The bottom ends of the first fixed end plate 4 and the second fixed end plate 5 are respectively vertically fixed to the top two sides of the base 2. A servo motor 6 is horizontally fixed to the side end of the first fixed end plate 4. The output shaft of the servo motor 6 passes horizontally through the first fixed end plate 4, and an active dust-adhesive roller 7 is fixed to the output shaft of the servo motor 6. The end of the active dust-adhesive roller 7 is rotatably mounted on the second fixed end plate 5. Specifically, when the servo motor 6 is running, it can drive the active dust-adhesive roller 7 to rotate actively.

[0023] The cleaning assembly also includes an upper cover plate 8, which is U-shaped. The upper cover plate 8 is detachably mounted on the top of the first fixed end plate 4 and the second fixed end plate 5. A driven sticky roller 9 is rotatably mounted on the inner side of the upper cover plate 8. It should be noted that the driven sticky roller 9 is rotatably mounted on the inner side of the upper cover plate 8 primarily by means of a bearing (not shown in the figure). Figure 2 As shown), the driven dust roller 9 is located directly above the active dust roller 7. Both the active and driven dust rollers are made by coating the rollers with polyurethane, which provides better dust removal. When the lower surface of the PCB board 1 comes into contact with the surface of the active dust roller 7, the upper surface of the PCB board 1 comes into contact with the surface of the driven dust roller 9. Specifically, when the PCB board 1 passes between the active and driven dust rollers 7, the active dust roller 7, driven by the servo motor 6, can remove dust from the lower surface of the PCB board 1 and move the PCB board 1 at the same time, causing the driven dust roller 9 to rotate. When the driven dust roller 9 rotates, it can remove dust from the upper surface of the PCB board 1, and the removed dust can be adhered and fixed on the surfaces of the active and driven dust rollers 7 and 9. That is, the device can clean both sides of the PCB board 1 at the same time, effectively improving the cleaning efficiency of the PCB board and fixing the removed dust to avoid secondary pollution.

That is, the upper cover plate 8 can be easily disassembled and installed by operators, so that the driven dust roller 9 can be easily disassembled and installed, and thus it is convenient for operators to separate the driven dust roller 9 from the active dust roller 7 for easy cleaning.

[0025] The protective assembly includes two lower protective side plates 10. The two ends of the lower protective side plates 10 are fixed between the first fixed end plate 4 and the second fixed end plate 5.

[0026] The protective assembly also includes two upper protective side plates 11, with both ends of the upper protective side plates 11 fixed to the two sides of the upper cover plate 8. The driven dust roller 9 is located between the two upper protective side plates 11. Specifically, under the protection of the two upper protective side plates 11, the driven dust roller 9 located between the two upper protective side plates 11 can be effectively protected against impact and collision.

[0027] It should be noted that the device is electrically connected to an external main controller and 220V AC mains power, and the main controller can be an existing technology device that controls switches, etc.

[0028] The usage process of this utility model is as follows: The operator can hold the PCB board 1 to be cleaned between the active adhesive roller 7 and the driven adhesive roller 9 and manually feed it. When the PCB board 1 passes between the active adhesive roller 7 and the driven adhesive roller 9, the active adhesive roller 7, driven by the servo motor 6, can stick and remove the dust on the lower surface of the PCB board 1, and at the same time drive the PCB board 1 to move, so that the driven adhesive roller 9 can rotate. When the driven adhesive roller 9 rotates, it can stick and remove the dust on the upper surface of the PCB board 1, and the removed dust can be stuck and fixed on the surface of the active adhesive roller 7 and the driven adhesive roller 9. That is, the device can clean both sides of the PCB board 1 at the same time, effectively improving the cleaning efficiency of the PCB board, and can fix the removed dust to avoid secondary pollution.
