Description

Technical Field

[0001] The present application relates to the technical field of circuit boards, and in particular to a circuit board brushing machine. Background Art

[0002] A circuit board scrubber is a device used to process and clean circuit boards. It usually consists of multiple brushes or scrapers that can be operated automatically or manually to remove dirt, oxides, residues and other impurities from circuit boards. This equipment can improve the cleanliness and quality of circuit boards and extend their service life. A circuit board scrubber can also be used to apply chemicals or lubricants to circuit boards to improve the performance and reliability of the circuit boards. In the field of electronic manufacturing and repair, a circuit board scrubber is a very useful tool that helps professionals process circuit boards quickly and efficiently.

[0003] In the prior art, board brushing machines are usually divided into semi-automatic and fully automatic. Semi-automatic machines require manual use of hands or clamps to brush the circuit board to be cleaned through a brush wheel, while fully automatic machines only require placing the circuit board on the brush trigger and then moving the circuit board along the path to the brush wheel for brushing. However, the dirt, oxides, and residues cleaned by the brush wheel will be scattered along the brush wheel during cleaning, and will be splashed back onto the circuit board to a certain extent.
