3D cameras for mobile phone middle frame sidewall inspection

Overview

3D cameras for mobile phone middle frame sidewall inspection

Inspection of clips and screws on the narrow sidewalls of smartphone middle frames.
Conventional imaging systems often struggle with incomplete data due to restricted access, component occlusion, and multi-reflection on metallic surfaces. Sizector® 3D cameras utilize advanced hardware-based computational imaging to deliver high-precision point clouds in real-time.

Challenges in high-precision sidewall inspection

Restricted imaging access: Narrow gaps and deep positions cause data occlusion.

Metallic interreflection: Reflective surfaces lead to artifacts and incomplete point clouds.

High-throughput requirements: Large data volumes often limit the inspection cycle time.

Hardware features for optimized data quality

Partition projection, a must facing interreflection

The integrated zoned projection technology targets specific inspection areas, preventing light interference and ensuring point cloud integrity on reflective metal.

Hardware ROI selection for maximum frame rates

On-board Region of Interest (ROI) cropping reduces data transmission requirements, significantly increasing acquisition speed for high-speed production.

Integrated prism setup for optimized imaging angles

The use of optical prisms overcomes physical occlusion in narrow spaces, ensuring a complete 3D topography of clips and screw holes.

An obvious contrast

Hardware-level processing for rapid integration

Sizector® 3D cameras (S028, S162, SX, and M series) handle image acquisition, point cloud reconstruction, and data processing entirely on-board. This hardware-based architecture reduces the load on the host PC and simplifies secondary development, leading to shorter project cycles and lower system complexity.
