[0032] Reference Figure 1-Figure 3 A double-station three-needle winding machine provided in an embodiment of the present application includes a frame 10, a fixture 20 provided on the frame 10 for clamping a double stator, and two winding mechanisms provided on the frame 10 for winding the double stators, each winding mechanism includes a winding device 30 with a three-needle rod, a translation device 40 provided on the frame 10 for driving the winding device 30 to move horizontally, and a lifting device 50 provided on the frame 10 for driving the winding device 30 to move up and down. The lifting devices 50 of the two winding mechanisms are independently arranged, and the two winding devices 30 are staggered and moved up and down under the drive of each lifting device 50.

[0033] In this embodiment, the two stators are wound using independent winding mechanisms respectively, and the two winding devices 30 are staggered and moved up and down under the drive of their respective lifting devices 50, so that the balance of the entire frame 10 is better and the shock absorption effect is good. In addition, the three needle bars are used to wind the two stators at the same time, and the winding efficiency is greatly improved.

[0034] Specifically, refer to Figure 3 and Figure 4 The lifting device 50 includes a servo motor 51 and a pulley transmission structure driven by the servo motor 51, and the pulley transmission structure is connected to the winding device 30. The pulley transmission structure is adopted, and the pulley transmission stability is better and the vibration is reduced.

[0035] Specifically, a support frame 11 is provided at the bottom of the frame 10, and a servo motor 51 is horizontally arranged on the upper part and at the rear of the support frame 11. The pulley transmission structure includes a driving wheel 52, a driven wheel 53, a synchronous belt (not shown in the figure), a first slider 54 and two first slide rails 55. Among them, the driving wheel 52 and the driven wheel 53 are arranged in parallel up and down, the driving wheel 52 is located at the top and connected to the output shaft of the servo motor 51, and the synchronous belt connects the driving wheel 52 and the driven wheel 53. The first slider 54 is connected to the synchronous belt, and the first slider 54 is also arranged on the two first slide rails 55. The two first slide rails 55 are arranged along the vertical direction of the support frame 11 and are arranged close to the front side. A push rod 56 is provided on the first slider 54, and the push rod 56 extends from the bottom of the frame 10 to the top of the frame 10, and the winding device 30 is arranged on the top of the push rod 56. When the output shaft of the servo motor 51 rotates, the synchronous belt is driven to rotate, and the synchronous belt drives the first slider 54 to move along the first slide rail 55, thereby driving the push rod 56 and the winding device 30 located on the push rod 56 to move up and down.

[0036] Furthermore, in this embodiment, there are two push rods 56, which are respectively located at the two ends of the first slider 54. A connecting block (not shown in the figure) is fixed in the middle of the first slider 54, and the connecting block extends into the support frame 11 and is fixedly connected to the synchronous belt. By providing two push rods 56, the winding device 30 is better supported and the support is more balanced.

[0037] Furthermore, a vertical guide sliding structure 60 is also provided on the translation device 40 above the frame 10, and the winding device 30 is fixedly connected to the vertical guide sliding structure 60. On the one hand, the winding device 30 is fixedly connected to the top rod 56, and while moving up and down under the action of the top rod 56, it slides along the vertical guide sliding structure 60, and the vertical guide sliding structure 60 also plays a good guiding and limiting role, so that the vertical movement of the winding device 30 in the vertical direction is more accurate and more stable. At the same time, since the vertical guide sliding structure 60 is provided on the translation device 40, when the translation device 40 moves horizontally, it also drives the vertical guide sliding structure 60 and the winding device 30 to move horizontally.

[0038] Specifically, refer to Figure 4 and Figure 5The winding device 30 includes a bottom plate 31, a needle bar assembly disposed on the bottom plate 31, and a connecting plate 32 disposed horizontally on the needle bar assembly. The connecting plate 32 is fixedly connected to the vertical guide sliding structure 60, and a sliding structure is provided between the connecting plate 32 and the needle bar assembly. By providing a sliding structure between the connecting plate 32 and the needle bar assembly, the up and down movement of the needle bar assembly under the action of the top rod 56 does not conflict with the horizontal movement in the horizontal direction. When moving in the horizontal direction, one coil is wound forward and backward, and when moving in the up and down direction, multiple coils are wound along the depth direction of the winding groove.

[0039] Specifically, the needle bar assembly includes a second slider 33 disposed in the middle of the bottom plate 31, a third slider 34 and a fourth slider 35 respectively disposed on both sides of the second slider 33, and a first needle bar 36, a second needle bar 37 and a third needle bar 38 respectively disposed at the front ends of the second slider 33, the third slider 34 and the fourth slider 35. The third slider 34 and the fourth slider 35 are symmetrically and tiltedly disposed with the second slider 33 as the center, and the connecting plate 32 is fixedly connected to the second slider 33. The sliding structure includes pins 39 respectively disposed on the third slider 34 and the fourth slider 35, and pin holes 321 disposed on the connecting plate 32 for each pin 39 to pass through. Each pin hole 321 is in the shape of a long strip and tiltedly disposed along the length direction of the connecting plate 32. Since the connecting plate 32 is fixedly connected to the vertical guide sliding structure 60, when the translation device 40 drives the vertical guide sliding structure 60 to move horizontally, the connecting plate 32 is also driven to move horizontally. Since the second slider 33 is set in the same direction as the translation device 40, not tilted, and the second slider 33 is fixedly connected to the connecting plate 32, the connecting plate 32 drives the second slider 33 to move horizontally when it moves horizontally. Since the second slider 33 and the third slider 34 are relatively tilted, the pin shaft 39 is limited by the pin hole 321 on the connecting plate 32, so that when the second slider 33 and the third slider 34 move horizontally, the pin shaft 39 slides relatively in the pin hole 321, thereby avoiding horizontal interference.

[0040] In this embodiment, since the needle bar assembly has three needle bars, when winding a stator, the three needle bars can simultaneously wind the three adjacent winding grooves on the stator. After the winding of the three winding grooves is completed, the stator rotates a certain angle, and the three needle bars simultaneously wind the other three winding grooves. During winding, the lifting device 50 and the translation device 40 move in the vertical direction and the horizontal direction respectively, so that the needle bars perform track-shaped circle winding.

[0041] Furthermore, in order to make the third slider 34 and the fourth slider 35 move horizontally more smoothly and more steadily, in this embodiment, second slide rails 311 are respectively provided on the bottom plate 31 and at the bottom of the third slider 34 and the fourth slider 35. The third slider 34 and the fourth slider 35 are respectively provided on the second slide rails 311 and slide on the second slide rails 311.

[0042] In this embodiment, the vertical guide sliding structure 60 includes a column 61, two third slide rails 62 arranged along the column 61, and a fifth slide block 63 sliding on each third slide rail 62, each fifth slide block 63 is respectively provided with a fixing plate 64, and each fixing plate 64 is provided with a positioning hole 65 at the end thereof, and a positioning pin (not shown in the figure) that can be inserted into each positioning hole 65 is provided at the bottom of the connecting plate 32. The fixed connection between the positioning pin and the positioning hole 65 realizes the fixed connection between the connecting plate 32 and the vertical guide sliding structure 60.

[0043] Similarly, in order to ensure that the connecting plate 32 slides smoothly and stably on the bottom plate 31 , a plurality of fourth slide rails 312 are provided on the bottom plate 31 , and sixth slide blocks 322 are provided at the bottom of both ends of the connecting plate 32 , and the sixth slide blocks 322 are slidably disposed on the fourth slide rails 312 .

[0044] In summary, in the embodiment of the present application, the winding device 30 with three needle bars is used to wind the double stators separately, and the winding device 30 moves staggered up and down, which has a good shock absorption effect, makes the equipment more stable, and has high production efficiency.

[0045] The above description is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
