Publication number: 20250041894Abstract: There is provided a multi-slot die coater in which a step is formed between rear surfaces of die blocks through a fixing block having a step portion. The fixing block has the step portion of a preset height, and any one die block is coupled to the step portion and the other die block is coupled to the other portion than the step portion, and thus the step is naturally formed between the rear surfaces of the die blocks by the coupling of the die blocks to the fixing block. Thus, it is possible to always maintain the distance of the front ends of the die blocks and the substrate, since the fixing block is fixed between the die blocks, once it is set, the coating gap does not change and is maintained during the process, thereby suppressing the widthwise coating gap deviation.Type: ApplicationFiled: October 23, 2024Publication date: February 6, 2025Applicant: LG Energy Solution, Ltd.Inventors: Taek-Soo Lee, Shin-Wook Jeon, Sang-Hoon Choy, Young-Gon Kim
