Furthermore, the terms "first," "second," and the like, are used merely for distinguishing between descriptions and not for distinguishing between them.

The present embodiment discloses a wiping apparatus for wiping a glass substrate, as shown in fig. 1 and 2, the wiping apparatus including a frame 1, a wiping belt 7, a dry wiping head 5, and a carrier for carrying the glass substrate; the frame 1 is sequentially provided with an unreeling roller 2, a plurality of driving rollers 3 and a wind-up roller 4, the wiping strip 7 is unreeled by the unreeling roller 2, is conveyed by the plurality of driving rollers 3 and is wound by the wind-up roller 4, and the wiping strip 7 can select a plurality of wiping base materials which are not easy to stretch.

The dry wiping head 5 is arranged above the middle section of the conveying path of the wiping belt 7 and is used for pressing the wiping belt 7 downwards so as to enable the wiping belt 7 to move downwards to a wiping position (the wiping position is shown as a dotted line position in fig. 2) to contact with the glass substrate carried by the carrier; the carrier or frame 1 is translatable in at least one horizontal direction; the wiping device further comprises an elastic tensioning mechanism 6, the elastic tensioning mechanism 6 comprises a tensioning roller 65 and an elastic assembly, the tensioning roller 65 is connected on the frame in a sliding manner, and when the tensioning roller 65 is at one end of the sliding travel, the tensioning roller can tension the wiping belt at the wiping position; the elastic component is arranged between the frame 1 and the tensioning roller 65, and the elastic component can provide elastic force for the tensioning roller 65 so as to enable the tensioning roller 65 to return to the other end of the sliding stroke and tension and return the wiping belt 7 when the dry wiping head 5 moves upwards to return.

The end of the sliding travel of the tensioning roller 65 and the end of the sliding travel of the tensioning roller 65, which is reset to the other end of the sliding travel of the tensioning roller 65, are not absolute, and one end and the other end of the wiping belt 7 are tensioned and reset, only the fact that the dry wiping head 5 can store energy by an elastic component in the pressing process is required, and the tensioning roller 65 enables the wiping belt 7 to be in a tensioned state under the action of the elastic component in the moving process of the dry wiping head 5.

The driving device of the carrier can control the carrier to move towards one direction, at the moment, the length of the dry wiping head 5 is required to be larger than or equal to the width of the glass substrate, the driving device of the carrier can also control the carrier to move towards two directions, at the moment, the width of the glass substrate to be wiped can be larger than the length of the dry wiping head 5, and in addition, the carrier can move towards two directions, so that the situation that the periphery of some glass substrates is blocked can be aimed.

Further, as shown in fig. 3 and 4, the elastic tensioning mechanism 6 compensates the wiping belt 7 between the dry wiping head 5 and the unreeling roller 2 to be between the dry wiping head 5 and the wind-up roller 4 in the process of pressing down the dry wiping head 5, it can be understood that under the action of the elastic tensioning mechanism 6, the wiping belt 7 between the dry wiping head 5 and the unreeling roller 2 continues to move under the condition that the unreeling roller 2 and the wind-up roller 4 are not moved until the wiping belt 7 below the dry wiping head 5 is contacted with the glass substrate, in addition, after the wiping is completed, the dry wiping head 5 is far away from the wiping belt 7, and the wiping belt 7 is driven to be restored to a state of being not contacted with the dry wiping head 5 under the action of the elastic tensioning mechanism 6.

With the wiping apparatus disclosed in this embodiment, a section of the wiping belt 7 can be controlled to contact with the glass substrate in a state where the unwinding roller 2 and the winding roller 4 are stationary, and when the next glass substrate to be wiped is replaced, the wiping belt 7 can be controlled to move forward by rotating the winding roller 4, the wiping belt 7 that has been contaminated can be moved to a position below the dry wiping head 5 or between the dry wiping head 5 and the winding roller 4, and when wiping is repeated, the dry wiping head 5 moves forward the contaminated wiping belt 7 under the action of the elastic tensioning mechanism 6, and the clean wiping belt 7 contacts with the glass substrate to be wiped, and wipes it.

Further, as shown in fig. 3 and 4, the elastic component includes a fixed block 61, the fixed block 61 is disposed on the frame 1, a guide rod 62 is disposed on the fixed block 61, a sliding block 63 is slidably connected on the guide rod 62, a spring 64 sleeved on the guide rod 62 is disposed between the sliding block 63 and the fixed block 61, a tensioning roller 65 is rotationally connected on the sliding block 63, and the tensioning roller 65 is guaranteed to be tangent to the wiping belt 7 under the action of the reset force of the spring 64. In the process of pressing down the wiping belt 7, the wiping belt 7 positioned between the dry wiping head 5 and the unreeling roller 2 compresses the spring 64 to enable the tension roller 65 to approach the dry wiping head 5, so that the wiping belt 7 positioned between the dry wiping head 5 and the unreeling roller 2 is conveyed between the winding roller 4 and the dry wiping head 5, and damage to the wiping belt 7 is avoided. After the dry wiping head 5 is far away from wiping, the downward pressure applied to the wiping belt 7 disappears, and the wiping belt 7 is reset.

Further, when selecting the spring 64, it should be ensured that the spring 64 can contract when the dry erase head 5 is depressed. In addition, the elastic force of the spring 64 can be adjusted by the hoop sleeved on the guide rod 62.

Further, in order to avoid downward deflection of the end of the guide bar 62 away from the fixed block 61 due to the weight of the tension roller 65 and the slider 63, two slide rails 66 are provided on the frame 1, and the slider 63 can be slidably connected to both slide rails 66.

Further, a limit hole matched with the slide block 63 is formed in the frame 1, the slide block 63 is slidably connected in the limit hole, and the length direction of the limit hole is consistent with the length direction of the guide rod 62, so that the slide block 63 can be prevented from falling off from the guide rod 62.

Further, as shown in fig. 2, the wiping strip 7 is fed out from the unreeling roller 2, is tangent to the tensioning roller 65 after feeding out, and is then fed to the reeling roller 4 via a plurality of driving rollers 3, preferably the driving rollers 3 located at both sides of the dry wiping head 5 are at the same height.

Further, in order to avoid that the pushing down cylinder 92 is too fast in the descending process, which causes breakage of the wiping belt 7, a buffer assembly is arranged between the end part of the pushing down cylinder 92 and the dry wiping head 5, and the buffer assembly can avoid that the pushing down force of the pushing down cylinder 92 directly acts on the wiping belt 7. The buffer assembly comprises an upper bracket, a buffer spring 94 and a lower bracket, wherein the upper bracket is fixed at the extending end of the lower pressure cylinder 92, the lower bracket is fixed at the top of the dry wiping head 5, and the buffer spring 94 is arranged between the upper bracket and the lower bracket. After the lower pressure cylinder 92 moves downwards, when the dry wiping head 5 is just contacted with the wiping belt 7, the lower pressure of the lower pressure cylinder 92 firstly acts on the buffer spring 94 to enable the buffer spring 94 to shrink, the lower pressure acting on the wiping belt 7 under the action of the buffer spring 94 is reduced, and the fact that the wiping belt 7 breaks due to too large acting force of the lower pressure cylinder 92 is avoided.

In order to further detect the magnitude of the downward pressure cylinder 92, a pressure sensor may be further disposed at the extending end of the downward pressure cylinder 92, where the pressure sensor can detect the change condition of the downward pressure cylinder 92 during the process of just touching the wiping belt 7 and driving the wiping belt 7 to press down by the dry wiping head 5 and during the upward movement of the dry wiping head 5. It will be appreciated that the pressure sensor is of an existing construction and is not particularly limited in this embodiment.

Further, the wiping device further comprises an alcohol spraying mechanism 10, the alcohol spraying mechanism 10 being configured to adhere alcohol to the wiping strip 7 between the dry wiping head 5 and the unwind roller 2. The alcohol spraying mechanism 10 includes an alcohol spray head and an alcohol pot, the alcohol spray head sprays alcohol in the alcohol pot onto the wiping belt 7. It will be appreciated that the spraying mechanism is of conventional construction and is not particularly limited in this embodiment.
