[0002] Before processing, the glass substrate needs to be cleaned by a cleaning machine. In order to prevent the glass substrate from shifting during the cleaning process, pressure rollers are usually set to press it tightly.
[0003] In related technologies, existing cleaning machines require manual adjustment of the height of the pressure rollers when cleaning glass substrates to adapt to the thickness of the glass substrate and achieve appropriate clamping force. However, when the thickness of the glass substrate changes, the pressure rollers may detach from the glass substrate or the clamping force on the glass substrate may surge, making it difficult for the glass substrate to pass through the pressure rollers, thus requiring readjustment of the height of the pressure rollers.
[0004] Therefore, how to solve the technical problem that the pressure rollers of existing cleaning machines are difficult to adapt to glass substrates of various thicknesses is a problem that urgently needs to be solved by those skilled in the art.
[0005] 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 prior art information. Utility Model Content

Detailed Implementation
[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] 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.
[0025] like Figure 1 , Figure 2 As shown, at least one embodiment provides an elastic clamping device for a cleaning machine, including: a pair of mounting blocks 1; a rotating shaft 2, the two ends of which are rotatably connected to the corresponding mounting blocks 1, and one end of the rotating shaft 2 is provided with an input gear 21; at least two floating pressure roller mechanisms 3, each sleeved on the rotating shaft 2, for clamping the substrate on the conveying mechanism, and including: a spring 31, a floating roller 32 and a pair of limiting components 33.
[0026] Specifically, spring 31 is mounted on shaft 2.
[0027] Specifically, the floating roller 32 is mounted around the spring 31.
[0028] Specifically, both limiting components 33 are mounted on the rotating shaft 2 and sleeved on the corresponding ends of the spring 31. By adjusting the distance between the two limiting components 33, the spring 31 is compressed, so that the middle part of the spring 31 expands outward to abut against the inner wall of the roller 32, thereby limiting the floating roller 32 on the spring 31 to rotate with the spring 31.
[0029] In this embodiment, during use, the elastic clamping device keeps the floating roller 32 in a pre-clamped state. That is, when the floating roller 32 clamps the glass substrate, the middle of the spring 31 has a certain radial bending, which generates downward pressure. When the thickness of the glass substrate changes, the floating roller 32 will adjust its floating amplitude radially, so that the glass substrate can pass through. When facing glass substrates within a certain thickness range, the floating roller 32 does not need to be manually adjusted in height, as it can be adaptively adjusted, which greatly improves the cleaning efficiency.
[0030] In some embodiments, optionally, the floating roller 32 can accommodate glass substrates ranging in size from 0.7 to 3.2 mm.
[0031] like Figure 1 , Figure 2As shown, in some embodiments, an annular mounting groove 321 is provided in the middle of the floating roller 32; wherein a washer 34 is provided in the annular mounting groove 321; the diameter of the washer 34 is larger than the diameter of the floating roller 32.
[0032] In this embodiment, a washer 34 is used instead of a floating roller 32 to contact the glass substrate, so that only the washer 34 needs to be replaced after wear, and the floating roller 32 does not need to be replaced.
[0033] like Figure 2 As shown, in some embodiments, the limiting component 33 includes: a spring limiting cap 331; wherein the spring limiting cap 331 is sleeved on the rotating shaft 2; one end of the spring limiting cap 331 is a limiting end 3312, which is used to sleeve on the corresponding end of the spring 31.
[0034] In this embodiment, a spring limit cap 331 is used to limit the position of the spring 31 so that the spring 31 remains coaxial with the rotating shaft 2.
[0035] like Figure 2 As shown, in some embodiments, the limiting component 33 further includes a fixing ring 332; wherein the other end of the spring limiting cap 331 is a fixing end 3311; the fixing ring 332 is sleeved on the fixing end 3311 and is suitable for fixing the spring limiting cap 331 on the rotating shaft 2 by locking the connector.
[0036] In this embodiment, the function of the retaining ring 332 is to fix the spring limiting cap 331 on the rotating shaft 2. By opening a notch, the connecting piece connects the two sides of the notch, thereby adjusting the inner diameter of the retaining ring 332 so that the spring limiting cap 331 is fastened on the rotating shaft 2.
[0037] like Figure 2 As shown, in some embodiments, an annular limiting groove 3313 is provided on the end face of the limiting end 3312; wherein the end of the spring 31 is disposed in the annular limiting groove 3313.
[0038] In this embodiment, since the inner diameter of the spring 31 is larger than that of the rotating shaft 2, the use of the annular limiting groove 3313 can prevent the end of the spring 31 from undergoing radial deformation, which would lead to a decrease in the concentricity between the spring 31 and the rotating shaft 2.
[0039] like Figure 2 As shown, in some embodiments, a mounting hole 3314 is provided at the center of the spring limit cap 331; wherein the spring limit cap 331 is sleeved on the rotating shaft 2 through the mounting hole 3314.
[0040] In this embodiment, the mounting hole 3314 is clearance-fitted with the rotating shaft 2, thereby improving the coaxiality of the spring limit cap 331 and the rotating shaft 2.
[0041] At least one embodiment also provides a floating pressure roller mechanism, including: a spring 31 sleeved on a rotating shaft 2; a floating roller 32 sleeved around the spring 31; and a pair of limiting components 33 respectively sleeved on corresponding ends of the spring 31; wherein the two limiting components 33 are adapted to keep the spring 31 in a compressed state by adjusting the distance between them, and to make the spring 31 abut against the inner wall of the floating roller 32; the floating roller 32 is adapted to drive the middle part of the spring 31 to bend radially when subjected to force to adapt to substrates of different thicknesses.
[0042] Specifically, both limiting components 33 are mounted on the rotating shaft 2 and sleeved on the corresponding ends of the spring 31. By adjusting the distance between the two limiting components 33, the spring 31 is compressed, so that the middle part of the spring 31 expands outward to abut against the inner wall of the roller 32, thereby limiting the floating roller 32 on the spring 31 to rotate with the spring 31.
[0043] In this embodiment, during use, the floating roller mechanism keeps the floating roller 32 in a pre-compression state. That is, when the floating roller 32 presses against the glass substrate, the middle part of the spring 31 has a certain radial bending, thereby generating downward pressure. When the thickness of the glass substrate changes, the floating roller 32 will adjust its floating amplitude radially, so that the glass substrate can pass through. When facing glass substrates within a certain thickness range, the floating roller 32 does not need to be manually adjusted in height, as it can be adaptively adjusted, greatly improving cleaning efficiency.
[0044] In some embodiments, an annular mounting groove 321 is provided in the middle of the floating roller 32; wherein a washer 34 is provided in the annular mounting groove 321; the diameter of the washer 34 is larger than the diameter of the floating roller 32.
[0045] In this embodiment, a washer 34 is used instead of a floating roller 32 to contact the glass substrate, so that only the washer 34 needs to be replaced after wear, and the floating roller 32 does not need to be replaced.
[0046] In some embodiments, the limiting component 33 includes: a spring limiting cap 331 and a retaining ring 332; wherein the spring limiting cap 331 has a mounting hole 3314 at its axial center, suitable for being sleeved on the rotating shaft 2 through the mounting hole 3314; one end of the spring limiting cap 331 is a limiting end 3312, and an annular limiting groove 3313 for sleeved on the end of the spring 31 is provided on the end face of the limiting cap 331; the other end of the spring limiting cap 331 is a retaining end 3311, and the retaining ring 332 is sleeved on the retaining end 3311, suitable for fixing the spring limiting cap 331 on the rotating shaft 2 by locking the connecting member.
[0047] Specifically, a spring limit cap 331 is used to limit the position of the spring 31, so that the spring 31 remains coaxial with the rotating shaft 2.
[0048] Specifically, the function of the retaining ring 332 is to fix the spring limiting cap 331 on the rotating shaft 2. By opening a notch, the connecting piece connects the two sides of the notch, thereby adjusting the inner diameter of the retaining ring 332 so that the spring limiting cap 331 is fastened on the rotating shaft 2.
[0049] Specifically, since the inner diameter of spring 31 is larger than that of shaft 2, an annular limiting groove 3313 is used to prevent radial deformation of the end of spring 31, which would lead to a decrease in the concentricity between spring 31 and shaft 2. Specifically, the mounting hole 3314 is clearance-fitted with the rotating shaft 2, thereby improving the coaxiality of the spring limit cap 331 and the rotating shaft 2.
[0050] At least one embodiment also provides a cleaning machine, including: a conveying mechanism; and an elastic clamping device for the cleaning machine; wherein the elastic clamping device is disposed above the conveying mechanism and is adapted to clamp a substrate on the conveying mechanism.
[0051] For the specific structure and implementation process of the elastic clamping device for the cleaning machine, please refer to the relevant discussion in the above embodiments, and will not be repeated here.
[0052] In summary, this cleaning machine utilizes an elastic clamping device, a floating pressure roller mechanism, and a pre-clamped state for the floating roller 32 during operation. Specifically, when the floating roller 32 presses against the glass substrate, the middle of the spring 31 experiences a certain radial bending, generating downward pressure. When the thickness of the glass substrate changes, the floating roller 32 adjusts its floating amplitude radially, allowing the glass substrate to pass through. Furthermore, when dealing with glass substrates within a certain thickness range, the floating roller 32 does not require manual height adjustment; it can adaptively adjust, significantly improving cleaning efficiency.
