Description

Technical Field

[0001] This utility model relates to the field of inductor performance testing technology, and in particular to an inductor performance testing device. Background Technology

[0002] Inductor performance testing is the process of inspecting and evaluating the electrical and physical characteristics of inductors. It aims to verify whether they meet design specifications, industry standards, and application requirements. The test focuses on key parameters such as inductance, DC resistance, quality factor, rated current and saturation current, distributed capacitance, insulation resistance, and temperature characteristics. Using professional equipment such as inductance testers and impedance analyzers, data is measured and analyzed under specific conditions to determine whether the inductor can work normally and reliably in the circuit. It is an important part of electronic component production, selection, and circuit design.

[0003] Currently, inductors are typically tested manually using a multimeter. This method is not only inefficient but also produces results with some error, making it impractical. Utility Model Content

[0006] A bracket is fixedly connected to the top of the base. A guide rod is fixedly connected to one side of the top of the bracket. A fixing plate is fixedly connected to the other end of the guide rod. A servo motor is fixedly installed on the outside of the fixing plate. A lead screw is fixedly connected to the output end of the servo motor via a coupling. A slider is movably connected to the outer wall of the lead screw and the guide rod. A cylinder is fixedly connected to the bottom of the slider. A lifting plate is fixedly connected to the output end of the cylinder. A test probe is provided at the bottom of the lifting plate to facilitate the forward and backward movement and lifting and lowering of the test probe, thereby facilitating the testing of the inductor.

[0007] According to the inductor performance testing device, the top of the slide table is provided with a clamping groove, and a bidirectional screw is rotatably connected inside the clamping groove. A guide rod is fixedly connected to the inner wall of the clamping groove, and two sliders are movably connected to the outer wall of the guide rod and the bidirectional screw. Each slider is fixedly connected to a clamping plate at its top, which facilitates the clamping of inductors of different sizes and improves the stability of the testing process.

[0008] According to the inductor performance testing device, a sensor is provided on one side of the bracket, and the servo motor one, servo motor two, test probe and sensor are all electrically connected to the controller to facilitate the transmission of electrical signals.

[0009] According to the aforementioned inductor performance testing device, a screw hole is provided at the center of the side of the slider one. The outer wall of the screw hole one and the outer wall of the lead screw one are both provided with threads. The screw hole one and the lead screw one are engaged with each other through the threads, which facilitates the left and right movement of the slider one, and thus facilitates the left and right movement of the inductor.

[0010] According to the inductor performance testing device, a screw hole is provided at the center of the side of the second slider. The inner wall of the screw hole and the outer wall of the lead screw are both provided with threads. The screw hole and the lead screw are engaged with each other through the threads, which facilitates the movement of the second slider and thus facilitates the adjustment of the front and rear positions of the test probe.

[0011] According to the aforementioned inductor performance testing device, the slider three has a screw hole three on its side. The inner wall of the screw hole three and the outer wall of the bidirectional screw are both provided with threads. The screw hole three and the bidirectional screw are engaged with each other through threads, which facilitates the clamping of the inductor.

[0012] According to the inductor performance testing device, the sides of slider one, slider two and slider three are respectively provided with guide hole one, guide hole two and guide hole three. Slider one, slider two and slider three are slidably connected to the outer walls of guide rod one, guide rod two and guide rod three through guide hole one, guide hole two and guide hole three, respectively, so as to facilitate the guidance and limiting of slider one, slider two and slider three.

One end of the lead screw, lead screw 1, and double-acting screw are respectively rotatably connected to the rotating shaft seat, which facilitates the rotation of lead screw 1, lead screw 2, and double-acting screw.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. This inductor performance testing device features a sliding groove on the top of the base. A servo motor drives a lead screw to rotate, which in turn drives a slider to reciprocate within the groove. This facilitates the left-right movement of the inductor on the top of the slide. Simultaneously, a servo motor drives a lead screw to rotate, which in turn drives the slider and test probe to move back and forth. A cylinder drives the test probe to rise and fall. A sensor detects the position of the inductor interface, and the relative movement between the inductor and the test probe allows the test probe to test the inductor interface at different positions on the slide, thus improving the efficiency of inductor performance testing.

[0016] 2. This inductor performance testing device has a clamping groove on the top of the slide table. A bidirectional screw is rotatably connected inside the clamping groove. By rotating the bidirectional screw, the relative movement of two sliders on its outer wall can be driven, which in turn can drive the movement of two clamping plates. Inductors of different sizes can be clamped by the two clamping plates to prevent them from shifting during the test and improve the stability of the test process.

[0035] Working principle: The inductor to be tested is placed at the top center of the slide table 10. The bidirectional screw 21 is rotated in the forward direction, which drives the relative movement of the two sliders 23 on its outer wall. This causes the two clamping plates 26 to clamp and limit the inductor, preventing it from shifting. After clamping, the test can begin. The position of the interface on the inductor is detected by the sensor 27. At the same time, the servo motor 3 drives the rotation of the lead screw 4, which in turn drives the movement of the slider 7 on its outer wall, facilitating the left and right movement of the slide table 10 and the inductor. The servo motor 13 drives the rotation of the lead screw 14, which in turn drives the slider 15 and the test probe 20 to move back and forth. At the same time, the cylinder 18 drives the lifting and lowering of the test probe 20. Through the relative movement of the inductor and the test probe 20, the test probe 20 can test the inductor interface at different positions on the slide table 10. After the test, the test probe 20 transmits the test data to the display screen of the controller 2 via an electrical signal.
