Description

Technical Field

[0001] This utility model relates to the field of wire processing technology, and in particular to a wire tin-plated extension and transmission device. Background Technology

[0002] In continuous tin plating of wire, the wire is annealed and cleaned before being immersed in a tin bath, and then drawn to a cooling and setting zone to solidify the plating and achieve finished product. Currently, most equipment has a fixed transmission distance between the tin bath and the cooling zone, and the transmission speed and dwell position are difficult to adjust online. This results in the inability to flexibly optimize the immersion depth, immersion speed, and cooling start position according to the wire diameter, material, or production speed. As a result, defects such as uneven tin layer thickness, drips, bridging, skinning, or reflow often occur. Poor control of cooling speed and thermal stress can also easily cause cracks, decreased adhesion, and surface oxidation, reducing product yield and increasing rework and scrap rates. In addition, the fixed stroke is not conducive to rapid changeover and production cycle adjustment, affecting equipment versatility and production efficiency. Therefore, it is necessary to improve the transmission and cooling layout to make the output stroke, position, and speed adjustable, so as to achieve precise control of the cooling and setting process, improve plating uniformity and yield, and meet the flexible production needs of multi-specification wires. Utility Model Content

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-4As shown, in one embodiment of this utility model, a wire tinning extension and transmission device is disclosed, comprising a frame 1, a tin furnace 2, a tin-immersed wire assembly 3, an extension transmission component 4, an output wire assembly 5, and a cooling component 6. The tin furnace 2 is mounted on the frame 1, and the tin-immersed wire assembly 3 is positioned above the tin furnace 2 and is equipped with a tin-immersed wire support 7. One end of the tin-immersed wire support 7 extends into the tin furnace 2 for guiding the wire toward the output wire assembly 5. The extension transmission component 4 is located above the tin-immersed wire assembly 3, and the output wire assembly 5 is mounted on the extension transmission component 4. The extension transmission component 4 drives the output wire assembly 5 to move relative to the tin furnace 2 to adjust the distance between the output wire assembly 5 and the tin-immersed wire assembly 3. The cooling component 6 is located on both sides of the extension transmission component 4 for cooling the wire during the transmission process. This embodiment significantly improves the stability and production capacity of the wire tinning process by coordinating the tin-immersed guidance, adjustable extension transmission, and dual-sided cooling. The tin-immersion lead frame 7 precisely guides the wire into the tin bath 2, ensuring consistent entry angle and position, thus reducing defects such as splashing, uneven tinning, and wire scratches from the source. The extended transmission assembly 4 drives the output lead assembly 5 to move relative to the tin bath 2, precisely adjusting the distance between the output and tin-immersion lead, thereby flexibly controlling the immersion depth and residence time of the wire in the molten tin. This adapts to wires of different diameters and speeds, improving plating uniformity and thickness controllability, and facilitating online parameter optimization and shortening debugging time. Cooling components 6 are arranged on both sides of the extended transmission assembly 4 to achieve rapid and symmetrical cooling of the passing wire, promoting rapid tin solidification, reducing oxidation, tin dripping, and deformation, and stabilizing surface finish and adhesion. The overall structure is compact and has a fast adjustment response, not only improving yield and production efficiency, reducing material waste and rework rates, but also facilitating maintenance and process expansion, demonstrating significant industrial application value.

[0020] A workbench 11 is provided on the upper surface of the frame 1, and the solder pot 2 is placed on the workbench 11, with the solder pot 2 sinking towards the workbench 11; a heating tube 21 is provided inside the solder pot 2 for heating the solder. In this embodiment, placing the solder pot 2 on the workbench 11 above the frame 1 and sinking it towards the workbench 11, and equipping it with a heating tube 21, can bring about multiple technical benefits. The workbench 11 provides stable and reliable positioning for the tin furnace 2, facilitating precise alignment with the tin-immersion wire support 7 and the extended transmission assembly 4, and reducing the impact of operational vibration on the uniformity of the plating layer. The sunken design of the tin furnace 2 reduces the exposed height of the molten tin and the surrounding splash and heat dissipation area, thereby reducing oxidation and heat loss, improving operational safety, and facilitating operator protection and cleaning. The heating tube 21 inside the furnace directly heats the molten tin, providing rapid heating and precise temperature control, maintaining a stable temperature distribution and suitable viscosity for the molten tin, ensuring consistent plating adhesion and thickness, while reducing energy consumption and shortening preheating time. The overall layout also facilitates collaborative work with the cooling assembly 6 and the extended transmission mechanism, improving production stability, yield, and ease of maintenance.

[0021] The tin-immersion wire assembly 3 includes a fixed bracket 31, on which tin-immersion wire supports 7 are mounted. The fixed bracket 31 includes a fixing element 32 and a crossbeam 33. Multiple tin-immersion wire supports 7 are arranged in a linear array on the crossbeam 33 and are located above the tin furnace 2. Specifically, the fixing element 32 includes a fixing base 321 and a fixing rod 322. The fixing base 321 is provided with a groove 323, and the fixing rod 322 is disposed on the groove 323. The groove 323 extends along the length direction of the tin furnace 2, and the fixing rod 322 adjusts the position of the crossbeam 33 along the length direction of the groove 323. In this embodiment, the linear array ensures parallel and equidistant guidance of multiple or continuous wires, stabilizes the feeding direction and tension, reduces scratches and uneven tinning, and improves plating consistency and yield. Secondly, the groove 323 on the fixed base 321 and the fixed connecting rod 322 that can slide along the groove allow the position of the crossbeam 33 to be precisely adjusted along the length of the tin furnace 2. The bracket arrangement can be quickly changed without disassembly to adapt to the needs of different diameters, spacings or process sections, improving equipment adaptability and changeover efficiency. In addition, the adjustable structure facilitates alignment and calibration, and together with the extended transmission component 4, it achieves precise control of immersion depth and dwell position, further optimizing tinning thickness and surface quality. The modular bracket also facilitates cleaning, maintenance and replacement, reducing downtime and extending equipment life.

[0022] The tin-dipping conductor support 7 includes a tin-dipping guide rod 71, a tin-dipping fixing block 72, and a tin-dipping guide wheel 73. The tin-dipping guide rod 71 is movably mounted on a crossbeam 33, and screws are provided on the crossbeam 33 to fix the tin-dipping guide rod 71. The tin-dipping fixing block 72 is located at one end of the tin-dipping guide rod 71, and the tin-dipping guide wheel 73 is located on the tin-dipping fixing block 72 for guiding the wire toward the output conductor assembly 5. Specifically, the tin-dipping fixing block 72 is provided with a conductor groove 721, which is opposite to the tin-dipping guide wheel 73. In this embodiment, the tin-immersed wire support 7 is composed of a movable tin-immersed guide rod 71, a fixed position screw, a tin-immersed fixing block 72 at the end of the guide rod, and a guide wheel. This combination not only enables the support to be quickly positioned and firmly locked on the crossbeam 33, ensuring stable guiding position under tension and vibration conditions, and avoiding guide deviation and process instability; the tin-immersed guide wheel 73 is positioned opposite to the wire groove 721 on the fixing block, which can centrally constrain the wire and provide low-friction rolling support, reducing direct sliding friction, wear, and heat generation between the wire and the support, and reducing the risk of surface damage and plating defects; the groove and guide wheel cooperation facilitates adaptive positioning of wires of different diameters, making it easy to change specifications and quickly debug, improving equipment versatility and production changeover efficiency; the modular fixing structure facilitates maintenance and replacement of worn parts, reducing downtime.

[0023] The extended transmission assembly 4 includes a transmission fixing frame 41 and a transmission drive module 42. The transmission fixing frame 41 is mounted on the frame 1, and the transmission drive module 42 is mounted on the transmission fixing frame 41. The output wire assembly 5 is mounted on the transmission drive module 42, and the transmission drive module 42 is used to drive the output wire assembly 5 to move relative to the solder pot 2. Specifically, the transmission drive module 42 includes a transmission frame 421, a drive motor 422, a transmission chain assembly 423, and a transmission guide rail 424. The transmission frame 421 is mounted on the transmission fixing frame 41, the drive motor 422 is mounted on the transmission frame 421 and drivenly connected to the transmission chain assembly 423, and the output wire assembly 5 is slidably mounted on the transmission guide rail 424 and connected to the transmission chain assembly 423. The drive motor 422 is used to drive the transmission chain assembly 423 to drive the output wire assembly 5 to slide along the transmission guide rail 424. The output lead assembly 5 includes a lead drive seat 51 and an output lead wheel 52 disposed on the lead drive seat 51. The lead drive seat 51 is mounted on a transmission guide rail 424 and connected to a transmission chain assembly 423. In this embodiment, the drive motor 422 drives the output lead assembly 5 to move smoothly and controllably along the guide rail via the transmission chain assembly 423, thereby achieving precise control of the advance and retreat distance of the wire relative to the solder bath 2. This effectively ensures consistent tinning depth, high repeatability of plating thickness, and reduces molten solder disturbance and splashing caused by rapid advance and retreat. The output lead assembly 5 is slidably mounted on the transmission guide rail 424 and rigidly connected to the transmission chain assembly 423, ensuring synchronization and positioning accuracy during movement, reducing the impact of mechanical shock and vibration on wire tension and plating uniformity, and improving yield and process stability. The cooperation between the lead drive seat 51 and the output lead wheel 52 stabilizes the wire traction force, prevents slippage or twisting, and facilitates seamless changeover of wires of different diameters and materials through speed adjustment, demonstrating strong adaptability.

[0024] The cooling assembly 6 includes a mounting plate 61 and a cooling fan 62. The mounting plate 61 is disposed on both sides of the extended transmission assembly 4, and the cooling fan 62 is disposed on the mounting plate 61 and blows air to cool the wire during transmission. In this embodiment, the symmetrical arrangement on both sides can achieve uniform cooling of the wire, significantly accelerate the solidification rate of the tin layer, reduce tin melt backflow, sagging, or bridging defects, and improve the smoothness and density of the plating surface. The cooling curve can be adjusted by wind speed and direction, thereby precisely controlling the cooling rate and thermal stress distribution, reducing the risk of cracks and peeling, and ensuring the consistency of plating thickness and physical properties. Directional airflow can also reduce oxidation and oxide scale formation on the wire surface, and improve electrical and soldering performance. The cooling position is close to the extended output end, which can shorten the time window from the finished product to downstream processing, and improve production cycle and line speed. The modular design of the mounting plate 61 facilitates maintenance and fan replacement, and reduces downtime. When linked with temperature / speed closed-loop control, it can further optimize the yield rate and reduce energy consumption, and improve overall production stability and equipment utilization.
