Description

Technical Field

[0001] This invention belongs to the technical field of motor assembly equipment, and particularly relates to a flat wire stator winding insertion device. Background Technology

[0002] Flat-wire motors are increasingly being used in the electric vehicle field. Flat-wire motors offer advantages such as high copper fill factor, improved heat dissipation in the motor windings, increased winding withstand voltage, and reduced winding end length, thereby enhancing the motor's torque and power density. As a core component of new energy vehicles, the electric drive system significantly impacts their performance. The definition of a flat-wire motor specifically refers to a change in the conductor shape used in the stator windings, transforming from multiple thin round wires to several thick rectangular wires, commonly known as flat wires. Currently, flat-wire conductors are mainly used in large-scale motor equipment such as wind turbines and hydroelectric generators, and in recent years, they have seen widespread application in mid-to-high-end vehicle generators from foreign brands.

[0003] Flat wire motors have advantages such as high slot fill factor, high power, and high torque, as well as good heat dissipation performance, thus gaining widespread use. During the assembly and production of flat wire motors, U-shaped flat wires need to be inserted into the stator. However, the slots on the stator are small, making rapid insertion of the flat wires difficult. Existing insertion devices first insert the flat wire into a fixture, then remove it from the fixture and transfer it to the stator. While this indirect insertion method is less difficult than direct insertion, it requires specialized clamps to hold the flat wire during the transfer process. During clamping, the flat wire may tilt or loosen, resulting in incomplete alignment with the stator slots and causing inconvenience. Furthermore, different types of clamps are needed for different flat wire models; if multiple wire models are available, multiple types of clamping devices need to be prepared, increasing costs.

The connector passes through the take-up guide plate 323 and slides in the hole of the take-up rotating disk 322. The take-up rotating disk 322 is fixedly connected to a take-up electric cylinder 326.

[0047] like Figure 16 and Figure 17 As shown, the wire pressing device 33 includes a fixedly mounted wire pressing cylinder 331, a cover plate 332, a wire pressing rotating disk 333, a pressing mechanism 334, and a wire pressing fixing plate 335. The wire pressing rotating disk 333 is mounted on the wire pressing fixing plate 335, and several through holes are formed along the wire pressing rotating disk 333. Several sliding grooves are formed on the wire pressing fixing plate 335. The pressing mechanism 334 is embedded in the sliding grooves and slidably connected to the fixing plate 335. The pressing mechanism 334 has a protrusion that is inserted into the through hole of the wire pressing rotating disk 333. The wire pressing rotating disk 333 is connected to the wire pressing cylinder 331.

[0048] Figure 18 As shown, the rotating device 34 includes a gear 341, a turntable 342, and a rotary motor 343; the turntable 342 has a gear ring 344 on its outer ring, the gear ring 344 meshes with the gear 341, and the gear 341 is fixed to the output end of the rotary motor 343;

[0049] Figure 19 As shown, the top wire device 35 includes a vertical rod 351, a support base 353, and a top wire electric cylinder 352; the vertical rod 351 is connected to the bottom of the rotating device 34, and the support base 353 is fixedly connected to the free end of the piston rod of the top wire electric cylinder 352.

[0050] In use, the flat wires are laid on the support frame 13 of the material channel 1 in sequence. After being vibrated by the vibration device 14, the flat wires move continuously to the left. The distance between the first stop block 15 and the second stop block 16 is large enough to accommodate one flat wire. After the first stop block 15 and the second stop block 16 divide the flat wires, a single flat wire moves to the left of the second stop block 16 and above the material channel top line cylinder 17 after vibration. At this time, the material channel top line cylinder 17 extends the free end of the piston rod to lift the flat wire, so that the robot arm 19 set above the material channel 1 can grab one flat wire.

[0051] The robotic arm 19 moves to insert the flat wires from above the pre-insertion device 3. As the flat wires are inserted one by one, the following steps are performed:

[0052] like Figures 13 to 15 As shown, first, the take-up device 32 starts working.

[0053] When the take-up cylinder 326 is working, the free end of the piston extends out, driving the take-up rotating disk 322 to rotate. Because the holes on the take-up rotating disk 322 are distributed in an inclined direction around the circumference of the take-up rotating disk 322, the connecting piece slides on the rotating disk 322, causing the take-up slider 324 to slide back and forth in the groove of the take-up guide plate 323, driving the take-up teeth 325 to move back and forth, gradually gathering the flat line into each take-up tooth 325.

[0054] like Figures 10 to 12 As shown, the pushing device 31 then operates, and the pushing assembly 315 opens, remaining in a non-closed state. At this time, the flat wire spreads out and tilts. Then, the pushing cylinder 311 starts operating, with its piston rod extending and driving the rotating ring 313 to rotate via the connecting block. This, in turn, drives the pushing assembly 315 to move towards the center of the rotating ring 313 or the guide ring 314. The pushing assembly 315 gradually retracts, forming a closed ring. The flat wire located within the fixed ring 312, rotating ring 313, and guide ring 314 is pushed into an upright state. Then, the piston rod of the pushing cylinder 311 retracts, and the connecting block drives the rotating ring 313 to rotate in the opposite direction. The pushing assembly 315 moves towards the opposite direction of the center of the rotating ring 313 or the guide ring 314, gradually opening. When the extended end of the driving device 311 is fully retracted, the connecting part 3131 returns to its initial position, and the entire pushing process is completed.

[0055] like Figure 16 and Figure 17As shown, the wire pressing device 33 then operates. The wire pressing cylinder 331 drives the wire pressing rotating disk 333 to rotate. The pressing mechanism 334 has a protrusion that inserts into the through hole of the wire pressing rotating disk 333. The protrusion drives the pressing mechanism 334 to slide in the sliding groove of the wire pressing fixing plate 335, that is, the pressing mechanism 334 extends towards the center of the wire pressing rotating disk 333, pressing each flat wire. After the flat wire pressing process is completed, the wire pressing cylinder 331 operates, driving the wire pressing rotating disk 333 to rotate in the opposite direction, thereby driving the pressing mechanism 334 to retract. Then the pressing process is repeated, and so on, continuously pressing the flat wires of the outermost ring of the stator, which can press multiple layers of flat wires.

[0056] After the above-described wire-retracting, pushing, and pressing processes, the robotic arm 19 begins inserting the wires. After inserting each wire, as follows: Figure 18 The rotating device 34 shown rotates by an angle, and the rotating motor 343 drives the gear 341 fixed on it to rotate, which in turn drives the turntable 342 to rotate. Each rotation angle makes the next hole that needs to be plugged in rotate to the same position as the previous hole.

[0057] When robotic arm 19 has inserted all the spools in sequence, such as Figure 19 The top wire device 35 shown is in operation: the top wire electric cylinder 352 is working, lifting the support base 353, and the robot arm 19 can pick up the entire spool A to complete the pre-insertion step.

[0058] Then, the robotic arm 19 grips and holds the spool A above the combing device 2; then the lifting cylinder 27 lifts the combing core component 24 to the top, and the combing core component 24 performs the combing action of the wire harness through the action of the cylinder 241.

[0059] When the combing core component 24 is working, the electric cylinder 241 extends and drives the electric cylinder connector 242 to move forward, pushing the guide fork 243 on the base tray 244 to make a circular motion.

[0060] Because the holes on the rotating guide plate 245 are elongated and obliquely distributed around its circumference, the sliding column 246 slides within these holes, gradually converging towards the center from the circumference. The sliding column 246 engages with the wire harness combing teeth 248, causing the combing teeth 248 to slide back and forth on the wire harness sliding groove plate 247. The pointed teeth 2482 of the wire harness combing teeth 248 slide back and forth, combing the wire harness. Several wire harness combing teeth 248 form a ring, simultaneously sliding back and forth with the operation of the electric cylinder 241, thereby achieving the purpose of combing the wire harness.

[0061] After the combing is completed, the wire bundle of spool A needs to be combed to be neat, so that the robot arm 19 can hold the wire bundle 21 and continue to descend, inserting the entire spool A into the stator, and the entire insertion process is completed.

[0062] The present invention has been described above by way of example, but the present invention is not limited to the specific embodiments described above. Any modifications or variations made based on the present invention shall fall within the scope of protection claimed by the present invention.
