[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] like Figure 1-14 As shown, a flat copper wire rack for stator production includes:

[0045] A feeding assembly, wherein the top of the feeding assembly is tilted vertically and the flat copper wire moves from the high point of the feeding assembly to the low point;

[0046] The upper pressure component 1 is located above the unloading component and is adjustable in height.

[0047] The first span adjustment component 7 is located below the top of the feeding component and can adjust the span according to the span at both ends of the U-shaped flat copper wire so that the U-shaped flat copper wire is always kept at a predetermined interval with the side of the first span adjustment component 7. The predetermined interval is set by the user and can be 0 or 1cm or other different intervals.

[0048] The pusher assembly 2 is located at the lower end of the unloading assembly and is used to remove the U-shaped flat copper wires one by one from the unloading assembly.

[0049] The gripping component is located on the side of the pushing component away from the unloading component, and the gripping component can grip the dropped U-shaped flat copper wires one by one and rotate the U-shaped copper wires to a horizontal position.

[0050] During use, the U-shaped flat copper wire slides into the feeding assembly. The upper pressure assembly 1 is moved down according to the height of the crown end of the U-shaped flat copper wire. By adjusting the interval between the feeding assembly and the upper pressure assembly 1, the U-shaped flat copper wire is prevented from continuously sliding into the feeding assembly, thus avoiding the problem of accumulation. The U-shaped flat copper wires on the feeding assembly are dropped off one by one by the wire pushing assembly 2. Then, the gripping assembly grips the U-shaped flat copper wires and rotates them to a horizontal state for easy subsequent processing.

[0051] In this embodiment, a base plate 12 is also included. A front support plate 11 and a rear support plate 10 of different heights are provided on the top of the base plate 12. A diagonal brace 13 is fixedly connected to both the front support plate 11 and the rear support plate 10. Two evenly distributed upper limit support plates 15 are provided on both sides of the top of the diagonal brace 13 along the inclined direction. The feeding component and the first span adjustment component 7 are both located on the diagonal brace 13. The upper pressing component 1 is installed on the upper limit support plate 15.

[0052] During use, the inclined support plate 13 keeps the feeding assembly in an inclined state to ensure the feeding of the U-shaped flat copper wire.

[0053] In this embodiment, the feeding assembly includes two intermediate upright plates 14 that are arranged along the inclined direction of the inclined support plate 13 and fixed to the top of the inclined support plate 13. An installation strip 161 is fixed to the top of the two intermediate upright plates 14. A line support strip 16 is installed on the installation strip 161. A vibration assembly is fixed to the bottom of the line support strip 16. The vibration assembly is a pneumatic vibrator 18. The line pushing assembly 2 is arranged on the line support strip 16.

[0054] During use, the U-shaped flat copper wire falls onto the wire support bar 16. Under the action of the pneumatic vibrator 18, the U-shaped flat copper wire slides down along the wire support bar 16, thereby realizing the feeding of the U-shaped flat copper wire.

[0055] In this example, the upper pressure assembly 1 includes a front connecting plate 101, a rear connecting plate 102, two first cylinders 103 respectively fixed on the front connecting plate 101 and the rear connecting plate 102, two connecting blocks 104, and an upper pressure plate 105. The front connecting plate 101 and the rear connecting plate 102 are respectively fixedly installed on the top of two upper limit support plates 15. The output shafts of the two first cylinders 103 extend to the bottom of the front connecting plate 101 and the rear connecting plate 102 and are fixed to the connecting blocks 104. The two connecting blocks 104 are connected to the top of the same upper pressure plate 105. A guide block 106 is fixedly installed at the higher end of the upper pressure plate 105.

[0056] During use, the distance between the upper pressure plate 105 and the wire support bar 16 is adjusted according to the height of the copper wire crown end. The first cylinder 103 presses the upper pressure plate 105 down to a certain position to avoid the problem of accumulation caused by the copper wire continuously sliding into the wire support bar 16. The guide block 106 facilitates the copper wire sliding into the wire support bar 16.

[0057] In this embodiment, the first span adjustment assembly 7 includes two first slide rails 77, two connecting sliders 74, two first main guide bars 73, and a first servo reduction motor 76. The two first slide rails 77 are evenly distributed and fixed on the top of the inclined support plate 13 along the inclination direction of the inclined support plate 13, and the sliding direction of the first slide rails 77 is perpendicular to the inclination direction of the inclined support plate 13. The two ends of the two connecting sliders 74 are respectively slidably connected to the two first slide rails 77. Multiple evenly distributed guide mounting plates 75 are fixedly installed on each of the two connecting sliders 74. The first main guide bars 73 are fixed to multiple guides on the same connecting slider 74. On the mounting plate 75, multiple evenly distributed connecting plates 72 are fixedly installed above the two first main guide bars 73. A second main guide bar 71 is fixedly connected to the connecting plate 72 on the same first main guide bar 73. The first servo reduction motor 76 is fixedly installed at the bottom of the inclined support plate 13. The output end of the first servo reduction motor 76 extends to the top of the inclined support plate 13 and is connected to the first rotating arm 79. Two symmetrically distributed first connecting rods 70 are rotatably connected to the first rotating arm 79. A hinge pin 701 is provided through the middle of the two connecting sliders 74. The two first connecting rods 70 are respectively hinged to the two hinge pins 701.

[0058] When in use, the span between the two first main guide bars 73 and the two second main guide bars 71 needs to be adjusted for copper wires of different specifications. During adjustment, the first servo reduction motor 76 drives the first rotating arm 79 to rotate in both directions. With the cooperation of the first connecting rod 70 and the hinge pin 701, the two connecting sliders 74 are pushed to move closer or further away from each other along the first slide rail 77, thereby making the two first main guide bars 73 and the two second main guide bars 71 move closer or further away from each other to match the copper wire span, so that the copper wire can slide stably from the high point of the wire support bar 16 to the low point.

[0059] Preferably, the end of the first main guide bar 73 is provided with an end limiting block 78 to stabilize the sliding U-shaped flat copper wire at the end of the first main guide bar 73 so that it can be removed.

[0060] In this embodiment, the push wire assembly 2 includes a cylinder mounting plate 25 fixed to the bottom of the rear connecting plate 102 by two pads 29, a second cylinder 24 fixed on the cylinder mounting plate 25, a push wire shaft 27, a follower mounting block 26 disposed on one side of the push wire shaft 27, a first follower 28 fixed on the follower mounting block 26, a push wire seat 21 fixedly installed at the end of the mounting strip 161, a sliding support block 203, a second follower 201 fixed on both sides of the sliding support block 203, an end sliding block 23 and a tail end support block 22. The output end of the second cylinder 24 extends to the bottom of the cylinder mounting plate 25 and is fixedly connected to the push wire shaft 27.

[0061] The first follower 28 contacts the side wall of the pusher shaft 27. The pusher seat 21 has a through groove 20. The pusher seat 21 has inclined grooves 202 through its two symmetrical sides. The two inclined grooves 202 are connected to the through groove 20. The second follower 201 is placed in the two inclined grooves 202 respectively. The sliding support block 203 is slidably connected in the through groove 20 and a return spring 204 connected to the sliding support block 203 is provided in the through groove. The end slide block 23 is fixedly installed at the end of the mounting strip 161 and contacts the side wall of the pusher seat 21. The tail support block 22 is fixedly installed at the end of the end slide block 23 away from the pusher seat 21.

[0062] The pusher shaft has a placement groove for placing U-shaped flat copper wires, wherein only one U-shaped flat copper wire can be placed in the placement groove, so as to realize the feeding of U-shaped flat copper wires one by one;

[0063] When in use, since the crown end height of different specifications of U-shaped flat copper wires is different, the second cylinder 24 pushes the push shaft 27 down during adjustment. During use, the first follower 28 supports the push shaft 27 to prevent the push shaft 27 from being squeezed and deformed by the increasing amount of copper wire.

[0064] In the initial state, the sliding support block 203 is in close contact with the pusher shaft 27. Then, the U-shaped flat copper wire slides into the placement groove, the pusher shaft 27 moves down and pushes the sliding support block 203 to move. The sliding support block slides along the inclined groove through the second follower and gradually retracts into the through groove. At this time, the U-shaped flat copper wire falls to the end sliding block 23. Then the pusher shaft is reset, and another U-shaped flat copper wire slides into the placement groove so as to grab and transfer the copper wire.

[0065] Since only one U-shaped flat copper wire can be placed in the slot, the remaining U-shaped flat copper wires will not fall off due to the limit of the push shaft when the push shaft moves down.

[0066] In this embodiment, the gripping component includes a material transfer support component 8 symmetrically arranged on the base plate 12, a rotating clamping component 5 arranged on the material transfer support component 8, a second span adjustment component 6 for adjusting the span of the rotating clamping component 5, and a driving component 4 for driving the rotating clamping component 5. A follow-up clamping component 3 is provided on the top of the material transfer support component 8, and the span of the follow-up clamping component 3 changes with the span of the rotating clamping component 5.

[0067] The material transfer support assembly 8 includes two material transfer support plates 82 symmetrically arranged on the top of the base plate 12, and the material transfer support plates 82 are located on one side of the unloading mechanism. A motor mounting plate 85 is provided on one side of the two material transfer support plates 82. A slide rail mounting plate 83 is fixedly installed between the two material transfer support plates 82. A second slide rail 81 is fixedly installed on the top of the slide rail mounting plate 83. Two symmetrically distributed sliding connecting plates 84 are slidably arranged on the second slide rail 81.

[0068] The rotating clamping assembly includes a spline shaft 53 rotatably connected to the material transfer support assembly 8, two symmetrically sleeved on the spline shaft 53 and inserted into the spline shaft 53, a first gripper cylinder 52, a gripper 1 506 and a gripper 2 505 disposed at the ends of the rotating arms 51. The spline shaft 53 is rotatably disposed between the two material transfer support plates 82 and located above the slide rail mounting plate 83. The output end of the first gripper cylinder 52 is fixedly connected to gripper 1 506 and gripper 2 505 respectively. The driving assembly 4 can drive the spline shaft 53.

[0069] Two rotating arms 51 are sleeved on opposite sides of the ends of the spline shaft 53, and thrust ball bearings 57 are fixedly installed on them respectively. The rotation center of the thrust ball bearings 57 is concentric with the rotation axis of the spline shaft 53. Limiting plates 54 are fixedly connected to both sides of the rotating arms 51 through the thrust ball bearings 57. The limiting plates 54 are independently fixedly connected to the sliding connecting plates 84. The two sliding connecting plates 84 are connected to the second span adjustment assembly 6 to adjust the span between the two rotating arms 51.

[0070] Two sliding connecting plates 84 are fixedly connected to fixed blocks 55 on the side near the feeding mechanism. Hydraulic buffers 56 are fixedly installed on the two fixed blocks 55 respectively. The upper end of the hydraulic buffers 56 extends upward from the fixed blocks 55. The hydraulic buffers 56 are located below the rotating arm 51.

[0071] In use, according to different specifications of U-shaped flat copper wire, the sliding connecting plate 84 is moved relative to or opposite to each other by the second span adjustment component 6. Then, the sliding connecting plate 84 drives the rotating arm 51 to adjust by the thrust ball bearing 57. After the adjustment is completed, the first gripper cylinder 52 clamps the U-shaped flat copper wire by gripper one 506 and gripper two 505. Then, the drive mechanism drives the spline shaft 53 to rotate, and the spline shaft 53 drives the rotating arm 51 to rotate so that the U-shaped flat copper wire rotates to the follower gripper component 3. After the follower gripper component 3 clamps the U-shaped flat copper wire, the drive mechanism drives the rotating arm 51 to reset, and the first gripper cylinder 52 re-clamps the U-shaped flat copper wire by gripper one 506 and gripper two 505.

[0072] When the rotating arm 51 rotates to reset, the hydraulic buffer 56 contacts the rotating arm 51 or the first gripper cylinder 52 to achieve buffering.

[0073] The spline shaft 53 is fitted with an external spline 58, which is fitted inside the rotating arm 51. At the same time, the outer peripheral wall of the external spline 58 is provided with an external spline positioning key 59 that fits into the inner side of the rotating arm 51. When the span is changed, the rotating arm 51 can move along both sides of the axial extension end of the spline shaft 53 under the action of the external spline 58, and at the same time, it can also ensure that the spline shaft 53 can drive the rotating arm 51 to rotate.

[0074] Two rotating arms 51 are sleeved on the guide shaft 501 and slidably connected to the guide shaft 501. Guide shaft mounting blocks 503 are fixedly connected to both ends of the guide shaft 501. Spring connecting columns 504 are fixedly installed on both guide shaft mounting blocks 503. Spring hooks 20 are fixedly installed on opposite sides of the two rotating arms 51.

[0075] The spring hook 20 and the spring connecting post 504 are connected by a spring 502. This arrangement ensures stable adjustment when the span of the rotating arm 51 is adjusted, and at the same time ensures that the rotating arm 51 will not move or shift symmetrically.

[0076] In this embodiment, the follower clamping assembly 3 includes two follower connecting plates 32, two sliding blocks 31, a third slide rail 33, two second gripper cylinders 34, gripper one 506 and gripper two 505. The two follower connecting plates 32 are respectively fixedly installed on the two sliding connecting plates 84. The top of the two material transfer support plates 82 is fixedly installed with the same U-shaped mounting plate 35. The third slide rail 33 is fixedly installed on the top of the U-shaped mounting plate 35. The two sliding blocks 31 are symmetrically slidably arranged on the third slide rail 33. The two second gripper cylinders 34 and the follower connecting plates 32 are respectively fixedly installed on the two sliding blocks 31. The output ends of the second gripper cylinders 34 are respectively fixedly connected to gripper one 506 and gripper two 505.

[0077] When the sliding connecting plate 84 moves relative to or away from each other, the sliding connecting plate 84 drives the second gripper cylinder 34 to move through the follower connecting plate 32 and the sliding block 31. Then, the second gripper cylinder 34 clamps the U-shaped flat copper wire through gripper 1 506 and gripper 2 505.

[0078] In this embodiment, the second span adjustment assembly 6 includes a motor mounting plate, a third servo geared motor 62, a second rotating arm 65, two second connecting rods 64, and two connecting rod fixing blocks 63.
