FSPR robotic system: The best way to solve the riveting problems of automotive roof component
I. Background Introduction
In the past two years, the automotive industry has encountered significant challenges when dealing with the riveting process of a new car roof component. This new roof component is composed of multiple layers of differently shaped workpieces (dual-phase steel - cast aluminum - dual-phase steel), with adhesive used between the layers. The industry's traditional SPR process has shown numerous issues in practical operations, including easy cracking of cast aluminum workpieces at the seams, difficulty in pre-drilling holes in the workpieces, and difficulty in aligning holes on multiple layers of plates. These problems have led to high costs and low efficiency in the connection process, making it impossible to achieve reliable connections.
II. Product and Technical Solution
In response to the above challenges, we have introduced the FSPR Robotic Riveting Gun System as a solution. The FSPR technology, with its unique advantages, can effectively achieve riveting of two or more layers of materials (such as steel, aluminum, cast aluminum, high-strength steel, aluminum alloy, carbon fiber, etc.).
Servo Cylinder Application： We use a servo cylinder (8 tons) as the actuator to output high-tonnage riveting force and precisely control the riveting process. The use of this cylinder ensures stability and accuracy during riveting, reducing issues such as workpiece cracking caused by insufficient or unstable riveting force.
Real-time Monitoring and Data Analysis： To gain real-time understanding of the force and displacement changes during the riveting process, we have utilized a newly developed riveting monitor (HRC670). This monitor can record and store the force and displacement curves during the riveting process in real-time for subsequent inspection and analysis. This not only improves the traceability of the process but also provides strong support for continuous improvement.
III. Technical Impact and Application Effects
Solving Industry Technical Challenges： The successful application of the FSPR Robotic Riveting Gun System has solved the industry's technical challenge of ineffective connections between difficult-to-weld materials such as hot-formed steel and cast aluminum. It provides a new technical means for achieving reliable connections between various difficult-to-weld materials.
Lightweighting of Automotive Bodies： With the continuous development of the automotive manufacturing industry, lightweighting has become key to reducing the chemical energy consumption of vehicles during use. The application of the FSPR Robotic Riveting Gun System not only improves the reliability of riveted connections but also contributes to the lightweighting of automotive bodies, further enhancing the energy efficiency of vehicles.
With its efficient and stable riveting performance and precise real-time monitoring capabilities, the FSPR Robotic Riveting Gun System has successfully addressed the challenges faced by automakers in the riveting process of new car roof components. Its emergence has not only driven technological progress in the automotive manufacturing industry but also brought broader development space and market competitiveness to automakers.
