These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0043] Before introducing the embodiments of this application, the application background of the embodiments of this application will be explained first:
[0044] Currently, charging terminals are increasingly widely used in small smart devices (such as smart rings, smart bracelets, etc.). Testing charging terminals can ensure that they can safely and stably provide power to smart devices.
[0045] The electrical performance test of the charging terminals mainly checks their electrical characteristics to ensure that parameters such as current and voltage meet design requirements, preventing problems such as overheating or unstable charging. The mechanical performance test of the charging terminals mainly verifies their physical reliability during use, including the number of insertion / removal cycles and mechanical strength. The environmental reliability test of the charging terminals mainly tests their performance under different temperature and humidity conditions.
[0046] However, in the existing technology, the testing of charging terminals requires a lot of manual intervention, such as manually designing test methods, executing test steps, and recording test results. This testing method has shortcomings such as the single form of test data, the inability of manual testing to be synchronized with the actual operation process, and the possibility of errors in manual judgment of test results. Therefore, the manual testing process is cumbersome and the test results are not real-time, which is not conducive to the analysis and efficient resolution of abnormal problems.
[0047] Therefore, designing a device for efficient charging terminal testing has become an urgent technical problem to be solved.
[0048] To address the technical problems existing in the prior art, the inventors of this application have the following concept: the prior art requires manual design of test methods and manual execution of test steps. This application can use a clamping unit to fix the device under test, and then use the lifting unit of the charging unit as an intelligent adjustment device to automatically adjust the position of the charging base so that the conductive end of the device under test contacts the charging pin of the charging unit. The charging unit charges the device under test and automatically records the test data generated during the test in the current acquisition unit. The current acquisition unit automatically transmits the test data to the computer for analysis.
[0049] The technical solution of this application will now be described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.
[0050] Figure 1 Schematic diagram of the structure of the test equipment provided in the embodiments of this application Figure 1 ,like Figure 1 As shown, the test device may include: a current acquisition unit 11, a charging unit 12, a controller 13, and a clamping unit 15 for fixing the device under test 14;
[0051] Optionally, the charging unit 12 includes: a charging base 121, a lifting unit 123 connected to the charging base 121, and at least one first charging pin 122 is provided on the charging base 121.
[0052] In this implementation, the charging unit 12 includes a charging base 121 for providing charging current and a lifting unit 123 connected to the charging base 121 for adjusting the distance between the charging base 121 and the clamping unit 15. In addition, the charging base 121 is provided with at least one first charging pin 122 for transmitting power to the device under test 14 to ensure that the device under test 14 can be charged.
[0053] The first charging pin 122 can move back and forth and left and right on the charging base 121 to adapt to the charging pin positions of different types of devices under test 14. The number of first charging pins 122 provided on the charging base 121 is not limited and can be increased or decreased according to the actual application requirements. They may include power input pins, ground pins, data transmission pins, etc.
[0054] In one possible implementation, there are two first charging pins 122, namely a power input pin and a ground pin.
[0055] Optionally, the charging unit 12 is arranged opposite to the clamping unit 15;
[0056] In this implementation, the charging unit 12 and the clamping unit 15 are configured in a specific relative position in space, where the relative position can be arbitrary, such as up and down, left and right, etc.
[0057] The clamping unit 15 is a unit used to fix or support the device under test 14, which is used to ensure the stability and accuracy of the device under test 14 throughout the testing process, thereby improving testing efficiency.
[0058] In one possible implementation, the charging unit 12 and the clamping unit 15 are positioned vertically relative to each other.
[0059] Optionally, the controller 13 is used to control the lifting and lowering of the lifting unit 123 to adjust the first state of the charging unit 12 charging the device under test 14 held by the clamping unit 15.
[0060] In this implementation, the controller 13 is used to coordinate and control the movement of the entire device, including the lifting unit 123, to adjust the distance between the charging unit 12 and the clamping unit 15, thereby adapting to different sizes of the device under test 14, so as to achieve charging contact between the clamping unit 15 and the device under test 14.
[0061] Depending on the distance between the charging unit 12 and the clamping unit 15, the first state can be either a charging state or a non-charging state. The controller 13 can be located at any idle position in the test equipment or outside the test equipment. It can control the position of the intelligent adjustment device (e.g., the lifting unit 123) in the test equipment by sending control signals.
[0062] The lifting unit 123 is equipped with a drive motor 1231. The drive motor 1231 of the lifting unit 123 is used to adjust the longitudinal distance between the charging base 121 and the clamping unit 15, thereby realizing the up and down adjustment function of the charging base 121. It can control the first charging pin 122 and the charging pin of the device under test 14 to make accurate contact during the test charging process.
[0063] In addition, the distance between the charging base 121 and the clamping unit 15 is adjusted by the lifting unit 123 so that the charging base 121 can adapt to the test device 14 of different shapes and sizes, ensuring that no matter how the size of the test device 14 changes, the first charging pin 122 on the charging base 121 can be accurately connected to the charging pin of the test device 14.
[0064] In one possible implementation, the user sets the test requirement to 1000 test charging cycles on the computer. The computer sends the test requirement instruction to the controller 13. After receiving the test instruction, the controller 13 controls the lifting unit 123 to adjust the first charging pin 122 to contact the charging pin of the device under test 14 1000 times according to the test requirement, and uses the current acquisition unit 11 to collect the current data during the test.
[0065] It is worth noting that the computer involved in this application embodiment can also be used as controller 13 to directly control the intelligent adjustment device in the test equipment.
[0066] Optionally, the current acquisition unit 11 is connected to any of the first charging pins 122 to acquire the current data of the first charging pins 122.
[0067] In this implementation, the current acquisition unit 11 is connected to any one of the first charging pins 122 to acquire the current data of the device under test 14 during the test charging process, that is, the current data transmitted by the first charging pin 122.
[0068] The current acquisition unit 11 records the current change data in the form of a time series to monitor the charging current during the test charging process and record the current change trend, which is convenient for subsequent analysis of current fluctuations and charging stability during the charging process.
[0069] In one possible implementation, the current acquisition unit 11 can be a galvanometer.
[0070] In one possible implementation, the current acquisition unit 11 transmits the acquired data to a computer. The computer analyzes the current and voltage data acquired by the current acquisition unit 11 to assess the charging efficiency and battery health status, and to determine whether there is a risk of overcharging or battery damage.
[0071] Furthermore, the testing equipment also includes: a first rod 16, a second rod 17, and a base unit 18;
[0072] In this implementation, the first rod 16 and the second rod 17 are used to adjust the position of the clamping unit 15, thereby adjusting the position of the device under test 14. The base unit 18 is used to fix the first rod 16, the current acquisition unit 11, the charging unit 12 and other modules.
[0073] Optionally, the first rod 16 and the charging unit 12 are parallel to each other and respectively perpendicular to each other on the base unit 18;
[0074] In this implementation, the first rod 16 and the charging unit 12 are respectively vertically arranged on the base unit 18, and the first rod 16 and the charging unit 12 are arranged in parallel. The first rod 16 can control the longitudinal height position of the device under test 14 so as to facilitate the subsequent control of the conductive end (i.e. the charging pin) of the device under test 14 to contact the first charging pin 122, that is, the charging base 121 charges the device under test 14.
[0075] Optionally, the second rod 17 is arranged parallel to the upper side of the base unit 18 and connected to the middle section of the first rod 16;
[0076] In this implementation, the second rod 17 is connected to the middle section of the first rod 16 and is positioned directly above the base unit 18. It is used to adjust the lateral position of the device under test 14, so as to facilitate the control of the charging pin of the device under test 14 to contact the first charging pin 122, that is, the charging base 121 charges the device under test 14.
[0077] The height of the second rod 17 is adjustable, meaning that the second rod 17 can move up and down on the first rod 16.
[0078] Optionally, the clamping unit 15 is connected to the second rod 17.
[0079] In this implementation, the clamping unit 15 is connected to the second rod 17 to fix the device to be tested 14.
[0080] The clamping unit 15 ensures that the device under test 14 is in the correct position during testing, preventing displacement or misalignment and guaranteeing the accuracy and precision of the test results. Simultaneously, the clamping unit 15 should avoid contact with sensitive parts of the device under test 14 (such as charging pins) during use to prevent scratching, damage, or contamination of the device under test and to avoid affecting the test results.
[0081] Furthermore, the testing equipment also includes: housing unit 19;
[0082] Optionally, the housing unit 19 is a sealed unit, and the current acquisition unit 11, charging unit 12, controller 13, clamping unit 15, first rod 16, second rod 17, and base unit 18 are all located inside the housing unit.
[0083] In this implementation, the housing unit 19 serves as a hermetically sealed unit, primarily used to protect other internal units and ensure the airtightness of the equipment. The housing unit 19, through its sealed design, prevents external factors such as water, dust, and moisture from entering the equipment, thereby protecting other internal units from damage and ensuring the accuracy of the test. The housing unit 19 can also provide physical protection for internal components, preventing damage to other internal units from external impacts, vibrations, or mechanical pressure.
[0084] The housing unit 19 includes a stainless steel layer and a thermal insulation layer. The stainless steel layer is located on the outside of the housing unit 19. It possesses high hardness, strength, and corrosion resistance, effectively resisting external impacts, scratches, and collisions. Simultaneously, the stainless steel layer also exhibits electromagnetic shielding properties, reducing the influence of external electromagnetic interference on the device under test 14. The thermal insulation layer is located inside the stainless steel layer of the housing unit 19. This layer effectively isolates the housing unit from external temperature changes, maintaining a stable internal temperature. Furthermore, it helps control the internal humidity of the housing unit 19, preventing external moisture or condensation from entering and thus preventing short circuits, corrosion, or performance degradation of the circuit boards caused by excessive humidity, ensuring the accuracy of the test results from the device under test 14.
[0085] Optionally, the base unit 18 is disposed on the inner bottom of the housing unit 19.
[0086] In this implementation, the base unit 18 is located at the bottom inner side of the housing unit 19 and is used to fix the current acquisition unit 11, the charging unit 12 and other units, so as to ensure that the other units fixed on the base unit 18 inside the housing unit 19 can operate stably.
[0087] The base unit 18 serves as the bottom support for the housing unit 19, responsible for bearing and distributing the weight of various components (such as the charging unit 12) inside the housing unit 19. This ensures the structural stability of the testing equipment and prevents these components from loosening or shifting during use, thus avoiding damage or malfunction due to vibration or impact. The base unit 18 is the core of the internal layout of the housing unit 19. A well-designed base unit 18 can optimize the placement of other units, allowing for compact and efficient integration of the various modules within the housing unit 19, while avoiding mutual interference or excessive space occupation.
[0088] The testing equipment provided in this application includes: a current acquisition unit, a charging unit, a controller, and a clamping unit for fixing the device under test. The charging unit includes: a charging base and a lifting unit connected to the charging base. At least one first charging pin is provided on the charging base. The charging unit and the clamping unit are arranged opposite to each other. The controller controls the lifting of the lifting unit to adjust the charging unit to a first state where the device under test is being charged by the clamping unit. The current acquisition unit is connected to any of the first charging pins to acquire current data from the first charging pins. In this technical solution, the lifting unit of the charging unit adjusts the relative position of the device under test and the charging unit to simulate a charging scenario, and the current acquisition unit collects current data during the test, facilitating subsequent analysis of the charging performance during the test. This achieves the effect of automatically and efficiently testing the charging performance of the device under test.
[0089] Based on the above embodiments, Figure 2 Schematic diagram of the structure of the test equipment provided in the embodiments of this application Figure 2 ,like Figure 2 As shown, the testing equipment also includes: a temperature control unit 20;
[0090] Optionally, the temperature control unit 20 is disposed on the housing unit 19 and is used to control the temperature and humidity inside the housing unit 19.
[0091] In this implementation, the temperature control unit 20 is mainly used to control the temperature and humidity inside the housing unit 19 to ensure that the device under test 14 is kept in a preset temperature and humidity environment during the test, so as to obtain the charging performance data of the device under test 14 under different preset temperature and humidity environments.
[0092] The temperature control unit 20 includes a temperature sensor (used to monitor the temperature inside the housing unit 19 in real time, acquire temperature data and feed it back to the control system), a humidity sensor (used to monitor the humidity inside the housing unit 19 and also feed the humidity data back to the temperature control system), a heating or cooling device (used to raise or lower the temperature based on the data acquired by the temperature sensor), a humidifying or dehumidifying device (used for humidity control, which may include a humidifier, dehumidifier or airflow conditioning system, to adjust humidity by increasing or decreasing the moisture in the air), and a control system (used to automatically adjust the working status of the heating, cooling, humidifying or dehumidifying devices based on sensor data to maintain the temperature and humidity within the set range).
[0093] In one possible implementation, the user sets the test environment requirements on the computer as a temperature of 20°C and a relative humidity of 50%. The computer sends a command to the controller 13. Upon receiving the test environment command set by the computer, the controller 13 controls the temperature control unit 20 to adjust the test environment temperature inside the housing unit 19 to 20°C and 50% relative humidity.
[0094] The temperature control unit 20 can be located at any position on any side of the housing unit 19 except the bottom surface. This application embodiment does not limit the position of the temperature control unit 20.
[0095] In one possible implementation, the temperature control unit 20 is located on the upper left of the front of the housing unit 19.
[0096] Furthermore, the testing equipment also includes: a pressure control unit 21;
[0097] Optionally, the pressure control unit 21 is disposed on the housing unit 19 and is used to control the atmospheric pressure inside the housing unit 19.
[0098] In this implementation, the pressure control unit 21 is installed on the housing unit 19 to adjust the atmospheric pressure inside the housing unit 19, ensure the stability of the internal environment of the housing unit 19, protect the device from the influence of external air pressure changes, thereby ensuring that the device under test 14 is tested under different set atmospheric pressures and obtaining charging performance data of the device under test 14 under different atmospheric pressures.
[0099] The pressure control unit 21 typically uses an air pump or air valve to adjust the air flow inside the housing unit 19, thereby adjusting the air pressure. It uses a pressure sensor to detect the internal air pressure of the housing unit 19 and feeds the detection result back to the control system to achieve precise adjustment. The control system adjusts the air pump or air valve according to the preset target air pressure to maintain a stable internal pressure.
[0100] The pressure control unit 21 can be located at any position on the upper side, left side, or right side of the housing unit 19. This embodiment does not limit the position of the pressure control unit 21.
[0101] In one possible implementation, the pressure control unit 21 is located at the upper middle position of the housing unit 19.
[0102] In one possible implementation, the user sets the test requirement on the computer to an atmospheric pressure of 1 kPa. The computer sends the test requirement command to the controller 13. The controller 13 receives the test requirement command and controls the pressure control unit 21 to adjust the internal air pressure of the housing unit 19 to 1 kPa.
[0103] Furthermore, Figure 3 Schematic diagram of the structure of the test equipment provided in the embodiments of this application Figure 3 ,like Figure 3 As shown, the test equipment also includes: resistor unit 22;
[0104] Optionally, the resistor unit 22 is disposed on the base unit 18;
[0105] In this implementation, the resistor unit 22 is disposed on the base unit 18 and is used to limit the charging current of the device under test 14 and control the charging voltage.
[0106] Among them, the resistor unit 22 can be a power resistor (capable of withstanding large current and power, usually used to adjust or limit the current), a precision resistor (with higher precision, widely used in occasions requiring precise voltage or current adjustment), etc.
[0107] In one possible implementation, resistor element 22 is a precision resistor.
[0108] Optionally, the two ends of the resistor unit 22 are respectively connected to the two conductive ends of the device under test 14 fixed by the clamping unit 15.
[0109] In this implementation, the two ends of the resistor unit 22 are respectively connected to the two conductive ends of the device under test 14 to simulate the load of the device under test 14 when it is working, to ensure that the device under test 14 works under preset current conditions, so as to obtain the charging performance data of the device under test 14 under different preset current conditions.
[0110] In one possible implementation, the user sets the required resistance for the test to 1 ohm on the computer. The computer sends the test requirement instruction to the controller 13, which receives the test requirement instruction and controls the resistor unit 22 to adjust the resistance to 1 ohm.
[0111] In this embodiment, the computer can also be used as a controller to directly control the resistor unit 22.
[0112] The testing equipment provided in this application embodiment also includes a temperature control unit, a voltage control unit, and a resistance unit. In this technical solution, the temperature control unit and the voltage control unit adjust the temperature, humidity, and atmospheric pressure inside the housing, achieving intelligent adjustment of temperature, humidity, and atmospheric pressure according to testing requirements, thus reducing testing errors caused by temperature and humidity changes. The resistance unit works in conjunction with the temperature control unit and the voltage control unit to test the charging performance of the device under test under different current conditions within specific temperature, humidity, or pressure conditions, providing a more comprehensive testing method.
[0113] Based on the above embodiments, Figure 4 Schematic diagram of the structure of the test equipment provided in the embodiments of this application Figure 4 ,like Figure 4 As shown, the testing equipment also includes: a third rod 23 and a camera unit 24;
[0114] Optionally, the third rod 23 is vertically connected to the upper region of the first rod 16;
[0115] In this implementation, the third rod 23 is vertically connected to the upper region of the first rod 16, which ensures that the relative positions of the third rod 23 and the first rod 16 are fixed, making it easy to precisely control the up and down movement of the third rod 23.
[0116] The third rod 23 is a rod that can be used for lifting and lowering, located above the second rod 17.
[0117] Optionally, the camera unit 24 is mounted on the third rod 23 for monitoring all units inside the housing unit 19.
[0118] In this implementation, the camera unit 24 is mounted on the third rod 23 and is used to monitor other units inside the test equipment during the test process, providing real-time images of the internal environment of the test equipment or each working unit, and to perform safety monitoring of the test equipment to ensure that there are no safety hazards inside the test equipment.
[0119] Among them, the camera unit 24 is an infrared camera. The infrared camera can capture images in a completely dark environment by illuminating and receiving infrared radiation. Therefore, it is very suitable for monitoring at night or in places with insufficient light. Since the test equipment provided in this application embodiment is a sealed device, an infrared camera is selected as the camera unit 24.
[0120] Furthermore, the testing equipment also includes: a first motor 25;
[0121] Optionally, the first motor 25 is located at the first rod 16 and is used to adjust the height of the second rod 17 and the height of the third rod 23.
[0122] In this implementation, the first motor 25 is located at any position inside the first rod 16 to adjust the height of the second rod 17 and the third rod 23 so that the device under test 14 fixed by the clamping unit 15 on the second rod 17 and the camera unit 24 connected to the third rod 23 are in a suitable longitudinal position.
[0123] The first motor 25, also known as the drive motor, can be an AC drive motor. AC drive motors are stable, low-cost, and suitable for scenarios requiring continuous and smooth lifting. Alternatively, a DC drive motor can be used. DC motors are commonly used in lifting devices requiring more precise speed and position adjustments, enabling more accurate control.

[0129] Furthermore, the testing equipment also includes: a third motor 27;
[0130] Optionally, a third motor 27 is located at the third rod 23 and is used to adjust the position of the camera unit 24.
[0131] In this implementation, the third motor 27 is set at any position inside the third rod 23 to adjust the lateral position of the camera unit 24 so that the camera unit 24 can acquire video and image information of the entire process of the conductive end of the device under test 14 and the first charging pin 122 of the charging base 121 contacting each other (i.e., the entire charging and discharging test process).
[0132] In one possible implementation, the third motor 27 is a DC drive motor.
[0133] Prior to this implementation, the user sets the test requirements on the computer as follows: the camera unit 24 is located in the center of the third rod 23, and the clamping unit 15 is located directly above the charging base 121. The computer sends the test requirement command to the controller 13, and the controller 13 controls the first motor 25, the second motor 26, and the third motor 27 to adjust the positions of the clamping unit 15 on the second rod 17 and the camera unit 24 on the third rod 23, respectively.
[0134] The testing equipment provided in this application embodiment further includes: a third rod, a camera unit, a first motor, a second motor, and a third motor. In this technical solution, the third rod supports the camera unit, enabling the acquisition of video of the entire testing process from a suitable position within the sealed testing equipment according to testing requirements. This facilitates the identification of faults during the testing process. The first, second, and third motors are used to adjust the positions of the second and third rods, respectively, achieving the technical effect of intelligently adjusting the camera unit and clamping unit connected to the second and third rods according to testing requirements.
[0135] Based on the above embodiments, Figure 5 This is a schematic diagram of the workflow of the testing equipment provided in the embodiments of this application, such as... Figure 5 The following is a detailed description of the workflow of the testing equipment:
[0136] Step 1, Begin.
[0137] In this step, the user sets the product characteristics of the device under test (such as the appearance and dimensions of the device under test), the test conditions (such as 1000 charging contact tests) and the test steps on the computer, and the computer sends the test-related instructions set above to the device under test.
[0138] Step 2, Positioning and Calibration.
[0139] In this step, the testing equipment performs positioning calibration on units such as camera unit 24, device under test 14, and charging base 121 to eliminate positional errors caused by the previous test.
[0140] Step 3: Initialize and calibrate the clamping unit.
[0141] In this step, the clamping unit 15 is initialized and calibrated to eliminate the positional error of the clamping unit 15 caused by the previous test.
[0142] Step 4: Horizontal operation.
[0143] In this step, the testing equipment intelligently adjusts the camera unit 24, the device under test 14, and the charging base 121 to appropriate positions according to the test-related instructions set above by the computer.
[0144] Step 5: Charge and discharge test.
[0145] In this step, the test equipment receives test instructions from the computer (e.g., 1000 charging contact tests) and begins preparations to perform the charge-discharge test.
[0146] Step 6: Vertical operation.
[0147] In this step, the testing equipment uses the first motor 25 to adjust the second rod 17 to move up and down so that the conductive end of the device under test 14 makes contact with and disconnects from the first charging pin 122. This is repeated 1000 times to complete the above-mentioned 1000 charging contact tests. At the same time, the current acquisition unit 11 collects the current data during the 1000 charging contact tests.
[0148] Step 7: Limit sample comparison.
[0149] In this step, the ammeter uploads the current data collected in real time during 1000 charging contact tests to the computer. The computer processes the current data and performs limit sample comparison to analyze whether the current data falls within the normal fluctuation range.
[0150] Limit sample comparison refers to verifying whether certain samples meet a specific standard or limit by comparing their performance or characteristics.
[0151] In this embodiment of the application, the performance of the device under test will be affected after the number of charge and discharge cycles exceeds a certain range (e.g., 800 times). Therefore, the limit sample comparison in this embodiment of the application refers to comparing the collected test current data with the existing current error range to analyze whether the test current data is within the current error range.
