From relying on manual production scheduling to achieving precise minute-level scheduling, from paper-based document circulation to full-chain data integration - the smart factory of Dongguan Huanyu Yuan Technology Co., Ltd. has elevated the production efficiency and quality of lithium battery modules to a completely new level. 

As a national high-tech enterprise specializing in lithium battery modules and a provincial "specialized, refined, distinctive, and innovative" enterprise, Huanyuanyuan Technology, on the basis of having already deployed the MES system, takes "intelligent upgrade" as the core driving force. Relying on the digital control platform centered on the MES + WMS system, it steadily advances the construction of a smart factory and builds an intelligent operation system covering the entire chain of R&D, production, warehousing, and management, setting a practical example for the digital transformation of the industry. 

01  Top-level Design: Establishing a Full-Process Intelligent Foundation 

The Huanyu Yuan Smart Factory follows a four-level integrated architecture of "strategy - decision-making - operation - manufacturing", and builds an intelligent collaborative foundation that covers the entire business process. 

At the system level, two core systems, MES and WMS, have been deeply deployed, and they have been fully integrated with other systems such as ERP, PLM, and BI. This has enabled the connection of data from various links including product design, production execution, warehousing and logistics, and financial management, achieving the goal of "collecting once and sharing throughout the entire chain". 

At the infrastructure level, the "dual-gigabit broadband redundant access" solution is adopted. Separate dedicated network segments are allocated according to scenarios such as research and development, production, and office work to ensure high-speed and stable data transmission. At the same time, core production data is encrypted for storage and multiple backups are implemented. All devices are interconnected and data is collected in real time, enabling the empowerment of intelligent production. 

02 Implementation Path: Adopt a step-by-step practical approach 

WanYu Yuan Technology adheres to the implementation concept of "starting from the individual and progressing in stages", and systematically advances in three phases: 

Single-point breakthrough, creating a sample production line for the upgrade of MES 

Taking key production lines as the pilot, the core modules of the MES system were deployed, and the closed loop of process modeling and real-time data collection was completed. Relying on the upgraded system's functions of precise scheduling, full-process traceability, and online quality management, the effectiveness of the MES upgrade in improving production efficiency and quality was verified, laying a practical foundation for the subsequent comprehensive promotion of the MES system. 

② Expand horizontally to achieve full coverage of the entire production process 

After the successful verification on the sample production line, the MES system will be fully promoted to all production lines, and the WMS warehouse management system will be deployed simultaneously to achieve data linkage between production and warehousing, and the integration with ERP and PLM systems will be initiated to build an "planning - execution - data" integrated closed loop. 

③ Achieve vertical integration and establish intelligent collaboration throughout the entire value chain 

Based on the in-depth application of the MES system, the system integration is further enhanced, SRM is incorporated into the supply chain collaboration system, and the specialized digital transformation of the precision production line is completed. The MES production data is extended to the R&D, supply chain, and customer service links, achieving intelligent collaboration and data-driven decision-making throughout the entire factory and the entire supply chain. 

This step-by-step MES upgrade path not only controls the risks of system upgrades but also ensures the sustainable expansion of digitalization achievements, laying a systematic foundation for the long-term evolution of the smart factory. 

03 Scene Empowerment: Enhancing Quality and Efficiency throughout the Entire Business Chain 

Based on the intelligent foundation constructed through the upgrade of the MES system, Huanyu Yuan Technology has achieved significant operational improvements in its core application scenarios: 

Production Execution: 

Based on the upgrade of the MES system, minute-level automated scheduling and precise task distribution have been achieved, replacing the traditional manual production scheduling and paper-based circulation mode. The system-driven refined management has increased the production achievement rate from 93%-96% before the upgrade to 99.94%. The production progress and equipment status can be viewed in real time, and the problem response efficiency has been improved to the minute level. 

Quality Control: 

Relying on the integrated quality management module of MES, the online unified maintenance and real-time update of inspection standards have been achieved. Through systematic detection and electronic quality inspection processes, the qualified rate of product quality has increased from 97.32% before the upgrade to 98.86%, and a full-process quality traceability system from raw materials to finished products has been established. 

Warehousing and Logistics 

Through the deep collaboration between the WMS system and the upgraded MES, precise storage location management, barcode-based inbound and outbound operations, and real-time inventory visualization are achieved. This effectively addresses the traditional warehouse pain points such as "difficult inventory search" and "cumbersome inventory counting", and optimizes the material scheduling and distribution efficiency through the system. 

Decision Support 

Based on the comprehensive integration of data from systems such as MES and WMS, an enterprise-level BI management cockpit is constructed to enable real-time visualization and intelligent analysis of key indicators such as orders, production capacity, and quality. This promotes the shift from "experience-driven" to "data-driven" management decision-making. 

04  Guarantee Mechanism: Dual-driven by talents and the organization 

The company established an IT Informationization Department specifically responsible for system operation and continuous optimization. Through special training on the MES system and cross-departmental practical exercises, the overall digital literacy of all employees was enhanced. Employees from departments such as production, quality, and PMC were able to proficiently operate the system, forming a virtuous cycle of "system empowering people and people optimizing the system". 

The value of this digital upgrade goes beyond the improvement of operational efficiency and product quality. It has also built three new core capabilities on the basis of the original manufacturing capacity: customer-driven agile delivery capability, full life cycle traceable quality assurance capability, and data-driven collaborative innovation capability. 

In the future, Huanyu Yuan will continue to deepen the integration of digitalization and the real economy, improve the intelligent collaboration system, and steadily move towards the goal of "becoming a benchmark in the global cylindrical lithium battery system field", contributing new impetus to the high-quality development of the manufacturing industry.
