In the development trend of the automotive industry towards intelligent manufacturing, ESTUN, as a leading automation brand in China, relies on its core technologies of robotics and motion control and advanced digital products. Facing the market demand for high-quality and efficient production in the automotive industry, it has complete industry solutions, deep industry experience accumulation and innovation capabilities, helping automobile companies to achieve efficient, precise and flexible intelligent manufacturing.

With the continuous improvement of efficiency and flexibility requirements for intelligent production lines of commercial trucks, the demand for heavy-load, long-reach, and highly flexible industrial robots is increasing. Based on its autonomous core robot technology, ESTUN has launched a number of large-load robots that meet the needs of the automotive industry. Among them, ER220B-2650, ER220-2700, and ER350-3300, with the strong driving force of ESTUN servo systems, have industry-leading high rigidity and high precision advantages, and are equipped with mature spot welding process software, which perfectly meet the application scenarios of body-in-white welding lines.

The intelligent production line of commercial vehicle cabs is one of the top scenarios in the field of automotive industrial manufacturing. Each cab needs to complete 3,000-5,000 welding points, and more than 80% of the connection process is spot welding. Manual welding has problems such as low efficiency and consistency of weld quality. Taking full advantage of the robot's high stability, high speed and high precision collaborative work capabilities can greatly improve the flexibility and efficiency of the production line and create maximum value for customers.

Spot Welding

ESTUN has customized and developed the spot welding robots ER220B-2650, ER220-2700 and ER350-3300, which can meet the requirements of efficient, highly stable and highly intelligent white body spot welding scenarios.

Advantages and features

• Online load identification, self-learning vibration suppression, and scene adaptation debugging ensure the best performance of the robot

• Precise pressure control, pressure error can be controlled within ±2%

• Free choice of welding clamp opening and closing mode, high-performance dynamic model, improve spot welding efficiency

• Support mainstream communication methods: Profinet, EtherNet/IP, DeviceNet, CC-Link, etc.

• Dedicated spot welding process software improves debugging efficiency, adapts to multiple brands of welding controllers, supports tool switching, and can realize multi-process applications

• ESTUN's independent welding clamps better cooperate with customer selection and design to meet application scenarios.

Handling

The assembly and transmission of automobile body-in-white welding lines often involve parts handling scenarios. Manual handling of parts is inefficient and has poor human-machine and safety. ESTUN has customized and developed a variety of 220kg-700kg large-load robots to meet the application scenarios of automobile production line handling. Together with a motion control system with advanced algorithms and high-speed processing capabilities, it can achieve precise control of robots and equipment, ensure the perfect integration of robots and production lines, and meet the needs of production line automation and intelligence.

As a leading brand of Chinese robots, ESTUN Automation has a full range of 87 industrial robots, covering 3-700kg loads, including 18 main models in the automotive industry, providing the industry with rich case experience. In the future, ESTUN will work with partners to jointly promote the sustainable development of intelligent manufacturing!
