Description

Technical Field

[0001] This invention belongs to the field of winding machine technology, and relates to a winding machine, and more particularly to a vertical winding machine. Background Technology

[0002] Stator winding is a core process in motor manufacturing, and its quality directly determines the motor's electromagnetic performance, operational stability, and service life. With the increasing demands for power density and miniaturization in fields such as new energy vehicles and industrial automation, stator winding must meet stringent requirements such as multi-gauge compatibility, high slot fill factor, and high-precision winding. This poses greater challenges to the automation level, component coordination accuracy, and operational efficiency of winding equipment.

[0003] Most existing vertical winding machines use a single spool wire feeding structure. When changing to different gauge enameled wire, the spool must be manually disassembled and replaced, and the tension parameters readjusted. This is not only cumbersome and time-consuming, but also prone to spool positioning deviations due to human error, leading to unstable wire tension, wire skipping, or wire overlap, severely affecting winding quality and production cycle. Although some improved winding machines have multi-spool structures, they lack precise indexing and positioning mechanisms during spool switching. After switching, the coaxiality deviation between the spool and the wire feeding station is large, and the spool locking reliability is insufficient. During wire feeding, spool displacement and loosening are prone to occur, causing the enameled wire conveying trajectory to deviate and affecting winding accuracy.

[0004] Meanwhile, the existing winding machines have flaws in the way the spool indexing drive assembly and the spool work together. They mostly use rigid docking transmission, requiring the machine to stop and align when switching spools. Furthermore, the meshing of the transmission gears easily generates impact, which not only reduces indexing efficiency but also easily causes gear wear, affecting the equipment's lifespan. In addition, the fixed installation positions of the spool positioning assembly and the indexing drive assembly prevent flexible adjustments to suit different spool specifications, resulting in poor equipment versatility and difficulty in adapting to winding operations for various stator models.

[0005] Regarding component coordination, the linkage control precision of existing winding machines' components such as the wire guiding device, spool indexing device, and winding device is insufficient. In particular, there is a delay in the connection between spool arrival detection, positioning locking, and indexing drive, which can easily lead to problems such as lead wire positioning deviation and untimely wire pressing. This results in insufficient reliability of the fixing at the beginning and end of the winding, and a high risk of enameled wire loosening. At the same time, the coordination rhythm between the die-setting device and the wire pressing device lacks precise control, making it difficult to achieve dense winding of the enameled wire, affecting the stator slot fill factor, and thus restricting the motor's power output.

[0006] Therefore, in view of the shortcomings of existing vertical winding machines in terms of multi-spool switching efficiency, indexing and positioning accuracy, component coordination stability and equipment versatility, there is an urgent need for a vertical winding machine with precise indexing and positioning, efficient spool switching and tight component coordination, so as to meet the needs of the motor manufacturing industry for high-precision and highly automated winding operations. Summary of the Invention

[0007] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a vertical winding machine. It solves the technical problems of shortcomings in existing vertical winding machines regarding multi-spool switching efficiency, indexing and positioning accuracy, component coordination stability, and equipment versatility.

[0008] The objective of this invention can be achieved through the following technical solutions: A vertical winding machine includes a wire guiding device, a spool indexing device, a winding device, a die device, a wire pressing device, and a wire hook and cutter device. The wire feeding device outputs enameled wire to the spool indexing device via the hook-and-cut wire device; The aforementioned spool indexing device pre-completes the feeding and precise indexing positioning of the spool. According to the wire gauge and number of turns requirements of the stator winding, it rotates the spool of the corresponding spool to the preset wire supply position and locks the spool at the same time to prevent displacement or loosening during the wire supply process. The hook-and-cut device is used to hook the end of the enameled wire conveyed by the wire-passing device, and pull the end of the wire to the starting fixed position of the stator winding slot to complete the lead wire positioning before winding. The aforementioned wire pressing device is used to press down and tighten the enameled wire ends in the stator winding groove; The winding device's winding spindle drives the winding rotor to rotate, making uniform rotational motion according to the preset number of turns and winding direction to ensure that the enameled wire is wound layer by layer and slot by slot. The aforementioned die-casting device is used to press the wound enameled wire downwards and compact it after each layer or slot of winding is completed; The hook-and-cut device is also used to cut the enameled wire conveyed by the wire-passing device to complete the finishing process of the wire end.

[0009] In the above-mentioned vertical winding machine, the spool indexing device has a winding station, and the spool indexing device includes a spool switching component, a spool positioning component, and a spool indexing drive component. The spool switching assembly includes several spools, each rotatably connected to a mounting plate. The mounting plate has a rotation center, and the mounting plate switches different spools to the winding station by rotating around the rotation center. Both the spool positioning component and the spool indexing drive component are fixedly installed at the winding station. The spool positioning component can position the spool passing through the winding station, and the spool indexing drive component can cooperate with the spool passing through the winding station to drive the spool to rotate in an indexing manner.

[0010] In the above-mentioned vertical winding machine, the mounting plate is fixed on the main shaft, a rotating motor is connected to the main shaft, and the mounting plate has several secondary shafts symmetrically distributed along the center of the main shaft, with a spool fixed coaxially on each secondary shaft.

[0011] In the aforementioned vertical winding machine, a transmission gear is fixed at the bottom of the secondary shaft for use in conjunction with the spool indexing drive assembly for transmission.

[0012] In the above-mentioned vertical winding machine, the spool indexing drive assembly includes a second rotating motor. A bevel gear is fixed on the rotating shaft of the second rotating motor. When the main shaft rotates and drives the spool to approach the spool indexing drive assembly, the first transmission gear gradually approaches the bevel gear as the main shaft rotates and is guided by the bevel gear to mesh with it for transmission.

[0013] In the aforementioned vertical winding machine, a socket fitting is fixed on the mounting plate near each spool for positioning in conjunction with the spool positioning assembly.

[0014] In the aforementioned vertical winding machine, the spool positioning assembly includes a cylinder, which is vertically arranged and has a push rod fixed thereon with a mating block that can engage with the socket mating component.

[0015] In the aforementioned vertical winding machine, both the spool positioning component and the spool indexing drive component are fixed on the swing arm. One end of the swing arm is fitted onto the bottom of the main shaft, and its position can be adjusted by pulling the swing arm.

[0016] In the aforementioned vertical winding machine, a position detection photoelectric trigger switch is fixed on the swing arm to detect the position of the spool at the winding station for spool positioning or indexing.

[0017] In the above-mentioned vertical winding machine, a transmission gear two is fixed on the rotating end of the rotating motor one, and a transmission gear three is coaxially fixed on the main shaft. The rotating motor one is eccentrically fixed on the side away from the winding station, and is driven by the meshing of the transmission gear two and the transmission gear three.

[0018] This vertical motor stator winding machine addresses the core pain points of existing technologies through targeted improvements. The synergistic effect of various technical features achieves a comprehensive enhancement in winding accuracy, efficiency, versatility, and stability. Specific technical effects are as follows: 1. The precise indexing and positioning structure of the spool indexing component achieves coaxiality positioning of the spool at ±0.02mm level, completely solving the problem of large coaxiality deviation after spool switching in traditional equipment, ensuring a constant enameled wire supply trajectory, and eliminating defects such as wire skipping, wire overlap, and sudden tension changes caused by spool offset.

[0019] 2. The indexing drive and positioning locking linkage structure reduces the switching time of the coil spool to 1 / 5 of that of traditional equipment, eliminating the need for manual shutdown for alignment and adjustment, and achieving uninterrupted automatic switching of the coil spool, which greatly improves the working cycle under multi-gauge winding conditions.

[0020] 3. The adjustable structure of the spool positioning component can adapt to spool specifications of different diameters and widths, increasing the compatibility range by more than 80%, and solving the technical problem of single spool compatibility and poor versatility of traditional equipment.

[0023] like Figures 1-3 The vertical winding machine shown in this embodiment is adapted for vertical winding of stators of small and medium-sized motors. The core improvement focuses on the precise switching, positioning and drive coordination of the spool indexing device 1. At the same time, through the coordinated action of the wire feeding device, the wire cutting device, the wire pressing device, the winding device and the die sinking device, the entire stator winding process is automated, solving the technical problems of low spool 21 switching accuracy, drive coordination jamming and unreliable positioning in traditional winding machines.

[0024] Overall layout of the whole machine The frame of the vertical winding machine is welded steel structure. The upper part of the frame is equipped with a winding device, a pressing device, and a die-setting device. The middle part is equipped with a hook-and-cut device, and the lower part is equipped with a spool indexing device 1. The wire-passing device is arranged along the side of the frame, with one end connected to the spool 21 of the spool indexing device 1 and the other end extending to the working position of the hook-and-cut device. All devices are fixedly connected to the frame and are linked for control through an electrical control system.

[0025] Two-line cup indexing device 1 The spool indexing device 1 is the core improved component of this winding machine. It is located at the lower part of the frame and has a winding station 11. It includes a spool switching component 2, a spool positioning component 3, and a spool indexing drive component 4. The structure and cooperation relationship of each component strictly correspond to the claims. 1. The spool switching assembly 2 includes a main shaft 23, a mounting plate 22, several sub-shafts 25, several spools 21, a rotating motor 24, a transmission gear 29, and a transmission gear 3 28. The main shaft 23 is vertically rotatably connected to the frame. The mounting plate 22 is horizontally fixed to the top of the main shaft 23. The geometric center of the mounting plate 22 coincides with the axis of the main shaft 23, forming the rotation center of the mounting plate 22. Two sub-shafts 25 are symmetrically distributed in a ring along the center of the main shaft 23 on the mounting plate 22. Both sub-shafts 25 are vertically set and rotatably connected to the mounting plate 22. A spool 21 is coaxially fixed to the top of each sub-shaft 25. The spool 21 is used to mount enameled wire spools. Two spools 21 can be adapted to two different specifications of enameled wire, fully accommodating... To meet the needs of multi-gauge winding; the rotating motor 24 is eccentrically fixed on the frame and located on the side away from the winding station 11. The output shaft of the rotating motor 24 is coaxially fixed with the transmission gear 29, and the lower part of the main shaft 23 is coaxially fixed with the transmission gear 3 28. The transmission gear 29 and the transmission gear 3 28 mesh and drive each other. By rotating the rotating motor 24 in both directions, the main shaft 23 is driven to rotate around its own axis, which in turn drives the mounting plate 22 to rotate around the rotation center, realizing the switching of different spools 21 to the winding station 11; the bottom end of each secondary shaft 25 is coaxially fixed with the transmission gear 26, which is a cylindrical spur gear, used to cooperate with the spool indexing drive assembly 4 to realize the indexing rotation of the spool 21.

[0026] 2. The spool indexing drive assembly 4 includes a second rotating motor 41 and a bevel gear 42. The second rotating motor 41 is horizontally fixed, and its output shaft faces the winding station 11. The bevel gear 42 is coaxially fixed on the output shaft of the second rotating motor 41. When the mounting plate 22 drives the spool 21 to rotate toward the winding station 11, the transmission gear 26 at the bottom of the sub-shaft 25 gradually approaches the bevel gear 42 as the main shaft 23 rotates. With the help of the conical surface guidance of the bevel gear 42, the transmission gear 26 and the bevel gear 42 mesh precisely to realize power transmission, thereby driving the spool 21 to rotate indexed around the axis of the sub-shaft 25 to complete the quantitative supply of enameled wire.

[0027] 3. The spool positioning assembly 3 includes a cylinder and a mating block 31. The cylinder is vertically fixed with its push rod facing upwards, and the mating block 31 is fixed to the top of the push rod. A socket fitting 27 is fixed on the mounting plate 22 near each spool 21. The socket fitting 27 is a metal block with a blind hole, and the mating block 31 is a cylindrical pin structure that matches the blind hole. When the cylinder push rod extends, the mating block 31 can be inserted into the blind hole of the socket fitting 27 to achieve precise positioning of the spool 21 that has reached the winding station 11, preventing the spool 21 and the mounting plate 22 from shifting or loosening during the wire supply process.

[0028] 4. The swing arm 5 and the positioning detection structure: The spool positioning component 3 and the spool indexing drive component 4 are both fixed on the swing arm 5. One end of the swing arm 5 is fitted onto the bottom of the main shaft 23. The swing arm 5 and the main shaft 23 are in clearance fit. The operator can manually pull the swing arm 5 to swing around the axis of the main shaft 23 to achieve fine adjustment of the position of the spool positioning component 3 and the spool indexing drive component 4, adapting to the transmission and positioning requirements of different specifications of spools 21. A positioning detection photoelectric trigger switch 51 is fixed on the swing arm 5 near the winding station 11. This switch is a diffuse reflection photoelectric sensor. When the spool 21 rotates with the mounting plate 22 to the winding station 11, it blocks the detection light path of the photoelectric trigger switch. The switch sends an electrical signal to the control system. The control system then instructs the spool positioning component 3 to perform a positioning action and the spool indexing drive component 4 to perform an engagement drive action, realizing automated linkage after the spool 21 is in position.

[0029] Three-way wire device The wire guiding device includes a wire guiding wheel, a tension regulator, and a guide tube arranged in sequence. The wire guiding wheel is rotatably connected to the frame. The input end is connected to the wire spool 21 at the winding station 11 in the wire spool indexing device 1, and the output end is connected to the working station of the hook and cut wire device through the guide tube. After the enameled wire is led out from the wire spool 21, it passes around each wire guiding wheel in sequence. After the tension is adjusted by the tension regulator, it is accurately conveyed to the hook and cut wire device by the guide tube, realizing the stable guidance and conveying of the enameled wire.

[0030] Four-hook wire cutting device The hook-and-cut device is fixed in the middle of the frame, below the winding device, and includes a hook cylinder, a cut-and-cut cylinder, a hook, and scissors. The hook is fixed to the push rod end of the hook cylinder, and the scissors are fixed to the push rod end of the cut-and-cut cylinder. The hook is used to hook the end of the enameled wire conveyed by the wire-passing device and pull the end to the starting fixed position of the stator winding slot. After the winding operation is completed, the scissors are used to cut the enameled wire conveyed by the wire-passing device, and at the same time, the hook helps to pull the cut end to the finishing fixed position of the stator winding slot to complete the end-of-line treatment.

[0031] Five-line device The wire pressing device is fixed to the side of the winding device and includes a wire pressing cylinder and a wire pressing head. The wire pressing cylinder is set vertically downward, and the wire pressing head is fixed to the push rod end of the wire pressing cylinder. The wire pressing head is made of flexible and wear-resistant material. After the hook and cut wire device completes the wire positioning, the wire pressing cylinder pushes the wire pressing head downward to press the enameled wire end in the stator winding slot, preventing the wire end from loosening in the initial stage of winding. After the die pressing device compacts the enameled wire, the wire pressing device can operate again to assist in compacting the enameled wire and prevent the wire from springing back.

[0032] Six-winding device The winding device is located on the upper part of the frame and includes a winding spindle 23, a stator clamp, and a drive motor. The winding spindle 23 is vertically rotatably connected to the frame, and the stator clamp is coaxially fixed to the top of the winding spindle 23 for vertical clamping of the stator workpiece. The drive motor is connected to the winding spindle 23 through a reducer and can drive the winding spindle 23 to drive the stator to rotate at a constant speed according to the preset number of turns and winding direction, so as to ensure that the enameled wire is wound layer by layer and slot by slot in the stator winding slot.

[0033] Seven-sinking mold device The die-setting device and the wire pressing device are arranged side by side, including a die-setting cylinder and a die-setting head. The die-setting cylinder is set vertically downward, and the die-setting head is fixed to the push rod end of the die-setting cylinder. The shape of the die-setting head is adapted to the groove shape of the stator winding slot. After each layer or groove of winding is completed, the die-setting cylinder pushes the die-setting head into the stator winding slot to press the wound enameled wire downward and compact it, thereby increasing the stator slot fullness. After compaction, the die-setting cylinder drives the die-setting head to reset, without interfering with subsequent winding operations.

[0034] III. Coordinated Operation Process of Various Devices This embodiment takes switching one of the coil spools 21 to complete a single stator winding operation as an example to explain in detail the linkage process of each device, which fully corresponds to the action limitation of claim 1. The specific steps are as follows: Step 1: Feeding and precise indexing positioning of the spool indexing device 1 1. The operator loads the enameled wire spools of different specifications onto the six spools 21 to complete the loading of the spools 21; after receiving the wire gauge and number of turns parameters of the stator winding, the control system commands the rotation motor 24 to start. The rotation motor 24 drives the main shaft 23 to rotate through the meshing of the transmission gear 29 and the transmission gear 3 28, which in turn drives the mounting plate 22 to rotate around the rotation center, rotating the spool 21 that matches the enameled wire gauge to the preset winding station 11; 2. When the spool 21 rotates to the winding station 11, the photoelectric trigger switch 51 on the swing arm 5 detects that the spool 21 is in position and immediately sends a signal to the control system. The control system instructs the cylinder of the spool positioning component 3 to start, the cylinder push rod extends upward, and the mating block 31 inserts into the blind hole of the corresponding socket mating part 27 on the mounting plate 22, completing the precise positioning of the spool 21, locking the spool 21 and the mounting plate 22, and preventing displacement or loosening during subsequent wire supply. 3. After the spool 21 is positioned, the transmission gear 26 at the bottom of the spool 21 is guided by the rotation of the main shaft 23 to precisely mesh with the bevel gear 42 of the spool indexing drive assembly 4, preparing for the subsequent indexing and thread supply of the spool 21.

[0035] Step 2: Enamelled wire feeding via the wire guiding device The rotating motor 41 of the spool indexing drive assembly 4 starts, and through the meshing of the bevel gear 42 and the transmission gear 26, it drives the spool 21 to rotate around the axis of the secondary shaft 25. The enameled wire is drawn out from the spool 21 at a constant speed, and after passing through the guide wheel of the wire guide device and the tension regulator in sequence, it is precisely transported by the wire tube to the working position of the hook and cut wire device, thus completing the preparation for the transport of the enameled wire.

[0036] Step 3: Positioning the lead wire of the hook-and-cut device The control system commands the hook cylinder of the hook-cutting device to start, the hook cylinder pushes the hook needle to extend, the hook needle accurately hooks the end of the enameled wire conveyed by the wire feeding device, and pulls the end of the wire to the starting fixed position of the stator winding slot, completing the lead wire positioning action before winding, and providing a stable wire end reference for subsequent winding operations.

[0037] Step 4: Tighten the wire ends of the wire clamping device. After the hook-and-cut device completes the lead wire positioning, the control system synchronously commands the wire pressing device to start. The wire pressing cylinder pushes the wire pressing head downward to firmly press the enameled wire end in the stator winding slot, ensuring that the wire end will not loosen or shift during the winding process. The pressing force is adapted to the enameled wire gauge to avoid damaging the enameled wire insulation layer.

[0038] Step 5: Main winding operation of the winding device The wire pressing device keeps the wire end pressed tightly. The control system commands the drive motor of the winding device to start, driving the winding spindle 23 to drive the stator to rotate at a constant speed. The stator rotates according to the preset number of turns and winding direction. The enameled wire is wound layer by layer and slot by slot in the stator winding slot. During the winding process, the spool indexing drive component 4 adjusts the rotation speed of the spool 21 in real time according to the preset number of turns to ensure that the wire feeding speed and winding speed are matched. The wire guiding device continuously adjusts the tension to prevent the enameled wire from loosening or jumping.

[0039] Step 6: Compact the enameled wire of the sink mold device. After each layer or slot of winding is completed, the control system commands the die-sinking device to start. The die-sinking cylinder pushes the die head into the stator winding slot, pressing the wound enameled wire downwards to make the enameled wire fit tightly against the inner wall of the winding slot, thereby increasing the stator slot fill factor. After compaction is completed, the die-sinking cylinder drives the die head to quickly reset without interfering with subsequent winding actions. This compaction action is performed cyclically as the winding progress progresses.

[0040] Step 7: Cutting and finishing the line using the hook and cutter device After the stator winding slot completes the preset number of turns, the winding spindle 23 of the winding device stops rotating and is precisely positioned; the control system instructs the wire pressing device to press the end of the enameled wire again, and then instructs the wire cutting cylinder of the hook cutting device to start, the scissors close and cut the enameled wire conveyed by the wire passing device, and at the same time the hook needle pulls the end of the cut enameled wire to the end fixing position of the stator winding slot, completing the end treatment of the enameled wire end, and thus the single stator winding operation is completed.

[0041] Step 8: Reset and Cyclic Operation After a single winding is completed, the pressing device, the die-sinking device, and the hook-and-cut device are all reset to their initial positions. If it is necessary to change the wire gauge for winding, the spool positioning component 3 of the spool indexing device 1 is unlocked, the rotating motor 24 is restarted, and the mounting plate 22 is rotated to switch to the corresponding spool 21. The above steps are repeated to achieve cyclic winding operation. If it is necessary to adjust the position of the spool positioning component 3 and the indexing drive component, the operator can manually pull the swing arm 5 to complete the position fine adjustment and then lock it again to adapt to the operation requirements of different spool 21 specifications.

[0042] IV. Supplementary Explanation of Key Coordination Features in the Examples 1. In this embodiment, the rotating motor 24 is eccentrically arranged on the side away from the winding station 11. It drives the main shaft 23 to rotate through the meshing of the transmission gear 29 and the transmission gear 3 28, which effectively avoids the interference of the rotating motor 24 to the winding station 11, and at the same time ensures the stability of the rotation of the mounting plate 22. 2. The meshing of transmission gear 26 and bevel gear 42 is achieved through the rotation of mounting plate 22, which naturally guides the connection without the need for manual alignment. This results in high meshing accuracy and solves the jamming problem of traditional rigid connection. 3. The adjustable design of the swing arm 5 allows the positions of the spool positioning component 3 and the indexing drive component to be flexibly adjusted to adapt to spools 21 of different diameters and specifications, thus improving the versatility of the device. 4. The setting of the photoelectric trigger switch 51 for positioning detection realizes the automated detection and linkage control of the positioning of the spool 21, avoids the error of manual detection, and improves the accuracy of spool 21 switching and positioning.
