[0055] Example 1:

[0056] Figure 1 This is a structural diagram of the magnetic testing device for smart wearable devices according to an embodiment of the present application. Figure 2 This is a schematic diagram of the top view of the rotating test fixture in the magnetic testing device for smart wearable devices described in an embodiment of the present application.

[0057] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a magnetic testing device for smart wearable devices, including a testing shell 10 and a testing mechanism 20 built into the testing shell 10 , wherein the testing mechanism 20 includes: a rotating testing fixture 21 and a driving source.

[0058] like Figure 2 As shown, in an embodiment of the present application, a rotating test fixture 21 is used to install a component to be tested 101 for a magnetic test. The rotating test fixture 21 includes a turntable 211 and a first clamp 212 and a second clamp 213 installed on the turntable 211 and used to clamp the component to be tested 101. A scale is provided on the turntable 211.

[0059] It should be noted that each of the first and second clamps 212, 213 is provided with several adjustment holes 102. Fasteners 103 are inserted through the adjustment holes 102 into the turntable 211 to secure the first and second clamps 212, 213 to the turntable 211. The adjustment holes 102 can also be used to adjust the tightness with which the first and second clamps 212, 213 clamp the component under test 101. In this embodiment, the fasteners 103 can be screws, bolts, or the like. The first clamp 212 restrains the component under test 101 from above both horizontally and vertically, while the second clamp 213 restrains the component under test 101 from below vertically. The component under test 101 can be the middle frame of a smartwatch. Adjustment members 214 for position control are provided at both ends of the first clamp 212. The adjustment members 214 can be screws, bolts, or the like.

[0060] like Figure 1 As shown, in an embodiment of the present application, the driving source is in transmission connection with the turntable 211 , and the driving source is used to drive the turntable 211 to rotate so as to perform a magnetic test on the component to be tested 101 .

[0061] It should be noted that the driving source can be a motor. In this embodiment, the driving source drives the turntable 211 to rotate and drives the component to be tested 101 to rotate a certain angle, thereby performing a magnetic test on the component to be tested 101 at the angle.

[0062] The present application provides a magnetic testing device for a smart wearable device, comprising a test housing and a test mechanism built into the test housing. The test mechanism comprises a rotating test fixture for mounting a component to be tested for magnetic testing. The rotating test fixture comprises a turntable and a first clamp and a second clamp mounted on the turntable and used to clamp the component to be tested. The turntable is provided with a scale. A drive source is connected to the turntable in a transmission manner and is used to drive the turntable to rotate to perform a magnetic test on the component to be tested. The magnetic testing device for a smart wearable device automatically tests the magnetic force of the component to be tested through the drive source and the rotating test fixture, thereby achieving high testing efficiency. The magnetic testing device for a smart wearable device has a simple structure and low testing cost. The device solves the technical problem that magnetic testing of existing smart wearable devices relies on manual operation, resulting in high cost and low testing efficiency.

[0063] like Figure 1 As shown, in one embodiment of the present application, the testing mechanism 20 includes: a limit assembly located above the turntable 211, the limit assembly includes a pressure rod driver, a pressure rod 8, a weight 6, a weight fixing column 4 and a base 3, bases 3 are respectively provided on both sides of the turntable 211, and weight fixing columns 4 are provided on the bases 3. The weight 6 is fixed on the side of the weight fixing column 4 close to the turntable 211, the pressure rod 8 is provided above the turntable 211, and the pressure rod driver (not marked in the figure) is connected to the pressure rod 8.

[0064] It should be noted that the base 3 is arranged on both sides of the turntable 211, and a weight fixing column 4 is provided on the base 3. The weight fixing column 4 is provided with an adjustable clamp (not marked in the figure) for fixing the weight 6 on the side close to the turntable 211, so that weights of different weights can be fixed by the adjustable clamp; when the component to be measured 101 is placed on the turntable 211, the weight 6 is just located above both sides of the component to be measured 101 and can apply a certain pressure to the component to be measured; the pressure rod 8 is located above the turntable 211, and the pressure rod driving member is connected to the pressure rod 8. When the component to be measured 101 is placed on the turntable 211, the pressure rod driving member can drive the pressure rod 8 to move relative to the component to be measured 101 and apply a certain pressure to the component to be measured 101, thereby achieving the purpose of limiting the component to be measured 101 on the turntable 211 through the set limit assembly.

[0065] In the embodiment of the present application, the base 3 is mounted on a slide (not marked in the figure), and the base 3 is moved by moving the slide, thereby adjusting the base 3 to be closer to or farther away from the turntable 211.

[0066] It should be noted that the weight fixing column 4 is also provided with a driving mechanism (not shown in the figure) for driving the clamp used to fix the weight 6 to move up and down, so that before the component to be measured 101 is installed, the weight 6 is first driven to rise to facilitate the placement of the component to be measured 101, and after the component to be measured 101 is placed, the weight 6 is driven to fall to apply pressure to the component to be measured 101.

[0067] like Figure 1 As shown, in one embodiment of the present application, a pressure valve 1 for adjusting the air pressure in the test housing 10 and a temperature and humidity controller 2 for adjusting the temperature and humidity in the test housing 10 are installed on the test housing 10 .

[0068] It should be noted that this smart wearable magnetic testing device adjusts the air pressure within the test housing 10 via an air pressure valve 1, ensuring that the air pressure within the test housing 10 satisfies the magnetic testing requirements of the component under test 101, thereby improving test accuracy. This smart wearable magnetic testing device also adjusts the temperature and humidity within the test housing 10 via a temperature and humidity controller 2, ensuring that the temperature and humidity within the test housing 10 meet the magnetic testing requirements of the component under test 101, thereby improving test accuracy. In this embodiment, the temperature and humidity controller primarily consists of three components: a sensor, a controller, and a heater (or fan, etc.). The operating principle of the temperature and humidity controller is that the sensor detects temperature and humidity information within the chamber and transmits it to the controller for analysis and processing. When the temperature and humidity within the chamber reach or exceed preset values, the relay contacts in the controller close, and the heater (or fan) is powered on and begins operating, heating or blowing air into the chamber. After a period of time, if the temperature or humidity within the chamber deviates from the set values, the relay contacts in the controller open, and heating or blowing ceases. In addition to basic functions, different models also include auxiliary functions such as disconnection alarm output, transmitter output, communication, and forced heating and blowing.

[0069] Example 2:

[0070] Figure 3 This is a flowchart of the steps of the magnetic testing method for smart wearable devices described in an embodiment of the present application.

[0071] like Figure 3 As shown, the embodiment of the present application provides a magnetic testing method for a smart wearable device, which includes the following steps:

[0072] S1. Acquire test data, where the test data includes the number of test laps and N test angles for each test lap.

[0073] It should be noted that the test data is obtained in step S1. In this embodiment, the number of test circles is recorded as P, and P can be selected as 200 circles. The N test angles of each test circle can be 5 degrees, 10 degrees, 15 degrees,..., N×5 degrees respectively. If one circle is 360 degrees, then N is 120.

[0074] S2. Perform a magnetic test on the component to be tested using the magnetic testing device of the smart wearable according to the test data to obtain magnetic test data.

[0075] It should be noted that the content of the magnetic testing device of the smart wearable has been described in Example 1 and will not be repeated in this embodiment. In step S2, the magnetic testing device of the smart wearable is used to perform a magnetic test on the component to be tested according to each test angle to obtain N magnetic test values, completing one circle of magnetic testing on the component to be tested; then, the step of performing one circle of magnetic testing on the component to be tested is repeated according to the number of test circles, obtaining magnetic test data consisting of P×N magnetic test values, which provides data for subsequent analysis to obtain the magnetic values ​​at each test angle.

[0076] S3. Process the magnetic test data to obtain the magnetic value of each test angle.

[0077] It should be noted that, in step S3, the magnetic test data obtained in step S2 is analyzed to obtain magnetic values ​​at various test angles, providing judgment data for subsequent judgment of whether the component to be tested is a qualified product.

[0078] S4. Determine whether the magnetic force of the component to be tested is qualified based on all the magnetic force values.

[0079] It should be noted that in step S4, the magnetic force of the component under test is determined to be qualified by checking whether the magnetic force values ​​at each test angle obtained in step S3 are all within a set threshold range. In this embodiment, if all magnetic force values ​​are within the set threshold range, the magnetic force of the component under test is determined to be qualified; if any magnetic force value is no longer within the set threshold range, the magnetic force of the component under test is determined to be unqualified. The threshold range can be set according to the requirements of the component under test and is not limited to a specific value.

[0080] The present application provides a magnetic testing method for smart wearable devices, comprising obtaining test data, the test data including the number of test turns and N test angles for each test turn; performing a magnetic test on a component to be tested using the magnetic testing device of the smart wearable device according to the test data to obtain magnetic test data; processing the magnetic test data to obtain magnetic values ​​at each test angle; and judging whether the magnetic force of the component to be tested is qualified based on all magnetic values. The magnetic testing method for smart wearable devices obtains magnetic test data for magnetic testing using a magnetic testing device of the smart wearable device, and then analyzes the magnetic test data to obtain magnetic values ​​at each test angle and judges whether the magnetic force of the component to be tested is qualified based on the magnetic test data, thereby improving the accuracy and efficiency of magnetic testing of smart wearable devices and solving the technical problems of manual operation, high cost and low testing efficiency in existing magnetic testing of smart wearable devices.

[0081] like Figure 3 As shown, in one embodiment of the present application, the magnetic test device of the smart wearable device is used to perform a magnetic test on the component to be tested according to the test data, and the magnetic test data obtained includes:

[0082] S21. The magnetic test device of the smart wearable device is set to rotate the turntable according to each test angle, and then the magnetic test device of the smart wearable device is used to perform a magnetic test on the component to be tested according to the speed, and N magnetic test values ​​corresponding to N test angles are obtained to complete a circle of magnetic testing of the component to be tested;

[0083] S22. Perform a magnetic test on the component to be tested according to step S21 according to the number of test laps to obtain N magnetic test values ​​for each test lap;

[0084] If the number of test turns is P, the magnetic test data includes P×N magnetic test values.

[0085] It should be noted that in the process of obtaining magnetic test data in step S21, the rotation speed of the turntable in the magnetic testing device of the smart wearable is first set according to the test angle, and then the turntable is controlled by the speed to rotate the component under test to the test angle to obtain the magnetic test value at that test angle. N magnetic test values ​​of the component under test are obtained at N test angles, completing one round of magnetic testing of the component under test. In step S22, the test is performed according to step S21 based on the number of test rounds to obtain magnetic test data consisting of P×N magnetic test values.

[0086] Figure 4 This is a schematic diagram of the three-axis coordinate system in the magnetic testing method for smart wearable devices described in an embodiment of the present application.

[0087] like Figure 4 As shown, in one embodiment of the present application, the magnetic test data is processed to obtain the magnetic value of each test angle, including:

[0088] A three-axis coordinate system is established in the component to be tested. Each magnetic test value includes the X-axis magnetic force, the Y-axis magnetic force, and the Z-axis magnetic force.

[0089] Obtain P magnetic test values ​​corresponding to each test angle from the magnetic test data, and obtain the orthogonal error sensitivity, X-axis sensitivity error value, Y-axis sensitivity error value, and Z-axis sensitivity error value of the magnetic sensor in the component to be tested;

[0090] Calculate the magnetic force calculation value corresponding to each magnetic test value based on the orthogonal error sensitivity, the X-axis sensitivity error value, the Y-axis sensitivity error value, the Z-axis sensitivity error value, and each magnetic test value;

[0091] The magnetic value of each test angle is obtained by calculating the P magnetic calculation values ​​corresponding to the P magnetic test values ​​in each test angle.

[0092] It should be noted that, since a magnetic sensor for testing magnetic force is provided inside the component to be tested, a three-axis coordinate system is established in the component to be tested, for example, the center of the component to be tested is used as the origin of the three-axis coordinate system, such as Figure 4 As shown, the magnetic test values ​​detected by the magnetic sensor include X-axis magnetic force, Y-axis magnetic force, and Z-axis magnetic force. The orthogonal error sensitivity, X-axis sensitivity error value, Y-axis sensitivity error value, and Z-axis sensitivity error value of the magnetic sensor in the component to be tested are obtained. Then, based on the obtained magnetic sensor data and the magnetic test value obtained in step S2, a magnetic force calculation value corresponding to the magnetic test value is calculated. Then, an average is calculated based on the P magnetic force calculation values ​​corresponding to the P magnetic test values ​​in each test angle to obtain the magnetic force average value for each test angle, and the magnetic force average value is used as the magnetic force value for the test angle.

[0093] In an embodiment of the present application, the magnetic testing device of the smart wearable device includes a magnetic test calculation formula based on the orthogonal error sensitivity, X-axis sensitivity error value, Y-axis sensitivity error value, and Z-axis sensitivity error value and each magnetic test value to obtain a magnetic calculation value corresponding to each magnetic test value; the magnetic test calculation formula is:

[0094]

[0095]

[0096]

[0097] Where M x is the X-axis magnetic force of the magnetic test value, M y is the Y-axis magnetic force of the magnetic test value, M z is the Z-axis magnetic force of the magnetic test value, K x is the X-axis sensitivity error value, K y is the Y-axis sensitivity error value, K z is the Z-axis sensitivity error value, D is the magnetic zero position error value, M c is the magnetic test measurement value, K is the orthogonal error sensitivity, M is the magnetic calculation value, and θ is the test angle.

[0098] In an embodiment of the present application, a PC-based host computer issues instructions corresponding to the magnetic testing method for the smart wearable device. After the smart wearable device responds to the instructions from the PC host computer, it sets signals step by step. The smart wearable device is connected to the PC host computer, and the PC host computer issues instructions (such as control signals and commands) to control the device, allowing it to automatically perform tests. The instructions from the host computer are fed back to the drive source, which responds and executes the operation, while also performing the corresponding pressure test. For example, the host computer issues a command to rotate at 5° / s. The drive source responds to the command, driving the turntable, which in turn rotates the component under test, thereby measuring test data. The PC host computer reads and analyzes the measured magnetic test data, ultimately making a judgment based on the set threshold range and the analyzed magnetic values ​​at each test angle.

[0099] In an embodiment of the present application, the magnetic testing method for smart wearables tests the component to be tested (such as the middle frame component of a smart meter) through the magnetic testing device of the smart wearables, and applies the rotational force required for the test to the middle frame during the process. The test results obtained are real-time, and can improve the efficiency and quality of the test and reduce the test cost.
