The invention discloses a cleaning net plate system for a full-automatic solder paste printing machine. The cleaning net plate system comprises lifting mechanisms and a cleaning mechanism; the cleaning mechanism is fixedly connected to movable parts of the lifting mechanisms, and the cleaning mechanism can ascend and descend along with the lifting mechanisms; the cleaning mechanism comprises a first cleaning assembly, a second cleaning assembly and movable mechanisms; the first cleaning assembly and the second cleaning assembly are arranged side by side, the movable mechanisms are fixedly connected to the lifting mechanisms which are arranged on the two sides of the first cleaning assembly and the second cleaning assembly respectively, and the first cleaning assembly and the second cleaning assembly can transversely move along with the movable mechanisms; and the movable mechanisms are used for being connected to a cross beam of the full-automatic solder paste printing machine, a firstvacuum groove is formed in the center of the first cleaning assembly, and a second vacuum groove is formed in the center of the second cleaning assembly. The cleaning net plate system has the advantages that screen holes and screen plate planes of the printing machine can be cleaned at the same time, the cleaning efficiency is high, the cleaning effect is good, further, automatic cleaning is achieved, and manpower is saved.
