Abstract

The invention discloses a sliding type piezoelectric valve used for discharging particle-contained liquid. The sliding type piezoelectric valve comprises a valve system and a power system, wherein a liquid feeding pipeline is arranged in the valve body of the valve system; the lower end of the liquid feeding pipeline is provided with a syringe needle; the inner cavity liquid outlet of the liquid feeding pipeline is arranged by corresponding to the liquid inlet of a syringe needle infusion tube; a sliding block is arranged between the inner cavity liquid outlet of the liquid feeding pipeline and the liquid inlet of the syringe needle infusion tube; the sliding block is provided with a pipeline; the pipeline on the sliding block can correspond to the inner cavity liquid outlet of the liquid feeding pipeline and the liquid inlet of the syringe needle infusion tube; the right end of the sliding block is provided with a first push rod; the left end of the sliding block is provided with a second push rod; the sliding block is driven by the first push rod and the second push rod to slide in the left and right directions; the power system comprises a driving power supply, a piezoelectric stacker and a compression rod. The sliding type piezoelectric valve has the beneficial effects of high colloid adaptation, small noise, small abrasion, long service life, convenience in regulation and few regulation parameters, and the sliding type piezoelectric valve is a discharging device which does not damage tiny granular substances.

Description

technical field [0001] The invention relates to a piezoelectric valve, in particular to a sliding piezoelectric valve for discharging liquid containing particles. Background technique [0002] At present, particle-containing liquids are widely used in the production operations of electronic products, for example, solder paste containing solder particles, and conductive silver paste containing silver powder particles. Discharge devices for discharging and distributing particle-containing liquids to workpieces, various types of liquid discharge devices have been developed at home and abroad. The time-pressure liquid discharge device distributes by controlling the air pressure applied to the liquid and the action time. When distributing the glue with solid particles, the air pressure in the rubber cylinder has buffering properties, and the precision of the discharged liquid is low. The cut-off of the discharged liquid The force is poor, and the phenomenon of hanging drops and ...
