Method for correcting position of machine head of spot drilling machine

The invention belongs to the technical field of point drilling machine correction, and provides a point drilling machine head position correction method, which corrects the positions of a plurality of suction nozzles on a head, and comprises the following steps: firstly, all suction nozzles on the head sequentially record the position coordinates of all suction nozzles through a position sensing module and a high-speed position latching unit on a processing station; and then the position coordinate of the first suction nozzle is taken as a reference, the processing unit calculates the position error of each suction nozzle and displays the position error on the display screen in real time, and the positioning error of a plurality of suction nozzles is obtained at one time. And then the position of a single over-limit suction nozzle is manually adjusted to traverse the positions of all over-limit suction nozzles. And finally, the position coordinates of the corrected suction nozzle can be repeatedly obtained an
