Problems solved by technology

[0003] Most of the injection dispensing devices on the market or the research of scholars today use the structure of the striker nozzle. The striker moves at a high speed and hits the nozzle, so that the liquid at the nozzle forms a local high pressure and then is ejected through the nozzle. The striker type jet dispensing device is in When spraying glue with solid particles (such as conductive silver paste), the solid particles in the glue will be destroyed, resulting in changes in the liquid material, and even clogging the nozzle after accumulation

Abstract

The invention relates to the technical field of jetting glue-dispensing devices and particularly relates to a self-limiting impact type jetting glue-dispensing device. The self-limiting impact type jetting glue-dispensing device comprises a valve body with a cavity and a glue supplying base with a jetting cavity, wherein a push rod is arranged in the cavity, and a driver for driving the push rod is arranged in the cavity; a glue inlet and a glue outlet are formed in the jetting cavity of the glue supplying base, an impact rod is arranged above the glue outlet, is mounted in the jetting cavity in a sliding manner by virtue of a limiting nut and is driven by the push rod, and the limit impact position of the impact rod is limited by the limiting nut. When the self-limiting impact type jetting glue-dispensing device is used for jetting glue, the impact rod does not directly collide with a nozzle but collides with the limiting nut, so that particles are not crushed under the impact of the impact rod when liquid with the particles is jet.

Description

technical field [0001] The invention relates to a self-limiting impact type glue dispensing device, which belongs to the technical field of glue dispensing devices. Background technique [0002] Fluid dispensing, the process of precisely dispensing fluids in a controlled manner, is a key technology in the electronics packaging industry. The traditional contact dispensing technology relies on the dispensing needle to adhere the glue to the substrate. This technology needs to accurately control the height of the needle drop and lift, and the dispensing speed is slow, and the repeatability of the glue point is poor. With the miniaturization, high integration and high density of electronic products, the traditional contact dispensing can no longer meet the current technology market. Compared with the contact dispensing method, the non-contact jet dispensing technology has the advantages of fast dispensing speed. , small liquid dot size, high glue dot consistency, strong operati...
