    Abstract: The present invention relates to a slot die coating device and a control method therefor. The slot die coating device according to one embodiment of the present invention comprises: a slot die for performing a coating process by coating a substrate with ink; an image capturing unit located adjacent to the slot die, and photographing a state of the slot die and a state of the ink coated on the substrate during the coating process; and a control unit for controlling an operation of the slot die according to a result of the comparison between an image captured by the image capturing unit and a reference image, wherein the slot die comprises: a first body having a cavity in which the ink supplied from the outside is accommodated; a second body arranged so as to be spaced apart from the first body; and a shim plate coupled between the first body and the second body, having an outlet communicating with the cavity so as to discharge the ink accommodated in the cavity, and having at least one protrusion part exposed to the outside of the first body and the second body, wherein the control unit sets the reference image on the basis of the at least one protrusion part and compares the image captured by the image capturing unit and the reference image.

    Abstract: Provided is a slot die with variable nozzles. The slot die with variable nozzles, which applies ink on a substrate to perform a coating process, includes: a first body having a cavity configured to accommodate ink supplied from the outside; a second body spaced apart from the first body in a transfer direction of a substrate or a direction opposite to the transfer direction; a shim plate coupled between the first body and the second body and having an discharge port configured to communicate with the cavity and discharge ink accommodated in the cavity toward the substrate; and a plurality of variable nozzles disposed at a lower end of the first body or the second body in a width direction of the substrate so as to be adjacent to the discharge port, wherein each of the plurality of variable nozzles is independently driven according to a state of the ink coated on the substrate and adjusts a partial discharge amount of the ink discharged from the discharge port by changing a partial area of the discharge port at an arrangement position thereof.
