Description

Technical Field

[0001] The utility model relates to the field of inductance components, in particular to an inductance component testing device. Background Art

[0002] As a crucial component of electronic equipment, the performance and reliability of inductors directly impact the overall system's performance. Therefore, comprehensive and accurate testing of inductors is crucial. However, existing inductor component testing equipment still has some issues and limitations in practical applications.

[0003] Traditional inductor component testing equipment typically utilizes simple test platforms that lack effective heat dissipation mechanisms. Heat accumulation is a particularly prominent issue during testing, especially for high-power inductors. Excessive temperatures not only affect the accuracy of test results but can also degrade or even damage the components under test. While some test equipment is equipped with simple cooling devices like fans, these are often less than ideal and cannot meet the demands of long-term, high-intensity testing. Consequently, it is impossible to accurately determine the heat dissipation configuration actually used for the inductor under test before installation.

[0004] Furthermore, existing test equipment has shortcomings when it comes to component replacement and positioning. Many devices use fixed fixtures or simple manual adjustment mechanisms, making the replacement and positioning of inductors of varying specifications cumbersome and time-consuming, severely impacting test efficiency. This inefficient operation not only increases the potential for human error but also limits the implementation of batch testing.

[0005] When it comes to test data collection, existing technologies are mostly limited to measuring electrical parameters, lacking effective monitoring of component temperature changes during actual operation. This neglect can lead to failure to detect potential overheating issues in a timely manner, increasing safety risks during testing.

[0006] Another common problem is the limited applicability of test equipment. Many devices are designed only for specific inductor component types or sizes, lacking the flexibility to adapt to the testing needs of products with varying specifications. This limitation not only increases equipment investment costs but also hinders rapid iteration and innovation in R&D and production processes.

[0007] In general, existing inductor component testing equipment still has significant room for improvement in terms of heat dissipation, operational efficiency, temperature monitoring, and applicability. Developing new test equipment that can effectively address these issues is crucial for improving the accuracy, efficiency, and safety of inductor component testing, as well as promoting technological advancement in related industries.

[0008] Therefore, it is urgent to invent an inductor component testing device to effectively solve at least one of the above technical problems. Utility Model Content

[0009] The purpose of the utility model is to provide an inductor component testing device, aiming to solve the technical problems of poor heat dissipation effect and low testing efficiency in the existing inductor component testing process.

[0010] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The cooling device is connected to the heat dissipation structure. The fixture system is movably disposed on the first surface of the test board.

[0012] Furthermore, the heat dissipation structure includes evenly arranged heat dissipation fins.

[0013] Specifically, the cooling device is a fan.

[0014] Furthermore, the testing device further includes a water cooling system, which is arranged between the testing board and the heat dissipation structure.

[0015] Specifically, the water cooling system is a water cooling pipe with a multi-bending structure.

[0016] Furthermore, the fixture system includes two first slide rails, at least two first sliders, and a bracket. The first slide rails are disposed on both sides of the test plate. The first sliders are slidable on the first slide rails. The bracket is connected to the first sliders.

[0017] Furthermore, the clamp system further includes a second slide rail and a second slider, wherein the second slide rail is disposed on the bracket, and the second slider can slide on the second slide rail.

[0018] Specifically, both the first sliding block and the second sliding block are provided with a lubrication structure.

[0019] Furthermore, the fixture system further includes a carrier and a fixing structure. The carrier is connected to the second slider. The fixing structure is provided on the carrier and is used to fix the inductor component.

[0020] Furthermore, the test equipment further comprises a temperature sensing system, which is connected to the inductive component to be tested and is used to measure the temperature of the inductive component to be tested.

[0021] The inductor component testing equipment provided by the present invention has the following beneficial effects: by providing a heat dissipation structure and a cooling device on the test board, the heat dissipation effect during the test process is significantly improved, effectively preventing the performance degradation or damage of the inductor component due to excessive temperature during the test process, and also being able to know the heat dissipation requirements of the inductor component in actual work in this way; at the same time, the movable fixture system design greatly improves the replacement and testing efficiency of the inductor component, making the testing process faster and more convenient.

[0022] Furthermore, the addition of a water cooling system further enhances heat dissipation, making it particularly suitable for testing high-power inductors.

[0032] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0033] like Figure 1-3 As shown, the inductor component testing equipment provided by the present invention includes a testing board 1, a heat dissipation structure, a cooling device and a fixture system 4.

[0034] The test board 1 has a first surface for placing inductive components and an opposing second surface. Preferably, the test board 1 is made of a metal material with good thermal conductivity, such as an aluminum alloy or copper alloy, and can be 10-20 mm thick. The dimensions of the test board 1 can be designed according to actual needs, for example, 500 mm x 400 mm. The design of the test board 1 is to provide a stable platform for placing inductive components and to serve as a foundation for heat dissipation.

[0035] The heat dissipation structure is arranged on the second side of the test board 1. In this embodiment, the heat dissipation structure includes uniformly arranged heat dissipation fins 2. The number, size and spacing of the heat dissipation fins 2 can be optimized according to the heat dissipation requirements. For example, 50-100 heat dissipation fins 2 can be set, each fin has a height of 30-50 mm, a thickness of 2-5 mm, and a spacing of 5-10 mm. The heat dissipation fins 2 can be connected to the test board 1 by welding, screw fixing or integral molding. The specific connection method belongs to the conventional means of those skilled in the art and will not be repeated here. The design purpose of the heat dissipation structure is to increase the heat dissipation area and improve the heat dissipation efficiency.

[0036] The cooling device is connected to the heat dissipation structure. In this embodiment, the cooling device can be a fan 3. The fan 3 is fixedly arranged at one end of the heat dissipation fin 2. The model and power of the fan 3 can be selected according to the heat dissipation requirements. For example, an axial flow fan with a diameter of 120 mm and a rotation speed of 1000-3000 RPM can be selected. The fan 3 can be fixed to the test board 1 and / or the heat dissipation fin 2 by means of screws or clips. The specific fixing method belongs to the conventional means of those skilled in the art and will not be repeated here. The design purpose of the cooling device is to accelerate heat dissipation and further improve the heat dissipation effect.

[0037] The fixture system 4 is movably arranged on the first surface of the test plate 1. Figure 4-6 As shown, the clamping system 4 includes two first slide rails 40 , at least two first sliders 41 , a bracket 42 , a second slide rail 43 , a second slider 44 , a platform 47 and a fixing structure 48 .

[0038] Two first rails 40 are provided on either side of the test plate 1. The first rails 40 are fixed to the test plate 1 with screws, with the screw spacing being 50-100 mm. The length of the first rails 40 can match the length of the test plate 1, and the material can be selected from a wear-resistant alloy steel.

[0039] At least two first sliding blocks 41 can slide on the first slide rail 40. The first sliding blocks 41 can be high-precision linear sliding blocks, and the material can be high-strength engineering plastics or alloy steel.

[0040] Bracket 42 is connected to first slider 41. Bracket 42 can be made of aluminum alloy and have an I-shaped or rectangular cross-section to improve strength and rigidity. The length of bracket 42 can be designed based on the width of test plate 1, for example, 50-100 mm longer than the width of test plate 1.

[0041] The second slide rail 43 is provided on the bracket 42. The second slide rail 43 can be fixed on the bracket 42 by screws or buckles, and its length can match the length of the bracket 42.

[0042] The second slider 44 can slide on the second slide rail 43. The design of the second slider 44 can be similar to that of the first slider 41, but the size can be adjusted according to actual needs.

[0043] Both the first and second sliders 41 and 44 are equipped with a lubrication structure 45. This lubrication structure 45 can be a lubricating oil inlet, designed as a small hole with a diameter of 2-5 mm, which facilitates the injection of lubricating oil and extends the service life of the sliders. Furthermore, fixing holes 46 can be provided on the top surfaces of both the first and second sliders 41 and 44. These fixing holes 46 can be designed as M6-M8 threaded holes for securing other components.

[0044] The carrier 47 is connected to the second slider 44. The carrier 47 can be fixed to the second slider 44 by screws, and can be made of aluminum alloy. A plurality of mounting holes can be designed thereon to accommodate inductance components of different sizes.

[0045] A fixing structure 48 is provided on the carrier 47 to secure the inductor component. In this embodiment, the fixing structure 48 may be a fixing pin, which is disposed in a hole defined at the end of the carrier 47 distal from the second slider 44. The fixing pin may be made of wear-resistant alloy steel, have a diameter of 3-8 mm, and be designed in length based on the size of the inductor component.

[0046] The fixture system 4 is designed to achieve precise positioning and rapid replacement of inductor components, thereby improving test efficiency and flexibility.

[0047] Furthermore, if Figure 2 As shown, the test equipment also includes a water cooling system 5, and the water cooling system 5 is arranged between the test board 1 and the heat dissipation structure 2. In this embodiment, the water cooling system 5 can be a water cooling tube with a multiple-bend structure. The water cooling tube can adopt a copper tube with good thermal conductivity, the inner diameter can be 6-10mm, and the wall thickness can be 0.5-1mm. The water cooling tube adopts a multiple-bend structure, which can maximize the use of the area of the test board 1 and improve the heat dissipation efficiency. The water cooling tube can be in close contact with the test board 1 by welding or pressing in. The specific connection method belongs to the common means of those skilled in the art and will not be repeated here. The design purpose of the water cooling system 5 is to further enhance the heat dissipation effect, and it is particularly suitable for testing high-power inductive components.

[0048] In addition, the present invention also includes a temperature sensing system (not shown in the figure). The temperature sensing system is connected to the inductive component to be tested and is used to measure the temperature of the inductive component to be tested. The temperature sensing system can use common temperature sensors such as thermocouples or thermistors, with a measurement range of -50°C to 200°C and an accuracy of up to ±0.5°C. The temperature sensor can be connected to the data acquisition system via a wire to monitor and record the temperature changes of the inductive component in real time. The temperature sensing system is designed to monitor the temperature of the inductive component in real time to ensure the safety and reliability of the testing process.

[0049] The working process of the inductor component testing equipment of the present utility model is as follows:

[0050] First, the operator places the inductor component under test on the first side of test board 1. By adjusting the position of fixture system 4, carrier 47 is moved to the appropriate position, and then the inductor component is secured using fixing structures 48 (such as fixing pins). This process can be completed quickly, improving test efficiency.

[0051] Next, connect the temperature sensing system's sensor to the inductor component. This step is crucial for real-time monitoring of the inductor's temperature to prevent damage due to overheating.

[0052] Next, the cooling device (e.g., fan 3) and water cooling system 5 are activated. Fan 3 begins operating, forcing air through the heat dissipation structure (e.g., heat sink fins 2), accelerating heat dissipation. Simultaneously, the coolant in water cooling system 5 begins circulating, further enhancing heat dissipation. This multi-layered heat dissipation design effectively prevents performance degradation or damage to inductor components caused by overheating during testing.

[0053] Testing of the inductor components begins. During testing, the heat dissipation structure, cooling device, and water cooling system 5 work together to effectively dissipate the heat generated by the inductor components. Simultaneously, the temperature sensing system monitors the temperature changes of the inductor components in real time. This data can be recorded and analyzed to evaluate the performance and reliability of the inductor components.

[0054] After the test is completed, the operator can quickly adjust the position of the fixture system 4 and replace the next inductor component to be tested. The multi-directional movable slide rail and slider structure makes this process simple and efficient, greatly improving test efficiency.

[0055] The entire test process can be repeated multiple times as needed, which is suitable for batch testing or long-term continuous testing scenarios.

[0056] The inductor component testing equipment provided by the utility model has the following beneficial effects:

[0057] The combined heat dissipation design of a heat sink structure, cooling device, and water cooling system on the test board significantly improves heat dissipation during testing. This multi-layered heat dissipation design effectively prevents performance degradation or damage to inductor components caused by overheating during testing, making it particularly suitable for testing high-power inductors. This improved heat dissipation not only ensures the accuracy of test results but also extends the service life of inductors, reducing damage and replacement costs caused by overheating.

[0058] The removable fixture system significantly improves the efficiency of replacing and testing inductor components. The multi-directionally movable rails and sliders make the test process more flexible and precise, accommodating inductors of varying sizes and shapes and enhancing the versatility of the test equipment. This design not only saves time but also reduces the potential for human error, improving test consistency and reliability.

[0059] The introduction of a temperature sensing system enables real-time monitoring of inductor component temperature changes during testing. This not only effectively ensures the accuracy of test results but also promptly identifies potential overheating issues, improving test safety. The collection and analysis of real-time temperature data also helps R&D personnel better understand the performance of inductors under different operating conditions, providing valuable data support for product optimization and improvement.

[0060] The overall design is simple and easy to maintain and operate. The modular design allows components to be replaced or upgraded based on actual needs, increasing the scalability and service life of the equipment. This design concept not only reduces maintenance costs but also allows the equipment to adapt to future testing requirements for new inductive components, extending its service life.

[0061] The combination of these features not only improves testing efficiency and accuracy, but also significantly expands the applicability and practicality of the test equipment, providing strong technical support for the R&D and quality control of inductive components. By using this test equipment, inductive component manufacturers can conduct product testing and quality control more quickly and accurately, thereby improving product quality, reducing production costs, and enhancing market competitiveness. Furthermore, this equipment provides a reliable testing platform for the R&D and innovation of inductive components.
