Technical Field

The present invention relates to a vibrating device for vibrating a screen and a screen printing apparatus.

Background

Conventionally, there is a screen printing apparatus that vibrates a screen to print on a workpiece.

Patent document 1: japanese patent laid-open No. 63-199643.

Patent document 2: japanese patent laid-open No. 2005-238723.

Patent document 3: japanese patent laid-open No. 2010-221409.

Patent document 4: japanese patent laid-open No. 2009-126114.

In the screen printing apparatus, even if the screen is vibrated, the amount of the paste entering the holes of the screen may be uneven at the time of hole filling printing, and the holes may not be filled with the paste at a constant amount.

Disclosure of Invention

The technical scheme aims to provide the vibrating device which is difficult to cause uneven slurry amount entering the wire mesh holes.

The vibrating device of the present invention includes a screen plate, a vibrating unit configured to vibrate a plurality of opposing side surfaces on an outer side of the screen plate, and a controller configured to control vibration of the vibrating unit.

Effects of the invention

According to the present invention, the vibrating unit applies vibrations from a plurality of sides facing each other on the outer side of the printing material, whereby the screen plate is stably vibrated.
