Defect Inspection of Cutting Tools using Doosan Cobots and Keyence Equipment

Industry > Metal·PlasticsApplication > InspectionSector > Manufacturing

This vision inspection solution utilizes the Doosan M0609 collaborative robot and the Keyence Image Dimension Measurement System (IM Series) to automate the dimensional inspection and defect sorting of cutting tools.

Previously, operators had to manually measure each part and perform visual inspections, which often led to human error in sorting and required a high amount of labor for simple, repetitive tasks.

By implementing robot automation, inspections are now performed continuously without idle time. This has increased the precision of defect detection, simultaneously improving both productivity and product quality.

Components

Robot	Robot: Doosan M0609 6-axis articulated collaborative robot with 6 integrated torque sensors. Payload: 6kg Reach: 900mm Repeatability: ±0.05mm Weight: 27kg Inspection System: Keyence IM Series Automated image dimension measurement system for high-speed, high-precision verification.

Workflow

STEP 1.	Picking: The robot picks a cutting tool from the supply tray.
STEP 2.	Cleaning: The tool is placed into an air-blowing device for cleaning to ensure accurate measurement.
STEP 3.	Inspection: The robot loads the tool into the Keyence vision inspection system.
STEP 4.	Sorting: Based on the measurement results, the robot classifies and sorts the tool as either Pass (Good) or Fail (Defect).
