Description

A circuit board dust removal and cleaning machine

Technical Field

The present application relates to the technical field of circuit board dust removal, and in particular to a circuit board dust removal and cleaning machine.

Background technique

At present, with the development of society, the application of electronic equipment is becoming more and more extensive, and as the core component of electronic equipment, the demand for circuit boards is also increasing day by day. However, during the production and processing of circuit boards, static electricity often causes a large amount of dust to be adsorbed on the surface of the circuit board, thereby reducing the working efficiency and service life of the circuit board. Therefore, it is particularly important to remove dust from the circuit board. In the related art, an air gun is usually used to directly blow air on the surface of the circuit board to remove dust.

Regarding the above-mentioned related technologies: the air gun directly blows away the dust on the surface of the circuit board. On the one hand, the dust is easy to fall back onto the circuit board after leaving the circuit board. On the other hand, due to the influence of static electricity, it is difficult for the air gun to effectively blow away the dust from the surface of the circuit board, resulting in a problem of low dust removal efficiency.

Summary of the invention

At this time, the dust suction mechanism can drive the gas to flow from the storage chamber to the dust collection chamber, and the gas drives the dust to flow into the dust collection chamber, so that the dust leaves the storage chamber, and makes it difficult for the dust to fall back onto the circuit board again after being blown up, thereby facilitating the removal of dust on the circuit board and improving the dust removal efficiency to a certain extent.

The fan 41 is installed in the second chamber 122, and the filter cartridge 42 is installed in the first chamber 121, and the filter cartridge 42 is located at the connection between the first chamber 121 and the second chamber 122, so that the gas flowing between the first chamber 121 and the second chamber 122 needs to pass through the filter cartridge 42, so that the filter cartridge 42 can filter the gas.

1 , in this embodiment, two filter cartridges 42 are provided, and the two filter cartridges 42 are parallel to each other, so that more gas can be filtered in a unit time through the cooperation of the two filter cartridges 42 .

2 , when the fan 41 is working, the fan 41 can form a negative pressure in the second chamber 122 and the first chamber 121 to suck the gas in the storage chamber 11 into the first chamber 121. The gas drives the dust in the storage chamber 11 into the first chamber 121 and enters the second chamber 122 through the filter cartridge 42, thereby facilitating the filtering of the gas. On the one hand, the gas flowing into the second chamber 122 is relatively clean, so as to improve the cleanliness of the gas discharged into the atmosphere. On the other hand, it is beneficial to reduce the possibility of dust floating back from the first chamber 121 into the storage chamber 11 and falling onto the circuit board 5.

2 , a dust drawer 18 is slidably connected to the box body 1, one end of the dust drawer 18 is inserted in the first chamber 121, and the dust drawer 18 is located below the filter cartridge 42, so that the dust falling from the filter cartridge 42 can be collected in the dust drawer 18, so that the staff can centrally process the dust.

Next, the static electricity removal mechanism 2 is started, and the static electricity removal mechanism 2 blows air with plasma to the circuit board 5 to neutralize the static electricity on the circuit board 5. Then, the air bag 31 is started, and the on-off valve is started, so that the air bag 31 intermittently supplies air to the nozzle 33, so that the nozzle 33 intermittently sprays the circuit board 5, thereby blowing away the dust on the circuit board 5.

Embodiment 2:

5 , the difference between Embodiment 2 and Embodiment 1 is that the support member 32 is arranged in a long strip shape.

2 and 5 , the length of the support member 32 is equal to the length of the dust removal station 13, and the support member 32 is arranged along the length direction of the dust removal station 13, so that when the dust separated from the circuit board 5 moves into the first chamber 121, it is not easily blocked by the support member 32, so as to reduce the possibility of dust being deposited on the support member 32, and further help to reduce the possibility of dust deposited on the support member 32 falling onto the circuit board 5, thereby ensuring the dust removal effect on the circuit board 5 to a certain extent.

The end of the filter cartridge 42 close to the second chamber 122 is fixedly connected with a rotating blade 421. When the fan 41 is working, the gas will flow through the rotating blade 421, causing the rotating blade 421 to rotate, and the rotating blade 421 drives the filter cartridge 42 to rotate, which is helpful to reduce the possibility of the filter cartridge 42 being blocked due to excessive local deposition of dust on the filter cartridge 42 when the filter cartridge 42 filters the dust in the gas, and is also helpful to make the dust deposited relatively evenly on the surface of the filter cartridge 42, which improves the filtering efficiency of the filter cartridge 42 to a certain extent and prolongs the service life of the filter cartridge 42.

When the nozzle 33 blows the dust on the circuit board 5 into the first chamber 121 and the fan 41 is working, the gas will drive the dust through the filter cartridge 42 so that the filter cartridge 42 can intercept the dust in the gas, and the filtered gas will pass through the rotating blades 421 to make the rotating blades 421 rotate, thereby facilitating the driving of the filter cartridge 42 to rotate, which is beneficial to reduce the possibility of dust adhering to the rotating blades 421.

The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
