Description

Technical Field

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

[0002] Optical lenses are an important component in the field of optics. They can refract, focus, or diverge light, thereby enabling precise control and adjustment of light. In the manufacturing process of optical lenses, the polishing process is a key step.

[0003] Currently, when using a grinding device to grind optical lenses, it is necessary to limit the optical lens. However, when limiting the optical lens, it is not conducive to aligning the optical lens with its size and fixing it in the center position. This results in uneven grinding force on the sides of the optical lens during full grinding due to the positional deviation of the limiter, leading to defects. Furthermore, the operation of picking up and putting down the optical lens is inconvenient. Therefore, we propose an external grinding device for optical lenses to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide an external polishing device for optical lenses, in order to solve the problems mentioned in the background art, such as the inconvenience of fixing the optical lens in the middle position due to the size of the optical lens, and the inconvenience of picking up and putting down the optical lens.

[0008] Preferably, the mounting cover and the mounting plate form a rotating structure, and a hydraulic rod three distributed at an inclined angle is provided between the mounting cover and the mounting plate.

[0009] Preferably, the fixing plate has an arc-shaped structure, and the fixing plate is distributed at equal angles about the longitudinal center line of the placement seat.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 The present invention provides the following technical solution: an external polishing device for an optical lens, including a worktable 1, a support frame 2 installed above the worktable 1, a hydraulic rod 3 installed above the support frame 2, a mounting base 4 connected to the output end of the hydraulic rod 3, a hydraulic rod 5 installed on the mounting base 4, a mounting plate 6 connected to the output end of the hydraulic rod 5, a mounting cover 7 hinged below the mounting plate 6, a motor 8 installed inside the mounting cover 7, a polishing roller 9 connected to the output end of the motor 8, and a hydraulic rod 10 hinged to the end of the mounting plate 6, the output end of the hydraulic rod 10 being hinged to the mounting cover 7;

[0025] Furthermore, the mounting cover 7 and the mounting plate 6 form a rotating structure. A hydraulic rod 10 is provided between the mounting cover 7 and the mounting plate 6 in an inclined manner, which can adjust the angle of the mounting cover 7, thereby adjusting the angle of the grinding roller 9 and adjusting the grinding tilt of the optical lens.

[0026] A motor 11 is installed on the lower side of the workbench 1. The output end of the motor 11 is connected to a placement seat 12. A spring 13 is connected to the upper side of the placement seat 12. A fixing plate 14 is connected to the end of the spring 13. A moving rod 15 is connected to the middle of the fixing plate 14. A magnet 16 is installed at the end of the moving rod 15 away from the fixing plate 14. A positioning hole 17 is opened on the lower side of the moving rod 15.

[0027] Furthermore, the fixing plate 14 has an arc-shaped structure, and the fixing plate 14 is distributed at equal angles about the longitudinal center line of the placement seat 12. The fixing plate 14 is used to adjust and fix the position of the optical lens, and fix the optical lens at the center position of the placement seat 12.

[0028] The placement base 12 is equipped with an adjustment component that enables convenient placement and removal of the optical lens;

[0029] Furthermore, the adjustment assembly includes a fixed ring 18 installed at the lower end of the placement seat 12, a second spring 19 connected inside the fixed ring 18, a moving ring 20 connected to the upper end of the second spring 19, a limit ring 21 provided on the inner wall of the moving ring 20, an adjustment ring 22 connected inside the limit ring 21, a protruding plate 23 and a positioning rod 25 installed above the adjustment ring 22, and a second magnet 24 installed on the inner wall of the protruding plate 23.

[0030] Furthermore, the lower end of the moving rod 15 is provided with positioning holes 17 at equal intervals. The positioning holes 17 engage with the positioning rod 25, which moves to the corresponding position as the adjusting ring 22 rotates. The positioning rod 25 and the protruding plate 23 are alternately distributed on the adjusting ring 22. The moving rod 15 is fixed by the engagement of the positioning rod 25 and the positioning hole 17, thereby fixing the fixing plate 14 and stabilizing the limiting of the optical lens by the fixing plate 14.

[0031] Furthermore, the adjusting ring 22 forms a rotating structure with the moving ring 20 through the limiting ring 21. The adjusting ring 22 slides through the fixed ring 18, which can flexibly adjust the position of the magnet 24 and the positioning rod 25, thereby realizing the position adjustment and limiting of the fixed plate 14.

[0032] Specifically, the optical lens is placed on the placement base 12, and the adjusting ring 22 is pressed down, causing the moving ring 20 to move downward under force. The moving ring 20 presses and stores the force of the second spring 19, causing the second magnet 24 to move downward, thus misaligning the positions of the first magnet 16 and the second magnet 24. At this time, the attraction between the oppositely polarized magnets 16 and 24 is released, and the spring 13 in the stored state can push the fixing plate 14 to move towards the center position of the placement base 12. The fixing plate 14 calibrates the optical lens to the center position and fixes it. Then, the adjusting ring 22 is rotated, causing the positioning rod 25 to move below the moving rod 15. The pressure on the adjusting ring 22 is released, and the second spring 19 can control the moving ring 20 to move upward and reset, thereby controlling the adjusting ring 22 to move upward and reset, and locking the positioning rod 25 into the corresponding position. Lock the moving rod 15 in the positioning hole 17 to stabilize the position of the fixing plate 14 and securely fix the optical lens. Open the hydraulic rod 3 to push the mounting base 4 to the left, thereby adjusting the horizontal position of the grinding roller 9. Open the hydraulic rod 5 to push the mounting plate 6 down and adjust the vertical position of the grinding roller 9 so that the grinding roller 9 contacts the edge of the optical lens. Turn on the motor 8 to control the rotation of the grinding roller 9 and grind the optical lens. Open the hydraulic rod 10 to push the mounting cover 7 so that the mounting cover 7 rotates on the mounting plate 6 and the angle of the grinding roller 9 can be adjusted to adjust the grinding angle of the optical lens. Turn on the power of the motor 11 to control the rotation of the placement base 12 connected to the output end, thereby controlling the rotation of the fixed optical lens and grinding the optical lens thoroughly.

[0033] After polishing, press down on the adjusting ring 22, causing the moving ring 20 to move downwards under force. The moving ring 20 presses and stores force on the second spring 19, moving the positioning rod 25 out of the positioning hole 17, releasing the fixation on the moving rod 15. Rotate the adjusting ring 22, causing the second magnet 24 to move to a position below the moving rod 15. Release the pressure on the adjusting ring 22, and the second spring 19 controls the moving ring 20 to move upwards and reset, thereby controlling the adjusting ring 22 to move upwards and reset. The second magnet 24 corresponds to the first magnet 16, and the magnets with opposite poles attract each other, driving the moving rod 15 to move the fixing plate 14 away from the center of the placement seat 12. The fixing plate 14 presses and stores force on the first spring 13, releasing the fixation of the fixing plate 14 on the optical lens, so that the optical lens can be taken out.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
