The winding device and the winding apparatus thereof according to the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 9, a winding device according to an embodiment of the present invention is adapted to wind a wire around a side column 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 can be inserted vertically, and a winding channel H11 extending to the station slot H10, a side wall of the station slot H10 has a notch H101, and the winding channel H11 is configured such that a wire can be bent and wound onto the side pillar 601 of the closed magnetic core 60 to form a coil after passing through the winding channel H11.

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 a wire, typically an enameled wire, is fed into the winding channel H11 by the wire feeding mechanism. The wire can move along the winding channel H11, and after passing through the outlet end of the winding channel H11, the wire can be bent and wound on the side column 601 with closed magnetism to form a coil, so that the structure is simple, and the winding is reliable and stable.

The holding assembly 20 is disposed at the gap H101 and can be closed to hold the start end 61 of the coil or opened to release the start end 61 of the coil. A drive mechanism is coupled to the clamping assembly 20 for driving the clamping 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 close to the station groove 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 groove H10 so as to elongate the start end 61 to form a thread end.

That is, the clamping assembly 20 can perform an opening or closing action to clamp or release the start 61 of the coil on the closed core in the station slot H10. The first driving device 30 can drive the clamping assembly 20 to move between the first position and the second position, and then the clamping assembly 20 is used to pull the starting end 61 of the coil to form the thread end.

In the specific 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 output through the wire outlet end of the winding channel H11 and then is wound on the side pillar 601 of the closed magnetic core 60, preferably, the wire feeding can be stopped when the wire is not completely wound on the side pillar 601, for example, the wire feeding is stopped after the wire is wound for the first circle, at this time, the clamping assembly 20 is driven to move from the second position to the first position through the first driving device 30, that is, the clamping assembly 20 moves into the notch H101 and is close to the station slot H10, the clamping assembly 20 is closed to clamp the starting end 61 of the wire on the side pillar 601, then, the clamping assembly 20 is driven to move from the first position to the second position through the first driving device 30, so that the clamping assembly 20 clamps the starting end 61 of the wire and pulls the wire outwards for a certain distance to form a wire end, then, the clamping assembly 20 releases the starting end 61 of the wire, the wire feeding mechanism continues to feed the 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 wire.

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

According to the winding device provided by the embodiment of the invention, the clamping component 20 is arranged at the notch H101 of the winding component 10, the first driving device 30 drives the clamping component 20 to move between the first position and the second position, when the clamping component 20 is located at the first position, the clamping component 20 is located in the notch H101 and is close to the station groove H10, the starting end 61 of the coil can be clamped by the clamping component 20, and when the clamping component 20 moves from the first position to the second position, the clamping component 20 moves in the notch H101 in the direction far away from the station groove H10 to elongate the starting end 61 to form a coil head.

Referring to fig. 2 and 4, in an embodiment of the present invention, the winding assembly 10 includes a winding base 101, a cover plate 102 and a second driving device 103, a winding slot H112 and a wire guiding slot H111 are disposed on a top surface of the winding base 101, in an example of fig. 1, the winding base 101 includes a base 101a and an upper base 101b, and the winding slot H112 and the wire guiding slot H111 are disposed on the upper base 101 b. The winding slot H112 is formed in a circular arc shape and is wound outside the station slot H10, preferably, the center of the circular arc-shaped winding slot H112 is located on the axis of the side pillar 601, and illustratively, the station slot H10 has an arc-shaped edge surrounding the outside of the side pillar 601, and the winding slot H112 extends along the arc-shaped outside. The wire guiding groove H111 is formed in a linear shape and is connected and communicated with the winding groove H112 to form the winding passage H11, and the wire guiding groove H111 facilitates the wire to be conveyed to the winding groove H112.

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

The cover plate 102 is slidably disposed on the winding base 101. The second driving device 103 is connected to the cover plate 102 for driving the cover plate 102 to slide to close or open the winding passage H11. Preferably, a thin covering sheet 1021 is disposed on the cover plate 102 at a position opposite to the winding slot H112, and the covering sheet 1021 extends along the winding slot H112 and covers over 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, so as to close the wire groove H111 and the winding groove H112, or open the wire groove H111 and the winding groove H112, so as to ensure that the wire is conveyed along the winding path H11 when the wire groove H111 and the winding groove H112 are closed, so as to ensure smooth winding, and so as to take out the closed magnetic core 60 from the station groove H10 or load the closed magnetic core 60 into the station groove H10 when the wire groove H111 and the winding groove H112 are opened.

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

Referring to fig. 2, 3, 5, 8 to 9, in some embodiments of the present invention, 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 the floating support 40, and the closed magnetic core 60 is supported by the floating support 40.

A linkage 50 is provided between the clamping assembly 20 and the floating support 40 to drive the floating support 40 to switch between the upper and lower positions in response to movement of the clamping assembly 20.

When the clamping assembly 20 is in the second position, the link 50 forces the floating support 40 to be in the floating position such that the outlet end of the winding channel H11 is opposite to the lower end of the closed magnetic side post 601, and when the clamping assembly 20 moves from the second position to the first position, the link 50 forces the floating support 40 to be lowered to the lowered position such that the outlet end of the winding channel H11 is opposite to the middle position of the closed magnetic side post 601.

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 upper floating position and the lower floating position through the linkage 50, so as to raise and lower the closed magnetic core 60.

In the particular winding process, in the initial state, the clamping assembly 20 is in the second position, in which the floating support 40 is in the floating position, and correspondingly, the outlet end of the winding channel H11 is opposite to the lower end of the closed magnetic side pillar 601. The wire feeding mechanism is utilized to feed wires into the winding channel H11, the wires can be wound on the side column 601 of the closed magnetic core 60 from bottom to top after being output through the wire outlet end of the winding channel H11, the wire feeding is stopped after the wires are wound on the side column 601 for a certain number of turns (for example, wound for a first turn), the clamping assembly 20 is driven by the first driving device 30 to move from the second position to the first position, and the clamping assembly 20 moves into the notch H101 and is close to the station slot H10.

At the same time, the link 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, the wire is conveyed in the winding channel H11 of the winding assembly 10, and the winding assembly 10 is fixed, so that the closed magnetic core 60 descends, the outlet end of the winding channel H11 is opposite to the middle position of the closed magnetic side column 601, correspondingly, the first coil of the winding is located at the middle position of the side column 601, and when the position is reached, the clamping assembly 20 is closed again to clamp the starting end 61 of the wire on the side column 601.

Then, the clamping assembly 20 is driven by the first driving device 30 to move from the first position to the second position, so that the clamping assembly 20 clamps the starting end 61 of the wire and pulls outwards for a certain distance to form a wire end, and the clamping assembly 20 releases the starting end 61 of the wire. In the process, the link 50 drives the floating support 40 to return to the floating position as the clamping assembly 20 moves, i.e. the outlet end of the winding channel H11 is opposite to the lower end of the closed magnetic side pillar 601, and correspondingly, the first coil is returned to the lower end position of the side pillar 601. The wire feeding mechanism continues to feed the 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 wire.

In this embodiment, the floating support 40 is driven to switch between the floating position and the sinking position through the linkage of the linkage 50, so that when the start end 61 of the coil needs to be pulled by the clamping assembly 20, the floating support 40 can be switched to the sinking position, and the coil of the first turn is kept at the middle position of the side pillar 601, so that when the clamping assembly 20 is close to the closed magnetic core 60, the interference with the closed magnetic core 60 is avoided, the clamping assembly can be directly inserted into the hole of the closed magnetic core 60 to clamp the start end 61 of the wire rod, in other words, the clamping assembly 20 can be ensured to reliably clamp the start end 61 of the wire rod without mechanical interference in a minimum space. And after drawing and forming the end of a thread, can make floating support piece 40 resume to the come-up position, the first circle coil of coiling resumes to the lower extreme position of side post 601, and then can continue to accomplish follow-up wire winding, its simple structure, linkage design benefit ensures that end of a thread and wire winding are drawn stably orderly.

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

One end of the linkage ejector rod 501 is connected to the clamping assembly 20, and 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 member 50 forces the floating support 40 to overcome the elastic force of the elastic member 502 to descend to the sinking position.

That is, when the clamping assembly 20 is at the second position, the clamping assembly 20 is forced to be kept at the floating position toward the floating support 40 under 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 rod 501 to move toward the floating support 40, and the linkage rod 501 generates a downward force on the floating support 40, so that the floating support 40 is forced to fall to the sinking position against the elastic force of the elastic member 502. In addition, after the clamping assembly 20 clamps the starting end 61 of the wire, in the process that the first driving device 30 drives the clamping member to return to the second position from the first position, the linkage ejector rod 501 moves the clamping assembly 20 in the direction away from the floating support 40, so that the linkage ejector rod 501 cancels the downward acting force on the floating support 40, the elastic member 502 recovers the deformation, and the floating support 40 is forced to rise to the floating position, thereby realizing the linkage driving of the floating support 40, having a simple structure, and ensuring that the floating support 40 can be reliably switched between the floating position and the sinking position.

Advantageously, an opening H40 is provided on the floating support 40, a pressure receiving surface S40 is provided in the opening H40, the other end of the linkage ejector 501 is slidably inserted into the opening H40, and the other end of the linkage ejector 501 is provided with an inclined driving surface located above the pressure receiving surface S40, and the inclined driving surface applies downward pressure to the pressure receiving surface S40 when the clamping assembly 20 moves to the first position, so that the floating support 40 descends to the sinking position.

That is, when the first driving device 30 drives the clamping assembly 20 to move from the second position to the first position, the linkage ejector 501 moves in a direction approaching the floating support 40, and the inclined driving surface on the linkage ejector 501 generates a downward pressure on the pressure receiving 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 rod 501 moves away from the floating support 40, and the inclined driving surface on the linkage rod 501 gradually releases the pressure receiving surface S40, so that the floating support 40 returns to the floating position under the action of the elastic member 502.

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

Referring to fig. 2, 4 to 7, in an embodiment of the present invention, the clamping assembly 20 includes an upper jaw 201, a lower jaw 202 and a third driving device 203, wherein the lower jaw 202 is disposed opposite to the upper jaw 201; a third driving device 203 is connected with the upper jaw 201 and/or the lower jaw 202 for driving the upper jaw 201 and the lower jaw 202 to move relatively to open or close; the upper jaw 201 and the lower jaw 202 are formed in a shape of a sharp mouth so as to be able to protrude into a gap between two side legs 601 of the closed magnetic core 60.

When the wire needs to be clamped or unclamped, the upper jaw 201 and the lower jaw 202 can be driven by the third driving device 203 to be closed relatively close to each other or opened relatively far away from each other, and the clamping is reliable. In addition, the upper clip 201 and the lower clip 202 form a sharp mouth shape, so as to conveniently extend into the hole of the closed magnetic core 60 with extremely small space, and avoid mechanical interference with the closed magnetic core 60.

Referring to fig. 4 to 7, in an embodiment of the present invention, the clamping assembly 20 further includes a mounting base 204 and a push rod 205 slidably disposed on the mounting base 204, the lower clip 202 is mounted on the top of the mounting base 204, and the upper clip 201 is located above the lower clip 202 and connected to the upper end of the push rod 205; the third driving device 203 is installed at the bottom of the installation base 204 and connected to the push rod 205, so as to drive the push rod 205 to slide up and down.

When the clamping assembly 20 needs to be opened, the third driving device 203 can drive the push rod 205 to slide upwards so as to push the upper clamping piece 201 to move upwards and open, and when the clamping assembly 20 needs to be closed, the third driving device 203 can drive the push rod 205 to slide downwards so as to push the upper clamping piece 201 to move downwards and close.

Advantageously, the top of the floating support 40 is provided with a magnetic attraction member for attracting the closed magnetic core 60, so that when the closed magnetic core 60 is inserted into the station groove H10, the lower end of the closed magnetic core 60 is in contact with the top of the floating support 40, and the closed magnetic core 60 is attracted by the magnetic attraction member, thereby making it possible to ensure that the closed magnetic core 60 can be stably and reliably lifted and lowered along with the floating support 40 when the floating support 40 is switched between the floating position and the sinking position. In addition, the closed magnetic core 60 is not easily separated from the station groove H10, and stability in winding can be maintained.

Referring to fig. 1 to 2 and 4, in some embodiments of the present invention, the winding device further includes a wire cutting base 70 and a fourth driving device 71, wherein the wire cutting base 70 is disposed adjacent to the winding assembly 10, and the wire cutting base 70 has a wire feeding passage therein communicating with a wire feeding end of the winding passage H11. The fourth driving device 71 is connected to the winding assembly 10 for driving the winding assembly 10 to move and displace relative to the wire cutting seat 70, so that the wire is cut at the wire cutting seat 70.

After the winding is completed, the winding assembly 10 driven by the fourth driving device 71 moves relative to the wire cutting seat 70 to be displaced (e.g., moves upward) so as to cut the wire at the wire cutting seat 70, so that after the wire is cut, the coil can form a terminal end, and then the winding channel H11 is opened through the cover plate 102, so that the wound closed magnetic core 60 can be taken out, and thus, the wire end and the finished product can be conveniently separated at the terminal end.

It is understood that the first driving device 30, the second driving device 103, the third driving device 203 and the fourth driving device 71 may be air cylinders or other linear drivers.
