Abstract
Description
Technical Field
[0001] This utility model relates to the field of soft magnetic detection technology, and in particular to a convenient soft magnetic ring sample testing sample stage. Background Technology
[0002] In fields such as electronics, power, and communication equipment, soft magnetic rings, due to their excellent magnetic permeability, have become a key component of core components such as transformers and inductors. The accurate detection of their performance parameters, such as permeability and loss values, directly affects the operating efficiency and reliability of downstream equipment. These coils are typically wound with enameled wire, and the insulating varnish layer on the surface of the enameled wire is an important design feature to ensure detection stability. It effectively isolates the current conduction between coil turns, preventing short circuits and ensuring the uniformity of the excitation magnetic field and the purity of the induced signal. However, after the coil is wound, the four ends of the enameled wire (the two ends of the magnetizing coil and the two ends of the induction coil) need to be connected to the electrodes of the testing instrument. At this point, the insulating varnish layer becomes an "obstacle" to the electrical connection: if the insulating varnish at the wire ends is not removed, an insulating layer will form between the wire ends and the electrodes, hindering current input and signal output, making the detection circuit unable to conduct. Therefore, removing the varnish from the wire ends is an essential step before testing.
[0003] Currently, the most common method for removing enamel coating in the industry is manual scraping with a blade: the operator needs to hold a small, specialized enamel scraper or utility knife to treat the exposed parts of the wire ends. Since the diameter of commonly used enameled wires is mostly between 0.1-0.5mm, the wire is thin and has weak shear resistance, so the force applied during operation must be precisely controlled. Too much force will cut the enameled wire directly, while insufficient force will not completely remove the insulating enamel, leaving fine enamel residue. At the same time, the scraping area must be strictly controlled, removing only the small section of enamel layer used for wiring at the wire ends. If the enamel layer of the coil body is accidentally scraped, it will cause a short circuit between turns, rendering the coil unusable.
[0004] Based on the above-mentioned technical problems, this utility model provides a convenient soft magnetic ring sample testing stage. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] Reference Figures 1-3 This utility model provides a convenient soft magnetic ring sample testing sample stage, comprising:
[0029] The test box 1 has a detachable top cover 2. The top cover 2 has four sets of wire inlet holes 3 arranged in a rectangular structure. The enameled wire extends into the test box 1 through the wire inlet holes 3.
[0030] The chemical paint removal mechanism is located at the bottom of the test box 1. The chemical paint removal mechanism includes a solution circulation component and four sets of solution tanks 4. The four sets of solution tanks 4 are fixed at the bottom of the test box 1, and the four sets of solution tanks 4 are respectively set to correspond one-to-one with the four sets of inlet holes 3. All four sets of solution tanks 4 are connected to the solution circulation component.
[0031] The adjustable opening cleaning mechanism is provided in four sets, which are respectively arranged with four sets of inlet holes 3. The adjustable opening cleaning mechanism includes an expansion clamp, two sets of conductive springs 5 and a cleaning sponge 6, and a connecting piece is fixed at the top. The connecting piece is fixed to the bottom surface of the top cover 2. The two sets of conductive springs 5 are arranged opposite to each other. The cleaning sponge 6 is vertically fixed to the bottom of the conductive springs 5 by an insulating fixing plate.
[0032] The connecting piece extends out of the detection box 1 and connects to the electrodes of the power supply. The entire assembly is made of non-magnetic materials to avoid magnetic field interference from the outset.
[0033] In operation, the top cover 2 is first installed on the top of the detection box 1 via a detachable structure. The positions of the four rectangular inlet holes 3 are confirmed to be precise and correspond one-to-one with the four solution tanks 4 at the bottom of the detection box 1. The enameled wire to be tested is then passed through the four inlet holes 3, allowing the end of the wire to naturally extend into the detection box 1 and accurately fall into the corresponding solution tank 4, completing the initial positioning of the sample. The solution circulation component in the chemical paint removal mechanism is then activated. This component drives the paint removal solution to continuously circulate within the four solution tanks 4, ensuring uniform concentration of the paint removal solution in each tank 4 and accelerating the dissolution of the enamel film at the end of the wire through flow. After the end of the wire is immersed in the circulating solution for a certain period, the insulating enamel film on the surface is completely removed, providing pretreatment for subsequent conductivity testing. Four sets of adjustable-opening cleaning mechanisms operate synchronously: the opening is adjusted by the expansion clamps to match the diameter of the enameled wire to be tested. Simultaneously, the cleaning sponge 6, vertically fixed by the insulating fixing plate, tightly adheres to the surface of the enameled wire, physically wiping the wire after varnish removal to remove residual solution and varnish film debris, ensuring a clean wire surface. During this process, two sets of opposing conductive springs 5 maintain stable contact with the enameled wire, and the connecting piece on the bottom of the top cover 2 extends beyond the test box 1, reliably connecting to the power electrode, thus constructing the conductive circuit required for testing. After completing the above preparations, the testing process can be started. The conductive springs 5 stably transmit the power signal to the enameled wire, realizing the electrical performance testing of the soft magnetic ring sample. After the test, the top cover 2 is removed to take out the enameled wire sample. The solution circulation component stops working and the varnish removal solution is recovered, completing the entire process of a single test.
[0034] The scheme is further optimized. The circulation components include circulation pipes 7, circulation pumps and filters. The four sets of solution tanks 4 are connected to each other through circulation pipes 7. The circulation pump is connected to one of the sets of circulation pipes 7 through the main pipeline. The filter is installed on the main pipeline. The circulation pump is connected to the solution tank.
[0035] The design is further optimized. The expansion clamp includes a clamp head 8 and a clamp body 9. The clamp head 8 is fixed to the bottom of the clamp body 9 and is located inside the detection box 1. The clamp body 9 is slidably connected to the wiring hole. The clamp head 8 has a mushroom-shaped structure and is located between two sets of conductive springs 5. A through hole is opened at the center of the clamp body 9. The through hole passes through the clamp head 8 and the enameled wire passes through the through hole and extends into the detection box 1.
[0036] The expansion clamp consists of a mushroom-shaped clamp head and a clamp body that slides into the wire inlet hole. The enameled wire passes through the through holes in the clamp body and the clamp head and falls precisely into the corresponding solution tank. By sliding the clamp body up and down along the wire inlet hole, the clamp head can be moved. When sliding upward, the clamp head squeezes the conductive springs on both sides to expand it outward to fit the thicker enameled wire. When sliding downward, the clamp head moves away from the springs, and the springs elastically contract to fit the thinner enameled wire. At the same time, the clamp head helps to fix the position of the springs, ensuring stable contact pressure between the springs and the enameled wire, and realizing precise positioning and fitting of enameled wires of various specifications.
[0037] The design was further optimized so that the conductive spring 5 has a C-shaped structure and two sets of conductive springs 5 are arranged opposite each other.
[0038] The design was further optimized so that both the conductive spring 5 and the connecting piece are made of copper.
[0039] The design was further optimized so that the top cover 2 is fixed to the top of the detection box 1 by a snap fastener.
