The invention discloses an automatic safety valve filter screen installation device which comprises a filter screen material distribution mechanism. The filter screen material distribution mechanism comprises a material distribution guide groove, a material distribution block and a material distribution power piece. A material supply guide groove is formed in the right side of the material distribution guide groove. A clamping groove is formed in the side, right opposite to the material supply guide groove, of the material distribution block. The automatic safety valve filter screen installation device further comprises a filter screen clamping mechanism capable of clamping a filter screen in the material distribution guide groove and installing the filter screen in a safety valve. The filter screen clamping mechanism comprises a clamping jaw mechanism and a mechanical hand. In work, the material distribution power piece drives the material distribution block to be located at the rear end of the material distribution guide groove, the clamping groove of the material distribution block is right opposite to the material supply guide groove, the filter screen enters the clamping groove of the material distribution block through the material supply guide groove, the material distribution power piece drives the material distribution block to move forwards along the material distribution guide groove, the material distribution block pushes the filter screen to the front end of the material distribution guide groove through the clamping groove, the filter screen in the material distribution guide groove is clamped and installed in the safety valve through the filter screen clamping mechanism, and the whole filter screen installation work is finished. The automatic safety valve filter screen installation device can be used for replacing manual operation, work stability is good, the assembling cost is low, and work efficiency is improved.
