S110、提供一辊轴表面检测装置，包括基板10、安装在基板10一端的检测旋转机构20、夹持驱动机构30、光源40、以及安装在基板另一端的摄像组件50。检测旋转组件20包括旋转驱动机22及连接旋转驱动机22的滚轴23。夹持驱动机构30包括升降驱动组件31及连接升降驱动组件31的二夹持件32。摄像组件50包括摄像头52。检测旋转机构20、夹持驱动机构30、光源40及摄像组件50均与一控制器连接。
S120、启动旋转驱动机22使得滚轴23处于旋转状态，同时启动光源40及摄像组件50；
S130、将辊轴100的两端分别活动卡设在二夹持件32上，启动升降驱动组件31，驱使辊轴100下落与滚轴23相切接触，滚轴23通过摩擦力带动辊轴100从动旋转；
S140、调节摄像头52的角度位置，保证摄像头52、滚轴23和辊轴100之间的切线及光源40中心在同一平面上；
S150、当有光源40的光线从滚轴23和辊轴100之间的间隙射出时，摄像头52进行摄像捕抓；
S160、控制器通过漏光的光亮度程度及光线的漏光位置进行数据处理，分析出辊轴100表面的状态；当辊轴100下落与滚轴23相切接触时，保证辊轴100不挤压滚轴23至变形。
本发明的辊轴表面检测装置利用摄像头对滚轴与辊轴之间的间隙进行摄像成像，根据成像的漏光光亮度程度及光线的漏光位置分析出辊轴表面的状态，自动化程度高，减少了人工，检测效率高且检测结果准确性高。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
