Electronic Component Insert Molding Automation Using a Yushin Take-Out Robot

#Yushin#Insertmolding#Steelplate#Overmolding#MoldingAutomation#Productivity#LaborReduction

Process Overview

This assembly automation solution uses a YUSHIN take-out robot (SCⅡ-150) to automate the process of insert-molding a steel plate into a plastic injection-molded part during production. By automating both the insert-loading operation and the downstream inspection process, the system minimizes control points while improving overall productivity.

Components

Robot	YUSHIN SCII-150D (for insert loading) 5-axis Cartesian robot + 90° tilting arm, payload 5 kg, repeatability ±0.1 mm Work envelope/stroke: Travel 1,500 mm / Fore–aft 468 mm / Vertical 850 mm 3-axis Cartesian unit: Vacuum grippers ×2
Peripherals	EOAT / Tooling - Tool changer (rotary type): tool change via rotation - Pneumatic grippers ×4 (for part take-out) - Vacuum grippers ×4 (for insert loading) Peripheral Equipment - Injection molding equipment (optional / separate) - Bowl feeder (steel plate feeding) - Steel plate loading jig - Finished-product discharge conveyor

Workflow

STEP 1.	Singulate and feed two steel plates at a time via the bowl feeder
STEP 2.	Pick two steel plates per cycle and place them into the 8-position loading jig
STEP 3.	Pick a set of eight steel plates and transfer them to the injection molding machine
STEP 4.	Take out the molded part and load the steel plates
STEP 5.	Discharge the finished product via the outfeed conveyor.

Key Features

Improved Production Efficiency and Quality

Continuous, low-idle operation improves overall production efficiency.
Fewer control points reduce the number of operators required.

Cost-Effective Performance with a Dedicated Take-Out Robot

A dedicated take-out robot enables a compact installation and overhead handling.
Optimized motion profiles support high-speed cycle operation.
Compared to articulated robots, this tailored solution minimizes upfront investment cost.

Implementation Results

ROI Period	18 months
Key Metrics	Improved productivity Minimized staffing by reducing control/management points Reduced insert-missing defects
Client Feedback	Because the machining cycle time was short, continuous operation was required; by deploying Seojeong’s solution, production speed improved significantly.
