Sub-Second Character Segmentation on High-Speed Rotating Tyres

Reading embossed, black-on-black rubber characters on a rapidly spinning curved tire sidewall is one of the most demanding challenges in industrial computer vision. YAFE Quality Inspection AI solves this with synchronized multi-angle strobe illumination and proprietary polar unwrapping neural models.

✓
Curved Sidewall Coordinate Unwrapping: Mathematical coordinate transformation flattens 360-degree curved tire geometries into linear pixel arrays in under 35ms.
✓
Low-Contrast Embossed Rubber AI: Classifies black alphanumeric characters against black vulcanized rubber with tolerance for mold flash, rubber bloom, and surface dirt.
✓
Real-Time Schedule Validation: Instantly compares extracted Plant Codes, Size Codes, and Date Codes (WWYY) against factory MES production work orders.
✓
Sub-15ms Conveyor Diverter Trigger: Direct fieldbus signal trips pneumatic diverter flippers to isolate unreadable, expired, or non-conforming tires automatically.

TECHNICAL CAPABILITIES

Purpose-Built for Tyre Finishing & Compliance Lines

Engineered for high-volume tire manufacturing plants to automate regulatory compliance and guarantee 100% serialized batch traceability before shipment.

OCR

Embossed Alphanumeric Sidewall OCR

Reads low-contrast, raised rubber characters across curved sidewalls under continuous rotation at line speeds up to 120 tires per minute with 99.8% read rate.

TIN

Regulatory DOT & TIN Validation

Automatic parsing and verification of Plant Code, Tire Size Code, Optional Manufacturer Code, and Week/Year Date Code (WWYY) compliant with US DOT FMVSS 139, ECE, and BIS.

PLC

Deterministic Conveyor Rejection

Sub-15ms direct PLC communication via Profinet, EtherNet/IP, or Modbus TCP commands pneumatic flippers and diverters to isolate non-compliant tires instantly.

LOG

Cryptographic Audit Logging

Every inspected tire generates a permanent digital record containing high-resolution sidewall imagery, timestamp, curing mold ID, and serial code synchronized into SAP MES.

ROT

360° High-Speed Rotational Rig

Seamlessly integrates with automatic centering rollers and spin rigs up to 320 RPM, eliminating line pauses and manual tire reorientation.

RIM

13" to 54" Multi-Rim Agnostic

Automatic optical zoom and focal distance compensation inspects passenger car, commercial truck, bus, and massive agricultural OTR tires without mechanical re-tooling.

INSPECTION ARCHITECTURE

High-Speed 4-Step Sidewall Inspection Pipeline

Seamlessly retrofits into final finish lines, uniformity testing machines, and automated barcode sorting conveyor cells.

Step 01 • Centering

Centering & Spin

Mechanical conveyor rollers automatically center and spin the tire to optimal RPM for multi-camera synchronous capture.

Step 02 • Illumination

Polarized Strobe Capture

High-intensity polarized dome lighting highlights embossed rubber edges while eliminating glare from mold release wax.

Step 03 • Neural OCR

TensorRT Neural Inference

On-premises edge neural network unwraps the curved sidewall, segments characters, and validates alphanumeric TIN syntax in <400ms.

Step 04 • Dispatch

PLC Conveyor Sorter

Deterministic fieldbus signals route compliant tires to automated warehouse stackers and divert non-compliant tires for inspection.
