Of course, the number of conveying rollers can be appropriately set according to actual conditions. The gap3is provided to facilitate the corresponding cleaning of the lower surface of the glass substrate to be cleaned on the conveying roller in the cleaning assembly.

At the same time, the first roller41and the second roller42are disposed on two opposite sides of the rack1respectively, so that the glass substrate can receive a more uniform force, and can cooperate with the rotation of the conveying roller to jointly push the glass substrate to move, so that the upper and lower surfaces of the glass substrate are cleaned by the cleaning assembly simultaneously.

In addition, the first roller41is fixed on the first connecting rod43, the second roller42is fixed on the second connecting rod44, and the first connecting rod43and the second connecting rod44may move along the axial direction of the conveying roller2, so that the distance between the first connecting rod43and the second connecting rod44can be adjusted, thereby adjusting the distance between the first roller41and the second roller42accordingly. That is, the distance between the first connecting rod43and the second connecting rod44can be adjusted according to the size of the glass substrate, so that the glass substrate can be more steady in moving in the direction in which the conveying roller rotates under the action of the first roller41and the second roller42and achieve the purpose of cleaning.

In particular, the first connecting rod and the second connecting rod can both move along the axial direction of the conveying roller, so that the distance between the first connecting rod and the second connecting rod is adjustable, thereby enabling adaptation and cleaning of the glass substrates of different sizes.

In some embodiments, the limiting assembly4further includes a first limit wheel45located on the first connecting rod43and driven by the driving device5and a second limit wheel46located on the second connecting rod44.

Specifically, the first limit wheel45and the second limit wheel46can ensure that the glass substrate can keep moving in a certain direction when it is conveyed and cleaned, for avoiding the deviation of the conveying direction of the glass substrate. It is more conducive to the entire conveying, reducing needless bothers and improving the efficiency of cleaning. Without doubt, the first limit wheel45and the second limit wheel46can also be directly and movably fixed to the rack1according to actual conditions.

For the limiting assembly, the number of the first rollers and the second rollers and the positional relationship of the first rollers and the second rollers may be set to balance the external force applied to the glass substrates during the rotation, for conveying the glass substrates smoothly. Without doubt, the limiting component4can include four pairs of first roller41and second roller42, the first rollers41are evenly spaced, the second rollers42are evenly spaced, and the first rollers41face the second rollers42. Of course, it is also possible to set different numbers of first rollers41and second rollers42within the range allowed by the rack, the first rollers41are evenly spaced, the second rollers42are evenly spaced, and the first rollers41are opposite to second rollers42. The more the first and second rollers41,42that are evenly spaced in opposite directions, the better the glass substrates may be conveyed.
