[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0019] An exemplary embodiment of this application provides a flattened stator winding flattening system, such as... Figure 1 As shown, the flat wire stator winding flattening system includes: a conveying device 601, a clamping and flipping device 602, and a flattening device 603. The conveying device 601 is used to convey the flat wire stator winding 606 to a preset position; the clamping and flipping device 602 is used to clamp and / or flip the flat wire stator winding 606; and the flattening device 603 is used to flatten the flat wire of the flat wire stator winding 606.

[0020] Preferably, the conveying device 601 is fixedly mounted on the base, and the clamping and flipping device 602 is fixedly connected to the conveying device 601. The conveying device 601 can drive the clamping and flipping device 602 to move in the horizontal and vertical directions. The cutting device 603 is fixedly mounted on the cutting device 603 bracket, and the cutting device 603 bracket is fixedly mounted on the base. The cutting device 603 is located below the clamping and flipping device 602.

[0021] Normally, the flat wire stator winding 606 is placed on a pallet and conveyed along the conveyor rollers to the flattening station. The conveying device 601 of the flat wire stator winding flattening system drives the clamping and turning device 602 to move above the flat wire stator. The clamping and turning device 602 clamps the flat wire stator winding 606 and conveys it to the flattening device 603. After the flattening device 603 flattens the flat wire of the flat wire stator winding 606, the clamping and turning device 602 can clamp the flat wire stator winding 606 and place it on the pallet. The pallet continues to run on the conveyor track, transporting the flat wire stator winding 606 to the next station.

[0022] Preferably, the conveying device 601 includes a first conveying mechanism 6011 fixedly mounted on the base and a second conveying mechanism 6012 slidably mounted on the first conveying mechanism 6011. The first conveying mechanism 6011 can drive the second conveying mechanism 6012 to move in the horizontal direction, thereby driving the gripping and flipping device 602 to move in the horizontal direction. The second conveying mechanism 6012 can drive the gripping and flipping device 602 to move in the vertical direction.

[0023] Continue to refer to Figure 1 The first conveying mechanism 6011 includes two first vertical beams fixedly mounted on a base and a crossbeam fixedly mounted between the two vertical beams. Both ends of the crossbeam are fixedly connected to the two vertical beams respectively. A first slide rail assembly and a first driving unit are fixedly mounted on the crossbeam. The second conveying mechanism 6012 is fixedly connected to the slider of the first slide rail assembly. The output end of the first driving unit is fixedly connected to the second conveying mechanism 6012. For example, the first driving unit is a pneumatic cylinder or an electric cylinder. The first driving unit can drive the second conveying mechanism 6012 to slide along the slide rail of the first slide rail assembly, thereby realizing the horizontal movement of the second conveying mechanism 6012.

[0024] The second conveying mechanism 6012 includes a fixed plate fixedly mounted on the slider of the first slide rail assembly, a second driving part fixedly mounted on the fixed plate, a second slide rail assembly fixedly mounted on the fixed plate, and a second vertical beam fixedly connected to the slider of the second slide rail assembly. For example, the second driving part is a pneumatic cylinder or an electric cylinder, which can drive the second vertical beam to slide on the second slide rail assembly, thereby realizing the vertical movement of the second conveying mechanism 6012.

[0025] like Figure 3 As shown, the gripping and flipping device 602 includes a gripper mechanism 62, a third drive unit 61 for driving the gripper mechanism 62 to rotate, and a connecting mechanism 63 connecting the third drive unit 61 and the gripper mechanism 62. For example, the third drive unit 61 is a rotary cylinder, which can drive the gripper mechanism 62 to rotate 180° in the radial direction along the extended end of the third drive unit 61 to achieve the flipping of the gripper mechanism 62.

[0026] like Figure 3 or Figure 4 As shown, the gripper mechanism 62 includes a first mounting plate 621 fixedly connected to the connecting mechanism 63. The lower part of the first mounting plate 621 is provided with two slide rail pairs 622, and a gripper assembly 625 is slidably disposed on each slide rail pair 622. The first mounting plate 621 is also provided with a stop part, which is fixedly disposed at the end of the slide rail pair 622. The stop part is used to stop the slide rail pair 622 and prevent the gripper assembly 625 from falling off the slide rail pair 622.

[0027] 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 grippers 6251 are 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.

[0028] The limiting block 623 has grooves on both side walls, and the protruding end of the fourth driving part 6255 is accommodated in the groove. For example, the cross-sectional shape of the groove is convex, and the protruding end of the fourth driving part 6255 is accommodated at the bottom of the groove.

[0029] like Figure 5 As shown, the gripper assembly 625 includes a gripper 6251 and a fourth drive unit 6255 for driving the gripper assembly 625 to slide along the slide rail pair 622. One end of the fourth drive unit 6255 is fixedly mounted on the gripper 6251. For example, the second ejector device is a pneumatic cylinder or an electric cylinder. The gripper assembly 625 also includes a gripper mounting base 6256, which is fixedly connected to the slider of the slide rail pair 622. The gripper 6251 is fixedly mounted on the gripper mounting base 6256.

[0030] Preferably, the gripper mounting base 6256 includes a first mounting portion fixedly mounted on the slider of the slide rail pair 622 and a second mounting portion perpendicular to the first mounting portion. A through hole is formed in the second mounting portion. The other end of the fourth driving portion 6255 is fixedly mounted on the second mounting portion, and the protruding end of the fourth driving portion 6255 passes through the through hole and is accommodated in a groove. To increase the rigidity and strength of the gripper mounting base 6256, the gripper mounting base 6256 further includes a third mounting portion disposed on the sidewalls of the first and second mounting portions, used to enhance the rigidity and strength of the gripper mounting base 6256, making the gripper mounting base 6256 more stable.

[0031] like Figure 5As shown, the gripper 6251 includes a connecting arm 6252 fixedly mounted on the gripper mounting base 6256, a first clamping arm 6253 and a second clamping arm 6254 fixedly mounted on the connecting arm 6252, and the first clamping arm 6253 and the second clamping arm 6254 are spaced apart to form a clamping space.

[0032] Since the outer wall of the flat wire stator winding 606 is cylindrical, the extended ends of both the first clamping arm 6253 and the second clamping arm 6254 are provided with inclined clamping surfaces to facilitate clamping the flat wire stator winding 606. For example, the clamping surfaces are inclined arc-shaped surfaces, and the inclination angle and curvature of the clamping surfaces are adapted to the outer wall of the flat wire stator winding 606. The two clamping surfaces are arranged opposite to each other, and during operation, the clamping surfaces abut against the outer wall of the flat wire stator winding 606 to clamp the flat wire stator winding 606.

[0033] Continue to refer to Figure 5 In one embodiment, the connecting arm 6252 is stepped and is also provided with reinforcing ribs. The reinforcing ribs are provided on the side opposite to the first clamping arm 6253 and the second clamping arm 6254. The reinforcing ribs can enhance the rigidity and strength of the connecting arm 6252, making the overall structure of the gripper 6251 more stable.

[0034] In one embodiment, the connecting arm 6252 is L-shaped, the bottom of the connecting arm 6252 is fixedly mounted on the gripper mounting base 6256, and the top of the connecting arm 6252 is provided with a first clamping arm 6253 and a second clamping arm 6254 at intervals.

[0035] like Figure 3 or Figure 4 As shown, the gripping and flipping device 602 also includes an electric slip ring 64, which is fixedly connected to the third drive unit 61 and is disposed on the side away from the connecting mechanism 63.

[0036] When the third drive unit 61 drives the gripper mechanism 62 to rotate, the cable or air pipe of the fourth drive unit 6255 will twist and deform as the gripper mechanism 62 rotates. With long-term use, the cable or air pipe will be damaged due to continuous twisting and deformation. Therefore, an electric slip ring 64 is provided to prevent the cable or air pipe of the fourth drive unit 6255 from being twisted and deformed and damaged as the gripper mechanism 62 rotates.

[0037] like Figure 4As shown, the connection structure includes a rotating shaft, a coupling 631 connecting the output end of the third drive unit 61 and the rotating shaft, and a second mounting plate 632 fixedly mounted on the other end of the rotating shaft. The second mounting plate 632 is fixedly connected to the first mounting plate 621. The connection mechanism 63 also includes a bearing sleeved on the rotating shaft, a connecting flange 633 sleeved on the bearing, and an outer cover 634. The top of the outer cover 634 is fixedly connected to the third drive unit 61, and the bottom of the outer cover 634 is fixedly connected to the connecting flange 633.

[0038] like Figure 6 or Figure 7 As shown, the flattening device 603 includes a fixed base 65, a fifth drive unit 66 fixedly mounted on the fixed base 65, a first washer ring 671 and a second washer ring 672 fixedly mounted on the fixed base 65, a rotating ring 673, a guide ring 674, a cutter assembly 677, a guide assembly 678, a third washer ring 675 disposed in the inner ring of the rotating ring 673, a fixed blade disc 676 disposed on the upper part of the third washer ring 675, and a positioning assembly 679 disposed inside the third washer ring 675.

[0039] To facilitate the installation and positioning of the first washer 671 and the second washer 672 of the fixing base 65, a first annular groove and a second annular groove are formed on the upper surface of the fixing base 65. The second annular groove is located inside the first annular groove, and the first annular groove and the second annular groove are spaced apart. The first washer 671 is accommodated in the first annular groove, and the second washer 672 is accommodated in the second annular groove.

[0040] like Figure 8 As shown, a first groove 6711 is formed on the first washer 671. (As indicated...) Figure 7 As shown, the rotating ring 673 is disposed on the upper part of the second washer ring 672. To facilitate the rotation of the rotating ring 673, the outer sidewall of the rotating ring 673 does not contact the inner sidewall of the first washer ring 671. Figure 9 As shown, the rotating ring 673 includes a first connecting portion 6731, which protrudes from the ring body of the rotating ring 673. The first connecting portion 6731 is accommodated within a first groove 6711. The first connecting portion 6731 is fixedly connected to a fifth driving portion 66, which can achieve forward and reverse rotation. The fifth driving portion 66 can drive the first connecting portion 6731 to reciprocate within the first groove 6711. The effective stroke of the first connecting portion 6731 within the first groove 6711 limits the effective stroke of the cutter assembly 677.

[0041] Continue to refer to Figure 9Along the circumference of the rotating ring 673, N first waist-shaped grooves 6732 are formed, and the N first waist-shaped grooves 6732 are evenly distributed, where N is a positive integer greater than or equal to 2. Preferably, the first waist-shaped grooves 6732 are arc-shaped waist-shaped grooves, and the first waist-shaped grooves 6732 are set along a preset angle direction, the preset angle being related to the operating stroke of the rotating ring 673.

[0042] like Figure 10 As shown, a guide ring 674 is positioned above a rotating ring 673, and its inner ring is fixedly connected to a third washer ring 675. N second grooves 6741 are formed radially along the guide ring 674. These second grooves 6741 are through-hole grooves, connecting the inner and outer rings of the guide ring 674. The N second grooves 6741 are evenly distributed circumferentially along the guide ring 674. Within each second groove 6741, N second waist-shaped grooves 6742 are formed along its length. These second waist-shaped grooves 6742 are straight waist-shaped grooves, and their length direction is the same as the extension direction of the second groove 6741.

[0043] The guide assembly 678 is disposed in the first waist-shaped groove 6732 and the second waist-shaped groove 6742, and the cutter assembly 677 is disposed in the second groove 6741. The guide assembly 678 is fixedly connected to the cutter assembly 677. The cutter assembly 677 can move in the second groove 6741 under the drive of the fifth drive unit 66.

[0044] When the fifth drive unit 66 drives the rotating ring 673 to rotate, it can drive the guide component 678 set in the first waist-shaped groove 6732 and the second waist-shaped groove 6742 to move, and then drive the cutter component 677 to move in the second groove 6741. When the cutter moves to the inner ring of the guide ring 674, it can cut the flat wire inserted in the fixed cutter disc 676 flat. After the flattening process is completed, the fifth drive unit 66 flips over and drives the cutter component 677 to move to the outer ring of the guide ring 674 to prepare for the next flattening process.

[0045] like Figure 6As shown, the fifth drive unit 66 includes a drive unit 661 fixedly mounted on a fixed base 65, a first gear 662 fixedly connected to the output end of the drive unit 661, and a second gear 663 meshing with the first gear 662. Preferably, the drive unit 661 includes a motor and a reducer connected to the output end of the motor. The drive unit 661 is fixedly mounted on the bottom of the fixed base 65, and a mounting hole is provided on the fixed base 65. The output end of the drive unit 661 passes through the mounting hole. The first gear 662 is fixedly mounted on the output end of the drive unit 661, and the second gear 663 is located on one side of the first gear 662, meshing with the first gear 662. Preferably, the second gear 663 is part of the entire gear, and a fourth groove 664 is provided on the second gear 663. The first connecting part 6731 of the rotating ring 673 is fixedly mounted in the fourth groove 664. The output end of the drive unit 661 drives the first gear 662 to rotate, the first gear 662 drives the second gear 663 to rotate, and the second gear 663 drives the rotating ring 673 to rotate. The forward and reverse rotation of the drive unit 661 can realize the reciprocating motion of the rotating ring 673 within the first groove 6711.

[0046] like Figure 11 As shown, N third grooves 6751 are formed along the radial direction of the third washer ring 675, and the N third grooves 6751 are evenly distributed in the circumferential direction of the third washer ring 675. A first step 6752 is also provided on the outer ring of the third washer ring 675, and a guide ring 674 is provided on the first step 6752. Preferably, the guide ring 674 and the first step 6752 are connected by fasteners, and the first step 6752 is used to install and position the guide ring 674.

[0047] like Figure 12 As shown, the cutter assembly 677 includes a cutter bar 6771 disposed within a second groove 6741 and a cutter portion 6772 fixedly disposed at one end of the cutter bar 6771. To facilitate the installation and positioning of the cutter bar 6771 and the cutter portion 6772, preferably, a second step is provided at the front end of the cutter bar 6771, and a third step is provided on the cutter portion 6772. Mounting holes are respectively provided on the second and third steps, which cooperate to position and install the cutter portion 6772.

[0048] When the fifth drive unit 66 drives the cutter assembly 677 to move toward the inner ring of the guide ring 674, the cutter part 6772 can be accommodated in the third groove 6751 to cut the flat wire inserted on the fixed cutter disc 676.

[0049] like Figure 13As shown, N groups of flat cutting slots 6761 are formed along the radial direction of the fixed cutter head 676, and the N groups of flat cutting slots 6761 are evenly distributed in the circumferential direction of the fixed cutter head 676. The group of flat cutting slots 6761 includes M flat cutting slots arranged along the radial direction of 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, that is, the group of flat cutting slots 6761 includes 4 flat cutting slots arranged along the radial direction of the fixed cutter head 676, in which case 4 layers of flat wire can be inserted.

[0050] like Figure 7 As shown, the positioning assembly 679 includes a first positioning part 6791 fixedly mounted on the fixed base 65, a second positioning part 6792 sleeved outside the first positioning part 6791, and a third positioning part 6793. The top of the second positioning part 6792 is fixedly connected to the bottom of the fixed tool disc 676. To facilitate the installation and positioning of the fixed tool disc 676, a fourth step is provided on the top of the second positioning part 6792. The bottom of the fixed tool disc 676 and the top of the fourth step cooperate with each other to facilitate the installation and positioning of the fixed tool disc 676. The third positioning part 6793 is threadedly connected to the fixed seat 65. For example, the outer peripheral surface of the third positioning part 6793 is provided with threads, and the center of the fixed seat 65 is provided with a threaded hole. The top end of the third positioning part 6793 extends out of the fixed seat 65 through the threaded hole, and the top end of the third positioning part 6793 abuts against the bottom of the first positioning part 6791. The first positioning part 6791 is used to position and limit the positioning and fixing device 605. By adjusting the length of the third positioning part 6793 extending out of the fixed seat 65, the distance between the first positioning part 6791 and the fixed seat 65 can be adjusted, thereby making the positioning and fixing device 605 compatible with the cutting and flattening device 603.

[0051] like Figure 14 As shown and referenced Figure 7 The guide assembly 678 includes a guide portion 6781 housed in a second oblong groove 6742 and a rolling portion 6782 housed in a first oblong groove 6732. The upper end of the rolling portion 6782 is fixedly connected to the guide portion 6781. For example, the rolling portion 6782 is a screw, threadedly connected to the guide portion 6781, and its bottom is cylindrical to facilitate rolling within the first oblong groove 6732. Alternatively, the rolling portion 6782 can be a roller, connected to the guide portion 6781 via a threaded shaft.

[0052] like Figure 6 or Figure 7 As shown, the cutting device 603 also includes a retaining ring 680, which is fixedly disposed above the guide ring 674. The bottom wall of the retaining ring 680 abuts against the top of the cutter assembly 677. The retaining ring 680 is used to restrict the movement of the cutter assembly 677 in the height direction and prevent the cutter assembly 677 from coming out of the second groove 6741.

[0053] like Figure 15 As shown, the flat wire stator winding flattening system also includes a wire pressing device 604, which is fixedly connected to the conveying device 601. The wire pressing device 604 is used to prevent the flat wire of the flat wire stator from exceeding a preset height. Preferably, the wire pressing device 604 is located above the clamping and flipping device 602, and the conveying device 601 can drive the wire pressing device 604 to move in both horizontal and vertical directions. When the clamping and flipping device 602 clamps the flat wire stator winding and places it on the flattening device 603, the flat wire inserted in the stator may move upward, resulting in an uneven flat wire. To prevent the flat wire from moving, after the clamping and flipping device 602 clamps the flat wire stator winding, the wire pressing device 604 descends vertically to press the flat wire, ensuring that when the clamping and flipping device 602 places the flat wire stator winding on the flattening device 603, the flat wire will not exceed the preset height, keeping the flat wire at the same height.

[0054] Continue to refer to Figure 15 The wire pressing device 604 includes a first support 6041, a sixth drive unit 6042, a guide mechanism 6043, and a wire pressing part 6047. The first support 6041 is fixedly mounted on the conveying device 601; preferably, the first support 6041 is fixed on the second vertical beam of the second conveying mechanism. Under the drive of the first drive unit and the second drive unit, the wire pressing device 604 can achieve horizontal and vertical movement, respectively.

[0055] The sixth drive unit 6042 is fixedly mounted on the first support 6041, and its output end is fixedly connected to the top of the wire pressing part 6047. Preferably, the sixth drive unit 6042 can be a cylinder or an electric cylinder, the wire pressing part 6047 is disc-shaped, and its output end is fixedly connected to the top of the wire pressing part 6047 via a connecting flange. The sixth drive unit 6042 can drive the wire pressing part 6047 to move along the extension direction of the sixth drive unit 6042.

[0056] The guiding mechanism 6043 includes a guide shaft 6044, a first flange 6045 sleeved on the guide shaft 6044, and a first bushing 6046 disposed on the top of the first flange 6045. The guide shaft 6044 passes through a first support 6041, and the bottom of the guide shaft 6044 is fixedly connected to the top of the crimping part 6047. The first flange 6045 is fixedly connected to the first support 6041. Preferably, the first flange 6045 is fixedly disposed on the first support 6041. The guiding mechanism 6043 is used to guide the movement of the crimping part 6047. Preferably, there are two guiding mechanisms 6043, respectively disposed on both sides of the sixth drive part 6042, for guiding the movement of the crimping part 6047, so as to make the movement of the crimping part 6047 smoother and prevent the crimping part 6047 from deviating during the movement.

[0057] To facilitate the fixing and positioning of the flat wire stator winding 606, the flat wire stator winding flattening system 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 onto the positioning and fixing device 605 to achieve pre-fixing and pre-positioning of the flat wire stator winding 606.

[0058] like Figures 16 to 21 As shown, the positioning and fixing device includes a first fixing ring 6051, a second fixing ring 6052, a connecting ring 6054 fixedly connected to the bottom of the first fixing ring 6051, a first fixing ring 6055 fixedly connected to the bottom of the second fixing ring 6052, a second fixing ring 6056 disposed at the bottom of the first fixing ring 6055, a third fixing ring 6058 disposed at the bottom of the second fixing ring 6056 and fixedly connected to the first fixing ring 6055, a fourth fixing ring 6057 snapped into the second fixing ring 6056 and fixedly connected to the first fixing ring 6055, a positioning ring 6059 fixedly connected to the first fixing ring 6055, and an adjusting component 6053.

[0059] like Figure 21 As shown, two second connecting parts are symmetrically arranged on the outer ring of the first fixing ring 6051. Each of the two second connecting parts has a mounting hole. Preferably, the size of the mounting hole is larger than the size of the connecting block. Figure 1 or Figure 2 As shown, the connecting block is fitted into the mounting hole and is fixedly connected to the second fixing ring 6052. The second connecting part is rotatably connected to the adjusting component 6053. When the adjusting component 6053 adjusts the rotation of the second fixing ring 6056, the adjusting component 6053 rotates with the connection point between the second connecting part and the adjusting component 6053 as the fulcrum.

[0060] Continue to refer to Figure 21 A first recessed portion is provided on the outer ring of the first fixing ring 6051. For example... Figure 4 As shown, the outer diameter of the connecting ring 6054 is larger than the outer ring size of the first concave portion, and the outer ring of the connecting ring 6054 and the first concave portion form an inner groove.

[0061] like Figure 20 As shown, a protrusion is provided on the inner ring of the second fixing ring 6052, and the protrusion is accommodated in the inner groove; the protrusion and the inner groove cooperate with each other to install and position the second fixing ring 6052. Two fourth inner recesses are symmetrically provided on the second fixing ring 6052, and the two second connecting parts are respectively accommodated in the two fourth inner recesses.

[0062] like Figure 21 As shown, 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.

[0063] A second recess is provided on the inner ring of the third fixing ring 6058. Two third recesses are also symmetrically provided on the third fixing ring 6058. The two third recesses communicate with the second recess 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 recess, and the two fourth connecting parts are respectively received in the two third recesses.

[0064] like Figure 18 As shown, the third fixing ring 6058 is provided with a scale to indicate the distance the second fixing ring 6056 has moved.

[0065] like Figure 21 As shown and referenced Figure 20 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.

[0066] Continue to refer to Figure 21N 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.

[0067] 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.

[0068] The outer ring of the fourth fixing ring 6057 is provided with a first step portion, and the inner ring of the second 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 fixing ring 6056.

[0069] like Figure 22 As shown, 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.

[0070] 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.

[0071] like Figure 23 As shown, the adjusting assembly 6053 also includes a spring sleeved on the connecting rod, and the connecting rod is provided with a blocking part, with the spring located between the blocking part and the sliding part.

[0072] 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.

[0073] The flat wire stator winding flattening system of this application operates 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, the flat wire stator winding 606 stops moving. The conveying device 601 drives the clamping and flipping device 602 and the wire pressing 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 fourth drive unit 6255 drives the jaw assembly 625 to move relative to each other, and the two jaw assemblies 625 clamp the flat wire stator winding 606. Then, the conveying device 601 drives the clamping and flipping device 602 and the wire pressing device 604 to move vertically upwards to the first preset position. After the position is determined, the third drive unit 61 drives the gripping and flipping device 602 to rotate 180°. The conveying device 601 then moves the gripping and flipping device 602 and the wire pressing device 604 to the preset position. After that, the fourth drive unit 6255 drives the gripper assembly 625 to move towards each other. The two gripper assemblies 625 release the flat wire stator winding 606. At this time, the flat wire stator winding 606 is rotated 180° and placed on the preset position. Then, the conveying device 601 moves the gripping and flipping device 602 and the wire pressing device 604 upward to the second preset position.

[0074] 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 pressing 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 pressing device 604 to move above the flattening device 603. The clamping and flipping device 602 drives the flat wire stator winding 606 to rotate 180°. Then, the sixth drive unit of the wire pressing device 604 drives the wire pressing part to extend, and the wire pressing part 6047 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 wire pressing device 604 to descend, placing the flat wire stator winding 606 and the positioning and fixing device 605 on the flattening 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 wire pressing device 604 to rise to the third preset position.

[0075] The fifth drive unit 66 drives the cutter assembly 677 towards the center of the flat wire stator winding 606, cutting the flat wire of the flat wire stator winding 606 flat. Then, the fifth drive unit 66 reverses direction, 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 pressing device 604 to descend. The clamping and turning device 602 clamps the flat wire stator winding 606 and conveys it onto the pallet. The conveying device 601 then drives the clamping and turning device 602 and the pressing device 604 back to their initial positions. The flat wire stator winding 606 continues to move along the roller conveyor to the next process under the drive of the pallet.
