Abstract

The invention discloses a nozzle part for glue application, comprising a main shell. The main shell is a tubular body having one end closed, the inner surface of the closed end of the main shell is provided with a plurality of spray holes and protrusions, each protrusion is provided with a groove, and a spray hole is provided between every two adjacent protrusions; the open end of the main shell is connected to a nozzle, the grooves correspond to the corresponding spouts on the nozzle. The invention discloses a glue application apparatus. The tail end of each nozzle of the glue application apparatus is fitted with the nozzle part; the nozzle part is provided with grooves corresponding to the corresponding spouts of the nozzle, as well as spay holes adjoining the grooves; when glue is sprayed from the spouts of the nozzle to form ink drops, the glue enters and accumulates first in an opposite cavity and overflows to the adjoining spouts for spouting, and ink drops sprayed out by injecting pass through the nozzle part and turn into a continuous ink flow, and continuous ink supply is guaranteed for an application apparatus.

Description

technical field [0001] The invention relates to the technical field of gluing process, in particular to a nozzle accessory and gluing equipment for gluing. Background technique [0002] Glue-coating process is often used in the processing and production of the electronics industry, and the glue-coating process is also used in the process of electronic products such as semiconductors, displays, and touch screens. There are many gluing methods currently used, and the traditional gluing equipment mainly includes roll, slit, spin, and letterpress printing. [0003] With the development of cost saving in the electronics industry, some manufacturers have begun to use the inkjet method for the glue coating process. This process method has the characteristics of printing on demand, and can directly print out approximate graphics, and this method can also save materials. cost. However, because this gluing method relies on the nozzles on the nozzle for inkjet gluing, the ink droplet...
