Abstract

The invention discloses a screen printer and a contraposition method for the same. The screen printer comprises a screen printer body; the screen printer body is provided with a computer and an XYtheta platform, wherein the computer is electrically connected with the XYtheta platform and can drive the XYtheta platform to move in the X-axis direction, the Y-axis direction and the theta-axis direction; a to-be-printed product placing part is arranged on the upper side of the XYtheta platform; the screen printer body further comprises a light source, a bracket and at least two CCD cameras, wherein the light source is arranged in the XYtheta platform; a light transmitting hole is formed on the edge of the to-be-printed product placing part on the XYtheta platform; the CCD cameras are mounted on the bracket; the camera shots of the two CCD cameras just face the light transmitting hole to enable light emitted by the light source to transmit the light transmission hole to reach the camera shots of the two CCD cameras; and signal output ends of the two CCD cameras are electrically connected with the computer. The two CCD cameras are adopted to conduct the contraposition. The screen printer has the advantages of simple structure, easiness in manufacturing, high contraposition speed and accuracy in contraposition.
