Description

Technical Field

[0001] The present invention relates to the technical field of copper wire processing, and specifically refers to a copper wire tin plating processing device. Background Art

[0002] Tinned copper wire refers to copper wire with a layer of metallic tin plated on its surface. Its material is relatively soft, and its electrical conductivity is good. Compared with bare copper wire, its corrosion resistance and oxidation resistance are stronger, which can greatly extend the service life of weak current cables. Existing copper wire tin plating processing devices generally include a tin plating furnace and a guide roller group for guiding the conveying direction of the copper wire. During the conveying process of the copper wire under the guidance of the guide roller group, the copper wire is conveyed through the tin plating furnace, so that the copper wire contacts the heated and molten liquid tin, thereby evenly plating a layer of tin on the surface of the copper wire.

[0003] Since the molten liquid tin has a relatively high temperature, the tin plating process will cause a large temperature rise of the copper wire, and then cause a significant increase in its elongation. Therefore, when the copper wire is pulled out of the tin plating furnace, a large amount of deformation will occur, which easily affects the quality of the copper wire.

[0004] Therefore, the research purpose of the present invention is to design a copper wire tin plating processing device that can effectively and quickly cool the copper wire output from the tin plating furnace, so as to significantly reduce the problem of the increase in elongation caused by the temperature rise of the tinned copper wire, thereby effectively improving the quality of the tinned copper wire.

[0019] Advantages of the present invention:

[0020] 1) On the basis of the existing tin plating furnace, the present invention is additionally provided with a copper wire cooling mechanism, which includes an air inlet groove arranged on the upper side of the molten tin cavity. A cooling water circulation pipe is fixedly arranged downward in the middle of the air inlet groove. The cooling water circulation pipe is arranged in a wavy shape, and its top is fixedly connected to the top surface of the air inlet groove. Then, a cover is hermetically installed at the opening of the air inlet groove. By cooperating the relief groove provided on the cover with the cooling water circulation pipe, the bottom of the cooling water circulation pipe is extended to the outside of the cover. Finally, U-shaped guide air plates are respectively connected outward between the two sides of the relief groove, and the cross sections of the guide air plates respectively cover the outside of the corresponding cooling water circulation pipes in an arc shape. During use, the air inlet end of the air inlet groove is connected to an external fan, and the cooling water circulation pipe is connected to an external water source. During the tin plating process, the copper wire enters the molten tin cavity through the copper wire inlet roller, passes through the bottom side of the abutting roller, and then respectively passes through the hollow positions of the guide air plates and is output outward along the copper wire outlet roller. When the copper wire passes through the hollow positions of the guide air plates, the flowing air is concentrated and blown towards the hollow positions of the guide air plates under the guidance of each relief groove and the U-shaped guide air plates, so as to quickly and evenly cool the copper wire just after tin plating, significantly reducing the problem of increased elongation rate of the tin-plated copper wire caused by temperature rise, and thus effectively improving the quality of the tin-plated copper wire.

[0021] 2) The flowing air is mainly concentrated and blown towards the hollow positions of the guide air plates, so it can prevent the influence on the copper wire tin plating operation caused by the addition of the copper wire cooling mechanism; moreover, the flowing gas will pass through the wavy cooling water circulation pipe in advance before blowing towards the hollow positions of the guide air plates, so as to reduce the temperature of the gas blown towards the copper wire, further significantly improving the cooling effect on the copper wire just after tin plating.

[0022] 3) The present invention further includes a tin ash removal mechanism, which comprises a bracket. On the bracket, a first ash removal roller, a second ash removal roller, and a third ash removal roller sleeved with a buffer wiping cloth layer are rotatably arranged at intervals. The first ash removal roller and the third ash removal roller are respectively installed on the bracket in a liftable manner through a first N-shaped member, and the second ash removal roller is installed on the bracket in a liftable manner through a second N-shaped member and a connecting rod member equipped with an ultrasonic transducer. After the tin-plated copper wire is completed, it is wound around the top side of the first ash removal roller, the bottom side of the second ash removal roller, and the top side of the third ash removal roller in sequence and then output outward. In this process, under the action of the ultrasonic transducer, the second ash removal roller can perform ultrasonic vibration on the tin-plated copper wire after tin plating, so as to remove the tin ash attached to the surface of the tin-plated copper wire and separate the highly viscous tin ash from the tin-plated copper wire, enabling it to be wiped off by the buffer wiping cloth layer, thereby greatly improving the removal effect of the tin ash on the surface of the tin-plated copper wire of the present invention.

[0023] 4) Loading holes are respectively arranged at the centers of the first ash removal roller and the third ash removal roller of the present invention, and damping particles for vibration reduction are respectively filled in the loading holes. The openings of the loading holes are respectively closed by corresponding covers. Under the friction energy consumption of the damping particles for vibration reduction, a good vibration reduction effect is formed to perform vibration reduction and vibration isolation on the tin-plated copper wire wound around the first ash removal roller and the third ash removal roller, so as to prevent the normal tin plating process and normal transmission of the tin-plated copper wire from being affected, thereby greatly improving the practical effect of the present invention.

[0024] 5) Cross beams are respectively fixedly connected horizontally to the bracket at positions corresponding to the first N-shaped member and the second N-shaped member. Driving oil cylinders are fixedly connected to the cross beams. The first N-shaped member on which the first ash removal roller and the third ash removal roller are installed and the connecting rod member on which the second ash removal roller is installed are respectively fixedly connected to the piston rod ends of the corresponding driving oil cylinders. In this way, the positions of the first ash removal roller, the second ash removal roller, and the third ash removal roller can be adjusted. Then, corresponding wiping cloth winding shafts are respectively rotatably installed on the cross beams, and the buffer wiping cloth layer is respectively wound around the first ash removal roller, the second ash removal roller, and the third ash removal roller by winding. After each use for a time t1, the wiping cloth winding shaft winds up the buffer wiping cloth layer by a length L1, and the contact position between the buffer wiping cloth layer and the tin-plated copper wire can be replaced. Then, when the piston column of the driving oil cylinder extends by a length L2, a thickness compensation can be formed for the output buffer wiping cloth layer, so that the copper wire can continuously abut against the surface of the buffer wiping cloth layer in a reasonable tension state, thereby achieving a better tin ash removal effect while not affecting the normal ash removal of the tin-plated copper wire.

[0025] 6) The winding direction of the buffer wiping cloth layer of the present invention is set opposite to the conveying direction of the copper wire, so as to ensure that the buffer wiping cloth layer does not displace when wiping the surface of the tin-plated copper wire, thereby ensuring the practical effect of the present invention.

[0026] 7) The tin ash removal mechanism of the present invention has a mounting seat plate fixedly connected to the outer side of the bracket, and a plurality of tension adjustment mechanisms for individually adjusting the tension of each copper wire are fixedly connected side by side on the mounting seat plate, which include an adjustment seat and a fixed shaft rotatably mounted on the adjustment seat, a group of limiting side plates are symmetrically and rotatably mounted on the middle part of the fixed shaft, corresponding rubber gaskets are respectively fixedly connected inwardly on opposite sides of the limiting side plates, and a corresponding arc-shaped limiting ring is fixedly sleeved on the fixed shaft between the limiting side plates, both sides of the arc-shaped limiting ring are respectively fixed to the rubber gaskets, and the middle part of the arc-shaped limiting ring is respectively arranged in the shape of an inner concave arc surface, and the copper wire is wound around the arc-shaped limiting ring and then wound up by an external winding mechanism; on this basis, the present invention further arranges the fixed shaft in a hollow tubular shape, and an opening is arranged on the fixed shaft facing the contact position between the arc-shaped limiting ring and the copper wire, and a distance measuring sensor is fixedly installed in the fixed shaft, which can pass through the opening and faces the contact position between the arc-shaped limiting ring and the copper wire. When in use, the copper wire is wound around the arc limit ring and then enters the feed end of the winding mechanism for winding. During this process, the copper wire forms a downward pressure on the arc limit ring under the action of its tension, causing a certain downward pressure deformation amount at the contact position between the arc limit ring and the copper wire. The distance between the distance measuring sensor and the contact position between the arc limit ring and the copper wire is detected in real time, so that the tension of the copper wire can be obtained in real time.

[0027] The distance range between the distance measuring sensor and the arc limit ring can be set according to the tension requirement of the copper wire. When the distance between the distance measuring sensor and the arc limit ring is less than the distance range value, it is judged that the tension of the copper wire is greater than the set requirement. At this time, the tension of the copper wire can be reduced by extending the piston rod of the oil cylinder; when the distance between the distance measuring sensor and the arc limit ring is greater than the distance range value, it is judged that the tension of the copper wire is less than the set requirement. At this time, the tension of the copper wire can be increased by retracting the piston rod of the oil cylinder, thereby effectively, quickly and accurately controlling the winding tension of the copper wire.

[0028] 8) The tension adjustment mechanism of the present invention has a low space occupancy rate. During use, the adjustment cylinders can be installed side by side on the mounting base plate, and then multiple tinned copper wires output side by side can be overlapped on the corresponding arc-shaped limit rings of the tension adjustment mechanism respectively, so that the tension of multiple copper wires output side by side can be adjusted separately.

[0029] 9) The two sides of the arc-shaped limit ring of the present invention are respectively integrally formed with clamping protrusions that are compatible with the installation groove of the rubber gasket, and the clamping protrusions are fixedly clamped into the installation groove, and the contact surface between the clamping protrusion and the installation groove is fixed by gluing, thereby ensuring the connection stability between the clamping protrusion and the installation groove. After the arc-shaped limit ring is deformed by force, it can produce a certain amount of deformation itself, and it can form a certain amount of pulling deformation on the rubber gasket, thereby adapting to the force formed by the tension of the copper wire on the arc-shaped limit ring, so as to ensure the practical effect of the present invention.

[0036] For the convenience of those skilled in the art to understand, the embodiments will be further described in detail in conjunction with the drawings for the structure of the present invention:

[0037] Refer to Figure 1-6 , a copper wire tin plating processing device, including

[0038] A tin plating furnace 1, including a tin plating box body 101, a molten tin cavity 1011 is arranged in the tin plating box body 101, and a heater 1012 for heating the molten tin cavity 1011, a butt roller 102 is installed on the bottom side of the middle part of the molten tin cavity 1011, and a copper wire inlet roller 103 and a copper wire outlet roller 104 are arranged on both sides of the tin plating box body 101;

[0039] The copper wire cooling mechanism 2 comprises an air inlet slot 201 fixed on the upper side of the tin melting chamber 1011, the opening of the air inlet slot 201 is arranged downward, and a corresponding cooling water circulation pipe 202 is fixed downward in the middle of the air inlet slot 201. During use, the air inlet end of the air inlet slot 201 is connected to an external fan, and the cooling water circulation pipe 202 is connected to an external water source. The cooling water circulation pipe 202 is arranged in a wave shape, and the top of the cooling water circulation pipe 202 is fixed to the top surface of the air inlet slot 201, and the bottom of the cooling water circulation pipe 202 extends to the lower side of the opening of the air inlet slot 201; the opening of the air inlet slot 201 is sealed with a corresponding cover 203. The cover 203 is provided with corresponding clearance grooves 2031 at positions corresponding to the cooling water circulation pipe 202. The bottom of the cooling water circulation pipe 202 extends to the outside of the cover 203 through the clearance grooves 2031. The two sides of the clearance grooves 2031 are respectively connected to the outside in a U shape with corresponding air guide plates 204. The cross-section of the air guide plates 204 is arc-shaped and covers the outside of the corresponding cooling water circulation pipe 202. The copper wire enters the tin melting chamber 1011 through the copper wire inlet roller 103, passes through the bottom side of the abutment rod 102, and then passes through the hollow position of the air guide plates 204, and is output outward along the copper wire outlet roller 104.

[0040] During the tinning process, the copper wire enters the tin melting chamber 1011 through the copper wire inlet roller 103, passes through the bottom side of the abutment rod 102, and then passes through the hollow position of the air guide plate 204, and is output outward along the copper wire outlet roller 104. When the copper wire passes through the hollow position of the air guide plate 204, the circulating air is guided by each give way groove 2031 and the U-shaped air guide plate 204, and is concentratedly blown to the hollow position of the air guide plate 204, so as to quickly and evenly cool the copper wire that has just been tinned, so as to significantly reduce the problem of increased elongation of the tinned copper wire due to temperature increase, thereby effectively improving the quality of the tinned copper wire.

[0041] The circulating air is mainly concentrated on the hollow position of the air guide plate 204, thereby preventing the copper wire tinning operation from being affected by the addition of the copper wire cooling mechanism 2; and the circulating gas will pass through the cooling water circulation pipe 202 arranged in a wave shape before blowing to the hollow position of the air guide plate 204, thereby reducing the temperature of the gas blown to the copper wire, so as to further significantly improve the cooling effect on the copper wire that has just completed tinning.

[0042] The copper wire tin plating processing device further includes a tin ash removal mechanism. The tin ash removal mechanism includes a bracket 301 arranged on one side of the discharge end of the copper wire outlet roller 104. The bracket 301 is rotatably provided with a first ash removal roller 302, a second ash removal roller 303, and a third ash removal roller 304 at intervals. Corresponding buffer wiping cloth layers 4 are respectively sleeved on the first ash removal roller 302, the second ash removal roller 303, and the third ash removal roller 304. Both sides of the first ash removal roller 302 and the third ash removal roller 304 are respectively rotatably installed on both sides of corresponding first n-shaped members 5, and the first n-shaped members 5 are vertically movably installed on the bracket 301. Both ends of the second ash removal roller 303 are respectively rotatably installed on both sides of corresponding second n-shaped members 6. A connecting rod 8 installed with an ultrasonic transducer 7 is fixedly connected upward in the middle of the second n-shaped member 6. The connecting rod 8 is vertically movably installed on the bracket 301, and the ultrasonic transducer 7 is connected to an external ultrasonic generator. The copper wire sequentially passes around the top side of the first ash removal roller 302, the bottom side of the second ash removal roller 303, and the top side of the third ash removal roller 304 and then is output outward.

[0043] During the tin ash removal process, under the action of the ultrasonic transducer 7, the second ash removal roller 303 can ultrasonically vibrate the copper wire after tin plating, so as to remove the tin ash attached to the surface of the tin-plated copper wire, separate the tin ash with high viscosity from the tin-plated copper wire, and enable it to be wiped off by the buffer wiping cloth layer 4, thereby greatly improving the removal effect of the tin ash on the surface of the tin-plated copper wire of the present invention.

[0044] Filling holes are respectively arranged at the centers of the first ash removal roller 302 and the third ash removal roller 304. The filling holes are respectively filled with damping particles 9 for vibration reduction, and the openings of the filling holes are respectively closed by corresponding covers 10. The damping particles 9 for vibration reduction are made of iron-based spherical particles.

[0045] Under the friction energy consumption of the damping particles 9 for vibration reduction, a good vibration reduction effect is formed to reduce and isolate the vibration of the tin-plated copper wire passing around the first ash removal roller 302 and the third ash removal roller 304, so as to prevent the normal tin plating process and normal transmission of the tin-plated copper wire from being affected, thereby greatly improving the practical effect of the present invention.

[0046] The bracket 301 is transversely fixed with corresponding cross beams 11 at positions corresponding to the first N-shaped member 5 and the second N-shaped member 6. Corresponding driving cylinders 12 are fixedly connected to the cross beams 11. The first N-shaped member 5 and the connecting rod member 8 are respectively fixedly connected to the piston rod ends of the corresponding driving cylinders 12. Corresponding wiping cloth winding shafts 13 are rotatably installed on the cross beams 11, and the wiping cloth winding shafts 13 are driven by corresponding driving motors 14. The buffer wiping cloth layer 4 is respectively wound around the first ash removal roller 302, the second ash removal roller 303, and the third ash removal roller 304 in a winding manner. The winding direction of the buffer wiping cloth layer 4 is set opposite to the conveying direction of the copper wire. The output end of the buffer wiping cloth layer 4 is pulled to the corresponding wiping cloth winding shaft 13 for winding. After each use duration t1, the driving motor 14 drives the wiping cloth winding shaft 13 to wind the buffer wiping cloth layer 4 by a length L1, and the piston rod of the driving cylinder 12 extends by a length L2, so that the copper wire is continuously tensioned against the surface of the buffer wiping cloth layer 4.

[0047] In this embodiment, after each use duration of 20 - 40 minutes, the driving motor 14 drives the wiping cloth winding shaft 13 to wind the buffer wiping cloth layer 4 by a length of 2 - 5 cm, and the piston rod of the driving cylinder 12 extends by a length of 5 - 10 mm (the actual thickness of the buffer wiping cloth layer 4), so that the copper wire is continuously tensioned against the surface of the buffer wiping cloth layer 4.

[0048] The bracket 301 of the present invention is transversely fixed with cross beams 11 at positions corresponding to the first N-shaped member 5 and the second N-shaped member 6. Driving cylinders 12 are fixedly connected to the cross beams 11. The first N-shaped member 5 equipped with the first ash removal roller 302 and the third ash removal roller 304, and the connecting rod member 8 equipped with the second ash removal roller 303 are respectively fixedly connected to the piston rod ends of the corresponding driving cylinders 12. In this way, the positions of the first ash removal roller 302, the second ash removal roller 303, and the third ash removal roller 304 can be adjusted. Then, corresponding wiping cloth winding shafts 13 are rotatably installed on the cross beams 11 respectively, and the buffer wiping cloth layer 4 is respectively wound around the first ash removal roller 302, the second ash removal roller 303, and the third ash removal roller 304 in a winding manner. After each use for a period of time, the wiping cloth winding shaft 13 winds a small section of the used buffer wiping cloth layer 4, and the contact position between the buffer wiping cloth layer 4 and the tinned copper wire can be replaced, which is very convenient. At the same time, the piston rod of the driving cylinder 12 extends a small distance to adapt to the unwinding thickness of the buffer wiping cloth layer 4, so as to form a thickness compensation for the output buffer wiping cloth layer 4, so that the copper wire can be continuously and reasonably tensioned against the surface of the buffer wiping cloth layer 4, so as to achieve a better tin ash removal effect while not affecting the normal ash removal of the tinned copper wire.

[0049] The winding direction of the buffer wiping cloth layer 4 is set opposite to the conveying direction of the tinned copper wire, so as to ensure that the buffer wiping cloth layer 4 does not displace when wiping the surface of the tinned copper wire, thereby ensuring the practical effect of the present invention.

[0050] A corresponding mounting seat plate 15 is fixedly connected to the outside of the bracket of the tin ash removing mechanism, and a plurality of tension adjusting mechanisms 16 for individually adjusting the tension of each copper wire are fixedly connected side by side on the mounting seat plate 15.

[0051] The tension adjusting mechanism 16 includes an adjusting seat 1601 and a fixed shaft 1602 rotatably mounted on the adjusting seat 1601. The adjusting seat 1601 is driven by an adjusting oil cylinder 1603 installed on the mounting seat plate. A group of limiting side plates 1604 are symmetrically and rotatably mounted in the middle of the fixed shaft 1602. Rubber gaskets 1605 are fixedly connected inwardly on the opposite sides of the limiting side plates 1604 respectively. An arc-shaped limiting ring 1606 is fixedly sleeved on the fixed shaft 1602 between the limiting side plates 1604. The two sides of the arc-shaped limiting ring 1606 are respectively fixed to the rubber gaskets 1605. The middle part of the arc-shaped limiting ring 1606 is arranged in an inward concave arc shape. The copper wire passes around the arc-shaped limiting ring 1606 and is then wound by an external winding mechanism. The fixed shaft 1602 is arranged in a hollow tubular shape, and an opening 17 is provided on the fixed shaft 1602 opposite to the contact position between the arc-shaped limiting ring 1606 and the copper wire. A distance measuring sensor 1607 is fixedly installed in the fixed shaft 1602 and can pass through the opening 17 and be opposite to the contact position between the arc-shaped limiting ring 1606 and the copper wire.

[0052] During use, the tinned copper wire passes around the arc-shaped limiting ring 1606 and then enters the feeding end of the winding mechanism for winding. During this process, the copper wire forms a downward pressure on the arc-shaped limiting ring 1606 under the action of its tension, causing a certain downward deformation amount at the contact position between the arc-shaped limiting ring 1606 and the copper wire. By detecting the distance between the distance measuring sensor 1607 and the contact position between the arc-shaped limiting ring 1606 and the copper wire in real time, the tension of the copper wire can be obtained in real time. According to the tension requirement of the tinned copper wire, the distance range between the distance measuring sensor 1607 and the arc-shaped limiting ring 1606 is set. When the distance between the distance measuring sensor 1607 and the arc-shaped limiting ring 1606 is less than the distance range value, it is determined that the tension of the tinned copper wire is greater than the set requirement. At this time, the piston rod of the adjusting oil cylinder 1603 can be extended to reduce the tension of the copper wire. When the distance between the distance measuring sensor 1607 and the arc-shaped limiting ring 1606 is greater than the distance range value, it is determined that the tension of the tinned copper wire is less than the set requirement. At this time, the piston rod of the adjusting oil cylinder can be retracted to increase the tension of the tinned copper wire, so that the winding tension of the tinned copper wire can be effectively, quickly and accurately controlled.

[0053] The space occupancy rate of the tension adjusting mechanism 16 of the present invention is low. During use, its adjusting oil cylinder 1603 can be arranged side by side on the mounting seat plate 15, and then multiple tinned copper wires output side by side are respectively connected to the arc-shaped limiting rings 1606 of the corresponding tension adjusting mechanisms 16, so as to separately adjust the tensions of the multiple copper wires output side by side.
