[0132] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application are described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application.

In addition, in the description of the embodiments of the present application, “multiple” means two or more than two.

[0134] It should be understood that the terms “first”, “second” and the like in the specification and claims of the present application and the drawings are used to distinguish different objects, and are not used to describe a particular order. In addition, the terms “include” and “have” and any variations thereof are intended to cover non-exclusive inclusion.

[0137] Charging compatibility refers to the protocol matching, hardware adaptation, and safety cooperation capability between different charging devices (such as chargers, power banks) and electronic devices (such as mobile phones, tablets) during charging, to ensure that electric energy is efficiently, stably, and safely transmitted from the charging device to the battery of the electronic device. The core is to solve the charging differences between different brands and models of devices, and to avoid charging failure, slow speed, or safety hazards caused by non-uniform technical standards.

[0138] The charging compatibility includes charging protocol compatibility, voltage compatibility, and actual charging efficiency test.

[0139] The charging protocol compatibility refers to whether the fast charging protocols supported by the electronic device and the charging device are compatible. The test content is to detect whether the electronic device supports and correctly triggers the fast charging protocol (such as PD, QC, SCP, VOOC, PPS, etc.), and whether it can automatically downgrade to a general protocol (such as 5V / 2A) when the fast charging protocols supported by the electronic device and the charging device do not match. When the fast charging protocols supported by the electronic device and the charging device successfully handshake, it is determined that the electronic device supports and correctly triggers the fast charging protocol.

[0140] The voltage compatibility refers to detecting whether the charging device can provide the voltage range supported by the electronic device (such as 5V, 9V, 12V, 20V, etc.). When the charging device can provide the voltage range supported by the electronic device, and the voltage fluctuation range of the target voltage range provided by the charging device meets the requirements, for example, the actual output voltage of the nominal 9V fluctuates within the range of ±5% of 9V, it is determined that the voltage range has compatibility.

[0141] The actual charging efficiency test includes charging speed verification and charging while using compatibility. The charging speed verification test records the charging time of the mobile phone from 0% to 100%, compares the difference between the nominal power and the actual power, and monitors the power change at different power stages (such as low-power fast charging and trickle charging after 80%). The charging while using compatibility is used to test whether the charging power is stable, whether there is a flow or overheat protection when the mobile phone is running under high load (such as gaming).

[0142] It should be understood that charging compatibility can also include other aspects of compatibility, such as compatibility of brand proprietary protocol authorization, compatibility of security protection mechanism, compatibility of interface and wire matching, and compatibility of wireless charging standards.

[0143] The current charging compatibility test process is as follows:

[0144] 1. Select the required list of samples to be tested, such as X project charger (power bank) with N mobile phones (tablets), or X project mobile phone (tablet) with N chargers (power bank).

[0145] 2. Manually create a test report template and manually configure test parameters, including but not limited to target charging power, charging icon type, target charging voltage, target charging current size, and other information.

[0146] 3. Manually build the test environment, such as manually preparing a charging extension, one or more power banks (chargers), one or more mobile phones (tablets), data lines, and third-party test tools (monitoring voltage and current) and computers (monitoring test data), and connecting them.

[0147] 4. Start the test, and manually switch to different test cases to cover different use cases during the test. This process requires manual execution. Test cases refer to simulations of actual use scenarios.

[0148] 5. Test data needs to be manually recorded, and the charging compatibility needs to be manually judged according to the test data, and the test report needs to be manually output.

[0149] As can be seen, in the prior art, manual plugging and unplugging of data lines, manual recording of test data, and manual judgment of charging compatibility are required in the charging compatibility test process, which has low test efficiency, long test period, low automation degree, and is prone to misjudgment and omission. In addition, the test report is created manually, and the test report format may not be consistent, and the normalization degree is low.

[0150] Please refer to Table 1 below, which shows the man-hour duration of each test case in the charging compatibility test in the prior art.

[0151] Table 1

[0152]

[0153] It can be seen that in the prior art, the wired charger and the charging compatibility test of more than 30 mobile phones need manual participation for as long as 93 hours.

[0154] The present application improves the above-mentioned problems, and proposes a charging compatibility test device and a charging compatibility test method, which can realize automatic test. The working process of the charging compatibility test device is as follows:

[0155] 1. The test content is determined by the staff, such as Y project charging device matching N electronic devices, or Y project electronic device matching N charging devices.

[0156] 2. One or more electronic devices and one or more charging devices related to the Y project are respectively clamped by the corresponding clamps and placed in the corresponding storage bin and scanned.

[0157] 3. The charging compatibility test device automatically creates a test report template and configures test parameters, including but not limited to target charging power, charging icon type, target charging voltage, target charging current, etc.

[0158] 4. The charging compatibility test device starts to execute the test, and automatically switches different test cases to cover different use scenarios during the test. For example, the test process needs to perform charging compatibility tests under different power, on-off state, fast insertion and slow insertion scenarios and obtain test data, for example, execute the related test cases as shown in Table 2. The test cases can be, but are not limited to, starting, ≤5% low power fast charging identification test, 95% power fast charging identification test, ≥99% power fast charging identification test, full charging process test, mobile phone slow insertion test, mobile phone fast insertion test, etc.

[0159] 5. The charging compatibility test device automatically judges the results according to the test data and outputs the test report.

[0160] Table 2

[0161]

[0162] As can be seen from Table 2, the charging compatibility test device and the charging compatibility test method in the present application can automatically switch between different test cases, which can save labor costs, and the test period can be reduced from 11 days to 2-3 days, and the time required for manual participation can be shortened to about 7 hours. Moreover, the test parameter configuration, test data recording, test result judgment and test report output are all automatically completed.

[0204] It can be understood that the second connecting plate 8221c is provided with two first position sensors 8221c3 corresponding to the active stroke position of the first clamping jaw 8223. Two first position sensors 8221c3 respectively sense the opening position and the clamping position of the first clamping jaw 8223 to determine whether the two first clamping jaws 8223 are in the opening state or the clamping state.

[0205] In some embodiments, the two first clamping jaws 8223 are both L-shaped, and the L-shaped openings of the two first clamping jaws 8223 are oppositely arranged.

Therefore, the key mechanism 8224 can include a first key mechanism 8224a and a second key mechanism 8224b. The first key mechanism 8224a is arranged on the first connecting plate 8221a and corresponds to the power key on the bottom of the electronic device 1. The second key mechanism 8224b is arranged on the second connecting plate 8221c and corresponds to the power key on the side of the electronic device 1.

For example, when the power key of the electronic device 1 is on the right side, the second key mechanism 8224b needs to be started to press the power key of the electronic device 1. When the power key of the electronic device 1 is pressed on the bottom side, the first key mechanism 8224a needs to be driven to press the power key of the electronic device 1. Wherein, the bottom of the electronic device 1 refers to the bottom when the electronic device 1 is in a portrait screen use state, and the right side of the electronic device 1 refers to the right side when the electronic device 1 is in a portrait screen use state.

The third support 913 and the fourth support 914 are in a layer plate structure and are arranged in a spaced manner. The third support 913 and the fourth support 914 are located at opposite sides of the second storage rack 911. The number of layer plates of the third support 913 and the fourth support 914 is equal to the number of the second storage racks 911. Therefore, each second storage rack 911 is arranged on one layer plate of the third support 913 and one layer plate of the fourth support 914. The second storage rack 91 further comprises a second linear drive guide mechanism 915 corresponding to each layer of the second storage rack 911 and arranged on the corresponding layer plate. The second linear drive guide mechanism 915 is connected to the second storage rack 911. The second linear drive guide mechanism 915 drives the second storage rack 911 to slide between the third position and the fourth position of the corresponding layer.

[0238] In some embodiments, the second linear drive guide mechanism 915 can be, but is not limited to, a combination of a motor and a screw drive mechanism, a combination of a motor and a belt pulley drive mechanism, a cylinder slider mechanism, a combination of a motor and a gear drive mechanism, a combination of a motor and a chain drive mechanism, a cylinder slider mechanism combined with a guide slide rail, etc. In the present embodiment, the second linear drive guide mechanism 915 is a combination of a cylinder slider mechanism and a guide slide rail.

[0246] Therefore, in the present application, the transplanting mechanism adopts the gantry type three-axis transplanting mechanism, which has a wider motion range and higher precision.

[0247] In some embodiments, the storage bin includes at least two layers of storage racks. The at least two layers of storage racks are stacked in the height direction. Each layer of storage rack is provided with at least two storage positions.

[0253] It should be noted that the charging compatibility test equipment 1000 not only needs to test the compatibility between different electronic devices 1 and different charging devices 2, but also needs to be compatible with the outer dimensions of different electronic devices 1 and different charging devices 2, in order to realize automation. Therefore, the compatibility of the outer dimensions of the electronic device 1 and the charging device 2 is also very important.

[0254] It should be noted that the above content is a general description, therefore, please refer to the specific description in the context and the relevant drawing introduction for the content in the above general description.

[0255] In some embodiments, please refer to FIG. 18 , FIG. 18This is an assembly diagram of the first clamp 18 and the electronic device 1 in the first embodiment of this application. In this embodiment, the electronic device 1 is a tablet. The charging compatibility testing equipment 1000 includes a first clamp 18 for holding the electronic device 1. The electronic device 1, with the first clamp 18 assembled, is placed in the first compartment 812 or the first test position 10 of the first storage bin 81, and is held by the first robotic arm 822 of the first transfer device 82 and transferred between the first storage bin 81 and the first test position 10.

[0256] Therefore, in this application, by setting the first clamp 18, electronic devices 1 with different external dimensions can be compatible, so that electronic devices 1 with different external dimensions can be placed in the first compartment 812 and the first test position 10 with the same size and are gripped and transferred by the same first robot arm 822.

[0257] In some embodiments, please refer to FIG. 19 , FIG. 19 for FIG. 18 An exploded view. The first clamp 18 includes a first loading portion 1810 and a first engaging portion 189. The first loading portion 1810 forms a first loading space for loading the electronic device 1. The size of the first loading space is variable. The first engaging portion 189 is located outside the loading portion and is provided with a first engaging member. The first robotic arm 822 includes a first gripper 8223 and is provided with a second engaging member. When the first engaging member engages with the second engaging member, the first transfer device 82 can transfer the first clamp 18. The first engaging member can be a first engaging hole 180 provided on the first engaging portion 189, and the second engaging member can be a first engaging protrusion 8223a on the first robotic arm 822.

[0258] In some embodiments, the first snap-fit ​​portion 189 is an inverted U-shaped structure, and the first snap-fit ​​member is a first snap-fit ​​hole 180 provided on the inverted U-shaped structure.

[0259] In some embodiments, the first clamp 18 comprises a first base 181, a first positioning block 182, a second positioning block 183, a third positioning block 184 and a fourth positioning block 185, a first bidirectional screw rod transmission mechanism 186 and a first unidirectional screw rod transmission mechanism 187, the first positioning block 182, the second positioning block 183, the third positioning block 184 and the fourth positioning block 185 are respectively located on four edges of the first base 181, the first positioning block 182 and the second positioning block 183 are oppositely arranged, the third positioning block 184 and the fourth positioning block 185 are oppositely arranged, the first bidirectional screw rod transmission mechanism 186 is arranged on the first base 181, and the first positioning block 182 and the second positioning block 183 are connected to opposite sides of the first bidirectional screw rod transmission mechanism 186, the first bidirectional screw rod transmission mechanism 186 is used to drive the first positioning block 182 and the second positioning block 183 to move synchronously towards each other or away from each other in a first direction (Y-axis direction), the third positioning block 184 is arranged on the first unidirectional screw rod transmission mechanism 187, the first unidirectional screw rod transmission mechanism 187 can drive the third positioning block 184 to move towards or away from the side of the fourth positioning block 185 in a second direction (X-axis direction), the first direction and the second direction are arranged perpendicularly, and the first positioning block 182, the second positioning block 183, the third positioning block 184 and the fourth positioning block 185 cooperate to form a receiving space which is suitable for the size of the electronic device 1 and centrally clamps the electronic device 1. Among them, the first direction is parallel to the Y-axis direction, and the second direction is parallel to the X-axis direction.

[0260] Therefore, since the first bidirectional screw rod transmission mechanism 186 is a bidirectional clamping positioning mechanism, it can drive the first positioning block 182 and the second positioning block 183 to move synchronously towards each other or away from each other in the first direction, the first bidirectional screw rod transmission mechanism 186 can centrally clamp the electronic device 1 in the first direction, so that the electronic device 1 can be centrally installed on the first clamp 18, and the first unidirectional screw rod transmission mechanism 187 can drive the third positioning block 184 to move towards the side of the fourth positioning block 185 in the second direction. Therefore, the first unidirectional screw rod transmission mechanism 187 can position the electronic device 1 to the side of the fourth positioning block 185 in the second direction, and the fourth positioning block 185 is located on the side of the first clamp 18 close to the first plug-in mechanism 3, which can facilitate the alignment and plug-in operation of the first plug-in mechanism 3.

[0261] In some embodiments, the first bidirectional screw rod transmission mechanism 186 comprises a third screw rod 1861 and two third screw rod nuts 1862. The third screw rod 1861 is divided into two segments along its length direction (Y-axis direction), one of which is provided with left-hand threads, and the other of which is provided with right-hand threads. The two third screw rod nuts 1862 are respectively threadedly connected to the left-hand threads and the right-hand threads and are symmetrically arranged relative to the center point of the first clamp 18. It can be understood that the center point refers to the desired centering position of the first clamp 18 when clamping the electronic device 1. When the electronic device 1 is located at the centering position, it will be convenient for subsequent plugging and unplugging of the first plug-pull mechanism 3. The third screw rod 1861 extends along the first direction (Y-axis direction), and the first positioning block 182 can be slidably connected to one of the third screw rod nuts 1862, and the second positioning block 183 can be slidably connected to the other third screw rod nut 1862, so as to give support and limit to the electronic device 1 on the opposite sides of the electronic device 1 in the first direction. When the third screw rod 1861 rotates, it drives the two third screw rod nuts 1862 to move towards each other or away from each other, which also synchronously drives the first positioning block 182 and the second positioning block 183 to move towards each other or away from each other, thereby achieving the centering clamping of the electronic device 1 in the first direction.

[0262] In some embodiments, the first bidirectional screw rod transmission mechanism 186 further comprises a first knob 1863 fixedly connected to one end of the third screw rod 1861, and the third screw rod 1861 can be driven to rotate through the first knob 1863. It can be understood that in other embodiments, the first knob 1863 can be replaced by a motor, which is not limited here.

[0263] In some embodiments, the first bidirectional screw rod transmission mechanism 186 further comprises two first moving blocks 1864 fixedly connected to the two third screw rod nuts 1862, respectively. Therefore, when the third screw rod 1861 rotates and drives the two third screw rod nuts 1862 to move towards each other or away from each other in the first direction, it also synchronously drives the two first moving blocks 1864 to move towards each other or away from each other in the first direction. It should be noted that the length direction of the first moving block 1864 extends along the second direction (X-axis direction), and the top surface of the first moving block 1864 is track-shaped. The first positioning block 182 can be one or more and can be slidably connected to the top surface of one of the first moving blocks 1864 and can slide along the second direction under the guidance of the first moving block 1864. The second positioning block 183 can be one or more and can be slidably connected to the top surface of the other first moving block 1864 and can slide along the second direction under the guidance of the other first moving block 1864.

[0264] Thus, the first positioning block 182 can slide on the top surface of one of the first moving blocks 1864 along the second direction, and the second positioning block 183 can slide on the top surface of the other of the first moving blocks 1864 along the second direction, so that the positions of the first positioning block 182 and the second positioning block 183 along the second direction can be adjusted as needed to clamp different positions of the electronic device 1 placed on the first clamp 18.

[0265] In some embodiments, the first bidirectional screw driving mechanism 186 can further include one or more first guiding assemblies 1865, which are arranged on the first base 181 in parallel with the third screw rod 1861 and are connected to the two first moving blocks 1864 to guide the movement of the two first moving blocks 1864 along the first direction. It can be understood that at least one first guiding assembly 1865 can be one or more first guiding assemblies 1865. The first guiding assembly 1865 can guide and support the movement of the two first moving blocks 1864 along the first direction, so that the movement of the first moving blocks 1864 is smoother and more reliable. It can be understood that the first guiding assembly 1865 can be, but is not limited to, a structure of a sliding rail and a sliding block.

[0266] In some embodiments, the first unidirectional screw driving mechanism 187 includes a fourth screw rod 1871 and a fourth screw nut 1872, the fourth screw rod 1871 extends along the second direction, i.e., the aforementioned X-axis direction, and the fourth screw nut 1872 is connected to the fourth screw rod 1871, and the third positioning block 184 is slidably connected to the fourth screw nut 1872. When the fourth screw rod 1871 rotates, the fourth screw nut 1872 can be driven to move linearly along the second direction, and in turn, the third positioning block 184 can be driven to move linearly along the second direction, so as to clamp or release the electronic device 1 placed on the first clamp 18, thereby achieving clamping of the electronic device 1 placed on the first clamp 18.

[0267] In some embodiments, the first unidirectional screw driving mechanism 187 further includes a second moving block 1873, which is fixedly connected to the fourth screw nut 1872, and the length direction of the second moving block 1873 extends along the first direction (Y-axis direction), and the top surface of the second moving block 1873 is in the shape of a track, and the third positioning block 184 is slidably connected to the top surface of the second moving block 1873 and can slide along the first direction under the guidance of the second moving block 1873.

[0268] Thus, the third positioning block 184 can slide along the first direction and can be arranged at different positions on the side of the electronic device 1 placed on the first clamp 18 along the second direction as needed.

[0269] In some embodiments, the first one-way screw driving mechanism 187 further comprises a second knob 1874 fixedly connected to one end of the fourth screw rod 1871, and the fourth screw rod 1871 can be driven to rotate through the second knob 1874. It can be understood that in other embodiments, the second knob 1874 can be replaced by a motor, which is not limited here.

[0270] In some embodiments, the first one-way screw driving mechanism 187 can further comprise one or more second guide assemblies 1875, which are arranged in parallel with the fourth screw rod 1871 on the first base 181 and above the first guide assembly 1865, and are connected to the second moving block 1873 and guide the movement of the second moving block 1873 in the second direction. It can be understood that at least one second guide assembly 1875 can be one or more second guide assemblies 1875. The second guide assembly 1875 can guide and support the movement of the second moving block 1873 in the second direction, so that the movement of the second moving block 1873 is more smooth and reliable. It can be understood that the second guide assembly 1875 can be, but is not limited to, a structure of a sliding rail and a sliding block.

[0271] In some embodiments, the first clamp 18 further comprises a first fixed block 188, which also extends along the first direction (Y-axis direction), and the top surface of the first fixed block 188 is in the shape of a track, and the fourth positioning block 185 can be slidably connected to the top surface of the first fixed block 188 and can slide along the first direction under the guidance of the first fixed block 188.

[0272] Therefore, the fourth positioning block 185 can slide along the first direction and can be arranged at different positions on the side of the electronic device 1 placed on the first clamp 18 in the second direction as needed.

[0273] In some embodiments, the first positioning block 182, the second positioning block 183, the third positioning block 184 and the fourth positioning block 185 all comprise a first positioning part L1, and the shape of the first positioning part L1 of the first positioning block 182, the second positioning block 183, the third positioning block 184 and the fourth positioning block 185 is L-shaped, and the included angle between the two surfaces forming the first positioning part L1 is acute, which can reduce the contact area of the first positioning part L1 and the electronic device 1 and improve the positioning accuracy.

[0274] In some embodiments, the first clamp 18 comprises two first clamping portions 189, which are respectively arranged on opposite sides of the first base 181. In the present embodiment, the first clamping portion 189 is in the shape of an inverted U. Each first clamping portion 189 is provided with a first clamping hole 180, which can be clamped with the first clamping protrusion 8223a on the first clamping jaw 8223. It can be understood that in other embodiments, the positions of the first clamping protrusion 8223a and the first clamping hole 180 can be interchanged, i.e., the first clamping protrusion 8223a can be arranged on the first clamping portion 189, and the first clamping hole 180 can be arranged on the first clamping jaw 8223. Alternatively, the first clamping jaw 8223 is provided with the first clamping hole 180 and the first clamping protrusion 8223a, and the first clamping portion 189 is correspondingly provided with another first clamping protrusion 8223a and another first clamping hole 180. This is not limited herein.

[0275] Please refer to FIG. 20 and FIG. 21 , FIG. 20 FIG. 1 is an assembly view of the first test position 10, the first clamp 18 and the pressing mechanism 102 in an embodiment of the present application, FIG. 21 is FIG. 20 an exploded view. The first test position 10 is in the shape of a plate structure and is arranged on the rack 17. The upper surface of the first test position 10 is provided with a first positioning pin 101. The corresponding position of the first base 181 of the first clamp 18 is provided with a first positioning hole 1811. When the first positioning pin 101 is inserted into the first positioning hole 1811, the first clamp 18 can be accurately fixed to the first test position 10. Among them, the positioning between the first clamp 18 and the first test position 10 through the first positioning pin 101 and the first positioning hole 1811 is one of the aforementioned reference points 15.

[0276] Therefore, the accurate positioning between the first clamp 18 and the first test position 10 provides convenience for the visual alignment and plugging work between the first plugging mechanism 3 and the electronic equipment 1.

[0277] In some embodiments, the charging compatibility test equipment 1000 further comprises an air cooling device 16 arranged for the first test position 10, which is arranged below the first test position 10. FIG. 21 As can be seen from FIG. 1, the air cooling device 16 arranged for the first test position 10 is located below the first test position 10, and the support plate of the first test position 10 is provided with a hole corresponding to the position of the air cooling device 16. Therefore, the air cooling device 16 can air cool and dissipate heat for the electronic equipment 1 located on the first test position 10 from below.

[0278] In some embodiments, please refer to FIG. 22 , FIG. 22 isFIG. 21 The charging compatibility test equipment 1000 further comprises a pressing mechanism 102, which is arranged adjacent to the first test position 10, and presses the first clamp 18 when the first clamp 18 is placed on the first test position 10 by the first transplanting mechanism 821, so that the first positioning pin 101 is completely inserted into the first positioning hole 1811 on the first clamp 18. Moreover, when the first positioning pin 101 is inserted into the first positioning hole 1811 on the first clamp 18, the force of the first plug-pull mechanism 3 when performing the plug-pull work on the electronic device 1 located on the first clamp 18 will not push the first clamp 18 to move.

[0279] As shown in FIG. 22 , the pressing mechanism 102 is a crank linkage mechanism, which comprises a first connecting rod 1021, a second connecting rod 1022 and a third connecting rod 1023. The first connecting rod 1021 is the output shaft of the air cylinder, the second connecting rod 1022 is rotatably connected between the first connecting rod 1021 and one end of the third connecting rod 1023, and the other end of the third connecting rod 1023 is rotatably connected to the outside of the air cylinder. The second connecting rod 1022 is provided with a pressing head 1022a at the end extending relative to the third connecting rod 1023. When the first connecting rod 1021 extends relative to the air cylinder, the end of the second connecting rod 1022 with the pressing head 1022a is lowered and presses the first clamp 18. Conversely, when the first connecting rod 1021 retracts relative to the air cylinder, the end of the second connecting rod 1022 with the pressing head 1022a is raised and away from the first clamp 18.

[0280] Therefore, the charging compatibility test equipment 1000 of the present application further comprises the pressing mechanism 102, which can ensure that the first positioning hole 1811 on the first clamp 18 is aligned with and completely inserted with the first positioning pin 101 on the first test position 10, thereby providing support for subsequent work.

[0281] It should be noted that in the present embodiment, the charging compatibility test equipment 1000 comprises two pressing mechanisms 102, which are respectively located on opposite sides of the first test position 10. Therefore, the two pressing mechanisms 102 can simultaneously press the first clamp 18 from opposite sides of the first clamp 18, so that the first clamp 18 can be flatly attached to the upper surface of the first test position 10, thereby avoiding the problem of uneven stress leading to interference.

[0282] Please refer to FIG. 23 and FIG. 24 , FIG. 23 , which are the partial exploded view of the first test position 10, the first clamp 18 and the pressing mechanism 102 in the second embodiment of the present application, FIG. 24 which are the partial exploded view of the first test position 10, the first clamp 18 and the pressing mechanism 102 in the second embodiment of the present application,FIG. 23 The exploded view of the first clamp 18 and the electronic device 1. The first clamp 18 in the second embodiment is similar to the first clamp 18 in the first embodiment, and the difference is that the first clamp 18 in the second embodiment is applied to a mobile phone, so in the second embodiment, the electronic device 1 is a mobile phone. Moreover, the first clamp 18 in the second embodiment does not need a guide because the mobile phone is smaller in size compared to the first clamp 18 in the first embodiment, and thus the first guide assembly and the second guide assembly are omitted, which will not be described here.

[0283] In some embodiments, at least part of the first base 181 of the first clamp 18 is hollow, so that different mobile phones or tablets can ensure that the electronic device 1 can be placed horizontally.

[0287] ​

[0288] In some embodiments, the second clamping portion 199 is in a reverse U-shaped structure, and the first clamping member is a second clamping hole 190 arranged on the reverse U-shaped structure.

The seventh positioning block 194 is arranged on the second unidirectional screw rod transmission mechanism 197. The second unidirectional screw rod transmission mechanism 197 can drive the seventh positioning block 194 to move towards or away from the eighth positioning block 195 in a second direction. The first direction and the second direction are arranged perpendicularly. The fifth positioning block 192, the sixth positioning block 193, the seventh positioning block 194, and the eighth positioning block 195 cooperatively form a receiving space which is suitable for the size of the charging device 2 and can clamp the charging device 2 centrally. The first direction is parallel to the Y-axis direction, and the second direction is parallel to the X-axis direction.

[0290] Therefore, since the second bidirectional screw rod transmission mechanism 196 is a bidirectional clamping positioning mechanism, it can move synchronously towards each other or away from each other in the first direction. Thus, the charging device 2 can be clamped and centered in the first direction, so that the charging device 2 can be installed centrally on the second clamp 19. The second unidirectional screw rod transmission mechanism 197 can drive the seventh positioning block 194 to move towards the eighth positioning block 195 in the second direction. Thus, the charging device 2 can be positioned to the side of the eighth positioning block 195. Moreover, the eighth positioning block 195 is arranged on the side of the second clamp 19 close to the second plug-pull mechanism 4, which can facilitate the alignment and plug-pull operation of the second plug-pull mechanism 4.

[0291] In some embodiments, the second bidirectional screw rod transmission mechanism 196 comprises a fifth screw rod 1961 and two fifth screw rod nuts. The fifth screw rod 1961 is divided into two segments along its length direction, one of which is provided with left-hand threads and the other of which is provided with right-hand threads. The two fifth screw rod nuts are respectively threadedly connected to the left-hand threads and the right-hand threads and are symmetrically arranged relative to the center point of the second clamp 19. It can be understood that the center point refers to the desired centering position of the second clamp 19 when clamping the charging device 2. When the charging device 2 is located at the centering position, it will be convenient for subsequent plugging and unplugging of the second plug-pull mechanism 4. The fifth screw rod 1961 extends along the first direction (Y-axis direction). The fifth positioning block 192 can be slidably connected to one of the fifth screw rod nuts, and the sixth positioning block 193 can be slidably connected to the other fifth screw rod nut, so as to support and limit the charging device 2 at different positions. When the fifth screw rod 1961 rotates, it synchronously drives the two fifth screw rod nuts to move towards each other or away from each other, thereby achieving the centering clamping of the charging device 2 in the first direction.

[0292] In some embodiments, the second bidirectional screw rod transmission mechanism 196 further comprises a third knob 1963 fixedly connected to one end of the fifth screw rod 1961. The third knob 1963 can be used to drive the fifth screw rod 1961 to rotate. It can be understood that in other embodiments, the third knob 1963 can be replaced by a motor, which is not limited herein.

[0293] In some embodiments, the second unidirectional screw rod transmission mechanism 197 comprises a sixth screw rod 1971 and a sixth screw rod nut 1972. The sixth screw rod 1971 extends along the second direction, which can be understood as the aforementioned X-axis direction. The sixth screw rod nut 1972 is connected to the sixth screw rod 1971. The seventh positioning block 194 can be slidably connected to the sixth screw rod nut 1972. When the sixth screw rod 1971 rotates, it can drive the sixth screw rod nut 1972 to move in the second direction, thereby driving the seventh positioning block 194 to move in the second direction, thereby clamping or releasing the charging device 2 located on the second clamp 19, and achieving clamping of the charging device 2 located on the second clamp 19.

[0294] In some embodiments, the second unidirectional screw rod transmission mechanism 197 further comprises a fourth moving block 1973 fixedly connected to the sixth screw rod nut 1972. The length direction of the fourth moving block 1973 extends along the first direction (Y-axis direction). The top surface of the fourth moving block 1973 is in the shape of a track. The seventh positioning block 194 can be slidably connected to the top surface of the fourth moving block 1973 and can slide along the first direction under the guidance of the fourth moving block 1973.

[0295] Thus, the seventh positioning block 194 can slide along the first direction, and thus can be clamped on different positions of the charging device 2 placed on the second clamp 19 as needed.

[0296] In some embodiments, the second one-way screw driving mechanism 197 further comprises a fourth knob 1974 fixedly connected to one end of the sixth screw rod 1971, and the fourth knob 1974 can drive the sixth screw rod 1971 to rotate. It can be understood that in other embodiments, the fourth knob 1974 can be replaced by a motor, which is not limited here.

[0297] In some embodiments, the second clamp 19 further comprises a second fixed block 198, which also extends along the first direction (Y-axis direction). The top surface of the second fixed block 198 is track-shaped, and the eighth positioning block 195 can be slidingly connected to the top surface of the second fixed block 198 and can slide along the first direction under the guidance of the second fixed block 198.

[0298] Thus, the eighth positioning block 195 can slide along the first direction, and thus can be clamped on different positions of the charging device 2 placed on the second clamp 19 as needed.

[0299] In some embodiments, the second clamp 19 comprises two second clamping portions 199, which are respectively arranged on opposite sides of the second base 191. In the present embodiment, the second clamping portion 199 is inverted U-shaped. Each second clamping portion 199 is provided with a second clamping hole 190, which can be clamped with the second clamping protrusion 9223a on the second clamping jaw 9223. It can be understood that in other embodiments, the positions of the second clamping protrusion 9223a and the second clamping hole 190 can be interchanged, i.e., the second clamping protrusion 9223a can be arranged on the second clamping portion 199, and the second clamping hole 190 can be arranged on the second clamping jaw 9223. Alternatively, the second clamping jaw 9223 is provided with the second clamping hole 190 and the second clamping protrusion 9223a, and correspondingly, the second clamping portion 199 is provided with another second clamping protrusion 9223a and another second clamping hole. This is not limited here.

[0300] In some embodiments, at least part of the second base 191 of the second clamp 19 is hollow, so that different mobile phones or tablets can be placed horizontally to ensure that the charging device 2 can be placed horizontally.

[0301] In some embodiments, please refer to FIG. 25The second test position 11 is in a plate structure. The second test position 11 is provided with a second positioning pin for the second clamp 19.

When the second positioning pin is inserted into the second positioning hole 1911, the second clamp 19 can be accurately positioned on the second test position 11. Among them, the second clamp 19 and the second test position 11 are accurately positioned by the second positioning pin and the second positioning hole 1911, which is one of the aforementioned reference points 15.

[0302] Therefore, the accurate positioning of the second clamp 19 and the second test position 11 provides convenience for the second transfer device 92 to transfer the charging device 2 and the visual alignment and plugging work between the second plugging mechanism 4 and the charging device 2.

[0303] In some embodiments, the second test position 11 is also provided with an air cooling device 16 arranged for the second test position 11, which is arranged on the side of the second test position 11. FIG. 25 As can be seen, the air cooling device 16 arranged for the second test position 11 is located on the side of the second test position 11, so that the air cooling device 16 can air cool and dissipate heat for the charging device 2 located on the second test position 11 from the side of the second test position 11.

[0304] In some embodiments, the second test position 11 is also provided with a push cylinder 110, and the side of the second clamp 19 adjacent to the push cylinder 110 is provided with a connecting port 112, which is fixed relative to the second base 191. When the charging device 2 is a charger, the charging device 2 can be connected to the connecting port 112 through an adapter, and the other side of the connecting port 112 can be a plug pin or a jack. When the charging device 2 needs to be connected to the power grid, the push cylinder 110 pushes out the jack or plug pin matched with the current charging device 2, and is inserted into the plug pin or jack on the other side of the connecting port 112.

[0352] Therefore, in the present application, the second three-axis moving mechanism 41 can realize three-axis movement, the third plug module 43 can fix the second connecting head 702 of the data line 7, and the second visual device 42 can position the relative position between the second connecting head 702 of the data line 7 and the plug interface of the charging device 2. Through the cooperation of the second three-axis moving mechanism 41, the third plug module 43 and the second visual device 42, the second connecting head 702 of the data line 7 can be stably fixed, and the plug-in automation can be realized, and the plug-in accuracy is high and the reliability is high.

[0353] In some embodiments, the second three-axis moving mechanism 41 includes a second X-axis moving mechanism 411, a second Y-axis moving mechanism 412 and a second Z-axis moving mechanism 413. The second X-axis moving mechanism 411, the second Y-axis moving mechanism 412 and the second Z-axis moving mechanism 413 each include a motor and a screw transmission mechanism. The second X-axis moving mechanism 411 is arranged on the screw nut of the second Y-axis moving mechanism 412, and the second Z-axis moving mechanism 413 is arranged on the screw nut of the second X-axis moving mechanism 411.

[0354] Therefore, the second X-axis moving mechanism 411, the second Y-axis moving mechanism 412 and the second Z-axis moving mechanism 413 each adopt a screw transmission mechanism, which has the advantages of high-precision positioning, high-transmission efficiency, high rigidity, strong bearing capacity, smoothness, low noise, long service life, low maintenance, compact structure, fine adjustment, high resolution, etc.

[0355] In some embodiments, a Y-axis moving guide mechanism is further arranged between the second X-axis moving mechanism 411 and the second Y-axis moving mechanism 412, and an X-axis moving guide mechanism is further arranged between the second Z-axis moving mechanism 413 and the second X-axis moving mechanism 411. A Z-axis moving guide mechanism is arranged on the second Z-axis moving mechanism 413.

[0356] Therefore, the movement of the second three-axis moving mechanism 41 in the X-axis, Y-axis and Z-axis can be more smooth and stable.

[0357] It should be noted that the third plug module 43 has the same structure or similar structure as the first plug module 33, and will not be described again.

[0358] It should be noted that, FIG. 30The position of the second visual device 42 is only used to show that the second plug-pull mechanism 4 has a visual function. In fact, the second visual device 42 does not move with the second three-axis moving mechanism 41. In operation, when the second visual device 42 scans the position of the plug interface of the charging device 2, the coordinate position of the plug interface of the charging device 2 is obtained. Then, the second three-axis moving mechanism 41 moves the position of the third plug-pull module 43 or the position of the third plug-pull module 43 so that the position of the third plug-pull module 43 is aligned with the plug interface of the charging device 2 for plug-in or the position of the third plug-pull module 43 is aligned with the plug interface of the charging device 2 for plug-in.

[0359] In some embodiments, referring again to FIG. 1 , the image acquisition module 13 is arranged above the first test position 10. For example, the image acquisition module 13 is arranged above the first test position 10 through a reverse U-shaped support. The image acquisition module 13 is used to take a screen picture of the electronic device 1 located at the first test position 10. The control center 6 obtains the charging icon and / or the current power of the electronic device 1 according to the screen picture of the electronic device 1 taken by the image acquisition module 13. The control center 6 determines whether the electronic device 1 starts fast charging during the charging process of the charging device 2 to the electronic device 1 in combination with the charging icon, the charging current, the charging voltage and the charging protocol.

[0360] Therefore, in the present application, in combination with the charging icon of the electronic device 1 and the charging current measured by the current measuring element, it can be more accurately judged whether the electronic device 1 enters the fast charging mode. In addition, through the photographing, the power during the charging process of the electronic device 1 can be obtained, which provides a judgment basis for the execution of different test cases.

[0361] It can be understood that in the present application, the first test position 10, the first plug-pull mechanism 3, the second plug-pull mechanism 4, the second test position 11 and the camera of the image acquisition module 13 are all four and have a one-to-one correspondence, that is, one first test position 10, one first plug-pull mechanism 3, one second plug-pull mechanism 4, one second test position 11 and one camera of the image acquisition module 13 are correspondingly arranged. In other embodiments, the number of the first test position 10, the first plug-pull mechanism 3, the second plug-pull mechanism 4, the second test position 11 and the camera of the image acquisition module 13 is not limited, and the corresponding relationship is also not limited. For example, the number of the camera of the image acquisition module 13 does not correspond to the number of the first test position 10, and the image acquisition module 13 can move in the width direction of the rack 17 so as to take the screen picture of different first test positions 10.

[0362] Please refer to FIG. 31 , FIG. 31Fig. 6 shows a schematic diagram of the connection of the test device 5 and the cable 703 of the data line 7. It should be noted that the cable 703 at least includes a power line VBUS, a ground line GND, a data line D+, a data line D-, a configuration channel (CC) and a sideband use (SBU). The above six lines of the cable 703 are fixed on the PCB board and then connected with the test device 5. Specifically, the test device 5 includes a measurement and analysis module 50, which includes a current measurement element 51, a first resistor R1 connected in series on the power line VBUS, a voltage measurement element 52 connected between the power line VBUS and the ground line GND to obtain the charging voltage in the charging process of the charging device 2 to the electronic device 1, and a logic analyzer 53, different channels of which are connected with the data line D+, the data line D-, the configuration channel CC and the sideband use SBU, respectively. The logic analyzer 53 determines the charging protocol in the charging process of the charging device 2 to the electronic device 1 according to the signals of the data line D+, the data line D-, the configuration channel CC and the sideband use SBU.

[0363] Therefore, in the present application, by connecting different elements of the test device 5 to different lines of the cable 703, different parameters or signals in the charging process can be obtained.

[0364] It can be understood that the logic analyzer 53 can be placed in the square box of the test device 5 as shown in Fig. 6, or the logic analyzer 53 can also be placed together with the control center 6 in the rack 17, which is not limited here. FIG. 2

[0365] Next, the working principle of the test device 5 is introduced.

[0366] In some embodiments, the charging data includes the charging current, the charging voltage and the charging protocol, and the control center 6 determines the charging compatibility between the charging device 2 and the electronic device 1 according to the charging current, the charging voltage and the charging protocol.

[0367] Therefore, by the charging current, the charging voltage and the charging protocol, the charging compatibility between the charging device 2 and the electronic device 1 can be judged from multiple aspects, which is more accurate and can reduce the misjudgment rate.

[0368] ​VBUS is the positive pole of the power supply and is used to transmit power. The ground wire GND is the negative pole of the power supply and is used to form a closed loop with VBUS. Current flows from VBUS into the electronic device 1 and flows back to the power supply through GND. The data line D+ and the data line D- are differential data lines and are used for USB 2.0 data transmission. In a charging line, they can be omitted or short-circuited (pretending to be data transmission lines). USB 3.0 and above versions will additionally increase the super-speed differential pair (SS_TX / SS_RX) and coexist independently with the data line D+ and the data line D-. CC is unique to the Type-C interface and is responsible for connection detection, direction identification, and fast charging protocol negotiation. When the first connecting head 701 of the data line 7 is inserted into the electronic device 1, the CC pin is used to identify the insertion direction of the first connecting head 701. The PD protocol message is transmitted through the CC line to dynamically adjust the voltage / current (such as from 5V to 20V). Only the charging line with the CC line supports USB PD fast charging. The cheap line may omit the CC line, resulting in the inability to trigger fast charging. SBU is a backup channel of the Type-C interface and is used for special function extension. Non-USB signals (such as DisplayPort video and audio) are transmitted through SBU. In practical applications, if the CC line is damaged or missing, the electronic device 1 can only charge at 5V. The short circuit or breakage of the D+ / D- line will result in the inability to identify a U disk, etc.

[0369] In some embodiments, different channels of the logic analyzer 53 are respectively connected to the data line D+, the data line D-, the CC line, and the SBU line. For example, the first channel and the second channel of the logic analyzer 53 are respectively connected to the data line D+ and the data line D- for detecting the USB 2.0 protocol or private fast charging handshake signals (such as pulse modulation of SCP). The third channel of the logic analyzer 53 is connected to the CC line for capturing the BMC (Biphase Mark Coding) encoded signal of the USB PD protocol. The fourth channel of the logic analyzer 53 is connected to the SBU line for monitoring alternative modes (such as DisplayPort) or auxiliary communication. In addition, the GND of the logic analyzer 53 needs to be directly connected to the GND of the data line 7 to avoid common mode interference.

[0370] The logic analyzer 53 continuously monitors the signals of the data line D+, the data line D-, the configuration channel CC, and the auxiliary signal line SBU, and analyzes the signal curve to determine whether to normally enter the fast charging protocol: PD, UCFS, SCP, etc. In the process of judging the charging protocol, the logic analyzer 53 first synchronously captures the D+, D-, CC, and SBU waveforms (sampling rate ≥ 24MHz). If the CC line is active, the USB PD protocol is preferentially analyzed. If the D+ / D- pulse / jump is detected, the SCP / UCFS characteristics are checked, as follows:

[0371] The signal characteristics and judgment conditions of the USB PD protocol (USB Power Delivery) are as follows. The key signal line of the USB PD protocol (USB Power Delivery) is the CC line. The signal characteristics of the USB PD protocol are BMC coding and data packet structure. The BMC coding refers to the use of biphase mark coding (BMC) on the CC line, and the signal is a periodic high-low level alternation. The data packet structure includes a start frame (SOP), a message header (Header), data objects (DataObjects), CRC check, and the like. The judgment conditions of the USB PD protocol include CC line activity detection, protocol decoding verification, and voltage / current switching. The CC line activity detection is that the logic analyzer 53 captures the periodic BMC signal (non-fixed level) on the CC line. The protocol decoding verification is that the decoded Source_Capabilities (power capability declaration) and Request (device request) messages exist. Both parties exchange Accept (accept) and PS_RDY (power supply preparation completion) confirmation messages. Voltage / current switching is that the VBUS voltage is switched from 5V to the target value (such as 9V, 12V, and 20V) after the protocol handshake. The abnormal condition is that there is no CC signal or CRC check fails. That is, when there is no CC signal or CRC check fails, it is determined that the USB PD protocol is not entered.

[0372] The key signal lines of the SCP protocol are the data lines D+ and D-. The signal characteristics of the SCP protocol are the handshake phase: the data line D+ is pulled high to a specific voltage (such as 3.3V or 5V) by the charging device 2, and then the data line D- responds to a pulse signal. The charging phase: the data line D+ maintains a high level (such as 5V), and the data line D- is periodically pulsed (at a frequency of about 1kHz). The judgment condition of the SCP protocol is that the data line D+ voltage jumps, that is, the data line D+ jumps from 0V to 3.3V / 5V (the charging device 2 sends a handshake signal); the data line D- pulse response: the data line D- outputs a pulse sequence of a specific frequency after the handshake. The power line VBUS voltage rises to 4.5V (SCP low-voltage direct charging) or higher (such as 10V). The abnormal condition of the SCP protocol is that there is no D+ jump and pulse loss. No D+ jump indicates that the charging device 2 or the electronic device 1 does not support the SCP protocol. Pulse loss refers to that the cable 703 impedance is too high or the contact is poor, resulting in handshake failure.

[0373] The key signal lines of the UCFS protocol are the data line D+, the data line D-, or the CC line. The signal characteristics of the UCFS protocol are: digital communication and key exchange. The digital communication refers to sending a differential digital signal (similar to the I2C protocol) through the data line D+ and the data line D-; the key exchange refers to the electronic device 1 and the charging device 2 exchanging an encrypted key to confirm authorization. The judgment conditions of the UCFS protocol are the D+ / D- differential signal, the key verification success, and the VBUS high-voltage large current. Among them, the D+ / D- differential signal refers to detecting a periodic digital communication waveform (non-USB data); the key verification success refers to decoding to show that the authorization authentication is passed (the reverse protocol format is required); the VBUS high-voltage large current refers to the VBUS maintaining 5V but the current significantly increasing (such as 5V@5A). The abnormal diagnosis of the UCFS protocol includes two cases, namely, no digital communication and authentication failure. No digital communication refers to the cable 703 not passing the MFI / UCFS authentication. The authentication failure refers to the key mismatch, triggering a protection mechanism (such as limiting the current to 5V@2A).

[0374] The control center 6 comprehensively judges the charging compatibility of the current electronic device 1 and the current charging device 2 by obtaining the charging current measured by the current measuring element 51, the charging voltage measured by the voltage measuring element 52, the charging protocol analysis result of the logic analyzer 53, and the charging icon obtained by the image acquisition module 13. The charging compatibility includes electrical parameter compatibility verification and charging protocol handshake analysis. Among them, the electrical parameter compatibility verification includes voltage matching check and current capacity evaluation.

[0375] The voltage matching check is to confirm whether the charging voltage (such as 5V / 9V / 12V / 15V / 20V) is within the input voltage range supported by the electronic device 1. If the electronic device 1 supports the PD / PPS protocol, it is also necessary to check whether the charging device 2 supports voltage continuous adjustment (such as 20mV step of PD 3.0).

[0376] The current capacity evaluation includes maximum current comparison and overload protection threshold. The maximum current comparison refers to the charging device 2 output current ≥ the rated input current of the electronic device 1.

[0377] The overload protection threshold refers to the maximum current of the charging device 2 should not exceed the overcurrent protection threshold of the electronic device 1 (such as 110%-120% of the electronic device 1).

[0378] The charging protocol handshake analysis includes protocol type identification and communication process verification. The protocol type identification refers to detecting whether it matches the basic protocols QC2.0 / 3.0, PD2.0 / 3.1, VOOC, etc., and whether it matches the proprietary protocols: such as Huawei SCP (4.5-10V / 4.5A), OPPO VOOC (5V / 5A).

[0379] The communication process verification is to analyze the Source_Capabilities message of USB-PD, and confirm whether the voltage / current combination is received by the electronic device 1; for the QC protocol, it is detected whether the voltage modulation of the data line D+ and the data line D- successfully triggers (such as 0.6V-3.3V negotiation of QC3.0).

[0380] Therefore, when making a charging compatibility decision, it is judged whether the voltage is matched, the current capacity is sufficient, and the protocol handshake is successful. When the voltage is matched, the current capacity is sufficient, and the protocol handshake is successful, the compatible judgment result is output. When the voltage is not matched, the current capacity is not sufficient, or the protocol handshake is not successful, the incompatible judgment result is output.

[0381] FIG. 32 An example is shown to illustrate the structure of the control center 6 provided in the embodiment of the application.

FIG. 32 The various components shown in FIG. 1 can be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and / or application specific integrated circuits.

[0392] Next, an example flow of the charging compatibility test method in the embodiments of the present application is introduced.

[0393] Please refer to FIG. 33 , FIG. 33 is an example flowchart of the charging compatibility test method in the embodiments of the present application. The charging compatibility test method can be applied to the charging compatibility test device 1000 described above.

[0394] Step S1: Information input of electronic devices and charging devices.

[0395] Specifically, the information of one or more electronic devices to be detected is input into the database, including product type, product model, fast charging protocol, and power key position, etc. The information of one or more charging devices to be detected is input into the database, including product type, product model, and fast charging protocol, etc.

[0396] The product type of the electronic device can be a mobile phone, a tablet, etc. The product model of the electronic device refers to the specific model of the corresponding product type. The charging protocol of the electronic device refers to the fast charging protocol supported by the electronic device. The input information can be manually input or scanned input, which refers to scanning the bar code or two-dimensional code on the electronic device to input the relevant information.

[0397] Wherein, the product type of the charging device can be a power bank or a charger, the product model of the charging device refers to the specific model of the corresponding product type, and the fast charging protocol of the charging device refers to the fast charging protocol supported by the charging device. Wherein, the input information can be manually input or scanned input, and the scanned input refers to scanning the bar code or two-dimensional code on the charging device to input the relevant information.

[0398] Step S2: loading electronic devices and charging devices.

[0399] Specifically, the electronic device is manually loaded into the first clamp, and the first clamp is placed into the first storage bin. The bin number of the first clamp in the first bin position of the first storage bin, the product model of the electronic device, and the product serial number of the electronic device are input. The charging device is manually loaded into the second clamp, and the second clamp is placed into the second storage bin. The bin number of the second clamp in the second bin position of the second storage bin, the product model of the charging device, and the product serial number of the charging device are input.

[0400] Wherein, the information input method for the electronic device and the first clamp can be, but is not limited to, manually input or scanning the bar code or two-dimensional code on the electronic device and the first clamp to perform code scanning input.

[0401] Wherein, the information input method for the charging device and the second clamp can be, but is not limited to, manually input or scanning the two-dimensional code or bar code on the charging device and the second clamp to perform code scanning input.

[0402] Step S3: configuring test sequences.

[0403] Specifically, the process of configuring test sequences is a permutation and combination process, that is, the same electronic device is sequentially matched with different charging devices, or the same charging device is sequentially matched with different electronic devices, so as to measure the charging compatibility between the same electronic device and different charging devices or the charging compatibility between the same charging device and different electronic devices. For example, the first test sequence is the first bin position (number X1) of the first storage bin VS the second bin position (number Y1) of the second storage bin, and the test cases are 1, 2, 3, etc. The second test sequence is the first bin position (number X2) of the first storage bin VS the second bin position (number Y2) of the second storage bin, and the test cases are 2, 3, 6, etc.

[0404] Wherein, as before, the first storage bin includes a plurality of first bin positions, and the second storage bin includes a plurality of second bin positions. As before, the test cases can be, but are not limited to, low-power fast charging identification test, high-power fast charging identification test, super-high-power fast charging identification test, fast plug-in test, slow plug-in test, and full charging process test, etc. The specific test cases can be selected according to the actual charging compatibility requirements.

[0405] Step S4: sequentially taking out a test sequence from the database, loading the corresponding configuration information.

[0406] The configuration information includes target charging voltage, target charging current, and target charging protocol corresponding to the test sequence.

[0407] Step S5: according to the current test sequence, the first transfer mechanism takes out the electronic device from the corresponding first bin of the first storage bin and feeds it to the first test position. The first transfer mechanism presses the power button of the electronic device by the button mechanism during feeding to start the electronic device. The control center controls the first plug-in module of the first plug-in mechanism to plug into the plug-in interface of the electronic device.

[0408] Step S6: according to the current test sequence, the second transfer mechanism takes out the charging device from the corresponding second bin of the second storage bin and feeds it to the second test position. The control center controls the third plug-in module of the second plug-in mechanism to plug into the plug-in interface of the charging device.

[0409] It should be noted that in some embodiments, steps S5 and S6 are performed simultaneously.

[0410] Step S7: control the image acquisition module to take a picture of the screen of the electronic device.

[0411] Step S8: according to the screen picture of the electronic device, obtain the current power of the electronic device, and determine whether the power is over limit, insufficient or normal. When the current is over limit, go to step S9; when the current is insufficient, go to step S10; when the power is normal, go to step S11.

[0412] Step S9: discharge the electronic device. Specifically, the control center controls the second plug-in module of the first plug-in mechanism to plug into the plug-in interface of the electronic device to discharge the electronic device. After a preset time, return to step S7.

[0413] Step S10: charge the electronic device. Specifically, the control center controls the first plug-in module of the first plug-in mechanism to plug into the plug-in interface of the electronic device to charge the electronic device. After a preset time, return to step S7.

[0414] Step S11: sequentially take out a test sequence, control the first plug-in mechanism 3 corresponding to the first test position and the image acquisition module 13 corresponding to the first test position to act. After step S11, steps S121, S122 and S123 are performed simultaneously.

[0415] Step S121: obtain the shooting video of the charging process from the image acquisition module. After step S121, go to step S131.

[0416] Step S131: Frame-by-frame detection of the charging icon in the photographed video. After step S131, proceed to step S14.

[0417] Specifically, the frame-by-frame detection of the charging icon in the photographed video can obtain the charging amount and the charging icon, which is divided into a fast charging icon and a regular charging icon.

[0418] Step S122: Obtain the voltage curve and the current curve from the voltage measuring element and the current measuring element, respectively. After step S122, proceed to step S14.

[0419] Step S123: Obtain the USB signal waveform during the charging process from the logic analyzer.

[0420] Step S133: Perform charging protocol analysis according to the USB signal waveform of the logic analyzer.

[0421] Step S14: Determine the charging compatibility between the electronic device and the charging device in the current test sequence based on the charging icon, the voltage curve, the current curve, and the charging protocol.

[0422] Specifically, determine whether the voltage is matched, whether the current capacity is sufficient, and whether the protocol handshake is successful. When the voltage is matched, the current capacity is sufficient, and the protocol handshake is successful, output a compatible determination result. When the voltage is not matched, the current capacity is not sufficient, or the protocol handshake is not successful, output an incompatible determination result.

[0423] Step S15: Determine whether all test cases of the current test sequence have been executed. If yes, determine that the current test sequence has been executed, and display the test data. If no, return to step S11.

[0424] Step S16: Determine whether all test sequences have been executed. If yes, end the test. If no, return to step S4.

[0425] Thus, through the above process, the charging compatibility test between the same electronic device and N charging devices or the charging compatibility test between the same charging device and N electronic devices can be completed, and full-automatic testing is achieved.

[0426] Please refer to FIG. 34 , FIG. 34 is an execution flowchart of one example test sequence in the embodiments of the present application. The test sequence includes multiple test cases, such as, but not limited to, test cases including startup test, ≤5% low power fast charging recognition test, ≥95% power fast charging recognition test, 99% power fast charging recognition test, full charging process test, electronic device slow insertion test, electronic device fast insertion test, etc. The details are as follows:

[0427] Step S21: Start the test. The main purpose of this step is to make preparations before the test, such as performing the aforementioned steps S1, S2 and S3, and then starting the test.

[0428] Step S22: Start the test.
