Embodiment Construction

[0026] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0027] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", horizontal" etc. are based on th...

Abstract

The invention belongs to the technical field of piezoelectric injection valves, and specifically relates to a non-impact piezoelectric injection dispensing valve, which includes a valve body, a valve seat and a push rod, the valve body is fixedly connected to the valve seat, and a nozzle is installed at the bottom of the valve seat. There is a first liquid storage chamber inside the valve seat, and a piezoelectric drive mechanism is arranged in the valve body. The liquid storage cavity forms a clearance fit, and a first flow channel is arranged inside the ejector rod, and the first liquid storage cavity, the first flow channel and the second liquid storage cavity communicate with each other. Compared with the prior art, the present invention adopts a non-collision method for dispensing, replaces the striker by the ejector pin, avoids the collision and wear of the nozzle and the striker, improves the accuracy and efficiency of dispensing, saves a lot of maintenance costs, and enhances The service life of the device is extended, the injection of glue containing solid particles is realized, the phenomenon of local heating of the device is reduced, and the phenomenon of glue leakage is prevented.

Description

technical field [0001] The invention belongs to the technical field of piezoelectric injection valves, in particular to a non-impact piezoelectric injection dispensing valve. Background technique [0002] Piezoelectric injection valves use the characteristics of piezoelectric materials to generate mechanical force through voltage to control the opening and closing of the valve. Because the space for opening and closing the valve is very small, the piezoelectric action frequency is extremely high, and it can inject a very small amount of water at high speed. Therefore, piezoelectric injection valves are widely used in the field of high-precision, high-reliability dispensing. [0003] At present, the piezoelectric jet dispensing valve in the industry is generally equipped with a striker, which generates high-frequency vibration under the action of the piezoelectric actuator and amplifier, and then uses the striker to hit the nozzle to realize the injection of glue. However, i...
