优选的：是， 在歩骤 101 之后， 可以把采集的各喷嘴 41和 /或激 光测距传感器的镜面 421的网片与各自的标准图片进行相似度对比， 得出表示相似度的值来作为对比结果 （步骤 102 ) 。
具体地， 可以通过图片处理单元使用相似度对比程序把图片釆 集单元采集的 喷嘴 41和 /或激光测距传感器的镜面 421的图片与 C]的标准图片进行相似度对比， 通过计箅得到相似度值。
优选的是， 在歩骤 102 之后， 可以通过園片处輝.单元根据在歩 骤 102中计算得到的相似度的值来判断喷嘴 41和 /或激光测距传感器 的镜面 421是否达到 ΤΗ常工作要求 （步骤 103 ) .
具体地， 图片处理单元把 102 歩骤得到的相似度值与预先设定 的满足工作要求的相似度值 k进行比较，如大于或等于 k则自动判定 为合格， 如果小于 k , 则判定为不合格， 从而由检测人员对相应的喷 嘴 41进行维修或吏换， 或者对相应的激光测距传感器的镜面 421进 行清洁。
上述是图片处理单兀自动进行 m似度对比， 并判断所检测对象 是否合格的情况。 当然， 实际检测过程屮， 也 ηί由检测人员以手动的 方式完成检测。 即， 在歩骤 1 02屮， 不是由图片处理单 自动进行对 比， 而是由检测人员直接通过观察图片釆集单 所釆集的各喷嘴 41 和 /或澂光测距传感器的镜面 421 的图片來判断其是否满足正常的工 作要求， 如不能满足正常的工作要求， 则对相应的喷嘴 41 或激光测 距传感器的镜而 421进行维护。或者也 以由检测人员调动相似度对 比禾里序进 j '对比从而判定是否合格，或者通过调整光 I ¾强度对某个被 检测对象重新采集图片，通过放大程序进行观察以确定是否达到正常 的工作要求。
本实施例的检测封框胶涂布设备的 法使得对封框胶涂布设备 的喷嘴成激光测距传感器镜面的检测更快更准确，并降低了操作人员 的劳动强度
本发明还提供了一种封框胶涂布设备， 其包括喷嘴、 ¾光测距 传感器以及根据本发明一个实施例的封框胶涂布设备的检测系统 本发明的封權胶涂布 «备由于除包括比如控制 元等已知结构 之外还包括上述检测系统， 因而功能更为完善， 也提卨了工作效率。
可以理解的是， 以上实施方式仅仅是为了说明本发明的原理而 采用的示例性实施方式， 然而本发明并不局限于此 对于本领域内的 普通技术人员而言， 在不脱离本发明的.精祌和实质的情况下， 可以做 出 种变型和改进， 这些变型和改进也视为本发明的保护范 1韦1
