Frequently Asked Questions
A machine vision systems integrator delivers a complete, production-ready solution by providing:
- Application feasibility and sampling plans
- Selection of cameras, lenses, lighting, and enclosures
- Mechanical design for mounts/guards and reject systems
- Controls integration (PLC, HMI, robotics, safety)
- Commissioning, validation, training, and ongoing support
The integrator’s job is to make the vision system work reliably in the real factory environment.
Use an integrator when you need:
- Multi-camera coverage or complex product geometry
- High-speed synchronization with motion and rejects
- Difficult materials (glossy, transparent, textured, variable)
- Data logging, traceability, and compliance workflows
- Custom handling/reject mechanisms and safety integration
Off-the-shelf sensors are great for simple checks; integrators shine when the problem is “messy.”
Generally:
- OEM: manufacturers standardized equipment or platforms
- Distributor: supplies components and offers limited application guidance
- Systems integrator: designs, builds, installs, and validates a complete working system on your line
Integrators bridge the gap between components and production reality.
Most integrators support industries with high-volume QA needs:
- Packaging, food & beverage
- Consumer products
- Pharma and medical devices
- Automotive and tier suppliers
- Electronics and precision assembly
A solid evaluation includes:
- Proven experience in similar inspections and environments
- Clear validation approach (sample plan, FAR/FRR targets)
- Strong controls/robotics capability if needed
- Support model (remote response, onsite options, spares strategy)
- Documentation quality and training plan
The best integrators help you define requirements before they sell you hardware.
Useful questions include:
- What are the major technical risks and how will you mitigate them?
- What defect set do you need to prove performance?
- How will changeovers and SKUs be handled?
- What do you guarantee (and what is excluded)?
- What will operators do when the system flags uncertainty?
Most integrators will want:
- Product drawings/specs and acceptance criteria
- Defect definitions with images or samples
- Line speed, spacing, and available station footprint
- Existing controls standards (PLC type, network protocols, safety rules)
- Environment info (washdown, vibration, dust, temperature)
- Data/traceability requirements (what to store and where)
Yes, EPIC Systems will do the following:
- Line walkthroughs to assess space, stability, lighting interference
- Capture of sample images under candidate lighting
- Proof-of-detectability testing for defects/codes
- Recommendations for fixturing, guarding, and reject handling
This step reduces surprises and aligns expectations early.
A well-run POC typically includes:
- Requirements & success criteria – Define defect types, acceptance thresholds, line speed, false reject/false accept targets, and any compliance needs.
- Sample collection – Gather representative “good” parts plus true defect samples (including borderline cases, multiple lots, and expected variation).
- Imaging feasibility – Test camera resolution, lenses, and—most importantly—lighting geometry to make the feature/defect consistently visible.
- Algorithm evaluation – Compare rule-based tools vs AI approaches, tune parameters, and verify robustness to normal variation (surface finish, print shift, glare, motion).
- Performance results – Document detection rates, FAR/FRR, confidence thresholds, and constraints (e.g., limits on line presentation, speed, or allowable variation).
- Deployment recommendations – Provide a proposed station concept (camera count/views, triggering/encoder needs, enclosure, reject method, data/logging plan).
At EPIC, we also have a dedicated Vision Lab that can support POCs by capturing sample imagery, testing lighting/optics strategies, and validating inspection approaches before a full production deployment.
Yes—retrofit is common and often high ROI. Typical retrofit scope includes:
- Mechanical mounting and guarding
- IO/network integration to existing PLC
- Product detection sensors and triggers/encoders
- Reject mechanism integration or addition (if not present)
- Commissioning without major downtime (planned cutover strategy)
Yes. At EPIC we provide complete “inspect + act” delivery:
- Air blast, pusher, gate, diverter, robot pick-off
- Reject confirmation sensors
- Reject bin capacity logic and lockouts
- Safe-state and fault handling
A reliable reject strategy is as important as the inspection itself.
A typical validation approach includes:
- Defined sample plan including edge cases
- FAR/FRR measurement with documented acceptance criteria
- Repeatability testing over time and shifts
- Measurement system analysis (MSA/GR&R) for gauging applications
- FAT/SAT execution with signed results
Good validation ensures the system performs reliably beyond day one.
Integration usually includes:
- Result handshakes and fault states to PLC
- Recipe selection tied to SKU and line mode
- Robot guidance calibration and coordinate transforms
- Alarm handling and safe interlocks
- Data sharing to MES/SCADA/historian
The goal is a seamless station that operators can run confidently.
A strong handoff typically includes:
- Operator training (normal use, changeovers, alarms)
- Maintenance training (cleaning, calibration checks, backups)
- Electrical schematics, mechanical drawings, network diagrams
- Troubleshooting guide and recommended spares
- Backup copies of system configuration and recipes
Commissioning typically includes:
- Installation verification and safety checks
- Lighting/optics tuning and camera calibration
- PLC/robot timing verification and reject validation
- Performance testing with representative samples
- Operator training and documentation handover
This ensures the system is stable, repeatable, and production-ready.
Common options include:
- Remote diagnostics and tuning assistance
- Onsite support for urgent issues
- Spare-part kits and quick-replacement procedures
- SLA response times for critical lines
- Periodic health checks and optimization reviews
Support planning is especially important for high-speed, high-volume lines.
