Description

Technical Field

[0002] The stator is a fixed component in the motor, consisting of three parts: the stator core, the stator winding and the frame. Its main function is to generate a rotating magnetic field. The rotor moves in this rotating magnetic field and generates electromagnetic force through the cutting of magnetic lines of force, thereby realizing mechanical movement or output current.

[0003] In the prior art, a coil needs to be wound on a stator core. In order to ensure the uniformity of the coil winding, a winding device needs to be used to wind the coil.

[0004] However, there are still some problems in the use of the above motor stator winding device: Due to the complex structure of the inner wall of the stator, there are great obstacles to the winding of the coil, and the winding device has high requirements for the tightness of the core wire; when the core wire wound by the winding device becomes loose or the core wire is staggered in multiple layers, the wound coil will become loose to a certain extent, resulting in insufficient contact between the core wires. The too loose winding may be deformed under high-speed rotation, affecting the balance of the motor; and when the core wire is completed, since the core wire has a certain toughness and friction, although the ends of the core wire winding are in a taut state, the middle position of the core wire winding may still be in a loose state, which will cause problems such as loose contact between the core wires, affecting the winding effect.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1-10 As shown, a motor stator winding device, such as Figure 1-3 As shown, it includes a chassis 1 and a first mounting seat 2 for placing the motor stator, and a winding mechanism 3 and a guide mechanism 4 are arranged on the chassis 1; the winding mechanism 3 winds the core wire on the motor stator; the guide mechanism 4 is used to provide guidance when the core wire is wound; the chassis 1 is provided with an adjustment mechanism 5 for tightening the core wire wound on the motor stator; the adjustment mechanism 5 includes: a driving member 51, and the driving member 51 is installed on the chassis 1; it can be understood that the driving member 51 is a prior art, such as Figure 3 The cylinder structure in the embodiment of the present invention comprises a clamping mechanism 52, wherein the clamping mechanism 52 is arranged above the winding position of the motor stator; the clamping mechanism 52 is connected to the driving member 51; the driving member 51 is used to drive the clamping mechanism 52 to move; when the driving member 51 drives the clamping mechanism 52 to contact the core wire wound on the motor stator, the clamping mechanism 52 is used to drive the core wire to move along its winding direction, driving each circle of the core wire with different numbers of circles wound on the motor stator to move synchronously along its winding direction to tighten the core wire.

[0022] It should be noted that in the process of winding the core wire onto the motor stator, when the core wire is wound to a certain number of turns, the driving member 51 drives the clamping mechanism 52 to descend, so that the clamping mechanism 52 contacts the core wire wound on the motor stator, and the core wire is pushed to continue to move along the winding direction of the core wire by the clamping mechanism 52, so as to increase the tightness of the core wire wound on the motor stator. By pushing the core wire by the clamping mechanism 52, each turn of the core wire with different numbers of turns wound on the motor stator can be driven to move synchronously along its winding direction, so that its overall tightness is adjusted, instead of adjusting the tightness by dragging the end of the core wire, to ensure that the force on the core wire wound on the motor stator is relatively uniform.

[0023] like Figure 1-5 and Figure 8 As shown, the clamping mechanism 52 includes a position control mechanism 525, at least one clamping block 521, a plurality of spacer bars 522 and an anti-slip member 523; at least one clamping block 521 is connected to the output end of the driving member 51, the spacer bars 522 are arranged at intervals on the clamping block 521, the distance between adjacent spacer bars 522 is equal to the distance between adjacent core wires wound on the motor stator, and the anti-slip member 523 is arranged between adjacent spacer bars 522; the position control mechanism 525 is used to adjust the distance between the clamping block 521 and the core wire wound on the motor stator on the radial section of the motor stator; the spacer bar 522 includes a mounting bar, a deformation part and a first compression spring; the mounting bar is inserted into the clamping block 521, the first compression spring is arranged between the mounting bar and the clamping block 521, and the deformation part is connected to the mounting bar; when the deformation part is squeezed by the core wire, the deformation part and the mounting bar can be pushed to move into the clamping block 521; when the deformation part is separated from the core wire, the first compression spring is used to drive the mounting bar to automatically reset.

[0024] It should be noted that when the tension of the core wire needs to be adjusted, the position control mechanism 525 pushes the clamping block 521 to approach the core wire wound on the motor stator, so that the clamping mechanism 52 moves to the adjacent position of each circle of the core wire, so that the spacer bar 522 can push the core wire to be arranged regularly, and at the same time, the core wire can be accurately aligned with the anti-slip member 523; when the spacer bar 522 conflicts with the core wire, the pressure between the spacer bar 522 and the core wire increases, which will cause the deformation part to deform and push the core wire to move to both sides, so as to achieve the purpose of adjusting the core wire arrangement position, and as the spacer bar 522 continues to approach the core wire, it will push the first compression spring to be further compressed until the anti-slip member 523 conflicts with the core wire; At this time, the driving member 51 drives the clamping mechanism 52 to descend, so that the spacer bar 522 and the anti-slip member 523 move downward, and the friction between the spacer bar 522, the anti-slip member 523 and the core wire pulls the core wire, so that the core wire continues to move along its winding direction, so as to achieve the purpose of improving the tightness of the core wire wound on the motor stator; that is, due to the arrangement of multiple anti-slip members 523 and anti-slip members 523, the spacer bar 522 and the anti-slip member 523 can apply a pulling force to each circle of the core wire wound on the motor stator, so that the core wire is evenly stressed, thereby ensuring the tightening effect of the core wire.

[0025] like Figure 7-8 and Fig.10 As shown, the anti-slip part 523 includes multiple sets of anti-slip wheels 5231 and torsion springs 5232; the multiple sets of anti-slip wheels 5231 are rotatably connected to the clamping block 521, one end of the torsion spring 5232 is set at the end of the clamping block 521, and the other end of the torsion spring 5232 is connected to the clamping block 521.

[0026] It should be noted that in order to prevent the clamping block 521 from excessively pulling the core wire and causing the core wire to be tightened too much, as the friction force on the anti-skid wheel 5231 increases, the torsion spring 5232 is compressed, allowing the anti-skid wheel 5231 to rotate a certain amount so that the clamping block 521 can continue to descend.

[0027] like Fig.10 As shown, a limit block 5233 is provided at the end of the torsion spring 5232 away from the anti-slip wheel 5231, and the clamping block 521 (such as Figure 7 As shown in the figure, a plurality of limiting grooves 5234 are arranged at intervals on the upper circumference, and the center of the circle formed by the plurality of limiting grooves 5234 coincides with the axis of the limiting block 5233, and the limiting block 5233 is inserted into one of the limiting grooves 5234.

[0028] It should be noted that in order to further prevent the core wire from being pulled too hard, when the torsion spring 5232 is subjected to excessive force, the limit block 5233 will be separated from one of the limit slots 5234. At this time, the compressed torsion spring 5232 will be twisted to a certain extent, and the elastic force will decrease until the limit block 5233 is plugged into the other limit slot 5234. That is, whenever the torsion spring 5232 is subjected to excessive force, the limit block 5233 will be separated from the limit slot 5234, so that the torsion spring 5232 will loosen the rotation restriction on the anti-skid wheel 5231 to a certain extent, so as to prevent excessive pulling of the core wire.

[0029] like Figure 8-9 As shown, the clamping mechanism 52 (such as Figure 3 The force limiting mechanism 524 includes a slide plate 5241 and a second compression spring 5242; the slide plate 5241 is slidably connected to the clamping block 521 (as shown in FIG. Figure 7As shown in the figure), the sliding direction of the slide plate 5241 is the same as or opposite to the direction in which the driving member 51 drives the clamping block 521 to move, and the second compression spring 5242 is arranged between the clamping block 521 and the slide plate 5241.

[0030] It should be noted that when the driving member 51 (such as Figure 3 When the clamping mechanism 52 is driven to move toward the motor stator, the second compression spring 5242 is first compressed until the second compression spring 5242 is compressed to a certain extent. Then the clamping mechanism 52 is driven to push the core wire to move along its winding direction to be tight, thereby forming a force buffering structure to prevent the core wire from being damaged by excessive force in a short period of time due to the driving member 51 being driven too fast.

[0031] like Figure 5-7 As shown, the clamping mechanism 52 includes an adjustment mechanism 526 and two clamping blocks 521; the position control mechanism 525 is used to adjust the distance between the two clamping blocks 521; the adjustment mechanism 526 is used to drive the two clamping blocks 521 to move in opposite directions to push the core wire wound on the motor stator to tighten.

[0032] It should be noted that when there are two clamping blocks 521, when the clamping blocks 521 push the core wire wound on the motor stator to be tightened, the clamping blocks 521 are on opposite sides of the wound core wire, that is, at this time, the two clamping blocks 521 need to move in opposite directions to drive the core wire to be tightened; by the coordinated use of the two clamping blocks 521, both sides of each circle of the core wire are pulled by the friction force of the clamping blocks 521, thereby further improving the uniformity of the force on the core wire; that is, when in use, after the position control mechanism 525 drives the two clamping blocks 521 to clamp the core wire from both sides of the wound core wire, the two clamping blocks 521 are driven to move in opposite directions through the adjustment mechanism 526, so that the force on the core wire is consistent with its winding direction, thereby achieving the purpose of tightening the core wire.

[0033] like Figure 5-7As shown, the position control mechanism 525 includes a second mounting seat 5251, a driving mechanism, two sliders 5253 and a first rotating rod 5254; the second mounting seat 5251 is arranged between the output end of the driving member 51 and the clamping block 521, the two sliders 5253 are respectively connected to the two clamping blocks 521, and the second mounting seat 5251 is provided with a first slide groove 5252, and the first slide groove 5252 is an arc groove structure, and the arc center of the first slide groove 5252 coincides with the axis of the motor stator; One end of the two first rotating rods 5254 is hinged to the second mounting seat 5251, and the hinge point between the first rotating rod 5254 and the second mounting seat 5251 is located at the arc center of the first slide groove 5252; the driving mechanism is installed on the second mounting seat 5251, and the output end of the driving mechanism is connected to the first rotating rod 5254; the driving mechanism is used to drive the two first rotating rods 5254 to move closer to or away from each other; a cover plate is fixed on the top of the second mounting seat 5251, and the driving member 51 (such as Figure 3 The output end of the driving member 51 is connected to the cover plate. By setting the cover plate, the output end of the driving member 51 can be connected to the center position of the second mounting seat 5251, thereby ensuring the pressure stability of the driving member 51 on the second mounting seat 5251.

[0034] It should be noted that when it is necessary to adjust the distance between the clamping block 521 and the core wire wound on the motor stator, the two first rotating rods 5254 are driven to move closer to or farther from each other through the driving mechanism, and the two sliders 5253 are driven to move closer to or farther from each other through the first rotating rod 5254, thereby driving the clamping block 521 and the core wire closer to or farther from each other. When the core wire is wound with different numbers of turns, the two clamping blocks 521 can be driven to clamp the two sides of the core wire; by driving the clamping block 521 to rotate along the axis of the motor stator, when the clamping block 521 clamps the core wire, the clamping block 521 is always relatively parallel to the axial direction of the spiral core wire wound on the motor stator, so that the pressure on each turn of the core wire is close to the same, thereby ensuring uniform force on the core wire.

[0035] like Figure 6-7 As shown, the driving mechanism includes a first electric push rod 5255, a connecting shaft 5257 and two second rotating rods 5258; the first electric push rod 5255 is installed on the second mounting seat 5251, and the second mounting seat 5251 is provided with a second slide groove 5256, and the second slide groove 5256 is arranged along the radial direction of the motor stator, one end of the connecting shaft 5257 is connected to the output end of the first electric push rod 5255, and the connecting shaft 5257 is slidably connected to the second slide groove 5256, one end of the two second rotating rods 5258 is respectively hinged to the two first rotating rods 5254, and the other end of the two second rotating rods 5258 is hinged to the connecting shaft 5257.

[0036] It should be noted that the first electric push rod 5255 drives the connecting shaft 5257 to slide on the second slide groove 5256, and the connecting shaft 5257 drives the two second rotating rods 5258 to rotate, and the second rotating rods 5258 drive the two first rotating rods 5254 to rotate around the motor stator axis as the center, thereby achieving the purpose of adjusting the position between the two clamping blocks 521.

[0037] like Figure 6-7 As shown, the adjustment mechanism 526 includes a mounting block 5261 and a second electric push rod 5262; one end of the mounting block 5261 is fixed to the slider 5253, and the other end of the mounting block 5261 is slidably connected to the clamping block 521; the second electric push rod 5262 is arranged on the mounting block 5261, and the output end of the second electric push rod 5262 is connected to the clamping block 521; a slide rail 5263 is arranged on the clamping block 521, and a third slide groove adapted to the slide rail 5263 is opened on the mounting block 5261.

[0038] It should be noted that when the position control mechanism 525 drives the clamping block 521 to clamp the two sides of the core wire wound on the motor stator, the adjustment mechanism 526 drives the two clamping blocks 521 to move in opposite directions, so as to achieve the purpose of driving the core wire to move in the winding direction and tighten. Specifically, when the driving member 51 (such as Figure 3 When the two clamping blocks 521 are driven to move along the axis of the motor stator, the second electric push rod 5262 drives one of the clamping blocks 521 to move in the opposite direction, ensuring that the movement direction of the two clamping blocks 521 is close to the winding direction of the core wire at the contact position between the clamping blocks 521 and the core wire, thereby achieving the purpose of pushing the core wire to tighten.

[0039] like Figure 1-11 As shown, a winding method for a motor stator winding device comprises the following steps: Step 1: stator winding: firstly, the motor stator is positioned and mounted on the first mounting seat 2, and then, under the guidance of the guide mechanism 4, the core wire is wound on the motor stator through the winding mechanism 3; Step 2, adjusting the tension: after winding a certain number of turns of the core wire on the motor stator, the winding mechanism 3 stops, and the adjusting mechanism 5 is started, and the driving member 51 drives the clamping mechanism 52 to contact the core wire wound on the motor stator, and pushes the core wire to continue to move in the winding direction to increase its tension; then the driving member 51 drives the clamping mechanism 52 to move upward and reset, and the winding mechanism 3 continues to wind the core wire on the motor stator, so that the winding tension of the core wire is adjusted in the process of winding the core wire; In order to ensure precise control of the tension of the core wire, a tension sensor for detecting the tension of the core wire can be installed on the winding mechanism 3. When the tension of the core wire wound on the motor stator is adjusted by the adjustment mechanism 5, the tension of the core wire connected to the winding mechanism 3 will decrease. When the tension sensor detects that the tension of the core wire has decreased, the core wire can be further tightened by the winding mechanism 3 to ensure that the core wire is in a suitable tension state when it continues to be wound. It can be understood that the winding mechanism 3, the guide mechanism 4 and the tension sensor are all existing technologies, and the tension sensor is not drawn in the figure and will not be described in detail.
