Description
Technical Field
[0001] This utility model relates to the field of inductor testing technology, and in particular to an inductor combination testing device. Background Technology
[0002] With the rapid development of the electronics industry, inductors, as an indispensable and crucial component in circuits, directly affect the stability and reliability of the entire circuit system. To ensure the quality of inductors, comprehensive and accurate testing of their various parameters is essential. Traditional inductor testing methods typically rely on multiple single-function testing instruments to perform interlayer impedance testing, comprehensive performance testing, high-voltage testing, superimposed inductance testing, and DC bias testing, among others.
[0003] Because each test requires a separate testing device, when performing multiple data tests on an inductor, operators need to frequently disconnect the inductor from one testing device and connect it to another. This process is not only time-consuming but also prone to incorrect connections due to human error, thus affecting the accuracy of the test results. Furthermore, since each test is conducted independently, it is difficult to guarantee the consistency of all test conditions. Especially under the influence of factors such as ambient temperature and humidity, differences in results between different tests may occur, thereby affecting the evaluation of the inductor's true performance. Utility Model Content
[0004] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose an inductor combination testing device that can automatically test multiple parameters of an inductor in one go.

[0009] The control system is electrically connected to multiple testers and clamp assemblies respectively, and the control system is configured with multiple preset test modules. When the control system detects that the terminal is on any one or more of the clamp assemblies, it calls the preset test modules, and the preset test modules trigger multiple testers to test the inductor and record the test data.
[0010] In the aforementioned inductor assembly testing device, the clamping mechanism further includes a sensor electrically connected to the control system, the sensor being disposed on the clamp assembly; when the sensor detects that the terminal is on the clamp assembly, the sensor sends an electrical signal to the control system, the control system drives the clamp assembly to close, and after the clamp assembly closes, it invokes the preset test module.
[0011] In the aforementioned inductor assembly testing device, each clamp assembly includes a positioning structure and a clamping structure. The clamping structure is movably disposed above the positioning structure and has a first moving position and a second moving position. When the clamping structure moves to the first moving position, the clamp assembly is closed; when the clamping structure moves to the second moving position, the clamp assembly is opened.
[0012] In the aforementioned inductor assembly testing equipment, the clamping mechanism includes a first mounting base disposed on the workbench, the first mounting base having a plurality of first mounting slots, and the positioning structure being detachably disposed within the first mounting slots.
[0013] In the aforementioned inductor combination testing equipment, the first mounting base is further provided with multiple second mounting slots communicating with the first mounting slot, and the sensor is disposed in the second mounting slot; when the terminal is on the positioning structure, the sensor sends an electrical signal to the control system, the control system drives the clamping structure to move to the first moving position, and after the terminal is clamped between the positioning structure and the clamping structure, the preset test module is invoked.
[0014] In the aforementioned inductor assembly testing equipment, the first mounting base is further provided with a protective plate. The protective plate has a plurality of placement holes that correspond one-to-one with and communicate with the second mounting slot, and the protective plate can partially shield the clamping structure and the positioning structure.
[0015] In the aforementioned inductor combination testing equipment, the clamping mechanism further includes a second mounting base located above the first mounting base. The second mounting base is provided with multiple sets of drive structures that correspond one-to-one with the clamping structure. The drive structure is electrically connected to the control system, and the clamping structure is detachably located at the output end of the drive structure.
[0016] In the aforementioned inductor assembly testing equipment, a workpiece placement mechanism is included. The workpiece placement mechanism includes a workpiece placement plate movably disposed on the worktable and a scissor-type lifting platform disposed below the workpiece placement plate. The scissor-type lifting platform can drive the workpiece placement plate to move towards or away from the chuck assembly.
[0017] In the aforementioned inductor assembly testing equipment, the scissor-type lifting platform includes a lifting plate, which has multiple fixing holes and at least two limiting members detachably connected to the fixing holes. The workpiece placement plate is detachably connected to the fixing holes, and both ends of the workpiece placement plate abut against the limiting members.
[0018] In the aforementioned inductor combination testing equipment, the scissor-type lifting platform and the workpiece placement plate are provided in two sets, corresponding one to one. The workbench is also provided with a transfer placement plate arranged adjacent to the two sets of workpiece placement plates, and both the transfer placement plate and the workpiece placement plate are insulating plates.
[0019] Compared with the prior art, the present invention has at least the following beneficial effects:
[0020] 1. In this utility model, by integrating multiple testers on the same workbench and utilizing a control system and preset test modules, one-time automated testing of different parameters of inductors is achieved. This allows operators to simply connect the terminals to the clamping mechanism, and all subsequent testing steps are automatically completed by the equipment. This not only greatly shortens the testing time and improves work efficiency, but also ensures the accuracy of the test results.
[0021] 2. In this utility model, by configuring multiple preset test modules and multiple chuck assemblies that can be opened and closed and are electrically connected to the control system on the workbench, the control system can call different preset test modules for each chuck assembly to perform tests with different parameter requirements. Thus, different models of inductors can be connected to different chuck assemblies through terminals to achieve the corresponding parameter tests. This design not only simplifies the operator's work and reduces the possibility of human error, but also improves the accuracy and consistency of the test.
[0022] 3. In this utility model, each clamp assembly includes a positioning structure and a clamping structure. The clamping structure is movably positioned above the positioning structure and has a first moving position and a second moving position. When the clamping structure moves to the first moving position, the clamp assembly can be closed. When the clamping structure moves to the second moving position, the clamp assembly can be opened. When the clamp assembly is closed, the terminal can be clamped between the positioning structure and the clamping structure, that is, the positioning structure and the clamping structure respectively abut against the terminal, thus forming a two-point contact design and realizing Kelvin testing. This not only significantly improves the accuracy of resistance measurement, but also enables the equipment to remain safe and stable during high-current testing. Attached Figure Description

[0032] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0033] like Figures 1 to 4 As shown, in this embodiment, an inductor combination test device is used for testing inductors, the inductors having terminals (not shown in the figure), and the test device includes:
[0034] Workbench 100;
[0035] The testing component includes multiple testing instruments 200 mounted on a workbench 100 for testing different parameters;
[0036] A clamping mechanism, comprising a plurality of chuck assemblies 400 that are openable and closable on a worktable 100;
[0037] The control system is electrically connected to multiple testers and clamp assemblies, and is equipped with multiple preset test modules (not shown in the figure). When the control system detects that a terminal is on one or more clamp assemblies 400, it calls the preset test modules, which trigger multiple testers 200 to test the inductor and record the test data. This design integrates multiple testers 200 onto a workbench 100 and utilizes the control system and preset test modules to achieve automated one-time testing of different parameters of the inductor. Operators only need to connect the terminals to the clamping mechanism; all subsequent testing steps are completed automatically by the equipment. This not only significantly shortens testing time and improves work efficiency but also ensures the accuracy of test results. Furthermore, the design of multiple clamp assemblies 400 and multiple preset test modules allows the control system to configure different parameter requirements for each clamp assembly 400. This allows different models of inductors to be tested for corresponding parameters simply by connecting terminals to different clamp assemblies 400. Compared to the traditional single-clamp design, this design not only simplifies the operator's work and reduces the possibility of human error but also improves the accuracy and consistency of testing.
[0038] Specifically, such as Figures 1 to 4 As shown, in this embodiment, the workbench 100 is L-shaped and has a hollow structure, serving as an operating platform for inductor testing and supporting various components.
[0039] In this embodiment, the testing assembly includes multiple testers 200 mounted on a workbench 100 for testing different parameters. Each tester 200 includes a comprehensive tester, an interlayer impedance tester, a high-voltage tester, a superimposed inductance tester, and a DC bias tester, all electrically connected to a preset test module. The comprehensive tester comprehensively evaluates the overall performance of the inductor, including but not limited to key parameters such as inductance, quality factor (Q), and self-resonant frequency (SRF). The interlayer impedance tester is specifically used to measure the insulation resistance between the coils inside the inductor to ensure there are no short circuits or leakage between layers. The high-voltage tester tests the inductor's withstand voltage under high-voltage conditions, simulating high-voltage impact conditions in actual working environments. The superimposed inductance tester measures the inductance change when a DC bias current is applied. The DC bias tester tests the performance changes of the inductor when a large current is applied, particularly its inductance and saturation characteristics.
[0040] Furthermore, the preset test module, as part of the control system, is responsible for coordinating the working sequence of each tester 200 and the preset test parameter values. Once the terminals are connected to the clamping mechanism, the control system, according to the preset test procedure and parameters, calls the corresponding preset test module to sequentially or alternately trigger different testers 200, completing the automated testing and data recording of various inductor parameters. After one tester 200 completes its test, the preset test module automatically triggers the next tester 200, ensuring that all tests are completed in a single operation, thereby significantly shortening testing time and improving work efficiency.
[0041] In this embodiment, the integrated tester, interlayer impedance tester, high voltage tester, and superimposed inductance tester are detachably mounted above the workbench 100, and the DC bias tester is detachably mounted below the workbench 100.
[0042] In this embodiment, the control system includes an industrial control computer 300 mounted on the workbench 100 and equipped with a built-in control program, and a preset test module. The preset test module is electrically connected to a comprehensive tester, an interlayer impedance tester, a high-voltage tester, a superimposed inductance tester, and a DC bias tester, respectively. Under the control program, it sequentially or alternately triggers different testers 200 to complete the automated testing of various parameters of the inductor. This automated design not only improves testing efficiency but also reduces the possibility of human intervention, ensuring the accuracy and consistency of the test results.
[0043] It should be noted that when the terminals are clamped onto the clamp assembly 400, the control system can automatically identify the type of the clamp assembly 400 and call the corresponding preset test module to perform the appropriate test parameters and procedures. This design not only simplifies the operator's work and improves the accuracy and consistency of testing, but also makes the equipment applicable to the testing of different types of inductors, effectively improving the equipment's adaptability. Specifically, the test procedures and parameter requirements within each preset test module are different. When the operator clamps the inductor's terminals onto any one or more clamp assemblies 400, the control system calls the corresponding preset test module. For example, when the inductor's terminals are clamped onto the first clamp assembly 400, the control system calls the first preset test module; when the inductor's terminals are clamped onto the second clamp assembly 400, the control system calls the second or third preset test module. Thus, when dealing with inductors of different specifications or types, it is only necessary to clamp the inductor's terminals onto the designated clamp assembly 400.
[0044] In this embodiment, the clamping mechanism is located below multiple testers 200 and an industrial control computer 300. It includes multiple clamp assemblies 400 electrically connected to preset test modules. These clamp assemblies 400 are independent of each other, arranged in a line, and divided into two groups. Each group of clamp assemblies 400 corresponds to a test station, enabling dual-station alternating testing. This design ensures a compact and reasonable overall layout of the equipment, while also allowing operators to quickly and conveniently connect inductors to designated positions. Furthermore, the dual-station design allows for simultaneous testing at one station while the other station prepares for the next inductor under test, achieving seamless connection of the testing process. This avoids frequent downtime and waiting in traditional single-station testing, significantly improving testing cycle time and efficiency.
[0045] In this embodiment, each chuck assembly 400 not only possesses basic mechanical clamping functions but also has different parameter requirements configured through preset test module settings. This design allows each chuck assembly 400 to automatically adjust test conditions according to the specific inductor type and test requirements, enabling operators to test different types of inductors simply by connecting them to different chuck assemblies 400. This customized design allows the equipment to flexibly handle the testing needs of various types of inductors without requiring separate test conditions for each inductor, greatly improving testing convenience.
[0046] In this embodiment, each clamp assembly 400 includes a positioning structure 410 and a clamping structure 420. The top of the positioning structure 410 has a terminal placement position. The clamping structure 420 is movably disposed above the positioning structure 410 and has a first moving position and a second moving position. When the clamping structure 420 moves to the first moving position, the clamp assembly 400 is closed; when the clamping structure 420 moves to the second moving position, the clamp assembly 400 is open. When the terminal is on the positioning structure 410 and the clamping structure 420 moves to the first moving position, the positioning structure 410 and the clamping structure 420 respectively abut against the terminal. This design, through the coordinated work of the positioning structure 410 and the clamping structure 420, ensures that the terminal can be firmly and stably clamped during the test, thereby effectively guaranteeing the accuracy and reliability of the test. Furthermore, the positioning structure 410 and the clamping structure 420 abut against the terminals respectively, forming a two-point contact design. This design mimics the principle of the Kelvin test (four-wire method), separating the current application point and the voltage measurement point, eliminating the influence of lead resistance and contact resistance on the measurement results, and significantly improving the accuracy of resistance measurement. At the same time, this design also enables the equipment to remain safe and stable during high-current testing.
[0047] Preferably, in this embodiment, both the positioning structure 410 and the clamping structure 420 are gold-plated copper blocks, and both are vertically arranged and on the same straight line. The positioning structure 410 has a groove 411 at its top to ensure that the lead wire can be stably embedded, and the clamping structure 420 can move up and down in the vertical direction to clamp the terminal. This design effectively simplifies the process of fixing the terminal and improves the convenience of operation.
[0048] In this embodiment, the clamping mechanism includes a first mounting base 500 horizontally disposed on the worktable 100, which is responsible for supporting and fixing multiple positioning structures 410. The first mounting base 500 has multiple rectangular first mounting slots 501 arranged in a straight line. The positioning structures 410 are detachably fixed within the first mounting slots 501 by bolts; specifically, the positioning structures 410 are embedded within the first mounting slots 501. This design not only improves the ease of disassembly, assembly, and maintenance of the positioning structures 410, but also enhances the versatility and flexibility of the equipment.
[0049] In this embodiment, the clamping mechanism further includes a sensor 600 electrically connected to the control system, which is disposed on the clamp assembly 400. When the sensor 600 detects that a terminal is on the clamp assembly 400, the sensor 600 sends an electrical signal to the control system. The control system then drives the clamp assembly 400 to close and invokes a preset test module after the clamp assembly 400 closes. The sensor 600 serves not only as a trigger condition for the opening and closing of the clamp assembly 400 but also as a trigger condition for invoking the preset test module.
[0050] In this embodiment, the first mounting base 500 is further provided with a plurality of second mounting slots 502 communicating with the first mounting slot 501, and the sensor 600 is disposed in the second mounting slot 502. When the terminal is in the terminal placement position, the sensor 600 sends an electrical signal to the control system, and after receiving the electrical signal, the control system drives the clamping structure 420 to move to the first moving position, and after the terminal is clamped between the positioning structure 410 and the clamping structure 420, the corresponding preset test module is invoked. By introducing the sensor 600 electrically connected to the control system, the sensor 600 can detect whether the terminal is placed in the correct terminal placement position and can trigger the clamping action, and at the same time trigger the control system to invoke the corresponding preset test module. On the basis of realizing automatic terminal identification and clamping, manual intervention is reduced and the testing efficiency is improved.
[0051] Preferably, the second mounting groove 502 is T-shaped, perpendicular to and connected to the end of the first mounting groove 501, and the sensor 600 is detachably disposed in the middle position of the second mounting groove 502, so that the extension line of the sensor 600 intersects with the terminal placement position, ensuring that the inductor can accurately detect the position of the terminal.
[0052] In this embodiment, the sensor 600 is a proximity switch, a position switch, a photoelectric sensor, or a pressure sensor. Preferably, the sensor 600 is a proximity switch.
[0053] In this embodiment, a long strip-shaped protective plate 503 is detachably provided on the first mounting base 500. The protective plate 503 extends along the length of the first mounting base 500 and has multiple rectangular placement holes 504 that correspond one-to-one with and communicate with the second mounting groove 502. The protective plate 503 can partially shield the clamping structure 420 and the positioning structure 410. The protective plate 503 forms a physical barrier, allowing the terminals to only extend between the positioning structure 410 and the clamping structure 420 through the placement holes 504. This effectively prevents operators from accidentally contacting high voltage or moving parts, greatly improving the safety of equipment use.
[0054] In this embodiment, the clamping mechanism further includes a second mounting base 510 disposed above the first mounting base 500. The second mounting base 510 has multiple sets of drive structures 700 corresponding one-to-one with the clamping structure 420. Each drive structure 700 is electrically connected to the control system, and the clamping structure 420 is detachably disposed at the output end of the drive structure 700. This design allows the drive structure 700 to drive the clamping structure 420 between a first moving position and a second moving position under the control of the control system. Specifically, when the control system receives a signal from the sensor 600, it can drive the clamping structure 420 to the first moving position to clamp the terminal; when the test is completed and the test result is qualified, the control system can drive the clamping structure 420 to the second moving position to release the terminal. This design achieves automatic clamping and releasing of the inductor terminals, reducing the possibility of manual intervention and improving testing efficiency. Furthermore, the detachable design of the clamping structure 420 not only simplifies equipment maintenance and debugging but also enhances the equipment's versatility and flexibility.
[0055] In this embodiment, the drive structure 700 is a drive cylinder, a hydraulic cylinder, or a drive motor. Preferably, the drive structure 700 is a drive cylinder.
[0056] Preferably, in this embodiment, the workbench 100 is also equipped with a reset button 110 electrically connected to the control system. When the test is completed and the test result is unqualified, the operator presses the reset button 110, and the system can drive the clamping structure 420 to move to the second moving position to release the terminal. This design allows the operator to quickly release the terminal simply by pressing the reset button 110, reducing the time and complexity of manual operation and improving testing efficiency. Furthermore, a foolproof mechanism is introduced to ensure that the operator can only release the terminal using the reset button 110 after the test is completed and the test result is unqualified. This effectively avoids the situation where the operator removes the inductor prematurely during the test, preventing incomplete or incorrect test data due to misoperation and improving the reliability of inductor quality control.
[0057] In this embodiment, a workpiece placement mechanism is also included, comprising a workpiece placement plate 800 and a scissor-type lifting platform 900. The workpiece placement plate 800 is movably mounted on the worktable 100 and located in front of the chuck assembly 400, for placing the inductor under test. The scissor-type lifting platform 900 is located below the workpiece placement plate 800 and can drive the workpiece placement plate 800 to move closer to or further away from the chuck assembly 400. This design makes the overall layout of the equipment more compact and allows the workpiece placement plate 800 to be adjusted at different heights to accommodate inductors of different types and sizes, effectively improving the adaptability and flexibility of the equipment.
[0058] In this embodiment, the scissor-type lifting platform 900 includes a lifting plate 910 with multiple fixing holes 911 and at least two limiting members 920 detachably connected to the fixing holes 911. A workpiece placement plate 800 is detachably connected to the fixing holes 911 by bolts, and both ends of the workpiece placement plate 800 abut against at least two limiting members 920. This design allows operators to select workpiece placement plates 800 of different sizes according to the inductor's dimensions. Simultaneously, the cooperation between the limiting members 920 and the fixing holes 911 ensures the stability of the workpiece placement plate 800 during lifting and operation, avoiding test errors caused by shaking or tilting, and improving test reliability.
[0059] It should be noted that the scissor lift platform 900 is driven by a handwheel, and except for the design of the fixing hole 911 on the lifting plate 910 and the limiting member 920, the structure of the scissor lift platform 900 is consistent with the existing design. Therefore, other structures will not be described in detail here.
[0060] In this embodiment, both the scissor-type lifting platform 900 and the workpiece placement plate 800 are provided in two sets, corresponding one to one. The workbench 100 also has a transfer placement plate 810 arranged adjacent to the two sets of workpiece placement plates 800. The transfer placement plate 810 extends along the arrangement direction of the two sets of workpiece placement plates 800, and both the transfer placement plate 810 and the workpiece placement plate 800 are insulating boards. This design, in conjunction with the two sets of clamp assemblies 400, enables dual-station alternating testing. That is, while testing is being performed at one station, the other station can prepare the next inductor to be tested, significantly improving the testing cycle time and efficiency. The transfer placement plate 810 provides a temporary storage area for the inductors, and the use of insulating materials avoids mutual interference between inductors, ensuring a clean and safe testing environment.
