Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 3As shown, a stator flat wire feeding mechanism includes a base plate 1. A fixed seat 2 is bolted to the upper side of the base plate 1. Two guide posts 4 are symmetrically mounted on the upper side of the fixed seat 2 by bolts. A movable seat 3 is slidably connected to the two guide posts 4 on the upper side of the fixed seat 2. A horizontal plate 5 is bolted to the upper side of the two guide posts 4. A cylinder 6 is bolted to the upper side of the horizontal plate 5. The output shaft of the cylinder 6 passes through the horizontal plate 5 and is connected to the upper side of the movable seat 3. Two sets of wire feeding assemblies are symmetrically arranged on the front side of the movable seat 3 and the fixed seat 2. The wire feeding assembly includes two wire feeding wheels 12 symmetrically arranged on the left and right and three small rollers 17 arranged between the two wire feeding wheels 12. The wire feeding wheels 12 and the small rollers 17 are rotatably connected to the front side of the fixed seat 2 and the movable seat 3 by bearings. A wire feeding belt 11 is arranged on the two wire feeding wheels 12. The small rollers 17 and the wire feeding wheels 12 are all engaged with the wire feeding belt 11. A tension adjustment assembly for adjusting the tension of the wire feeding belt 11 is arranged on the movable seat 3 and the fixed seat 2.

[0021] A drive assembly for driving the wire feeding wheel 12 to rotate is provided on the base plate 1;

[0022] A deburring assembly for cleaning burrs on the surface of stator flat wires is provided on the right side of the base plate 1.

[0023] During use, the operator can use cylinder 6 to move the movable seat 3 up and down along the guide post 4, thereby adjusting the distance between the upper and lower wire feeding belts 11 to adapt to the conveying of different models of stator flat wires. At the same time, the small roller 17 increases the wire feeding force point between the wire feeding belt 11 and the stator flat wire, ensuring the stability of the stator flat wire during conveying.

[0024] In this embodiment, the tension adjustment assembly includes two cylinders 8. A cylinder mounting plate 7 is bolted to the upper side of the movable seat 3. The two cylinders 8 are located on the base plate 1 and the cylinder mounting plate 7 respectively, and the two cylinders 8 are arranged symmetrically up and down. The front sides of the movable seat 3 and the fixed seat 2 are slidably connected to the slide plate 10 through the slide rail 19. The front side of the slide plate 10 is symmetrically connected to two pressure rollers 18 through the bearing. The front side of the slide plate 10 is bolted to a cylinder connecting block 9 connected to the output shaft of the cylinder 8.

[0025] In use, the operator can push the slide plate 10 up and down along the slide rail 19 on the movable seat 3 or the fixed seat 2 by the cylinder 28. When the slide plate 10 slides, the pressure roller 18 can squeeze and push the wire feeding belt 11, thereby realizing the tension adjustment of the wire feeding belt 11 and ensuring the reliability of the wire feeding belt 11 when conveying stator flat wire.

[0026] In this embodiment, the drive assembly includes a motor mounting plate 28 and a gear mounting plate 29 bolted to the base plate 1. A motor 27 is bolted to the rear side of the motor mounting plate 28. The output shaft of the motor 27 passes through the motor mounting plate 28 and is mounted with a drive gear 26. The drive gear 26 is coaxially fixedly connected to one of the wire feeding wheels 12 on the fixed seat 2. A driven gear 25 meshing with the drive gear 26 is rotatably connected to the rear side of the fixed seat 2 via a bearing. A transmission wheel 22 is rotatably connected to the front side of the gear mounting plate 29 via a bearing. The transmission wheel 22 is fixedly connected to the driven gear 25. A transmission wheel 23 is rotatably connected to the rear side of the movable seat 3 via a bearing. The axis of the transmission wheel 23 extends to the other side of the movable seat 3 and is coaxially fixedly connected to one of the wire feeding wheels 12. An adaptive component is provided on the rear side of the movable seat 3. A transmission wheel 24 is provided on the adaptive component. A transmission belt 21 is provided between the transmission wheel 22, the transmission wheel 23, and the transmission wheel 24 for transmission.

[0027] In use, motor 27 drives drive gear 26 to rotate, and drive gear 26 drives driven gear 25 to rotate. Under the action of drive belt 21, drive wheel 1 22, drive wheel 23 and drive wheel 3 24 rotate synchronously with driven gear 25, thereby realizing synchronous reverse rotation of wire feeding belt 11 on movable seat 3 and fixed seat 2, ensuring the reliability of the two wire feeding belts 11 when conveying stator flat wire. When movable seat 3 moves up and down, drive wheel 3 24 can adjust the distance between drive wheel 3 24 and drive wheel 2 23 through adaptive component to prevent drive belt 21 from being too loose or too tight, thus ensuring the stability of drive belt 21 during use.

[0028] In this embodiment, the adaptive component includes a slider 20 that is slidably connected to the rear side of the movable seat 3 via a slide rail 19. A transmission three is rotatably connected to the rear side of the slider 20 via a bearing. A vertical plate 31 is bolted to the rear side of the fixed seat 2. The upper end of the vertical plate 31 is provided with an inclined surface that slopes upward from left to right. A cam follower 32 that cooperates with the inclined surface of the vertical plate 31 is bolted to the right side of the slider 20.

[0029] When the movable seat 3 moves upward, the transmission belt 21 will be overstretched. At this time, the slider 20 will be pulled by the transmission belt 21 and move towards the direction of the transmission wheel 23. During the movement of the slider 20, the inclined surface at the upper end of the vertical plate 31 and the cam follower 32 can cooperate to guide the sliding direction, thereby ensuring the tension of the transmission belt 21 and preventing it from being overstretched.

[0030] In this embodiment, the deburring assembly includes a fixed frame 13 located on the right side of the fixed base 2. Two brush wheels 15 are symmetrically connected to the fixed frame 13 via bearings. Two brushless motors 30 are bolted to the rear side of the fixed frame 13. The output shafts of the two brushless motors 30 are coaxially fixedly connected to the two brush wheels 15. Two through-holes 14 are symmetrically arranged on the left and right sides of the fixed frame 13. In use, the stator flat wire passes through the two through-holes 14 and is inserted into the fixed frame 13. At the same time, the two brush wheels 15 can rotate under the drive of the brushless motors 30, thereby brushing the surface of the stator flat wire in the fixed frame 13 and removing the burrs on the surface of the stator flat wire.

[0031] In this embodiment, a discharge pipe 16 communicating with the inner side of the fixed frame 13 is integrally formed on the lower side of the fixed frame 13. When in use, impurities in the fixed frame 13 can be discharged along the discharge pipe 16 under the action of gravity, preventing impurities from accumulating in the fixed frame 13. At the same time, it improves the convenience for workers to clean the fixed frame 13.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
