Brushless Direct Current Motors (BLDC motors), with their significant advantages such as high efficiency, quiet operation, long lifespan, and precise control, are gradually replacing traditional brushed motors and becoming the mainstream choice for drive equipment. However, in the production process of brushless motor stators, the problem of waste wire has become a key factor restricting the improvement of production efficiency and product quality. Therefore, the development of a waste wire-free device for brushless motor stators is urgently needed.

[0003] In the traditional brushless motor stator production process, the winding stage is the main source of waste wire. Due to the precision limitations of the winding equipment, the varying skill levels of operators, and the complexity of the winding process, problems such as loose coil arrangement, tangled wire ends, and wire breakage are prone to occur during winding. For example, when the tension control of the winding equipment is inaccurate, the wire may be subjected to excessive tension and break during winding; if the operator is not skilled in manual winding, the wire may also cross or tangle, resulting in waste wire. To address this problem, the inventors have proposed a waste wire-free device for brushless motor stators. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0019] like Figure 1-4 As shown, this utility model discloses a waste wire removal device for a brushless motor stator, comprising a support assembly, a wire clamping mechanism, a wire twisting mechanism, a transmission assembly, and a lifting assembly. The wire clamping mechanism is located on the inner wall of the support assembly and is used to clamp, guide, and transfer enameled wire. The wire twisting mechanism is located at one end of the support assembly. The transmission assembly is located at one end of the support assembly and is connected to the wire twisting mechanism to drive the wire twisting mechanism to operate. The lifting assembly is located at one end of the support assembly and is used to raise and lower the position of the stator. The wire clamping mechanism includes a connecting plate 21 and a fixing plate 22. The connecting plate 21 is located at one end of the support assembly, and the fixing plate 22 is located at one end of the connecting plate 21.

[0020] A wire clamping cylinder 201 is provided at one end of the wire clamping mechanism. One end of the wire clamping cylinder 201 is provided with a wire clamping nozzle 202 for clamping the enameled wire. One end of the wire clamping cylinder 201 is provided with a cutting part 203 corresponding to the wire clamping nozzle 202 for cutting the enameled wire.

[0021] Specifically, the wire-clamping cylinder 201 clamps the enameled wire through the wire-clamping nozzle 202, and the driving cylinder 23 pushes the connecting block 24 and the sliding block 27 to move laterally along the sliding guide rail 26, so that the enameled wire is smoothly guided to the stator winding point. The precise fit between the sliding groove 25 and the sliding guide rail 26 ensures that there is no deviation or tangling during the wire clamping process. When the winding is completed to the preset length, the shearing part 203 of the wire-clamping cylinder 201 closes quickly, cutting the enameled wire. The shearing action and the opening and closing of the wire-clamping nozzle 202 are driven by the same cylinder, ensuring a precise match between the shearing timing and the clamping force, avoiding wire breakage or wire end residue.

[0022] The twisting mechanism includes a transmission rod 34 and a twisting rod 31. The transmission rod 34 is located on the inner wall of the transmission assembly, and the twisting rod 31 is located at one end of the transmission rod 34. A lifting cylinder 33 is provided between the twisting rod 31 and the transmission rod 34. A twisting groove 32 is provided at one end of the twisting rod 31 for twisting the enameled wire on the terminal.

[0023] Specifically, after winding is complete, the twisting mechanism performs the final twisting action. The twisting rod 31 twists and reinforces the enameled wire on the stator terminals through the twisting groove 32, ensuring the coil is secure and does not come loose. The lifting assembly descends synchronously, moving the wound stator out of the working area. The telescopic rod 56 and the limiting sleeve 57 provide double buffer protection during the lifting process, preventing the enameled wire from coming loose due to inertial swaying of the stator. The entire process, through closed-loop control of wire clamping-winding-twisting-cutting, completely eliminates the waste wire problem in traditional winding processes.

[0024] One end of the fixed plate 22 is provided with a driving cylinder 23, one end of the driving cylinder 23 is provided with a connecting block 24, one end of the connecting block 24 is provided with a sliding block 27, one end of the sliding block 27 is provided with a sliding guide rail 26, and can perform lateral reciprocating motion relative to the sliding guide rail 26. One end of the sliding guide rail 26 is provided with a sliding groove 25, which is located on the back of the fixed plate 22. The wire clamping cylinder 201 is located at one end of the sliding block 27.

[0025] The transmission assembly includes a transmission motor 41, transmission wheels 42, and transmission belts 43. The transmission motor 41 is located at one end of the support assembly, and at least three transmission wheels 42 are located at the output end of the transmission motor 41. The transmission belts 43 are respectively sleeved on the inner sidewalls of the transmission wheels 42. The upper surface of the transmission wheels 42 is provided with a protective housing 1 for protecting the transmission wheels 42 and the transmission belts 43. The transmission rod 34 is located on the inner sidewall of the transmission wheels 42.

[0026] Specifically, after the drive motor 41 starts, it drives multiple drive wheels 42 to rotate synchronously via the drive belt 43. The protective housing 1 isolates the transmission components to prevent external interference. The drive rod 34 rotates with the drive wheels 42, thereby driving the twisting rod 31 to rotate. The twisting groove 32 at one end of the twisting rod 31 arranges the enameled wire in an orderly manner during rotation, preventing the coil from becoming loose. The lifting cylinder 33 adjusts the height of the twisting rod 31 in real time, achieving three-dimensional winding in coordination with the winding rhythm.

[0027] The lifting assembly includes a motor support plate 51, a horizontal plate 52, and a support base 53. The horizontal plate 52 is located at one end of the support assembly, the support base 53 is located at one end of the horizontal plate 52, the motor support plate 51 is located at one end of the support base 53, a lifting motor 54 is provided at one end of the motor support plate 51, a lifting rod 55 is provided at one end of the lifting motor 54, the lifting rod 55 is located between the horizontal plate 52 and the lifting motor 54, at least two telescopic rods 56 are provided on the upper surface of the horizontal plate 52, and a limiting sleeve 57 is provided on the inner side wall of the telescopic rod 56, the limiting sleeve 57 is located between the horizontal plate 52 and the mounting part of the telescopic rod 56.

[0028] Specifically, the lifting assembly starts first. The lifting motor 54 drives the horizontal plate 52 and the support base 53 to move upward through the lifting rod 55, thereby raising the mounting plate 11 and the support frame 12 to the preset height. At this time, the stator is precisely positioned in the working area of ​​the wire clamping mechanism.

[0029] The support assembly includes a mounting plate 11, a support frame 12, and a back plate 13. The mounting plate 11 is located on the upper surface of the horizontal plate 52, the support frame 12 is located on the inner side wall of the mounting plate 11, the back plate 13 is located at one end of the support frame 12, the connecting plate 21 is located at one end of the support frame 12, the drive motor 41 is located at one end of the back plate 13, and the horizontal plate 52 is located at one end of the mounting plate 11.

[0030] Specifically, the mounting plate 11 is fixed to the horizontal plate 52, the support frame 12 and the back plate 13 form the main frame, and the connecting plate 21 and the fixing plate 22 form the mounting base of the clamping mechanism. The motor support plate 51 of the lifting assembly drives the lifting rod 55 through the lifting motor 54, which drives the horizontal plate 52 and the support assembly to lift as a whole, so as to achieve precise positioning of the stator in the Z-axis direction; the telescopic rod 56 cooperates with the limiting sleeve 57 to ensure that the lifting process is smooth and without shaking.

[0031] The high-precision wire clamping nozzle 202 of the wire clamping mechanism works in conjunction with the shearing part 203 to achieve precise control of the entire process of clamping and transferring the enameled wire to the shearing part, avoiding the wire breakage problem caused by inaccurate tension control during the traditional winding process. The twisting groove 32 of the twisting mechanism can automatically twist the enameled wire on the terminal, ensuring that the coil is tightly arranged without tangling, thus eliminating the waste wire phenomenon such as wire end tangling and wire breakage from the root.
