Screws may become loose due to vibration or insufficient friction in the mating surface or both. If a screw is subjected to vibration constantly it is likely to work itself loose over time. If a screw is inserted into a substance that cannot provide sufficient friction, it will be loose.
Device for fastening screw onto workpiece and method of judging loosening of screw
ActiveUS20130067711A1Increase ratingsIncrease in load timeProgramme controlProgramme-controlled manipulatorEngineeringScrew loosening
In judging loosening of a crew, a measuring section measures a position of a bit as a relative position in relation to a placement surface of a screw supplying device when the screw is acquired from the screw supplying device. The measuring section also measures the position of the bit as a relative position in relation to a workpiece surface when fastening of the screw onto a workpiece has been completed. A judging section judges that screw loosening has not occurred when, based on the first and second bit positions, a difference between the first and second bit positions falls within an allowable range. The judging section judges that screw loosening has occurred when the difference does not fall within the allowable range.
