Embodiment Construction

[0055] figure 1 Shown is a schematic perspective view of a screen printing machine 100 according to the invention having at least one screen 120, at least one squeegee 110 for aligning the squeegee 110 relative to the screen 120 along with the screen 120 at least one squeegee driver 130 for parallel X-axis X-translation and at least one computer device 140 for controlling the screen printing machine 100 .

[0056] For this purpose, the computer device 140 can communicate with the rest of the screen printing machine 100 in a wireless or wired manner. This communication link is not shown for clarity.

[0057] The scraper drive 130 comprises for example four electric motors 130A, 130B, 130C, 130D, in particular servo motors. For example, two electric motors 130A, 130C are used to vertically translate the scraper 110 along the Z-axis Z, another electric motor 130B is used to rotate the scraper 110 about the Y-axis Y and another electric motor 130D is used to make the scraper 110...

Abstract

The invention relates to a computer-implemented method for controlling a screen printing machine, comprising the following steps: fixing a substrate on a printing plate of a screen printing machine; automatically printing a printing paste with the squeegee of the screen printing machine through the silk screen of the screen printing machine for generating a printed pattern on the substrate after fixing, wherein a computer device of the screen printing machine pulls the squeegee with a squeegee driver of the screen printing machine at a squeegee speed along the X-axis over the silk screen; determining a deviation of an actual dimension of the printed pattern along the X-axis from an corresponding theoretical dimension of the printed pattern during printing or after printing; calculating at least one plate speed of the printing plate to compensate for the deviation by the computer device; and shifting the printing plate with the plate driver at the at least one plate speed along the X-axis by the computer device during printing or during a further printing. The invention also relates to a screen printing machine for carrying out the method.

Description

technical field [0001] The invention relates to a method for controlling a screen printing machine, comprising securing a substrate on a printing plate, screen printing a printing paste by means of a squeegee to produce a printed pattern on the substrate and during printing relative to the screen. The screen moves the printing plate to compensate for deviations in the actual dimensions of the printed pattern from the theoretical dimensions of the printed pattern. [0002] The invention also relates to a screen printing machine for carrying out the method, the screen printing machine comprising at least one squeegee drive for translating the squeegee of the screen printing machine relative to the screen of the screen printing machine and for Plate drive for plate translation of screen printing machines. Background technique [0003] In known screen printing machines, the screen is stretched in the direction of movement of the squeegee due to the friction between the squeegee...
