Description

Technical Field

[0001] This invention relates to the field of metal wire surface treatment technology, specifically to an environmentally friendly copper wire tin plating equipment and tin plating process. Background Technology

[0002] Copper wire has excellent electrical conductivity and is widely used in electrical connections, electronic components, and cables. To improve the surface properties of copper wire, it is usually tin-plated, which coats the outer periphery of the copper wire with a tin layer. This improves the solderability of the copper wire and provides a certain degree of protection to the surface.

[0003] Existing copper wire tinning equipment typically includes a solution frame for holding molten tin and a traction component for moving the copper wire. The copper wire enters the molten tin under the pull of the traction component, causing the molten tin to adhere to its outer circumference. After the copper wire leaves the molten tin, its outer circumference carries some excess molten tin. Therefore, a scraping structure needs to be installed at the point where the copper wire leaves the molten tin to remove the excess molten tin from its outer circumference. Since copper wires have different specifications and varying diameters, the limiting position of the copper wire and the position of the scraping structure need to be adjusted when tinning copper wires of different diameters.

[0004] Existing copper wire limiting structures and solder molten metal scraping structures are usually independent of each other. After changing to copper wires of different diameters, the limiting structure and scraping structure need to be adjusted separately, increasing the equipment adjustment process. At the same time, after the position of the scraping structure is adapted to the copper wire diameter, the distance between it and the copper wire will affect the amount of solder molten metal scraped off the outer periphery of the copper wire. Adjusting the position for the copper wire diameter and adjusting the position for the amount of solder molten metal scraped can easily affect each other, making it inconvenient to adjust the copper wire adaptation position and the solder scraping position separately.

[0005] Therefore, there is a need for an environmentally friendly copper wire tin plating equipment that allows the copper wire limiting position and scraping position to be adjusted synchronously with changes in the copper wire diameter, and that the distance between the scraper and the copper wire can be adjusted separately after the copper wire diameter is adapted, while reducing interference between multiple limiting wheels and scrapers during movement. Summary of the Invention

[0006] The main objective of this invention is to provide an environmentally friendly copper wire tin plating equipment and tin plating process, which aims to solve the problems of existing copper wire tin plating equipment requiring separate adjustment of the limiting structure and scraping structure when adapting to copper wires of different diameters, and the inconvenience of adjusting the scraping spacing after the scraping structure has completed diameter adaptation.

[0007] To achieve the above objectives, the technical solution provided by this invention is as follows: An environmentally friendly copper wire tin plating device includes a mounting housing, a solution frame disposed inside the mounting housing for containing molten tin, and a traction component for moving the copper wire. The solution frame is equipped with a detection component and a scraping component. The detection assembly includes two mounting plates spaced apart in the vertical direction, multiple connecting plates that slide radially along the mounting plates, and a driving component that drives the multiple connecting plates to move synchronously. The mounting plates are connected to the solution frame. The center of the mounting plates is provided with a through hole for copper wires to pass through. Each connecting plate is rotatably provided with a limiting wheel for contacting the outer peripheral surface of the copper wire. The scraping assembly includes a second mounting plate, multiple connecting blocks that slide radially along the second mounting plate, multiple connecting frames that correspond one-to-one with the multiple connecting blocks, and a second driving component for driving the multiple connecting blocks to move synchronously. The second mounting plate is connected to the solution frame. The center of the second mounting plate is provided with a through hole for copper wires to pass through. The connecting frames are provided with scrapers for abutting against the outer circumference of the copper wires. A linkage rod is provided between drive component one and drive component two. The linkage rod is used to drive multiple connecting blocks to move synchronously along the radial direction of mounting plate two when multiple connecting plates move radially along mounting plate one. A spacing adjustment component is provided between the connecting block and the corresponding connecting frame. The spacing adjustment component is used to drive the connecting frame to move relative to the corresponding connecting block in order to adjust the spacing between the scraper and the copper wire.

[0008] Specifically, a plurality of guide grooves are provided on the mounting plate one along its radial direction, the connecting plate is slidably disposed in the corresponding guide groove one and extends along the axial direction of the mounting plate one, and an elastic element is provided between the connecting plate and the mounting plate one; The driving component includes a driving disk rotatably mounted on an upper mounting plate. The driving disk has driving grooves corresponding to multiple connecting plates. The connecting plates have guide posts slidably mounted in the driving grooves. The multiple driving grooves are eccentrically positioned relative to the rotation center of the driving disk.

[0009] Specifically, the mounting plate 2 has multiple guide grooves 2 along its radial direction, the connecting block is slidably disposed in the corresponding guide groove 2, the driving component 2 includes a driving disk 2 rotatably disposed on the mounting plate 2, the driving disk 2 is provided with driving grooves 2 corresponding to the multiple connecting blocks, the connecting block is provided with guide post 2 slidably disposed in the corresponding driving groove 2, and the multiple driving grooves 2 are eccentrically disposed relative to the rotation center of the driving disk 2.

[0010] Specifically, the connecting frame is slidably disposed in the guide groove 2, and the spacing adjustment component includes a lead screw rotatably disposed on the connecting block. The connecting frame is provided with a threaded hole that engages with the lead screw thread. The lead screw extends radially along the mounting plate 2 and passes through the mounting plate 2. The end of the lead screw located on the outer side of the mounting plate 2 is provided with a linkage gear 3. A drive disk 3 is coaxially rotatably disposed on the outer side of the mounting plate 2. The drive disk 3 is provided with an annular rack that meshes simultaneously with the gears on multiple lead screws.

[0011] Specifically, the first and second drive disks are respectively equipped with a first linkage gear and a second linkage gear, and the linkage rod is equipped with a linkage rack that meshes with the first and second linkage gears respectively, so that when the first drive disk moves, it drives the second drive disk to move through the linkage rod.

[0012] Specifically, multiple limiting wheels on the same connecting plate are spaced apart along the axial direction of mounting plate one, and the limiting wheels on two circumferentially adjacent connecting plates are staggered in the axial direction of mounting plate one; the scrapers on two adjacent connecting frames are staggered in the axial direction of mounting plate two.

[0013] Specifically, the scraper is inclined relative to the radial direction of the mounting plate 2, the side of the scraper near the through hole 2 is higher than the side away from the through hole 2, and the side of the scraper near the copper wire is provided with a guide plate extending downward in the vertical direction.

[0014] Specifically, the solution frame is equipped with two sets of guiding components, which are located at the position where the copper wire enters the molten tin and the position where it leaves the molten tin, so that the copper wire moves horizontally and is immersed in the molten tin after entering the molten tin.

[0015] Specifically, a sleeve is provided between the two mounting plates, and the sleeve is fitted over the outside of multiple connecting plates. A heating component for preheating the copper wire is provided inside the sleeve.

[0016] An environmentally friendly tin plating process for copper wire, using the aforementioned environmentally friendly tin plating equipment for copper wire, includes the following steps: S1. Pass the copper wire through the detection component, solution frame and scraping component in sequence, and move the copper wire by pulling the traction component. S2. Drive multiple connecting plates to move radially along mounting plate one by driving component one, so that multiple limit wheels cooperate with the outer circumferential surface of copper wire, and drive multiple connecting blocks to move synchronously radially along mounting plate two by spacing adjustment component. S3. By changing the direction of movement of the copper wire through the guide component, the copper wire passes through the molten tin in the solution frame and a tin layer is formed on the outer periphery of the copper wire. S4. Adjust the position of the connecting frame relative to the corresponding connecting block by adjusting the spacing component, so that a preset spacing is formed between multiple scrapers and copper wires, and use multiple scrapers to scrape off excess solder around the copper wires during the movement of the copper wires. S5. The scraped molten solder is guided away from the copper wire by the guide plate on the scraper, so that the scraped molten solder flows back into the solution frame.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The detection component drives the limit wheels to move synchronously through multiple connecting plates that move radially along the mounting plate, thus changing the positional relationship between the limit wheels and the copper wire. Simultaneously, the drive disc drives the connecting blocks in the scraping component to move synchronously via a linkage rod, allowing the limit wheels and scraper to adjust accordingly to changes in the copper wire diameter.

[0018] 2. The connecting block in the scraping assembly is used to adjust the base position of the scraper. The connecting frame can move relative to the connecting block via a lead screw, so that the distance between the scraper and the copper wire can be further adjusted. Therefore, the degree of scraping of the copper wire molten tin by the scraper can be changed according to the tin plating requirements.

[0019] 3. The scraper is set at an angle, so that the scraped solder can move away from the copper wire along the scraper. With the help of the guide plate, the solder flows downward and back into the solution frame, reducing the possibility of the scraped solder re-adhering to the outer surface of the copper wire.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] Reference Figures 1 to 10 An environmentally friendly copper wire tinning device includes a mounting housing 1, a solution frame 2 disposed within the mounting housing 1 for containing molten tin, a traction component 3 for moving the copper wire, a detection component 4, and a scraping component 5. The detection component 4 and the scraping component 5 are respectively positioned along the movement path of the copper wire through the solution frame 2. The detection component 4 is designed to mate with the outer circumference of the copper wire to accommodate copper wires of different diameters, while the scraping component 5 is used to scrape off excess molten tin from the outer circumference of the copper wire after it has passed through the molten tin. The traction component 3 drives the copper wire to move continuously along a predetermined path, causing the copper wire to sequentially pass through the detection component 4, the solution frame 2, and the scraping component 5.

[0033] Reference Figures 1 to 3 As shown, the mounting housing 1 is hollow, and the solution frame 2 is fixedly installed inside the mounting housing 1. A hot water inlet pipe and a drain pipe (not shown in the figure) are also connected inside the mounting housing 1 to ensure the temperature of the molten solder.

[0034] Reference Figures 2 to 6The detection component 4 includes two mounting plates 41, a fixing plate 44, multiple connecting plates 42, and a driving component 43. The two mounting plates 41 are vertically spaced apart and connected to the sidewall of the solution frame 2 via the fixing plate 44, positioning them before the copper wire enters the molten tin in the solution frame 2. Each mounting plate 41 has a circular plate structure with its axis vertically aligned. A through hole 411 is formed at the center of each mounting plate 41, allowing the copper wire to pass through it. Multiple guide grooves 412 are formed radially on each mounting plate 41, evenly distributed around its circumference. The connecting plates 42 are slidably disposed within corresponding guide grooves 412, extending axially along the mounting plates 41 and slidably connected to them, enabling the connecting plates 42 to move radially along the mounting plates 41.

[0035] Each connecting plate 42 is provided with a limiting wheel 45 on the side facing the axis of the mounting plate 41. The rotation axis of the limiting wheel 45 is perpendicular to the axis of the mounting plate 41. After the copper wire passes through the through hole 411, it is located between multiple limiting wheels 45. The limiting wheel 45 can contact the outer circumference of the copper wire and rotates with the copper wire during the movement of the copper wire to reduce the sliding friction between the limiting wheel 45 and the copper wire.

[0036] An elastic element 46 is provided between the connecting plate 42 and the mounting plate 41. One end of the elastic element 46 is connected to the connecting plate 42, and the other end is connected to the mounting plate 41. The elastic element 46 is configured to make the connecting plate 42 tend to move toward the axis of the mounting plate 41, thereby causing the limiting wheel 45 provided on the connecting plate 42 to tend to approach the copper wire.

[0037] Multiple connecting plates 42 can move along their respective guide grooves 412. The synchronous movement of the connecting plates 42 changes the distribution of multiple limiting wheels 45 around the copper wire, allowing the limiting wheels 45 to engage with the outer circumference of copper wires of different diameters. A guide post 47 extending vertically is provided on the upper side of the connecting plate 42. The driving component 43 includes a driving disk 431. The driving disk 431 is rotatably mounted on the upper mounting plate 41. The rotation axis of the driving disk 431 coincides with the axis of the mounting plate 41. Multiple driving grooves 4311 are formed on the driving disk 431, each corresponding to one of the connecting plates 42, and are eccentrically positioned relative to the rotation center of the driving disk 431. The guide post 47 is slidably disposed within its corresponding driving groove 4311. When the drive disc 431 rotates, the groove wall of the drive groove 4311 pushes the guide post 47 to move along the corresponding guide groove 412, so that multiple connecting plates 42 move closer to or further away from the axis of the mounting plate 41, thereby synchronously changing the relative position between multiple limit wheels 45 and the copper wire.

[0038] In this embodiment, the mounting plate 41 has four guide grooves 412 and four corresponding connecting plates 42. Multiple limiting wheels 45 are spaced apart along the axial direction of the mounting plate 41 on each connecting plate 42. The limiting wheels 45 on two circumferentially adjacent connecting plates 42 are staggered in the axial direction of the mounting plate 41, so that adjacent circumferentially adjacent limiting wheels 45 are not in exactly the same axial position. When the drive disc 431 rotates and moves the multiple connecting plates 42 toward the axis of the mounting plate 41, the limiting wheels 45 on adjacent connecting plates 42 can contact different positions on the outer circumference of the copper wire using the staggered axial positions, thereby reducing interference between adjacent limiting wheels 45 during movement.

[0039] Reference Figures 7 to 10 The scraping assembly 5 includes a mounting plate 51, a fixing plate 52 mounted on the mounting plate 51, multiple connecting blocks 53, multiple connecting frames 54, and a driving component 55. The mounting plate 51 is fixedly connected to the side wall of the solution frame 2 via the fixing plate 52. The mounting plate 51 is located on the movement path of the copper wire after it leaves the molten solder. The mounting plate 51 has a circular plate structure with its axis set vertically. A through hole 511 is opened in the center of the mounting plate 51, through which the copper wire can pass. Multiple guide grooves 512 are opened radially on the mounting plate 51. The multiple guide grooves 512 are evenly distributed around the circumference of the mounting plate 51. The connecting blocks 53 are slidably disposed in the corresponding guide grooves 512, allowing the connecting blocks 53 to move radially along the mounting plate 51. The connecting frames 54 are correspondingly disposed with the connecting blocks 53, and a scraper 56 is fixedly disposed on the connecting frames 54. The scraper 56 is disposed on the side of the connecting frame 54 facing the axis of the mounting plate 2 51 and is used to mate with the outer peripheral surface of the copper wire. Multiple connecting frames 54 are evenly distributed along the circumference of the mounting plate 2 51, so that multiple scrapers 56 can contact the outer peripheral surface of the copper wire from different circumferential positions. After the copper wire passes through the molten solder, it passes through multiple scrapers 56 along its movement path. The scrapers 56 can contact the outer peripheral surface of the copper wire during the movement of the copper wire and scrape off the excess molten solder adhering to the outer peripheral surface of the copper wire.

[0040] The driving component 2 55 includes a driving disk 2 551 rotatably mounted on the mounting plate 2 51. The driving disk 2 551 is coaxially mounted with the mounting plate 2 51. Multiple driving grooves 2 5511 are formed on the driving disk 2 5511. Each driving groove 2 5511 corresponds to a multiple connecting block 53. Each connecting block 53 has a guide post 2 57 extending vertically. The guide post 2 57 is slidably disposed within its corresponding driving groove 2 5511. The multiple driving grooves 2 5511 are eccentrically positioned relative to the rotation center of the driving disk 2 551. When the driving disk 2 551 rotates, the groove walls of the driving grooves 2 5511 push the guide post 2 57 to move, causing the multiple connecting blocks 53 to move synchronously along their corresponding guide grooves 2 512. This synchronously changes the distance between the multiple connecting blocks 53 and the axis of the mounting plate 2 51, allowing the connecting frame 54 and the scraper 56 mounted on the connecting frame 54 to synchronously change their radial positions with the connecting blocks 53.

[0041] The connecting frame 54 is slidably disposed within the corresponding guide groove 512. The connecting frame 54 and the corresponding connecting block 53 are movable relative to each other along the radial direction of the mounting plate 51. A spacing adjustment assembly 8 is provided between the connecting block 53 and the connecting frame 54. The spacing adjustment assembly 8 includes a lead screw 81. The lead screw 81 is rotatably disposed on the connecting block 53 and extends radially along the mounting plate 51. A threaded hole is provided on the connecting frame 54 to engage with the lead screw 81. The lead screw 81 passes through the threaded hole on the connecting frame 54 and extends outward through the mounting plate 51. A linkage gear 82 is provided at the end of the lead screw 81 located on the outer side of the mounting plate 51. Since the connecting frame 54 is restricted from moving in the radial direction along the guide groove 512, when the lead screw 81 rotates, the threaded engagement between the lead screw 81 and the connecting frame 54 causes the connecting frame 54 to move axially along the lead screw 81, thereby changing the position of the connecting frame 54 relative to the corresponding connecting block 53, and thus changing the distance between the scraper 56 installed on the connecting frame 54 and the copper wire.

[0042] A drive disk 83 is coaxially rotatably mounted on the outer side of mounting plate 2 51. A ring rack is provided on the side of drive disk 3 83 facing the lead screw 81, and the linkage gears 3 82 on multiple lead screws 81 mesh with the ring rack. When drive disk 3 83 rotates relative to mounting plate 2 51, the ring rack drives the multiple linkage gears 3 82 to rotate synchronously, causing the multiple lead screws 81 to rotate synchronously, and causing the multiple connecting brackets 54 to move synchronously relative to their corresponding connecting blocks 53, thereby synchronously changing the spacing between the multiple scrapers 56 and the copper wire. By rotating drive disk 3 83, the position of the scrapers 56 can be adjusted while the position of the connecting blocks 53 remains unchanged, allowing the spacing between the scrapers 56 and the copper wire to be adjusted according to the desired soldering degree.

[0043] The scrapers 56 on two adjacent connecting frames 54 are staggered in the axial direction of the mounting plate 51, so that adjacent scrapers 56 have different positions in the axial direction. When multiple connecting blocks 53 move synchronously in the radial direction along the mounting plate 51, the connecting frames 54 and scrapers 56 move with the connecting blocks 53. By staggering adjacent scrapers 56 in the axial direction, the possibility of adjacent scrapers 56 contacting each other during radial movement can be reduced. Multiple scrapers 56 respectively cooperate with different circumferential positions on the outer periphery of the copper wire, and excess molten solder at different positions on the outer periphery of the copper wire can be scraped off when the copper wire passes through multiple scrapers 56. In this embodiment, the guide groove 512 is set to eight, and eight connecting blocks 53 and eight connecting frames 54 are correspondingly set. The scrapers 56 on the eight connecting frames 54 are distributed around the copper wire to cooperate with different positions on the outer periphery of the copper wire.

[0044] The scraper 56 is inclined relative to the radial direction of the mounting plate 51. The side of the scraper 56 near the through hole 511 is higher than the side away from the through hole 511, so that the molten solder scraped off after the scraper 56 contacts the copper wire can flow along the scraper 56 toward the side away from the through hole 511. A guide plate 58 extending vertically downward is provided on the side of the scraper 56 near the copper wire. The guide plate 58 is located on the side of the copper wire. After the molten solder scraped off by the scraper 56 flows outward along the scraper 56, it flows downward under the guidance of the guide plate 58, so that the scraped molten solder is away from the movement path of the copper wire and flows back into the solution frame 2. This reduces the possibility of the scraped molten solder continuing to flow downward along the outer periphery of the copper wire and re-adhering to the outer periphery of the copper wire.

[0045] Reference Figure 2 and Figure 3 The detection component 4 and the scraping component 5 are connected by a linkage rod 91. This linkage rod transmits the rotation of the first drive disk 431 to the second drive disk 551, so that when the position of the limiting wheel 45 in the detection component 4 is adjusted, the position of the connecting block 53 in the scraping component 5 can be adjusted synchronously. Through this linkage, when the diameter of the copper wire changes, the scraper 56 can move accordingly with the connecting block 53 while adjusting the position of the limiting wheel 45, and the third drive disk 83 can further adjust the position of the connecting frame 54 relative to the connecting block 53.

[0046] The linkage rod 91 is slidably mounted on mounting plate 41 and mounting plate 51. A first linkage gear 92 and a second linkage gear 93 are respectively provided on the outer periphery of drive disc 431 and drive disc 551. A linkage rack is provided on the linkage rod 91 near the first linkage gear 92 and the second linkage gear 93, meshing with them, so that the rotation of drive disc 431 can be transmitted to drive disc 551 through the linkage rod 91. The sliding of the linkage rod 91 on mounting plate 41 and mounting plate 51 restricts its direction of movement, ensuring that the linkage rod 91 remains engaged with the first linkage gear 92 and the second linkage gear 93 during movement.

[0047] When tin plating copper wires of different diameters is required, firstly, drive disk 431 is rotated. Drive disk 431 drives multiple connecting plates 42 to move synchronously along the radial direction of mounting plate 41 via drive groove 4311 and guide post 47, causing multiple limit wheels 45 to move to positions that mate with the outer circumference of the copper wire. Simultaneously with the rotation of drive disk 431, linkage gear 92 rotates with drive disk 431. Linkage gear 92 meshes with the corresponding linkage rack on linkage rod 91, causing linkage rod 91 to move along mounting plate 41 and mounting plate 51. After linkage rod 91 moves, it drives drive disk 551 to rotate via another linkage rack meshing with linkage gear 93. Drive disk 551 drives multiple connecting blocks 53 to move synchronously along the radial direction of mounting plate 51 via drive groove 5511 and guide post 57, thereby causing scraper 56 to change position synchronously with connecting blocks 53. Therefore, while adjusting the limiting wheel 45 to accommodate the copper wire diameter, the connecting block 53 in the scraping assembly 5 can move synchronously, allowing the position of the scraper 56 to be adjusted accordingly as the copper wire diameter changes. This ensures that the detection assembly 4 and the scraping assembly 5 maintain a corresponding radial adjustment relationship.

[0048] Reference Figure 3 The solution frame 2 is equipped with two sets of guide components 6, which are respectively set at the position where the copper wire enters the molten tin and the position where the copper wire leaves the molten tin, and are used to change the direction of movement of the copper wire.

[0049] When the traction component 3 pulls the copper wire, the copper wire first passes the detection component 4 located above the molten solder. Then, under the action of the guide component 6 near the molten solder inlet, the copper wire changes its direction of movement, moving from a vertical direction to a horizontal direction, and then passes horizontally through the molten solder in the solution frame 2. After passing through the molten solder, the copper wire changes its direction of movement again under the action of another set of guide components 6 near the molten solder outlet, moving the copper wire from a horizontal direction to a vertical direction, and then moves towards the scraping component 5.

[0050] The two sets of guiding components 6 each include a guide wheel and a guide wheel frame. The guide wheel frame is slidably mounted inside the solution frame 2, and the guide wheel is rotatably mounted on the guide wheel frame. The outer circumferential surface of the guide wheel engages with the copper wire. When the copper wire passes through the guide wheel, the copper wire drives the guide wheel to rotate, and the direction of movement is changed under the guidance of the outer circumferential surface of the guide wheel. The guide wheel located at the position where the copper wire enters the molten solder guides the copper wire into the molten solder, while the guide wheel located at the position where the copper wire leaves the molten solder guides the copper wire that has passed through the molten solder to the outside of the solution frame 2, allowing the copper wire to move continuously along a predetermined path. When installing the copper wire, the guide wheel can be moved upward by the guide wheel frame to facilitate the installation of the copper wire.

[0051] Reference Figure 2 and Figure 4 A sleeve 7 is fixedly disposed between two mounting plates 41. The sleeve 7 is coaxially disposed with the mounting plates 41. The sleeve 7 is hollow and located on the outside of the plurality of connecting plates 42. A heating component (not shown in the figure) is disposed inside the sleeve 7. The sleeve 7 is heated, thereby preheating the copper wire passing through the sleeve 7.

[0052] Reference Figure 3 As shown, the traction component 3 and the guide component 6 are correspondingly arranged, and the detection component 4 and the scraping component 5 are correspondingly arranged between the traction component 3 and the guide component 6. This allows the copper wire to pass through the detection component 4 and the scraping component 5 in a vertical state.

[0053] An environmentally friendly copper wire tin plating process, using the aforementioned environmentally friendly copper wire tin plating equipment, includes the following steps: S1. Pass the copper wire through the detection component 4, the solution frame 2 and the scraping component 5 in sequence, and move the copper wire by pulling the traction component 3. S2. Drive multiple connecting plates 42 to move radially along mounting plate 41 via driving component 43, so that multiple limiting wheels 45 cooperate with the outer peripheral surface of copper wire, and drive multiple connecting blocks 53 to move synchronously radially along mounting plate 51 via linkage mechanism. S3. The direction of movement of the copper wire is changed by the guide component 6, so that the copper wire passes through the molten tin in the solution frame 2 and a tin layer is formed on the outer periphery of the copper wire. S4. Adjust the position of the connecting frame 54 relative to the corresponding connecting block 53 by adjusting the spacing mechanism so that the multiple scrapers 56 form a corresponding spacing with the copper wire, and use the multiple scrapers 56 to scrape off the excess solder around the copper wire during the movement of the copper wire. S5. The scraped molten solder is guided away from the copper wire by the guide plate 58 on the scraper 56, so that the scraped molten solder flows back into the solution frame 2.

[0054] The specific working method is as follows: When using this equipment to tin-plat copper wire, first install the copper wire onto the traction assembly 3, and then pass the copper wire sequentially through the detection assembly 4, sleeve 7, solution frame 2, and scraping assembly 5. Depending on the diameter of the copper wire to be processed, rotate the drive disk 431. The drive disk 431, through the cooperation of the drive groove 4311 and the guide post 47, drives multiple connecting plates 42 to move synchronously along the radial direction of the mounting plate 41, causing multiple limiting wheels 45 to move to positions that mate with the outer circumference of the copper wire, thereby restricting the movement of the copper wire.

[0055] When drive disk 431 rotates, the rotation of drive disk 431 is transmitted to drive disk 551 through linkage rod 91, causing drive disk 551 to rotate synchronously. Drive disk 551, through the cooperation of drive groove 5511 and guide post 57, drives multiple connecting blocks 53 to move radially along mounting plate 51, causing connecting frame 54 and scraper 56 to move synchronously with connecting blocks 53, thereby allowing scraper 56 to adjust the base position according to the change of copper wire diameter.

[0056] Then, adjust the position of the scraper 56 according to the required tin layer thickness after tin plating of the copper wire. Rotate the drive disk 3 83, which simultaneously drives multiple linkage gears 3 82 to rotate through the ring rack. The linkage gears 3 82 drive the corresponding lead screws 81 to rotate. The lead screws 81 engage with the threaded holes on the connecting frame 54, causing the connecting frame 54 to move relative to the connecting block 53, thereby changing the distance between the scraper 56 and the outer circumference of the copper wire.

[0057] After the traction component 3 is started, the traction wheel drives the copper wire to move continuously. After passing the detection component 4, the copper wire enters the sleeve 7. The heating component preheats the copper wire. The copper wire then passes through the first set of guide components 6 and enters the molten tin in the solution frame 2. It moves horizontally in the molten tin, so that the molten tin adheres to the outer circumference of the copper wire. After passing through the second set of guide components 6, the copper wire leaves the molten tin and moves towards the scraping component 5.

[0058] As the copper wire passes through the scraping assembly 5, multiple scrapers 56 engage with different circumferential positions on the outer surface of the copper wire to scrape off excess molten tin carried on the outer circumference. The scraped molten tin moves away from the copper wire along the inclined direction of the scraper 56 and flows downward under the guidance of the guide plate 58, eventually flowing back into the solution frame 2. After passing through the scraping assembly 5, the copper wire continues to be pulled to the subsequent station by the traction assembly 3, thus completing continuous tin plating.

[0059] When the specifications of the copper wire change, the drive disc 431 can be readjusted to make the limit wheel 45 and the connecting block 53 adjust their radial positions synchronously. On this basis, the position of the connecting frame 54 relative to the connecting block 53 can be adjusted by the drive disc 83 to keep the scraper 56 and the copper wire at the appropriate distance, thereby adapting to the tin plating process of copper wires of different diameters.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
