[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work 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 material discharge assembly, the top of which is inclined up and down and the flat copper wire moves from a high position to a low position of the material discharge assembly;

[0046] An upper pressing assembly 1, wherein the upper pressing assembly 1 is located above the lowering assembly and can be raised and lowered;

[0047] A first span adjustment component 7, which is disposed below the top of the blanking component and can adjust the span according to the spans of the two 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, and the predetermined interval is set independently and can be 0, or 1 cm or other different intervals;

[0048] A wire pushing assembly 2, which is arranged at one end of the blanking assembly located at a lower position, and is used to drop the U-shaped flat copper wires on the blanking assembly one by one;

[0049] The grabbing assembly is arranged on the side of the pushing assembly away from the unloading assembly, and the grabbing assembly can grab the U-shaped flat copper wires that have fallen off the line one by one and rotate the U-shaped copper wires to be placed horizontally;

[0050] When in use, the U-shaped flat copper wire slides onto the blanking component, and the upper pressing component 1 is controlled to move downward according to the height of the crown end of the U-shaped flat copper wire. By adjusting the interval between the blanking component and the upper pressing component 1, the U-shaped flat copper wire is prevented from continuously sliding into the blanking component, thereby avoiding the problem of accumulation. The U-shaped flat copper wires on the blanking component are dropped one by one through the wire pushing component 2, and then the grabbing component grabs the U-shaped flat copper wire and rotates it to a horizontal state to facilitate subsequent processing.

[0051] In this embodiment, a bottom plate 12 is also included, a front support plate 11 and a rear support plate 10 are arranged on the top of the bottom plate 12, and a diagonal support plate 13 is fixedly connected to the front support plate 11 and the rear support plate 10. Two upper limit support plates 15 are evenly distributed on both sides of the top of the diagonal support plate 13 along the inclined direction. The blanking assembly and the first span adjustment assembly 7 are both located on the diagonal support plate 13, and the upper pressing assembly 1 is installed on the upper limit support plate 15;

[0052] When in use, the blanking assembly is placed in an inclined state by means of the diagonal support plate 13 to ensure the blanking of the U-shaped flat copper wire.

[0053] In this embodiment, the blanking assembly includes two intermediate vertical plates 14 arranged along the inclined direction of the diagonal support plate 13 and fixed on the top of the diagonal support plate 13, a mounting bar 161 is fixed on the top of the two intermediate vertical plates 14, a wire support bar 16 is installed on the mounting bar 161, a vibration assembly is fixed at the bottom of the wire support bar 16, and the vibration assembly is a pneumatic vibrator 18, and the wire pushing assembly 2 is arranged on the wire support bar 16;

[0054] When in use, the U-shaped flat copper wire falls onto the wire support bar 16 , and 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 unloading 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 mounted 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 respectively 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, and a guide block 106 is fixedly mounted on one end of the upper pressure plate 105 located at a high position;

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

[0057] In this example, the first span adjustment assembly 7 includes two first slide rails 77, two connecting sliders 74, two first main guide strips 73 and a first servo reduction motor 76. The two first slide rails 77 are evenly distributed and fixed on the top of the diagonal support plate 13 along the inclination direction of the diagonal support plate 13, and the sliding direction of the first slide rails 77 is perpendicular to the inclination direction of the diagonal support plate 13. Both ends of the two connecting sliders 74 are slidably connected to the two first slide rails 77, and a plurality of evenly distributed guide mounting plates 75 are fixedly installed on the two connecting sliders 74. The first main guide strips 73 are fixed to a plurality of guide mounting plates 75 on the same connecting slider 74. On the mounting plate 75, a plurality of evenly distributed connecting plates 72 are fixedly installed above the two first main guide bars 73, and 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 diagonal support plate 13, and the output end of the first servo reduction motor 76 extends to the top of the diagonal support plate 13 and is connected to a first rotating arm 79, and 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, and 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 the adjustment, the first servo reduction motor 76 drives the first rotating arm 79 to rotate in the forward and reverse directions, and under the cooperation of the first connecting rod 70 and the hinge pin 701, the two connecting sliders 74 are pushed to move closer to or farther from each other along the first slide rail 77, thereby achieving the two first main guide bars 73 and the two second main guide bars 71 to move closer to or farther from each other to match the span of the copper wire, so that the copper wire can slide steadily from the high position of the wire support bar 16 to the low position;

[0059] Preferably, an end stopper 78 is provided at the end of the first main guide bar 73 to stabilize the sliding U-shaped flat copper wire at the end of the first main guide bar 73 for easy removal.

[0060] In this embodiment, the wire pushing 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 wire pushing shaft 27, a follower mounting block 26 arranged on one side of the wire pushing shaft 27, a first follower 28 fixed on the follower mounting block 26, a wire pushing seat 21 fixedly mounted at the end of the mounting bar 161, a lower sliding support block 203, a second follower 201 fixed on both sides of the lower sliding support block 203, an end sliding block 23 and a tail end support block 22, and the output end of the second cylinder 24 extends to the bottom of the cylinder mounting plate 25 and is fixedly connected to the wire pushing shaft 27;

[0061] The first follower 28 contacts the side wall of the wire pushing shaft 27, a through slot 20 is provided on the wire pushing seat 21, and inclined slots 202 are provided on the symmetrical sides of the wire pushing seat 21, and the two inclined slots 202 are connected with the through slot 20, and the second follower 201 is respectively placed in the two inclined slots 202, and the lower slide support block 203 is slidably connected in the through slot 20 and a return spring 204 connected to the lower slide support block 203 is provided in the through slot, the terminal slide block 23 is fixedly installed at the end of the mounting strip 161 and contacts the side wall of the wire pushing seat 21, and the tail end support block 22 is fixedly installed at the end of the terminal slide block 23 away from the wire pushing seat 21;

[0062] The wire pushing shaft is provided with a placement groove for placing the U-shaped flat copper wire, wherein only one U-shaped flat copper wire can be placed in the placement groove, so that the U-shaped flat copper wires can be unloaded one by one;

[0063] During use, since the crown ends of U-shaped flat copper wires of different specifications have different heights, during adjustment, the second cylinder 24 pushes the wire pushing shaft 27 downward. During use, the first follower 28 supports the wire pushing shaft 27 to prevent the wire pushing shaft 27 from being squeezed and deformed by more and more copper wires.

[0064] In the initial state, the downward sliding support block 203 is in close contact with the wire pushing shaft 27, and then the U-shaped flat copper wire slides into the placement groove, the wire pushing shaft 27 moves downward and pushes the downward sliding support block 203 to move, and the downward 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 wire block 23, and then the wire pushing 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 placement groove, when the wire pushing shaft moves downward, the remaining U-shaped flat copper wires will not fall due to the limit of the wire pushing shaft.

[0066] In this embodiment, the grabbing assembly includes a material moving support assembly 8 symmetrically arranged on the bottom plate 12, a rotating clamping assembly 5 arranged on the material moving support assembly 8, a second span adjusting assembly 6 for adjusting the span of the rotating clamping assembly 5, and a driving assembly 4 for driving the rotating clamping assembly 5. A follower clamping assembly 3 is arranged on the top of the material moving support assembly 8, and the span of the follower clamping assembly 3 changes with the span of the rotating clamping assembly 5.

[0067] The material moving support assembly 8 includes two material moving support plates 82 symmetrically arranged on the top of the base plate 12, and the material moving support plates 82 are located on one side of the unloading mechanism, a motor mounting plate 85 is arranged on one side of the two material moving support plates 82, a slide rail mounting plate 83 is fixedly installed between the two material moving support plates 82, a second slide rail 81 is fixedly installed on the top of the slide rail mounting plate 83, and 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 moving support assembly 8, two rotating arms 51 symmetrically sleeved on the spline shaft 53 and plugged with the spline shaft 53, a first clamping jaw cylinder 52, a clamping jaw 1 506 and a clamping jaw 2 505 arranged at the end of the rotating arm 51, the spline shaft 53 is rotatably arranged between the two material moving support plates 82 and is located above the slide rail mounting plate 83, the output end of the first clamping jaw cylinder 52 is fixedly connected to the clamping jaw 1 506 and the clamping jaw 2 505 respectively, and the driving assembly 4 can drive the spline shaft 53;

[0069] The two rotating arms 51 are sleeved on the ends of the spline shaft 53, and thrust ball bearings 57 are fixedly arranged on the opposite sides thereof. The rotation center of the thrust ball bearing 57 is arranged concentrically with the rotation axis of the spline shaft 53. The two sides of the rotating arms 51 are fixedly connected to the limit plates 54 through the thrust ball bearings 57. The limit plates 54 are independently fixedly connected to the sliding connection plates 84. The two sliding connection plates 84 are connected to the second span adjustment assembly 6 to adjust the span between the two rotating arms 51.

[0070] The two sliding connecting plates 84 are fixedly connected to a fixed block 55 on one side close to the unloading mechanism. A hydraulic buffer 56 is fixedly mounted on the two fixed blocks 55 . The upper end of the hydraulic buffer 56 extends upward from the fixed block 55 . The hydraulic buffer 56 is located below the rotating arm 51 .

[0071] When in use, according to different specifications of the U-shaped flat copper wire, the second span adjustment component 6 is used to drive the sliding connecting plate 84 to move relative or oppositely, and then the sliding connecting plate 84 drives the rotating arm 51 to adjust through the thrust ball bearing 57. After the adjustment is completed, the first clamping jaw cylinder 52 clamps the U-shaped flat copper wire through the clamping jaw 1 506 and the clamping jaw 2 505, and then the driving 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 clamping component 3. After the follower clamping component 3 clamps the U-shaped flat copper wire, the driving mechanism drives the rotating arm 51 to reset, and the first clamping jaw cylinder 52 clamps the U-shaped flat copper wire again through the clamping jaw 1 506 and the clamping jaw 2 505;

[0072] When the rotating arm 51 rotates and resets, the hydraulic buffer 56 contacts the rotating arm 51 or the first clamping jaw cylinder 52 to achieve buffering;

[0073] The spline shaft 53 is sleeved with an external spline 58, which is embedded in the inside of 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 which is embedded in the inner side of the rotating arm 51. When the span is changed, under the action of the external spline 58, the rotating arm 51 can move along both sides of the axial extension end of the spline shaft 53, and at the same time, it can also ensure that the spline shaft 53 can drive the rotating arm 51 to rotate;

[0074] The two rotating arms 51 are inserted through and sleeved on the guide shaft 501, and are slidably connected to the guide shaft 501. The two ends of the guide shaft 501 are respectively fixedly connected with guide shaft mounting blocks 503. The two guide shaft mounting blocks 503 are both fixedly provided with spring connecting columns 504. The spring hooks 20 are respectively fixedly installed on the opposite sides of the two rotating arms 51.

[0075] The spring hook 20 and the spring connecting column 504 which are arranged opposite to each other are connected by a spring 502.
