[0002] After the ferrite magnetic core is produced, it needs to be magnetically tested. During the test process, the magnetic core needs to be wound with wire and then powered on. By testing data such as inductance value and impedance value, the quality of the ferrite magnetism is judged. However, when facing an annular ferrite magnetic core, the wire needs to pass through the central hole of the annular ferrite repeatedly, which is not convenient for using a machine to wind the coil. Therefore, manual winding is required. However, the winding and unwinding process of manual winding takes a lot of time. When the number of coils needs to be changed for repeated detection, it takes a long time, has a large operation difficulty, and the copper wire needs to be cut off each time for testing, resulting in waste of copper wire.

[0003] Therefore, there is an urgent need for a device that can quickly wind and detect an annular magnetic core, reduce the time used for winding, is convenient for disassembly, and does not cause waste of copper wire. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following will be combined with specific embodiments and attached Figures 1-4 , clearly and completely describe the technical solutions in the embodiments of the utility model.

[0018] A ring-shaped magnetic core winding device for detection includes a fixed frame 1, which includes a base 11, a slide bar 12 and a fixed plate 13. The base 11 is a rectangular structure. Four slide bars 12 are fixedly connected to the four corners of the top surface of the base 11. The four slide bars 12 are fixed upward. A fixed plate 13 is fixedly connected to the top of the four slide bars 12. A slide plate 2 is slidably connected to the slide bar 12. The slide bar 2 is also rectangular. Sliding holes are opened on the four corners of the slide bar 2. The slide bar 2 is simultaneously mounted on the four slide bars 12 through the sliding holes, so that the slide bar 2 can slide up and down along the slide bar 12 for adjustment.

[0019] Two winding shells 3 are arranged on the fixing frame 1, and the two winding shells 3 are symmetrically arranged up and down, one of which is fixedly connected to the top surface of the base 11, and the other is fixedly connected to the bottom surface of the slide plate 2. When the slide plate 2 slides along the slide rod 12, it can control the upper winding shell 3 to approach or move away from the other winding shell 3. The two winding shells 3 are arranged relatively, and the winding shells 3 are a cylindrical structure. One surface of the two winding shells 3 close to each other is its working surface, and a circular magnetic core groove 31 is opened on the working surface. The circular magnetic core groove 31 is used to place the detection magnetic core, and ten winding holes 32 are opened on the working surface of the winding shell 3, specifically located on the outer side of the circle where the magnetic core groove 31 is located. The winding hole 32 penetrates into the winding shell 3 from the center of the magnetic core groove 31, winds the magnetic core groove 31 180 degrees, and then passes through the inside of the circle where the magnetic core groove 31 is located. The ten winding holes 32 are intersected and overlapped at the center position of the circle where the magnetic core groove is located, forming a hole larger than the opening at the other end of the winding hole 32. The outlets are perpendicular to the working surface of the winding shell 3. Fifty-nine copper winding wires 4 are fixedly connected in the winding holes 32 of the two winding shells 3. The copper winding wires 4 are fixedly connected in the winding holes 32. The two ends of the copper winding wires 4 are fixedly connected with connecting terminals 41. The connecting terminals 41 are prior art. The two connecting terminals are close to each other and can be directly plugged in to achieve quick connection. The copper winding wires 4 on the two winding shells 3 are correspondingly arranged. When the two winding shells 3 are close to each other and fit together, the copper winding wires 4 in the two winding shells 3 are connected end to end using the connecting terminals 41. All the copper winding wires 41 are connected in series to form a spiral winding that is rotated around the magnetic core slot. The magnetic core is placed in the magnetic core slot 31 on the winding shell 3 fixed on the base 11, and then the slide plate 2 is slid toward the base 11 to make the two winding shells 3 contact. The copper winding wires 4 in the two winding shells 3 can be connected in series to form a complete winding. The process is simple, and there is no need to perform complicated winding operations, which can effectively increase work efficiency.

[0020] The device also includes an input wire 71 and an output wire 72 for connecting current during testing. The copper winding 41 in the winding housing 3 fixedly connected to the fixing bracket 1 is divided into a single-turn adjustable winding 42 and a multi-turn adjustable winding 43. The single-turn adjustable winding 42 includes nine copper windings 41, and the multi-turn adjustable winding 43 includes the remaining fifty copper windings 41. When the two winding housings 3 are close enough for the copper windings 41 in the two winding housings 3 to be connected to each other, the nine copper windings 41 in the single-turn adjustable winding 42 are adjacent, and they are connected in series with nine copper windings 41 in the other winding housing 3 to form a wire winding around the core slot 31 for nine turns. The nine copper windings 41 in the single-turn adjustable winding 42 are electrically connected to the input wire 71 through ten mutually exclusive switches 61 in the first switch group. The mutually exclusive switches 61 are prior art. The ten mutually exclusive switches 61 are connected in parallel with each other and only one of them can be connected at the same time. Similarly, the fifty copper windings 41 in the multi-turn adjustable winding 43 can also be connected in series with the copper windings in the other winding housing 3 to form a spiral wire wound for 50 turns. Six copper windings 41 at specific positions in the multi-turn adjustable winding 43 are electrically connected to the output wire 72 through six mutually exclusive switches 61 in the second switch group. Between any two adjacent mutually exclusive switches 61 in the six mutually exclusive switches 61 of the second switch group, there are ten copper windings 41, and these ten copper windings will be connected in series with ten copper windings 41 in the other winding housing 3 to form a spiral wire winding around the core slot for ten turns when the two winding housings 3 are close. The ten mutually exclusive switches 61 in the first switch group correspond to a1, b, c, d, e, f, g, h, i, j respectively, and the six mutually exclusive switches 61 in the second switch group correspond to a2, A, B, C, D, E respectively. Among them, the mutually exclusive switches corresponding to a1 and a2 are located at the connection between the single-turn adjustable winding 42 and the multi-turn adjustable winding 43. When the two winding housings 3 are close enough for all copper windings 41 to be connected in series, the joints of a1 and a2 are at the same position, which is the initial position. At this time, the current does not pass through the winding around the core slot 31, and the current flows from the input wire 71 through a1 and a2 directly to the output wire 72. Therefore, there is no current in the winding formed by connecting all copper windings 41 in series. When it is necessary to adjust the number of test turns to a single digit, the corresponding mutually exclusive switch 61 in the first switch group needs to be pressed. For example, if it is necessary to wind 5 turns currently, then f needs to be pressed. The current passes through the copper windings 4 between f and a2 in sequence from the input wire 71, and then is connected to the output wire 72 at a2 to obtain the desired number of winding turns. Similarly, each switch in the mutually exclusive switches of the second switch group corresponds to ten copper windings, so it corresponds to 10 turns of winding. By randomly combining the two switch groups, the number of winding turns can be adjusted arbitrarily between 1 and 59 for core testing, which can meet the requirements of different numbers of turns for testing. The mutually exclusive switches 61 in the first switch group and the second switch group are both integrated on a control panel 6 for adjusting the number of winding turns.

[0021] An indicator light 62 is also electrically connected between each mutually exclusive switch 61 and the copper winding 4, which can light up to indicate when the corresponding mutually exclusive switch 61 is in the connected state.

[0022] A through hole is provided at the top end of the fixed plate 13. At the same time, a stepping motor 5 is fixedly connected to the center position of the fixed plate 13, which is the position of the through hole. The stepping motor 5 is a through-type linear lead screw 51 stepping motor 5, and a lead screw 51 is equipped in its center. The stepping motor 5 can control the movement of the lead screw 51 along the axial direction of the lead screw 51. The lower end of the lead screw 51 is fixedly connected to the top surface of the sliding plate 2. By indirectly driving the upper winding shell 3 to move up and down through the stepping motor 5, the opening and closing of the two winding shells 3 can be controlled, which is convenient for taking and placing the magnetic core during the detection process and simplifies the operation process.
