TECHNICAL FIELD

[0001] The application relates to the technical field of glass detection, in particular to a mobile phone glass thickness detection machine with improved precision. BACKGROUND

[0002] With the iteration of smart phones towards "light and thin, special-shaped and multi-functional", the technical parameter requirements of mobile phone glass as a key structural part (cover glass, display screen glass, ultra-thin flexible glass UTG, etc.) are continuously strict. The technical innovation of the mobile phone glass thickness detection machine not only promotes the development of smart phones towards lighter and thinner and more complex structures, but also provides key detection support for emerging fields such as vehicle-mounted display, AR / VR, etc. Enterprises need to comprehensively consider the technical adaptability, production line compatibility and long-term maintenance cost when selecting, in order to realize the dual optimization of quality and efficiency.

[0003] Improving the precision of mobile phone glass thickness detection is a systematic project, which needs to be optimized in multiple dimensions such as equipment selection, environment control, calibration mechanism, process optimization and data processing. In particular, combined with the characteristics of mobile phone glass "ultra-thin (0.03mm-1mm), multi-layer (coating / adhesive layer / base material), special-shaped (curved / 2.5D)", the detection machine is required to meet high precision while realizing "real-time online detection" to avoid the production of batch defective products due to detection lag.

[0004] However, the above mobile phone glass thickness detection machine has the problems that the dynamic detection precision and speed are incompatible, the image acquisition of the optical imaging device needs a certain time and cannot completely capture the side view image of the fast-moving glass, and it is easily affected by the external environment and the operation is complex.
