A special-shaped dispensing needle with constant rotation center

Abstract

The invention discloses an irregularly shaped dispensing syringe needle with a constant rotation center and relates to the field of dispensing equipment. The irregularly shaped dispensing syringe needle comprises a needle base and a needle tube; the needle base comprises a storage part, a transition part and a connecting part which are fixedly connected with one another in turn from top to bottom;storage chambers are arranged in the storage part and the transition part; the needle tube comprises a vertical tube, a first bent part, a connecting tube, a second bent part and a discharging tube which are connected end to end in turn and are all equipped with through holes in corresponding interiors; the vertical tube is fixedly connected with the bottom of the connecting part; the through hole of the vertical tube is connected with a duct; a space included angle of the vertical tube and the connecting tube is at 135 degrees, under the effect of connecting and reversing of the first bent part; the space included angle of the discharging tube and the vertical tube is at 45 degrees, under the effect of connecting and reversing of the second bent part; the tail end of the discharging tubeand the vertical tube are located on a same axis. The irregularly shaped dispensing syringe needle with the constant rotation center has an excellent processing effect for various irregular products,such as thicker products or products of different shapes (such as circular and rhombus frames), and has an effect quicker and better than that of a present vertical syringe needle.

Description

technical field [0001] The invention relates to the field of dispensing equipment, in particular to a special-shaped dispensing needle with a constant rotation center. Background technique [0002] For liquid crystal screens of smart devices such as mobile phones and tablet computers, it is usually necessary to use dispensing steps for production synthesis; however, in some special structures, such as side walls or dispensing in narrow gaps, in vehicle parts, vehicle The dispensing of the place where the thickness is relatively large in the iron frame of the product, the dispensing of the frame, the dispensing of special-shaped products, etc., the ordinary vertical dispensing needle cannot be directly used for dispensing, and manual gluing is often required; In the dispensing needle designed in the patent application number CN201610364377.4, although the ordinary vertical dispensing needle on the market is improved, the dispensing needle can more conveniently dispens irregul...
