[0001] This utility model belongs to the field of lens processing technology and relates to a positioning device for processing sunglasses lenses. Background Technology

[0002] 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 eyeglass frames to form eyeglasses, used to correct the user's vision and obtain a clear field of vision. In an era of continuous technological advancement, lenses can provide a wide field of vision to meet customer needs. Good visual design can improve the realism of vision, relieve eye fatigue, and improve the consumer's wearing experience. During the processing of lenses, cutting, grinding, or polishing are required. Before the above processing is carried out, the lenses need to be clamped and fixed.

[0003] The following technical problems were found in the existing technology: the existing lens clamping equipment cannot flip the lens after clamping it. When both sides of the lens need to be processed, the operator needs to remove the lens, flip it, and then clamp it again, which is inconvenient and affects the processing efficiency of the lens. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing lens clamping devices cannot flip the lens after clamping it. When both sides of the lens need to be processed, the operator must first remove the lens, flip it, and then clamp it again, which is inconvenient and affects the processing efficiency of the lens.

[0005] The present invention discloses a sunglasses lens processing and positioning device, comprising a fixed base, with support frames fixed at both ends of the top of the fixed base, and a connecting frame disposed at the middle position of the two support frames. A rotating shaft and a limiting shaft are respectively fixed at both ends of the connecting frame, and the connecting frame is rotatably connected to the support frames via the rotating shaft and the limiting shaft. A limiting component is disposed on the inner side of the support frame at a position corresponding to the limiting shaft. A rotating handle is fixed at the end of the rotating shaft away from the connecting frame. A clamping component is disposed on the inner side of the connecting frame for clamping and fixing the lens. A placement component is disposed at the top middle position of the fixed base.

[0006] The clamping assembly includes multiple fixing frames, which are evenly arranged inside the connecting frame. An electric push rod is provided between the fixing frame and the connecting frame. The fixed end of the electric push rod is fixedly connected to the connecting frame, and the telescopic end of the electric push rod is fixedly connected to the fixing frame. An abutment block is provided inside the fixing frame. Two second sliding rods are symmetrically fixed at both ends of the abutment block near the fixing frame. The end of the second sliding rod away from the abutment block extends to the outside of the fixing frame. The second sliding rod is slidably connected to the fixing frame. A second fixing plate is fixed to the end of the second sliding rod located outside the fixing frame. A second contraction spring is sleeved on the outside of the end of the second sliding rod near the second fixing plate. One end of the second contraction spring is fixedly connected to the second fixing plate, and the other end of the second contraction spring is fixedly connected to the fixing frame.

[0007] The inner side of the fixing frame is symmetrically provided with two clamping wheels. The middle of each clamping wheel is rotatably connected to a first sliding rod. The end of the first sliding rod away from the clamping wheel extends to the outer side of the fixing frame. The end of the first sliding rod away from the clamping wheel is fixed with a first fixing plate. The outer side of the end of the first sliding rod near the first fixing plate is fitted with a first contraction spring. One end of the first contraction spring is fixedly connected to the fixing frame, and the other end of the first contraction spring is fixedly connected to the first fixing plate.

[0008] The placement assembly includes a placement frame, which is located at the lower center of the connecting frame. Two connecting rods are symmetrically arranged on the outer side of the lower end of the placement frame. The connecting rods are rotatably connected to the placement frame. A movable base is rotatably connected to the end of the connecting rod away from the placement frame. The movable base is slidably connected to a fixed base. An adjusting screw is rotatably connected to the inner side of the fixed base at a position corresponding to the movable base. A drive motor is fixed to the inner side of one end of the fixed base at a position corresponding to the adjusting screw.

[0012] The coordinated structural design of the placement component and the clamping component allows the lens to be placed in advance before being clamped by the clamping component. When flipping is required, the placement component is lowered to avoid affecting the flipping of the connecting frame, thus effectively improving the practicality of the device.

[0020] Example 1 like Figures 1-4 As shown, the device includes a fixed base 1, with support frames 2 fixed at both ends of the top of the fixed base 1. A connecting frame 3 is provided at the middle of the two support frames 2. To facilitate the connection between the connecting frame 3 and the support frame 2, a rotating shaft 19 and a limiting shaft 21 are fixed at both ends of the connecting frame 3, respectively. The connecting frame 3 is rotatably connected to the support frame 2 through the rotating shaft 19 and the limiting shaft 21. A limiting component is provided on the inner side of the support frame 2 at the position corresponding to the limiting shaft 21. To facilitate the rotation of the connecting frame 3, a rotating handle 20 is fixed at the end of the rotating shaft 19 away from the connecting frame 3. A clamping component is provided on the inner side of the connecting frame 3 for clamping and fixing the lens. A placement component is provided at the top middle of the fixed base 1.

[0021] The clamping assembly includes multiple fixed frames 9, which are evenly arranged inside the connecting frame 3. To facilitate the movement of the fixed frames 9, an electric push rod 18 is provided between the fixed frame 9 and the connecting frame 3. The fixed end of the electric push rod 18 is fixedly connected to the connecting frame 3, and the telescopic end of the electric push rod 18 is fixedly connected to the fixed frame 9. An abutment block 10 is provided inside the fixed frame 9. To facilitate the support of the abutment block 10, two second sliding rods 15 are symmetrically fixed at both ends on the side of the abutment block 10 near the fixed frame 9. The end of the second sliding rod 15 away from the abutment block 10 extends to the outside of the fixed frame 9 and is slidably connected to the fixed frame 9. A second fixed plate 16 is fixed to the end of the second sliding rod 15 located on the outside of the fixed frame 9. To facilitate the limiting of the abutment block 10 by the second sliding rod 15, a second fixed plate 16 is sleeved on the outside of the end of the second sliding rod 15 near the second fixed plate 16. A second contraction spring 17 is provided, with one end of the second contraction spring 17 fixedly connected to the second fixed plate 16 and the other end of the second contraction spring 17 fixedly connected to the fixed frame 9. To facilitate clamping and limiting the lens, two clamping wheels 11 are symmetrically arranged on the inner side of the fixed frame 9. Both the clamping wheels 11 and the contact block 10 are made of rubber to avoid damaging the lens. The middle of each clamping wheel 11 is rotatably connected to a first sliding rod 12. The end of the first sliding rod 12 away from the clamping wheel 11 extends to the outside of the fixed frame 9. The end of the first sliding rod 12 away from the clamping wheel 11 is fixedly connected to a first fixed plate 14. To facilitate limiting the clamping wheel 11 through the first sliding rod 12, a first contraction spring 13 is sleeved on the outer side of the end of the first sliding rod 12 near the first fixed plate 14. One end of the first contraction spring 13 is fixedly connected to the fixed frame 9 and the other end of the first contraction spring 13 is fixedly connected to the first fixed plate 14. The limiting assembly includes a limiting plate 24, which is fixed to the end of the limiting shaft 21 away from the connecting frame 3. The limiting plate 24 is rotatably connected to the support frame 2. A movable rod 22 is slidably connected to the inner side of the support frame 2 at a position corresponding to the limiting plate 24. To facilitate limiting the rotation of the limiting shaft 21 and the connecting frame 3 via the limiting plate 24, a movable plate 25 is fixed to the end of the movable rod 22 near the limiting plate 24. Multiple limiting bolts 26 are evenly fixed to the side of the movable plate 25 near the limiting plate 24. Limiting holes 28 are provided at the positions corresponding to the limiting bolts 26 on the positioning plate 24. The limiting bolts 26 are inserted into the limiting plate 24 through the limiting holes 28. In order to facilitate the movement of the moving rod 22, a lifting handle 23 is fixed at the other end of the moving rod 22. In order to facilitate the limiting of the moving plate 25, a limiting spring 27 is sleeved on the outer side of the end of the moving rod 22 near the moving plate 25. One end of the limiting spring 27 is fixedly connected to the moving plate 25, and the other end of the limiting spring 27 is fixedly connected to the support frame 2.

[0022] During operation, the lens is first placed on the placement assembly. Then, by activating the electric push rod 18, the electric push rod 18 moves the fixing frame 9 towards the lens. When the fixing frame 9 moves to the point where the lens contacts the clamping wheel 11, the lens will squeeze the clamping wheel 11, causing the clamping wheel 11 to move towards the first sliding rod 12. When the first sliding rod 12 moves, it will stretch the first contraction spring 13 through the first fixing plate 14. At the same time, when the lens contacts the abutment block 10, it will drive the second sliding rod 15 and the second fixing plate 16 to move simultaneously through the abutment block 10, and will stretch the second contraction spring 17. The fixing frame 9 is moved to the point where the abutment block 10 contacts the fixing frame. When the inner side of 9 contacts, the electric push rod 18 stops. At this time, under the elastic action of the first contraction spring 13, the clamping wheel 11 is driven to move closer to the lens through the first fixed plate 14 and the first sliding rod 12. Then, the lens is clamped and fixed by the cooperation of the clamping wheel 11 and the abutment block 10. Then, the placement component is stored. When it is necessary to flip the lens, firstly, the rotation limit of the connecting frame 3 by the limiting component is released. Then, by rotating the rotating handle 20, the rotating handle 20 drives the connecting frame 3 to rotate through the limiting shaft 21, thereby flipping the lens. After flipping, the rotation of the connecting frame 3 is limited by the limiting component, thereby completing the flipping work.

[0023] Example 2 like Figures 1-3As shown, the placement assembly includes a placement frame 4, which is located at the lower center of the connecting frame 3. To facilitate the support and connection of the placement frame 4, two connecting rods 5 are symmetrically arranged on the outer side of the lower end of the placement frame 4. The connecting rods 5 are rotatably connected to the placement frame 4. To facilitate the rotation of one end of the connecting rod 5, a movable base 6 is rotatably connected to the end of the connecting rod 5 away from the placement frame 4. The movable base 6 is slidably connected to the fixed base 1. To facilitate the movement of the movable base 6, an adjusting screw 7 is rotatably connected to the inner side of the fixed base 1 at a position corresponding to the movable base 6. To facilitate the rotation of the adjusting screw 7, a drive motor 8 is fixedly fixed to the inner side of one end of the fixed base 1 at a position corresponding to the adjusting screw 7. The output end of the drive motor 8 is fixedly connected to the adjusting screw 7.

[0024] When it is necessary to clamp and place the lens, first start the drive motor 8, which drives the adjusting screw 7 to rotate. When the adjusting screw 7 rotates, it will drive the moving base 6 to move along the axis of the adjusting screw 7. When the moving base 6 moves, it will drive the end of the connecting rod 5 to move closer to each other, so that the connecting rod 5 drives the placement frame 4 to rise. Then the lens can be placed on the top of the placement frame 4. When it is necessary to flip it after clamping, start the drive motor 8 to rotate in the opposite direction, so that the placement frame 4 will fall down to avoid affecting the rotation of the connecting frame 3.

[0025] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
