装置のナツト検出装置。[Scope of Claim for Utility Model Registration] A weld nut is placed on a base material on a lower electrode, and welding is carried out by applying current to the base material and the weld nut while applying pressure between the lower electrode and an upper electrode that can move up and down. This is a device for detecting the presence or absence of a weld nut on a base material, which includes an upper electrode having a larger diameter than the weld nut to be welded, and a device that is movable up and down in proximity to the upper electrode and has one end. A detection lever is located directly below the tip surface of the upper electrode within a range that does not interfere with the weld nut, and is pushed down by the upper electrode when the upper electrode is pressurized with no weld nut on the base material. , ON and O depending on the vertical displacement of the detection lever.
A nut detection device for a weld nut welding device, comprising: a contact type switch that operates as an FF.
