Description

Technical Field

[0001] This utility model belongs to the field of blueberry appearance inspection technology, and specifically relates to a vision-based blueberry appearance inspection device. Background Technology

[0002] Blueberries are a nutritious and uniquely flavorful berry, botanically belonging to the genus Vaccinium in the Ericaceae family. Their fruit is typically blue or purplish-black, covered with a white bloom, and widely enjoyed. Blueberry appearance inspection is a crucial step in ensuring blueberry quality, grading, and market value. It primarily involves observing the fruit's external shape, color, and integrity to determine if it meets commercial standards or has defects. Traditional blueberry appearance inspection methods suffer from stacking issues during transport, especially at the initial stage of the conveyor system when blueberries are introduced from the outside. This stacking prevents the bottom blueberries from being identified by the inspection equipment, leading to some substandard blueberries being transported to the qualified section undetected. Furthermore, the rotting fruit can negatively impact other healthy fruits being transported together.

[0003] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Utility Model Content
