[0041] Please refer to Figures 1 to 9 As shown, the present invention provides a rotary multi-station foot-wrapping machine 100 for manufacturing inductors. The inductor includes a base and a coil. The rotary multi-station foot-wrapping machine 100 includes a frame 1, an indexing plate 2, a feeding mechanism 3, a first transfer mechanism 4, and a foot-wrapping mechanism 5. The frame 1 is provided with a feeding position 11, an assembly position 12, and a foot-wrapping position 13. The indexing plate 2 is arranged on the frame 1. The feeding position 11, the assembly position 12, and the foot-wrapping position 13 are arranged at intervals along the circumferential direction of the indexing plate 2. The indexing plate 2 is provided with a clamping mechanism 21 for clamping the base and the coil. The feeding mechanism 3 is arranged on the frame 1 and corresponds to the feeding position 11 for feeding the base to the clamping mechanism 21. The first transfer mechanism 4 is arranged on the frame 1 and corresponds to the assembly position 12 for transferring the coil to the clamping mechanism 21 so that the coil and the base are combined. The foot-wrapping mechanism 5 corresponds to the foot-wrapping position 13 for winding the leads of the coil around the pins of the base. Among them, the indexing plate 2 rotates relative to the frame 1 so that the clamping mechanism 21 sequentially passes through the feeding position 11, the assembly position 12, and the foot-wrapping position 13 to complete the foot-wrapping process.

[0042] In this embodiment, the indexing plate 2 is arranged at the middle position of the frame 1, the loading position 11, the assembly position 12 and the foot-binding position 13 are arranged along the peripheral position of the indexing plate 2, and the loading mechanism 3, the first transfer mechanism 4 and the foot-binding mechanism 5 are arranged corresponding to the loading position 11, the assembly position 12 and the foot-binding position 13 respectively. When the turntable multi-station foot-binding machine 100 is running, the indexing plate 2 rotates and drives the clamping mechanism 21 to pass through the loading position 11, the assembly position 12 and the foot-binding position 13 in sequence. When the clamping mechanism 21 is at the loading position 11, the loading mechanism 3 loads the base to the clamping mechanism 21, and then the indexing plate 2 moves the clamping mechanism 21 to the assembly position 12, the first transfer mechanism 4 transfers the coil to the clamping mechanism 21, and pre-installs the coil to the clamping mechanism, and then the indexing plate 2 moves the clamping mechanism 21 to the foot-binding position 13, and the foot-binding mechanism 5 winds the wire feet of the coil on the pins of the base to complete the foot-binding process of inductor production. In this way, the turntable-type multi-station foot-binding machine 100 realizes the automation of coil and base foot binding, and also makes the layout of the feeding mechanism 3, the first transfer mechanism 4 and the foot-binding mechanism 5 on the frame 1 more regular and compact, which is conducive to the production and assembly of the turntable-type multi-station foot-binding machine 100.

[0043] In actual implementation, the dividing plate 2 includes a rotating drive member and a frame. The frame can be disc-shaped or forked. The rotating drive member is connected to the frame 1, and the frame is connected to the output end of the rotating drive member. The clamping mechanism 21 is arranged at a position close to the edge of the frame. The rotating drive member drives the frame to rotate to drive the clamping mechanism 21 to pass through the loading position 11, the assembly position 12 and the foot binding position 13 in sequence.

[0044] In one embodiment of the present invention, Figure 1 , Figure 2 and Figure 7 As shown, the frame 1 is also provided with a material unloading position 14, and the turntable multi-station further includes a second transfer mechanism 6. The second transfer mechanism 6 is provided on the frame 1 corresponding to the material unloading position 14, and the second transfer mechanism 6 is used to transfer the inductor after foot binding.

[0045] In this embodiment, the frame 1 is also provided with a material unloading position 14, and the indexing plate 2 drives the clamping mechanism 21 to sequentially pass through the material loading position 11, the assembly position 12, the foot binding position 13 and the material unloading position 14. When the indexing plate 2 drives the clamping mechanism 21 to reach the material unloading position 14, the second transfer mechanism 6 transfers the inductor that has completed the foot binding in the clamping mechanism 21 to transfer the inductor to the next process or unloading. When the inductor is transferred, the indexing plate 2 transfers the empty clamping mechanism 21 to the material loading position 11 for loading, so as to repeat the process. The turntable-type multi-station foot binding machine 100 can continuously perform the processing process, effectively improving the efficiency of batch foot binding.

[0046] In one embodiment of the present invention, Figure 1 and Figure 2As shown in the figure, the wire winding mechanism 5 includes a first wire winding device 51 and a second wire winding device 52. The first wire winding device 51 is arranged on the frame 1 corresponding to the wire winding position 13. The first wire winding device 51 is used to wind part of the wire leads of the coil around the pins of the base. The second wire winding device 52 is arranged on the frame 1 corresponding to the blanking position 14. The second wire winding device 52 is used to wind the remaining wire leads of the coil around the pins of the base.

[0047] In this embodiment, the first wire winding device 51 is arranged on the frame 1 corresponding to the wire winding position 13, and the second wire winding device 52 is arranged on the frame 1 corresponding to the blanking position 14. Thus, when the indexing plate 2 drives the clamping mechanism 21 carrying the coil and the base to move to the wire winding position 13, the first wire winding device 51 can wind part of the wire leads of the coil. Then, when it reaches the blanking position 14, the second wire winding device 52 winds the remaining wire leads of the coil. After the second wire winding device 52 completes the wire winding of the inductor, the second transfer mechanism 6 transfers the inductor. In this way, the wire winding is carried out step by step. The wire winding position 13 is the first processing position, and the blanking position 14 is the second processing position. When there are multiple clamping mechanisms 21 on the indexing plate 2, the first wire winding device 51 and the second wire winding device 52 can carry out wire winding simultaneously to achieve multi-station wire winding, so as to improve the overall production efficiency.

[0048] Optionally, the number of clamping mechanisms 21 on the indexing plate 2 can be set to two, three, four, etc., which is not specifically limited here. In actual implementation, the wire leads of the coil are generally four, and the pins of the base correspond to the wire leads one by one. The first wire winding device 51 can wind two wire leads on the same side, and the second wire winding device 52 can wind the remaining two wire leads.

[0049] In an embodiment of the present utility model, as Figure 1 、 Figure 2 and Figure 8 shown, both the first wire winding device 51 and the second wire winding device 52 include a wire winding driving part 53 and a wire winding part 54 arranged on the frame 1. The wire winding driving part 53 is connected to the frame 1, and the wire winding part 54 is connected to the output end of the wire winding driving part 53. The wire winding part 54 is provided with a wire winding hole 541 for the wire lead to pass through.

[0050] In this embodiment, both the first wire winding device 51 and the wire winding device include a wire winding driving part 53 and a wire winding part 54. The wire winding part 54 is provided with a wire winding hole 541. When carrying out wire winding, the wire winding driving part 53 drives the wire winding part 54 to approach the wire lead of the coil and makes the wire lead of the coil pass through the wire winding hole 541 of the wire winding part 54. Then, the wire winding driving part 53 drives the wire winding part 54 to drive the wire lead to move around the pin of the base so that the wire lead is wound around the pin of the base. Finally, the wire winding driving part 53 drives the wire winding part 54 to move away from the wire lead to draw the wire lead out of the wire winding hole 541, thus completing the wire winding.

[0051] In actual implementation, the wire-wrapping driving member 53 includes three driving members in different directions, such as the X-axis driving member 531, the Y-axis driving member 532, and the Z-axis driving member 533. The X-axis driving member 531 is connected to the frame 1, the Y-axis driving member 532 is connected to the output end of the X-axis driving member 531, and the Z-axis driving member 533 is connected to the output end of the Y-axis driving member 532. In this way, the wire-wrapping driving member 53 can drive the wire-wrapping member 54 to approach or move away from the lead of the coil, and drive the wire-wrapping member 54 to drive the lead to move around the pin of the base along a rectangular or square trajectory. The wire-wrapping member 54 may include a driving member and two wire-wrapping rods connected to the output end of the driving member. The ends of the two wire-wrapping rods can enclose to form a wire-wrapping hole 541. The driving member can drive the two wire-wrapping rods to approach or move away from each other, so that the lead of the coil can more easily enter or be drawn out from the wire-wrapping hole 541. The installation method of the driving member and the wire-wrapping rods is similar to that of a pneumatic gripper.

[0052] It can be understood that when the first wire-wrapping device 51 and the second wire-wrapping device 52 are arranged in different directions, the driving directions of the X-axis driving members 531 in them are different, and the driving directions of the Y-axis driving members 532 are also different.

[0053] In an embodiment of the present invention, as Figure 1 , Figure 2 and Figure 7 shown, the indexing plate 2 is provided with four clamping mechanisms 21, and the four clamping mechanisms 21 are respectively arranged corresponding to the loading position 11, the assembling position 12, the wire-wrapping position 13, and the unloading position 14. The clamping mechanism 21 is provided with a fixing cavity.

[0054] In this embodiment, the indexing plate 2 is provided with four clamping mechanisms 21. The clamping mechanism 21 fixes the base and / or the coil through the fixing cavity. The four clamping mechanisms 21 are respectively arranged corresponding to the loading position 11, the assembling position 12, the wire-wrapping position 13, and the unloading position 14. The indexing plate 2 drives the four clamping mechanisms 21 to sequentially pass through the loading position 11, the assembling position 12, the wire-wrapping position 13, and the unloading position 14 and cycle. In this way, the loading mechanism 3, the first transfer mechanism 4, the wire-wrapping mechanism 5, and the second transfer mechanism 6 can operate simultaneously, respectively performing base loading, coil loading, wire-wrapping of the coil and the base, and transfer of the inductor on different clamping mechanisms 21, realizing flow processing and greatly improving the processing efficiency of the rotary multi-station wire-wrapping machine 100.

[0055] In actual implementation, the wire-wrapping position 13 is provided with a first wire-wrapping device 51, and the unloading position 14 is provided with a second wire-wrapping device 52 to perform wire-wrapping step by step, thereby reducing the processing beat of wire-wrapping and improving the production efficiency of the rotary multi-station wire-wrapping machine 100. The indexing plate 2 can be arranged in a cross shape, and the four clamping mechanisms 21 are respectively arranged at the ends of each protruding section, which is not specifically limited here.

[0056] In an embodiment of the present invention, as Figure 1 andFigure 4 As shown, the first transfer mechanism 4 includes a first horizontal drive member 41, a first lifting drive member 42, a first clamping member 43, and a wire protection device 44. The first horizontal drive member 41 is disposed on the frame 1. The first lifting drive member 42 and the wire protection device 44 are connected to the output end of the first horizontal drive member 41. The first clamping member 43 is connected to the output end of the first lifting drive member 42. The first clamping member 43 is provided with a clamping cavity 431 for clamping the coil. The wire protection device 44 is provided with a wire protection cavity 441 communicating with the clamping cavity 431 for protecting the leads of the coil.

[0057] In this embodiment, the driving direction of the first horizontal drive member 41 and the driving direction of the first lifting drive member 42 are perpendicularly arranged. When the first transfer mechanism 4 picks up the coil, the first horizontal drive member 41 drives the first lifting drive member 42 to drive the first clamping member 43 and the coil to reach the combination position. Then, the first lifting drive member 42 drives the first clamping member 43 to approach the clamping mechanism 21 located at the combination position so that the coil is combined with the base. The clamping mechanism 21 fixes the coil. Then, the first clamping member 43 releases the coil, and the first lifting drive member 42 drives the first clamping member 43 to leave the clamping mechanism 21 to avoid interfering with the rotation of the indexing plate 2. It can be understood that the process of the first transfer mechanism 4 picking up the coil is similar to the above process and will not be elaborated here. During the process of the first clamping member 43 clamping the coil, the leads of the coil extend into the wire protection cavity 441 of the wire protection device 44 to protect the leads of the coil and prevent the leads of the coil from being bent or wound during the transfer process, which is not conducive to the combination of the coil and the base.

[0058] In actual implementation, the wire protection device 44 includes a first wire protection drive member 442, a second wire protection drive member 443, and a wire protection member 444. The wire protection member 444 is provided with a wire protection cavity 441. The first wire protection drive member 442 is connected to the output end of the first horizontal drive member 41. The second wire protection drive member 443 is connected to the output end of the first wire protection drive member 442. The wire protection member 444 is connected to the output end of the second wire protection drive member 443. The first wire protection drive member 442 and the second wire protection drive member 443 can drive the wire protection member 444 to approach or move away from the clamping cavity 431 in two directions to accurately extend the leads of the coil into the wire protection cavity 441. The wire protection member 444 can be arranged in the shape of a pneumatic gripper.

[0059] In an embodiment of the present utility model, as Figure 1 and Figure 4 shown, the second transfer mechanism 6 includes a second horizontal drive member 61, a second lifting drive member 62, and a second clamping member 63. The second horizontal drive member 61 is disposed on the frame 1. The second lifting drive member 62 is connected to the output end of the second horizontal drive member 61. The second clamping member 63 is connected to the output end of the second lifting drive member 62. The second clamping member 63 is used for clamping the inductor.

[0060] In this embodiment, the driving direction of the second translation driving member 61 and the driving direction of the second lifting driving member 62 are perpendicular to each other. The second translation driving member 61 drives the second lifting driving member 62 to drive the second clamping member 63 to reach the blanking position 14. The second lifting driving member 62 drives the second clamping member 63 to approach the clamping mechanism 21 located at the blanking position 14. The second clamping member 63 clamps the inductor to be transferred, and the clamping mechanism 21 releases the inductor. The second lifting driving member 62 drives the second clamping member 63 to move away from the clamping mechanism 21 to avoid interfering with the rotation of the indexing plate 2. Then, the second translation driving member 61 drives the second lifting driving member 62 and the second clamping member 63 to transfer the inductor to the next process or perform blanking, thus completing the transfer of the inductor.

[0061] In an embodiment of the present utility model, as Figures 2 to 5 shown, the fixed cavity includes a first fixed cavity 214 and a second fixed cavity 215 that are connected and communicate with each other, and are respectively used for limiting the coil and the base; the clamping mechanism 21 includes a mounting seat 211, two pairs of clamping arms 212 and two transmission members 213. The mounting seat 211 is connected to the indexing plate 2. The mounting seat 211 is provided with a chute 2111 corresponding to each pair of clamping arms 212 and a through cavity 2112 communicating with the chute 2111. Each pair of clamping arms 212 is slidably disposed in a chute 2111. The two pairs of clamping arms 212 respectively enclose to form a first fixed cavity 214 and a second fixed cavity 215. One end of each transmission member 213 is in transmission connection with a pair of clamping arms 212 through the through cavity 2112, and the other end of each transmission member 213 is elastically connected to the mounting seat 211. The rotary multi-station wire winding machine 100 further includes a plurality of clamping driving members 22 respectively corresponding to the feeding position 11, the assembling position 12 and the blanking position 14. The output end of the clamping driving member 22 is correspondingly arranged with the transmission member 213.

[0062] In this embodiment, the fixing cavity includes a first fixing cavity 214 and a second fixing cavity 215 to fix the coil and the base respectively. The mounting seat 211 is connected to the indexing plate 2 and is provided with two sliding grooves 2111. The clamping arms 212 are limited in the sliding grooves 2111 through a clamping structure and can move along the sliding grooves 2111. In this way, the clamping arms 212 of the same pair can approach or move away from each other to clamp the base or the coil. One end of the transmission member 213 passes through the through cavity 2112 and is limitedly connected to the inclined protrusion 2131 on the clamping arm 212 through an inclined groove 2121. The other end of the transmission member 213 extends out of the through cavity 2112 and is elastically connected to the mounting seat 211 through an elastic member 216. It can be understood that the setting direction of the sliding groove 2111 is perpendicular to the extending direction of the through cavity 2112. The transmission member 213 is elastically connected to the mounting seat 211 by sleeving the elastic member 216, and the elastic member 216 is limited between the outer wall of the mounting seat 211 and the end of the transmission member 213. When the transmission member 213 moves along the through cavity 2112 towards the sliding groove 2111 under the action of an external force, the elastic member 216 is compressed, and the clamping arms 212 of the same pair move away from each other along the sliding groove 2111 through the cooperation of the inclined groove 2121 and the inclined protrusion 2131 to open the first fixing cavity 214 or the second fixing cavity 215, so as to facilitate the coil or the base to be placed into the corresponding fixing cavity; then the external force on the transmission member 213 is removed, the elastic member 216 rebounds, and the transmission member 213 moves along the through cavity 2112 in a direction away from the sliding groove 2111 to drive the clamping arms 212 of the same pair to approach relatively to clamp and fix the coil or the base. In this way, the clamping mechanism 21 and the clamping driving member 22 can be separately arranged. Only the clamping mechanism 21 needs to be arranged on the indexing plate 2, thereby reducing the load on the indexing plate 2 and improving the use accuracy and service life of the indexing plate 2.

[0063] In actual implementation, the first fixing cavity 214 is disposed above the second fixing cavity 215. When the indexing plate 2 rotates to drive the clamping mechanism 21 to reach the loading position 11, the output ends of the clamping driving members 22 disposed at the loading position 11 simultaneously push two transmission members 213, so that the two pairs of clamping arms 212 are separated from each other, opening the first fixing cavity 214 and the second fixing cavity 215. Then, the loading mechanism 3 moves the base to the second fixing cavity 215. Then, the output ends of the clamping driving members 22 located at the loading position 11 retract, and the elastic members 216 on the two transmission members 213 rebound, driving the transmission members 213 away from the sliding grooves 2111, thereby making the two pairs of clamping arms 212 approach each other, and the base is clamped and fixed. When the indexing plate 2 rotates to drive the clamping mechanism 21 to reach the assembling position 12, the output end of the clamping driving member 22 disposed at the assembling position 12 pushes the transmission member 213 corresponding to the first fixing cavity 214 to open the first fixing cavity 214. The first transfer mechanism 4 transfers the coil to the first fixing cavity 214 and makes the leads of the coil extend below the base. Then, the output end of the clamping driving member 22 retracts, so that the coil is clamped and fixed. When the indexing plate 2 rotates to drive the clamping mechanism 21 to reach the unloading position 14, the output ends of the clamping driving members 22 disposed at the unloading position 14 simultaneously push two transmission members 213 to open the first fixing cavity 214 and the second fixing cavity 215, so as to facilitate the second transfer mechanism 6 to transfer the inductor with the leg winding completed.

[0064] It can be understood that the widths of the output ends of the clamping driving members 22 provided at the loading position 11 and the unloading position 14 and the assembling position 12 are different to achieve simultaneously pushing two transmission members 213 or only pushing one transmission member 213.

[0065] In an embodiment of the present invention, as Figure 1 and Figure 6 shown, the loading mechanism 3 includes a vibrating disk 31 and a loading assembly 32. The vibrating disk 31 is connected to the frame 1 and is provided with a transmission channel 311 and an opening 312 communicating with the transmission channel 311. The loading assembly 32 includes a first driving member 321, a second driving member 322, and a loading clamping member 323. The first driving member 321 is connected to the frame 1, the second driving member 322 is connected to the output end of the first driving member 321, and the loading clamping member 323 is connected to the output end of the second driving member 322. The loading clamping member 323 is used for clamping the base.

[0066] In this embodiment, the vibrating bowl 31 transfers the base to the opening 312 of the transfer channel 311 in sequence through vibration. The first driving member 321 drives the second driving member 322 to drive the feeding clamping member 323 to move to the opening 312. The second driving member 322 drives the feeding clamping member 323 to approach the opening 312. The feeding clamping member 323 clamps the base located at the opening 312. The second driving member 322 drives the feeding clamping member 323 to move away from the opening 312. Then, the first driving member 321 drives the second driving member 322 to drive the feeding clamping member 323 and the base to move to the feeding position 11. The second driving member 322 drives the feeding clamping member 323 to approach the clamping mechanism 21 located at the feeding position 11. The clamping mechanism 21 fixes the base, and the feeding clamping member 323 releases the base. In this way, the transfer and feeding of the base are completed, realizing the automation of the base feeding.

[0067] During actual implementation, the driving direction of the first driving member 321 and the driving direction of the second driving member 322 are perpendicularly arranged.

[0068] In an embodiment of the present utility model, as Figure 1 and Figure 9 shown, the rotary multi-station foot-wrapping machine 100 further includes a wire pulling mechanism 7. The wire pulling mechanism 7 includes a wire pulling driving member 71, a wire pulling clamping member 72, and a wire pulling frame 73. The wire pulling frame 73 is provided with a placement surface 731. The wire pulling driving member 71 is connected to the frame 1. The wire pulling clamping member 72 is connected to the output end of the wire pulling driving member 71. The wire pulling clamping member 72 is provided with a wire pulling cavity 721 for clamping the wire foot. Among them, the wire pulling driving member 71 drives the wire pulling clamping member 72 to approach or move away from the wire pulling frame 73 to realize wire pulling.

[0069] In this embodiment, when the second transfer mechanism 6 can move the inductor to the wire pulling mechanism 7, the second transfer device moves the inductor to the placement surface 731 of the wire pulling frame 73. The excess wire feet of the protruding pins of the inductor protrude from the wire pulling frame 73. The wire pulling driving member 71 and the wire pulling clamping member 72 are respectively arranged on one side of the wire pulling frame 73. The wire pulling driving member 71 drives the wire pulling clamping member 72 to approach the wire pulling frame 73 until the wire foot extends into the wire pulling cavity 721. The wire pulling clamping member 72 reduces the wire pulling cavity 721 to clamp the wire foot in the wire pulling cavity 721. Then, the wire pulling driving member 71 drives the wire pulling clamping member 72 to drive the wire foot away from the wire pulling frame 73 to pull the excess wire foot off the pin.

[0070] During actual implementation, the wire pulling driving member 71 and the wire pulling clamping member 72 can include two groups. The two groups of wire pulling driving members 71 and wire pulling clamping members 72 are arranged on both sides of the wire pulling frame 73 to respectively correspond to the excess wire feet on both sides of the inductor. During wire pulling, the second transfer device can fix the inductor.

[0071] The above are only exemplary embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
