Abstract:
1. A device for conveying a material through a treatment station where the material is subjected to a laser treatment capable of leaving contamination residues on the device, the device comprising: a conveyor including a structure having a first surface for conveying the material and a second opposing surface, the conveyor being configured to follow a closed loop trajectory wherein the material is received on the first surface upstream of the treatment station and removed downstream of the treatment station, the structure having openings extending from the first surface to the second surface; a first brushing station positioned to brush the first surface of the conveyor after the material has been removed; a washing station including nozzles positioned adjacent the second surface of the structure and configured to project a washing liquid through the openings in the structure from the second surface to the first surface after the surface has passed through the first brushing station and a suctioning structure positioned adjacent the first surface of the conveyor for removing the washing liquid from the conveyor, the suctioning structure having an open mouth portion configured to support the conveyor; a first drying station including at least one blowing element configured for directing a flow of drying aeriform substance at the first surface after the first surface has passed through the washing station, the suctioning structure of the washing station being sized and positioned such that residues and/or washing liquid removed in the drying station by the flow of drying aeriform substance is directed into the open mouth portion of the suctioning structure; and a second brushing station positioned to brush the first surface of the conveyor after the surface has passed through the washing station, the washing station being positioned intermediate the first and second brushing stations.
