Abstract
Description
Technical Field
[0001] This utility model relates to the field of lens manufacturing technology, and in particular to a film-applying device for the production of multifocal progressive lenses. Background Technology
[0002] Multifocal progressive lenses are a special type of eyeglass lens that has multiple different focal zones on the same lens to meet the visual needs of different distances. The refractive power gradually changes from top to bottom. The upper zone is used for distance vision and provides clear long-distance vision. The middle part is a transition zone with a smooth change in refractive power, which can be used for viewing intermediate objects. The lower zone is mainly used for near vision. This type of lens avoids the obvious dividing line between different focal points in traditional multifocal lenses, making the visual transition more natural and smooth. It can reduce the accommodation burden on the eyes when viewing objects at different distances and provide a more comfortable visual experience.
[0003] In existing technologies, when applying film to lenses, the film is usually placed directly on top of the lens and then cut. This may cause damage to the film during cutting because it is not fixed, resulting in an incomplete film on the lens, reducing the yield rate of lens film application, and increasing material waste and labor costs in the production process. Summary of the Invention
[0004] The problem to be solved by this utility model is to propose an improvement or replacement solution to address the shortcomings of the prior art, and in particular, to provide a film-applying device for the production of multifocal progressive lenses.
[0005] To solve the above problems, the present invention adopts the following solution: a film-applying device for producing multifocal progressive lenses, comprising a film-applying mechanism, a feeding mechanism, and a film-laying mechanism, wherein the feeding mechanism is located inside the film-applying mechanism, and the film-laying mechanism is located in front of the film-applying mechanism;
[0006] The film-applying mechanism includes a housing, an electric rotating disk inside the housing, a protective plate fixedly connected to the outer wall of the housing, a groove formed on the inner wall of the protective plate, a fixed plate slidably connected to the outer wall of the groove, a support plate fixedly connected to the top of the fixed plate, a motor fixedly connected to the bottom of the support plate, a cutting blade fixedly connected to the output end of the motor, a first support plate fixedly connected to the top of the fixed plate, a cylinder fixedly connected to the top of the first support plate, a sliding rod slidably connected inside the fixed plate, a limit post fixedly connected to the outer wall of the sliding rod, a pressure plate fixedly connected to the end of the sliding rod away from the limit post, and a spring slidably connected to the outer wall of the sliding rod.
[0007] As a further improvement to the above solution, the cylinder is fixedly connected to the top of the inner wall of the protective plate, and the limiting post is contacted and set on the top of the fixed plate.
[0008] Through the above technical solution, the cylinder drives the support plate to move, while the support plate is fixed to the fixed plate, allowing the fixed plate to slide on the outer wall of the groove. A sliding rod slides inside the fixed plate, and a spring slides on the outer wall of the sliding rod. The sliding rod is fixed to the limiting post and the pressure plate. When the fixed plate descends, the pressure plate first contacts the film. As the fixed plate continues to descend, it compresses the spring, which transmits pressure to the pressure plate, thus pressing and fixing the film. The support plate is fixed to the top of the fixed plate, and the motor drives the cutting blade to rotate, thereby cutting the film. This completes the lens film application. The pressure plate ensures that the film does not move during the cutting process, improving the film application accuracy, ensuring the integrity of the film on the lens, reducing the defect rate, and reducing production costs.
[0009] As a further improvement to the above solution, the feeding mechanism includes a slide groove, which is formed on the inner wall of the housing. As a further improvement to the above solution, a connecting plate is slidably connected to the outer wall of the slide groove, and a motor is fixedly connected to the top of the connecting plate.
[0010] As a further improvement to the above solution, a placement plate is fixedly connected to the output end of the motor, and a cylinder is fixedly connected to the end of the connection plate away from the motor. The cylinder is fixedly connected to the bottom of the inner wall of the housing.
[0011] With the above technical solution, after the lens is transported to the top of the placement plate, the motor drives the placement plate to rotate, so that the placement plate rotates around the motor. A connecting plate is fixed at the bottom of the motor, and the cylinder pushes the connecting plate to slide along the outer wall of the slide groove, thereby lifting the lens to the position of the electric rotating disk for easy film application. Automatic feeding reduces human interference, lowers labor costs, and improves work efficiency.
[0012] As a further improvement to the above solution, the film feeding mechanism includes an electric film feeding wheel, which is fixedly connected to the outer wall of the housing, and a feeding wheel is fixedly connected to the outer wall of the housing.
[0013] As a further improvement to the above solution, an auxiliary wheel is fixedly connected to the outer wall of the housing, and an electric feeding wheel is fixedly connected to the outer wall of the housing.
[0014] With the above technical solution, when the lens reaches the position of the electric rotating disk, the film is placed at the position of the feeding wheel. At this time, the film is attached to the surface of the electric rotating disk through the auxiliary wheel. At the same time, the electric feeding wheel rolls up the cut waste film, which is convenient for unified collection.
[0015] The technical effects of this utility model are as follows: This utility model uses a cylinder to drive a support plate to move, while the support plate is fixed to a fixed plate, allowing the fixed plate to slide on the outer wall of the groove. A sliding rod slides inside the fixed plate, and a spring slides on the outer wall of the sliding rod. The sliding rod is fixed to a limiting post and a pressure plate. When the fixed plate descends, the pressure plate first contacts the film. As the fixed plate continues to descend, it compresses the spring, which transmits pressure to the pressure plate, thus pressing and fixing the film. The support plate is fixed to the top of the fixed plate, and the motor drives the cutting blade to rotate, thereby cutting the film. This completes the lens film application. The pressure plate ensures that the film does not move during the cutting process, improving the film application accuracy, ensuring the integrity of the film on the lens, reducing the defect rate, and reducing production costs.
[0016] This invention utilizes a motor to rotate the placement plate after the lens is transported to the top of the placement plate. The placement plate rotates around the motor, and a connecting plate is fixed at the bottom of the motor. A cylinder pushes the connecting plate to slide along the outer wall of the slide groove, thereby lifting the lens to the position of the electric rotating disk for easy film application. The automatic feeding reduces human interference, lowers labor costs, and improves work efficiency. Attached Figure Description

The feeding mechanism 2 is located inside the film-applying mechanism 1, and the film-laying mechanism 3 is located on the front of the film-applying mechanism 1.
[0025] The film application mechanism 1 includes a housing 101, an electric rotating disk 102 inside the housing 101, a protective plate 103 fixedly connected to the outer wall of the housing 101, a sliding groove 104 on the inner wall of the protective plate 103, a fixed plate 105 slidably connected to the outer wall of the sliding groove 104, a support plate 106 fixedly connected to the top of the fixed plate 105, a motor 107 fixedly connected to the bottom of the support plate 106, a cutting blade 108 fixedly connected to the output end of the motor 107, a support plate 109 fixedly connected to the top of the fixed plate 105, a cylinder 110 fixedly connected to the top of the support plate 109, a sliding rod 111 slidably connected inside the fixed plate 105, a limit post 112 fixedly connected to the outer wall of the sliding rod 111, a pressure plate 113 fixedly connected to the end of the sliding rod 111 away from the limit post 112, and a spring 114 slidably connected to the outer wall of the sliding rod 111.
[0026] The cylinder 110 is fixedly connected to the top of the inner wall of the protective plate 103, and the limiting post 112 is contacted and set at the top of the fixed plate 105.
[0027] The feeding mechanism 2 includes a chute 201, which is formed on the inner wall of the housing 101.
[0028] A connecting plate 202 is slidably connected to the outer wall of the slide 201, and a motor 203 is fixedly connected to the top of the connecting plate 202.
[0029] A placement plate 204 is fixedly connected to the output end of motor 203. A cylinder 205 is fixedly connected to the end of the connecting plate 202 away from motor 203. The cylinder 205 is fixedly connected to the bottom of the inner wall of housing 101.
[0030] The film feeding mechanism 3 includes an electric film feeding wheel 301, which is fixedly connected to the outer wall of the housing 101. A feeding wheel 302 is fixedly connected to the outer wall of the housing 101.
[0031] An auxiliary wheel 303 is fixedly connected to the outer wall of the housing 101, and an electric feeding wheel 304 is fixedly connected to the outer wall of the housing 101.
[0032] The implementation principle of the film-applying device for multifocal progressive lens production in this embodiment is as follows: When the lens is transported to the top of the placement plate 204, the motor 203 drives the placement plate 204 to rotate, causing the placement plate 204 to rotate around the motor 203. A connecting plate 202 is fixed at the bottom of the motor 203. The cylinder 205 pushes the connecting plate 202 to slide along the outer wall of the slide groove 201, thereby lifting the lens to the position of the electric rotating disk 102 for easy film application. Automatic feeding reduces human interference, lowers labor costs, and improves work efficiency. When the lens reaches the position of the electric rotating disk 102, the film is placed at the position of the feeding wheel 302. At this time, the film adheres to the surface of the electric rotating disk 102 through the auxiliary wheel 303. At the same time, the electric feeding wheel 304 winds up the cut waste film for easy collection. The electric film feeding wheel 301 also winds up the protective film. The cylinder 110 drives... The support plate 109 moves while being fixed to the fixed plate 105, allowing the fixed plate 105 to slide on the outer wall of the slide groove 104. A sliding rod 111 slides inside the fixed plate 105, and a spring 114 slides on the outer wall of the sliding rod 111. Simultaneously, the sliding rod 111 is fixed to the limiting post 112 and the pressure plate 113. When the fixed plate 105 descends, the pressure plate 113 first contacts the film. As the fixed plate 105 continues to descend, it compresses the spring 114, which transmits pressure to the pressure plate 113, thus pressing and fixing the film. A fixed plate 16 is placed at the top of the fixed plate 105, and the support plate 106 is fixed to the motor 107. The motor 107 then drives the cutting blade 108 to rotate, cutting the film. This completes the lens film application. The pressure plate 113 ensures that the film does not move during the cutting process, improving application accuracy, ensuring the integrity of the film on the lens, reducing the defect rate, and lowering production costs.
