Abstract

DISPOSITIVO DE MARCAJE POR LASER QUE COMPRENDE UN APARATO GALVANOMETRICO (1), EN CUYO EJE (2), SE FIJA UNA PIEZA MODULADOR (3) PROVISTA DE DOS ASPAS OSCILANTES GIRATORIAS, SOBRE LAS QUE INCIDE EL HAZ LASER (4), QUE RECORTADO POR LAS ASPAS (3), SE PROYECTA A TRAVES DE LA LENTE (5) SOBRE LA SUPERFICIE DEL MATERIAL (6), CON MARCADO DESDE UN TAMAÑO MAXIMO (7) HASTA UN TAMAÑO MINIMO, PASANDO POR VENTANAS DE PASO INTERMEDIAS (8), SIENDO IRRADIADA LA DISTRIBUCION DE LA POTENCIA (9), SOBRE EL MATERIAL, SIENDO (10) EL PERFIL GAUSIANO QUE CORRESPONDE A LA DISTRIBUCION DE POTENCIA DE RADIACION LASER SOBRE LA SUPERFICIE DEL MATERIAL SIN MODULAR, RECORTANDO EL HAZ, EL TAMAÑO MAXIMO (11), DE FORMA QUE LA DENSIDAD DE POTENCIA SOBRE EL MATERIAL (6) ESTE SIEMPRE POR ENCIMA DEL UMBRAL (13), DE AFECTACION DEL MATERIAL A LA RADIACION LASER, SIENDO (12) EL TAMAÑO DE HAZ PROYECTADO SOBRE EL MATERIAL EN FUNCION DE LA DENSIDAD OPTICA DE LA IMAGEN EN CADA PUNTO CORRESPONDIENTE. AL FINAL LA IMAGEN APARECE POR BARRIDO DE LOS ELEMENTOS LINEALES DE LA TRAMA OBTENIDOS.DEVICE FOR LASER MARKING INCLUDING A GALVANOMETRIC APPARATUS (1), IN WHICH AXIS (2), A MODULATING PIECE (3) FIXED WITH TWO ROTATING ROLLING BLADES, ON WHICH THE LASER BEAM IS INCIDATED (4), WHICH IS CUT BY THE BLADES (3), IT IS PROJECTED THROUGH THE LENS (5) ON THE SURFACE OF THE MATERIAL (6), MARKED FROM A MAXIMUM SIZE (7) TO A MINIMUM SIZE, PASSING THROUGH INTERMEDIATE PASS WINDOWS (8), BEING IRRADIATED THE DISTRIBUTION OF POWER (9), ON THE MATERIAL, BEING (10) THE GAUSIAN PROFILE THAT CORRESPONDS TO THE DISTRIBUTION OF LASER RADIATION POWER ON THE SURFACE OF THE UNMODULATED MATERIAL, CUTTING THE BEAM, THE MAXIMUM SIZE (11), SO THAT THE POWER DENSITY ON THE MATERIAL (6) IS ALWAYS ABOVE THE THRESHOLD (13), FROM THE AFFECTION OF THE MATERIAL TO LASER RADIATION, BEING (12) THE SIZE OF BEAM PROJECTED ON THE MATERIAL IN FUNCTION OF THE OPTICAL DENSITY OF THE IMAGE IN EACH CORRESPONDING POINT. AT THE END THE IMAGE APPEARS BY SWEEPING THE LINEAR ELEMENTS OF THE SCREEN OBTAINED.
