PICK-UP UNIT OF A PICK-UP DEVICE

摘要

PURPOSE: A pick-up unit for a pick-up device is provided to individually unload the objects picked by an adsorption head by blocking each adsorption hole with a packing member of a valve body by turns. CONSTITUTION: A pick-up unit of a pick-up device comprises a housing(10), an adsorption head(13), a valve body, and an actuating unit. The housing has a chamber and an air ejecting hole(12) to discharge air in the chamber. The adsorption head is arranged at the bottom of the housing and has multiple adsorption holes communicating with the chamber. The valve body is coupled to maintain the airtightness of the chamber so that a vacuum section and a non-vacuum section can be divided. The valve body has a packing member individually blocking the adsorption holes. The actuating unit is coupled to the housing to move the valve body along the adsorption holes.
