Description

Technical Field

[0002] Circuit board is a common circuit component, mainly made of copper clad laminate, copper foil, prepreg, chemical solution, anode copper, dry film, ink, etc. During the production and processing of circuit boards, dust and dirt are easily accumulated on their surfaces. Before installing electronic components on the circuit boards, the dirt on the circuit boards needs to be cleaned.

[0003] According to the patent number CN 214052824 U, a circuit board cleaning device is disclosed, which includes a water supply device, a water storage tank, a water pipe, a water reservoir, a nozzle, a supporting device, etc. The used water is recycled through a collection pool, and the height of the nozzle is adjusted by setting a cylinder to drive the telescopic column to move up and down to meet different flushing requirements. The circuit board is driven to rotate by a motor so that it can automatically flip over for double-sided flushing. However, when the device cleans the circuit board, it is necessary to complete multiple processes such as installing, cleaning, flipping, cleaning, and removing the circuit board. The steps need to be repeated when cleaning the next circuit board. The whole process is time-consuming and the cleaning efficiency is very low. Moreover, the existing circuit board cleaning device needs to be manually removed after the circuit board is cleaned. When the circuit board is manually removed, the surface of the circuit board is in a relatively wet state and is very easy to adhere to dirt. For this reason, we propose a circuit board cleaning device. Utility Model Content
