[0002] Spectacle lenses are transparent materials with one or more curved surfaces made of optical materials such as glass or resin. After polishing, they are often assembled with spectacle frames to form glasses. They are used to correct the user's vision and obtain a clear field of vision. Glasses are very important for users with vision problems, so it is also necessary to optimize the processing of spectacle lenses.

[0003] For example, a VR glasses lens film pasting device is disclosed in the Chinese utility model patent with the announcement number CN212331841 U. Although the above-mentioned prior art can realize automatic film pasting of lenses, effectively avoid pollution and damage to the film and lenses during the film pasting process, and can greatly improve the film pasting efficiency compared with manual film pasting, the lenses of the glasses need to be positioned when the film is pasted, and the center point of the film needs to be aligned with the center point of the lens to complete the film pasting. If the positioning is inaccurate, the position of the film will be inconsistent with the optical center of the lens, causing the wearer's line of sight to deviate, affecting the accuracy and comfort of vision. Therefore, it is necessary to design a positioning device for film pasting of glasses. Utility Model Content

[0024] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0025] Please combine Figure 1-Figure 3 A positioning device for applying film to eyeglass lenses in this embodiment includes a film applying base 1, one side of the film applying base 1 is provided with a film applying component 2 for applying film to the eyeglass lens, one side of the film applying component 2 is provided with a moving component 3 for assisting the film applying component 2 to move the film, one side of the film applying base 1 is provided with a plurality of positioning components for pushing the eyeglass lens to position, one side of each positioning component is provided with a control component for controlling the positioning component to reset and push, and one side of one of the control components is provided with a driving component for driving an adjacent control component.

[0026] Combination Figure 1 and Figure 3A plurality of sliding grooves 7 are provided on one side of the film base 1, and the positioning assembly includes a sliding block 401 slidably installed inside the sliding groove 7 and a positioning strip 402 fixedly installed on one side of the sliding block 401. A limiting rod 8 is fixedly installed inside each sliding groove 7, and each limiting rod 8 is slidably matched with an adjacent sliding block 401. A pushing spring 9 is sleeved on each limiting rod 8, and one end of each pushing spring 9 is fixedly installed on the inner wall of the adjacent sliding groove 7 and the other end is fixedly installed on the adjacent sliding block 401. The positioning strip 402 moves with the sliding block 401, so that the lens can be pushed to the positioning point, and the pushing spring 9 will push the sliding block 401.

[0027] Combination Figure 1 and Figure 3 The control component includes a rotating column 501 arranged on one side of the film base 1, a reel 502 fixedly mounted on the rotating column 501, and a pulling wire 503 wound around the reel 502. One end of each rotating column 501 passes through the film base 1, and one end of each pulling wire 503 is fixedly installed on one side of the adjacent positioning strip 402. When the rotating column 501 rotates, the reel 502 will reel in the pulling wire 503, so that the pulling wire 503 drives the positioning strip 402 to move and reset.

[0028] Combination Figure 2 and Figure 3 The driving assembly includes a servo motor 601 arranged on one side of the rotating column 501 and a fixing frame 602 fixedly installed on one side of the servo motor 601. One side of the fixing frame 602 is fixedly installed on the bottom of the film base 1. The output end of the servo motor 601 is fixedly installed on the adjacent rotating column 501. A driving gear 10 is fixedly sleeved on each rotating column 501. A plurality of driving gears 10 are sleeved with a synchronous belt 11 for synchronous transmission. When the servo motor 601 is started, a rotating column 501 will rotate, and the driving gear 10 on the rotating column 501 will drive the synchronous belt 11 to rotate, thereby driving all the driving gears 10 to rotate together, thereby driving all the rotating columns 501.

[0029] The implementation principle of a positioning device for applying film to eyeglass lenses in the embodiment of the present application is as follows: when the eyeglass lenses need to be applied with film, starting the servo motor 601 will cause the adjacent rotating columns 501 to rotate, thereby driving the driving gear 10 above to rotate, so that the synchronous belt 11 will cause all the driving gears 10 to rotate, and all the rotating columns 501 will also rotate. When all the rotating columns 501 rotate, the upper reel 502 will reel in the pulling wire 503, and the reeling of the pulling wire 503 will pull the positioning bar 402 to move, so that the positioning point of the film base 1 will be vacant, and the eyeglass lenses are placed on the positioning point, and the servo motor 601 is started. The servo motor 601 rotates in the opposite direction, so that the winder 502 will also rotate in the opposite direction to loosen the pulling line 503. After the pulling line 503 is loosened, the positioning bar 402 will lose the pulling of the pulling line 503, and the pushing spring 9 will push the sliding block 401, so that the sliding block 401 and the positioning bar 402 can squeeze and push the lens. This setting can not only push the lens accurately to the positioning point, but also adjust the direction of the lens. If the film base 1 is prone to friction with the lens, the film base 1 can be covered with a cloth or film that facilitates the sliding of the lens. It only needs to hollow out the vacant position to facilitate the installation of the device.

[0030] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
