The Technology of the Industry 丨 Lyric High-speed Thermal Laminating Cutting and Stacking Machine Defined Speed and Precision from "Cell"

Under the background of the rapid development of the new energy era, the power battery and energy storage battery market is expanding at an unprecedented rate. Especially with the trend of energy storage battery evolving to large cells and large modules, the stacking technique is increasingly favored by the market. As the cornerstone of industry progress, the technological innovation of production equipment is particularly important. Adhering to the concept of building the business on technology, Lyric regards technological innovation, production efficiency and quality control as the core elements to enhance competitiveness, and has set a new industry benchmark in the field of high-end intelligent equipment. The high-speed thermal laminating and stacking machine developed by Lyric not only reflects this core value, but also represents the industry's top technological level.

01 Precise and efficient, achieving excellent quality
High-speed thermal laminating and stacking machine of Lyric shows many significant advantages in terms of technical performance. The production rate is stable at 480 pieces per minute (ppm), and the stacking speed reaches the industry-leading speed, which is 0.125 (s/pcs). For the length of 600mm plate, the cutting accuracy is controlled within ±0.15 mm, and the overall alignment accuracy of the battery cell is maintained at ±0.5 mm, ensuring the consistency of product size and enhancing the stability and reliability of the battery cell. At the same time, the yield rate of the equipment is maintained at over 99%, ensuring the quality of the products. The data reflects Lyric's meticulous attention to every detail to ensure that each cell has a more stable internal structure, superior safety and multiplier performance, and a longer cycle life.

02 Innovative design, simplified production process
The equipment adopts the concept of integrated design. It integrates functions such as unwinding, punching and slicing, hot laminating, separator cutting, stacking, cell hot pressing, gluing, unloading, etc., greatly simplifying the cell making process and significantly saving the equipment footprint. Through the application of precise tension control, multi-stage deviation correction, high-precision visual inspection and other advanced technologies, it realizes continuous unwinding of separator and material belt at a constant speed, which avoids the unstable factors brought by the cyclic tension change of traditional stacking machine. This not only makes the surface of cells more flat, but also eliminates the hidden problems of separator wrinkles and low quality of plates.

03 High-end quality control and dust removal system
In order to further improve the yield and safety of the products, Lyric has introduced a high-precision CCD inspection system, which can detect the appearance and size defects in milliseconds and adjust the cutting position in real time to ensure the perfect cutting of each plate. In addition, the Class 10,000 dust removal system is equipped to keep the operating environment of the equipment at an ultra-high cleanliness level, effectively preventing the impact of external pollution on product quality.

Focusing on the future, Lyric will adhere the core strategy of “building the business on technology”, unswervingly promote independent innovation, and continuously optimize the performance of the equipment, so as to inject new vitality and power into the lithium battery industry. At the same time, the company will further strengthen the depth of cooperation with partners, and jointly committed to the technological innovation and development of stacking equipment, to explore the frontiers of efficient battery production and high quality manufacturing.
