Fig. 1 shows a schematic top view of a system 100 for testing a wireless charging module according to an embodiment of the invention. It should be appreciated that system 100 may also include additional elements not shown, the scope of the invention being not limited in this respect.
As shown in fig. 1, the system 100 may include a control unit 110, a robotic arm 120, a module testing area 130, a load placement area 140, and a signal acquisition unit 150.
Regarding the module test area 130, it may be configured to place a wireless charging module to be tested. According to an embodiment of the present invention, the system 100 may further include a module power supply unit (not shown) electrically connected with the module test area 130 or integrated with the module test area 130 and configured to supply power to the wireless charging module placed at the module test area 130.

With respect to a load, it may refer to a load to be charged that may be used to test a wireless charging module. According to an embodiment of the invention, the load comprises any load suitable for wireless charging, such as a cell phone, a watch, a headset, etc.
Regarding the signal acquisition unit 150, it may be configured to acquire real-time signal data of the wireless charging module by wired or wireless means. For example, the signal acquisition unit 150 may be connected to the wireless charging module through a serial port tool, so as to collect real-time signal data when the wireless charging module works in a wired manner; alternatively, the signal acquisition unit 150 may wirelessly acquire real-time signal data (e.g., communication data messages in space, etc.) of the wireless charging module while it is operating, for example, by a receiver such as sniffer. According to an embodiment of the present invention, the signal acquisition unit 150 may acquire real-time signal data of the wireless charging module by wired or wireless means, for example, for each predetermined position where the load moves above the wireless charging module.
With respect to the control unit 110, it may be used to perform the steps of the method for testing the wireless charging module. Specifically, according to an embodiment of the present invention, the control unit 110 may be configured to control the robotic arm 120 to grasp the load at the load placement area 140 in order to move the load over the wireless charging module such that the center of the load is aligned with the center of the wireless charging module; and controlling the mechanical arm 120 to drive the load to move above the wireless charging module, and collecting real-time signal data of the wireless charging module, so as to determine the performance of the wireless charging module based on the real-time signal data.

In still other embodiments, the control unit 110 may include a display unit 115 as shown in fig. 1, which may be configured to visually present the charging efficiency of the wireless charging module. Specifically, according to an embodiment of the present invention, the control unit 110 may be configured to receive data information acquired by the signal acquisition unit 150 of the system 100, to determine the charging efficiency of the wireless charging module based at least on real-time signal data acquired of the wireless charging module, the position data of the load relative to the wireless charging module, and to present the determined charging efficiency of the wireless charging module in a visual manner in the display unit 115.

For example, the robotic arm 120 may be configured to grasp the load at the load placement region 140, move the load three-dimensionally over the wireless charging module, and the like based on instructions of the control unit 110.
A method for testing a wireless charging module according to an embodiment of the present invention will be described in detail below with reference to fig. 2. Fig. 2 shows a flow chart of a method 200 for testing a wireless charging module according to an embodiment of the invention. The method 200 may be performed by the system 100 as shown in fig. 1. It should be appreciated that method 200 may also include additional actions not shown and/or may omit actions shown, the scope of the invention being not limited in this respect.
In step 202, a wireless charging module to be tested is placed in a module test area.
According to an embodiment of the present invention, a wireless charging module to be tested may be placed in the module test area 130 of the system 100 as shown in fig. 1. For example, a wireless charging module to be tested may be placed on a designated carrier of the module test area 130.
In step 204, a load to be charged is placed in the load placement area.
According to an embodiment of the present invention, a load to be charged may be placed in the load placement area 140 of the system 100 as shown in fig. 1. For example, a load to be charged may be placed at a specified position of the load placement area 140. According to some embodiments of the present invention, the load placement area 140 may be marked with coordinates such as zero points to indicate the placement location of the load to be charged. For example, a specific angle of the load to be charged may be placed at the zero point coordinates in order for the robot arm to more accurately identify and grasp the load at the load placement area.
At step 206, the control unit controls the robotic arm to grasp the load at the load placement area in order to move the load over the wireless charging module such that the center of the load is aligned with the center of the wireless charging module.
According to an embodiment of the present invention, the robotic arm 120 may be controlled at the control unit 110 as shown in fig. 1 to grasp the load at the load placement area 140 in order to move the load over the wireless charging module such that the center of the load is aligned with the center of the wireless charging module. In some embodiments of the present invention, the robotic arm 120 may be controlled to grasp the load based on the center position of the load in order to more precisely align the center of the load with the center of the wireless charging module. Specifically, in the present invention, regarding the control of the robot arm 120 to grasp the load at the load placement area 140, it may further include: determining profile data of the load, and determining a center of the load based on the profile data of the load; and controlling the robot arm 120 to grasp the load based on the center of the load.
Regarding the profile data of the load, it is possible to obtain specific profile data of the load by, for example, directly inputting the load model by the user or measuring the load by means such as scanning, image recognition, or the like. For example, a correspondence table including a plurality of load models and corresponding profile data may be configured at the control unit 110. When the user inputs the load model, the control unit 110 may determine profile data of the current load based on the configured correspondence table; alternatively, the control unit 110 may measure the length of the load in each dimension, for example, the length of the load in the x-axis and the y-axis, in a scanning manner, such as for a load of which model determination is difficult or a non-standard size, thereby obtaining profile data of the current load.
According to an embodiment of the present invention, in response to determining profile data of a load, a center of the load may then be determined based on the determined profile data. For example, the center coordinates of the load may be calculated based on the length in each dimension of the load, such as the length in the x-axis and y-axis.
Regarding the control of the robotic arm 120 to grasp the load based on the center of the load, it may further include: controlling the mechanical arm 120 to move to the upper side of the load, so that the sucker of the mechanical arm 120 is positioned right above the center of the load; and controlling the robot arm 120 to suck the load via the suction cup, wherein the suction cup is sucked at a position of the upper surface of the load corresponding to the center of the load.
By determining the center of the load based on the profile data of the load and controlling the robot arm 120 to adsorb the load at a position on the upper surface of the load corresponding to the center of the load via the suction cup, the robot arm 120 can accurately grasp the center of the load, so that when the load is moved above the wireless charging module, the center of the load can be aligned with the center of the wireless charging module more accurately, and thus the path of movement of the subsequent load above the wireless charging module can be determined and controlled more accurately.
In step 208, the control unit controls the mechanical arm to drive the load to move above the wireless charging module, and collects real-time signal data of the wireless charging module, so as to determine performance of the wireless charging module based on the real-time signal data.
According to an embodiment of the present invention, at the control unit 110 shown in fig. 1, the control arm 120 drives the load to move in a horizontal direction and/or a vertical direction in a three-dimensional space above the wireless charging module, including: lateral movement in the x-axis direction, longitudinal movement in the y-axis direction, and vertical movement in the z-axis direction. In an embodiment of the present invention, the mechanical arm 120 may be controlled to drive the load to move in a three-dimensional space such as 150mm by 200mm by 100mm above the wireless charging module.
In some embodiments, according to the test requirement, a plurality of matrix blocks can be divided for the wireless charging module, so that the mechanical arm 120 can drive the load to move above the wireless charging module based on the divided matrix blocks, so as to collect real-time signal data at different positions of the wireless charging module. Specifically, regarding the control of the mechanical arm 120 to drive the load to move above the wireless charging module, the method may further include: dividing a plurality of matrix blocks for the wireless charging module to control the mechanical arm 120 to drive the load to traverse the corresponding position above each matrix block; for each matrix block, the control arm 120 adjusts the relative position of the load and matrix block.
As regards the matrix blocks, any suitable size matrix blocks may be used, for example, 1mm x 1mm or 2mm x 2mm matrix blocks, without limitation.
With respect to the relative position of the load and matrix blocks, it may include: the area of overlap of the load with the matrix block in the vertical direction, the height of the load relative to the matrix block, etc. According to the embodiment of the invention, for each matrix block, the mechanical arm 120 can be controlled to adjust the overlapping area of the load and the current matrix block in the vertical direction, the height of the load relative to the current matrix block and the like, so as to obtain real-time signal data of the wireless charging module for the load at different positions, thereby more comprehensively and truly simulating the working condition of the wireless charging module after the actual installation. In still other embodiments, for each matrix block, the mechanical arm 120 may be controlled to drive the load to move above the matrix block, so that the center of the load is aligned with the center of the matrix block, and then the relative position of the load and the matrix block is adjusted according to the test requirement.
According to an embodiment of the present invention, the control unit 110 may control the mechanical arm 120 to drive the load to traverse all the divided matrix blocks. Specifically, the mechanical arm 120 may be controlled to drive the load to move based on a preset path, where the path passes through all matrix blocks. For example, a path of the load movement may be set at the control unit 110 by inputting parameters including a moving step distance, an interval time, a charging height, etc., so that the robot arm 120 can move the load based on the set path based on an instruction of the control unit 110.
The moving step distance refers to the distance that the mechanical arm drives the load to move each time. According to an embodiment of the invention, the stride of movement may be related to the size of the matrix block. For example, for a 1mm by 1mm matrix block, the movement stride may be set to 1mm to enable the load to move through all matrix blocks.
By interval time, it is meant the residence time of the load above each matrix block.
With respect to the charging height, it refers to the height of the load in a vertical direction from the surface of the wireless charging module.
The real-time signal data of the wireless charging module refers to performance parameters, such as power, voltage, frequency, etc., for reflecting stable communication and power transmission between the wireless charging module and the load under the working state. Specifically, according to an embodiment of the present invention, the real-time signal data of the wireless charging module may include: one or more of output power, input voltage, input current, output voltage, output current, operating frequency, and Q value. The Q value reflects the power transmission efficiency between the wireless charging module and the load in the working state, namely the ratio of the actual transmission power between the wireless charging module and the load to the output power of the wireless charging module.
Regarding the acquisition of real-time signal data of the wireless charging module, it may be that the signal acquisition unit 150 as shown in fig. 1 acquires the real-time signal data of the wireless charging module through a wired or wireless manner. In some embodiments, the data signals generated as a result of the wireless charging module charging the load may be read in real-time by connecting, for example, a serial tool to the wireless charging module wired, e.g., by accessing the serial tool to a log (log) pin and a ground pin of the wireless charging module. In still other embodiments, a wireless receiver (such as sniffer) may be provided to receive a data signal such as a communication data message generated in space as a result of the wireless charging module charging the load, and then parameters related to power, voltage, frequency, etc. may be demodulated from the received data signal. The real working performance of the wireless charging module when charging is carried out on the load can be determined by collecting real-time signal data of the wireless charging module, so that the real working condition of the wireless charging module after being actually installed can be accurately simulated based on the collected real-time signal.
Regarding determining the performance of the wireless charging module based on the real-time signal data, it may include determining a charging efficiency of the wireless charging module based at least on a location of the load relative to the wireless charging module and the collected real-time signal data of the wireless charging module.
According to an embodiment of the present invention, each matrix block of the wireless charging module may be corresponding to real-time signal data acquired for the load when above the matrix block based on the position of the load relative to the wireless charging module and the acquired real-time signal data of the wireless charging module, such that each matrix block of the wireless charging module corresponds to corresponding signal data, so that charging efficiency at each matrix block of the wireless charging module can be visualized based on the signal data to be presented at a display unit 115 such as shown in fig. 1. For example, the charging power may be represented by a color. In one embodiment, the control unit 110 receives the real-time signal data collected by the signal collection unit 150 and demodulates the output power (RP power), the operating frequency (Freq), the input voltage (V IN ) And input current (I) IN ). The control unit 110 may then calculate the charging power η of each matrix block based on the following equation (1).
η＝RP Power/(V IN *I IN ) (1)
Further, based on the calculated charging efficiency η of each matrix block, the charging power η of different degrees is represented by, for example, different colors or different shades of the same color for all matrix blocks of the wireless charging module on the display unit 115, so that the charging performance of each matrix block of the tested wireless charging module can be displayed by the display unit 115 so as to determine the optimal charging area of the wireless charging module. In some embodiments, based on the visualized wireless charging module presented at the display unit 115, it may be quickly determined, e.g., by color, whether the currently tested wireless charging module meets the test criteria.
According to an embodiment of the present invention, parameters related to error detection may also be input at the control unit 110 to enable retesting when real-time signal data of the wireless charging module is not acquired for a period of time. For example, a threshold time, a threshold condition, or the like for error detection may be input at the control unit 110.
With respect to the threshold condition, it may be that the real-time signal data collected is less than a predetermined value, or that no real-time signal data is collected.
Thus, according to an embodiment of the present invention, controlling the robotic arm 112 to move the load over the wireless charging module may further comprise: controlling the mechanical arm 112 to drive the load to stay at the current test position for a threshold time so as to acquire real-time signal data of the wireless charging module; determining whether the acquired current signal data meets a threshold condition; and in response to determining that the collected current signal data does not meet the threshold condition, controlling the mechanical arm 112 to drive the load to move away from the current test position, and then moving the load back to the current test position again so as to collect the real-time signal data of the wireless charging module again. For example, in one example, a threshold time of 10 seconds, a threshold condition of input power RP power of 0.5W or input current I may be input at the control unit 110 IN And is more than or equal to 100mA. The robotic arm 120 may then move the load over the wireless charging module based on instructions of the control unit 110 including the entered threshold time and threshold condition. For each test position, the mechanical arm 120 may drive the load to stay at the current test position for a threshold time to collect real-time signals of the wireless charging moduleAnd judging whether the acquired current signal data meets a threshold condition or not. If the collected current signal data does not meet the threshold condition, the mechanical arm 112 may drive the load to move back to the current test position after the load is far away from the current test position, so as to re-collect the real-time signal data of the wireless charging module. For example, in one example, if the output power (RP power), the operating frequency (Freq), the input voltage (V) are demodulated based on the received real-time signal data acquired by the signal acquisition unit 150 IN ) And input current (I) IN ) And the ratio of the two is 0, the fact that no real-time signal data is acquired for the current test position is indicated, and therefore it can be determined that the current signal data acquired for the current test position does not meet the threshold condition. In this case, the mechanical arm 112 may be controlled to drive the load to move away from and return to the current test position again, so as to re-collect the real-time signal data of the wireless charging module. If the collected current signal data meets the threshold condition, the mechanical arm 112 drives the load to the next test position.
According to the embodiment of the invention, in the example that the collected current signal data does not meet the threshold condition, the power input condition of the wireless charging module can be further detected, namely, whether the wireless charging module is in a normal working state is judged, so as to determine whether retesting is needed. For example, the input voltage and input current of the wireless charging module may be further demodulated from the collected real-time signal data to determine whether the wireless charging module is in a normal operating state. In an embodiment, if the input voltage demodulated from the collected real-time signal data is 9-16V and the input current is greater than 200mA, which indicates that the wireless charging module is in a normal working state, the control unit 110 determines that the real-time signal data is abnormally collected, and retests are required for the current test position. If the input voltage demodulated from the collected real-time signal data is not within the range of 9-16V or the input current is less than 200mA, which indicates that the wireless charging module is in an abnormal working state, the control unit 110 determines that the wireless charging module is abnormal, and may report errors, for example, by lighting a red light.
According to further embodiments of the present invention, to make the measured data more accurate, multiple sets of real-time signal data for the wireless charging module may be collected for each test location to which the load is moved, and based on the collected multiple sets of data, such as averaging, to determine the performance of the wireless charging module when the load is at that location. For example, an average value of three sets of signal data may be calculated based on the closest three sets of signal data among the sets of real-time signal data acquired during the test, so as to determine the charging efficiency based on the average value.
