[0049] It is worth noting that the mobile module in this embodiment is a mobile rotation module structure commonly used in the prior art. The specific structure of the mobile module will not be described in detail here. It is sufficient to ensure that the middle frame can move on the X-axis and Y-axis and rotate within the rotation plane through the mobile module.

[0050] Furthermore, if Figure 1 and Figure 2 As shown, the wiping module 10 also includes a discharge roller 4, a take-up roller 6, and several guide rollers 5, which are spaced apart on the support frame 1. A dust-free cloth 14 is wound on the discharge roller 4. The discharge roller 4 is used to roll out the dust-free cloth 14 and can be guided along the tensioning direction to the take-up roller 6 via several guide rollers 5, so that the take-up roller 6 can reel in the dust-free cloth 14 after wiping the middle frame, thereby realizing the recovery of the dust-free cloth 14. Furthermore, a placement tray 13 is fixedly mounted on both the discharge roller 4 and the take-up roller 6. The placement tray 13 is used to place and support the rolled dust-free cloth 14. The tensioning direction specifically refers to the direction in which the dust-free cloth 14 is set from the discharge roller 4 to the take-up roller 6, that is, the arrangement route of the dust-free cloth 14 from the discharge roller 4 to the take-up roller 6 is the tensioning direction. The X-axis is parallel to the length direction of the support frame 1, and the Y-axis is parallel to the width direction of the support frame 1. In this embodiment, there are three guide rollers 5, and the specific number of guide rollers 5 is not limited.

[0051] Specifically, if Figure 1 and Figure 2 As shown, a detector 11 is also provided on the support frame 1. The detector 11 is used to detect the thickness of the dust-free cloth 14 rolled on the discharge roller 4 so that the dust-free cloth 14 can be replenished on the discharge roller 4 in a timely manner when the dust-free cloth 14 on the discharge roller 4 is almost exhausted. In this embodiment, the detector 11 is specifically a distance sensor.

[0052] Specifically, if Figure 1 and Figure 2As shown, the wiping module 10 also includes a first torque motor 7 and a second torque motor 8; wherein the fixed end of the first torque motor 7 is set on the support frame 1, and the output end of the first torque motor 7 is drive-connected to the discharge roller 4, and the fixed end of the second torque motor 8 is set on the support frame 1, and the output end of the second torque motor 8 is drive-connected to the take-up roller 6; wherein the first torque motor 7 is used to provide a pulling force to the discharge roller 4 in the opposite direction of the unwinding direction of the dust-free cloth 14, and the second torque motor 8 is used to provide a pulling force to the take-up roller 6 in the same direction as the reeling direction of the dust-free cloth 14, thereby tightening the dust-free cloth 14 from both ends of the discharge roller 4 and the take-up roller 6, so that the dust-free cloth 14 can always remain in a tensioned state, thereby ensuring the wiping effect of the dust-free cloth 14 on the center frame. wherein the first torque motor 7 and the second torque motor 8 are both drive-connected to the discharge roller 4 and the take-up roller 6 respectively through a transmission structure commonly used in the prior art of a transmission belt and a transmission wheel. The specific transmission principle of the transmission structure will not be described in detail here.

[0053] Furthermore, if Figure 1 and Figure 2 As shown, the wiping module 10 also includes a traction assembly 9 for pulling the dust-free cloth 14 to feed along the tensioning direction; specifically, the traction assembly 9 includes a traction roller 91, a clamping cylinder 92, and a clamping roller 93. The traction roller 91 is arranged on the support frame 1, and the traction roller 91 is located between the receiving roller 6 and the guide roller 5. The traction roller 91 can rotate relative to the support frame 1 along the tensioning direction; the fixed end of the clamping cylinder 92 is arranged on the support frame 1, and the driving end of the clamping cylinder 92 is driven and connected to the clamping roller 93, so that the clamping cylinder 92 can drive the clamping roller 93 to abut against the traction roller 91, so as to clamp the dust-free cloth 14 between the clamping roller 93 and the traction roller 91, so that the dust-free cloth 14 can be fed along the tensioning direction under the rotation of the traction roller 91. The feeding direction of the dust-free cloth 14 is the same as the tensioning direction.

[0054] Specifically, if Figure 1 As shown, the traction assembly 9 also includes a driving motor 94, a driving wheel 95, a driven wheel 96 and a synchronous belt 97; wherein, the fixed end of the driving motor 94 is arranged on the support frame 1, the output shaft of the driving motor 94 is fixedly sleeved with the driving wheel 95, the driven wheel 96 is fixedly sleeved on the traction roller 91, and the two ends of the synchronous belt 97 are respectively sleeved on the driving wheel 95 and the driven wheel 96; when the driving motor 94 is running, the output shaft of the driving motor 94 can drive the driving wheel 95 to rotate, thereby driving the synchronous belt 97 and the driven wheel 96 to rotate, thereby driving the traction roller 91 to rotate.

[0055] Furthermore, if Figure 1-Figure 3As shown, the first wiping assembly includes a first driving member 21 and a first wiping head 22; wherein, the fixed end of the first driving member 21 is arranged on the support frame 1, and the driving end of the first driving member 21 is driven and connected to the first wiping head 22, and the first wiping head 22 has a first wiping surface 221, and the first wiping surface 221 is a vertical plane. The first driving member 21 is used to drive the first wiping head 22 to move along the Y axis to abut against one side of the dust-free cloth 14, and at the same time, the moving module can drive the side of the middle frame to abut against the dust-free cloth 14. The other side and the first wiping surface 221; that is, at this time, the side of the middle frame can be pressed against the first wiping surface 221 by pressing the dust-free cloth 14, that is, the side of the middle frame and the first wiping surface 221 form a mutual abutment relationship, and the dust-free cloth 14 is located between the side of the middle frame and the first wiping surface 221; then, the moving module drives the middle frame to move along the X-axis on the part of the dust-free cloth 14 that abuts against the first wiping surface 221, thereby achieving the purpose of wiping the side of the middle frame. In this embodiment, the first driving member 21 can be specifically a cylinder.

[0056] Specifically, if Figure 1 and Figure 3 As shown, the first wiping assembly also includes a second wiping head 23, which is driven and connected to the driving end of the first driving member 21. The second wiping head 23 is located on one side of the first wiping head 22, that is, the second wiping head 23 is arranged closely to the first wiping head 22, and the first driving member 21 can drive the first wiping head 22 and the second wiping head 23 to move synchronously along the Y-axis; and the second wiping head 23 has a second wiping surface 231 and a third wiping surface 232, and the third wiping surface 232 is located between the first wiping surface 221 and the second wiping surface 231, and the second wiping surface 231 is an inclined surface, and the second wiping surface 231 is used to wipe the fillet between two adjacent side surfaces of the middle frame.

[0057] Specifically, if Figure 3 As shown, the third wiping surface 232 is a vertical plane, and the third wiping surface 232 is flush with the first wiping surface 221 on the Y-axis, that is, the third wiping surface 232 and the first wiping surface 221 are located on the same vertical plane, so that after the second wiping surface 231 wipes the rounded corners of the middle frame, the side of the middle frame can be smoothly transitioned to the first wiping surface 221 through the third wiping surface 232, so that the first wiping surface 221 can wipe the side of the middle frame, thereby ensuring that the wiping actions on the rounded corners and the side of the middle frame can be connected with each other, that is, the third wiping surface 232 can also wipe the side of the middle frame.

[0058] When it is necessary to wipe the rounded corner between two adjacent side surfaces on the middle frame, the moving module drives the rounded corner of the middle frame to squeeze the dust-free cloth 14 and abut against the second wiping surface 231, and then the moving module drives the middle frame to move along the inclined direction of the second wiping surface 231, so that the rounded corner on the middle frame can be tilted and moved on the part of the dust-free cloth 14 that abuts against the second wiping surface 231, so that the second wiping surface 231 can wipe the rounded corner of the middle frame through the dust-free cloth 14; thereafter, the moving module drives one of the two adjacent side surfaces on the middle frame to move along the X-axis on the part of the dust-free cloth 14 that abuts against the third wiping surface 232 and the first wiping surface 221, so as to achieve wiping of the side surface of the middle frame, thereby achieving the purpose of wiping the rounded corner and side of the middle frame in turn.

[0059] The number of the first wiping head 22 and the second wiping head 23 can be set to multiple, so that the middle frame can be wiped multiple times by multiple first wiping heads 22 and multiple second wiping heads 23 to achieve better wiping effect. Figure 1-Figure 3 As shown, only one first wiping head 22 and one second wiping head 23 are provided.

[0060] Furthermore, if Figure 1 and Figure 2 As shown, the first wiping assembly further includes a spray head 24 and a spray valve 25. The spray head 24 is disposed on the support frame 1 and located to one side of the second wiping head 23. The spray head 24 is used to spray a wiping agent onto the dust-free cloth 14, so that the portion of the dust-free cloth 14 that abuts the first wiping head 22 and the second wiping head 23 is always wet. The spray valve 25 is disposed on the support frame 1 and is controllably connected to the spray head 24. The spray valve 25 is used to control the amount of wiping agent sprayed by the spray head 24. In this embodiment, the wiping agent can specifically be alcohol.

[0061] By setting the spray head 24, the part of the dust-free cloth 14 that abuts against the first wiping head 22 and the second wiping head 23 can always be in a wet state, so that wet wiping of the side and rounded corners of the middle frame can be achieved, so that the middle frame can be wiped clean by the dust-free cloth 14 in a wet state, further ensuring the wiping effect of the middle frame.

[0062] The spray valve 25 in this embodiment is a low-cost manual regulating valve; after the spray valve 25 is adjusted, the wiping amount sprayed by the spray valve 25 is a certain value. At this time, the spraying time of the spray head 24 on the dust-free cloth 14 can be controlled to ensure that the part of the dust-free cloth 14 that is in contact with the first wiping head 22 and the second wiping head 23 can always be in a wet state, while the dust-free cloth 14 located outside the first wiping head 22 and the second wiping head 23 is in a dry state.

[0063] Furthermore, if Figure 2As shown, the spray head 24 includes a swab tube 241, a spray hole 242, a swab interface, and a gas interface 243. The swab tube 241 is vertically mounted on the support frame 1, and a plurality of spray holes 242 are provided on the swab tube 241. The swab interface and the gas interface 243 are both provided on the swab tube 241. The swab interface is used to supply wiping agent into the swab tube 241 and can drive the wiping agent to be sprayed through the spray holes 242 onto the dust-free cloth 14 in a spraying state, so that the dust-free cloth 14 is kept wet. The gas interface 243 is used to supply pressurized gas into the swab tube 241 when the swab interface stops working. In this embodiment, there are three spray holes 242, which are evenly arranged around the swab tube 241 so that each spray hole 242 can evenly spray the wiping agent onto the dust-free cloth 14. There is no limit on the number of spray holes 242.

[0064] By setting up a gas interface 243, it is possible to provide gas with a certain pressure into the wiper tube 241 when the wiper interface stops working, so that the gas can spray the water droplet-shaped wiper formed in the spray hole 242 due to the cessation of the wiper interface onto the dust-free cloth 14 in a spray shape, thereby avoiding the problem of the water droplet-shaped wiper formed in the spray hole 242 directly dripping onto the dust-free cloth 14 or directly falling off.

[0065] Furthermore, if Figure 2 As shown, a receiving frame 12 is also provided on the support frame 1. The receiving frame 12 is located below the swab tube 241 and the dust-free cloth 14 to receive the wiping agent dripping from the swab tube 241 or the dust-free cloth 14, preventing the wiping agent from directly dripping and damaging the device disposed below the swab tube 241 or the dust-free cloth 14. At the same time, the receiving frame 12 can also receive impurities wiped from the middle frame by the first wiping assembly and the second wiping assembly. The size and shape of the receiving frame 12 are not limited, as long as it can receive the wiping agent dripping from the swab tube 241 or the dust-free cloth 14, and can also receive impurities on the middle frame wiped by the first wiping assembly and the second wiping assembly.

[0066] Specifically, along the tensioning direction, the second wiping assembly is located upstream of the first wiping assembly, so that the moving module can first drive the middle frame to move to the first wiping assembly for wiping, and then drive the middle frame to move to the second wiping assembly for wiping; that is, after the first wiping assembly wet-wipes the middle frame, the second wiping assembly dry-wipes the middle frame, so that the residual wiping agent on the middle frame can be wiped clean, to ensure that the middle frame can remain dry after being wiped by the second wiping assembly, thereby better ensuring the wiping effect on the middle frame.

[0067] Furthermore, if Figure 1-Figure 3As shown, the second wiping assembly includes a second driving member 31 and a third wiping head 32; wherein, the fixed end of the second driving member 31 is arranged on the support frame 1, and the driving end of the second driving member 31 is driven and connected to the third wiping head 32; the third wiping head 32 includes two finger wiping blocks 321 arranged opposite to each other in the vertical direction, and the two finger wiping blocks 321 can move closer to or away from each other, and the second driving member 31 is used to simultaneously drive the two finger wiping blocks 321 to move along the Y axis to abut against one side of the dust-free cloth 14, and the moving module can drive the middle frame to move to abut against the dust-free cloth On the other side of the dust cloth 14, opposite the two finger wipers 321, the moving module can also drive the middle frame and the dust cloth 14 along the Y-axis to squeeze between the two finger wipers 321 and move along the X-axis, so that the two finger wipers 321 can form a finger-clamping structure to clamp the upper and lower surfaces of the middle frame. At this time, the dust cloth 14 is wrapped around the portion of the middle frame that squeezes between the two finger wipers 321. The moving module then drives the middle frame to move between the two finger wipers 321 along the X-axis, thereby wiping the side and upper and lower surfaces of the middle frame. In this embodiment, the second driving member 31 is specifically a cylinder.

[0068] By enabling the two finger wiping blocks 321 to form a finger clamping structure to clamp the upper and lower surfaces of the middle frame, the two finger wiping blocks 321 can further wipe the sides of the middle frame through the dust-free cloth 14 at the same time. On the one hand, the impurities on the sides of the middle frame can be wiped a second time to wipe the sides of the middle frame more cleanly; on the other hand, the wiping agent remaining on the sides of the middle frame can be wiped dry, and no water stains will be formed on the sides of the middle frame. At the same time, since the two finger wiping blocks 321 can wipe the upper and lower surfaces of the middle frame by clamping the upper and lower surfaces of the middle frame through the dust-free cloth 14, the impurities on the upper and lower surfaces of the middle frame can be wiped clean better; at the same time, the wiping agent splashed on the upper and lower surfaces of the middle frame can be wiped dry, ensuring that no water stains will be formed on the upper and lower surfaces of the middle frame, and ensuring that the middle frame can be in a dry state.

[0069] Specifically, the number of the third wiping heads 32 can be set to multiple, so that the middle frame can be wiped multiple times by multiple third wiping heads 32 to achieve better wiping effect. Figure 1-Figure 3 As shown, two third wiping heads 32 are provided, and the two third wiping heads 32 are spaced apart so as to be able to wipe the upper and lower sides of the middle frame twice, front and back, further ensuring the wiping effect of the middle frame. In order to save the number of driving parts and reasonably arrange the installation space, one of the two third wiping heads 32 is driven and connected to the first driving part 21, and the other third wiping head 32 is driven and connected to the second driving part 31. This is not limited here, as long as it can be ensured that the first wiping head 22, the second wiping head 23 and the third wiping head 32 are all moved to the side against the dust-free cloth 14 by each driving part.

[0070] It is worth noting that since the dust-free cloth 14 has a certain elasticity, it is also possible to set the specific positions of each guide roller 5 on the support frame 1, and through the drive control of the first drive member 21 and the second drive member 31, it is possible to ensure that the first wiping head 22, the second wiping head 23 and the third wiping head 32 can all be against one side of the dust-free cloth 14 to facilitate wiping of the center frame.

[0071] Specifically, if Figure 3 and Figure 4 As shown, the finger wiper 321 has a fourth wiping surface 3211 in a horizontal plane; when the middle frame is squeezed into the two finger wipers 321, the fourth wiping surface 3211 can abut against the upper and lower surfaces of the middle frame, and the dust-free cloth 14 is located between the fourth wiping surface 3211 and the upper and lower surfaces of the middle frame.

[0072] Specifically, if Figure 3 and Figure 4 As shown, the third wiping head 32 also includes a base plate 322 and a tension spring 323. The base plate 322 is drivingly connected to the driving end of the second driving member 31, and the two finger wipers 321 are relatively and rotatably arranged on the base plate 322. One end of the tension spring 323 is connected to one of the finger wipers 321, and the other end of the tension spring 323 is connected to the other finger wiper 321. The tension spring 323 is used to move the two finger wipers 321 closer to or farther away from each other. A rotating rod 325 is provided on the base plate 322. One end of the rotating rod 325 is fixedly connected to the base plate 322, and the other end of the rotating rod 325 is rotatably connected to the finger wiper 321, so that the finger wiper 321 can rotate around the rotating rod 325 relative to the base plate 322.

[0073] The two finger wipers 321 are brought close to each other by the tension spring 323, so that when the second wiping head 23 wipes the middle frame, the moving module drives the middle frame to squeeze into the two finger wipers 321, so that when the middle frame moves between the two fourth wiping surfaces 3211, the two finger wipers 321 will generate an extrusion force on the upper and lower surfaces of the middle frame to move closer to each other, so that the two finger wipers 321 have a better pressing effect on the middle frame, thereby ensuring that the middle frame can more easily wipe off impurities on the upper and lower surfaces of the middle frame when it moves between the two fourth wiping surfaces 3211.

[0074] Furthermore, if Figure 4As shown, the third wiping head 32 also includes an adjusting block 324, which is fixedly arranged on the base plate 322, and the two finger wiping blocks 321 are respectively located on opposite sides of the adjusting block 324 in the vertical direction, and the finger wiping blocks 321 can rotate relative to the adjusting block 324. The adjusting block 324 is used to adjust the gap distance between the two finger wiping blocks 321 when they are not squeezed by the middle frame, so that the gap distance is less than 0.2mm-0.4mm of the thickness of the middle frame. The gap distance is specifically the relative distance between the two fourth wiping surfaces 3211 on the upper and lower finger wiping blocks 321.

[0075] By ensuring the gap is less than 0.2 mm to 0.4 mm, which is the thickness of the middle frame, the middle frame requires some effort to fit between the two finger wipers 321. However, this ensures that the middle frame fits easily between the two finger wipers 321 and does not wear the middle frame during the insertion process, thereby effectively protecting the middle frame. In this embodiment, the gap is less than 0.2 mm, which is the thickness of the middle frame.

[0076] Specifically, if Figure 4 As shown, a first inclined surface 3212 is formed on the finger wiper block 321 on one side close to the adjustment block 324, and the first inclined surface 3212 and the fourth wiping surface 3211 are located on the same side of the finger wiper block 321, and a second inclined surface 3241 is formed on the adjustment block 324; when the middle frame is not squeezed between the two finger wipers 321, the first inclined surface 3212 and the second inclined surface 3241 are completely fitted together, and the connection between the first inclined surface 3212 and the fourth wiping surface 3211 abuts against the second inclined surface 3241, so that the connection between the first inclined surface 3212 and the fourth wiping surface 3211 can limit the further sliding of the first inclined surface 3212 on the second inclined surface 3241 under the action of the tension spring 323, so as to limit the two finger wipers 321 from further approaching each other under the action of the tension spring 323. At this time, the distance between the two fourth wiping surfaces 3211 on the two finger wipers 321 is the gap distance.

[0077] It is worth noting that the size of the gap distance can be controlled by adjusting the specific abutment position of the connection between the first inclined surface 3212 and the fourth wiping surface 3211 on the second inclined surface 3241, so that the gap distance can be adjusted according to the thickness of the middle frame, so that the second wiping head 23 can wipe the middle frames of different thicknesses, thereby making the wiping device more versatile.

[0078] When the middle frame is squeezed into the two finger wipers 321, the finger wiper 321 can rotate around the rotating rod 325 under the squeezing action of the middle frame. At this time, the first inclined surface 3212 and the second inclined surface 3241 are separated from each other, and one end of the first inclined surface 3212 can slide smoothly on the second inclined surface 3241, thereby realizing the two finger wipers 321 moving away from each other; when the middle frame is moved out from the two finger wipers 321, the two finger wipers 321 can rotate around the rotating rod 325 under the tension of the tension spring 323 until they are close to each other. When the first inclined surface 3212 and the second inclined surface 3241 are completely fitted together and the connection between the first inclined surface 3212 and the fourth wiping surface 3211 abuts against the second inclined surface 3241, the two finger wipers 321 can no longer continue to rotate close to each other under the tension of the tension spring 323, so that the distance between the two finger wipers 321 is restored to the original gap distance.

[0079] The specific wiping process of the wiping device in this embodiment is as follows:

[0080] First, manually install the dust-free cloth 14 from the discharge roller 4 to the receiving roller 6 through each guide roller 5, and clamp the dust-free cloth 14 between the traction roller 91 and the clamping roller 93, so that the dust-free cloth 14 can be driven to feed along the tensioning direction under the rotation of the traction roller 91; then vacuum adsorb the middle frame on the top surface of the moving module, so that the moving module drives the middle frame to move and rotate along the X-axis and Y-axis until the rounded corner on the middle frame abuts against one side of the dust-free cloth 14; at the same time, the first driving member 21 drives the second wiping The head 23 moves along the Y-axis to the other side against the dust-free cloth 14, and the moving module drives the rounded corner of the middle frame to squeeze the dust-free cloth 14 and abut against the second wiping surface 231; then, the moving module drives the middle frame to move along the inclined direction of the second wiping surface 231, so that the rounded corner on the middle frame can be tilted and moved on the part of the dust-free cloth 14 that abuts against the second wiping surface 231, so that the second wiping surface 231 wipes the rounded corner of the middle frame through the dust-free cloth 14 during the movement of the rounded corner.

[0081] Then, the moving module drives the side surface of the middle frame to move along the X-axis on the part of the dust-free cloth 14 that is in contact with the third wiping surface 232 and the first wiping surface 221, so that during the movement of the middle frame, the third wiping surface 232 and the first wiping surface 221 wipe the side surface of the middle frame through the dust-free cloth 14.

[0082] Afterwards, the moving module drives the middle frame to move and rotate along the X-axis and Y-axis until the next rounded corner on the middle frame rests against one side of the dust-free cloth 14, and then repeats the wiping process of the first wiping head 22 and the second wiping head 23 until all four sides and four rounded corners of the middle frame are wiped.

[0083] During the operation of the first wiping head 22 and the second wiping head 23 , the spray head 24 can continuously spray the wiping agent to the dust-free cloth 14 , so that the first wiping head 22 and the second wiping head 23 can wipe the center frame through the wet dust-free cloth 14 .

[0084] Then, the moving module drives the middle frame to move and rotate along the X-axis and the Y-axis until the side of the middle frame abuts against one side of the dust-free cloth 14. At the same time, the first driving member 21 drives one of the two third wiping heads 32, which is arranged close to the first wiping head 22, to move along the Y-axis to abut against the other side of the dust-free cloth 14. At this time, the side of the middle frame is located between the upper and lower finger wiping blocks 321 of the third wiping head 32. Afterwards, the moving module drives the middle frame and the dust-free cloth 14 along the Y-axis to squeeze between the two finger wiping blocks 321 and be able to move along the X-axis, so that the middle frame can perform the first wipe of the side and upper and lower surfaces of the middle frame through the dust-free cloth 14 during the movement between the two finger wiping blocks 321.

[0085] At this time, since the dust-free cloth 14 is in a dry state, the wiping agent remaining on the middle frame by the first wiping head 22 and the second wiping head 23 can be wiped off during the process of wiping impurities from the side and upper and lower surfaces of the middle frame, so that the middle frame wiped by the third wiping head 32 is not only clean but also in a dry state.

[0086] Then, the moving module drives the middle frame to move and rotate along the X-axis and Y-axis until the side of the middle frame abuts against one side of the dust-free cloth 14. At the same time, the second driving member 31 drives the other third wiping head 32 of the two third wiping heads 32 to move along the Y-axis to abut against the other side of the dust-free cloth 14. At this time, the side of the middle frame is located between the upper and lower finger wiping blocks 321 of the third wiping head 32; after that, the moving module drives the middle frame and the dust-free cloth 14 along the Y-axis to squeeze between the two finger wiping blocks 321 and be able to move along the X-axis, so that the middle frame can be wiped for the second time on the side and upper and lower surfaces of the middle frame by the dust-free cloth 14 during the movement between the two finger wiping blocks 321.

[0087] Finally, the wiping process of the two third wiping heads 32 is repeated until both the upper and lower surfaces on each side are wiped clean, thereby completing the entire wiping process of the centering frame.

[0088] Through the above wiping process, the middle frame is wet wiped and dry wiped respectively, and the wiping is repeated multiple times, so that the dirt and impurities on the surface of the middle frame can be effectively cleaned, so that the cleaning efficiency of the middle frame can reach more than 95%, and the wiping effect is better.

For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
