Resumen de: US2025243032A1
An inspection device for a layer material has a layer conveyor and a drive to pick up an anode or cathode layer by a pickup from a transfer location and bring it to a delivery location. The layer turner delivers a single anode or cathode layer from its pickup to a stacking table at the delivery location. The drive aligns the pickup and the stacking table relative to each other depending on a signal based on processing of a first or second image feed. A first image sensor is aligned between the transfer location and the delivery location to perform a first image feed when the pickup of the layer turner passes the first image sensor. A second image sensor is aligned between the transfer location and the delivery location to perform a second image feed when the pickup of the layer turner passes the second image sensor.
