Abstract

Se proporcionan metodos y aparatos para separar secciones de molde, retirar un producto de lente de las secciones de molde separadas y transferir el producto de lente a una bandeja de procesamiento e incluyen poner en contacto las secciones de molde ensambladas con un fluido caliente, para romper porciones fundidas entre las secciones de molde y utilizar uno mas elementos en forma de cuna para separar y desprender la secciones de molde entre si. Se emplea una cabeza de vacio que tiene multiples compuertas de vacio, para desprender el producto de lente recientemente moldeado de una seccion de molde y para liberar el lente de la cabeza de vacio a una bandeja de procesamiento. Un cilindro con aire en circulacion dirigido alrededor de la circunferencia del lente, es efectivo para mantener el lente en la posicion desdoblada conforme lente se libera en la bandeja de procesamiento. Se proporciona un conjunto de bandejas incluyendo multiples bandejas que sostienen multiples lentes, e incluye caracteristicas para permitir distincion visual y/o mecanica de las bandejas y los lentes de esta manera sostenidos.
