[0026] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0027] like Figures 1 to 5 As shown, a copper wire annealing device according to an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , including an annealing box 8, a constant speed wheel 2 is arranged on one side of the front of the annealing box 8, a conductive wheel 3 is arranged on the other side of the front of the annealing box 8, a motor group 5 is installed on the other side of the annealing box 8, a copper wire body 700 is arranged on the outer side of the conductive wheel 3, a cooling water gun 1 for cooling the copper wire body 700 is installed on the front of the annealing box 8, the motor group 5 heats the conductive wheel 3, and then heats the copper wire body 700 through the conductive wheel 3, and a cleaning component 4 for cleaning the copper wire body 700 is connected to the other side of the front of the annealing box 8, and the cleaning component 4 includes a vibration reduction component 402 for vibration reduction.

[0028] Specifically, the copper wire body 700 first passes into the inner side of the cleaning component 4 from the other side of the annealing box 8, and the cleaning component 4 cleans and reduces vibration of the copper wire body 700. After passing through the cleaning component 4, the copper wire body 700 is wound around the outside of the conductive wheel 3 and the constant speed wheel 2, and finally the copper wire body 700 is discharged from one side of the annealing box 8. The copper wire body 700 is heated by the conductive wheel 3, and the constant speed wheel 2 drives the copper wire body 700 to be transported as a whole. Before being transported to the constant speed wheel 2, the copper wire body 700 is cooled by the cooling water gun 1.

[0029] Please refer to Figure 3 , Figure 4 , Figure 5The cleaning component 4 also includes a limit seat 403, a mounting rod is provided on the back of the limit seat 403, the back of the mounting rod of the limit seat 403 is fixedly connected to the annealing box 8, and fixed grooves are evenly spaced on the circumference of both sides of the limit seat 403. The vibration reduction component 402 is located on the inner side of the fixed groove of the limit seat 403, and the vibration reduction component 402 is connected to the cleaning wheel component 404 near the center of the limit seat 403.

[0030] Please refer to Figure 5 , characterized in that the vibration reduction assembly 402 includes an inner movable rod 4023, an outer sleeve 4021 is movably provided on the outer side of the inner movable rod 4023, a spring 4022 is fixedly connected to the top of the inner movable rod 4023, and one end of the spring 4022 away from the inner movable rod 4023 is fixedly connected to the inner wall of the outer sleeve 4021.

[0031] Specifically, the limiting seat 403 is fixedly connected to the annealing box 8 to ensure the positioning of the vibration reduction assembly 402, and the copper wire body 700 passes through the plurality of cleaning wheel assemblies 404. Figure 5 As shown, the bottom of the inner movable rod 4023 is toward the center of the limiting seat 403. When the copper wire body 700 in contact with the cleaning wheel assembly 404 shakes, it will push the cleaning wheel assembly 404 and thus push the inner movable rod 4023 to move in the outer sleeve 4021. Since the inner movable rod 4023 is limited by the outer outer sleeve 4021, the inner movable rod 4023 moves in a direction close to the spring 4022 and parallel to the outer sleeve 4021, thereby squeezing the spring 4022, and rebounding under the action of the elastic force of the spring 4022 itself, so that the cleaning wheel assembly 404 is reset to offset the shaking of the copper wire body 700, thereby avoiding local ignition of the copper wire body 700 due to shaking.

[0032] Please refer to Figure 5 The cleaning wheel assembly 404 includes a base 4041, a circular shaft is arranged on the inner side of the base 4041, a cleaning wheel body 4042 is rotatably connected to the outer side of the circumference of the base 4041, the outer side of the cleaning wheel body 4042 is in contact with the outer side of the copper wire body 700, and the side of the base 4041 away from the center of the limiting seat 403 is fixedly connected to the bottom of the inner movable rod 4023.

[0033] Specifically, the cleaning wheel body 4042 fits the outer side of the copper wire body 700, making it easier to scrape off the copper powder on the surface of the copper wire body 700, and when the copper wire body 700 vibrates slightly, the cleaning wheel body 4042 will be subjected to the thrust generated by the vibration of the copper wire body 700, thereby pushing the inner movable rod 4023. When the conductive wheel 3 transmits the copper wire body 700 through the cleaning wheel assembly 404, the cleaning wheel body 4042 will rotate, reducing the conduction resistance and avoiding frictional overheating.

[0034] Please refer to Figure 3 , Figure 4 , Figure 5 An adjusting component 401 is arranged on the outer side of the limit seat 403, and the adjusting component 401 includes a driven gear 4011 and a driving gear 4012. The outer teeth of the driven gear 4011 and the driving gear 4012 are meshed with each other. The driven gear 4011 is rotatably connected to the outer side of the limit seat 403. Arc-shaped limit holes 4014 are opened around one side of the driven gear 4011. The other side of the driving gear 4012 is fixedly connected to a driving motor 4013. The back side of the outer sleeve 4021 is fixedly connected to a limit rod 4024, and the limit rod 4024 is clamped on the inner side of the arc-shaped limit hole 4014.

[0035] Please refer to Figure 3 , Figure 4 , Figure 5 The length of the limit rod 4024 matches the thickness tolerance of the driven gear 4011, the outer diameter of the limit rod 4024 matches the width clearance of the arc-shaped limit hole 4014, the mounting rods of the limit seat 403 are respectively fixedly connected to the two sides of the back side of the limit seat 403, and the distance between the two mounting rods of the limit seat 403 matches the thickness clearance of the driven gear 4011.

[0036] Specifically, before annealing the copper wire body 700, the adjustment assembly 401 is adjusted according to the diameter of the copper wire body 700 to adjust the distance between the cleaning wheel assemblies 404, and the driving motor 4013 is started to drive the driving gear 4012 to rotate clockwise. Since the driving gear 4012 and the driving motor 4013 are engaged, the driven gear 4011 is driven to rotate counterclockwise. When the driven gear 4011 rotates, the position of the arc-shaped limiting hole 4014 also changes. Since the outer sleeve 4021 is limited by the fixed groove of the limiting seat 403, and the limiting rod 4024 is It is clamped in the arc-shaped limiting hole 4014. When the arc-shaped limiting hole 4014 rotates counterclockwise, under the limitation of the arc-shaped limiting hole 4014 and the fixing groove of the limiting seat 403, the vibration reduction assembly 402 spreads along the fixing groove of the limiting seat 403 in the direction away from the center of the limiting seat 403, thereby expanding the distance between the cleaning wheel assemblies 404 to adapt to the copper wire body 700 with a larger diameter. Conversely, starting the driving motor 4013 to drive the driving gear 4012 to rotate counterclockwise reduces the distance between the cleaning wheel assemblies 404 to adapt to the copper wire body 700 with a small diameter.

[0037] Please refer to Figure 2 , Figure 3 A scraping assembly 6 is also provided on the front of the annealing box 8. The scraping assembly 6 includes a mounting seat 602. A scraper 601 is rotatably connected to the outer side of the mounting seat 602. The other side of the scraper 601 is tightly fitted with one side of the limiting seat 403. A friction ring is provided at the connection between the scraper 601 and the mounting seat 602.

[0038] Specifically, after the entire roll of copper wire main body 700 completely passes through the cleaning component 4, as the copper wire main body 700 passes through the cleaning wheel assembly 404, part of the copper powder will be scraped off by the cleaning wheel main body 4042 and fall from one side of the limiting seat 403, but some copper powder will remain adsorbed on one side of the limiting seat 403. Before the next new roll is annealed, this residual copper powder will be contaminated by water vapor and dust in the environment, affecting the purity of the next new roll of copper wire main body 700. Therefore, after the entire roll of copper wire main body 700 completely passes, the operator moves the scraper 601 to scrape one side of the limiting seat 403 to scrape off the residual copper powder and then moves it upward to restore it to the state as shown in the figure. Figure 3 As shown, a friction ring is provided at the connection between the scraper 601 and the mounting seat 602 . When no external force is involved, the angle of the scraper 601 will not change, and will not affect the normal passage of the copper wire body 700 through the cleaning component 4 .

[0039] Please refer to Figure 1 A square groove is provided at the bottom of the annealing box 8, and bevels are provided around the square groove of the annealing box 8.

[0040] Specifically, in the process of the cleaning component 4 eliminating the shaking of the copper wire body 700, the copper wire body 700 will generate copper powder, and some of the copper powder will fall into the square groove of the annealing box 8. The bevel can help the copper powder slide into the square groove, and the copper powder that falls due to the shaking during the transmission process is collected for secondary utilization, and the water cooled by the cooling water gun 1 is also collected in the square groove of the annealing box 8.

[0041] How it works Before annealing the copper wire body 700, the adjustment assembly 401 is adjusted according to the diameter of the copper wire body 700 to adjust the distance between the cleaning wheel assemblies 404, and the driving motor 4013 is started to drive the driving gear 4012 to rotate clockwise. Since the driving gear 4012 and the driving motor 4013 are engaged, the driven gear 4011 is driven to rotate counterclockwise. When the driven gear 4011 rotates, the position of the arc-shaped limiting hole 4014 also changes. Since the outer sleeve 4021 is limited by the fixed groove of the limiting seat 403, and the limiting rod 4024 is clamped In the arc-shaped limiting hole 4014, when the arc-shaped limiting hole 4014 rotates counterclockwise, under the limitation of the arc-shaped limiting hole 4014 and the fixing groove of the limiting seat 403, the vibration reduction assembly 402 spreads along the fixing groove of the limiting seat 403 in the direction away from the center of the limiting seat 403, thereby expanding the distance between the cleaning wheel assemblies 404 to adapt to the copper wire body 700 with a larger diameter. On the contrary, starting the driving motor 4013 to drive the driving gear 4012 to rotate counterclockwise reduces the distance between the cleaning wheel assemblies 404 to adapt to the copper wire body 700 with a small diameter. After adjustment, if Figure 2As shown, the copper wire body 700 first passes through the inner side of the cleaning assembly 4 from the other side of the annealing box 8, and after passing through the cleaning assembly 4, the copper wire body 700 is wound around the outer side of the conductive wheel 3 and the constant speed wheel 2, and finally the copper wire body 700 is discharged from one side of the annealing box 8. The copper wire body 700 is heated by the conductive wheel 3, and the constant speed wheel 2 drives the copper wire body 700 to be transported as a whole, and before being transported to the constant speed wheel 2, the copper wire body 700 is cooled by the cooling water gun 1. When the copper wire body 700 passes through the cleaning assembly 4, if the copper wire body 700 shakes slightly The cleaning wheel body 4042 will be subjected to the thrust generated by the shaking of the copper wire body 700, pushing the cleaning wheel assembly 404 and thus pushing the inner movable rod 4023 to move in the outer sleeve 4021. Since the inner movable rod 4023 is limited by the outer sleeve 4021, the inner movable rod 4023 moves in a direction close to the spring 4022 and parallel to the outer sleeve 4021, thereby squeezing the spring 4022, and rebounding under the action of the elastic force of the spring 4022 itself, so that the cleaning wheel assembly 404 is reset to offset the shaking of the copper wire body 700. After the entire copper wire body 700 has completely passed through the cleaning assembly 4, the operator moves the scraper 601 to scrape one side of the limit seat 403 to scrape off the remaining copper powder and then moves it upward to restore it to the state as shown in the figure. Figure 3 As shown, a friction ring is provided at the connection between the scraper 601 and the mounting seat 602 . When no external force is involved, the angle of the scraper 601 will not change, and will not affect the normal passage of the copper wire body 700 through the cleaning component 4 .

[0042] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
