Description

Technical Field

[0001] The present application relates to the technical field of copper alloy wire production, and in particular to a copper alloy wire production line and production method. Background Art

[0002] Copper alloy wire boasts high strength, hardness, electrical conductivity, and thermal conductivity, offering broad development prospects in industries such as automotive, electrode wire, and high-energy battery manufacturing. The typical copper alloy wire production line process includes smelting and alloying, continuous casting, drawing, annealing, and surface treatment.

[0003] During the copper alloy wire production process, work hardening requires annealing, which forms a layer of oxide scale on the wire's surface. Currently, the conventional method for removing this scale is to use an acid wash solution followed by saponification. The use of hydrochloric acid or sulfuric acid solutions produces residual phosphorus slag, wastewater, and sludge, which can seriously pollute the environment. Prolonged exposure to hydrochloric acid wash solutions can easily lead to respiratory, skin, and mucous membrane poisoning, severely harming the health of workers. Summary of the Invention

[0004] The embodiments of the present application provide a copper alloy wire production line and production method, which can improve the technical problems in the related art of copper alloy wire production that cause environmental pollution and damage to human health due to the need to use chemical products to remove oxide scale.

[0005] In a first aspect, an embodiment of the present application provides a copper alloy wire production line, comprising:

[0006] Pay-off rack;

[0007] A conductor mechanism, located at the output side of the pay-off frame, for transmitting the copper alloy wire input by the pay-off frame;

[0008] a peeling assembly, located at the output side of the conductor mechanism, for removing oxide scale from the surface of the copper alloy wire input by the conductor mechanism; and

[0010] In which, the peeling assembly includes two driving mechanisms and a grinding mechanism, one of the driving mechanisms is connected to the output side of the wire mechanism, and the other driving mechanism is located on the input side of the cleaning mechanism.

[0061] Copper alloy wire boasts high strength, hardness, electrical conductivity, and thermal conductivity, offering broad development prospects in industries such as automotive, electrode wire, and high-energy battery manufacturing. The typical copper alloy wire production line process includes smelting and alloying, continuous casting, drawing, annealing, and surface treatment.

[0062] During the copper alloy wire production process, work hardening requires annealing, which forms a layer of oxide scale on the wire's surface. Currently, the conventional method for removing this scale is to use an acid wash solution followed by saponification. The use of hydrochloric acid or sulfuric acid solutions produces residual phosphorus slag, wastewater, and sludge, which can seriously pollute the environment. Prolonged exposure to hydrochloric acid wash solutions can easily lead to respiratory, skin, and mucous membrane poisoning, severely harming the health of workers.

[0063] Based on this, in order to improve the problem of environmental pollution and damage to human health caused by the need to use chemical products to remove oxide scale during the production of copper alloy wire in the related art, the embodiments of the present application provide the following solution.

[0064] See also Figure 1 The present invention provides a copper alloy wire production line 100, comprising a pay-off frame 10, a conductor mechanism 20, a peeling assembly 30, and a cleaning mechanism 40. The conductor mechanism 20 is located at the output side of the pay-off frame 10 and is used to transport the copper alloy wire 200 input by the pay-off frame 10. The peeling assembly 30 is located at the output side of the conductor mechanism 20 and is used to remove oxide scale from the surface of the copper alloy wire 200 input by the conductor mechanism 20. The cleaning mechanism 40 is located at the output side of the peeling assembly 30 and is used to clean the peeled copper alloy wire 200 output by the peeling assembly 30.

[0065] The peeling assembly 30 includes two drive mechanisms 31 and a grinding mechanism 32. One drive mechanism 31 is connected to the output side of the wire guide mechanism 20, and the other drive mechanism 31 is located on the input side of the cleaning mechanism 40. The drive mechanism 31 is used to drive the copper alloy wire 200 to rotate around the centerline of the grinding mechanism 32. The grinding mechanism 32 is located between the two drive mechanisms 31 and is used to grind the copper alloy wire 200 after it is output from one of the drive mechanisms 31.

[0066] It can be understood that the wire mechanism 20 is a device for suspending and supporting the direction of the copper alloy wire. The wire mechanism 20 can be various types of structures, such as a suspension wire mechanism, a vibration-proof wire mechanism, and a tension-adjusting wire mechanism, but is not limited thereto.

[0067] The peeling assembly 30 is used to remove the oxide scale formed on the surface of the copper alloy wire 200. The drive mechanism 31 and the grinding mechanism 32 are components of the peeling assembly 30 and serve as the specific actuators. The drive mechanism 31 is used to rotate the copper alloy wire and can be a transmission device of various structures, such as, but not limited to, a gear drive or a belt drive. The grinding mechanism 32 is used to grind the oxide scale on the surface of the copper alloy wire 200 and can be a variety of structures, such as, but not limited to, a belt grinder, a grinding wheel grinder, and a brush grinder.

[0068] During the annealing process, the copper alloy wire 200 is heated at high temperature, and the surface of the copper alloy wire 200 will be oxidized, resulting in the formation of oxide scale. The oxide scale may affect the electrical conductivity and connection performance, so in practical applications, it is necessary to clean or remove the oxide scale. From the above, it can be seen that the copper alloy wire production line 100 provided in the embodiment of the present application, when the copper alloy wire needs to be surface treated, the copper alloy wire 200 is first paid out by the pay-off frame 10, and then the copper alloy wire 200 output by the pay-off frame 10 is transmitted by the conductor mechanism 20. During the transmission of the copper alloy wire 200, the conductor mechanism 20 can reduce the stress concentration and fatigue damage of the copper alloy wire 200, play a buffering and absorption role, make the force on the copper alloy wire 200 more uniform, and improve the safety, reliability and service life of the copper alloy wire 200. When the copper alloy wire 200 is transmitted to the peeling component 30, the two drive mechanisms 31 simultaneously perform circumferential rotation motion, thereby driving the copper alloy wire 200 passing through the two drive mechanisms 31 to rotate. One of the drive mechanisms 31 transfers the copper alloy wire 200 to the polishing mechanism 32. Since the polishing mechanism 32 is located between the two drive mechanisms 31, when the two drive mechanisms 31 drive the copper alloy wire 200 to rotate circumferentially around the centerline of the polishing mechanism 32, the polishing mechanism 32 scrapes or rubs the surface of the copper alloy wire, causing the copper alloy wire 200 to rotate while being transported forward, thereby removing the surface oxide scale. Compared to the method of directly using a polishing component to polish the copper alloy wire 200 that only moves linearly (parts of the copper alloy wire 200 may not be polished), this method can effectively improve the comprehensiveness and uniformity of the polishing, thereby effectively removing surface defects such as oxide scale and rust, making the copper alloy wire surface smooth and uniform. If oxide scale or impurities and dust adhere to the surface of the polished copper alloy wire 200, the other drive mechanism 31 transfers the polished copper alloy wire 200 to the cleaning mechanism 40 for cleaning.

[0069] In some embodiments, see Figure 1 The wire mechanism 20 includes a wire assembly 21 and a wire feed adjustment assembly 22. The wire assembly 21 is located on the output side of the pay-off frame 10. The wire feed adjustment assembly 22 is located between the output side of the wire assembly 21 and the input side of one of the drive mechanisms 31. It is used to adjust the tension of the copper alloy wire 200 input to one of the drive mechanisms 31 and to ensure that the copper alloy wire 200 is aligned with the rotation centerline of one of the drive mechanisms 31.

[0070] It is understood that the conductor assembly 21 is used to guide the copper alloy wire 200 to maintain the correct direction and position during transmission. The conductor assembly 21 can be various types of guide structures, such as a slow stop wheel assembly, a guide wheel assembly, and a support wheel assembly, but is not limited thereto.

[0071] The wire feed adjustment assembly 22 is used to adjust the tension of the copper alloy wire 200 and can be various types of adjustment mechanisms, for example, it can include an adjustment wheel.

[0072] With such an arrangement, the conductor assembly 21 transmits the copper alloy wire 200 to one of the driving mechanisms 31. When the driving mechanism 31 drives the copper alloy wire 200 to rotate circumferentially around the center line of the driving mechanism 31, the copper alloy wire 200 generates corresponding tensile stress. The wire feed adjustment assembly 22 is used to adjust the tensile stress generated by the copper alloy wire 200 during the transmission process, which is beneficial to alleviate the wear of the copper alloy wire 200 due to force during the transmission process; during the circumferential rotation of the copper alloy wire 200, the wire feed adjustment assembly 22 can also adjust the corresponding height of the copper alloy wire according to the direction of the copper alloy wire 200, so that the copper alloy wire 200 and the rotation center line of the driving mechanism 31 are always kept at the same horizontal position during the transmission process, which is beneficial to improve the stability of the circumferential rotation movement of the copper alloy wire 200 around the center line of the driving mechanism 31, and thus help improve the polishing effect.

[0073] In some embodiments, see Figure 2 The driving mechanism 31 includes a support frame 311, a driving part 312, a transmission assembly 313 and a rotating ring 314. A cavity is provided inside the support frame 311. The driving part 312 is arranged in the cavity of the support frame 311. The transmission assembly 313 is arranged on the support frame 311. The power output end of the driving part 312 is connected to the transmission assembly 313. The rotating ring 314 is in transmission cooperation with the transmission assembly 313, and a wire inlet pipe 315 for passing the copper alloy wire 200 is provided on the inner side wall of the rotating ring 314. The center line of the rotating ring 314 is collinear with the center line of the grinding mechanism 32, and the center line of the wire inlet pipe 315 deviates from the center line of the rotating ring 314.

[0074] It can be understood that the transmission assembly 313 can be various types of transmission mechanisms, such as a gear transmission mechanism, a belt transmission mechanism, etc., but is not limited thereto.

[0075] The driving portion 312 is a mechanism for driving the transmission assembly 313 to move. The driving portion 312 may be various types of driving devices, for example, may include a motor.

[0076] The rotating ring 314 is a component for driving the copper alloy wire 200 to rotate, and may be, for example, a ring structure of various types.

[0077] With this arrangement, the power output end of the drive unit 312 drives the transmission assembly 313 to perform a clockwise rotational motion, causing the rotating ring 314, which is coupled to the transmission assembly 313, to rotate counterclockwise, thereby driving the inlet pipe 315 and the copper alloy wire 200 passing through the inlet pipe 315 to rotate (simultaneously, the copper alloy wire 200 rotates within the inlet pipe 315). The centerline of the rotating ring 314 is colinear with the centerline of the grinding mechanism 32, and the centerline of the inlet pipe 315 deviates from the centerline of the rotating ring 314. This facilitates the inlet pipe 315 to drive the copper alloy wire 200 to perform a circular planetary motion around the centerline of the rotating ring 314, which helps the copper alloy wire 200 always adhere to the grinding mechanism 32, achieves uniform grinding, effectively removes oxide scale on the surface of the copper alloy wire 200, and increases the grinding area and grinding efficiency.

[0078] Optionally, the inner wall of the wire inlet tube 315 on the rotating ring 314 is further provided with bristles for cleaning the copper alloy wire 200. This allows the surface of the copper alloy wire 200 to be pre-cleaned and preliminarily polished before entering the polishing mechanism 32, thereby improving the polishing effect after entering the polishing mechanism 32. Similarly, the copper alloy wire 200 can be cleaned after polishing to reduce the adhesion of dust and other impurities generated during polishing to the copper alloy wire 200. Furthermore, the wire inlet tube 315 rotates along with the rotating ring 314, driving the bristles therein to rotate. The bristles therein clean the copper alloy wire 200, effectively improving the cleaning effect.

[0079] In some embodiments, see Figure 2 and Figure 3 The transmission assembly 313 includes a driving wheel 3131, a driven wheel 3132, a first transmission belt 3133, a first sheave 3134, a second sheave 3135, a first connecting shaft 3136, and a second connecting shaft 3137. The driving wheel 3131 is arranged at the power output end of the driving unit 312. The driven wheel 3132 is rotatably arranged on the support frame 311. The first transmission belt 3133 is connected to the driving wheel 3131 and the driven wheel 3132. The first sheave 3134 is connected to the driving wheel 3131 and is arranged to rotate coaxially with the driving wheel 3131; the second sheave 3135 is connected to the driven wheel 3132 and is arranged to rotate coaxially with the driven wheel 3132. The first sheave 3134 and the second sheave 3135 are both located on the outside of the rotating ring 314 and are respectively connected to the rotating ring 314 in a rolling manner, so as to drive the rotating ring 314 to rotate. The first connecting shaft 3136 connects the driving wheel 3131 and the first sheave 3134 , and the second connecting shaft 3137 connects the driven wheel 3132 and the second sheave 3135 .

[0080] It can be understood that the first sheave 3134 and the second sheave 3135 are components that cooperate with the rotating ring 314 and are used to drive the rotating ring 314 to rotate. The first sheave 3134 and the second sheave 3135 can be various types of structures, such as gears, pulleys, etc., but are not limited to these.

[0081] With this arrangement, the power output end of the drive unit 312 drives the driving wheel 3131 to rotate clockwise. The driving wheel 3131 drives the driven wheel 3132 to rotate clockwise via the first transmission belt 3133. The driving wheel 3131 then drives the first sheave 3134 to rotate clockwise via the first connecting shaft 3136. The driven wheel 3132 drives the second sheave 3135 to rotate clockwise via the second connecting shaft 3137. This facilitates the first and second sheaves 3134, 3135 to drive the rotating ring 314 to rotate counterclockwise, thereby driving the copper alloy wire 200 to rotate counterclockwise and polish during transmission. The belt drive helps maintain the stability of the copper alloy wire 200 during transmission, and the belt drive structure is simple, easy to maintain, and low in cost.

[0082] In some embodiments, see Figure 2 and Figure 3 There are two driving parts 312, two driving wheels 3131 and two driven wheels, and the two driving wheels 3131 are respectively arranged on the power output ends of the two driving parts 312; there are two first sheaves 3134 and two second sheaves 3135, and the two first sheaves 3134 and the two second sheaves 3135 are arranged around the outside of the rotating ring 314.

[0083] There are two first connecting shafts 3136 and two second connecting shafts 3137 , and the driving wheel 3131 , the first connecting shaft 3136 , and the first sheave 3134 are connected in a one-to-one correspondence; the driven wheel 3132 , the second connecting shaft 3137 , and the second sheave 3135 are connected in a one-to-one correspondence.

[0084] With this arrangement, the two driving wheels 3131 respectively drive the two driven wheels 3132 to rotate, allowing the transmission assembly 313 to remain relatively stable during transmission. The two first sheaves 3134 and the two second sheaves 3135 are disposed around the outer periphery of the rotating ring 314, facilitating uniform force distribution on the rotating ring 314 during rotation. This maintains relative stability of the copper alloy wire 200 being transmitted, facilitating uniform polishing of the copper alloy wire 200 by the polishing mechanism 32.

[0085] In some embodiments, see Figure 2 The grinding mechanism 32 includes a support base 321 and a grinding portion 322. The support base 321 is located between the two driving mechanisms 31. The grinding portion 322 is disposed on the support base 321. A grinding through hole 32201 is provided inside the grinding portion 322 for grinding the copper alloy wire 200 input by the rotating ring 314.

[0086] It can be understood that the support seat 321 is a mechanism for supporting the polishing part 322 , and the support seat 321 can be a plate-shaped structure or a block-shaped structure.

[0087] The grinding portion 322 is used to grind the copper alloy wire 200. The grinding portion 322 can be various types of cylindrical grinding structures. The inner wall of the grinding through hole 32201 is the specific grinding part for grinding the copper alloy wire 200. The inner wall of the grinding through hole 32201 can be a rough surface, such as a frosted surface, and its roughness can be set according to the actual needs of grinding, but is not limited to this.

[0088] This arrangement places the centerline of the grinding portion 322 on the same line as the centerline of the rotating ring 314, facilitating the copper alloy wire 200 to pass through the wire inlet tube 315, located on the inner wall of the rotating ring 314, at a suitable angle. This prevents the copper alloy wire 200 from being deflected excessively when entering the wire inlet tube 315 and causing wear, thereby allowing the copper alloy wire 200 to more closely adhere to the inner wall of the grinding portion 322. When the driving mechanism 31 rotates the rotating ring 314, the copper alloy wire 200 rotates around the centerline of the grinding portion 322 along the inner wall of the grinding through-hole 32201. This friction with the inner wall of the grinding through-hole 32201 causes the copper alloy wire 200 to be polished. This ensures that the outer circumferential wall of the copper alloy wire 200 contacts the inner wall of the grinding through-hole 32201 at least once during rotation, facilitating uniform grinding of the copper alloy wire 200 by the grinding portion 322 and more effectively removing oxide scale. Moreover, the contact between the copper alloy wire 200 and the inner wall of the polished through hole 32201 is elastic contact, that is, when a part of the copper alloy wire 200 contacts the inner wall of the polished through hole 32201, the other part does not contact and is not subjected to extrusion force, which is non-extrusion contact. Compared with the method of circumferentially wrapping the copper alloy wire 200 and subjecting it to extrusion contact polishing, it can effectively reduce the occurrence of over-polishing of the copper alloy wire 200.

[0089] Optionally, see Figure 4A cavity is provided on the inner wall of the rotating ring 314, and a plurality of slots 31401 are provided on the inner side wall of the cavity. The wire inlet pipe 315 includes a horizontal pipe 3151, a vertical pipe 3152, a fixed shaft 3153, a connecting piece 3154 and a spring positioning pin 3155. The vertical pipe 3152 is slidably arranged inside the cavity of the rotating ring 314 and is detachably connected to the rotating ring 314. The axis of the horizontal pipe 3151 is perpendicular to the axis of the vertical pipe 3152. The horizontal pipe 3151 is arranged at one end of the vertical pipe 3152 away from the cavity and is used for the copper alloy wire to be passed through. The fixed shaft 3153 is arranged on the inner side wall of the vertical pipe 3152. The connecting piece 3154 is arranged on the fixed shaft 3153. The spring positioning pin 3155 is movably installed in the vertical tube 3152 , and the protrusion of one end of the spring positioning pin 3155 extending to the outside of the vertical tube 3152 is connected to the card slot 31401 , and the other end of the spring positioning pin 3155 is connected to the connecting piece 3154 .

[0090] It is understood that the spring locating pin 3155 is a component for cooperating with the slot 31401. The number of spring locating pins 3155 can be two, and the spring locating pins 3155 can be various types of positioning elements, such as a spring telescopic element, a pneumatic telescopic rod, etc. The connecting member 3154 is an elastic element that can undergo elastic deformation when subjected to force.

[0091] With such a configuration, when it is necessary to grind copper alloy wires 200 with different sizes or different thicknesses of oxide scale, when the wire inlet tube 315 is pulled outward from the rotating ring 314 or pushed inward, the vertical tube 3152 slides and fits into the inner cavity of the rotating ring 314, thereby adjusting the telescopic length of the vertical tube 3152, so that the wire inlet tube 315 can adapt to copper alloy wires of different sizes, thereby facilitating the subsequent grinding mechanism 32 to grind copper alloy wires 200 with different degrees of oxidation.

[0092] When the vertical tube 3152 slides along the inner cavity of the rotating ring 314 under the action of external force, the raised portion of the spring locating pin 3155 continues to contact the card slot 31401, and is squeezed by the card slot 31401 to make the spring locating pin 3155 slide on the vertical tube 3152, so that the two ends of the connecting piece 3154 are compressed, and the spring locating pin 3155 follows the trajectory of the card slot 31401 to slide into the next card slot 31401 (the inner wall of the card slot 31401 and the raised portion of the spring locating pin 3155 are matched through the inclined surface, so that the spring locating pin 3155 can align with the card slot when it is under force The inner wall of the groove 31401 slides relative to each other), the vertical tube 3152 can be pulled outward or pushed inward away from or close to the rotating ring 314, thereby adjusting the telescopic length of the wire inlet tube 315 and making the horizontal tube 3151 close to or away from the center line of the rotating ring 314, so as to adjust the deflection angle of the copper alloy wire 200 entering the wire inlet tube 315, and further adjust the interaction force between the copper alloy wire 200 and the inner wall of the grinding through hole 32201, so as to facilitate the wire inlet tube 315 to drive the copper alloy wires 200 of various sizes to fit in the grinding mechanism 32 and rotate, so that the copper alloy wire 200 is evenly ground during grinding.

[0093] For example, see Figure 5 The polishing mechanism 32 also includes two bearing seats 323, two rolling bearings 324, a motor 325, a pulley 326, and a second transmission belt 327. One bearing seat 323 is located at the input end of the polishing unit 322, and the other bearing seat 323 is located at the output end of the polishing unit 322. The polishing unit 322 is rotatably mounted on the two bearing seats 323 via two rolling bearings 324. The motor 325 is located on one side of the polishing unit 322; the pulley 326 is located at the power output end of the motor 325. The second transmission belt 327 connects the pulley 326 and the polishing unit 322.

[0094] With this arrangement, the power output end of the motor 325 drives the pulley 326 to rotate clockwise, thereby driving the polishing unit 322 to rotate clockwise via the second transmission belt 327. During this rotation, the polishing unit 322 drives the inner ring of the rolling bearing 324 to rotate. The two bearing seats 323 support the rotation of the polishing unit 322 via the rolling bearing 324, facilitating the polishing unit 322 to rotate and polish the copper alloy wire 200. Furthermore, when the polishing unit 322 rotates clockwise, the rotating ring 314 drives the copper alloy wire 200 to rotate counterclockwise, with the two rotating in opposite directions. This effectively improves the polishing effect and efficiency of the polishing unit 322 on the copper alloy wire 200, allowing the polishing unit 322 to polish the surface of the copper alloy wire 200 evenly and comprehensively, thereby achieving better oxide scale removal.

[0095] In some embodiments, see Figures 1 to 4An air inlet 32202 is provided at the top of the grinding part 322; the copper alloy wire production line also includes an air blowing mechanism 50, which is located on one side of the grinding mechanism 32, and the air outlet nozzle of the air blowing mechanism 50 is connected to the air inlet 32202, which is used to clean the debris dropped after the grinding part 322 grinds the copper alloy wire 200.

[0096] It can be understood that the blowing mechanism 50 is a mechanism that can provide airflow, for example, it can include an air pump or an air cylinder, etc., but is not limited thereto.

[0097] With such arrangement, when the copper alloy wire 200 is polished in the polishing mechanism 32, the oxide scale debris after polishing falls on the bottom of the polishing part 322, and the air outlet nozzle of the blowing mechanism 50 blows air into the interior of the polishing part 322 through the air inlet hole 32202 at the top of the polishing part 322, which can clean up the debris and prevent the debris from adhering to the inner wall surface of the polishing through hole 32201 and affecting the contact between the inner wall of the polishing through hole 32201 and the copper alloy wire 200, thereby improving the polishing effect.

[0098] Optionally, the copper alloy wire production line 100 may further include a heating device, and the blowing mechanism 50 is connected to the heating device. The heating device is used to heat the airflow output by the blowing mechanism 50, so that the gas output by the blowing mechanism 50 is hot air and is sent into the air inlet 32202. When the hot air contacts the copper alloy wire 200, its surface temperature can be increased, which is beneficial to softening the oxide scale, so that the polishing mechanism 32 can perform polishing better, effectively improving the polishing effect.

[0099] In some embodiments, see Figures 1 to 4 There are two air inlet holes 32202, and the air outlet directions of the two air inlet holes 32202 intersect; the air inlet end of one of the air inlet holes 32202 is inclined toward one of the driving mechanisms 31, and the air outlet end is inclined downward away from one of the driving mechanisms 31; the air inlet end of the other air inlet hole 32202 is inclined toward the other driving mechanism 31, and the air outlet end is inclined downward away from the other driving mechanism 31.

[0100] With this arrangement, two relatively inclined air inlet holes 32202 are opened on the top of the grinding part 322, which is conducive to the blowing mechanism 50 blowing off the oxide scale debris after grinding from the left and right sides of the grinding part 322, preventing the debris from scattering on the inner wall of the grinding part 322 and affecting the grinding effect.

[0101] In some embodiments, see Figures 1 to 4The cleaning mechanism 40 includes a cleaning tank 41 and a guide wheel assembly 42. The cleaning tank 41 is located at the output side of the other driving mechanism 31 and is used to clean the copper alloy wire 200 output by the other driving mechanism 31. The guide wheel assembly 42 is set on the cleaning tank 41 and is used to transport the copper alloy wire 200 output by the other driving mechanism 31. 。

[0102] Optionally, the wire guide mechanism 20 further includes a wire outlet adjustment assembly 23, which is located on the output side of another drive mechanism 31 and is used to adjust the tension of the copper alloy wire 200 between the other drive mechanism 31 and the guide wheel assembly 42, and is also used to keep the polished copper alloy wire 200 collinear with the center line of the other drive mechanism 31.

[0103] With this arrangement, after the copper alloy wire 200 is polished within the polishing mechanism 32, debris or impurities from the oxide scale may adhere to its surface. The copper alloy wire 200 with these debris or impurities is then delivered to the cleaning mechanism 40 by the other drive mechanism 31. The guide wheel assembly 42 then conveys the copper alloy wire 200 to the cleaning tank 41 for cleaning. The polished copper alloy wire 200 is then driven by the other drive mechanism 31 to perform a planetary orbital motion around the centerline of the polishing mechanism 32. Because this rotation generates tensile stress, the wire outlet adjustment assembly 23 is used to adjust the copper alloy wire 200 output from the other drive mechanism 31, facilitating the transfer of the copper alloy wire 200 to the cleaning mechanism 40 by the guide wheel assembly 42.

[0104] See also Figure 1 The present application also provides a method for producing a copper alloy wire, using the copper alloy wire production line 100 of any of the above embodiments. The method includes:

[0105] The pay-off stand 10 pays out the copper alloy wire 200 to the lead wire mechanism 20 .

[0106] The wire guide mechanism 20 outputs the copper alloy wire 200 to one of the driving mechanisms 31 of the peeling component 30, and the driving mechanism 31 drives the copper alloy wire 200 to rotate circumferentially around the center line of the grinding mechanism 32 of the peeling component 30, so that the grinding mechanism 32 grinds the copper alloy wire 200 during the circumferential rotation of the copper alloy wire 200.

[0107] The cleaning mechanism 40 cleans the peeled copper alloy wire 200 output from the other driving mechanism 31 of the peeling assembly 30 .

[0108] From the above, it can be seen that in the copper alloy wire production method provided in the embodiment of the present application, the wire mechanism 20 can adjust the tension of the copper alloy wire 200 between the wire pay-off frame 10 and the drive mechanism 31, so that the force on the copper alloy wire 200 is more uniform, which is beneficial for one of the drive mechanisms 31 to drive the copper alloy wire 200 to perform circumferential rotation around the center line of the polishing mechanism 32, thereby peeling the oxide scale generated on the surface of the copper alloy wire 200 through the peeling component 30, and the other drive mechanism 31 transfers the copper alloy wire 200 polished by the polishing mechanism 32 to the cleaning mechanism 40 for cleaning, which can improve the surface quality of the copper alloy wire 200 and improve the conductivity and connection performance of the copper alloy wire 200.

[0109] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
