Description

Technical Field

[0001] This invention belongs to the field of soldering equipment technology, specifically a wire conveying device for connecting wire soldering equipment. Background Technology

[0002] The wire conveying device of the connector soldering equipment consists of several core components that work together to form the basic structure for wire conveying operations. The soldering unit is the main carrier of the equipment, with a fixed support and wire reel rack on top. The support is used to securely install the wire drawing machine, which provides stable traction power for wire conveying. The wire reel rack is used to hold the wire stock rolls, enabling continuous and orderly feeding. Side support plates and bases are fixed to the sides of the support, which can securely mount the wire bundler. The wire bundler can limit, tighten, and guide the conveyed wire, effectively preventing deviation, shaking, and tangling during wire conveying, ensuring the trajectory and positioning accuracy of the wire. The soldering equipment is compatible with automatic and semi-automatic electric arc and plasma arc welding processes, and can continuously complete wire conveying and welding operations. After the wire is in place, the corresponding welding mode can be selected according to the wire specifications and process requirements. The high-energy arc current generated by the welding equipment rapidly fuses and solidifies the connector joint.

[0003] Chinese patent CN209647936U discloses a wire transmission mechanism for a connecting wire soldering device, including a power unit mounted on the device mounting plate and a transmission chain with a wire conveying fixture. The fixture itself can complete the bending work through the rotational engagement of the conductor processing part and the insulation positioning part on the fixture with a pin and a torsion spring. It can perform both horizontal and vertical soldering. As long as the torsion springs are properly matched, the processing can be adjusted at any angle.

[0004] Chinese patent CN110014253B discloses a bimetallic component welding machine, including a base plate, a turntable on the base plate, a clamp on the turntable, and a bimetallic feeding mechanism near the outer periphery of the turntable for transferring bimetallic sheets to the clamp. This machine enables automatic welding of bimetallic sheets, copper wires, lever plastic parts, and moving contacts, improving work efficiency and ensuring welding quality, making it suitable for long-term enterprise development.

[0005] Existing wire conveying equipment for connecting wires typically uses straightening rollers composed of multiple staggered rollers to eliminate bending deformation by squeezing and straightening the wire. However, in large-scale continuous production, the straightening rollers squeezing the wire can cause the flux and other materials pre-coated on the wire surface to break off and adhere to the wire surface. At the same time, the movement of the straightening rollers and the wire generates friction, constantly producing static electricity. This static electricity is difficult to conduct to the ground and accumulates on the surface, attracting fine dust, fibers, metal shavings, and other impurities from the environment. When the wire with these impurities enters the soldering process, the impurities mix with the molten solder, causing slag inclusions, porosity, and microcracks inside the solder joint, reducing the electrical connection reliability and vibration resistance of the solder interface. In the small-pitch soldering of precision electronic connecting wires, even tiny impurities can cause intermittent poor contact, leaving hidden quality problems in the end product that are difficult to detect. If electrostatically attracted conductive particles overlap between adjacent wire cores or pads, they can create abnormal leakage paths or direct short circuits, causing product malfunctions. In addition, under certain conditions, instantaneous discharge of static electricity may also break down sensitive electronic components connected to the wire ends, causing direct damage. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention proposes a wire conveying device for wire soldering equipment. This invention primarily addresses the problems of insufficient wire cleanliness and welding defects caused by the coupling of straightening powder removal and electrostatic adsorption during wire conveying.

[0007] The technical solution adopted by this invention to solve its technical problem is: a wire conveying device for a connecting wire soldering equipment, including a soldering device and a wire drawing machine disposed on its top; a base is disposed on the top of the wire drawing machine, and at least three support frames are detachably disposed on the inner side of the base, with a straightening wheel rotatably connected to the inner side of each support frame; a cleaning component is disposed on the top of the support frame near the bottom of the base, and an anti-static component is disposed on the bottom of the support frame near the bottom of the base; the cleaning component includes a cleaning element connected to the top of the straightening wheel via a gear set; after the wire is straightened by the straightening wheel, the cleaning element uses the force of the straightening wheel's rotation to wipe the wire with constant pressure and full circumferential contact; simultaneously, the straightening process may crush out... Tiny flux powders are immediately removed at the rear to ensure that the welding wire entering the conduit is absolutely clean. The static electricity removal assembly includes protrusions fixed to both sides of the straightening wheel, a sliding plate slidably engaged on the inner side of the support frame, a contact rod on the inner side of the sliding plate, and an elastic element connecting the sliding plate and the support frame. The protrusions, in conjunction with the elastic element, cause the sliding plate to move along the direction of the straightening wheel as the straightening wheel rotates, driving the contact rod to intermittently contact the wire to discharge static electricity. After straightening and cleaning, the contact rod can contact the wire with stable pressure, forming a reliable static electricity discharge path. In addition, cleaning before static electricity removal can prevent the static-charged welding wire from attracting lint and dust floating in the air during the cleaning process.

[0008] Furthermore, the rotation axes of each straightening wheel are parallel to each other and horizontally arranged, and the axes of each straightening wheel are staggered in the horizontal direction to force the welding wire to form an S-shaped bending path.

[0009] Furthermore, one end of the support frame is connected to an adjusting rod via a thread, and the other end of the adjusting rod is rotatably connected to a wheel frame. The straightening wheel is rotatably connected to the inner side of the wheel frame, and the wheel frame is slidably engaged with the inner side of the support frame. The support frame is connected to the base via bolts. The number of support frames can be adjusted according to the amount of wire. The adjusting rod and the wheel frame work together to adjust the position of the straightening wheel, thereby changing the straightening depth.

[0010] Furthermore, a horizontal plate 1 and a horizontal plate 2 are detachably connected to the top of the support frame near the bottom of the base. The horizontal plate 1 is located on the side of the horizontal plate 2 near the opening end of the support frame. The gear set includes a driven wheel rotatably connected to the inner side of the horizontal plate 1, a secondary bevel gear rotatably connected to the inner side of the horizontal plate 2, a main bevel gear fixed to the outer side of the straightening wheel, and a driving wheel fixed to the top of the secondary bevel gear. The secondary bevel gear and the main bevel gear mesh, and the driving wheel and the driven wheel mesh.

[0011] Furthermore, a cleaning component is fixed to the inside of the driven wheel. The cleaning component is made of high-density wool felt or microporous sponge. When the wire drawing machine pulls the wire, the wire drives the straightening wheel to rotate. The straightening wheel drives the cleaning component to rotate through the gear set to clean the wire.

[0012] Furthermore, a limit rod is fixed to the inner side of the bottom of the support frame near the base, and the sliding plate is slidably engaged with the outer side of the limit rod. One end of the elastic element is fixedly connected to the support frame, and the other end of the elastic element is fixedly connected to the sliding plate. A limit block is fixed to the outer side of the limit rod. The limit block is used to prevent the sliding plate from colliding or rubbing against the straightening wheel.

[0013] Furthermore, the contact rod is slidably connected to the inner side of the sliding block, and a connecting plate is fixed to the outer side of both contact rods. An elastic element II is fixed to the side of each connecting plate near the sliding plate, and the other end of each elastic element II is fixedly connected to the sliding plate. The elastic element II is used to prevent the contact rod from excessively squeezing the wire.

[0014] Furthermore, a bracket is fixed to the top of the soldering device, a wire pulling machine is fixed to the inside of the bracket, a wire reel is fixed to the top of the soldering device, a support plate is fixed to one side of the bracket, a base is fixed to the top of the support plate, and a wire bundler is fixed to the inside of the support plate.

[0015] The beneficial effects of this invention are as follows: 1. In this invention, the straightening rollers apply continuous bending and counter-bending to the wire using an alternating S-shaped path, gradually eliminating its original bending deformation and restoring the wire to straightness. This provides a foundation for subsequent precise conveying and positioning. Simultaneously, the straightening and rolling action loosens and removes flux powder adhering to the wire surface. The cleaning component directly utilizes the rotation of the straightening rollers as a power source, driving a high-density wool felt or microporous sponge cleaning element to wipe the wire with constant pressure in a full circumference, instantly and thoroughly removing the loosened powder and preventing it from entering the welding area and forming inclusions or pores. Following the cleaning process, the antistatic component is driven by protrusions and elastic elements. The contact rod makes periodic, intermittent contact with the wire, reliably dissipating the static charge accumulated during straightening and cleaning. The sequential design of cleaning before destatication prevents the clean wire with static electricity from re-adsorbing dust from the air. At the same time, the elastic buffer mechanism ensures that the contact pressure is moderate and does not damage the wire surface. The straightening, dust removal, wiping, and static elimination purification chain formed by these three elements ensures that the welding wire entering the welding area is highly clean, straight, and free of static electricity. This effectively improves the welding positioning accuracy and arc stability, suppresses defects such as spatter and incomplete welding, and ultimately obtains a uniform and strong weld joint, significantly reducing the post-weld rework rate and providing a reliable prerequisite for high-speed precision welding.

[0016] 2. In this invention, the cleaning component obtains rotational power from the straightening wheel via a gear set, eliminating the need for an additional motor drive. This results in a compact and energy-efficient structure. The transmission chain, consisting of the main bevel gear, secondary bevel gear, driving wheel, and driven wheel, converts the rotation of the straightening wheel into the rotational motion of the cleaning component. Made of high-density wool felt or microporous sponge, the cleaning component softly and tightly wraps around the entire circumference of the wire, applying constant pressure to wipe the moving wire. Flux powder loosened by the crushing process during straightening is immediately removed by the cleaning component, preventing powder accumulation on the wire surface or introduction into subsequent guide tubes and welding torches. This eliminates the risk of flux overheating and carbonization during welding, which can produce black smoke, spatter, or slag inclusions in the weld. Simultaneously, the continuous rotation of the cleaning component refreshes the contact surface, ensuring long-term stability of the wiping effect and maintaining a high degree of cleanliness on the welding wire surface. This is particularly crucial for precision welding processes that rely on the surface condition of the welding wire, significantly improving the first-pass yield of welds. Furthermore, this cleaning method is purely mechanical and does not introduce electrical interference, further ensuring the purity of the welding environment.

[0017] 3. In this invention, the static electricity removal component is positioned after the cleaning process, forming a reasonable sequence of cleaning first and then static electricity removal. This prevents the clean wire from re-adsorbing airborne lint and dust under electrostatic attraction. The protrusions on the side of the straightening wheel periodically push the sliding plate as the wheel rotates, causing the contact rod to reciprocate linearly under the action of the elastic element. The contact rod only lightly touches the wire surface to discharge static electricity when the protrusions push. During the wire pulling process, the contact rod remains separated, avoiding wear at the contact end caused by long-term sliding friction and significantly extending the service life of the contact rod. The rear end of the contact rod is equipped with an elastic element for floating buffering. When the contact rod contacts the wire, it can adaptively adjust the pressure, ensuring reliable conduction of static electricity while preventing scratches or plastic deformation on the wire surface due to excessive compression, thus maintaining the original mechanical properties and feeding stability of the welding wire. After this treatment, the wire is in an electrically neutral state before entering the welding zone, eliminating the phenomenon of electrostatic discharge interfering with the arc shape, causing molten pool oscillation or protective gas turbulence. This makes the welding process more stable, with consistent penetration depth, beautiful weld formation, and effectively reducing defects such as porosity and spatter. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 13 As shown, a wire conveying device for a connecting wire soldering equipment includes a soldering device 1 and a wire pulling machine 2 disposed on its top. A bracket 21 is fixed to the top of the soldering device 1, the wire pulling machine 2 is fixed to the inner side of the bracket 21, a wire reel 4 is fixed to the top of the soldering device 1, a support plate 31 is fixed to one side of the bracket 21, a base 3 is fixed to the top of the support plate 31, and a wire bundler is fixed to the inner side of the support plate 31.

[0022] In this embodiment, as Figures 1 to 3 As shown, the connecting wire soldering equipment mainly consists of a soldering device 1, a wire pulling machine 2, and a supporting conveying structure. It is used in conjunction with automatic or semi-automatic electric arc welding machines or plasma arc welding machines to automate the conveying, precise positioning, and welding of connecting wires. The equipment uses a wire reel 4 on top of the soldering device 1 to hold wire reels, ensuring orderly storage and continuous feeding of the raw materials. During operation, the wire pulling machine 2, fixed inside the support 21, serves as the core feeding component, providing stable pulling force and precisely guiding the wire forward. During wire conveying, the wire bundler inside the support plate 31 can regulate, limit, and guide the wire, preventing deviation and tangling, ensuring feeding accuracy and stability. Simultaneously, the support plate 31 and the top base 3 provide stable support for the wire bundling structure, and the support 21 provides a fixed installation point for the wire pulling machine 2, ensuring stable overall equipment operation. After the wire is conveyed and positioned, the equipment switches to the welding process. Depending on the wire processing requirements, either electric arc welding or plasma arc welding can be selected. The corresponding automatic or semi-automatic welding equipment is used to complete the wire butt welding process. The high-energy arc current enables the rapid fusion and forming of the wire joint. The entire device completes the entire process of wire pretreatment and forming welding in a continuous manner through the coordinated cooperation of multiple structures such as feeding, straightening, positioning, and welding. The operation is highly efficient and stable. The above are existing conventional technologies and will not be elaborated further.

[0023] Specifically, the top of the wire drawing machine 2 is provided with a base 3, and at least three support frames 5 are detachably provided on the inner side of the base 3. A straightening wheel 6 is rotatably connected to the inner side of each support frame 5. A cleaning component 7 is provided on the top of the support frame 5 near the bottom of the base 3, and an anti-static component 8 is provided on the bottom of the support frame 5 near the bottom of the base 3. The cleaning component 7 includes a cleaning element 77 connected to the top of the straightening wheel 6 through a gear set. After the wire is straightened by the straightening wheel 6, the cleaning element 77 uses the force of the straightening wheel 6 to wipe the wire with constant pressure and full circumferential contact. At the same time, some tiny flux powder may be crushed out during the straightening process, which is immediately removed behind to ensure that the welding wire entering the guide tube is clean. The rotation axes of each straightening wheel 6 are parallel to each other and horizontally arranged. The axes of each straightening wheel 6 are staggered in the horizontal direction to force the welding wire to form an S-shaped bending path.

[0024] In this embodiment, as Figures 2 to 6 As shown, the operator passes the wire through all the straightening rollers 6 and inserts it into the wire pulling machine 2 via the wire bundler. The operator then controls the wire pulling machine 2 to clamp the wire. The operator then rotates the adjusting rod 52 according to actual needs. The adjusting rod 52, through its meshing with the support frame 5, drives the wheel frame 51 to move along the inner side of the support frame 5. The straightening rollers 6 follow the wheel frame 51, thus adjusting the straightening depth. Adjacent straightening rollers 6 apply a straightening force to the welding wire from both sides of the S-shaped path, gradually correcting the bending deformation of the wire, improving the straightness of subsequent wire feeding, and preventing the bending of the wire from affecting the welding position accuracy. The cleaning component 77 simultaneously utilizes the rotation of the straightening rollers 6 for power, eliminating the need for an additional drive source. When the cleaning component 77 wipes the wire, the static electricity elimination component 8 simultaneously performs static electricity elimination treatment on the cleaned wire, preventing the accumulation of static electricity on the wire surface and adsorbing dust, and also preventing unstable welding due to static interference during the welding process. All support frames 5 can be removed from the inside of the base 3, which makes it easy to adjust the spacing of the straightening rollers 6 to accommodate wires of different diameters, and also facilitates the maintenance and replacement of the cleaning components 77 and the static elimination components 8.

[0025] Specifically, one end of the support frame 5 is connected to an adjusting rod 52 via a thread, and the other end of the adjusting rod 52 is rotatably connected to a wheel frame 51. The straightening wheel 6 is rotatably connected to the inner side of the wheel frame 51, and the wheel frame 51 is slidably engaged with the inner side of the support frame 5. The support frame 5 is connected to the base 3 via bolts. The number of support frames 5 can be adjusted according to the wire material. The adjusting rod 52 and the wheel frame 51 work together to adjust the position of the straightening wheel 6, thereby changing the straightening depth. The tangents of the contact points between the two straightening wheels 6 near the bottom of the base 3 and the wire are parallel to the inlet direction of the wire entering the wire drawing machine 2.

[0026] In this embodiment, as Figures 8 to 10As shown, the worker passes the wire through all the straightening wheels 6 and then inserts it into the wire pulling machine 2 through the wire bundler. The worker then controls the wire pulling machine 2 to clamp the wire. The worker then rotates the adjusting rod 52 according to the actual needs. The adjusting rod 52 drives the wheel frame 51 to move along the inner side of the support frame 5 through the meshing action with the support frame 5. The straightening wheels 6 follow the wheel frame 51 to move, thereby realizing the adjustment of the straightening depth.

[0027] Specifically, a horizontal plate 71 and a horizontal plate 72 are detachably connected to the top of the support frame 5 near the bottom of the base 3. The horizontal plate 71 is located on the side of the horizontal plate 72 near the opening end of the support frame 5. The gear set includes a driven wheel 73 rotatably connected to the inside of the horizontal plate 71, a secondary bevel gear 74 rotatably connected to the inside of the horizontal plate 72, a main bevel gear 75 fixed to the outside of the straightening wheel 6, and a driving wheel 76 fixed to the top of the secondary bevel gear 74. The secondary bevel gear 74 and the main bevel gear 75 mesh, and the driving wheel 76 and the driven wheel 73 mesh. A cleaning component 77 is fixed to the inside of the driven wheel 73. The cleaning component 77 is made of high-density wool felt or microporous sponge. When the wire pulling machine 2 pulls the wire, the wire drives the straightening wheel 6 to rotate. The straightening wheel 6 drives the cleaning component 77 to rotate through the gear set to clean the wire.

[0028] In this embodiment, during the straightening process, the flux powder adhering to the wire surface gradually loosens and falls off due to the continuous rolling of the straightening wheel 6. Simultaneously, the main bevel gear 75, rotating synchronously with the straightening wheel 6, meshes with the secondary bevel gear 74, which in turn drives the top drive wheel 76 to rotate. The drive wheel 76 then meshes with and drives the driven wheel 73, which in turn drives the cleaning component 77 mounted on the inner side to rotate continuously. The cleaning component 77 adheres tightly to the outer surface of the wire with constant pressure, wiping it around its entire circumference during the wire's movement. This effectively removes the flux powder that has fallen off the straightening wheel 6 directly from the wire surface, preventing the powder from entering subsequent processes and causing contamination or affecting welding quality.

[0029] Specifically, the static electricity removal component 8 includes protrusions 85 fixed on both sides of the straightening wheel 6, a sliding plate 81 slidably engaged on the inner side of the support frame 5, and a contact rod 82 provided on the inner side of the sliding plate 81. The contact rod 82 has excellent conductivity, and the other end of the contact rod 82 is grounded. An elastic element 86 is connected between the sliding plate 81 and the support frame 5. The elastic element 86 can be set as a spring or other device capable of radial elasticity. The protrusions 85 cooperate with the elastic element 86 to move the sliding plate 81 along the direction of the straightening wheel 6 by rotating the straightening wheel 6, driving the contact rod 82 to intermittently contact the wire to discharge static electricity. After straightening and cleaning, the contact rod 82 can contact the wire with stable pressure to form a reliable static electricity discharge path. In addition, cleaning before static electricity removal can prevent the static-charged welding wire from adsorbing lint and dust floating in the air during the cleaning process. A limit rod is fixed to the inner side of the bottom of the support frame 5 near the bottom of the base 3. The sliding plate 81 is slidably engaged with the outer side of the limit rod. One end of the elastic element 86 is fixedly connected to the support frame 5, and the other end of the elastic element 86 is fixedly connected to the sliding plate 81. A limit block is fixed to the outer side of the limit rod. The limit block is used to prevent the sliding plate 81 from colliding or rubbing against the straightening wheel 6.

[0030] In this embodiment, as Figures 8 to 13 As shown, the cleaned wire continues to move smoothly forward, entering the working area of ​​the static electricity removal component 8. During the continuous rotation of the straightening wheel 6, the protrusions 85 on the wheel surface periodically push the sliding plate 81. When the protruding part of the protrusion 85 contacts the sliding plate 81, it pushes the sliding plate 81 along the limit rod towards the wire. At this time, the elastic element 86 is gradually compressed and stores energy. When the protruding part of the protrusion 85 moves away from the sliding plate 81, the elastic element 86 releases its elastic force, pulling the sliding plate 81 back to its original position quickly. In this way, the sliding plate 81 drives the contact rod 82 to perform periodic reciprocating motion, causing the contact rod 82 to intermittently contact the surface of the wire. This reliably discharges the static electricity accumulated by friction during the wire's movement to the ground through the contact rod 82 and the main body of the equipment, and prevents the removal of fine powder impurities after static electricity discharge.

[0031] Specifically, the contact rod 82 is slidably connected to the inner side of the sliding block, and a connecting plate 83 is fixed to the outer side of both contact rods 82. An elastic element 84 is fixed to the side of each connecting plate 83 near the sliding plate 81. The elastic element 84 can be set as a spring or other device capable of radial elasticity. The other end of each elastic element 84 is fixedly connected to the sliding plate 81. The elastic element 84 is used to prevent the contact rod 82 from excessively squeezing the wire.

[0032] In this embodiment, the design of the protrusion 85 ensures that the contact rod 82 contacts the wire after one wire pulling operation. During the wire pulling process, the contact rod 82 does not contact the wire, thus preventing sliding friction and extending the service life of the contact rod 82. At the same time, the elastic element 84 can buffer the squeezing force of the contact rod 82 on the wire, preventing excessive squeezing force from causing wire deformation and ensuring the stability of wire transmission and subsequent welding. In addition, the elastic element 84 always presses against the connecting plate 83 and the contact rod 82, ensuring that the contact rod 82 contacts the wire with stable and moderate pressure. This ensures reliable conduction of the electrostatic path and avoids excessive squeezing of the wire due to excessive pressure, which would affect its normal transmission.

[0033] In summary, the straightening roller 6 applies continuous bending and reverse bending to the wire through an interlaced S-shaped path, gradually eliminating its original bending deformation and restoring the wire to a straight state, laying the foundation for subsequent precise conveying and positioning. Simultaneously, the rolling action during straightening loosens and removes flux powder adhering to the wire surface. The cleaning component 7 directly utilizes the rotation of the straightening roller 6 as a power source, driving the high-density wool felt or microporous sponge cleaning element 77 to wipe the wire with constant pressure in a full circumference, instantly and thoroughly removing the loosened powder and preventing it from entering the welding area and forming inclusions or pores. Following the cleaning process, the static eliminator component periodically and intermittently contacts the wire through the protrusions 85 and the contact rod 82 driven by the elastic element, reliably discharging the static charge accumulated during straightening and cleaning. Furthermore, the sequence of cleaning before static eliminator prevents the clean, static-laden wire from re-attracting dust from the air, while the elastic buffer mechanism ensures moderate contact pressure without damaging the wire surface. The straightening, dust removal, wiping, and static elimination purification chain formed by these three components ensures that the welding wire entering the welding area is highly clean, straight, and free of static electricity. This effectively improves welding positioning accuracy and arc stability, suppresses defects such as spatter and incomplete welding, and ultimately obtains a uniform and strong welded joint, significantly reducing the post-weld repair rate and providing a reliable guarantee for high-speed precision welding.

[0034] During operation, the operator passes the wire through all the straightening wheels 6 in sequence, and inserts it into the wire pulling machine 2 after passing through the wire bundler. The operator then controls the wire pulling machine 2 to clamp and fix the wire. Subsequently, the operator rotates the adjusting rod 52 according to the process requirements. The adjusting rod 52 drives the wheel frame 51 to move along the inner side of the support frame 5 through meshing transmission with the support frame 5. The straightening wheels 6 move synchronously with the wheel frame 51, thereby completing the adjustment of the straightening depth.

[0035] During the welding process, the wire drawing machine 2 pulls the wire forward, and the wire drives each straightening wheel 6 to rotate continuously during the conveying process. The straightening wheel 6 adopts a staggered path arrangement. When the wire passes through this structure, it is subjected to continuous and repeated bending and reverse bending. The original bent or distorted parts are gradually corrected and restored to a straight shape.

[0036] During the straightening process, the flux powder adhering to the surface of the wire gradually loosens and falls off under the continuous rolling action of the straightening wheel 6. At the same time, the driving bevel gear, which rotates synchronously with the straightening wheel 6, drives the driven bevel gear to rotate through meshing transmission. The driven bevel gear further drives the upper driving wheel 76 to rotate. The driving wheel 76 drives the driven wheel 73 to rotate through meshing. The driven wheel 73 drives the cleaning component installed on the inner side to rotate continuously. The cleaning component adheres tightly to the outer surface of the wire with constant pressure, and performs a full-circumferential cleaning of its outer surface during the wire's movement.

[0037] After cleaning, the wire is continuously and steadily conveyed forward into the working area of ​​the static elimination component 8. During the continuous rotation of the straightening wheel 6, the protrusions 85 on the wheel surface periodically contact the sliding plate 81: when the protruding part of the protrusion 85 contacts the sliding plate 81, it pushes the sliding plate 81 along the limiting rod towards the wire, at which point the first elastic element is gradually compressed and stores energy; when the protruding part of the protrusion 85 moves away from the sliding plate 81, the first elastic element releases its elastic potential energy, pulling the sliding plate 81 to quickly return to its original position. This process drives the contact rod 82 to perform periodic reciprocating motion, causing the contact rod 82 to intermittently contact the wire surface.
