went from hand-crafting the first motor to end the history of Mindong 's industrial "zero", to now Ningde era has been selected as the "Global Lighthouse Factory" by virtue of its extreme manufacturing, through the efforts of several generations of "weak birds fly first, dripping water penetrates stone", Ningde's industrial history has turned a new page - "Extreme Manufacturing" creates the limit
Recently, during the 2022 German International Transportation Expo (IAA Transportation), Ningde Times signed a cooperation agreement with a number of world's leading vehicle companies , and won the " Daimler Truck Supplier Award", which once again demonstrates CATL's innovative ability and wide market recognition in the new energy industry.
This is the first appearance of CATL with a new generation of advanced technologies and products in the commercial field at the 2022 German International Transportation Expo. At the exhibition, leading innovative products such as CATL's high specific energy batteries, fourth-generation innovative battery packs, MTV products, long-life battery packs, low-voltage platform modules, sodium-ion batteries , and fast-charging batteries have won visitors frequent stops to understand watch.
Ningde lithium battery new energy industry base
Ningde era's global leading products are the support of the world's leading manufacturing processes and technologies, the core of which is the realization of extreme manufacturing. Under the background of "double carbon", the lithium battery new energy industry will enter the TWh era. In order to cope with the increasingly complex manufacturing process and meet the demand for high-quality products, CATL put forward the concept of "extreme manufacturing" in 2020.
faced the three major challenges of "high quality requirements, extremely complex technological processes, and extremely fast production speed", CATL used the seven ABCDEFG enabling technologies for intelligent manufacturing to establish an extreme manufacturing system framework and build an intelligent manufacturing platform. As the core, a multi-platform, multi-system in-depth interactive industrialization and information integration ecological platform supports the realization of the ultimate manufacturing goal.
Ningde era production workshop
is in the world's largest lithium battery new energy base. The Ningde era factory can produce one battery cell every 1.7 seconds on average. The speed of coating equipment can reach 100 meters per minute, and the equipment can precisely control product size from microns. There are more than 6800 quality control points in the whole production process, and the average traceability data of each battery exceeds 10,000 items. Manufacturing" charm.
"Our stereotypes about traditional industries are always based on 'big'. The CATL era is just the opposite, taking you to the limit of the micro and nano-level micro world." The relevant person in charge of the Municipal Bureau of Industry and Information Technology said. Coating is the core process of lithium battery production. The slurry mixed with various raw materials should be uniformly coated on the 4.5-micron thin copper foil and aluminum foil. The core global challenge is coating. consistency.
The traditional coating machine is mostly imported from Japan. Relying on the long-term rich coating experience in the film industry, Japan developed the lithium battery coating equipment that represented the most advanced level in the world at that time. It is not technically dependent on imports for China's lithium battery industry. Long term plan. In this context, the Ministry of Industry and Information Technology organized a major project for the new model of intelligent manufacturing. As an industry leader, CATL took the lead in jointly tackling technical problems with and internal equipment manufacturers, and successfully independently developed a domestic high-speed coating machine, and achieved the goal of extreme manufacturing. Under the guidance, a large number of technical personnel were invested to develop the coating central intelligent control system.
Today, the battery factories built by CATL at home and abroad are all using domestic coating machines and domestic software, breaking the foreign monopoly on coating machine technology.
Ningde era smart factory uses 5G AGV equipment for material handling
In the Ningde era factory, you can see the latest application of 5G era artificial intelligence everywhere. For example, in the die-cutting process, the camera quickly passes through its field of view at a speed of 80 meters per minute, accurately captures the high-definition image of each product, and analyzes the image in real time through artificial intelligence algorithms, so as not to miss any flaws. It has truly achieved a zero missed kill rate of product exceptions.
CATL can easily deal with complex technological processes through the "central intelligent process perception control system + augmented reality expert system". The central intelligent process perception control system connects all the equipment and instruments related to the coating machine in the workshop, and cooperates with AI technology for automatic management.The coating parameters are adjusted in real time, which can solve the problems of difficult quality control and complicated manual operation.
reporters saw at the scene that technicians use AR/VR glasses to synchronize and interact with the front-end and back-end information of the production operation site and the command background in real time. , remote guidance and other functions to improve the work ability and efficiency of the operation site.
Now, CATL has built an industrial Internet architecture based on 5G. Relying on its technological advancement in high bandwidth, low latency, and wide connectivity, it solves the difficulties and pain points of extreme manufacturing. Through the collision and integration of 5G technology and extreme manufacturing, CATL has explored 22 high-value business scenarios. At present, 9 5G integration applications have been implemented, and CATL is accelerating towards the goal of 5G factories.
Ningde era uses advanced machine vision, artificial intelligence, 5G, fluid control and other technologies to break through the four "limits" of speed, yield, labor productivity and energy consumption, and the coating speed is increased from 30 meters per minute to 100 meters per minute. It can produce a battery in 1.7 seconds, and the defect rate is reduced to one in a billion at the same time. At the same time, the human efficiency is increased by 75%, and the annual energy consumption is reduced by 34%.
In 2019, Ningde Times was rated as the first batch of "Intelligent Manufacturing Benchmark Enterprises" by the Ministry of Industry and Information Technology. In 2021, Ningde Times was rated as "Global Lighthouse Factory" by the World Economic Forum, becoming the first battery factory in the world to receive this honor.
