[0040] A first aspect of the present application is to provide a brush pre-cleaning device for pre-cleaning a target brush 30 when the target brush 30 is not in working time.

[0041] The brush pre-cleaning device comprises a first cleaning member 10 and a second cleaning member 20 .

[0042] See also Figures 1 to 4 Preferably, the first cleaning member 10 can be a tubular structure, the interior of the first cleaning member 10 is hollow, and a cleaning cavity 11 and a water injection channel 12 are provided at the top of the first cleaning member 10, wherein the cleaning cavity 11 extends along the axial direction of the first cleaning member 10, the water injection channel 12 extends along the radial direction of the first cleaning member 10 and penetrates the wall thickness of the first cleaning member 10, and the water injection channel 12 is connected with the cleaning cavity 11 for injecting clean water into the cleaning cavity 11. The first cleaning member 10 is also provided with a drain port 13, which is located below the cleaning cavity 11 in the vertical direction, and is connected with the cleaning cavity 11, and is used to discharge the clean water in the first cleaning member 10.

[0043] The second cleaning member 20 is detachably connected to the cleaning chamber 11 , and is used to abut against the upper first cleaning surface 31 of the target brush 30 , wherein the first cleaning surface 31 is used to clean the substrate.

[0044] It should be noted that the material of the second cleaning member 20 is the same as the material of the substrate to be cleaned. For example, when the material of the substrate to be cleaned is glass, the material of the second cleaning member 20 is also glass.

[0045] The second cleaning member 20 is detachably connected to the cleaning chamber 11 , so that the operator can easily replace the second cleaning member 20 made of different materials, so that the material of the second cleaning member 20 is consistent with the material of the substrate to be cleaned.

[0046] The target brush 30 is connected to a driving mechanism including a rotary motor. The target brush 30 is connected to the rotary motor and driven to rotate by the rotary motor. When the target brush 30 rotates relative to the second cleaning member 20 , the water injection channel 12 injects cleaning water into the target brush 30 to clean the target brush 30 .

[0047] Compared with the prior art, the pre-cleaning device for the brush provided in the present application includes a first cleaning member 10 and a second cleaning member 20. The second cleaning member 20 is detachably connected to the first cleaning member 10. The second cleaning member 20 made of the same material as the target substrate can be selected as needed to be installed in the first cleaning member 10. When the target brush 30 is not in working time, the driving mechanism for driving the target brush 30 to rotate drives the target brush 30 to move into the first cleaning member 10 and abut against the second cleaning member 20, and the driving mechanism drives the target brush 30 to rotate relative to the second cleaning member 20. At the same time, the water injection channel 12 arranged on the first cleaning member 10 injects cleaning water into the target brush 30 to rinse the dust cleaned from the target brush 30 by the second cleaning member, thereby improving the cleaning speed of the target brush 30, realizing rapid cleaning of the target brush 30, and reducing the pre-cleaning time of the target brush 30.

Figure 7 As shown, when the diameter of the preset motion path 211 is greater than the dimension of the second cleaning surface 21 in the width direction, the preset motion path 211 is an arc symmetrically arranged along the width direction of the second cleaning surface 21 .

[0053] When the target brush 30 rotates relative to the second cleaning surface, the axis of the target brush 30 moves along the preset motion path 211 to ensure that the first cleaning surface 31 and the target brush 30 rotation axis coincide with each other and the area with zero linear velocity can also be cleaned by the second cleaning surface 21 .

[0054] It should be noted that the driving mechanism for driving the target brush 30 to rotate also includes a driving arm, such as a robotic arm, for driving the target brush 30 to move along a preset path. The driving arm can also be used to drive the target brush 30 into and out of the cleaning chamber 11.

By arranging the first opening of the slot 14 on the top wall of the first cleaning member 10, the connecting member 15 can be installed in the slot 14 along the vertical direction, or removed from the slot 14 along the vertical direction, thereby facilitating replacement of the second cleaning member 20 made of different materials.

[0057] See also Figure 1 and Figure 3 In one embodiment of the present application, the brush pre-cleaning device also includes a water injection pipe 40.

[0058] One end of the water injection pipe 40 is connected to the water injection channel 12, or one end of the water injection pipe 40 is inserted into the inlet end of the water injection channel 12, and the other end of the water injection pipe 40 is connected to a water outlet mechanism, such as a water tank, a water storage tank or a booster pump, to inject clean water into the water injection channel 12.

[0059] There are multiple water injection channels 12 , which are evenly spaced apart along the circumference of the first cleaning member 10 , and each water injection channel 12 is connected to a water injection pipe 40 .
