Abstract

Provided is a paste dispenser and a method for controlling the paste dispenser. The paste dispenser includes a sensor part moving in a vertical direction perpendicular to a substrate, a nozzle part mounted on the sensor part, moving in the direction perpendicular to the substrate and a position measurement sensor outputting a change in a difference between the sensor part and the nozzle part as a digital signal. According to the present invention, a change in a position of the nozzle part with respect to a position of the sensor part is output as digital signals, without generating an electrical equivalent of noise. This makes it possible to precisely measure the distance the nozzle and the substrate and to largely reduce a defect percentage and a processing time for setting the vertical distance between the nozzle and the substrate.

Description

Technical field [0001] The present invention relates to a dispenser for dispensing paste, and more particularly to a dispenser for accurately setting the vertical distance between a substrate and a nozzle and a method for controlling the dispenser. Background technique [0002] The dispenser for dispensing paste is designed to dispense a variety of pastes (such as resistance paste and sealing paste) on a substrate in a predetermined pattern. [0003] The dispenser includes a table 40 on which a substrate is placed and a head unit. The head unit 50 includes: a container for containing the paste; and a nozzle connected to the container for dispensing the paste on the substrate. The dispenser moves the nozzle to keep the substrate fixed, moves the substrate to keep the nozzle fixed, or moves the substrate and the nozzle in different directions to form a paste pattern on the substrate. [0004] Before distributing the paste on the substrate, the vertical distance between the substrat...
