Lishen Battery Production Line "driverless" is expected to have a capacity of 30 billion watt-hours in 2020

Laser cutting, polarizing, winding, assembling, injecting, cleaning, converting .... a small battery from preparation to production, needs to go through such a complex process. However, in the production workshop of Tianjin Lishen Battery Co., Ltd., there are hardly any workers in the huge workshops. With only a few display screens and several inspectors, the entire production line can be controlled for automation. On April 19th, the "New Age New Weather as a net media reporter to walk the grassroots and intelligent era today" organized by the Tianjin Municipal Party Committee Nettrust Office entered the new energy company Tianjin Lishen Battery Co., Ltd..

The production workshop of Tianjin Lishen Battery Phase 6 new factory was put into operation in November last year, with a total investment of 1.32 billion yuan and a total construction area of more than 50,000 square meters. The main production of square aluminum shell power cells and soft packaging power cells has an annual production capacity of 2.6 billion Watt-hours. Faced with the reporter's doubts about the production workshop he met, engineer Liuyuan gave the answer: "The biggest feature of the six new factories is production automation and management intelligence, which has created a new model for the company's smart manufacturing of lithium batteries. The new factory adopts a fully automatic production line and establishes a full-scale automated storage logistics system from raw materials to finished products, which realizes the automation of production processes such as winding, assembly, injection of liquid, conversion, and post-treatment. At the same time, through the introduction of MES system, products can be strictly online detection, determination, real-time transmission of data information, to achieve the battery life cycle monitoring and tracing. "

The winding machine is the core of the pipeline. It can automatically change the volume, automatically monitor, automatically correct the deviation, and collect the data in real time, organizing and calculating in the background. According to Liuyuan, there are 20 winding machines on a production line. The quality and level of products produced by each machine are not the same. They need to be analyzed and checked manually. Now using intelligent manufacturing and large data analysis, it is possible to monitor the alignment, length, width, and thickness of the winding in real time, helping producers quickly determine, test, and locate which machine has problems, greatly improving product quality and work efficiency. The previous generation winding machine can only complete 6-8 polar groups in one minute, and now it can complete 12 in one minute.

The work instructions and production dynamics of the workshop can even send information to the relevant responsible person's mobile phone to achieve remote command operations. In addition, for the sake of safe production, the production line is also set up to preform the function. In case of an emergency, the battery can be sent here for processing and will not affect the operation of other modules.

Under normal circumstances, a production line can be completely "driverless." Workers, like trafficspecial on the road, only need to observe the data, play a role in patrolling and commanding, in order to achieve precision and intelligence in production.

Gaojunkui, executive vice president of Tianjin Lishen battery Co., Ltd., told reporters that the intelligent production line and process process of battery assembly demonstrated the intelligent manufacturing concept of automation, digitization and networking. The battery module assembly line uses a large number of robots with intelligent vision to complete the feeding, assembly, transportation, and testing of the core and module, and the automation rate is as high as 100 %. Through the application of digital technology, each key component of the battery pack has established a complete product information tracing system, and realized the real-time collection, monitoring and early warning of component data during the assembly process, ensuring that the production is carried out in an orderly manner.

With six new plants in operation, the company's production capacity will reach 10 billion watt-hours in 2017, which will provide a source of power for 200,000 electric vehicles. By 2020, it plans to reach an annual production capacity of 30 billion watts, achieve an annual production capacity of 60 billion Watts in 2025, become a supplier of green energy solutions for all applications, and become one of the top three international consumer electronics supporting markets. It has become a major supplier of new energy vehicles, energy storage and special equipment supporting markets.
