粘贴有光学基准标记的光学编码器所用的度盘组件
摘要：
将柔性光学标记应用于光学度盘基板，以为光学位置编码器制作光学度盘组件。所述标记可以是极限标记、索引标记或其它类型的标记。所述标记基板可以是塑料薄膜(如聚酯)，所述标记具有一个表面上的微结构图案，所述表面被反射性金属涂层所覆盖，该标记还具有粘结层，用于将标记贴附于光学度盘基板上。在该标记被贴附固定后，使用与标记分离的手柄部分来操作该标记。该标记对于柔性度盘基板(如金属带基板)尤其有用。将标记贴附于度盘基板是制作编码器度盘的分离步骤，通过该步骤可实现诸如减少存货、降低成本和缩短交付期等多项好处。
摘要（英）：

A flexible optical marker is applied to an optical scale substrate to make an optical scale assembly for an optical position encoder. The marker may be a limit marker, index marker, or other type of marker. The marker substrate may be a plastic film such as polyester, singulated from a 'recombine' roll created by a web process. The marker has a microstructured pattern on one surface that is covered with a reflective metal coating. The marker also has an adhesive layer and is affixed to the optical scale substrate by a process of aligning the marker to an edge of the scale and then applying pressure to the upper surface of the marker. The marker may be applied with a handle portion that is separated from the marker after the marker is affixed. The marker may be especially useful with a flexible scale substrate such as a metal tape substrate. By affixing the marker to the scale substrate as a separate step of making an encoder scale, various benefits such as reduced inventory, cost, and lead time may be achieved.
