Enhancing Precision in Smartphone Glass Panel Inspection with OptimScan 5M Plus

Smartphone glass panel inspection requires precise methods due to the panels' small size and delicate structure. However, the methods of calipers and coordinate-measuring machines (CMM) fail to provide the necessary accuracy. SHINING 3D's OptimScan 5M Plus desktop 3D scanner offers a non-contact, high-precision, and high-efficiency solution for inspection needs.

Understanding Smartphone Curved Glass Panels

 Curved glass panels are integral to modern smartphone designs, offering functional benefits such as improved ergonomics and immersive displays. These panels are processed through hot pressing bending, which inevitably introduces deformation across the entire curved surface. Understanding both the deformation state and deformation trends is essential for adjusting process parameters and accelerating production. 

Pain Points of Smartphone Curved Glass Panel Inspection

Inspecting curved glass panels presents several challenges due to their small size, thinness, and curvature. Traditional tools, like calipers, struggle to provide accurate data, while the panels are prone to deformation under pressure. Contact measurement methods, such as CMM, introduce additional errors and are inefficient in high-volume production environments.

3D Scanning - Get Complete 3D data in Less Than One Minute

OptimScan 5M Plus

SSHINING 3D's OptimScan 5M Plus addresses the limitations of calipers and CMMs by acquiring 3D data in a non-contact manner, eliminating the risk of panel distortion.

Key features include:

• High accuracy and repeatability: up to 0.005 mm, ensuring stable results.

• Fast scanning: single scanning time ≤1.5 seconds; with an automatic rotary table, three-dimensional data can be captured efficiently in less than one minute.

• High-resolution imaging: 1080P optical system with 5 million industrial cameras captures complete and smooth data.

3D Inspection - Auto Output Inspection Report within 1 Minute

After completing the first inspection path programming (about 10 minutes), we will import the 3D scanning data into the inspection software. Within 1 minute, the inspection software can automatically output the inspection report and generate the chromatogram, which intuitively shows the deformation location and accurately analyzes the curvature of the surrounding curves, and so on.
