Abstract:
A cleaning apparatus of a screen printer is provided to improve a cleaning function of a mask, by constituting a first and a second cleaning apparatus part for cleaning residue of a solder on the top/bottom of the mask. According to a cleaning apparatus of a screen printer cleaning residues of a cream solder provided to a mask, a first cleaning apparatus part(200) is comprised on the top of the mask, and removes the residues of the solder attached to a hole of the mask by exhausting air pressure and cleaning solution through the upper plane of the mask. A second cleaning apparatus(300) is comprised on the bottom of the mask, and absorbs the residues of the solder removed from the hole, as air pressure and cleaning solution of the first cleaning apparatus pass through the hole of the mask. A wiper apparatus part(400) removes the residue removed from the hole of the mask and the residue remained in the mask, by being installed on an outer surrounding of the first and the second cleaning apparatus part.
