Description

Technical Field

[0001] The utility model relates to the technical field of lens coating, in particular to a device for coating a wear-resistant layer on the surface of a lens. Background Art

[0002] Daily use of eyeglass lenses will cause wear and tear on the lenses. For example, wiping the dust off the lenses with an unclean lens cloth can easily cause scratches on the lens surface. Compared with glass lenses, organic materials have poorer wear resistance and are more prone to scratches. In order to enhance the wear resistance of resin lenses, we add a layer of wear-resistant film between the lens base and the anti-reflection film, commonly known as a hard film, to achieve a wear-resistant effect.

[0003] Among them, an improved optical lens ink coating machine disclosed in application number CN201821847837.X is also an increasingly mature technology. By setting a lens placement device, the degree of depression or protrusion of the elastic connecting membrane can be adjusted, which makes it convenient to place lenses of different sizes on the elastic connecting membrane, thereby facilitating the ink coating of lenses of different sizes. This solves the problem that the lens positioning device on a general optical lens ink coating machine cannot be adjusted according to the shape and size of the lens, and cannot ink lenses of multiple sizes, which will cause certain inconveniences to a certain extent.

[0004] A search of CN202222134331.7 disclosed a lens polishing machine surface wear-resistant layer brushing equipment, which is also an increasingly mature technology. The first drive motor drives the first screw rod to make the moving seat at the bottom of the first screw rod slide down along the first slide rail under the rolling of the moving roller, and then the small motor and the second screw rod cooperate to make the threaded fixing block on one side of the moving seat rotate, and the horizontal fixing frame is adjusted left and right through the thread rotation, so that the rubber coating head is in contact with the wear-resistant layer of the eyeglass product on the brushing turntable for brushing.

[0005] Based on this, we agree with the advantages of the above products, but there are still the following defects:

[0006] Both of these two coating devices can only clamp one lens at a time, and after the coating is completed, the lens cannot be heated and dried, which makes it inconvenient to take the lens, thereby affecting production efficiency. Utility Model Content

[0013] In this solution, the piston end is moved linearly downward through the telescopic rod, and the brushing block is tightly attached to the surface of the lens. The motor drives the main bevel gear to rotate, and then the main bevel gear engages with the transmission slave bevel gear. When the slave bevel gear rotates, it drives the telescopic rod at the bottom to rotate synchronously, which makes it convenient for the suction nozzle to adsorb the lens evenly. The airbag has good deformation performance. When it is squeezed and deformed, it will alarm to prevent the brushing block from damaging the wear-resistant layer on the surface of the lens.

[0014] In one embodiment of the utility model, a limiting ring is integrally connected to the middle of the bottom end of the rotating table, a limiting groove matching with the limiting ring is opened on the top of the working table, and the limiting ring rotates inside the limiting groove.

[0015] In this solution, the limiting ring rotates along the inside of the limiting groove, thereby ensuring accurate rotation of the turntable during operation and preventing the limiting ring from exceeding the limiting groove and causing unnecessary damage.

[0016] In an implementation manner of the utility model, a mounting ring is integrally provided at the top end of the mounting frame, and the interior of the mounting ring is horizontally penetrated through the piston end of the telescopic rod by a shaft rod.

[0017] In this solution, the shaft rod is horizontally passed through the mounting ring, so that when the brush block needs maintenance or replacement, the shaft rod can be directly removed for maintenance or replacement.

[0018] In one embodiment of the utility model, the protective cover is located at the bottom end of the workbench, and ventilation grooves are provided around the protective cover. A pad is provided at the bottom end of the motor, and the pad is located at the top end of the support frame.
