[0002] During the production process, copper wire needs to be wound into coils to form the stator winding. In the early days, the winding was done by hand, which was extremely inefficient, had poor consistency, could not meet the needs of mass production, and could not control the quality and size.

[0003] Some systems use winding equipment to improve operational efficiency. However, due to unreasonable structural design, motor and tension settings, as well as improper winding and splitting processes, copper wires may accumulate on the winding board, resulting in poor winding and damaged wires, which affects the automated operation of the equipment.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the above-mentioned mechanism and component settings, the stator winding equipment of this motor can use a high-speed rotating flywheel to orderly wind and arrange copper wire with a certain tension on the winding plate to form a coil. The clamping components work together to act on the copper wire, and finally the output copper wire meets the winding process and drawing size requirements. By adjusting the movement, start / end position and copper wire tension of each mechanism and component, the winding process of copper wire with different diameters can be realized, and the produced coils have high consistency and good tightness. 2. The tension control mechanism can adjust and control the tension of the copper wire to prevent loose feeding and tangling; the flywheel mechanism and the wire separating mechanism work together to produce high-quality wound coils according to requirements; 3. The flywheel mechanism can not only use its hollow rotating spindle assembly to drive the rotating flywheel to rotate at high speed and wind the copper wire onto the winding plate according to a certain pattern, but also use its push-pull shaft assembly to control the push plate and the winding plate, allowing them to move relative to each other to advance the copper wire wound on the winding plate forward according to the winding rules; at the same time, it can also utilize the... The wire threading assembly mounted on the flywheel assembly pulls the copper wire from the direction of the tension control mechanism onto the rotating flywheel, and guides and limits the copper wire, allowing it to be neatly wound around the winding plate; 4. Integrating the hollow rotating spindle assembly, the flywheel assembly, the wire threading assembly, the winding assembly, and the push-pull shaft assembly together on the same flywheel mechanism makes its structure more compact and facilitates the linkage operation of flywheel winding, allowing wire threading, winding, and pushing to be completed in a shorter time; 5. The wire separating mechanism can move in a coordinated manner through its multiple gripper assemblies. After completing the copper wire sorting operation, the previously wound copper wire is moved out of the winding position. With the help of the winding plate, continuous forming of copper wire can be achieved, and the forming of the next copper wire is not affected during continuous winding. 6. The coil clamping assembly arranged below the wire sorting mechanism can prevent the copper wire generated during winding from forming a bulge shape, which would cause problems such as crossing during the forming of connecting wires or crossing during manual wire laying. By pre-pressing the copper wire with the coil clamping assembly, the width of the coil is made to meet the size required by the drawing, ensuring that the width of the copper wire is close to that of the winding plate, and avoiding the copper wire bulging and crossing.

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] Example 1: A motor stator winding device is provided, such as... Figures 1 to 20 As shown, the device includes a platform 1. From one side to the other, a tension control mechanism 4, a flywheel mechanism 5, a wire splitting mechanism 6, and a wire feeding mechanism 7 are arranged sequentially on the platform 1. The copper wire fed in is pulled to the flywheel mechanism 5 via the tension control mechanism 4. The flywheel mechanism 5 includes a movable first support 8 mounted on the platform 1. A rotatable hollow rotating spindle assembly is mounted on the first support 8. One end of the hollow rotating spindle assembly is connected to the flywheel assembly. A wire threading assembly is mounted on the flywheel assembly. An axially movable push-pull shaft assembly 20 is also provided inside the hollow rotating spindle assembly. One end of the push-pull shaft assembly 20 extends from the hollow rotating spindle assembly and is connected to a wire pusher plate 23. The first support 8 also has a connection to the flywheel... The winding assembly is coaxially arranged with a winding plate 22 extending towards the wire splitting mechanism. A pusher plate 23 is sleeved on the winding plate 22. The wire splitting mechanism 6 includes a movable second bracket 9 mounted on the equipment platform 1. The second bracket 9 has a process through hole 901 in the middle. A movable wire cutting assembly 28 is provided above the process through hole 901, and a movable coil clamping assembly 29 is provided below it. The coil clamping assembly 29 acts on both sides of the winding plate 22. Multiple clamping claw assemblies are provided on both sides of the process through hole 901. The multiple clamping claw assemblies are used for moving and splitting copper wires on the winding plate 22. The wire feeding mechanism 7 extends outward from the end of the winding plate 22 through the process through hole 901.

[0020] This motor stator winding equipment, through the aforementioned mechanisms and components, utilizes a high-speed rotating flywheel to orderly wind copper wire with a certain tension onto a winding plate to form a coil. The clamping components work together to apply pressure to the copper wire, ultimately ensuring the output copper wire meets the winding process and drawing dimensional requirements. By adjusting the movement, starting / ending positions, and copper wire tension of each mechanism and component, winding processes for copper wires of different diameters can be achieved, resulting in coils with high consistency and tightness.

[0021] The tension control mechanism 4 can adjust and control the tension of the copper wire, that is, its tightness, to prevent it from being loosely transported and tangled; the flywheel mechanism 5 and the wire separating mechanism 6 are key mechanisms for winding, and the two work together to produce high-quality wound coils according to requirements; the wire feeding mechanism 7 can transport the completed wound coil products out completely.

[0022] The flywheel mechanism 5 can not only drive the rotating flywheel to rotate at high speed using the hollow rotating spindle assembly mounted on it, so that the copper wire is wound on the winding plate 22 in a certain pattern, but also control the push plate 23 and the winding plate 22 using the push-pull shaft assembly mounted on it, so that the two move relative to each other, so as to push the copper wire wound on the winding plate 22 forward according to the winding rules, such as pushing it one step upward for each turn; at the same time, the wire threading assembly 18 mounted on the flywheel assembly can also be used to pull the copper wire from the direction of the tension control mechanism to the rotating flywheel, and guide and limit the copper wire, so that it is neatly wound on the winding plate.

[0023] Integrating the hollow rotating spindle assembly, the flywheel assembly, the threading assembly, the winding assembly, and the push-pull shaft assembly onto the same flywheel mechanism facilitates the coordinated operation of the flywheel winding and makes the structure more compact. This allows threading, winding, and pushing to be completed in a shorter time, and the separation mechanism quickly completes the separation and sorting of several copper wires.

[0024] The wire splitting mechanism 6, through its multiple gripper components, can coordinate and move to complete the wire splitting and sorting operation (gripping or releasing the copper wire), move the previously wound copper wire out of the winding position, and with the help of the winding plate, can achieve continuous forming of copper wire, and the forming of the next copper wire is not affected during continuous winding.

[0025] The coil clamping assembly 29 arranged below the wire splitting mechanism 6 can prevent the copper wire generated during winding from being bulging (small at both ends and large in the middle), which would cause problems such as crossing during the forming of connecting wires or crossing during manual wire laying. By pre-pressing the copper wire with the coil clamping assembly 29, the width of the coil is made to meet the size required by the drawing, ensuring that the width of the copper wire is close to that of the winding plate, thus avoiding the situation of copper wire bulging and crossing.

[0026] The wire-cutting assembly arranged below the wire-splitting mechanism can perform wire-cutting operations. When the first and last wires are wound, they are connected to the wire-cutting assembly. When the first and last wires move synchronously with the coil towards the feed port, the copper wire can be cut to form the first and last lead wires.

[0027] The first bracket 8 and the second bracket 9 are respectively installed on the equipment platform 1 through a multi-rail slider mechanism. In addition to supporting the flywheel mechanism 5 and the branching mechanism 6, they can also move in the conveying direction to adjust the position of the flywheel mechanism 5 and the branching mechanism 6 as a whole.

[0028] Furthermore, such as Figure 2 As shown, an oil removal component 3 is also provided upstream of the tension control mechanism 4. The oil removal component 3 includes a support rod 2 disposed outside the equipment. A rotatable wheel 301 is provided on the support rod 2. A felt 302 is provided on the outer periphery of the wheel 301. A copper wire is connected to the tension control mechanism 4 via the felt 302.

[0029] By setting the degreasing component 3, the felt 302 can remove oil and other impurities from the surface of the copper wire before it is conveyed into the equipment, which is beneficial to the subsequent winding and forming of the copper wire. The support rod 2 is set outside the equipment frame to support the wheel 301 externally. The wheel 301 can rotate passively. When a copper wire passes by, it will rotate synchronously. During the rotation, the felt 302 will adhere the impurities on the copper wire. The adhered impurities will not enter the equipment frame, ensuring the cleanliness of the equipment frame.

[0030] For this device, the device platform is equipped with the aforementioned device frame, which is completely covered with transparent glass (with an openable and closable door), which can isolate the external environment, reduce pollution, thus avoiding affecting the winding accuracy, and also facilitate the observation of the winding situation.

[0031] Furthermore, such as Figure 3 As shown, the tension control mechanism 4 includes a tension motor mounting plate 401 disposed on the internal support frame of the equipment. A tension motor 402 is mounted on the tension motor mounting plate 401, and a tension wheel 403 is connected to the output end of the tension motor 402. The tension motor 402 drives the tension wheel 403 to rotate, thereby adjusting the tension of the copper wire wound around the tension wheel 403.

[0032] To ensure the copper wires are neatly arranged and to define the characteristic parameters required for the winding process, the tension of the copper wires during winding needs to be adjusted. The tension control mechanism 4 has a tension adjustment range of 0-100N; it also has a pre-straightening function for the supplied copper wires. Considering the inconsistent lengths of the copper wires wound by the rotating flywheel (a pattern of 2-3-1-2-3-1), the servo motor is equipped with acceleration / deceleration characteristics and actively feeds the wire during winding to maintain a relatively stable tension and prevent the copper wires from being forcibly stretched and failing during winding.

[0033] Furthermore, in combination Figures 4-7 As shown, the first support 8 is provided with a first bearing support 14. The hollow rotating spindle assembly includes a hollow spindle 11 connected to the first bearing support 14. One end of the hollow spindle 11 is connected to a first servo motor 13 through a first transmission component 12. The first servo motor 13 is mounted on the first support 8. The other end of the hollow spindle 11 is connected to the flywheel assembly. The flywheel assembly includes a rotating disk 15 connected to the hollow spindle 11. The end face of the rotating disk 15 is connected to a rhomboid rotating flywheel 17 through several connecting rods 16. One end of the rotating flywheel 17 is provided with the threading component 18, and the other end is provided with a counterweight 19.

[0034] The first bearing support 14 supports the hollow spindle 11, which can rotate under the drive of the first transmission component 12 and the first servo motor 13, thereby driving the rotating flywheel 17 connected in front via a rotating disk and connecting rods to rotate. The rotating flywheel 17 is connected to the rotating disk 15 and multiple connecting rods 16, which not only stably drives the large-sized flywheel to rotate smoothly, but also leaves the middle space empty for connecting and arranging other components.

[0035] The threading assembly 18 and the counterweight 19 are respectively placed at the vertices of the two long diagonals of the rhomboid rotating flywheel, which facilitates threading, guiding and winding operations, and also plays a balancing role, making the winding more stable and preventing obvious fluctuations.

[0036] like Figure 9 and Figure 10 As shown, the threading assembly 18 includes a threading cylinder 1801 disposed at the end of the rotating flywheel 17. The threading cylinder 1801 has a threading channel 1802 inside. The two ends of the threading cylinder 1801 are respectively provided with a first guide wheel 1803 and a second guide wheel 1804. After the copper wire fed from the tension control mechanism passes through the first guide wheel 1803, the threading channel 1802 and the second guide wheel 1804, the copper wire can be reversed, and the copper wire pulled at an angle can be converted into a vertically output copper wire so that it can be wound vertically during rotation. A threading base plate 1805 is also provided below the end of the threading cylinder 1801. The threading base plate 1805 has a threading hole 1806. The copper wire adjusted to be vertical is pulled towards the central axis through the threading hole 1806. This can further limit and guide the pulling direction of the copper wire, and reduce the shaking and fluctuation of the copper wire.

[0037] Furthermore, in combination Figure 8As shown, the push-pull shaft assembly 20 includes a push-pull shaft 2001 that is sleeved and connected to the hollow rotating spindle assembly and is movable. Both ends of the push-pull shaft 2001 extend from the hollow rotating spindle assembly. One end is connected to the push-wire plate through a connector, and the other end is connected to the first bracket 8 through a second bearing support 2002. A third bearing support 2003 is also provided on the push-pull shaft 2001 near the second bearing support 2002. A push-pull connecting plate 2004 is provided below the third bearing support 2003. A toothed plate 2005 is provided below the push-pull connecting plate 2004. A second servo motor 2006 is provided on the first bracket 8. The output end of the second servo motor 2006 is connected to the toothed plate 2005 and the push-pull connecting plate 2004 through a reciprocating transmission belt 2007.

[0038] The push-pull shaft 2001 can be inserted inside the hollow main shaft, which utilizes the internal space of the hollow main shaft and allows it to move axially within the hollow main shaft; the second bearing support 2002 and the third bearing support 2003 can provide a special support structure that can support the push-pull shaft without affecting its axial movement.

[0039] The connection structures of the second bearing support 2002 and the third bearing support 2003 are basically the same. Although both are connected to the first bracket 8, they can both move relative to the first bracket 8. A push-pull connecting plate 2004 is connected above the second bearing support 2002 and below the third bearing support 2003, respectively. The push-pull connecting plate 2004 is connected to the first bracket 8 through a bracket connecting plate 2008. The bracket connecting plate 2008 is fixed to the first bracket 8 by bolts. The push-pull connecting plate 2004 is provided with a sliding groove, and the bracket connecting plate 2008 is provided with a sliding groove connecting key. The sliding groove connecting key is connected in the sliding groove, so that the upper and lower bracket connecting plates 2008 and the push-pull connecting plate 2004 can be slidably connected, respectively. Since the second bearing support 2002 and the third bearing support 2003 adopt a similar centrally symmetrical arrangement, a connection relationship can be established from both the upper and lower directions. Moreover, since both bearing supports are connected to the push-pull shaft at the same time, their stability is also good.

[0040] By setting the toothed plate 2005 below the push-pull connecting plate of the third bearing support 2003 and connecting it to the reciprocating transmission belt 2007, the reciprocating motion of the toothed plate can be realized by the drive of the second servo motor 2006, that is, the axial reciprocating movement of the push-pull connecting plate 2004 and the push-pull shaft 2001, thereby pushing the winding plate and push plate connected at its front end to move relative to each other to complete the push-wire operation.

[0041] Furthermore, the winding plate 22 is provided with a high side step 2201 and a low side step 2202 along the winding direction. Figure 21 As shown), the push plate 23 is sleeved on the high side step 2201, pushing the coil wound on the high side step 2201 to the low side step. The desired coil shape can be formed by the cooperation of the high side step 2201 and the low side step 2202.

[0042] Furthermore, such as Figure 11-16 As shown, the gripper assembly includes at least a first gripper assembly 24 and a second gripper assembly 25 located on both sides of the winding plate 22, a third gripper assembly 26 arranged obliquely above the first gripper assembly 24, and a fourth gripper assembly 27 located below the second gripper assembly 25. Each gripper assembly is provided with a first mounting base 30 connected to the second bracket 9. The first mounting base 30 is provided with a first mounting plate 31 that can move in the axial direction. The first mounting plate 31 is provided with a gripper cylinder 32. The gripper cylinders of the first gripper assembly 24, the second gripper assembly 25, and the third gripper assembly 26 are respectively equipped with wire clamping claws 33. The gripper cylinder of the fourth gripper assembly 27 is equipped with a wire pushing claw 34.

[0043] These grippers can perform different line-separating functions depending on their positions. The first gripper assembly 24, the second gripper assembly 25, and the third gripper assembly 26 have the same component structure and gripper structure, but their positions are different. Through their coordinated operation, continuous forming of copper wire can be achieved. The fourth gripper assembly 27 can perform wire-pushing operations.

[0044] Multiple first mounting bases 30 can respectively mount these gripper assemblies on the second bracket 9. Each first mounting base 30 is provided with a moving mechanism (slide rail, lead screw servo drive, etc.) parallel to the central axis, which can drive the first mounting plate 31 to move along the central axis, that is, drive the gripper cylinder 32 to move. Its gripper cylinder can control the wire clamping jaws to clamp or release the copper wire in another direction. The fourth gripper assembly does not have a gripper, but a wire pusher, which can approach and move away from the coil.

[0045] Furthermore, in combination Figure 19 As shown, the coil clamping assembly 29 includes a second mounting base 2901 disposed on the second bracket 9. The second mounting base 2901 is provided with a second mounting plate 2902 that can move axially. The second mounting plate 2902 is provided with an upwardly arranged coil clamping cylinder 2903. The coil clamping cylinder 2903 is equipped with a pair of clamping arms 2904. The clamping arms 2904 are respectively connected to coil clamping plates 2905 located on the side of the winding plate 22.

[0046] The second mounting plate 2902 can also be moved on the second mounting base to adjust the position of its coil clamping cylinder, that is, to adjust the position of a pair of clamping arms 2904 and a pair of coil clamping plates 2905, so that the pair of coil clamping plates 2905 can pre-press the copper wire on both sides of the winding plate to prevent the copper wire from bulging or crossing during winding, ensuring that the coil width accurately meets the design requirements of the drawing, and ensuring that the copper wire width is close to and close to the winding plate to avoid the copper wire crossing.

[0047] Furthermore, in combination Figure 17 and Figure 18 As shown, the wire cutting assembly 28 includes a third mounting base 2801 disposed on the second bracket 9. The third mounting base 2801 is provided with a third mounting plate 2802 that can move axially. A shearing cylinder 2803 is disposed below the third mounting plate 2802. The output end of the shearing cylinder 2803 is provided with a pair of shearing arms 2804 that move vertically relative to each other. The end of one shearing arm 2804 is provided with a shearing blade 2805, and the end of the other shearing arm is provided with a shearing blade 2806. A blowing pipe 2807 is provided at the shearing blade 2806.

[0048] Similarly, the third mounting plate 2802 can also move relative to the third mounting base 2801 under the drive of the moving mechanism, thereby adjusting the position of the shearing cylinder 2803 and allowing the shearing blade 2805 and the shearing edge 2806 to move to the accurate position to cut the copper wire. The pair of shearing arms 2804 can move up and down relative to each other, so that the shearing edge 2806 can move relative to the shearing blade 2805 to cut the copper wire smoothly. The blow pipe 2807 is set at the shearing edge to blow out the copper wire waste during cutting, so as to prevent the copper wire waste from adhering to the blade and the cutting edge and affecting the next cutting. At the same time, it can also prevent the copper wire waste from falling directly onto the winding structure below.

[0049] When the first and last wires are wound, the copper wire is hung on the shearing blade. At this time, the shearing blade is in a closed state. The first and last wires move towards the feed port synchronously with the coil. For example, when the 12th set of wires is wound, the shearing blade opens, the first and last wires slide into the blade, the shearing blade moves, and cuts the copper wire to form the first and last lead wires.

[0050] Furthermore, such as Figure 20As shown, the wire feeding mechanism 7 includes a fourth mounting base 35 extending outward from the equipment platform 1. The fourth mounting base 35 is provided with a wire feeding linear module 36, and the wire feeding linear module 36 is provided with a wire feeding cylinder 37. The output end of the wire feeding cylinder 37 is connected to a wire feeding rod 38. The equipment platform 1 is also provided with a wire feeding guide groove 39 near the fourth mounting base 35. The end of the winding plate 22 is located in the wire feeding guide groove 39, and the other end of the wire feeding guide groove 39 extends to the tray 10 outside the equipment platform.

[0051] The fourth mounting base 35 is arranged along the conveying direction, and the wire feeding linear module 36 mounted on it can drive the wire feeding cylinder 37 to move along the conveying direction. During the movement of the wire feeding cylinder 37, the wire feeding rod 38 at its end can extend above the wire feeding guide groove 39, conveying the pre-formed coil inside it along the wire feeding guide groove towards the tray. The wire feeding guide groove 39 serves as a guide and limiter, and provides a stable channel for the movement of the coil; the wire feeding rod can push the coil to move; in some embodiments, the wire feeding guide groove can also be inclined, allowing the coil to slide onto the tray by itself.

[0052] Example 2: This example uses a certain coil as an example to further illustrate the operation process of the flywheel mechanism winding and the wire splitting mechanism splitting in Example 1.

[0053] like Figure 21 and Figure 22 As shown in the diagram, copper wire 1 is the connecting wire inside each coil, and copper wire 2 is the starting wire of the coil.

[0054] Step 1: The rotating flywheel winds the copper wire around the high edge step of the winding plate to form a connecting coil 1; Step 2: The pusher plate pushes the connecting wire 1 onto the low side step of the winding plate; Step 3: As the pusher plate moves backward, the rotating flywheel is limited by the pusher plate and winds the copper wire around the low side step of the winding plate to form coil 2; Step 4: The pusher plate moves backward, and at the same time the rotating flywheel is limited by the pusher plate to wind the copper wire around the low side step to form coil 3; Step 5: The pusher plate returns to its original position and reciprocates multiple times (e.g., 15 times) to complete one cycle.

[0055] When the rotating flywheel is wound to form coil 3 at end B, the pusher plate must cover the high side. After the pusher plate passes over the high side step of the winding plate, coil 3 is wound on the low side step. Otherwise, it may contact the high side end and damage the wire (loose spindle belt may cause the winding plate angle to change, causing coil 3 to contact the high side).

[0056] The process of dividing lines is combined with Figure 11 and Figure 13 As shown, the X direction is the direction of the central axis (conveying direction), and the Y direction is the horizontal direction perpendicular to the central axis.

[0057] The third gripper assembly: The horizontal X-direction reciprocating motion of the gripper is driven by the motor mounted on it, thereby moving the connecting wire from a point on the right to a point on the left. The Y-direction movement of the wire-clamping gripper of the third gripper assembly is to clamp or release the copper wire, which is executed by the motor mounted on it. First gripper assembly: With the position of the second gripper assembly unchanged, the wire gripper of the first gripper assembly is driven by a motor to move in the X direction, and the connecting wire is formed with the help of a winding plate; Second gripper assembly: When the connecting wire is being formed, the motor on the third gripper assembly enables the gripper to reciprocate in the X direction to grip or release the copper wire. Fourth gripper assembly: After the connecting wire is formed, in order to continue winding without affecting the formation of the next copper wire, the previous copper wire needs to be moved out of this winding station to make room. The pusher of the fourth gripper assembly moves in the Y direction to control its forward (pushing wire in the X direction) or backward (leaving the coil). During the wire advance, the wire clamping jaws of the third gripper assembly and the wire pushing jaws of the fourth gripper assembly operate synchronously. During the wire forming process, the first gripper assembly and the second gripper assembly operate synchronously.

[0058] The copper wire routing pattern on the winding board is 1-2-3-4-5-6 (top 1 / 3 / 5, bottom 2 / 4 / 6). However, after manual wiring to embed the copper wires into the comb, the arrangement order of the copper wires becomes 1-3-5-2-4-6. That is, the minimum width of the winding board at end A is twice the diameter of the copper wire, while the minimum width of the winding board at end B is once the diameter of the copper wire.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
