Description

Technical Field

[0001] The utility model relates to the field of stator processing, in particular to a wire hooking mechanism for a stator winding machine. Background Art

[0002] The stator consists of an outer ring and multiple frames arranged within it. The frames are evenly distributed along the inner circumference of the outer ring, and multiple coils are wound around the frames. The wire is a relatively hard metal wire, so the coils require a winding machine.

[0003] The winding machine includes a clamp for clamping the stator, a feeding device for feeding wire and a winding device. A clamping piece is also provided around the clamp to clamp one end of the wire to assist the winding device in winding.

[0004] When winding the wire, after a copper wire is wound around the first frame, it needs to be wound around the third, fourth or fifth frame. In other words, adjacent frames cannot be wound around the same copper wire. However, if the copper wire jumps over the adjacent frames, it is easy for the copper wire to abut against the coil on the adjacent frame, causing a short circuit. Therefore, the copper wire needs to be wound around the outer ring of the outer ring, and then bent so that the copper wire sticks to the outer wall of the outer ring and extends to the next frame to be wound. It is then bent again so that the copper wire is bent back into the stator and wound again. The ends of the coils on the two adjacent frames are separated by the insulation properties of the outer ring.

[0005] The applicant believes that pulling one end of the copper wire outside the stator requires the winding device to perform a complex telescopic movement and identification movement, which makes the winding device structure complicated and also makes the operating state of the winding device of the entire winding machine very complicated. Utility Model Content

[0006] In order to simplify the structure of the winding device, the auxiliary copper wire outer winding action of the winding device is isolated and operated. Therefore, the utility model provides a wire hooking mechanism for a stator winding machine.

[0007] The utility model provides a wire hooking mechanism for a stator winding machine adopts the following technical solutions:

[0008] A wire hooking mechanism for a stator winding machine is used to cooperate with a stator having a plurality of notches on the outer ring, wherein the plurality of notches correspond to a plurality of skeletons respectively, and the notches can be used to limit the position of the copper wire; the wire hooking mechanism for the stator winding machine includes a wire hooking part, a driving member and a moving assembly, the wire hooking part is arranged on the moving assembly, the wire hooking part is provided with a limiting groove for threading, the limiting groove has threading openings on both sides along the wire feeding direction, the limiting groove also has an outlet, and the outlet is connected to the threading opening; the moving assembly is used to drive the wire hooking part to move on the X-axis and the Y-axis, the wire hooking part is rotatably connected to the moving assembly, and the driving member drives the wire hooking part to rotate so that the limiting groove moves to the outside of the stator.

[0009] After the wire is wound on a skeleton, the wire extends along the final winding direction and is in a vertical drooping state. At this time, the moving component drives the wire hook part to move along the X-axis until the lead-out port is opposite to the end of the copper wire in the drooping state, and then drives the wire hook part. The driving part starts and causes the wire hook part to rotate so that the lead-out port of the limiting groove is opposite to the drooping position of the copper wire. Then the moving component moves the wire hook part again so that the wire hook part is close to the copper wire and the copper wire is embedded in the limiting groove. Then the driving part drives the wire hook part to rotate, which changes the direction of the lead-out port. At the same time, the groove wall of the wire hook part pushes the copper wire to move, so that the limiting groove part of the wire hook part rotates to the outside of the stator, thereby hooking the copper wire from the inside of the stator to the outside of the stator outer ring, so that the copper wire passes through the gap corresponding to the skeleton to the outside of the outer ring, completing one wire hooking, thereby isolating the wire hooking action to the outside of the stator, which is conducive to simplifying the complexity of the overall device and making the structure more concise.

[0010] Then the fixture holding the stator rotates synchronously with the stator, and the next skeleton that needs to hook the wire is rotated to a position close to the wire hooking part. Since the copper wire is in a straight state, when the fixture rotates, the copper wire adheres to the outer wall of the stator and extends to the next notch. Then the driving part drives the wire hooking part to rotate to its initial state, thereby bringing one end of the copper wire into the stator. At the same time, the wire hooking part is reset, and the moving component can drive the wire hooking part to retreat for the next wire hooking action, making the action of hooking the wire and winding it around the outer ring easier.

[0011] Preferably, the line hooking portion is further connected to an extension portion, the extension portion is connected to the driving member, and the extension portion is provided on the moving component.

[0012] Since there are other structures and devices between the moving component and the stator clamp, and the structure at the stator clamp is relatively complex, providing an extension portion can move the moving component and the driving component to a position farther away from the stator clamp, making the structure of the entire wire hooking machine less likely to interfere with each other and making the overall structural layout more reasonable.

[0013] Preferably, the driving member includes a base, a cylinder, a driving rod and a connecting rod, and the base is connected to the moving assembly;

[0014] The extended portion is a driving rod, the length of the driving rod is greater than the connecting rod, the driving rod is connected to the cylinder output shaft, the line hooking portion includes a linkage plate, one end of the connecting rod is rotatably connected to the linkage plate, the other end of the connecting rod is fixed on the base, the end of the driving rod away from the cylinder is rotatably connected to the linkage plate, and the cylinder is rotatably connected to the base.

[0015] When the cylinder is activated, the drive rod telescopes, pushing the linkage plate, causing it to change position. One end of the linkage plate is restricted by the movement of the connecting rod, causing the linkage plate to rotate while pushing the end of the drive rod away. The arrangement of the drive rod and the connecting rod not only promotes the rotation of the linkage plate but also serves as an extension of the space provided by the restriction slot. Incorporating the extension into the driver simplifies the structure. While the extension creates a longer distance between the wire hooking unit and the cylinder, the actual rotation point of the wire hooking unit is at the end of the drive rod, minimizing the length of the copper wire hooked, making it easier to thread the wire back into the stator later.

[0016] Preferably, the linkage plate is a rectangular plate, the ends of the connecting rod and the driving rod are respectively arranged at two vertex corners of the diagonal line of the linkage plate, and the connecting rod is provided with an avoidance groove, which is used to avoid the linkage plate.

[0017] The diagonals of the rectangular plate are the two places with the largest spacing inside the rectangular plate. Placing the ends of the connecting rod and the driving rod at the two top corners is conducive to reducing the volume required for the linkage plate, further simplifying the wire hooking device, and making the movement of the wire hooking part more flexible.

[0018] Preferably, the line hooking portion further includes a wire wheel, which is arranged at another top corner of the linkage plate, and the limiting groove is recessed in the middle of the outer periphery of the wire wheel, and the limiting groove extends circumferentially along the outer periphery of the wire wheel.

[0019] The limiting groove is recessed in the peripheral wall of the wire wheel, and the edges of multiple openings are transitioned into arcs. When the wire hooking part rotates, there is a certain sliding friction between the copper wire and multiple surfaces and edges of the limiting groove, which is beneficial to reducing the friction between the copper wire and the edges of the limiting groove when the wire hooking part rotates, thereby reducing the wear of the copper wire and protecting the copper wire.

[0020] Furthermore, when assembling the thread hooking part, the ring shape of the limiting groove makes it unnecessary to adjust the direction of the thread hooking part during assembly, making the assembly operation simpler and faster.

[0021] Preferably, the linkage plates are provided with two pieces, the end of the connecting rod and the end of the driving rod are both clamped between the two linkage plates, a mounting plate is further provided on the side of the spool away from the linkage plate, a wheel axle is fixedly connected to the center of the spool, a connecting plate is provided between the two linkage plates, the wheel axle is threadedly connected to the connecting plate, a nut is threadedly connected to the end of the wheel axle away from the connecting plate, and the nut presses the mounting plate against the side wall of the spool.

[0022] Preferably, when the elongation of the driving rod reaches a maximum, the linkage plate is perpendicular to the connecting rod; when the elongation of the driving rod reaches a minimum, the linkage plate is parallel to the connecting plate.

[0023] In summary, the present invention has the following beneficial technical effects:

[0024] After the wire is wound on a skeleton, the wire extends along the final winding direction and is in a vertical drooping state. At this time, the moving component drives the wire hook part to move along the X-axis until the lead-out port is opposite to the end of the copper wire in the drooping state, and then drives the wire hook part. The driving part starts and causes the wire hook part to rotate so that the lead-out port of the limiting groove is opposite to the drooping position of the copper wire. Then the moving component moves the wire hook part again so that the wire hook part is close to the copper wire and the copper wire is embedded in the limiting groove. Then the driving part drives the wire hook part to rotate, which changes the direction of the lead-out port. At the same time, the groove wall of the wire hook part pushes the copper wire to move, so that the limiting groove part of the wire hook part rotates to the outside of the stator, thereby hooking the copper wire from the inside of the stator to the outside of the stator outer ring, so that the copper wire passes through the gap corresponding to the skeleton to the outside of the outer ring, completing one wire hooking, thereby isolating the wire hooking action to the outside of the stator, which is conducive to simplifying the complexity of the overall device and making the structure more concise.

[0025] Then the fixture holding the stator rotates synchronously with the stator, and the next skeleton that needs to hook the wire is rotated to a position close to the wire hooking part. Since the copper wire is in a straight state, when the fixture rotates, the copper wire adheres to the outer wall of the stator and extends to the next notch. Then the driving part drives the wire hooking part to rotate to its initial state, thereby bringing one end of the copper wire into the stator. At the same time, the wire hooking part is reset, and the moving component can drive the wire hooking part to retreat for the next wire hooking action, making the action of hooking the wire and winding it around the outer ring easier.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 The utility model is described in further detail.

[0031] The embodiment of the utility model discloses a wire hooking mechanism for a stator winding machine.

[0032] Reference Figure 1 , a wire hooking mechanism for a stator winding machine, used to cooperate with a stator 2 with multiple notches on the outer ring 22, the multiple notches corresponding to multiple skeletons 21, and the notches can be used to limit the position of the copper wire; the wire hooking mechanism for the stator 2 winding machine includes a wire hooking part 4, a driving part 5 and a moving component, the wire hooking part 4 is arranged on the moving component, the wire hooking part 4 is provided with a limiting groove 41 for threading, the limiting groove 41 has threading openings on both sides along the wire feeding direction, the limiting groove 41 also has a guide outlet, and the guide outlet is connected to the threading opening; the moving component is used to drive the wire hooking part 4 to move on the X-axis and Y-axis, the wire hooking part 4 is rotatably connected to the moving component, and the driving part 5 drives the wire hooking part 4 to rotate so that the limiting groove 41 moves to the outside of the stator 2.

[0033] After the wire is wound on a skeleton 21, the wire extends along the final winding direction and is in a vertical drooping state. At this time, the moving component drives the wire hook part 4 to move along the X-axis until the outlet is opposite to the end of the copper wire in the drooping state, and then drives the wire hook part 4, the driving part 5 starts and causes the wire hook part 4 to rotate, so that the outlet of the limiting groove 41 is opposite to the drooping position of the copper wire, and then the moving component moves the wire hook part 4 again, so that the wire hook part 4 is close to the copper wire and the copper wire is embedded in the limiting groove 41, and then the driving part 5 drives the wire hook part 4 to rotate, which can change the direction of the outlet. At the same time, the groove wall of the wire hook part 4 pushes the copper wire to move, so that the limiting groove 41 part of the wire hook part 4 rotates to the outside of the stator 2, thereby hooking the copper wire from the inside of the stator 2 to the outside of the outer ring 22 of the stator 2, so that the copper wire passes through the gap corresponding to the skeleton 21 to the outside of the outer ring 22, completing one wire hooking, thereby isolating the wire hooking action to the outside of the stator 2, which is conducive to simplifying the complexity of the overall device and making the structure more concise.

[0034] Then the clamp 3 holding the stator 2 rotates synchronously with the stator 2, and the next skeleton 21 that needs to hook the wire is rotated to a position close to the wire hooking part 4. Since the copper wire is in a straight state, when the clamp 3 rotates, the copper wire adheres to the outer wall of the stator 2 and extends to the next notch. Then the driving member 5 drives the wire hooking part 4 to rotate to the initial state, thereby bringing one end of the copper wire into the stator 2. At the same time, the wire hooking part 4 is reset, and the moving component can drive the wire hooking part 4 to retreat for the next wire hooking action, making the wire hooking and winding around the outer ring 22 easier.

[0035] Reference Figure 2 as well as Figure 3 In this embodiment, the line hooking portion 4 is further connected to an extension portion, which is connected to the driving member 5 and is provided on the moving component.

[0036] Since there are other structures and devices between the moving component and the stator 2 clamp 3, and the structure at the stator 2 clamp 3 is relatively complex, the provision of an extension portion can move the moving component and the driving member 5 to a position farther away from the stator 2 clamp 3, making it less likely that the structure of the overall wire hooking machine will interfere with each other, and making the overall structural layout more reasonable.

[0037] Reference Figure 2 as well as Figure 3 In this embodiment, the driving member 5 includes a base 51, a cylinder 52, a driving rod 53 and a connecting rod 54, and the base 51 is connected to the moving assembly;

[0038] The extended part is a driving rod 53, the length of the driving rod 53 is greater than the connecting rod 54, the driving rod 53 is connected to the output shaft of the cylinder 52, the line hooking part 4 includes a linkage plate 55, one end of the connecting rod 54 is rotatably connected to the linkage plate 55, and the other end of the connecting rod 54 is fixed on the base 51, the end of the driving rod 53 away from the cylinder 52 is rotatably connected to the linkage plate 55, and the cylinder 52 is rotatably connected to the base 51.

[0039] The activation of the cylinder 52 causes the drive rod 53 to telescope, thereby pushing the linkage plate 55, causing the linkage plate 55 to change its position. One end of the linkage plate 55 is restricted by the movement of the connecting rod 54. The linkage plate 55 pushes the end of the drive rod 53 away while rotating. The arrangement of the drive rod 53 and the connecting rod 54 not only promotes the rotation of the linkage plate 55, but also serves as an extension of the space provided by the restriction groove 41. Incorporating the extension into the driver 5 facilitates a simplified structure. Although the extension creates a longer distance between the wire hooking portion 4 and the cylinder 52, the actual rotation point of the wire hooking portion 4 is at the end of the drive rod 53, which reduces the length of the copper wire hooked, making it easier to thread the wire into the stator 2 later.

[0040] Reference Figure 2 as well as Figure 3In this embodiment, the linkage plate 55 is a rectangular plate, and the ends of the connecting rod 54 and the driving rod 53 are respectively arranged at the two top corners of the diagonal line of the linkage plate 55. The connecting rod 54 has an avoidance groove 6, which is used to avoid the linkage plate 55.

[0041] The diagonals of the rectangular plate are the two places with the largest internal spacing. Placing the ends of the connecting rod 54 and the driving rod 53 at the two vertex corners is beneficial to reducing the volume required for the linkage plate 55 and further simplifying the line hooking device.

[0042] Reference Figure 2 as well as Figure 3 In this embodiment, the line hooking part 4 also includes a line wheel 42, which is arranged at another top corner of the linkage plate 55, and the limiting groove 41 is recessed in the middle of the outer periphery of the line wheel 42, and the limiting groove 41 extends circumferentially along the outer periphery of the line wheel 42 to form an annular groove.

[0043] The limiting groove 41 is recessed in the peripheral wall of the wire wheel 42, and the arc transition has multiple opening edges. When the wire hooking part 4 rotates, there is a certain sliding friction between the copper wire and multiple surfaces and edges of the limiting groove 41, which is beneficial to reducing the friction between the copper wire and the edges of the limiting groove 41 when the wire hooking part 4 rotates, thereby reducing the wear of the copper wire and protecting the copper wire.

[0044] Furthermore, when assembling the thread hooking portion 4 , the ring shape of the limiting groove 41 eliminates the need to adjust the direction of the thread hooking portion 4 during assembly, making the assembly operation simpler and faster.

[0045] Reference Figure 2 as well as Figure 3 In this embodiment, there are two linkage plates 55, and the end of the connecting rod 54 and the end of the driving rod 53 are clamped between the two linkage plates 55. A mounting plate 43 is also provided on the side of the spool 42 away from the linkage plate 55. The center of the spool 42 is fixedly connected to a wheel axle, and a connecting plate is provided between the two linkage plates 55. The wheel axle is threadedly connected to the connecting plate. A nut 44 is threadedly connected to the end of the wheel axle away from the connecting plate. The nut 44 presses the mounting plate 43 against the side wall of the spool 42.

[0046] Reference Figure 2 as well as Figure 3 In this embodiment, when the elongation of the driving rod 53 reaches the maximum, the linkage plate 55 is perpendicular to the connecting rod 54; when the elongation of the driving rod 53 reaches the minimum, the linkage plate 55 is parallel to the connecting plate.

[0047] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
