Apparatus is disclosed in a system for drilling holes with a laser beam in a plurality of discrete moving workpieces carried by a support which moves each workpiece sequentially along a predetermined path at a predetermined velocity, the apparatus including means for sequentially tracking along a portion of such path each workpiece being drilled seriatim by the laser beam. This tracing apparatus includes means for directing the laser beam generally transversely of the direction of movement of the workpiece on the support and a mirror for folding the transversely directed laser beam toward the workpieces with means for oscillating the folding mirror synchronously with the movement of the workpiece to track the workpiece as it moves.

A system for drilling holes with a laser beam in a plurality of discrete moving workpieces comprising a support which moves said plurality of discrete workpieces sequentially along a predetermined path at a predetermined velocity, and apparatus for sequentially tracking along a portion of such path

A system for drilling holes with a laser beam in a plurality of discrete moving workpieces comprising a support which moves said plurality of discrete workpieces sequentially along a predetermined path at a predetermined velocity, and apparatus for sequentially tracking along a portion of such path each said workpiece being drilled seriatum by said laser beam, said tracking apparatus comprising means for directing said laser beam generally transversely of the direction of movement of said workpiece on said support; a mirror for folding said transversely directed laser beam toward said workpiece on said support; and means for oscillating said beam folding mirror synchronously with the movement of said workpiece, said mirror being oscillated between a first position directing said laser beam at a preselected point on the surface of said workpiece facing said folding mirror when said workpiece is at a location corresponding to the beginning of said path portion, and a second position directing said laser beam at the same said workpiece point when said workpiece is at a location corresponding to the termination of said path portion, whereby, during the portion of the mirror oscillation from the first position to the second position the laser beam is caused to track the preselected point on each workpiece; and a focusing lens positioned between said oscillating beam folding mirror and said workpiece for focusing said laser beam upon said workpiece surface and maintaining that focus throughout the tracking of said workpiece by said laser beam.
