In the automobile body structure, the wrapping skin is an important part covering the surface of the body frame, which affects the strength, durability and aerodynamic performance of the body to a certain extent. As a very important connection process in the field of automobile parts manufacturing, spot welding technology occupies a central position in the connection process between the skin and the body frame or other internal structural parts.

In recent years, automobile manufacturers are constantly looking for effective ways to reduce costs and increase efficiency, while also ensuring the reliability of product quality. In this context, the traditional manual skin connection process gradually shows its limitations, and it is difficult to meet the stringent requirements of modern automobile manufacturing industry for high efficiency, precision and stability, and automated production has become the key to break the ice.

Based on Wuhu's complete automobile industry cluster and parts industry chain, a domestic head automobile enterprise has set up a highly automated production line in Fuzhou base, with nearly 100 high-precision and high-efficiency robots, realizing an all-around automated production process from raw material welding to finished product inspection. Key lines such as the rear floor assembly line, left/right rear wheel cover assembly line and left/right side enclosure reinforcement plate have adopted the industry's top production equipment and technology, realizing the whole chain of automated production from raw materials to finished products. This efficient and precise production mode not only significantly improves the production efficiency, but also ensures the excellent stability and consistency of product quality.

On the intelligent production line in Fuzhou, there is a batch of Estun UNO220-2700 spot welding robots, which lead a new round of change in the field of auto parts manufacturing with its excellent performance and innovative technology. Estun UNO series spot welding robots adopt the perfect combination of high rigidity body and high performance motors, with the speed enhancement algorithm of full dynamics model, which realizes the significant improvement of the beat. This breakthrough design enables the UNO series robots to complete each weld point faster and more accurately when performing spot welding operations, thus dramatically increasing productivity.

UNO series robots have independently developed welding torch servo motors and realized the autonomy of the core electronic control. This innovation not only makes the UNO series robots perfectly matched with our add-on axis drives, but also compatible with all major brands of welding tongs, which can be used directly without on-site debugging. This feature greatly simplifies the installation and debugging process, shortens the time for the equipment to be put into production, and saves a lot of labor and material costs for customers.

In addition, the UNO series robots are designed with a balance of space utilization and performance optimization in mind. Compared to traditional general-purpose motors, the UNO series robots have 30% shorter motors, a maximum speed of 5,000+ rpm, and a maximum overload capacity of 300%. This outstanding performance allows the UNO series robots to maintain excellent stability and durability during high-intensity, high-frequency spot welding operations.

In the field of automotive parts manufacturing, the UNO series of robots provides a new solution for automotive manufacturers. It not only meets the stringent requirements of modern automotive manufacturing for high efficiency, precision and stability, but also provides customers with more flexible and customized services.

With the continuous development of the global automotive industry and the changing needs of consumers, Estun has continued to plumb the depths of the automotive industry, promoting intelligent manufacturing and industrial upgrading, bringing efficient and flexible production capacity to automotive manufacturing, and accelerating the transformation of the automotive industry to intelligence and automation.
