Description

Technical Field

[0001] This utility model relates to the field of coils, and specifically to an automatic coil detection device. Background Technology

[0002] A coil is typically a helical or ring-shaped structure made of wire. It is a common component in electronic devices, often found in inductors, transformers, motors, and other equipment. Coils play multiple important roles in circuits, such as energy storage, filtering, voltage transformation, and electromagnetic induction. For example, in an inductor, a coil can store magnetic field energy; in a transformer, a coil achieves voltage transformation through the principle of electromagnetic induction; and in a motor, a coil is a key component in generating a rotating magnetic field. An automatic coil testing device is a device specifically designed to automatically detect various parameters of a coil. These parameters may include the coil's resistance, inductance, and inter-turn insulation performance, which are crucial for ensuring the quality and performance of the coil. Automatic coil testing devices typically integrate multiple technologies such as mechanics, electronics, and optics to achieve comprehensive coil testing.

[0003] A search revealed an automatic coil detection device (CN216485458U). This device includes an upper housing, a lower housing, two sets of lead screws positioned between the upper and lower housings, and a mounting plate threaded to the lead screws via a threaded tube. Protective components are installed around the outer periphery of both sets of lead screws. A drive assembly for easy disassembly is installed within the lower housing, and this drive assembly meshes with the two sets of lead screws. The automatic coil detection device of this invention provides protective components around the lead screws. These components isolate the lead screws through upper and lower telescopic sleeves, preventing dust accumulation that could cause rotational jamming. Furthermore, the cooperation of a column and a slip ring limits the movement of the upper and lower telescopic sleeves, preventing friction and dust accumulation during rotation. The accumulation of dust could easily cause the lead screws to jam, further preventing this issue. The drive motor is plugged into the lower housing, facilitating its disassembly and assembly.

[0004] Existing automatic coil testing devices suffer from limitations due to their limited and incomplete testing methods. After testing, they may encounter defects in appearance and other parameters, resulting in low testing efficiency and reduced accuracy. Furthermore, the automatic coil testing devices in the comparative cases mentioned above also lack comprehensive testing capabilities. Consequently, long-term use cannot ensure that the coils meet quality requirements in multiple key parameters, necessitating extensive manual intervention and repetitive testing operations.

[0005] Therefore, it is necessary to invent an automatic coil detection device to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an automatic coil testing device. This device, through a testing platform, side clamping platform, coil test clamp, external wiring, optical inspection camera, lower testing frame, second telescopic cylinder, and testing head, achieves comprehensive testing capabilities. It allows for detailed inspection of the appearance of external coils, such as surface defects and dimensional deviations, and also enables comprehensive testing of the electrical performance of external coils, such as resistance, inductance, and inter-turn insulation, using the coil test clamp and probe. This combination of optical and electrical performance testing capabilities ensures that the coil meets quality requirements across multiple key parameters. Furthermore, the entire process is automated, improving testing efficiency and accuracy. The device is also applicable to testing various types of coils. This addresses the problem of existing automatic coil testing devices, which suffer from limited and incomplete testing methods, often encountering appearance and other parameter defects after testing. This leads to low testing efficiency and reduced accuracy. Additionally, the automatic coil testing devices in the aforementioned comparative case also lack comprehensive testing capabilities, making it impossible to ensure that coils meet quality requirements across multiple key parameters over long-term use, necessitating significant manual intervention and repetitive testing operations.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-6 The illustrated automatic coil detection device includes a detection machine base 1 and a main body for coil detection;

[0029] Angle disk 2 is rotatably connected to the top of the testing machine 1. A four-jaw center chuck 3 is fixedly installed on the top of the angle disk 2. A sliding groove 4 is opened inside the four-jaw center chuck 3. A sliding block 5 is slidably connected inside the sliding groove 4. A threaded rod 6 passes through the external thread of the sliding block 5. A center jaw 7 is fixedly installed on the top of the sliding block 5. An outer coil 8 is sleeved on the outside of the center jaw 7.

[0030] Side clamping platform 9 is fixedly installed on both sides above the testing machine 1 for externally fixed installation of coil test clamp 10, and external wiring 11 is fixedly connected to the side clamping platform 9. Movable frame 12 is fixedly installed above the testing machine 1, and support rod 13 is hinged above the movable frame 12. Optical inspection camera 14 is fixedly installed above the support rod 13.

[0031] The upper detection seat 17 is fixedly installed above the detection machine 1. An electric slide rail 18 is fixedly installed at the bottom of the upper detection seat 17, and an electric sliding sleeve 19 is slidably connected to the outside of the electric slide rail 18. A lower detection frame 20 is fixedly installed at the bottom of the electric sliding sleeve 19. A second telescopic cylinder 21 is fixedly installed on both sides of the bottom of the lower detection frame 20. A detection head 22 is fixedly installed at the bottom end of the second telescopic cylinder 21. The angle plate 2 drives the outer coil 8 fixed on the four-jaw center chuck 3 to rotate at a uniform speed through the internal motor. The optical detection camera 14 first detects the appearance of the outer coil 8. Then, the external wiring of the outer coil 8 is clamped and connected by the coil test clamps 10 on both sides. The performance of the outer coil 8 is tested by the detection machine 1. Then, the second telescopic cylinder 21 can drive the detection head 22 to descend, so that the probe on the detection head 22 can perform performance testing on the outer coil 8 from above. This three-in-one detection method gives the automatic coil detection device a comprehensive detection capability.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the central gripper 7 is slidably connected to the four-jaw central chuck 3, and the sliding block 5 is used in conjunction with the sliding groove 4. The central gripper 7 is used to support the outer coil 8 from the inside and fix the outer coil 8 for inspection. The optical inspection camera 14 is rotatably connected to the inspection machine 1. The coil test clamp 10 is symmetrically arranged with respect to the central axis of the inspection machine 1. The optical inspection camera 14 can be adjusted up and down to better complete the appearance inspection. A support plate 15 is fixedly installed on the back of the inspection machine 1. A first telescopic cylinder 16 is fixedly installed on the top of the support plate 15. The top of the first telescopic cylinder 16 is hinged to the bottom of the optical inspection camera 14. The extension and retraction of the first telescopic cylinder 16 is used to adjust the up and down angle of the optical inspection camera 14.

[0033] like Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, main probe rods 23 are fixedly installed on both sides of the bottom of the detection head 22. The detection head 24 is slidably connected inside the main probe rods 23. After the detection head 24 touches the outer coil 8, the detection head 24 will slide and extend inward into the main probe rod 23. The detection head 24 presses the buffer extension spring 26, thereby reducing the wear caused to the outer coil 8 by the descending detection head 24. An outer fixing plate 25 is fixedly installed on the outside of the detection head 24. The buffer extension spring 26 is sleeved on the outside of the detection head 24. The front end of the buffer extension spring 26 is fixedly connected to the outside of the outer fixing plate 25. The overall structure of the detection head 24 is simple and easy to operate. If a fault occurs, it is convenient for maintenance personnel to perform timely maintenance.

[0034] The working principle of this practical system is as follows: First, connect the external power supply, take out the outer coil 8 to be tested, place the outer coil 8 on the four-jaw center chuck 3, then twist the threaded rod 6 to adjust the position of the sliding block 5 in the sliding groove 4, and expand the center jaw 7 outward to support the outer coil 8 from the inside, thus fixing the outer coil 8 for testing. Next, the internal motor of the testing machine 1 drives the angle plate 2 to rotate the outer coil 8 fixed on the four-jaw center chuck 3 at a uniform speed, allowing the optical inspection camera 14 to inspect the appearance of the outer coil 8. At this time, the first telescopic cylinder 16 can be used to extend and retract to adjust the up and down angle of the optical inspection camera 14. Then, the external wiring of the outer coil 8 is clamped and connected by the coil test clamps 10 on both sides. The performance of the outer coil 8 is tested by the testing machine 1. Then, the switch of the electric slide rail 18 can be turned on, allowing the electric slide rail 18 to move the inspection head 22 above the outer coil 8. Then, the second telescopic cylinder 21 moves the inspection head 22 down, allowing the probe 24 on the inspection head 22 to inspect the performance of the outer coil 8 from above. After testing, the probe head 24 slides and extends inwards towards the main probe rod 23. The probe head 24 presses against the buffer spring 26, reducing the wear and tear on the outer coil 8 caused by the descending probe head 24. This three-in-one testing method gives the automatic coil testing device comprehensive testing capabilities. It allows for detailed inspection of the appearance of the outer coil 8, such as surface defects and dimensional deviations. It also performs comprehensive electrical performance testing on the outer coil 8 using the coil test clamp 10 and probes, including resistance, inductance, and inter-turn insulation. This combination of optical and electrical performance testing ensures that the coil meets quality requirements across multiple key parameters. After testing, the tested outer coil 8 is removed, and the next coil is replaced to continue the testing process. Finally, after completing the installation and use of the automatic coil testing device according to the above operations, the switches for the first telescopic cylinder 16, the electric slide rail 18, and the second telescopic cylinder 21 are turned off. If the device is not used for a long period, the external power supply should be disconnected. This completes the operation of the automatic coil testing device.
