Abstract

The invention discloses a nozzle used for a printed circuit board cleaning machine. The nozzle comprises a high-pressure water duct, wherein the high-pressure water duct is fixedly connected with a spraying arm, two sides of the spraying arm are provided with a plurality of screw holes, nozzles are screwed into the screw holes; two sides of the outer end part of the nozzle are provided with assembling platforms, a V-shaped slot is formed in the surface of one or multiple or even all assembling platforms, and a water outlet hole is formed in the middle of the bottom of the V-shaped slot. According to the invention, nozzles are arranged at the left side and the right side of a same plane of the spraying arm, so as to achieve water spraying in upward direction and downward direction, and circuits arranged at the upper and lower sides can be cleaned. The nozzles and the spraying arm are combined and connected in a screwed manner, and therefore, the nozzles disclosed by the invention has the characteristics of being simple in structure, easy to install and convenient to change.

Description

technical field [0001] The invention relates to a nozzle for a printed circuit board cleaning machine. Background technique [0002] In the circuit board welding and assembly technology in the electronics industry, after the components on the circuit board are processed through various welding processes, due to the influence of flux, solder and the environment, a certain amount of residue remains on the pins of the components on the board. , these residues directly affect the quality of the product, and must be cleaned to ensure the electrical performance indicators of the circuit board and finally to ensure the stability, reliability and working life of the electronic product. Therefore, cleaning the circuit board assembly is a very important task. Important and highly technical work. [0003] Due to the shortcomings of ethanol scrubbing or ultrasonic cleaning, such as poor cleaning effect and large damage to the circuit board, the cleaning of circuit board components is c...
