Description

Technical Field

[0001] The present invention relates to the technical field of motor production, and particularly to a layering mechanism for stator wires. Background Art

[0002] The development of electric vehicles has placed increasingly high demands on the performance of drive motors. Due to its high slot fill factor and high performance characteristics, the flat wire motor has become the mainstream of current development. The wire in the stator slot of the flat wire motor is an enameled flat copper wire, and an insertion type wire embedding process is adopted. An insulating paper is provided between the stator slot and the wire. As the slot fill factor becomes higher and the number of copper wire layers increases, the insulating paper has evolved from the traditional "O" type to the "S" type. Compared with the traditional "O" insulating paper, the "S" type insulating paper has an additional partition in the middle. Therefore, the wire insertion difficulty of the "S" type insulating paper is higher, and problems such as copper wire layering errors and damage to the partition insulating paper often occur during wire insertion.

[0003] Therefore, there is an urgent need for a layering mechanism for stator wires to solve the above problems. Summary of the Invention

[0024] The beneficial effects of the present invention are as follows:

[0025] The layering mechanism of the stator conductor proposed in the present invention is suitable for the layering of the conductors of the stator. A plurality of groups of conductors are arranged at circumferential intervals on the stator. The layering mechanism of the stator conductor includes an inner support structure, a tooth guard structure and a branching structure. The inner support structure can be inserted into the first layer of conductors. The inner support structure includes a first inner support and a second inner support arranged coaxially. The tooth guard structure includes a driving assembly and a tooth guard assembly. The driving assembly is used to drive the tooth guard assembly to move radially along the stator. Among them, the tooth guard assembly includes a plurality of first tooth guards, which are arranged to form a first circular ring and can be moved to a first predetermined position radially along the stator, so that the upper end of the first layer of conductors and the upper end of the second layer of conductors are both clamped between the first tooth guard and the first inner support, and the first tooth guard can be used to clamp and fix the corolla end of the stator. The tooth guard assembly also includes a plurality of second tooth guards, which are arranged to form a second circular ring and can be moved radially along the stator. The second guard teeth can first move to the middle predetermined position along the radial direction of the second annular ring, that is, the radial direction of the stator, and cooperate with the second inner support to gather the wires, and then the guard teeth structure moves downward to approach the branching structure, so that the lower end of the wire can be inserted into the branching disk. At this time, the second guard teeth continue to move to the second predetermined position along the radial direction of the stator, so that the lower end of the first layer of wires is clamped between the second guard teeth and the second inner support, that is, the lower end of the first layer of wires is clamped by the second guard teeth, so that the wires are divided into the first layer of wires and other wires except the first layer of wires, and these other wires are the second layer of wires. When the first layer of wires has been clamped between the second guard teeth and the second inner support, the branching structure can be used to separate the first layer of wires and the second layer of wires. Because the first layer of wires has been clamped, the boundary between the first layer of wires and the second layer of wires is clearer, and it is easier to separate the first layer of wires from the second layer of wires. The tooth guard assembly also includes a plurality of third tooth guards, which are arranged to form a third ring and can be moved to a third predetermined position along the radial direction of the stator to clamp the lower end of the second layer of wires. At this point, the first layer of wires and the second layer of wires have been separated, and their lower ends are clamped and fixed respectively to facilitate the subsequent insertion of the first layer of wires and the second layer of wires into the wire embedding grooves of the stator. The layering mechanism of the stator wire can automatically divide each group of wires into the first layer of wires and the second layer of wires in the radial direction of the stator to achieve the S-shaped layering of the stator, that is, before the wires are inserted into the "S"-shaped insulating paper, a small gap is pre-separated in the middle of the multi-layer wires to avoid the partition paper in the middle of the "S"-shaped insulating paper to ensure smooth insertion of the wires and improve production efficiency.

[0052] To make the technical problems solved by the present invention, the technical solutions adopted and the achieved technical effects clearer, the technical solutions of the present invention will be further described below with reference to the drawings and through specific implementation manners. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the drawings rather than all of them.

[0053] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0054] In the present invention, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or simply means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under", and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or simply means that the horizontal height of the first feature is lower than that of the second feature.

[0055] In the description of this embodiment, the orientation or positional relationships such as "upper", "lower", "left", "right", etc. are based on the orientation or positional relationships shown in the drawings. They are only for the convenience of description and simplifying the operations, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0056] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific embodiments.

[0057] As Figures 1 to 15 shown, this embodiment provides a layering mechanism for stator wires, which is applicable to the layering of the wires of the stator. A plurality of groups of wires are circumferentially spaced on the stator. The layering mechanism of the stator wires can automatically divide each group of wires into a first layer of wires 1001 and a second layer of wires 1002 in the radial direction of the stator. The first layer of wires 1001 is located inside the second layer of wires 1002. That is, the layering mechanism of the stator wires can create a small gap in advance between the multi-layer wires before inserting the "S"-shaped insulating paper to achieve the S-shaped layering of the stator, avoid the partition paper in the middle of the "S"-shaped insulating paper, ensure the smooth insertion of the wires, and improve the production efficiency of the motor.

[0058] Optionally, the layering mechanism of the stator wires includes an inner support structure, a tooth protection structure, and a wire splitting structure 9. The inner support structure can be inserted into the first layer of wires 1001. The inner support structure includes a first inner support 7 and a second inner support 8 arranged coaxially. The tooth protection structure includes a driving component and a tooth protection component. The driving component is used to drive the tooth protection component to move along the radial direction of the stator. Among them, the tooth protection component includes a plurality of first teeth 11. The plurality of first teeth 11 surround and form a first ring. The plurality of first teeth 11 can move along the radial direction of the first ring, that is, the radial direction of the stator, to a first predetermined position, so that the upper ends of the first layer of wires 1001 and the second layer of wires 1002 are both clamped between the first teeth 11 and the first inner support 7, and thus the first teeth 11 can be used to clamp and fix the corolla end of the stator.

[0059] The tooth guard assembly also includes a plurality of second tooth guards 21, which are arranged to form a second circular ring, and the plurality of second tooth guards 21 can move along the radial direction of the second circular ring, that is, the radial direction of the stator. The second tooth guards 21 can first move along the radial direction of the stator to a predetermined middle position, and cooperate with the second inner support 8 to gather the wires, and then the tooth guard structure moves downward to approach the branching structure 9, so that the lower end of the wire can be inserted into the branching disk 91, and then the second tooth guard 21 continues to move along the radial direction of the stator to a second predetermined position, so that the lower end of the first layer of wires 1001 is clamped between the second tooth guard 21 and the second inner support 8, that is, the second tooth guard 21 is used to clamp the lower end of the first layer of wires 1001, so that the wires are divided into the first layer of wires 1001 and other wires except the first layer of wires 1001, and these other wires are the second layer of wires 1002. When the lower end of the first layer of wire 1001 has been clamped between the second tooth guard 21 and the second inner support 8, the first layer of wire 1001 and the second layer of wire 1002 can be separated by the wire separation structure 9. Since the lower end of the first layer of wire 1001 has been clamped, the boundary between the first layer of wire 1001 and the second layer of wire 1002 is clearer, and it is easier to separate the first layer of wire 1001 and the second layer of wire 1002.

[0060] The tooth guard assembly also includes a plurality of third tooth guards 31, which are arranged to form a third circular ring. The plurality of third tooth guards 31 can be moved to a third predetermined position along the radial direction of the third circular ring, i.e., the radial direction of the stator, to clamp the lower end of the second layer of wire 1002. At this point, the first layer of wire 1001 and the second layer of wire 1002 have been separated, and their lower ends are respectively clamped and fixed to facilitate the subsequent insertion of the first layer of wire 1001 and the second layer of wire 1002 into the wire embedding groove of the stator.

[0061] The stator is provided with multiple groups of wires at intervals in the circumferential direction, and each group of wires includes multiple wires arranged in sequence along the radial direction of the stator. Since the size of each wire is basically the same and the cross-section is rectangular, the interval between two adjacent groups of wires is a trapezoid, and the short side of the trapezoid is located on the side close to the stator, and the long side of the trapezoid is located on the side away from the stator, that is, the first trapezoidal space between the first layer of wires 1001 of the two adjacent groups of wires is smaller than the second trapezoidal space between the second layer of wires 1002 of the two adjacent groups of wires. In specific implementation, the second guard tooth 21 moves along the radial direction of the stator and first inserts into the gap between the second layer of wires 1002 of the two adjacent groups of wires, and then inserts into the gap between the first layer of wires 1001 of the two groups of wires until it abuts against the second inner support 8, and the third guard tooth 31 is only inserted into the gap between the second layer of wires 1002 of the two adjacent groups of wires, that is, in the radial direction of the stator, the length of the third guard tooth 31 is smaller than the length of the second guard tooth 21.

[0062] Alternatively, if Figure 4 and Figure 5As shown, the first side edge of the first tooth segment 211 of the second tooth guard 21 which is relatively arranged in the radial direction perpendicular to the stator is a beveled side, so that the first tooth segment 211 forms a first wedge-shaped structure, and the first wedge-shaped structure is not completely adapted to the first trapezoidal space, but only the position of the first wedge-shaped structure corresponding to the first predetermined conductor is matched with the first trapezoidal space, so as to realize the clamping of the first predetermined conductor by the first tooth segment 211 in the radial direction perpendicular to the stator, and the first predetermined conductor is the one of the first layer conductors 1001 that is closest to the second layer conductor 1002.

[0063] The second tooth guard 21 also has a second tooth segment 212, which is connected to the side of the first tooth segment 211 away from the second inner support 8. The second tooth segment 212 is provided with an avoidance groove on a second side edge arranged radially opposite to the stator, and the avoidance groove is used to avoid the second layer of wires 1002, that is, to prevent the second tooth segment 212 from abutting against the second layer of wires 1002.

[0064] Alternatively, if Figure 4 and Figure 6 As shown, the third side edge of the third tooth segment 311 of the third tooth guard 31 which is relatively arranged in the radial direction perpendicular to the stator is a beveled side, so that the third tooth segment 311 forms a second wedge-shaped structure, and the second wedge-shaped structure is not completely adapted to the second trapezoidal space, but only the position of the second wedge-shaped structure corresponding to the second predetermined conductor is matched with the second trapezoidal space, so as to realize the clamping of the second predetermined conductor by the third tooth segment 311 in the radial direction perpendicular to the stator, and the second predetermined conductor is a conductor in the second layer of conductors 1002 which is closest to the first layer of conductors 1001.

[0065] The third tooth guard 31 also includes a connecting section 312, which is connected to the side of the third tooth segment 311 away from the stator, and a step surface is formed at the connection between the connecting section 312 and the tooth root of the third tooth segment 311. When the third tooth guard 31 is inserted between two adjacent groups of wires, a wire in the second layer of wires 1002 that is farthest from the first layer of wires 1001 abuts against the step surface, thereby achieving the clamping of the second layer of wires 1002 by the third tooth guard 31.

[0066] Furthermore, if Figure 3 As shown, the outer circumference of the first inner support 7 is provided with a first annular groove 71, and when the first guard tooth 11 moves along the radial direction of the first circular ring, the first guard tooth 11 will be inserted into the first annular groove 71 to press the first layer of wire 1001 against the outer circumference of the first inner support 7. The provision of the first annular groove 71 can increase the matching space between the first guard tooth 11 and the first inner support 7, so as to reduce the size of the outer circumference of the first guard tooth 11 and the first inner support 7 in the radial direction of the stator, and the wire can be pressed and fixed from both sides of the wire in the radial direction of the stator.

[0067] Alternatively, if Figure 4As shown, a second annular groove 81 is provided on the outer peripheral surface of the second inner support 8. When the second tooth guard 21 moves radially along the second ring, the second tooth guard 21 will be inserted into the second annular groove 81 to press the first-layer wire 1001 against the outer peripheral surface of the second inner support 8, that is, the wire closest to the second inner support 8 in the first-layer wire 1001 abuts against the outer peripheral surface of the second inner support 8, and the multiple wires included in the first-layer wire 1001 are successively pressed against each other in the radial direction of the stator. Combined with the fixation of the first predetermined wire by the first tooth insertion section 211, the first-layer wire 1001 is pressed and fixed from both sides of the first-layer wire 1001.

[0068] Optionally, the driving assembly includes a fixed disk and a rotating disk arranged coaxially. A plurality of sliding grooves are arranged at intervals along the circumferential direction of the stator on the fixed disk. The sliding grooves extend in the radial direction of the stator and penetrate the fixed disk toward one end of the stator. A plurality of arc-shaped wire grooves are arranged at intervals along the circumferential direction of the stator on the rotating disk. The tooth guard assembly includes a body part and a driving part. The driving part is arranged on the body part. The body part is arranged in the sliding groove, and the driving part is arranged in the arc-shaped wire groove. The rotating disk rotates relative to the fixed disk to move the body part along the extending direction of the sliding groove.

[0069] In this embodiment, the tooth guard assembly includes a first tooth guard assembly 1, a second tooth guard assembly 2, and a third tooth guard assembly 3. The driving assembly includes a first driving assembly 4, a second driving assembly 5, and a third driving assembly 6. The first driving assembly 4 drives the first tooth guard assembly 1 to move radially along the stator, the second driving assembly 5 drives the second tooth guard assembly 2 to move radially along the stator, and the third driving assembly 6 drives the third tooth guard assembly 3 to move radially along the stator. In addition, the body part of the first tooth guard 11 is the first tooth guard body, and the driving part of the first tooth guard 11 is the first rotating shaft. The body part of the second tooth guard 21 is the second tooth guard body, and the driving part of the second tooth guard 21 is the second rotating shaft. The body part of the third tooth guard 31 is the third tooth guard body, and the driving part of the third tooth guard 31 is the third rotating shaft.

[0070] Specifically, the first driving assembly 4 includes a first rotating disk and a first fixed disk arranged coaxially. A plurality of first sliding grooves are provided on the first fixed disk, and the plurality of first sliding grooves are arranged at intervals along the circumferential direction of the first fixed disk. One first tooth guard 11 is correspondingly arranged in one first sliding groove and encloses to form a first ring. The first rotating disk is covered on the first fixed disk, and a first arc-shaped wire groove is provided on the first rotating disk. This enables the first tooth guard body to be located in the first sliding groove, while the first rotating shaft extends into the first arc-shaped wire groove. When the first rotating disk rotates, the first tooth guard body is restricted by the first sliding groove distributed along the radial direction of the stator and will not rotate around the axial direction of the stator with the first rotating disk. However, the first rotating shaft driven by the first rotating disk will drive the first tooth guard body to slide along the extending direction of the first sliding groove. The first rotating disk is an annular disk and can rotate relative to the first fixed disk. The first fixed disk is an annular disk and can be sleeved on the outer periphery of the stator, and one end of the first sliding groove facing the stator penetrates through the first fixed disk, so that the first tooth guard body can slide in the first sliding groove and can extend out of the first sliding groove to be inserted between two adjacent groups of wires.

[0071] The second driving assembly 5 includes a second rotating disk and a second fixed disk arranged coaxially. A plurality of second sliding grooves are provided on the second fixed disk, and the plurality of second sliding grooves are arranged at intervals along the circumferential direction of the second fixed disk. One second tooth guard 21 is correspondingly arranged in one second sliding groove and encloses to form a second ring. The second rotating disk is covered on the second fixed disk, and a second arc-shaped wire groove is provided on the second rotating disk. This enables the second tooth guard body to be located in the second sliding groove, while the second rotating shaft extends into the second arc-shaped wire groove. When the second rotating disk rotates, the second tooth guard body is restricted by the second sliding groove distributed along the radial direction of the stator and will not rotate around the axial direction of the stator with the second rotating disk. However, the second rotating shaft driven by the second rotating disk will drive the second tooth guard body to slide along the extending direction of the second sliding groove. The second rotating disk is an annular disk and can rotate relative to the second fixed disk. The second fixed disk is an annular disk and can be sleeved on the outer periphery of the stator, and one end of the second sliding groove facing the stator penetrates through the second fixed disk, so that the second tooth guard body can slide in the second sliding groove and can extend out of the second sliding groove to be inserted between two adjacent groups of wires.

[0072] The third driving component 6 includes a third rotating disk and a third fixed disk arranged coaxially. A plurality of third sliding grooves are provided on the third fixed disk, and the plurality of third sliding grooves are arranged at intervals along the circumferential direction of the third fixed disk. One third tooth guard 31 is correspondingly arranged in one third sliding groove and encloses to form a third circular ring. The third rotating disk is covered on the third fixed disk, and a third arc wire groove is provided on the third rotating disk. This enables the third tooth guard body to be located in the third sliding groove, while the third rotating shaft extends into the third arc wire groove. When the third rotating disk rotates, the third tooth guard body is restricted by the third sliding groove distributed along the radial direction of the stator and will not rotate around the axial direction of the stator with the third rotating disk.
