[0034] Please refer to Figures 1 - 6 , the present utility model provides a technical solution: a device for automatically cutting the wires of a brushless motor stator coil, including a support base 1, a vertical plate 2 fixedly connected to the upper surface of the support base 1, a positioning component installed on the upper surface of the support base 1. The positioning component includes a positioning tooling 6, a stator 7 is placed on the upper surface of the positioning tooling 6, the stator 7 is connected to a coil 21, and the positioning component is used for positioning the stator 7. An adjusting component is arranged inside the vertical plate 2. The adjusting component includes a driving cylinder 9 and a telescopic shaft 11. The lower end of the driving cylinder 9 is fixedly connected to a mounting seat 10, and a wire cutting component and a guiding component are connected to the lower surface of the mounting seat 10.

[0035] A support plate 16 is fixedly connected to one side of the vertical plate 2, and a material receiving component is connected to the upper surface of the support plate 16. The material receiving component is used for collecting the waste coil 21.

[0036] It is worth mentioning that when cutting the wire of the coil 21 connected to the stator 7 of the brushless motor, first, the stator 7 can be placed on the positioning tooling 6, and the stator 7 is fixed by the positioning tooling 6. Then, the positioning component transports the stator 7 above the positioning tooling 6 to the designated position. Next, the adjusting component drives the wire cutting component and the guiding component to descend. The coil 21 is guided and fixed by the guiding component, the wire of the coil 21 is cut by the wire cutting component, and the waste coil 21 cut off can be collected by the material receiving component. By performing the wire cutting operation at an extremely fast speed, it is beneficial to greatly improve the production efficiency.

[0037] Please refer to Figures 1 - 3 , a positioning cylinder 3 is fixedly installed on the upper surface of the support base 1. One end of the positioning cylinder 3 is connected to a sliding table 4. A first guide rail 5 is arranged on the upper surface of the support base 1. The sliding table 4 is slidably connected to the first guide rail 5. The positioning tooling 6 is located on the upper surface of the sliding table 4. A rotating component is connected to the lower surface of the sliding table 4. The rotating component is used to drive the stator 7 to rotate. The rotating component includes a servo motor 8. The upper end of the servo motor 8 is fixedly connected to the positioning tooling 6. The positioning tooling 6 is rotatably connected to the sliding table 4.

[0038] It should be noted that after the stator 7 is placed on the positioning tooling 6 and fixed by the positioning tooling 6, the positioning cylinder 3 pushes the sliding table 4 to move, so that the sliding table 4 slides on the upper surface of the first guide rail 5, and the first guide rail 5 guides the movement of the sliding table 4, so that the sliding table 4 drives the stator 7 to be transported to the designated position through the positioning tooling 6, which is convenient for the subsequent guiding component and wire cutting component to guide and fix and cut the wire of the coil 21. And after one cutting is completed, the servo motor 8 can drive the stator 7 to rotate through the positioning tooling 6, so that the coil 21 connected to the stator 7 rotates to a suitable position for the next wire cutting operation.

[0039] Please refer to Figures 1 - 5 , a driving cylinder 9 is fixedly installed on the upper surface of the vertical plate 2. One end of the telescopic shaft 11 is fixedly connected to the vertical plate 2, and the other end of the telescopic shaft 11 is fixedly connected to the mounting seat 10. The wire cutting component includes a wire cutting cylinder 12 and a cutting jaw 13. The wire cutting cylinder 12 is fixedly connected to the mounting seat 10. The cutting jaws 13 are symmetrically distributed about the longitudinal center line of the wire cutting cylinder 12. The guiding component includes a guiding cylinder 14 and guiding jaws 15. The guiding cylinder 14 is fixedly connected to the mounting seat 10. Two groups of guiding jaws 15 are provided.

[0040] The principle of being able to align and fix the coil 21 and cut the wire is as follows: After the slide table 4 drives the stator 7 to the designated position through the positioning tooling 6, the driving cylinder 9 pushes the mounting seat 10 to move, causing the mounting seat 10 to descend, thereby adjusting the positions of the wire cutting assembly and the alignment assembly connected to the mounting seat 10. And the telescopic shaft 11 can guide the movement of the mounting seat 10. When the wire cutting assembly and the alignment assembly connected to the mounting seat 10 descend to the designated position, the alignment cylinder 14 can drive the alignment jaws 15 to move. After the two sets of alignment jaws 15 are closed, they can align and fix the coil 21, enabling the coil 21 to remain in the correct position during the cutting process, which is beneficial to ensuring the accuracy of wire cutting. Then, the wire cutting cylinder 12 can drive the cutting jaws 13 to move. After the cutting jaws 13 are closed, they can cut the coil 21, thus completing the wire cutting work of the coil 21 and being beneficial to ensuring the integrity of the cut of the coil 21.

[0041] Please refer to Figures 1 - 6 , the material receiving assembly includes a second guide rail 17. The connection mode of the second guide rail 17 and the support plate 16 is a fixed connection. A slide seat 18 is slidably connected to the upper surface of the second guide rail 17. One side of the slide seat 18 is fixedly connected to a material receiving box 20. A connecting rod 19 is rotatably connected to the upper surface of the slide seat 18. The other end of the connecting rod 19 is rotatably connected to the mounting seat 10;

[0042] The principle of being able to collect the waste coil 21 is as follows: During the lifting and lowering process of the mounting seat 10, it will drive the slide seat 18 to move through the connecting rod 19, causing the slide seat 18 to drive the material receiving box 20 to slide on the upper surface of the second guide rail 17. And when the mounting seat 10 rises, the slide seat 18 will drive the material receiving box 20 to move towards the position where the stator 7 is located. When the mounting seat 10 descends, the slide seat 18 will drive the material receiving box 20 to move in the opposite direction of the position where the stator 7 is located. When the material receiving box 20 moves to a position close to the stator 7, the waste coil 21 will fall down and fall into the interior of the material receiving box 20. The waste coil 21 can be centrally collected through the material receiving box 20, thereby preventing the waste coil 21 from contaminating the equipment.
