Abstract: Provided is a slot die with variable manifolds and a controlling method thereof.

Abstract: Provided is a screen printing device. A screen printing device according to an embodiment of the present invention includes: a screen disposed adjacent to an upper portion of a substrate on which a printing process is performed, and having a pattern to be printed on the substrate; a printing unit disposed on an upper portion of the screen and configured to discharge ink supplied from the outside to the screen and to print the pattern on the substrate; a driver connected to at least one of the screen and the printing unit and configured to drive at least one of the screen and the printing unit; and a controller connected to the printing unit and the driver and configured to control operations of the printing unit and the driver, wherein, when at least one of the screen and the printing device moves in a state in which the printing unit contacts the screen, the controller controls the printing device to perform printing on the substrate by using discharge pressure of the ink.

Abstract: Provided is a slot die with variable manifolds and a controlling method thereof.

Abstract: Provided is a slot die with variable nozzles.

Abstract: The present invention relates to a slot die coating apparatus. A slot die coating apparatus according to an embodiment of the present invention includes: a slot die configured to perform a coating process by applying ink to a substrate; an image capturing unit disposed adjacent to the slot die and configured to capture a state of the slot die and a state of ink applied to the substrate during the coating process; and a control unit configured to compare an image captured by the image capturing unit with a reference image and control an operation of the slot die and a transfer of the substrate.

Abstract: The present invention relates to a slot die coating device and a control method therefor.

Abstract: Disclosed is a roll-to-roll printing apparatus, which includes n support rollers arranged in an n-gonal shape (where n is an integer equal to or greater than 3), a looped pattern mask having a plurality of pattern sections passing through inner and outer surfaces thereof and disposed so as to interconnect the support rollers, a driver that rotates the pattern mask, a transfer unit having an unwinder and a rewinder of a printing target and a backup roller that is disposed between two of the support rollers adjacent to each other and outside the pattern mask and that supports the printing target transferred from the unwinder to the rewinder, a printing unit disposed inside the pattern mask and discharging ink toward the printing target supported on the backup roller, and a tension adjusting unit adjusting tension of the pattern mask.

Abstract: Provided is a slot die for improving coating uniformity including a main body, a cavity formed in the main body, an introduction part formed at an upper portion of the main body to supply a coating solution into the cavity, an injection unit configured to provide an external ejection path for the coating solution with respect to a portion of or the entire cavity, and a guide member arranged in the cavity to help diffusion of the coating solution to the injection unit. Accordingly, the guide member arranged in the cavity can induce diffusion of the ejected coating solution so that the coating solution can be more uniformly applied.
