Assembly Verification

The Problem

Assembly errors are expensive because they're invisible until they aren't. A missing fastener, wrong orientation, or skipped adhesive step becomes visible at test, at the customer, or after a field failure. The cost scales dramatically with how far downstream it travels. Manual verification through checklists and supervisor sign-off is incomplete — in high-mix environments, the cognitive load is too high for consistent human execution.

How Computer Vision Solves It

Computer vision at assembly stations verifies each step as it is completed — confirming the correct component, orientation, and positioning before the product advances. The system monitors the process in real time, step by step, creating a verification record for every unit. Missed or incorrect steps are flagged immediately when correction cost is minimal.

The Challenge with Current Solutions

High-mix environments require the model to know which variant is being assembled. Assembly steps are often partially occluded. Verification must return results before the next step begins — a two-second delay may be too slow. Process changes from new launches or engineering change orders require model updates.

What vfrog Brings That's Different

vfrog builds dedicated models for each assembly step and product variant, ensuring precise definitions of 'correct' for each check. Our agentic framework makes adding new steps or variants fast — describe the check, upload images, retrain. Edge deployment returns verification within cycle time. Edge cases are captured and fed back for continuous improvement.

Key Benefits

• Assembly errors caught at the step, not at final inspection
• Complete verification record for every unit produced
• Consistent checking across all operators, shifts, and variants
• Immediate alert on missed or incorrect steps
• Fast model updates to match process and product changes
• Reduced rework, warranty, and field failure costs
