Provided is a liquid coating unit in which a linear movement mechanism (130) of a coating unit (4) comprises an eccentric plate (116), an eccentric shaft (114), a linear guide (132), a connecting plate (112), a movable part (108), a connecting shaft (110), and bearings (122, 124). The eccentric plate (116) is rotated by a servomotor (120) and is attached to a rotating shaft of the servomotor (120) that intersects the vertical movement direction of a coating needle holder (102). The connecting shaft is provided to the movable part (108), the movable part (108) moves vertically together with the coating needle holder (102), and the connecting plate (112) connects the connecting shaft (110) and the eccentric shaft (114) at a fixed length. When the eccentric plate (116) rotates as a result of the driving force of the servomotor (120), the coating needle (24) is moved upward and downward in a reciprocating manner together with upward and downward movement of the eccentric shaft (114). Configuring in this manner provides a liquid coating unit and a liquid coating device that make it possible to drive a coating needle at high speed. |
