Abstract
Description
Technical Field
[0001] This invention relates to the field of winding machine technology, and more particularly to a fine wire winding machine for winding extremely fine wires and simultaneously bonding them with adhesive tape. Background Technology
[0002] In the production of products such as miniature precision coils and microfilament composite tapes, it is necessary to wind wires thinner than a human hair into specific shapes and apply interlayer adhesive tape during the winding process. However, due to the extremely small diameter and low tensile strength of the wires used, the winding, adhesive application, and cutting processes in existing equipment are usually completed step-by-step by multiple independent devices. This results in a fragmented equipment structure, disjointed operation, low production efficiency, and the risk of accidental pulling or damage to the extremely fine wires when multiple devices work together. Furthermore, the low level of automation affects the efficiency of continuous operation. Summary of the Invention
[0003] Therefore, it is necessary to provide a fine wire winding machine to solve at least one of the technical problems in the background art.
[0004] A filament winding machine includes a winding mechanism, an adhesive applicator, an adhesive applicator moving module, and a lead-in mechanism. The winding mechanism includes a winding body formed by multiple winding plates, and the winding body is connected to a first rotary drive component that drives it to rotate around its own axis. The adhesive applicator includes a hollow support and multiple sets of adhesive applicators disposed thereon. The hollow support is arranged around the periphery of the winding body, and the adhesive applicators are used to press adhesive tape onto the wire wound on the winding plates and cut the tape-adhered wire into a flat strip. The adhesive applicator moving module is connected to and drives the adhesive applicator to reciprocate along the axial direction of the winding body. The lead-in mechanism is located on one side of the winding mechanism and is used to guide external filaments onto the winding plates.
[0005] Furthermore, each adhesive application assembly includes an adhesive dispensing roll, an adhesive take-up roll, a first pressure roller, and a second pressure roller; the first and second pressure rollers are spaced apart along the conveyor belt direction and can be raised and lowered independently; the adhesive dispensing roll and the adhesive take-up roll are each connected to a rotary drive unit, which is used to actively release the adhesive belt and cooperate in recovering the adhesive belt with attached wires, respectively.
[0006] Furthermore, each adhesive application assembly also includes a roller cutting assembly, which includes a cutter and a cutting drive for driving the cutter to rise and fall. The cutter is located between the first pressure roller and the second pressure roller and is used to cut the wire pressed onto the surface of the winding board.
[0007] Furthermore, the winding plate consists of four rectangular plates that enclose a cuboid winding body; there are four sets of adhesive application components, each corresponding to one of the four winding plate positions; the adhesive application mechanism simultaneously completes the application of adhesive, cutting, and winding of the wire on the surface of the four winding plates during one axial reciprocating stroke.
[0008] Furthermore, the winding mechanism also includes a wire end fixing assembly, which is located in the gap between two adjacent winding plates. The assembly includes a fixing seat, a fixing block, and an elastic reset member. The fixing seat has a guide groove, and the fixing block is embedded in the guide groove and can slide up and down along the guide groove. The elastic reset member is located in the guide groove, with its upper end abutting against the fixing block and its lower end supported on the support structure below the fixing seat. It is used to apply an upward elastic preload to the fixing block. The top of the fixing block has multiple protrusions for winding and fixing fine wires. The multiple protrusions are arranged at intervals along the axial direction of the winding body. Under the action of external force, the fixing block can overcome the elastic preload and sink down along the guide groove, causing the wire end wound on the protrusion to automatically fall off.
[0009] Furthermore, the lead wire mechanism includes a three-axis moving module and an anti-jump wire assembly and a guide pin assembly mounted on the three-axis moving module; the anti-jump wire assembly includes multiple anti-jump wire devices spaced apart, and the guide pin assembly is located below the anti-jump wire assembly, including multiple hollow guide pins spaced apart; the anti-jump wire devices and hollow guide pins correspond one-to-one in the vertical direction to form a continuous wire passage.
[0010] Furthermore, the lead wire mechanism also includes a cutting clamp assembly, which is located on one side of the guide pin assembly and includes multiple spaced pneumatic cutting components. Each pneumatic cutting component corresponds to the position of each hollow guide pin, and the pneumatic cutting component has both wire cutting and clamping functions.
[0011] Furthermore, the three-axis moving module includes a first transverse component, a lifting component, a second transverse component, and a third transverse component; the lifting component is disposed on the first transverse component, and the second and third transverse components are both disposed on the lifting component and are parallel to each other; the anti-jumping wire component and the guide pin component are connected to the second transverse component, and the shearing clamp component is connected to the third transverse component.
[0012] Furthermore, the filament winding machine of this application also includes a feeding mechanism, which includes multiple feeding stations. Each feeding station is equipped with an active unwinding assembly, a dynamic buffer assembly, and a tensioner. The active unwinding assembly includes an unwinding drive for driving the raw filament roll to rotate and unwind. The dynamic buffer assembly includes a guide rail and a first guide wheel slidably mounted thereon. The first guide wheel is used to buffer the tension fluctuation of the wire by sliding when the unwinding speed and the winding speed are mismatched. The tensioner is located between the dynamic buffer assembly and the lead-in mechanism and is used to adjust the tension of the filament before it enters the lead-in mechanism.
[0013] Furthermore, the hollow support is also equipped with a fan assembly to provide airflow to the adhesive application area.
[0014] The beneficial effects of this invention are as follows: By integrating the winding mechanism, adhesive application mechanism, adhesive application moving module, and lead wire mechanism into one unit, the adhesive application mechanism reciprocates along the winding body axis. After winding is completed, adhesive application and cutting can be performed directly on the surface of the winding body. Each process is completed continuously at the same station, with tight action connection. This reduces the need for multiple transfers and pulling of extremely fine wires, lowers the risk of wire breakage, and improves production efficiency. Attached Figure Description

[0026] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.
[0027] In the description of this invention, it should be noted that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0029] The present invention will be further described in detail below with reference to some specific embodiments.
[0030] This invention provides a fine wire winding machine for winding extremely fine wires and simultaneously bonding them with adhesive tape to form a composite strip material with alternating layers of wire and adhesive tape. This composite strip material can be used as a winding raw material for micro coils that require interlayer bonding, such as micro precision hollow cup motor coils and voice coil motor coils.
[0031] like Figure 1 As shown, the filament winding machine of this embodiment mainly includes a winding mechanism 10, an adhesive applicator 20, an adhesive applicator moving module 30, a lead wire mechanism 40, a feeding mechanism 50, and a control module 60. The feeding mechanism 50 is located on the side of the lead wire mechanism 40 away from the winding mechanism 10, and is used to provide the lead wire mechanism 40 with filaments of stable tension. The lead wire mechanism 40 is located on one side of the winding mechanism 10, and is used to guide the filaments fed by the feeding mechanism 50 onto the winding mechanism 10. The winding mechanism 10 is used to wind the introduced filaments onto the surface of its winding body 11. The adhesive applicator 20 is arranged on the outer periphery of the winding mechanism 10 and is driven by the adhesive applicator moving module 30 to reciprocate along the axial direction of the winding body 11, used to press the adhesive tape onto the wound wire layer and cut the wire adhered to the adhesive tape to form a flat strip. The control module 60 is electrically connected to the drive components of each mechanism, and is used to coordinate and control the automatic operation of winding, adhesive applicator, cutting, and winding actions. The operation display screen is located on the opposite side of the winding body 11, serving as the human-machine interface for the control module 60, used by operators to set parameters and monitor the equipment's operating status. The following is a detailed description of each component.
[0032] like Figure 1 and Figure 10As shown, the feeding mechanism 50 includes multiple feeding stations, each including an active unwinding assembly 51, a dynamic buffer assembly 52, and a tensioner 53. The active unwinding assembly 51 includes an unwinding drive 511 for actively rotating and unwinding the raw material filament roll. The unwinding drive 511 is a rotary motor, which coordinates with the linear speed of the subsequent winding mechanism to prevent the extremely fine filament from breaking due to passive pulling. The dynamic buffer assembly 52 is used for tension buffering when the unwinding speed and the winding consumption speed are mismatched. It includes a guide rail 521 and a first guide wheel 522 slidably mounted on it. The first guide wheel 522 is connected to the guide rail 521 via a sliding base and can slide freely along the guide rail 521. When the winding speed is temporarily less than the unwinding speed, the first guide wheel 522 slides backward on the guide rail 521, temporarily storing the excess wire in the rail's travel to prevent the wire from becoming loose. When the winding speed is temporarily greater than the unwinding speed, the first guide wheel 522 slides forward, releasing the previously stored excess wire to prevent excessive tension from causing wire breakage. Limiting structures can be installed at both ends of the guide rail 521; when the travel is exhausted, an alarm is triggered or the unwinding speed is adjusted, thus achieving sensorless mechanical dynamic tension balance.
[0033] Furthermore, each feeding station also includes a second guide wheel 523 and a third guide wheel 524 for guiding the wire's direction. Specifically, the second guide wheel 523 is located at the end of the guide rail 521 and is used to change the direction of the filament fed by the first guide wheel 522; the third guide wheel 524 is located between the second guide wheel 523 and the tensioner 53, with multiple third guide wheels 524 arranged in a row to neatly divert and guide the filaments to their respective inlet ends of the tensioner 53. The tensioner 53 is located between the dynamic buffer assembly 52 and the wire guide mechanism 40 and is used to perform final precision tension adjustment on the filaments before they enter the wire guide mechanism 40. The dynamic buffer assembly 52 is responsible for absorbing large speed fluctuations, and the tensioner 53 is responsible for the final fine tension adjustment. The two work together to ensure that the tension of the wire entering the wire guide mechanism 40 is stable and controllable.
[0034] like Figure 1 , Figures 6 to 8As shown, the lead wire mechanism 40 receives multiple filaments from the feeding mechanism 50 and precisely guides them to the winding mechanism 10. The lead wire mechanism 40 includes a three-axis moving module 41 and an anti-skid assembly 42, a guide needle assembly 43, and a cutting clamp assembly 44 mounted on the three-axis moving module 41. The three-axis moving module 41 is used to drive the above-mentioned components to move in multiple degrees of freedom to realize actions such as lead wire, repositioning, and auxiliary cutting. Specifically, the three-axis moving module 41 includes a first transverse moving assembly 411, a lifting assembly 412, a second transverse moving assembly 413, and a third transverse moving assembly 414. Among them, the first transverse moving assembly 411 moves along a first horizontal direction; the lifting assembly 412 is disposed on the first transverse moving assembly 411 and moves along a vertical direction; the second transverse moving assembly 413 and the third transverse moving assembly 414 are both disposed on the lifting assembly 412 and are parallel to each other, both moving along a second horizontal direction perpendicular to the first horizontal direction. The second lateral movement component 413 and the third lateral movement component 414 can be driven independently to achieve asynchronous operation of the anti-jump wire component 42, the guide pin component 43 and the cutting clamp component 44.
[0035] The anti-skid wire component 42 is used to prevent extremely fine wires from jumping off the predetermined path during wiring. For example... Figure 7 As shown, the anti-jump wire assembly 42 includes a first mounting base 423 and a plurality of spaced-apart anti-jump wire devices 421. The first mounting base 423 is fixedly connected to the second lateral movement assembly 413. The first mounting base 423 has a plurality of through-holes 422 for wires, and an anti-jump wire device 421 is provided above each wire hole 422. Each anti-jump wire device 421 is hinged to the first mounting base 423 by a mounting plate, allowing the anti-jump wire device 421 to rotate relative to the first mounting base 423. This adapts to the dynamic changes in the wire's travel angle during the wire introduction process, reducing friction between the wire and the anti-jump wire device 421 and lowering the risk of wire breakage. Each anti-jump wire device 421 has a guide hole or guide groove for the wire to pass through. After the wire exits from the wire hole of the tensioner 53, it first passes through the anti-jump wire device 421 and then passes downward through the corresponding wire hole 422 on the first mounting base 423.
[0036] like Figure 6 and Figure 8As shown, the guide pin assembly 43 is located below the anti-skid assembly 42, and includes a second mounting base 432 and a plurality of spaced hollow guide pins 431. The hollow guide pins 431 are disposed through the second mounting base 432, with their inlet and outlet ends extending out from the upper and lower sides of the second mounting base 432, respectively. The hollow guide pins 431 are inverted conical in shape, with the inner diameter of the inlet end being larger than the inner diameter of the outlet end. The larger diameter of the inlet end facilitates the insertion of extremely fine wires, while the smaller diameter of the outlet end allows for precise control of the outlet position. The first mounting base 423 and the second mounting base 432 are fixedly connected by a connecting bracket, ensuring that the anti-skid device 421 and the hollow guide pins 431 correspond one-to-one in the vertical direction. After passing through the lead hole 422, the fine wire enters the hollow guide pin 431 directly below, thus forming a continuous wire passage and ensuring that the extremely fine wire maintains a stable wire path before entering the winding mechanism 10.
[0037] like Figure 6 and Figure 8 As shown, the shearing clamp assembly 44 is located on one side of the guide pin assembly 43, including a third mounting base 442 and a plurality of spaced-apart pneumatic shearing elements 441. The third mounting base 442 is fixedly connected to the third lateral movement assembly 414, and the plurality of pneumatic shearing elements 441 are located on the side of the third mounting base 442, with each pneumatic shearing element 441 corresponding to a specific position of each hollow guide pin 431. It should be noted that the pneumatic shearing element 441 has both wire cutting and clamping functions: it performs a cutting action when the wire needs to be cut, and clamps the wire end after cutting or during wire lead-out to prevent the wire end from retracting or falling off, thus preparing for the next wire lead-out. Since the anti-skid assembly 42 and the guide pin assembly 43 are driven by the second lateral movement assembly 413, and the shearing clamp assembly 44 is driven by the third lateral movement assembly 414, their independent driving allows the guide pin assembly 43 and the shearing clamp assembly 44 to be in different working positions during wire lead-out and winding processes, without interfering with each other and forming a cooperative working relationship.
[0038] The filament guided by the lead-in mechanism 40 is finally fed to the winding mechanism 10 for winding. For example... Figures 1 to 3As shown, the winding mechanism 10 includes a winding body 11, a first rotary drive 12, and a wire end fixing assembly 13. The winding body 11 is formed by multiple winding plates 111. In this embodiment, the winding plates 111 are four rectangular plates, forming a cuboid winding body. It should be noted that the number of winding plates 111 is not limited to four; it can be set to three, six, or other numbers according to actual needs, and the number of adhesive application assemblies 22 can be adjusted accordingly. The shape of the winding body 11 is not limited to a cuboid; it can also be a polygonal prism or other shapes suitable for winding. A rotating shaft 112 passes through the inside of the winding body 11. The rotating shaft 112 is supported on the support frames at both ends by bearing seats. The first rotary drive 12 is connected to one end of the rotating shaft 112 and is used to drive the winding body 11 to rotate around its own axis, winding the filaments onto the surface of each winding plate 111.
[0039] A gap exists between two adjacent winding plates 111, and a wire end fixing component 13 is provided at one of the gaps to fix the starting end of the winding. Furthermore, multiple winding stations can be provided on the winding body 11, with multiple wire end fixing components 13 spaced axially at the same gap on the winding body 11. A winding station is defined between two adjacent wire end fixing components 13, thereby dividing the winding body 11 axially into multiple independent winding stations. Each winding station corresponds one-to-one with multiple feeding stations of the feeding mechanism 50, enabling simultaneous winding at multiple stations. The specific number of winding stations can be configured according to product specifications.
[0040] like Figure 3 As shown, the wire end fixing assembly 13 includes a fixing base 131, a fixing block 132, and an elastic reset member 133. The fixing base 131 has a guide groove 134, and the fixing block 132 is embedded in the guide groove 134 and can slide up and down along the guide groove 134. The elastic reset member 133 is located in the guide groove 134, with its upper end abutting against the fixing block 132 and its lower end supported on a support structure below the fixing base 131. It applies an upward elastic preload to the fixing block 132, keeping it in the upper position of the guide groove 134 in its natural state. When the fixing block 132 is subjected to a downward external force, the elastic reset member 133 is compressed, and the fixing block 132 sinks along the guide groove 134, causing the wire end wrapped around the protrusion 1321 to automatically detach. After the external force is removed, the elastic reset member 133 pushes the fixing block 132 upward to reset. In this embodiment, the elastic reset member 133 is a compression spring. The top of the fixing block 132 is provided with a plurality of protrusions 1321 for winding and fixing fine wires. The plurality of protrusions 1321 are arranged at intervals along the axial direction of the winding body 11. In this embodiment, each fixing block 132 is provided with three protrusions 1321 to form three winding fixing ends.
[0041] In actual operation, the initial work cycle can be manually or automatically fixed to the protrusion 1321. In subsequent work cycles, the three-axis moving module 41 of the lead wire mechanism 40 drives the guide needle assembly 43 to guide the filament to the filament fixing assembly 13. The cutting clamp assembly 44 clamps the filament and, in conjunction with the movement of the guide needle assembly 43, the filament is initially fixed on one of the protrusions 1321. Then, the filament is pulled to wind around the three protrusions 1321 in a figure-eight shape, thereby firmly fixing the filament end to the filament fixing assembly 13.
[0042] It should be noted that the other three gaps may optionally be provided with arc-shaped transition pieces. The arc-shaped transition pieces have arc-shaped surfaces to guide the wire and tape to transition smoothly between adjacent winding plates 111, so as to prevent the extremely fine wire and tape from being scratched or folded at the corners of the winding plates 111.
[0043] After the winding is completed, the adhesive application mechanism 20 engages under the drive of the adhesive application moving module 30. For example... Figure 1 and Figure 9 As shown, the adhesive application moving module 30 includes a support plate 31, a linear guide rail 32, a mounting bracket 33, and an adhesive application lateral movement drive 34. The linear guide rail 32 is laid along the axial direction of the winding body 11. The support plate 31 is slidably connected to the linear guide rail 32, and the mounting bracket 33 is fixed to the support plate 31. The adhesive application mechanism 20 is connected to the adhesive application lateral movement drive 34 through the connection with the mounting bracket 33. The adhesive application lateral movement drive 34 drives the support plate 31 to slide back and forth along the linear guide rail 32, thereby driving the entire adhesive application mechanism 20 to move back and forth along the axial direction of the winding body 11. It should be noted that the specific structure of the adhesive application moving module 30 is not limited to the form of a linear guide rail and a support plate. In other embodiments, a screw and nut mechanism, a synchronous belt mechanism, or other linear drive mechanisms can also be used. When the winding mechanism 10 performs the winding action, the adhesive applicator 20 is driven by the adhesive applicator moving module 30 to move to one side of the winding area to avoid interfering with the winding action; after the winding is completed, the adhesive applicator 20 is driven by the adhesive applicator moving module 30 to move back to the winding area.
[0044] like Figure 1 and Figure 4 As shown, the adhesive application mechanism 20 includes a hollow support 21 and multiple sets of adhesive application components 22 disposed thereon. The hollow support 21 is a ring-shaped or prismatic frame structure, arranged on the outer periphery of the winding body 11. In this embodiment, there are four sets of adhesive application components 22, each corresponding to one of the four winding plates 111. The four sets of adhesive application components 22 can be set independently but move synchronously, so as to synchronously complete the application, cutting and winding of the wire on the surface of the four winding plates 111 in one axial reciprocating stroke of the adhesive application mechanism 20.
[0045] Optionally, a fan assembly 23 may also be provided on the hollow bracket 21. The fan assembly 23 includes a high-speed DC fan and an air duct 231 connected thereto, for providing airflow to the adhesive application area to eliminate static electricity or dust that may be generated during the adhesive application process. In cases where dust or waste needs to be adsorbed, the fan assembly 23 may also be configured to be installed in reverse to provide suction.
[0046] like Figure 5 As shown, each adhesive application assembly 22 includes an adhesive dispensing drum 221, an adhesive take-up drum 222, a first pressure roller 223, a second pressure roller 224, and a cutting assembly 225. The adhesive dispensing drum 221 carries and releases unused tape rolls. It includes a detachable drum sleeve on which the tape roll is fitted, allowing for easy replacement of the tape roll by changing the drum sleeve. The adhesive take-up drum 222 recovers tape with attached wire strips, winding it into a multi-layered wire-tape composite roll. Multiple fixing buckles are located near the edge on its central axis to secure the starting end of the finished roll. The centers of the adhesive dispensing drum 221 and the adhesive take-up drum 222 are approximately on the same horizontal line. They are fixedly connected by a connecting plate to ensure relative positional stability, and each is connected to a rotary drive component, used for actively releasing the tape and cooperating in recovering tape with attached wire strips, respectively. Their coordinated operation ensures stable tension on the tape.
[0047] The first pressure roller 223 and the second pressure roller 224 are spaced apart along the conveyor belt direction. The first pressure roller 223 is connected to a first lifting drive 2231, and the second pressure roller 224 is connected to a second lifting drive 2241, so that both the first pressure roller 223 and the second pressure roller 224 can be lifted and lowered independently. The first pressure roller 223 is used to press the conveyor belt onto the wire layer already wound on the surface of the winding plate 111, and the second pressure roller 224 is used to press and fix the cut wire flat strip onto the conveyor belt.
[0048] The rolling cutter assembly 225 is located between the first pressure roller 223 and the second pressure roller 224, and includes a cutter 2251 and a cutting drive 2252 for driving the cutter 2251 to move up and down. In this embodiment, the cutter 2251 is a circular rolling blade, which cuts the wire by rolling to reduce pulling and damage to the wire. Preferably, each adhesive bonding assembly 222 has one cutter 2251 in its rolling cutter assembly 225, which cuts once on each winding surface, so that the cut wire forms a flat strip, while the wire at the gap of the winding plate 111 remains continuous, without generating waste. The cutting position of the cutter 2251 is located above the surface of the winding plate 111, so that the length of the flat strip cut on each winding surface is less than the width of the winding surface.
[0049] Optionally, in other embodiments, the rolling cutter assembly 225 may also be equipped with multiple cutters 2251. These cutters 2251 are arranged parallel to each other at intervals perpendicular to the tape's conveying direction. Each cutter 2251 may share the same cutting drive 2252 or be equipped with an independent cutting drive 2252, completing multiple cuts in a single action to accommodate different flat tape length requirements. For example, when two cutters 2251 are provided, a suction tube can be added to each adhesive application assembly 22 to absorb waste thread segments generated between the two cutters; when three cutters 2251 are provided, two flat tape segments of different lengths can be cut in one operation. The specific number of cutters 2251 can be configured according to product specifications, including but not limited to one, two, or three.
[0050] The tape travels along the following path in each adhesive application assembly 22: after being drawn out from the tape output roll 221, it passes sequentially through the first pressure roller 223, the cutting station where the rolling cut assembly 225 is located, and the second pressure roller 224, and is finally wound up by the tape take-up roll 222.
[0051] The following describes the overall working process of the fine wire winding machine in this embodiment, taking into account the collaborative relationship between the aforementioned institutions.
[0052] During operation, multiple feeding stations of the feeding mechanism 50 simultaneously supply wires. Each wire passes through the active unwinding assembly 51, the dynamic buffer assembly 52, and the tensioner 53 in sequence, and then enters the lead wire mechanism 40 with stable tension. In the lead wire mechanism 40, the wires pass through the anti-skip wire device 421 on the first mounting base 423 of the anti-skip wire assembly 42, the lead wire hole 422 on the first mounting base 423, and the hollow guide needle 431 on the second mounting base 432 of the guide needle assembly 43 in sequence. The three-axis moving module 41 simultaneously guides each wire to the wire end fixing assembly 13 of the winding mechanism 10. The cutting clamp assembly 44 clamps the wire end, and in conjunction with the movement of the guide needle assembly 43, the wire end is wound and fixed on the protrusion 1321 of each fixing block 132.
[0053] After the wire ends are fixed, the lead wire mechanism 40 retracts, and at the same time, the adhesive applicator 20 is driven by the adhesive applicator moving module 30 to retract to one side. The first rotary drive 12 drives the winding body 11 to rotate, and in conjunction with the movement of the three-axis moving module 41, the fine wires are evenly wound and laid on the surface of each winding plate 111 at the corresponding winding station, completing the winding of one layer of wire.
[0054] After the winding is completed, the adhesive application moving module 30's adhesive application lateral movement drive 34 drives the bearing slide plate 31 to slide along the linear guide rail 32, and drives the adhesive application mechanism 20 to move to the winding area through the mounting bracket 33. Each adhesive application assembly 22 operates synchronously: the first pressure roller 223 presses down under the drive of the first lifting drive 2231, pressing the tape released from the adhesive roll 221 onto the wound wire layer; as the adhesive application mechanism 20 moves axially, the cutter 2251 of the rolling cutter assembly 225 performs a cutting action under the drive of the cutting drive 2252, cutting the wire pressed against the surface of the winding plate 111 to form a flat strip; then the second pressure roller 224 presses down under the drive of the second lifting drive 2241, pressing and fixing the cut wire flat strip onto the tape; the take-up roll 222 takes up the tape with the wire attached under the drive of the rotation drive.
[0055] The winding and adhesive application processes described above are repeated multiple times, forming a multi-layered composite strip material roll with alternating layers of wire and adhesive tape on each take-up roll 222. During one axial reciprocating stroke, the adhesive application mechanism 20 simultaneously completes the adhesive application, cutting, and winding of the wire at all winding stations, producing multiple sections of finished flat strip in a single operation.
[0056] After a complete work cycle, the guide pin assembly 43 of the lead-in mechanism 40 moves downward under the drive of the three-axis moving module 41, applying downward pressure to the fixing blocks 132 of each wire end fixing assembly 13. The fixing blocks 132 overcome the elastic preload of the elastic reset member 133 and sink along the guide groove 134, causing the wire end wrapped on the protrusion 1321 to automatically detach. After the external force is removed, the elastic reset member 133 pushes the fixing blocks 132 upward to reset, preparing for the next work cycle, thus realizing fully automated continuous operation of wire end fixing and unloading. The coordinated actions of the above mechanisms are all coordinated and controlled by the control module 60, and the operator sets parameters and monitors the equipment operating status through the operation display screen.
[0057] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
