[0028] The technical solutions of the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the specification of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection requested by the present application.

[0029] In the description of the embodiments of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0030] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0031] See also Figures 1 to 3 A lens fixing tool provided in an embodiment of the present application includes: a base 10 and a plurality of rings 20; the plurality of rings 20 are arranged on the base 10 for fixing the lens 30; the plurality of rings 20 have different inner diameters and different outer diameters; the plurality of rings 20 can be detachably connected to form a concentric ring structure.

[0032] In the lens fixing tool provided in this embodiment, the lens 30 can be clamped on the concentric ring structure by bonding or adsorption. When clamping lenses 30 of different specifications, different numbers of rings 20 can be used so that the concentric ring structure can be set to different diameters as needed.

[0033] like Figure 3 and Figure 4 As shown, when assembling a small-sized lens 30, only one ring 20 can be used; when the lens 30 is processed and needs to be replaced with a large-sized lens 30, the small-sized lens 30 can be removed and the larger ring 20 can be sleeved on the smaller ring 20.

[0034] In a more specific embodiment, threads are provided on the outer circumference and the inner circumference of the collar 20; that is, in this embodiment, the plurality of collars 20 are detachably connected to each other by being threadedly connected to each other.

[0035] It should be noted that after the lens 30 is adsorbed or bonded to the ring 20, when the base 10 rotates at a high speed, in order to prevent the lens 30 from being displaced during the rotation process, Figure 5 As shown, after setting a ring 20 that matches the size of the lens 30, another ring 20 can be placed on the periphery of the lens 30, and the height of the outermost ring 20 can be made higher than the height of the ring 20 located on the inner side thereof, so that the outer periphery of the lens 30 can be limited and fixed by the outermost ring 20 to avoid displacement of the lens 30 and meet the eccentricity accuracy requirements during the processing.

[0036] In practical applications, in addition to processing the convex surface, the concave surface of the lens 30 also needs to be processed; Figures 6 to 8 As shown, the top surface of the concentric ring structure composed of a plurality of rings 20 can be provided with a concave surface so that the lens 30 can be placed with the concave surface facing upward.

[0037] In application, the top surface of the concentric ring structure can be set as a concave surface by, for example, adjusting the relative heights of adjacent rings 20 through the threaded structure on the ring 20 so that the top surface of the concentric ring structure forms a concave surface.

[0038] In one embodiment, see Figures 6 to 8 In the concentric ring structure provided in this embodiment, the heights of the plurality of rings 20 increase from the inside to the outside, so that the top surface of the concentric ring structure forms a concave surface.

[0039] In practical applications, the outer ring 20 may be 0.5-1 mm higher than the inner ring 20 .

[0040] It should be noted that if Figure 7 As shown, when the ring 20 clamps the lens 30 so that the concave surface of the lens 30 faces upward, another ring 20 can be inserted into the outer periphery of the lens 30 to fix the lens 30.

[0041] Furthermore, the top surface of the collar 20 is a plane.

[0042] Specifically, during the application process, the top surface of each ring 20 can be milled to form a flat surface, so that the lens 30 can be stably bonded and adsorbed.

[0043] When processing the rough lens, it can be clamped by adsorption; when processing the polished and coated lens, it is necessary to use bonding to avoid deformation of the lens caused by adsorption. The glue used for bonding is UV glue, and after bonding, it is irradiated with a UV lamp with a power of less than 30W.

[0044] For more specific examples, see Figure 1 The base 10 includes: a handle 11 and a support plate 12 ; the handle 11 is arranged below the support plate 12 ; and a plurality of collars 20 are arranged on the support plate 12 .

[0045] For further information, see Figure 4 and Figure 8 The base 10 is provided with an air suction hole 13 which penetrates in the vertical direction, and air is sucked from above the ring 20 through the air suction hole 13 to form a vacuum cavity for adsorbing the lens 30 .

[0046] The above are only preferred embodiments of the present application and are not intended to limit the present utility model. Although the present application has been described in detail with reference to the examples, those skilled in the art can still modify the technical solutions recorded in the aforementioned examples or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
