The following describes a winding device and a winding apparatus thereof according to an embodiment of the present utility model in detail with reference to the accompanying drawings.

Referring to fig. 1 to 9, a winding device according to an embodiment of the present utility model is suitable for winding a wire on a leg 601 of a closed magnetic core 60, and includes a winding assembly 10, a clamping assembly 20 and a first driving device 30.

Specifically, the winding assembly 10 has a station slot H10 into which the closed magnetic core 60 is inserted vertically, and a winding channel H11 extending to the station slot H10, wherein a sidewall of the station slot H10 has a notch H101, and the winding channel H11 is configured such that a wire material can be wound on a side post 601 of the closed magnetic core 60 in a bending manner after passing through the winding channel H11 to form a coil.

That is, the closed magnetic core 60 can be vertically inserted into the station slot H10 of the winding assembly 10, and in a specific application, a wire feeding mechanism is disposed at one side of the winding assembly 10, and the wire is typically an enamel wire and is conveyed into the winding channel H11 by the wire feeding mechanism. The wire rod can move along the winding channel H11, and after the wire rod passes through the outlet end of the winding channel H11, the wire rod can be bent and wound on the side column 601 of the closed magnetic core to form a coil, so that the structure is simple, and the winding is reliable and stable.

The clamping assembly 20 is provided at the gap H101 and can be closed to clamp the coil start end 61 or opened to release the coil start end 61. A drive device is coupled to the clamp assembly 20 for driving the clamp assembly 20 between the first position and the second position.

When the clamping assembly 20 is located at the first position, the clamping assembly 20 is located in the notch H101 and is close to the station slot H10, so as to clamp the start end 61 of the coil by the clamping assembly 20, and when the clamping assembly 20 moves from the first position to the second position, the clamping assembly 20 moves in the notch H101 in a direction away from the station slot H10, so that the start end 61 is elongated to form a wire end.

That is, the clamping assembly 20 may perform an opening or closing action to thereby effect clamping or releasing of the start end 61 of the coil on the closed core in the station slot H10. The first driving device 30 can drive the clamping assembly 20 between the first position and the second position, and further, the clamping assembly 20 is utilized to pull the starting end 61 of the coil to form the thread end.

In the winding process, in the initial state, the clamping assembly 20 is located at the second position, the closed magnetic core 60 is vertically inserted into the station slot H10, the wire is fed into the winding channel H11 through the wire feeding mechanism, the wire is wound on the side post 601 of the closed magnetic core 60 after being output through the wire outlet end of the winding channel H11, preferably, the wire feeding can be stopped when the wire is not completely wound on the side post 601, for example, the wire feeding is stopped after winding for a first circle, at this time, the clamping assembly 20 is driven by the first driving device 30 to move from the second position to the first position, that is, the clamping assembly 20 moves into the gap H101 and approaches the station slot H10, the clamping assembly 20 is closed to clamp the starting end 61 of the wire on the side post 601, then, the first driving device 30 drives the clamping assembly 20 to move from the first position to the second position, so that the starting end 61 of the wire is clamped by the clamping assembly 20 and pulls outwards for a certain distance to form a wire head, then the starting end 61 of the wire is loosened by the clamping assembly 20, and the mechanism continues to wind on the side post 601 to form a coil with a plurality of circles.

It should be noted that, if the coil is not completely wound by the pulling action of the clamping assembly 20, the distance that the starting end 61 of the wire clamped by the clamping assembly 20 is pulled outwards should not be too long, so that the wire end formed after pulling still can pass through between the two side posts 601 of the closed magnetic core 60, and further the wire end is not blocked by the other side post 601 on the opposite side in the subsequent wire feeding process, but passes through the gap between the two side posts 601, and continues to be wound on the side posts 601, thereby completing the winding of the coil.

According to the winding device provided by the embodiment of the utility model, the clamping assembly 20 is arranged at the notch H101 of the winding assembly 10, the clamping assembly 20 is driven to move between the first position and the second position by the first driving device 30, when the clamping assembly 20 is positioned at the first position, the clamping assembly 20 is positioned in the notch H101 and is close to the station slot H10, the starting end 61 of the coil can be clamped by the clamping assembly 20, and when the clamping assembly 20 moves from the first position to the second position, the clamping assembly 20 moves in the notch H101 in the direction away from the station slot H10 to elongate the starting end 61 to form a wire end, so that the coil wound on the closed magnetic core 60 of the winding device has the wire end, thereby facilitating subsequent hitching legs, improving the efficiency.

Referring to fig. 2 and 4, in an embodiment of the present utility model, the winding assembly 10 includes a winding seat 101, a cover 102 and a second driving device 103, a winding slot H112 and a wire slot H111 are provided on a top surface of the winding seat 101, and in the example of fig. 1, the winding seat 101 includes a base 101a and an upper seat 101b, and the winding slot H112 and the wire slot H111 are provided on the upper seat 101 b. The winding groove H112 is formed in a circular arc shape and is wound on the outer side of the station groove H10, preferably, the center of the circular arc-shaped winding groove H112 is located on the axis of the side post 601, and the station groove H10 has an arc edge surrounding the outer side of the side post 601, and the winding groove H112 extends on the outer side of the arc shape and along the arc shape. The wire groove H111 is formed in a straight line shape and is connected to and communicates with the wire groove H112 to form the wire winding path H11, and the wire groove H111 facilitates feeding of the wire to the wire groove H112.

In a specific winding process, the wire can be conveyed into the wire guide groove H111 by the wire feeding mechanism, and then guided to the wire guide groove H112 by the wire guide groove H111, and the wire discharged from the wire outlet end of the wire guide groove H112 is bent and wound onto the side post 601 in the station groove H10 by the wire guide groove H112 because the wire guide groove H112 is formed in a circular arc shape.

The cover plate 102 is provided on the winding seat 101 and is slidable. The second driving device 103 is connected to the cover 102, and is used for driving the cover 102 to slide so as to close or open the winding channel H11. Preferably, a thin cover sheet 1021 is disposed on the cover plate 102 at a position opposite to the winding slot H112, and the cover sheet 1021 extends along the winding slot H112 and covers the winding slot H112 to close the winding slot H112.

That is, the second driving device 103 may drive the cover plate 102 to slide on the winding seat 101, thereby closing the wire slot H111 and the winding slot H112, or opening the wire slot H111 and the winding slot H112, when closing the wire slot H111 and the winding slot H112, the wire is ensured to be conveyed along the winding path H11, thereby ensuring smooth winding, and when opening the wire slot H111 and the winding slot H112, the closed magnetic core 60 may be taken out from the station slot H10 or the closed magnetic core 60 may be installed in the station slot H10.

In this embodiment, the winding channel H11 is formed by the winding slot H112 and the wire slot H111, and the winding channel H11 is opened or closed by the cover plate 102, so that, on one hand, the wire can be ensured to be stably and reliably conveyed in the winding channel H11, so as to achieve the purpose of stably and reliably winding, and on the other hand, the closed magnetic core 60 with the coil formed by winding is also conveniently taken out from the station slot H10.

Referring to fig. 2, 3, 5, and 8 to 9, in some embodiments of the present utility model, the winding device further includes a floating support 40 and a linkage 50, wherein the floating support 40 is disposed at the bottom of the station slot H10 to support the closed magnetic core 60, and when the closed magnetic core 60 is inserted into the station slot H10, the bottom of the closed magnetic core 60 contacts with the floating support 40, and the closed magnetic core 60 is supported by the floating support 40.

A linkage 50 is provided between the clamp assembly 20 and the floating support 40 for driving the floating support 40 to switch between a floating position and a sinking position in response to movement of the clamp assembly 20.

When the clamping assembly 20 is in the second position, the linkage 50 forces the floating support 40 to the floating position such that the outlet end of the winding path H11 is opposite the lower end of the leg 601 of the closed magnetic core, and when the clamping assembly 20 is moved from the second position to the first position, the linkage 50 forces the floating support 40 to the sinking position such that the outlet end of the winding path H11 is opposite the intermediate position of the leg 601 of the closed magnetic core.

That is, the first driving device 30 drives the clamping assembly 20 to move between the first position and the second position, and the clamping assembly 20 can drive the floating support 40 to switch between the floating position and the sinking position through the linkage 50, so that the closed magnetic core 60 is lifted and lowered.

In a specific winding process, in an initial state, the clamping assembly 20 is located at the second position, and at this time, the floating support 40 is located at the floating position, and correspondingly, the outlet end of the winding channel H11 is opposite to the lower end of the side post 601 of the closed magnetic core. The wire feeding mechanism is utilized to feed the wire into the winding channel H11, the wire can be wound on the side post 601 of the closed magnetic core 60 from bottom to top after being output through the wire outlet end of the winding channel H11, when the wire is wound on the side post 601 for a certain number of turns (for example, a first turn is wound), the wire feeding is stopped, the first driving device 30 drives the clamping assembly 20 to move from the second position to the first position, and the clamping assembly 20 moves into the gap H101 and approaches the station groove H10.

At the same time, the linkage 50 drives the floating support 40 to move downwards to the sinking position, the closed magnetic core 60 supported by the floating support 40 descends, and since the wire is conveyed in the winding channel H11 of the winding assembly 10 and the winding assembly 10 is fixed, the closed magnetic core 60 descends, so that the outlet end of the winding channel H11 is opposite to the middle position of the side column 601 of the closed magnetic core, and the corresponding first coil wound is located at the middle position of the side column 601, and when the position is at the middle position, the clamping assembly 20 is used for closing to clamp the starting end 61 of the wire on the side column 601.

Then, the first driving device 30 drives the clamping assembly 20 to move from the first position to the second position, so that the clamping assembly 20 clamps the starting end 61 of the wire rod and pulls the starting end 61 outwards for a certain distance to form a wire head, and the clamping assembly 20 loosens the starting end 61 of the wire rod. In this process, the linkage member 50 moves along with the clamping assembly 20 to drive the floating support member 40 to restore to the floating position, that is, the outlet end of the winding channel H11 is opposite to the lower end of the side post 601 of the closed magnetic core, and correspondingly, the wound first coil is restored to the lower end position of the side post 601. The wire feeding mechanism continues to feed wire, and the wire is continuously wound on the side column 601 through the winding channel H11 to form a coil consisting of a plurality of coils of the wire.

In this embodiment, the floating support 40 is driven to switch between the floating position and the sinking position by the linkage of the linkage member 50, so that the floating support 40 can switch to the sinking position when the start end 61 of the coil needs to be pulled by the clamping assembly 20, so that the first coil is kept at the middle position of the side post 601, thus, when the clamping assembly 20 approaches the closed magnetic core 60, interference with the closed magnetic core 60 is avoided, and the wire can be directly inserted into the hole of the closed magnetic core 60 to clamp the start end 61 of the wire, in other words, the clamping assembly 20 can be ensured to clamp the start end 61 of the wire reliably in a very small space without mechanical interference. After the wire ends are drawn, the floating support piece 40 can be restored to the floating position, the wound first coil is restored to the lower end position of the side column 601, further the subsequent winding can be continuously completed, the structure is simple, the linkage design is ingenious, and the wire ends and the winding are ensured to be drawn stably and orderly.

Referring to fig. 3 and 8 to 9, in an embodiment of the present utility model, the linkage member 50 includes an elastic member 502 and a linkage ejector rod 501, wherein the elastic member 502 is disposed in the station slot H10, the lower end of the elastic member 502 abuts against the bottom wall of the station slot H10, and the upper end of the elastic member 502 abuts against the floating support 40.

One end of a linkage ejector rod 501 is connected with the clamping assembly 20, the other end of the linkage ejector rod 501 is in linkage fit with the floating support 40, and when the clamping assembly 20 moves from the second position to the first position, the other end of the linkage 50 forces the floating support 40 to drop to the sinking position against the elastic force of the elastic member 502.

That is, when the clamping assembly 20 is at the second position, the floating support 40 is forced to be kept at the floating position by the elastic force of the elastic member 502, and when the first driving device 30 drives the clamping assembly 20 to move from the second position to the first position, the clamping assembly 20 drives the linkage ejector rod 501 to move towards the direction approaching the floating support 40, and the linkage ejector rod 501 generates a downward force on the floating support 40, so that the floating support 40 is forced to drop to the sinking position against the elastic force of the elastic member 502. In addition, after the start end 61 of the wire is clamped by the clamping assembly 20, the first driving device 30 drives the clamping member to return to the second position from the first position, and the linkage ejector rod 501 moves the clamping assembly 20 away from the floating support 40, so that the linkage ejector rod 501 removes the downward acting force on the floating support 40, and the elastic member 502 is deformed to force the floating support 40 to rise to the floating position, thereby realizing linkage driving of the floating support 40, and ensuring reliable switching between the floating position and the sinking position of the floating support 40.

Advantageously, the floating support 40 is provided with an opening H40, the opening H40 has a pressed surface S40 therein, the other end of the linkage ejector 501 is slidably disposed in the opening H40, and the other end of the linkage ejector 501 is provided with an inclined driving surface above the pressed surface S40, and the inclined driving surface applies a downward pressure to the pressed surface S40 when the clamping assembly 20 is in the first position, so as to lower the floating support 40 to the sinking position.

That is, when the first driving device 30 drives the clamp assembly 20 to move from the second position to the first position, the linked jack 501 moves in a direction approaching the floating support 40, and the inclined driving surface on the linked jack 501 generates downward pressure against the pressing surface S40 on the floating support 40, thereby lowering the floating support 40 to the sinking position. When the second driving device 103 drives the clamping assembly 20 to return from the first position to the second position, the linkage ejector rod 501 moves away from the floating support 40, and the inclined driving surface on the linkage ejector rod 501 gradually releases the compression surface S40, so that the floating support 40 is restored to the floating position under the action of the elastic member 502.

In this embodiment, the linkage ejector rod 501 slides in the opening H40 of the floating support 40, and by using the cooperation between the inclined pressing surface on the linkage ejector rod 501 and the pressed surface S40 on the floating support 40, the linkage ejector rod 501 can be ensured to be capable of pressing the floating support 40 down to the sinking position, so that the structure is simple, and the linkage is reliable and stable.
