Description

Technical Field

[0001] This invention relates to the field of coil winding equipment technology, and in particular to a multi-axis synchronous winding device and a multi-axis synchronous winding machine. Background Technology

[0002] In the production of electronic components such as inductors, transformers, and miniature coils, the winding process directly affects the performance and consistency of the products. To improve production efficiency, multi-axis winding equipment is increasingly being used in existing technologies to achieve simultaneous processing of multiple coils.

[0003] Existing multi-axis winding equipment typically uses multiple motors to drive each winding shaft separately, or multiple transmission mechanisms to transmit power to each winding shaft separately. Due to differences in speed, response delay, and transmission errors among the various drive sources, synchronization deviations can easily occur between the winding shafts during high-speed operation of the equipment. This makes it difficult to maintain consistent speed and angle between different winding shafts, affecting the coil winding quality and product consistency.

[0004] Furthermore, in existing multi-axis winding equipment, the winding shafts are usually installed separately, lacking a unified installation reference. After long-term operation, the installation position is prone to shift due to vibration, wear, or structural deformation, causing a decrease in the coaxiality and positional accuracy between the winding shafts, affecting winding accuracy and equipment operational stability.

[0005] Therefore, a multi-axis synchronous winding device and a multi-axis synchronous winding machine that can improve the synchronicity and consistency of operation of each winding shaft and have high operational stability need to be designed. Summary of the Invention

[0017] Compared with the prior art, the advantages of this application are: This multi-axis synchronous winding device sets up an upper winding mechanism and a lower winding mechanism. In the upper winding mechanism, a first motor drives multiple sets of upper winding shafts synchronously via an upper synchronous transmission component. In the lower winding mechanism, a second motor drives multiple sets of lower winding shafts synchronously via a lower synchronous transmission component. This allows multiple sets of winding shafts in the same winding mechanism to be driven by the same power source, which can reduce the speed differences and response delays caused by independent driving of multiple motors, thereby improving the synchronicity and consistency of operation of each winding shaft.

[0018] Meanwhile, multiple upper winding shaft arrays are installed on the same upper reference frame, and multiple lower winding shaft arrays are installed on the same lower reference frame, so that each winding shaft has a unified installation reference. This helps to ensure the positional accuracy and coaxiality between each winding shaft, reduce installation offset caused by vibration, wear or structural deformation, and thus improve the operational stability and winding accuracy of the device.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please refer to Figures 1 to 17 One embodiment of the present invention provides a multi-axis synchronous winding device 100 for winding products such as inductors, transformers and miniature coils.

[0023] The multi-axis synchronous winding device 100 includes a frame 1, an upper winding mechanism 2, a lower winding mechanism 3 and a clamping and cutting mechanism 4 mounted on the frame 1, with the upper winding mechanism 2 and the lower winding mechanism 3 arranged vertically opposite each other.

[0024] The upper winding mechanism 2 includes: a first linear module 21, an upper reference frame 22, a first motor 23, multiple sets of upper winding shafts 24, and an upper synchronous transmission assembly.

[0025] The first linear module 21 is fixedly mounted on the frame 1 and extends vertically. The upper reference frame 22 is mounted on the output end of the first linear module 21. Understandably, the first linear module 21 can be an existing electric linear module, with its output end being a movable base. The upper reference frame 22 is mounted on the movable base via an upper mounting plate 26, thereby enabling it to move vertically under the drive of the first linear module 21.

[0026] The first motor 23 is mounted on the upper reference frame 22. Multiple sets of upper winding shafts 24 are arrayed and spaced apart on the upper reference frame 22. Optionally, the multiple sets of upper winding shafts 24 are rotatably mounted on the upper reference frame 22 via a first bearing (not shown in the figure). The upper synchronous transmission assembly is connected to the first motor 23 and the multiple sets of upper winding shafts 24 respectively, so as to synchronously transmit the power output by the first motor 23 to each upper winding shaft 24, causing each upper winding shaft 24 to rotate synchronously.

[0027] The lower winding mechanism 3 includes: a second linear module 31, a lower reference frame 32, a second motor 33, multiple sets of lower winding shafts 34, a lower synchronous transmission assembly 35, and a wire clamping mechanism.

[0028] The second linear module 31 is fixed to the frame 1 and extends vertically. The lower reference frame 32 is mounted on the output end of the second linear module 31. Understandably, the second linear module 31 can also be an existing electric linear module, and the lower reference frame 32 is fixed to the movable seat of the second linear module 31 by a lower mounting plate 37, so that it can move vertically under the drive of the second linear module 31.

[0029] The second motor 33 is mounted on the lower reference frame 32. Multiple sets of lower winding shafts 34 are arranged in a one-to-one correspondence with multiple sets of upper winding shafts 24, and are arrayed at intervals on the lower reference frame 32. Optionally, the multiple sets of lower winding shafts 34 are rotatably mounted on the lower reference frame 32 via second bearings (not shown in the figure). The lower synchronous transmission assembly 35 is connected to the second motor 33 and the multiple sets of lower winding shafts 34 respectively, so as to synchronously transmit the power output by the second motor 33 to each lower winding shaft 34, causing each lower winding shaft 34 to rotate synchronously.

[0030] The wire clamping mechanism is fixed on each set of lower winding shafts 34 and rotates with the lower winding shafts 34. During operation, the wire clamping mechanism holds the wire 710 to be wound near its free end. The upper end of the lower winding shaft 34 is provided with a insertion slot (not shown in the figure) for the corresponding upper winding shaft 24 to be inserted into, so as to complete the winding operation.

[0031] The clamping and cutting mechanism 4 is disposed on the wire 710 conveying path and is used to clamp the wire 710 during winding and to cut the wire 710 after winding is completed.

[0032] Preferably, both the first motor 23 and the second motor 33 are servo motors.

[0033] The working process of this embodiment is as follows: Before winding begins, the wire 710 is fed to a predetermined position and held near its free end by a wire clamping mechanism. Subsequently, the first motor 23 synchronously drives multiple sets of upper winding shafts 24 to rotate via an upper synchronous transmission assembly, while the second motor 33 synchronously drives multiple sets of lower winding shafts 34 to rotate synchronously in the opposite direction to the upper winding shafts 24 via a lower synchronous transmission assembly 35. Simultaneously, the first linear module 21 drives the upper reference frame 22 downwards, and the second linear module 31 drives the lower reference frame 32 upwards, causing the upper winding shafts 24 and their corresponding lower winding shafts 34 to move closer to each other. As the winding operation progresses, the ends of the upper winding shafts 24 gradually insert into the corresponding insertion slots of the lower winding shafts 34, and the wire 710 continuously winds around the ends of the upper winding shafts 24 to form coils 720.

[0034] Once the preset number of winding turns is reached, the first motor 23 and the second motor 33 stop driving, the upper winding shaft 24 and the lower winding shaft 34 stop rotating, and the first linear module 21 and the second linear module 31 stop moving. Subsequently, the clamping and cutting mechanism 4 operates to cut the wire 710, thereby completing the winding operation of the coil 720.

[0035] The multi-axis synchronous winding device 100 is configured with an upper winding mechanism 2 and a lower winding mechanism 3. In the upper winding mechanism 2, a first motor 23 drives multiple sets of upper winding shafts 24 synchronously via an upper synchronous transmission component. In the lower winding mechanism 3, a second motor 33 drives multiple sets of lower winding shafts 34 synchronously via a lower synchronous transmission component 35. This allows multiple sets of winding shafts in the same winding mechanism to be driven by the same power source, which can reduce the speed differences and response delays caused by independent driving of multiple motors, thereby improving the synchronicity and consistency of operation of each winding shaft.

[0036] Meanwhile, multiple sets of upper winding shafts 24 are arrayed on the same upper reference frame 22, and multiple sets of lower winding shafts 34 are arrayed on the same lower reference frame 32, so that each winding shaft has a unified installation reference. This helps to ensure the positional accuracy and coaxiality between each winding shaft, reduce installation offset caused by vibration, wear or structural deformation, and thus improve the operational stability and winding accuracy of the device.

[0037] Understandably, in this embodiment, the structure of the lower winding mechanism 3 is basically the same as that of the upper winding mechanism 2, except that a clamping mechanism is provided on each set of lower winding shafts 34. The following only provides a more detailed description of the specific structure of the upper winding mechanism 2; the lower winding mechanism 3 can be referred to the upper winding mechanism 2.

[0038] Alternatively, please refer to Figures 2 to 6 In this embodiment, the upper synchronous transmission assembly includes: a driving pulley 251, a driven pulley 252, and a synchronous belt (not shown in the figure).

[0039] The driving pulley 251 is rotatably mounted on the upper reference frame 22 and is connected to the output end of the first motor 23. Each driven pulley 252 is fixedly sleeved on the outer circumference of the corresponding upper winding shaft 24, so that the upper winding shaft 24 and the driven pulley 252 rotate synchronously. A synchronous belt is wound around the outer circumference of the driving pulley 251 and each driven pulley 252, so that under the drive of the first motor 23, the synchronous rotation of multiple sets of upper winding shafts 24 is realized through the synchronous belt.

[0040] Alternatively, please refer to Figures 4 to 6 In this embodiment, the upper reference frame 22 includes a bottom reference plate 221 and an upper reference plate 223 disposed opposite to each other, and a plurality of connecting columns 222 connecting the bottom reference plate 221 and the upper reference plate 223. Optionally, the bottom reference plate 221 and the upper reference plate 223 are integrally machined to form a reference structure, thereby having high structural rigidity and installation accuracy.

[0041] Multiple sets of upper winding shafts 24 are rotatably connected to the bottom reference plate 221 and the upper reference plate 223 respectively, and are inserted through the bottom reference plate 221; in this way, the installation rigidity and rotational stability of the upper winding shafts 24 can be effectively improved.

[0042] The synchronous transmission assembly also includes a synchronous belt tensioning plate 253 and several tension idler pulleys 254.

[0043] The timing belt tensioning plate 253 is movably mounted on the base plate 221, and several tension idler pulleys 254 are rotatably mounted on the timing belt tensioning plate 253. The timing belt tensioning plate 253 is provided with clearance holes o to avoid interference with the upper winding shaft 24 when the tensioning plate moves. Specifically, the clearance holes o are U-shaped holes.

[0044] The tension idler pulley 254 abuts against the synchronous belt and is located between two adjacent driven pulleys 252; it is used to adjust the tension of the synchronous belt to ensure that the synchronous belt maintains a stable tension during long-term operation. Specifically, multiple tension idler pulleys 254 are also arranged in a linear array on the synchronous belt tensioning plate 253.

[0045] Alternatively, please refer to Figures 4 to 6 In this embodiment, the synchronous transmission assembly further includes guide wheels 255 rotatably mounted on the bottom reference plate 221 and the upper reference plate 223. Driven by the driving pulley 251, the synchronous belt sequentially passes through the guide wheels 255, multiple driven pulleys 252, and tension idler pulleys 254 located between adjacent driven pulleys 252, finally returning to the driving pulley 251. Preferably, the synchronous belt is arranged in a serpentine pattern between the driven pulleys 252 and the tension idler pulleys 254, which allows the synchronous belt to maintain a large wrap angle and stable tension at each transmission point, thereby ensuring the synchronous transmission accuracy between the multiple upper winding shafts 24.

[0046] Optionally, the timing belt tensioner 253 can move relative to the bottom reference plate 221 in a direction perpendicular to the arrangement of the plurality of upper winding shafts 24. When the timing belt tensioner 253 moves, the plurality of tension idlers 254 mounted thereon move closer to or further away from the timing belt simultaneously, thereby achieving overall adjustment of the timing belt tension. Specifically, the timing belt tensioner 253 can be driven to move by the adjusting screw 27. After the operator rotates the adjusting screw 27, the timing belt tensioner 253 can be pushed to make a slight displacement in a predetermined direction.

[0047] Alternatively, please refer to Figure 3 , Figures 7 to 9 In this embodiment, the wire clamping mechanism is a bird beak wire clamping mechanism 36. The bird beak wire clamping mechanism 36 includes a clamping block 361, a fixed beak 362, a movable beak 363, a first elastic element (not shown in the figure), a first lifting cylinder 364, and a wire clamping push plate 365.

[0048] The clamping block 361 is fixedly installed on the outer periphery of the lower winding shaft 34. The fixed nozzle 362 is fixedly disposed on the clamping block 361. The movable nozzle 363 is rotatably installed on the clamping block 361 and is disposed opposite to the fixed nozzle 362. A clamping opening for clamping the wire 710 is formed between the fixed nozzle 362 and the movable nozzle 363.

[0049] The first elastic element is disposed between the movable mouth 363 and the clamping block 361, and is used to provide a clamping force to the movable mouth 363 toward the fixed mouth 362, so that the movable mouth 363 always has a tendency to close toward the fixed mouth 362 in its natural state.

[0050] The first lifting cylinder 364 is vertically mounted on the lower reference frame 32, and its output end is connected to a wire clamping push plate 365. The wire clamping push plate 365 is located below the movable nozzle 363 and corresponds to the force-receiving part of the movable nozzle 363.

[0051] When wire 710 needs to be clamped, the first lifting cylinder 364 is in a retracted state. Under the action of the first elastic element, the movable nozzle 363 and the fixed nozzle 362 remain closed, thereby reliably clamping the wire 710. When wire 710 needs to be released, the first lifting cylinder 364 extends and drives the wire clamping push plate 365 to move upward. The wire clamping push plate 365 pushes the movable nozzle 363 to rotate around its rotation axis, causing the movable nozzle 363 to overcome the elastic force of the first elastic element and gradually move away from the fixed nozzle 362, thereby opening the clamping opening.

[0052] Specifically, the movable nozzle 363 and the clamping block 361 can be rotatably connected by a pin. The first elastic element can be a torsion spring structure, with the torsion spring sleeved on the outer circumference of the pin and its two ends abutting against the clamping block 361 and the movable nozzle 363 respectively.

[0053] Alternatively, please refer to Figure 2 , Figure 4 and Figure 7 In this embodiment, the number of multiple sets of upper winding shafts 24 is set to ten sets, and they are arranged linearly and symmetrically on the upper reference frame 22 with the first motor 23 as the center.

[0054] Specifically, the first motor 23 is installed in the central area of ​​the upper reference frame 22, and ten sets of upper winding shafts 24 are distributed on both sides of the first motor 23. Five sets of upper winding shafts 24 are located on the left side of the first motor 23, and five sets are located on the right side. The sets of upper winding shafts 24 are arranged at intervals along the same straight line, thus forming a linearly symmetrical arrangement centered on the first motor 23. This arrangement helps to shorten the transmission path, balance the transmission force, and improve the synchronous transmission accuracy and operational stability.

[0055] Understandably, ten sets of upper winding shafts 24 are correspondingly provided with ten sets of lower winding shafts 34, with each set of upper winding shafts 24 and its corresponding lower winding shaft 34 arranged coaxially. When the upper winding mechanism 2 and the lower winding mechanism 3 approach each other, each upper winding shaft 24 is inserted into the insertion slot of its corresponding lower winding shaft 34, thereby forming ten synchronous winding stations and realizing multi-station synchronous winding operations. That is, the ten sets of winding stations can complete the synchronous winding of ten products at one time, significantly improving the production efficiency and capacity utilization of the equipment while ensuring winding consistency.

[0056] It should be understood that setting the upper winding shaft 24 to ten groups in this embodiment is only a preferred implementation. In other embodiments, the number of upper winding shafts 24 can also be set to four, five, six, seven, eight, nine, eleven, twelve or other numbers according to actual production needs. Their arrangement can also be symmetrical, asymmetrical or partitioned. As long as the synchronous driving of multiple winding shafts can be achieved, they should fall within the protection scope of this invention.

[0057] Please refer to Figures 1 to 26 Another aspect of the present invention provides a multi-axis synchronous winding machine 1000, including a wire feeding frame 200, a tension mechanism 300, a wire pressing mechanism 400, a feeding mechanism 600, and a multi-axis synchronous winding device 100 as described above.

[0058] The wire feeding rack 200 is used to carry the wire supply device (not shown in the figure) to deliver the wire 710. Specifically, the wire supply device can be a wire reel, spool, or other wire supply assembly for storing the wire 710. As long as it can deliver multiple parallel wires 710, it is acceptable.

[0059] Tension mechanism 300 is mounted on pay-off frame 200 and is used to apply a predetermined tension to the lead-out wire 710. Specifically, tension mechanism 300 is not an improvement of this application and existing tensioners can be used, which will not be elaborated on here.

[0060] Specifically, in this embodiment, the number of wire supply devices and tension mechanisms 300 arranged at intervals on the wire feeding frame 200 is ten each, to adapt to the multi-axis synchronous winding device 100 with ten sets of upper winding shafts 24 in this embodiment. In other embodiments, the number of wire supply devices and tension mechanisms 300 can also be other, as long as it matches the number of upper winding shafts 24 on the multi-axis synchronous winding device 100, and no specific limitation is made here.

[0061] The wire pressing mechanism 400 is mounted on the frame 1 and located between the tension mechanism 300 and the multi-axis synchronous winding device 100. The wire pressing mechanism 400 is used to guide and press the wire 710 after it has passed through the tension mechanism 300, so that the wire 710 maintains a stable running trajectory and tension state during the conveying and winding process.

[0062] The clamping and cutting mechanism 4 is located between the wire pressing mechanism 400 and the upper winding mechanism 2. It is used to clamp the wire 710 during the winding of the coil 720 and to cut the wire 710 after the coil 720 is wound.

[0063] The feeding mechanism 600 is located downstream of the multi-axis synchronous winding device 100 and is used to feed the coil 720 after the winding is completed.

[0064] Since the multi-axis synchronous winding machine 1000 has all the structures and connections of the multi-axis synchronous winding device 100, it has all the advantages of the multi-axis synchronous winding device 100, which will not be elaborated here.

[0065] Please refer to Figures 10 to 12 In this embodiment, the wire pressing mechanism 400 includes a wire pressing frame 410, ten wire pressing plates 420, ten second elastic elements 430, a second lifting cylinder 440, a top plate 450, ten inlet wire guide rings 460, and ten outlet wire guide rings 470.

[0066] The wire pressing frame 410 is fixedly installed on the frame 1, and ten wire pressing plates 420 are spaced apart on the wire pressing frame 410, each corresponding to one of the ten wires 710. Each wire pressing plate 420 is elastically installed on the wire pressing frame 410 by a second elastic member 430.

[0067] The second lifting cylinder 440 is mounted on the wire pressing frame 410 and is located below the multiple wire pressing plates 420. The piston rod end of the second lifting cylinder 440 is fixedly connected to a top plate 450, which is located below the multiple wire pressing plates 420.

[0068] Ten inlet wire guide rings 460 are disposed on the side of the wire pressing frame 410 near the tension mechanism 300, and ten outlet wire guide rings 470 are disposed on the side of the wire pressing frame 410 near the multi-axis synchronous winding device 100. The inlet wire guide rings 460 and outlet wire guide rings 470 are each corresponding to one of the multiple wires 710, used for guiding and positioning the wires 710.

[0069] During operation, multiple wires 710, derived from the tension mechanism 300, pass through their corresponding inlet guide rings 460 and continue through the gap between the corresponding pressure plate 420 and the top plate 450. At this time, the second lifting cylinder 440 drives the top plate 450 to move upward until the top plate 450 contacts the pressure plate 420. As the top plate 450 continues to rise, the pressure plate 420 applies elastic pressure to the wires 710 under the action of the second elastic element 430, thereby maintaining the wires 710 in a stable tensioned state. Subsequently, they pass through the corresponding outlet guide rings 470 and enter the multi-axis synchronous winding device 100 for winding.

[0070] Specifically, in this embodiment, the inlet wire ring 460 and the outlet wire ring 470 are pigtail rings, and the second elastic element 430 is a compression spring. In other embodiments, the number of inlet wire ring 460, outlet wire, pressure plate 420, and second elastic element 430 can also be other numbers, as long as they match the number of upper winding shafts 24 on the multi-axis synchronous winding device 100.

[0071] Alternatively, please refer to Figures 13 to 17 In this embodiment, the multi-axis synchronous winding machine 1000 includes two clamping and cutting mechanisms 4 symmetrically arranged on the first motor 23 to clamp each of the five groups of wires 710 located on both sides of the first motor 23 during winding and to cut them after winding is completed. Of course, in other embodiments, only one clamping and cutting mechanism 4 may be provided to clamp or cut all the wires 710 simultaneously, and no specific limitation is made here. The specific structure of the clamping and cutting mechanism 4 is described in detail below.

[0072] The clamping and cutting mechanism 4 includes a third linear module 41, a left die cylinder 42, a right die cylinder 43, a left die connecting plate 44, a right die connecting plate 45, multiple left dies 46, multiple right dies 47, and multiple flexible pressure blocks 48.

[0073] The third linear module 41 is mounted on the frame 1 along the conveying direction of the wire 710. The left die-cutting cylinder 42 and the right die-cutting cylinder 43 are fixedly mounted on the output end of the third linear module 41 and are positioned opposite each other. Understandably, the third linear module 41 can also be an existing electric linear module, with the mounting brackets for the left die-cutting cylinder 42 and the right die-cutting cylinder 43 fixed on the movable base of the third linear module 41. The left die-cutting connecting plate 44 is fixedly connected to the piston rod end of the left die-cutting cylinder 42, and the right die-cutting connecting plate 45 is fixedly connected to the piston rod end of the right die-cutting cylinder 43.

[0074] Five left die-cutting dies 46 are disposed on the left die-cutting die connecting plate 44, and five right die-cutting dies 47 are disposed on the right die-cutting die connecting plate 45, with each left die-cutting die 46 corresponding to its corresponding right die-cutting die 47. A flexible pressure block 48 is fixedly disposed on the side of each left die-cutting die 46 facing its corresponding right die-cutting die 47. Optionally, the flexible pressure block 48 may be made of rubber, polyurethane, silicone, or other elastic materials.

[0075] When clamping wire 710, the left die cylinder 42 drives the flexible pressure block 48 to move towards wire 710, and the right die cylinder 43 drives the right die 47 to move closer to the flexible pressure block 48, thereby clamping wire 710 between the flexible pressure block 48 and the right die 47. The third linear module 41 can drive the clamping and cutting mechanism 4 to move along the wire 710 conveying direction to adjust the relative position between wire 710 and the clamping mechanism.

[0076] After the winding is completed, the left die cylinder 42 and the right die cylinder 43 drive the left die 46 and the right die to move towards each other, so that the wire 710 is located between the left die 46 and the right die and is cut off, thereby realizing the separation of the coil 720 and the wire 710.

[0077] Understandably, the number of left die 46 on the left die connecting plate 44 and the number of right die on the right die connecting plate 45 correspond to specific wire 710 settings.

[0078] Because cable 710 is a self-adhesive enameled wire. Optionally, please refer to... Figures 17 to 20 In this embodiment, the multi-axis synchronous winding machine 1000 further includes a heating and shaping mechanism 500. The heating and shaping mechanism 500 is disposed on the frame 1 and located on one side of the multi-axis synchronous winding device 100, and is used to perform online heating treatment on the wire 710 during the winding process and to achieve winding shaping.

[0079] Specifically, the heating and shaping mechanism 500 includes: a support frame 510, a drive cylinder 520, a mounting plate 530, and multiple heating heads 540. The support frame 510 is fixedly mounted on the frame 1. The drive cylinder 520 is mounted on the support frame 510, and its piston rod end is fixedly connected to the mounting plate 530, used to drive the mounting plate 530 closer to or further away from the winding position.

[0080] Multiple heating heads 540 are fixed at intervals on the mounting plate 530. Specifically, there are ten heating heads 540, corresponding one-to-one with the upper winding shaft 24 of the multi-axis synchronous winding device 100, so that each heating head 540 can correspond to different winding positions and achieve synchronous heating of multiple sets of wires 710. Optionally, the air inlet pipe of the heating head 540 is connected to an external heat source (not shown in the figure) to spray hot air.

[0081] When the multi-axis synchronous winding device 100 is ready for winding, the drive cylinder 520 pushes the mounting plate 530 and its multiple heating heads 540 to the winding area, bringing the heating heads 540 close to the winding position. At the start of winding, the heating heads 540 continuously heat the wire 710. During heating, the self-adhesive coating on the surface of the self-adhesive enameled wire melts, achieving online self-adhesion between turns. This allows the coil 720 to simultaneously complete bonding and shaping during winding, releasing winding stress. After winding is complete, the drive cylinder 520 reverses its direction, moving the mounting plate 530 and heating heads 540 away from the winding position, exiting the working state, and awaiting the next working cycle.

[0082] Alternatively, please refer to Figure 1 , Figure 6 , Figures 21 to 26 In this embodiment, the feeding mechanism 600 includes: a stripping component 610, a coil transfer component 620, and a coil receiving component 631.

[0083] The unloading assembly 610 includes an unloading cylinder 611, an unloading push plate 612, and multiple unloading bushings 613. The unloading cylinder 611 is fixedly mounted on the upper reference frame 22, and its piston rod end is connected to the unloading push plate 612. Multiple unloading bushings 613 are fixed at intervals to the bottom end of the unloading push plate 612 and are respectively sleeved on the outer circumference of each upper winding shaft 24, used to push the wound coil 720 out during the unloading process.

[0084] The coil transfer assembly 620 includes a fourth linear module 621, a slide rail 622, a flipping frame 623, a rotary cylinder 624, a rotary shaft 625, a feeding cylinder 626, a feeding push plate 627, and multiple sets of stripping blocks 628 and stripping shafts 629. The fourth linear module 621 is mounted on the frame 1 and is positioned opposite the slide rail 622. It drives the flipping frame 623 to move between a receiving position below the upper winding mechanism 2 and a feeding position away from that receiving position. Specifically, the fourth linear module 621 is also a conventional electric linear module.

[0085] A tilting frame 623 is positioned across the output end of the fourth linear module 621 and the slide rail 622. A rotary cylinder 624 is mounted on the tilting frame 623, and its output end is driven by a rotating shaft 625 to drive the rotating shaft 625 to rotate. A feeding cylinder 626 is fixed to the rotating shaft 625, and its piston rod end is fixedly connected to a feeding push plate 627. Multiple sets of stripping blocks 628 and stripping shafts 629 are correspondingly arranged on the feeding push plate 627.

[0086] Specifically, each stripping shaft 629 is movably mounted on the corresponding stripping block 628 via a third elastic element 630, giving the stripping shaft 629 a certain buffering and self-adaptive capability when contacting the coil 720, thereby avoiding damage to the coil 720. Specifically, the third elastic element 630 is also a compression spring.

[0087] The coil receiving assembly 631 is located at the unloading position of the frame 1 and below the flipping frame 623, and is used to receive the coil 720 after unloading.

[0088] During operation, after the upper winding mechanism 2 completes the winding operation, the lower winding mechanism 3 moves downward to move away from the upper winding mechanism 2. The fourth linear module 621 drives the coil transfer assembly 620 to move directly below the upper winding mechanism 2, so that the unloading assembly 610 is aligned with the corresponding position of the upper winding shaft 24.

[0089] At this time, the stripping shaft 629 and the upper winding shaft 24 are docked and positioned. The stripping cylinder 611 is activated, which drives the stripping push plate 612 to move downward, so that the stripping shaft sleeve 613 pushes the product coil 720 wound on the upper winding shaft 24, thereby detaching the coil 720 from the upper winding shaft 24 and transferring it to the corresponding stripping shaft 629.

[0090] After unloading, the upper winding mechanism 2 rises, so that the coil 720 is sleeved on the unloading shaft 629, and is carried and moved to the unloading position by the coil transfer assembly 620. Then, the rotary cylinder 624 drives the rotary shaft 625 to rotate 180°, and the unloading cylinder 626 pushes the unloading push plate 627 downward, so that the unloading block 628 pushes the product coil 720 located on the unloading shaft 629, thereby detaching the coil 720 from the unloading shaft 629. Finally, the coil receiving assembly 631 completes the receiving, realizing the automated transfer and unloading of the coil 720.

[0091] Specifically, the coil receiving component 631 can be implemented using existing mature structural forms. Its specific structure and operation are not improvements of this application, so they will not be elaborated on here.

[0092] Optionally, the multi-axis synchronous winding machine 1000 also includes a control mechanism (not shown in the figure). This control mechanism is electrically connected to the first linear module 21, the first motor 23, the second linear module 31, the second motor 33, the first lifting cylinder 364, the third linear module 41, the left die cylinder 42, the right die cylinder 43, the tension mechanism 300, the second lifting cylinder 440, the drive cylinder 520, the stripping cylinder 611, the fourth linear module 621, the rotary cylinder 624, the unloading cylinder 626, and the coil receiving assembly 631. It controls the aforementioned actuators to operate collaboratively according to a preset program to complete winding, clamping, cutting, heating and shaping, stripping, and unloading processes. Specifically, the control mechanism can be implemented using existing mature control systems. Its specific structure and control logic are conventional techniques for those skilled in the art and are not improvements in this application; therefore, they will not be elaborated upon here.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the substance of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
