Nuclear fuel pellet appearance surface defect online inspection system

Abstract

The invention discloses an online inspection system for nuclear fuel pellet appearance surface defects. The feeding device comprises: a feeding guide groove in butt joint with a previous procedure production line; a peripheral surface detection guide groove, a double-row belt conveying mechanism and a discharging guide groove, which are sequentially in butt joint behind the feeding guide groove; afeeding and pushing mechanism which is arranged corresponding to the feeding guide groove; a circumferential surface detection assembly and a diameter detection assembly which are arranged corresponding to the circumferential surface detection guide groove; an end surface detection assembly which is arranged corresponding to the double-row belt conveying mechanism; and a discharging and pushing mechanism which is arranged corresponding to the discharging guide groove. According to the invention, the guide groove and the transmission mechanism are directly butted with the production line; synchronous operation of the detection system and the production line is realized; meanwhile, the circumferential surface detection assembly, the diameter detection assembly and the end surface detectionassembly are arranged to comprehensively detect the nuclear fuel pellets passing through the transmission line one by one, slope transmission is ingeniously utilized to achieve the purpose of end surface detection, and comprehensive appearance defect detection of the nuclear fuel pellets and integration of butt joint of the nuclear fuel pellets and a production line are achieved.

Description

technical field [0001] The invention relates to the technical field of pellet appearance inspection, and relates to an online inspection system for appearance surface defects of nuclear fuel pellets. Background technique [0002] The nuclear fuel pellet is the core part of the nuclear fuel element, generally a small cylindrical block. After the nuclear fuel pellets are made, they will be ground first to remove burrs and other surface excess materials, and then their surface conditions need to be inspected to avoid appearance defects such as lack of materials, excess materials, and cracks in subsequent use. Unforeseen accident. Due to the small size of the nuclear fuel pellet itself, it is very inconvenient to detect it individually. Therefore, it is an effective detection method to detect it through automated equipment, but it is difficult to comprehensively detect its appearance at one time on the assembly line equipment. How to connect with the production line of nuclear...
