Abstract

UN PROCESO PARA ENSAMBLAR DOS LAMINAS DE PLASTICO (4,5) A LO LARGO DE UNA LINEA DE UNION (10), A TRAVES DE UNA HOJA DE PAPEL (7,8) SUPERPUESTA A UNA PRIMERA LAMINA DE PLASTICO (5) DE LAS ANTEDICHAS QUE CONSISTE EN: A) COLOCAR LAS DOS LAMINAS DE PLASTICO (4,5) CON LA HOJA DE PAPEL SUPERPUESTA (7,8) ENTRE UN ELEMENTO DE YUNQUE EN CONTACTO CON LA SEGUNDA LAMINA DE PLASTICO (4) Y UN ELEMENTO ABOCINADO ACCIONADO ULTRASONICAMENTE EN CONTACTO CON LA HOJA DE PAPEL (7,8), EN DONDE DICHO ELEMENTO DE YUNQUE TIENE UNA SUPERFICIE ESTRIADA Y DICHO ELEMENTO ABOCINADO TIENE UNA SUPERFICIE PLANA;, B) EJERCER UNA PRESION DE ENTRE 0,2 Y 2,0 BARAS EN LAS LAMINAS DE PLASTICO (4,5) Y DE PAPEL (7,8) QUE SE ENCUENTRAN ENTRE EL ELEMENTO DE YUNQUE Y EL ELEMENTO ABOCINADO Y C) ACTIVAR EL ELEMENTO ABOCINADO CON ULTRASONIDOS CON UNA POTENCIA DE ALIMENTACION DE AL MENOS 1,2 KW DURANTE UN PERIODO DE TIEMPO DE ENSAMBLAJE DE ENTRE 80 Y 300 MILISEGUNDOS PARA ENSAMBLAR LAS DOS LAMINAS DE PLASTICO (4,5) A LO LARGO DE LA LINEADE UNION DESEADA (10) Y LOS ARTICULOS OBTENIDOS SEGUN EL MISMO.
