20090125141 | WORKING APPARATUS AND WORKING METHOD FOR CIRCUIT BOARD - In estimating a curved surface model by approximating the shape of the board surface of a circuit board, auxiliary measurement spots are set other than measurement spots on the board surface, eligibility as a sampling displacement magnitude in estimating a curved surface model is determined according to a difference in a displacement magnitude from a work reference surface. When the sampling displacement magnitude is determined to be ineligible, a new measurement spot is reset. By this operation, a local increase and decrease in the displacement magnitude due to a discontinuity of the board surface exerts no influence on the estimation of the curved surface model, and the curved surface model approximated more closely to the shape of the actual board surface is estimated, leading to an improvement in the work quality with the working height adjusted to the proper height. | 05-14-2009 |

20120085253 | SCREEN PRINTING APPARATUS - A screen printing apparatus including two screen printers, each including a substrate introduction portion by which a substrate is introduced from an upstream side of a component mounting line, a printing portion which performs a screen printing to the introduced substrate, a substrate discharge portion by which the substrate is discharged to a downstream side, and a substrate moving stage which receives the substrate to position the substrate with respect to the printing portion and to move the substrate to the substrate discharge portion. The two substrate introduction portions, the two printing portions, and the two substrate discharge portions are arranged symmetrically to each other with respect to a perpendicular symmetrical plane extending in a transportation direction of the substrate in the component mounting line, respectively. Each printing portion is provided at a position further from the perpendicular symmetrical plane than the substrate discharge portion. | 04-12-2012 |
