[0002] In related technologies, existing perovskite-based glass substrate cleaning machines use rollers with fixed spacing for limiting movement, which cannot adapt to glass substrates of different widths. When it is necessary to clean large-sized (e.g., 400mm*600mm) glass substrates, and at the same time want to clean medium-sized (e.g., 300mm*300mm or 400*400mm) glass substrates, multiple cleaning machines are generally required, which is costly.
[0003] Therefore, how to solve the problem of existing cleaning equipment being incompatible with glass substrates of different sizes is a technical problem that urgently needs to be solved in this field.
[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute information related to the technology. Utility Model Content

[0024] When cleaning the second-sized glass substrate, one floating limit roller on the right side separates from the fastening bolt, while the other floating limit roller on the left side is tightened to the fastening bolt. When cleaning the third-sized glass substrate, both floating limit rollers separate from the fastening bolt, so that the two ends of the third-sized glass substrate are respectively attached to the outer walls of the two fixed rollers.
[0025] In one optional embodiment, a plurality of drive rollers are fitted on the outer wall of the drive shaft, the outer diameter of which is the same as that of the fixed rollers;

[0051] Research has revealed that existing perovskite-based glass substrate cleaning machines can only clean one size of glass substrate and are not compatible with multiple sizes.

[0054] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0055] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0056] like Figures 1 to 5 As shown, at least one embodiment provides a conveyor roller for glass substrate 3-size compatibility, comprising:
[0057] A drive shaft 1 has several drive rollers 10 fitted onto its outer wall. A drive gear 13 is fitted onto one end of the drive shaft 1, and the drive gear 13 is connected to a drive motor (not shown in the attached drawing). The drive motor is adapted to drive the drive shaft 1 to rotate. Furthermore, there are multiple drive shafts 1, and the distance between two adjacent drive shafts 1 is less than the width of the first-sized glass substrate. (See attached drawing.) Figure 2 The adjustable limiting component 2 includes a fastening bolt 21 and a floating limiting roller 22. The floating limiting roller 22 is threadedly fitted to the fastening bolt 21. The fastening bolt 21 is fixed to the outer wall of the drive shaft 1. When the drive shaft 1 rotates, it drives the fastening bolt 21 to rotate synchronously. Furthermore, the outer diameter of the fastening bolt 21 is smaller than the outer diameter of the drive roller 10. When the drive roller 10 drives the glass substrate 3 to move horizontally, the fastening bolt 21 does not contact the glass substrate 3. The floating limiting roller 22 rotates relative to the fastening bolt 21, and is in a tightened or loosened state to adjust the axial distance between the floating limiting roller 22 and the fixed roller 11 to adapt to the glass substrate 3 of the corresponding size. By tightening or loosening the fastening bolt 21 and the floating limiting roller 22, the axial distance between the floating limiting roller 22 and the fixed roller 11 is adjusted to adapt to the glass substrate 3 of the corresponding size, improving the compatibility of the equipment.
[0058] Reference Appendix Figure 3 A fixed wheel 11 is fitted onto one end of the drive shaft 1, and the outer diameter of the fixed wheel 11 is the same as the outer diameter of the drive roller 10. A first limiting disc 12 is provided on the side of the fixed wheel 11 away from the fixed wheel 11 to limit the lateral movement of the glass substrate 3. The first limiting disc 12 is provided to limit the end wall of the glass substrate 3 when the drive roller 10 drives the glass substrate 3 to move horizontally, thereby preventing the glass substrate 3 from moving laterally during the movement.
[0059] Reference Appendix Figure 4 and Figure 5 The fastening bolt 21 has a spiral thread 23 on its outer wall, and the outer diameter of the fastening bolt 21 is smaller than that of the drive roller 10. The inner ring of the floating limiting roller 22 has a threaded groove 24 that matches the spiral thread 23, and the outer diameter of the floating limiting roller 22 is the same as that of the drive roller 10. The fastening bolt 21 has a fixed threaded hole 26 in the radial direction. After the bolt passes through the fixed threaded hole 26, it abuts against the drive shaft 1 to lock the axial position of the fastening bolt 21.
[0060] Reference Appendix Figure 5 A second limiting disc 25 is provided on the side of the floating limiting roller 22 away from the fixed roller 11. The second limiting disc 25 is adapted to limit the glass substrate 3. When the floating limiting roller 22 is tightened with the fastening bolt 21, both ends of the glass substrate 3 are limited by the first limiting disc 12 and the second limiting disc 25 respectively, preventing the glass substrate 3 from moving laterally during the movement.
[0061] The distance between the inner wall of the floating limiting roller 22 and the outer wall of the second limiting disk 25 is less than the radius of the driving roller 10. When the floating limiting roller 22 is detached from the fastening bolt 21, the transmission shaft 1 rotates relative to the floating limiting roller 22, and the floating limiting roller 22 is located below the glass substrate 3. Wherein, as... Figure 3 As shown, H1 represents the width of the first-size glass substrate; when cleaning the first-size glass substrate, the floating limiting roller 22 is tightened with the fastening bolt 21 to limit the glass substrate 3; in this embodiment, the first-size glass substrate 3 has a length and width of 300*300mm.
[0062] like Figure 2 As shown, H2 represents the width of the second-sized glass substrate; when cleaning the second-sized glass substrate, the floating limiting roller 22 separates from the fastening bolt 21, so that the drive shaft 1 rotates relative to the floating limiting roller 22. In this embodiment, the second-sized glass substrate 3 has a length and width of 400*600mm.
[0063] Reference Appendix Figures 6 to 8 At least one embodiment provides a conveying roller compatible with a third-size glass substrate, comprising: a drive shaft 1, with fixed wheels 11 respectively fitted at both ends, the distance between the two fixed wheels 11 being equal to that of the third-size glass substrate; two fastening bolts 21 respectively fitted onto the outer wall of the drive shaft 1; and two floating limiting rollers 22 respectively disposed on the same side of the fastening bolts 21 and threadedly adapted to the fastening bolts 21; as shown below. Figure 6 As shown, H1 represents the width of the first-size glass substrate; when cleaning the first-size glass substrate, a floating limiting roller 22 located on the right side is tightened with a fastening bolt 21; the two ends of the first-size glass substrate are respectively limited by the first limiting plate 12 and the second limiting plate 25.
[0064] like Figure 7 As shown, H2 represents the width of the second-sized glass substrate; when cleaning the second-sized glass substrate, a floating limiting roller 22 on the right side separates from the fastening bolt 21, and a floating limiting roller 22 on the left side is tightened to the fastening bolt 21; at this time, the second-sized glass substrate passes over a floating limiting roller 22 on the right side, and its end wall abuts against a second limiting disc 25 on the left side.
[0065] like Figure 8 As shown, H3 represents the width of the third-size glass substrate. When cleaning the third-size glass substrate, both floating limiting rollers 22 are separated from the fastening bolts 21, so that both ends of the third-size glass substrate are respectively attached to the outer walls of the two fixed rollers 11. In this embodiment, the length and width of the third-size glass are 600*600mm.
[0066] At least one embodiment provides a cleaning machine, including: a cleaning chamber, wherein the glass substrate 3 is dimensionally compatible and the conveying rollers are horizontally evenly distributed within the cleaning chamber.
