Description

Technical Field

[0001] The present invention relates to the technical field of rotor production equipment, specifically to a rotor production equipment for flat wire motors and a winding method thereof. 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 during production, and then use special equipment to wind copper wires around the rotor core to form the 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 traditional automatic rotor winding machine feeds the rotor manually, which not only has low work efficiency but also high labor intensity for workers.

[0003] In the prior art, for example, a winding device for producing a micro-motor rotor with a publication number of CN114928222A includes a base. The left end of the upper side wall of the base is fixedly connected with a winding machine. A bottom groove is opened in the inner cavity of the base. The left end of the inner side wall of the bottom groove is fixedly connected with a first motor. The output end of the first motor is fixedly connected with a rotating block. The upper end of the rotating block is fixedly connected with a rotating cylinder. The rotating cylinder is rotatably connected to the upper side wall of the base. The upper end of the rotating cylinder is fixedly connected with a circular frame. The inner side walls of the circular frame are symmetrically and fixedly connected with springs. A ring-shaped clamping plate is fixedly connected between the opposite side walls of the two springs. After the winding of the rotor is completed, it is not necessary to turn off the device. The processed rotor can be directly removed, and the rotor to be processed can be moved to the fixture circular frame for clamping and then winding, reducing the idle time of the winding device and greatly improving the processing efficiency of the winding device.

[0004] In order to reduce the idle time of the device after winding, a method of directly removing the processed rotor by clamping is adopted. However, in actual use, since the winding end of the inserted groove type rotor fixes the enameled wire on the inserted groove disc at the bottom end of the commutator of the rotor by inserting the groove, it is inconvenient to fix and remove during rotor winding. And when winding each inserted groove, it is inconvenient to rotate the inserted groove to one end of the winding machine, and it is difficult for the rotating hole of the rotor wire reel to be accurately aligned with the rotating shaft.

[0005] Therefore, the present invention provides a rotor production equipment for flat wire motors and a winding method thereof to solve the problems that the existing equipment is inconvenient to fix and remove during rotor winding, and it is inconvenient to rotate the inserted groove to one end of the winding machine when winding each inserted groove, which can ensure that the rotor does not shake during winding and is easy to unload the rotor.

A fixed sleeve shaft 211 is fixedly connected to the output shaft of the servo motor 21, and a limited portion 212 is fixedly connected to the upper end of the fixed sleeve shaft 211. The limited portion 212 is used for fitting the inner ring surface of the rotor, and a central limiting rod 22 is fixedly connected to the central inner surface of the fixed sleeve shaft 211, and a threaded portion 221 is provided on the upper end surface of the central limiting rod 22. The outer surface of the threaded portion 221 is threadedly connected to a limited displacement block 23, and an upper conical sleeve disc 24 is movably connected to the outer portion of the limited displacement block 23, and a lower conical sleeve disc 25 is fixedly connected to the lower outer surface of the fixed sleeve shaft 211.

[0041] Embodiment 2, refer to the attached Figures 1 - 14 On the basis of the first embodiment, in order to achieve the adaptive installation of the upper conical sleeve 24 and the displacement limiting block 23: a receiving groove 230 and an embedding groove 2300 are provided on the inner wall of the upper end of the displacement limiting block 23, the receiving groove 230 is 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, and 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 an "L"-shaped plate-like structure, the outer surface of the L-shaped push rod 242 is slidably connected to the inner wall of the receiving groove 230, and the L-shaped push rod 242 is connected to the inner wall of the receiving groove 230. The lower end of the L-shaped push rod 242 is fixedly connected with an extrusion head 2421, and the inner surface of the L-shaped push rod 242 is fixedly connected with a tension spring 2422, and the other end of the tension spring 2422 is fixedly connected with the inner wall of the receiving groove 230; the upper conical sleeve 24 is a cone-shaped structure as a whole, and a reserved groove 240 is provided on the lower inner wall of the upper conical sleeve 24, and a clamping groove plate 241 is fixedly connected to the inner ring surface of the reserved groove 240, and the clamping groove plate 241 is a "匚"-shaped block structure, and the outer surface of the clamping groove plate 241 is movably engaged with the inner wall of the embedded groove 2300, and the inner surface of the clamping groove plate 241 is movably engaged with the outer surface of the extrusion head 2421;

[0042] After the motor rotor to be wound is sleeved by 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 25, and then the upper conical sleeve 24 is installed. Specifically, refer to Figure 5 and Figure 6 As 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.

[0043] Embodiment 3, refer to the attached Figures 1 - 14, on the basis of Embodiment 2, in order to effectively limit the motor rotor and ensure the stable performance of winding: a collar 231 is movably connected to the lower surface of the displacement limiting block 23. The collar 231 is in a ring structure. One end of the hinge rod 232 is movably installed on the outer surface of the collar 231. The other end of the hinge rod 232 is movably connected to the pressing plate 235. The inner sides of the pressing plates 235 are rotatably connected to the hinge rod 233 and the hinge rod 236 respectively. The other ends of the hinge rod 233 and the hinge rod 236 are movably connected to the fixed sleeve rod 234. The inner surface of the fixed sleeve rod 234 is fixedly connected to the outer surface of the central limiting rod 22. The side view cross-section of the fixed sleeve rod 234 is in an "I" shape. The two end surfaces of the fixed sleeve rod 234 are respectively movably connected to the ends of the hinge rod 233 and the hinge rod 236 away from the pressing plate 235. A compensation bottom plate 2121 is fixedly installed at the lower end of the limiting part 212. An avoidance groove 2120 is formed on the inner wall of the limiting part 212. The inner surface of the avoidance groove 2120 is movably connected to the side surface of the pressing plate 235;

[0044] After the upper conical sleeve disc 24 is assembled with the displacement limiting block 23, hold the upper part of the upper conical sleeve disc 24 and rotate it. The inner wall of the displacement limiting block 23 is threadedly adapted to the surface of the threaded part 221. At this time, under the limiting action of the collar 231, the displacement limiting block 23 rotates, and the collar 231 gradually descends in the vertical direction. At this time, the collar 231 pushes the hinge rod 232 on the surface to change the angle, and the included angle spacing between the hinge rod 233 and the hinge rod 232 becomes smaller at this time. The hinge rod 236 tilts at the same time, so as to realize the variable diameter movement of multiple pressing plates 235, and then effectively tighten the inner diameter of the rotor according to the inner ring diameter of the motor rotor, effectively ensuring the fixation of the position of the motor rotor and further improving the stability and accuracy of the winding operation.

[0045] Embodiment 4, referring to the appendix Figures 1 - 14, on the basis of Embodiment 3, in order to enhance the overall stability during the winding operation of the motor rotor: the lower conical sleeve disk 25 has a cone structure with a wider upper part and a narrower lower part. A notch 250 is formed on the inner wall of the lower conical sleeve disk 25. Four groups of notches 250 are provided and are arranged in an equidistant array about the central axis of the lower conical sleeve disk 25. A secondary support assembly is arranged inside the notch 250; the secondary support assembly includes a connecting rod 2351. The upper end of the connecting rod 2351 is fixedly connected to the lower surface of the pressing plate 235. The lower end of the connecting rod 2351 is fixedly connected to a slider 2352. The slider 2352 is slidably installed inside the notch 250. The surface of the slider 2352 is rotatably connected to a fourth articulated rod 2353. The other end of the fourth articulated rod 2353 is movably connected to a supporting arc plate 2359; an articulated seat 2358 is fixedly connected to the inner surface of the supporting arc plate 2359. A telescopic sleeve 2356 is rotatably connected inside the articulated seat 2358. A square sleeve 2355 is slidably connected to the outer surface of the telescopic sleeve 2356. The other end of the square sleeve 2355 is movably connected to a fixing block 2354. The fixing block 2354 is fixedly installed on the inner wall of the notch 250. A connecting spring 2357 is fixedly installed inside the square sleeve 2355. The other end of the connecting spring 2357 is fixedly connected to one end of the telescopic sleeve 2356;

[0046] When the multiple pressing plates 235 change diameters coaxially, the bottom end of the pressing plate 235 is connected to the connecting rod 2351 and moves. And the slider 2352 connected to the bottom end of the connecting rod 2351 slides inside the notch 250. When the pressing plate 235 moves outwards, the distance between the connecting rod 2351 and the fixing block 2354 shortens. Then the inclination angle of the fourth articulated rod 2353 changes at this time. And through the connection of the fourth articulated rod 2353, the supporting arc plate 2359 and the telescopic sleeve 2356, the supporting arc plate 2359 gradually flattens while the pressing plate 235 expands in diameter outwards. In this way, the supporting of the bottom of the rotor by the supporting arc plate 2359 can be realized in the initial state. And when the rotor is completely clamped inside the pressing plate 235, the top end of the supporting arc plate 2359 gradually lifts the rotor, ensuring the stability during the installation of the rotor. And through the setting of the connecting spring 2357, the buffering during the rotation of the rotor is satisfied, and the shaking during the winding operation of the rotor is avoided.

[0047] Embodiment 5, a winding method for a rotor production device of a flat wire motor, which includes the following steps:

[0048] Step 1: Installation and preliminary positioning of the motor rotor: First, the motor rotor to be wound is sleeved and installed through the upper end of the limiting part 212. The bottom of the motor rotor is limited and supported by the top of the lower conical sleeve disk 25 to initially determine the position of the motor rotor;

[0049] Step 2: Install the upper conical sleeve disk 24 on the displacement limiting block 23: Install the upper conical sleeve disk 24 of the wire winding auxiliary device on the displacement limiting block 23. The specific operation includes pinching the extrusion heads 2421 on both sides of the displacement limiting block 23 and pushing inward, so that the L-shaped push rod 242 slides in the receiving groove 230 and stretches the tension spring 2422. At the same time, align the clamping groove plate 241 inside the upper conical sleeve disk 24 with the embedding groove 2300 for preliminary embedding. After releasing the extrusion heads 2421, the L-shaped push rod 242 is elastically reset by the tension spring 2422 and snaps into the notch 250 inside the clamping groove plate 241 to achieve rapid assembly;

[0050] Step 3: Adjust and fix the position of the motor rotor: Hold the upper part of the upper conical sleeve disk 24 and rotate it. Utilize the threaded connection between the displacement limiting block 23 and the threaded part 221, so that the displacement limiting block 23 gradually descends under the limiting action of the collar 231. During this process, the collar 231 pushes the first articulated rod 232 to change the angle, and then through the linkage action of the second articulated rod 233, the third articulated rod 236 and the pressing plate 235, the variable-diameter movement of multiple pressing plates 235 is realized until the inner ring of the motor rotor is effectively tightened to fix its position;

[0051] Step 4: Conduct wire winding operation: After the motor rotor is effectively fixed, use a wire winding machine or other wire winding tools to start the wire winding operation. The specific wire winding method may vary depending on the equipment model and motor specifications, but the core is to precisely wind the wire on the predetermined position of the motor rotor;

[0052] Step 5: Cut off the excess copper wire and remove the motor rotor: After the wire winding is completed, use a tool to cut off the excess copper wire. Then, push the L-shaped push rod 242 again to disengage it from the clamping groove plate 241, release the restriction on the upper conical sleeve disk 24. Finally, remove the motor rotor that has completed the wire winding from the limiting part 212.

The scope of the present invention is defined by the appended claims and their equivalents.
