[0017] (III) Beneficial Effects

[0018] This utility model provides a device for silver-tin plating of wires, which has the following beneficial effects:

[0019] 1. This wire silver-tin plating device, through the coordinated arrangement of a heating element, a heating plate, a wire pressing assembly, and a sizing assembly, enables precise control of the silver-tin plating layer thickness. By placing heated molten silver-tin in the heating plate and using the wire pressing and sizing assemblies to press and sizing the wire, a more uniform silver-tin layer is achieved on the outer surface of the wire. Specifically, the wire pressing assembly ensures the wire is fully immersed in the molten silver-tin, resulting in uniform adhesion of the molten silver-tin to the outer wall of the wire; while the sizing assembly scrapes the outer surface of the wire to prevent localized areas of excessively thick or thin silver-tin layers, thus ensuring the uniformity of the wire diameter after silver-tin plating. This improvement effectively solves the problem of uneven tin plating layer thickness in existing technologies, improves the conductivity and corrosion resistance of the wire, and enhances the product's market competitiveness.

[0020] 2. This wire silver-tin plating device, through the design of its fluxing components, provides excellent fluxing functionality. By placing flux in the flux box and passing the wire sequentially through the flux box, below the wire clamping assembly, and the sizing assembly, flux adheres to the outer wall of the wire as it passes through the flux box. This effectively removes the oxide film on the outer surface of the wire during the silver-tin plating process, reduces the surface tension of the solder, promotes wetting, and prevents secondary oxidation during welding. This design significantly improves the quality and reliability of the silver-tin plating, avoids incomplete or insufficient plating on the outer surface of the wire, effectively solves the problem of poor fluxing effect in existing technologies, and enhances the conductivity and connection stability of the wire.

[0021] 3. This wire silver-tin plating device, through the coordinated arrangement of thermocouples, a control board, and heating elements, effectively controls the temperature of the heating plate, ensuring it remains at an optimal temperature and that the molten silver-tin within is in a state of optimal adhesion, thus enhancing the adhesion effect during wire silver-tin plating. More precise temperature control of the silver-tin liquid prevents uneven thickness of the silver-tin plating layer, thereby improving the quality of the wire. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0032] Please see Figures 1 to 6 The present invention provides a technical solution: a wire silver-tin plating device, comprising at least one wire 18 and a heating element. The wire silver-tin plating device also includes a control board, a first support plate 1, a second support plate 2, a housing, a soldering component, and a silver-tin plating component. The first support plate 1 and the second support plate 2 are arranged longitudinally parallel and are fixedly installed. The first support plate 1 and the second support plate 2 form a heating cavity. The heating element is installed in the heating cavity. The control board is electrically connected to the heating element.

[0033] The first support plate 1 and the second support plate 2 together form a support structure. The heating element uses currently available electric heating equipment, including but not limited to high-frequency induction furnaces and resistance furnaces. The heating element generates heat; its specific structure and principle will not be elaborated further. The conductor 18 refers to a single-strand conductive metal wire or metal wire. In this technical solution, the conductor 18 specifically refers to a 99.99% pure oxygen-free copper rod as the main raw material, drawn into the corresponding model wire by an intelligent copper drawing machine. After the conductor wire (i.e., conductor 18) is drawn, it enters the silver-tin plating stage. This involves plating a silver-tin alloy layer onto the conductor 18 using this wire silver-tin plating device, increasing the conductor's corrosion resistance. Furthermore, the conductivity of silver and tin is far higher than that of copper, so the conductivity of the conductor 18 after silver-tin plating is much higher than that of ordinary wires. The flux component is used to adhere flux to the outer surface of the conductor 18. The silver-tin plating component is used to silver-tin plating the conductor 18 after the flux has been adhered.

[0034] The flux component is fixedly installed at one end of the first support plate 1. The flux component includes a flux box 16, which contains flux.

[0035] The silver-tin plating component includes a heating plate 19, a wire pressing assembly, and a sizing assembly. The heating plate 19 is fixedly mounted on the first support plate 1, and the bottom wall of the heating plate 19 penetrates through the first support plate 1. The heat output end of the heating element abuts against the lower surface of the heating plate 19. The heating plate 19 contains molten silver-tin after heating. The wire pressing assembly and the sizing assembly are both installed inside the heating plate 19, with the wire pressing assembly located near the side where the flux box 16 is located.

[0036] The conductor 18 passes sequentially through the flux box 16, below the wire crimping assembly, and the sizing assembly. Flux adheres to the outer wall of the conductor 18 as it passes through the flux box 16. Molten silver-tin adheres to the outer wall of the conductor 18 as it passes below the wire crimping assembly. After the outer surface of the conductor 18 is adhered to the molten silver-tin, it passes through the sizing assembly.

[0037] The flux used includes, but is not limited to, solder paste or liquid flux (such as rosin solution, no-clean flux, etc.). The flux functions to: remove the oxide film from the outer surface of the conductor 18; reduce the surface tension of the solder and promote wetting; and prevent secondary oxidation during soldering. The heating plate 19 holds the silver-tin raw material or molten silver-tin. The heating element heats the heating plate 19, causing the silver-tin within it to become molten. The wire pressing assembly presses the conductor 18, immersing it in the molten silver-tin within the heating plate 19. After passing through the molten silver-tin, a layer of molten silver-tin adheres to the outer surface of the conductor 18. The sizing assembly scrapes the outer surface of the conductor 18 to prevent excessively thick or thin layers of molten silver-tin plating, ensuring a more uniform silver-tin layer and a more uniform wire diameter after plating.

[0038] Specifically, the flux component also includes a tripod 14 and an adjusting plate 15. The tripod 14 is fixedly installed at one end of the first support plate 1, and the adjusting plate 15 is adjustablely installed on the tripod 14 by multiple bolts. The flux box 16 is placed on the adjusting plate 15, and at least one limiting hole 17 is provided on the side wall of the flux box 16, through which the wire 18 passes.

[0039] The tripod 14 supports and fixes the adjusting plate 15. The adjusting plate 15 is movably mounted on the tripod 14 via multiple bolts. In practice, the height of the adjusting plate 15 can be adjusted by adjusting the height of the bolts to meet height adjustment needs. The adjusting plate 15 supports the flux box 16, which holds the flux. The limiting hole 17 on the flux box 16 guides the wire 18, limiting its position and preventing it from shaking. In practice, a towel is placed inside the flux box 16 and draped over the wire 18. The towel is soaked in flux inside the flux box 16, and when the wire 18 passes over the towel, its outer surface is coated with flux. For implementation, refer to... Figure 1 The conductor 18 is in a pulled state and can move along the long plating direction, that is, the conductor 18 can move through the soldering box 16 and the silver-plated tin component.

[0040] Specifically, the sidewall of the heating plate 19 protrudes inward to form an intermediate step 1901, and both the wire pressing assembly and the sizing assembly are mounted on the intermediate step 1901 of the heating plate 19. The wire pressing assembly includes a mounting plate 21, two first adjusting bolts 23, a first crossbar 24, at least one stop bar 25, and at least one wire pressing ring 26. The mounting plate 21 is fixedly mounted on the intermediate step 1901 of the heating plate 19. The two first adjusting bolts 23 are rotatably mounted on the two ends of the mounting plate 21, and the two ends of the first crossbar 24 are threadedly mounted to the two first adjusting bolts 23. When the two first adjusting bolts 23 rotate synchronously, they drive the first crossbar 24 to move up or down. The stop bar 25 is engaged with the first crossbar 24, and the lower end of the stop bar 25 passes through the mounting plate 21 and the two are slidably connected. The wire pressing ring 26 is fixedly mounted on the lower end of the stop bar 25, and the wire 18 passes under the wire pressing ring 26.

[0041] More specifically, the pressure plate assembly also includes two first fixing plates 20. Both first fixing plates 20 are fixedly mounted on the middle step 1901 of the heating plate 19. The mounting plate 21 is fixedly mounted to the two first fixing plates 20. The two first fixing plates 20 support and fix the mounting plate 21.

[0042] More specifically, both ends of the first crossbar 24 are fixedly connected to the first lifting plate 22, and the first adjusting bolt 23 passes through the first lifting plate 22 and the two are threadedly connected.

[0043] The inner bottom cavity of the heating plate 19 forms a liquid storage chamber 1902, used to hold silver-tin raw materials or molten metal. Two first adjusting bolts 23 are used to drive the first crossbar 24 to move up or down by synchronous rotation. When the first adjusting bolts 23 rotate, they push the first lifting plate 22 to rise or fall, and the first lifting plate 22 drives the first crossbar 24 to rise or fall, thereby adjusting the height position of the first crossbar 24. The first crossbar 24 drives the stop bar 25 to rise or fall, and the stop bar 25 drives the pressure ring 26 to rise or fall, thereby adjusting the height position of the pressure ring 26, that is, adjusting the depth of the pressure ring 26 in the heating plate 19, so that the pressure ring 26 can adapt to the liquid level of the silver-tin molten metal. Because as the silver-tin molten metal continuously adheres to the outer surface of the wire 18, the liquid level in the heating plate 19 will decrease. By adjusting the height of the pressure ring 26, the pressure ring 26 can always be submerged in the silver-tin molten metal, so that the wire 18 can always pass through the silver-tin molten metal.

[0044] More specifically, a thermocouple 27 is fixedly installed on the mounting plate 21. The heat sensing end of the thermocouple 27 is located at the inner bottom of the heating plate 19. The thermocouple 27 is electrically connected to the control board.

[0045] The mounting plate 21 supports the thermocouple 27, which is used to detect the temperature of the molten silver-tin mixture. The control board includes, but is not limited to, a microcontroller or a programmable logic controller (PLC). The control board contains logic control programs and timing control programs to meet the electrical control connection requirements of the thermocouple 27 and the heating element, to meet the control requirements of the heating element, and to meet the adjustment requirements of the heating element's control parameters. The control principle and structure of the control board will not be elaborated further. The thermocouple 27 detects the temperature of the molten silver-tin mixture and transmits relevant data parameters to the control board. The control board responds to the thermocouple 27 and controls the heating element to adjust the heating temperature.

[0046] More specifically, the sizing assembly includes a second crossbar 28 and at least one sizing ring 29. The second crossbar 28 is mounted on the intermediate step 1901 of the heating plate 19, and the sizing ring 29 is fixedly mounted on the second crossbar 28. The wire 18 passes through the central hole of the sizing ring 29.

[0047] The second crossbar 28 is used to support and fix the sizing ring 29. The wire 18 passes through the central hole of the sizing ring 29 in a taut state, with the central axis of the wire 18 located at the center of the central hole of the sizing ring 29. The sizing ring 29 is used to scrape the outer surface of the wire 18, preventing excessively thick or thin local silver-tin plating on the outer surface of the wire 18, thus making the silver-tin layer on the wire 18 more uniform and resulting in a more uniform wire diameter after silver plating.

[0048] More specifically, the sizing assembly also includes two second fixed plates 30, two second lifting plates 31, and two second adjusting bolts 32. The two second fixed plates 30 are fixedly mounted on the intermediate step 1901 of the heating plate 19. The two second adjusting bolts 32 are rotatably mounted on the two second fixed plates 30 respectively. The two second lifting plates 31 are respectively fitted onto the two second adjusting bolts 32, and the second adjusting bolts 32 are threadedly connected to the second lifting plates 31. Both ends of the second crossbar 28 are fixedly mounted to the two second lifting plates 31.

[0049] The second fixed plate 30 is used to support the second adjusting bolt 32. When the two second adjusting bolts 32 rotate synchronously, they drive the two second lifting plates 31 to rise or fall synchronously, thereby adjusting the height position of the two second lifting plates 31. The two second lifting plates 31 drive the second crossbar 28 to rise or fall, and the second crossbar 28 drives the two sizing rings 29 to rise or fall, thereby achieving the purpose of adjusting the height position of the sizing rings 29.

[0050] Specifically, the enclosure is fixedly mounted on the first support plate 1. An inlet 10 is provided on one side wall of the enclosure, and an outlet 12 is provided on the other side wall. Multiple support legs 4 are fixedly mounted below the second support plate 2, and a control box 13 is fixedly mounted on one end of the second support plate 2, with the control board installed inside the control box 13. Side baffles 3 are mounted on the first support plate 1 and the second support plate 2.

[0051] The enclosure serves to cover the silver-plated tin components, preventing accidental contact by workers and ensuring production safety. It also prevents external dust from entering the heating plate 19 and contaminating the molten silver-tin. Each support leg 4 supports the second support plate 2. The control box 13 houses the control board, the main control switch for the heating elements, and other components, ensuring electrical safety. The control box 13 may include, but is not limited to, a distribution box.

[0052] More specifically, the enclosure includes a support frame 8, a top cover 6, and two doors 5. The support frame 8 is fixedly mounted on a first support plate 1, and the two doors 5 are hinged to both sides of the support frame 8. A first side plate 9 and a second side plate 11 are fixedly mounted on the other two sides of the support frame 8, respectively. An inlet 10 is located on the first side plate 9, and an outlet 12 is located on the second side plate 11. An exhaust pipe 7 is fixedly mounted on the top cover 6, and the lower end of the exhaust pipe 7 penetrates the top cover 6.

[0053] The enclosure door 5 allows staff to easily observe the heating plate 19 after opening it, and also facilitates maintenance. The wire 18 passes through the soldering component, enters the enclosure through the inlet 10, passes through the silver-plated tin component, and exits through the outlet 12. The top cover 6 has an upward-convex dome structure, which facilitates the upward movement of fumes generated during the heating process of the silver-plated tin. These fumes are then discharged through the exhaust pipe 7 (the discharged fumes are not directly vented, but are introduced into an air purification device for purification before being vented; details will not be elaborated here).

[0054] The "silver-tin plating" in this technical solution does not simply refer to plating a layer of silver-tin alloy on the outer surface of the conductor 18; rather, it refers to plating a layer of molten metal on the outer surface of the metal conductor 18, which, after solidification, together with the metal conductor 18, forms a conductive conductor structure.

[0055] In operation, the operator first passes the wire 18 through the limiting hole 17 of the flux box 16 to ensure that the wire 18 is evenly covered with flux within the flux box 16. Then, the wire 18 enters the heating plate 19, passing sequentially through the pressure ring 26 and the sizing ring 29. By adjusting the first adjusting bolt 23 and the second adjusting bolt 32, the heights of the pressure ring 26 and the sizing ring 29 are adjusted to accommodate wires 18 of different specifications and to ensure their immersion depth and plating thickness in the molten silver-tin. Thermocouple 27 monitors the temperature of the molten silver-tin in real time and feeds the data back to the control board. The control board automatically adjusts the power of the heating element (no specific power limit is defined here) according to preset temperature parameters (temperature parameters, etc., are not specifically defined or limited in this technical solution; due to seasonal factors, room temperature is not constant, and the control temperature values ​​of the control board are also adjustable accordingly) to ensure the stability of the molten metal temperature. The entire device operates under the protection of the enclosure to ensure operational safety and prevent external contamination. The exhaust pipe 7 continuously discharges the flue gas generated during the heating process, keeping the working environment clean.
