A typical client is a company specializing in the design, production, and sales of children's bicycles, adult bicycles, and toy vehicles. In recent years, the company has been fully committed to advancing the intelligent upgrade of its production lines. Addressing the complex requirements for welding the intersecting lines of bicycle forks, we collaborated with partners to design an automated welding solution based on four collaborative robots. This solution has helped the client overcome critical challenges in welding bicycle fork components.
