Abstract

Provided are a pump position feedback type dispenser and dispensing method, in which an image of a work, to which a viscous liquid is to be dispensed, is captured to determine an accurate position and direction of the work, and then a position of a pump is received in real time so as to dispense the viscous liquid to the work while ensuring that the pump reaches the accurate position of the work.

Description

[0001] Cross-references to related applications [0002] This application claims the benefit of Korean Patent Application No. 10-2015-0151759 filed in the Korean Intellectual Property Office on October 30, 2015, the disclosure of which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates to a pump position feedback type dispenser and method of dispensing, and more particularly to a pump position feedback type dispenser and method of dispensing in which capture will dispense a viscous liquid ) of the workpiece to determine the exact position and orientation of the workpiece, and then receive the position of the pump in real time to dispense the viscous liquid to the workpiece while ensuring that the pump reaches the exact position. Background technique [0004] In an underfill process performed by coating a semiconductor chip with a viscous liquid or a process for coating a light-emitting diode (LED) with a phosphorescent...
