The invention discloses a height sensor calibration method and device for an ultrasonic welding machine and electronic equipment. The method comprises the steps: measuring the calibration data of a first calibration block and the calibration data of a second calibration block under calibration pressure Pi; calculating to obtain each first calibration coefficient a (P1), a (Pi) and each second calibration coefficient b (Pi) by adopting a linear fitting mode according to the calibration data of the first calibration block and the second calibration block; taking calibration pressure Pi as a sampling point of an independent variable, taking a (Pi) as a corresponding dependent variable, calculating to obtain aa (P) and ba under any pressure by adopting the linear fitting mode, and obtaining a=aa(P)*P+ba; taking the calibration pressure Pi as a sampling point of an independent variable P, taking b(Pi) as a corresponding dependent variable, and calculating to obtain ab(P) and bb under any pressure by adopting a lin
