Abstract
Description
Technical Field
[0001] This utility model relates to the field of inductor surface defect detection technology, specifically to an inductor surface defect detection device. Background Technology
[0002] An inductor is an electronic component that stores energy and is widely used in power management, signal processing, and other fields. Any defects in the manufacturing process can lead to a decrease in inductor performance or even complete failure. Therefore, effective defect detection is crucial. Inductor defect detection refers to a series of tests and inspections performed on inductors during the production process or before the product is used to ensure that it meets design specifications and can function properly.
[0003] Based on the above, the inventors have discovered the following problems: the detection of surface defects in inductors currently mainly relies on manual visual inspection and traditional optical inspection equipment. Although manual inspection is intuitive, it is affected by factors such as the subjective judgment of the inspector, fatigue, and differences in viewing angle, which can easily lead to missed detections or misjudgments. Traditional optical inspection systems usually use fixed light sources, and when faced with complex backgrounds or uneven lighting production environments, the detection effect often fails to meet the requirements of high accuracy and high efficiency for high-speed production lines.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an inductor surface defect detection device in order to achieve a more practical purpose. Utility Model Content

[0034] Please see Figures 1-5 This utility model provides a technical solution: an inductor surface defect detection device, including a mounting assembly 1. The mounting assembly 1 includes a base plate 11, side plates 12 fixedly mounted on both sides of the base plate 11, and a top plate 13 fixedly mounted on the top of the side plates 12. The side plates 12 and the top plate 13 are designed to reduce the interference of external ambient light on the detection process, thereby improving the image quality acquired by the camera assembly 3. A rotating assembly 4 is fixedly mounted at the top center of the base plate 11. The rotating assembly 4 facilitates the transport of the inductor to be tested to the detection station for surface defect detection. A mounting hole 16 is provided on one side of the top plate 13. Two universal joint assemblies 2 are fixedly mounted inside the mounting hole 16. The two universal joint assemblies 2 facilitate the fixed mounting of two symmetrically arranged camera assemblies 3 on the top of the rotating assembly 4, and allow adjustment of the angle and orientation of the camera assemblies 3, which helps to improve detection accuracy and avoid blind spots from a single camera 31.

[0035] The rotating assembly 4 includes a rotating base 41, a glass turntable 42 fixedly mounted on the output end of the rotating base 41, and a positioning fixture fixedly mounted on the top of the glass turntable 42.

[0036] The side panel 12 is made of double-layer laminated tempered glass, and the space between the layers of the side panel 12 is filled with a light-guiding film. The fact that the side panel 12 is made of double-layer laminated tempered glass helps to improve the structural strength and optimize the optical performance, thereby reducing the interference of external ambient light on the detection.
[0037] The universal joint assembly 2 includes a mounting flange 21, which is located at the top of the mounting hole 16. The mounting flange 21 facilitates the fixed connection between the universal joint assembly 2 and the top plate 13.

The light source adjustment knob 19 allows for adjustment of the illumination intensity of the ring light 32.
[0042] Among them, a mounting plate 14 is fixedly installed on the outer side of the bottom end of the side plate 12. The surface of the mounting plate 14 has through holes. The mounting plate 14 makes it easy to fix the device in a suitable position in production and facilitates the detection of surface defects of the inductor.
[0043] Specifically, the working principle of this inductor surface defect detection device is as follows: During use, the mounting plate 14 facilitates the fixed installation of the device at a suitable production location, enabling convenient surface defect detection of the inductor. The mounting screws 27 ensure a secure fixation of the universal joint assembly 2 inside the mounting hole 16. The side plates 12 and top plate 13 reduce interference from ambient light during the detection process, improving the image quality acquired by the camera assembly 3. The side plates 12, being double-layered laminated tempered glass, enhance structural strength and optimize optical performance, further reducing interference from external ambient light. The ambient light interferes with the detection. A ball seat 23 is rotatably connected inside the ball sleeve 22, allowing the ball sleeve 22 to limit the movement of the ball seat 23, enabling it to rotate within the sleeve 22. The mounting base 24 facilitates the adjustment of the camera component 3's orientation by rotating the ball seat 23. The adjustment handle 25 allows for convenient adjustment of the camera component 3's orientation by rotating it outside the mounting component 1. The rotating base 41 and glass turntable 42 facilitate the rotation of the glass turntable 42, transporting the inductor to be tested to the detection station. The device allows for surface defect detection, and the camera assembly 3 at the bottom of the rotating assembly 4 can easily detect surface defects on the bottom of the inductor. The data interface 17, power interface 18, and light source adjustment knob 19 facilitate connection to external wiring for power supply and transmission of image data. The light source adjustment knob 19 allows for adjustment of the illumination intensity of the ring light 32. The two universal joint assemblies 2 facilitate the fixed installation of two symmetrically arranged camera assemblies 3 on the top of the rotating assembly 4, and allow for adjustment of the angle and orientation of the camera assemblies 3. This design helps improve detection accuracy and avoids false or missed detections caused by blind spots in the single-camera view. The ring light 32 emits light in the same direction as the camera 31, which facilitates uniform illumination of the detection station and avoids detection errors caused by uneven light distribution in traditional detection devices. The control panel 15 facilitates power supply and control of the camera assembly 3 and allows for electrical connection of the device to external equipment, enabling integration into the production line. This allows for real-time location and classification of inductor defects and feedback of the results to the production line control system, facilitating the screening out of defective inductors.
