Automatic rapid pipette tip placing device

The invention discloses an automatic rapid pipette tip placing device, and belongs to the field of experimental equipment. According to the scheme, a limiting plate in a pipette tip clamping mechanism is matched with a telescopic spring to clamp and fix a pipette tip falling from a storage hole, so that manual operation and pollution are reduced; a flexible clamping piece is driven by an electric telescopic rod and a gun head storage mechanism to clamp and limit the gun head, and a magnetic repulsion binding mechanism drives a movable clamping plate to clamp the gun head by virtue of magnetic repulsion between a first magnet block and a second magnet block, so that rapid placement is realized, time and labor are saved, and the experiment efficiency is improved; meanwhile, the placement control terminal detects whether the gun heads are polluted or not through a pollution detection module, interference to experiment results is reduced, experiment precision is improved, the gun heads are cyclically placed in co
