ABSTRACT:
An apparatus for inspecting samples that may include a curvature that varies from sample to sample comprises a scanning element, a feed mechanism, and a pivot mechanism. The scanning element transmits and receives a signal to and from the sample as the sample passes by, thereby building an image or profile of the sample. The feed mechanism includes a drive motor coupled to a series of pulleys and belts that form an open-ended chain. The pulleys rotate when driven by the drive motor and are coupled to an array of rollers that rotate as well to propel a inspection sample past the scanning element. The pivot mechanism includes a series of primary and secondary links that also form an open-ended chain. The primary links are coupled to the rollers and the combination pivots in unison to form an arc that matches the curvature of the sample in order to maintain a fixed distance between the sample and the scanning element.
