Online Measurement ILM Series
Non-contact 3D line laser + contact displacement sensor — automotive lighting 100% online inspection
Online 100% Inspection System
Full dimensional measurement for headlamps, taillight A/B, light bars. Gap/Flush 100% inspection with correlation to traditional gages & CMM. Non-contact (preferred) and contact (supplemental) available.
Non-Contact 3D Line Laser Measurement
Preferred Solution — Fast, Flexible, Zero Damage
3D Line Laser Scanning
Emits laser line, captures deformed fringe pattern, generates 3D point cloud via triangulation. Hundreds to thousands of 3D points per scan.
Non-Contact Non-Destructive
No mechanical contact — avoids part damage. Suitable for glossy or chrome surfaces. Zero scratch risk, low maintenance.
High Flexibility Multi-Product
Measurement points can be added/deleted/densified anytime during production. Simple fixtures — positioning only, low cost.

Contact Displacement Sensor Measurement
Supplemental Solution — for optical blind spots & high-precision scenarios
Point Probing Principle
Retractable probe contacts surface, linear encoder measures displacement, outputs single-point height. Stable, reliable accuracy.
High-Precision Measurement
±0.03mm repeatability, correlation 80% points ＜0.1mm. Fast acquisition for high-precision scenarios.
Application
Optical blind spot coverage (deep holes, transparent materials), offline lab sampling, robot-loaded lines.

Technology Selection Recommendations
Preferred: Fully deploy non-contact online measurement for all standard lamp inspection needs.
Hybrid condition: Only add contact measurement when there are clear optical blind spots at critical locations.
Implementation by scenario: Manual loading → non-contact online measurement preferred; robot loading → contact online measurement preferred.
Supplier Collaboration: Establish strategic partnerships for custom 3D devices to gain tailored technical support & priority service.
