Referring to fig. 3 to 9, in some embodiments of the present utility model, the winding device 100 includes a winding seat 10, a cover 11, and a second driving device 12, wherein a station slot H10, a winding slot H112, and a wire slot H111 are provided on a top surface of the winding seat 10, the station slot H10 is adapted for the closed magnetic core 80 to be inserted vertically, the winding slot H112 is formed into a circular arc shape and is wound on an outer side of the station slot H10, and the wire slot H111 is connected to the winding slot H112 to form a winding channel H11.

Preferably, the center of the circular arc-shaped winding groove H112 is located on the axis of the side column 801, the station groove H10 is provided with an arc-shaped edge surrounding the outer side of the side column 801, and the winding groove H112 is arranged outside the arc-shaped edge and extends along the arc-shaped edge. 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.

After winding, the wire between the wire feeding mechanism 700 and the winding seat 10 may be cut by the wire cutting assembly, and at this time, the coil 81 may be separated from the wire.

After winding, the winding device 100 driven by the ninth driving device 14 may move relative to the wire-cutting seat 13 to be offset (e.g. move upwards), so that the wire is cut at the wire-cutting seat 13, and after the wire is cut, the coil 81 may form a termination end, and then the winding channel H11 is opened by the cover 11, so that the wound magnetic core coil 81 may be taken out, thereby facilitating the formation of the wire end 811 at the termination end and the separation of the product.

Referring to fig. 3 to 9, in one embodiment of the present utility model, a side wall of the station slot H10 has a notch H101, and the winding device 100 further includes a clamping assembly 15 and a third driving device 16, where the clamping assembly 15 is disposed at the notch H101 and can be closed to clamp the start end of the coil 81 or opened to release the start end of the coil 81.

When the clamping assembly 15 is located at the first position, the clamping assembly 15 is located in the notch H101 and is close to the station slot H10, so as to clamp the start end of the coil 81 by the clamping assembly 15, and when the clamping assembly 15 moves from the first position to the second position, the clamping assembly 15 moves in the notch H101 in a direction away from the station slot H10, so that the start end is elongated to form a wire end 811.

That is, the clamping assembly 15 can perform an opening or closing action, thereby achieving clamping or releasing of the start end of the coil 81 on the closed core in the station slot H10. And the third driving device 16 can drive the clamping assembly 15 to move between the first position and the second position, so that the starting end of the coil 81 is pulled by the clamping assembly 15 to form a wire end 811.

It should be noted that, if the wire pulling action of the clamping assembly 15 is utilized before the coil 81 is not completely wound, the distance that the starting end of the wire clamped by the clamping assembly 15 is pulled outwards should not be too long, so that the wire end 811 formed after pulling still can pass through between the two side posts 801 of the closed magnetic core 80, further, the wire end 811 is not blocked by the other side post 801 on the opposite side in the subsequent wire feeding process, but passes through the gap between the two side posts 801, and continues to be wound on the side posts 801, thereby completing the winding of the coil 81.

In this embodiment, the clamping assembly 15 is disposed at the opening H101 on the winding seat 10, and the third driving device 16 drives the clamping assembly 15 to move between the first position and the second position, when the clamping assembly 15 is located at the first position, the clamping assembly 15 is located in the opening H101 and is close to the station slot H10, the starting end of the coil 81 can be clamped by the clamping assembly 15, and when the clamping assembly 15 moves from the first position to the second position, the clamping assembly 15 moves in the opening H101 in a direction away from the station slot H10 to elongate the starting end to form the wire end 811, so that the coil 81 wound on the closed magnetic core 80 by the winding device 100 has the wire end 811, which is convenient for subsequent hitching legs, improves efficiency, and in addition, the winding device has a simple structure and low cost.

A linkage 18 is provided between the clamp assembly 15 and the floating support 17 for driving the floating support 17 to switch between a floating position and a sinking position in response to movement of the clamp assembly 15.

When the clamping assembly 15 is in the second position, the linkage 18 forces the floating support 17 to the floating position such that the outlet end of the winding path H11 is opposite the lower end of the leg 801 of the closed magnetic core 80; when the clamping assembly 15 moves from the second position to the first position, the linkage 18 forces the floating support 17 to descend to the sinking position such that the outlet end of the winding path H11 is opposite the middle position of the leg 801 of the closed magnetic core 80.

That is, the third driving device 16 drives the clamping assembly 15 to move between the first position and the second position, and the clamping assembly 15 can drive the floating support 17 to switch between the floating position and the sinking position through the linkage 18, so that the closed magnetic core 80 is lifted and lowered.

At the same time, the linkage member 18 drives the floating support member 17 to move downwards to the sinking position, the closed magnetic core 80 supported by the floating support member 17 descends, and the wire is conveyed in the winding channel H11 of the winding assembly, and the winding assembly is fixed, so that the closed magnetic core 80 descends, the outlet end of the winding channel H11 is opposite to the middle position of the side column 801 of the closed magnetic core 80, and correspondingly, the first coiled wire 81 is positioned at the middle position of the side column 801, and when the position is at the middle position, the clamping assembly 15 is closed to clamp the starting end of the wire on the side column 801.

In this process, the linkage member 18 moves along with the clamping assembly 15 to drive the floating support member 17 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 column 801 of the closed magnetic core 80, and correspondingly, the wound first coil 81 is restored to the lower end position of the side column 801. The wire feeding mechanism 700 continues to feed wire, and continues to wind the wire on the side column 801 through the winding channel H11 to form a coil 81 composed of a plurality of turns of the wire.

In this embodiment, the floating support 17 is driven to switch between the floating position and the sinking position by the linkage of the linkage member 18, so that when the start end of the coil 81 needs to be drawn by the clamping assembly 15, the floating support 17 can switch to the sinking position, so that the first coil 81 is kept at the middle position of the side column 801, thus, when the clamping assembly 15 approaches the closed magnetic core 80, interference with the closed magnetic core 80 is avoided, and the wire can be directly inserted into the hole of the closed magnetic core 80 to clamp the start end of the wire, in other words, the clamping assembly 15 can be ensured to clamp the start end of the wire reliably in a very small space without mechanical interference.

That is, when the clamping assembly 15 is at the second position, the floating support 17 is forced to be kept at the floating position by the elastic force of the elastic member 182, and when the third driving device 16 drives the clamping assembly 15 to move from the second position to the first position, the clamping assembly 15 drives the linkage ejector rod 181 to move towards the direction approaching the floating support 17, and the linkage ejector rod 181 generates a downward force on the floating support 17, so that the floating support 17 is forced to drop to the sinking position against the elastic force of the elastic member 182. In addition, after the starting end of the wire is clamped by the clamping assembly 15, the third driving device 16 drives the clamping member to return to the second position from the first position, and the linkage ejector rod 181 moves along with the clamping assembly 15 in a direction away from the floating support member 17, so that the linkage ejector rod 181 removes the downward acting force on the floating support member 17, the elastic member 182 is deformed in a restoration manner, and the floating support member 17 is forced to rise to the floating position, thereby realizing linkage driving of the floating support member 17, having a simple structure, and being capable of ensuring reliable switching between the floating position and the sinking position of the floating support member 17.

When the third driving device 16 drives the clamping assembly 15 to return from the first position to the second position, the linkage ejector rod 181 moves away from the floating support 17, so that the inclined driving surface on the linkage ejector rod 181 gradually releases the compression surface S17, and the floating support 17 is restored to the floating position under the action of the elastic member 182.

Advantageously, the open groove H50 is formed in a V shape, and the open groove H50 has two sidewalls, that is, two opposite sides of the first positioning portion 5112 and the second positioning portion 5113 of the open groove H50. The stopping platform 501 further has a first inclined surface S50 and a second inclined surface S51, the stopping surface S52 is located between the first inclined surface S50 and the second inclined surface S51, when the stopping platform 501 is located in the opening H50, the first inclined surface S50 is attached to one of two side walls of the opening H50, and the second inclined surface S51 is attached to the other of two side walls of the opening H50.

Preferably, the extending direction of the blade 5111 is perpendicular to the extending direction of the thread end, and the first positioning portion 5112 is provided with a clearance opening H52 for avoiding the thread end. Generally, after the hitching leg, the extending direction of the hitching leg wire head is perpendicular to the conductive pin 821, and the extending direction of the blade 5111 is also perpendicular to the extending direction of the hitching leg wire head, so that the first positioning portion 5112 easily interferes with the hitching leg wire head, which causes the first positioning portion 5112 to bend the hitching leg wire head, thereby being unfavorable for the wire cutting operation. In order to avoid mechanical interference between the first positioning portion 5112 and the hitching leg wire when the cutter 511 moves toward the stopping table 501, the clearance H52 is provided on the first positioning portion 5112, so that the first positioning portion 5112 and the hitching leg wire do not interfere with each other when the blade 5111 moves to contact with the stopping surface S52, and further the blade 5111 is ensured to reliably cut off the hitching leg wire.

Meanwhile, the driving device drives the two cutters 511 on the same side in the second direction to approach the other two stopping platforms 501 along the second direction, so that the open grooves H50 on the two cutters 511 are respectively engaged with the other two stopping platforms 501 in an inserting manner, and the blade portions 5111 in the two open grooves H50 are respectively abutted against the stopping surfaces S52 on the other two stopping platforms 501, so that the two second hitching leg wire ends 811b are cut off.

Referring to fig. 18 to 20, in one embodiment of the present utility model, the fourth driving device 512 includes a first rotating arm 5121, a second rotating arm 5122, a third rotating arm 5123, a first driver 5124, a second driver 5125 and a third driver 5126, wherein the first rotating arm 5121 and the second rotating arm 5122 are respectively provided at both sides of the positioning seat 50 in the first direction and are pivotable about axes respectively extending in the second direction; one of the two cutters 511 is provided on the first rotating arm 5121, and the other of the two cutters 511 is provided on the second rotating arm 5122. A third rotating arm 5123 is provided at the one side of the positioning seat 50 in the second direction and is pivotable about an axis extending in the first direction, and the other two cutters 511 are provided on the third rotating arm 5123.

The first driver 5124 is connected to the first rotating arm 5121 and is used for driving the first rotating arm 5121 to rotate; the second driver 5125 is connected to the second rotating arm 5122 and is used for driving the second rotating arm 5122 to rotate; the third driver 5126 is connected to the third rotating arm 5123 to drive the third rotating arm 5123 to rotate.

For example, the first driving device 600 may include a plurality of linear modules, for example, the first driving device 600 includes a first linear module driving the thread end cutting device 500 to move along a first direction and a second linear module driving the thread end cutting device to move along a third direction, and the third direction is perpendicular to both the first direction and the second direction. In this way, the positioning seat 50 is driven by the linear modules in multiple directions to keep aligned with the electromagnetic element 800 on the hitching leg device 200, and move towards or away from the electromagnetic element 800, so as to realize loading fit between the positioning seat 50 and the electromagnetic element 800 on the hitching leg mechanism.

The fifth driving device 203 is connected to the clamping arm 201 and the carrier 202, and is configured to drive the clamping arm 201 and the carrier 202 to move relatively to clamp the magnetic core coil 81. A hold down assembly 204 is disposed adjacent the carrier 202 for holding down and securing the insulator mount 82 to the core coil 81.

That is, the clamping arm 201 is disposed opposite to the carrying seat 202, and the clamping arm 201 is disposed above the carrying seat 202, with a clamping gap between the carrying seat 202 and the clamping arm 201, the magnetic core coil 81 wound with the magnetic core coil 81 is moved to the clamping gap between the clamping arm 201 and the carrying seat 202 by the transfer robot 300, and then the clamping arm 201 and the carrying seat 202 are driven to move in directions approaching to each other by the fifth driving device 203, so as to clamp and fix the magnetic core coil 81 in the clamping gap.

In this embodiment, the clamping arm 201 and the carrying seat 202 are used to clamp and fix the magnetic core coil 81, so that the clamping and fixing are reliable, the magnetic core coil 81 is conveniently loaded into the carrier mechanism 20, and the product is conveniently taken out after the hanging leg is completed.

In addition, when the insulating base 82 moves into the carrier mechanism 20 to be combined with the magnetic core coil 81, the insulating base 82 and the magnetic core coil 81 can be kept relatively fixed through the pressing component 204, so that when the wire end 811 is wound around the conductive pin 821 and pulled by the hitching leg manipulator 21 in the hitching leg process of the hitching leg manipulator 21, the insulating base 82 cannot shift, the hitching leg is ensured to be reliable, and the assembling position between the insulating base 82 and the magnetic core coil 81 is accurate and reliable.

Referring to fig. 12 and 14, in one embodiment of the present utility model, the hitching leg device 200 further includes a wire pulling mechanism 22, wherein the wire pulling mechanism 22 is disposed adjacent to the carrier mechanism 20 for pulling the wire end 811 of the magnetic core coil 81 to a predetermined position.

Since the coil 81 on the closed core 80 is rotatable with respect to the leg 801 after the coil 81 is wound, the position of the wire end 811 of the core coil 81 is uncertain when the core is loaded to the carrier mechanism 20, and in order to enable the hitching robot 21 to accurately clamp to the wire end 811, the wire end 811 may be shifted to a predetermined position by the wire shifting mechanism 22 after the core coil 81 is loaded to the carrier mechanism 20. After the wire end 811 is shifted to the predetermined position, the wire end 811 is clamped by the hitching robot 21 and wound onto the conductive pin 821 of the insulating base 82, so as to complete hitching operation, and thus, the hitching operation can be ensured to be more stable and reliable.

The seventh driving device 223 is connected to the two poking members 221, and is configured to drive the two poking members 221 to rotate outwards, so as to poke the wire end 811 to the predetermined position outwards.

It should be noted that, as described above, since the coil 81 can rotate relative to the side posts 801 after the coil 81 on the closed magnetic core 80 is wound, when the two toggle members 221 toggle the wire ends 811 at the lower ends of the two coils 81 to the outside, the coil 81 will rotate, and the wire ends 811 at the upper ends of the two coils 81 will also rotate to the predetermined position, so that it is unnecessary to dispose the other toggle members 221 to toggle the wire ends 811 at the upper ends of the coils 81, thereby simplifying the structure.

In this embodiment, by pulling the wire ends 811 from the inner side of the wire ends 811 to the outer side by the two pulling members 221, it is ensured that the wire ends 811 can be pulled to a predetermined position, and there is no need to configure four pulling members 221, but only two pulling members 221 are needed, so that the four wire ends 811 can reach a desired position.
