Description

Technical Field

[0001] This utility model belongs to the field of charging equipment testing technology, and in particular relates to a wireless charging equipment production line for testing equipment. Background Technology

[0002] A wireless charger is a charger that does not require a traditional charging cable to connect to the terminal device that needs charging. It uses the latest wireless charging technology to transmit electrical energy by using the magnetic field generated between coils. The wireless charging system mainly uses the principle of electromagnetic induction, and achieves energy transfer through energy coupling via coils.

[0003] To ensure product performance and safety, wireless charging devices must undergo a series of tests. However, current testing of different functions of wireless charging devices requires multiple devices with different testing capabilities, and involves multiple manual loading and unloading operations between these devices. This makes the testing process cumbersome and time-consuming. Furthermore, the testing structures used in current equipment are fixed, thus only applicable to wireless charging devices of fixed specifications and sizes, resulting in poor applicability. Utility Model Content

[0004] The purpose of this application is to provide a testing device and a wireless charging device production line, aiming to solve the problem of how to improve the applicability and testing efficiency of the testing device.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

Multiple lifting mechanisms and testing mechanisms are provided, each lifting mechanism corresponding to one of each testing mechanism. Each testing mechanism is spaced apart along the first direction and is used to detect different parameters of the workpiece under test. The fixing mechanism has multiple position states corresponding to each testing mechanism. When the fixing mechanism is in any of the stated position states, the corresponding testing mechanism performs testing on the workpiece under test.

[0007] In some embodiments, the frame includes a support frame with lifting space, a plurality of support frames are spaced apart along the first direction, each of the lifting mechanisms is connected to each of the support frames, and each of the lifting spaces is connected to form the test channel.

[0008] In some embodiments, the support frame is connected to a linear motion mechanism, and the lifting mechanism is connected to the output end of the linear motion mechanism. The linear motion mechanism is used to drive the lifting mechanism to move along a third direction, which is perpendicular to the first direction.

[0009] In some embodiments, the fixing mechanism includes a tray slidably connected to the slide table and a clamp detachably connected to the tray, the clamp being used to hold the test piece.

[0010] In some embodiments, the fixture includes a support plate for carrying the test piece, a jaw rotatably connected to the support plate, and a rotation drive located below the support plate. The support plate has a first clearance hole through which the rotation drive passes. The output end of the rotation drive passes through the first clearance hole and is connected to the jaw. The rotation drive is used to drive the jaw to rotate so that the jaw closes or separates from the support plate.

[0011] In some embodiments, the fixing mechanism further includes a lifting mechanism located below the support plate and corresponding to the test piece, and a probe assembly connected to the lifting mechanism. The support plate is provided with a second clearance hole through which the probe assembly passes. The lifting mechanism is used to drive the probe assembly to rise and fall, so that the probe assembly is connected to or separated from the test piece.

[0012] In some embodiments, the testing device further includes a guide rail passing through the testing channel and extending along the first direction, the guide rail being spaced apart from the slide table, one end of the tray being slidably connected to the slide table, and the other end of the tray being slidably connected to the guide rail.

[0013] In some embodiments, the device under test is a wireless charging device, and the testing mechanism is a fast charging testing device, an NFC testing device, or a coil testing device, and at least two of the testing mechanisms are different.

[0014] In some embodiments, the coil testing device includes a plurality of test coils, each test coil having a different power, and each test coil is used to test the device under test having a different charging power.

[0015] Secondly, a wireless charging equipment production line is provided, which includes the testing equipment described above.

[0016] The testing equipment provided in this application allows for height adjustment of the testing mechanism via a lifting mechanism, thereby flexibly adjusting the relative position of the testing mechanism and the test piece. This enables the testing mechanism to be applicable to test pieces of different models and sizes, thus improving the applicability of the testing equipment. Furthermore, by setting up multiple testing mechanisms, the test piece can be moved to the bottom of each testing mechanism via a sliding table for testing. This allows for the simultaneous testing of multiple parameters of the test piece within a single device, avoiding frequent loading and unloading, simplifying the testing process, and thus improving testing efficiency.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] Please see Figures 1 to 4This application provides a testing device, including a frame 10 with a test channel 11, a slide 20 passing through the test channel 11 and extending along a first direction, a fixing mechanism 30 slidably disposed on the slide 20 along the first direction and used to fix a test piece 200, a testing mechanism 40 slidably disposed in the test channel 11, and a lifting mechanism 50 connected to the frame 10 and used to drive the testing mechanism 40 to rise and fall along a second direction. Multiple lifting mechanisms 50 and testing mechanisms 40 are provided, each lifting mechanism 50 corresponding to each testing mechanism 40. Each testing mechanism 40 is spaced apart along the first direction and each testing mechanism 40 is used to detect different parameters of the test piece 200. The fixing mechanism 30 has multiple position states corresponding to each testing mechanism 40. When the fixing mechanism 30 is in any position state, the corresponding testing mechanism 40 tests the test piece 200.

[0029] It should be noted that the device under test 200 provided in this application embodiment is a wireless charging device. The wireless charging device can achieve wireless charging based on the phenomenon of electromagnetic induction. Specifically, the wireless charging device has a built-in transmitting coil. When current passes through the transmitting coil, a magnetic field is generated. When another unpowered receiving coil is placed in this magnetic field, a current will be generated in that coil. When the wireless charging device charges an electronic device, the receiving coil inside the electronic device receives the magnetic field and generates electromagnetic induction, thereby generating an induced current. After rectification, this current charges the electronic device.

[0030] Understandably, by sliding the fixing mechanism 30 onto the slide table 20, the fixing mechanism 30 has position states corresponding to each test mechanism 40. When the test mechanism 40 is in any position state, the corresponding test mechanism 40 is driven by the lifting mechanism 50 to move toward the fixing mechanism 30 and test the test piece 200. The distance between the test mechanism 40 and the test piece 200 can be adjusted, thereby improving the comprehensiveness and accuracy of the test.

[0031] The testing equipment provided in this application allows for height adjustment of the testing mechanism 40 via a lifting mechanism 50, thereby flexibly adjusting the relative position of the testing mechanism 40 and the test piece 200. This enables the testing mechanism 40 to be applicable to test pieces 200 of different models and sizes, thus improving the applicability of the testing equipment. Furthermore, by setting multiple testing mechanisms 40, the test piece 200 can be moved to the bottom of each testing mechanism 40 via a slide table 20 for testing. This allows for simultaneous testing of multiple parameters of the test piece 200 within a single device, avoiding frequent loading and unloading, simplifying the testing process, and thus improving testing efficiency.

[0032] Optionally, the slide 20 in this embodiment of the application can be an electric slide 20, which can drive the fixed structure to move, thereby improving testing efficiency.

[0033] In addition, the testing equipment in this embodiment may also include a control mechanism, which is communicatively connected to the slide table 20, the fixing mechanism 30, the testing mechanism 40, and the lifting mechanism 50. Through the control of the control mechanism, the testing equipment of this application can automatically transfer and test the test piece 200 without manual assistance, greatly improving testing efficiency. Furthermore, when the fixing mechanism 30 is located outside the testing channel 11, the test piece 200 can be loaded or unloaded without being limited by the space of the testing channel 11, thereby improving the convenience of loading and unloading.

[0034] In some embodiments, the frame 10 includes a support frame 12 with a lifting space 121. Multiple support frames 12 are spaced apart along a first direction. Each lifting mechanism 50 is connected to each support frame 12, and each lifting space 121 communicates to form a test channel 11. By providing multiple support frames 12, and connecting each lifting mechanism 50 and each test mechanism 40 to each support frame 12, each test mechanism 40 remains independent, avoiding mutual influence and interference, and ensuring the normal operation of the test.

[0035] Specifically, the frame 10 also includes a base, the slide 20 is disposed on the base, and the support frame 12 includes a crossbeam and a column disposed above the slide 20. One end of the column is connected to the crossbeam, and the other end of the column is connected to the base. The column supports the crossbeam to a preset height, thereby forming a lifting space 121 between the crossbeam and the base.

[0036] In some embodiments, the support frame 12 is connected to a linear motion mechanism 60, and the lifting mechanism 50 is connected to the output end of the linear motion mechanism 60. The linear motion mechanism is used to drive the lifting mechanism 50 to move along a third direction, which is perpendicular to the first direction. By setting the linear motion mechanism 60 and the lifting mechanism 50, the test mechanism 40 can be driven to make position adjustments in multiple directions, which can more accurately and comprehensively cover the test points and effectively improve test efficiency and accuracy. Optionally, the first direction, the second direction, and the third direction are perpendicular to each other. It should be noted that the lifting mechanism 50 and the linear motion mechanism 60 in this embodiment can be a linear drive module.

[0037] In some embodiments, the fixing mechanism 30 includes a tray 31 slidably connected to the slide table 20 and a clamp 32 detachably connected to the tray 31. The clamp 32 is used to hold the test piece 200. By detachably connecting the clamp 32 to the tray 31, it is convenient to install and remove the clamp 32. The clamp 32 can be modularly designed, and corresponding clamps 32 can be equipped for wireless charging devices of different sizes or types, thereby improving the adaptability and comprehensiveness of the fixing structure. Furthermore, it eliminates the need to replace the entire testing equipment for different wireless charging devices, thus saving costs.

[0038] Optionally, the pallet 31 is provided with a positioning pin, and the fixture 32 includes a base plate 326. The base plate 326 is provided with a positioning hole that matches the positioning pin. The positioning pin is inserted into the positioning hole to achieve a detachable connection between the fixture 32 and the pallet 31. The connection method is simple and can improve the efficiency of disassembly and assembly.

[0039] In some embodiments, the fixture 32 includes a support plate 321 for carrying the test piece 200, a gripper 322 rotatably connected to the support plate 321, and a rotation drive 323 located below the support plate 321. The support plate 321 is provided with a first clearance hole for the rotation drive 323 to pass through. The output end of the rotation drive 323 passes through the first clearance hole and is connected to the gripper 322. The rotation drive 323 is used to drive the gripper 322 to rotate so that the gripper 322 closes or separates from the support plate 321. Understandably, when the rotation drive 323 drives the gripper 322 to rotate toward the surface of the support plate 321, that is, the gripper 322 closes with the support plate 321, the test piece 200 on the support plate 321 can be clamped. When the rotation drive 323 drives the gripper 322 to rotate toward the surface of the support plate 321, that is, the gripper 322 separates from the support plate 321, the test piece 200 on the support plate 321 can be released.

[0040] Understandably, the gripper 322 may include a hinge end and a clamping end. The hinge end of the gripper 322 is rotatably connected to the edge of the support plate 321 via a rotating shaft. The clamping end of the gripper 322 is used to apply force to the workpiece 200 and clamps the workpiece 200 together with the support plate 321. The output end of the rotation drive 323 is connected to the position between the hinge end and the clamping end. By applying force to the position between the hinge end and the clamping end through the rotation drive 323, the clamping end can be driven to rotate around the hinge end. Optionally, the rotation drive 323 may be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, or other telescopic components or structures.

[0041] In another specific embodiment, two grippers 322 are spaced apart, and two rotation drive members 323 are correspondingly arranged. The test piece 200 is located between the two grippers 322. The two rotation drive members 323 drive the two grippers 322 to rotate respectively. The two grippers 322 are used to clamp the two ends of the test piece 200, thereby further improving the stability of the test piece 200.

[0042] In some embodiments, the fixing mechanism 30 further includes a lifting mechanism 324 located below the support plate 321 and corresponding to the test piece 200, and a probe assembly 325 connected to the lifting mechanism 324. The support plate 321 is provided with a second clearance hole 3212 for the probe assembly 325 to pass through. The lifting mechanism 324 is used to drive the probe assembly 325 to rise and fall, so that the probe assembly 325 can be connected or separated from the test piece 200. When the test piece 200 is clamped on the support plate 321, the lifting mechanism 324 starts to drive the probe assembly 325 to move toward the test piece 200 and electrically connects the probe assembly 325 to the connection port on the test piece 200. At this time, the test piece 200 is in a test state and can be tested. After the test is completed, the lifting mechanism 324 drives the probe assembly 325 to move downward, so that the probe assembly 325 is separated from the connection port on the test piece 200. Then the gripper 322 releases the test piece 200, and the test piece 200 can be unloaded. Optionally, the lifting mechanism 324 can be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, or other telescopic components or structures.

[0043] In addition, the surface of the support plate 321 has a limiting cavity 3213 for limiting the test piece 200. The limiting cavity 3213 can limit the test piece 200, further improving the stability of the test piece 200. Optionally, the shape of the limiting cavity 3213 is adapted to the outer contour of the test piece 200, that is, the limiting cavity 3213 can be a contoured cavity, thereby further improving the limiting effect. Understandably, the second clearance hole 3212 is provided in the limiting cavity 3213 and penetrates the bottom wall of the limiting cavity 3213.

[0044] In some embodiments, a presence sensor is also provided on the support plate 321. The presence sensor is communicatively connected to the control mechanism. The presence sensor is used to detect whether there is a test piece 200 to be clamped on the support plate 321 and generate a sensing signal. The control mechanism drives the slide table 20 to move according to the sensing signal, thereby moving the test piece 200 to the detection position.

[0045] Understandably, the support plate 321 and the base plate 326 are spaced apart, and the rotation drive 323 and the lifting mechanism 324 can be located in the space between the support plate 321 and the base plate 326. In addition, a quick-change module 327 is also provided on the base plate 326, through which the circuit and air circuit can be quickly replaced.

[0046] In some embodiments, the testing equipment further includes a guide rail 70 passing through the testing channel 11 and extending along a first direction. The guide rail 70 is spaced apart from the slide table 20. One end of the support plate 31 is slidably connected to the slide table 20, and the other end of the support plate 31 is slidably connected to the guide rail 70. The guide rail 70 can guide the movement of the fixing mechanism 30, thereby preventing the fixing mechanism 30 from deviating during movement.

[0047] In some embodiments, the device under test 200 is a wireless charging device, and the testing mechanism 40 is a fast charging testing device, an NFC (Near Field Communication) testing device, or a coil testing device, and at least two testing mechanisms 40 are different.

[0048] Specifically, the fast charging testing equipment includes a mobile phone or other terminal device. When the lifting mechanism 50 drives the mobile phone close to the wireless charging device under test, the wireless charging device charges the mobile phone. At this time, by analyzing the mobile phone, it can be determined whether the wireless charging device can perform fast charging. Optionally, the mobile phone can be connected to the lifting mechanism 50 via a quick clip, thereby enabling quick disassembly and replacement.

[0049] Specifically, NFC detection devices include NFC cards. Understandably, NFC technology is a near-field communication technology, and it may interfere with wireless charging devices during operation. NFC cards can simulate the coexistence of NFC devices and wireless charging devices in real-world scenarios. Testing can determine whether wireless charging devices interfere with the communication function of NFC cards during operation, such as causing the NFC card to fail to read properly or data transmission errors. This ensures that wireless charging devices do not affect the normal communication of other NFC devices in actual use.

[0050] Specifically, the coil detection device includes a metal foreign object and a test coil 41. Since the transmitting coil of the wireless charging device transfers energy to the test coil 41, and the metal foreign object will affect the energy transmission, by placing a metal foreign object in the charging area, the charging status of the wireless charging device when the foreign object is present can be detected, and the transmitting coil of the wireless charging device can also be detected.

[0051] In some embodiments, the coil testing device includes a plurality of test coils 41, each with a different power, and each test coil 41 is used to test a device under test 200 with a different charging power. Understandably, wireless charging devices typically have different charging powers, such as fast charging or slow charging. Setting test coils 41 with different power allows for adaptation to different charging powers, thereby improving the comprehensiveness and accuracy of the test. In a specific embodiment, the coil testing device includes test coils 41 with receiving power of 15W and 50W.

[0052] In some embodiments, the testing equipment includes multiple racks 10, which are spaced apart along a third direction to form multiple test channels 11. Multiple sets of slides 20, fixing mechanisms 30, testing mechanisms 40 and lifting mechanisms 50 are respectively provided, so that multiple test pieces 200 can be tested simultaneously, thereby further improving testing efficiency.

[0053] In some embodiments, the testing equipment further includes a chassis 80 with a testing chamber. The frame 10, slide 20, fixing mechanism 30, testing mechanism 40, and lifting mechanism 50 are all disposed inside the testing chamber. The chassis 80 can provide protection and prevent the test from being interfered with by external factors. In addition, the frame 10 includes loading and unloading stations for loading and unloading materials. The loading and unloading stations are disposed at one end of the slide 20 and are located outside the testing channel 11. The chassis 80 has a feed port 81 that communicates with the testing chamber. The feed port 81 corresponds to the loading and unloading station. When the fixing mechanism 30 moves to the loading and unloading station, the test piece 200 can be loaded onto the fixing mechanism 30 through the feed port 81, or the tested material can be unloaded from the fixing mechanism 30.

[0054] This utility model also proposes a wireless charging equipment production line, which includes testing equipment. The specific structure of the testing equipment is as described in the above embodiments. Since this wireless charging equipment production line adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0055] In summary, the testing equipment provided in this application allows for height adjustment of the testing mechanism 40 via the lifting mechanism 50, thereby flexibly adjusting the relative position of the testing mechanism 40 and the test piece 200. This enables the testing mechanism 40 to be applicable to test pieces 200 of different models and sizes, thus improving the applicability of the testing equipment. Furthermore, by setting multiple testing mechanisms 40, the test piece 200 can be moved to the bottom of each testing mechanism 40 via the slide table 20 for testing. This allows for simultaneous testing of multiple parameters of the test piece 200 within a single device, avoiding frequent loading and unloading, simplifying the testing process, and thus improving testing efficiency.

[0056] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
