Abstract

The invention relates to a position matching method for a screen printing device and a screen printing device. The screen pringting device includes a mask sheet (25), a movable printing stage (3), a camera head (40) having a mask recognition camera (41) and a substrate recognition camera (42), and a controller for controlling them. The controller executes mark recognition of the substrate (W) by using the substrate recognition camera (42). The camera head (40) is driven / controlled so as to execute mask recognition of the mask sheet (25) periodically by using the recognition camera (41) while the same mask sheet is used. Moreover, according to the latest mask position information acquired by the mark recognition of the mask sheet (25) and the substrate position information, the controller obtains a correction amount based on the position shift between the mask sheet (25) and the substrate (W) and drives / controls the printing state (3) according to the correction amount so as to mount the substrate (W) on the mask sheet (25).

Description

technical field [0001] The present invention relates to a screen printing device for printing paste such as paste solder and conductive paste on a substrate. Background technique [0002] Conventionally, there is known a printing apparatus in which a substrate (printed wiring board) placed on a printing table is superposed on a stencil, and a paste such as solder paste or conductive paste supplied on the stencil is pressed by a squeegee. Here, the paste is applied (printed) to predetermined positions on the substrate through openings formed in the template. [0003] In this type of printing apparatus, for example, as described in Japanese Patent Publication No. 2682145, an upward-facing stencil recognition camera is installed on a movable printing table supporting a substrate, and the stencil recognition camera is used to take pictures of the stencils placed on the stencil. For marking, a substrate recognition camera facing downward is fixedly installed on the apparatus fra...
