Printing system and method for printing substrates

Abstract

The invention relates to a printing system (1) for printing substrates (8), in particular circuit boards, with a printing system (1) comprising at least one printing table (3) and a printing template (6) assigned to the printing table (3). A printing device (2) and having means (10) for aligning a substrate (8) on said printing table (3). The invention is designed such that the facility (10) has a first pair (11) comprising two first sliding elements (13, 14) displaceable towards each other along a first axis (22), and that two a second pair (12) of second sliding elements (15, 16) displaceable towards each other along a second axis (23) different from said first axis (22), wherein each pair (11) , 12) is equipped with at least one drive device (19) for simultaneously displacing the pair of sliding elements (13-16).

Description

technical field [0001] The invention relates to a printing system for printing substrates (Substrates, substrates), in particular circuit boards, with a printing device comprising at least one printing station and a printing template assigned to the printing station, and for printing substrates on the printing station A facility for alignment (Ausrichten, calibration). [0002] Furthermore, the invention relates to a method for operating the printing system described above. Background technique [0003] As is often used in modern printing systems for processing circuit boards, ceramic plates, solar cells, foils, etc., the substrates are successively fed into the printing unit by input means and are aligned, printed, and The principles that are subsequently exported work. For alignment, it is known to provide cameras for optical inspection of the substrate and image analysis systems to be able to optimally align the substrate with the printing template based on one or more ...

AI Technical Summary

Problems solved by technology

However, the optical detection of one or more substrates has the disadvantage that optical alignment marks have to be applied separately to the substrate and possibly also to the printing template

However, in the case of transparent substrate surfaces, it is not always possible to place optically detectable orientation marks

By providing orientation marks on the substrate, it also results that other components (such as circuit components, etc.) cannot be placed in the area of ​​one or more orientation marks, which limits the utilization of the surface of the substrate when printing
