As the next-generation core technology replacing traditional hot air and infrared drying, laser heating technology for high-speed coating machines possesses core advantages such as extremely fast drying, energy efficiency, and excellent quality in the industrialization process of high-end coating fields like lithium batteries and solid-state batteries. However, it still faces pain points such as high initial investment, insufficient operational stability, poor process adaptability, and difficult safety control, which severely restrict its large-scale implementation. This proposal is based on the two mainstream technological paths of existing VCSEL arrays and high-power semiconductor lasers, combined with the technical practices of companies like Lemon Photonics, Delong Laser, and Haimuxing. It proposes targeted solutions to address core pain points
