Zhongding intelligent logistics system assists power lithium battery efficient and safe production

The technology of “Intelligent lithium ion battery Production Intelligent Logistics Complete System” independently researched and developed by Wuxi Zhongding Integrated Technology Co., Ltd. passed the evaluation of scientific and technological achievements. The evaluation committee believes that the project results are at the domestic leading level in the field of lithium ion battery production logistics equipment technology and production management and control integration technology.

The special equipment for the production of power lithium batteries has extremely high requirements for logistics integration technology, and a slight error can cause a safety accident. Although there are many equipment manufacturers in the domestic lithium battery industry, they are mainly engaged in the manufacture of single special equipment, which cannot support the efficient and reliable operation of the entire intelligent production line, especially in the production logistics intelligent integrated system. At present, the core system integration technology and equipment in this field are basically monopolized by Japan and South Korea. It is not only expensive, but also has great limitations in the conversion of lithium battery models, and cannot meet the production requirements for frequent replacement of lithium battery models in China.

The power lithium battery production equipment is complicated, and the production process route is long. Each link directly affects the production efficiency, safety performance and performance of the lithium battery, especially the post-processing inspection and testing of the lithium battery (chemicalization, volume separation, charge and discharge test, etc.) Completed in a three-dimensional warehouse, the precise completion of various processes and the rapid switching between various process links are extremely demanding on the automated production logistics equipment and system integration technology. Any mistakes in the links may lead to explosion, fire and other dangers.

The project realizes logistics automation and information synchronization between various production processes of lithium batteries, collects relevant information of production process in real time, establishes traceability system of product quality, especially the risk of explosion in the production process of lithium batteries, which is difficult to find in the first time deal with. In China, due to many factors such as automated production logistics integration technology, production control system, safety assurance measures, etc., most of the equipment is still in manual operation or semi-automatic state, not only inefficient production, but also the quality of production is not guaranteed. It has affected the healthy development of China's power lithium battery and its supporting industries (new energy vehicles).

The project has the following innovations: (1)Developed a smart lithium-ion battery intelligent clamping and picking technology, combined with intelligent application technology such as robot and high-definition visual processing to achieve emergency disposal of dangerous goods. (2) Developed a temperature-controlled trigger system for lithium-ion battery airborne fire extinguishers. Fire-fighting devices are installed on the left and right sides of the stacker for lithium-ion battery access, including fire sensors, carbon dioxide fire extinguishers and fire extinguishing controllers. (3) The system integrates the online rapid automatic sorting technology of power lithium-ion battery, the energy feedback technology of special stacker, and the production control software system, which realizes the functions of efficient online elimination and energy-saving production of defective products.

The project has independent intellectual property rights and has obtained 14 authorized invention patents, 4 utility model patents and 13 software copyrights.

In addition, the project product is a typical intelligent complete system, which fully conforms to the theme of “National Medium- and Long-Term Science and Technology Development Plan (2006-2020)” and “Made in China 2025”.

Therefore, this technological breakthrough is of great significance to promote the overall development of the upstream and downstream industrial chain of China's power lithium battery, comprehensively improve the technical level of the intelligent manufacturing industry, and accelerate the realization of the national industrial 4.0 strategic goal.
