Process layout

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.

Components

Robot

Injection molding take-out robot YUSHIN SCⅡ-150D (for insert loading) 5-axis Cartesian robot + 90° tilting arm Payload: 5 kg Repeatability: ±0.1 mm Stroke (robot specs): Travel 1,500 mm / Vertical 850 mm / Fore–aft 468 mm End-of-arm tooling (EOAT) / Tools Pneumatic grippers: 8 units (Insert loading 4 / Part take-out 4) 3-axis Cartesian robot for vision inspection (including a rotary tool Pneumatic grippers: 3 units (Vision inspection 1 / Orientation-change jig loading 2)

Peripherals

Insert injection molding equipment (optional / separate) Bowl feeder (BOWL FEEDER) Nut loading cylinder Finished-part transfer unit (post-insert) Insert orientation-change jig Vision inspection system

Workflow

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

Features

Improved Production Efficiency and Quality

Continuous, low-idle operation improves overall production efficiency.
Total inspection minimizes defect rates.
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.

Results

Key Benefits
Improved productivity, Minimized staffing by reducing control/management points
Client Feedback
Because machining cycle time was short, continuous operation was required
by deploying Seojeong’s solution, we increased production speed and were able to perform 100% inspection, which also improved product quality.
