In a gas sensor assembling apparatus configured to integrate first and second gas sensor components, a posture adjustment part configured to adjust the posture of a first member in a horizontal plane adjusts the posture of the first member to an insertion possible posture determined in advance while holding the first member having been transferred from a conveyance mechanism at a posture adjustment position fixedly determined in advance, and transfers the first member in the insertion possible posture to the conveyance mechanism while maintaining at the posture adjustment position, the conveyance mechanism conveys, to an integration position, the first member in the insertion possible posture, and at the integration position, the first member and the second member are integrated with each other by inserting a sensor element of a second member into an insertion port of the first member in the insertion possible posture.

Gas sensor assembling apparatus and assembling method

A method of manufacturing a gas sensor includes a step of preparing an assembly including a sensor element, a metal cylindrical body through which the sensor element penetrates in an axial direction, and a protection cover that is attached to the cylindrical body and that covers one end side of the sensor element. The method also includes steps of arranging a coil in a periphery of at least a portion of the cylindrical body at the same side as the other end of the sensor element with respect to the protection cover to avoid the protection cover of the assembly, induction heating the portion of the cylindrical body where the coil is arranged in the periphery by applying current to the coil, and hence removing oil adhering to the portion.

A method for assembling a gas sensor includes fitting through holes of annular mounting parts with an element dummy disposed vertically and whose cross-sectional shape perpendicular is similar to that of a sensor element. The annular mounting parts are a plurality of parts including a ceramic powder compact. A tubular body is fitted with outer peripheries of the annular mounting parts, and then, the element is abuttingly disposed on an upper end of the dummy. Subsequently, the dummy is moved vertically downward to fit the through holes of the annular mounting parts with the element, thereby obtaining a workpiece. The workpiece is vertically inverted, and with the element tip being in contact with a sealing assist jig that has a buffer performance, the upper end of the uppermost annular mounting part is pressed vertically downward to compress the powder compact, thereby sealing an inside of the tubular body.
