Abstract: A lens inspection module comprises: a lens insertion station, at least one lens inspection station, and a lens removal station as well as a closed-loop transportation rail, a cuvette transportation shuttle with a plurality of inspection cuvettes, and a self-driving cleaning shuttle for cleaning the rail. Cleaning shuttle comprises a driving unit a cleaning head, a suction unit, and a tube connecting cleaning head and suction unit. Cleaning head is spaced apart from suction unit and driving unit in the transportation direction and is pivotally arranged about a pivot axis. Cleaning head may comprise a distance sensor for detecting the distance between cleaning shuttle and transportation shuttle. Driving unit is configured to change the speed of the self-driving cleaning shuttle when the distance between the cleaning shuttle and the transportation shuttle is shorter than a predetermined threshold distance.
