Description

Technical Field

[0001] The utility model relates to the field of winding machines, and specifically relates to a wire-hooking mechanism of an improved differential-mode inductor winding machine. Background Technique

[0002] Differential-mode inductance is a property of a closed loop, that is, when the current passing through the closed loop changes, an electromotive force will appear to resist the change of the current. This kind of inductance is called self-inductance, which is the property of the closed loop itself. Most electrical products need to use copper wire to wind an inductor coil on a magnetic ring. During the production process of differential-mode inductors, a winding machine is required to wind the wire.

[0003] For a differential-mode inductor winding machine, application publication number CN117476362A discloses a differential-mode inductor automatic winding machine and a winding method. Among them, the differential-mode inductor automatic winding machine specifically discloses including a machine frame and a vibrating disk, a feeding manipulator, a magnetic-ring clamping mechanism, a wire supply and pulling mechanism, a wire guiding mechanism, a wire-hooking mechanism, a flipping mechanism, and a wire-adjusting mechanism that are respectively installed on the machine frame and cooperate with each other; the vibrating disk can be used to output magnetic rings on an output channel; the feeding manipulator can be used to clamp the magnetic rings on the vibrating disk to the magnetic-ring clamping mechanism; the magnetic-ring clamping mechanism includes two groups of clamping components arranged oppositely in the left-right direction, and the two groups of clamping components can be used to clamp the magnetic rings and drive the magnetic rings to rotate horizontally; the wire supply and pulling mechanism includes a wire supply positioning plate movably installed horizontally on the machine frame, a wire supply component installed on the wire supply positioning plate, and a wire pulling component that can clamp the copper wire and drive the wire supply positioning plate to move in the in-out direction; the wire supply component can be used to limit the copper wire, and the wire pulling component can be used to cooperate with the wire-adjusting mechanism and pull the wire head of the copper wire on the magnetic ring outwards, so that the copper wire fits more closely with the magnetic ring; the wire guiding mechanism includes a wire guiding wheel that can move in the front-back, left-right, and up-down directions, and the wire guiding wheel can be used to guide and push the wire head of the copper wire above the magnetic ring for the wire-hooking mechanism to hook; the wire-hooking mechanism can be used to pull the wire head of the copper wire above the magnetic ring from the central hole of the magnetic ring downwards; the flipping mechanism includes a rotating clamping cylinder that can move in the front-back and up-down directions, and the rotating clamping cylinder can be used to flip the magnetic ring after the first wire head of the copper wire is wound on the magnetic ring, so as to continue to complete the winding of the second wire head subsequently; the wire-adjusting mechanism includes a wire-adjusting finger cylinder that can move up and down and back and forth and can cooperate with the rotation of the magnetic ring; the wire-adjusting finger cylinder can be used to clamp the wire head of the copper wire and rotate in the same direction as the magnetic ring, and the wire-adjusting mechanism can also be used to bend the wire head of the copper wire outwards by a certain distance during the winding process and cooperate with the wire supply and pulling mechanism to pull the copper wire outwards.

[0004] However, for the wire-hooking mechanism of the above-mentioned wire winding machine, there is still room for improvement. For example, during the downward movement of the hook block of the wire-hooking mechanism, since it directly pulls the copper wire to pass downward through the magnetic ring in a bent shape, but due to the large number of components of the wire winding machine and some copper wires being relatively long. Therefore, during the downward movement of the copper wire, the copper wire is very likely to hit other components due to swinging, and may even cause damage to the components, which will further lead to damage to the machine.

[0005] Therefore, it is necessary to improve the existing technology. Utility Model Content

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

[0008] An improved wire-hooking mechanism for a differential-mode inductor wire winding machine, including a wire-hooking mechanism for being installed on a frame; the wire-hooking mechanism includes a movable plate that can move up and down, two hook needles respectively installed at both ends of the movable plate, two limiting cavities respectively corresponding to the two hook needles, and a driving component for driving the movable plate to move up and down; a hook groove corresponding to the copper wire is respectively arranged on each hook needle; a vertically extending and upwardly open strip-shaped hole is respectively arranged on the side walls of the two limiting cavities facing each other; at least one group of blocking members is arranged in each strip-shaped hole; each group of blocking members includes two soft elastic plates respectively arranged on both sides of the strip-shaped hole and capable of overlapping each other; both ends of the movable plate are respectively placed in the two strip-shaped holes; after the driving component drives the movable plate to move downward, the movable plate will sequentially push the two elastic plates of each group of blocking members to separate from each other and the elastic plates reset after the movable plate leaves, and at the same time, the two hook needles can respectively pull the copper wire downward into the two limiting cavities, so as to be able to use the side walls of the limiting cavities and the elastic plates to limit the copper wire to prevent it from exceeding the range of the limiting cavities.

[0009] The following technical solutions are also included:

[0010] Further, at least one group of vertically extending brushes is respectively arranged on the front side wall and the rear side wall of each limiting cavity facing each other, so as to prevent the copper wire from being scratched by the brushes.

[0011] Further, each of the limiting cavities has a shape that is wider at the lower end and narrower at the upper end, so as to provide sufficient space for placing the copper wire and avoid serious bending of the copper wire.

[0012] Further, two groups of the brushes are arranged up and down at the upper end of the front side wall of each of the limiting cavities; one group of the brushes is arranged at the upper end of the rear side wall of each of the limiting cavities.

[0013] Further, one group of the brushes that are inclined upward and outward from top to bottom is further arranged at the top of the front side at the lower end of each of the limiting cavities, so as to play a role in protecting the copper wire during the process of pulling the copper wire upward and avoid scratching the copper wire.

Through the above settings, it is convenient to drive the crochet hook to move.

[0017] Further, the peripheral side walls and the lower end of each of the limiting cavities are fixed plates, so that each of the fixed plates can be used to enclose the limiting cavity; the strip-shaped holes are also correspondingly arranged on the fixed plates.

[0018] Further, two of the fixed plates that face outward and are arranged back to back in the two limiting cavities are both transparent, so that the staff can conveniently observe the situation inside the limiting cavity.

[0032] The following further elaborates on the utility model in conjunction with the drawings and specific embodiments. The following description is only exemplary and does not limit the protection scope of the utility model.

[0033] As Figures 1 - 6As shown in the figure, a wire-hooking mechanism of an improved differential-mode inductor winding machine includes a wire-hooking mechanism for being installed on a frame 1; the wire-hooking mechanism includes a movable plate 2 that can move up and down, two wire hooks 3 respectively installed at both ends of the movable plate 2, two limiting cavities 4 respectively corresponding to the two wire hooks 3, and a driving assembly for driving the movable plate 2 to move up and down; a hook groove corresponding to the copper wire (not shown in the figure) is respectively arranged on each wire hook 3; a vertically extending strip-shaped hole 5 with an open upper end is respectively arranged on the side walls of the two limiting cavities 4 opposite to each other; at least one set of blocking members is arranged in each strip-shaped hole 5; each set of blocking members includes two elastic plates 6 that are respectively arranged on both sides of the strip-shaped hole 5 and can overlap each other and are soft, so there will be no gap through which the copper wire can pass between the two overlapping elastic plates 6, so that it can block the copper wire well; both ends of the movable plate 2 are respectively placed in the two strip-shaped holes 5, and the middle part of the movable plate 2 is located between the two limiting cavities 4; after the driving assembly drives the movable plate 2 to move downwards, the movable plate 2 will sequentially push the two elastic plates 6 of each set of blocking members to separate from each other and the elastic plates 6 will reset after the movable plate 2 leaves, and at the same time, the two wire hooks 3 can respectively pull the copper wire downwards into the two limiting cavities 4, so as to be able to limit the copper wire by the side walls of the limiting cavities 4 and the elastic plates 6 to prevent it from exceeding the range of the limiting cavities 4.

[0034] Therefore, by using the setting of the limiting cavity 4 in the present utility model, after the wire hook 3 hooks the copper wire downwards and moves it downwards, the copper wire can enter the limiting cavity 4, so that the limiting cavity 4 can be used to limit the swing of the copper wire and prevent it from hitting other components (such as important components) outside the limiting cavity 4 due to the swing, so as to avoid damage to the components outside the limiting cavity 4 and achieve the effect of protecting the components, that is, it can prevent the overall winding machine from malfunctioning. Due to the elastic deformation setting of the elastic plate 6, the movable plate 2 can move smoothly in the strip-shaped hole 5, that is, it can conveniently drive the wire hook 3 to move, and after the elastic plate 6 returns to its original state, it can seal the strip-shaped hole 5, so as to be used to block the copper wire to avoid the copper wire from getting out of the range of the limiting cavity 4. In addition, since two wire hooks 3 are arranged on the movable plate 2 in the present utility model, and two limiting cavities 4 are also arranged in cooperation with the two wire hooks 3, the effect of simultaneously and safely hooking wires at two stations can be achieved, greatly improving the working efficiency.

[0035] As Figure 3 and Figure 4 As shown in the figure, preferably, at least one set of vertically extending brush hairs 7 are respectively arranged on the front side wall and the rear side wall of each limiting cavity 4 opposite to each other, so as to prevent the copper wire from being scratched by the brush hairs 7. Of course, these brush hairs 7 can also play a role in combing the copper wire to a certain extent, and have strong practicability.

[0036] As Figure 3 andFigure 4 As shown, in this embodiment, each limiting cavity 4 is shaped with a wider lower end and a narrower upper end. Therefore, through this arrangement, when the crochet hook 3 hooks the copper wire downward, the wider lower end of the limiting cavity 4 can be used to place the slightly bent copper wire, so as to avoid the situation that the copper wire is severely bent due to insufficient space in the limiting cavity 4.

[0037] As Figure 3 and Figure 4 shown, specifically, the longitudinal section of the upper end of the limiting cavity 4 is generally rectangular, while the longitudinal section of its lower end is similar to a pentagonal shape.

[0038] As Figure 3 and Figure 4 shown, in this embodiment, two groups of brushes 7 are arranged up and down at the upper end of the front side wall of each limiting cavity 4; one group of brushes 7 is arranged at the upper end of the rear side wall of each limiting cavity 4. Therefore, the total area of the two groups of brushes 7 on the front side wall of the limiting cavity 4 is larger than the total area of the one group of brushes 7 on its rear side wall, so that if the copper wire swings forward during the downward movement, more brushes 7 can be used to well protect the copper wire.

[0039] As Figure 3 and Figure 4 shown, preferably, a group of brushes 7 are also arranged at the front side top of the lower end of each limiting cavity 4, which are inclined downward and outward from top to bottom. That is, this group of brushes 7 is mainly used to protect and comb the slightly bent copper wire during its upward movement, so as to prevent the copper wire from being scratched.

[0040] As Figure 3 and Figure 4 shown, preferably, a swing control plate 8 extending downward to the lower end of the limiting cavity 4 is also arranged below the brush 7 on the rear side wall of the limiting cavity 4, so as to be able to limit the copper wire and prevent problems caused by excessive swing of the copper wire.

[0041] As Figures 1 - 5 shown, in this embodiment, multiple groups of blocking members are arranged in each strip-shaped hole 5, so as to be able to well block the copper wire and avoid the problem that the copper wire comes out of the limiting cavity 4.

[0042] As Figure 1 and Figure 2As shown, preferably, the driving component includes a positioning plate 9 connected to the frame 1, a motor 10 mounted on the positioning plate 9, a driving wheel 11 mounted on the output shaft of the motor 10, a driven wheel 12 mounted on the positioning plate 9, and a belt (not shown in the figure) respectively connected to the driving wheel 11 and the driven wheel 12; the moving plate 2 is mounted on the belt. Therefore, the motor 10 is used to drive the driving wheel 11, and the driving wheel 11 cooperates with the driven wheel 12 and the belt to enable the moving plate 2 to move, and finally the crochet hook 3 to move synchronously.

[0043] As Figures 1 - 4 shown, specifically, the peripheral side walls and the lower end of each limiting cavity 4 are fixed plates 13, so that the limiting cavity 4 can be surrounded by each fixed plate 13; the strip-shaped holes 5 are also correspondingly arranged on the fixed plate 13. In addition, the top of the limiting cavity 4 is not provided with a fixed plate 13, so that the crochet hook 3 can conveniently enter the limiting cavity 4.

[0044] Specifically, two fixed plates 13 facing outward and arranged back to back in the two limiting cavities 4 are both transparent, so that the situation inside the limiting cavity 4 can be conveniently observed through the transparent fixed plates 13, and it can be known in time if the machine jams or a component fails. For these two transparent fixed plates 13, specifically Figure 1 the left and right fixed plates 13 respectively marked in

[0045] In this embodiment, the elastic plate 6 is a rubber plate so that the elastic plate 6 has deformation elasticity. However, those skilled in the art should know that for the material of the elastic plate 6, other materials can also be used, which will not be elaborated here.

[0046] The following introduces the specific working principle of the present invention for understanding the present invention:

[0047] Refer to Figure 6, first, the hook wire mechanism of the present utility model is arranged on the corresponding frame 1 of the differential mode inductor winding machine; next, when the first end of the copper wire winds a coil on the magnetic ring, the motor 10 drives the moving plate 2 to move upward to a preset position; next, the motor 10 drives the moving plate 2 to move downward again. At the same time, the hook needle 3 will synchronously hook the copper wire downward until the copper wire enters the limiting cavity 4; next, during the downward movement of the moving plate 2, each elastic plate 6 will be pushed open in sequence to smoothly move the hook needle 3 downward into the limiting cavity 4, and after the elastic plate 6 leaves the moving plate 2, it starts to reset to the superposed state; next, during the downward movement of each copper wire, it will contact the corresponding brush 7 in the limiting cavity 4 to prevent the copper wire from being scratched, and the swing control plate 8 can be used to limit the copper wire when its swing amplitude is large; of course, other fixing plates 13 can also limit the copper wire to a certain extent; next, when the copper wire moves in place, its end will just be placed in the protruding side at the lower end of the limiting cavity 4 (i.e., Figure 3 the right side of the lower end shown), so that it can be protected and combed by the brush 7 above it when it is pulled upward.

[0048] The present utility model is not limited to the above embodiments. If various modifications or deformations of the present utility model do not depart from the spirit and scope of the present utility model, and provided that these modifications and deformations fall within the scope of the claims of the present utility model and equivalent technical scope, then the present utility model also intends to include these modifications and deformations.
