Description

Technical Field

[0001] The invention relates to the technical field of motor production, and in particular to a stator coil copper wire assembly mechanism based on motor production. Background Art

[0002] Flat wire motor is a motor with smaller overall size. It is used in new energy vehicles due to its good heat dissipation ability and small size.

[0003] Flat wire motors are also called hairpin motors. In the stator coil, the copper wire is assembled in a different way from the winding method. The thicker flat copper wire is fixed by inserting the wire and then welded to form a coil.

[0004] According to patent number CN118611367A, published (announcement) date: 2024-09-06, a new energy stator hairpin wire assembly device is disclosed, including a bracket for supporting the stator, a press-fitting unit for applying pressure to the hairpin wire, and a support unit for inserting into the interval space between two hairpin wires and supporting the curved portion, the support unit including: a mounting plate; a moving disk with a through hole, the moving disk is rotatably arranged on the mounting plate, and a cam groove is provided on the moving disk; a fixed disk with a through hole, the fixed disk cooperates with the moving disk, the fixed disk is fixed to the mounting plate, and a guide groove is provided on the end face of the fixed disk facing the moving disk; a slider, the slider is slidably matched with the guide groove; a transmission component, one end of the transmission component is connected to the slider, and the other end of the transmission component is matched with the cam groove; a driving component that drives the moving disk to rotate, and the driving component is connected to the moving disk. When the hairpin winding is passed through the insulating paper, the present invention can prevent the curved portion of the hairpin wire from causing external turning or damage to the insulating paper.

[0005] In the prior art including the above-mentioned patent, when the flat copper wire is assembled with the stator, an insulating paper sleeve will be pre-pinned on the stator to facilitate the insertion of the flat wire and to insulate the out-of-phase flat wire. Since the friction of the rubber layer on the flat copper wire is greater than the inner wall of the metal stator, a section of the insulating paper sleeve needs to be reserved outside the stator so that it can be moved into the stator during assembly. However, the friction will change due to the offset of the plug-in force of the flat copper wire, which can easily cause one end of the stator to extend too far as the flat copper wire is inserted, affecting the insulation capacity. Summary of the invention

[0006] The purpose of the present invention is to provide a stator coil copper wire assembly mechanism based on motor production, aiming to solve the above problems.

[0007] In order to achieve the above object, the present invention provides the following technical solution: a stator coil copper wire assembly mechanism based on motor production, comprising a stator, an insulating paper sleeve inserted into a coil slot of the stator, and a pre-assembled flat wire group, the pre-assembled flat wire group comprising a glue layer and a metal layer, and further comprising:

[0008] A plurality of auxiliary plug angles, which are driven to be inserted between two insulating paper sleeves;

[0009] A paper fixing assembly, comprising vertical laminating blocks slidably connected to both sides of the auxiliary plug corners;

[0019] Preferably, the first laminating plate and the second laminating plate are provided with rubber protrusions, and the rubber protrusions limit the outward movement of the first laminating plate and the second laminating plate.

[0020] In the above technical scheme, the present invention provides a stator coil copper wire assembly mechanism based on motor production, which has the following beneficial effects: through the paper fixing component, during assembly, multiple auxiliary plug angles are driven close to the stator in which the insulating paper sleeve has been inserted. When assembling, the flat wire group will be inserted along the insulating paper sleeve, from the metal layer to the glue layer.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0036] like Figure 1-11 As shown, a stator coil copper wire assembly mechanism based on motor production includes a stator 3, an insulating paper sleeve 2 inserted into a coil slot 31 of the stator 3, and a pre-assembled flat wire group, wherein the pre-assembled flat wire group includes a glue layer and a metal layer, and further includes:

[0037] A plurality of auxiliary plug angles 1, which are driven to be inserted between two insulating paper sleeves 2;

[0038] The paper fixing assembly 5 comprises vertical fitting blocks 51 slidably connected to both sides of the auxiliary plug corner 1;

[0039] The vertical laminating block 51 moves after the glue layer enters the insulating paper sleeve 2 to push the middle section of the insulating paper sleeve 2 to adhere to the glue layer and form a gap between the insulating paper sleeve 2 and the glue layer.

[0040] Specifically, a second slide groove 12 is provided on the auxiliary plug angle 1, and a sliding portion 52 is provided on the vertical fitting block 51. The sliding portion 52 is slidably connected to the second slide groove 12. When assembling, the pre-assembled flat wire group will be clamped and fixed and moved to insert into the insulating paper sleeve 2. At this time, the metal layer at the head end of the pre-assembled flat wire group is inserted first, and as it continues to move, the glue layer is inserted into the insulating paper sleeve 2. At this time, the vertical fitting block 51 will slide along the horizontal direction of the second slide groove 12 and move toward the insulating paper sleeve 2 to push the middle section of the insulating paper sleeve 2 to fit the glue layer, and form a gap between the insulating paper sleeve 2 and the glue layer (such as Fig.11 As shown), compared with the whole surface bonding, the contact area is smaller, and it is not easy to drive the insulating paper sleeve 2 to move, and the two vertical bonding blocks 51 of the two auxiliary plug corners 1 are bonded to the insulating paper sleeve 2, which can play an auxiliary guiding role and avoid the deviation of the flat copper wire.

[0041] Furthermore, the auxiliary plug angle 1 is connected to the output end of the motor, and the auxiliary plug angle 1 is moved close to the stator 3 by the telescopic motor. The pre-assembled flat wire group is pre-assembled and woven through a mold, which belongs to the prior art and will not be described in detail.

[0042] In the above technical solution, through the paper fixing component 5, during assembly, multiple auxiliary plug angles 1 are driven close to the stator 3 in which the insulating paper sleeve 2 has been inserted. During assembly, the flat wire group will be inserted along the insulating paper sleeve 2, from the metal layer to the glue layer. At this time, the vertical fitting block 51 will move to push against the middle section of the insulating paper sleeve 2, and form a gap between the insulating paper sleeve 2 and the glue layer, thereby reducing the friction area between the insulating paper sleeve 2 and the glue layer, reducing the friction force, and reducing the probability of the insulating paper sleeve 2 being too immersed in the stator 3.

[0043] As an embodiment provided by the present invention, the paper fixing assembly 5 also includes a limiting flap 50 rotatably connected to both sides of the auxiliary plug corner 1, and a stagnation groove 21 corresponding to the limiting flap 50 is provided on the insulating paper sleeve 2. After the insulating paper sleeve 2 slides along the coil groove 31 to a predetermined position, the limiting flap 50 flips over and is stuck in the stagnation groove 21.

[0044] Specifically, a movable groove 13 is provided on the auxiliary plug corner 1, and a rotating shaft 501 is provided on the limiting flap 50, and the rotating shaft 501 is rotatably connected to the movable groove 13. A stagnation groove 21 corresponding to the limiting flap 50 is provided on the insulating paper sleeve 2. When the insulating paper sleeve 2 is supported by the vertical fitting block 51, it will still move slightly. In order to avoid the small probability of excessive deviation of the pre-assembled flat wire group during pre-assembly, causing the insulating paper sleeve 2 to sink into the coil groove 31, after the insulating paper sleeve 2 slides to a predetermined position (the predetermined position is when the insulating paper sleeve 2 moves away from the vertical fitting block 51), the limiting flap 50 will flip and fit the insulating paper sleeve 2. At this time, when the insulating paper sleeve 2 continues to move, the stagnation groove 21 on the insulating paper sleeve 2 is used to limit the position of the insulating paper sleeve 2, thereby avoiding the insulating paper sleeve 2 from sinking into the coil groove 31 due to excessive deviation during pre-assembly.

[0045] When assembling, the pre-assembled flat wire group will be clamped and fixed and moved to insert into the insulating paper sleeve 2. At this time, the metal layer at the head end of the pre-assembled flat wire group will be inserted first, and as it continues to move, the glue layer will be inserted into the insulating paper sleeve 2. At this time, the vertical bonding block 51 will slide along the horizontal direction of the second slide groove 12 and move toward the insulating paper sleeve 2 to push the middle section of the insulating paper sleeve 2 to fit the glue layer and form a gap between the insulating paper sleeve 2 and the glue layer. After the insulating paper sleeve 2 slides to the predetermined position, the limiting flap 50 will flip over and fit the insulating paper sleeve 2. At this time, when the insulating paper sleeve 2 continues to move, it will be in the stagnation groove 21 on the insulating paper sleeve 2 to limit the position of the insulating paper sleeve 2.

[0046] As an embodiment provided by the present invention, a second spring 502 is arranged between the limiting flap 50 and the auxiliary plug angle 1, and a push plate 54 is arranged on the vertical bonding block 51. The vertical bonding block 51 is driven by the bonding adhesive layer to slide along the vertical direction to drive the push plate 54 to push the limiting flap 50 to flip.

[0047] Specifically, a second spring 502 is arranged between the limiting flap 50 and the movable groove 13, and a push plate 54 is arranged on the vertical fitting block 51. The second spring 502 will pull the limiting flap 50 to make the limiting flap 50 flip to a default state (the default state is a state that is not fitted with the insulating paper sleeve 2). When the vertical fitting block 51 will fit the adhesive layer and slide along the vertical direction (the vertical direction is the assembly direction of the flat wire group), the push plate 54 will push the limiting flap 50 to overcome the pulling force of the second spring 502, so that the limiting flap 50 will flip and fit the insulating paper sleeve 2.

[0048] When assembling, the pre-assembled flat wire group will be clamped and fixed and moved to insert into the insulating paper sleeve 2. At this time, the metal layer at the head end of the pre-assembled flat wire group will be inserted first, and as it continues to move, the rubber layer will be inserted into the insulating paper sleeve 2. At this time, the vertical fitting block 51 will slide along the horizontal direction of the second slide groove 12 and move toward the insulating paper sleeve 2 to push the middle section of the insulating paper sleeve 2 to fit the rubber layer, and form a gap between the insulating paper sleeve 2 and the rubber layer. After the insulating paper sleeve 2 slides to a predetermined position, the vertical fitting block 51 will fit the rubber layer and slide in the vertical direction. At this time, the pushing plate 54 will push the limiting flap 50 to overcome the pulling force of the second spring 502, so that the limiting flap 50 will flip and fit the insulating paper sleeve 2. At this time, when the insulating paper sleeve 2 continues to move, it will be in the stagnation groove 21 on the insulating paper sleeve 2 to limit the position of the insulating paper sleeve 2.

[0049] Furthermore, a fitting slide plate 551 is provided on the vertical fitting block 51, and a third spring 552 is provided between the vertical fitting block 51 and the fitting slide plate 551. The third spring 552 pushes the fitting slide plate 551 to slide in contact with the auxiliary plug angle 1 to keep the vertical fitting block 51 sliding horizontally. When the vertical fitting block 51 slides in the horizontal direction, the fitting slide plate 551 is kept in contact with the bottom of the second slide groove 12 by the third spring 552.

[0050] As an embodiment provided by the present invention, it also includes a pre-guide component 4, which includes a group slider 41 slidably connected to the auxiliary plug angle 1, a first spring 423 is arranged between the auxiliary plug angle 1 and the group slider 41, and a rotating guide roller 40 is rotatably connected to the group slider 41, and the two rotating guide rollers 40 are fitted to the pre-assembled flat wire group for guidance.

[0051] Specifically, the group slider 41 is slidably connected to the first slide groove 11 opened on the auxiliary plug corner 1. The auxiliary plug corner 1 is hollow and is provided with a covering top plate 10. A fixed plate 42 is provided in the auxiliary plug corner 1. A first spring 423 is provided between the fixed plate 42 and the group slider 41. The first spring 423 is used to push the group slider 41 to slide along the first slide groove 11 and fit the rotating guide roller 40 on the adjacent auxiliary plug corner 1. During equipment, the metal layer of the pre-assembled flat wire group will squeeze out two mutually fitting rotating guide rollers 40 to guide the pre-assembled flat wire group through the pushing force of the two symmetrical rotating guide rollers 40 and the first spring 423.

[0052] When assembling, the metal layer of the pre-assembled flat wire group will squeeze out the two mutually fitted rotating guide rollers 40, so as to guide the pre-assembled flat wire group through the pushing force of the two symmetrical rotating guide rollers 40 and the first spring 423 and move it into the insulating paper sleeve 2. At this time, the metal layer at the head end of the pre-assembled flat wire group is inserted first, and as it continues to move, the rubber layer is inserted into the insulating paper sleeve 2. At this time, the vertical fitting block 51 will slide along the horizontal direction of the second slide groove 12 and move toward the insulating paper sleeve 2. It moves to push the middle section of the insulating paper sleeve 2 to fit the glue layer, and form a gap between the insulating paper sleeve 2 and the glue layer. After the insulating paper sleeve 2 slides to a predetermined position, the vertical fitting block 51 fits the glue layer and slides in the vertical direction. At this time, the pushing plate 54 pushes the limiting flap 50 to overcome the pulling force of the second spring 502, so that the limiting flap 50 will flip and fit the insulating paper sleeve 2. At this time, when the insulating paper sleeve 2 continues to move, the stagnation groove 21 on the insulating paper sleeve 2 limits the position of the insulating paper sleeve 2.

[0053] As an embodiment provided by the present invention, the rotating guide roller 40 rotates as the adhesive layer passes through, so as to drive the vertical laminating block 51 to move in the horizontal direction to laminat the adhesive layer.

[0054] The group slider 41 is provided with a first transmission belt 43 and a second transmission belt 431 coupled to each other. The first transmission belt 43 is sleeved on the rotating guide roller 40. The second transmission belt 431 is coupled to the tooth plate 53 on the vertical bonding block 51. The rotating guide roller 40 rotates with the rubber layer to drive the tooth plate 53 to move.

[0055] Specifically, a transmission groove 411 for the first transmission belt 43 to move is provided on the group slider 41, a first central axis 421 for carrying the first transmission belt 43 and a second central axis 422 for carrying the second transmission belt 431 are provided on the fixed plate 42, a guide groove 511 is provided on the vertical bonding block 51, and a limiting block 121 corresponding to the guide groove 511 is provided on the second groove 12. When the metal layer passes through the rotating guide roller 40, the rotating guide roller 40 will not rotate significantly due to the small friction force, and when the rubber layer passes through the rotating guide roller 40, the rotating guide roller 40 will rotate due to the increased friction force. The rotating rotating guide roller 40 will drive the first transmission belt 43 and the second transmission belt 431 to rotate, thereby coupling the tooth plate 53 to drive the vertical bonding block 51 to slide horizontally. At this time, after the vertical bonding block 51 slides horizontally to bond the insulating paper sleeve 2, the limiting block 121 will correspond to the guide groove 511 and move along the limiting block 121 when the vertical bonding block 51 moves vertically.

[0056] Furthermore, the force for the vertical bonding block 51 to slide horizontally is transmitted by the friction of the flat wire group and the rubber layer assembled on the rotating guide roller 40, and the rotating guide roller 40 is continuously rotating, so that the vertical bonding block 51 will continue to bond with the insulating paper sleeve 2 when it is not moving vertically.

[0057] When assembling, the metal layer of the pre-assembled flat wire group will squeeze out the two mutually fitted rotating guide rollers 40, so as to guide the pre-assembled flat wire group and move it into the insulating paper sleeve 2 through the pushing force of the two symmetrical rotating guide rollers 40 and the first spring 423. At this time, the metal layer at the head end of the pre-assembled flat wire group is inserted first, and as it continues to move, the rubber layer is inserted into the insulating paper sleeve 2. At this time, the rotating rotating guide roller 40 will drive the first transmission belt 43 and the second transmission belt 431 to rotate, thereby coupling the tooth plate 53 to drive the vertical fitting block 51 to slide in the horizontal direction of the second slide groove 12 and move toward the insulating paper sleeve 2. To push the middle section of the insulating paper sleeve 2 to fit the glue layer, and form a gap between the insulating paper sleeve 2 and the glue layer. At the same time, the limiting block 121 will correspond to the guide groove 511. After the insulating paper sleeve 2 slides to a predetermined position, the vertical fitting block 51 will fit the glue layer and slide in the vertical direction. The limiting block 121 will correspond to the guide groove 511 to achieve vertical sliding. At this time, the pushing plate 54 will push the limiting flap 50 to overcome the pulling force of the second spring 502, so that the limiting flap 50 will flip and fit the insulating paper sleeve 2. At this time, when the insulating paper sleeve 2 continues to move, the stagnation groove 21 on the insulating paper sleeve 2 limits the position of the insulating paper sleeve 2.

[0058] As an embodiment provided by the present invention, it also includes a guide assembly 6, which includes a fitting ring segment arranged on the auxiliary plug angle 1, and the fitting ring segment moves with the plurality of auxiliary plug angles 1 to fit each other to limit the vertical fitting block 51;

[0059] The bonding ring segment includes an elastic arc 61 arranged between two vertical bonding blocks 51 and a first bonding plate 63 and a second bonding plate 631 respectively arranged on both sides of the auxiliary plug angle 1, an elastic bifurcation angle 62 is arranged between the first bonding plate 63 and the second bonding plate 631, and a support is arranged between the elastic bifurcation angle 62 and the elastic arc 61.

[0060] Specifically, the initial angles of the first bonding plate 63 and the second bonding plate 631 are different, so that the first bonding plate 63 and the second bonding plate 631 will be bonded with each other as the auxiliary plug angle 1 moves. The elastic arc 61 is arranged between the two vertical bonding blocks 51 on the same auxiliary plug angle 1. When multiple auxiliary plug angles 1 are driven to approach the insulating paper sleeve 2 in turn, multiple bonding ring segments will bond with each other to form a bonding ring. When the vertical bonding block 51 is driven by the rotating guide roller 40 to move, the elastic arc 61 will expand outward, thereby pulling the elastic bifurcation angle 62 to make the first bonding plate 63 and the second bonding plate 631 retract along the auxiliary plug angle 1 and flip the angle, so that the adjacent first bonding plates 63 and the second bonding plates 631 are fixed to each other, so that when a single flat wire of the flat wire group deviates, a first bonding plate 63 or a second bonding plate 631 that is bonded to each other cannot move when a deviation occurs, so that a small deviation correction can be performed with the help of the push of the elastic arc 61, which is convenient for subsequent wire opening operation.

[0061] The flat wire group is composed of a plurality of flat wires, and after being inserted into the insulating paper sleeve 2 , a wire opening operation needs to be performed to fill the insulating paper sleeve 2 .

[0062] When assembling, the metal layer of the pre-assembled flat wire group will squeeze out the two mutually fitting rotating guide rollers 40, so as to guide and move the pre-assembled flat wire group into the insulating paper sleeve 2 through the pushing force of the two symmetrical rotating guide rollers 40 and the first spring 423. At this time, the metal layer at the head end of the pre-assembled flat wire group is inserted first, and as it continues to move, the rubber layer is inserted into the insulating paper sleeve 2. At this time, the rotating rotating guide roller 40 will drive the first transmission belt 43 and the second transmission belt 431 to rotate, thereby coupling the tooth plate 53 to drive the vertical bonding block 51 to slide in the horizontal direction of the second slide groove 12, and move toward the insulating paper sleeve 2 to push the middle section of the insulating paper sleeve 2 to fit the rubber layer, and form a gap between the insulating paper sleeve 2 and the rubber layer. The elastic arc 61 will expand outward, thereby pulling the elastic bifurcation angle 62 to retract the first bonding plate 63 and the second bonding plate 631 along the auxiliary insertion angle 1, and flip the angle, so that the adjacent first bonding plates 63 and the second bonding plates 631 are fixed to each other, so that when a single flat wire of the flat wire group deviates, a first bonding plate 63 or a second bonding plate 631 that is bonded to each other cannot move when a deviation occurs, so that a small deviation correction is performed with the help of the elastic arc 61. At the same time, the limiting block 12 1 will correspond to the guide groove 511, and when the insulating paper sleeve 2 slides to the predetermined position, the vertical fitting block 51 will fit the glue layer and slide in the vertical direction, and the limiting block 121 will correspond to the guide groove 511 to achieve vertical sliding. At this time, the push plate 54 will push the limiting flap 50 to overcome the pulling force of the second spring 502, so that the limiting flap 50 will flip and fit the insulating paper sleeve 2. At this time, when the insulating paper sleeve 2 continues to move, the stagnation groove 21 on the insulating paper sleeve 2 is inside to limit the position of the insulating paper sleeve 2.

[0063] As the best embodiment provided by the present invention, the first laminating plate 63 and the second laminating plate 631 are provided with rubber protrusions, and the rubber protrusions limit the outward movement of the first laminating plate 63 and the second laminating plate 631.

[0064] Specifically, one side of the rubber protrusion is a copper sheet, and the other side is rubber. The rubber sides of the rubber protrusions on the first bonding plate 63 and the second bonding plate 631 correspond to each other, so that the friction force of the rubber can be used to limit the outward movement of the first bonding plate 63 and the second bonding plate 631, so that when the first bonding plate 63 and the second bonding plate 631 are normally retracted, the copper sheet can be used to reduce friction.

[0065] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
