Description

Technical Field

[0001] The invention relates to the technical field of rotor production equipment, in particular to rotor production equipment and a winding method for a flat wire motor. Background Art

[0002] The rotor of a motor generally includes a rotor core and a rotor winding. Many manufacturers use high-speed stamping machines to process and produce the rotor core, and then use special equipment to wind copper wire around the rotor core to form a rotor winding. The quality of the rotor is closely related to the processing quality of the rotor core and the winding quality of the rotor winding. The rotor loading of traditional fully automatic rotor winding machines is done manually, which not only has low work efficiency but also has high labor intensity for workers.

[0003] In the prior art, there is a winding device for producing micro motor rotors, such as a winding device with publication number CN114928222A, which includes a base, a winding machine is fixedly connected to the left end of the upper side wall of the base, a bottom groove is opened in the inner cavity of the base, a first motor is fixedly connected to the left end of the inner side wall of the bottom groove, a rotating block is fixedly connected to the output end of the first motor, a rotating drum is fixedly connected to the upper end of the rotating block, the rotating drum is rotatably connected to the upper side wall of the base, a circular frame is fixedly connected to the upper end of the rotating drum, springs are symmetrically fixedly connected to the inner side walls of the circular frame, and an annular clamp is fixedly connected between the two opposite side walls of the springs. After the winding of the rotor is completed, there is no need to close the device, and the processed rotor is directly moved out, and the rotor to be processed is moved to the clamp circular frame for clamping, and then wound, which reduces the idle time of the winding device and greatly improves the processing efficiency of the winding device.

[0004] In order to reduce the idle time of the device after the winding is completed, the processed rotor is directly removed by clamping; however, in actual use, since the winding end of the slotted rotor adopts a slotting method to fix the enameled wire on the slotted disk at the bottom end of the rotor's commutator, it is inconvenient to fix and remove the rotor when winding, and it is not convenient to rotate the slot to one end of the winding machine when winding each slot, and the rotating hole of the rotor wire disk is difficult to accurately align with the rotating shaft.

[0005] Therefore, the present invention proposes a rotor production device and a winding method for a flat wire motor to solve the problem that the existing equipment is inconvenient to fix and remove the rotor during winding, and it is inconvenient to rotate the embedded slot to one end of the winding machine when winding each embedded slot. It can ensure that the rotor does not shake during winding and ensure that the rotor is easy to unload. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] For example, see Figure 1-14, the present invention provides a technical solution: a production device for a rotor of a flat wire motor, including a winding machine body 1 and a winding mechanism 11 and a moving frame 12 installed inside. The bottom surface of the moving frame 12 is movably connected to the inner surface of the winding machine body 1. A clamping mechanism and a rotor placement mechanism 2 are fixedly installed on the upper surface of the moving frame 12. The rotor placement mechanism 2 includes a servo motor 21. The servo motor 21 is fixedly installed on the upper surface of the moving frame 12. A fixed sleeve shaft 211 is fixedly connected to the output shaft of the servo motor 21. A limiting portion 212 is fixedly connected to the upper end of the fixed sleeve shaft 211. The limiting portion 212 is used for sleeving on the inner ring surface of the rotor. A central limiting rod 22 is fixedly connected to the inner surface of the center of the fixed sleeve shaft 211. A threaded portion 221 is provided on the upper surface of the central limiting rod 22. A limited displacement block 23 is threadedly connected to the outer surface of the threaded portion 221. An upper conical sleeve disc 24 is movably connected to the outside of the limited displacement block 23. A lower conical sleeve disc 25 is fixedly connected to the outer surface of the lower side of the fixed sleeve shaft 211.

[0022] Example two, referring to the attached Figure 1-14 , on the basis of Example one, in order to realize the fitting installation of the upper conical sleeve disc 24 and the limited displacement block 23: a receiving groove 230 and an embedding groove 2300 are opened on the upper inner wall of the limited displacement block 23. The receiving groove 230 is in an "L" - shaped groove structure. The embedding grooves 2300 are distributed on both sides of the receiving groove 230 and are symmetrically distributed about the central axis of the receiving groove 230. A locking component is movably installed inside the receiving groove 230. The locking component includes an L - shaped push rod 242. The L - shaped push rod 242 is in an "L" - shaped plate structure. The outer surface of the L - shaped push rod 242 is slidably connected to the inner wall of the receiving groove 230. An extrusion head 2421 is fixedly connected to the lower end of the L - shaped push rod 242. A tension spring 2422 is fixedly connected to the inner surface of the L - shaped push rod 242. The other end of the tension spring 2422 is fixedly connected to the inner wall of the receiving groove 230. The upper conical sleeve disc 24 is in an overall conical structure. A reserved groove 240 is opened on the lower inner wall of the upper conical sleeve disc 24. A clamping groove plate 241 is fixedly connected to the inner ring surface of the reserved groove 240. The clamping groove plate 241 is in a "匚" - shaped block structure. The outer surface of the clamping groove plate 241 is movably embedded in the inner wall of the embedding groove 2300. The inner surface of the clamping groove plate 241 is movably clamped with the outer surface of the extrusion head 2421. After the motor rotor to be wound is sleeved from the upper end of the limiting portion 212, the bottom of the motor rotor is limited and supported by the top of the lower conical sleeve disc 25, and then the upper conical sleeve disc 24 is installed. Specifically, referring to Figure 5 and Figure 6As shown, the index finger and thumb of one hand respectively pinch the extrusion heads 2421 on both sides of the displacement limiting block 23 and push them inwards. At this time, the L-shaped push rod 242 connected to the extrusion head 2421 slides on the inner side of the receiving groove 230, and the tension spring 2422 is stretched at this time. At the same time, one hand holds the upper conical sleeve 24 as a whole, and aligns the clamping groove plate 241 installed on the inner side of the upper conical sleeve 24 with the embedding groove 2300 for preliminary embedding. At this time, the notch position on the inner side of the clamping groove plate 241 is just aligned with the L-shaped push rod 242. When the two fingers pinching the extrusion head 2421 are released, the L-shaped push rod 242 is reset by the elastic storage force of the tension spring 2422. At this time, the L-shaped push rod 242 is just clamped into the missing groove 250 on the inner side of the clamping groove plate 241. In this way, the upper conical sleeve 24 is realized through the limited clamping between the L-shaped push rod 242 and the clamping groove plate 241. Quick assembly between the limit displacement block 23; it should be noted that the optimization of the overall shape of the upper conical sleeve 24 after installation can wrap around the excess wire segments after the motor rotor is wound, so that after the rotor is completely wound, the excess copper wire can be quickly cut off to ensure that the wound coil will not be damaged when the copper wire is cut; and the upper part of the motor rotor can be blocked to avoid being thrown out under the centrifugal action of rotation; in addition, connecting the upper conical sleeve 24 with the limit displacement block 23 can meet the needs of convenient rotation of the limit displacement block 23, facilitate hand grip, increase the hand contact surface, and make the rotation of the limit displacement block 23 more labor-saving; when the motor rotor needs to be removed, it is only necessary to push the L-shaped push rod 242 inward again to disengage the L-shaped push rod 242 from the clamping slot plate 241 to release the restriction on the upper conical sleeve 24.

[0023] Embodiment 3, refer to the attached Figure 1-14 On the basis of the second embodiment, in order to effectively limit the motor rotor and ensure the stability of the winding: the lower surface of the displacement limiting block 23 is movably connected with a collar 231, the collar 231 is annular, and the outer surface of the collar 231 is movably mounted with a hinged rod 1 232, the other end of the hinged rod 1 232 is movably connected with a top plate 235, the inner side of the top plate 235 is rotatably connected with a hinged rod 233 and a hinged rod 3 236, and the other ends of the hinged rod 233 and the hinged rod 3 236 are movably connected with a fixed The inner surface of the fixed sleeve rod 234 is fixedly connected to the outer surface of the central limiting rod 22, and the side view cross-section of the fixed sleeve rod 234 is in the shape of an "I". The surfaces of both ends of the fixed sleeve rod 234 are respectively movably connected to the ends of the hinged rod 233 and the hinged rod 3 236 away from the top tightening plate 235. A compensation bottom plate 2121 is fixedly installed at the lower end of the limiting part 212. An avoidance groove 2120 is opened on the inner wall of the limiting part 212. The inner surface of the avoidance groove 2120 is movably connected to the side of the top tightening plate 235. After the upper conical sleeve 24 and the limit displacement block 23 are assembled, the upper part of the upper conical sleeve 24 is grasped and rotated, and the inner wall of the limit displacement block 23 is adapted to the surface thread of the threaded portion 221. At this time, under the limiting action of the collar 231, the limit displacement block 23 rotates, and the collar 231 gradually descends in the vertical direction. At this time, the collar 231 pushes the surface of the hinged rod 1 232 to change its angle, and the angle spacing between the hinged rod 233 and the hinged rod 1 232 becomes smaller, and the hinged rod 3 236 is synchronously tilted, so that the diameter-changing movement of multiple sets of tightening plates 235 is realized, and then according to the inner ring diameter of the motor rotor, the effective inner diameter tightening of the rotor is realized, which effectively ensures the fixation of the motor rotor position and further improves the stability and accuracy of the winding operation.

[0024] Embodiment 4, refer to the attached Figure 1-14 On the basis of the third embodiment, in order to enhance the overall stability of the motor rotor during winding operation: the lower conical sleeve 25 is a cone structure that is wide at the top and narrow at the bottom, and a notch 250 is provided on the inner wall of the lower conical sleeve 25.

When the tightening plate 235 moves outward, the distance between the connecting rod 2351 and the fixing block 2354 is shortened. Then, the inclination angle of the hinged rod 2353 changes at this time, and through the connection of the hinged rod 2353, the supporting arc plate 2359 and the telescopic sleeve 2356, the supporting arc plate 2359 is gradually flattened while the tightening plate 235 expands outward, so that the supporting arc plate 2359 can support the bottom of the rotor in the initial state, and when the rotor is completely clamped in the tightening plate 235, the top end of the supporting arc plate 2359 gradually lifts the rotor to ensure the stability of the rotor during installation, and through the setting of the connecting spring 2357, the buffering of the rotor during rotation is met to avoid shaking of the rotor during winding operation.
