Description
technical field [0001] The invention relates to the field of dispensing technology, in particular to a volumetric valve device for dispensing and dispensing equipment provided with it. Background technique [0002] Glue dispensing is a process of dripping colloid on the product, so that the product can play the role of sticking, potting, insulating, fixing, etc. As the dispensing equipment in the dispensing process, the dispensing valve usually extrudes the glue from the dispensing needle on the dispensing valve through air pressure. This dispensing method is affected by the stability of the air pressure, which is prone to unstable glue output. The amount of glue is difficult to accurately control and other problems. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the object of the present invention is to provide a volumetric valve device for dispensing and a ...
