In actual production, LCD screens are cut into different shapes according to design requirements, as well as during cleaning, transportation, and other processes, which can easily cause defects such as cracks, shells, broken edges, and corners at the edges. These defects are generally very small, and the cutting edges are easily affected by uneven lighting, grayscale gradients, and cutting shapes, making edge defect detection difficult. Defects may cause LCD screen breakage and electrode damage during subsequent production and use, which will become quality hazards. It is necessary to promptly remove defective products through testing equipment to avoid them flowing into downstream processes and wasting material and labor hours.

The LCD screen edge inspection machine developed and produced by Fuxin Optoelectronics based on machine vision and AI artificial intelligence technology integrates light, machine, electricity, software, and algorithms. It is mainly used for automatic detection of edge defects in the LCD screen production process, achieving machine replacement.
