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

June 14, 2024

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

Smartphone curved glass panels are integral to modern phone designs, offering functional benefits such as better ergonomics and immersive displays. A curved glass panel is processed by hot pressing bending. After processing, the whole curved surface will have a certain deformation. Mastering the deformation state and deformation trend of the curved surface is the key to adjusting the process parameters and speeding up the production process.

Pain Points of Smartphone Curved Glass Panel Inspection

Inspecting curved glass panels is challenging due to their small size, thinness, and curvature. Traditional tools like calipers struggle to provide accurate data. In addition, the panels are easily deformed under pressure. Contact measurement methods, such as CMM, introduce errors and are inefficient for high-volume production environments.

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.
