Description

Technical Field

[0001] This utility model relates to the technical field of copper wire surface processing equipment, and more specifically, to a copper wire hot-dip tinning machine. Background Technology

[0002] Hot-dip tinning of copper wire is a surface treatment process that involves immersing cleaned copper wire in molten tin at high temperatures to create a uniform tin layer on the wire surface. This process effectively prevents oxidation and corrosion of the copper wire, improves solderability and conductivity, and reduces the surface friction coefficient. Hot-dip tinned copper wire combines the conductivity of copper with the corrosion resistance of tin, making it widely used in electronic components, cable manufacturing, and precision instrument wires.

[0003] In the hot-dip tin plating process for copper wire, the uniformity of the plating thickness and the utilization rate of tin are key factors affecting product quality and production costs. In traditional copper wire tin plating processes, the control of plating thickness often relies on manual experience, which can easily lead to uneven plating and large thickness fluctuations, affecting product quality. In addition, excess tin during the plating process is often wasted because it cannot be effectively recycled, increasing production costs. At the same time, switching between different specifications of copper wire usually requires manual adjustment of equipment parameters, resulting in low production efficiency. Utility Model Content

[0017] 3. Beneficial effects

[0018] Compared with the prior art, this utility model provides a copper wire hot-dip tinning machine, which has the following beneficial effects:

[0019] (1) The copper wire hot-dip tinning machine, according to the diameter of the circular cross-section of the copper wire, controls the rotation of the transmission worm gear, which drives the corresponding synchronous gear to rotate. Another synchronous gear drives the circular multi-hole scraper to rotate at a fixed angle, so that the scraping hole corresponding to the size of the copper wire is at the lowest position. Then, by controlling the start of the electric telescopic rod, the T-shaped plate is raised or lowered, thereby adjusting the height of the circular multi-hole scraper, so that the center of the circular cross-section of the copper wire after tinning coincides with the center of the corresponding circular scraping hole. After the copper wire passes through the scraping hole, the excess tin liquid on the surface of the copper wire will be scraped off, realizing precise control of the coating thickness during the copper wire tinning process, ensuring the uniformity of the coating on the surface of the copper wire, improving the production quality of copper wire hot-dip tinning. The scraped tin liquid will fall into the interior of the tinning box, significantly reducing tin waste and saving production costs.

By controlling the start of the hydraulic cylinder, the support frame can be moved up and down inside the tinning box, thereby adjusting the height of the two round rollers and thus realizing the immersion depth of the copper wire in the tin liquid. At the same time, the tension of the copper wire can be controlled to avoid the copper wire from shaking, and prevent the copper wire from shaking from affecting the tinning and subsequent surface treatment.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] Example:

[0030] Please see Figures 1-5 A copper wire hot-dip tinning machine, comprising:

[0031] Tin plating box 1;

[0032] Adjustable floating roller mechanism 2, which is fixedly installed on the top of tin plating box 1; and

[0033] An electric telescopic rod 3 is fixedly installed on the top of the tin-plating box 1. A T-shaped plate 4 is fixedly connected to the output end of the electric telescopic rod 3. A control box 8 is fixedly connected to one outer surface of the T-shaped plate 4. A transmission worm gear 11 is rotatably connected between the control box 8 and the T-shaped plate 4. A transmission worm 10 is rotatably connected between the inner walls of both sides of the control box 8. A circular perforated scraper 5 is rotatably connected to one outer surface of the T-shaped plate 4. Two synchronous gears 12 are rotatably connected to the other outer surface of the T-shaped plate 4. One synchronous gear 12 is fixedly connected to the transmission worm gear 11, and the other synchronous gear 12 is fixedly connected to the circular perforated scraper 5.

[0034] In a specific embodiment of this utility model, two fixed rollers are installed on the top of the tin plating box 1. Copper wire is fed in from one fixed roller, passes through the adjustable floating roller mechanism 2, and then exits via the other fixed roller. It then passes through a circular perforated scraper 5. The circular perforated scraper 5 has circular scraping holes of various diameters. According to the diameter of the circular cross-section of the copper wire, the transmission worm gear 10 is controlled to rotate, which drives the transmission worm wheel 11 to rotate. The transmission worm wheel 11 drives the corresponding synchronous gear 12 to rotate. The two synchronous gears 12 are connected by a synchronous belt. The other synchronous gear 12 drives the circular perforated scraper 5 to rotate at a fixed angle, so that the scraping hole corresponding to the size of the copper wire is located at... The device is positioned at its lowest point. Then, by controlling the electric telescopic rod 3, the T-shaped plate 4 is raised or lowered, thereby adjusting the height of the circular multi-hole scraper 5. This ensures that the center of the circular cross-section of the copper wire after tin plating coincides with the center of the corresponding circular scraping hole. After the copper wire passes through the scraping hole, excess tin liquid on the surface of the copper wire is scraped off, achieving precise control of the plating thickness during the copper wire tin plating process. This ensures the uniformity of the plating layer on the surface of the copper wire and improves the production quality of hot-dip tin plating. The scraped tin liquid falls into the interior of the tin plating box 1, significantly reducing tin waste and saving production costs. At the same time, through automated mechanical transmission, it can adapt to the rapid switching of multiple specifications of copper wire, improving production efficiency.

[0035] Specifically, the top of the tin-plating box 1 is fixedly connected to a limiting rod 6, and the T-shaped plate 4 is slidably sleeved on the limiting rod 6.

[0036] In this embodiment, the limiting rod 6 ensures that the T-shaped plate 4 remains stable in the horizontal direction when adjusting its height.

[0037] Specifically, a servo motor 9 is fixedly installed on one outer surface of the control box 8, and the output end of the servo motor 9 is fixedly connected to the transmission worm gear 10.

[0038] In this embodiment, by controlling the servo motor 9 to start, the transmission worm gear 10 can be driven to rotate.

[0039] Specifically, a protective box 7 is fixedly connected to the outer surface of the other side of the T-shaped plate 4, and two synchronous gears 12 are rotatably connected between the protective box 7 and the T-shaped plate 4.

[0040] In this embodiment, the protective box 7 protects the two synchronous gears 12 from being exposed.

[0041] Specifically, the adjustable floating roller mechanism 2 includes a support frame 201, a hydraulic cylinder 202, a support frame 203, and two circular rollers 204. The support frame 201 is fixedly connected to the top of the tin plating box 1, the hydraulic cylinder 202 is fixedly installed on the top of the support frame 201, and the output end of the hydraulic cylinder 202 extends into the interior of the tin plating box 1. The support frame 203 is fixedly connected to the output end of the hydraulic cylinder 202, and the two circular rollers 204 are rotatably connected between the inner walls of the two sides of the support frame 203.

[0042] In this embodiment, when the copper wire moves inside the tin plating box 1, it is pressed into the molten tin by two rollers 204. By controlling the hydraulic cylinder 202 to start, the support frame 203 can be moved up and down inside the tin plating box 1, thereby adjusting the height of the two rollers 204, thus realizing the immersion depth of the copper wire in the molten tin. At the same time, the tension of the copper wire can be controlled to avoid the copper wire from shaking, and to prevent the copper wire from shaking from affecting the tin plating and subsequent surface treatment.

[0043] Specifically, the adjustable floating roller mechanism 2 also includes two stabilizing rods 205, both of which are fixedly connected to the top of the support frame 203, and the two stabilizing rods 205 slide through the top of the support frame 201.

[0044] In this embodiment, two stabilizing rods 205 are used to ensure that the support frame 203 remains stable during vertical movement.

[0045] Working principle: Copper wire is fed in from a fixed roller, passes through two circular rollers 204, and then exits via another fixed roller. The hydraulic cylinder 202 is activated, causing the support frame 203 to move up and down inside the tin plating box 1, thereby adjusting the height of the two circular rollers 204 and thus controlling the immersion depth of the copper wire in the molten tin. Simultaneously, the tension of the copper wire is controlled to prevent vibration, which could affect tin plating and subsequent surface treatment. Based on the diameter of the copper wire's circular cross-section, the servo motor 9 is activated, driving the transmission worm gear 10 to rotate, which in turn drives the transmission worm wheel 11. The transmission worm wheel 11 drives the corresponding synchronous gear 12. The two synchronous gears 12 are connected by a synchronous belt. The other synchronous gear 12 drives the circular multi-hole... The scraper 5 rotates to a fixed angle, so that the scraping hole corresponding to the copper wire size is at its lowest position. Then, the electric telescopic rod 3 is activated, driving the T-shaped plate 4 to rise or fall, thereby adjusting the height of the circular multi-hole scraper 5. This ensures that the center of the circular cross-section of the copper wire after tinning coincides with the center of the corresponding circular scraping hole. After the copper wire passes through the scraping hole, excess molten tin on the surface of the copper wire is scraped off, achieving precise control of the plating thickness during the copper wire tinning process. This ensures the uniformity of the plating layer on the surface of the copper wire and improves the production quality of hot-dip tinning. The scraped molten tin falls into the interior of the tinning box 1, significantly reducing tin waste and saving production costs. At the same time, through automated mechanical transmission, it can adapt to the rapid switching of multiple specifications of copper wire, improving production efficiency.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
