Abstract (en)

[origin: WO9942228A1] A cleaning device (10) for removing residual material from a mold (12) having a molding surface (13) includes a robot (14) including an arm (16) movable in a plurality of degrees of freedom, the arm having a free end. A laser (18) is connected with the robot (14) and has an output end mounted to the arm (16) proximal to the free end so as to be positionable by the robot. An optical delivery system (38) includes a plurality of optical fibers, each fiber having a first end connected with the laser (18) and a second, output end attached to the free end of the arm of the robot (14). The output ends of the optical fibers (42) are aligned such that the laser forms a stripe of light (18b) on the molding surface (13). A controller (46) is connected with the robot (14) and is configured to direct the robotic arm (16) through at least one predetermined set of movements. A rotatable support (48, 54) is disposed proximal to the robot (14) the mold (12) being disposed on the support. The robot (14) positions the output end of the laser (18) with respect to the molding surface (13) to direct light (18a) from the laser to impinge on the surface and remove residual material from the surface as rotation of the support (48, 54) aligns different sections of the molding surface with the output end of the laser.
