Internal electrode insertion device for welding equipment for skeleton of nuclear fuel assembly

An internal electrode insertion device for welding equipment for a skeleton of a nuclear fuel assembly, wherein the internal electrode insertion device is for transferring internal electrodes to a welding position in order to weld the skeleton of a nuclear fuel assembly, the device comprising:

• an insertion table;
• a plurality of internal electrode bars disposed in parallel in a plurality of rows on a top portion of the insertion table, each of the internal electrode bars being provided with each of the internal electrodes therein;
• guide members provided on the insertion table and configured to guide a horizontal movement of the internal electrode bars;
• guide rails provided in parallel with an alignment direction of the internal electrode bars on the top portion of the insertion table;
• a driving unit fixed to rear ends of the internal electrode bars and having a servomotor provided thereon, thereby performing horizontal movement driving along the guide rails;
• and
• a control unit for controlling driving of the servomotor based on a preset position of each of the internal electrodes based on a fuel type of the nuclear fuel assembly.
