| 摘要 |
The present invention provides a laser-drilling system comprising a) a laser device (21) that directs a pulsing laser beam at a firing zone (30); b) a solids handling assembly comprising: c) a first solids reservoir; d) a continuous solids indexer (69) comprising plural solids-receiving slots (68); e) a containment assembly comprising an undrilled-solids loading zone (66) and a drilled-solids delivery zone (32); f) a solids detector (60) in a first detection zone (29) between the loading zone (66) and the firing zone (30); and g) a color detector (61) in the first detection zone (29) to detect the color of the surface of a solid in a solids receiving slot (68); wherein: the indexer (69) transports a solid from the solids reservoir through a first detection zone (29) and then the firing zone (30) to a delivery zone (32), and the laser device (21), in synchronization with the solids indexer (69) and the solids detector (60), drills one or more holes or cavities in the surface of the solid; and the solids detector (60) detects the presence of a solid in a solids receiving slot (68) of the indexer (69) by means other than the pulsing laser beam of the laser device (21). |
