Description

Technical Field

[0001] This utility model relates to the field of optical lens edging technology, specifically an edging device for the production of progressive optical lenses. Background Technology

[0002] Progressive lenses are a special type of eyeglass lens with a unique design and function. The upper half of a progressive lens corrects distance vision, the lower half corrects near vision, and the power gradually changes in the middle transition section. Unlike traditional lenses, they provide continuous refractive power, avoiding the obvious dividing line seen in bifocals.

[0003] The existing Chinese patent announcement number CN218776285U, entitled "An optical lens edging device for production," clearly states in its abstract that "the present invention uses airflow generated by a negative pressure fan to flow from the inside of the guide frame into the collection frame. The guide frame absorbs the debris generated after the optical lens is ground, guiding the debris into the inside of the collection frame. The filter bag collects the debris, preventing the debris generated on the optical lens from causing harm to the human body. Furthermore, by pulling the movable rod upward, the limiting rod moves out of the limiting groove, releasing the fixing of the grinding roller and facilitating the replacement of the grinding roller."

[0004] In this technology, the optical lens needs to be fixed by the fixing blocks on the upper and lower sides. During fixing, the operator needs to place the optical lens on the bottom fixing block. However, it is difficult for the operator to accurately place the middle position of the optical lens at the center of the fixing block. This means that when the fixing block drives the optical lens to rotate, it cannot guarantee that different positions of the optical lens can contact the grinding roller. Therefore, during grinding, it may be necessary to adjust the distance between the grinding roller and the optical lens, thus affecting the grinding efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a grinding device for the production of progressive optical lenses, so as to solve the problem mentioned in the background art that it is difficult for workers to accurately place the middle position of the fixed optical lens at the center of the fixed block.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A grinding device for producing progressive optical lenses includes a mounting frame and three limiting blocks. An annular seat is provided at the bottom inner side of the mounting frame, and a positioning component is provided inside the annular seat.

[0008] The positioning assembly includes a rotating plate, a positioning roller is rotatably mounted on the top of the limiting block, a guide post is mounted on the bottom of the limiting block, and three guide rails are mounted on the rotating plate.

[0009] In a preferred embodiment of the present invention, the rotating plate is rotatably mounted inside the annular seat, a first motor is provided at the bottom inner side of the annular seat, the drive shaft of the first motor is connected to the rotating plate, and the guide column is slidably connected to the guide rail.

[0010] In a preferred embodiment of this utility model, an annular plate is fixedly provided on the top of the annular seat, and three limiting rails are provided on the annular plate. The limiting block is slidably connected to the limiting rails.

[0011] In a preferred embodiment of this utility model, a support platform is rotatably provided above the inner side of the annular plate, and a ball bearing is rotatably provided on the side where the support platform connects to the annular plate.

[0012] In a preferred embodiment of this utility model, a mounting frame is provided on the upper inner side of the mounting frame, an electric telescopic rod is provided on the top of the mounting frame, and the bottom telescopic end of the electric telescopic rod is connected to the mounting frame.

[0013] In a preferred embodiment of the present invention, a second motor is provided at the front of the mounting bracket, and a pressure plate is provided on the bottom drive shaft of the second motor.

[0014] In a preferred embodiment of this utility model, a slide rail is provided at the rear of the mounting bracket, a threaded sliding member is slidably provided inside the slide rail, a third motor is provided inside the threaded sliding member, and a grinding roller is provided on the bottom drive shaft of the third motor.

[0015] In a preferred embodiment of this utility model, a threaded rod is rotatably provided on the top inner side of the slide rail, and the threaded rod is threadedly connected to the threaded sliding member. A fourth motor is provided on the outer side of the slide rail, and the drive shaft of the fourth motor is connected to the threaded rod.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0017] Beneficial effects: By placing the optical lens on the support platform, once the optical lens is in place, the first motor drives the rotating plate, which in turn pushes the guide rail against the guide column and limits the limit block, causing the three positioning rollers to move inward simultaneously. This fixes the optical lens to the center of the support platform, where a pressure plate presses it down. The second motor then drives the pressure plate to rotate, causing the support platform and the optical lens to rotate. The grinding rollers then grind the edges of the optical lens. Because the optical lens is fixed to the center of the support platform, different parts of the optical lens can contact the grinding rollers when the support platform rotates, preventing the grinding rollers from being used indiscriminately during grinding and ensuring grinding efficiency.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] Please refer to Figures 1-5 This utility model discloses a grinding device for producing progressive optical lenses, comprising a mounting frame 1 and three limiting blocks 21. The mounting frame 1 is a mounting structure used to install the overall structure. An annular seat 11 is provided at the bottom inner side of the mounting frame 1. The annular seat 11 is fixedly installed. An annular plate 12 is fixedly provided at the top of the annular seat 11. A support platform 3 is rotatably provided on the upper inner side of the annular plate 12, that is, the optical lens is placed on the support platform 3. The three limiting blocks 21 are mounting structures. Three limiting rails 2 are provided on the annular plate 12. The limiting blocks 21 are slidably connected to the limiting rails 2. The three limiting blocks 21 are equidistantly distributed and the distance between the three limiting blocks 21 and the support platform 3 is equal.

[0028] The annular seat 11 is equipped with a positioning assembly, which includes a rotating plate 13, a positioning roller 22 rotatably mounted on the top of the limiting block 21, a guide post 23 mounted on the bottom of the limiting block 21, and three guide rails 24 mounted on the rotating plate 13. The rotating plate 13 is rotatably mounted inside the annular seat 11. A first motor 14 is mounted on the bottom inner side of the annular seat 11. The drive shaft of the first motor 14 is connected to the rotating plate 13. The guide post 23 is slidably connected to the guide rail 24. After the optical lens is placed, the first motor 14 drives the rotating plate 13, thereby pushing the guide rail 24 against the guide post 23 and limiting the limiting block 21, so that the three positioning rollers 22 move inward at the same time, which can fix the optical lens to the center position of the support platform 3, making installation more convenient.

[0029] The support platform 3 is connected to the annular plate 12 by a rolling ball bearing 31. The support platform 3 and the annular plate 12 do not directly contact each other. The support platform 3 is supported by the ball bearing 31, and the ball bearing 31 rolls, making the rotation of the support platform 3 smoother. The mounting frame 33 is provided on the upper inner side of the mounting frame 1. The mounting frame 33 is a mounting structure. The top of the mounting frame 1 is provided with an electric telescopic rod 32. The bottom telescopic end of the electric telescopic rod 32 is connected to the mounting frame 33. The front of the mounting frame 33 is provided with a second motor 34. The bottom drive shaft of the second motor 34 is provided with a pressure plate 35. The pressure plate 35 and the support platform 3 are both circular and concentric. The electric telescopic rod 32 drives the mounting frame 33 to descend, so that the pressure plate 35 presses on the optical lens. The second motor 34 drives the pressure plate 35 to rotate, so that the support platform 3 and the optical lens rotate.

[0030] A slide rail 4 is located at the rear of the mounting bracket 33. A threaded sliding element 41 is slidably mounted inside the slide rail 4. A third motor 44 is located inside the threaded sliding element 41. A grinding roller 45 is mounted on the bottom drive shaft of the third motor 44. The grinding roller 45 is rotated by the third motor 44 to grind the edge of the optical lens. A threaded rod 42 is rotatably mounted on the top of the inner side of the slide rail 4. The threaded rod 42 is threadedly connected to the threaded sliding element 41. A fourth motor 43 is located on the outer side of the slide rail 4. The drive shaft of the fourth motor 43 is connected to the threaded rod 42. The fourth motor 43 drives the threaded rod 42 to rotate. Through threaded transmission, the threaded sliding element 41 drives the grinding roller 45 at the bottom to grind. The distance between the grinding roller 45 and the optical lens can be adjusted to grind optical lenses of different widths.

[0031] The working principle of this utility model is as follows: The optical lens is placed on the support platform 3. After placement, the first motor 14 drives the rotating plate 13, causing the guide rail 24 to push the guide column 23 and the limiting rail 2 to limit the limiting block 21. This causes the three positioning rollers 22 to move inward simultaneously, thus fixing the optical lens to the center position of the support platform 3, making installation more convenient. The electric telescopic rod 32 drives the mounting frame 33 to descend, causing the pressure plate 35 to press onto the optical lens. The second motor 34 then drives the pressure plate 35 to rotate, thereby... The support platform 3 and the optical lens rotate, and the third motor 44 drives the grinding roller 45 to rotate, thereby grinding the edge of the optical lens. Since the optical lens is fixed to the center of the support platform 3, when the support platform 3 rotates, different positions of the optical lens can contact the grinding roller 45, thus preventing the grinding roller 45 from being pressed during grinding and ensuring grinding efficiency. The fourth motor 43 drives the threaded rod 42 to rotate, and through the threaded transmission, the threaded sliding part 41 drives the grinding roller 45 at the bottom to grind, thereby adjusting the distance between the grinding roller 45 and the optical lens, so as to grind optical lenses of different widths.
