[0002] A differential-mode inductor is an inductor primarily used for differential-mode signal filtering and power management. Its primary function is to suppress electromagnetic interference and noise while allowing differential-mode signals to pass through. A differential-mode signal refers to the relative variation of two signals at the same node and is commonly used in data communications and audio signal transmission. The production process for differential-mode inductors typically requires the use of a winding machine to wind the wire around a magnetic ring.

[0004] However, there is still room for improvement in the wire hooking mechanism of the aforementioned winding machine. For example, when the wire pulley of the wire guide mechanism guides the end of the copper wire above the magnetic ring, the wire is likely to hit other components during its upward movement due to its large swing range and amplitude, potentially damaging other components and ultimately the machine.

[0005] Therefore, there is a need to improve the existing technology. Utility Model Content

[0006] In response to the problems existing in the above-mentioned prior art, the purpose of the present utility model is to provide an improved magnetic winding machine hooking device, which can be used to limit the swing range and swing amplitude of the copper wire end to prevent the copper wire from damaging other components due to large swings during the process of being pulled upward, that is, it can protect the components.

[0007] In order to achieve the above purpose, the technical solution of the utility model is:

[0008] An improved wire hooking device for a magnetic winding machine comprises a frame, a limit box, a wire hooking mechanism and a wire diverting mechanism respectively located on the frame; a limit cavity with an upper end opening is provided inside the limit box; the wire hooking mechanism can be used to pull the end of the copper wire from the center of the magnetic ring located above it downward into the limit cavity; the wire diverting mechanism comprises a lever located outside the limit box and one end of which can extend leftward and rightward through a perforation on the limit box and extend into the limit cavity; and a wire diverting drive device fixed outside the limit box and used to drive the lever to swing back and forth; the lever is installed on the output end of the wire diverting drive device; the wire diverting drive device adopts a motor or a rotary cylinder.

[0026] The utility model will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely illustrative and does not limit the scope of protection of the utility model.

[0027] like Figures 1-6 As shown, an improved wire hooking device of a magnetic winding machine includes a frame 1 and a limit box 2, a wire hooking mechanism 3 and a wire diverting mechanism 4 respectively located on the frame 1.

[0028] A limiting cavity 21 with an open upper end is provided inside the limiting box 2; the wire hooking mechanism 3 can be used to pull the end of the copper wire downward from the center of the magnetic ring above it into the limiting cavity 21; the wire shifting mechanism 4 includes a shifting rod 41 located on the outside of the limiting box 2 and one end of which can extend left and right through the through-hole 22 on the limiting box 2 and extend into the limiting cavity 21, and a wire shifting drive device 42 fixed to the outside of the limiting box 2 and used for driving the shifting rod 41 to swing back and forth; the shifting rod 41 is installed on the output end of the wire shifting drive device 42; in the process of the end of the copper wire moving upward, the wire shifting drive device 42 can be used to drive the shifting rod 41 to shift the end of the copper wire to one side of the limiting cavity 21 to limit the swinging range of the copper wire, thereby preventing the copper wire from swinging too much and damaging other components.

[0029] It can be seen that the present invention utilizes the cooperation of the limit box 2 and the wire-dipping mechanism 4, so that after the end of the copper wire moves downward to the preset position, the wire-dipping drive device 42 will drive the dial rod 41 to move forward, that is, to move toward the front side wall of the limit cavity 21, thereby pushing the end of the copper wire to move in that direction, and then the dial rod 41 and the limit box 2 can be used to limit the swing amplitude and swing range of the copper wire, thereby preventing the copper wire from damaging other components due to the large swing during the process of being pulled upward, that is, the present invention can play the role of protecting components.

[0030] like Figure 1-Figure 5As shown, in the present embodiment, the wire driving device 42 adopts a motor 421 or a rotary cylinder 422, so that the lever 41 can be stably swung back and forth to move the copper wire. At this time, the shape of the perforation 22 is similar to the swing path of the lever 41, and is arc-shaped.

[0031] like Figure 3 As shown, in this embodiment, a brush 5 is further provided on the sidewall of the limiting cavity 21 to prevent the copper wire from being scratched. Preferably, the brush 5 is provided on the sidewall of the limiting cavity 21 away from the lever 41, i.e., the front sidewall. Therefore, the brush 5 ensures that the copper wire end adheres to the brush 5 as it moves upward, preventing direct contact with the sidewall of the limiting cavity 21 and thereby preventing damage.

[0032] like Figures 1-6 As shown, in this embodiment, the wire-digging drive device 42 is installed on the outer surface of the limit box 2 through the positioning seat 43 to facilitate positioning of the wire-digging mechanism 4.

[0033] like Figure 1 and Figure 2 As shown, in this embodiment, two limit boxes 2 and two wire-digging mechanisms 4 are symmetrically provided, respectively; the wire-hooking mechanism 3 can be used to cooperate with the two limit boxes 2 and the two wire-digging mechanisms 4. Therefore, through the above arrangement, the winding efficiency of the present invention can be improved.

[0034] like Figure 3-Figure 6 As shown, the thread hooking mechanism 3 includes a movable plate 31 that can move up and down and has its two ends extending into the two limiting cavities 21 respectively, two hooks 32 respectively mounted on the movable plate 31, and a hook thread driving assembly 33 for driving the movable plate 31 to move up and down; each hook thread 32 is provided with a hook groove corresponding to the copper wire; a shift lever 41 is located on one side of the hook thread 32. Specifically, in the original state, the shift lever 41 is located at the rear side of the hook thread 32, and when the shift lever 41 moves forward, it is located at the front side of the hook thread 32; in addition, a strip hole for the movable plate 31 to move is provided on the side plates of the two limiting boxes 2, respectively. However, the strip hole should not be too wide, and the two ends of the movable plate 31 extend into the two limiting cavities 21 respectively through the strip hole; the two hook threads 32 are respectively provided on the two ends of the movable plate 31. Therefore, the hook thread driving assembly 33 can stably push the hook threads 32 to achieve up and down movement. In addition, since the overall structure of the hook line driving assembly 33 is the existing technology, mainly the motor drives the movable plate 31 to move by cooperating with the screw rod, so it is not further described here.

[0035] like Figure 6As shown, in other embodiments, the motor 421 or the rotary cylinder 422 in the wire-pulling drive device 42 can also be replaced by a telescopic cylinder 423; the shifting rod 41 can be mounted on the output shaft of the telescopic cylinder 423 so as to be movable back and forth. Therefore, after the wire-pulling drive device 42 adopts the telescopic cylinder 423, the shifting rod 41 can be transformed from swinging back and forth to moving back and forth, but the function of the shifting rod 41 is the same, that is, it is also used to shift the copper wire. Of course, the shape of the perforation 22 at this time is similar to the moving path of the shifting rod 41, that is, a straight bar.

[0036] like Figure 1-Figure 3 As shown, to facilitate coordination with the wire hooking mechanism 4, a guide wire mechanism 6 is also provided on the frame 1. This guide wire mechanism 6 is used to guide the end of the copper wire to the top of the magnetic ring. Specifically, the guide wire mechanism 6 includes two guide pulleys for guiding the end of the copper wire to the top of the magnetic ring, and a guide wire drive assembly for driving the guide pulleys to perform corresponding movements. More specifically, the guide wire drive assembly is used to drive the guide pulleys to move in the front-back, left-right, and up-down directions. However, since the structure of the guide wire mechanism 6 is conventional, it will not be further described here.

[0037] The specific operating principle of the utility model is introduced below to facilitate understanding of the utility model:

[0038] refer to Figure 7 First, the various mechanisms of the utility model are set at corresponding positions of the winding machine;

[0039] Next, when the end of the copper wire is located at the preset position of the magnetic ring, the hook wire driving assembly 33 drives the movable plate 31 and the hook needle 32 to move upward to the preset position;

[0040] Next, the hook thread driving assembly 33 drives the movable plate 31 and the hook needle 32 to move downward until the end of the copper wire is pulled into the preset position of the limit cavity 21, and the hook needle 32 finally stops below the lever 41; at this time, the lever 41 is in the original position, specifically, at the rear side of the hook needle 31, so that the lever 41 can prevent the normal downward movement of the hook needle 31 from being affected by the lever 41;

[0041] Next, the wire driving device 42 drives the lever 41 to move forward (specifically, it can be swung or moved horizontally) until it pushes the end of the copper wire to the front side of the limiting cavity 21 (i.e. Figure 3 The brush 5 shown in the figure moves to a preset position, which limits the swing range of the copper wire end to form a limit for the copper wire; at the same time, the wire guide mechanism 6 is activated and gradually guides the copper wire end in the limit cavity 21 to above the magnetic ring. During the movement of the copper wire, the copper wire can slide on the surface of the brush 5 to avoid being scratched, that is, the brush 5 can be used to protect the copper wire;

[0042] Next, when all the copper wires are moved into place, the wire driving device 42 drives the lever 41 to move backward and reset;

[0043] Next, the hook line driving assembly 33 drives the movable plate 31 and the hook needle 32 to move upward to the preset position again, and then continues to repeat the above steps.

[0044] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the scope of the claims and equivalent technologies of the present invention, the present invention is also intended to include these changes and modifications.
