INTERNAL ELECTRODE INSERTION DEVICE FOR WELDING EQUIPMENT FOR SKELETON OF NUCLEAR FUEL ASSEMBLY

WIPO Patent Application WO/2021/241792

A1

The present invention relates to an internal electrode insertion device for automatically transferring multiple internal electrodes to a welding position in welding equipment for the skeleton of a nuclear fuel assembly and, more specifically, to an internal electrode insertion device for transferring internal electrodes to a welding position in order to weld the skeleton of a nuclear fuel assembly. The internal electrode insertion device comprises: a table (110); multiple internal electrode bars (120) including internal electrodes (121a) (121b) and arranged parallel to each other in multiple rows above the table (110); a guide member (130) provided at the table (110) so as to guide the horizontal movement of the internal electrode bars (120); guide rails (140) arranged on the table (110) in a direction parallel to the direction of alignment of the internal electrode bars (120); a driving unit (150) to which the rear ends of the internal electrode bars (120) are fixed and which includes a servo motor (151) horizontally driven along the guide rails (140); and a control unit (200) for controlling driving of the servo motor (151) such that positions of the internal electrodes, predetermined according to input types of fuel for the nuclear fuel assembly, are reflected in the driving.
