Cutting Tool Tip Inspection & Laser Marking Automation

Content

Process summary: Tip feeding → robot pick-up & transfer → vision inspection (automatic OK/NG judgment) → laser marking → finished-part discharge, fully automated
Key configuration: 6-axis collaborative robot + LED ring-light vision camera + fiber laser marker + multi-axis HMI control system
Benefits: fully unmanned inspection & marking / real-time automatic OK·NG judgment / high-speed continuous processing

Process Overview

✔ Tip feeding → robot pick-up → vision inspection → laser marking → finished-part discharge — the entire process is fully automated
✔ LED ring light + high-resolution camera deliver real-time automatic OK/NG judgment — defects are sorted out instantly
✔ Fiber laser marking provides automatic serial / spec marking on each tip, enabling full traceability

Key Components

6-Axis Collaborative Robot (Handling) Precisely picks cutting-tool tips from the feed tray and automatically transfers them to the inspection and marking stations. A blue cable drag chain keeps the wiring safely managed, and the robot flexibly handles various tip geometries. Handling / Transfer	Vision Inspection Station LED ring lighting and a high-resolution camera capture detailed images of the tip surface, edges, and shape. Vision software analyzes dimensions and defects in real time, automatically classifying OK (green) / NG (red) and sorting instantly. Vision Inspection / Quality Sorting
Fiber Laser Marker Precisely laser-marks serial numbers, specifications, and lot information onto tips that pass inspection (OK). The black-housing laser head is routed through a blue cable drag chain and marks without contact, causing no damage to the tip. Laser Marking / Engraving	Integrated HMI Control System A dual-monitor HMI displays vision inspection results, process flow, and fault alarms in real time. PASS/OK and FAIL/NG status is shown at a glance with color coding, while inspection history and statistical data are automatically saved and managed. Control / Monitoring
Tip Feed Tray A black anodized tray that loads various tip shapes — such as diamond and triangular cutting-tool tips — in a grid array. It is precisely aligned with the robot pick-up coordinates and feeds continuously, tray by tray. Feeding / Loading	Inspection Jig & Fixture Plate A yellow pneumatic clamp jig accurately holds the tip at the vision inspection position. On the black anodized plate it ensures highly repeatable positioning and is compatible with a wide range of tip specifications. Jig / Fixturing
