Description

Technical Field

[0001] The utility model relates to the technical field of optical spectacle lens processing equipment, in particular to a convex surface film covering device for processing optical spectacle lenses. Background Technique

[0002] Optical spectacle lenses can correct eyesight, eliminate eye fatigue, protect or treat eyes by using lenses, prisms, contact lenses, intraocular lenses, etc. Optical spectacle lenses are the most important part of glasses. When processing lenses, convex surface film covering is required. In the prior art, fixing of the lenses is needed for film covering, but traditional equipment can only fix lenses of a fixed size and cannot be applied to lenses of different diameters, reducing the practicability of the film covering device. At the same time, there is a lack of a good adsorption effect on the lenses.

[0003] For example, a film covering tool for optical lenses disclosed in the authorized patent document with the application number CN201720710994.5 includes a handle and a roller frame fixedly connected to the handle. The handle is formed by connecting at least two sections of handle bodies. The roller frame includes a support plate. Two connecting ears perpendicularly extend from both ends of the support plate, and the extending directions of the two connecting ears are the same. A blind hole is respectively arranged inside each of the two connecting ears, and the depth of the blind hole is not less than 3 mm. A movable rod is movably arranged between the blind holes of the two connecting ears. A roller is fixedly connected to the movable rod, the diameter of the roller is not less than 20 mm, and the roller is made of silicone rubber material. In the utility model, by making the roller with silicone rubber material having a certain elasticity, the roller can complete the one-time film covering of the optical lens, with high film covering efficiency and good film covering effect, improving the qualified product rate; since the handle is formed by connecting at least two sections of handle bodies, the length of the handle can be selected according to the actual size of the optical lens and the use requirements, and the operation is convenient and flexible.

[0004] The above-mentioned patent cannot be applied to lenses of different diameters and lacks a good adsorption effect on the lenses at the same time. Therefore, we need to provide a convex surface film covering device for processing optical spectacle lenses. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-4 , the present invention provides a technical solution: a convex surface film laminating device for processing optical glasses, including:

[0027] A bench 1;

[0028] And a pressing member 2 provided on the top of the bench 1 for film lamination;

[0029] A fixing member 3 installed inside the bench 1 for lens adsorption;

[0030] The fixing member 3 includes a tube body 31 embedded inside the bench 1. The top of the tube body 31 is communicated with an adhesive layer table 32, and an air groove 33 communicated with the tube body 31 is opened inside the adhesive layer table 32;

[0031] Among them, a pushing member 30 for generating negative pressure inside the tube body 31 is installed at the bottom of the bench 1.

[0032] The pushing member 30 includes a frame 301 fixedly installed at the bottom of the bench 1. A first cylinder 302 is embedded inside the frame 301. The top of the first cylinder 302 is fixedly installed with a sliding seat 303. Rubber rings 305 are installed in two annular grooves 304 on the surface of the sliding seat 303, and the outer surfaces of the two rubber rings 305 are attached to the inner wall of the tube body 31;

[0033] In this embodiment, the concave surface of the optical spectacle lens is placed on the glue layer table 32, and the first cylinder 302 is started to drive the sliding seat 303 to slide in the tube body 31. Since sealing rings are installed in the two annular grooves 304 on the surface of the sliding seat 303, the outer surfaces of the two rubber rings 305 are in contact with the inner wall of the tube body 31. As the sliding seat 303 moves, negative pressure is generated in the space at the top of the sliding seat 303 inside the tube body 31, thereby adsorbing the optical spectacle lens. The top of the rubber table is in close contact with the concave surface of the optical spectacle lens, and can adsorb optical spectacle lenses of different specifications. The film is covered on the optical spectacle lens, and both sides of the film are located at the bottom of the two lower pressing plates 66. The two third cylinders 61 are started. The third cylinder 61 pushes the bottom plate 62 downward, drives the sliding rod 63 downward, and the top plate 64 moves downward. The lower pressing plate 66 presses the film, and the spring 65 is compressed to fix both ends of the film. The second cylinder 22 is started to drive the bonding cotton to bond the film to the top of the optical spectacle lens, and the motor 74 is started to drive the threaded rod 72 to rotate. The sliding seat 73 on the surface of the threaded rod 72 drives the cutting knife 75 to cut the film, thereby completing the film covering of the optical spectacle lens.

[0034] A support table 4 for supporting the glue layer table 32 is fixedly installed on the surface of the tube body 31, and most of the surfaces of the two rubber rings 305 are located in the annular grooves 304;

[0035] It should be noted that most of the surfaces of the two rubber rings 305 are located in the annular grooves 304, so as to prevent the rubber rings 305 from easily detaching from the annular grooves 304, and the support table 4 is provided to support the glue layer table 32. The glue layer table 32 is made of rubber and fits better with the concave surface of the optical spectacle lens.

[0037] Specifically, the second cylinder 22 is started to drive the bonding cotton to bond the film to the top of the optical spectacle lens, and the film is assisted to be pressed on the optical spectacle lens.

[0038] In order to be able to blow off the dust on the optical spectacle lens, a fan 5 is provided inside the mounting frame 21, and a fan 5 for removing dust on the lens surface is provided inside the mounting frame 21.

[0039] It further includes a limiting member 6 for assisting in pressing the film. The limiting member 6 includes two third cylinders 61 fixedly installed at the bottom of the table frame 1. Bottom plates 62 are fixedly installed at the lower ends of the two third cylinders 61. A top plate 64 is fixedly installed on the top of the bottom plate 62 through two sliding rods 63. The lower pressing plate 66 is clamped to the bottom of the top plate 64 through two springs 65;

[0040] It should be noted that two third cylinders 61 are started. The third cylinders 61 push the bottom plate 62 downward, drive the sliding rod 63 downward, the top plate 64 downward, and the lower pressing plate 66 presses the film, and the spring 65 is compressed to fix both ends of the film, thus facilitating the subsequent cutting process of the film by the cutting member 7.

[0041] It further includes a cutting member 7. The cutting member 7 includes two grooves 71 formed inside the bench 1. Inside both of the two grooves 71, a threaded rod 72 is rotatably installed. On the surfaces of both of the two threaded rods 72, a sliding seat 73 with a cutting knife 75 is threadedly installed. One end of the threaded rod 72 is equipped with a motor 74.

[0042] Furthermore, the motor 74 is started to drive the threaded rod 72 to rotate. The sliding seat 73 on the surface of the threaded rod 72 drives the cutting knife 75 to cut the film, thereby completing the film covering of the optical lens.

[0043] The concave surface of the optical lens is placed on the adhesive layer table 32 of this device, and the first cylinder 302 is started to drive the sliding seat 303 to slide within the tube body 31. Since sealing rings are installed in both of the two annular grooves 304 on the surface of the sliding seat 303, the outer surfaces of the two rubber rings 305 are in contact with the inner wall of the tube body 31. As the sliding seat 303 moves, negative pressure is generated in the space above the sliding seat 303 within the tube body 31, thereby adsorbing the optical lens. The top of the rubber table is in close contact with the concave surface of the optical lens, and it can adsorb optical lenses of different specifications. The film is covered on the optical lens, and both sides of the film are located at the bottom of the two lower pressing plates 66. Two third cylinders 61 are started. The third cylinders 61 push the bottom plate 62 downward, drive the sliding rod 63 downward, the top plate 64 downward, the lower pressing plate 66 presses the film, and the spring 65 is compressed to fix both ends of the film. The second cylinder 22 is started to drive the fitting cotton to fit the film on the top of the optical lens, and the motor 74 is started to drive the threaded rod 72 to rotate. The sliding seat 73 on the surface of the threaded rod 72 drives the cutting knife 75 to cut the film, thereby completing the film covering of the optical lens.
