<p>A laser processing unit (10) includes a workpiece loading station (30). A laser workstation (32) includes a laser robot (90) operable to perform a laser operation on a workpiece (W2). A track (12, 14) extends from the loading station (30) through the workstation (32). A first stationary wall section (40) separates the workstation from the loading station at a proximal side of the workstation. A second stationary wall section (50) is offset from the first stationary wall section at a distal side. A first movable wall section (60) forms a laser light-tight seal with the first stationary wall section. A second movable wall section (70) forms a laser light-tight seal with the second stationary wall section. A shuttle (20) is operable to move along the track (12; 14) to deliver the workpiece (W^ W2) from the loading station (30) to the workstation (32). The movable wall sections are supported by the shuttle and move concurrently with the shuttle and the workpiece, as the workpiece is delivered to the workstation.</p> |
