Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA EL CONTROL CORRECTO FISICO DE LA FRECUENCIA Y DEL SUMINISTRO DE POTENCIA DE UN GENERADOR DIGITAL, ESPECIALMENTE PARA UN PROCESO DE SOLDADURA DE ULTRASONIDOS, ASI COMO UNA REDUCCION DEL COSTE EN UNA ELABORACION DE ACUERDO CON LAS CONDICIONES NECESARIAS DEL CONVERTIDOR DE ULTRASONIDOS, DEL TRANSFORMADOR DE AMPLITUD Y DEL SONOTRODO. EL PROCEDIMIENTO, QUE SE REALIZA POR MEDIO DE UNA UNIDAD DE CONTROL DIGITAL, COMPENSA NO SOLAMENTE LA DISPERSION DE LA FRECUENCIA DE RESONANCIA A TRAVES DE UNA ZONA AMPLIA, SINO TAMBIEN EN LA SITUACION Y DESPLAZAMIENTO DEL PUNTO DE RESONANCIA DURANTE EL PROCESO DE SOLDADURA DEBIDO A LAS MODIFICACIONES DE PRESION Y DE TEMPERATURA QUE DEBEN SER REGULADAS. LAS OSCILACIONES DE POTENCIA, ORIGINADAS MEDIANTE OSCILACIONES DE LA TENSION DE ABASTECIMIENTO O DE LA PRESION, SE COMPENSAN Y SE RECONOCEN POR MEDIO DE SOFTWARE. EL SOFTWARE REGISTRA EL DESARROLLO COMPLETO DE LA MAQUINA INLINE, ADAPTA SUS PARAMETROS Y SUPERVISA EL CICLO COMPLETO. EL DESARROLLO DE LOS PROCESOS INDIVIDUALES, COMO: RECONOCIMIENTO DE LOS PARAMETROS DEL SISTEMA DEL CONVERTIDOR EN DESARROLLO EN VACIO, RECONOCIMIENTO DE LOS PARAMETROS BAJO PRESION, CON LA MENOR ENERGIA POSIBLE PARA LA CONDUCCION DE LOS COMPONENTES ACUSTICOS Y ELECTRONICOS, RECONOCIMIENTO DE LA TENDENCIA DE LOS PRINCIPALES PARAMETROS DEL SISTEMA Y CUANDO SE SOBREPASAN LOS VALORES LIMITES DADOS PREVIAMENTE, SE EFECTUA POR MEDIO DEL SOFTWARE. EL SOFTWARE DETERMINA AUTOMATICAMENTE LOS PARAMETROS DE REGULACION Y DE CONTROL CORRECTOS FISICAMENTE Y GARANTIZAN POR ELLO UN RENDIMIENTO OPTIMO EN LA TRANSFORMACION DE LA ENERGIA ELECTRICA EN ENERGIA DE ULTRASONIDOS. COMO CONSECUENCIA SE PROTEGE LA ETAPA DE SALIDA DE SITUACION DE TENSION DEBIDO A CORRIENTE REACTIVA ALTA. LAS PROPIEDADES ANTES MENCIONADAS SE REDUCEN NO SOLAMENTE EN EL COSTE DE LA ELABORACION DE SISTEMA ACUSTICOS, SINO TAMBIEN DESCIENDEN LOS COSTES DEBIDO A UNA SEGURIDAD DE FUNCIONAMIENTO ELEVADA.
