Description

Technical Field

[0001] The utility model relates to the technical field of substrate cleaning, in particular to a dust removal device for substrate cleaning. Background Technique

[0002] A substrate is the basic material for manufacturing a PCB. Generally, a substrate is a copper-clad laminate. In the manufacturing of single-sided and double-sided printed boards, hole processing, electroless copper plating, electroplating copper, etching, etc. are selectively carried out on the copper-clad laminate to obtain the required circuit pattern. During the production process and storage process of the substrate, dust will inevitably accumulate on the surface. Therefore, before substrate processing, dust removal work needs to be carried out on the substrate surface.

[0003] At present, the existing substrate dust removal work is usually carried out manually. Workers need to hold the substrate and an air spray gun, and use air flow injection to remove the dust on the substrate surface. However, during the dust removal process of manually holding the substrate, it is easy to collide and cause damage to the substrate, and the dust removed by air flow injection will fly around, thus polluting the working workshop environment.

The hinge 19 is fixedly connected to the front surface of the dust removal box 3. The visible door 20 is hingedly installed on the dust removal box 3 through the hinge 19. The door lock 21 is fixedly connected to the inner wall of the visible door 20 and is used to open and close the dust removal box 3, facilitating blocking the dust from flying around and at the same time facilitating observing the dust removal state of the substrate.

[0029] The air intake shunting mechanism is composed of an air inlet pipe 17 and a shunting cover 18. The air inlet pipe 17 is fixedly connected to the inner wall of the dust removal box 3. The shunting cover 18 is fixedly connected to the inner wall of the dust removal box 3 and is used to connect compressed air, facilitating the shunting work of the compressed air, increasing the dust blowing range of the substrate and improving the dust cleaning efficiency. The suction and filtration assembly is composed of a fan 12, a limit frame 13, a sealing gasket 14, a fixing frame 15 and a dust collection cloth bag 16.

After the inside of the collection box 6 is in a negative pressure state, it sucks the air and dust inside the dust removal box 3 through the box cover 7 and the bellows 8. After the dust enters the collection box 6, it is filtered and collected by the dust collection cloth bag 16. Turn on the ion generator 9 to generate negative ions in the collection box 6 to purify and sterilize the dust. When there is too much dust in the dust collection cloth bag 16, unlock the buckle lock 11 to disengage the lapping state with the hook plate 10, and use the telescopic bellows 8 to assist the box cover 7 to disengage from the collection box 6, then the fixing frame 15 and the dust collection cloth bag 16 can be taken out for dust cleaning work.

[0032] In summary, for this dust removal equipment for substrate cleaning, open the switch door assembly and place the substrate above the placement rack 5. Compressed air is shunted by the intake air shunting mechanism and blows downward onto the substrate to remove dust. The dust is blocked and adsorbed by the dust sticking film 4. At the same time, start the suction and filtration assembly to suck and filter the dust through the box cover 7 and the bellows 8. When there is too much dust, open the locking mechanism and use the telescopic bellows 8 to assist the box cover 7 to disengage from the collection box 6, then the suction and filtration assembly can be taken out for dust cleaning work, achieving the goal of facilitating the automatic cleaning and collection of substrate dust, avoiding the problems that the substrate is easily damaged by collision during the taking process and the dust scatters everywhere and pollutes the workshop environment due to manual cleaning of the substrate dust, and is used to solve the problems raised in the above-mentioned background technology.
