Busbar as an important conductive connection component in lithium batteries, its welding quality is directly related to the safety and performance stability of lithium batteries. However, the traditional manual welding method has low efficiency, unstable quality and other problems, and is difficult to meet the needs of mass production.
ESTUN robotic automation welding solution helps the world's leading power battery manufacturers to solve the dilemma of manual welding, and improve the production efficiency and welding quality.
Static Laser Welding, Dynamic Flying Welding
ESTUN provided the enterprise with a robotic welding solution to automate the busbar welding station on the production line. The complete solution is centered on two ER220-3100 six-axis robots, together with key components such as vision system, laser system, high-precision fixtures, and safety guards, etc. According to the actual needs of the production line, the layout of the workshop is optimized and adjusted to ensure that the robots can move and operate smoothly.
ESTUN has also taken a crucial step towards the gaps in Chinese domestic robots in the field of flight welding:
ESTUN builds a mature solution for lithium-ion batteries, helping to increase the speed of the production line by 30%. The robotic automated welding solutions have significant advantages over traditional manual welding solutions.
First of all, industrial robots can realize high-efficiency welding, quickly adapt to the production needs of different products, provide flexible production capacity, and automated processes enable the production of more battery cells per day to meet the growing market demand.
Secondly, automated robotic welding is characterized by high stability and reliability, which reduces welding quality problems caused by human factors. Consistent welding improves battery performance and reliability, and results have also shown that automated production lines produce batteries with a pass rate of more than 99%.
Thomas (ESTUN Engineer) said, "Our mature power battery welding solution not only meets the production needs of this enterprise, but also has a high cost-effective and scalable, and can better meet the needs of future production."
In addition, robotic welding reduces labor costs, improves the working environment and reduces the risk of workplace accidents to 0.
The workshop director of this power battery manufacturer said, "Compared with traditional manual welding, robotic welding can realize 24-hour uninterrupted work, which brings us an unprecedented increase in production capacity, they can complete the welding task of a station in 300s, and we have increased the speed of our production line by 30%!"
Digital Technology Brings Quality and Efficiency Improvement, Lasting Business Value
ESTUN also provides comprehensive industrial digitalization services for the entire production line of this power battery manufacturer, and the application of digital technology further enhances the transparency and traceability of the production process. By uploading the data collected by welding equipment and sensors to the cloud platform or intranet in real-time, managers can monitor the production status in real time and quickly respond to problems on the production line. This real-time data visualization not only helps to improve production efficiency, but also enables data analysis to identify potential improvement points in the production process, helping enterprises to improve product quality and reduce rework and scrap rates.
Meanwhile, based on ESTUN's in-depth research on various industries and its wide application in the whole industry and competitive advantage of the whole industry chain, ESTUN has also developed an exclusive industry experience library and integrated it into its own digital technology. As a result, the digital production line can identify 100% of robot faults and locate them accurately, with more specific and accurate alarm descriptions.
"The comprehensive industrial digitalization solution has helped us open up the equipment and management data pathway, digging deeper into the value of equipment operation data, and to a certain extent, it has contributed to the enterprise's cost reduction and efficiency." The power battery manufacturer's project leader added. "As technology continues to advance in the future, our welding operations will also become more intelligent and automated due to the addition of digital technology, and these advances will undoubtedly contribute to the successful and sustainable development of lithium battery manufacturing."
