Description

Technical Field

[0001] The present invention relates to a flexible light strip auxiliary welding system, and in particular to an adjustable flexible light strip welding system. Background Art

[0002] The lighting industry is developing rapidly. Flexible light strips, with their innovative and practical value, are widely used in various applications, including living rooms, bedrooms, and kitchens, commercial windows, promotional areas, and automotive interiors. These applications meet diverse lighting needs, leading to rapidly growing market demand. However, traditional flexible light strip welding technology is plagued by numerous challenges. Manual welding, which predominates in production due to the tiny solder joints and thin metal conductors, requires extremely high worker skill. This can easily lead to fatigue errors, resulting in cold solder joints, short circuits, and high scrap rates, impacting production efficiency and quality. Even some companies employ semi-automatic welding equipment, but these equipment lacks adaptive adjustment capabilities due to differences in specifications such as wire spacing and width between different light strip models. The varying spacing between the metal conductors in each strip leads to high debugging costs when switching between production tasks, hindering companies' demand for efficient and cost-effective production. As the lighting industry moves towards intelligent and customized solutions, and consumers demand personalized lighting solutions, flexible light strip manufacturers face the need for frequent product adjustments. This demands welding systems that can quickly and accurately adjust parameters to accommodate a wide range of light strips, ensuring quality while improving efficiency.
