Abstract

The invention relates to an air knife assembly and a drying device. The air knife assembly comprises two vertical air pipes arranged side by side. A gap is reserved between the two air pipes, and a circuit board can pass through the gap. The inner side of each air pipe is provided with at least one line of air hole groups which are distributed in the axial direction of the air pipe. Each line of air hole groups of each air pipe are arranged on the inner side. Each air hole group comprises multiple air holes. The air holes of the lines of air hole groups on the inner sides of the air pipes are arranged alternately in the axial direction of the air pipes. The air holes are of hole-shaped structures in the air pipes, so that the circuit board cannot scrape against protruding objects, and the installation distance between the air pipes is shortened; when the air holes of the lines on the inner sides are arranged alternately, the two lines of air holes are protected against opposite impact, and therefore the air drying effect on the holes is improved; and air sprayed by the air holes of the two lines on the inner sides apply the same impact force on the circuit board, the circuit board can smoothly pass through the gap of the air knife assembly, the circuit board can be effectively prevented from swinging and colliding with the air pipes, and the air pipes are prevented from scraping against the circuit board.

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...
