[0079] like Figure 10As shown, the take-up device 32 includes a take-up base plate 321, a take-up rotating disk 322, a take-up guide plate 323, a take-up slider 324, take-up teeth 325, and a take-up electric cylinder. The take-up base plate 321 is recessed to form a groove, and the take-up rotating disk 322 is embedded in the groove. The take-up guide plate 323 is fixedly connected to the take-up base plate 321. The take-up guide plate 323 is provided with several guide grooves, which are slidably connected to the take-up slider 324. The take-up slider 324 is provided with corresponding first and second holes.

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 the take-up electric cylinder.

[0080] like Figure 11 As shown, the wire pressing device 33 includes a fixedly mounted wire pressing electric cylinder, 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 opened along the wire pressing rotating disk 333; several sliding grooves are opened on the wire pressing fixing plate 335; the pressing mechanism 334 is embedded in the sliding groove and slidably connected to the wire pressing fixing plate 335, and 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 electric cylinder.

[0081] Figure 12 As shown, the rotating device 34 includes a rotating gear 341, a turntable 342, and a rotating motor 343; the outer ring of the turntable 342 is provided with a gear ring 344, which meshes with the rotating gear 341, and the rotating gear 341 is fixed to the output end of the rotating motor 343.

[0082] Figure 13 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 free end of the piston rod of the top wire electric cylinder 352 is fixedly connected to the support base 353.

[0083] In use, the flat wires are laid on the support frame of the material channel 303 in sequence. After being vibrated by the vibration device, the flat wires move to the left continuously. The distance between the first and second stop blocks is large enough to accommodate one flat wire. After the first and second stop blocks divide the flat wires, a single flat wire moves to the left of the second stop block after vibration, located above the material channel top line cylinder. At this time, the material channel top line cylinder extends the free end of the piston rod to lift the flat wire, making it convenient for the robot arm 304 set above the material channel 303 to grab a flat wire.

[0084] The robotic arm 304 moves to insert the flat wire from above the pre-insertion device 301. As the flat wires are inserted one by one, the following steps are performed: First, the take-up device 32 starts working, the take-up electric cylinder works, and drives the take-up rotating disk 322 to rotate. Because the holes on the take-up rotating disk 322 are distributed in an inclined direction on the circumference of the take-up rotating disk 322, the connecting piece slides on the rotating disk 322, so that the take-up slider 324 slides back and forth in the guide groove of the take-up guide plate 323, which drives the take-up teeth 325 to move back and forth, gradually gathering the flat wires into the take-up grooves of each take-up tooth 325.

[0085] Then, the pushing device 31 operates, and the pushing assembly 315 opens, remaining in a non-closed state. At this time, the flat wire is spread out and tilted. Then, the pushing electric cylinder 311 starts operating, its piston rod extending and driving the pushing rotating ring 313 to rotate via the connecting block. This, in turn, drives the pushing assembly 315 towards the center of either the pushing rotating ring 313 or the pushing guide ring 314. The pushing assembly 315 gradually closes, forming a closed ring. The flat wire located within the pushing fixed ring 312, the pushing rotating ring 313, and the pushing guide ring 314 is pushed into an upright state. Then, the piston rod of the pushing electric cylinder 311 retracts, and the connecting block drives the pushing rotating ring 313 to rotate in the opposite direction. The pushing assembly 315 moves in the opposite direction to the center of either the pushing rotating ring 313 or the pushing guide ring 314, gradually opening. When the extended end of the driving device 311 is fully retracted, the pushing rotating ring 313 returns to its initial position, completing the entire pushing process.

[0086] Next, the wire pressing device 33 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.

[0087] After the above-described wire-retracting, pushing, and pressing processes, robotic arm 304 begins inserting the wires. After inserting each wire, as follows: Figure 12 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. The next hole to be inserted is rotated to the insertion position and then the rotation stops. After the insertion is completed, the rotation is repeated, and the insertion is carried out in sequence.

[0088] When the robotic arm 304 has inserted all the spools in sequence, the wire-lifting device 35 and the wire-lifting electric cylinder 352 work to lift the support base 353, and the robotic arm 304 can pick up the entire spool A to complete the pre-insertion step.

[0089] Then the robotic arm 304 picks up the spool A and places it above the combing device 302; then the lifting electric cylinder lifts the combing core component 3024 as a whole, and the combing core component 3024 realizes the combing action of the wire harness through the action of the wire-strapping electric cylinder.

[0090] When the core component 3024 is working, the cable-strapping electric cylinder extends, driving the cylinder connector forward and pushing the take-up guide fork on the base tray 3021 to perform a circular motion. Because the holes on the take-up guide plate 3022 are elongated and diagonally distributed around its circumference, the sliding column 3023 slides within the holes of the guide plate 245, gradually moving from the circumference towards the center. The sliding column 3023 engages with the cable-strapping teeth 3029, causing the teeth to slide back and forth on the cable-strapping slide plate 3028. The sharp teeth of the cable-strapping teeth 3029 slide back and forth, combing the cable. Several cable-strapping teeth 3029 form a ring, achieving the purpose of cable combing as the cable-strapping electric cylinder operates.

[0091] After the wire bundle of spool A is combed, it becomes neat and tidy. The robotic arm 304 then holds the wire bundle 21 and continues to descend, inserting the entire spool A into the stator, thus completing the insertion process.

[0092] like Figures 14 to 17 As shown, the flaring device 400 includes a base plate 41, a flaring motor 421, a positioning motor 422, a gear adjustment assembly 43, a first gripper fixing plate 44, a first drive wheel 45, an upper rotary support 46, a lower rotary support 47, a second drive wheel 48, and a first gripper 49.

[0094] like Figure 15As shown, the first gripper 49 includes a connecting rod shaft 491, a length adjusting rod 492, a first gripper base plate 493, a pneumatic gripper 494, and a clamping block 495. The connecting rod shaft 491 is bolted to the rotating gear ring 461. A first connecting rod 4911 is mounted on the connecting rod shaft 491. The connecting rod shaft 491 is rotatably connected to the first connecting rod 4911. One end of the length adjusting rod 492 is connected to the first connecting rod 4911, and the other end is connected to the first gripper base plate 493 through a second connecting rod 4912. A pneumatic gripper 494 is fixedly connected to the first gripper base plate 493, and the output end of the pneumatic gripper 494 is fixedly connected to the clamping block 495.

[0095] The first gripper fixing plate 44 is provided with a flared slide rail 441, and the first gripper base plate 493 is slidably connected to the flared slide rail 441.

[0096] like Figure 17 As shown, the gear adjustment assembly 43 includes a stop plate and an adjusting bolt; the stop plate is fixed to the base plate 41, the shift motor 422 is provided with a protruding flared connector, the first drive wheel 45 is mounted on the flared connector, and the adjusting bolt passes through the stop plate to adjust the distance between the first drive wheel 45 and the rotating gear ring 461.

[0097] When in use, when the flaring motor 421 reverses, it transmits power to the first drive wheel 45 through the reducer, which drives the rotating gear ring 461 to rotate. The rotation of the rotating gear ring 461 drives the connecting rod shaft 491 to rotate. The length adjustment rod 492 can extend and retract, which in turn drives the first gripper base plate 493 to slide on the flaring slide rail 441, causing the first gripper 49 on the first gripper fixing plate 44 to move forward.

[0098] Once in position, the flaring motor 421 stops, the pneumatic gripper 494 closes, and the clamping block 495 clamps the flat wire. Then, the flaring motor 421 rotates forward, pulling the flat wire outward to achieve the desired angle. The pneumatic gripper 494 opens the clamping block 495 to release the flat wire, and the flaring motor 421 continues to rotate forward, returning to its original position.

[0099] When the positioner motor 422 is working, the second drive wheel 48 drives the lower rotary support 47 to rotate at a set angle. Since the lower rotary support 47, the upper rotary support 46 and the first gripper fixing plate 44 are fixed as one unit, the first gripper 49 rotates with the operation of the positioner motor 422.

[0100] As the vehicle is used, wear will cause the transmission between the first drive wheel 45 and the rotating gear ring 461 to become unstable. Therefore, a gear adjustment assembly 43 is provided, which allows manual adjustment of the adjusting bolt to control the distance between the first drive wheel 45 and the rotating gear ring 461. Similarly, the same gear adjustment assembly 43 is provided to adjust the distance between the second drive wheel 48 and the lower rotary support 47.

[0101] The flaring motor 421 controls the first gripper 49 to move back and forth to achieve flaring, and the position change motor 422 works to switch the position of the first gripper 49. When the number of the first gripper 49 is set to 6, it flares 6 flat wires at a time, which can realize the flaring operation of the stator with a wire number that is an integer multiple of 6.

[0109] Preferably, along the length of the first mounting plate 621, the two slide rail pairs 622 are mirror images of the center of the first mounting plate 621 to ensure that the second gripper 6251 is in the same plane, facilitating the gripping of the flat wire stator winding 606. A limiting block 623 is also provided on the first mounting plate 621, located at the center of the first mounting plate 621, between the two slide rail pairs 622, to ensure that the flat wire stator winding 606 is located at the center of the gripping and flipping device during gripping.

Preferably, the first waist-shaped grooves are arc-shaped waist-shaped grooves.

[0117] like Figure 21As shown, a flattening guide ring 674 is positioned above a flattening rotating ring 673, and its inner ring is fixedly connected to a third washer ring 675. N flattening guide ring grooves are formed along the radial direction of the flattening guide ring 674. These grooves are through-type grooves, connecting the inner and outer rings of the flattening guide ring 674. The N grooves are evenly distributed circumferentially on the flattening guide ring 674. Within each flattening guide ring groove, N second waist-shaped grooves are formed along its length. These second waist-shaped grooves are straight, and their length direction is the same as the extending direction of the flattening guide ring groove.

[0118] The guide assembly 678 is disposed in the first waist-shaped groove and the second waist-shaped groove, and the cutter assembly 677 is disposed in the flattening guide ring groove. The guide assembly 678 and the cutter assembly 677 are fixedly connected. The cutter assembly 677 can move in the flattening guide ring groove under the drive of the flattening drive device 66.

[0119] When the flattening drive device 66 drives the flattening rotating ring 673 to rotate, it can drive the guide component 678 set in the first waist-shaped groove and the second waist-shaped groove to move, and then drive the cutter component 677 to move in the flattening guide ring groove. When the cutter moves to the inner ring of the flattening guide ring 674, it can flatten the flat wire inserted in the fixed cutter disc 676. After the flattening process is completed, the flattening drive device 66 flips, driving the cutter component 677 to move to the outer ring of the flattening guide ring 674 to prepare for the next flattening process.

Mounting holes are respectively provided on the second and third steps, which cooperate to position and install the cutter portion.

[0123] When the cutting drive device 66 drives the cutter assembly 677 to move toward the inner ring of the cutting guide ring 674, the cutter part can be accommodated in the groove of the third pad ring to cut the flat wire inserted on the fixed cutter disc 676.

[0124] N groups of flat cutting slots are formed radially along the fixed cutter head 676, and these N groups are evenly distributed circumferentially around the fixed cutter head 676. Each group of flat cutting slots includes M flat cutting slots arranged radially along the fixed cutter head 676, where M is a positive integer greater than or equal to 1. M is related to the number of flat wire layers in the flat wire stator winding 606. For example, M can be 4, meaning the group of flat cutting slots includes 4 flat cutting slots arranged radially along the fixed cutter head 676, allowing 4 layers of flat wire to be inserted.

[0125] The positioning assembly 679 includes a first positioning part 6791 fixedly mounted on the cutting flat fixing base 65, a second positioning part 6792 sleeved outside the first positioning part 6791, and a third positioning part 6793.

[0127] The flattening device 603 also includes a flattening fixing ring 680, which is fixedly disposed above the flattening guide ring 674.

[0128] like Figure 23 As shown, the flattening device 600 also includes a flattening device 604, which is fixedly connected to the conveying device 601. The flattening device 604 is used to prevent the flat wire of the flat wire stator from exceeding the preset height.

Preferably, there are two guiding mechanisms 6043, which are respectively disposed on both sides of the flattening drive part 6042 to guide the movement of the flattening part 6047, so as to make the movement of the flattening part 6047 smoother and prevent the flattening part 6047 from deviating during the movement.

[0132] To facilitate the fixing and positioning of the flat wire stator winding 606, the flattening device 600 also includes a positioning and fixing device 605. Before placing the flat wire stator winding 606 onto the flattening device 603, the flat wire stator is first fixed on the positioning and fixing device 605 to achieve pre-fixing and pre-positioning of the flat wire stator winding 606.

[0133] like Figures 24 to 25 As shown, the positioning and fixing device 605 includes a first flat-cut fixing ring 6051, a second flat-cut fixing ring 6052, a connecting ring 6054 fixedly connected to the bottom of the first flat-cut fixing ring 6051, a first wire-fixing ring 6055 fixedly connected to the bottom of the second flat-cut fixing ring 6052, a second wire-fixing ring 6056 disposed at the bottom of the first wire-fixing ring 6055, a third flat-cut fixing ring 6058 disposed at the bottom of the second wire-fixing ring 6056 and fixedly connected to the first wire-fixing ring 6055, a fourth flat-cut fixing ring 6057 snapped into the second wire-fixing ring 6056 and fixedly connected to the first wire-fixing ring 6055, a positioning ring 6059 fixedly connected to the first wire-fixing ring 6055, and an adjusting component 6053.

[0134] Two second connecting parts are symmetrically arranged on the outer ring of the first flattening fixing ring 6051. Each of the two second connecting parts has a mounting hole, and a connecting block is fitted into the mounting hole, thus fixing the connecting block to the second flattening fixing ring 6052. The second connecting parts are rotatably connected to the adjusting assembly 6053. When the adjusting assembly 6053 adjusts the rotation of the second fixing ring 6056, the adjusting assembly 6053 rotates around the connection point between the second connecting parts and the adjusting assembly 6053 as the fulcrum.

[0135] A first recess is provided on the outer ring of the first flat-cut fixing ring 6051. The outer diameter of the connecting ring 6054 is larger than the outer ring size of the first recess, and the outer ring of the connecting ring 6054 and the first recess form an inner groove.

[0136] A protrusion is provided on the inner ring of the second flat-cut fixing ring 6052, and the protrusion is accommodated in the inner groove; the protrusion and the groove cooperate with each other to install and position the second flat-cut fixing ring 6052. Two fourth inner recesses are symmetrically provided on the second flat-cut fixing ring 6052, and the two second connecting parts are respectively accommodated in the two fourth inner recesses.

[0137] Two third connecting parts are symmetrically arranged on the outer ring of the first wire-fixing ring 6055, and the two third connecting parts are fixedly connected to the adjusting assembly 6053. N first wire-fixing groove groups are formed along the radial direction of the first wire-fixing ring 6055, and the N first wire-fixing groove groups are evenly distributed along the circumference of the first wire-fixing ring 6055, where N is a positive integer greater than or equal to 2. Each first wire-fixing groove group includes M first wire-fixing grooves, and the M first wire-fixing grooves are evenly arranged along the radial direction of the first wire-fixing ring 6055, where M is a positive integer greater than or equal to 1. Preferably, the size of the first wire-fixing grooves gradually decreases along the circumference of the first wire-fixing ring 6055.

[0138] A second concave portion is provided on the inner ring of the third flat-cut fixing ring 6058. Two third concave portions are also symmetrically provided on the third flat-cut fixing ring 6058. The two third concave portions are connected to the second concave portion to form a receiving groove. The second wire fixing ring 6056 is received in the receiving groove. The ring body of the second wire fixing ring 6056 is received in the second concave portion, and the two fourth connecting portions are respectively received in the two third concave portions.

[0139] The third flat fixing ring 6058 is provided with a scale to indicate the distance the second fixing ring 6056 moves.

[0140] Two fourth connecting portions are symmetrically arranged on the outer ring of the second wire-fixing ring 6056. The ring body of the second wire-fixing ring 6056 is housed within the second recess, and the two fourth connecting portions are respectively housed within the two third recesses. Preferably, the size of the third recess is larger than the size of the fourth connecting portion, allowing the fourth connecting portion to rotate within the third recess. One end of the fourth connecting portion extending out of the third recess is fixedly connected to the adjusting assembly 6053. Adjusting the adjusting assembly 6053 drives the second wire-fixing ring 6056 to rotate relative to the first wire-fixing ring 6055.

[0141] N second wire-fixing groove groups are formed along the radial direction of the second wire-fixing ring 6056, and the N second wire-fixing groove groups are evenly distributed in the circumferential direction of the second wire-fixing ring 6056. When the flat wire stator is not installed, the positions of the first wire-fixing groove group and the second wire-fixing groove group overlap, so that the flat wire of the flat wire stator can be inserted into the first wire-fixing groove group and the second wire-fixing groove group.

[0142] Each group of second wire-fixing grooves includes M second wire-fixing grooves, which are uniformly arranged along the radial direction of the second wire-fixing ring 6056. Preferably, the size of the second wire-fixing grooves gradually increases along the circumference of the second wire-fixing ring 6056. In the non-working state, the first and second wire-fixing grooves overlap each other.

[0143] The outer ring of the fourth flat fixing ring 6057 is provided with a first step portion, and the inner ring of the second wire fixing ring 6056 is provided with a second step portion. The first step portion and the second step portion are engaged to fix the second wire fixing ring 6056.

[0144] The adjusting assembly 6053 includes a connecting rod, a sliding part sleeved on the connecting rod, and an adjusting part threadedly connected to the connecting rod; one end of the connecting rod is rotatably connected to the second connecting part, and the other end of the connecting rod is threadedly connected to the adjusting part. The sliding part is fixedly connected to the third connecting part and / or the fourth connecting part; for example, the positioning and fixing device is provided with four adjusting assemblies 6053, wherein the sliding parts of two adjusting assemblies 6053 are fixedly connected to the third connecting part, and the sliding parts of two adjusting assemblies 6053 are fixedly connected to the fourth connecting part.

[0145] Adjusting the connection length between the adjusting part and the connecting rod drives the sliding part to slide on the connecting rod, thereby driving the second wire fixing ring 6056 to rotate relative to the first wire fixing ring 6055, thereby reducing the area of ​​the overlapping part of the first wire fixing groove and the second wire fixing groove, so that the first wire fixing ring 6055 and the second wire fixing ring 6056 press against each other to fix the flat wire of the flat wire stator.

[0146] The adjusting assembly 6053 also includes a spring sleeved on the connecting rod, the connecting rod having a blocking part, and the spring located between the blocking part and the sliding part.

[0147] When the positioning and fixing device 605 is not working, the spring is in its original state of neither compression nor extension. When the adjusting part is adjusted to increase the connection length between the adjusting part and the connecting rod, the adjusting part pushes the sliding part to slide towards the blocking part. At this time, the sliding part compresses the spring, putting it in a compressed state. The movement of the sliding part causes the second wire-fixing ring 6056 to rotate relative to the first wire-fixing ring 6055. This reduces the overlapping area between the first and second wire-fixing grooves, meaning that the first and second wire-fixing rings 6055 and 6056 apply opposite forces to the flat wire, thus clamping and fixing the flat wire, and consequently fixing the flat wire stator. When it is necessary to remove the flat wire stator from the positioning and fixing device, the adjusting part is adjusted to decrease the connection length between the adjusting part and the connecting rod. At this time, the spring rebounds from the compressed state, driving the sliding part to move away from the blocking part, thereby returning the second wire-fixing ring 6056 to its initial position.

[0148] The working process of the flattening equipment 600 is as follows: Normally, the flat wire stator winding 606 is placed on a pallet, which can move on a roller conveyor. When the flat wire stator winding 606 is conveyed to the flattening station, it stops moving. The conveying device 601 drives the clamping and flipping device 602 and the flattening device 604 to move to the flat wire stator winding. At this time, the flat wire stator winding 606 is located within the clamping space. The second gripper drive unit 6255 drives the second gripper assembly 625 to move relative to each other, and the two second gripper assemblies 625 clamp the flat wire stator winding 606. Then, the conveying device 601 drives the clamping and flipping device 602 and the flattening device 604 to move vertically upwards to the first preset position. After being placed, the clamping and flipping drive unit 61 drives the clamping and flipping device 602 to flip 180°. The conveying device 601 drives the clamping and flipping device 602 and the flattening device 604 to move to the preset work position. Then, the second gripper drive unit 6255 drives the second gripper assembly 625 to move towards each other. The two second gripper assemblies 625 release the flat wire stator winding 606. At this time, the flat wire stator winding 606 is flipped 180° and placed on the preset work position. At this time, the conveying device 601 drives the clamping and flipping device 602 and the flattening device 604 to move upward to the second preset position.

[0149] The operator fixes the flat wire stator winding 606 on the positioning and fixing device 605. Then, the conveying device 601 drives the clamping and flipping device 602 and the flattening device 604 to descend. The clamping and flipping device 602 clamps the flat wire stator. The conveying device 601 drives the clamping and flipping device 602 and the flattening device 604 to move above the cutting and flattening device 603. The clamping and flipping device 602 drives the flat wire stator winding 606 to flip 180°. Then, the flattening drive unit of the flattening device 604 drives the flattening part 6047 to extend, and the wire pressing part presses the flat wire of the flat wire stator winding 606. Then, the conveying device 601 drives the clamping and flipping device 602 and the flattening device 604 to descend, placing the flat wire stator winding 606 and the positioning and fixing device 605 on the cutting device 603. After that, the clamping and flipping device 602 releases the flat wire stator winding 606, and the conveying device 601 drives the clamping and flipping device 602 and the flattening device 604 to rise to the third preset position.

[0150] The flattening drive device 66 drives the cutter assembly 677 towards the center of the flat wire stator winding 606, flattening the flat wire of the flat wire stator winding 606. Then, the flattening drive device 66 reverses, driving the cutter assembly 677 away from the center of the flat wire stator winding 606, completing the flattening of the flat wire of the flat wire stator winding 606. Afterwards, the conveying device 601 drives the clamping and turning device 602 and the flattening device 604 to descend.
