Description

Technical Field

[0001] This utility model relates to the field of copper wire processing technology, and in particular to a device for removing oxides from the outer surface of bare copper wire. Background Technology

[0002] Currently, in the bare copper wire processing production process, the surface of the copper wire is prone to oxidation reaction due to contact with air, forming an oxide layer. This oxide layer will significantly affect the conductivity of the copper wire, the welding quality and the adhesion of subsequent plating layers. Therefore, it is necessary to thoroughly remove the oxide layer.

[0003] Among them, the mainstream oxide removal method in the industry is the dilute hydrochloric acid immersion method, which achieves oxide layer stripping through the chemical reaction between dilute hydrochloric acid and the oxide layer. Although this method has the advantages of high reaction efficiency and low cost, the following key technical problems still exist in practical applications.

[0004] In the existing processing flow, after copper wire is soaked in a dilute hydrochloric acid bath, it needs to be transferred to the cleaning station by a separate conveying device (such as a traction roller or conveyor belt). The conveying device and the cleaning device belong to two independent systems. This not only requires additional drive equipment (such as motors and air pumps), which increases the overall energy consumption of the equipment and makes the structure more complex, but also easily causes problems due to the mismatch between the conveying speed and the cleaning rhythm: when the conveying speed is too fast, the cleaning device cannot fully act on the surface of the copper wire, resulting in incomplete removal of residual chemicals and oxides; when the conveying speed is too slow, the copper wire will accumulate at the cleaning station, affecting production efficiency.

[0005] To address this issue, we propose a device for removing oxides from the outer surface of bare copper wire processing. Utility Model Content

[0006] The purpose of this invention is to solve the problems existing in the prior art by proposing a device for removing oxides from the outer surface of bare copper wire processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A device for removing oxides from the outer surface of bare copper wire processing includes: a base, on which a material roller is rotatably mounted, copper wire being wound around the outer surface of the material roller, and a cleaning box being threaded through one end of the copper wire; a toothed ring is installed at the bottom of the material roller, and a gear is meshed on the toothed ring; a swinging air outlet mechanism is mounted on the gear, and a compressed air cylinder is configured inside the swinging air outlet mechanism; both ends of the compressed air cylinder are respectively connected to the cleaning box through conduits to form a closed air pressure delivery path, and continuously deliver air pressure to the cleaning box, thereby efficiently removing dilute hydrochloric acid and oxides adhering to the surface of the copper wire by means of airflow.

[0008] Preferably, a through groove is formed in the middle of the cleaning box, through which copper wires can move; a cavity is formed inside the cleaning box, and a number of nozzles are assembled on one side of the cavity, each nozzle is connected to the cavity, and the air jet direction of all the nozzles is set towards the central axis of the cleaning box.

[0009] Preferably, the swinging air outlet mechanism includes a linkage arm rotatably mounted on the outside of the gear, and a squeezing rod rotatably mounted on the other end of the linkage arm via a rotating shaft. The other end of the squeezing rod movably passes through the air compressor and is fixedly mounted with a sealing plug. The sealing plug is movably connected to the inner cavity of the air compressor, and conduits are installed at both opposite ends of the air compressor.

[0010] Preferably, the air compressor has air outlets installed on both opposite sides, and air inlets are installed near the ends of the two air outlets. All air outlets and air inlets are connected to the inner cavity of the air compressor, and one-way valves are installed in both the air outlets and air inlets.

[0011] Preferably, a clamp is fixedly installed on the outside of the air compressor, and the clamp is fixedly installed on the base.

[0012] Preferably, one side of the extrusion rod is cylindrical, and a support ring is slidably mounted on the extrusion rod, with the support ring fixedly mounted on the base.

[0013] Preferably, a support rod is fixedly installed on the base, and a slip ring is slidably installed on the support rod, with the side wall of the slip ring fixedly connected to the cleaning box.

[0014] Preferably, the top and bottom of the support rod are fixedly installed with blocks, and the horizontal height of the two blocks corresponds to the top and bottom of the material roller.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention enables the orderly collection and transport of copper wire by winding copper wire onto the outer surface of the roller, providing a stable transport foundation for subsequent processing of the copper wire after it has been soaked in a dilute hydrochloric acid bath to remove oxides. Through the meshing transmission of the toothed ring and gear at the bottom of the roller, the air compressor of the oscillating air outlet mechanism can be driven synchronously, eliminating the need for an additional drive source and achieving a linkage and energy-saving effect between copper wire transport and air pressure generation. The air compressor continuously delivers air pressure to the cleaning box through a conduit, effectively removing residual chemicals and incompletely removed oxides from the copper wire surface caused by dilute hydrochloric acid soaking, preventing secondary corrosion of the copper wire by residual dilute hydrochloric acid. Furthermore, the airflow cleaning method is more efficient and non-damaging than traditional wiping, effectively ensuring the cleanliness and flatness of the bare copper wire's outer surface.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-4 A device for removing oxides from the outer surface of bare copper wire processing includes: a base 1, a material roller 11 rotatably mounted on the base 1, copper wire being wound on the outer surface of the material roller 11, and a cleaning box 12 being threaded through one end of the copper wire; A toothed ring 2 is installed at the bottom of the material roller 11. A gear 21 is meshed with the toothed ring 2. A swinging air outlet mechanism is mounted on the gear 21. An air compressor 25 is configured inside the swinging air outlet mechanism. The two ends of the air compressor 25 are connected to the cleaning box 12 through the conduit 28 to form a closed air pressure delivery channel and continuously deliver air pressure to the cleaning box 12. With the help of airflow, the dilute hydrochloric acid and oxides attached to the surface of the copper wire can be efficiently removed.

[0020] When the equipment is working, the base 1 provides support for the overall structure, and the material roller 11 rotates on the base 1. The copper wire wrapped on its outer surface is conveyed in an orderly manner as the material roller 11 rotates. This conveying process needs to be connected to the previous process of soaking the copper wire in a dilute hydrochloric acid pool to remove oxides. That is, the copper wire soaked in dilute hydrochloric acid is conveyed to the material roller 11 and wrapped. The stable rotation of the material roller 11 provides a continuous and uniform copper wire conveying foundation for the subsequent cleaning process.

[0021] Simultaneously, the toothed ring 2 fixed at the bottom of the material roller 11 rotates synchronously with the material roller 11. Because the toothed ring 2 meshes with the gear 21, the rotational power of the toothed ring 2 is transmitted to the gear 21, causing the gear 21 to rotate. The gear 21 further drives the swing air outlet mechanism assembled with it to operate, so that the air compressor 25 generates air pressure. The air compressor 25 is connected to the cleaning box 12 through the two end guide tubes 28 to form a closed air pressure passage. The air pressure generated by the air compressor 25 is continuously transported to the cleaning box 12 along the guide tubes 28. When one end of the copper wire soaked in dilute hydrochloric acid is connected to the cleaning box 12, the airflow in the cleaning box 12 directly acts on the surface of the copper wire, washing away the residual dilute hydrochloric acid solution and the oxides that have not been completely removed, and finally realizing the integrated operation of copper wire transportation and cleaning.

[0022] Furthermore, a through groove 3 is provided through the middle of the cleaning box 12, through the groove 3 for copper wires to pass through; a cavity 31 is formed inside the cleaning box 12, and a number of nozzles 32 are assembled on one side of it. Each nozzle 32 is connected to the cavity 31, and the air jet direction of all nozzles 32 is set towards the central axis of the cleaning box 12.

[0023] After being soaked in dilute hydrochloric acid, the copper wire is moved along the through groove 3 in the middle of the cleaning box 12. The inner wall of the through groove 3 and the outer periphery of the copper wire form a gap fit, which not only ensures the smooth transport of the copper wire, but also limits the deviation of the copper wire during the transport process through the radial constraint of the through groove 3, ensuring that the copper wire is always within the processing range of the cleaning box 12.

[0024] Meanwhile, the cavity 31 inside the cleaning box 12 serves as a temporary air pressure storage space, and the air pressure delivered by the air compressor 25 through the conduit 28; since several nozzles 32 mounted on one side of the cleaning box 12 are all connected to the cavity 31, the air pressure in the cavity 31 will be evenly distributed to each nozzle 32, and the jet direction of all nozzles 32 is towards the central axis of the cleaning box 12, so that the airflow is ejected from the circumference of the copper wire at multiple angles, forming an annular airflow wrapping area around the copper wire; when the copper wire passes through the through groove 3, the annular airflow directly acts on the surface of the copper wire, fully covering the area of ​​dilute hydrochloric acid residue and oxide adhesion, and the impurities are peeled off the surface of the copper wire by the impact force of the airflow, achieving uniform and thorough cleaning.

[0025] Furthermore, the swing air outlet mechanism includes a linkage arm 22 rotatably mounted on the outside of the gear 21, a bearing fixedly mounted on the outside of the gear 21, a rotating shaft fixedly connected to the inner shaft of the bearing, the other end of the rotating shaft fixedly connected to the linkage arm 22, a squeezing rod 23 rotatably mounted on the other end of the linkage arm 22 via the rotating shaft, the other end of the squeezing rod 23 movably passing through the air compressor 25 and fixedly mounted with a sealing plug 24, and the squeezing rod 23 movably seals with the air compressor 25 through a sealing ring, the sealing plug 24 movably connects with the inner cavity of the air compressor 25, a sealing ring is sleeved on the outside of the sealing plug 24, the sealing ring fits against the inner wall of the air compressor 25, and conduits 28 are installed at both opposite ends of the air compressor 25.

[0026] When gear 21 rotates with gear ring 2, the linkage arm 22 rotatably mounted on its outer side is driven by gear 21 to oscillate periodically. The other end of linkage arm 22 is rotatably connected to extrusion rod 23 via a rotating shaft. The oscillation of linkage arm 22 is converted into reciprocating linear motion of extrusion rod 23. Because the sealing plug 24 fixedly mounted on the other end of extrusion rod 23 is movably connected to the inner cavity of air compressor 25, the reciprocating motion of extrusion rod 23 drives sealing plug 24 to slide synchronously back and forth in the inner cavity of air compressor 25. When sealing plug 24 moves towards air compressor 25... 5 When one end moves, the volume of the corresponding area inside the air cylinder 25 decreases and the air pressure increases; when the sealing plug 24 moves to the other end, the volume of the corresponding area inside the air cylinder 25 increases and the air pressure decreases. This reciprocating motion continuously generates air pressure. The entire process does not require an external air pump and is achieved directly by relying on the power of the material roller 11 to transport the copper wire. Moreover, the rhythm of air pressure generation is synchronized with the speed of the material roller 11 transporting the copper wire, ensuring that when the copper wire is transported to the cleaning box 12 after being soaked in dilute hydrochloric acid, the air cylinder 25 can provide air pressure in real time for cleaning.

[0027] Furthermore, air outlets 26 are connected to both sides of the air compressor 25, and air inlets 27 are installed near the ends of the two air outlets 26. All air outlets 26 and air inlets 27 are connected to the inner cavity of the air compressor 25. One-way valves are installed in both the air outlets 26 and the air inlets 27. The one-way valve in the air inlet 27 directs the air to the outside of the air compressor 25, and the one-way valve in the air outlet 26 directs the air to the cleaning box 12.

[0028] When the sealing plug 24 moves toward one end of the compressor cylinder 25, the volume of the area in the compressor cylinder 25 away from the sealing plug 24 increases and a negative pressure is formed. The one-way valve of the air inlet 27 corresponding to this area opens under the action of negative pressure, and the one-way valve of the air outlet 26 closes due to the air pressure difference. Outside air enters the inner cavity of the compressor cylinder 25 along the air inlet 27 to complete the gas replenishment.

[0029] Conversely, when the sealing plug 24 moves in the opposite direction, the gas inside the compressor cylinder 25 is compressed and the air pressure increases. The one-way valve at the outlet 26 opens under positive pressure, and the one-way valve at the inlet 27 closes due to the reverse air pressure difference. The high-pressure gas in the compressor cylinder 25 enters the conduit 28 along the outlet 26 and is then transported to the cavity 31 of the cleaning box 12 through the conduit 28.

[0030] Furthermore, a clamp is fixedly installed on the outside of the air compressor 25, and the clamp is fixedly installed on the base 1.

[0031] Friction between the sealing plug 24 and the inner wall of the compressor cylinder 25, as well as changes in air pressure, can cause the compressor cylinder 25 to vibrate or shift. By using a clamp to hold the outer side of the compressor cylinder 25, the compressor cylinder 25 is rigidly connected to the base 1, limiting the displacement and shaking of the compressor cylinder 25. This fixes the position of the compressor cylinder 25, ensuring that the inner cavity axis remains stable and that the sealing plug 24 reciprocates along the axial direction. This prevents the sealing plug 24 from misaligning and rubbing against the inner wall of the cavity due to displacement of the compressor cylinder 25, or from failing to seal due to tilting of the sealing plug 24.

[0032] Furthermore, one side of the extrusion rod 23 is cylindrical, and a support ring is slidably mounted on the extrusion rod 23, with the support ring fixedly mounted on the base 1.

[0033] When gear 21 drives linkage arm 22 to swing, thereby driving extrusion rod 23 to perform reciprocating linear motion, one side of extrusion rod 23 slides through the support ring. The support ring forms a radial constraint on extrusion rod 23 through its inner hole, restricting extrusion rod 23 from shifting to both sides during reciprocating motion. This ensures that extrusion rod 23 always moves along the axial direction of the inner cavity of air cylinder 25, preventing extrusion rod 23 from causing sealing plug 24 to tilt. This also prevents excessive friction between sealing plug 24 and the inner wall of air cylinder 25, extending the service life of sealing plug 24.

[0034] Furthermore, a support rod 33 is fixedly installed on the base 1, and a slip ring 34 is slidably installed on the support rod 33. The side wall of the slip ring 34 is fixedly connected to the cleaning box 12.

[0035] During the conveying process, the copper wire soaked in dilute hydrochloric acid may experience slight deviations in its radial position due to changes in its own state after soaking or an increase or decrease in the number of copper wire layers on the roller 11. At this time, since the cleaning box 12 is slidably connected to the support rod 33 through the slip ring 34, the operator can push the cleaning box 12 to drive the slip ring 34 to slide synchronously along the support rod 33, thereby adjusting the height position of the cleaning box 12.

[0036] When the copper wire moves upward, the slip ring 34 causes the cleaning box 12 to slide upward along the support rod 33; when the copper wire moves downward, the slip ring 34 causes the cleaning box 12 to slide downward along the support rod 33.

[0037] Furthermore, the top and bottom of the support rod 33 are fixedly installed with stop blocks 35, and the horizontal height of the two stop blocks 35 corresponds to the top and bottom of the material roller 11.

[0038] When the slip ring 34 drives the cleaning box 12 to slide along the support rod 33 to adjust its position, the fixed blocks 35 at the top and bottom of the support rod 33 will physically block the sliding stroke of the slip ring 34. When the slip ring 34 drives the cleaning box 12 to slide up to near the top of the material roller 11, the block 35 at the top of the support rod 33 contacts the upper surface of the slip ring 34, limiting the slip ring 34 from continuing to slide up and preventing the cleaning box 12 from moving up beyond the winding range of the copper wire at the top of the material roller 11. When the slip ring 34 drives the cleaning box 12 down to near the bottom of the material roller 11, the block 35 at the bottom of the support rod 33 contacts the lower surface of the slip ring 34, limiting the slip ring 34 from continuing to slide down and preventing the cleaning box 12 from moving down beyond the winding range of the copper wire at the bottom of the material roller 11.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
