Automotive spot welding workstation

High-efficiency, Stability, Intelligent

In the field of automobile manufacturing, traditional spot welding operation is highly dependent on manual operation, which is not only labor-intensive, but also difficult to ensure the consistency of welding quality, especially in the complex curved surfaces and narrow space welding operations, but also puts forward very high requirements for workers' skills. With the accelerated replacement of automobile models, the production line needs to be frequently adjusted to meet the welding needs of different models, which greatly tests the flexibility and rapid response capability of the production line.

Facing the market demand of high quality and high efficiency production in the automotive industry, Estun has customized the development of UNO series of spot welding robots to meet the demand of high efficiency, stable and intelligent body spot welding scenarios with the advantages of high rigidity, high performance and high protection, helping automotive manufacturing to achieve a high level of welding, which can significantly improve the welding efficiency and product quality of the automotive industry.

1.Estun has custom-developed UNO220-2700, a dedicated spot welding robot, to meet the needs of efficient, stable and intelligent body-in-white spot welding scenarios.

3.Precise pressure control, pressure error can be controlled at ±2%. Welding clamp opening and closing methods are freely selectable, high-performance kinetic model to enhance spot welding efficiency.

4.Dedicated spot welding process software to enhance debugging efficiency, adaptable to multi-brand welding controllers, support for tool switching, can realize multi-process applications.

Laser Flight Welding Solutions

Creating Efficient Laser Flight Welding

With the booming development of the electric vehicle market, the demand for lithium batteries continues to grow, and the requirements for the production efficiency and quality of lithium batteries are getting higher and higher. Take Busbar as an example, as an important conductive connection component in lithium battery, its welding quality is directly related to the safety and performance stability of lithium battery. However, the traditional fixed-point welding method is characterized by low efficiency, unstable quality and other problems, making it difficult to meet the needs of large-scale production. Estun robotic automation welding solutions help the world's leading power battery manufacturers to solve the dilemmas of fixed-point welding, and improve production efficiency and welding quality.

Traditional Busbar welding, no matter how the process iteration, essentially need third-party vision or PLC initiative to initiate the position information, robot addressing, beat will always have a pause waiting for welding time, flight welding is a qualitative change in the process. Robot trajectory movement and scanning position of the vibration mirror real-time synchronization, through real-time visual inspection of the feedback for dynamic correction of the welding position, vibration mirror through the robot real-time trajectory as the basis, and vision data to compensate for the realization of the movement of non-stop welding.

Estun's robotic laser flight welding solution integrates high performance UNO series robot + BLACKBIRD control system + SCANLAB galvanometer module +KEYENCE vision system + IPG ring spot laser, etc., which can provide users with a complete robotic laser flight welding solution.

1.Suitable for multiple short weld seams with dense process requirements, it is very product design friendly and increases design and process flexibility.

2.Through the deep fusion with the trajectory planning layer of the German BLACKBIRD galvanometer, there is zero contact with the workpiece during the welding process, and the position of the weld seam can be changed flexibly, and the robot's movement is synchronized with the scanning and welding of the laser galvanometer, so as to realize the flight welding.

3.The waste of unproductive time caused by constant repetitive positioning before each welding section can be eliminated to the maximum extent possible, maximizing the laser beam on-line time, greatly shortening the production beat and increasing productivity.

Automotive Intelligent Arc Welding Application

Low spatter dynamic welding process + laser recognition adaptive technology

In the automotive industry, especially for the battery tray, dashboard, seats, front and rear subframes, non-load-bearing body chassis, crash beams and other core components of the arc welding process, there are a variety of materials resulting in unstable welding quality, low productivity, welding deformation is difficult to control, automation is not enough, the high cost and the impact on the environmental health of the industry pain points, which have a direct impact on the production efficiency, product quality and cost control. These pain points directly affect production efficiency, product quality and cost control. The QWAS ECO welding robot built by CLOOS, a subsidiary of Estun, is designed to address the pain points of the automotive welding industry by adopting low-spatter dynamic welding process and laser recognition adaptive technology, which significantly improves the welding quality and efficiency, reduces the production cost, and promotes the transformation of automotive manufacturing into intelligent and green, effectively solving the industry's problems.

1. QWAS ECO series robots are equipped with advanced low-spatter, dynamic welding process solutions for welding automotive high-strength steels, galvanized plates, and Series 6 aluminum alloys.

2. Self-developed laser recognition adaptive technology, breaking the application of large floor line gap problem, greatly improving the body-in-white welding qualification rate.

Focusing on the improvement and breakthrough of welding technology, Estun has always been committed to the in-depth integration of technological innovation and practical applications, and has crafted a number of benchmark applications for the industry, including spot welding, arc welding, laser flight welding and so on. These applications not only show Estun's excellent ability in welding precision, efficiency and stability, but also provide strong technical support and demonstration for the transformation and upgrading of the whole industry, helping the industry to move towards the goal of higher quality and higher efficiency.

Looking to the future, Estun will continue to plough into welding technology and explore uncharted territories, and will showcase more cutting-edge welding applications at the upcoming Industrial Fair. We look forward to joining hands with colleagues in the industry to promote the continuous progress and development of the welding field.
