Description

Technical Field

[0001] This utility model belongs to the field of winding machines, and more specifically, it relates to a generator rotor winding machine. Background Technology

[0002] A new energy vehicle generator refers to a device used in pure electric vehicles or hybrid electric vehicles to recover and generate electricity from the kinetic energy of the vehicle's engine. The generator rotor is the rotating part of the new energy generator, and its structure mainly consists of a rotor core, excitation winding, retaining rings, center ring, fan, slip rings, and leads. The excitation winding, carried by the rotor core, forms a stable magnetic field after being connected to a DC power supply. During rotation, it interacts with the stator winding to generate three-phase alternating current.

[0003] Chinese Patent CN114928223B discloses a motor rotor winding machine, including a frame and a first mounting bracket, etc.; the first mounting bracket is fixed to the middle of the upper surface of the frame. The wound copper wire coils are inspected by a visual detector to determine the number of copper wire coils. If the number of copper wire coils is not up to standard, the hollow rod and the first limiter are driven to unwind the copper wires. At the same time, the unwinding copper wires are pulled straight by two limit blocks, and the copper wires are rewound onto the winding section.

[0004] The aforementioned patent requires manual loading and unloading of materials during the motor rotor winding process, which increases labor costs and reduces the winding efficiency of the generator rotor. Furthermore, after the generator rotor winding is completed, the copper wire is cut with electric shears. At this time, the copper wire end is not bound by external force and is prone to swaying and displacement under its own elasticity, thus affecting the next round of motor rotor winding processing.

[0010] Preferably, the rotary drive assembly includes a wound motor, an eccentric block, and a transmission unit. The eccentric block is rotatably mounted on a connecting shaft, the winding frame is fixedly mounted on one end of the eccentric block, the wound motor is fixedly mounted on a sliding seat, and the wound motor is connected to the eccentric block via the transmission unit, so that the wound motor can drive the eccentric block to rotate around the connecting shaft as a fulcrum via the transmission unit.

[0011] Preferably, the transmission unit includes a driving wheel, a transmission shaft, and a driven wheel. The driving wheel is fixedly mounted on the output shaft of the wound motor. The transmission shaft is rotatably mounted on a sliding seat. A transmission wheel and a drive wheel are fixedly mounted at both ends of the transmission shaft, respectively. The driving wheel and the transmission wheel are connected by a transmission belt. The driven wheel is fixedly mounted on one side of the eccentric block. The drive wheel and the driven wheel are connected by a drive belt.

[0012] Preferably, the wire cutting assembly includes a bracket, which is fixedly installed on a workbench. A limiting frame that can guide and limit the copper wire is fixedly installed on the bracket, and a wire cutting unit that can cut the copper wire passing through the limiting frame is also installed on the bracket.

[0014] This utility model has the following beneficial effects: 1. In this utility model, a conveyor belt is used in conjunction with a generator rotor fixture to transport the generator rotor.

The positioning mechanism and the winding mechanism work together to clamp, position and wind the generator rotor. After the winding is completed, the loading and unloading mechanism transports the generator rotor in the flexible slot into the generator rotor fixture. This enables automatic loading and unloading and automatic winding of the generator rotor, which helps to improve the winding efficiency of the generator rotor. 2. In this utility model, when the generator rotor winding is completed and the copper wire on the limiting frame is cut by the tangent unit, the shearing cylinder simultaneously drives the pressure block and the blade to move towards the limiting frame. Since the pressure block initially extends to the front end of the blade, it can first move onto the limiting frame to press and position the copper wire. Then, the shearing cylinder continues to drive the blade to move downward, causing the blade to cut the copper wire. The pressure block and the telescopic end of the shearing cylinder slide relative to each other, so that the pressure block maintains the pressing state on the copper wire under the elastic force of the spring. At this time, since the pressure block presses and positions the cut copper wire end, it can prevent the copper wire end from shaking or displacing, so that the copper wire end can be wound onto the generator rotor in the next round of generator rotor winding processing.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Please see Figures 1-6 This utility model is a generator rotor winding machine, including a workbench 1, on which a conveyor belt 2, a loading and unloading mechanism 4, a positioning mechanism 5, and a winding mechanism 6 are installed. A generator rotor fixture 3 is placed on the conveyor belt 2. The positioning mechanism 5 includes a left clamping unit, a right clamping unit, and a support shaft 58. The support shaft 58 is rotatably mounted on the workbench 1, and a rotary drive motor connected to the support shaft 58 is installed inside the workbench 1. A flexible slot is provided at the top of the support shaft 58. The loading and unloading mechanism 4 can transport the generator rotor in the generator rotor fixture 3 and insert it into the flexible slot. The winding mechanism 6 includes a rotary drive assembly, a wire cutting assembly, and a winding frame 610. The winding frame 610 is rotatably mounted on the outer ring of the right clamping unit. The front end of the winding frame 610 is provided with a wire hole for copper wire to pass through. The rotary drive assembly can drive the winding frame 610 to make circular motion with the right clamping unit as the fulcrum. The wire cutting assembly can cut the copper wire after winding.

[0022] The generator rotor fixture 3 contains a generator rotor. The generator rotor fixture 3 and the generator rotor are conveyed to the loading / unloading mechanism 4 via the conveyor belt 2. When the generator rotor fixture 3 reaches the loading / unloading mechanism 4, the loading / unloading mechanism 4 inserts the generator rotor from the generator rotor fixture 3 into the flexible slot at the top of the support shaft 58. Then, the left and right clamping units work together to clamp the two sides of the generator rotor. The rotor copper wire for winding passes through the wire limiter of the tangent assembly, passes through the wire hole on the front side of the winding frame 610, and is wound onto the generator rotor. Then, the rotation drive assembly drives the winding frame 610 to clamp the single... The generator rotor is centered on a pivot point and moves in a circular motion, continuously winding copper wire onto the generator rotor. Once the winding in one direction is completed, the left and right clamping units release their grip on the generator rotor. The rotation drive motor drives the support shaft 58 to rotate, thereby causing the generator rotor to rotate in a different direction. The winding process is repeated until the entire winding process of the generator rotor is completed. The copper wire is then cut by the shearing assembly. The loading and unloading mechanism 4 then transports the generator rotor from the flexible slot to the generator rotor fixture 3, thus enabling automatic loading and unloading and automatic winding of the generator rotor, which helps to improve the winding efficiency of the generator rotor.

[0023] Specifically, the loading and unloading mechanism 4 includes a translation slide rail 42, a lead screw 44 is rotatably mounted on one side of the translation slide rail 42, a feeding motor 43 that is connected to the lead screw 44 is fixedly mounted at the end of the translation slide rail 42, a slide plate 45 is slidably mounted on the translation slide rail 42, and the slide plate 45 is threadedly connected to the lead screw 44. A slide rail cylinder 46 is fixedly mounted on the slide plate 45, and a pneumatic gripper 41 is slidably mounted on the slide rail cylinder 46, and the telescopic end of the slide rail cylinder 46 is fixedly connected to the pneumatic gripper 41.

[0024] During loading, the pneumatic gripper 41 is positioned above the generator rotor fixture 3. At this time, the slide rail cylinder 46 drives the pneumatic gripper 41 downwards to grab the generator rotor inside the fixture 3. Then, the feeding motor 43 starts, driving the lead screw 44 to rotate. Through the lead screw transmission, the slide plate 45 moves horizontally along the translation slide rail 42 to the top of the support shaft 58. The slide rail cylinder 46 then pushes the pneumatic gripper 41 downwards, causing it to insert the grabbed generator rotor into the flexible slot. Afterwards, the slide rail... The cylinder 46 then drives the pneumatic gripper 41 to reset and move upward to avoid obstacles, so as to facilitate subsequent winding. After the winding is completed, the slide rail cylinder 46 pushes the pneumatic gripper 41 downward to extend it, so that the pneumatic gripper 41 grabs the generator rotor in the flexible slot. Then the feeding motor 43 starts and drives the lead screw 44 to rotate in the opposite direction. Through the lead screw transmission, the slide plate 45 moves in the opposite direction along the translation slide rail 42 to move above the generator rotor fixture 3, inserting the wound generator rotor into the generator rotor fixture 3, completing one round of winding processing.

[0025] Specifically, the left clamping unit includes a support 55, which is fixedly installed on the worktable 1. A clamping drive cylinder 56 is fixedly installed at the top of the support 55, and a left chuck 57 is fixedly installed at the telescopic end of the clamping drive cylinder 56. The right clamping unit includes a track 51, which is fixedly installed on the worktable 1. A sliding seat 52 is slidably installed on the track 51. A connecting shaft 53 is fixedly installed at the end of the sliding seat 52, and a right chuck 54 is fixedly installed at one end of the connecting shaft 53. A translation drive component that is connected to the sliding seat 52 is installed inside the worktable 1.

[0026] The translation drive uses a linear motor, translation screw, or translation cylinder. When the generator rotor is inserted into the flexible slot at the top of the support shaft 58, the translation drive drives the sliding seat 52 to move closer to the generator rotor along the track 51, so that the sliding seat 52 drives the right chuck 54 to move closer to the generator rotor through the connecting shaft 53. At the same time, the clamping drive cylinder 56 drives the left chuck 57 to move closer to the generator rotor, so that the right chuck 54 cooperates with the left chuck 57 to clamp and position the generator rotor.

[0027] Specifically, the rotary drive assembly includes a wound motor 61, an eccentric block 69, and a transmission unit. The eccentric block 69 is rotatably mounted on the connecting shaft 53, and the winding frame 610 is fixedly mounted on one end of the eccentric block 69. The wound motor 61 is fixedly mounted on the sliding seat 52, and the wound motor 61 is connected to the eccentric block 69 through the transmission unit, so that the wound motor 61 can drive the eccentric block 69 to rotate around the connecting shaft 53 as the fulcrum through the transmission unit. The transmission unit includes a drive wheel 62, a transmission shaft 65, and a driven wheel 68. The drive wheel 62 is fixedly mounted on the output shaft of the wound motor 61, and the transmission shaft 65 is rotatably mounted on the sliding seat 52. The two ends of the transmission shaft 65 are respectively fixedly mounted with a transmission wheel 63 and a drive wheel 66. The drive wheel 62 and the transmission wheel 63 are connected by a transmission belt 64. The driven wheel 68 is fixedly mounted on one side of the eccentric block 69, and the drive wheel 66 and the driven wheel 68 are connected by a drive belt 67.

[0028] During winding, the winding motor 61 drives the drive shaft 65 to rotate through the transmission cooperation between the drive wheel 62, the transmission wheel 63, and the transmission belt 64. The drive shaft 65 then drives the eccentric block 69 to rotate around the connecting shaft 53 through the transmission cooperation between the drive wheel 66, the driven wheel 68, and the drive belt 67. This causes the eccentric block 69 to drive the winding frame 610 to make circular motion, thus winding the generator rotor. The center of gravity of the eccentric block 69 is located on the side away from the winding frame 610, which can balance the winding frame 610 and improve the stability of the eccentric block 69 and the winding frame 610 during rotation, thereby improving the winding stability.

[0029] Specifically, the wire cutting assembly includes a bracket 611, which is fixedly mounted on the workbench 1. A limiting frame 613, capable of guiding and limiting the copper wire, is fixedly mounted on the bracket 611. A wire cutting unit, capable of cutting the copper wire passing through the limiting frame 613, is also mounted on the bracket 611. The wire cutting unit includes a shearing cylinder 612, which is fixedly mounted on the top of the bracket 611. A connecting rod 615 is slidably inserted into the telescopic end of the shearing cylinder 612. A pressure block 614 is fixedly mounted on the bottom end of the connecting rod 615. A spring 616 is fitted around the outer ring of the connecting rod 615, abutting against the pressure block 614 and the telescopic end of the shearing cylinder 612. A blade 617 located on one side of the pressure block 614 is also fixedly mounted on the telescopic end of the shearing cylinder 612. During winding, the copper wire passes through the limiting frame 613, thus allowing the limiting frame 613 to guide and limit the copper wire. When winding is complete, the shearing cylinder 612... Simultaneously, the pressure block 614 and the blade 617 are driven to move towards the limiting frame 613. Since the pressure block 614 initially extends to the front end of the blade 617, it can first move onto the limiting frame 613 to press and position the copper wire. Then, the shearing cylinder 612 continuously drives the blade 617 to move downward, causing the blade 617 to cut the copper wire. The pressure block 614 and the telescopic end of the shearing cylinder 612 slide relative to each other, so that the pressure block 614 maintains the pressing state on the copper wire under the elastic force of the spring 616. By setting the telescopically sliding pressure block 614, it can not only press and limit the copper wire when the blade 617 cuts the copper wire, so that the blade 617 can cut the copper wire stably, but also press and position the cut copper wire end, preventing the copper wire end from shaking and displacing, so that the copper wire end can be wound onto the generator rotor during the next round of generator rotor winding processing.
