The Challenge
T-Erre manufactures high-precision diesel motors with complex multi-step assembly. Each motor has 200+ components that must be placed, oriented, and torqued correctly. Manual assembly relies on operator experience and paper checklists—prone to errors that reach customers.
Assembly Complexity at T-Erre
🔧
Multiple Sub-Assemblies — Cylinder blocks, crankshafts, valve trains, fuel systems assembled separately then integrated
📋
High Precision Required — Component tolerances ±0.1mm, torque specs ±5% for engine reliability
⚠️
Manual Inspection Risk — Operators miss orientation errors, miscounted fasteners, misalignment until test run
PIQAPART monitors each assembly step in real-time. At every checkpoint, AI vision verifies component presence, position, and orientation. Operator gets instant OK (green) or NG (red) feedback. No surprises at test-run.
Live Assembly Monitoring in Action
PIQAPART verifies component placement and orientation step-by-step. AI detects misalignment immediately. Operator receives real-time OK/NG feedback.
Industrial assembly workflow with PIQAPART monitoring. Each step verified, each component accounted for. Zero errors reach test.
PIQAPART Step-by-Step Process
1
Capture Assembly Frame
Camera captures current assembly state from fixed angle at each workstation.
Can PIQAPART handle multiple assembly variants (different models)?▼
Yes. PIQAPART is trained on multiple motor variants. Operator selects model at start of assembly. AI adapts verification rules accordingly. T-Erre runs 5 different motor models on same line.
How fast is the AI feedback?▼
0.5 seconds from step completion to operator feedback. Operator completes assembly step → camera captures → AI processes → green/red light triggers. No line slowdown.
What if AI says “NG” but operator disagrees?▼
Supervisor can override with password. Override is logged (who, when, why). AI learns from overrides. False positive rate drops after each override correction.
Does PIQAPART check torque values?▼
PIQAPART monitors fastener visual presence and positioning. For torque verification, integrate with smart torque wrenches (wireless connection). Combined system gives 100% assembly verification.
How is the data used for continuous improvement?▼
Dashboard shows: which steps most error-prone, which operators need coaching, failure pattern analysis. T-Erre used this to improve workstation design, reducing errors by an additional 40%.
What’s the training time for operators?▼
30 minutes hands-on introduction. Most operators master system in one shift. AI feedback is intuitive (green/red light). After day 2, operators prefer PIQAPART to manual assembly.
