Liquid sprayer

Abstract

The liquid sprayer for cleaning, development, etching and other wet process includes a casing with hollow compartment, several conveying pipes set to the compartment vertically, several nozzles below the pipes a connector to drive the conveying pipes for spraying liquid toward the same direction, a driver to drive the connector to move in different direction, a horizontal pedestal inside the compartment for setting substrate.

Description

technical field [0001] The present invention relates to a liquid spraying device, in particular to a multi-directional liquid spraying device used in wet manufacturing processes such as cleaning, developing or etching. Background technique [0002] Liquid spraying devices are widely used in various industrial wet fabrication processes, such as cleaning, developing, or etching processes. The existing liquid spraying device in the wet production process includes a housing containing liquid spraying equipment, a liquid supply system containing a plurality of water supply pipes and a plurality of nozzles arranged on the lower side thereof, and a conveying line for transporting the substrate sprayed by the liquid, A driving device is used to drive the spraying movement. With the complexity and diversification of the substrate design, the single-direction spraying liquid spraying device may not be able to efficiently complete the wet fabrication process of the substrate. How to ...

Since each water supply pipe 22 rotates alternately clockwise and counterclockwise with its rotating shaft as the center and in the direction of the arrow 28, there will often be leakage at the joint 23 between the water supply pipe 22 and the main pipe 21. This is the existing liquid Another disadvantage of sprinkler 10
