Mechanical arm position alignment method and device and electronic equipment

The invention discloses a mechanical arm position alignment method and device, a medium and electronic equipment, and relates to the field of mechanical arms. And the movement accuracy of the mechanical arm can be improved. The mechanical arm position alignment method comprises the steps that initial position information of a target plane for a mechanical arm is determined, wherein the initial position information comprises a unit normal vector and a preset projection point of the target plane; controlling the mechanical arm to move according to the initial position information of the target plane; the current coordinate of the tail end plane of the mechanical arm is obtained, and a target projection point and a target normal vector on the tail end plane are determined according to the current coordinate; determining the displacement between the tail end plane and the target plane according to a target projection point and a target normal vector on the tail end plane, and a unit normal vector and a preset pro
