摘要： There is provided a multi-slot die coater that is easy to adjust a coating gap and can achieve widthwise deviation control of the coating gap. According to the present disclosure, a step is formed between rear surfaces of die blocks through a fixing block including a step adjustment block. The step adjustment block has a preset thickness, and the step adjustment block is mounted between any one die block and a flat plate-shaped block, and the other die block is coupled to the flat plate-shaped block, 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 including the step adjustment block. Thus, it is possible to always maintain the distance of the front ends of the die blocks and the substrate, i.e., the coating gap at a desired level, and 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.

摘要： A multi-slot die coater has improved a deviation in a width direction of a slot gap caused by a structural feature including a thin die block. The multi-slot die coater including a lower slot and an upper slot includes a lower die block; an intermediate die block disposed on the lower die block to form the lower slot therebetween; and an upper die block disposed on the intermediate die block to form the upper slot therebetween, wherein the intermediate die block comprises a manifold that is a space provided from a first surface facing the upper die block toward a second surface that is an opposed surface of the first surface, accommodates a coating solution, and is communicatively connected to the upper slot, and wherein a shortest distance from distances from any points on a bottom surface of the manifold to any points on the second surface is equal to or greater than 10 mm.
