Title: Jari Liimatainen: Innovator in Laser Coating Technologies
Introduction
Jari Liimatainen is a prominent inventor based in Tampere, Finland. He has made significant contributions to the field of laser coating technologies, holding a total of 9 patents. His innovative approaches have paved the way for advancements in various industrial processes.
Latest Patents
One of his latest patents is a lighthouse scanner with a rotating mirror and a circular ring target. This invention introduces a scanning arrangement and a method suitable for coating processes that apply laser ablation. The arrangement is designed for prolonged industrial processes and includes an annular target. The laser beam direction is controlled by a rotating mirror located along the center axis of the annular target. As the mirror rotates, the scanning line rotates circularly along the inner target surface, ensuring a constant spot size at the focal point of the laser beams.
Another notable patent is a method for coating separator films of lithium batteries, along with a coated separator film produced through this manufacturing method. This invention utilizes laser ablation to detach particles from the target, directing the vaporized particle flux to the base material to be coated. The method employs the roll-to-roll principle, where the base material is directed from one roll to another, allowing for efficient coating in the area between these rolls. Additionally, rotating mirrors and a telecentric lens are used to align the laser pulses before guiding them onto the target material.
