Background
The circuit board can be called as a printed circuit board or a printed circuit board, can miniaturize and visualize the circuit, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances.
The manufacture of the circuit board usually comprises cutting the copper foil substrate into a size suitable for processing, and before laminating the film on the substrate, roughening the copper foil on the surface of the substrate by brushing, microetching, etc. and then adhering the dry film photoresist thereon at a suitable temperature and pressure. The substrate with the dry film photoresist adhered thereon is sent into an ultraviolet exposure machine for exposure, the photoresist generates polymerization reaction after being irradiated by ultraviolet rays in the light transmission area of the negative film, and the circuit image on the negative film is transferred to the dry film photoresist on the surface of the plate. After the protective adhesive film on the film surface is torn off, the area which is not illuminated on the film surface is developed and removed by sodium carbonate aqueous solution, and then the exposed copper foil is corroded and removed by hydrochloric acid and hydrogen peroxide mixed solution to form a circuit. Finally, the dry film photoresist which is finished is washed and removed by sodium hydroxide aqueous solution.
In order to ensure the quality of the circuit board, the copper foil substrate (also called copper plate) needs to be dedusted in the processing process, and wind power dedusting and brush dedusting are mostly adopted in the prior art, so that secondary dust raising is easily generated. Electrostatic dust removal is also adopted, but the surface physical and chemical properties of the copper plate are easily influenced by static electricity.

The space between the bottom of the ash removing roller 3 and the processing platform 1 is a space for placing the copper plate 2, and after the copper plate 2 is placed, the ash removing roller 3 can be contacted with the copper plate 2. The spiral dust dipping roller 5 which can be meshed with the dust cleaning roller 3 is arranged above the dust cleaning roller 3, the dust dipping roller 5 is rotatably connected to the mounting frame 4, the surface of the dust dipping roller 5 is provided with an adhesive layer, and the rotating shaft of the dust dipping roller 5 is eccentrically arranged. The ash cleaning roller 3 and the ash dipping roller 5 are both connected with motors, and the motors are arranged on the rack. In this embodiment, the adhesive layer is made of a conventional washable traceless adhesive, for example, an adhesive used on a conventional washable hair sticking device (drying speed after washing is fast).
The cleaning mechanism for cleaning the dust dipping roller 5 is installed on the right side of the dust dipping roller 5 and comprises a cleaning box 9, and the cleaning box 9 is installed on the rack. The cleaning box 9 is rotatably provided with a rolling brush 7 which can be contacted with the ash dipping roller 5, the bristles of the rolling brush 7 are spirally arranged in cooperation with the ash dipping roller 5, and the bristles of the rolling brush 7 adopt the bristles of a washing brush in the prior art. An opening 6 for the rolling brush 7 to contact with the dust dipping roller 5 is arranged on the left side wall of the cleaning box 9. The cleaning box 9 is filled with water, and the water level is not too high, so that the water is prevented from being thrown out of the cleaning box 9 when the rolling brush 7 rotates in the water. The top of the cleaning box 9 is provided with a water inlet which is positioned above the rolling brush 7.
The rolling brush 7 is connected with a driving mechanism for driving the rolling brush 7 to be in contact with water, and the rolling brush 7 is rotatably arranged in the cleaning box 9 through the driving mechanism. Specifically, the driving mechanism comprises a connecting rod 8 which is rotatably connected to a shaft of the rolling brush 7, the connecting rod 8 is hinged to the right side wall of the cleaning box 9, the free end of the connecting rod 8 extends out of the cleaning box 9 and is connected with a power mechanism which drives the rolling brush 7 to rotate to the water around a hinged point, and a return spring is connected between the hinged point of the connecting rod 8 and the cleaning box 9. The round brush 7 is connected with the motor, and connecting rod 8 welds has the motor frame, and the motor is installed on the motor frame.
The power mechanism comprises a cam 12, the cam 12 is connected with a motor, a push rod 10 is propped against the upper part of the cam 12, and the push rod 10 is welded with the connecting rod 8.

And starting a motor connected with the ash cleaning roller 3 and the ash dipping roller 5 to drive the two to rotate, and simultaneously starting a motor connected with the cam 12 to drive the cam 12 and the incomplete gear 13 to rotate.
The dusting roller 3 is capable of causing dust on the copper plate 2 to adhere thereto by friction when in contact with the copper plate 2, thereby effecting dusting of the copper plate 2. Because the ash dipping roller 5 is meshed with the ash cleaning roller 3, when the ash dipping roller 5 is contacted with the ash cleaning roller 3, the adhesive layer on the ash dipping roller 5 can stick away the dust on the ash cleaning roller 3, thereby realizing the cleaning of the ash cleaning roller 3 and avoiding the dust from returning to the copper plate 2 again. Dust which is not adhered to the dust cleaning roller 3 can also be lifted upwards along the spiral groove on the dust cleaning roller 3 and then adhered by the dust dipping roller 5, so that the dust removal effect is increased.
The dust removal roller 3 made of silica gel removes dust from the copper plate 2, the copper plate 2 is not worn by soft silica gel, and the silica gel is neutral, so that the physical and chemical properties of the copper plate 2 are not affected.

When the dusting roller 5 rotates to contact with the rolling brush 7, the rolling brush 7 wetted with water can brush off dust on the dusting roller 5, thereby realizing cleaning of the dusting roller 5. Because the surface of the dust dipping roller 5 in the embodiment adopts the washable adhesive layer, the brush only wets water, and the redundant moisture of the brush in the rotating process can be thrown away, more moisture can not be retained on the dust dipping roller 5 after the dust dipping roller is cleaned, and dust can not be adhered to the adhesive layer again.
When the dust dipping roller 5 is separated from the rolling brush 7, the cam 12 can intermittently push the push rod 10 upwards, so that the right end of the connecting rod 8 is pushed upwards, the left end of the rolling brush 7 rotates downwards, and the rolling brush 7 is immersed in water. The rolling brush 7 rotates in the water, so that the rolling brush 7 can be cleaned, and dust on the rolling brush 7 is prevented from being adhered to the dust dipping roller 5 again.
Example two
