The working principle of the using method of the invention is as follows:

when the suction nozzle 2 needs to descend and the lamp beads 20 generate an adsorption effect, as part of the filter shaft 3 extends out of the bottom end of the suction nozzle 2, the filter pad 34 is firstly contacted with the top end of the lamp beads 20, then in the continuous downward movement process of the suction nozzle 2, the filter shaft 3 is pushed and moves upwards relative to the suction nozzle 2, so that the filter membrane 33 in the filter assembly is vertically stretched, the whole size of the filter assembly is increased, in the process, the filter block 31 moves from the bottom end position of the cavity 21 to the top end position of the cavity 21, the magnetic force sensor receives the change of the movement position of the filter block 31, the change of the distance between the suction nozzle 2 and the lamp beads 20 can be monitored in real time, thereby ensuring that the suction nozzle 2 moves down to the top end of the lamp beads 20 accurately and adsorbs the lamp beads 20, preventing the suction nozzle 2 from excessively moving downwards to impact the lamp beads 20 to damage the lamp beads 20, effectively realizing buffer protection of the suction nozzle 2 on the lamp beads 20, and at the same time, the filter block 31 continuously moves upwards to gradually reduce the distance between the filter block 31 and the movable block 42, due to the magnetic repulsion effect between the filter block 31 and the movable block 42, the movable rod 41 which is originally vertically arranged is effectively pushed to rotate towards the inner wall of the suction nozzle 2, the space in the movable part 4 is reduced, so that air in the movable part 4 penetrates into the vertical hole 5 from the outlet pipe 51 and is then discharged downwards obliquely through the inclined hole 53, dust attached to the top end of the lamp bead 20 is timely blown away before the lamp bead 20 is completely covered by the suction nozzle 2, the possibility that the dust enters the suction nozzle 2 is reduced, the normal use of the suction nozzle 2 is avoided, when the bottom end of the suction nozzle 2 is completely contacted with the lamp bead 20, the vacuum connector 22 and the vacuum shunt 23 are started to effectively suck the air in the suction nozzle 2, the suction nozzle 20 is adsorbed by the suction nozzle 2, the lamp bead 20 is controlled to be transferred by using a chip mounter, when the lamp bead 20 is placed on a PCB substrate, the vacuum connector 22 and the vacuum splitter 23 release air to promote the suction nozzle 2 to release the suction of the lamp bead 20 and prepare for the suction nozzle 2 to suck the next lamp bead 20;

because the limiting strip 6 has the extrusion effect on the fixing piece 7 when the suction nozzle 2 is completely contacted with the lamp beads 20, part of the fixing piece 7 is compressed into the lower groove, the liquid in the fixing piece 7 is transferred into the corresponding moving piece 9 through the communication hole 8, the moving piece 9 is effectively pushed to move outwards to be in a stretching state, when the suction nozzle 2 releases the lamp beads 20 and continuously moves upwards, the filter shaft 3 is pushed to move downwards relative to the suction nozzle 2 under the action of the tension spring in the filter assembly, in the process, when the moving piece 9 moves downwards to the position of the limiting strip 6 and is clamped with the limiting groove 61, the moving piece 9 falls along the track of the limiting groove 61 due to the fact that the filter shaft 3 drives the moving piece 9 to continuously move downwards, so that the moving piece 9 is compressed towards the direction of the filter shaft 3 when moving piece 9 moves downwards to the bottom end of the limiting strip 6, the liquid in the moving piece 9 is effectively pushed to be transferred into the fixing piece 7, the fixing piece 7 is expanded and stretched to prepare for stretching the next moving piece 9, meanwhile, the moving piece 9 is influenced by the spiral limiting groove 61 to drive the filter shaft 3 to rotate for a certain angle, the filter shaft 3 is effectively driven to drive the filter assembly to generate torsional vibration for a certain angle, after the moving piece 9 is separated from the limiting strip 6, the filter shaft 3 is influenced by the tensile force of the filter membrane 33 to reversely rotate to restore the original state, the filter assembly is fully vibrated to timely clean dust on the filter assembly, the normal use of the suction nozzle 2 is further ensured, and in addition, four times of contact with the limiting strip 6 can be generated in the continuous downward movement process of the filter shaft 3, so that the descending speed of the filter shaft 3 is effectively reduced, the upward movement speed of the filter shaft 3 is ensured to be smaller than that of the suction nozzle 2, and the protection effect on the lamp beads 20 is further improved.
