Abstract

A cylindrical object surface testing device is provided, comprising an alignment unit and a circular conveyer, wherein the alignment unit arranges multiple cylindrical objects at a regular interval, the grip unit is configured to rotate at the same time of contacting with the alignment unit, successively receive well arranged cylinders and move the received cylinders along the circumference. In addition, the cylindrical object surface testing device comprises a plurality of grip units arranged around the circular conveyer with regular spacing and successively receiving cylinders photographing part which takes a photograph of the surface of the gripped multiple cylinders and a control unit configured to analyze the surface of the gripped multiple cylinders and determine whether the surface of the gripped multiple cylinders have defects.

Description

[0001] Related Application Cross Reference [0002] This application claims priority from Korean Patent Application No. 10-2011-0085510 filed on Aug. 26, 2011, the contents of which are incorporated herein by reference. technical field [0003] The invention relates to a device for inspecting the surface of a cylinder. Background technique [0004] Manufacturing nuclear fuel involves converting and enriching uranium ore concentrates, which are then made into ceramic forms about the size of a small fingernail, known as sintered uranium dioxide pellets (UO 2 pellets). Subsequently, hundreds of UO 2 The pellets are placed inside a metal tube and the metal tube is sealed to form a fuel rod. Thereafter, several hundred fuel rods are fastened to a solid metal structure to form a bundle of nuclear fuel rods. Typically, about 150 bundles of nuclear fuel rods are placed into a nuclear reactor in a nuclear power plant and participate in a fission chain reaction to generate heat. ...
