/PRCWT/Shanghai, December 05, 2023 - The 8th International Summit on Power Battery Applications (CBIS2023), hosted by China Chemical and Physical Power Supply Industry Association and Battery China Network, was successfully held in Shanghai on November 28-30, 2023. With the theme of "Service, Cooperation, and win-win - Embracing the 'New Globalization' era", the summit attracted experts, executives, and industry representatives from various fields of new energy vehicles, power batteries, and energy storage industry chains at home and abroad to participate and jointly discuss the development of the industry in the context of globalization.
As an industrial Internet solution provider serving the discrete manufacturing and process manufacturing industries, Zhanwan Technology was invited to participate in the summit. At the theme forum of "Digital Intelligence Empowering New energy battery Industry", Tang Yue, CEO of Zhanwan Technology, with the title of "High efficiency Code for the construction of new energy lithium battery digital Factory", shared in detail that Zhanwan Technology empowers the development of new energy material head enterprises through digitalization and intelligent high efficiency code, helping enterprises to solve a series of pain points such as production quality, yield, efficiency and cost. It was highly concerned by the participants.
From the digital entry, improve quality consistency, quickly shorten the "quality climbing period"
Njie is the world's leading lithium battery separator manufacturer. In recent years, with its technological advantages and the expansion of industrial scale, NJIE has successfully entered the supply chain of the world's first echelon lithium battery manufacturers, and has global competitiveness in terms of capacity scale, product quality, cost efficiency, and technology research and development. For Njie Shares, the downstream demand is strong, and it is the key core to continuously optimize the production process, improve the consistency of diaphragm quality, and quickly shorten the "quality climbing period".
Through a digital factory platform, Exhibition Bay Technology conducted a "comprehensive physical examination" of the Njie plant, found and diagnosed problems in the diaphragm production line and carried out global optimization. Based on the Zhanwan Technology industrial Internet platform, the core process parameters of the diaphragm production line are automatically collected by IoT, and are connected to MES, BI and other systems to achieve equipment interconnection. Through SPC mathematical tools such as X-R management chart and P management chart, combined with the parameters collected by IoT, the production SOP is used to monitor the change trend in real time, give early warning to possible risks, and automatically generate abnormal records of the production line. According to the quality inspection results, track and optimize the process of the diaphragm production line, improve the production capacity of the diaphragm production line and stabilize the yield.
The key production process parameters are automatically collected, the labor cost is reduced, and the equipment data management is paperless and less human. The precision optimization control of the process is shortened from the original interval of every 2 hours to every 5 minutes; Turn post-inspection into pre-warning, reduce quality defects, improve process quality by 10%, and ensure the consistency of product quality.
From digital to intelligent, equipment intelligent counter-control, enhance quality control capabilities
In order to promote the localization of the aluminum-plastic film market, Njie Shares have laid out a production base with aluminum-plastic film as the core, and its dry and thermal processes can meet the market demand, mainly used in power, energy storage, 3C and other fields. In the new energy battery aluminum-plastic film generation process, the raw material cost is high. After the smooth process, the semi-finished masterroll will be cut off in the slitter machine according to the finished product specifications and cut into several finished rolls. In the traditional production process, the scuttling machine equipment and the upstream defect detection data are not connected, and can not be automatically controlled, and the human work scuttling efficiency is low and the cost is high.
From the digital "medical examination report", the diagnosis found that improving the slitting efficiency of the aluminum-plastic film production line is the key core to improve production capacity. Based on this, Zhanwan Technology has created equipment intelligent counter-control solutions for Njie Shares, showing a demonstration role in the entire industry. The process parameters and defect information of multiple production lines can be collected automatically by connecting the slabbing machine equipment and upstream defect detection equipment. Through automatic identification of defect length, combined with automatic control system, the downstream slitter is counter-controlled to realize automatic defect collection and processing.
Manual screening and recording of scuttling defects are optimized for automatic system control and processing, which increases production efficiency by more than 3 times, reduces labor costs and improves product quality. Moreover, after the successful pilot of the equipment intelligent counter-control solution in Jiangxi base, it was rapidly promoted and applied to a number of factories of Njie Shares, giving full play to the leading role of the typical model.
From digitalization to intelligence, 1+X helps enterprises break through difficulties and enhance core competitiveness
Relying on its landing experience in the fields of industrial equipment networking, big data analysis and scenario-based application, Zhanwan Technology has created 1+X industrial Internet innovative solutions. "1" is a digital factory platform, that is, driven by KPI indicators of factory operation, KPI is decomposed into five modules: equipment, production, quality, energy carbon and safety environment, collect data of factory equipment and operation, analyze data and diagnose problems based on industry Know-how. "X" is the application of X intelligent scenarios, that is, problems found through a digital factory platform, and algorithms and mechanism models are used to solve problems for different scenarios.
Finally, Tang Yue summed up the power of 1+X in an easy-to-understand way. "For enterprises, digitalization and intelligence are two things, digitalization is to collect and analyze data through the industrial Internet platform, and scan and diagnose the five core dimensions of the factory's production, equipment, quality, energy carbon, and safety environment." For the problems found in the digitization process, intelligent means such as AI algorithms and automatic control systems are used to solve the problems, helping factories improve quality, increase efficiency and reduce costs. In general, digitalization is a 'comprehensive physical examination' to find and diagnose problems, and intelligence is a 'right medicine' to solve problems."
