Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and in particular discloses a winding device with an extended winding shaft. Background Technology

[0002] In the manufacturing of electrical appliances and heating elements, it is often necessary to spirally wind metal wires (such as heating wires) onto a slender, shaft-like frame. With the increasing size of products, the demand for ultra-long winding spools (reaching several meters or even longer) is growing. In existing conventional winding equipment, the winding spool is typically supported only at two points: the drive end and the tail end. When the length of the winding spool increases significantly, this two-point support method results in a lack of effective radial constraint in the middle section of the spool. During the winding process, due to the continuous tension of the wire, the extended winding spool is prone to significant deflection deformation.

[0003] This deformation can lead to uneven winding pitch, loose wire arrangement, and even wire overlap, severely affecting product quality and even causing permanent bending damage to the winding shaft. Although this problem can be alleviated by adding intermediate supports, traditional support structures are often fixed and can interfere with the axial reciprocating wire laying mechanism. This makes it impossible to achieve dynamic and interference-free effective support during continuous winding, which has become a technical bottleneck restricting the high-quality and automated production of extended coils. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems in the prior art, the purpose of this utility model is to provide a winding device with an extended winding shaft.

[0005] To achieve the above objectives, this utility model provides a winding device for an extended winding shaft, comprising a first support frame, a winding mechanism mounted on the first support frame, and a wire laying mechanism that cooperates with the winding mechanism. The winding mechanism includes a first driving member and a winding frame mounted at the output end of the first driving member. The winding frame includes a main body section and an extension section, and the main body section and the extension section of the winding frame are rotatably mounted on the first support frame along the length direction of the first support frame. The wire laying mechanism is used to drive external wire to reciprocate along the length direction of the winding frame, and the first driving member is used to drive the winding frame to rotate so that the external wire driven by the wire laying mechanism is wound in a spiral shape around the outer circumference of the winding frame.

[0006] Furthermore, the winding device also includes a support mechanism, which includes a support plate mounted on the frame, a third driving member mounted on the support plate, and a support head mounted at the output end of the third driving member. The support head has a clearance groove, the opening of which is oriented towards the radial direction of the winding frame. The third driving member is used to drive the support head closer to the winding frame so that the winding frame enters the clearance groove.

[0007] Furthermore, the clearance groove is a "U" shaped groove, an arc-shaped groove, or a "V" shaped groove, and the opening direction of the clearance groove is set towards the radial direction of the winding frame.

[0008] Furthermore, the blocking mechanism is provided in multiple sets, which are spaced apart on the first support frame along the length of the winding frame. The multiple sets of blocking mechanisms are used in conjunction with the main body section and extension section of the winding frame to limit the radial displacement of the winding frame and reduce the deformation of the winding frame during the winding process.

[0009] Furthermore, the support head is provided with a fourth driving member and an adjusting baffle that is connected to the output end of the fourth driving member. When the winding frame enters the clearance groove, the fourth driving member is used to drive the adjusting baffle to move back and forth close to the winding frame, so as to press the external wire wound on the winding frame against the outside of the winding frame.

[0010] Furthermore, the wiring mechanism includes a linear module, a transmission plate disposed at the output end of the linear module, and a guide wheel assembly disposed on the transmission plate. The linear module is used to drive the transmission plate to reciprocate along the winding frame. The guide wheel assembly includes a guide wheel bracket reciprocally disposed on the transmission plate, a plurality of first rollers and second rollers rotatably disposed on the guide wheel bracket, and the rotation axes of the first rollers and the second rollers are intersecting each other.

[0011] Furthermore, the linear module includes a mounting base on a first support frame, a second motor at one end of the mounting base, a second reducer at the output end of the second motor, and a synchronous belt assembly that is driven and connected to the second reducer. The output end of the synchronous belt assembly is provided with a sliding seat, and the transmission plate is connected to the sliding seat.

[0012] Furthermore, the mounting base is equipped with a sensor, and the winding device also includes an electronic control component that is electrically connected to the winding mechanism and the wire laying mechanism. The sensor is electrically connected to the second motor via the electronic control component. The sliding base is equipped with a sensing plate that works in conjunction with the sensor. When the sliding base moves to the sensing area of ​​the sensor, the sensor outputs a position signal to the electronic control device. The electronic control device adjusts the second drive component to stop operating or switch the movement direction of the synchronous belt assembly according to the position signal.

[0013] Furthermore, the first driving component includes a first motor mounted on a first support frame, a first reducer mounted on the output end of the first motor, and a gripper mounted on the output end of the first reducer; one end of the winding frame is fixed by the gripper, and the other end of the winding frame is rotatably mounted on the end of the first support frame away from the first motor.

[0014] Furthermore, the winding device also includes a wire feeding mechanism for providing external wire to the winding mechanism. The wire feeding mechanism includes a second support frame disposed at one end of the first support frame, a wire spool rotatably disposed on the second support frame, a mandrel disposed in the middle of the wire spool, and a second driving member connected to the wire spool for driving the wire spool to rotate. The external wire roll is used to be sleeved on the outside of the mandrel and placed on the wire spool.

[0015] Furthermore, the wire feeding mechanism also includes a third support frame disposed between the wire reel and the first support frame. The third support frame is provided with a wire passage hole, which is a strip-shaped hole. The second driving member is used to drive the wire reel to rotate so that the free end of the external wire coil carried by the wire reel passes through the wire passage hole and is guided to the wire feeding mechanism.

[0016] To address the aforementioned technical problems, this invention provides a winding device for an extended winding shaft. Its core principle lies in designing an overall structure that includes a movable stop mechanism, providing multi-point dynamic support for the extended winding shaft. The device mainly comprises a first support frame, a winding mechanism, a wire laying mechanism, and the crucial stop mechanism.

[0017] The first drive component of the winding mechanism drives the extended winding frame, which consists of a main section and an extension section, to rotate; the wire laying mechanism drives the wire to move axially along the winding frame, thus completing the spiral winding. The key innovation of this invention lies in the stop mechanism, which consists of a drive component (such as a cylinder) and a support head with a specific shaped clearance groove (such as a U-shape or V-shape), and multiple sets can be arranged along the axial direction of the winding frame.

[0018] At the start of winding, the support head, driven by the drive unit, approaches and supports the winding frame, providing solid radial support to resist deformation caused by winding tension. When the winding mechanism moves close to a certain stop mechanism, the support head can actively retract to make way for the winding mechanism. After the mechanism passes, it quickly resets to restore support, thus achieving full-range, dynamic, and stable support for the extended winding shaft without stopping the machine or interfering with the winding action.

[0019] The beneficial effects of this invention are as follows: First, it fundamentally solves the problem of bending deformation of the extended winding shaft during the winding process. Multi-point dynamic support greatly enhances the system rigidity, ensuring the uniformity of the winding pitch and the tightness of the wire arrangement, significantly improving product consistency and quality. Second, the device has a high degree of automation; the automatic avoidance function of the support mechanism ensures a continuous and uninterrupted winding process, resulting in high production efficiency.

[0020] Furthermore, in some preferred embodiments, the radial adjustment baffle added to the support head can further constrain the wire from the side, enhancing winding stability; while the integrated position sensing and electronic control system ensures precise control and safety interlocking of the wire laying stroke. This invention features an ingenious and targeted structural design, effectively overcoming the shortcomings of existing technologies and providing a reliable equipment foundation for the automated production of extended coils.

[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0031] Please see Figures 1 to 7 As shown, the present invention discloses a winding device for an extended winding shaft, comprising a first support frame 1, a winding mechanism 2 disposed on the first support frame 1, and a wire laying mechanism 3 configured to cooperate with the winding mechanism 2; the winding mechanism 2 comprises a first driving member 21 and a winding frame 22 disposed at the output end of the first driving member 21, the winding frame 22 comprising a main body section 221 and an extension section 222, the main body section 221 and the extension section 222 of the winding frame 22 being rotatably disposed on the first support frame 1 along the length direction of the first support frame 1; the wire laying mechanism 3 is used to drive external wire to reciprocate along the length direction of the winding frame 22, and the first driving member 21 is used to drive the winding frame 22 to rotate so as to cooperate with the external wire driven by the wire laying mechanism 3 to spirally wind it around the outer circumference of the winding frame 22.

[0032] Specifically, the first support frame 1 adopts a robust welded steel frame structure, with mounting holes at the bottom for fixing to the working ground using anchor bolts. The first drive component 21 of the winding mechanism 2 is a high-torque servo motor (750W), which is fixedly mounted at the end of the first support frame 1 via a motor mount. The winding frame 22 adopts a split design, including a main body section 221 and an extension section 222, which are connected by a precision flange connection structure.

[0033] One end of the main body section 221, near the first drive member 21, is directly connected to the output shaft of the first drive member 21 via a high-strength coupling, while the other end is machined with a positioning stop and bolt connection holes. The corresponding end of the extension section 222 has a matching mating structure, which is coaxially fixed to the main body section 221 via positioning pins and high-strength bolts. The winding frame 22 is supported by: support seats with sealed bearings are installed at multiple key locations on the main body section 221 and the extension section 222. These support seats are mounted on the crossbeam of the first support frame 1 via adjusting shims, forming a multi-point support structure to ensure the stability of the long shaft system during high-speed rotation.

[0034] The cable laying mechanism 3 is located on one side of the winding frame 22 and includes a second drive component 64, a transmission assembly, and a guide assembly. The second drive component 64 is a servo motor, which is mounted on the side of the first support frame 1 via a motor bracket. The transmission assembly uses a precision ball screw pair or a synchronous belt drive mechanism to convert the rotational motion of the second drive component 64 into linear motion. The guide assembly uses a high-rigidity linear guide rail, and a cable laying guide nozzle mounting seat 311 is installed on the slider. The external cable is guided through the cable laying guide nozzle, which can be replaced with a corresponding specification based on the cable diameter.

[0035] While the first driving member 21 drives the winding frame 22 to rotate at a constant speed, the second driving member 64 drives the wire guide nozzle to move back and forth at a constant speed along the axis of the winding frame 22 through the transmission component. The coordinated movement of the two causes the wire to be tightly wound on the outer surface of the winding frame 22 in a set spiral trajectory.

[0036] Specifically, the winding device further includes a retaining mechanism 4, which includes a support plate 41 on the first support frame 1, a third driving member 42 on the support plate 41, and a support head 43 at the output end of the third driving member 42. The support head 43 has a clearance groove 431, the opening of which is directed toward the radial direction of the winding frame 22. The third driving member 42 is used to drive the support head 43 closer to the winding frame 22 so that the winding frame 22 enters the clearance groove 431.

[0037] In this embodiment, the support plate 41 is a rectangular steel plate, which is vertically fixed to the side beam of the first support frame 1 by welding or high-strength bolts. Mounting holes are opened in the upper middle part of the support plate 41, and the third drive component 42 is a cylinder, which is securely mounted on the support plate 41 by bolts. The support head 43 is made of high-strength engineering plastic or nylon material, and a specially shaped clearance groove 431 is machined on the side facing the winding frame 22. The cross-section of this groove is U-shaped or V-shaped, and the opening direction of the groove is precisely set towards the radial direction of the winding frame 22 to ensure that the outer circumferential surface of the winding frame 22 can be well accommodated.

[0038] The support head 43 is fixedly connected to the piston rod or push rod end of the third drive member 42 via a connector, so that the third drive member 42 can drive the support head 43 to make precise linear movements along the radial direction of the winding frame 22.

[0039] In this embodiment, four sets of blocking mechanisms 4 are provided. The four sets of blocking mechanisms 4 are evenly spaced on the first support frame 1 along the length direction of the winding frame 22. Two sets correspond to the support positions of the main body section 221 of the winding frame 22, and the other two sets correspond to the support positions of the extension section 222.

[0040] The installation position of each set of support mechanisms 4 is precisely calculated to ensure a reasonable multi-point support system along the entire length of the winding frame 22. During the winding process, the third drive members 42 of all support mechanisms 4 operate simultaneously, driving their respective support heads 43 to move towards the central axis of the winding frame 22 until the winding frame 22 reliably enters the clearance grooves 431 of each support head 43. By adjusting the output force of the third drive member 42, the support head 43 can apply an appropriate radial constraint force to the winding frame 22, providing effective support while avoiding excessive friction.

[0041] By setting multiple actively controllable support mechanisms 4 along the entire length of the winding frame 22, a complete radial support system is formed, which significantly enhances the rigidity of the extended winding frame 22 during high-speed rotation and effectively suppresses bending deformation caused by its own weight and winding tension. The innovative clearance groove 431 design enables the support head 43 to form a surface contact support with the winding frame 22, which greatly improves the support stability and load-bearing capacity.

[0042] The coordinated operation of the four sets of support mechanisms 4 ensures that the winding frame 22 receives uniform and reliable support throughout its entire length, fundamentally solving the vibration and deformation problems during the winding process of ultra-long winding shafts; the modular design of the support mechanism 4 allows the equipment to flexibly adapt to winding requirements of different lengths, greatly improving the equipment's versatility and practicality.

[0043] Specifically, in this embodiment, a fourth driving component 44 is detachably mounted on the upper part of the support head 43 body via bolts. The fourth driving component 44 is a compact cylinder, fixedly mounted via a bracket. The adjusting baffle 45 is made of a smooth metal plate, and its working surface is machined into an arc shape that matches the outer contour of the winding frame 22. The adjusting baffle 45 is connected to the support head 43 body via a slide rail mechanism, and can make precise reciprocating movements in a direction perpendicular to the axis of the winding frame 22 under the drive of the fourth driving component 44.

[0044] Once the winding frame 22 enters the clearance groove 431 of the support head 43, the fourth drive unit 44 immediately activates, driving the adjusting baffle 45 to move towards the winding frame 22 until its arc-shaped working surface contacts the surface of the wire on the winding frame 22 and applies appropriate clamping force. The clamping force of the adjusting baffle 45 can be precisely controlled by the output parameters of the fourth drive unit 44, ensuring that the wire is effectively clamped without causing deformation or damage. During the winding process, the adjusting baffle 45 always maintains radial constraint on the wound wire, keeping the wire tightly attached to the surface of the winding frame 22.

[0045] By adding an actively adjustable clamping mechanism, real-time radial constraint on the wound wire is achieved, effectively solving the technical problems of wire slack and loose arrangement in traditional winding equipment; the dynamic clamping effect of the adjusting baffle 45 ensures that each layer of wire can be tightly attached to the surface of the winding frame 22, significantly improving the structural compactness and overall quality of the winding product.

[0046] This design is particularly suitable for applications requiring high winding density. Precise clamping force control ensures both effective winding and prevents mechanical damage to the wire. The entire clamping process is perfectly coordinated with the winding process, achieving simultaneous winding and clamping, significantly improving production efficiency and product consistency.

[0047] Specifically, the linear module 31 is fixedly mounted on the side of the first support frame 1 via a mounting base, and its direction of movement is parallel to the axis of the winding frame 22. The linear module 31 is a precision ball screw type or synchronous belt type module, including core components such as guide rails, sliders, and drive motors. The transmission plate 32 is a rectangular metal plate, which is fixed to the slider of the linear module 31 via a connector, and moves in a precise linear reciprocating motion along the guide rail with the slider.

[0048] The guide wheel bracket 331 is mounted on the transmission plate 32 via a linear slide rail pair, allowing for fine-tuning movement perpendicular to the axis of the winding frame 22. A locking device is provided on the guide wheel bracket 331 to fix its position relative to the transmission plate 32. Multiple first rollers 332 are mounted side-by-side on the lower part of the guide wheel bracket 331 via bearing seats, with the axes of each first roller 332 parallel to each other and forming a specific angle with the axis of the winding frame 22. A group of second rollers 333 is mounted on the upper part of the guide wheel bracket 331 via an independent mounting bracket, with their roller axes intersecting the axes of the first rollers 332, preferably perpendicularly.

[0049] The wire passes sequentially through the guide channel formed by the first set of rollers 332 and the second set of rollers 333. The first set of rollers 332 is responsible for constraining the displacement of the wire in one direction, while the second set of rollers 333 constrains its displacement in the vertical direction, thereby achieving spatial orientation and straightening of the wire. By adjusting the position of the guide roller bracket 331, the guiding requirements of wires with different diameters can be accommodated.

[0050] By adopting a double roller group structure with cross-axis arrangement, the wire is effectively constrained and straightened in two vertical directions, which significantly improves the straightness of the wire before entering the winding point; the adjustable design of the guide roller bracket 331 enables the equipment to quickly adapt to wires of different specifications, greatly enhancing the versatility and adaptability of the equipment.

[0051] The application of the linear module 31 ensures the high precision and stability of the wire laying mechanism 3's movement, providing a reliable guarantee for obtaining a uniform winding pitch. The overall structure is compact and reasonable, and maintenance is simple, effectively solving the technical problems of insufficient guiding accuracy and difficult adjustment that exist in traditional wire laying mechanisms 3.

[0052] Specifically, the mounting base 311 is a long strip steel structure, fixedly mounted on the upper part of the first support frame 1 by bolts, and its mounting reference surface is precision machined to ensure straightness. The second motor 312 is a 750W servo motor, fixed to one end of the mounting base 311 by a motor mounting flange. The second reducer 313 is a planetary gear reducer, whose input end is connected to the output shaft of the second motor 312 via a coupling, and whose output end is fixed to the drive pulley of the synchronous belt assembly via a keyway.

[0053] The synchronous belt assembly includes a driving pulley, a driven pulley, a synchronous belt, and a tensioning device. The driving pulley is connected to the output end of the second reducer 313, and the driven pulley is mounted on the other end of the mounting base 311 via a bearing seat. The synchronous belt is a high-strength rubber synchronous belt with a toothed structure on its inner side that meshes with the pulley. The sliding seat 315 is an aluminum alloy casting or a machined steel part, with a clamping device at its bottom for fixing the synchronous belt and a slider on its side that mates with the linear guide rail on the mounting base 311. The transmission plate 32 is connected to the mounting surface of the sliding seat 315 by bolts and moves precisely linearly along the linear guide rail together with the sliding seat 315.

[0054] Three sensors 316 are installed at both ends and key positions in the middle of the mounting base 311. These sensors 316 are proximity switches and are mounted in the T-slots of the mounting base 311 via adjustable brackets. A metal sensing plate 317 is correspondingly installed on the sliding base 315. When the sliding base 315 moves into the detection area of ​​the sensor 316, the sensor 316 immediately outputs a signal to the electronic control component 5. The electronic control component 5 is a programmable controller. After receiving the position signal from the sensor 316, it sends control commands to the second motor 312 according to a preset program to achieve precise positioning, automatic stopping, or direction switching of the sliding base 315.

[0055] Through the coordinated operation of sensor 316 and electronic control component 5, precise detection and automatic control of the moving position of the winding mechanism 3 are achieved, effectively ensuring the accuracy and reliability of the winding process. The modular linear module 31 design not only provides smooth and reliable linear motion, but also facilitates installation, debugging and maintenance. Intelligent position control enables the equipment to automatically identify the end point of the stroke and accurately change direction, avoiding the impact and wear of mechanical limit devices, and greatly improving the service life and operational stability of the equipment. The programmable control mode allows the equipment to flexibly adapt to different winding length requirements, significantly improving the applicability and production efficiency of the equipment.

[0056] Specifically, the first motor 211 is a high-torque servo motor, which is fixedly mounted on the end of the first support frame 1 via a motor mount. The first reducer 212 is a planetary gear reducer or a cycloidal pinwheel reducer, and its input end is directly connected to the output shaft of the first motor 211 via a high-strength coupling to ensure the accuracy and reliability of power transmission. The output end of the reducer is equipped with a specially designed gripper 213, which adopts a three-jaw or four-jaw self-centering structure and is driven to open and close synchronously by hydraulic or pneumatic means.

[0057] The winding frame 22 has a connecting structure near the drive end that matches the gripper 213, typically a shaft head with a central positioning hole and a drive plane. When the winding frame 22 is installed, its shaft head precisely inserts into the central positioning hole of the gripper 213. Under the drive action, the gripper 213 retracts radially, firmly clamping the winding frame 22 and providing sufficient transmission torque. The other end of the winding frame 22 is supported by a heavy-duty rolling bearing in a bearing housing at the distal end of the first support frame 1. The bearing housing contains a self-aligning roller bearing, which can withstand radial loads and compensate for certain installation errors.

[0058] The entire drive system forms a stable power transmission path of motor-reducer-gripper 213-winding frame 22-remote support. After the first motor 211 increases its output torque through the reducer, it reliably transmits the rotational motion to the winding frame 22 via the gripper 213, while the bearing support at the far end ensures the stability and coaxiality of the winding frame 22 during high-speed rotation.

[0059] By adopting the clamp 213 type connection structure, the winding frame 22 can be quickly clamped and reliably fixed, which significantly improves the production efficiency and operation convenience of the equipment. The application of the reducer not only ensures sufficient output torque, but also reduces the requirements for motor power, thereby improving the economy and reliability of the system. The design of the two-end support effectively improves the stress state of the long winding frame 22, greatly reduces vibration and deflection deformation during rotation, and ensures the stability and consistency of winding quality. The modular drive system design facilitates maintenance and component replacement, reducing equipment maintenance costs and downtime.

[0060] Specifically, the winding device further includes a wire feeding mechanism 6 for providing external wire to the winding mechanism 2. The wire feeding mechanism 6 includes a second support frame 61 disposed at one end of the first support frame 1, a wire spool 62 rotatably disposed on the second support frame 61, a spindle 63 disposed in the middle of the wire spool 62, and a second driving member 64 that is pulverically connected to the wire spool 62 for driving the wire spool 62 to rotate. The external wire roll is used to be sleeved on the outside of the spindle 63 and placed on the wire spool 62.

[0061] In this embodiment, the second support frame 61 is a steel structure frame, fixed to the ground with anchor bolts, maintaining an appropriate distance from the first support frame 1 to ensure sufficient space for wire laying. The wire reel 62 is a large steel structure turntable, mounted on the upright plate of the second support frame 61 by heavy-duty rolling bearings, enabling smooth rotation. A mandrel 63 is located at the center of the wire reel 62. This mandrel 63 is a detachable structure, connected to the center of the wire reel 62 via a flange, and its outer diameter is designed to be a standard size to accommodate different specifications of wire coils.

[0062] The second drive unit 64 is a servo motor or torque motor with an encoder, connected to the main shaft of the wire reel 62 via a reduction gear. This drive system can precisely control the rotation speed and angle of the wire reel 62, ensuring a smooth and controllable wire feeding process. A guide device and tension detection mechanism are installed at the wire outlet of the wire reel 62 to monitor changes in wire tension in real time and provide feedback to the control system.

[0063] When installing the outer wire coil, it is directly sleeved on the outside of the mandrel 63 and stabilized by the support surface of the coil 62. The free end of the wire is guided to the winding mechanism 2 via the guide wheel. Throughout the unwinding process, the second drive unit 64 automatically adjusts the rotation speed of the coil 62 according to the winding speed to maintain constant wire tension.

[0064] Preferably, a third support frame 65 is added between the second support frame 61 and the first support frame 1. This support frame adopts a welded steel structure and is fixed to the ground by anchor bolts. A strip-shaped cable hole 66 is opened on the top crossbeam of the third support frame 65. The length direction of the strip-shaped hole is perpendicular to the ground, and its length dimension is significantly larger than its width dimension, forming a vertical hole structure.

[0065] The inner side of the strip-shaped wire guide hole 66 is inlaid with a wear-resistant engineering plastic bushing. The inner surface of the bushing is smoothly transitioned to reduce frictional resistance when the wire passes through. This bushing is removable and replaceable to accommodate wires of different diameters. The position of the wire guide hole 66 is precisely calculated to ensure that the wire led out from the wire reel 62 can pass through at the optimal angle and be guided to the wire laying mechanism 3.

[0066] After the free end of the outer wire coil on the reel 62 is drawn out from the coil, it first passes through the strip-shaped wire guide hole 66 on the third support frame 65, and then finally reaches the wire laying mechanism 3 via other guiding devices. The second drive unit 64 adjusts the rotation speed of the reel 62 in real time according to the winding speed to ensure that the wire laying process is coordinated and synchronized with the winding process. The design of the strip-shaped hole gives the wire greater freedom when passing through, and it can adaptively adjust its passing position to avoid additional wear caused by positional deviation.

[0067] By setting a third support frame 65 with a strip-shaped wire guide hole 66, a stable and reliable transition guide is provided for the wire, effectively reducing vibration and swaying during the wire feeding process. The special design of the strip-shaped hole allows the wire to automatically adjust its passing position according to tension changes, avoiding wire squeezing and excessive wear that may be caused by traditional round holes. The entire wire feeding path has been optimized to ensure a smooth transition of the wire from the wire feeding reel 62 to the wire laying mechanism 3, significantly improving winding quality and production efficiency. The modular structure of the third support frame 65 is easy to install and adjust, and can adapt to different equipment layout requirements, enhancing the applicability and flexibility of the equipment.

[0068] The following describes the workflow of this utility model patent in conjunction with the specific embodiments described above: After the equipment is started, the operator first installs the external wire coil onto the spool 62 of the wire feeding mechanism 6, and then passes the free end of the wire through the strip-shaped wire hole 66 of the third support frame 65 and the guide wheel assembly 33 of the wire laying mechanism 3 in sequence, and fixes it to the starting end of the winding frame 22. After setting the winding parameters through the electronic control component 5, the first motor 211 of the first drive component 21 drives the winding frame 22 to rotate at a constant speed through the reducer and the gripper 213. At the same time, the linear module 31 of the wire laying mechanism 3 drives the guide wheel assembly 33 to move at a constant speed along the axis of the winding frame 22 under the precise positioning control of the sensor 316, so that the wire is wound around the outer periphery of the winding frame 22 in a set spiral trajectory.

[0069] During the winding process, the third drive member 42 of the four sets of support mechanisms 4 drives the support head 43 to approach the winding frame 22, causing it to enter the clearance groove 431 to provide radial support. The adjusting baffle 45, under the action of the fourth drive member 44, applies appropriate clamping force to the wound wire. When the wire laying mechanism 3 moves near the support mechanism 4, the sensing system controls the support mechanism 4 to temporarily retract to avoid it, and immediately resets after passing. Throughout the winding process, the second drive member 64 of the wire laying mechanism 6 maintains a wire laying speed that matches the winding speed, ensuring stable wire tension. The equipment automatically stops operating once the set number of winding turns is reached.

[0070] By using a split-type winding frame 22 and a multi-point support system, the technical problems of insufficient rigidity and easy deformation in traditional equipment when processing long winding shafts are effectively solved, and high-precision processing of ultra-long winding shafts is achieved. The innovative intelligent wire arrangement system ensures the uniformity of the winding pitch and the tightness of the wire arrangement through precise positioning by sensor 316 and cross roller guide mechanism.

[0071] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
