[0034] A performance evaluation module according to an embodiment of the present application, including a carrier unit, a power source, a measurement unit, and a processing unit, etc., can be used for performance evaluation of VCM, Driver IC, and Gyro. Exemplary embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0035] Figure 1 is a schematic functional module diagram of a performance evaluation apparatus 100 according to an embodiment of the present application. As shown in Figure 1 According to the embodiment, the performance evaluation apparatus 100 can include a carrier unit 10, a power source 20, a measurement unit 30, and a processing unit 40 in terms of function.

[0036] The carrier unit 10 includes at least one carrier for carrying at least one device under test. For example, the carrier unit 10 can include one or more VCM carriers for carrying one or more VCMs, and accordingly, the device under test includes a VCM.

[0037] In some embodiments, the carrier unit 10 can include a plurality of carriers for carrying a plurality of devices under test. For example, as shown in Figure 2 the carrier unit 10 can include a VCM carrier, a Driver IC carrier, and a Gyro carrier, and accordingly, the device under test includes a VCM, a Driver IC, and a Gyro.

[0038] The power source 20 is electrically connected to the carrier unit 10, and is configured to provide constant current or constant voltage to at least one device under test carried by the carrier unit 10. The power source 20 can include, for example, a constant current source module, and can provide driving current to the device under test, such as a VCM or a Gyro. The power source 20 can also include, for example, a constant voltage source module, and can provide driving voltage to the device under test, such as a Driver IC or a Gyro.

[0039] The measurement unit 30 acquires data of a performance to be measured generated by the device under test according to the constant current or constant voltage provided by the power source 20. The measurement unit 30 can include, for example, a digital multimeter (DMM), a laser displacement sensor, a controllable vibration table, an oscilloscope, a voltage acquisition module, etc., and can measure information such as displacement, current, or voltage generated by the device under test, or other parameters indicative of the performance of the device under test, which will be described in further detail below.

[0040] The processing unit 40 is electrically connected to the carrier unit 10, the power source 20 and the measuring unit 30, respectively, for generating the performance evaluation result of the device under test according to the data acquired by the measuring unit 30 and the performance parameters of the device under test. For example, the processing unit 40 can control the power source 20 to selectively provide constant current or constant voltage to the device under test, so as to selectively obtain the test results as described below.

[0041] Specifically, when the device under test is a VCM, the power source 20 can include a constant current source for providing constant current to the VCM. Under the control of the processing unit 40, the current provided by the constant current source can be determined according to the power size of the VCM, for example, the processing unit 40 can also control the combination of the constant current source module and the variable resistor to provide step current to the VCM, so as to obtain the data (parameters) representing the performance of the VCM through the measurement of the measuring unit. As an example, the drive current value of the VCM can be in the range of, for example, -120mA-120mA. Alternatively, as a practical application option, the power source 20 can include a constant voltage source for providing constant voltage to the VCM, and the drive voltage value can be in the range of, for example, 1.5V-6V. Specifically, the performance data (parameters) of the VCM can include at least one of stroke, starting current, sensitivity, linearity and magnetic performance. The processing unit 40 then generates the performance evaluation result of the device under test according to the data (parameters) acquired by the measuring unit 30.

[0042] Specifically, when the device under test is a Driver IC, the power source 20 can include a constant voltage source for providing constant voltage to the Driver IC. The voltage provided by the constant voltage source can be determined according to the rated voltage range of the Driver IC, for example, the drive voltage value of the Driver IC can be in the range of, for example, 1.5V-6V. Alternatively, as a practical application option, the power source 20 can include a constant current source for providing constant current to the Driver IC, and the drive current value can be in the range of, for example, -120mA-120mA. Specifically, the performance parameters of the Driver IC can include at least one of linearity of output current, power supply voltage test, erasable times, aging test and electrostatic voltage resistance test. The processing unit 40 can control the measuring unit 30 to measure the Driver IC to obtain the parameters representing these performances, so as to further generate the performance evaluation result of the device under test.

[0043] Specifically, when the device under test is a gyro, the power source 20 may include a constant current source for providing a constant current to the gyro or a constant voltage source for providing a constant voltage to the gyro. For example, the constant current source may provide a driving current to the gyro in the range of -120 mA to 120 mA, and the constant voltage source may provide a driving voltage to the gyro in the range of 1.5 V to 6 V. Specifically, the performance parameters of the gyro may include at least one of: axis control performance, acceleration accuracy, sensitivity, zero point correction, temperature drift, and self-test performance. The processing unit 40 may control the measurement unit 30 to measure the gyro to obtain parameters representing these performance characteristics, thereby further generating performance evaluation results for the device under test.

[0044] In addition, when the device under test is a Gyro, the processing unit 40 can also control the controllable vibration table included in the measuring unit 30 (see Figure 2 Processing unit 40 controls the controllable vibration table to output vibrations of varying frequencies, amplitudes, and directions to simulate the gyroscope's test environment, allowing measurement unit 30 to obtain gyroscope performance parameters under these test conditions. Specifically, gyroscope performance parameters may include at least one of axis control performance, acceleration accuracy, sensitivity, zero-point correction, temperature drift, and self-test performance. Based on the data characterizing these performance characteristics obtained by measurement unit 30, processing unit 40 generates gyroscope performance evaluation results.

[0054] In Figure 2 ​Although the specific implementation shown shows that the modules 40, 60 and the power supply module are arranged on the IC circuit board, and some other components are arranged outside the IC circuit board, those skilled in the art should understand that this arrangement is only exemplary, and those skilled in the art can adjust which components are arranged on the IC circuit board and which components are arranged outside the IC circuit board according to needs.

[0055] For the VCM carried by the VCM carrier 10-1, the constant current source module 20-1 provides a constant current to the VCM through the VCM carrier 10-1. The VCM generates displacement information according to the constant current supplied. The laser displacement sensor 30-2 determines the displacement data of the VCM according to the displacement information generated by the VCM.

Alternatively, as a practical application option, the laser displacement sensor 30-2 can also convert the acquired displacement information generated by the VCM into a corresponding voltage signal through the oscilloscope 30-4, and then collect and feed back to the processing unit 40 by the voltage acquisition module 30-5. The processing unit 40 analyzes and generates the stroke performance evaluation result of the VCM. Moreover, the processing unit 40 generates other performance evaluation results of the VCM including at least one of the starting current, the sensitivity, the linearity, and the magnetic hysteresis performance by analyzing other performance parameters of the VCM acquired by the measurement unit 30.
