Abstract:
1. An active material coating apparatus comprising: a lower die having a groove for supplying an active material in a slurry state wherein the lower die forms a first lip portion of an outlet slot connected to the groove which outputs the active material; an upper die disposed on an upper side of the lower die to face the first lip portion, wherein the upper die has a second lip portion of the outlet slot, and further has a hinge portion at a rear of the second lip portion according to an outlet direction of the active material, the upper die including an adjusting screw that is screw-coupled to the hinge portion to be controlled in a clockwise direction or a counterclockwise direction, wherein the upper die is assembled to the lower die; a fixing spacer having a first thickness interposed between the lower die and the upper die at the rear of the hinge portion according to the outlet direction of the active material and wherein the fixing spacer determines a fixing gap; a flexible spacer having a second thickness greater than the first thickness supported by an end of the fixing spacer so as to be movable in a width direction of the fixing gap wherein the flexible spacer is interposed between the first lip portion and the second lip portion on both sides of the width direction of the outlet slot and forming a variable gap, wherein the flexible spacer is configured such that rotation of the adjusting screw moves the second lip portion in the z-axis direction with respect to the first lip portion such that a position control of a y-axis direction of the flexible spacer between the first lip portion and the second lip portion is achieved; and a controller installed to the upper die and moving the second lip portion with respect to the hinge portion to control the variable gap between the first lip portion and the second lip portion.
