The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0053] First embodiment

[0054] 1 and 2 , a coil winding device according to a first embodiment of the present invention includes:

[0055] A bending mechanism 300 is used to bend the conductive wire 2000 to obtain the coil 210 constituting the winding 200 , wherein the discharging port of the bending mechanism 300 is arranged downward;

[0056] The winding bracket 100 is used to support the winding 200 after being bent by the bending mechanism 300. The winding bracket 100 includes a winding tray 110 and a winding fixing seat 121.

[0057] The adjustment mechanism 400 is used to adjust the position of the wire 2000 in the winding bracket 100 . The adjustment mechanism 400 includes a clamping arm 430 and a clamping member 410 fixed on the clamping arm 430 for clamping the winding 200 .

[0058] The bending mechanism 300 can bend the wire 2000 in sequence along a predetermined trajectory to form each layer of coil 210 of the winding 200. After the bending mechanism 300 completes winding a coil 210, the adjustment mechanism 400 can adjust the position of the wire 2000 in the winding bracket 100, so that when the coil of the next winding 200 is wound, the previously wound winding 200 will not interfere with it, thereby ensuring the winding quality of each winding 200 and realizing automated winding.

[0059] Specifically, the coil winding equipment also includes a bracket motion assembly 500, which is used to install the winding bracket 100 and drive the winding bracket 100 to complete translation and rotation. The bracket motion assembly 500 includes a translation assembly 510 and a rotation assembly 520. The translation assembly 510 can drive the winding bracket 100 to translate in the X, Y, and Z directions, and the rotation assembly 520 can drive the winding bracket 100 to rotate around the Z axis.

[0060] As shown in FIG. 2 and FIG. 3 , a wire lifting plane 110 a is provided on the winding tray 110 , and the overall height of the winding fixing seat 121 is lower than the wire lifting plane 110 a .

[0061] The winding tray 110 includes a tray transverse plate 111 and a tray vertical plate 112. The tray vertical plate 112 can be supported on the lower surface of the tray transverse plate 111 to form a wire lifting plane 110a on the upper surface of the tray transverse plate 111. The overall height of the winding fixing seat 121 is lower than the wire lifting plane 110a. Therefore, when the bending mechanism 300 bends the wire 2000 to form a coil 210, the bent coil 210 can be directly supported on the wire lifting plane 110a without being affected by the winding fixing seat 121, etc., thereby improving the winding quality of the winding 200.

[0062] Preferably, the tray transverse plate 111 of the winding tray 110 is circumferentially unobstructed to prevent obstructions from affecting the tray transverse plate 111 supporting the winding during winding, thereby further improving the winding quality of the winding 200 .

[0063] As shown in Figures 2 and 3, there are multiple winding fixing seats 121, and the height of the multiple winding fixing seats 121 decreases in a step-by-step manner from the first level to the last level. The first level of the winding fixing seat 121 is adjacent to the winding tray 110. The winding tray 110 and the first to last level of the winding fixing seats can be connected end to end in a ring arrangement, making the structure compact and improving the stability of the structure.

[0064] Furthermore, the winding bracket 100 further includes a base 140 for mounting and fixing the winding tray 110 and the winding fixing seat 121. The winding tray 110 and the winding fixing seat 121 are circumferentially arranged and fixed to the base 140 along a virtual centerline 1000. Specifically, the base 140 may be annular, and the virtual centerline 1000 may be located on the centerline of the base 140. That is, the multiple winding fixing seats 121 are arranged circumferentially along the centerline of the base 140 to accommodate the multiple circumferentially arranged coils 210 of the winding 200.

[0065] 3 , the winding 200 includes a plurality of coils 210 and bridge wires 220 connecting two adjacent coils 210 . The plurality of coils 210 are arranged circumferentially. The winding tray 110 is used to support the wound coils 210 in the winding 200 , while the plurality of winding holders 121 are used to respectively place the wound coils 210 in the winding 200 , with each winding holder 121 corresponding to a respective coil 210 .

[0066] Furthermore, the winding tray 110 and the plurality of fixing base bottom plates 122 are sequentially arranged in a circumferential spiral staircase along the virtual center line 1000 from top to bottom.

[0067] In the winding bracket 100, the tray transverse plate 111 of the winding tray 110 is at the highest level to support the coil 210 being wound on the tray transverse plate 111. The level of the fixing seat bottom plates 122 of the plurality of winding fixing seats 121 decreases in circumferential direction along the virtual center line 1000 to accommodate the coils 210 of the winding 200 that have been wound.

[0068] Multiple winding fixing seats 121 are divided into the first to Nth winding fixing seats, and the horizontal heights of the first to Nth winding fixing seats decrease circumferentially along the virtual center line 1000, wherein the winding tray 110 and the first to Nth winding fixing seats can be connected end to end in sequence to form a ring arrangement, making the structure compact and improving the stability of the structure.

[0069] The first winding fixing seat is lower than the tray transverse plate 111 of the winding tray 110, and the height difference between the first winding fixing seat 121 and the tray transverse plate 111 is no less than the height of the coil 210. Due to the height difference between the first winding fixing seat 121 and the tray transverse plate 111, the coil 210 of the wound winding 200 has a decreasing height to fit on the fixing seat bottom plates 122 of the first to Nth winding fixing seats, which have successively decreasing heights.

[0070] As shown in Figure 2, the winding fixing seat 121 includes a fixing seat bottom plate 122 and a fixing vertical plate 1202. The wound coil 122 is supported on the upper surface of the fixing seat bottom plate 122. The fixing vertical plate 1202 can be supported and connected to the lower surface of the fixing seat bottom plate 122. The fixing seat bottom plate 122 can be directly fixed on the base 140, or fixed on the fixing seat bottom plate 122 of the next winding fixing seat 121.

[0071] As shown in Figures 2 and 3, a limiting assembly 130 is provided on the base plate 122 of the winding fixing seat 121. The limiting assembly 130 is used to position the coil 210. This prevents the coil 210 wound on the winding fixing seat 121 from affecting the winding tray 110 in supporting the coil 210 being wound. It also prevents the coil 210 from being separated from the winding bracket 100 due to the centrifugal force caused by the rotation of the winding bracket 100.

[0072] Specifically, the limiting assembly 130 includes a circumferential stopper 131 and a radial stopper 132. The circumferential stopper 131 is arranged on the side surface of the fixing seat base plate 122 along the circumferential direction of the virtual center line 1000, and the radial stopper 132 is arranged on the outer side surface of the fixing seat base plate 122 along the radial direction of the virtual center line 1000.

[0073] Any point of the fixing seat bottom plate 122 , the circumferential stopper 131 , and the radial stopper 132 is lower than the horizontal height of the upper end plane of the tray transverse plate 111 .

[0074] The winding tray 110 is used to support the winding 200 being wound, and the winding fixing seat 121 is used to fix the wound winding 200. The winding fixing seat 121 includes a fixing seat bottom plate 122, a circumferential stop block 131 and a radial stop block 132, which improves the stability of fixing the wound winding 200. At the same time, any point of the fixing seat bottom plate 122, the circumferential stop block 131 and the radial stop block 132 is lower than the horizontal height of the upper end plane of the tray cross plate 111, so it will not affect the winding of the winding 200 on the winding tray 110, thereby improving the winding quality of the winding 200.

[0075] As shown in FIG. 2 , the winding fixing seat 121 is provided with an adjustment hole 1200 , and the circumferential stopper 131 can slide in the adjustment hole 1200 .

[0076] The adjustment holes 1200 are arranged circumferentially to allow the circumferential stopper 131 to be adjusted in position, thereby adjusting the accommodation space of the coil 210. The circumferential stopper 131 can be connected by screws passing through the adjustment holes 1200 so that the circumferential stopper 131 can slide within the adjustment holes 1200, and then the position can be fixed by retracting the screws.

[0077] 2 , the top side surface of the circumferential stopper 131 facing the coil 210 is chamfered to facilitate the transfer mechanism to pass through and insert into the coil 210, and to facilitate the displacement of the coil 210. The top side surface of the radial stopper 132 facing the coil 210 may also be chamfered.

[0078] As shown in FIG2 , the winding tray 110 and multiple fixing seat base plates 122 are arranged in a circumferential spiral staircase from top to bottom along the virtual center line 1000, wherein the last fixing seat base plate 122 can be integrally connected to the base 140, and a circumferential stopper 131 and a radial stopper 132 are provided thereon.

[0079] 6 , the bending mechanism 300 includes a bending motor 320 and a bending jig 310. The bending motor 320 is connected to the bending jig 310 through gears, etc., and the bending motor 320 drives the bending jig 310 to rotate. The shape of the bending jig 310 defines the shape of the coil 210. The coil 210 can be trapezoidal or fan-shaped. The wire 2000 is delivered to the bending jig 310 of the bending mechanism 300 by the wire feeding mechanism 600, and the winding bracket 100 is driven to move by the translation assembly 510 so that the bending jig 310 is located on the winding bracket 100. , and then the bending motor 320 drives the bending jig 310 to rotate once, that is, the bending jig 310 bends the wire 2000 once to form the first layer of the coil 210. Then, the bracket Z-moving member 513 of the bracket moving assembly 510 drives the winding bracket 100 to move downward, wherein the discharge port of the bending mechanism 300 is arranged downward, so that the first layer of the coil 210 falls on the winding tray 110 under the action of gravity, and this cycle is repeated to complete the second to last layers of the coil 210. At this time, the coil 210 is wound from bottom to top.

[0080] Referring to FIG1 , further, the tail end of the wire 2000 is located at the wire feeding mechanism 600, and the head end of the wire 2000 can be clamped by a robot, etc., wherein the robot and the wire feeding mechanism 600 are located on both sides of the bending jig 310. At this time, the wire 2000 is located on one side of the bending jig 310, and the bending jig 310 is rotated once to bend the wire 2000 to form a layer of the coil 210. Then the robot Release, and the bracket Z-moving member 513 of the bracket moving assembly 510 drives the winding bracket 100 to move downward, so that the first layer of the coil 210 falls on the winding tray 110 under the action of gravity, and then the bending jig 310 remains in place to wind the second layer of the coil 210, and then the bracket Z-moving member 513 of the bracket moving assembly 510 drives the winding bracket 100 to move downward again until the winding of the coil 210 is completed.

[0081] As shown in Figure 1, the wire feeding mechanism 600 includes at least one roller group 610, and the roller group 610 includes several rollers 611. The several rollers 611 are arranged on both sides of the wire 2000, and the rollers 611 on both sides of the wire 2000 can be staggered. By setting the rollers 611, not only the stability of the wire 2000 transportation is improved, but also the wire feeding direction of the wire 2000 is limited. For example, the wire 2000 is transported to the side of the bending jig 310 along the X-axis direction.

[0082] When there are two roller groups 610 , the two roller groups 610 are arranged vertically, for example, the rollers 611 of the two roller groups 610 are perpendicular to each other.

[0083] As shown in Figures 1 and 6, the adjustment mechanism 400 includes at least one clamping member 410, which is configured to be inserted into the coil 210 and to open and contract. When the clamping member 410 is opened, the clamping member 410 is tightly against the inner side of the coil 210.

[0084] The shape of the clamping member 410 is adapted to the shape of the coil 210 and can be inserted into the coil 210. The bottom of the clamping member 410 can be provided with a chamfered surface to facilitate the insertion and removal of the clamping member 410 into and from the coil 210.

[0085] The clamping member 410 includes two clamping blocks 411, one of which is driven by a cylinder 420. When the cylinder drives one clamping block 411 away from the other clamping block 411, the clamping member 410 opens; when the cylinder drives one clamping block 411 toward the other clamping block 411, the clamping member 410 contracts.

[0086] Therefore, when the clamping member 410 is inserted into the coil 210 and opens, the clamping member 410 is tightly against the inner side of the coil 210, and the coil 210 can be moved to prevent the coil 210 from falling during the movement. When the clamping member 410 is inserted into the coil 210 and retracts, the tight contact between the clamping member 410 and the inner side of the coil 210 is released, and the clamping member 410 can be detached from the coil 210.

[0087] 6 , each of the clamping members 410 moves the coil 210 on the winding tray 110 to the first-level winding fixing seat 121 , and moves the coil 210 on the current winding fixing seat 121 to the next winding fixing seat 121 .

[0088] As shown in Figure 6, the adjustment mechanism 400 also includes a clamping member mounting plate 440, and there are multiple clamping members 410. The multiple clamping members 410 are installed on the clamping member mounting plate 440, and the horizontal height of the bottom surface of each clamping member 410 decreases in a step-by-step manner from the first level to the last level, so that the height of the clamping member 410 corresponds to the height of the winding tray 110 and the winding fixing seat 121.

[0089] The arrangement of the clamping members 410 is affected by the arrangement of the winding tray 110 and the winding fixing seat 121, wherein the multiple clamping members 410 are arranged circumferentially and correspond to the circumferential arrangement of the winding tray 110 and the multiple windings 200, that is, the horizontal height of the bottom surface of each clamping member 410 decreases step by step from the first level to the last level.

[0090] As shown in FIG1 , FIG6 and FIG7 , the translation assembly 510 includes a bracket X-direction moving member 511 , a bracket Y-direction moving member 512 and a bracket Z-direction moving member 513 ;

[0091] The bracket Z-direction moving member 513 is connected to the bracket X-direction moving member 511, and can drive the bracket X-direction moving member 511 to move along the Z direction. The bracket X-direction moving member 511 is connected to the bracket Y-direction moving member 512, and can drive the bracket Y-direction moving member 512 to move along the X direction. The bracket Y-direction moving member 512 is connected to the winding bracket 100, and can drive the winding bracket 100 to move along the Y direction. The shapes of the bracket X-direction moving member 511, the bracket Y-direction moving member 512 and the bracket Z-direction moving member 513 can be the same, for example, they all include a motor, a screw and a guide rail, and the bracket Z-direction moving member 513 can be driven to rise and fall by hydraulic pressure. In addition, the positions of the bracket X-direction moving member 511, the bracket Y-direction moving member 512 and the bracket Z-direction moving member 513 can be interchangeable, for example, the bracket Z-direction moving member 513 is arranged between the winding bracket 100 and the bracket Y-direction moving member 512.

[0092] As shown in Figure 7, the rotating assembly 520 includes a base 521, a rotating seat 522 and a rotating motor 523. The rotating seat 522 is rotatably installed on the base 521, and the rotating motor 523 drives the rotating seat 522 to rotate. The base 521 is installed on the translation assembly 510, and the winding bracket 100 is installed on the rotating seat 522.

[0093] The rotating motor 523 can be connected to the rotating base 522 via a pulley, gears, etc., so that the rotating motor 523 drives the winding bracket 100 connected to the rotating base 522 to rotate. The rotating assembly 520 drives the winding bracket 100 to rotate eccentrically relative to the virtual center line 1000, or the rotating assembly 520 drives the winding bracket 100 to rotate around the virtual center line 1000, which can be selected according to design requirements.

[0094] 1 and 7 , the coil winding apparatus further comprises a workbench 700, on which the carriage moving assembly 510 and the bending mechanism 300 can be fixed. The workbench 700 can be constructed from sheet metal 710, profiles 720, and feet 730. There can be two workbench 700, and the two workbench 700 can be at different heights. The carriage moving assembly 510 can be fixed to a workbench 700 at a lower height, and the bending mechanism 300 can be fixed to a workbench 700 at a higher height, so that the bending mechanism 300 connected to the carriage moving assembly 510 is located above the winding carriage 100.

[0095] As shown in FIG1 and FIG6 , the clamping arm 430 includes a clamping X-direction moving member 431 , a clamping Y-direction moving member 432 , and a clamping Z-direction moving member 433 ;

[0096] Said clamping Y direction moving member 432 is connected with said clamping X direction moving member 431, can drive said clamping X direction moving member 431 to move along the Y direction, said clamping X direction moving member 431 is connected with said clamping Z direction moving member 433, can drive said clamping Z direction moving member 433 to move along the X direction, said clamping Z direction moving member 433 is connected with said clamping member 410, can drive said clamping member 410 to move along the Z direction.The shape of said clamping X direction moving member 431, clamping Y direction moving member 432 and clamping Z direction moving member 433 can be identical, for example, all comprise motor, lead screw and guide rail etc., and three's position also can be interchangeable.With reference to Figure 6, said clamping Y direction moving member 432 is fixed on the said bending mechanism 300, so that is connected to the adjustment mechanism 400 on the said clamping moving assembly 520, it can remain on the top of said winding carriage 100.

[0097] In summary, the bending mechanism 300 can sequentially wind the wire 2000 into the coils 210 of the winding 200 and reserve a bridge wire 220 between two adjacent coils 210. The wire 2000 can be a flat copper wire or a round copper wire, preferably a flat copper wire. When the bending mechanism 300 completes winding a coil 210 and the wound coil 210 is supported on the winding tray 110 of the winding bracket 100, the bracket motion assembly 500 drives the winding bracket 100 to move, and the clamping arm 430 drives the clamping member 410 to move, so that the clamping member 410 moves the coil 210 wound on the winding tray 110 to the winding fixing seat 121, and then the bending mechanism 300 winds the next coil 210 of the winding 200 on the winding tray 110, and the coil fixed on the winding fixing seat 121 will not affect the winding of the next coil 210 on the winding tray 110, thereby ensuring the winding quality of the winding 200 and realizing automatic winding.

[0098] Second embodiment

[0099] As shown in Figures 4 and 5, the winding bracket of the second embodiment is different from the first embodiment in that the winding bracket also includes a winding placement position 1300, which is used to place the wound winding 200, and at least one of the winding fixing seats 121 is adjacent to the winding tray 110.

[0100] The number of winding holders 121 can be one, and the winding tray 110 is located on one side of the winding holder 121 along the circumference of the virtual centerline 1000. The winding tray 110 is adjacent to the winding holder 121, and the winding placement position 1300 is located on the other side of the winding holder 121 along the circumference of the virtual centerline 1000. Only the coils 210 adjacent to the winding machine are fixed by the winding holder 121, while the remaining coils 210 are freely placed on the winding placement position 1300 (see Figure 4). In addition to fixing the coils 210 to prevent them from affecting the winding of the windings 200 on the winding tray 110, the winding holder 121 also prevents the freely placed coils from swinging and affecting the winding quality.

[0101] Third embodiment

[0102] As shown in Figures 1 to 3, the coil winding method in the third embodiment of the present application is as follows:

[0103] 10) A coil 210 winding step, wherein the conductive wire 2000 is bent by the bending mechanism 300 to obtain the coil 210;

[0104] 20) A step of reserving a bridge wire intermediate body 221 , reserving a bridge wire intermediate body 221 on one side of the wound coil 210 by means of a bending mechanism 300 ;

[0105] 30) Repeat the above steps 10) and 20) to obtain a structure in which multiple coils 210 are connected to each other through the bridge wire intermediate body 221;

[0106] 40) The bridge wire 220 shaping step is to deform the bridge wire intermediate body 221 so that the end surfaces of both sides of the plurality of coils 210 are flush.

[0107] The winding 200 includes coils 210 and bridge wires 220. The bridge wires 220 include a plurality of bridge wire intermediates 221, each of which connects between two adjacent coils 210. As can be seen from steps 10) to 30), the winding 200 is continuously and integrally wound, using automated winding. In step 40), the bridge wires 220 are shaped to ensure that the end faces of each coil 210 of the winding 200 are flush. This ensures that the winding 200 can be assembled on the stator of an axial flux motor, with each coil 210 being mounted on a tooth segment of the stator.

[0108] Referring to Figure 3 , the coil 210 is spiral-shaped and is divided into multiple layers or turns from the lower end face to the upper end face. Each layer of the coil 210 has the same shape, such as a trapezoid or fan shape. Because the trapezoid or fan shape has four corners, the bending mechanism 300 needs to bend the wire 2000 four times to complete the winding of each layer of the coil 210. The bending angle is determined by the shape and size of each layer of the coil 210.

[0109] As shown in Figure 1 , the bending mechanism 300 bends the conductive wire 2000 to form a coil 210. The conductive wire 2000 can be a flat copper wire or a round copper wire, preferably a flat copper wire. The coil 210 is wound from bottom to top, and the discharge port of the bending mechanism 300 is positioned downward. Therefore, in step 10), the bottom of the coil 210 is initially formed and then spirally ascends to the top of the coil 210. The coil 210 is discharged vertically downward while being supported by the winding tray 110 of the winding bracket 100 located below the bending mechanism 300.

[0110] Referring to Figure 1 , the wire 2000 is fed by the wire feeding mechanism 600 to the bending mechanism 300 . Since each layer of the coil 210 is trapezoidal, with four sides and four corners, during the winding process of each layer of the coil 210, the wire feeding mechanism 600 feeds the wire 2000 four times at intervals, corresponding to the four sides of each layer of the trapezoid. In between the four wire feedings by the wire feeding mechanism 600, the bending mechanism 300 bends the wire 2000 to form the four corners of the trapezoid. That is, after the wire feeding mechanism 600 feeds the wire 2000 once, the bending mechanism 300 immediately bends the wire 2000 once, and this cycle continues until the winding of each layer of the coil 210 is complete.

[0111] In the winding of each layer of the coil 210 , parameters such as the wire feeding length of the wire feeding mechanism 600 and the bending angle of the bending mechanism 300 are determined according to the shape and size of each layer of the coil 210 .

[0112] 1 to 3 , in step 10 , the coil 210 being wound is lifted by the winding tray 110 of the winding bracket 100 . The lower end surface of the coil 210 abuts against the winding tray 110 .

[0113] It should be noted that before winding each layer of the coil 210, the winding bracket 100 is moved down the distance required for winding each layer of the coil 210. The distance required for winding each layer is the height of each layer of the coil 210. Therefore, the next layer can be wound on the layer where the coil 210 is wound, and the coil 210 can be always supported by the winding tray 110 during the winding process. It can be seen that the coil 210 is wound from bottom to top.

[0114] 1 and 7 , the winding bracket 100 is mounted on a bracket motion assembly 500, and the bracket motion assembly 500 drives the winding bracket 100 to rotate vertically, left-right, front-back, and around the vertical direction, so that the winding bracket 100 is offset vertically, left-right, front-back, and rotated around the vertical direction relative to the bending mechanism 300 to cooperate with the execution of step 10).

[0115] Taking the trapezoidal coil 210 as an example, referring to FIG3 , a right corner 212 is provided between the lower base 213 and the right waist 211 of each layer of the coil 210, and a left corner 214 is provided between the lower base 213 and the left waist 215. While the bending mechanism 300 bends the wire 2000 to form the right corner 212, the bracket motion assembly 500 drives the winding bracket 100 to rotate so that the wire 2000 subsequently delivered by the wire feeding mechanism 600 can correspond to the direction of the lower base 213. Afterwards, the wire feeding mechanism 600 delivers the wire 2000 of the required length to the lower base 213. At the same time, the bracket motion assembly 500 drives the winding bracket 100 to move horizontally so that the wire 2000 delivered by the wire feeding mechanism 600 falls on the position formed on the lower base 213 until the bending mechanism 300 bends the left corner 214.

[0116] From the above, it can be seen that the wire feeding movement of the wire feeding mechanism 600 and the movement of the winding bracket 100 are synchronized, and the rotation of the winding bracket 100 and the bending movement of the bending mechanism 300 are also synchronized, so that the wire feeding and the wound coil 210 follow the bending movement to complete the winding of the winding 200. Compared with the existing technology of manual lifting or hand carrying, it avoids the inability to ensure the synchronization of movement and the inability to ensure the correct shape of the coil 210, and even the deformation of the wound coil 210. It also has the disadvantages of high working intensity and easy fatigue. By using the bracket movement component 500 to drive the winding bracket 100 to move and rotate, the wound coil 210 can be synchronized with the wire feeding movement of the wire feeding mechanism 600 and the bending movement of the bending mechanism 300, thereby ensuring the consistency of the quality of the winding 200 and the production efficiency.

[0117] In the step 20), the wire feeding mechanism 600 transports the wire 2000 of the required length for the bridge wire intermediate 221. During this process, the bending mechanism 300 does not perform bending, but can drive the winding bracket 100 to move through the bracket motion assembly 500 and be opposite to the adjustment mechanism 400, so that in the step 25), the adjustment mechanism 400 moves the coil 210 wound on the winding tray 110 to the winding fixing seat 121 of the winding bracket 100, so as to make room for the winding tray 110 for winding the next coil 210.

[0118] As shown in Figures 1 to 3, the winding method also includes: 25) a step of adjusting the position of the coil 210 and the middle 221 of the bridge wire, and adjusting the position of the coil 210 and the middle 221 of the bridge wire on the winding bracket 100 by the adjustment mechanism 400 before repeating step 10).

[0119] It is further explained that the winding bracket 100 will move and rotate under the drive of the bracket motion component 500, so the wound coil 210 will be subjected to centrifugal force and inertial force during the continuous movement of the winding bracket 100. It can be seen that the wound coil 210 is moved down and fixed on the winding fixing seat 121 to ensure that the wound coil 210 does not swing or other displacement phenomena under the action of these forces, thereby avoiding deformation of the winding 200 and ensuring the quality of the winding 200.

[0120] As shown in FIG1 to FIG3, the horizontal heights of the winding tray 110 and the winding fixing seat 121 decrease in a step-by-step manner. The winding 200 on the winding bracket 100 can be moved by the adjustment mechanism 400. The adjustment mechanism 400 can be a clamping member. Then, step 25) includes:

[0121] 251) clamping the winding 200 on the winding bracket 100 by the adjustment mechanism 400;

[0122] 252) The winding 200 clamped by the adjustment mechanism 400 is moved down one step as a whole, and then the coil 210 wound on the winding tray 110 is moved and fixed on the winding fixing seat 121 of the winding bracket 100, and the coil 210 fixed on the original winding fixing seat 121 is moved out of the original winding fixing seat 121 to the next winding fixing seat 121 or other positions.

[0123] With reference to Figures 4 and 5 , the "other" positions refer to winding placement positions 1300. There may be only one winding holder 121. The winding tray 110 is located on one side of the winding holder 121 along the circumference of the virtual centerline 1000. The winding tray 110 is adjacent to the winding holder 121, and the winding placement position 1300 is located on the other side of the winding holder 121 along the circumference of the virtual centerline 1000. Only the coils 210 adjacent to the winding machine are secured by the winding holder 121, while the remaining coils 210 are free-standing on the winding placement position 1300 (see Figure 5 ). In addition to securing the coils 210 to prevent them from interfering with the winding of the windings 200 on the winding tray 110, the winding holder 121 also prevents the free-standing windings from swinging and affecting the winding quality.

[0124] In step 251), the adjustment mechanism 400 includes a clamping arm 430 and a clamping member 410 fixed on the clamping arm 430 for clamping the winding, and the clamping arm 430 is used to drive the clamping member 410 to translate in the X, Y, and Z directions. The winding bracket 100 is driven by the translation component 510 of the bracket motion component 500 and translates in the X, Y, and Z directions so that the adjustment mechanism 400 can correspond to the winding bracket 100.

[0125] As shown in FIG1 and FIG6 , the adjustment mechanism 400 includes a plurality of clamping members 410 , and the bottom surfaces of the plurality of clamping members 410 decrease in height from the first level to the last level in a stepwise manner, and then the step 251) includes:

[0126] The plurality of clamping members 410 arranged in a stepped manner correspond to the winding trays 110 and the winding fixing seats 121 arranged in a stepped manner, wherein the first-level clamping members 410 correspond to the winding trays 110;

[0127] The corresponding winding tray 110 and the coil 210 on the winding fixing seat 121 are clamped by a plurality of clamping members 410 .

[0128] The clamping members 410 are driven to move by the clamping arms 430, and the winding bracket 100, which is composed of the winding tray 110 and the winding fixing seat 121, is driven to move by the translation assembly 510. When the multiple clamping members 410 arranged in a stepped manner correspond to the stepped winding trays 110 and the winding fixing seats 121, that is, the first-level clamping members 410 correspond to the winding tray 110, and the second-level clamping members 410 correspond to the first-level winding fixing seats 121. At this time, the first-level clamping members 410 clamp the coil 210 on the winding tray 110, and the second-level clamping members 410 clamp the coil on the first-level winding fixing seat 121, and so on.

[0129] 5 , the two clamping blocks 411 are driven by the cylinder 420 to move closer or farther away, and then in step 251):

[0130] Insert the two clamping blocks 411 close to each other into the coil 210;

[0131] The two clamping blocks 411 are driven away by the cylinder 420 so that the clamping member 410 is tightly pressed against the inner side of the coil 210 , thereby completing the clamping operation of the coil 210 by the clamping member 410 .

[0132] As shown in FIG. 1 and FIG. 7 , step 252) includes:

[0133] Move the winding bracket 100 downward along the Z direction so that the winding bracket 100 and the winding 200 clamped by the adjustment mechanism 400 are separated in the height direction;

[0134] The winding bracket 100 is moved in the X and Y directions, and the winding bracket 100 is rotated in the Z direction, so that the plurality of clamping members 410 and the stepped winding tray 110 and the winding fixing seat 121 are staggered by one step, wherein the first-level clamping member 410 is opposite to the winding fixing seat 121;

[0135] The winding 200 clamped by the clamping member 410 is released onto the winding tray 110 and the winding fixing seat 121 .

[0136] The horizontal heights of the clamping members 410 from the first level to the last level decrease in the counterclockwise direction when viewed from above, and the horizontal heights of the winding tray 110 and the winding fixing seat 121 decrease in the clockwise direction when viewed from above. The winding bracket 100 can be rotated counterclockwise by a circumferential angle corresponding to one step, so that the multiple clamping members 410 and the stepped winding tray 110 and the winding fixing seat 121 are staggered by one step, and the first-level clamping members 410 are changed from being opposite to the winding tray 110 to being opposite to the first-level winding fixing seat 121, and the second-level supporting members 410 are changed to being opposite to the second-level winding fixing seat 121.

[0137] As shown in FIG2 and FIG3, the winding fixing seat 121 includes a fixing seat bottom plate 122, and a circumferential stopper 131 and a radial stopper 132 provided on the fixing seat bottom plate 122. In the step 252):

[0138] The coil 210 is placed on the fixing base bottom plate 122 and is confined between the circumferential stopper 131 and the radial stopper 132 .

[0139] The circumferential stoppers 131 and radial stoppers 132 are provided to position the coil 210. This prevents the coil 210 wound on the winding holder 121 from interfering with the winding tray 110 supporting the coil 210 being wound, and also prevents the coil 210 from being separated from the winding bracket 100 due to centrifugal force caused by the rotation of the winding bracket 100.

[0140] As shown in Figures 2 and 3, the circumferential stopper 131 is fixed to one side of the winding fixing seat 121 along the circumference of the virtual centerline 1000, and the tray vertical plate 112 or the fixed vertical plate 1202 is fixed to the other side of the winding fixing seat 121 along the circumference of the virtual centerline. This ensures that the coil 210 on the first winding fixing seat is circumferentially limited between the circumferential stopper 131 on the first winding fixing seat and the tray vertical plate 112 of the winding tray 110, and the coils 210 on the second to last winding fixing seats are circumferentially limited between the circumferential stopper 131 on the current winding fixing seat and the fixed vertical plate 1202 of the previous winding fixing seat.

[0141] Referring to Figure 6, when the clamping member 410 releases the winding on the winding tray 110 and the winding fixing seat 121, the cylinder 420 drives the two clamping blocks 411 to move closer, that is, the close contact between the supporting member 410 and the inner side of the coil is released. At this time, the Z-direction moving member 433 of the clamping arm 430 drives the supporting member 410 to move upward, thereby releasing the winding 200.

[0142] Afterwards, the supporting member 410 and the winding bracket 100 are reset to proceed with winding the next coil 210 of the winding 200 .

[0143] 3 , in step 20), the bridge wire intermediate body 221 is reserved on top of the wound coil 210 , and in step 10), the coil 210 is bent and formed above the completed bridge wire intermediate body 221 .

[0144] In step 20), the wound coil 210 and the bridge wire intermediate body 221 are supported by the winding bracket 100. Referring to FIG3 , taking the coil 210 on the winding tray 110 as an example, the bridge wire intermediate body 221 connected to the bottom of the coil 210 is directly supported by the winding tray 110.

[0145] In step 30), the plurality of coils 210 are staggered in the vertical and horizontal directions in a stepped manner. The coils 210 of the winding 200 are arranged at intervals along the circumferential direction, and the horizontal height decreases in a step-like manner. Furthermore, in step 40), the bridge wire intermediate body 221 can be deformed to make the end faces of the plurality of coils flush. At this time, the bridge wire 220 is arranged at an angle, that is, it is respectively connected to the upper and lower ends of the two adjacent coils 210. Depending on the winding direction, the bridge wire 220 can be located radially inside or outside the coil 210.

[0146] The winding method further includes: 5) a step of reserving an outlet terminal intermediate body, and in step 10), the coil 210 is wound on the outlet terminal intermediate body or the upper end of the bridge wire intermediate body 221.
