Detailed Implementation

[0052] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0053] like Figures 1 to 21 As shown, the winding assembly 100 of this embodiment includes a first assembly 1, a second assembly 2, a third assembly 3, a fourth assembly 4, a first winding pin 306, a second winding pin 307, and a third winding pin 409. The second assembly 2 is movably disposed on the first assembly 1 along a first direction. The third assembly 3 includes a third mounting base 301 and a third movable base 302. The third mounting base 301 is movably disposed on the second assembly 2 along a second direction, and the third movable base 302 is movably disposed on the third mounting base 301 along a third direction. The fourth assembly 4 includes a fourth mounting base 401 and a fourth movable base 402. The fourth mounting base 401 is movably disposed on the third mounting base 301 along a third direction, and the fourth movable base 402 is movably disposed on the fourth mounting base 401 relative to the second assembly 2 along the second direction.

[0054] The first winding needle 306 and the second winding needle 307 are disposed on one of the third moving base 302 and the fourth moving base 402, and the third winding needle 409 is disposed on the other of the third moving base 302 and the fourth moving base 402. The first direction is perpendicular to the second direction, and the third direction is perpendicular to each of the first and second directions.

[0055] To make the technical solution of this application easier to understand, the following description further illustrates the technical solution using the following examples: the first direction is consistent with the front-back direction, the second direction is consistent with the left-right direction, and the third direction is consistent with the up-down direction. The front-back direction, left-right direction, and up-down direction are as follows: Figure 1 , Figure 5 , Figure 9 , Figure 13 and Figure 18 As shown.

[0056] For example, such as Figure 1As shown, the second component 2 is movably mounted on the first component 1 in the front-to-back direction. The third mounting base 301 is movably mounted on the second component 2 in the left-to-right direction, and the third movable base 302 is movably mounted on the third mounting base 301 in the up-down direction. The fourth mounting base 401 is movably mounted on the third mounting base 301 in the up-down direction, and the fourth movable base 402 is movably mounted on the fourth mounting base 401 in the left-to-right direction. The first direction is perpendicular to the second direction, and the third direction is perpendicular to each of the first and second directions.

[0057] When winding the stator using the winding assembly 100 of this embodiment, the first winding needle 306, the second winding needle 307, and the third winding needle 409 simultaneously achieve winding in three stator slots. Specifically, the third mounting base 301 moves vertically relative to the second assembly 2, causing the third movable base 302 to move vertically, which in turn causes the winding needles on the third movable base 302 to move vertically. Furthermore, the third movable base 302 moves horizontally relative to the second assembly 2, causing the winding needles on the third movable base 302 to move horizontally, thus winding the enameled wire onto the corresponding stator slots using the winding needles on the third movable base 302. Additionally, the second assembly 2 moves horizontally relative to the first assembly 1, causing the third mounting base 301 and the third movable base 302 to move horizontally, which in turn causes the winding needles on the third movable base 302 to move horizontally, achieving the arrangement of the enameled wire in the corresponding stator slots.

[0058] Simultaneously, the fourth mounting base 401 moves vertically relative to the second component 2, causing the fourth movable base 402 to move vertically as well. This, in turn, causes the winding pins on the fourth movable base 402 to move vertically. Furthermore, the fourth movable base 402 moves horizontally relative to the second component 2, causing the winding pins on the fourth movable base 402 to move horizontally. This allows the enameled wire to be wound onto the corresponding stator slots via the winding pins on the fourth movable base 402. Additionally, the second component 2 moves horizontally relative to the first component 1, causing the third mounting base 301 to move horizontally. This, in turn, causes the fourth mounting base 401 and the fourth movable base 402 to move horizontally, further causing the winding pins on the fourth movable base 402 to move horizontally, thus achieving the winding of the enameled wire onto the corresponding stator slots.

[0059] Those skilled in the art will understand that when the third movable seat 302 and the fourth movable seat 402 move in opposite directions relative to the second component 2 at the same time—for example, when the third movable seat 302 moves from right to left and the third movable seat 402 moves from left to right—the winding direction of the winding needle on the third movable seat 302 is opposite to the winding direction of the winding needle on the fourth movable seat 402. At this time, forward and reverse winding of adjacent phases can be achieved. For example, as... Figure 1 As shown, the first winding needle 306 and the second winding needle 307 are both disposed on the third moving seat 302, and the third winding needle 409 is disposed on the fourth moving seat 402. When the third moving seat 302 and the fourth moving seat 402 move in opposite directions relative to the second component 2 at the same time, the winding direction of the third winding needle 409 is opposite to that of each of the first winding needle 306 and the second winding needle 307.

[0060] Of course, when the third moving seat 302 and the fourth moving seat 402 move in the same direction relative to the second component 2 at the same time, three-phase winding in the same direction can be achieved, that is, the winding directions of the first winding needle 306, the second winding needle 307 and the third winding needle 409 are the same.

[0061] It should be noted that during the stator winding process, the first winding needle 306, the second winding needle 307, and the third winding needle 409 respectively wind different enameled wires onto different stator slots. The first winding needle 306, the second winding needle 307, and the third winding needle 409 can correspond one-to-one with the three phases of the stator.

[0062] Therefore, the winding assembly 100 of this embodiment of the invention can not only realize the simultaneous winding of multiple needles, but also realize the forward and reverse winding of two adjacent phases.

[0063] Therefore, the winding assembly 100 of the present invention has advantages such as high winding efficiency and the ability to meet the forward and reverse winding requirements of two adjacent phases.

[0064] In some embodiments, the first winding needle 306, the second winding needle 307 and the third winding needle 409 are spaced apart along a second direction, and the third winding needle 409 is located between the first winding needle 306 and the second winding needle 307 in the second direction.

[0065] For example, such as Figure 1 and Figure 4 As shown, the first winding needle 306, the second winding needle 307 and the third winding needle 409 are arranged at intervals in the left and right direction. The first winding needle 306 is located to the left of the third winding needle 409, and the third winding needle 409 is located to the left of the second winding needle 307.

[0066] This allows for better fulfillment of user needs.

[0067] Of course, in other embodiments, the first winding needle, the second winding needle, and the third winding needle can also be arranged in other ways, for example, the third winding needle is located directly above the first winding needle.

[0068] Optionally, the third winding needle 409 is disposed on the fourth movable seat 402. The fourth component 4 also includes a position detection device 411, which is used to detect the relative position of the fourth movable seat 402 and the fourth mounting seat 401 in the second direction, so that the third winding needle 409 and the first winding needle 306 have a preset distance in the second direction.

[0069] It is understandable that, since both the fourth mounting base 401 and the third movable base 302 are mounted on the third mounting base 301, and the third mounting base 301 is movably mounted on the second component 2 along the second direction, the relative positions of the fourth mounting base 401 and the third movable base 302 in the second direction remain unchanged when the third mounting base 301 moves along the second direction. However, since the fourth movable base 402 is movable relative to the second component 2 along the second direction, the relative positions of the fourth movable base 402 and the third movable base 302 in the second direction may change, and consequently, the distance between the third winding needle 409 and the first winding needle 306 in the second direction may change. When the third winding needle 409 and the first winding needle 306 have a preset distance in the second direction, the distance between the third winding needle 409 and the second winding needle 307 in the second direction is also determined. The preset distance can be the distance between the first winding needle 306 and the third winding needle 409 when both are in their initial positions.

[0070] When the winding assembly 100 of this embodiment of the invention is used to wind the stator, the relative positions of the fourth moving seat 402 and the fourth mounting seat 401 in the second direction can be detected by the position detection device 411 first, to ensure that the third winding needle 409 and the first winding needle 306 have a preset distance in the second direction, and then the winding assembly is used to wind the stator.

[0071] Therefore, each time the winding assembly 100 is used to wind the stator, the first winding needle 306, the second winding needle 307, and the third winding needle 409 are all in a fixed initial position, which facilitates the control of the first winding needle 306, the second winding needle 307, and the third winding needle 409, and thus facilitates the winding operation of the stator using the winding assembly 100.

[0072] Optionally, the position detection device 411 is a proximity position sensor.

[0073] The position detection device 411 can be electromagnetic, photoelectric, differential transformer, eddy current, capacitive, reed switch, or Hall effect type, etc. For example, the position detection device 411 includes a sensing element 4111 and a photoelectric switch 4112. The sensing element 4111 is fixed on the fourth movable base 402, and the photoelectric switch 4112 is fixed on the fourth mounting base 401.

[0074] Setting the position detection device 411 as a proximity position sensor is beneficial to improving detection accuracy, which in turn is beneficial to improving the reliability of the winding assembly 100.

[0075] Of course, in other embodiments, the position detection device can also be a contact position sensor. For example, the position detection device can be a limit switch, a two-dimensional matrix position sensor, etc.

[0076] Optionally, the first component 1 includes a first mounting base 101, a first slide rail 1012, and a first slider 1021. The first slide rail 1012 is disposed on the first mounting base 101 and extends along a first direction. The first slider 1021 is movably engaged with the first slide rail 1012 along the first direction. The second component 2 includes a second mounting base 201, a second slide rail 2012, and a second slider 2021. The second mounting base 201 is connected to the first slider 1021. The second slide rail 2012 extends along a second direction. The second slider 2021 is movably engaged with the second slide rail 2012 along the second direction. A third mounting base 301 is connected to the second slider 2021.

[0077] The third component 3 further includes a third slide rail 3013, a third slider 3021, and a fourth slider 3022. The third slide rail 3013 extends along a third direction. Each of the third slider 3021 and the fourth slider 3022 is movably engaged with the third slide rail 3013 along a third direction. A third movable seat 302 is connected to the third slider 3021, and a fourth mounting seat 401 is connected to the fourth slider 3022. The fourth component 4 further includes a fourth slide rail 4012 and a fifth slider 4021. The fourth slide rail 4012 extends along a second direction. The fifth slider 4021 is movably engaged with the fourth slide rail 4012 along a second direction. The fourth movable seat 402 is connected to the fifth slider 4021.

[0078] For example, such as Figure 1 , Figure 5 and Figure 8 As shown, the first slide rail 1012 extends in the front-to-back direction, and the first slider 1021 slidably engages with the first slide rail 1012 in the front-to-back direction. The second mounting base 201 is connected to the first slider 1021. Thus, by utilizing the engagement of the first slider 1021 and the first slide rail 1012, the movement of the second component 2 in the front-to-back direction can be guided. Figure 1 , Figure 9 and Figure 12 As shown, the second slide rail 2012 extends in the left-right direction, and the second slider 2021 is movably engaged with the second slide rail 2012 in the left-right direction. The third mounting base 301 is connected to the second slider 2021. Thus, by utilizing the engagement of the second slider 2021 and the second slide rail 2012, the movement of the third mounting base 301 in the left-right direction can be guided.

[0079] like Figure 1 ,like Figure 13 and Figure 14 As shown, the third slide rail 3013 extends vertically, and the third slider 3021 and the fourth slider 3022 are slidably engaged with the third slide rail 3013 in the vertical direction. The third movable seat 302 is connected to the third slider 3021, and the fourth mounting seat 401 is connected to the fourth slider 3022. Thus, by utilizing the engagement of the third slider 3021 with the third slide rail 3013, the vertical movement of the third movable seat 302 can be guided; similarly, by utilizing the engagement of the fourth slider 3022 with the third slide rail 3013, the vertical movement of the fourth mounting seat 401 can be guided. Figure 1 , Figure 18 and Figure 19 As shown, the fourth slide rail 4012 extends in the left-right direction, and the fifth slider 4021 is slidably engaged with the fourth slide rail 4012 in the left-right direction. The fourth movable seat 402 is connected to the fifth slider 4021. Thus, by utilizing the cooperation between the fifth slider 4021 and the fourth slide rail 4012, the movement of the fourth movable seat 402 in the left-right direction can be guided.

[0080] Therefore, by setting up the above-mentioned slide rails and sliders, it is beneficial for the mounting seats and moving seats that need to be moved to move along the preset path, thereby further improving the reliability of the winding assembly 100.

[0081] Those skilled in the art will understand that the slide rail and slider described above can also be interchanged. For example, a first slider can be provided on a first mounting base and a first slide rail can be provided on a first movable base, and the first slider can be movably engaged with the first slide rail in a first direction.

[0082] Optionally, the first component 1 further includes a first slide rail support plate 1011, which is connected to the first mounting base 101, and a first slide rail 1012 is connected to the first slide rail support plate 1011. For example, the first slide rail support plate 1011 is welded to the upper surface of the first mounting base 101, and the first slide rail 1012 is welded to the upper surface of the first slide rail support plate 1011.

[0083] The second component 2 also includes a second slide rail support plate 2011, which is connected to the second mounting base 201, and a second slide rail 2012 is connected to the second slide rail support plate 2011. For example, the second slide rail support plate 2011 is welded to the upper surface of the second mounting base 201, and the second slide rail 2012 is welded to the upper surface of the second slide rail support plate 2011.

[0084] The fourth component 4 also includes a fourth slide rail support plate 4011, which is connected to the fourth mounting base 401, and a fourth slide rail 4012 is connected to the fourth slide rail support plate 4011. For example, the fourth slide rail support plate 4011 is welded and fixed to the upper surface of the fourth mounting base 401, and the fourth slide rail 4012 is welded and fixed to the upper surface of the fourth slide rail support plate 4011.

[0085] Optionally, multiple first slide rails 1012, second slide rails 2012 and third slide rails 3013 are provided, with multiple first slide rails 1012 spaced apart along the second direction, multiple second slide rails 2012 spaced apart along the first direction, and multiple third slide rails 3013 spaced apart along the second direction.

[0086] For example, such as Figure 5 , Figure 9 , Figure 13 and Figure 18 As shown, there are two of each of the first slide rail 1012, the second slide rail 2012 and the third slide rail 3013. The two first slide rails 1012 are spaced apart in the left-right direction, the two slide rails 2012 are spaced apart in the front-back direction, and the two third slide rails 3013 are spaced apart in the left-right direction.

[0087] Optionally, there are multiple first sliders 1021, second sliders 2021 and third sliders 3021, with at least two first sliders 1021 cooperating with the same first slide rail 1012, at least two second sliders 2021 cooperating with the same second slide rail 2021, and at least two third sliders 3021 cooperating with the same third slide rail 3013.

[0088] For example, such as Figure 5 , Figure 9 , Figure 13 and Figure 18 As shown, four of each of the first slider 1021, the second slider 2021, and the third slider 3021 are provided. Every two first sliders 1021 are engaged with the same first slide rail 1012, every two second sliders 2021 are engaged with the same second slide rail 2012, and every two third sliders 3021 are engaged with the same third slide rail 3013.

[0089] Optionally, the first component 1 further includes a plurality of first limiting blocks 109, which are spaced apart on the first mounting base 101 along a first direction. Each of the plurality of first limiting blocks 109 is used to abut against at least one of the second mounting base 201 and the first slider 1021.

[0090] For example, such as Figures 2 to 8 As shown, two first limiting blocks 109 are provided, with one first limiting block 109 located in front of the other. When the first slider 1021 moves forward to its limit position, the first limiting block 109 located in front abuts against the front end face of the second mounting base 201. When the first slider 1021 moves backward to its limit position, the first limiting block 109 located in the rear abuts against the rear end face of the second mounting base 201. This prevents the first slider 1021, which is connected to the second mounting base 201, from disengaging from the first slide rail 1012.

[0091] Of course, in other embodiments, first limiting blocks can be provided on both sides of the length direction of the first slide rail. When the first slider moves forward to the limit position, the first limiting block located on the front side stops against the front end face of the first slider; when the first slider moves backward to the limit position, the first limiting block located on the rear side stops against the rear end face of the first slider.

[0092] The second component 2 also includes a plurality of second limiting blocks 209, which are spaced apart along a second direction on the second mounting base 201. Each of the plurality of second limiting blocks 209 is used to abut against at least one of the third mounting base 301 and the second slider 2021.

[0093] For example, such as Figures 9 to 12 As shown, two second limiting blocks 209 are provided, with one second limiting block 209 located to the left of the other. When the second slider 2021 moves to its leftmost position, the second limiting block 209 on the left abuts against the left end face of the third mounting base 301. When the second slider 2021 moves to its rightmost position, the second limiting block 209 on the right abuts against the right end face of the third mounting base 301. This prevents the second slider 2021, which is connected to the third mounting base 301, from disengaging from the second slide rail 2012.

[0094] Of course, in other embodiments, second limiting blocks can be provided on both sides of the length direction of the second slide rail. When the second slider moves to the left limit position, the second limiting block on the left side stops at the left end face of the second slider; when the second slider moves to the right limit position, the second limiting block on the right side stops at the right end face of the second slider.

[0095] The third component 3 also includes a plurality of third limiting blocks 309, which are spaced apart on the third mounting base 301 along a third direction. At least one of the plurality of third limiting blocks 309 is used to abut against at least one of the third movable base 302 and the third slider 3021, and at least one of the plurality of third limiting blocks 309 is used to abut against at least one of the fourth mounting base and the fourth slider 3022.

[0096] For example, such as Figure 1 , Figures 13 to 17 As shown, two third limiting blocks 309 are provided, with one third limiting block 309 located above the other. The third slider 3021 is located below the fourth slider 3022. When the third slider 3021 moves downward to its limit position, the lower third limiting block 309 abuts against the lower end face of the third moving seat 302. When the fourth slider 3022 moves upward to its limit position, the upper third limiting block 309 abuts against the upper end face of the fourth mounting seat 401. This prevents the third slider 3021, connected to the third moving seat 302, from disengaging from the third slide rail 3012, and also prevents the fourth slider 3022, connected to the fourth mounting seat 401, from disengaging from the third slide rail 3012.

[0097] Optionally, the third component 3 also includes a slider limiting block 310, which is disposed on the third mounting base 301. The slider limiting block 310 is used to stop the fourth slider 3022.

[0098] For example, such as Figure 13 As shown, the slider limiting block 310 is located above the fourth slider 3022. When the fourth slider 3022 moves upward to its limit position, the slider limiting block 310 stops against the upper end face of the fourth slider 3022, thereby preventing the fourth slider 3022 from disengaging from the third slide rail 3012.

[0099] Therefore, by setting the aforementioned limit block, the slider can be effectively prevented from disengaging from the corresponding slide rail, which helps to further improve the reliability and safety of the winding assembly 100.

[0100] Optionally, the first component 1 further includes a first lead screw 103, a first nut 105, and a first motor 106, with the first lead screw 103 engaging with the first nut 105. The first nut 105 is connected to at least one of the second mounting base 201 and the first slider 1021. The first motor 106 is mounted on the first mounting base 101, and its motor shaft is connected to the first lead screw 103 to drive the lead screw 103 to rotate. The second component 2 further includes a second lead screw 203, a second nut 205, and a second motor 206, with the second lead screw 203 engaging with the second nut 205. The second nut 205 is connected to at least one of the third mounting base 301 and the second slider 2021. The second motor 206 is mounted on the second mounting base 201, and its output shaft is connected to the second lead screw 203 to drive the second lead screw 203 to rotate.

[0101] For example, such as Figures 5 to 12 As shown, the first motor 106 is fixed to the first mounting base 101 via a first motor mounting bracket 107. The first lead screw 103 is fixed to the first mounting base 101 via two first lead screw mounting brackets 104 spaced apart in the front-rear direction. The motor shaft of the first motor 106 is fixedly connected to the first lead screw 103 via a first coupling 108. A first movable seat 102 is sleeved on the first nut 105, and the first movable seat 102 is movably arranged in a first direction and connected to the second mounting base 201. Thus, the rotation of the first motor 106 drives the first lead screw 103 to rotate, thereby moving the second mounting base 201 connected to the first nut 105. The second motor 206 is fixed to the second mounting base 201 via a second motor mounting bracket 207. The second lead screw 203 is fixed to the second mounting base 201 via two second lead screw mounting brackets 204 spaced apart in the left-right direction. The motor shaft of the second motor 206 is fixedly connected to the second lead screw 203 via a second coupling 208. A second movable seat 202 is mounted on the outer sleeve of the second nut 205. The second movable seat 202 is movably disposed along a second direction and is connected to the second mounting seat 201. Thus, the second motor 206 drives the second lead screw 203 to rotate, thereby moving the second mounting seat 201 connected to the second nut 205.

[0102] Therefore, the drive mechanisms used to drive the corresponding moving seats on the first component 1 and the second component 2 adopt a screw and nut mechanism, which has a simple structure and good stability, and is conducive to improving the reliability of the winding assembly 100.

[0103] Optionally, the third slider 3021 and the fourth slider 3022 are spaced apart along a third direction. The third component 3 also includes a driving wheel 311, a driven wheel 312, a third motor 316, and a timing belt 313. Each of the driving wheel 311 and the driven wheel 312 is rotatably mounted on the third mounting base 301, and the driving wheel 311 and the driven wheel 312 are spaced apart along a third direction. The third motor 316 is mounted on the third mounting base 301, and the motor shaft of the third motor 316 is connected to the driving wheel 311 to drive the driving wheel 311 to rotate. The timing belt 313 is wound around each of the driving wheel 311 and the driven wheel 312, and each of the third slider 3021 and the fourth slider 3022 is connected to the timing belt 313.

[0104] For example, such as Figure 1 , Figure 13 and Figure 15 As shown, the third slider 3021 is located below the fourth slider 3022, and the driving wheel 311 is located below the driven wheel 312. The third motor 316 is fixed to the third mounting base 301 via the third motor mounting bracket 30161, and the motor shaft of the third motor 316 is fixedly connected to the rotating shaft of the driving wheel 311. Thus, the third motor 316 can drive the driving wheel 311 to rotate, thereby driving the third slider 3021 and the fourth slider 3022, which are connected to the synchronous belt 313, to move synchronously in the vertical direction.

[0105] This facilitates the synchronous movement of the third slider 3021 and the fourth slider 3022 in the vertical direction.

[0106] Optionally, such as Figure 15 As shown, the third component 3 also includes a timing belt connecting block 314 and a timing belt locking plate 315. The timing belt connecting block 314 is connected to the timing belt 313 through the timing belt locking plate 315, and the timing belt connecting block 314 is connected to the fourth movable seat 402.

[0107] Optionally, such as Figure 15 As shown, the driving wheel 311 is mounted on the third mounting base 301 via a locking block 317. The driven wheel 312 is rotatably mounted on the driven wheel rotation shaft 320 via a rolling bearing 318, and the driven wheel rotation shaft 320 is connected to the third mounting base 301 via a driven wheel support plate 319.

[0108] Optionally, the drive wheel 311 is positioned closer to the second mounting base 201 in the third direction relative to the driven wheel 312.

[0109] For example, such as Figure 15As shown, the second mounting base 201 is located below the third mounting base 301, and the driving wheel 311 is located below the driven wheel 312. At this time, the third motor 316 connected to the driving wheel 311 can be set close to the second mounting base 201, that is, the third motor 316 can be set as low as possible, which helps to reduce the center of gravity height of the winding assembly 100 and improve the stability of the winding assembly 100.

[0110] Optionally, such as Figure 1 and Figure 12 As shown, the third mounting base 301 includes a first mounting portion 3011 and a second mounting portion 3012 connected together. The first mounting portion 3011 is located below the second mounting portion 3012 and is connected to the second slider 2021. The second mounting portion 3012 extends vertically as a whole. The third slide rail 3013, the third slider 3021, the fourth slider 3022, the driving wheel 311, the driven wheel 312, the third motor 316, and the synchronous belt 313 are all mounted on the second mounting portion 3012.

[0111] Optionally, the fourth component 4 further includes a fourth lead screw 403, a fourth nut 405, and a fourth motor 406, with the fourth lead screw 403 cooperating with the fourth nut 405. The fourth nut 405 is connected to the fourth movable seat 402, and the fourth motor 406 is mounted on the fourth mounting seat 401. The motor shaft of the fourth motor 406 is connected to the fourth lead screw 403 to drive the fourth lead screw 403 to rotate.

[0112] For example, such as Figure 18 As shown, the fourth motor 406 is fixed to the fourth mounting base 401 via a fourth motor mounting bracket 407. The fourth lead screw 403 is fixed to the fourth mounting base 401 via two fourth lead screw mounting brackets 404 spaced apart in the left-right direction. The motor shaft of the fourth motor 406 is fixedly connected to the fourth lead screw 403 via a fourth coupling 408. The fourth nut 405 is connected to the fourth movable base 402. Thus, the rotation of the fourth motor 406 drives the fourth lead screw 403 to rotate, thereby moving the fourth movable base 402 connected to the fourth nut 405.

[0113] Therefore, the drive mechanism for moving the movable seat on the fourth component 4 adopts a screw and nut mechanism, which has a simple structure and good stability, and is conducive to improving the reliability of the winding assembly 100.

[0114] Optionally, the third slider 3021 is positioned closer to the second mounting base 201 in the third direction relative to the fourth slider 3022.

[0115] For example, such as Figure 1As shown, the second mounting base 201 is located below the third mounting base 301, and the third slider 3021 is located below the fourth slider 3022. At this time, the fourth lead screw 403, the fourth nut 405, and the fourth motor 406 are all positioned away from the first winding needle 306, the second winding needle 307, and the third winding needle 409. This effectively avoids interference between the fourth lead screw 403, the fourth nut 405, and the fourth motor 406 and the winding needles, thereby facilitating the design and manufacturing of the winding assembly 100 and further improving the reliability of the winding assembly 100.

[0116] Of course, in other embodiments, the fourth mounting base may also be directly mounted on the third movable base.

[0117] Optionally, the third component 3 further includes a first support plate 304 and a second support plate 305, which are spaced apart along a second direction. Each of the first support plate 304 and the second support plate 305 is mounted on the third movable seat 302, a first winding needle 306 is mounted on the first support plate 304, and a second winding needle 307 is mounted on the second support plate 305.

[0118] Optionally, the third component 3 further includes a connecting plate 303, which is disposed on the third movable seat 302, and each of the first support plate 304 and the second support plate 305 is disposed on the connecting plate 303.

[0119] For example, such as Figure 13 and Figure 14 As shown, the first support plate 304 is located to the left of the second support plate 305. Both the first support plate 304 and the second support plate 305 are connected to the connecting plate 303, which is connected to the third movable seat 302. This allows the first winding needle 306 and the second winding needle 307 to be positioned on the third movable seat.

[0120] Therefore, there is a large operating space near the first winding pin 306 and the second winding pin 307, which can effectively prevent other parts of the winding assembly 100 from interfering with the winding pins, thereby helping to further improve the reliability of the winding assembly 100.

[0121] Optionally, both the first support plate 304 and the second support plate 305 have a fixed end and a cantilever end. The fixed ends of the first support plate 304 and the second support plate 305 are connected to the connecting plate 303. The first winding needle 306 is provided on the cantilever end of the first support plate 304, and the second winding needle 307 is provided on the cantilever end of the second support plate 305.

[0122] This further allows for a larger operating space near both the first winding pin 306 and the second winding pin 307, which helps to further improve the reliability of the winding assembly 100.

[0123] Optionally, the fourth component 4 further includes a winding support plate 410, a fifth slide rail 4022, and a sixth slider 4023. The winding support plate 410 has a fixed end and an overhanging end facing each other in a third direction. The fixed end is connected to the fourth movable seat 402, and the overhanging end extends towards the second mounting seat 201. A third winding needle 409 is disposed on the overhanging end. The fifth slide rail 4022 is disposed on the connecting plate 303 and extends in a second direction. The sixth slider 4023 is movably engaged with the fifth slide rail 4022 in the second direction, and the winding support plate 410 is connected to the sixth slider 4023.

[0124] For example, such as Figure 18 As shown, the fixed end of the winding support plate 410 is located above the overhanging end of the winding support plate 410. That is, the lower end of the winding support plate 410 is overhanging, and the third winding pin 409 is located on the lower end of the winding support plate 410. This provides a large operating space in the vicinity of the third winding pin 409, which helps to further improve the reliability of the winding assembly 100.

[0125] Furthermore, the fifth slide rail 4022 extends in the left-right direction, and the sixth slider 4023 is movably coupled to the fifth slide rail 4022 in the left-right direction. The winding support plate 410 is connected to the sixth slider 4023. Thus, the cooperation between the sixth slider 4023 and the fifth slide rail 4022 guides the movement of the winding support plate 410 in the left-right direction, thereby further improving the reliability of the winding assembly 100.

[0126] The winding method of this invention is implemented using the winding assembly described in any of the above embodiments. The winding method includes moving the third moving seat 302 in the opposite direction to the fourth moving seat 402 in the second direction, so that the winding direction of the third winding needle 409 is opposite to the winding direction of the first winding needle 306 and the second winding needle 307.

[0127] The following is for reference. Figures 1 to 21 Description of the winding method according to an embodiment of the present invention:

[0128] The third mounting base 301 moves vertically relative to the second component 2, causing the third movable base 302 to move vertically as well. This, in turn, moves the first winding needle 306 and the second winding needle 307 vertically. The third movable base 302 moves horizontally relative to the second component 2, causing the first winding needle 306 and the second winding needle 307 to move horizontally as well. This allows the enameled wire to be wound onto the corresponding stator slots via the first winding needle 306 and the second winding needle 307. Furthermore, the second component 2 moves horizontally relative to the first component 1, causing the third mounting base 301 and the third movable base 302 to move horizontally as well. This, in turn, moves the first winding needle 306 and the second winding needle 307 horizontally as well, achieving the arrangement of the enameled wire on the corresponding stator slots.

[0129] Simultaneously, the fourth mounting base 401 moves vertically relative to the second component 2, causing the fourth movable base 402 to move vertically, which in turn causes the third winding needle 409 to move vertically. Furthermore, the fourth movable base 402 moves horizontally relative to the second component 2, causing the third winding needle 409 to move horizontally, thus winding the enameled wire onto the corresponding stator slot via the third winding needle 409. Additionally, the second component 2 moves horizontally relative to the first component 1, causing the third mounting base 301 to move horizontally, which in turn causes the fourth mounting base 401 and the fourth movable base 402 to move horizontally, which in turn causes the third winding needle 409 to move horizontally, achieving the routing of the enameled wire onto the corresponding stator slot.

[0130] By controlling the direction and speed of the fourth moving seat 402 relative to the third mounting seat 301 in the left and right directions, and the direction and speed of the third moving seat 302 relative to the third mounting seat 301 in the left and right directions, the third moving seat 302 can be made to move in the opposite direction to the fourth moving seat 402 in the second direction, thereby realizing that the winding direction of the third winding needle 409 is opposite to the winding direction of the first winding needle 306 and the second winding needle 307.

[0131] Therefore, the winding method of the present invention has the advantages of high winding efficiency and the ability to meet the forward and reverse winding requirements of adjacent two phases.

[0132] The winding machine of this invention includes a frame, a positioning component, and a winding component. The positioning component is mounted on the frame and is used to fix the stator. The winding component is the winding component 100 described in any of the above embodiments. The winding component is mounted on the frame and cooperates with the positioning component to wind the stator.
