Description

Technical Field

[0001] The invention relates to the field of tinned copper wire processing equipment, in particular to integrated tinned copper wire processing and manufacturing equipment. Background Art

[0002] Tinned copper wire, a core material in the electronics and electrical fields, has a processing quality that directly impacts the performance and reliability of end products. In traditional processing techniques, equipment at each stage is independently distributed, requiring manual coordination throughout the entire process, from unwinding the copper wire to tinning, curing, and cooling. This results in low production efficiency and poor quality consistency. In surface treatment, static polishing or chemical cleaning struggle to completely remove the oxide layer and oil stains, resulting in insufficient adhesion of the tin coating. The use of a single heating temperature during the curing stage can cause the tin coating to solidify rapidly, leaving residual solvent inside. This can lead to defects such as bubbles and cracks, severely impacting the density of the coating.

[0003] In existing technologies, design flaws in the cooling system further hinder process improvement. Traditional spray cooling relies on external power to drive the water flow, resulting in high energy consumption and uneven cooling. Sudden cooling of the copper wire can easily cause stress cracking in the coating. Furthermore, the large amount of waste heat generated during the solidification process is not effectively utilized, resulting in energy waste. Furthermore, when processing multiple strands of copper wire simultaneously, the linkage between the various processes is insufficient, making continuous production impossible and making it difficult to meet the demands of modern industrialization for efficient, energy-saving, and intelligent manufacturing.

[0013] The present invention provides an integrated processing and manufacturing device for tinned copper wire. It has the following beneficial effects: 1.

[0014] 2. The present invention increases the width of the heat conduction plate in the curing chamber from left to right, forming a low-temperature, medium-temperature, and high-temperature gradient curing environment. In the low-temperature stage, surface moisture and low-boiling-point solvents are slowly evaporated to avoid boiling and bubbling. In the medium-temperature stage, the volatilization of medium-boiling-point solvents is accelerated to promote the initial melting and diffusion of the tin layer. In the high-temperature stage, the diffusion of tin and copper atoms is promoted to form intermetallic compounds, which enhances the bonding strength and completely cures the coating. This avoids the problems of "rapid surface curing and internal solvent residue" (such as bubbles, cracks, and hollow structures) caused by traditional direct high-temperature curing, and improves the uniformity and density of the coating.

At the same time, the waste heat of the curing chamber is used to drive the transmission system, which drives the rotating rod and the brush plate to rotate, breaking the cooling water into small water droplets. The small water droplets evaporate quickly when they come into contact with the high-temperature copper wire. The principle of evaporation and heat absorption is used to achieve efficient cooling. Compared with traditional spray cooling, the cooling speed is faster and the energy consumption is lower, avoiding stress cracking of the coating caused by sudden cooling.

Conductive electrodes are set on both sides of the tank body for electroplating tin on the copper wire passing through. A fixing frame 3 is fixedly installed on one side of the top of the processing table 1, and a plurality of grinding chambers 4 are fixedly installed in the middle of the fixing frame 3. The grinding chambers 4 are disc-shaped and hollow inside to form a grinding cavity. The number of the grinding chambers 4 can be set to 3-5 according to the processing requirements and arranged in series in the horizontal direction. The inside of the grinding chambers 4 is provided with magnetic abrasives 5. The magnetic abrasives 5 are a mixture of iron sand and aluminum oxide particles with a particle size of 2-5 mm, which can be passed through Directed movement is achieved through the magnetic field attraction of the magnetic ring 8. A first threading hole 6 is provided in the middle of the grinding chamber 4. The diameter of the first threading hole 6 is 1-2 mm larger than the outer diameter of the copper wire to ensure that the copper wire passes through smoothly and the abrasive does not leak out. A movable shaft 7 is movably installed in the middle of the inner end of the two adjacent grinding chambers 4. The movable shaft 7 is fixed to the side wall of the grinding chamber 4 through a bearing seat and can rotate freely around the horizontal axis. Magnetic rings 8 are fixedly installed on the outer diameter of both sides of the movable shaft 7. The magnetic rings 8 are neodymium iron boron permanent magnets with N / S poles evenly distributed in the circumferential direction to form a magnetic attraction field with the magnetic abrasive 5. A curing chamber 14 is fixedly installed on the other side of the top of the processing table 1 to solidify the solidified material 5. A heating rod 15 is fixedly installed on the upper side of the interior of the curing chamber 14. The heating rod 15 is a quartz heating tube with adjustable power. The temperature in the curing chamber 14 is accurately controlled by the temperature control system. A plurality of curing chambers 16 are opened on the lower side of the interior of the curing chamber 14. The number of curing chambers 16 corresponds to the number of polishing chambers 4. Multiple strands of copper wire can be cured at the same time. A heat conducting plate 17 is fixedly installed inside the curing chamber 16, and the width of the heat conducting plate 17 increases from left to right. The heat conducting plate 17 is made of aluminum alloy, forming a heat conduction area that increases from left to right. A second threading hole 18 is opened on both sides of the bottom of the curing chamber 14 and the lower side of the interior of each curing chamber 16. The second threading hole 18 is coaxially aligned with the first threading hole 6 to ensure that the copper wire passes through each functional module in a straight line. A cooling chamber 19 is fixedly installed at one end of the curing chamber 14 away from the copper wire tinning tank 2. A plurality of cooling cavities 20 are opened at the bottom end of the cooling chamber 19. The cooling cavities 20 correspond to the curing chambers 16 one by one, and an independent cooling space is formed inside. A short shaft 21 is movably installed on the top of the cooling cavity 20.

The shape of the brush plate is cross-shaped, which can break the cooling water into small water droplets when rotating at high speed.

[0020] Specifically, by starting the heating rod 15 for heating, the temperature of the heating rod 15 will be transferred to each curing cavity 16 through the heat conducting plate 17, heating and curing the tin plating layer, and accelerating the volatilization of the surface solvent. The width of the heat conducting plate 17 in the curing cavity 16 increases from left to right, causing the temperature in the curing cavity 16 to gradually increase. The initial low-temperature stage slowly evaporates surface moisture and low-boiling-point solvents to avoid boiling and bubbling. The middle-term medium-temperature stage accelerates the volatilization of the medium-boiling-point solvent, and at the same time causes the tin layer to initially melt and diffuse to form a preliminary bond. The final high-temperature stage promotes the diffusion of tin and copper atoms to form intermetallic compounds, enhances the bonding force, and completely solidifies the coating.

The branch pipe 24 is a hose with an inner diameter of 8 mm, which can evenly spray cooling water. A cooling water inlet pipe 25 is fixedly installed in the middle of the multi-way pipe 23. The cooling water inlet pipe 25 is connected to an external cooling water source, and a flow control valve is set at the inlet.

[0024] Furthermore, a first chamber 26 is fixedly installed on one side of the top of the curing chamber 14.

[0026] Furthermore, a transmission shaft 36 is movably mounted on the top of the curing chamber 14 through a bearing seat. The transmission shaft 36 is horizontally arranged and fixed to the top of the curing chamber 14 through two deep groove ball bearings. A first cam 37 is fixedly mounted on the outer diameter of one side of the transmission shaft 36. The first cam 37 is a disc cam. The contour curve is designed according to the stroke of the piston rod, which pushes the first connecting rod 38 to swing back and forth. The end of the first cam 37 is movably mounted with a first connecting rod 38, and the end of the first connecting rod 38 is movably mounted on the outer end of the first piston rod 29. The two ends of the first connecting rod 38 are respectively hinged to the first cam 37 and the first piston rod 29 through a pin to form a cam-link mechanism. A second cam 39 is fixedly mounted on the outer diameter of the other side of the transmission shaft 36. The second cam 39 has a phase difference of 180 degrees with the first cam 37. °, ensuring that the two groups of pistons move synchronously and in opposite directions, the end of the second cam 39 is movably mounted with a second connecting rod 40 and the end of the second connecting rod 40 is movably mounted on the outer end of the second piston rod 34, the structure of the second connecting rod 40 is the same as that of the first connecting rod 38, forming a symmetrical transmission structure, a worm 41 is fixedly mounted on the middle outer diameter of the transmission shaft 36, the module of the worm 41 is 2, the number of teeth is 40, and a reduction transmission is formed with the worm gear 44, and a rotating shaft 43 is movably mounted on the top of the curing chamber 14 near the lower position of the transmission shaft 36 through a bearing seat, the rotating shaft 43 is vertically arranged and intersects the transmission shaft 36 at right angles, a worm gear 44 is fixedly mounted on one end of the rotating shaft 43 and the worm gear 44 is meshed and connected with the inner end of the worm 41, the number of teeth of the worm gear 44 is 80, and it cooperates with the worm 41 to achieve a 2:1 reduction ratio.

[0027] Furthermore, the other end of the rotating shaft 43 is fixedly mounted with a driving bevel gear 45, which has 20 teeth and a module of 3, and forms a 90° right-angle transmission with the driven bevel gear 47. A rotating rod 46 is movably mounted on the inner top of the cooling chamber 19. The rotating rod 46 is fixed to the top of the cooling chamber 19 through a thrust ball bearing and can rotate vertically. The top of the rotating rod 46 extends to the outside of the cooling chamber 19 and is fixedly mounted with a driven bevel gear 47.

The middle transmission gear 48 serves as a driving wheel and drives the gears on both sides to rotate through meshing to achieve power distribution.

[0028] Specifically, the solidified tinned copper wire enters the lower part of the cooling chamber 19, at which time cooling water is introduced through the cooling water inlet pipe 25 and discharged into each cooling chamber 20 through the multi-way pipe 23 and the branch pipe 24, and the heat in the solidification chamber 14 is also conducted to the first cylinder 27 through the heat conductor 28. The air in the first cylinder 27 expands rapidly due to the heat, pushing the displacer 30 to move outward, and driving the first piston rod 29 to move. The first piston rod 29 drives one end of the first connecting rod 38 to move accordingly, so that the other end of the first connecting rod 38 drives the transmission shaft 36 to rotate through the first cam 37. The rotating transmission shaft 36 will drive the first piston rod 29 and the displacer 30 inward in the opposite direction through the first cam 37, and the gas in the first cylinder 27 is discharged into the second chamber 32 through the first chamber 26 and the connecting pipe 42. The gas is quickly dissipated in the second chamber 32 through the heat dissipation fins 33, resulting in the second chamber 3 2, the internal air pressure decreases, and the external atmospheric pressure pushes the piston block 35 to move inward. At the same time, the displacer 30 is driven to the outer end of the first cylinder body 27. The gas in the second chamber 32 is reversely expelled into the first cylinder body 27 through the connecting pipe 42 and the first chamber 26, and expands again by absorbing heat. This process is circulated continuously, driving the rotating shaft 43 to rotate continuously. The rotating rotating shaft 43 drives the driving bevel gear 45 to rotate, and drives the driven bevel gear 47 and the rotating rod 46 to rotate through meshing transmission. The rotating rod 46 drives one of the transmission gears 48 to rotate, thereby driving all the transmission gears 48 and the short shaft 21 to rotate. The short shaft 21 drives all the brush plates 22 to rotate at high speed, breaking the cooling water entering the cooling chamber 20 into fine water droplets. These fine water droplets fall to the surface of the tinned copper wire under the influence of weight. When they come into contact with the copper wire surface, they are affected by the high temperature and evaporate rapidly. The copper wire surface is quickly cooled by the principle of evaporation and heat absorption.

[0029] Furthermore, a unwinding bracket 49 is fixedly installed on one side of the top of the processing table 1 near the fixed frame 3. The unwinding bracket 49 is a "door"-shaped steel structure, and a bearing seat is arranged inside to support the unwinding roller 50. The unwinding roller 50 is movably installed inside the unwinding bracket 49, and the surface of the unwinding roller 50 is provided with anti-slip grooves, which can fix multiple strands of copper wire coils. A winding bracket 51 is fixedly installed on one end of the top of the processing table 1 near the curing chamber 14. The winding bracket 51 has the same structure as the unwinding bracket 49 and is arranged at the end of the equipment. A winding roller 52 is movably installed inside the winding bracket 51. The winding roller 52 is a hollow shaft structure, and the copper wire can be tensioned by a pneumatic device. A winding motor 53 is fixedly installed on one side of the winding bracket 51, and the driving end of the winding motor 53 is fixedly installed on one end of the winding roller 52. The winding motor 53 is a servo motor equipped with an encoder, which can accurately control the winding tension and line speed.

[0030] Working principle: multiple strands of copper wire are pulled out through the unwinding roller 50, and passed through the corresponding first threading hole 6 and second threading hole 18 and then wound on the winding roller 52, and the winding motor 53 is started to wind the copper wire, and then the DC motor 13 is started, and the DC motor 13 drives the long shaft 9 to rotate, driving all the active wheels 10 on the long shaft 9 to rotate, and through the transmission of the synchronous belt 12, drives all the driven wheels 11 and the movable shaft 7 to rotate, and the rotating movable shaft 7 will drive the magnetic rings 8 on both sides to rotate, and the magnetic rings 8 will attract the magnetic abrasive 5 inside the grinding chamber 4, so that it moves with the magnetic ring 8, and use the continuously moving magnetic abrasive 5 to grind the outer surface of the copper wire passing through, remove the oxide layer, oil stains and other impurities on the surface of the copper wire, improve the adhesion of the tin plating, and the polished copper wire can be After being treated with external cleaning and drying equipment, the copper wire enters the copper wire tinning tank 2 for surface electrotinning. After the tinning is completed, the copper wire enters the curing chamber 14 through the second threading hole 18, and then the heating rod 15 is started for heating. The temperature of the heating rod 15 will be transmitted to each curing cavity 16 through the heat conducting plate 17 to heat and cure the tinned layer, accelerating the volatilization of the surface solvent. The width of the heat conducting plate 17 in the curing cavity 16 increases from left to right, causing the temperature in the curing cavity 16 to gradually increase. The initial low-temperature stage slowly evaporates surface moisture and low-boiling-point solvents to avoid boiling and bubbling. The mid-term medium-temperature stage accelerates the volatilization of the medium-boiling-point solvent and makes the tin layer initially melt and diffuse to form a preliminary bond. The final high-temperature stage promotes the bonding of tin and copper. Atomic diffusion forms intermetallic compounds, which enhances the bonding strength and completely solidifies the coating. This can avoid the rapid solidification of the tin layer surface caused by direct solidification, while the internal solvent is not fully volatilized, forming bubbles, cracks or a "hollow" structure. The solidified tinned copper wire enters the bottom of the cooling chamber 19. At this time, cooling water is introduced through the cooling water inlet pipe 25 and discharged into each cooling cavity 20 through the multi-way pipe 23 and the branch pipe 24. The heat in the solidification chamber 14 will also be conducted to the first cylinder 27 through the heat conductor 28. The air in the first cylinder 27 expands rapidly due to the heat, pushing the displacer 30 to move outward and driving the first piston rod 29 to move. The first piston rod 29 drives one end of the first connecting rod 38 to move accordingly, so that the other end of the first connecting rod 38 passes through The first cam 37 drives the transmission shaft 36 to rotate. The rotating transmission shaft 36 will drive the first piston rod 29 and the displacer 30 inward in the opposite direction through the first cam 37, and the gas in the first cylinder 27 is displaced into the second chamber 32 through the first chamber 26 and the connecting pipe 42. The gas in the second chamber 32 is quickly dissipated through the heat dissipation fins 33, resulting in a decrease in the air pressure in the second chamber 32. The external atmospheric pressure pushes the piston block 35 inward. At the same time, the displacer 30 is driven to the outer end of the first cylinder 27. The gas in the second chamber 32 is displaced into the first cylinder 27 in the opposite direction through the connecting pipe 42 and the first chamber 26, and expands again by absorbing heat. This process is circulated continuously, driving the rotating shaft 43 to rotate continuously. The rotating rotating shaft 43 drives the active bevel gear 45 to rotate.The meshing transmission drives the driven bevel gear 47 and the rotating rod 46 to rotate. The rotating rod 46 then drives one of the transmission gears 48 to rotate, thereby driving all the transmission gears 48 and the short shaft 21 to rotate. The short shaft 21 drives all the brush plates 22 to rotate at high speed, breaking the cooling water entering the cooling chamber 20 into small water droplets. These small water droplets fall to the surface of the tinned copper wire due to the influence of weight. When they come into contact with the copper wire surface, they are affected by the high temperature and evaporate quickly. The copper wire surface is quickly cooled by the principle of evaporation and heat absorption. After cooling, the tinned copper wire is reeled by the reeling roller 52.
