a long time, the drop control unit 54 can set a lower drop frequency, such as dripping one drop of corrosive liquid at regular intervals, to simulate the process of the corrosive liquid slowly contacting the surface of the terminal 9; while when simulating a terminal 9 being subjected to high-intensity corrosion in a short period of time, the drop control unit 54 can set the drop frequency to a higher level, such as continuously and rapidly dripping the corrosive liquid, to realistically reproduce the impact of extreme corrosive environments on the terminal 9. Through this precise control of the drop frequency, the terminal 9's tolerance to different corrosion frequencies can be more comprehensively evaluated.
[0099] Controlling the amount of etchant dripped is equally crucial. The drip control unit 54 precisely controls the volume of etchant dripped each time, ensuring that the amount of dripped solution meets the preset test requirements. In some tests with extremely stringent requirements for the amount of etchant, such as detecting the performance changes of a specific coating on the surface of terminal 9 under the action of a small amount of etchant, the drip control unit 54 can control the amount of dripped solution to the microliter level or even smaller, avoiding the impact on the accuracy of test results due to excessive or insufficient dripping. This precise dripping control capability provides strong support for in-depth research on the corrosion resistance mechanism of terminal 9.
[0100] Controlling the dripping time is also a crucial function of the dripping control unit 54. It can precisely control the start and end times of the dripping process according to the requirements of the test plan. For example, when the performance of the test terminal 9 changes after being corroded by the corrosive liquid within a specific time period, the dripping control unit 54 can start the dripping unit 51 at a preset time point and automatically stop the dripping after the set time, ensuring that the dripping process strictly adheres to the time requirements of the test plan. This precise control of the dripping time helps accurately simulate the time factor of corrosive liquid erosion experienced by the terminal 9 during actual use, providing reliable data for evaluating the long-term corrosion resistance of the terminal 9.
[0101] The implementation of the dripping control unit 54 typically relies on high-precision sensors and advanced control algorithms. The sensors monitor the dripping state of the dripping unit 51 in real time, such as dripping speed and dripping volume, and feed this data back to the dripping control unit 54. Based on the data fed back from the sensors and preset control parameters, the dripping control unit 54 uses advanced control algorithms, such as PID control algorithms, to adjust and optimize the dripping unit 51 in real time, ensuring that the dripping frequency, dripping volume, and dripping time are always kept within the preset accurate range.
[0102] In summary, the addition of the dripping control unit 54 enables the dripping mechanism 5 to possess comprehensive and high-precision control capabilities over the dripping process. Through collaborative work with the control module 3, the Y-direction movement component 52, the X-direction movement component 53, and the dripping unit 51, the dripping mechanism 5 can accurately simulate various complex corrosive environments according to different testing requirements.
[0103] Please refer to this again. Figure 1 In one embodiment of this invention, the device further includes a shielding box 6;
[0104] Both the extrusion mechanism 1 and the monitoring module 2 are located inside the shielded box 6.
[0105] It should be noted that the shielding box 6 provides direct protection for the extrusion mechanism 1 and the monitoring module 2. In addition, the shielding box 6 optimizes the overall testing environment. It creates a relatively independent and enclosed testing space, reducing interference from external factors and making the testing process more controllable and repeatable. For example, environmental parameters such as temperature and humidity can be precisely controlled within the shielding box 6 to simulate different usage conditions, further expanding the scope and depth of testing.
[0106] In summary, the shielding and protection provided by the shielding box 6 effectively reduces the impact of external interference factors on the testing process, thereby improving the accuracy and reliability of the extrusion test.
[0107] Please refer to this again. Figure 1In one embodiment of this invention, the device has been further optimized and improved based on the original structure by adding a temperature and humidity regulator 7 and a pressure valve 8. The introduction of these two components creates a more precise, stable, and controllable internal environment for the entire device, greatly improving the reliability and accuracy of the test.
[0108] The temperature and humidity regulator 7 is installed on the shielded box 6;
[0109] A temperature and humidity regulator typically consists of a temperature sensor, a humidity sensor, a heating element, a cooling element, and humidification and dehumidification devices.
[0110] During operation, temperature and humidity sensors monitor the temperature and humidity data inside the shielded enclosure 6 in real time and accurately, and quickly feed this data back to the control system of the temperature and humidity regulator 7. Upon receiving the feedback data, the control system intelligently analyzes and judges based on pre-set temperature and humidity parameters. If the detected temperature is lower than the set value, the control system will activate the heating element to raise the temperature inside the shielded enclosure 6; conversely, if the temperature is higher than the set value, it will activate the cooling element to lower the temperature to the set range. For humidity control, when the humidity is lower than the set value, the humidifier will activate, releasing an appropriate amount of water vapor into the shielded enclosure 6 to increase humidity; when the humidity is higher than the set value, the dehumidifier will start working to remove excess moisture and reduce humidity.
[0111] Through this precise adjustment mechanism, the temperature and humidity regulator 7 ensures that the interior of the shielded box 6 maintains a constant temperature and humidity. This constant temperature and humidity environment is crucial for many testing processes, especially in terminal testing where environmental conditions are extremely demanding. For example, the performance of some electronic terminals may be significantly affected by changes in temperature and humidity. Excessive temperature may lead to a decline in the performance of electronic components or even damage, while excessive humidity may cause short circuits and other malfunctions. The presence of the temperature and humidity regulator 7 provides these terminals with a stable and reliable environment, enabling the test results to truly and accurately reflect the terminal's performance under specific environmental conditions.
[0112] The air pressure valve 8 is installed on the shielding box 6;
[0113] A pneumatic valve 8 is a device specifically designed to regulate gas pressure. It typically consists of a valve body, valve core, spring, and control mechanism, and features precise pressure regulation capabilities and excellent sealing performance.
[0114] During device operation, the pressure valve 8 monitors the pressure changes inside the shielding box 6 in real time. When the pressure inside the shielding box 6 is higher than the preset value, the control mechanism of the pressure valve 8 will drive the valve core to move, opening the valve and allowing some gas to be discharged from the shielding box 6, thereby reducing the internal pressure. Conversely, when the pressure inside the shielding box 6 is lower than the preset value, the pressure valve 8 will close the valve to prevent external gas from entering. At the same time, it may work with other inflation devices to replenish gas into the shielding box 6, increasing the internal pressure until the set constant pressure state is reached.
[0115] Maintaining a constant pressure inside the shielded enclosure 6 is also crucial for the testing process. Changes in air pressure can have a significant impact on the terminal's structure and performance. For example, in certain specialized testing scenarios, such as simulating high-altitude or deep-sea environments, precisely controlling the air pressure inside the shielded enclosure 6 is a key factor in simulating real-world conditions. The presence of the pressure valve 8 allows the shielded enclosure 6 to flexibly and accurately adjust its internal air pressure according to different testing requirements, providing a stable and reliable pressure environment for terminal testing and ensuring the accuracy and reliability of the test results.
[0116] Although this invention frequently uses terms such as extrusion mechanism, monitoring module, and control module, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
[0117] Example 2
[0118] Please refer to Figure 4 This is a flowchart illustrating a compression testing method provided in Embodiment 2 of the present invention. This method is applicable to scenarios involving compression testing of terminals and is implemented using the compression testing device provided in Embodiment 1 above. The method specifically includes the following steps:
[0119] S101. The extrusion mechanism is used to extrude the terminal to be tested.
[0120] It should be noted that the extrusion mechanism has the ability to precisely control the extrusion pressure and direction to ensure that it can simulate various extrusion situations that the device may encounter during actual use. For example, for a smart ring, the extrusion mechanism can simulate scenarios such as the smart ring being accidentally squeezed between hard objects or being crushed by heavy objects.
[0121] During the extrusion process, the extrusion mechanism operates strictly according to given parameters, such as extrusion speed, extrusion pressure, and extrusion time. These parameters can be flexibly adjusted according to different test standards and end characteristics to meet diverse test requirements.
[0122] S102. The monitoring module is used to collect the initial image of the terminal before it is squeezed, and to collect the deformed image of the terminal after it is squeezed.
[0123] It should be noted that the monitoring module is an indispensable part of the extrusion test method. It is responsible for collecting image information of the terminal before and after extrusion in real time and accurately, providing basic data for subsequent deformation calculation.
[0124] When acquiring initial images of the terminal before it is compressed, the monitoring module adjusts the camera's position and angle to ensure a clear capture of the terminal's entire appearance and key components. The acquisition of these initial images is a crucial benchmark for subsequent analysis, and their quality directly impacts the accuracy of deformation calculations.
[0125] After the extrusion mechanism completes the extrusion operation on the terminal, the monitoring module immediately captures an image of the terminal's deformation after extrusion. When capturing this deformation image, it's crucial to ensure the camera's position and angle remain consistent with those used when capturing the initial image, guaranteeing comparability between the two images. The deformation image visually demonstrates the shape changes that occur after the terminal is extruded, such as dents, bulges, and cracks, providing a clear visual basis for subsequent deformation calculations.
[0126] S103. The control module calculates the deformation of the terminal based on the three-dimensional coordinates of the points of interest in the initial image and the deformed image, and generates the extrusion test results.
[0127] It should be noted that after acquiring the initial and deformed images, the control module uses image processing algorithms and three-dimensional coordinate calculation technology to accurately identify and locate points of interest in the images.
[0128] Points of interest (POIs) are points in a terminal image that have distinct features and can represent specific parts of the terminal, such as the charging indicator light on a smart ring. The control module uses image processing algorithms, such as feature extraction and edge detection algorithms, to accurately identify these POIs from the initial and deformed images and calculate their two-dimensional coordinates in their respective images.
[0129] Then, the control module uses stereo vision principles or structured light measurement technology to convert the two-dimensional coordinates of the points of interest into three-dimensional coordinates. By comparing the changes in the three-dimensional coordinates of the points of interest in the initial image and the deformed image, the control module can accurately calculate the deformation of various parts of the terminal during the extrusion process, such as displacement, angle changes, and strain. This deformation data can comprehensively and objectively reflect the deformation of the terminal under extrusion, providing a quantitative basis for evaluating the extrusion resistance of the terminal.
[0130] Finally, the control module generates detailed extrusion test results based on the calculated deformation data and preset test standards and evaluation indicators. The test results can include information such as the deformation level classification of the end product, whether it meets the extrusion resistance requirements, and potential defects and risks. Simultaneously, the control module can present the test results in intuitive charts and reports, facilitating analysis and judgment by testing personnel and providing strong support for end product design improvements, quality control, and production decisions.
[0131] In summary, the extrusion test method provided in Embodiment 2 of the present invention, through the coordinated work of the extrusion mechanism, monitoring module, and control module, achieves accurate simulation of the extrusion process of the terminal, accurate image acquisition, and accurate calculation of deformation. It can provide reliable and comprehensive test results for evaluating the extrusion resistance performance of the terminal, and has high practical value and promotion significance.
[0132] Please refer to Figure 5 In one embodiment of this invention, prior to step S101, the method further includes the following steps, aimed at more comprehensively and deeply simulating the various challenges faced by the terminal in a real, complex environment, thereby obtaining more reliable and practical test results:
[0133] S100: The corrosive liquid is dripped onto the terminal to be tested using a dripping mechanism.
[0134] It should be noted that before the formal extrusion test process begins, the control module sends a command to the dripping mechanism according to the preset test plan, activating the dripping mechanism to cause the corrosive liquid to drip onto the surface of the terminal to be tested. The dripping location can be precisely controlled according to test requirements, targeting a specific part of the terminal. The dripping time and number of drips can also be adjusted according to actual conditions to simulate different degrees of corrosion.
[0135] The purpose of this step is to subject the terminal to a corrosive environment before the extrusion test, simulating the surface coating damage and material performance degradation that may occur during long-term use due to contact with corrosive substances. After corrosion treatment, the terminal's structure and performance will change to some extent, and these changes will directly affect the results of the subsequent extrusion test, enabling the test results to more realistically reflect the terminal's extrusion resistance in actual complex environments.
[0136] In summary, this invention, based on the original extrusion test method, adds a pre-step step of dripping corrosive liquid onto the terminal under test by a dripping mechanism. This allows the entire test method to more comprehensively and realistically simulate the conditions faced by the terminal in a real complex environment, thereby obtaining more reliable and practical extrusion test results. This provides a more valuable reference for the performance evaluation and improvement of the terminal, and has high practical value and promotion significance.
