Description

Technical Field

[0001] This utility model belongs to the field of motor technology, specifically relating to the production of rotors for motors, and more particularly to a winding device for generator production. Background Technology

[0002] In the field of motor manufacturing, winding is one of the key processes that determines motor performance. For generator rotors or DC motor stators that use external winding technology, the windings are usually first wound on a special winding mold and then transferred to a plastic coil support that serves as a skeleton. To achieve this automated process, the winding equipment is usually equipped with a support turntable that can move back and forth and rotate at indexes to clamp the coil support.

[0003] Currently, the common method for fixing coil supports on this support turntable is a mechanical clamping scheme. Specifically, a bolt tightening mechanism is set on the turntable, and the bolts are manually tightened so that their ends directly press against the side of the coil support, using friction to fix it to the working surface of the turntable. Since the coil support needs to be manually loaded and unloaded for each winding cycle, and tightening the bolts is a time-consuming operation, the tightening and loosening of the bolts in frequent production cycles accumulates a lot of auxiliary time, becoming a bottleneck to improving the overall production cycle and resulting in low overall production efficiency of the equipment.

[0004] Therefore, how to solve the problem of frequent bracket disassembly and assembly occupying a long winding cycle is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0006] This disclosure provides at least one winding device for generator production to solve the technical problem of frequent bracket disassembly and assembly occupying a long winding cycle.

[0007] In a first aspect, embodiments of this disclosure provide a winding device for generator production, comprising: a frame on which a lead wire assembly, a winding assembly, a cutting assembly, and a support platform are disposed; the winding assembly and the support platform are disposed opposite to each other; the support platform includes a slide, on which a turntable is disposed, and locking structures are disposed on both sides of the turntable; and a winding bracket adapted to be fitted onto the locking structure on either side.

[0008] In one optional embodiment, the locking structure includes a stop plate disposed on the turntable, a central post disposed on one side of the stop plate, and the winding bracket is adapted to be sleeved on the central post.

[0009] In one optional embodiment, a blind hole is provided on one end face of the stop plate away from the central column, a slot is provided on the end face of the blind hole, and a limiting hole communicating with the blind hole is provided on the side of the stop plate.

[0010] In one alternative embodiment, a long rod is provided inside the blind hole, one end of which is provided with a plug that matches the slot, and the other end is provided with a lifting tube extending to the outside of the blind hole.

[0011] In one alternative embodiment, a spring is fitted at one end of the long rod, with one end of the spring connected to the end face of the stop plate and the other end connected to the lifting cylinder.

[0012] In one alternative embodiment, the end of the insert is provided with a chamfered surface.

[0013] In one alternative embodiment, the winding bracket includes a support plate adapted to be fitted onto the central post and abut against the stop plate; one side of the support plate is provided with equally spaced branching rods, and adjacent branching rods form their own winding gaps.

[0014] In one alternative embodiment, a suspension plate is provided on the circumferential surface of the support plate.

[0015] In one optional embodiment, the suspension plate is provided with a rod that matches the limiting hole; the rod is provided with a locking hole that matches the insert block.

[0016] In one alternative implementation, the insert, locking hole, and slot are polygons with consistent outlines.

[0017] The beneficial effect of this utility model is that it provides a winding device for generator production; By setting up a locking structure, the winding bracket is no longer fixed by repeatedly turning traditional bolts. During installation, only the lifting cylinder needs to be operated to instantly complete the rigid locking; disassembly is done by reversing the operation. This process requires no tools, and the operation is simple and fast, significantly reducing equipment waiting time and realizing the rapid, tool-free clamping and disassembly of the winding bracket, which greatly improves production efficiency. The precise radial positioning is achieved through the precise cooperation between the support plate of the winding bracket and the central column of the locking structure. The winding bracket provides an extremely stable installation base, ensuring that there is no movement under high-speed rotation and winding tension, thus fundamentally guaranteeing the accuracy of the number of winding turns, neat wiring, and consistent shape. It achieves extremely high positioning accuracy and connection rigidity, ensuring the stable and reliable winding quality. The locking action is completed automatically by the spring. The operator only needs to perform a simple "push-press-release" or "press-remove" action, without having to judge the bolt tightening torque. This eliminates the problem of excessive looseness (slippage) or excessive tightness (damage to threads or brackets) caused by improper torque, reduces the difficulty of operation and labor intensity, and improves the safety and consistency of operation.

[0028] Research has revealed the following drawbacks of existing technologies: Currently, the common method for fixing coil supports on the turntable is a mechanical clamping scheme. Specifically, a bolt tightening mechanism is installed on the turntable, and the bolts are manually tightened so that their ends directly press against the side of the coil support, using friction to fix it to the turntable working surface. Since the coil support needs to be manually loaded and unloaded for each winding cycle, and tightening the bolts is a time-consuming operation, the tightening and loosening of the bolts accumulates a significant amount of auxiliary time during frequent production cycles, becoming a bottleneck for improving the overall production cycle and resulting in low overall equipment production efficiency.

[0029] Therefore, how to solve the problem of frequent bracket disassembly and assembly occupying a long winding cycle is a technical problem that urgently needs to be solved in this field.

[0030] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0033] like Figures 1 to 4As shown, some embodiments provide a winding device for generator production, including: a frame 1; the frame 1 is the rigid support foundation and structural platform of the entire winding device, and its core function is to support and accurately fix all functional modules such as lead wire assembly 2, winding assembly 3, cutting assembly 4 and support platform 5, ensuring that they maintain a stable and reliable relative positional relationship during high-speed, repetitive winding operations. The high rigidity of the frame 1 can effectively absorb and isolate vibration, preventing the reduction of the alignment accuracy of each component due to its own deformation or vibration, thereby ensuring the quality and consistency of the final winding. Its design as the skeleton of the equipment is the fundamental prerequisite for the high-precision and long-term stable operation of automated equipment. The frame 1 is equipped with a lead wire assembly 2, a winding assembly 3, a cutting assembly 4, and a support platform 5.

[0034] Lead wire assembly 2: The lead wire assembly 2 is mounted on the frame 1 and located at the beginning of the winding process. Its core function is to guide, transport, and control the pretension of the enameled wire used for winding in an orderly manner. It usually includes a guide wheel, tensioner, straightening mechanism, etc. This assembly can ensure that the enameled wire released from the spool is transported smoothly and straight to the winding area with a constant and appropriate tension, eliminating wire twisting, looseness, or excessive tightness. By providing a stable and controllable wire supply, the lead wire assembly 2 reduces problems such as uneven winding, misaligned wire arrangement, or wire damage caused by wire fluctuations from the source. It is a prerequisite for obtaining high-quality, high-density windings.

[0035] The winding assembly 3 is the core actuator of the equipment. It is fixed on the frame 1 and is positioned opposite the support platform 5. It mainly consists of a winding spindle and a wire laying device. It is used to drive the wire nozzle to rotate at high speed according to a preset trajectory, so as to accurately wind the wire into the gap formed by the splitting rod 62 of the winding support 6. Its relative positional relationship with the support platform 5 is crucial to ensure the spatial coordination between the winding action and the winding support 6. Its motion accuracy, speed and stability directly determine the accuracy of the number of turns, the tightness of the arrangement and the regularity of the shape of the winding. In this embodiment, due to the optimization of the fixing method of the winding support 6, a stable "target" is provided for the winding assembly 3 to achieve high-speed and continuous winding, thereby giving full play to its high efficiency.

[0036] The cutting component 4 is usually integrated near the winding component 3 or set independently in a suitable position on the frame 1. When a winding cycle (such as when a coil is wound) ends, the cutting component 4 performs a precise wire cutting action. Its action needs to be precisely linked with signals such as the stopping of the winding component 3 and the movement or rotation of the support platform 5 to ensure that the wire is cut in the correct position, so as to prepare for the wire end of the next winding cycle. The fast and neat cutting action is one of the key links to achieve efficient continuous production and reduce manual intervention.

[0037] The support platform 5 is the core functional platform that supports and drives the winding bracket 6. It serves as a bridge connecting the winding action and the winding workpiece. Its design directly affects the production cycle and automation level of the equipment. Specifically, mounting positions for the winding bracket 6 are provided on both sides of the support platform 5. The winding assembly 3 is arranged opposite to the support platform 5; the support platform 5 includes a slide 51, a turntable 52 is provided on the slide 51, and locking structures 53 are provided on both sides of the turntable 52; the winding bracket 6 is suitable for being fitted onto the locking structure 53 on either side.

[0038] The locking structure 53 includes a stop plate 531 set on the turntable 52, and a center post 539 is provided on one side of the stop plate 531. The winding bracket 6 is adapted to be fitted onto the center post 539.

[0039] The slide block 51 is the movable base of the support platform 5, which is slidably mounted on the guide rail of the frame 1. Its core function is to realize the reciprocating movement of the winding support 6 between the loading and unloading station and the winding station, and to receive the wound coil onto the support when the winding station moves. At the loading and unloading station, the operator can safely and conveniently operate the clamping and unloading of the winding support 6. At the winding station, the slide block 51 drives the winding support 6 to be precisely positioned to the optimal position to cooperate with the winding assembly 3. This separate design separates the "material handling" and "precision machining" in space, which not only ensures operational safety, but also improves the utilization rate and protection of the core winding station.

[0040] The turntable 52 is rotatably mounted on the slide 51, and its bottom is rotatably connected to the slide 51 (lower half rotates), completing the transformation of a pair of winding brackets 6 toward the winding assembly 3. In addition, the core function of the turntable 52 is to realize the indexing rotation of the winding brackets 6 (upper half rotates). During the winding process, after the winding assembly 3 completes a set of windings, the turntable 52 is precisely rotated by a set angle under the drive of the drive device (such as a servo motor). This is a programmable precision indexing capability.

[0041] In this embodiment, locking structures 53 are provided on both sides of the turntable 52, so that while winding operations are being performed on one side, the winding bracket 6 can be prepared for loading and unloading on the other side (the lower half is rotatably connected to the slide 51), creating conditions for continuous production.

[0042] The locking structure 53 is the core innovation of this utility model in solving the problem of "frequent disassembly and assembly time-consuming" mentioned in the background technology. Each locking structure 53 is set on a working surface of the turntable 52 and cooperates with the movement of the slide 51 and the rotation of the turntable 52 to form a fast and reliable clamping and releasing system for the winding bracket 6. It is mainly composed of a stop plate 531, a central column 539, and a built-in fast locking / unlocking mechanism (blind hole 532, long rod 535, insert block 536, spring 534, lifting cylinder 533, etc.). Its design principle abandons the traditional bolt tightening method and adopts a fast locking mode of "positioning + spring-driven pin". It aims to realize the "one-click" or "two-step" fast clamping of the winding bracket 6, greatly shorten the non-productive auxiliary time, and fundamentally improve the overall efficiency of the equipment.

[0043] A blind hole 532 is provided on one end face of the stop plate 531 away from the central column 539. A slot 538 is provided on the end face of the blind hole 532. A limiting hole 537 communicating with the blind hole 532 is provided on the side of the stop plate 531.

[0044] The stop plate 531 is the main load-bearing and positioning reference plate of the locking structure 53. It is fixed on the turntable 52 and provides a reliable axial positioning reference surface for the axial installation of the winding bracket 6. When the support plate 61 of the winding bracket 6 is fitted with the center column 539, its end face is tightly abutted against the stop plate 531, thereby determining the precise axial position of the winding bracket 6. This is crucial for ensuring the accuracy of the final forming position of the winding on the bracket. At the same time, the stop plate 531 also integrates blind holes 532, limiting holes 537 and other structures, which are the mounting base of the quick locking mechanism.

[0045] The center column 539 is fixedly installed on one side of the stop plate 531, coaxial or parallel to the rotation axis of the turntable 52. Its core function is to serve as the radial positioning mandrel of the winding bracket 6. The support plate 61 of the winding bracket 6 is precisely fitted onto the center column 539 through its center hole, realizing the precise alignment of the winding bracket 6 with the rotation center of the turntable 52. This cooperation of "stop plate 531 end face + center column 539" together constitutes the "one face and one axis" type of fast and accurate initial positioning of the winding bracket 6, laying the foundation for subsequent reliable locking, and also ensuring the dynamic balance and rotational accuracy of the winding bracket 6 during high-speed rotation.

[0046] A long rod 535 is provided inside the blind hole 532. One end of the long rod 535 is provided with a plug 536 that matches the slot 538, and the other end is provided with a lifting cylinder 533 that extends to the outside of the blind hole 532. The blind hole 532 is opened inside the end face of the stop plate 531 away from the central column 539. It is a cavity that accommodates the quick locking mechanism (long rod 535, spring 534, plug 536, etc.). Its axial extension direction is basically parallel to the axis of the central column 539. The design of the blind hole 532 "hides" the main moving parts of the locking mechanism inside the stop plate 531. The structure is compact and can provide protection to prevent interference from external wire ends and dust. It also makes the appearance of the equipment simpler and safer.

[0047] The slot 538 is formed on the end face of the blind hole 532 and passes through the blind hole 532. Its outline is consistent with the cross-sectional outline of the plug 536 (such as a polygon). Its main function is to serve as a "standby locking position" or "storage slot" for the plug 536. When the winding bracket 6 is not installed or has been removed, the plug 536 is pushed into and locked in the slot 538 under the thrust of the spring 534, so that the long rod 535 and the lifting tube 533 are in a stable, retracted position, avoiding the shaking of the mechanism and accidental collision damage, and also facilitating the operation during the next installation.

[0048] The limiting hole 537 is opened on the side of the stop plate 531 and communicates laterally with the blind hole 532. Its size and position correspond precisely to the insertion rod 64 on the winding bracket 6. Its core function is to receive and accommodate the insertion rod 64, thereby preventing the winding bracket 6 from rotating circumferentially. When the winding bracket 6 is fitted with the center post 539, the insertion rod 64 on its suspension plate 63 is simultaneously inserted into this limiting hole 537, preventing the winding bracket 6 from rotating relative to the stop plate 531 (i.e., the turntable 52). This ensures that the winding bracket 6 can rotate synchronously with the turntable 52 without relative sliding during the winding process, which is a necessary condition for the precise forming of the winding shape.

[0049] A spring 534 is fitted at one end of the long rod 535. One end of the spring 534 is connected to the end face of the stop plate 531, and the other end is connected to the lifting cylinder 533. The long rod 535 is the transmission and bearing rod of the quick locking mechanism. It is slidably set in the blind hole 532. It converts the external manual operation on the lifting cylinder 533 into the axial linear movement of the insert block 536. Its structural strength and guiding accuracy ensure the reliability of force transmission and the straightness of the movement of the insert block 536.

[0050] The end of the insert 536 is chamfered. The insert 536 is fixedly connected to the end of the long rod 535 facing the slot 538. It is a key part for performing the final locking action. Its cross-sectional profile is consistent with the slot 538 and the locking hole 65. Its working process is as follows: when unlocking (before installing the winding bracket 6), it is pulled out of the slot 538; when locking, it is inserted into the locking hole 65 on the insert rod 64 of the winding bracket 6 under the action of the spring 534. Through this "pin-hole" cooperation, the winding bracket 6 is reliably fixed in the axial direction after completing the initial "one side and one axis" positioning, preventing it from axially moving due to vibration or wire tension during the winding process. At the same time, it forms a double anti-rotation with the cooperation of the limiting hole 537 and the insert rod 64 in the circumferential direction, making the locking extremely stable.

[0051] The chamfered surface is set on the end edge of the insert 536 facing the slot 538. Its function is to guide the insert 536 to slide smoothly into the locking hole 65. In the final stage of locking, even if there is a slight radial or angular deviation between the locking hole 65 on the insert rod 64 and the position of the insert 536, the chamfered surface can still play a guiding role. Under the action of the spring, when the inclined surface of the insert 536 contacts the edge of the locking hole 65, a small radial component force is generated, which causes the insert 536 or the insert rod 64 to make a micro-movement, thereby automatically correcting the position and allowing the insert 536 to smoothly "slide" into the locking hole 65, realizing "automatic alignment and locking". This reduces the precision requirements of manual operation and improves the smoothness of assembly and user experience.

[0052] The lifting cylinder 533 is fixedly connected to one end of the long rod 535 that extends out of the blind hole 532. It is a manual operating component for the operator to apply force to operate the locking mechanism. Its outer diameter is usually larger than the diameter of the blind hole, making it easy for the fingers to grip or press. By pulling the lifting cylinder 533 backward (or pressing and then rotating and releasing), the spring 534 can be compressed, which will cause the insert block 536 to exit from the slot 538 or the locking hole 65, thereby unlocking. Its exposed design makes the operation intuitive and convenient, without the need for any tools.

[0053] Spring 534, typically a compression spring, is fitted onto long rod 535. One end of spring 534 abuts against or connects to the inner end face of blind hole 532 in stop plate 531, while the other end abuts against the inner end face of lifting cylinder 533. Spring 534 is the power source for the quick-locking mechanism. In its natural state, its elastic force always pushes lifting cylinder 533 outward, thereby causing long rod 535 to push insert block 536 towards slot 538. This gives the mechanism two stable states: without winding bracket 6, insert block 536 is pushed into slot 538 and self-locks; with winding bracket 6 and insert block 536 aligned with locking hole 65, its elastic force automatically pushes insert block 536 into locking hole 65 to complete the locking. The entire locking process is an automatic process driven by spring force, which is fast and reliable, and does not require manual tightening.

[0054] The winding bracket 6 is the forming skeleton and working object of the winding. It is usually made of engineering plastic. Its function is to provide support, separation and shaping for the wire during the winding process. Its structure determines the key parameters such as the shape of the final winding and the slot fill factor.

[0055] The winding bracket 6 includes a support plate 61, which is adapted to be fitted onto the central column 539 and abut against the stop plate 531; one side of the support plate 61 is provided with equally spaced splitting rods 62, and adjacent splitting rods 62 form their own winding gaps.

[0056] The support plate 61 is the main frame of the winding bracket 6. It has a central hole that mates with the central column 539. By fitting onto the central column 539 and abutting against the end face of the stop plate 531, it achieves precise positioning and installation of the winding bracket 6 on the locking structure 53. It provides an installation base for the bundle splitting rod 62 and the suspension plate 63, and transmits the force received during the winding process to the locking structure 53 and the turntable 52.

[0057] Bundle splitters 62 are multiple slender rod-shaped structures, evenly spaced on one side of the support plate 61. They are arranged in parallel and form winding gaps (or slots) between each other to accommodate the wire. During winding, the wire is guided by the winding assembly 3 and wound into these gaps in a regular manner. The shape, spacing and number of bundle splitters 62 directly determine the number of turns, layers and final shape of the coil, and are the direct carrier for winding formation.

[0058] A suspension plate 63 is provided on the circumferential surface of the support plate 61. The suspension plate 63 extends radially outward from the circumferential surface of the support plate 61. Its main function is to support and fix the insertion rod 64, and to position the insertion rod 64 in a position that is easy to align with the limiting hole 537 on the stop plate 531. At the same time, the structure of the suspension plate 63 enhances the local strength and rigidity of the support plate 61 to withstand the force on the insertion rod 64 when locking and transmitting torque.

[0059] The suspension plate 63 is provided with a plug rod 64 that matches the limiting hole 537; the plug rod 64 is provided with a locking hole 65 that matches the plug block 536; the plug block 536, the locking hole 65 and the slot 538 are polygons with the same outline.

[0060] The insertion rod 64 is fixedly mounted on the suspension plate 63. Its position and size correspond precisely to the limiting hole 537 on the stop plate 531. Its core function is to insert into the limiting hole 537 to realize the circumferential linkage between the winding bracket 6 and the turntable 52. When the insertion rod 64 is inserted into the limiting hole 537, the winding bracket 6 and the turntable 52 become one in the circumferential direction, ensuring synchronous rotation during winding. In addition, it is also the other half of the carrier for the locking action. The locking hole 65 opened on it is used to accept the insertion of the insertion block 536.

[0061] The locking hole 65 is located at the end of the insertion rod 64, and its outline is consistent with the cross-sectional outline of the insertion block 536. When the insertion rod 64 is inserted into the limiting hole 537, and the insertion block 536 is inserted into the locking hole 65 under the action of the spring 534, the final axial and circumferential composite locking of the winding bracket 6 is completed. This locking method rigidly connects the winding bracket 6 to the stop plate 531 (turntable) and can withstand the forces and vibrations of various directions and frequencies generated during the winding process.

[0062] The cross-sectional profiles of the insert 536, locking hole 65, and slot 538 are designed as consistent polygons (such as squares, hexagons, etc.). This design has a crucial anti-rotation function. When the polygonal insert 536 is inserted into the locking hole 65 or slot 538, which also has a polygonal cross-section, the contact between the polygonal surfaces completely prevents the insert 536 from rotating relative to the hole. This means that once the insert 536 is inserted into the locking hole 65, the rod 64 of the winding bracket 6 is not only axially fixed, but also achieves a gapless rigid connection with the insert 536 and then with the stop plate 531 in the circumferential direction. This completely eliminates any possible circumferential micro-movements and ensures the absolute angular stability of the winding bracket 6 under high-speed start-stop and winding stress, thereby ensuring the accuracy of the winding wiring.

[0063] Overall workflow: Preparation stage: Equipment initialization, slide 51 drives turntable 52 to move to loading and unloading position, operator holds a winding bracket 6 with completed winding (if it needs to be removed) and an empty winding bracket 6 to be wound. Quick disassembly: For the wound support 6 that has been wound, the operator presses (or pulls) the lifting cylinder 533 on the current station locking structure 53, compresses the spring 534, and drives the long rod 535 and the plug 536 to move backward, so that the polygonal plug 536 completely exits from the locking hole 65 of the plug rod 64 of the winding support 6. Then, the winding support 6 can be easily removed from the central column 539 along the axis. Release the lifting cylinder 533, and the spring 534 pushes the plug 536 forward. If it is not aligned with the locking hole, the chamfered surface at the end of the plug 536 will guide it to slide into the slot 538 for stable storage. This process usually only takes 1-2 seconds and does not require tools. Quick installation: Align the center hole of the support plate 61 of the empty winding bracket 6 to be wound with the center post 539 of the same station, and at the same time ensure that the insertion rod 64 on its suspension plate 63 is aligned with the limiting hole 537 on the stop plate 531, and push it all the way down so that the end face of the support plate 61 abuts against the stop plate 531. At this time, the insertion rod 64 has been inserted into the limiting hole 537 to achieve circumferential limiting. Then, press the lifting tube 533 to make the insertion block 536 exit from the slot 538. Rotate the lifting tube at a certain angle (e.g., 90 degrees) to make the insertion block 536 align with the locking hole 65 on the end face of the insertion rod 64. Then release the lifting tube. Under the strong thrust of the spring 534, the insertion block 536 automatically and quickly inserts into the locking hole 65 along its chamfered surface. Due to its polygonal cross section, it immediately achieves rigid locking without rotation. The installation is completed in a very short time. Switching and winding: The lead wire assembly 2 leads the wire to the winding starting point, the winding assembly 3 starts, and high-speed winding begins. After winding is completed, the wire is cut off. The turntable 52 is precisely indexed under the command of the control system. The slide 51 drives the turntable 52, which has been clamped with the winding bracket 6, to move to the winding station. The coil is pressed into the winding bracket 6 (achieving winding at a specific angle). During this process, the winding bracket 6, which is doubly locked by the polygonal insert 536 and the limiting hole 537, rotates synchronously with the turntable 52 without any relative sliding.

[0064] Continuous production: When one winding bracket 6 is winding (the lower half of the turntable 52 rotates), the operator can simultaneously load and unload another winding bracket 6 on the other side of the turntable 52 (on another locking structure 53). Once the current winding is completed, the turntable 52 can rotate 180 degrees relative to the slide 51 to move the wound workpiece to the loading and unloading station. At the same time, the other side of the workpiece that has been loaded and is to be wound is moved to the winding station, achieving near-seamless continuous production and maximizing equipment utilization.

[0065] In summary, this embodiment: By setting the locking structure 53, the fixing of the winding bracket 6 no longer relies on the repeated tightening of traditional bolts. During installation, after the support plate 61 is inserted into the central column 539 and the insertion rod 64 is inserted into the limiting hole 537, only the lifting cylinder 533 needs to be operated. Driven by the spring 534, the insertion block 536 will automatically insert into the locking hole 65 of the insertion rod 64, instantly completing the rigid locking. Disassembly is done by reversing the operation. This process requires no tools, and the operation is simple and fast. The auxiliary time for loading and unloading a single winding bracket 6 is reduced from tens of seconds in the traditional way to several seconds, significantly reducing equipment waiting time and directly improving production cycle and overall equipment efficiency. It realizes the rapid, tool-free clamping and disassembly of the winding bracket 6, greatly improving production efficiency. Radial precision positioning is achieved through the precise cooperation between the support plate 61 of the winding bracket 6 and the central column 539 of the locking structure 53; axial precision positioning is achieved through the tight fit between the end face of the support plate 61 and the end face of the stop plate 531; secondly, preliminary circumferential positioning and anti-rotation are achieved through the insertion cooperation between the insertion rod 64 and the limiting hole 537; finally, the cooperation between the polygonal contoured insertion block 536, the locking hole 65, and the slot 538 completes axial locking while completely eliminating the gap between the winding bracket 6 and the turntable 52. The multiple positioning and locking mechanism of "one side (stop plate 531), one shaft (center column 539), one pin (insertion rod 64 and limiting hole 537), and one lock (insertion block 536 and locking hole 65)" provides an extremely stable installation foundation for the winding bracket 6, ensuring that it does not move under high-speed rotation and winding tension, fundamentally guaranteeing the accuracy of the number of winding turns, neat wiring, and consistent shape; it achieves extremely high positioning accuracy and connection rigidity, ensuring the stability and reliability of winding quality; The locking action is automatically completed by the spring 534. The operator only needs to perform a simple "push-press-release" or "press-remove" action, without needing to judge the bolt tightening torque. This eliminates the problem of excessive looseness (slippage) or excessive tightness (damage to threads or brackets) caused by improper torque. The chamfered surface at the end of the insert block 536 provides automatic guidance at the moment of locking, compensating for slight deviations in the insertion position of the insert rod 64. This allows the insert block 536 to slide smoothly into the locking hole 65, reducing the demanding requirements for the operator's alignment accuracy. This makes the clamping operation easier to master, reduces mental burden and physical exertion, and improves operational safety. It reduces the difficulty of operation and labor intensity, and improves operational safety and consistency. By setting up a reciprocating slide 51 and a turntable 52 with locking structures 53 on both sides, the equipment can perform winding operations at one station (such as the left side) while the operator can simultaneously disassemble the winding bracket 6 and install new products at another station (such as the right side). When a winding cycle ends, the slide 51 retracts and the turntable 52 rotates 180 degrees, and the next winding cycle can begin immediately. The equipment idle waiting time is almost zero. This design optimizes the original serial "winding-stopping-loading-rewinding" process into a nearly parallel continuous process, maximizing the use of the equipment's core winding function time, further improving equipment utilization and capacity, realizing parallel operation of the loading and unloading station and the winding station, and optimizing the production process. The core moving parts of the locking structure 53 (long rod 535, insert block 536, spring 534) are mostly housed within the blind hole 532 of the stop plate 531. The structure is compact and protected, making it less susceptible to tangling with external wires or dust contamination, resulting in high reliability. The use of spring 534 as the drive source results in a simple structure, long lifespan, and low failure rate. Even if maintenance is required, replacing easily worn parts such as spring 534 or insert block 536 is relatively convenient, leading to low maintenance costs. Compared to traditional threaded locking mechanisms, it avoids problems such as thread wear and stripping, improving the reliability and ease of maintenance of the equipment.
