Abstract
Description
Technical Field
[0001] This invention relates to the field of copper wire processing technology, and more specifically to a continuous tin plating and annealing apparatus for copper wire. Background Technology
[0002] During the production of copper wire, a copper wire tinning and annealing device is needed to process the copper wire to enhance its performance. A continuous copper wire tinning and annealing device is a piece of equipment that integrates both copper wire annealing and tinning processes, aiming to improve the conductivity, ductility, and corrosion resistance of the copper wire. This device achieves continuous processing of copper wire by controlling temperature, time, and the tinning process.
[0003] A search revealed that CN219136885U discloses a copper wire annealing and tin plating device, including a heating block, a first motor, a guide drive shaft, a cooling box, a tin plating device, a take-up device, a second motor, a rotating shaft, a take-up wheel, a base, a cleaning roller, and copper wire. This invention utilizes a tin plating device that seals the tin plating box with a sealing cover. A fan draws gas into a purification box, where a diluent dilutes the tin plating gas. A pressing mechanism presses the copper wire down, allowing it to penetrate deeper into the tin plating bath, extending the tin plating time and improving both the working environment and the quality of the plating. The pressing mechanism uses a cylinder to push a slide table down a support plate, which in turn pushes a push rod downwards. The push rod presses down a pressure plate, forcing the copper wire deeper into the tin plating bath. Brushes on the pressure plate clean the copper wire, further enhancing the tin plating effect.
[0004] When tinning copper wires, the molten tin is placed in a tin storage tank. Pulling the copper wire allows the molten tin in the tank to tin-plate it. However, the molten tin in the tank is stable and does not flow. Prolonged stagnation may cause impurities to settle or accumulate in the molten tin, affecting the tinning effect. Furthermore, the lack of flow in the molten tin leads to insufficient mass transfer, significantly reducing the tinning speed and requiring more time to obtain a sufficient coating thickness, thus affecting work efficiency. Summary of the Invention
[0005] The purpose of this invention is to provide a continuous tin plating annealing device for copper wires, which solves the problems that the tin liquid in the tin storage tank is stable and has no flow. Long-term stasis may cause impurities to precipitate or accumulate in the tin liquid, affecting the tin plating effect. In addition, the lack of flow of the tin liquid will lead to insufficient mass transfer capacity, and the tin plating speed will be significantly reduced, requiring a longer time to obtain a sufficient plating thickness, thus affecting work efficiency.

The pneumatic diaphragm pump is fixedly installed on one side of the support plate.
[0012] Preferably, the recycling component further includes a top plate and a connecting plate. One end of the top plate is fixedly installed on the top of the inner wall of the protective shell. Both ends of the connecting plate are fixedly installed on the inner side of the top plate. A molten solder flow pipe is fixedly installed on the inner side of the top plate. A groove is formed on one side of the top plate. Multiple moving rods are rotatably connected to the groove through bearings.

[0014] Preferably, a rotating rod is rotatably connected to the inner wall of the slot, a waterproof motor is fixedly installed inside the protective shell, and the output end of the waterproof motor is fixedly installed on the rotating rod.
[0015] Preferably, multiple turntables are inserted into the rotating rod, and circular sponge pads are fixedly installed on the inner side of each of the multiple turntables. An extrusion plate is fixedly installed on one side of the inner wall of the slot, and a brush rod is fixedly installed at the bottom of the water tank, with the brush rod inserted into the circular sponge pad.
[0016] Preferably, a heating furnace is fixedly installed at the bottom of the inner wall of the protective shell, and a heating box is fixedly installed on the upper surface of the protective shell, with one end of the heating furnace connected to the bottom of the heating box through a heat transfer pipe.
[0017] Preferably, a layered plate is fixedly installed inside the heating box. A heating port is opened on one side of the layered plate.

[0018] Preferably, a support leg is fixedly installed on the lower surface of the protective shell, and heat dissipation vents are provided on both sides of the protective shell.
[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0020] 1. A pneumatic diaphragm pump forces molten solder through the nozzle onto a stainless steel inclined plate, which then flows onto a corrugated plate. The corrugated plate's design creates turbulence in the solder, breaking the laminar flow. This turbulence enhances the mixing of the flow, making the solder flow more uniform and improving its wetting ability on the copper wire. Because the stainless steel inclined plate is tilted, the solder remains in a constant flow state. The filter holes within the baffle also filter impurities, allowing the flowing solder to carry away these impurities and retain them on the baffle, maintaining the cleanliness of the solder. Furthermore, the high fluidity increases the contact area between the solder and the copper wire, resulting in faster tinning and the formation of a thicker plating layer in a short time, thus improving work efficiency.
[0021] 2. After tin plating, the molten tin can flow into the filter box along the stainless steel inclined plate. It is then filtered by the filter plate in the filter box and enters the bottom of the filter box. Then, the molten tin can be pumped into the nozzle by the pneumatic diaphragm pump, realizing the recycling of molten tin and saving resources.
[0022] 3. Rotate the turntable so that the circular sponge pads on both sides hold the copper wire and wipe the copper wire after tinning. After wiping, the sponge pads enter the water tank. The sponge pads can be cleaned by the brush rod. After cleaning, the sponge pads will be squeezed out of the water by the squeezing plate, so that the sponge pads can be reused to wipe the tinned copper wires. This avoids the sponge pads accumulating a lot of impurities after long-term use, which would affect the tinning of the copper wires.
[0023] 4. When the hot gas in the heating furnace enters the heating box, pull the push plate to move the adjusting plate along the slide groove, so that the first air outlet or the second air outlet in the adjusting plate corresponds to the heating port, and perform annealing treatment on the copper wire set at one end of the heating port. In this way, the temperature can be controlled by the first air outlet and the second air outlet to achieve annealing treatment of the copper wire and make the annealing of the copper wire more stable.

Detailed Implementation
[0033] In the description of this invention, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.
[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0035] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.
[0036] Example 1
[0037] This invention proposes the following technical solution: a conductive copper wire straightening and winding device, such as... Figure 1 and Figure 3 As shown, the system includes a protective housing 1, with a nozzle 2 installed on one side of the protective housing 1; a tin plating assembly 3, which is installed inside the protective housing 1 and is used to tin-plat the surface of copper wires. The tin plating assembly 3 includes a support plate 31 and an inclined component. The support plate 31 is fixedly installed inside the protective housing 1, and the inclined component is located on one side of the support plate 31. The inclined component includes a stainless steel inclined plate 32 fixed to the inclined surface of the support plate 31. Multiple corrugated plates 33 are fixedly installed on the upper surface of the stainless steel inclined plate 32, and a baffle 34 is fixedly installed on the upper surface of the stainless steel inclined plate 32. The baffle 34 is inserted into the multiple corrugated plates 33. A filter hole 35 and a limiting groove are respectively opened on one side of the baffle 34, and a rubber ring 36 is bonded in the limiting groove; and a recycling assembly 4, which is located on one side of the support plate 31 and is used to reuse the molten tin.
[0038] In use, molten tin flows out from the filter box 41 and is sprayed out from the nozzle 2 to tin-plate the copper wire. During the tin-plating process, the molten tin flows downward along the corrugated plate 33. The bending design of the corrugated plate 33 can cause turbulence in the molten tin, thereby breaking the laminar flow state. Turbulence helps to enhance the mixing of the flow, making the molten tin flow more uniform and improving the wetting ability of the copper wire. At the same time, since the stainless steel inclined plate 32 is in an inclined position, the molten tin can always be in a flowing state, allowing impurities on the copper wire to be washed down. When the molten tin flows to the filter hole 35 in the baffle 34, it will filter the impurities and leave them on the baffle 34. This not only prevents impurities from settling but also keeps the molten tin clean. Moreover, due to the high fluidity of the molten tin, the contact area between the molten tin and the copper wire is increased, which can make the tin plating speed faster and form a thicker plating layer in a short time, improving work efficiency.
[0039] Example 2
[0040] This invention proposes the following technical solution: a conductive copper wire straightening and winding device, such as... Figure 1 and Figure 3 As shown, the recycling component 4 includes a filter box 41 and a pneumatic diaphragm pump 42. The filter box 41 is fixedly installed on the bottom of the inner wall of the protective shell 1. A filter plate 43 is fixedly installed inside the filter box 41. The pneumatic diaphragm pump 42 is fixedly installed on one side of the support plate 31. The recycling component 4 also includes a top plate 44 and a connecting plate 45. One end of the top plate 44 is fixedly installed on the top of the inner wall of the protective shell 1. Both ends of the connecting plate 45 are fixedly installed inside the top plate 44. A molten solder flow pipe 46 is fixedly installed inside the top plate 44. A groove is opened on one side of the top plate 44. Multiple moving rods 47 are rotatably connected in the groove through bearings. The multiple moving rods 47 are connected to the molten solder flow pipe 46 through silicone hoses. A flow channel is opened inside the moving rod 47 and the flow channel is connected to the nozzle 2. Both ends of the pneumatic diaphragm pump 42 are fixedly installed on the molten solder flow pipe 46 and the filter box 41 through silicone hoses, respectively.
[0041] After tin plating is completed, the molten tin flows along the stainless steel inclined plate 32 into the filter box 41. The filter plate 43 in the filter box 41 filters the molten tin, allowing it to enter the bottom of the filter box 41. This drives the pneumatic diaphragm pump 42, which draws the molten tin out of the filter box 41 and into the molten tin flow pipe 46. The molten tin then flows along the silicone hose into the nozzle 2, enabling the molten tin to be reused and saving resources.
[0042] Example 3
[0043] This invention proposes the following technical solution: a conductive copper wire straightening and winding device, such as... Figure 1 and Figure 3As shown, a water storage tank 5 is fixedly installed at the bottom of the protective shell 1. A slot 6 is opened at the bottom of the inner wall of the protective shell 1 and is connected to the water storage tank 5. A water outlet pipe 7 is fixedly installed on one side of the water storage tank 5. A valve 8 is fixedly installed on the outside of the water outlet pipe 7. A rotating rod 9 is rotatably connected to the inner wall of the slot 6. A waterproof motor 10 is fixedly installed inside the protective shell 1, and the output end of the waterproof motor 10 is fixedly installed on the rotating rod 9. Multiple turntables 11 are inserted into the rotating rod 9. A circular sponge pad 12 is fixedly installed on the inner side of each of the multiple turntables 11. A squeezing plate 13 is fixedly installed on one side of the inner wall of the slot 6. A brush rod 14 is fixedly installed at the bottom of the water storage tank 5 and is inserted into the circular sponge pad 12.
[0044] The waterproof motor 10 is started, driving the turntable 11 to rotate. This causes the circular sponge pads 12 inside the turntable 11 to rotate, and the copper wire is clamped in the circular sponge pads 12 on both sides. When the tinned copper wire is pulled, it can be wiped. The wiped circular sponge pads 12 enter the water tank 5 as the turntable 11 rotates. The brush rod 14 can clean the rotating circular sponge pads 12. After cleaning, the circular sponge pads 12 will rotate to the position of the squeezing plate 13. The squeezing plate 13 can squeeze out the water in the circular sponge pads 12, so that the cleaned circular sponge pads 12 can continue to wipe the tinned copper wire. This allows the circular sponge pads 12 to continuously wipe the tinned copper wire, preventing the circular sponge pads 12 from accumulating a lot of impurities after long-term use and requiring regular replacement. This not only keeps the tinned copper wire cleaner but also improves work efficiency.
[0045] Example 4
[0046] This invention proposes the following technical solution: a conductive copper wire straightening and winding device, such as... Figure 1 and Figure 3 As shown, a heating furnace 15 is fixedly installed on the bottom of the inner wall of the protective shell 1, and a heating box 16 is fixedly installed on the upper surface of the protective shell 1. One end of the heating furnace 15 is connected to the bottom of the heating box 16 through a heat transfer pipe. A layered plate 17 is fixedly installed inside the heating box 16. A heating port 18 is opened on one side of the layered plate 17. A sliding groove is opened on the lower surface of the layered plate 17. An adjusting plate 19 is slidably connected in the sliding groove. A first air outlet 20 and a second air outlet 21 are opened on one side of the adjusting plate 19. A push plate 22 is inserted into the heating box 16, and one end of the push plate 22 passes through the sliding groove and is fixedly installed on the adjusting plate 19. A protective cover 23 is fixedly installed on the upper surface of the layered plate 17. A support leg 24 is fixedly installed on the lower surface of the protective shell 1. Heat dissipation vents 25 are opened on both sides of the protective shell 1.
[0047] Starting the heating furnace 15 allows hot air to enter the bottom of the heating chamber 16 through the heat transfer pipe. Pulling the push plate 22 allows the adjusting plate 19 to move along the slide groove in the layered plate 17, thereby moving the first air outlet 20 or the second air outlet 21 in the adjusting plate 19 to the position of the heating port 18, corresponding to the heating port 18. This allows heat to be transferred to the copper wire for annealing through the heating port 18. The heat of the copper wire annealing can be controlled through the first air outlet 20 and the second air outlet 21, making the annealing of the copper wire more stable. The protective cover 23 can retain heat and prevent heat loss.

Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
