  • Publication number: 20240136496
    Abstract: An electrode sheet drying equipment, an electrode sheet manufacturing system including the same, and an electrode sheet drying method including an air-floating roller disposed downstream of a drying oven, and the air-floating roller is configured to spray hot air through multiple air spraying holes formed on the outer circumferential surface. Accordingly, the electrode sheet discharged from the drying oven in a partially undried state can be additionally dried, thereby preventing contamination of a transfer roller and/or equipment of the subsequent process.

  • Patent number: 11947132
    Abstract: There is provided a camera module including a plurality of ball bearings to support the driving of a lens barrel at the time of compensating for unintended camera movement due to disturbance such as hand shake. The lens barrel may be driven in first and second directions, independently, by one driving force exerted in the first direction perpendicular to an optical axis and by another driving force exerted in the second direction perpendicular to both the optical axis and the first direction, thereby preventing driving displacement from being generated at the time of compensating for unwanted motion such as hand shake while securing reliability against external impact, and having reduced power consumption at the time of compensating for the disturbance.
