[0030] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. The drawings illustrate typical embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. It should be understood that the embodiments of this utility model and the specific features thereof are detailed descriptions of the technical solutions of this application, and not limitations thereof. Where there is no conflict, the embodiments of this utility model and the technical features thereof can be combined with each other.

[0031] Example 1

[0032] refer to Figures 1-2 The optical glass cleaning and fixing device of this utility model includes multiple sets of integrally molded roller structures 1. Specifically, the roller structure 1 is integrally molded using an injection molding process, resulting in a short processing time. The roller structure 1 is specifically made of rigid polyurethane foam (PU-R), with a smooth and flat surface that protects the glass surface and prevents scratches.

[0033] Multiple sets of roller structures 1 are arranged along the length of the glass, and each set of roller structures 1 specifically includes two roller structures 1, which are mirror images of each other along the width of the glass. In this embodiment, the glass is specifically mobile phone glass, which is rectangular. Of course, the glass can also be the glass of other electronic devices, such as flat glass.

[0034] The roller structure 1 is divided into two types: a first roller 11 and a second roller 12. (Comparison) Figure 4 and Figure 6 , Figure 7 The difference between the two is that the first roller 11 has a larger skirt 102 and the second roller 12 has no skirt 102 or a very small skirt 102.

[0035] refer to Figures 3-5 Taking the first roller 11 as an example, the roller structure 1 includes a roller body 101 and a support ring 103.

[0036] The roller body 101 is a cylinder. The edge of one end face of the roller body 101 extends outward along the radial direction of the roller body 101 to form the skirt 102. Thus, when the two roller bodies 101 are arranged in a mirror image facing each other, the skirts 102 of both can clamp the left and right long sides of the glass 3 from opposite directions.

[0037] One or more support rings 103 are provided on the peripheral wall of the roller body 101. If there are multiple support rings 103, they are spaced apart along the axial direction of the roller body 101, that is, arranged in the left-right direction. The support rings 103 are formed by protruding outward from the peripheral wall of the roller body 101 along the radial direction of the roller body 101.

[0038] Thus, multiple sets of roller structures 1 are arranged along the length of the glass to jointly support the glass using the support ring 103, and each set of roller structures 1 is mirror-image arranged along the width of the glass to jointly clamp the glass using the skirt 102. Since only the support ring 103 is in contact with the glass surface, the contact area with the glass is very small, making it less likely to scratch the glass. Moreover, the roller structure 1 can also roll with the glass, thus solving the existing problem of cleaning dead corners. In addition, the entire roller structure is integrally molded, which is simple to manufacture and does not require assembly, reducing production costs.

[0039] The support ring 103 can be a flat "O" ring. Preferably, it is an elliptical "O" ring, meaning the raised outline of the support ring 103 is elliptical (not a complete ellipse, but rather refers to a portion with elliptical curvature), which allows for line contact with the glass and further reduces the contact area. Of course, it can also be circular.

[0040] The skirt 102 of the first roller 11 protrudes in the radial direction relative to the roller body 101 by a dimension greater than the preset dimension of the glass thickness. The larger the preset dimension, the lower the possibility of the glass being thrown out. Therefore, the specific size of the preset dimension can be set according to the specific situation.

[0041] refer to Figure 6 In this embodiment, the main difference between the second roller 12 and the first roller 11 is that the second roller 12 does not have the skirt 102, meaning the second roller 12 only serves a supporting function. Of course, referring to... Figure 7 In other embodiments, the second roller 12 may also have a skirt 102, except that the radial dimension of the skirt 102 of the second roller 12 is much smaller than the radial dimension of the skirt 102 of the first roller 11, which can be compared. Figure 4 and Figure 7 The radial dimension of the skirt 102 of the second roller 12 can be determined by the radial dimension of the skirt 102 of the first roller 11.

[0042] The reason for distinguishing the second roller 12 from the first roller 11 in this embodiment is that if the skirt 102 is too small, it will not be able to hold the glass 3 during transport, making it prone to deviation and causing poor glass overlap. Moreover, if the support ring 103 wears unevenly, the glass may not be able to travel in a straight line during transport, and may drift into other slots, causing scratches after collision. Therefore, in this embodiment, the skirt 102 of the first roller 11 is made larger, exceeding 58mm, which makes the clamping of the glass 3 more reliable. Even if the elliptical "O"-shaped support ring 103 wears, it will not cause the glass to drift into other slots during transport, nor will it cause scratches. However, increasing the skirt 102 would necessarily mean that the gap between the two first rollers 11 would increase, which might make it impossible to arrange all the first rollers 11. Even if they could be arranged, the support strength for the glass 3 would be reduced. Therefore, this embodiment proposes to use the second roller 12 to fill the gap. Specifically, the left and right roller structures 1 of the same group are of the same type, but the two adjacent groups of roller structures 1 are of different types.

[0043] Continue to refer to Figures 1-2 The optical glass cleaning and fixing device in this embodiment also includes a connecting shaft 2. A shaft hole 1011 for inserting the connecting shaft 2 is formed axially inside the roller body 101. This allows the connecting shaft 2 to be installed into the shaft hole 1011, and controlling the rotation of the connecting shaft 2 will cause the roller body 101 to rotate together. To ensure synchronous rolling, the roller structures 1 in the same group are connected to the same connecting shaft 2. The connecting shaft 2 is connected to the motor of the cleaning machine.

[0044] To secure the connecting shaft 2 and the shaft hole 1011, in this embodiment, when the roller structure 1 is integrally molded using injection molding, the shaft hole 1011 is formed with a draft angle so that it can be clamped together with the connecting shaft 2 during assembly. For example, the shaft hole 1011 with a diameter of 10mm has a draft angle of 1 degree. Figure 4 , 6 The two dotted lines in 7 represent the shaft hole 1011, which is inclined. The end near the skirt 102 has a larger diameter and the other end has a smaller diameter. In this way, after inserting the connecting shaft 2 from the end near the skirt 102, it is not necessary to use screws to tighten it.

[0045] Of course, to ensure reliable connection and prevent slippage, the connecting shaft 2 can also be fixed with screws. Alternatively, at least one locking hole 1012 for mounting screws to lock the connecting shaft 2 can be provided on the roller body 101. The locking hole 1012 is located on the peripheral wall of the roller body 101 and extends radially along the roller body 101 to communicate with the connecting shaft 2. For example, in this embodiment, two support rings 103 and two locking holes 1012 are provided on the peripheral wall of the roller body 101. The two support rings 103 are respectively located near both ends of the roller body 101, and the locking holes 1012 are located between the two support rings 103. The two locking holes 1012 are vertically aligned with respect to the central axis of the roller body 101.

[0046] Example 2

[0047] refer to Figure 8 The difference between this embodiment and Embodiment 1 is that two sets of first rollers 11 and one set of second rollers 12 are provided. The set of second rollers 12 is located between the two sets of first rollers 11. Depending on the size of the glass product, the size and / or number of the first rollers 11 and second rollers 12 can be further adjusted.

[0048] In summary, the optical glass cleaning and fixing device and optical glass cleaning machine of this utility model have the following beneficial effects: This utility model adopts a multi-roller structure, the roller structure including the roller body, skirt, and support ring. The multiple roller structures are arranged along the length direction of the glass so that the support ring can jointly support the glass. Each roller structure is mirrored along the width direction of the glass so that the skirt can jointly clamp the glass. In this way, the contact surface with the glass is very small, and it is not easy to scratch the glass. Moreover, the entire roller structure is integrally molded, which is simple to manufacture and does not require assembly, thus reducing production costs. Furthermore, the raised contour of the support ring is elliptical, which can achieve line contact with the glass. The rollers of this utility model are also differentiated by type. The larger the skirt, the more reliable the clamping. The problem of excessive gaps between roller structures with large skirts can be filled by roller structures with small skirts or no skirts. Therefore, while improving clamping reliability, the support strength is guaranteed. The one-piece molding process using injection molding, and the shaft hole is demolded with a draft angle, will clamp more tightly when assembled with the connecting shaft, avoiding slippage.
