1. The iteration of the lithium battery industry: the dual test of manufacturing precision and scale
In the wave of global energy structure transformation to cleaner, lithium-ion batteries have become the core of driving new energy vehicles and building new energy storage systems. With the continuous improvement of battery energy density and power output, unprecedented high standards have been put forward for lithium battery production lines. Minor defects in the internal materials of the battery cells, as well as even slight deviations in the assembly process, may directly affect the cell consistency, cycle life, and even energy storage safety of the battery.
In the face of the dual pressure of large-scale expansion and high yield, lithium battery intelligent equipment must move from traditional automation to deep intelligent manufacturing. With its accumulation in the field of precision equipment technology, Dexin Intelligent Technology (Dexin Intelligence) is focusing on providing high-standard new energy intelligent equipment, and is committed to giving high-level safety and reliability to lithium battery products from the manufacturing source.
2. Core manufacturing process: achieve high-precision battery cell assembly
In lithium battery production lines, the manufacturing of battery cells is the key to determining product quality. Dexin Intelligent Technology's equipment incorporates advanced precision control technology into key processes:
1. Precision and stability of lamination process
For prismatic and pouch batteries, the lamination process of pole pieces and separators is the core that determines the stability of the internal structure of the battery. The accuracy of pole alignment directly affects the internal resistance and thermal management performance of the battery. Dexin Intelligence's laminating machine adopts a high-resolution vision system combined with a precision linear motor to achieve high-precision control of pole edge alignment. At the same time, the equipment ensures that no damage is caused to the electrode pieces or separators during high-speed production processes through precise tension control and flexible manipulators, thereby significantly improving the consistency of battery cells.
2. Stress-free integration of battery cell assembly
After the battery cell is completed, the subsequent high-precision battery cell assembly links such as shell insertion, tab welding and top cover assembly require precise and "gentle" operation. Dexin Intelligent Equipment uses high-sensitivity force control sensors to monitor small stress changes during the assembly process in real time, ensuring that the battery cells are not subjected to external extrusion and deformation during the assembly process, maintaining the integrity of the internal structure and avoiding potential short circuit risks.
3. Module PACK and safety defense line: high-level security guarantee of the system
After the battery cells are integrated through the module PACK, they form the core of the system. The manufacturing quality at this stage is directly related to the energy storage safety of the end application.
1. Laser welding and real-time quality monitoring
In the module PACK process, laser welding is the main way to connect the cell pole and busbar. Dexin Intelligence's welding equipment integrates advanced vision inspection and real-time process monitoring systems. The system not only ensures precise positioning of the laser focus, but also collects process parameters such as power, speed, and temperature in real time during the welding process, forming full-process traceability data. This refined control helps reduce welding defects and ensures long-term reliability of the connection.
2. Comprehensive security detection and data integration
Dexin Intelligence's new energy intelligent equipment has set up a comprehensive safety inspection station at the end of the PACK line. This includes high-precision air tightness testing, insulation withstand voltage testing, etc. More importantly, all manufacturing and inspection data is uploaded to the customer's manufacturing execution system (MES) through the equipment interface, forming a full life cycle traceability chain from feeding to delivery. Through the support of data, users can accurately evaluate the manufacturing quality of each set of battery modules, providing an important basis for subsequent operation and maintenance and cascade utilization.
