A gap is formed between the two coils 81, and the insulating base 82 has a conductive pin 821 and a fitting portion that can be inserted into the gap. In the processing of the electromagnetic component 800, the coil 81 is wound around the two side legs 801 of the closed magnetic core 80, the fitting portion of the insulating base 82 is inserted into the gap between the two coils 81, the insulating base 82 and the magnetic core coil 81 are assembled together, and finally, the four terminals 811 of the two coils 81 are wound around and hung on the four conductive pins 821 of the insulating base 82. In order to ensure reliable electrical connection between the stub 811 and the conductive pin 821, spot welding is required at a position around the stub 811.

The winding hitching leg device comprises a winding device 100, a hitching leg device 200, a transfer manipulator 300 and a first feeding manipulator 400.

Specifically, the winding device 100 is used for winding the coil 81 on two side columns 801 of the closed magnetic core 80 by using a wire to form the magnetic core coil 81.

The hitching apparatus 200 includes a carrier mechanism 20 and a hitching robot 21, and the hitching robot 21 is disposed around the carrier mechanism 20.

The transfer robot 300 is movable between the winding device 100 and the carrier mechanism 20 to transfer the core coil 81 in the winding device 100 to the carrier mechanism 20. The first loading robot 400 is used to move and butt the insulating holder 82 to the core coil 81 on the carrier mechanism 20.

The carrier mechanism 20 is used for relatively fixing the magnetic core coil 81 and the insulating base 82, and the stitch-hanging manipulator 21 is used for clamping the thread end 811 of the magnetic core coil 81 in the carrier mechanism 20 and winding the thread end onto the conductive pin 821 of the insulating base 82 to form the electromagnetic element 800.

In the specific winding process, the winding device 100 is firstly used for winding on the side column 801 of the closed magnetic core 80 to form the coil 81, and after the winding is finished, the closed magnetic core 80 is provided with the coil 81, and the two are combined into the magnetic core coil 81. The magnetic core coil 81 in the winding device 100 is transferred to the carrier mechanism 20 of the hitching leg device 200 by the transfer robot 300, and one of the insulating holders 82 is taken by the first feeding robot 400 and moved to the carrier mechanism 20, so that the insulating holder 82 is assembled on the magnetic core coil 81, and the carrier mechanism 20 can fix the insulating holder 82 and the magnetic core coil 81 relatively.

According to the winding hitching leg device provided by the embodiment of the invention, the winding device 100 is used for winding the coil 81 on the side column 801 of the closed magnetic core 80 to form the magnetic core coil 81, then the transfer manipulator 300 and the first feeding manipulator 400 are matched to load the magnetic core coil 81 into the carrier mechanism 20, the insulating seat 82 is assembled on the magnetic core coil 81, and finally the hitching leg manipulator 21 is used for winding the wire end 811 of the magnetic core coil 81 onto the conductive pin 821 of the insulating seat 82 to complete the hitching leg.

It can be understood that the winding hitching leg device can also comprise a second feeding mechanical arm which is arranged adjacent to the winding device 100, the closed magnetic core 80 is taken out by the second feeding mechanical arm and the closed magnetic core 80 is loaded into the winding device 100, and then the winding device 100 is used for winding on the two side columns 801 of the closed magnetic core 80, so that the closed magnetic core 80 is automatically fed, and the efficiency is improved.

Referring to fig. 1 to 2, in some embodiments of the present invention, the winding hitching apparatus further includes a thread end cutting device 500 and a first driving device 600, wherein the thread end cutting device 500 is used for cutting the hitching thread end on the conductive pin 821 on the electromagnetic element 800; a first driving device 600 is connected to the thread end cutting device 500 for driving the thread end cutting device 500 to move to the hitching apparatus 200 to cut the hitching thread end on the electromagnetic component 800 by the thread end cutting device 500, wherein the excess length portion after the thread end 811 of the magnetic core coil 81 is wound and hitched on the conductive pin 821 is called "hitching thread end".

After the winding and stitch cutting are completed, the first driving device 600 can drive the thread end shearing device 500 to move to the stitch cutting device 200, and then the thread end shearing device 500 shears the stitch cutting thread end of the electromagnetic element 800 on the carrier mechanism 20, so that the continuous automatic operation of the winding, stitch cutting and thread cutting is realized, the efficiency is higher, and the subsequent manual thread end shearing is not needed.

Referring to fig. 3 to 9, in some embodiments of the present invention, the winding device 100 includes a winding base 10, a cover plate 11 and a second driving device 12, wherein a top surface of the winding base 10 is provided with a station slot H10, a winding slot H112 and a wire guiding slot H111, the station slot H10 is suitable for the closed magnetic core 80 to be inserted upright, the winding slot H112 is formed in a circular arc shape and is wound outside the station slot H10, and the wire guiding slot H111 is connected and communicated with the winding slot H112 to form a winding channel H11. In the example of fig. 1, the bobbin case 10 includes a base 10a and an upper case 10 b.

Preferably, the circle center of the circular arc-shaped winding slot H112 is located on the axis of the side column 801, and the station slot H10 has an arc-shaped edge surrounding the outside of the side column 801, and the winding slot H112 extends along the outside of the arc-shaped edge. 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 application, the wire feeding mechanism 700 is disposed on one side of the winding device 100, and the wire, typically an enameled wire, is fed into the winding passage H11 by the wire feeding mechanism 700. The wire can move along the winding channel H11, i.e., from the wire guide groove H111 to the winding groove H112, and after passing through the wire outlet end of the winding groove H112, the wire can be bent and wound on the side pole 801 of the closed magnetic core 80 to form the coil 81.

The cover plate 11 is slidably disposed on the winding base 10. The second driving device 12 is connected to the cover plate 11 for driving the cover plate 11 to slide to close or open the winding passage H11. Preferably, a thin covering sheet 111 is disposed on the cover plate 11 at a position opposite to the winding slot H112, and the covering sheet 111 extends along the winding slot H112 and covers over the winding slot H112 to close the winding slot H112.

A wire cutting assembly is disposed adjacent to the winding base 10 for cutting the wire to separate the coil 81 after the winding is completed.

That is, the second driving device 12 can drive the cover plate 11 to slide on the winding seat 10, so as to close the wire guiding groove H111 and the winding groove H112, or open the wire guiding groove H111 and the winding groove H112, so as to ensure that the wire is conveyed along the winding channel H11 when the wire guiding groove H111 and the winding groove H112 are closed, and thus ensure smooth winding. After the winding is completed, the wire between the wire feeding mechanism 700 and the winding seat 10 may be cut off by the wire cutting assembly, and at this time, the coil 81 may be separated from the wire. When the cover plate 11 is driven by the second driving device 12 to open the wire guide H111 and the winding slot H112, the core coil 81 can be taken out of the station slot H10 or the closed core 80 can be loaded 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 cover plate 11 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 stably and reliably winding the wire on the closed magnetic core 80, and on the other hand, the wound magnetic core coil 81 can be conveniently taken out from the station slot H10.

Illustratively, the wire cutting assembly comprises a wire cutting seat 13 and a ninth driving device 14, the wire cutting seat 13 is arranged to abut against the wire winding seat 10, and a wire feeding channel communicated with the wire inlet end of the wire winding channel H11 is arranged in the wire cutting seat 13; the ninth driving device 14 is connected to the winding device 100 for driving the winding device 100 to move and displace relative to the wire cutting seat 13, so that the wire is cut at the wire cutting seat 13.

After the winding is completed, the winding device 100 driven by the ninth driving device 14 moves relative to the wire cutting base 13 to be displaced (e.g., moves upward) so that the wire is cut at the wire cutting base 13, so that the coil 81 can form a terminal end after the wire is cut, and the winding channel H11 is opened through the cover plate 11, so that the wound magnetic core coil 81 can be taken out, and thus, the wire end 811 can be formed at the terminal end and the product can be conveniently separated.

Referring to fig. 3 to 9, in an embodiment of the present invention, a sidewall 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, wherein 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. A third drive means 16 is connected to the gripping assembly 15 for driving the gripping assembly 15 between the first and second positions.

When the clamping member 15 is located at the first position, the clamping member 15 is located in the opening H101 and close to the station groove H10, so as to clamp the start end of the coil 81 by the clamping member 15, and when the clamping member 15 moves from the first position to the second position, the clamping member 15 moves in the opening H101 in a direction away from the station groove H10, so as to elongate the start end to form a wire head 811.

That is, the clamping assembly 15 can perform an opening or closing action to clamp or release the starting 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 clamping assembly 15 can be used for pulling the starting end of the coil 81 to form the thread end 811.

In the specific winding process, in the initial state, the clamping assembly 15 is located at the second position, the closed magnetic core 80 is vertically inserted into the station slot H10, the wire is fed into the winding channel H11 through the wire feeding mechanism 700, the wire is output through the wire outlet end of the winding channel H11 and then is wound on the side column 801 of the closed magnetic core 80, preferably, the wire feeding can be stopped when the wire is not completely wound on the side column 801, for example, the wire feeding is stopped after the wire is wound for the first circle, at this time, the clamping assembly 15 is driven by the third driving device 16 to move from the second position to the first position, that is, the clamping assembly 15 moves into the notch H101 and approaches the station slot H10, the clamping assembly 15 is closed to clamp the starting end of the wire on the side column 801, then, the clamping assembly 15 is driven by the third driving device 16 to move from the first position to the second position, so that the clamping assembly 15 clamps the starting end of the wire and pulls the starting end of the wire outwards for a certain distance to form a wire end 811, then, the holding member 15 releases the starting end of the wire, the wire feeding mechanism 700 continues to feed the wire, and the wire is continuously wound on the side pole 801 through the winding passage H11 to form the coil 81 composed of a plurality of turns of the wire.

It should be noted that, if the pulling action of the clamping assembly 15 is used 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 is not too long, so as to ensure that the head 811 formed after pulling can still pass through between the two side columns 801 of the closed magnetic core 80, and further, in the subsequent wire feeding process, the head 811 cannot be blocked by the other side column 801 on the opposite side, but passes through the gap between the two side columns 801, and is continuously wound on the side columns 801, thereby completing the winding of the coil 81.

In this embodiment, the clamping assembly 15 is disposed at the opening H101 of the winding seat 10, the clamping assembly 15 is driven by the third driving device 16 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 stub 811.

Referring to fig. 4 to 5 and 7 to 9, in an embodiment of the present invention, the winding device 100 further includes a floating support 17 and a linkage 18, wherein the floating support 17 is disposed at the bottom of the station slot H10 to support the closed magnetic core 80, and when the closed magnetic core 80 is inserted into the station slot H10, the bottom of the closed magnetic core 80 contacts the floating support 17, and the closed magnetic core 80 is supported by the floating support 17.

A linkage 18 is provided between the clamping 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 clamping assembly 15.

When the clamping assembly 15 is located at the second position, the linkage member 18 forces the floating support 17 to be at the floating position, so that the outlet end of the winding passage H11 is opposite to the lower end of the side column 801 of the closed magnetic core 80; when the clamping assembly 15 moves from the second position to the first position, the link member 18 forces the floating support member 17 to descend to the depressed position, so that the outlet end of the winding passage H11 is opposite to the middle position of the side pole 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 as to raise and lower the closed magnetic core 80.

In the particular winding process, in the initial state, the clamping assembly 15 is in the second position, in which the floating support 17 is in the floating position, and correspondingly, the outlet end of the winding passage H11 is opposite to the lower end of the side column 801 enclosing the magnetic core 80. The wire feeding mechanism 700 is used for feeding wires into the winding channel H11, the wire can be wound on the side column 801 of the closed magnetic core 80 from bottom to top after being output through the wire outlet end of the winding channel H11, the wire feeding is stopped after the wire is wound on the side column 801 for a certain number of turns (for example, wound for a first turn), the third driving device 16 drives the clamping assembly 15 to move from the second position to the first position, and the clamping assembly 15 moves into the notch H101 and is close to the station groove H10.

At the same time, the link 18 drives the floating support 17 to move downwards to the sinking position, the closed magnetic core 80 supported by the floating support 17 descends, 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, correspondingly, the first winding coil 81 is located at the middle position of the side column 801, and when the position is closed by the clamping assembly 15, the starting end of the wire on the side column 801 can be clamped.

Then, the clamping assembly 15 is driven by the third driving device 16 to move from the first position to the second position, so that the clamping assembly 15 clamps the starting end of the wire and pulls the starting end of the wire outward for a certain distance to form a wire head 811, and the clamping assembly 15 releases the starting end of the wire. In the process, the linkage member 18 moves along with the clamping assembly 15 to drive the floating support member 17 to return to the floating position, i.e. the outlet end of the winding channel H11 is opposite to the lower end of the side pillar 801 of the closed magnetic core 80, and correspondingly, the wound first coil 81 returns to the lower end position of the side pillar 801. The wire feeding mechanism 700 continues to feed the wire, and the wire is continuously wound around the side pole 801 through the winding passage H11 to form the coil 81 formed by 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 through the linkage of the linkage 18, so that when the start end of the coil 81 needs to be pulled by the clamping assembly 15, the floating support 17 can be switched to the sinking position, and the coil 81 in the first turn is kept at the middle position of the side column 801, so that when the clamping assembly 15 is close to the closed magnetic core 80, the interference with the closed magnetic core 80 is avoided, the start end of the wire rod can be directly inserted into the hole of the closed magnetic core 80 to be clamped, in other words, the start end of the wire rod can be reliably clamped without mechanical interference in a minimum space by the clamping assembly 15. And after drawing and forming end of a thread 811, can make floating support member 17 resume to the come-up position, the first circle coil 81 of coiling resumes to the lower extreme position of side post 801, and then can continue to accomplish follow-up wire winding, and its simple structure, linkage design benefit ensures that end of a thread 811 is drawn and the wire winding is stable orderly.

Referring to fig. 7 to 9, in an embodiment of the present invention, the linkage member 18 includes an elastic member 182 and a linkage rod 181, wherein the elastic member 182 is disposed in the station groove H10, a lower end of the elastic member 182 abuts against a bottom wall of the station groove H10, and an upper end of the elastic member 182 abuts against the floating support 17.

One end of the linkage ejector rod 181 is connected to the clamping assembly 15, the other end of the linkage ejector rod 181 is in linkage fit with the floating support 17, and when the clamping assembly 15 moves from the second position to the first position, the other end of the linkage member 18 forces the floating support 17 to descend to the sinking position against the elastic force of the elastic member 182.

That is, when the clamping assembly 15 is at the second position, the clamping assembly 15 is forced to be kept at the floating position toward the floating support 17 under 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 rod 181 to move toward the floating support 17, and the linkage rod 181 generates a downward force on the floating support 17, so that the floating support 17 is forced to fall to the sinking position against the elastic force of the elastic member 182. In addition, after the clamping assembly 15 clamps the starting end of the wire, in the process that the third driving device 16 drives the clamping member to return to the second position from the first position, the linkage ejector rod 181 moves along with the clamping assembly 15 in the direction away from the floating support member 17, so that the linkage ejector rod 181 cancels the downward acting force on the floating support member 17, the elastic member 182 recovers deformation, and the floating support member 17 is forced to rise to the floating position, thereby realizing the linkage driving of the floating support member 17, having a simple structure, and ensuring that the floating support member 17 can be reliably switched between the floating position and the sinking position.

That is, when the third driving device 16 drives the clamping assembly 15 to move from the second position to the first position, the linkage ejector 181 moves in a direction approaching the floating support 17, and the inclined driving surface on the linkage ejector 181 generates a downward pressure on the pressure receiving surface S17 on the floating support 17, thereby lowering the floating support 17 to the sinking position. 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, and the inclined driving surface on the linkage ejector rod 181 gradually releases the pressure receiving surface S17, so that the floating support 17 returns to the floating position under the action of the elastic member 182.

In this embodiment, the linkage ejector rod 181 slides in the opening H17 of the floating support member 17, and the linkage ejector rod 181 can press the floating support member 17 down to the sinking position by the cooperation between the inclined pressing surface on the linkage ejector rod 181 and the pressure receiving surface S17 on the floating support member 17, so that the structure is simple, and the linkage is reliable and stable.

In addition, the closed magnetic core 80 is not easily separated from the station slot H10, and stability in winding is maintained.

The positioning socket 50 has a stopping platform 501, and the stopping platform 501 has a stopping surface S52, so that when the positioning socket 50 positions the electromagnetic element 800, the stitch stub is close to the stopping surface S52.

Referring to fig. 20, in an embodiment of the present invention, the insulating base 82 has a protrusion extending in the same direction as the conductive pin 821, and the protrusion generally functions as a support isolation from the circuit board, that is, when the electromagnetic component 800 is applied to a specific product, the protrusion contacts with the circuit board when the insulating base 82 is plugged onto the circuit board, so that a gap is formed between the electromagnetic component 800 and the circuit board. The positioning seat 50 is provided with a positioning opening H50 matched with the protruding portion.

In this embodiment, the positioning opening H50 on the positioning seat 50 and engaged with the protrusion portion can make the protrusion portion just block in the positioning opening H50 when the positioning seat 50 is engaged with the electromagnetic element 800, so that the positioning seat 50 and the electromagnetic element 800 can be relatively fixed by the engagement of the protrusion portion and the positioning opening H50.

Referring to fig. 20 to 24, in an embodiment of the present invention, the cutter 511 includes a blade portion 5111, a first positioning portion 5112 and a second positioning portion 5113, wherein the blade portion 5111 is used for cutting the hitching leg head, and preferably, the blade portion 5111 is opposite to the stop surface S52.

The first positioning portion 5112 and the second positioning portion 5113 are oppositely arranged, and an open slot H50 is defined between the first positioning portion and the second positioning portion, and the open slot H50 is adapted to the stopping platform 501. The blade portion 5111 is provided in the open groove H50 and extends in parallel. When the fourth driving device 512 drives the cutter 511 to move to a predetermined position, the stopping platform 501 is located in the opening groove H50, and the blade abuts against the stopping surface S52 to cut off the head of the hitching leg.

In this embodiment, the first positioning portion 5112 and the second positioning portion 5113 define an open slot H50, and the blade portion 5111 is disposed in the open slot H50 and extends in parallel, so that when the first driving device 600 drives the cutting blade 511 to move toward the stopping table 501, the stopping table 501 is inserted into the open slot H50, and the cutting blade 511 and the stopping table 501 can be engaged with each other, the movement of the cutting blade 511 is reliable, and the cutting blade portion 5111 can accurately and reliably cut off the thread end of the hitching leg on the stopping surface S52.

Advantageously, the open groove H50 is formed in a V shape, and the open groove H50 has two side walls, that is, two opposite side surfaces on the first positioning portion 5112 and the second positioning portion 5113, of the open groove H50. The stopping table 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 table 501 is located in the open slot H50, the first inclined surface S50 is attached to one of the two side walls of the open slot H50, and the second inclined surface S51 is attached to the other of the two side walls of the open slot H50.

That is, the first inclined surface S50 and the second inclined surface S51 on the stop 501 correspond to two sidewalls of the opening groove H50, respectively, and an included angle formed between the first inclined surface S50 and the second inclined surface S51 is matched with the opening groove H50. When the first driving device 600 drives the cutter 511 to move towards the stopping table 501, two side walls of the opening groove H50 interact with the first inclined surface S50 and the second inclined surface S51 on the stopping table 501 to play a guiding role, so as to guide the stopping table 501 to be accurately inserted into the opening groove H50, and further, the blade portion 5111 accurately and reliably cuts off the thread end of the hitching leg on the stopping surface S52, thereby ensuring that the thread cutting is more stable and reliable.

It is more advantageous that the knife edge portion 5111 has a predetermined distance to the opening of the open slot H50, that is, the knife edge portion 5111 is hidden in the open slot H50, so that the guide engagement between the open slot H50 and the stop 501 can ensure that the knife edge can accurately move toward the stop surface S52.

Referring to fig. 21 to 22, in an embodiment of the present invention, a clearance H51 is defined between the blade portion 5111 and the second positioning portion 5113 to clearance the conductive pin 821 of the insulating base 82. Since the insulating base 82 has the conductive pin 821, and when the electromagnetic element 800 is assembled and matched with the positioning base 50, the head of the hitching leg on the electromagnetic element 800 is close to the stopping surface S52 and opposite to the knife edge portion 5111, in this embodiment, a clearance groove H51 is defined between the knife edge portion 5111 and the second positioning portion 5113, and when the stopping platform 501 is inserted into the opening groove H50, the conductive pin 821 is just located in the clearance groove H51, so as to avoid the mechanical interference between the conductive pin 821 and the cutter 511, and ensure that the knife edge portion 5111 can abut against the stopping surface S52 to cut off the head of the hitching leg on the conductive pin 821.

Preferably, the extending direction of the blade portion 5111 is perpendicular to the extending direction of the thread end, and the first positioning portion 5112 is provided with a clearance avoiding opening H52 for avoiding the thread end. Generally, after hitching, the extension direction of the hitching leg stub is perpendicular to the conductive pin 821, and the extension direction of the knife edge part 5111 is also perpendicular to the extension direction of the hitching leg stub, so the first positioning part 5112 is easily interfered with the hitching leg stub, and the hitching leg stub is bent by the first positioning part 5112, which is not beneficial to the thread cutting operation. In order to avoid mechanical interference between the first positioning portion 5112 and the hitching leg wire end when the cutter 511 moves toward the stopper 501, the clearance H52 is provided in the first positioning portion 5112, so that the first positioning portion 5112 does not interfere with the hitching leg wire end when the cutter edge portion 5111 moves to abut against the stopper surface S52, thereby ensuring that the cutter edge portion 5111 can reliably cut the hitching leg wire end.

Illustratively, the electromagnetic element 800 has two first stitch stubs 811a and two second stitch stubs 811b, which are arranged opposite in the first direction and extend in the second direction; the two second wire hanging wire ends extend towards opposite directions on the same straight line and in the first direction.

Correspondingly, there are four stopping tables 501, two of the four stopping tables 501 are respectively located at two sides of the positioning seat 50 in the first direction, and the other two of the four stopping tables 501 are located at the same side of the positioning seat 50 in the second direction.

Four cutters 511 are provided, two of the four cutters 511 are respectively located at two sides of the positioning seat 50 in the first direction, and correspond to the two stopping tables 501 one by one, and the open grooves H50 of the two cutters 511 are opposite to each other in the first direction; the other two of the four cutters 511 are located on the same side of the positioning seat 50 in the second direction and correspond to the other two stopping platforms 501 one by one, and the open grooves H50 of the other two cutters 511 face the same side in the second direction.

In the stitch stub cutting operation, the fourth driving device 512 drives the two cutters 511 in the first direction to move in the direction in which the two cutters 511 approach relatively in the first direction, so that the open grooves H50 on the two cutters 511 are respectively inserted into and engaged with the two stop platforms 501 in the first direction, and thus the blade portions 5111 in the two open grooves H50 respectively abut against the stop surfaces S52 on the two stop platforms 501, and further cut off the two first stitch stubs 811 a. Meanwhile, the driving device drives the two cutters 511 on the same side in the second direction to approach the other two stop platforms 501 along the second direction, so that the open grooves H50 on the two cutters 511 are respectively inserted and engaged with the other two stop platforms 501, and thus the blade parts 5111 in the two open grooves H50 respectively abut against the stop surfaces S52 on the other two stop platforms 501, and further cut off the two second hitching leg wire ends 811 b.

In this embodiment, the four cutters 511 and the four stoppers 501 cooperate with each other, so that the two first stitch stubs 811a and the two second stitch stubs 811b can be cut off at a time, the efficiency is high, and the trimming operation of the electromagnetic element 800 having four stitch stubs, such as the common mode inductor, can be performed.

Referring to fig. 18 to 20, in an embodiment of the present invention, 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 disposed at two sides of the positioning seat 50 in the first direction and are pivotable around axes respectively extending along the second direction; one of the two cutting blades 511 is provided on the first rotary arm 5121, and the other of the two cutting blades 511 is provided on the second rotary arm 5122. A third rotating arm 5123 is disposed on the side of the positioning seat 50 in the second direction and is pivotable about an axis extending along the first direction, and the other two cutting knives 511 are disposed on the third rotating arm 5123.

A first driver 5124 is connected to the first rotation arm 5121 to drive the first rotation arm 5121 to rotate; the second driver 5125 is connected to the second rotary arm 5122 to drive the second rotary arm 5122 to rotate; the third driver 5126 is connected to the third rotary arm 5123 to drive the third rotary arm 5123 to rotate.

In the stitch thread end cutting operation, the first driver 5124, the second driver 5125 and the third driver 5126 may simultaneously operate to respectively drive the first rotary arm 5121, the second rotary arm 5122 and the third rotary arm 5123 to rotate in the direction close to the positioning seat 50, so that the two first stitch thread ends 811a and the two second stitch thread ends 811b are respectively cut off by the cutters 511 on the first rotary arm 5121, the second rotary arm 5122 and the third rotary arm 5123, thereby completing the one-time stitch cutting operation.

For example, the first driving device 600 may include linear modules with multiple directions, for example, the first driving device 600 includes a first linear module for driving the thread end cutting device 500 to move along a first direction and a second linear module for driving the thread end cutting device 500 to move along a third direction, which is perpendicular to the first direction and the second direction. Thus, 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 the direction close to or away from the electromagnetic element 800, so that the loading and matching of the positioning seat 50 and the electromagnetic element 800 on the hitching leg mechanism are realized.

Referring to fig. 12, 14 to 15, in some embodiments of the present invention, the carrier mechanism 20 includes a clamping arm 201, a carrying seat 202, a fifth driving device 203, and a pressing assembly 204, wherein a clamping gap suitable for carrying the core coil 81 is defined between the carrying seat 202 and the clamping arm 201. The fifth driving device 203 is connected to the clamping arm 201 and the carrying seat 202, and is used for driving the clamping arm 201 and the carrying seat 202 to move relatively to clamp the magnetic core coil 81. A compression assembly 204 is disposed adjacent to the carrier 202 for compressing and fixing the insulator 82 to the core coil 81.

That is, the holding arm 201 is disposed opposite to the carrier 202, for example, the holding arm 201 is disposed above the carrier 202, a holding gap is formed between the carrier 202 and the holding arm 201, the transfer robot 300 moves the magnetic core coil 81 wound around the holding arm 201 to the holding gap between the holding arm 201 and the carrier 202, and the fifth driving device 203 drives the holding arm 201 and the carrier 202 to move in directions close to each other, so as to clamp and fix the magnetic core coil 81 in the holding gap.

In this embodiment, the magnetic core coil 81 is clamped and fixed by the relative movement of the clamping arm 201 and the carrying seat 202, which is reliable in clamping and fixing, and facilitates the loading of the magnetic core coil 81 into the carrying mechanism 20 and the taking out of the product after the completion of the hitching leg.

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 hitching robot 21 hooks the wire end 811 around the conductive pin 821 and pulls the wire end, the insulating base 82 does not shift, thereby ensuring that the hitching is 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 an embodiment of the present invention, the hitching apparatus 200 further includes a wire-pulling mechanism 22, and the wire-pulling mechanism 22 is disposed adjacent to the carrier mechanism 20 and used for pulling the wire end 811 on the magnetic core coil 81 to a predetermined position.

Since the coil 81 can be rotated with respect to the side pole 801 after the coil 81 on the closed magnetic core 80 is wound, the position of the stub 811 of the magnetic core coil 81 is uncertain when the magnetic core is loaded on the carrier mechanism 20, and in order to allow the stitch placing robot 21 to accurately grip the stub 811, the stub 811 can be shifted to a predetermined position by the thread pulling mechanism 22 after the magnetic core coil 81 is loaded on the carrier mechanism 20. After the wire end 811 is shifted to a predetermined position, the wire end 811 is clamped by the hitching arm 21 and wound onto the conductive pin 821 of the insulating base 82 to complete the hitching operation, so that the hitching operation is more stable and reliable.

Referring to fig. 14, in an embodiment of the present invention, the wire-pulling mechanism 22 includes two pulling members 221, a sixth driving device 222 and a seventh driving device 223, wherein the two pulling members 221 correspond to the two coils 81 and are respectively used for pulling the wire ends 811 at one end of the two coils 81.

The sixth driving device 222 is connected to the two toggle members 221, and is configured to drive the two toggle members 221 to move to the vicinity of the carrier mechanism 20, so that the two toggle members 221 are located inside the thread ends 811 at one end of the two coils 81. The seventh driving device 223 is connected to the two toggle parts 221, and is configured to drive the two toggle parts 221 to rotate outward, so as to toggle the thread end 811 to the predetermined position outward.

After the core coil 81 is loaded on the carrier mechanism 20 and fixed, the two shifting members 221 are driven by the sixth driving device 222 to move in a direction approaching the carrier mechanism 20, in the example of fig. 1, the sixth driving device 222 drives the two shifting members 221 to move upwards to extend into the inner sides of the stubs 811 at the lower ends of the two coils 81, and after the two shifting members 221 move into the inner sides of the stubs 811 of the two coils 81, the seventh driving device 223 drives the two shifting members 221 to move outwards, so that the two shifting members 221 can shift the stubs 811 at the lower ends of the coils 81 to a predetermined position.

It should be noted that, as described above, after the coil 81 on the closed magnetic core 80 is wound, the coil 81 can rotate relative to the side pole 801, so when the two dialing members 221 dial the stubs 811 at the lower ends of the two coils 81 to the outside, the coil 81 rotates, and further the stubs 811 at the upper ends of the two coils 81 rotate to a predetermined position, so that it is not necessary to dispose another dialing member 221 to dial the stubs 811 at the upper ends of the coil 81, and the structure is simplified.

In this embodiment, the two dialing members 221 dial the stub 811 from the inner side of the stub 811 to the outer side, so that the stub 811 can be ensured to be shifted to a predetermined position, and the four dialing members 221 are not required to be configured, but only the two dialing members 221 are required, so that the four stubs 811 can all reach the required position.

Referring to fig. 14, in some embodiments of the present invention, the pressing assembly 204 includes two rotating pressing members 2041 and two fourth drivers 2042, the two rotating pressing members 2041 are respectively located at two sides of the bearing seat 202, each rotating pressing member 2041 has a first arm 2041a and a second arm 2041b, one end of the first arm 2041a is connected to one end of the second arm 2041b to form a predetermined included angle, and the other end of the second arm 2041b is provided with a pressing portion.

The two fourth drivers 2042 correspond to the two rotary pressing pieces 2041 one by one, and each fourth driver 2042 is connected to the other end of the first arm 2041a of the corresponding rotary pressing piece 2041; when the fourth driver 2042 drives the rotary pressing member 2041 to rotate, the pressing portion presses the edge of the insulating base 82.

After the insulating base 82 and the magnetic core coil 81 are loaded and matched, the fourth driver 2042 drives the first arm 2041a, so that the rotating pressing member 2041 rotates, and the pressing portion of the second arm 2041b moves towards the direction close to the insulating base 82, so as to press the edge of the insulating base 82, so that the two rotating pressing members 2041 can press the edges of the left side and the right side of the insulating base 82, and the insulating base 82 and the magnetic core are pressed and fixed.

Referring to fig. 15, in an embodiment of the present invention, the closed magnetic core 80 further includes a first closed portion 802 and a second closed portion 803, the first closed portion 802 is connected between one ends of the two side legs 801, and the second closed portion 803 is connected between the other ends of the two side legs 801.

Correspondingly, a first positioning groove H20 is formed in the carrying seat 202 for positioning the first sealing portion 802, and a second positioning groove H21 is formed in the clamping arm 201 for positioning the second sealing portion 803. In the example of fig. 6, the first and second seating grooves H20 and H21 are opened toward one side in a horizontal direction.

The first closing part 802 of the closed magnetic core 80 abuts against the first positioning groove H20 on the bearing seat 202, and the second closing part 803 of the closed magnetic core 80 abuts against the second positioning groove H21 on the bearing seat 202, so that the magnetic core coil 81 can be reliably fixed, the position can not deviate, and the like, and the operation of the hanging pin is more reliable and stable.
