Description

Technical Field

[0001] This utility model relates to the technical field of wire harness tin plating equipment, specifically a wire harness tin plating device. Background Technology

[0002] Electronic wire harnesses generally refer to low-voltage electronic wire groups. They bridge the gap between two or more isolated electronic circuits, enabling current flow and allowing various electronic components to perform their functions. Copper wire is an important component of electronic wire harnesses, possessing excellent conductivity. However, copper wire exposed to air is prone to oxidation, forming verdigris, which reduces the conductivity of the electronic wire harness and may even increase resistance. Therefore, an automatic tinning machine is needed to tin-plate the surface of the copper wire. During tinning, a pressing roller is used to immerse the copper wire into a tin bath. In response, Chinese utility model patent CN218159788U discloses an automatic tin plating mechanism for electronic wire harnesses, including a base plate, a telescopic drive mechanism, a copper wire body, a pressing wheel, and a tin plating tank. A tin plating tank is located at one end of the top of the base plate, and a telescopic drive mechanism is mounted above the tin plating tank via a bracket. A lifting frame is mounted at the output end of the telescopic drive mechanism via a telescopic column, and a pressing wheel is located inside the lifting frame. A winding roller is located at the other end of the top of the base plate. The copper wire body passes through the pressing wheel and is wound onto the winding roller. This utility model, by installing a base plate, tin plating tank, bracket, telescopic drive mechanism, lifting frame, pressing wheel, and copper wire body, allows the pressing wheel to immerse the copper wire body in the molten tin for hot-dip tin plating. The telescopic drive mechanism can drive the lifting frame to rise and fall via a telescopic rod, facilitating adjustment of the pressing wheel's position as the molten tin level drops, ensuring the copper wire body is always immersed in the molten tin, thus guaranteeing the tin plating effect. The aforementioned equipment lacks a limiting structure for the wire harness during use, which may cause the wire harness to slip off the pulley during the tin plating process. Therefore, we propose a wire harness tin plating device to solve the above problem. Utility Model Content

Multiple heating rings 9 are evenly arranged inside the heating tank 102. The inner wall of the protective enclosure 10 is fixedly connected to the outer wall of the tin plating bath 1.

[0017] Furthermore, the width of the protective enclosure 10 is greater than the width of the heating tank 102.

[0018] Example 2: Please see Figure 3 and Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment; Specifically, the limiting component 7 includes two connecting plates 71, which are symmetrically fixed to the top surface of the tin plating bath 1. A fixing rod 72 is fixedly connected between the two connecting plates 71 at both ends. Multiple movable plates 73 are provided between the connecting plates 71. Each movable plate 73 has an adjustment hole 74, which engages with the fixing rod 72. An annular fixing groove 75 is provided on one side of each movable plate 73. A rotating bearing 76 is fixedly connected to the annular fixing groove 75. A rotating ring 77 is fixedly connected to the rotating bearing 76. An adjusting ring 78 is fixedly connected to the rotating bearing 76. The adjusting ring 78 is threadedly engaged with the fixing rod 72. Threaded joints are provided on the inner wall of the adjusting hole 74 and on the fixing rod 72, respectively. The components are interlocked. The movable plate 73 is provided with a limiting hole 79 corresponding to the fixed roller 601. The limiting hole 79 is surrounded and fixedly connected to the contact pad 710.

When the position of the wire harness needs to be adjusted, the adjusting ring 78 can be rotated under the action of the rotating bearing 76, so that it drives the moving plate 73 to move on the fixed rod 72 under the thread engagement with the fixed rod 72. The moving plate 73 is moved to adjust its position, thereby adjusting the distance between different wire harnesses, which facilitates the simultaneous tin plating of multiple sets of wire harnesses and avoids contact between multiple sets of wire harnesses.
