Description

Technical Field

[0001] This invention belongs to the field of motor technology, and specifically discloses a stator winding structure that can be quickly connected and installed. Background Technology

[0002] In the manufacturing of high-efficiency, high-power-density motors, flat wire winding stators have become the mainstream direction of industry development due to their advantages such as high slot fill factor, good heat dissipation performance, and compact structure. However, compared with traditional round wire motors, the manufacturing process of flat wire stators, especially the installation of pre-formed flat wire coils into the slots of the stator core, faces significant technological challenges and has become a bottleneck restricting the improvement of its production efficiency and product quality.

[0003] Currently, the mainstream process is to first bundle and weld multiple flat wires together to form a complete coil unit, and then install the coil unit as a whole onto the stator teeth of the stator core.

[0004] The installation process relies entirely on the operator's hand-eye coordination and experience. The operator needs to make fine adjustments to the coil simultaneously in multiple circumferential and radial dimensions to align it with the slots of each stator tooth. Due to the large number of stator teeth (usually 24, 48, or even more), and the fact that the line of sight is easily obstructed by the coil and the iron core itself, the alignment process is extremely tedious, time-consuming, and requires a high level of skill from the operator, resulting in high personnel training costs.

[0005] Therefore, we propose a stator winding structure that can be quickly installed to overcome the drawbacks of existing technologies, such as reliance on manual labor, low efficiency, and high quality risks. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the background art, and to propose a stator winding structure that can be quickly connected and installed, including a base, a rotating assembly, a positioning disk, a rotating disk, a stator core, a centering clamping assembly, a lifting assembly, a recording assembly, and a mounting disk. The positioning disk is mounted on top of the base via a mounting assembly. The rotating assembly is located at the bottom of the positioning disk, and the output shaft of the rotating assembly is connected to the bottom axis of the rotating disk. The rotating disk is located above the positioning disk. Two sets of centering clamping assemblies are provided and symmetrically installed on both sides inside the positioning disk. The stator core... The core is fixed to the top of the rotating disk by two sets of centering clamping assemblies. An embedded ring is fixedly installed in the middle of the stator core. Stator teeth are evenly arranged in the circumferential direction inside the embedded ring. Locking grooves are opened in the embedded ring and between adjacent stator teeth. The lifting assembly is set on one side of the top of the positioning disk. The telescopic end of the lifting assembly is connected to the top of the mounting disk through a connecting assembly. The camera assembly is set at the bottom of the mounting disk. A shaft is fixedly installed at the center of the bottom of the mounting disk. Guide positioning elements are evenly arranged in the circumferential direction inside the shaft.

[0007] In the above technical solution, the mounting component further includes a bottom ring fixedly embedded in the upper surface of the base, and stabilizing rods are installed at equal intervals along the circumferential direction on the upper surface of the bottom ring, with one end of each of the stabilizing rods penetrating and inserting into the upper part of the positioning disk.

[0008] In the above technical solution, the rotating component further includes a motor fixedly installed at the bottom of the positioning disk, and a rotating shaft is fixedly installed on the output shaft of the motor, with the upper end of the rotating shaft connected to the bottom of the rotating disk.

[0009] In the above technical solution, the centering clamping assembly further includes a sliding shell fixedly installed on one side inside the positioning disk. A screw is rotatably inserted inside the sliding shell, and a slider is threaded onto the outside of the screw. The slider is slidably connected inside the sliding shell. A support rod is fixedly installed on the upper surface of the slider, and a clamping block is fixedly installed at the upper end of the support rod. Rubber blocks are fixedly installed at both ends of the clamping block, and the inner walls of both sets of rubber blocks abut against the outer wall of the stator core.

[0010] In the above technical solution, the lifting assembly further includes a cylinder fixedly installed on one side of the top of the positioning plate, a positioning plate fixedly installed on the telescopic end of the cylinder, a slide rod vertically installed on the top wall of the positioning plate and on the side near the cylinder, and one end of the positioning plate slidably sleeved on the outside of the slide rod.

[0011] In the above technical solution, the connecting component further includes a connecting post fixedly installed at the bottom of the positioning plate, and the mounting plate is fixedly sleeved on the outside of the connecting post.

[0012] In the above technical solution, the camera component further includes a plurality of visual scanning locators, which are installed at equal intervals along the circumferential direction at the bottom of the mounting plate.

[0013] In the above technical solution, the guide positioning component further includes an input pipe installed inside the shaft, a connecting box installed at the end of the input pipe away from the shaft, one side of the connecting box being fixedly installed on the outer wall of the shaft, a guide rod being fixedly connected in the middle of the outer wall of the connecting box away from the shaft, air nozzles being symmetrically installed inside the connecting box, multiple sets of ball bearings being embedded inside the end of the guide rod away from the connecting box, an air inlet connecting pipe being installed above the inside of the shaft, a stop ring being slidably installed outside the guide rod, and limit blocks being fixedly installed on both sides of the outer wall of the stop ring.

[0014] In the above technical solution, flat coils are fitted on the outside of each stator tooth, and insulating sleeves are wrapped on both sides of each flat coil. Locking plates are movably fitted inside the locking groove, and the two sides of the locking plates are movably attached to the outer edges of two adjacent flat coils.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Through the coordinated action of the rotating disk, centering clamping assembly, and lifting assembly, combined with the visual scanning locator at the bottom of the mounting plate, the system can automatically and accurately identify the spatial position of each stator tooth. Subsequently, the motor of the rotating assembly drives the rotating shaft and rotating disk to rotate, which can drive the stator core to rotate slowly around the axis. With the help of the camera assembly above, the stator teeth are scanned around the entire circumference. After the stator core and guide rod are positioned, the guide rod and the pneumatically driven abutment ring cooperate to accurately push the flat coil pre-fitted on the guide rod onto the target stator tooth. This process completely replaces the traditional alignment method that relies on human eyesight and manual operation, greatly improving alignment accuracy and installation consistency, and significantly reducing the reliance on the operator's skills.

[0017] 2. A locking and flexible pushing mechanism is formed by the ball bearings embedded at the front end of the guide rod and the sliding abutment ring. The pre-bundled flat coil is first sleeved on the guide rod. The insulating sleeve protects the outer insulation layer of the flat coil. Compressed air is connected to the air inlet pipe and delivered to the air nozzle through the input pipe and connecting box. The abutment ring is driven to slide along the guide rod, and the abutment ring drives the coil to be smoothly pushed into the stator tooth groove, thereby completing the quick sleeve connection between the flat coil and the stator tooth.

[0018] 3. After the coil is inserted into the slot, the locking plate is inserted into the locking groove between the adjacent stator teeth. The two sides of the locking plate can fit against the outer edge of the adjacent flat coil to limit the coil displacement radially and prevent the coil from vibrating during motor operation.

[0028] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0030] like Figures 1-8 The stator winding structure shown includes a base 1, a rotating assembly, a positioning disk 4, a rotating disk 5, a stator core 10, a centering clamping assembly, a lifting assembly, a recording assembly, and a mounting plate 14. The positioning disk 4 is mounted on top of the base 1 via a mounting assembly. The rotating assembly is located at the bottom of the positioning disk 4, and its output shaft is connected to the bottom axis of the rotating disk 5. The rotating disk 5 is located above the positioning disk 4. Two sets of centering clamping assemblies are symmetrically installed on both sides inside the positioning disk 4. The stator core 10 is fixed by the two sets of centering clamping assemblies. At the top of the rotating disk 5, an inner ring 30 is fixedly installed in the middle of the stator core 10. Stator teeth 27 are evenly arranged in the inner ring 30 along the circumferential direction. Locking grooves 31 are opened in the inner ring 30 and between adjacent stator teeth 27. The lifting component is set on one side of the top of the positioning disk 4. The telescopic end of the lifting component is connected to the top of the mounting disk 14 through the set connecting component. The camera component is set at the bottom of the mounting disk 14. A shaft 22 is fixedly installed at the bottom axis of the mounting disk 14. Guide positioning parts are evenly arranged in the inner ring 22 along the circumferential direction.

[0031] In this embodiment, the stator core 10 is placed on the rotating disk 5 and fixed by the centering clamping components on both sides to ensure its accurate and stable position during subsequent rotation and installation. The lifting component drives the mounting disk 14 to descend, bringing the camera component at its bottom close to the stator core 10. The rotating component drives the rotating disk 5 to rotate the stator core 10. The camera component performs a panoramic scan and position identification of the circumferentially distributed stator teeth 27. After the system identifies and positions the teeth, the shaft 22 at the bottom of the mounting disk 14 and the guide positioning component on it are aligned with the target stator teeth 27. The flat coil 26 pre-installed on the guide positioning component is precisely fitted into the stator teeth 27 under guidance and pushing. After the flat coil 26 is installed, the locking piece 25 is locked into the locking groove 31, pressing the adjacent flat coil 26 radially to prevent it from loosening.

[0032] The mounting components include a bottom ring 3 fixedly embedded on the upper surface of the base 1, and stabilizing rods 2 are installed at equal intervals along the circumferential direction on the upper surface of the bottom ring 3. One end of each of the stabilizing rods 2 is inserted through and into the upper part of the positioning plate 4.

[0033] In this embodiment, the bottom ring 3 is fixed on the base 1 as a basic mounting plane, and multiple stabilizing rods 2 are evenly distributed along the circumference to form an environmentally friendly column structure. As a result, the positioning plate 4 can maintain horizontality and stability when subjected to the forces of rotating, lifting and other components.

[0034] The rotating assembly includes a motor 19 fixedly mounted on the bottom of the positioning disk 4, and a rotating shaft 18 fixedly mounted on the output shaft of the motor 19. The upper end of the rotating shaft 18 is connected to the bottom of the rotating disk 5.

[0035] In this embodiment, the output shaft of the motor 19 drives the rotating disk 5 to rotate through the connection of the rotating shaft 18, which can drive the stator core 10 to rotate to any specified angle. After the camera component scans, the corresponding position of the stator teeth 27 and the upper guide positioning component is adjusted.

[0036] The centering clamping assembly includes a sliding shell 6 fixedly installed inside one side of the positioning disk 4. A screw 7 is rotatably inserted inside the sliding shell 6. A slider 9 is threaded onto the outside of the screw 7. The slider 9 is slidably connected inside the sliding shell 6. A support rod 8 is fixedly installed on the upper surface of the slider 9. A clamping block 17 is fixedly installed on the upper end of the support rod 8. Rubber blocks 20 are fixedly installed on both ends of the clamping block 17. The inner walls of the two sets of rubber blocks 20 abut against the outer wall of the stator core 10.

[0037] In this embodiment, the operator rotates the screw 7. Since the slider 9 and the sliding housing 6 form a sliding pair and are threadedly connected to the screw 7, the rotational motion is converted into the linear motion of the slider 9. The slider 9 drives the clamping block 17 to move towards the outer surface of the stator core 10 via the support rod 8. When the rubber blocks 20 at both ends of the clamping block 17 contact the outer wall of the stator core 10, they can provide sufficient friction to achieve fastening, and their elastic material can also play a buffering and protective role, preventing scratches on the outer surface of the stator core 10.

[0038] The lifting assembly includes a cylinder 11 fixedly installed on one side of the top of the positioning plate 4. A positioning plate 13 is fixedly installed on the telescopic end of the cylinder 11. A slide rod 12 is vertically installed on the top wall of the positioning plate 4 and on the side close to the cylinder 11. One end of the positioning plate 13 is slidably sleeved on the outside of the slide rod 12.

[0039] In this embodiment, the extension and retraction of the cylinder 11 directly drives the positioning plate 13 to move up and down. The sliding sleeve of the slide rod 12 and one end of the positioning plate 13 forms a sliding guide pair, ensuring that the positioning plate 13 can only move smoothly in the vertical direction, thereby ensuring the alignment accuracy of the guide positioning component on the mounting plate 14 below and the stator teeth 27. After the stator teeth 27 complete the winding, they can be lifted upwards to remove the docked stator core 10.

[0040] The connecting assembly includes a connecting post 15 fixedly installed at the bottom of the positioning plate 13, and a mounting plate 14 fixedly sleeved on the outside of the connecting post 15;

[0041] In this embodiment, the connecting column 15 serves as a rigid connecting rod, with its upper end fixed to the positioning plate 13 and its lower end fixedly sleeved by the mounting plate 14. When the positioning plate 13 is driven to rise and fall by the cylinder 11, the mounting plate 14 can be moved through the connecting column 15.

[0042] The camera assembly includes several visual scanning locators 21, which are installed at equal intervals along the circumferential direction at the bottom of the mounting plate 14.

[0043] In this embodiment, several visual scanning positioners 21 can be industrial cameras. When the visual scanning positioner 21 is working, it will take pictures and scan above the stator core 10 and transmit the images to an external computer. The computer processor will accurately calculate the angle and position of each stator tooth 27 through image recognition to ensure accurate alignment during subsequent docking.

[0044] It should be noted that the combination of this scanning system and an industrial computer is a common existing technology, so it will not be elaborated on further.

[0045] The guide positioning component includes an input pipe 23 connected to the inside of the shaft 22. The end of the input pipe 23 away from the shaft 22 is connected to a connecting box 28. One side of the connecting box 28 is fixedly installed on the outer wall of the shaft 22. A guide rod 24 is fixedly connected to the middle of the outer wall of the connecting box 28 away from the shaft 22. Air nozzles 29 are symmetrically connected and installed inside the connecting box 28. Multiple sets of ball bearings 32 are embedded in the end of the guide rod 24 away from the connecting box 28. An air inlet connecting pipe 16 is connected and installed above the inside of the shaft 22. A retaining ring 34 is slidably installed on the outside of the guide rod 24. Limiting blocks 33 are fixedly installed on both sides of the outer wall of the retaining ring 34. Flat coils 26 are fitted on the outside of the stator teeth 27. Insulating sleeves 35 are wrapped on both sides of the flat coils 26. Locking plates 25 are movably locked inside the locking groove 31. The locking plates 25 are movably attached to the outer edges of two adjacent flat coils 26 on both sides.

[0046] In this embodiment, the flat coil 26 is pre-fitted onto the guide rod 24, and can be operated directly above the stator core 10 during operation. Therefore, the operating space has a high degree of freedom and is easy to fit. The ball bearing 32 is set at one end of the guide rod 24. On the one hand, it can prevent excessive sliding when guiding the flat coil 26 to move downward, and on the other hand, it can reduce the friction between the flat coil 26 and the guide rod 24 when blowing air at the end.

[0047] Under the scanning of the pre-recording component, the stator teeth 27 of the stator core 10 are aligned with the corresponding guide rods 24 as driven by the rotating component, allowing for docking. Compressed air is delivered from an external compression device to the air inlet connecting pipe 16, then through the input pipe 23 to the connecting box 28, and finally ejected from the air nozzle 29. The airflow acts on the abutment ring 34, pushing it to slide outward along the guide rod 24. The abutment ring 34 contacts and pushes the flat coil 26, allowing it to slide smoothly along the guide rod 24 until it is fully engaged with the stator teeth 27. The limiting block 33 limits the end of the abutment ring 34's stroke to prevent it from coming out. After blowing air, negative pressure (inhalation) is applied to guide the abutment ring 34 back to the root of the air nozzle 29.

[0048] Working principle: First, the stator core 10 is placed on top of the rotating disk 5 and fixed by two sets of symmetrically arranged centering and clamping assemblies. Specifically, rotating the screw 7 drives the slider 9 to slide inside the sliding shell 6, which in turn moves the support rod 8 and the clamping block 17, so that the rubber block 20 is tightly pressed against the outer wall of the stator core 10, achieving precise centering and clamping of the stator core 10 and ensuring its stability during installation.

[0049] Subsequently, the lifting assembly is activated, and cylinder 11 pushes positioning plate 13 down along slide bar 12. This, via connecting column 15, moves mounting plate 14 and shaft 22 downwards, bringing the visual scanning locator 21 at the bottom of mounting plate 14 close to stator core 10. The visual scanning locator 21 automatically identifies and scans the position of stator teeth 27. Simultaneously, the rotating assembly is activated, and motor 19 drives rotating shaft 18 and rotating disk 5 to rotate slowly, causing stator core 10 to rotate around its axis, achieving full-circumference scanning and positioning of stator teeth 27. This replaces traditional manual alignment, improving accuracy and efficiency.

[0050] After scanning and positioning are completed, the guide positioning component is aligned with the target stator tooth 27. The pre-formed flat coil 26 is pre-fitted onto the guide rod 24, and the flat coil 26 is wrapped with an insulating sleeve 35 to protect the insulation layer. An external vacuum compressed air device is connected through the air inlet connection pipe 16. The airflow enters the connecting box 28 through the input pipe 23 and is ejected from the air nozzle 29, driving the abutment ring 34 to slide outward along the guide rod 24. Under the limitation of the limiting block 33, the abutment ring 34 smoothly pushes the flat coil 26, and the ball bearing 32 at the front end of the guide rod 24 reduces friction, accurately pushing the flat coil 26 into the slot of the stator tooth 27 to complete the rapid fitting.

[0051] Finally, after all the flat coils 26 are installed in place, the locking plate 25 is inserted into the locking groove 31 between the adjacent stator teeth 27. The two sides of the locking plate 25 are attached to the outer edge of the adjacent flat coils 26 to radially restrict the displacement of the flat coils 26, prevent vibration during the operation of the assembled motor, and ensure that the winding structure is firm and reliable.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
