Measuring method and device for dispensing head position control in dispensing process of quartz crystal resonator

According to the measuring method for controlling the position of the dispensing head in the dispensing process of the quartz crystal resonator, a used quartz crystal resonator dispensing machine comprises a horizontally-arranged rotating table, and a plurality of carriers used for carrying a base and a wafer are evenly distributed in the circumferential direction of a wheel disc. A base loading station, a first dispensing station, a wafer loading and picking station, a second dispensing station and an unloading station are sequentially arranged along the circumference of the wheel disc; the dispensing station is provided with a dispensing machine; the wafer loading and picking station is used for picking the base subjected to the first dispensing, unloading waste products and loading wafers on qualified products; one high-speed contour scanner is arranged between every two adjacent stations, and the accurate contour of the surface of the carrier is obtained for dispensing, wafer loading and unloading, so tha
