Process Overview

This assembly automation solution uses a YUSHIN take-out robot (SCⅡ 150) to perform insert molding, placing a nut into the mold and overmolding it with plastic, followed by automated inspection. By automating both the insert-loading operation and the downstream inspection process, the system minimizes quality-control touchpoints while improving overall productivity.

작업순서

STEP 1.	Feed and singulate nut blanks via the bowl feeder
STEP 2.	Pick four nut blanks
STEP 3.	Load them into the insert-molding station
STEP 4.	Take out the insert-molded parts and load them onto the finished-part transfer unit
STEP 5.	Move the parts to the orientation-change jig
STEP 6.	Pick parts one-by-one for vision inspection
STEP 7.	Sort and discharge into trays based on inspection results
