Process Overview

This inspection automation solution uses the DENSO VM60B1 robot to automate quality inspection and protective film application for automotive parts by performing taping and inspection processes through robotic wrapping.

By switching between three tools, the system performs gate cutting, protective film application, and inspection in a single integrated workflow, minimizing management points and improving overall productivity.

Components

Robot	DENSO VM-60B1 6-axis articulated robot Working range: 1,298 mm Payload: 13 kg Weight: 82 kg Repeatability: ±0.07 mm Standard cycle time: 0.95 sec
Peripherals	Tool changer Ultrasonic cutter for gate cutting Wrapping unit Brush and vacuum gripper (for applying wrapping tape and transferring to inspection station) Peripheral component press-fit and rotation device Vision inspection system Weight inspection system Discharge conveyor

Workflow

STEP 1.	Place plastic parts on the jig
STEP 2.	Gate cutting with ultrasonic cutter
STEP 3.	Change to wrapping tool and apply protective film
STEP 4.	Change to brush and vacuum gripper and apply wrapping tape
STEP 5.	Pick the product and perform vision inspection
STEP 6.	Load onto weight inspection station and perform weight check
STEP 7.	OK/NG judgment via weight conveyor and discharge OK products

Features

Improved Production Efficiency and Enhanced Quality

Improves production efficiency through continuous operation by minimizing idle time
Minimizes cycle time by applying a high-speed industrial robot
Reduces defect rates by performing 100% inspection (visual and weight inspection)
Minimizes defect rates through weight inspection
Minimizes management points by automating gate cutting, wrapping, and inspection in a single process

Results

Key Benefits	Improved productivity Minimization of management points and reduced manpower input Improved defect rate through product inspection and weight inspection
Client Feedback	We initially expected automation to be difficult because multiple tasks had to be performed within a single process. However, by implementing an optimized solution using a tool changer, we improved production speed and achieved 100% inspection, resulting in enhanced product quality.
