Surface jet printing method and equipment for magnetic part

A surface jet printing method of a magnetic piece comprises the steps that a magnetic attraction piece and the magnetic pole direction of the magnetic attraction piece are determined; a plurality of magnetic pieces with the same size are magnetically attracted on the same plane and are arranged in an array to form a rectangular magnetic piece group; jet printing is carried out on the upper end face of the magnetic piece set at the position column by column or row through a jet printing piece; the magnetic piece set is turned over by 180 degrees so that the bottom face of the magnetic piece set can face upwards; the second first magnetic piece and the magnetic attraction piece are close to each other and attract each other to determine a second area of the magnetic piece set; and a jet printing piece is used for jet printing the upper end face of the magnetic piece set at the position column by column or row. The invention further discloses surface jet printing equipment for the magnetic part. According to the
