Multi-Sided Thread Inspection Sort System
Multi-view thread damage inspection for fastener sorting lines
This solution architecture is designed to inspect external threads in sorting environments where part rotation or indexing is undesirable. Multiple synchronized views are arranged around the inspection zone to provide the coverage required for the application. Inspection logic is configured to your acceptance criteria and integrates into sorting workflows through pass/fail outputs.
What it solves
- Detects external thread damage using multi-view inspection rather than a single camera angle
- Reduces reliance on mechanical rotation/indexing when those mechanisms add jams, wear, or maintenance
- Produces consistent pass/fail decisions tied to defined acceptance criteria
- Supports integration into existing sorting workflows with scope-appropriate electrical interfaces
How it works
- Parts are presented in a stable, repeatable position through the inspection zone.
- Multiple synchronized cameras capture views around the part as it passes (no required part rotation for inspection).
- Inspection logic evaluates thread condition against the acceptance criteria defined for the job.
- Results are output as pass/fail and logged; downstream reject/sort actions are handled per the integration scope.
Camera, scanner, and sensor selection is application-driven to match the part, environment, and inspection goals.
Defect types commonly evaluated (application-dependent)
- Cross-threading
- Nicks / dents / handling damage
- Rolled or damaged thread crests
- Deformed or incomplete thread forms
Inspection logic options (scoped per application)
- Rule-based inspection with configurable thresholds
- Adaptive thresholding (to improve stability across normal variation)
- AI/ML classification (trained per customer application by SSI or by the customer, with validation using sample parts)
Data, logging & connectivity
Standard
- Pass/fail logging
- CSV export
Optional (scope-dependent)
- Image capture/storage (for fails and/or sampling)
- Database or MES hooks
- Fieldbus interfaces: EtherNet/IP, Modbus, OPC UA, EtherCAT
- PLC I/O handshakes with upstream/downstream equipment
What’s included vs optional
Typical included scope
- Mechanical provisions for the inspection zone and camera/lighting mounting
- Configured inspection routine tied to acceptance criteria
- Results outputs (pass/fail) and standard logging/CSV export
Common options
- Reject device integration and reject confirmation sensing
- Part tracking (encoder/sensors) when reject timing requires it
- Remote support options
- Image storage and advanced reporting
