A jet dispensing valve and dispensing method thereof, the jet dispensing valve comprising a cylinder (200), a plunger component (201), a cavity (300), a nozzle component (400), an electromagnetic valve (700) and a fixing plate (800); the cylinder (200) and the cavity (300) are fixedly connected; the nozzle component (400) is disposed at the lower end of the cavity (300); one end of the plunger component (201) is located inside the cylinder (200), and the other end is disposed inside the cavity (300) and contacts the nozzle component (400); the electromagnetic valve (700) is fixedly connected to the cylinder (200) via the fixing plate (800); the jet dispensing valve further comprises a vent component (600) disposed at one side of the cylinder (200); the cylinder (200) further comprises a vent groove and a vent through-hole (209); the vent groove is a ring groove structure, and is disposed at the side of the cylinder (200) connected to the fixing plate (800), and communicates with the vent opening of the electromagnetic valve (700) through a tubing of the fixing plate (800); the vent through-hole (209) is disposed inside the cylinder (200); and one end of the vent through-hole (209) communicates with the vent groove, and the other end communicates with the vent component (600). The vent component (600) is disposed to reduce noise and improve working environment; and a guide device is disposed to avoid the radial displacement of the plunger component (201) in the up-and-down movement.
Description
technical field [0001] The invention belongs to the technical field of fluid control, and in particular relates to a jet dispensing valve and a dispensing method thereof. Background technique [0002] In the packaging process of industrial products, the use of injection valves has become more and more extensive. The injection valve sprays a small amount of high-viscosity fluid (flux, conductive glue, epoxy resin and adhesive, etc.) to the appropriate position of the workpiece (chip, electronic component, etc.) to achieve mechanical or electrical connections between components. The size of the injection flow depends on factors such as nozzle diameter, fluid pressure, fluid viscosity or injection pressure. Existing injection valves on the market are usually made up of nozzle, striker, feeding part, cylinder and high-speed solenoid valve, etc. The striker and cylinder piston are integrated and reset by spring. When the injection valve is working, the striker and the cylinder ...
