| titleOfInvention | Pellet inspection apparatus |
| abstract | Apparatus for inspecting nuclear fuel pellets for diameter, surface flaws, length and weight. The apparatus includes, in an array, a pellet pick-up station (121), four pellet inspection (127, 129, 131, 133) stations and a pellet sorting (137) station. The pellets (P) are delivered one at atimetothe pick-up station by a vibrating bowl through a vibrating linear conveyor (165). A pellet gripper (135) is associated with each successive pair of the stations and operates to pick up each pellet at the back or pick-up station (121) of the pair and to deposit the pellets at the forward or deposit station of the pair. The grippers (135, 515, 517, 519, 521, 523) reciprocate together between their respective pick-up stations and deposit stations but the gripper jaws are opened selectively depending on the state of the pellets at the stations and the particular cycle in which the apparatus is operating. Inspection for diameter, flaws and length is effected in each case by a laser beam projected on the pellets by a precise optical system. The pellets are exposed to the inspecting beam on a seat between rotating rollers which rotates the pellet through one revolution for each inspection. A separate roller stand including a drive for the rollers is provided at each of the three optical inspection stations. Each laser and its optical system are mounted in a container (791) which is free standing on a precise surface and is provided with locating buttons which engage locating surfaces in the surface so that the laser and optical system is precisely set. The roller stands are likewise free standing in a precise surface and are provided with locating buttons which engage locating seats in the surface so that the pellets are precisely positioned in their seats. The diameter optical system (127) projects a thin beam of light which scans across the top of each pellet. The beam is projected on a measuring diode array. The flaw optical system (129) projects a thin beam of light which scans across the pellet unflawed parts of the surface reflects the light to a measuring photodiode; flawed areas diffuse the light and reflect the image of the light spot in the flaw away from the photodiode. A part of this scan beam also scans a grating producing pulses so that the parts of the surface being scanned can be coordinated with the scanning. In each case the scanning is synchronized with the rotation of the rollers which define the seat. The length optical system (131) projects a sheet of light across the length of the pellet producing a shadow which is projected on a measuring diode array. |
