[0001] The utility model relates to the technical field of optical lens feeding, in particular to an automatic feeding device for optical lens edge grinding. Background Art

[0002] With the rapid development of science and technology, the manufacturing technology of optical lenses has been continuously improved. Modern optical lenses can not only be used for vision correction, but also are widely used in fields such as photography, microscopes, telescopes, lasers, etc. For example, high-quality optical lenses are used in modern digital cameras, smartphones and other devices to achieve clear imaging effects. Optical lenses play a key role in glasses. By selecting appropriate lens materials, functions and shapes, the vision correction needs of different people can be met.

[0003] Before grinding the lens, first select a suitable optical material according to the performance requirements of the lens, then check the optical lens blank to ensure that its surface has no obvious defects, and then fix the optical lens blank on the grinding equipment to ensure its stable position. After grinding, remove the lens from the grinding equipment and clean it with clean water or a special cleaning agent to remove the polishing materials and impurities on the lens surface. Then use an interferometer to check the surface quality and optical performance of the lens to ensure that the lens meets the design requirements.

[0004] For existing lens grinding equipment, the feeding and placement of lenses mostly adopt the method of manual placement. Manually placing lenses usually takes a certain amount of time for positioning and adjustment, and the operation speed is slow, which will reduce the efficiency of the entire grinding production line and increase the production cycle. When manually placing lenses, it is difficult to ensure that the lenses are accurately placed at the established positions of the grinding equipment every time. Summary of the Utility Model

[0005] In view of the problem that manually placing lenses usually takes a certain amount of time for positioning and adjustment, and the operation speed is slow, which will reduce the efficiency of the entire grinding production line, the present utility model is proposed.

[0006] To solve the above technical problems, the present utility model provides the following technical solution: an automatic feeding device for optical lens edge grinding, comprising: a rectangular bottom plate and a loading tray. The loading tray is rotatably connected to the upper surface of the rectangular bottom plate. A ring is fixedly connected to the arc surface of the loading tray.

[0013] Advantages of the present utility model:

[0014] 1. The device realizes the automation of lens feeding and placement. The device also endows the L-shaped blanking frame with the function of overall rotation, so that after the lens grinding is completed, it is more convenient to take the material, preventing the phenomenon that the L-shaped placement frame jams the ground lens and makes it impossible to take the material. Moreover, the rotation of the L-shaped placement frame is also automatic. Workers only need to perform the work of feeding the L-shaped blanking frame and collecting the ground lens, thus eliminating the time wasted when manually placing the lens.

[0015] 2. The way this device fixes the lens is different from that of an efficient optical lens edging device with the application number: CN202120585651.7.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the drawings in the specification.

[0023] Embodiment 1

[0024] Refer to Figure 1 and 4, which is the first embodiment of the present utility model, provides an automatic feeding device for optical lens edging, including: a rectangular bottom plate 1 and a loading disk 2. The loading disk 2 is rotatably connected to the upper surface of the rectangular bottom plate 1. A circular ring 3 is fixedly connected to the arc surface of the loading disk 2. An installation block 4 is fixedly arranged on the upper surface teeth of the loading disk 2. An L-shaped blanking frame 5 is temporarily fixed on the inclined surface of the installation block 4. A guide plate 6 is arranged at the cross-section of the lower end of the L-shaped blanking frame 5. Hydraulic telescopic rods 7 are arranged on the vertical surfaces on both sides of the L-shaped blanking frame 5. The telescopic rods of a pair of hydraulic telescopic rods 7 are both connected to a rectangular connecting plate 8. A rectangular baffle is also arranged at the vertical surface of the rectangular connecting plate 8 close to the L-shaped blanking frame 5. The rectangular baffle penetrates through the L-shaped blanking frame 5, and there is a sliding relationship between the L-shaped blanking frame 5 and the rectangular baffle.

[0025] Several guide blocks 9 with the same spacing are arranged on the arc surface of the circular ring 3. A pair of symmetrically arranged temporary fixing plates 10 are also arranged on the inclined surface of the installation block 4. A toothed plate 19 is arranged on one of the L-shaped moving plates 13. The rectangular block on the toothed plate 19 is in a meshing relationship with the guide block 9 on the circular ring 3. Rectangular notches are respectively formed through the vertical surfaces of the L-shaped moving plate 13 and the fixed block 11 far from the toothed plate 19.

[0026] During use, first, the lens to be processed is inserted into the inlet at the upper end of the L-shaped blanking frame 5. At this time, the L-shaped blanking frame 5 is kept parallel to the pair of fixed blocks 11. Because a guide plate 6 is arranged at the cross-section of the lower end of the L-shaped blanking frame 5, hydraulic telescopic rods 7 are arranged on the vertical surfaces on both sides of the L-shaped blanking frame 5. The telescopic rods of a pair of hydraulic telescopic rods 7 are both connected to a rectangular connecting plate 8. A rectangular baffle is also arranged at the vertical surface of the rectangular connecting plate 8 close to the L-shaped blanking frame 5. The rectangular baffle penetrates through the L-shaped blanking frame 5, and there is a sliding relationship between the L-shaped blanking frame 5 and the rectangular baffle. Then, a pair of hydraulic telescopic rods 7 are started, so that the telescopic rods of the pair of hydraulic telescopic rods 7 push the rectangular connecting plate 8 to slide. As the rectangular connecting plate 8 continuously moves away from the L-shaped blanking frame 5, the lens inside the L-shaped blanking frame 5 falls out from the outlet at the lower end of the L-shaped blanking frame 5 because there is no longer any obstruction. Then, the lens will fall into the inner ring of the limit ring 20 through the guide plate 6. At this time, because the first lens has fallen out, the second lens will contact the arc surface of the first lens. Then, the hydraulic telescopic rods 7 are started again, so that the hydraulic telescopic rods 7 retract with the rectangular baffle. At this time, because the position of the rectangular baffle is closer to the cross-section at the lower end of the L-shaped blanking frame 5 than the center point of the second lens, as the hydraulic telescopic rods 7 retract, the second lens will be pressed back into the L-shaped blanking frame 5 by the rectangular baffle.

[0027] Embodiment 2

[0028] Refer to Figure 2 and 3, which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a pair of fixing blocks 11 are further provided on the upper surface of the rectangular bottom plate 1, and a bidirectional threaded rod 12 is rotatably connected to the vertical surfaces of the pair of fixing blocks 11. A pair of L-shaped moving plates 13 are sleeved on the rod body of the bidirectional threaded rod 12. A guide rod is further provided on the opposite vertical surfaces of the pair of fixing blocks 11, and a driving motor 14 is provided on the vertical surface of the L-shaped moving plate 13.

[0029] A connecting plate 15 is provided at the output end of the driving motor 14, and a lens suction cup 16 is provided on the arc surface of the connecting plate 15. An air extraction pump 17 is further provided on the upper surface of the L-shaped moving plate 13. A connecting hose 18 is provided on the air extraction pump 17. One end of the connecting hose 18 communicates with the connecting plate 15, and the other end of the connecting hose 18 is connected to the air extraction pump 17. A toothed plate 19 is further provided on one of the L-shaped moving plates 13. A support plate is provided on the upper surface of the rectangular bottom plate 1, and a limiting ring 20 is fixedly connected to the upper surface of the support plate. A polishing layer 21 is provided on the inner ring of the limiting ring 20.

[0030] During use, first follow the operation steps in Embodiment 1. After placing the lens into the inner ring of the limiting ring 20, first start the driving motor on the bidirectional threaded rod 12. As the driving motor starts, the bidirectional threaded rod 12 will rotate. Since the L-shaped moving plates 13 are sleeved on the rod body of the bidirectional threaded rod 12, as the pair of L-shaped moving plates 13 move relatively, because the output end of the driving motor 14 is provided with a connecting plate 15 and the lens suction cup 16 is provided on the arc surface of the connecting plate 15, when the pair of L-shaped moving plates 13 move relatively, the lens suction cup 16 will first come into contact with the lens. Then the L-shaped moving plate 13 will move a certain distance, so that a part of the air in the lens suction cup 16 is discharged. At this time, the lens suction cup 16 cannot ensure that it completely sucks the lens. Then start the air extraction pump 17 provided on the upper surface of the L-shaped moving plate 13. Since the connecting hose 18 is provided on the air extraction pump 17, one end of the connecting hose 18 communicates with the connecting plate 15 and the other end of the connecting hose 18 is connected to the air extraction pump 17. As the air extraction pump 17 starts, the air inside the space temporarily formed by the lens suction cup 16 and the lens will be pumped away, so that the lens suction cup 16 firmly sucks the lens. Then start the driving motor 14.

[0031] The remaining structures are the same as those in Embodiment 1.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
