AI Technical Summary
Existing technologies cannot efficiently and accurately detect defects on all six sides of a laptop touchpad, and are difficult to adapt to different types and sizes of products, resulting in low detection efficiency, low accuracy, and the inability to automatically obtain product model information and perform sorting.
The product is transferred using a jig displacement module. The first and second camera modules work together with a flipping mechanism to perform multi-faceted inspection using multi-directional light sources and a bottom backlight. The product model is obtained through a barcode scanning module, enabling accurate multi-faceted inspection.
It enables precise multi-faceted inspection of laptop touchpads, improving inspection efficiency and accuracy, reducing labor costs, and adapting to the needs of products of different models and sizes.
