[0002] Solder ribbon is a metal strip commonly used in electronic soldering processes. It has a specific width and thickness and is coated with the solder required for soldering. The primary function of solder ribbon is to form an electrical connection between electronic components, ensuring smooth current transmission. A solder ribbon typically consists of a conductive material and a layer of solder covering it. The conductive material provides good electrical conductivity, while the solder layer melts during the soldering process, filling the gaps between electronic components and forming a secure solder joint. Existing solder ribbons are typically stored in a coiled form, making it impossible to adjust the ribbon's delivery position during the supply process. Furthermore, the tension of the solder ribbon cannot be adjusted during transport, resulting in excessive tension and damage.

[0003] To address the shortcomings of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a circular photovoltaic welding ribbon winding device [201810832418.7], which includes a frame, a conversion device, a large turntable, a small turntable, a cutter, a first bracket, and a wire pressing device. The large turntable is rotatably mounted on the frame, a wire clamping block is provided on the side wall of the small turntable, two small turntables are provided, and are rotatably mounted on the large turntable.
