Description

Technical Field

[0001] The present invention relates to the technical field of stator coil winding, and particularly relates to a motor stator winding device and a winding method thereof. Background Art

[0002] The stator is a fixed component in a motor, which consists of a stator core, a stator winding, and a 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 action of magnetic lines of force, thereby realizing mechanical motion or outputting current.

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

[0004] However, there are still some problems in the use of the above-mentioned motor stator winding device:

[0005] Due to the complex structure of the inner wall of the stator, it poses a great obstacle to the coil winding work, and the winding device has high requirements for the tension of the core wire; when the core wire wound by the winding device becomes loose or the core wires are multi-layered and staggered, the wound coil will become somewhat loose, 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 winding is completed, due to the certain toughness and friction of the core wire, although the head and tail ends of the core wire winding are in a tensioned state, the middle position of the core wire winding may still be in a loose state, thereby causing problems such as insufficient contact between the core wires and affecting the winding effect.

Detailed implementation manners

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] As Figures 1 - 10 shown, a motor stator winding device, as Figures 1 - 3 shown, includes a chassis 1 and a first mounting seat 2 for placing a motor stator. A wire winding mechanism 3 and a guiding mechanism 4 are arranged on the chassis 1; the wire winding mechanism 3 winds the core wire around the motor stator; the guiding mechanism 4 is used to provide guidance when the core wire is wound; an adjusting mechanism 5 for tightening the core wire wound around the motor stator is arranged on the chassis 1; the adjusting 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; a clamping mechanism 52, and the clamping mechanism 52 is arranged above the wire 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 around the motor stator, the clamping mechanism 52 is used to drive the core wire to move along its winding direction, driving each turn of the core wire with different turns wound around the motor stator to move synchronously along its winding direction to tighten the core wire.

[0045] It should be noted that during the process of winding the core wire around the motor stator, when the core wire is wound 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 around the motor stator. The clamping mechanism 52 is used to push the core wire to continue moving along the winding direction of the core wire, so as to improve the tightness of the core wire wound on the motor stator. By pushing the core wire with the clamping mechanism 52, each turn of the core wire wound around the motor stator with different numbers of turns can be driven to move synchronously along its winding direction, so that its overall tightness is adjusted, rather than adjusting the tightness by dragging the end of the core wire, ensuring that the force on the core wire wound around the motor stator is relatively uniform.

[0046] As Figures 1 - 5 and Figure 8 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, and the distance between adjacent spacer bars 522 is equal to the distance between adjacent core wires wound around the motor stator. 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 around the motor stator in the radial cross-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, it can push the deformation part and the mounting bar 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.

[0047] It should be noted that when it is necessary to adjust the tightness of the core wire, the position control mechanism 525 is used to push the clamping block 521 closer to the core wire wound around the motor stator, so that the clamping mechanism 52 moves to the adjacent position of each turn of the core wire, so that the spacer bar 522 can push the core wire to be regularly arranged, and at the same time, the core wire can be accurately aligned with the anti-slip member 523; when the spacer bar 522 contacts the core wire, the increase in the pressure between the spacer bar 522 and the core wire will cause the deformation part to deform, pushing the core wire to move to both sides, achieving the purpose of adjusting the arrangement position of the core wire. 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 contacts the core wire;

[0048] At this time, the driving member 51 drives the clamping mechanism 52 to descend, so that the spacer 522 and the anti-slip member 523 move downward, and the core wire is pulled by the frictional force between the spacer 522, the anti-slip member 523 and 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 the anti-slip member 523, a pulling force can be applied to each turn of the core wire wound on the motor stator by the spacer 522 and the anti-slip member 523, so that the core wire is uniformly stressed and the tightness effect of the core wire is ensured.

[0049] As Figures 7 - 8 and Figure 10 shown, the anti-slip member 523 includes multiple groups of anti-slip wheels 5231 and torsion springs 5232; multiple groups of anti-slip wheels 5231 are rotatably connected to the clamping block 521, one end of the torsion spring 5232 is arranged at the end of the clamping block 521, and the other end of the torsion spring 5232 is connected to the clamping block 521.

[0050] It should be noted that in order to prevent the clamping block 521 from excessively pulling the core wire and making the tension of the core wire too large, as the frictional force received by the anti-slip wheel 5231 increases, the torsion spring 5232 is compressed by the force, allowing the anti-slip wheel 5231 to rotate to a certain extent so that the clamping block 521 can continue to descend.

[0051] As Figure 10 shown, a limit block 5233 is arranged at the end of the torsion spring 5232 away from the anti-slip wheel 5231, and a plurality of limit grooves 5234 are arranged at intervals on the circumference of the clamping block 521 (as Figure 7 shown), and the center of the circle formed by the plurality of limit grooves 5234 coincides with the axis of the limit block 5233, and the limit block 5233 is inserted into one of the limit grooves 5234.

[0052] It should be noted that in order to further prevent the pulling force on the core wire from being too large, when the torsion spring 5232 is stressed too much, the limit block 5233 will be separated from one of the limit grooves 5234. At this time, the compressed torsion spring 5232 will twist to a certain extent and the elastic force will decrease until the limit block 5233 is inserted into another limit groove 5234. That is, whenever the torsion spring 5232 is stressed too much, the limit block 5233 will be separated from the limit groove 5234, so that the torsion spring 5232 will loosen the rotation restriction on the anti-slip wheel 5231 to a certain extent to prevent excessive pulling on the core wire.

[0053] As Figures 8 - 9 shown, the clamping mechanism 52 (as Figure 3 shown) further includes a force limiting mechanism 524, and 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 Figure 7As shown, the sliding direction of the sliding 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 disposed between the clamping block 521 and the sliding plate 5241.

[0054] It should be noted that when the driving member 51 (such as Figure 3 As shown) drives the clamping mechanism 52 to move closer to the motor stator, the second compression spring 5242 is first compressed by force. It is not until the second compression spring 5242 is compressed to a certain extent that the clamping mechanism 52 will be driven to push the core wire to move and tighten along its winding direction, forming a force buffer structure to prevent the problem that the core wire is damaged due to excessive force in a short time caused by the driving member 51 driving too fast.

[0055] Such as Figures 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 around the motor stator to be tightened.

[0056] It should be noted that when there are two clamping blocks 521, when the clamping blocks 521 push the core wire wound around the motor stator to be tightened, the clamping blocks 521 are on the 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 using the two clamping blocks 521 in cooperation, the two sides of each turn of the core wire are both pulled by the frictional force of the clamping blocks 521, further improving the uniformity of the force on the core wire; that is, in use, when 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 adjustment mechanism 526 drives the two clamping blocks 521 to move in opposite directions, so that the force on the core wire is consistent with its winding direction, achieving the purpose of tightening the core wire.

[0057] Such as Figures 5 - 7As shown, the position control mechanism 525 includes a second mounting base 5251, a driving mechanism, two sliders 5253 and a first rotating rod 5254; the second mounting base 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, a first sliding groove 5252 is formed on the second mounting base 5251, and the first sliding groove 5252 is an arc-shaped groove structure, and the arc center of the first sliding groove 5252 coincides with the axis of the motor stator; one ends of the two first rotating rods 5254 are both hinged to the second mounting base 5251, and the hinge point between the first rotating rod 5254 and the second mounting base 5251 is located at the arc center position of the first sliding groove 5252; the driving mechanism is mounted on the second mounting base 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 approach or separate from each other; a cover plate is fixedly provided at the top of the second mounting base 5251, and the output end of the driving member 51 (such as Figure 3 shown) is connected to the cover plate. Through the setting of the cover plate, the output end of the driving member 51 can be connected to the center position of the second mounting base 5251, ensuring the pressure stability of the driving member 51 on the second mounting base 5251.

[0058] It should be noted that when it is necessary to adjust the distance between the clamping block 521 and the core wire wound around the motor stator, the driving mechanism is used to drive the two first rotating rods 5254 to approach or separate from each other, and the two first rotating rods 5254 drive the two sliders 5253 to approach or separate from each other, thereby driving the clamping block 521 and the core wire to approach or separate from each other. When the core wire is wound in different numbers of turns, the two clamping blocks 521 can be driven to clamp both 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 axially parallel to the spiral core wire wound around the motor stator, so that the pressure received by each turn of the core wire approaches the same, ensuring the uniformity of the force on the core wire.

[0059] As Figures 6 - 7 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 mounted on the second mounting base 5251, a second sliding groove 5256 is formed on the second mounting base 5251, and the second sliding 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 sliding groove 5256. One ends of the two second rotating rods 5258 are respectively hinged to the two first rotating rods 5254, and the other ends of the two second rotating rods 5258 are hinged to the connecting shaft 5257.

[0060] It should be noted that the first electric push rod 5255 drives the connecting shaft 5257 to slide on the second chute 5256. 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 axis of the motor stator, so as to achieve the purpose of adjusting the position between the two clamping blocks 521.

[0061] As Figures 6 - 7 shown in the figure, the adjustment mechanism 526 includes a mounting block 5261 and a second electric push rod 5262; one end of the mounting block 5261 is fixedly arranged on 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 chute adapted to the slide rail 5263 is opened on the mounting block 5261.

[0062] It should be noted that when the clamping block 521 is driven by the position control mechanism 525 to clamp both sides of the core wire wound around 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 along the winding direction and tighten; specifically, when the two clamping blocks 521 are driven by the driving member 51 (as Figure 3 shown in the figure) to move along the axis of the motor stator, one of the clamping blocks 521 is driven by the second electric push rod 5262 to move in the opposite direction, so as to ensure that the moving directions of the two clamping blocks 521 are approximately the same as the winding direction of the core wire at the contact position between the clamping block 521 and the core wire, and further achieve the purpose of pushing the core wire to tighten.

[0063] As Figures 1 - 11 shown in the figure, a winding method of a motor stator winding device includes the following steps:

[0064] Step 1, stator winding: First, the motor stator is positioned and installed on the first mounting seat 2, and then under the guidance of the guiding mechanism 4, the core wire is wound around the motor stator through the winding mechanism 3;

[0065] Step 2, tension adjustment: After winding a certain number of turns of the core wire on the motor stator, the winding mechanism 3 stops, and the adjustment mechanism 5 is started. The clamping mechanism 52 is driven by the driving member 51 to contact the core wire wound around the motor stator, and the core wire is pushed to continue moving in its winding direction to increase its tension; then the clamping mechanism 52 is driven by the driving member 51 to move upward and reset, and the winding mechanism 3 continues to wind the core wire on the motor stator, so as to adjust the winding tension of the core wire during the process of winding the core wire.

[0066] To ensure the precise control of the tension of the core wire, a tension sensor for detecting the tension force of the core wire can be installed on the winding mechanism 3. After adjusting the tension of the core wire wound around the motor stator through the adjusting mechanism 5, the tension of the core wire connected to the winding mechanism 3 will decrease. When the tension sensor detects the decrease in the tension of the core wire, the core wire can be further tightened through the winding mechanism 3 to ensure that the core wire is in a suitable tension state when continuing to wind; it can be understood that the winding mechanism 3, the guiding mechanism 4, and the tension sensor are all prior arts, and the tension sensor is not shown in the figure and will not be elaborated in detail.
