Further, as shown in fig. 1-3, the second wiper assembly includes a second driver 31 and a third wiper head 32; wherein, the fixed end of the second driving piece 31 is arranged on the supporting frame 1, and the driving end of the second driving piece 31 is in driving connection with the third wiping head 32; the third wiping head 32 comprises two finger wiping blocks 321 which are oppositely arranged in the vertical direction, the two finger wiping blocks 321 can be mutually close to or far away from each other, the second driving piece 31 is used for simultaneously driving the two finger wiping blocks 321 to move along the Y axis to one side abutting against the dust-free cloth 14, the moving module can drive the middle frame to move to the other side abutting against the dust-free cloth 14 and is opposite to the two finger wiping blocks 321, and the moving module can also drive the middle frame and the dust-free cloth 14 to squeeze between the two finger wiping blocks 321 along the Y axis and move along the X axis, so that the two finger wiping blocks 321 can form a part which is clamped between the upper surface and the lower surface of the middle frame in a finger clamping structure, at the moment, the dust-free cloth 14 is wrapped on the middle frame, and then the moving module drives the middle frame to move along the X axis between the two finger wiping blocks 321, thereby realizing wiping of the side surface and the upper surface and the lower surface of the middle frame. In this embodiment, the second driving member 31 is specifically a cylinder.

The two finger wiping blocks 321 can form a structure that the upper surface and the lower surface of the middle frame are clamped by the finger clamping structure, so that the two finger wiping blocks 321 can wipe the side surface of the middle frame through the dust-free cloth 14 at the same time, and impurities on the side surface of the middle frame can be wiped for the second time so as to wipe the side surface of the middle frame cleanly; on the other hand, the residual wiping agent on the side surface of the middle frame can be wiped off, so that water stains can not be formed on the side surface of the middle frame; meanwhile, as the two finger wiping blocks 321 can wipe the upper and lower surfaces of the middle frame in a manner of clamping the upper and lower surfaces of the middle frame through the dust-free cloth 14, impurities on the upper and lower surfaces of the middle frame can be wiped clean well; meanwhile, the wiping agent splashed to the upper surface and the lower surface of the middle frame can be wiped, so that water stains are not formed on the upper surface and the lower surface of the middle frame, and the middle frame is ensured to be in a dry state.

Specifically, the number of the third wiping heads 32 may be set to be plural so that the center frame can be wiped plural times by the plural third wiping heads 32 to make the wiping effect better. In this embodiment, as shown in fig. 1 to 3, two third wiping heads 32 are provided, and the two third wiping heads 32 are disposed at intervals, so as to wipe the upper and lower sides of the center frame twice in front and back, thereby further ensuring the wiping effect of the center frame. In order to save the number of driving members and to reduce the space for arranging the driving members, one of the two third wiping heads 32 is in driving connection with the first driving member 21, and the other third wiping head 32 is in driving connection with the second driving member 31, and is not limited thereto, as long as it is ensured that the first wiping head 22, the second wiping head 23, and the third wiping head 32 are moved to the side abutting against the dust-free cloth 14 by the respective driving members.

It should be noted that, since the dust-free cloth 14 has a certain elasticity, the first wiping head 22, the second wiping head 23 and the third wiping head 32 can all be abutted against one side of the dust-free cloth 14 by setting specific positions of the guide rollers 5 on the support frame 1 and controlling the driving of the first driving member 21 and the second driving member 31, so that the wiping of the center frame is facilitated.

The base plate 322 is provided with a rotating rod 325, one end of the rotating rod 325 is fixedly connected with the base plate 322, and the other end of the rotating rod 325 is rotatably connected with the finger wipe 321, so that the finger wipe 321 can rotate around the rotating rod 325 relative to the base plate 322.

The two finger wiping blocks 321 are mutually close to each other through 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 wiping blocks 321, and therefore when the middle frame moves between the two fourth wiping surfaces 3211, the two finger wiping blocks 321 can generate mutually close extrusion force on the upper surface and the lower surface of the middle frame, the pressing effect of the two finger wiping blocks 321 on the middle frame is good, and impurities on the upper surface and the lower surface of the middle frame can be easily wiped off when the middle frame moves between the two fourth wiping surfaces 3211.

Further, as shown in fig. 4, the third wiping head 32 further includes an adjusting block 324, the adjusting block 324 is fixedly disposed on the base plate 322, the two finger wiping blocks 321 are respectively located at two 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, and the adjusting block 324 is used for adjusting a gap distance between the two finger wiping blocks 321 when not pressed by the middle frame, so that the gap distance is smaller than 0.2mm-0.4mm of the thickness of the middle frame, and the gap distance is specifically a relative distance between two fourth wiping surfaces 3211 on the upper and lower finger wiping blocks 321.

The gap distance is smaller than 0.2mm-0.4mm of the thickness of the middle frame, so that the middle frame can be extruded between the two finger rubbing blocks 321 with force, but the middle frame can be ensured to be easier to extrude between the two finger rubbing blocks 321, the middle frame cannot be worn in the extrusion process, and the middle frame can be better protected. In this embodiment, the gap distance is less than 0.2mm of the thickness of the center frame.

Specifically, as shown in fig. 4, a first inclined surface 3212 is formed on the finger wipe block 321 on a side close to the adjustment block 324, the first inclined surface 3212 and the fourth wiping surface 3211 are located on the same side of the finger wipe block 321, and a second inclined surface 3241 is formed on the adjustment block 324; when the middle frame is not extruded between the two finger rubbing blocks 321, the first inclined plane 3212 is completely attached to the second inclined plane 3241, and the connection part between the first inclined plane 3212 and the fourth rubbing surface 3211 abuts against the second inclined plane 3241, so that the connection part between the first inclined plane 3212 and the fourth rubbing surface 3211 can limit the first inclined plane 3212 to further slide on the second inclined plane 3241 under the action of the tension spring 323, so that the two finger rubbing blocks 321 are limited to further approach each other under the action of the tension spring 323, and at the moment, the interval between the two fourth rubbing surfaces 3211 on the two finger rubbing blocks 321 is the gap distance.

It should be noted that, the size of the gap distance can be controlled by adjusting the specific abutting 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 with different thicknesses, and the universality of the wiping device is better.

When the middle frame is extruded between the two finger rubbing blocks 321, the finger rubbing blocks 321 can rotate around the rotating rod 325 under the extrusion action of the middle frame, at the moment, the first inclined plane 3212 and the second inclined plane 3241 are separated from each other, and one end of the first inclined plane 3212 can smoothly slide on the second inclined plane 3241, so that the two finger rubbing blocks 321 are far away from each other; when the middle frame moves out of the two finger rubbing blocks 321, the two finger rubbing blocks 321 can rotate around the rotating rod 325 to approach each other under the action of the tension spring 323, and when the middle frame rotates to the condition that the first inclined surface 3212 is completely attached to the second inclined surface 3241 and the connection part between the first inclined surface 3212 and the fourth inclined surface 3211 abuts against the second inclined surface 3241, the two finger rubbing blocks 321 can not rotate continuously to approach each other again under the action of the tension spring 323, so that the distance between the two finger rubbing blocks 321 is reset to the initial gap distance.

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