[0031] As Figures 1-5 shown, an embodiment of the present utility model provides a flexible circuit board cleaning device, including an installation housing 1 and a connection board 2 fixedly installed inside the installation housing 1. A plurality of adhesive rollers 3 are rotatably connected to one side of the connection board 2. Two sets of cleaning mechanisms 4 are provided inside the installation housing 1. The cleaning mechanism 4 includes a reduction motor 41. A fixing plate 42 is fixedly installed on the top of the connection board 2. One side of the reduction motor 41 is fixedly connected to one side of the fixing plate 42. Two mutually meshing gears 45 are provided inside the connection board 2. An installation plate 46 is fixedly installed on one side of the connection board 2. A rotating shaft 44 is fixedly penetrated inside the gear 45. The output end of the reduction motor 41 is fixedly connected to one end of a rotating shaft 44. A cleaning brush 47 is movably installed on the outer wall of the rotating shaft 44. A first protective cover 410 is provided on the outer wall of one cleaning brush 47. A horizontal part 411 is provided on one side of the first protective cover 410. A first cleaning plate 412 is fixedly installed on one side of the horizontal part 411. A first collection box 413 is slidably connected to the horizontal part 411. A second protective cover 414 is provided on the outer wall of the other cleaning brush 47. A second cleaning plate 415 is fixedly installed at one end of the second protective cover 414. A second collection box 416 is slidably connected to the bottom of the second protective cover 414. The second protective cover 414 is slidably connected to the connection board 2.

[0032] When using this device to clean a flexible circuit board, start the reduction motor 41 to drive the rotating shaft 44 and the cleaning brush 47 to rotate. The rotating shaft 44 rotates inside the mounting plate 46. The rotating shaft 44 drives the gear 45 to rotate, and the gear 45 drives another meshing gear 45 to rotate, realizing the rotation of the two cleaning brushes 47. Push the circuit board in from one side of the cleaning brush 47. While the cleaning brush 47 cleans the surface of the circuit board, it also drives the circuit board to move. The long hair part of the cleaning brush 47 gets contaminated with dust. When the cleaning brush 47 passes by the first cleaning plate 412, the long hair part of the cleaning brush 47 is scraped by the first cleaning plate 412. The first cleaning plate 412 scrapes off the dust, and the dust slides down along the inclined surface of the first cleaning plate 412 to the horizontal part 411 and finally falls into the interior of the first collection box 413. At the same time, the second cleaning plate 415 scrapes the long hair part of the other cleaning brush 47, and the dust falls into the interior of the second protective cover 414 and finally gathers in the interior of the second collection box 416. And when the upper cleaning brush 47 cleans the circuit board, some dust directly falls into the interior of the second protective cover 414. By setting the first cleaning plate 412 and the second cleaning plate 415 to scrape and clean the long hair part of the cleaning brush 47, the accumulated dirt, dust and fibers are removed, ensuring that the cleaning brush 47 can maintain the best cleaning and brushing effect during use. Through effective cleaning and maintenance, the need for frequent replacement of the brush roller can be reduced, thereby reducing the long-term maintenance and use costs.

[0033] As Figure 6 shown, the cleaning brush 47 is composed of two halves spliced together. One end of the cleaning brush 47 is provided with a mounting part 48. An installation groove is opened on the mounting part 48, and a fixing bolt 49 is installed through the installation groove. The cleaning brush 47 is installed on the outer wall of the rotating shaft 44 through the fixing bolt 49. When the cleaning brush 47 needs to be replaced after long-term use, after removing the first protective cover 410 and the fixing plate 42, the cleaning brush 47 is exposed. After removing the fixing bolt 49, the two halves of the cleaning brush 47 are removed and replaced. Then, the two halves of the new cleaning brush 47 are clamped on the outer wall of the rotating shaft 44, and then the mounting part 48 is installed on the outer wall of the rotating shaft 44 using the fixing bolt 49 to fix the cleaning brush 47. By setting the cleaning brush 47 with a two-half structure and being detachable, the installation and disassembly of the cleaning brush 47 are simple and fast, thus ensuring the cleaning effect of the cleaning brush 47.

[0034] As Figure 1 and Figure 2 shown, pull rings 43 are fixedly installed on one side of both the first collection box 413 and the second collection box 416. By setting the pull rings 43, it is convenient to detach the first collection box 413 from one side of the first protective cover 410 and to detach the second collection box 416 from one side of the second protective cover 414.

[0035] AsFigure 2 As shown, the fixing plate 42 and the first protective cover 410 are movably installed by buckles, and the fixing plate 42 and the second protective cover 414 are movably installed by buckles. The fixing plate 42 facilitates the installation and disassembly of the first protective cover 410 and the second protective cover 414. When the cleaning roller brush 47 is working, the first protective cover 410 and the second protective cover 414 play a role in dust prevention.

[0036] As Figure 2 shown, a sliding groove for the movement of the first collection box 413 is provided on the connecting plate 2. By setting the sliding groove, the first collection box 413 is supported and limited.

[0037] As Figure 2 shown, the end of the first collection box 413 far from the pull ring 43 is flush with the side end of the cleaning roller brush 47 in the vertical direction, and the end of the second collection box 416 far from the pull ring 43 is flush with the side end of the cleaning roller brush 47 in the vertical direction. The dust contaminated by the cleaning of the cleaning roller brush 47 is scraped by the first cleaning plate 412 into the first collection box 413 and by the second cleaning plate 415 into the second collection box 416.

[0038] In the technical solution provided by the present utility model, when using this device to clean a flexible circuit board, the reduction motor 41 is started to drive the rotating shaft 44 and the cleaning roller brush 47 to rotate. The rotating shaft 44 rotates inside the mounting plate 46. The rotating shaft 44 drives the gear 45 to rotate, and the gear 45 drives another meshing gear 45 to rotate, realizing the rotation of the two cleaning roller brushes 47. The circuit board is pushed in from one side of the cleaning roller brush 47. While the cleaning roller brush 47 cleans the surface of the circuit board, it also drives the circuit board to move. The long hair part of the cleaning roller brush 47 is contaminated with dust. When the cleaning roller brush 47 passes by the first cleaning plate 412, the long hair part of the cleaning roller brush 47 is scraped by the first cleaning plate 412. The first cleaning plate 412 scrapes off the dust, which slides along the inclined surface of the first cleaning plate 412 to the horizontal part 411 and finally falls into the first collection box 413. At the same time, the second cleaning plate 415 scrapes the long hair part of the other cleaning roller brush 47, and the dust falls into the second protective cover 414 and finally gathers in the second collection box 416. And when the cleaning roller brush 47 above is cleaning the circuit board, some dust directly falls into the second protective cover 414. When the cleaning roller brush 47 needs to be replaced after long-term use, after removing the first protective cover 410 and the fixing plate 42, the cleaning roller brush 47 is exposed. After removing the fixing bolt 49, the two halves of the cleaning roller brush 47 are removed and replaced. Then, the two halves of the new cleaning roller brush 47 are clamped on the outer wall of the rotating shaft 44, and then the mounting part 48 is installed on the outer wall of the rotating shaft 44 using the fixing bolt 49 to fix the cleaning roller brush 47.

In order to enable the public to have a thorough understanding of the present utility model, specific details have been described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can also fully understand the present utility model without the description of these details.

[0040] The above description is only the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
