Description

Technical Field

[0001] This utility model belongs to the technical field of winding equipment, and in particular relates to a stator winding mechanism. Background Technology

[0002] A winding device is a key automated piece of equipment in the field of motor manufacturing used to automatically wind coils (such as copper wire or enameled wire) onto a stator core to form a winding, aiming to improve winding efficiency and quality consistency. Existing mainstream automated winding devices typically include a winding head with multi-degree-of-freedom (such as translation along the X, Y, and Z axes, and sometimes rotation) motion (its front end is equipped with a wire guide and conveyor mechanism for guiding and feeding the wire) and a clamp for holding and positioning the stator core. The stator is usually fixed in a manner where its axial direction (such as the Z-axis) is parallel or perpendicular to the main motion plane of the winding head (such as the XY plane). The control system drives the winding head to guide the wire through the stator slots or around the teeth according to a preset trajectory. However, existing devices of this type have fundamental technical flaws when winding operations are required on the outer side of the stator, especially the bottom area adjacent to its mounting base: the winding head, wire nozzle, and their associated mechanisms are prone to physical interference with the stator bottom structure (such as mounting flanges, cooling fins, and protruding parts at the bottom of the core), clamps, or worktable; at the same time, the space in this bottom area is extremely small, and the winding device is limited by its own size and motion estimation, making it difficult to operate effectively in depth. Furthermore, the wire nozzle has accessibility and functional defects due to insufficient length, angle adaptability, or rigidity, making it impossible to reliably extend into the bottom slit or flexibly perform actions such as wire feeding and hanging; in addition, this area is often a blind spot for visual monitoring, making precise control difficult and increasing the risk of errors. To address this problem, existing technologies typically adopt undesirable compromises such as sacrificing stator design optimization (affecting electromagnetic performance), relying on inefficient manual rewinding (reducing efficiency, increasing costs, and unstable quality), or using expensive and complex multi-axis equipment (whose reliability, accuracy, and anti-collision capabilities remain questionable). Therefore, existing winding devices have the technical problem of being unable to reliably, efficiently, and with high quality complete the automated winding operation of the bottom area of ​​the stator's outer side.

[0014] The stator winding mechanism provided in this embodiment of the present invention has at least one of the following technical effects: The stator winding mechanism of this utility model is assembled from a mounting base, a stator mounting device, a wire end fixing device, a wire pressing device, a wire cutting device, a moving adjustment device, and a winding device. The moving adjustment device has horizontal position movement and lifting adjustment. The winding device is assembled from a mounting plate, a motor, a slider, a connecting rod, a sleeve, and a rotating block. During assembly, the stator mounting device, wire end fixing device, wire pressing device, wire cutting device, and moving adjustment device are all mounted on the mounting base. The moving adjustment device, stator mounting device, wire pressing device, wire end fixing device, and wire cutting device are arranged in sequence. The winding device is fixedly mounted on the lifting end of the moving adjustment device, and the winding device can be moved above the stator mounting device. The device performs a winding operation on the winding nails. The winding device is assembled with a mounting plate fixedly installed on the lifting end of the movable adjustment device. The motor and sleeve are both fixedly installed on the mounting plate, with the motor positioned above the sleeve and its rotating end facing downwards. The sleeve opening faces downwards. A slider is slidably installed on the mounting plate, positioned between the motor and the sleeve. The rotating end of the motor is threadedly connected to the slider. A connecting rod passes through the sleeve, and one end of the connecting rod is rotatably connected to the bottom of the slider. The side of the rotating block is rotatably connected to the inner wall of the sleeve, allowing the two ends of the rotating block to swing at a certain angle. This rotatable connection point is located near the side edge of the rotating block. The other end of the connecting rod is rotatably connected to the top of the rotating block. The rotating connection point of the rotating block is offset from the rotating connection point of the rotating block. The connecting rod pulls the connection point of the rotating block, causing the rotating block to rotate around the rotating connection point of the rotating block. This causes the other end of the rotating block to swing back and forth within a certain angle range. The outlet tube on the side of the rotating block is connected to the through hole on the rotating block. In use, the wire is fed into the winding device from above, passes through the through hole, and exits from the outlet tube. The stator product to be wound is placed on the stator mounting device. The moving adjustment device drives the winding device to move onto the stator. The end of the wire is clamped by the wire end fixing device. Then, the moving adjustment device drives the winding device to move up and down in the inner ring of the stator. At the same time, the stator mounting device rotates the stator, thus completing the winding process. The stator, mounted on a stator mounting device, has protruding sections at both its top and bottom. When the winding device winds the wire onto the outer surface of the stator's top, the motor rotates, pushing the slider downwards. This, in turn, pushes the connecting rod downwards, pressing one end of the rotating block, causing it to rotate clockwise. This causes the wire outlet tube on the rotating block to swing downwards, pressing the wire to the outer surface of the stator's top. The stator mounting device then rotates, completing the wire attachment on the outer surface of the stator's top. The pressing device moves above the stator, pressing down on the opening at the stator's top to prevent the wire from detaching. The adjusting device moves downwards, moving the rotating block below the stator. The motor rotates, pulling the slider upwards. The slider drives the connecting rod upwards, and the connecting rod pulls one end of the rotating block in the opposite direction around the rotating block's rotation connection point.The outlet end of the cable tube is swung to the position of being adjacent to the bottom area of ​​the stator's outer surface. The stator mounting device rotates, and the cable exits from the outlet, completing the hanging operation. After winding, the wire cutting device cuts the wire, completing the winding operation for one stator. This structural design enables the hanging of cables at both the top and bottom of the stator's outer surface. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0028] In one embodiment of this utility model, such as Figures 1-7 As shown, a stator winding mechanism is provided, including a mounting base 10, a stator mounting device 20, a wire end fixing device 30, a wire pressing device 40, a wire cutting device 50, a moving adjustment device 60, and a winding device 70. The stator mounting device 20, wire end fixing device 30, wire pressing device 40, wire cutting device 50, and moving adjustment device 60 are all mounted on the mounting base 10, and are arranged sequentially. The winding device 70 is then fixedly mounted on the lifting end of the moving adjustment device 60. The moving adjustment device 60 can move the winding device 70 above the stator mounting device 20, enabling the winding device 70 to perform winding operations on the stator fixedly mounted on the stator mounting device 20.

[0029] like Figures 1-3 As shown, the winding device 70 is assembled from a mounting plate 51, a motor 72, a slider 73, a connecting rod 74, a sleeve 75, and a rotating block 76. The mounting plate 51 is fixedly mounted on the lifting end of the movable adjustment device 60, and the mounting plate 51 is vertically arranged. The motor 72 is fixedly mounted on the side of the mounting plate 51 near the top. The slider 73 is slidably mounted on the side of the mounting plate 51, with the motor 72 located above the slider 73. The rotating end of the motor 72 is threadedly connected to the slider 73. One end of the sleeve 75 is mounted on the side of the mounting plate 51 near the bottom, and the slider 73 is located above the sleeve 75. One end of the connecting rod 74 is inserted into the sleeve 75, and the other end of the connecting rod 74 is rotatably connected to the bottom of the slider 73. One end of the sleeve 75 has an opening. The rotating block 76... The connecting rod 74 is rotatably installed at the bottom opening of the sleeve 75, and the other end of the connecting rod 74 is rotatably connected to the top of the rotating block 76. The rotatable connection point between the rotating block 76 and the inner wall of the sleeve 75 is located near one side edge of the rotating block 76, and this rotatable connection point is located at a position offset from the center to the top. The connection point between the connecting rod 74 and the rotating block 76 is located near the top edge of the rotating block 76. The rotatable connection point and the connection point of the connecting rod are located near the two side edges, so that the distance from the rotatable connection point to the two ends of the rotating block 76 is different. The connecting rod 74 drives one end of the rotating block 76 to move slightly. Through the different distances between the rotatable connection point and the two ends of the rotating block 76, the end closer to the rotatable connection point swings slightly, causing the other end of the rotating block 76 to swing more significantly.

[0030] like Figure 1 As shown, a first anti-jump wheel 621 is provided on the top of the movable adjustment device 60. The first anti-jump wheel 621 is located above the motor 72. After the wire passes through the first anti-jump wheel 621, it extends downward. The first anti-jump wheel 621 plays a certain guiding role for the wire.

[0031] like Figure 1 As shown, a tension adjustment device 622 is also provided on the top of the movable adjustment device 60. The wire passes around the adjustment end of the tension adjustment device 622 and enters the winding device. The tension adjustment device 622 adjusts the tension of the wire.

[0032] like Figures 1-3 As shown, a second anti-jump wheel 711 is also provided on the mounting plate 51. The second anti-jump wheel 711 is arranged adjacent to the sleeve 75. The wire extends downward through the second anti-jump wheel 711 and enters from one end of the through hole of the rotating block 76 and is output through the outlet tube.

[0033] like Figures 2-3 As shown, the rotating block 76 has an installation groove 761 and a guide block 762 on the wire inlet side. The installation groove 761 is connected to one end of the through hole. The guide block 762 is fixedly installed in the installation groove 761. One side of the guide block 762 is arc-shaped, and an arc-shaped guide groove is opened on the arc-shaped surface. One end of the arc-shaped guide groove extends to connect with the through hole, guiding the wire into the through hole.

[0034] like Figure 1 As shown, the movable adjustment device 60 includes a planar movable mechanism 61 and a lifting adjustment mechanism 62. The planar movable device is fixedly installed on the mounting base 10, and the lifting adjustment mechanism 62 is fixedly installed on the movable end of the planar movable mechanism 61. The mounting plate 51 is fixedly installed on the lifting end of the lifting adjustment mechanism 62. The planar movable device drives the lifting adjustment mechanism 62 to move closer to and away from the stator mounting device 20.

[0035] like Figure 1 As shown, the planar moving mechanism 61 can change its lateral and longitudinal positions on the horizontal plane, controlling the rotating block 76 of the winding device 70 to move above the stator in the stator mounting device 20.

[0036] like Figure 1 and Figure 4As shown, the stator mounting device 20 is assembled from a rotary motor 21, a mounting base 22, a first pressure plate 23, a second pressure plate 24, and two push cylinders 25. The rotary motor 21 is fixedly mounted on the bottom of the mounting base 10, with its rotating end extending upwards through the mounting base 10. The mounting base 22 is fixedly mounted on the rotating end of the rotary motor 21, and has a clearance hole and a locking interface. The clearance hole is horizontally positioned through the side of the mounting base 22, and the locking interface is located on the top of the mounting base 22, communicating with the clearance hole. A limit ring is provided on the inner wall of the locking interface, near the junction of the locking interface and the clearance hole. The inner radius of the limit ring is smaller than the inner radius of the locking interface, creating a misalignment surface between the limit ring and the locking interface. During stator assembly, the stator is locked and limited by the limit ring. A pressure plate 23 and a second pressure plate 24 are rotatably mounted on the side of the mounting base 22. Two push cylinders 25 are fixedly mounted on the top plane of the mounting base 10. One end of the first pressure plate 23 and the second pressure plate 24 extends downward. The moving ends of the two push cylinders 25 are respectively positioned towards the downward-extending ends of the first pressure plate 23 and the second pressure plate 24. The two push cylinders 25 respectively press one end of the first pressure plate 23 and the second pressure plate 24. By rotating the connection point, the other ends of the first pressure plate 23 and the second pressure plate 24 rotate in opposite directions. The other ends of the first pressure plate 23 and the second pressure plate 24 are bent and extended into the card interface. When one end of the first pressure plate 23 and the second pressure plate 24 is pressed by the push cylinders 25, the other ends of the first pressure plate 23 and the second pressure plate 24 rotate in the direction away from the card interface.

[0037] like Figure 1 and Figure 4 As shown, multiple sliding grooves are provided on the top of the mounting base 22, and the two ends of the sliding grooves pass through the outer side of the mounting base 22 and the inner side of the card interface, respectively.

A concave arc-shaped surface is provided at the bending end, and a limiting opening is provided at the bottom edge of the bending end. This limiting opening can be engaged with the edge of the stator for limiting.

[0039] like Figure 5As shown, the wire pressing device 40 is assembled from a mounting frame 41, a lifting cylinder 42, a first transverse cylinder 43, a moving plate 44, and a wire pressing plate 45. A wire pressing protrusion is provided on one edge of the wire pressing plate 45, located near the end edge. The mounting frame 41 is slidably connected to the mounting base 10. The lifting cylinder 42 is mounted on the mounting base 10, with its lifting end facing upwards. The lifting end of the lifting device is fixedly connected to the bottom of the crossbeam of the mounting frame 41. The lifting device can be a cylinder. The first transverse cylinder 43 is fixedly mounted on the mounting frame 41. The moving plate 44 is slidably connected to the mounting frame 41. One end of the wire pressing plate 45 is fixedly connected to the moving plate 44. The moving end of the first transverse cylinder 43 is fixedly connected to the moving plate 44, pushing the moving plate 44 to move laterally back and forth, causing the wire pressing protrusion on the wire pressing plate 45 to move onto the stator. The lifting device moves downwards, causing the mounting frame 41 to descend, thus pressing the wire pressing protrusion onto the wire.

[0040] like Figure 6 As shown, the wire end fixing device 30 is composed of a support frame 31, a second transverse cylinder 32, a rotary cylinder 33, a clamping cylinder 34, and a rotating rod 35. The support frame 31 is slidably mounted on the mounting base 10. The second transverse cylinder 32 is fixedly mounted on the mounting base 10, and the moving end of the second transverse cylinder 32 is fixedly connected to the support frame 31. The support frame 31 is moved. The rotary cylinder 33 is fixedly mounted on the side of the support frame 31, and the rotating end of the rotary cylinder 33 passes through the side of the support frame 31. One end of the rotating rod 35 is fixedly connected to the rotating end of the rotary cylinder 33, and the other end of the rotating rod 35 is rotatably connected to the support frame 31. The clamping cylinder 34 is fixedly mounted on the rotating rod 35. The rotary cylinder 33 drives the rotation of the rotating rod 35, which in turn drives the rotation of the clamping cylinder 34.

[0041] like Figure 5 As shown, the thread cutting device 50 is assembled from a mounting plate 51, a cutting cylinder 52, and a pneumatic shear 53. The mounting plate 51 is fixedly mounted on the mounting base 10, and the mounting plate 51 is aligned with the mounting base 22. The cutting cylinder 52 is mounted on the side of the mounting plate 51 and is inclined. The moving end of the cutting cylinder 52 is inclined downward toward the mounting base 22. The pneumatic shear 53 is fixedly mounted on the moving end of the cutting cylinder 52. An auxiliary groove is provided on the side of the cutting cylinder 52. A fixing plate is provided on the moving end of the cutting cylinder 52. One end of the fixing plate is bent at 90° and fixedly connected to the moving end of the cutting cylinder 52. The other end of the fixing plate is slidably connected to the auxiliary groove. An extension plate is mounted on the fixing plate and is fixedly connected to the pneumatic shear 53.

[0042] In use, the stator winding mechanism of this utility model involves fixing the stator in the snap-fit ​​interface on the mounting base 22. The first pressure plate 23 and the second pressure plate 24 press against the edge of the stator, and each positioning key abuts against the side of the stator for limitation. The planar moving mechanism 61 moves the winding device 70 above the stator, and the lifting and adjusting mechanism 62 lowers the height of the winding device 70, causing the rotating block 76 of the winding device 70 to move to the stator. The clamping cylinder 34 clamps the end of the wire. The rotating block 76 swings as the motor 72 drives the connecting rod 74 to move up and down, and the moving and adjusting device 60 drives the entire winding device 70 to move up and down. This, in conjunction with the rotating motor 21, rotates the mounting base 22 to change the stator position. The angle is adjusted to complete the internal winding of the stator. Clicking and pulling the connecting rod 74 upwards causes the rotating block 76 to rotate counterclockwise. The wire outlet tube on the rotating block 76 is tilted upwards to avoid the bottom edge of the stator and perform the wire hanging operation on the bottom side of the stator. Conversely, the connecting rod 74 moves downwards, the rotating block 76 rotates clockwise, and the wire outlet tube on the rotating block 76 rotates downwards to perform the wire hanging operation on the top side of the stator. The pressure plate 45 on the pressure device 40 positions the wire on the stator. After winding is completed, the air shear 53 on the wire cutting device 50 moves to cut the end of the wire. Through the above structural settings, the automatic winding of the hanging wire during the stator winding process is realized.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
