SQUEEGEE POSITION AUTOMATIC CORRECTION MECHANISM AND SQUEEGEE POSITION AUTOMATIC CORRECTION METHOD FOR SCREEN PRINTER

摘要

PROBLEM TO BE SOLVED: To provide a squeegee position automatic correction mechanism and a squeegee position automatic correction method for a screen printer which can easily keep a horizontal position constant at a squeegee tip and obtain sufficient printing accuracy.SOLUTION: A screen printer equipped with a screen plate 11 and a squeegee 20 has: an angular adjustment instrument that adjusts an angle of the squeegee 20; a laser displacement gauge 15 that can measure a first distance that is a horizontal distance of the tip of the squeegee 20 in a condition that the squeegee 20 is vertically suspended and a second distance that is a horizontal distance of the tip of the squeegee 20 in a condition that the squeegee 20 is tilted to an attack angle that is a predetermined included angle between the top face of the screen plate 11 and the squeegee 20; and squeegee driving means 12 that horizontally moves the squeegee 20 to a printing start position in a condition of being tiled to the attack angle on the basis of a distance difference between the first distance and the second distance.
