Description

Technical Field

[0001] This application relates to the field of stator coil installation production equipment technology, and in particular to a stator coil installation and feeding device. Background Technology

[0002] Stator coil installation is a crucial step in motor manufacturing. It involves shaping, bundling, and welding of the coils on the stator, and its efficiency and precision directly affect the quality and cost of the motor product.

[0003] In related technologies, the following methods are commonly used to achieve stable feeding of stator coils: First, the stator coil is flipped and positioned by using a fixed bracket and manual adjustment. This method relies on manual operation, is highly flexible but inefficient. Second, a single-function robotic arm is used to grab and flip the stator coil. Although this improves the degree of automation, it has poor adaptability to the size of the stator coil and is difficult to meet the precise positioning requirements under complex working conditions. Third, a multi-axis linkage rotary platform combined with pneumatic clamps is used to achieve automatic flipping of the stator coil. Although this method has a high level of automation, it has a complex structure and high maintenance costs.

[0004] However, the above methods generally have a common problem: during the transition of the stator coil from a horizontal to a vertical state, unstable support or uncoordinated flipping action can easily cause the stator coil to shift or fall off, thereby affecting the subsequent processing accuracy and production safety. Utility Model Content

[0005] To address the technical challenge of improving the stability of stator coil loading and turning, this application provides a stator coil loading and mounting device, employing the following technical solution: A stator coil mounting and feeding device includes a feeding frame, a flipping frame rotatably mounted on the feeding frame, and a flipping drive assembly for driving the flipping frame to rotate. The flipping frame is equipped with a sliding support assembly for horizontally supporting the stator coil and a rolling support assembly for horizontally supporting a turntable. When the sliding support assembly is in a horizontal position, a stator coil with an axially horizontal orientation is placed on the sliding support assembly. When the flipping frame is rotated so that the sliding support assembly is in a vertical position, the stator coil flips to be axially vertically supported on the turntable on the rolling support assembly.

[0006] By adopting the above technical solution, the stator coil is horizontally suspended and placed on the sliding support assembly, and the turntable is vertically placed on the side of the rolling support assembly near the sliding support assembly. The flipping drive assembly drives the flipping frame to rotate. When the sliding support assembly is in a vertical position, the stator coil flips and is axially vertically supported on the turntable on the rolling support assembly. The turntable can be moved to the stator coil installation production station through the rolling support assembly, which facilitates the subsequent installation and production of the stator coil on the turntable, improves the efficiency of stator coil loading, and reduces the labor intensity of workers.

[0007] Optionally, the tilting frame includes a sliding bracket and a rolling bracket arranged perpendicular to each other, a tilting shaft fixedly connected to the sliding bracket and the rolling bracket, both ends of the tilting shaft being rotatably supported on the loading rack, one end of the tilting shaft extending out of the loading rack and being drivenly connected to the tilting drive assembly, the sliding support assembly being installed on the sliding bracket, and the rolling support assembly being installed on the rolling bracket.

[0008] By adopting the above technical solution, the sliding support and the rolling support are arranged perpendicularly to each other, and are rotatably connected to the feeding frame through the flipping shaft, making the entire flipping frame structure more stable and reliable. This design not only ensures the precise positioning of the stator by the sliding support assembly and the rolling support assembly during the flipping process, but also effectively improves the stability of the device during the flipping process and the efficiency of stator coil feeding.

[0009] Optionally, the flip drive assembly includes a flip motor mounted on the loading rack, a small sprocket fixedly mounted on the output shaft of the flip motor, and a large sprocket fixedly mounted on the extended end of the flip shaft. The large sprocket and the small sprocket are connected by a flip chain drive.

[0010] By adopting the above technical solution, the flip motor drives the small sprocket to rotate, and the small sprocket drives the large sprocket to rotate through the flip chain, so that there is a large transmission ratio between the small sprocket and the large sprocket. This transmission method can stably transmit the power of the flip motor to the flip shaft, ensuring that the flip frame rotates smoothly and accurately, thereby successfully completing the flipping operation of the stator coil from horizontal to vertical.

[0011] Optionally, the sliding support assembly includes a slide table that is slidably disposed along the length direction of the sliding bracket, a cylinder that drives the slide table to move, and two support blocks that are slidably mounted on the slide table perpendicular to the moving direction of the slide table. The two support blocks are adjusted by an adjustment assembly to make the two support blocks move synchronously towards each other or away from each other.

[0012] By adopting the above technical solution, the slide table is slidably set along the length of the sliding bracket. With the cylinder driving the slide table to move, the position of the sliding support component can be flexibly adjusted so that the end face of the stator coil abuts against the rolling support component, which improves the stability of the stator coil during the flipping process. The two support blocks are slidably installed perpendicular to the sliding table's moving direction, and can move synchronously in opposite directions or in opposite directions by adjusting the component, thereby precisely adjusting the distance between the two support blocks to ensure stable support and positioning of stator coils of different specifications, and improve the operational flexibility and reliability of stator coil assembly, processing and feeding.

[0013] Optionally, the adjustment assembly includes an adjustment screw rotatably mounted on the slide. The adjustment screw has reverse threads that are respectively threaded to the two support blocks. Rotating the adjustment screw causes the two support blocks to move toward or away from each other.

[0014] By adopting the above technical solution, the reverse threaded connection between the adjusting screw and the two support blocks enables the synchronous movement of the two support blocks in opposite directions, thereby allowing precise adjustment of the distance between the two support blocks to accommodate stator coils of different sizes. This design improves the versatility and flexibility of the device and ensures stable support of the stator coil during the flipping process.

[0015] Optionally, the inner sides of the two support blocks are provided with inclined surfaces that support the stator coils, and the included angle of the inclined surfaces is 90°.

[0016] By adopting the above technical solution, the two support blocks in the sliding support assembly have inclined surfaces on their inner sides, with an included angle of 90°. These inclined surfaces precisely conform to the outer contour of the stator coil, providing stable support during the flipping process and preventing the stator coil from shifting or tipping over. This design ensures the reliability of the stator coil when flipping from a horizontal to a vertical position, improving the operational safety and efficiency of the processing and feeding device.

[0017] Optionally, the rolling support assembly includes a plurality of feeding rollers rotatably mounted on the rolling bracket at both ends, one end of each feeding roller extending out of the rolling bracket and being connected to the rolling drive assembly, and the feeding rollers rollingly support the turntable.

[0018] By adopting the above technical solution, stable placement and efficient movement of the stator coil on the rolling support assembly are achieved. The feeding roller allows the turntable to move smoothly on the rolling support, facilitating the transportation and positioning of the stator coil. The turntable's rotating plate and support ring design not only support the stator coil but also enhance the flexibility and applicability of the device through detachable fixing. This solution works in conjunction with the flipping frame to ensure the stability of the stator coil during flipping, avoiding the risk of overturning due to center of gravity shift.

[0019] Optionally, the rolling drive assembly includes a rolling drive motor mounted on the rolling bracket, a drive sprocket fixedly mounted on the output shaft of the rolling drive motor, and a plurality of transmission sprockets fixedly mounted on the extended end of the feeding roller. The plurality of transmission sprockets are connected to the drive sprockets via a rolling chain drive.

[0020] By adopting the above technical solution, the rolling drive motor can drive multiple transmission sprockets to rotate synchronously through the drive sprocket and rolling chain, thereby realizing the coordinated work of multiple feeding rollers. This design ensures that the stator coil is vertically supported on the turntable after flipping, and the turntable can move smoothly to the next process under the drive of multiple feeding rollers, improving the efficiency of the feeding operation of the stator coil during the assembly process.

[0021] Optionally, the turntable includes a turntable supported on the feeding roller and a support ring detachably fixed to the side of the turntable away from the feeding roller for supporting the stator end face.

[0022] By adopting the above technical solution, stable support and convenient replacement of stator coils during processing are achieved. Specific effects are as follows: the combined design of the turnover plate and support ring provides stable support to the stator coil end face, ensuring the stability of the stator coil in a vertical position and preventing displacement or tipping during processing; the support ring is detachably fixed, facilitating quick replacement of stator coils of different sizes, thus improving the versatility and adaptability of the device.

[0023] Optionally, the rolling bracket is equipped with limiting baffles on both sides of the feeding roller for limiting the rotation disk, and positioning plates fixed on the rolling bracket for stopping and positioning the rotation disk.

[0024] By adopting the above technical solution, the limiting baffles are located on both sides of the feeding roller, which can limit the lateral movement range and the range of motion of the turntable during the flipping process, preventing it from shifting laterally or detaching from the feeding roller during the flipping process. The positioning plate further improves the positional accuracy of the turntable, ensuring that it is accurately placed in the designated position, thereby improving the accuracy and efficiency of stator coil feeding.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The feeding device can horizontally support the stator coil before flipping through the sliding support assembly, and make the end face of the stator abut against the turntable on one side of the rolling support assembly, ensuring the stability of the stator coil during the flipping process; after flipping, the rolling support assembly can stably support the stator coil through the turntable and drive the stator coil to move, thus smoothly entering the next process, improving processing efficiency and automation. 2. The sliding support and rolling support are arranged perpendicularly to each other and are rotatably connected to the feeding frame via a tilting shaft, making the entire tilting frame structure more stable and reliable. This design not only ensures the precise positioning of the stator coil by the sliding support assembly and the rolling support assembly during the tilting process, but also effectively improves the stability of the device during the tilting process and the efficiency of stator coil feeding. 3. The reverse threaded connection between the adjusting screw and the two support blocks enables the synchronous movement of the two support blocks in opposite directions, thus allowing for precise adjustment of the distance between the two support blocks to accommodate stator coils of different sizes. This design improves the versatility and flexibility of the device and ensures stable support of the stator coil during the flipping process; 4. The two support blocks in the sliding support assembly have inclined surfaces on their inner sides, with an included angle of 90°. This allows for precise contact with the outer contour of the stator coil, providing stable support during the flipping process and preventing the stator coil from shifting or tipping over. This design ensures the reliability of the stator coil when flipping from a horizontal to a vertical position, improving the operational safety and efficiency of the processing and feeding device. 5. The feeding rollers allow the turntable to move smoothly on the rolling support, facilitating the transport and positioning of the stator coils. The turntable's rotating plate and support ring design not only support the stator coils but also enhance the flexibility and applicability of the device through detachable fixing. This design works in conjunction with the flipping frame to ensure the stability of the stator coils during flipping, avoiding the risk of tipping over due to a shift in the center of gravity. 6. The combination design of the turnover plate and the support ring can stably support the stator end face, ensure the stability of the stator coil in the vertical position, and avoid deviation or tilting during processing; the support ring adopts a detachable fixing method, which facilitates quick replacement according to stator coils of different sizes, improving the versatility and adaptability of the device. 7. Limiting baffles are located on both sides of the feeding roller, which can limit the lateral movement range of the turntable and its range of motion during the flipping process, preventing it from shifting laterally or detaching from the feeding roller during movement or flipping. The positioning plate further improves the positional accuracy of the turntable, ensuring that it is accurately placed in the designated position, thereby improving the accuracy and efficiency of stator coil feeding.

[0032] The following combination Figures 1 to 5 This application will be described in further detail.

[0033] This application discloses a stator coil mounting and feeding device.

[0034] A stator coil mounting and feeding device. (Refer to...) Figure 1 and Figure 2The system includes a loading rack 1, a tilting rack 2, and a tilting drive assembly 3. The loading rack 1 is assembled or welded from profiles and steel plates. The tilting rack 2 is also welded from steel plates and profiles. The tilting rack 2 is rotatably mounted on the loading rack 1 via a tilting shaft 23. The tilting drive assembly 3 is connected to the tilting rack 2 via a transmission connection to drive the tilting rack 2 to tilt. A sliding support assembly 4 and a rolling support assembly 5 are installed on the tilting rack 2, arranged perpendicularly to each other. When the rolling support assembly 5 is in a horizontal position, the turntable 6 is supported by the rolling support assembly 5. When the rolling support assembly 5 is in a vertical position, the turntable 6 is also in a vertical position due to the blocking of the limiting baffle 221 on the rolling support assembly 5, and the sliding support assembly 4 is in a horizontal position. In the initial position, a stator coil 7 with its axial direction horizontal is placed on the sliding support assembly 4, with the end of the stator coil 7 abutting against the turntable 6 on one side of the rolling support assembly 5. When the rotating frame 2 is rotated so that the sliding support assembly 4 is in a vertical position, the stator coil 7 is rotated so that its axial direction is vertical on the sliding support assembly 4. Before rotation, the sliding support assembly 4 can horizontally support the stator coil 7 and make the end face of the stator coil 7 abut against the turntable 6 on one side of the rolling support assembly 5, ensuring the stability of the stator coil 7 during the rotation process. After rotation, the turntable 6 on the rolling support assembly 5 can stably support the stator coil 7 and drive the stator coil 7 to move, thus smoothly entering the next process, improving processing efficiency and automation.

[0035] Reference Figure 1 and Figure 2 The tilting frame 2 includes a sliding support 21 and a rolling support 22 arranged perpendicularly to each other. A tilting shaft 23 is provided at the connection between the sliding support 21 and the rolling support 22. The tilting shaft 23 is fixedly connected to the sliding support 21 and the rolling support 22. Both ends of the tilting shaft 23 are rotatably supported on the loading frame 1 through bearing seats. One end of the tilting shaft 23 extends out of the loading frame 1 and is connected to the tilting drive assembly 3. A sliding support assembly 4 is installed on the sliding support 21, and a rolling support assembly 5 is installed on the rolling support 22. The loading frame 1 is also provided with a first limiting member 11 and a second limiting member 12 that respectively limit the tilting of the sliding support 21 and the rolling support 22. When the support 21 is in a horizontal position, the first limiting member 11 supports the end of the sliding support 21 away from the flipping shaft 23. After flipping, when the rolling support 22 is in a horizontal position, the second limiting member 12 supports the end of the rolling support 22 away from the flipping shaft 23. With the support of the first limiting member 11 and the second limiting member 12, the position stability of the sliding support assembly 4 and the rolling support assembly 5 before and after flipping can be ensured. This design not only ensures the accurate positioning and reliable support of the stator coil 7 by the sliding support assembly 4 and the rolling support assembly 5 during the flipping process, but also effectively improves the stability of the device during the flipping process and the efficiency of feeding the stator coil 7.

[0036] Reference Figure 2The flip drive assembly 3 includes a flip motor 31, a small sprocket 32, a large sprocket 33, and a flip chain 34. The flip motor 31 is fixedly mounted on the loading rack 1, the small sprocket 32 ​​is fixedly mounted on the output shaft of the flip motor 31, and the large sprocket 33 is fixedly mounted on the end of the flip shaft 23 extending out of the loading rack 1. The large sprocket 33 and the small sprocket 32 ​​are connected by the flip chain 34. The flip motor 31 drives the small sprocket 32 ​​to rotate, and the small sprocket 32 ​​drives the large sprocket 33 to rotate through the flip chain 34. This results in a large transmission ratio between the small sprocket 32 ​​and the large sprocket 33, which can reduce the speed of the flip shaft 23. This transmission method can stably transmit the power of the flip motor 31 to the flip shaft 23, ensuring that the flip frame 2 rotates smoothly and accurately, thereby successfully completing the flipping operation of the stator coil 7 from a horizontal to a vertical state.

[0037] Reference Figure 1 The sliding support assembly 4 includes a slide table 41, a cylinder 42, two support blocks 43, and an adjustment assembly 44. The slide table 41 is slidably mounted on the sliding bracket 21 along its length via a longitudinal guide rail and a longitudinal slider. The cylinder body of the cylinder 42 is hinged to the sliding bracket 21, and the telescopic shaft of the cylinder 42 is detachably fixedly connected to the slide table 41. The two support blocks 43 are slidably mounted on the slide table 41 perpendicular to its moving direction via a transverse guide rail and a transverse slider. The two support blocks 43 are drive-connected to the adjustment assembly 44, which can adjust the two support blocks 43 to move synchronously towards or away from each other. The sliding bracket 41 is slidably set along the length of the sliding bracket 21. With the cylinder 42 driving the slide table 41 to move, the longitudinal position of the two support blocks 43 can be flexibly adjusted so that the end face of the stator coil 7 abuts against the rolling support assembly 5, which improves the stability of the stator coil 7 during the flipping process. The two support blocks 43 are slidably installed perpendicular to the moving direction of the slide table 41, and can move synchronously in opposite directions or in opposite directions by adjusting the assembly 44, thereby accurately adjusting the distance between the two support blocks 43, ensuring stable support and positioning of stator coils 7 of different specifications, and improving the operational flexibility and reliability of stator coil 7 assembly, processing and feeding.

[0038] Reference Figure 1The adjusting assembly 44 includes an adjusting screw 441, whose two ends are rotatably supported on a slide table 41 via bearing seats. The adjusting screw 441 has threads with opposite directions of rotation from its center to both ends. Two support blocks 43 also have reverse threads adapted to the adjusting screw 441. One end of the adjusting screw 441 extends out of the bearing seat, and in this embodiment, a handwheel 442 is installed at the end extending out of the bearing seat. In other embodiments, it is connected to the output shaft of the adjusting motor. Rotating the adjusting screw 441 causes the two support blocks 43 to move towards or away from each other. The reverse threaded connection between the adjusting screw 441 and the two support blocks 43 enables synchronous movement of the two support blocks 43 towards or away from each other, thereby allowing precise adjustment of the distance between the two support blocks 43 to accommodate stator coils 7 of different sizes. This design improves the versatility and flexibility of the device and ensures stable support of the stator coil 7 during the flipping process.

[0039] Reference Figure 1 The two support blocks 43 have inclined surfaces 431 supporting the stator coil 7 on their inner sides, with an included angle of 90°. The two support blocks 43 in the sliding support assembly 4 also have inclined surfaces 431 on their inner sides, with an included angle of 90°, which precisely fit the outer contour of the stator coil 7, providing stable support during the flipping process and preventing the stator coil 7 from shifting or tipping over. This design ensures the reliability of the stator coil 7 when flipping from a horizontal to a vertical position, improving the operational safety and efficiency of the processing and feeding device.

[0040] Reference Figure 1 The rolling support assembly 5 includes several feeding rollers 51. Both ends of the feeding rollers 51 are rotatably mounted on the rolling bracket 22 via bearings. The ends of the feeding rollers 51 on the same side extend out of the rolling bracket 22 and are connected to the rolling drive assembly 52. ​​The feeding rollers 51 support the rotating disk 6 for moving the stator coil 7, thus achieving stable placement and efficient movement of the stator coil 7 on the rolling support assembly 5. The feeding rollers 51 allow the rotating disk 6 to move smoothly on the rolling bracket 22, facilitating the transportation and positioning of the stator coil 7. The rotating plate 61 and support ring 62 of the rotating disk 6 not only support the stator coil 7 but also enhance the flexibility and applicability of the device through detachable fixing. This design, working in conjunction with the flipping frame 2, ensures the stability of the stator coil 7 during flipping, avoiding the risk of overturning due to a shift in the center of gravity.

[0041] Reference Figure 3The rolling drive assembly 52 includes a rolling drive motor 521, a drive sprocket 522, several transmission sprockets 523, and a rolling chain 524. The rolling drive motor 521 is mounted on the rolling support 22, and the output shaft of the rolling drive motor 521 is fixedly mounted with the drive sprocket 522. Several feeding rollers 51 have their ends extending out of the rolling support 22 and are fixedly mounted with the transmission sprockets 523. The transmission sprockets 523 and the drive sprockets 522 are connected by the rolling chain 524. A tensioning wheel 525 for tensioning the rolling chain 524 is also mounted on the rolling support 22. In this way, the rolling drive motor 521 can drive the multiple transmission sprockets 523 to rotate synchronously through the drive sprockets 522 and the rolling chain 524, thereby realizing the coordinated work of the multiple feeding rollers 51. This design ensures that the stator coil 7 is vertically supported on the turntable 6 after flipping, and the turntable 6 can move smoothly to the next process under the drive of the multiple feeding rollers 51, improving the efficiency of the feeding operation of the stator coil 7 during the assembly process.

[0042] Reference Figure 4 The turntable 6 includes a turntable plate 61 and a support ring 62. The support ring 62 is fixed to the turntable plate 61 with screws. The turntable plate 61 is supported on the feeding roller 51 with one side being flat, which realizes stable support and convenient replacement of the stator coil 7 during processing. The combined design of the turntable plate 61 and the support ring 62 can stably support the end face of the stator, ensuring the stability of the stator coil 7 in the vertical position and preventing displacement or tilting during processing. At the same time, the support ring 62 can also accommodate the coil on the stator coil 7 and effectively protect the coil. The bottom wall of the support ring 62 is detachably fixed to the turntable plate 61 with screws, which facilitates quick replacement according to different sizes of stator coil 7, improving the versatility and adaptability of the device. A handle 63 is installed on each of the two adjacent sides of the turntable plate 61 and the support ring 62 on the same side, which facilitates moving the turntable 6 during operation.

[0043] Reference Figure 2 and Figure 5The rolling support 22 is equipped with a limiting baffle 221 and a positioning plate 222. The limiting baffle 221 is installed on the rolling support 22 located on both sides of the feeding roller 51 by screws. The limiting baffle 221 is used to prevent the turntable 6 from detaching from the feeding roller 51 during flipping, and at the same time to prevent the turntable 6 from sliding laterally. The positioning plate 222 is fixedly installed on the rolling support 22 by screws, and is used to stop and position the turntable 6 in the direction of movement. The setting of the limiting baffle 221 and the positioning plate 222 effectively prevents the turntable 6 from detaching from the feeding roller 51 or moving off the feeding roller 51 during flipping or moving, ensuring the stability of the stator coil 7 assembly and processing feeding process. Among them, the limiting baffle 221 is located on both sides of the feeding roller 51, which can limit the lateral movement range and the range of motion of the turntable 6 during flipping, and prevent it from shifting laterally during movement or detaching from the feeding roller 51 during flipping. The positioning plate 222 further improves the positional accuracy of the turntable 6, ensuring that it is accurately placed in the designated position, thereby improving the accuracy and efficiency of stator coil 7 feeding. By adjusting the position of the positioning plate 222, the flipping feeding of stator coil 7 of different sizes can be met.

[0044] The implementation principle of the stator coil installation and feeding device of this application is as follows: The horizontally hoisted stator coil 7 is placed on the support block 43 of the horizontally positioned sliding support assembly 4. The cylinder 42 is connected to an external power source. The telescopic shaft of the cylinder 42 extends, pushing the slide table 41 to move towards the rolling support assembly 5, so that the end of the stator coil 7 abuts against the support ring 62 of the turntable 6. The flipping motor 31 is started, and the small sprocket 32 ​​rotates, driving the large sprocket 33 to rotate through the flipping chain 34, thereby causing the flipping frame 2 to rotate and flip. At the same time that the rolling bracket 22 abuts against the second limiting member 12, the flipping motor 31 stops working and the rolling drive is started. When the motor 521 is working, the drive sprocket 522 drives the transmission sprocket 523 to rotate through the rolling chain 524, thereby causing the feeding roller 51 to rotate and drive the turntable 6 and stator coil 7 to move to the next process, thus completing one rotation and feeding operation of stator coil 7. When it is necessary to feed stator coil 7 of different sizes, turn the handwheel 442 to adjust the distance between the two support blocks 43, and at the same time adjust the position of the positioning plate 222. When the sliding support assembly 4 is in a horizontal position, the center of the stator coil 7 on the two support blocks 43 coincides with the center of the support ring 62, ensuring that the stator coil 7 is stably supported on the support ring 62 after the rotation frame 2 is rotated.

[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
