Description

Technical Field

[0001] The utility model relates to the technical field of spectacle lens coating, in particular to a clamping device for anti-fog spectacle lens coating. Background Technique

[0002] There are two reasons for the lens to fog up: one is the liquefaction phenomenon caused by the relatively hot gas inside the lens encountering the relatively cold lens; the other is the evaporation of the moisture on the skin surface sealed by the glasses, and the gas condenses on the lens, which is also the main reason why the anti-fog agent doesn't work.

[0003] For example, the application number is 202120299351.2. The utility model provides a clamping device for anti-fog spectacle lens coating, which relates to the field of spectacle lens coating. The clamping device for anti-fog spectacle lens coating includes a clamping frame, and clamping mechanisms are arranged on both sides of the clamping frame. The clamping mechanism includes a clamping part, the clamping part is arranged inside the clamping frame, a clamping groove is opened on one side of the clamping part close to the center of the clamping frame, a round rod is fixedly connected to the side of the clamping part far from the center of the clamping frame, a through hole is opened on the clamping frame, a limiting sleeve is fixedly connected inside the clamping frame, and a fixing ring is fixedly sleeved on the outer side of the round rod. Due to the setting of the bearing seat, the round rod will not rotate, which will not affect the clamping effect of the clamping part on the lens. Instead, it can adjust the relative position of the clamping part to clamp different sizes of spectacle lenses, and can perform fine adjustment before or after clamping the lens, so that the clamping effect is better. However, when clamping the lens, this spectacle lens clamping device is not convenient for quickly clamping the lens, and when clamping the lens, it is not convenient to avoid damaging the lens due to excessive clamping force, and it is not convenient to flexibly adjust the placement angle of the lens after the lens clamping is completed.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a clamping device for anti-fog spectacle lens coating is proposed. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Such as Figure 1 - Figure 2As shown in the figure, a clamping device for coating an anti-fog glasses lens includes an installation ring 1 and a spring three 16. A first slide rail 2 is provided around the installation ring 1, and the cross-section of the first slide rail 2 is T-shaped. The side of the first slide rail 2 away from the center of the installation ring 1 is a frosted surface, and the side of the first slide rail 2 close to the center of the installation ring 1 is a smooth surface. A friction block 3 is slidably arranged inside the first slide rail 2, and both sides of the friction block 3 are respectively a frosted surface and a smooth surface. The frosted surface of the friction block 3 contacts the frosted surface inside the first slide rail 2. When coating the lens, first push the push rod 4 inward to make the friction block 3 away from the first slide rail 2. In this way, the installation ring 1 can rotate inside the bracket 5, and the installation ring 1 can also rotate around the center of the push rod 4, so that the installation ring 1 can rotate flexibly during coating;

[0024] Further, the first spring 6 can push the friction block 3 against the inner wall of the first slide rail 2, so as to fix the installation ring 1.

[0025] Further, the inner wall of the first slide rail 2 on the side away from the center is a frosted surface. In this way, the friction between the first slide rail 2 and the friction block 3 can be increased.

[0026] Such as Figure 2 - Figure 4As shown in the figure, a push rod 4 is fixedly arranged in the middle of one side of the friction block 3, and the push rod 4 is simultaneously rotatably connected to the mounting ring 1. A bracket 5 is rotatably arranged around the push rod 4, and the bracket 5 is arranged in an 'n' shape. Two friction blocks 3 are symmetrically arranged along the center line of the mounting ring 1. A first spring 6 is fixedly arranged around the push rod 4, and the other end of the first spring 6 is fixedly connected to the bracket 5. A sleeve 7 is fixedly arranged at the outer end of one side of the mounting ring 1, and two sleeves 7 are symmetrically arranged along the center line of the mounting ring 1. A second spring 8 is fixedly arranged at one end inside the sleeve 7, and the other end of the second spring 8 is fixedly arranged with a sliding rod 9. The sliding rod 9 is simultaneously connected to the sleeve 7, and chutes 10 are opened at both the upper and lower ends of the sleeve 7. Rack bars 11 are fixedly arranged at both the upper and lower ends of the sliding rod 9, and the rack bars 11 are simultaneously slidably connected to the chutes 10. Elastic elements 12 are arranged on both sides above the rack bars 11. The elastic elements 12 are located inside the mounting ring 1. The lower end of the elastic element 12 is fixedly connected to the mounting ring 1, and four groups of elastic elements 12 are symmetrically arranged along the center line of the mounting ring 1, with two in each group. The other end of the elastic element 12 is fixedly arranged with a handle 13. A latch 14 is fixedly arranged in the middle of the handle 13 near one end of the elastic element 12. The latch 14 is simultaneously slidably connected to the rack bar 11. The end of the sliding rod 9 away from the second spring 8 is fixedly arranged with a mounting bracket 15, and the mounting bracket 15 is arranged in an arc shape. Two mounting brackets 15 are symmetrically arranged along the center line of the mounting ring 1. A third spring 16 is fixedly arranged inside the mounting bracket 15 near one end of the second spring 8. The other end of the third spring 16 is fixedly connected to the second slide rail 17, and the cross-section of the second slide rail 17 is arranged in a 'T' shape. A cushion block 18 is slidably arranged inside the second slide rail 17, and a clamping groove 19 is opened in the middle of the cushion block 18. When clamping the lens, first pull the handle 13 outwards to make the latch 14 away from the rack bar 11, so that the sliding rod 9 can be quickly moved to a suitable position, and under the action of the elastic element 12, the rack bar 11 is engaged with the latch 14, so that the sliding rod 9 can be temporarily fixed. When tightening the lens, directly push the sliding rod 9 inwards, which can further improve the working efficiency and speed up the working process; the third spring 16 in the mounting bracket 15 can prevent the lens from being damaged due to over-tightening when tightening the lens, and the cushion block 18 that can be replaced in the second slide rail 17 according to different specifications of the lens can further protect the lens.

[0027] Furthermore, the clamping groove 19 can clamp the edge of the lens to prevent the lens from loosening or sliding during the processing of the lens.

[0028] Working principle: When using the clamping device for anti-fog spectacle lens coating, first, when coating the lens, push the push rod 4 inward to move the friction block 3 away from the first slide rail 2. In this way, the mounting ring 1 can rotate inside the bracket 5 and can also rotate around the center of the push rod 4, so that the mounting ring 1 can rotate flexibly during coating. Secondly, when clamping the lens, first pull the handle 13 outward to move the pin 14 away from the rack 11. In this way, the slide rod 9 can be quickly moved to the appropriate position, and under the action of the elastic element 12, the rack 11 meshes with the pin 14, and the slide rod 9 can be temporarily fixed. When fastening the lens, directly push the slide rod 9 inward, which can further improve the work efficiency and speed up the work process. Finally, the spring three 16 in the mounting frame 15 can prevent damage to the lens caused by over-tightening when fastening the lens, and the cushion block 18 installed in the second slide rail 17 can be replaced according to different specifications of the lens, so as to further protect the lens. This is the working principle of the clamping device for anti-fog spectacle lens coating.
