Description

Technical Field

[0001] This invention relates to the field of motor coil manufacturing technology, and more specifically to a motor coil impregnation apparatus for electric vehicle motor manufacturing. Background Technology

[0002] The insulation performance, moisture resistance, and service life of electric vehicle motors directly determine the overall stability and safety of electric vehicle operation. The varnish impregnation process of motor coils is a core process in the production and processing of electric vehicle motors. After the motor coils are impregnated, a uniform and dense insulating varnish film can be formed on the surface, which effectively improves the insulation withstand voltage, moisture resistance and corrosion resistance of the coils. At the same time, it can solidify the coil winding structure and prevent problems such as loosening and friction damage of the coils during long-term operation of the motor. It is a key processing link to ensure the quality of the motor.

[0003] Currently, most traditional impregnation devices use static impregnation, where the insulating varnish in the impregnation tank is in a static state. This results in poor fluidity and uneven distribution of the varnish, easily leading to insufficient impregnation, missed impregnation, and uneven varnish film thickness in gaps and winding dead zones of the motor coil. This significantly reduces the quality of coil insulation treatment, making the motor prone to insulation failure and localized overheating during subsequent use. Furthermore, during long-term operation, the amount of varnish in the impregnation tank gradually decreases as the varnish adheres to the surface of the motor coil after impregnation. This can lead to insufficient varnish in the impregnation tank. Transmission impregnation devices mainly use a simple method of immersing the motor coil in the impregnation tank to impregnate the coil surface. However, insufficient varnish in the impregnation tank results in insufficient impregnation of the motor coil. Adding varnish after stopping the machine reduces impregnation efficiency. Additionally, adding varnish from different batches can lead to inconsistent composition of the varnish in the impregnation tank, thus reducing the performance of the impregnated motor coil.

[0004] In view of the above, the present invention designs a motor coil impregnation device for electric vehicle motor production, which solves the above-mentioned technical problems. Summary of the Invention

One end of the pull rope is connected to the rotating wheel, and the other end of the pull rope is connected to the impregnation tank.

[0010] Preferably, the drive gear is connected to the rotating shaft via a first electromagnet, and the crank is connected to the rotating shaft via a second electromagnet. When the control component drives the immersion tank to move upward, the first electromagnet is energized and the second electromagnet is de-energized, thus fixing the drive gear and the rotating shaft together.

Through the cooperation of control components, limit frames and adjustment components, during the impregnation process, when the impregnation tank moves upward at a constant speed along the limit frame, the limit teeth drive the adjustment component to drive the paint liquid to rotate at a constant speed, avoiding paint liquid sedimentation and ensuring uniform paint liquid concentration in the early stage of impregnation; when the impregnation tank rises to the top and the coil is completely immersed in the paint, the device switches to a working state in which the coil swings uniformly left and right and the paint liquid rotates faster. The coil swing can eliminate the problems of paint liquid accumulation and dripping, and the accelerated stirring of the paint liquid can fill the tiny winding gaps of the coil, completely solving the defects of leakage and uneven paint film thickness in traditional devices, and greatly improving the insulation treatment quality of motor coils.

[0017] 2. The present invention provides a motor coil impregnation device for electric vehicle motor production.

When the impregnation tank moves to the top of the limiting frame, the stirring component accelerates its rotation. At this time, the motor coil is fully immersed in the impregnation tank. The accelerated rotation of the stirring component turns over the insulating varnish in the impregnation tank and pushes the insulating varnish towards the motor coil, thereby ensuring that the insulating varnish is immersed in every corner and dead corner of the motor coil.

Based on the described 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.

[0020] refer to Figures 1 to 8 As shown, a motor coil impregnation device for electric vehicle motor production includes a device body 1, which consists of a varnish tank support 11 and a frame 12. The varnish tank support 11 is used to place an impregnation tank 6, and the frame 12 is symmetrically arranged on both sides of the impregnation tank 6. The frame 12 is used to install control components 2. The device also includes: control components 2, symmetrically arranged on the two side frames 12, with a motor coil placement rack 3 arranged in the middle of the two side control components 2, and the two side control components 2 are respectively connected to the impregnation tank 6; the motor coil placement rack 3 is slidably arranged on the two side control components 2, and multiple motor coil placement racks are arrayed below the motor coil placement rack 3. The coil mounting hook 31 is used for coil installation; the adjustment component 5 is set in the middle of the varnish impregnation tank 6. One end of the adjustment component 5 is set in the limiting frame 4 set on the varnish tank support 11, and the other end of the adjustment component 5 is fixedly connected to the inner wall of the varnish tank; wherein, the control component 2 drives the varnish impregnation tank 6 on the varnish tank support 11 to move upward along the limiting frame 4. The limiting teeth 41 set on the limiting frame 4 drive the adjustment component 5 to drive the insulating varnish in the varnish impregnation tank 6 to rotate at a uniform speed. When the control component 2 drives the varnish impregnation tank 6 to move to the top of the limiting frame 4, the control component 2 drives the motor coil placement frame 3 to swing left and right evenly, and the adjustment component 5 drives the insulating varnish in the varnish impregnation tank 6 to rotate faster.

[0021] Specifically, the limiting frame 4 has a U-shaped structure and is slidably mounted on the paint pool support 11. Multiple limiting teeth 41 are arranged in a linear array on one side of the limiting frame 4, and the limiting teeth 41 only occupy 4 / 5 of one side of the limiting frame 4. No limiting teeth 41 are provided on 1 / 5 of one side of the limiting frame 4.

[0022] Specifically, the control component 2 includes a drive motor 21, a fixed bracket 22, a transmission component 23, a crank 24, a swing plate 25, a mounting plate 26, and a mounting shaft 27. The drive motor 21 is mounted on the frame 12 and is horizontally positioned. The output end of the drive motor 21 is fixedly connected to a rotating shaft 211, which passes through the fixed bracket 22. The fixed bracket 22 is located on one side of the drive motor 21. The mounting shaft 27 is fixedly mounted above the fixed bracket 22. The swing plate 25 is rotatably mounted on the mounting shaft 27. The mounting plate 26 is connected to one side of the swing plate 25. The mounting plate 26 has a mounting groove 261 for mounting the motor coil placement bracket 3. The transmission component 23 is located on one side of the fixed bracket 22. One end of the transmission component 23 is connected to the immersion tank 6. The crank 24 is located at the end of the rotating shaft 211, and the other end of the crank 24 is slidably mounted in a sliding groove 251 on the swing plate 25.

[0023] Specifically, the transmission component 23 includes a driving gear 231, a driven gear 232, a rotating wheel 233, and a pull rope 234. The driving gear 231 is coaxially mounted on the rotating shaft 211, and the driven gears 232 are symmetrically arranged on both sides of the driving gear 231. The driving gear 231 meshes with the driven gears 232. A rotating wheel 233 is fixedly mounted on one side of the driven gear 232. A pull rope 234 is arranged in a groove in the rotating wheel 233. One end of the pull rope 234 is connected to the rotating wheel 233, and the other end of the pull rope 234 is connected to the immersion tank 6. When the drive motor 21 rotates, it drives the driving gear 231 to move synchronously. The driving gear 231 drives the driven gear 232, causing the rotating wheel 233 to wrap around the pull rope 234, so that the immersion tank 6 moves upward along the limiting frame 4.

[0024] Specifically, the drive gear 231 is connected to the rotating shaft 211 via a first electromagnet 28, and the crank 24 is connected to the rotating shaft 211 via a second electromagnet 29. When the control component 2 drives the immersion tank 6 to move upward, the first electromagnet 28 is energized and the second electromagnet 29 is de-energized, thus fixing the drive gear 231 and the rotating shaft 211. When the control component 2 drives the motor coil placement frame 3 to swing, the first electromagnet 28 is de-energized and the second electromagnet 29 is energized, thus fixing the crank 24 and the rotating shaft 211.

[0025] Specifically, the adjustment assembly 5 includes a fixed shaft 51, a sleeve 52, a gear 53, a torsion spring 54, and rotating blades 55. The fixed shaft 51 is disposed through the immersion tank 6. The sleeve 52 is coaxially disposed on the fixed shaft 51. The gear 53 is disposed on one side of the sleeve 52, and the sleeve 52 is fixedly connected to one end of the gear 53. The sleeve 52 is connected to the fixed shaft 51 through the torsion spring 54, and the torsion spring 54 is detachably connected to the fixed shaft 51 and the sleeve 52. The rotating blades 55 are partially arranged in a circumferential array inside the immersion tank 6.

[0026] Specifically, the sleeve 52 is divided into a driving section 521 and a stirring section 522. One side of the driving section 521 is serrated 5211, and the serrated 5211 is a right triangle 5212. The stirring section 522 has a matching serrated 5211 on the side that contacts the driving section 521. The stirring section 522 is connected to the paint soaking tank 6 through a return spring.

[0027] Specifically, the inner ring of the stirring section 522 is provided with a control rod 5221, and the stirring section 522 is slidably mounted on the fixed shaft 51. The fixed shaft 51 is provided with an annular groove 511 that cooperates with the control rod 5221.

[0028] Specifically, a groove 5222 is provided on the stirring section 522, a slider 5223 is installed in the groove 5222, a rotating rod 5224 is installed in the middle of the slider 5223, and one end of the rotating rod 5224 is connected to the rotating blade 55.

[0029] Specifically, the rotating blades 55 are misaligned and installed on the circumferential surface of the stirring section 522, and the rotating blades 55 on the same axis have the same tilt direction, while the rotating blades 55 on adjacent axes have opposite tilt directions.

[0030] During operation, the operator first installs the motor coil onto the motor coil placement rack 3 using the coil mounting hook 31. Then, pre-prepared insulating varnish is added to the impregnation tank 6. The operator can slide the motor coil placement rack 3 onto the middle of the two side mounting plates 26 through the mounting groove 261 on the mounting plate 26. To ensure convenient impregnation, different motor coil placement racks 3 can be replaced later by sliding between the mounting groove 261 and the motor coil placement rack 3, thereby quickly replacing the motor coil placement rack 3 and improving the efficiency of motor coil impregnation.

[0031] Subsequently, the controller simultaneously starts the two drive motors 21, which in turn drive the rotating shaft 211 at the output end to rotate. The electromagnet 28 is energized to fix the drive gear 231 to the rotating shaft 211, causing the rotating shaft 211 to drive the drive gear 231 to move synchronously. The drive gear 231 then drives the driven gears 232 on both sides to mesh, which in turn drive the rotating wheel 233 to retract the rope. This retraction of the rope 234 causes the paint soaking tank 6 to move upwards along the limit frame 4. The movement is driven by the limiting teeth 41 on one side of the limiting frame 4, which drive the gear 53 to rotate. Since the gear 53 is fixedly connected to the drive section 521, the rotation of the gear 53 drives the drive section 521 to rotate synchronously. At this time, the sawtooth 5211 at the front end of the drive section 521 meshes with the sawtooth 5211 of the stirring section 522. The sawtooth 5211 of the drive section 521 slides along the sawtooth 5211 of the stirring section 522, pushing the stirring section 522 to move to the left and to the right through the return spring. At this time, during the rising process of the paint soaking tank 6, the stirring section 522 moves to the right through the limit teeth 41 on one side of the limiting frame 4. The mixing blades push the insulating varnish left and right to mix it, thus preventing the insulating varnish in the impregnation tank 6 from settling to the bottom. When the mixing section 522 moves left and right, it is controlled by the control rod 5221 in conjunction with the annular slide, causing the mixing section 522 to move along the path of the annular slide groove 511, thereby achieving the rotation of the mixing section 522 and ensuring that the insulating varnish is mixed evenly in the impregnation tank 6. When the impregnation tank 6 moves upward, the rotation of the mixing section 522 stores force in the torsion spring 54, and the limiting teeth 41 on the limiting frame 4 cause the mixing section 522 to rotate. The rotation speed remains constant, and the angle of the rotating blade 55 is relatively small, so that the insulating varnish in a small area is mixed and stirred. When the varnish soaking tank 6 moves to the top of the limit frame 4, the gear 53 is not engaged with the limit tooth 41, the torsion spring 54 is released, and the centrifugal force generated by the synchronous rotation of the driving section 521 and the stirring section 522 is large, so that the angle of the rotating blade 55 is large, and the insulating varnish in a large area is turbulent, thereby pushing the insulating varnish into the motor coil, so that the dead corner of the motor coil can also be immersed in the insulating varnish. When the motor coil is immersed in the immersion tank 6, electromagnet 28 is de-energized and electromagnet 29 is energized, causing the rotating shaft 211 to be fixedly connected to the crank 24. The drive motor 21 rotates, causing the crank 24 to move in a circular motion. Since one end of the crank 24 extends into the sliding groove 251 of the swing plate 25, the crank 24 causes the swing plate 25 to swing left and right. Because the mounting plate 26 is fixedly connected to the swing plate 25, the motor coil placement rack 3 causes the motor coil to swing left and right in the immersion tank 6, thus enabling the motor... The motor coil on the coil placement rack 3 can be evenly immersed in insulating varnish. After the motor coil is immersed in varnish, the first electromagnet 28 is energized and the second electromagnet 29 is de-energized. The externally set push limit frame 4 is used to make the side of the limit frame 4 without the limit tooth 41 fit with the gear 53. By reversing the drive motor 21, the pull rope 234 is unfolded, thereby placing the varnish pool 6 on the varnish pool support 11. This solves the defects of leakage and uneven varnish film thickness in traditional devices and greatly improves the insulation treatment quality of motor coils.
