摘要

PURPOSE: An automatic nozzle exchange system is provided to easily recognize the type, specification, and manufactured date of a nozzle by using a vision device for reading two-dimensional bar-codes. CONSTITUTION: An automatic nozzle exchange system comprises a nozzle head on which a nozzle(100) or picking up electronic components is mounted; the nozzle on which an information indicating element for providing information of the nozzle is attached; and a vision device(400) arranged at one side of the nozzle head so as to sense the information indicating element of the nozzle. The information indicating element is a two-dimensional bar-code(200) constituted by columns(210,220,230) and rows.
