Description

Technical Field

[0001] The invention relates to the technical field of new energy motors, and in particular to a wire arranging device for a motor stator before the motor stator is wire-embedded. Background Art

[0002] The rapid growth of the new energy vehicle market has provided a strong impetus for the development of new energy motor technology. Consumers' demands for range, performance, comfort, etc. continue to drive innovation in motor technology.

[0003] In order to improve the production efficiency of new energy motors, motor manufacturers use automated production to replace manual labor. In the manufacturing process of new energy motor stators, embedding the coil into the stator slot is a crucial step, which is directly related to the performance and efficiency of the motor. In the traditional process, the coil needs to be inserted into the gap between the guide bars before it is embedded in the stator slot. Although mechanized equipment has been introduced to insert the coil, in actual operation, the copper wire of the coil is still prone to irregular sorting problems such as bending and overlapping. This not only greatly reduces the effect of inserting the coil into the guide bar, but also buries hidden dangers in the subsequent automatic wire embedding process, which can easily lead to serious problems such as coil jamming, copper wire deformation and even breakage, which directly affects production efficiency and product quality. In order to solve this problem, manual wire management is currently widely used, which undoubtedly greatly increases production costs, and also makes it difficult to truly realize the fully automated production of motor stator wire embedding.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0034] In this application, if Figure 1 , Figure 2 The structure diagram of the motor stator 100 is shown. The motor stator 100 is cylindrical and has a stator through hole 120 in the center. A plurality of stator slots 110 are arranged on the inner wall of the stator through hole 120 of the motor stator 100. Here, the direction parallel to the symmetric central axis of the motor stator 100 is defined as the axial direction, and the direction the same as the diameter direction of the motor stator 100 is defined as the radial direction. The stator slot 110 penetrates the motor stator 100 along the axial direction of the motor stator 100, and the stator slot 110 has a stator notch 130 on the inner wall of the motor stator 100 along the radial direction.

[0035] In the present application, when the coil 200 is embedded in the stator slot 110 of the motor stator 100, it is necessary to ensure that the copper wires of the coil 200 are neatly arranged so that the copper wires will not be bent, overlapped or damaged during the wire embedding operation; the coil 200 contains multiple copper wires; therefore, it is necessary to perform an operation to organize the copper wires of the coil 200. The present application mainly provides an operation to organize the disordered copper wires of the coil 200 before embedding the motor stator 100, and provides a wire management device for a motor stator.

[0036] like Figure 3 The wire management device shown is arranged on one side of a plurality of conductive bars 300, and the plurality of conductive bars 300 are arranged successively one by one, and a first gap for passing the coil 200 is formed between adjacent conductive bars 300. The main purpose of the conductive bars 300 in the subsequent wire embedding process is to separate the coil 200 and align it with the stator slot 110 of the motor stator 100 through the first gap.

[0037] Regarding the arrangement of the conductive bars 300, it can be set according to the shape of the motor stator 100. In the present application, the motor stator 100 is circular, so a plurality of conductive bars 300 are arranged in a running array; at the same time, according to the stator slots 110 of the motor stator 100 that need to be embedded with wires, the conductive bars 300 can be of two types according to the width of the conductive bars 300, namely, a plurality of first conductive bars 300 and a plurality of second conductive bars 300, wherein the width of the first conductive bar 300 is greater than the width of the second conductive bar 300, and the first conductive bar 300 and the second conductive bar 300 are arranged at intervals, for example, the first conductive bar 300, the second conductive bar 300, the first conductor, the second conductor... are arranged in sequence.

[0038] In order to ensure that the coil 200 can be smoothly and orderly embedded in the first gap between the conductive bars 300, the width of the first gap between adjacent conductive bars 300 is designed to be larger than the diameter of a single copper wire of the coil 200, but smaller than the diameter of two copper wires of the coil 200; such a design is intended to allow a single copper wire to easily enter the gap, while preventing two copper wires from overlapping in the same gap, thereby achieving the purpose of sorting and arranging. Furthermore, the width of the first gap is precisely set to be larger than the diameter of a single copper wire and smaller than 1.5 times the diameter of the copper wire, to ensure the best embedding effect and coil 200 sorting.

[0039] like Figure 3 - Figure 7 The present application provides a wire management device for a motor stator, comprising:

[0040] The wire management mechanism 10 is arranged on one side of the guide bar 300. The wire management mechanism 10 includes a bracket 11 and a rotating member 12 arranged on the bracket 11. As the rotating member 12 rotates, the first end of the rotating member 12 moves toward or away from the guide bar 300.

[0041] A driving mechanism, used for driving the rotating member 12 to rotate;

[0042] The coil 200 passes through the first gap and is located on the side of the first end of the rotating member 12 away from the guide bar 300. The driving mechanism drives the rotating member 12 to rotate, and the first end of the rotating member 12 moves away from the guide bar 300 and pulls the coil 200 to move synchronously so that the coil 200 is arranged in sequence.

[0043] By setting up a rotating member 12 and driving it by a driving mechanism, the first end of the rotating member 12 will pull the coil 200 away from the conductive bar 300, thereby realizing the alignment and arrangement of the copper wires inside the coil 200, effectively solving the problem of irregular arrangement of the copper wires of the coil 200 in the traditional process, and significantly reducing the occurrence of serious problems such as the coil 200 getting stuck, the copper wire deforming or even breaking during the automatic wire embedding process.

[0044] Regarding the cable management mechanism 10, Figure 8 As shown, a rotating seat 15 is provided on the bracket 11, and the rotating member 12 is provided on the rotating seat 15 and can rotate around the rotating shaft 16 on the rotating seat 15. The rotating member 12 includes a first end and a second end, wherein the first end is used to pull the coil 200, and the second end is driven by a driving mechanism. The rotating shaft 16 is provided between the first end and the second end, and the second end is driven by the driving mechanism to rotate around the rotating shaft 16. Using the lever principle, the first end will also rotate around the rotating shaft 16 accordingly, so that the first end can be close to or away from the guide bar 300 as needed, so as to pull and organize the coil 200.

[0045] like Figure 5 and Figure 7The rotating member 12 shown includes a wire management portion 121 and a driving portion 122, wherein one end of the wire management portion 121 is fixedly connected to the driving portion 122, and the other end of the wire management portion 121 is the first end of the rotating member 12, and the opposite end of the driving portion 122 away from the wire management portion 121 is the second end of the rotating member 12. The center of rotation can be set at different positions as needed, and can be set at the connection between the wire management portion 121 and the driving portion 122, or can be designed on the wire management portion 121 or the driving portion 122. In the present application, the center of rotation is designed on the driving portion 122, and it is ensured that the distance from the center of rotation to the first end of the rotating member 12 is greater than the distance from the center of rotation to the second end of the rotating member 12. When the second end of the rotating member 12 is driven to swing in a small range, due to the effect of the lever principle, the first end of the rotating member 12 will swing in a large range, which not only greatly improves the range of motion of the rotating member 12, but also enables the rotating member 12 to complete tasks more flexibly and efficiently in application.

[0046] Among them, Figure 8 The wire-arranging portion 121 shown includes a first wire-arranging plate 1211 and a second wire-arranging plate 1212 arranged side by side, a second slit 13 for the coil 200 to pass through is arranged between the first wire-arranging plate 1211 and the second wire-arranging plate 1212, an opening is arranged at a position of the second slit 13 near the first end of the rotating member 12, and the opening allows the coil 200 to smoothly enter the second slit 13; the width of the second slit 13 is set to be between one copper wire diameter and two copper wire diameters, ensuring that sufficient space is provided for a single copper wire to pass through , and will not let two copper wires pass through at the same time; in order for the copper wire to smoothly enter the second gap 13 from the first gap, the width of the second gap 13 is slightly increased, slightly wider than the first gap, and the two are kept aligned, ensuring that the coil 200 can continue to pass through the second gap 13 without hindrance after passing through the first gap; the second gap 13 provides a smooth channel for the copper wire, reducing the friction and disorder between the copper wires, thereby ensuring the structural stability while significantly improving the fluency and efficiency of the entire coil 200 sorting process.

[0047] The first wiring board 1211 is fixedly connected to the driving part 122, and a wiring pad 14 is arranged between the first wiring board 1211 and the second wiring board 1212. According to the diameter of the copper wire of the coil 200 in the actual production process, the thickness of the wire is adjusted to adjust the width of the second gap 13; the second wiring board 1212 and the wiring pad 14 can be designed as a split structure, and only the wiring pad 14 of different thickness needs to be replaced during adjustment; or, the wiring pad 14 and the first wiring board 1211 are designed as an integrated structure. The purpose of adjustment is achieved by replacing the integrated first wire management plate 1211 and the wire management pad 14; or, the wire management pad 14 is designed as an integral part with the second wire management plate 1212, and the purpose of adjustment is achieved by replacing the integrated second wire management plate 1212 and the wire management pad 14; or, the first wire management plate 1211, the second wire management plate 1212 and the wire management pad 14 are designed as an integral part, and the purpose of adjustment is achieved by replacing the integrated first wire management plate 1211, the second wire management plate 1212 and the wire management pad 14.

[0048] The first wire-arranging plate 1211 and the second wire-arranging plate 1212 in the wire-arranging part 121 are similar in appearance, and both include a wire-arranging segment 1213 that can be parallel to the guide bar 300, a first fixed segment 1214 fixedly connected to the driving part 122, and a connecting segment 1215 for connecting the wire-arranging segment 1213 and the first fixed segment 1214. The connecting segment 1215 extends from the end of the wire-arranging segment 1213 to the side away from the guide bar 300 and is connected to the first fixed segment 1214. The wire-arranging segment 1213, the connecting segment 1215 and the first fixed segment 1214 are integrally formed; the connecting segment 1215 has a certain slope so that the wire-arranging segment 1213 can be closer to the guide bar 300, and the setting of the connecting segment 1215 and the first fixed segment 1214 forms a clearance space, which can be used for the setting of the swivel seat 15. The wire-arranging part 121 not only realizes the arrangement and guidance of the coil 200, but also takes into account the compactness and beauty of the structure.

[0049] The first end of the first wiring board 1211 (the first end here is the first end of the rotating member 12) includes four side surfaces, namely a first side surface, a second side surface, a third side surface and a fourth side surface. The first side surface and the third side surface are arranged opposite to each other and along the movement direction of the first wiring board 1211. The first side surface is a side close to the second slit 13, and the third side surface is a side away from the second slit 13; the second side surface and the fourth side surface are arranged opposite to each other and perpendicular to the movement direction of the first wiring board 1211. The second side surface is a side close to the guide bar 300, and the fourth side surface is a side away from the guide bar 300; a clearance groove 1216 is arranged on the first side surface of the first wiring board 1211; the The three adjacent sides of the give way groove 1216 are open, the first open side is located in the first side surface, the second open side is located in the fourth side surface, and the third open side is located at the end of the first end of the first wiring board 1211. The give way groove 1216 can effectively avoid the coil 200, so that the coil 200 remains round and avoids unnecessary bending; at the same time, a slope 1217 is set on the fourth side surface of the first wiring board 1211, and the top of the slope 1217 (that is, the end of the first end of the rotating member 12) is close to the guide bar 300, and the bottom end is away from the guide bar 300. The slope 1217 facilitates the entry of the coil 200 and also has a guiding function, which can guide the coil 200 to move along a predetermined path.

[0050] As an embodiment of the present application, Figure 8 The driving portion 122 shown includes a second fixed section 1221 connected to the wire management portion 121 and a driving section 1222 driven by a driving mechanism; in the present application, the second fixed section 1221 of the driving portion 122 overlaps and is fixed to the first fixed section 1214 of the wire management portion 121, and is further directly fixedly connected to the first fixed section 1214 of the first wire management plate 1211, and the fixed connection method may be bolt connection, riveting, welding, etc.; bolt connection is used in the present application to facilitate disassembly and replacement.

[0051] like Figure 3 The driving mechanism shown includes a driving assembly 20 for driving the driving part 122 to rotate and a reset assembly 30 for resetting the driving assembly 20. The driving assembly 20 applies a driving force to the driving part 122 so that the driving part 122 rotates around the rotation center, thereby driving the wire-stripping part 121 to move away from the guide bar 300, pulling and aligning the copper wires of the coil 200. After the arrangement is completed, the driving assembly 20 is reset by the reset assembly 30, so that the rotating member 12 is reset, and the wire-stripping part 121 moves close to the guide bar 300, so as to perform the wire-stripping operation next time.

[0052] The driving assembly 20 can be in various forms, for example, it can be driven directly by a cylinder, a motor, a hydraulic cylinder, etc. However, the present application uses an external power to drive the driving assembly 20 so that the rotating member 12 rotates.

[0053] As an embodiment of the present application, Figure 4 - Figure 7 The driving assembly 20 shown includes a first movable plate 21, a second movable plate 22 and a driving roller 23. A driving cavity is formed between the first movable plate 21 and the second movable plate 22. The driving roller 23 is arranged in the driving cavity. The driving roller 23 can roll in the driving cavity. The driving roller 23 is fixed on the driving part 122 and can rotate on the driving part 122. The driving roller 23 is further fixed on the driving section 1222 of the driving part 122. The distance between the first movable plate 21 and the second sliding plate is slightly larger than the diameter of the driving roller 23. In order to facilitate the control and adjustment of the height of the driving cavity, a supporting pad 24 is arranged between the first movable plate 21 and the second movable plate 22. Adjusting the height of the supporting pad 24 can change the distance between the first movable plate 21 and the second movable plate 22.

[0054] The driving component 20 moves along the axial direction, either forward or reverse. When the driving component 20 moves forward, the first movable plate 21 contacts the driving roller 23 and causes the rotating member 12 to rotate. At this time, the driving roller 23 moves toward the guide bar 300, and the wire management portion 121 of the rotating member 12 moves with the coil 200 toward the direction away from the guide bar 300; when the driving component 20 moves reversely, the second movable plate 22 contacts the driving roller 23 and causes the rotating member 12 to rotate. At this time, the driving roller 23 moves toward the direction away from the guide bar 300, and the wire management portion 121 of the rotating member 12 moves toward the guide bar 300 for reset.

[0055] Since one coil 200 needs to be embedded in two stator slots 110 at the same time when the motor stator 100 is being embedded in the wire, synchronous operation is required during sorting and arranging, so the two rotating parts 12 processing the same coil 200 are regarded as a group, that is, a plurality of rotating parts 12 are grouped in pairs and two adjacent ones are grouped together, and a driving roller 23 is arranged between the driving parts 122 of each group of two rotating parts 12, and further, a driving roller 23 is arranged between the driving sections 1222 in the two driving parts 122, that is, one group of rotating parts 12 corresponds to one driving roller 23, and one driving roller 23 synchronously drives the same group of rotating parts 12, and can synchronously pull the coil 200 to ensure that the coil 200 can smoothly and orderly enter the two stator slots 110 during the subsequent wire embedding process.

[0056] The first movable plate 21 is arranged near the first end of the rotating member 12, that is, the first movable plate 21 is located directly above the second movable plate 22. In actual working process, the driving section 1222 of the driving part 122 may affect the movement range of the first movable plate 21, so a guide groove 211 is opened on the first movable plate 21. The number of the guide grooves 211 is the same as the number of the rotating member 12 and corresponds one to one. When the driving part 122 moves, the guide groove 211 allows the driving section 1222 of the driving part 122 to pass through, which can increase the movement range of the first movable plate 21. At the same time, a driving plate is formed between the two guide grooves 211, and the driving plate is pressed on the driving roller 23 to achieve the driving effect.

[0057] Further, a guide protrusion 1223 is provided on the driving section 1222 of the driving part 122 in the direction of the first movable plate 21. The guide protrusion 1223 is inserted into the guide groove 211. Within the range of motion of the first movable plate 21, the guide protrusion 1223 is always in the guide groove 211, effectively preventing the misalignment between the driving section 1222 and the guide groove 211 during operation; once the driving section 1222 is misaligned with the guide groove 211, the first movable plate 21 is directly pressed against the driving section 1222, which may cause the first movable plate 21 to be stuck, thereby hindering the normal movement of the first movable plate 21. By adding the guide protrusion 1223, it is ensured that the first movable plate 21 can smoothly and accurately complete the required action under the guidance of the cooperation of the guide protrusion 1223 and the guide groove 211.

[0058] As an embodiment of the present application, Figure 3 - Figure 7 The reset assembly 30 shown includes a guide post 31 arranged on the bracket 11, a reset spring 32 sleeved on the guide post 31, and a guide hole penetrating the first movable plate 21 and the second movable plate 22, wherein the guide post 31 can pass through the guide hole and can move along the axial direction of the guide hole, and a guide sleeve 33 cooperating with the guide post 31 can be further arranged in the guide hole; the cooperation between the guide post 31 and the guide sleeve 33 enables the second movable plate 22 to move smoothly along a predetermined path during the movement without deviation or shaking. One end of the reset spring 32 abuts on the second movable plate 22, and the other end abuts on the bracket 11; the first movable plate 21 and the second movable plate 22 are forced to move downward, and the second movable plate 22 compresses the reset spring 32 to store energy; when the first movable plate 21 and the second movable plate 22 complete the movement and are no longer subjected to force, the reset spring 32 releases energy to reset, and the reset spring 32 presses against the second movable plate 22 to restore the second movable plate 22 to the initial position, thereby resetting the rotating member 12. The movement accuracy of the reset assembly 30 is improved, thereby ensuring the stability and reliability of the overall mechanical structure.

[0059] In summary, the wire-managing device of the present application realizes the pulling and sorting of the copper wires of the coil 200 by cooperating with the wire-managing mechanism 10 and the driving mechanism; the wire-managing mechanism 10 realizes a larger range of swinging of the first end of the rotating member 12 through the design of the rotating member 12 by the lever principle; a second gap 13 is formed between the first wire-managing plate 1211 and the second wire-managing plate 1212, and the width of the second gap 13 is limited to ensure that the copper wires can be arranged in an orderly and non-overlapping manner; a clearance groove 1216 and an inclined surface 1217 are provided on the first wire-managing plate 1211 to cooperate with each other, which can effectively protect the shape of the copper wire when pulling it, ensure that the copper wire remains round, and avoid unnecessary bending; by providing a wire-managing pad 14, it can be arranged according to the copper wire. The diameter of the wire adjusts the width of the second gap 13; the driving mechanism can drive the driving roller 23 to move in the driving space when the first movable plate 21 is forced to move downward, thereby driving the rotation of the rotating member 12 through the arrangement of the first movable plate 21, the second movable plate 22 and the driving roller 23; at the same time, when the first movable plate 21 is no longer subjected to force, the reset component 30 resets the first movable plate 21, the second movable plate 22 and the driving roller 23, so that the rotating member 12 is reset to prepare for the next arrangement of the coil 200; the device improves production efficiency, makes the subsequent coil 200 embedded in the motor stator 100 smoother, and also improves product quality, ensuring the stability and reliability of the motor operation.
