Abstract

The invention provides a nozzle which includes a nozzle channel and a fluid channel. The nozzle channel is provided with an air flow inlet and an outlet; the fluid channel is provided with a fluid channel inlet and a fluid channel outlet, wherein the fluid channel inlet is in communication with a fluid source to enable fluid to enter the fluid channel, the fluid channel outlet communicates with the nozzle channel so that the fluid can enter the nozzle channel, and the fluid in the nozzle channel can be pressed out of the outlet through the air flow applied from the air flow inlet. The nozzle can distribute viscous fluid of small volume and blockage is less prone to occurring.

Description

technical field [0001] The present application relates to a nozzle, especially a nozzle used in the field of electronic processing. Background technique [0002] With the continuous thinning and miniaturization of electronic products, the requirements for the printing process of circuit boards are also getting higher and higher. There is therefore a need for more sophisticated apparatus for dispensing process material for dispensing very small volumes of circuit board process material. Some processing materials are viscous fluids, such as solder paste, resin, etc. One way to distribute this viscous fluid is to set up a cavity, which communicates with the nozzle. The cavity contains fluid, and the piston reciprocates to squeeze the fluid in the cavity, so that the fluid is extruded from the outlet of the nozzle. . Due to the poor fluidity of the viscous fluid, this solution for distributing the fluid has certain defects, such as low distribution efficiency, difficult contr...
