Abstract
本发明提供一种长条磁铁裂缝检测方法，涉及一种长条磁铁裂缝检测装置，该装置包括检测机构和光学放大平台；该方法包括以下步骤：S1：将多个长条磁铁置于围挡内，晃动载物台组件使其落入限位板的定位槽中，移除围挡并倒出多余长条磁铁；S2：推动联动板水平位移，通过小连杆同步带动压爪抵靠并相向挤压长条磁铁两端，使长条磁铁在弧形凹槽内弓起产生弯曲形变；S3：通过上盖板的曲面凸块观察长条磁铁上表面，同时调节凸面镜角度，经平面反射镜反射并放大长条磁铁下表面图像；S4：拨动限位爪解除对联动板的限位，在拉簧的作用下使联动板复位，压爪解除对长条磁铁两端的抵靠挤压，取下检测后的磁铁。本发明能够提高检测效率，保证产品质量。
