液体材料吐出装置及び方法
Document Type and Number:
Japanese Patent JP4435044
Kind Code:
B2
Abstract:
A liquid material discharge apparatus includes a syringe having a nozzle for discharging a liquid material, and a pressure control section for controlling pressure to be applied inside the syringe by means of a pressure medium and/or a pressure applying time period. The apparatus further includes an imaging device for imaging the shape of a liquid material discharged from the nozzle of the syringe, and an image processing section for calculating the length between a lower end of the liquid material and a reference position of the nozzle on the basis of the imaged shape of the liquid material. The pressure control section controls the pressure to be applied by the pressure medium and/or the pressure applying time period on the basis of the length between the lower end of the liquid material and the reference position that is calculated.
