Abstract:
An apparatus for applying a viscous material, comprising:a syringe for holding a viscous material; a pressure apply device for applying pressure in an interior of the syringe; an application member for receiving and guiding the viscous material forcedly supplied by the pressure; a supply tube, connecting the syringe and the application member, for supplying the viscous material from the syringe to the application member; a discharge shaft inserted in an interior of the application member extending in an axial direction thereof and provided at one end thereof with a screw-like portion rotatable around a longitudinal axis thereof to forcedly move the viscous material guided by the application member in the axial direction; a nozzle for discharging the viscous material forcedly moved by the rotation of the discharge shaft; a rotation mechanism for rotating the nozzle around the axis; a holding device for firmly holding a substrate onto which the viscous material is applied, and a controller, wherein, under control by the controller, either or both of the nozzle and the holding device are moved to determine relative positions thereof, and the nozzle is moved down to discharge and then apply a predetermined volume of the viscous material onto a predetermined position of the substrate, wherein the supply tube is connected to the application member so that the supply tube is rotated together with the application member.
