Technical Field

[0001] This utility model relates to the field of copper wire tin plating technology, specifically to a tin plating device for copper wire processing. Background Technology

[0002] Tin plating of copper wire involves plating a layer of metallic tin onto the surface of the copper wire. This treatment not only enhances the conductivity of the copper wire but also significantly improves its corrosion resistance and oxidation resistance, thereby extending the service life of low-voltage cables. During the processing of copper wire, a tin plating device is used to tin the surface of the copper wire.

[0003] However, in current tin plating equipment, the electrolyte in the tin plating bath is static when tin plating copper wires, resulting in an uneven distribution of electrolyte concentration. This easily leads to uneven thickness of the tin plating on the surface of the copper wire, affecting the quality of the tin plating process. Furthermore, the tin plating bath has a certain depth, making the arrangement and distribution of copper wires within the bath inconvenient. Therefore, we propose a tin plating device for copper wire processing to solve the aforementioned problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: a tin plating device for copper wire processing, comprising a tin plating tank 1, a feed pipe 2 rotatably connected to the left side of the tin plating tank 1, a discharge pipe 3 rotatably connected to the right side of the tin plating tank 1, and positioning rollers 4 rotatably connected to the opposite ends of the feed pipe 2 and the discharge pipe 3; a limit roller 20 rotatably connected to the lower ends of the first connecting frame 14 and the second connecting frame 16, and stirring rods 21 installed on the opposite sides of the first connecting frame 14 and the second connecting frame 16;

[0026] Furthermore, the limiting roller 20 and the positioning roller 4 are located in the same vertical plane. There are two limiting rollers 20 and two positioning rollers 4 symmetrically arranged about the longitudinal center line of the connecting rod 15. The limiting rollers 20 and the positioning rollers 4 are used to limit the copper wire and make it tensioned in the tin plating bath 1.

[0027] A first support frame 10 is installed above the feed pipe 2. A servo motor 11 is installed at the upper end of the first support frame 10. A lead screw 12 is connected to the output end of the servo motor 11. The lower end of the lead screw 12 is rotatably connected to the feed pipe 2. A first mounting plate 13 is threaded to the outer side of the lead screw 12. A first connecting frame 14 is connected to the outer side of the first mounting plate 13. A connecting rod 15 is connected to the upper end of the first connecting frame 14. A second connecting frame 16 is installed at the end of the connecting rod 15. A second mounting plate 17 is connected to the end of the second connecting frame 16. A second support frame 18 is installed above the discharge pipe 3. A sliding rod 19 is connected between the second support frame 18 and the discharge pipe 3. The sliding rod 19 passes through the second mounting plate 17.

[0028] Further, the second mounting plate 17 is slidably connected to the sliding rod 19. The sliding rod 19 and the lead screw 12 are arranged in parallel. The sliding rod 19 can be used to limit the movement of the first mounting plate 13 and the second mounting plate 17 to ensure their vertical movement.

[0029] Further, a mounting frame 6 is installed on the left side of the tin plating tank 1. A driving motor 7 is installed on the left side of the mounting frame 6. The output end of the driving motor 7 is connected to a turntable 8. A convex block 9 is connected to the side surface of the turntable 8.

[0030] Furthermore, a regulating plate 5 is installed above the feed pipe 2. The convex block 9 slidably penetrates through the interior of the regulating plate 5. The regulating plate 5 has a "hui" - shaped structure, enabling the convex block 9 to smoothly slide within the regulating plate 5 and拨动 the regulating plate 5, causing the feed pipe 2 to rotate.

[0031] Furthermore, the convex block 9 is arranged at a position near the edge of the turntable 8. The contact surfaces between the convex block 9 and the regulating plate 5 are smooth, which can reduce the frictional force between the convex block 9 and the regulating plate 5. When the convex block 9 rotates following the turntable 8, it拨动 the regulating plate 5.

[0032] Specifically, the copper wire enters through the feed pipe 2 and exits through the discharge pipe 3. The servo motor 11 is powered on, and the servo motor 11 is controlled to rotate forward, thereby controlling the rotation of the lead screw 12 connected to the output end. The lead screw 12 controls the downward movement of the first mounting plate 13 thread - connected to the outside. At this time, the first connecting frame 14 installed outside the first mounting plate 13 moves downward synchronously. The first connecting frame 14 is connected to the second connecting frame 16 through the connecting rod 15. Therefore, the second connecting frame 16 can be driven to move downward. The second mounting plate 17 connected to the second connecting frame 16 slides on the sliding rod 19, restricting the vertical downward movement of the first connecting frame 14 and the second connecting frame 16, thereby driving the limiting roller 20 to move downward. The limiting roller 20 presses the copper wire, pressing a section of the copper wire to a position slightly below the interior of the tin plating tank 1 and limiting it through the positioning roller 4. An electrolyte containing tin ions is placed in the tin plating tank 1. The copper wire is immersed in the electrolyte containing tin ions, and an electric current is passed through to reduce the tin ions and deposit tin on the surface of the copper wire. The servo motor 11 is controlled to rotate in reverse, thereby controlling the reverse rotation of the lead screw 12, and further controlling the upward movement of the first mounting plate 13, causing the first connecting frame 14, the connecting rod 15, and the second connecting frame 16 to move upward, controlling the upward movement and reset of the limiting roller 20, facilitating the subsequent arrangement of the copper wire.

[0033] When the drive motor 7 is powered on, the turntable 8 connected to the output end is rotated. The turntable 8 controls the rotation of the protrusion 9 connected to the side. The protrusion 9 slides within the adjusting plate 5. When the protrusion 9 rotates to the forward position, the adjusting plate 5 can be moved to drive the feed pipe 2 to rotate clockwise. When the protrusion 9 rotates to the rear position, the adjusting plate 5 can be moved to drive the feed pipe 2 to rotate counterclockwise. This causes the first mounting plate 13, the first connecting frame 14, the connecting rod 15, and the second connecting frame 16 to rotate back and forth. The copper wire in the limiting position dynamically contacts the electrolyte, and the stirring rod 21 agitates the electrolyte, making the tin ions in the electrolyte evenly distributed. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
