Lyric Pole Piece Laser Flight Cleaning: Precise Control, High Efficiency, Non-destructive

Amid the rapid development of the new energy vehicle industry, battery manufacturing technology continues to evolve, with increasingly stringent requirements for battery pole piece surface cleaning. Lyric's Pole Piece Laser Flight Cleaning technology, with its unique advantages of non-contact, pollution-free, high precision, and low damage, is gradually establishing itself as a crucial component in battery manufacturing. As one of the most promising green cleaning technologies of the 21st century, pole piece laser cleaning technology demonstrates vast application potential in battery pole piece processing and is now extensively integrated into key stages of power battery production, including pole piece manufacturing, cell production, and battery assembly.

In response to the challenges of traditional static cleaning technologies, such as high costs, low efficiency, and difficult maintenance, Lyric has strategically developed the Pole Piece Laser Flight Cleaning process. Through its independently developed high-efficiency Pole Piece Laser Flight Cleaning technology, Lyric has successfully addressed issues like poor process compatibility, low cleaning efficiency, and complex scanning paths encountered in laser cleaning of pole pieces. This innovation provides a new solution for optimizing next-generation battery products.

The core advantages of Pole Piece Laser Flight Cleaning technology lie in its efficiency, stability, and laser utilization. During the cleaning process, the laser beam can move continuously across the material's surface, with positioning and laser output occurring simultaneously, effectively eliminating the non-productive processing time found in traditional static cleaning methods. This not only significantly boosts cleaning efficiency but also ensures a high degree of consistency and reliability throughout the cleaning process.

However, with the continuous introduction of new materials and processes, enhancing the quality and efficiency of laser cleaning, particularly achieving laser scanning synchronized with axis motion in a flight state, has become an urgent challenge. Lyric has conducted in-depth research in this area, continually overcoming key technical difficulties. By optimizing the motion control system, Lyric has not only improved the precision and stability of laser scanning synchronized with axis movement but also ensured cleaning quality while significantly boosting cleaning efficiency.
