Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of chip testing, and particularly to an aging test method, device, and readable storage medium for a wireless charging device. Background Art
[0002] Wireless power technology (Wireless Power Transmission), also known as inductive charging or contactless charging, uses the principle of near-field induction to achieve energy transmission from a power supply device to a power-consuming device. Since wireless charging can achieve the charging function without wiring, its products are not restricted by sockets and cables. So far, there have also appeared various wireless high-tech products in society, providing convenience in people's lives. Most of the recently introduced smartphones have the function of wireless charging. The energy transfer is achieved through the principle of electromagnetic induction, and the principle can be analogized to an AC transformer. Figure 1 It is a schematic diagram of wireless charging.
[0003] Wireless charging is further divided into BPP (products support power below 5W, use the Qi protocol, and must pass the BPP certification) and EPP (products support power above 5W, use the Qi protocol, and must pass the EPP certification). There are wireless chargings with different powers on the market, including 5W, 7.5W, 10W, 15W, 20W, and so on.
[0004] Generally speaking, electronic devices, whether they are components, parts, or the whole machine, etc., need to be subjected to aging tests. Aging and testing are two steps, and the aging test is to age first and then test in the process. After the electronic device is used, for example, after ten-odd hours, one month, one year, or three years, various problems may be found. If these problems are not subjected to certain aging settings, they cannot be detected during the test. Therefore, in order to avoid these problems that may occur in the subsequent use of electronic products, many domestic or foreign standards stipulate that aging tests must be carried out in the detection of electronic appliances. The aging test is generally completed by the manufacturer or a first-class electronic appliance detection technology company. It discovers the problems existing in the product through the test and modifies them in time, minimizing the problems of the products reaching consumers' hands and improving the product reliability.
[0005] During the process of using a wireless charging device by a user, there will be phenomena of repeated contact and removal, which will cause an instantaneous increase in current or voltage, resulting in damage to the chip or peripheral components. Accelerating the above process of testing is the aging test. The current aging test method for wireless charging devices is to repeatedly place them manually, with low efficiency. When conducting an aging test on a batch of wireless charging products, a large amount of manpower and material resources are required, increasing the verification time and reducing the production efficiency.

[0063] The present disclosure provides an aging test method, device, and readable storage medium for a wireless charging device, so as to efficiently and quickly age wireless charging products and obtain aging test results.
[0064] To make the purpose, technical solutions, and advantages of the present disclosure clearer and more understandable, the present disclosure will be further described in detail below with reference to specific embodiments and the accompanying drawings.
[0065] Certain embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments are shown. In fact, the various embodiments of the present disclosure may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will satisfy applicable legal requirements.
[0066] In an exemplary embodiment of the present disclosure, an aging test device for a wireless charging device is provided.
[0067] Figure 2 It is a schematic structural diagram of the aging test device for the wireless charging device according to the embodiment of the present disclosure. As Figure 2 shown, the aging test device for the wireless charging device of the present disclosure includes: a control device 1, an electronic load 7, a numerical control power supply 8, and a lifting table. Among them, the lifting table includes a stepping motor controller 2, a stepping motor 3, a lead screw 4, and a base 9.
[0068] The wireless charging device under test includes a wireless transmitting device TX and a wireless receiving device RX. The wireless transmitting device TX is powered by the numerical control power supply 8 of the aging test device to generate an inductive coupling effect, thereby powering the wireless receiving device RX. The wireless receiving device RX generates an inductive coupling with the wireless transmitting device TX, thereby generating electrical energy and providing a voltage to the electronic load 7. For example, the electronic load 7 simulates charging at the mobile phone end. The wireless receiving device RX is arranged at the mobile phone end, and the wireless transmitting device TX provides mobile phone electrical energy to the wireless receiving device RX. The wireless receiving device RX of different charging schemes corresponds to the wireless transmitting device TX of different schemes.
[0069] The condition for the wireless receiving device RX and the wireless transmitting device TX to generate an inductive coupling is that the relative distance between the two is within a predetermined range. By adjusting the relative distance between the two, the wireless charging device can be switched between the working state and the non-working state. In this embodiment, the wireless receiving device RX5 of the wireless charging device under test is connected to the lead screw 4, and the wireless transmitting device TX6 of the wireless charging device under test is arranged on the base 9.
[0070] When performing the aging test, the position of the lifting table is controlled by the control device 1, so as to drive and change the relative position between the wireless receiving device RX5 and the wireless transmitting device TX6 of the wireless charging device under test. During the charging aging test process, after the lifting table descends, the wireless receiving device RX enters the working state and obtains voltage and current data; when the lifting table rises, the wireless receiving device RX and the wireless transmitting device TX are separated, and the wireless charging product does not work, realizing the simulation of the aging process of the wireless charging device.
[0071] Among them, the control device 1 is used to send commands to control the rotation of the stepper motor controller 2, and expand the electronic load 7 and the numerical control power supply 8. In this embodiment, the control device 1 controls the stepper motor controller 2 through a USB connection, and is connected to the electronic load 7 and the numerical control power supply 8 through a General-Purpose Interface Bus (GPIB), and is used to set the current value of the electronic load 7 and the voltage value of the numerical control power supply 8. In some embodiments, the control device 1 may be a computer.
[0072] The lifting platform includes a stepper motor controller 2, a stepper motor 3, a lead screw 4, a base 9, etc. By fixing the wireless receiving device RX of the wireless charging device to be measured to the movable platform of the lifting platform, the relative position between the wireless receiving device RX and the wireless transmitting device TX is controlled by the lifting of the movable platform of the lifting platform, so as to simulate the situation where the wireless receiving device RX and the wireless transmitting device TX repeatedly come into contact and separate during the operation of the wireless charging device.
[0073] In a specific embodiment, the wireless receiving device RX is connected to the movable platform, and its movement is controlled to drive the wireless receiving device RX to rise or fall; the movable platform is nested in the middle of the lead screw 4, and the movement of the movable platform is driven by the rotation of the lead screw 4; the stepper motor is arranged at the top of the lifting platform, and the upper part of the lead screw is connected to the stepper motor. The stepper motor provides power for the lead screw and drives the rotation of the lead screw; the stepper motor controller 2 is connected to the control device 1 through a USB, and controls the rotation speed, rotation time, rotation direction, etc. of the stepper motor 3; the wireless transmitting device TX is fixed to the base 9, and the fixed position is aligned with the wireless receiving device RX fixed on the lead screw 4 of the lifting platform. The control device 1 controls the stepper motor controller 2, thereby driving the stepper motor 3 and its connected lead screw, and further changing the position of the wireless receiving device RX.
[0074] The position where the wireless receiving device RX and the wireless transmitting device TX can generate inductive coupling is set as the origin position. When the lifting platform descends below the origin position, the wireless charging device enters the working state, and the wireless transmitting device TX transmits energy to the wireless receiving device RX through the coil to achieve wireless charging; after the lifting platform rises above the origin position, due to the distance limitation of wireless charging, the wireless charging system cannot obtain radiant energy, and the entire wireless charging system enters the shutdown state.
[0075] The electronic load 7 and the numerically controlled power supply 8 are respectively connected to the wireless receiving device RX and the wireless transmitting end TX of the wireless charging device. Specifically, the numerically controlled power supply 8 is used to supply power to the wireless transmitting device TX. Different wireless transmitting device TX schemes adopt different voltage values, and different voltage values can be provided through the numerically controlled power supply 8. The numerically controlled power supply 8 can be controlled by the control device 1 to adjust its output to adapt to different wireless charging schemes, so as to measure the wireless transmitting device TX and the wireless receiving device RX with different powers. The electronic load 7 is used to simulate the load of the electronic device charged wirelessly. The electronic load 7 is connected to the wireless receiving device RX. The wireless transmitting device TX charges the wireless receiving device RX, and the wireless receiving device RX drives the electronic load 7, that is, the wireless receiving device RX acts as the power supply of the electronic load and provides voltage to it.
[0076] To obtain the results of the aging test, the aging test device of the wireless charging device further includes a voltage acquisition device and a current acquisition device, which are used to acquire the voltage of the numerically controlled power supply and the current data of the electronic load when the wireless charging device is in operation.
[0077] In the second schematic embodiment of the present disclosure, an aging test method for a wireless charging device is provided.

[0081] S3, control the lowering and staying of the lifting table, detect the current of the wireless transmitting chip and the voltage value of the electronic load, and judge whether the current of the wireless transmitting chip and the voltage value of the electronic load are within the set range. If not, it means the work fails; if the test values are within the range, go to step S4;
[0082] S4, control the rising speed and rising distance of the height lifting table. This distance makes the wireless charging product not work, and control the staying time in the non-working area (the highest point);
[0083] S5. Determine whether the number of test cycles is completed. If the number of test cycles has not been reached, return to step S3; otherwise, end the test and display that the test is successful.

[0089] S32. Control the staying time of the lifting platform at the working area (the lowest point).

[0093] S2'. Set the origin of the lifting platform and select the working power of the aging test device for the wireless charging device, including 5W / 10W / 15W / 20W, etc.
[0094] S3'. Control the lifting platform to descend and stay, detect the current of the wireless transmitting chip and the voltage value of the electronic load, and determine whether the current of the wireless transmitting chip and the voltage value of the electronic load are within the set range. If they are not within this range, it indicates that the work fails; if the test values are within the range, then go to step S4'.
[0095] S4'. Control the rising speed and rising distance of the height lifting platform, and this distance makes the wireless charging product not work, and control the staying time at the non-working area (the highest point).
[0096] At S5’, determine whether the number of test cycles is completed. If the number of test cycles has not been reached, return to step S3’. Otherwise, end the test and display that the test is successful.
[0097] Specifically, the step S2’ includes:
