Abstract

Provided are an air knife assembly and a drying device, wherein the air knife assembly comprises two vertical and side-by-side air ducts (100); a gap is provided between the two air ducts (100) for allowing a circuit board (500) to pass through therefrom; at least one row of vent hole group distributed axially along the air ducts (100) is provided along an inner side of each air duct (100); each row of vent hole group of the two air ducts (100) is oppositely arranged; each vent hole group comprises a plurality of vent holes (101); and the vent holes (101) of the vent hole group located in the inner row are each alternately arranged along the axial direction of the air duct (100).

Description

technical field [0001] The invention relates to the field of circuit board electroplating, and more specifically relates to an air knife assembly and a drying device. Background technique [0002] The electroplating process of circuit boards involves multiple processes for surface treatment of circuit boards, such as spray cleaning, air drying, and electroplating. In the air-drying process, the circuit board needs to be dried by a drying device. The fan provides high-speed flowing air, and the air is sprayed by the air knife to dry the circuit board. The air knife assembly includes two air knives arranged side by side. An air nozzle is arranged on the air knife, which is conveyed by a transmission mechanism so that the circuit board passes between the air knife and the air nozzle sprays air to dry the circuit board. In order to avoid nozzle spraying, it is usually necessary to stagger the positions of the air nozzles, but it is easy to cause the uneven impact force of the a...
