    • Methods are provided for etching, cutting and/or altering, the surface of a flower, plant, cut foliage, or foliage incorporated into consumable products such as cigars (hereinafter referred to as foliage, leaf, or product) with computer controlled laser energy to affect a desired artistic or utility design or marking on the foliage. The laser energy source is operative to provide an optical beam having power and optical wave length characteristics effective to thermally disrupt plant tissue to produce a permanent mark on the foliage surface or, alternatively, cut through the foliage. Additionally, methods are provided for the automatic transfer of leaves stacked in a container into the laser marking/cutting field and for depositing said leaves in a separate container after processing by laser. A method is described that provides for rapid, safe, and accurate manual placement of a leaf into a laser marking/cutting system. A method is provided for efficiently storing multiple designs in a database from which an individual design can be recalled by an operator and implemented by the system. A method for quality control of the process is provided through machine vision inspection of the leaf prior to and after laser processing. A method is included for providing designers with the hardware and software tools needed to develop new product designs and translate these designs into efficient formats for use by production equipment.
    • 提供了用计算机控制的激光能量蚀刻,切割和/或改变花,植物,切割叶子或结合到消费产品如雪茄(以下称为叶子,叶子或产品)中的叶子的表面的方法 影响叶子上所需的艺术或实用设计或标记。 激光能量源可操作地提供具有功率和光波长特征的光束,其有效地热破坏植物组织以在叶面上产生永久标记,或者切割通过叶子。 此外,提供了用于将堆叠在容器中的叶片自动转移到激光打标/切割领域中并且用于通过激光处理之后将所述叶子沉积在单独的容器中的方法。 描述了一种提供快速,安全和准确的将叶片手动放置到激光打标/切割系统中的方法。 提供了一种用于在数据库中有效地存储多个设计的方法,从数据库中可以由操作者召回个别设计并由系统实现。 通过在激光加工之前和之后的叶片的机器视觉检查来提供该方法的质量控制方法。 包括一种方法,为设计人员提供开发新产品设计所需的硬件和软件工具,并将这些设计转化为生产设备使用的有效格式。
