Description

Technical Field

[0001] The present invention relates to the field of stator manufacturing, and particularly to a fully automatic winding machine for stator assemblies. Background Art

[0002] A stator winding machine is a key device in the motor manufacturing industry. It is mainly used for winding coils on the stator core of a motor. Its application range is extremely wide. For example, it is used in the winding of stator coils of motors in automobile manufacturing, home appliance motors, power tool motors, and small motors in aerospace equipment, greatly improving the production efficiency and quality of motor stator coils.

[0003] For the stator winding process, generally, a row winding machine winds on a long strip mold and then demolds. After that, multiple people perform wire splitting operations. After splitting into multiple series-connected coils, they are individually hung on special wire forks; after the wire-winding personnel send the coils on the wire forks into the wire-inserting tooling, the wire forks flow back to the wire splitting and coil hanging for recycling.

[0004] In the prior art, wire splitting and hanging are usually carried out manually, winding the wire on a specific mold, which is cumbersome and inefficient. Moreover, a wire-inserting process requires multiple people to split and hang wires together, with low efficiency; manual wire splitting will also affect the product quality due to manual operation errors. Summary of the Invention

[0005] To facilitate the winding of coils, the present application provides a fully automatic winding machine for stator assemblies.

[0006] The fully automatic winding machine for stator assemblies provided by the present application adopts the following technical solutions: A fully automatic winding machine for stator assemblies includes a frame, a driving mechanism, a winding mechanism, and a wire pushing and cutting mechanism. A plurality of rotating shafts are rotatably connected to the frame, and a plurality of winding claws are respectively rotatably connected to the plurality of rotating shafts. The driving mechanism is used to respectively drive the rotation of the plurality of rotating shafts and the plurality of winding claws. When the driving mechanism drives the plurality of winding claws to rotate perpendicular to the axis of the rotating shaft, the winding mechanism is used to wind copper wires around the plurality of winding claws respectively. A plurality of groups of wire-inserting molds are detachably connected to the frame, and the plurality of groups of wire-inserting molds respectively correspond to the plurality of rotating shafts. When the driving mechanism drives the plurality of winding claws to rotate parallel to the axis of the rotating shaft, the wire pushing and cutting mechanism is used to push the coils wound around the winding claws into the corresponding wire-inserting molds and cut the copper wires from the winding claws.

[0007] By adopting the above technical solution, first, the driving mechanism is used to drive multiple wire winding claws to rotate simultaneously to a direction perpendicular to the axis of the rotating shaft, and then the wire winding mechanism winds the copper wires around the wire winding claws respectively. After any one of the wire winding claws is wound, the driving mechanism drives the rotating shaft to rotate, turns different wire winding claws towards the wire winding mechanism and winds the wires. After all the wire winding claws are wound, the driving mechanism drives the multiple wire winding claws to rotate to a direction parallel to the axis of the rotating shaft. Finally, the pushing and cutting mechanism pushes the coils wound on the wire winding claws into the corresponding wire embedding molds and cuts the copper wires from the wire winding claws; it is convenient for mass production, facilitates batch processing of multiple stator windings with the same specifications, improves production efficiency, can keep the copper wire windings in a preset shape, improves the winding quality, ensures the integrity and insulation performance of the windings, and reduces the probability of failures occurring during the equipment operation to the motor.

[0008] Preferably, the driving mechanism includes a first driving component, which is used to drive the simultaneous rotation of multiple wire winding claws. The first driving component includes a first cylinder, a push-pull plate and several sliding disks. The push-pull plate is slidably connected to the frame along the axis direction of the rotating shaft. The push-pull plate is provided with several clamping rods. Several of the sliding disks respectively correspond to several rotating shafts, and several of the sliding disks are coaxially and slidably connected to the corresponding rotating shafts. The inner circumferential surfaces of several of the sliding disks are respectively provided with chutes. Several of the clamping rods are respectively slidably connected to the corresponding sliding disks around the bottom surfaces of the corresponding sliding disks. Multiple hinge rods are respectively hingedly connected to multiple wire winding claws, and the ends of multiple hinge rods away from the wire winding claws are respectively hingedly connected to the corresponding sliding disks. The first cylinder is fixedly connected to the frame, and one end of the piston rod of the first cylinder is fixedly connected to the push-pull plate.

[0009] By adopting the above technical solution, according to the principle of the four-bar hinge, when the sliding disk moves towards the wire winding claw side, the wire winding claw rotates towards the wire embedding mold side to a direction parallel to the axis of the rotating shaft and abuts against the wire embedding mold. When the sliding disk moves towards the side away from the wire winding claw, the wire winding claw rotates towards the side away from the wire embedding mold to a direction perpendicular to the axis of the rotating shaft; by setting the clamping rods and making the clamping rods slidably connected to the chutes on the inner circumferential surface of the sliding disk, the movement and rotation of several sliding disks are not interfered; through the piston movement of the piston rod of the first cylinder, the push-pull plate drives multiple sliding disks to reciprocate along the axis direction of the rotating shaft, so that the wire winding claws on several rotating shafts move simultaneously, reducing the possibility of different wire groups wound on different rotating shafts having different shapes, and at the same time reducing the possibility of the wound copper wires being damaged by accidental extrusion, collision, etc., ensuring the integrity and insulation performance of the windings.

[0010] Preferably, the driving mechanism also includes a second driving component, which is used to drive the rotation of several rotating shafts at the same time. The second driving component includes several second synchronous wheels, a second synchronous belt and a second motor. The several second synchronous wheels correspond to several rotating shafts respectively, and the several second synchronous wheels are coaxially and fixedly connected to the corresponding rotating shafts. The second synchronous belt is simultaneously wound around and meshedly connected to the several second synchronous wheels. The second motor is fixedly connected to the frame, and one end of the output shaft of the second motor is coaxially and fixedly connected to any second synchronous wheel.

[0011] By adopting the above technical solution, the second motor drives any second synchronous wheel to rotate, and the second synchronous belt is simultaneously wound and meshedly connected to several second synchronous wheels, so that several second synchronous wheels rotate at the same time, thereby driving multiple rotating shafts to rotate at the same time, so that the rotation of several rotating shafts remains consistent, which is convenient for mass production and reduces the possibility of different shapes of wire groups wound on different rotating shafts. At the same time, it reduces the possibility of the wound copper wire being damaged by accidental extrusion, collision, etc., and ensures the integrity and insulation performance of the winding.

[0012] Preferably, the winding mechanism includes a plurality of winding rods, a plurality of groups of guide wheels and a fourth driving assembly, a plurality of bobbins with copper wire wound thereon are arranged next to the frame, a plurality of groups of guide wheels are rotatably connected to the frame, a plurality of winding rods are rotatably connected to the frame, a plurality of winding rods correspond to a plurality of groups of guide wheels and a plurality of bobbins, respectively, the copper wires on a plurality of bobbins are respectively passed around corresponding guide wheels and passed through corresponding winding rods, and the fourth driving assembly is used to drive a plurality of winding rods to rotate simultaneously.

[0013] By adopting the above technical solution, the fourth driving component simultaneously drives the rotation of several winding rods, so that the guides passed through the several winding rods are respectively wound on multiple winding claws, and by setting several groups of guide wheels, the copper wire on the bobbin is guided to move the wire on the bobbin from the bobbin to the winding rod; the rotation of several winding rods is kept consistent, which is convenient for mass production and reduces the possibility of different shapes of wire groups wound on different rotating shafts.

[0014] Preferably, the wire-pushing mechanism includes several groups of inserts, several scissors, and a third driving component. The several groups of inserts respectively correspond to several rotating shafts. The several groups of inserts are respectively slidably connected to the rotating shafts along the axial directions of the corresponding rotating shafts. Each group of inserts includes a plurality of inserts, and the plurality of inserts are located between two adjacent wire-winding claws. The several scissors respectively correspond to the several rotating shafts. The several scissors are respectively slidably connected to the machine frame along the axial directions of the corresponding rotating shafts. Springs are provided on the two sides of the handles of the several scissors, and the springs always drive the two sides of the handles to rotate towards the opposite sides. A plurality of guide rails are provided on the machine frame, and the several guide rails respectively correspond to the several scissors. The several guide rails are respectively fixedly connected to the machine frame. One end of the several guide rails close to the wire-inserting mold to the end far from the wire-inserting mold is arranged in a gradually expanding shape. The opposite sides of the two cutting heads of the several scissors respectively abut against the two side surfaces of the guide rails. The third driving component is used to drive the movement of the several groups of inserts and the several scissors simultaneously.

[0015] By adopting the above technical solution, during the process that the third driving component drives the scissors and the inserts to slide towards the wire-inserting mold side, the inserts push the coil wound around the wire-winding claws and embed it into the wire-inserting mold, which can keep the copper wire winding in a preset shape. The slide rail makes the cutting head part of the scissors rotate towards the opposite side to cut the copper wire, so that the coil is cut while being embedded into the wire-inserting mold, reducing the possibility of the coil spreading; during the process that the scissors slide towards the side far from the wire-inserting mold, the springs drive the two sides of the handles to rotate towards the opposite sides, so that the two cutting head parts of the scissors rotate towards the opposite sides, and the inserts are reset at the same time.

[0016] Preferably, the third driving component includes a connecting plate, several limiting rods, and a third air cylinder. The plate is slidably connected to the machine frame along the axial direction of the rotating shaft. The several limiting rods are respectively fixedly connected to the connecting plate. Fixed rings are respectively rotatably connected to the several limiting rods. The several groups of inserts are respectively fixedly connected to the corresponding fixed rings, and the rotating shafts of the several scissors are respectively fixedly connected to the connecting plate. The third air cylinder is fixedly connected to the machine frame, and one end of the piston rod of the third air cylinder is fixedly connected to the connecting plate.

[0017] By adopting the above technical solution, through the piston movement of the piston rod of the third air cylinder, the connecting plate makes a reciprocating movement on the machine frame, so that the limiting rods and the fixed rings rotatably connected to the limiting rods make a reciprocating movement, and drive the inserts fixedly connected to the fixed rings to make a reciprocating movement; at the same time, drive the scissors to make a reciprocating movement, so that the inserts embed the coil wound around the wire-winding claws into the wire-inserting mold and cut it at the same time.

[0018] Preferably, it further includes a flipping mechanism for replacing the wire-inserting molds. The flipping mechanism includes a flipping roller and a driving motor. The flipping roller is rotatably connected to the frame, and the driving motor is fixedly connected to the frame. Several groups of the wire-inserting molds are respectively detachably connected to the flipping roller, and several groups of the wire-inserting molds are evenly distributed along the axial direction of the flipping roller. Each group of the wire-inserting molds includes several wire-inserting molds, and several of the wire-inserting molds are evenly distributed around the axial direction of the flipping roller. When the flipping roller rotates to make the wire-inserting molds face the rotating shaft, a plurality of the wire-winding claws rotate to abut against the wire-inserting molds.

[0019] By adopting the above technical solution, after a plurality of wire-winding claws on the rotating shaft are all wound, the driving motor drives the flipping roller to rotate so that several wire-inserting molds on the same plane respectively face the corresponding rotating shafts; enabling a plurality of wire-winding claws on the rotating shaft to rotate to abut against the wire-inserting molds; when the plurality of wire-winding claws rotate away from the wire-inserting molds, the driving motor drives the flipping roller to rotate so that the wire-inserting molds embedded with coils are out of the range of the wire-winding claws, facilitating the removal of the wire-inserting molds from the flipping roller.

[0020] Preferably, each of the several wire-inserting molds is provided with a fitting block, and the fitting block is provided with a slot. The flipping roller is provided with a fitting groove that can cooperate with the fitting block, and a plug block that can cooperate with the plug-in block is slidably connected in the fitting groove.

A hydraulic cylinder is provided on the flipping roller, and one end of the piston rod of the hydraulic cylinder is fixedly connected to the fixing plate.

[0021] By adopting the above technical solution, through the piston movement of the piston rod of the hydraulic cylinder, the fixing plate is driven to reciprocate. When the fitting block on the wire-inserting mold is placed in the fitting groove and the fitting block cooperates with the fitting groove, the fixing plate is moved so that the plug block cooperates with the clamping groove to lock the position of the fitting block in the fitting groove, thereby limiting the position of the wire-inserting mold on the flipping roller. When the fixing plate moves until the plug block disengages from the clamping groove, the fitting block can be taken out of the fitting groove, and thus the wire-inserting mold can be taken out from the flipping roller; facilitating the installation and disassembly of the wire-inserting molds.

[0022] The technical effects of the present invention are mainly reflected in the following aspects: 1. The present invention sets up winding claws and wire-inserting molds. First, the driving mechanism drives multiple winding claws to rotate simultaneously to a direction perpendicular to the axis of the rotating shaft, and then the winding mechanism winds copper wires around the winding claws respectively. After any one winding claw is wound, the driving mechanism drives the rotating shaft to rotate, turns different winding claws towards the winding mechanism for winding. After all the winding claws are wound, the driving mechanism drives the multiple winding claws to rotate to a direction parallel to the axis of the rotating shaft, and finally the wire-pushing and cutting mechanism pushes the coils wound on the winding claws into the corresponding wire-inserting molds and cuts the copper wires from the winding claws; it is convenient for mass production, facilitates batch processing of multiple stator windings with the same specifications, improves production efficiency, can keep the copper wire windings in a preset shape, improves the winding quality, ensures the integrity and insulation performance of the windings, and reduces the probability of failures occurring during the equipment operation to the motor; 2. The present invention sets up a first driving component. According to the principle of a four-bar hinge, when the sliding disk moves towards the side of the winding claw, the winding claw rotates towards the side of the wire-inserting mold to a direction parallel to the axis of the rotating shaft and abuts against the wire-inserting mold. When the sliding disk moves towards the side away from the winding claw, the winding claw rotates towards the side away from the wire-inserting mold to a direction perpendicular to the axis of the rotating shaft; by setting a clamping rod and making the clamping rod slide in the chute on the circumferential surface of the inner ring of the sliding disk, the movement and rotation of several sliding disks are not interfered; through the piston movement of the piston rod of the first cylinder, the push-pull plate drives multiple sliding disks to reciprocate along the axis of the rotating shaft, so that the winding claws on several rotating shafts move simultaneously, reducing the possibility of different wire groups wound on different rotating shafts having different shapes, and at the same time reducing the possibility of the wound copper wires being damaged by accidental extrusion, collision, etc., ensuring the integrity and insulation performance of the windings; 3. The present invention sets up a flipping mechanism. After all the winding claws on the rotating shaft are wound, the driving motor drives the flipping roller to rotate so that several wire-inserting molds on the same plane are respectively facing the corresponding rotating shafts; the multiple winding claws on the rotating shaft can be rotated to abut against the wire-inserting molds; when the multiple winding claws rotate away from the wire-inserting molds, the driving motor drives the flipping roller to rotate so that the wire-inserting molds with embedded coils are out of the range of the winding claws, facilitating the removal of the wire-inserting molds from the flipping roller.

[0031] The following will further describe the present application in detail Figure 1-7 to make the technical solution of the present application easier to understand and master.

[0032] The embodiment of the present application discloses a fully automatic wire winding machine for stator assembly.

[0033] Referring to Figure 1 and Figure 2 , a fully automatic wire winding machine for stator assembly includes a frame 1, a driving mechanism 2, a wire winding mechanism 3 and a wire pushing and cutting mechanism 4. Three rotating shafts 11 are rotatably connected to the frame 1, and a plurality of wire winding claws 12 are respectively rotatably connected to the three rotating shafts 11. The driving mechanism 2 is used to respectively drive the rotation of the three rotating shafts 11 and the plurality of wire winding claws 12. When the driving mechanism 2 drives the plurality of wire winding claws 12 to rotate perpendicular to the axis of the rotating shaft 11, the wire winding mechanism 3 is used to wind copper wires around the plurality of wire winding claws 12 respectively. Three groups of wire embedding dies 13 are detachably connected to the frame 1, and the three groups of wire embedding dies 13 respectively correspond to the three rotating shafts 11. When the driving mechanism 2 drives the plurality of wire winding claws 12 to rotate parallel to the axis of the rotating shaft 11, the wire pushing and cutting mechanism 4 is used to push the coil wound on the wire winding claw 12 into the corresponding wire embedding die 13 and cut the copper wire from the wire winding claw 12.

[0034] Referring to Figure 1 andFigure 2 , first, the driving mechanism 2 simultaneously drives a plurality of wire winding claws 12 to rotate to a direction perpendicular to the axis of the rotating shaft 11, and then the wire winding mechanism 3 winds the copper wires around the wire winding claws 12 respectively. After any one of the wire winding claws 12 is wound, the driving mechanism 2 drives the rotating shaft 11 to rotate, so that different wire winding claws 12 face the wire winding mechanism 3 for winding. After all the wire winding claws 12 are wound, the driving mechanism 2 drives the plurality of wire winding claws 12 to rotate to a direction parallel to the axis of the rotating shaft 11. Finally, the wire pushing and cutting mechanism 4 pushes the coils wound around the wire winding claws 12 into the corresponding wire embedding molds 13 and cuts the copper wires from the wire winding claws 12; it is convenient for mass production, facilitates batch processing of a plurality of stator windings with the same specifications, improves production efficiency, can keep the copper wire windings in a preset shape, improves the winding quality, ensures the integrity and insulation performance of the windings, and reduces the probability of failures occurring from equipment to motor operation.

[0035] Refer to Figure 4 and Figure 5 , the driving mechanism 2 includes a first driving component 21. The first driving component 21 is used to drive the simultaneous rotation of a plurality of wire winding claws 12. The first driving component 21 includes a first air cylinder 211, a push-pull plate 212 and three sliding disks 213. The push-pull plate 212 is slidably connected to the frame 1 along the axis direction of the rotating shaft 11. Three clamping rods 214 are fixedly connected to the push-pull plate 212. The three sliding disks 213 respectively correspond to the three rotating shafts 11. The three sliding disks 213 are respectively coaxially and slidably connected to the corresponding rotating shafts 11. Chutes 215 are respectively formed on the circumferential surfaces of the inner circles of the three sliding disks 213. The three clamping rods 214 are respectively slidably connected to the corresponding sliding disks 213 around the bottom surfaces of the corresponding sliding disks 213. A plurality of hinge rods 216 are respectively hingedly connected to the plurality of wire winding claws 12, and the ends of the plurality of hinge rods 216 far from the wire winding claws 12 are respectively hingedly connected to the corresponding sliding disks 213. The first air cylinder 211 is fixedly connected to the frame 1, and one end of the piston rod of the first air cylinder 211 is fixedly connected to the push-pull plate 212.

[0036] Refer to Figure 4 and Figure 5, based on the principle of the hinge four-bar mechanism, when the sliding plate 213 moves towards the side of the wire winding claw 12, the wire winding claw 12 rotates towards the side of the wire embedding die 13 to be parallel to the axis direction of the rotating shaft 11 and abuts against the wire embedding die 13. When the sliding plate 213 moves towards the side away from the wire winding claw 12, the wire winding claw 12 rotates towards the side away from the wire embedding die 13 to be perpendicular to the axis direction of the rotating shaft 11; by setting the clamping rod 214 and making the clamping rod 214 slide in the chute 215 on the circumferential surface of the inner circle of the sliding plate 213, the movement and rotation of the three sliding plates 213 are not interfered; through the piston movement of the piston rod of the first cylinder 211, the push-pull plate 212 drives multiple sliding plates 213 to reciprocate along the axis direction of the rotating shaft 11, so that the wire winding claws 12 on the three rotating shafts 11 move simultaneously, reducing the possibility that the wire groups wound on different rotating shafts 11 have different shapes, and at the same time reducing the possibility that the wound copper wires are damaged by accidental extrusion, collision, etc., ensuring the integrity and insulation performance of the winding.

[0037] Refer to Figure 4 and Figure 6 , the driving mechanism 2 further includes a second driving component 22, and the second driving component 22 is used to simultaneously drive the rotation of the three rotating shafts 11. The second driving component 22 includes three second synchronous pulleys 221, a second synchronous belt 222 and a second motor 223. The three second synchronous pulleys 221 respectively correspond to the three rotating shafts 11. The three second synchronous pulleys 221 are respectively coaxially and fixedly connected to the corresponding rotating shafts 11. The second synchronous belt 222 is simultaneously wound around and meshed with the three second synchronous pulleys 221. The second motor 223 is fixedly connected to the frame 1, and one end of the output shaft of the second motor 223 is coaxially and fixedly connected to any one of the second synchronous pulleys 221.

[0038] Refer to Figure 4 and Figure 6 , the second motor 223 drives any one of the second synchronous pulleys 221 to rotate. Through the second synchronous belt 222 being simultaneously wound around and meshed with the three second synchronous pulleys 221, the three second synchronous pulleys 221 rotate simultaneously, thereby driving the multiple rotating shafts 11 to rotate simultaneously, making the rotation of the three rotating shafts 11 consistent, facilitating mass production, reducing the possibility that the wire groups wound on different rotating shafts 11 have different shapes, and at the same time reducing the possibility that the wound copper wires are damaged by accidental extrusion, collision, etc., ensuring the integrity and insulation performance of the winding.

[0039] Refer to Figure 1 and Figure 2The winding mechanism 3 includes three winding rods 31, three groups of guide wheels 32 and a fourth driving assembly 33. Three bobbins 34 with copper wires are installed next to the frame 1. The three groups of guide wheels 32 are rotatably connected to the frame 1 respectively. One end of the three winding rods 31 in the length direction is respectively rotated along the rotation direction perpendicular to the rotation axis 11 and connected to the frame 1. The three winding rods 31 correspond to the three groups of guide wheels 32 and the three bobbins 34 respectively. The copper wires on the three bobbins 34 are respectively passed around the corresponding guide wheels 32 and passed through the corresponding winding rods 31. The fourth driving assembly 33 is used to simultaneously drive the rotation of the three winding rods 31. The three winding rods 31 are driven to rotate simultaneously by the fourth driving assembly 33, so that the guides passed through the three winding rods 31 are respectively wound on multiple winding claws 12, and the copper wire on the bobbin 34 is guided by setting three groups of guide wheels 32, so that the wire on the bobbin 34 moves from the bobbin 34 to the winding rod 31, so that the rotation of the plurality of winding rods 31 is kept consistent, which is convenient for mass production and reduces the possibility of different shapes of wire groups wound on different rotating shafts 11.

[0040] Reference Figure 1 and Figure 2 The fourth driving assembly 33 includes three fourth synchronous wheels, a fourth synchronous belt and a fourth motor. The three fourth synchronous wheels correspond to the three winding rods 31 respectively. The three fourth synchronous wheels are coaxial with the rotation axes of the corresponding winding rods 31 and fixedly connected to the corresponding winding rods 31. The fourth synchronous belt is simultaneously wound around the three fourth synchronous wheels and meshed with the three fourth synchronous wheels at the same time. The fourth motor is fixedly connected to the frame 1. One end of the output shaft of the fourth motor is coaxial and fixedly connected to any fourth synchronous wheel. The fourth motor drives any fourth synchronous wheel to rotate. The meshing connection of the fourth synchronous belt with the three fourth synchronous wheels makes the three fourth synchronous wheels rotate simultaneously and drives the corresponding winding rods 31 to rotate.

[0041] Reference Figure 3 , Figure 4 and Figure 5, the hair clipper line mechanism 4 includes three groups of inserts 41, three scissors 42 and a third driving component 43. The three groups of inserts 41 respectively correspond to the three rotating shafts 11. The three groups of inserts 41 are respectively slidably connected to the rotating shafts 11 along the axial directions of the corresponding rotating shafts 11. Each group of inserts 41 includes a plurality of inserts 41, and the plurality of inserts 41 are located between two adjacent wire winding claws 12. The three scissors 42 respectively correspond to the three rotating shafts 11. The three scissors 42 are respectively slidably connected to the frame 1 along the axial directions of the corresponding rotating shafts 11. Springs are fixedly connected to the two sides of the handles of the three scissors 42, and the two ends of the springs are respectively fixedly connected to the handles on both sides of the scissors 42. The springs always drive the handles on both sides to rotate towards the opposite sides. Three guide rails 44 are fixedly connected to the frame 1. The three guide rails 44 respectively correspond to the three scissors 42. The three guide rails 44 are respectively fixedly connected to the frame 1. One end of the three guide rails 44 close to the wire embedding die 13 to the end far from the wire embedding die 13 is arranged in a gradually expanding shape. The opposite sides of the two cutting heads of the three scissors 42 respectively abut against the two side surfaces of the guide rails 44. The third driving component 43 is used to drive the three groups of inserts 41 and the three scissors 42 to move simultaneously.

[0042] Refer to Figure 3 , Figure 4 and Figure 5 , when the third driving component 43 drives the scissors 42 and the inserts 41 to slide towards the wire embedding die 13, the inserts 41 push the coil wound around the wire winding claws 12 and embed it into the wire embedding die 13, which can keep the copper wire winding in a preset shape. The slide rail makes the cutting head part of the scissors 42 rotate towards the opposite side to cut the copper wire, so that the coil is cut while being embedded in the wire embedding die 13, reducing the possibility of the coil coming loose; when the scissors 42 slide towards the side far from the wire embedding die 13, the springs drive the handles on both sides to rotate towards the opposite sides, so that the two cutting head parts of the scissors 42 rotate towards the opposite sides, and the inserts 41 are reset at the same time.

[0043] Refer to Figure 3 , Figure 4 and Figure 5, the third driving component 43 includes a connecting plate 431, three limiting rods 432 and a third cylinder 434. The plate is slidably connected to the frame 1 along the axis direction of the rotating shaft 11. The three limiting rods 432 are respectively fixedly connected to the connecting plate 431. Fixed rings 433 are respectively rotatably connected to the three limiting rods 432. The three groups of inserts 41 are respectively fixedly connected to the corresponding fixed rings 433. And the rotating shafts 11 of the three scissors 42 are respectively fixedly connected to the connecting plate 431. The third cylinder 434 is fixedly connected to the frame 1. One end of the piston rod of the third cylinder 434 is fixedly connected to the connecting plate 431. Through the piston movement of the piston rod of the third cylinder 434, the connecting plate 431 makes a reciprocating movement on the frame 1, so that the limiting rods 432 and the fixed rings 433 rotatably connected to the limiting rods 432 make a reciprocating movement, and drive the inserts 41 fixedly connected to the fixed rings 433 to make a reciprocating movement; at the same time, drive the scissors 42 to make a reciprocating movement, so that the inserts 41 cut the coil wound around the winding claws 12 while embedding it into the wire embedding mold 13.

The flipping mechanism 5 includes a flipping roller 51 and a driving motor 52. The flipping roller 51 is rotatably connected to the frame 1. The driving motor 52 is fixedly connected to the frame 1. The three groups of wire embedding molds 13 are respectively detachably connected to the flipping roller 51. The three groups of wire embedding molds 13 are evenly distributed along the axis direction of the flipping roller 51. Each group of wire embedding molds 13 includes three wire embedding molds 13. The three wire embedding molds 13 are evenly distributed around the axis direction of the flipping roller 51. When the flipping roller 51 rotates to make the wire embedding mold 13 face the rotating shaft 11, the multiple winding claws 12 rotate to abut against the wire embedding mold 13. After the multiple winding claws 12 on the rotating shaft 11 are all wound, the driving motor 52 drives the flipping roller 51 to rotate so that the three wire embedding molds 13 on the same plane respectively face the corresponding rotating shafts 11; so that the multiple winding claws 12 on the rotating shaft 11 can rotate to abut against the wire embedding mold 13; when the multiple winding claws 12 rotate to leave the wire embedding mold 13, the driving motor 52 drives the flipping roller 51 to rotate so that the wire embedding mold 13 embedded with the coil is out of the range of the winding claws 12, which is convenient for removing the wire embedding mold 13 from the flipping roller 51.

[0045] Refer to Figure 1 and Figure 7, mating blocks 53 are fixedly connected to the three wire embedding molds 13 respectively, and slots 54 are formed in the mating blocks 53. Matching grooves 55 that can cooperate with the mating blocks 53 are formed in the turning roller 51, and plugging blocks 56 that can cooperate with the plugging blocks 56 are slidably connected in the matching grooves 55. A fixing plate 57 is slidably connected to the turning roller 51. The plugging blocks 56 in the three matching grooves 55 are fixedly connected to the fixing plate 57 respectively. A hydraulic cylinder 58 is fixedly connected to the turning roller 51, and one end of the piston rod of the hydraulic cylinder 58 is fixedly connected to the fixing plate 57. Through the piston movement of the piston rod of the hydraulic cylinder 58, the fixing plate 57 is driven to move reciprocally. When the mating block 53 on the wire embedding mold 13 is placed in the mating groove 55 and the mating block 53 cooperates with the mating groove 55, the fixing plate 57 is moved to make the plugging block 56 cooperate with the clamping groove, so as to lock the position of the mating block 53 in the mating groove 55, thereby limiting the position of the wire embedding mold 13 on the turning roller 51. When the fixing plate 57 moves until the plugging block 56 disengages from the clamping groove, the mating block 53 can be taken out of the mating groove 55, thereby taking out the wire embedding mold 13 from the turning roller 51; it is convenient for the installation and disassembly of the wire embedding mold 13.

[0046] Certainly, the above are only typical examples of this application. In addition, this application can also have many other specific implementation manners. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by this application.
