Technical Field

[0001] This utility model belongs to the field of lens manufacturing technology, and specifically relates to a positioning device for optical lens manufacturing. Background Technology

[0002] Optical lenses are made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula, melting them at high temperature in a platinum crucible, stirring them evenly with ultrasound to remove air bubbles, and then slowly cooling them for a long time to prevent internal stress from forming in the glass block. After cooling, the glass block must be inspected by optical instruments to ensure that its appearance meets specifications.

[0003] In optical lens manufacturing, positioning devices are often required to position the optical lenses. However, existing positioning devices can only clamp the optical lenses and do not have the function of adjusting the orientation of the optical lenses. Furthermore, during the appearance inspection of optical lenses, multiple surfaces of the optical lens need to be inspected separately. Therefore, this application proposes a positioning device for optical lens manufacturing that can adjust the orientation of the optical lenses. Utility Model Content

[0027] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0028] like Figures 1-5 As shown in the figure, an embodiment of this utility model provides a positioning device for optical lens production, including clamping heads and a positioning platform 10. Two clamping heads are provided, located on the upper and lower sides of the lens 2 respectively. The two clamping heads, located on the upper and lower sides of the lens 2 respectively, are capable of clamping or releasing the lens 2.

[0029] Specifically, the clamping head includes clamping blocks 1 and soft pads 3. Two clamping blocks 1 are provided, symmetrically distributed. One clamping block 1 has an arc-shaped portion on the side near the lens 2, which mates with the outer wall of the lens 2. The soft pad 3 is installed at the position of the arc-shaped portion and is bonded to the clamping block 1 with adhesive. The size of the clamping block 1 is larger than the thickness of the lens 2. The length of the clamping block 1 is greater than the thickness of the lens 2, and the soft pad 3 is installed on the side of the clamping block 1 near the lens 2. This ensures that when the clamping block 1 clamps the lens 2, it can completely press down the lens 2 at the contact area between the clamping block 1 and the lens 2. The contact area between the clamping block 1 and the lens 2 is large, resulting in a more stable clamped lens 2. Furthermore, the soft pad 3 provides cushioning when the clamping block 1 presses against the lens 2, preventing damage to the edges of the lens 2 from the pressure of the clamping block 1. The lens 2, as a lens element of the camera, is a type of optical lens.

[0030] More specifically, a support frame 4 is provided on the side of the clamping block 1 away from the lens 2. The support frame 4 includes two vertical rods, which are respectively connected to the two clamping blocks 1.

[0031] It also includes a square tube 8, one end of which is provided with a movable part 5, and the square tube 8 is movably connected to the clamping head through the movable part 5.

[0032] To facilitate the adjustment of the orientation of lens 2 and thus the inspection of its appearance, a direction adjustment rod 6 and an adjustment motor 7 are provided on the positioning stage 10. The direction adjustment rod 6 has a square part, and a square groove is provided inside the clamping head. The square part and the square groove are inserted into each other. The length of the square part is greater than the maximum stroke of the clamping head. The square part and the square groove can only move up and down relative to each other. The clamping head moves up and down to clamp and release lens 2. During this process, the square groove in the clamping head always cooperates with the square part. The output end of the adjustment motor 7 cooperates with the direction adjustment rod 6. The adjustment motor 7 is set on the positioning stage 10. When the adjustment motor 7 is started, the direction adjustment rod 6 rotates, which in turn drives the clamping head and lens 2 to rotate, changing the orientation of lens 2. This allows lens 2 to face the inspection device at multiple angles, enabling the inspection of the appearance of lens 2 from multiple angles.

[0033] In order to clamp and release the lens 2, a clamping drive mechanism 9 is provided on the positioning stage 10. The clamping drive mechanism 9 is connected to the clamping head. The clamping drive mechanism 9 is used to drive the two clamping heads to move closer to each other to clamp the lens 2, and to drive the two clamping heads to move away from each other to release the lens 2.

[0034] Specifically, the clamping drive mechanism 9 includes a circular plate 901, an inclined plate 902, a lifting plate 903, a pressure plate 904, a spring 905, a lifting joint 906, and a drive motor 907. A power shaft is inserted at the center of the circular plate 901, and the power shaft is connected to the output end of the drive motor 907 through a coupling. Two first connecting rods are inserted at the non-center position of the circular plate 901, and the line connecting the centers of the two first connecting rods coincides with the center of the circular plate 901. The first connecting rods are movably connected to the inclined plate 902, and the other end of the inclined plate 902 is movably connected to the lifting plate 903. The lifting plate 903 is connected to the pressure plate 904, and the pressure plate 904 is sleeved on the outside of the square tube 8, and the pressure plate 904 and the square tube 8 can slide up and down relative to each other.

[0035] More specifically, a spring 905 is fitted on the outside of the square tube 8. One end of the spring 905 is connected to the pressure plate 904, and the other end of the spring 905 is connected to the lifting joint 906. The lifting joint 906 is fitted on the square tube 8. A guide tube is provided on the positioning platform 10. The square tube 8 is inserted into the guide tube, and the square tube 8 and the guide tube can only slide relative to each other up and down.

[0036] The drive motor 907 can drive the circular plate 901 to rotate in both directions. The rotation angle of the circular plate 901 generally does not exceed 90°. When the circular plate 901 rotates in both directions, it can drive the lifting plate 903 and the pressure plate 904 to move up and down through the inclined plate 902. The pressure plate 904 drives the lifting joint 906 and the square tube 8 to move up and down through the spring 905, which can adjust the height of the clamping head and clamp or release the lens 2.

[0037] In summary, this utility model embodiment provides a positioning device for optical lens production. The clamping drive mechanism 9, when activated, drives two clamping heads to move closer or further apart, thereby clamping or releasing the lens 2. A movable part 5 is provided between the clamping head and the square tube 8. One of the movable parts 5 is equipped with an adjusting motor 7 and a direction adjusting rod 6. The direction adjusting rod 6 has a square portion, and the clamping head has a square groove. The square portion and the square groove are inserted into each other. The length of the square portion is greater than the maximum stroke of the clamping head. The square portion and the square groove can only move vertically relative to each other. The clamping head moves vertically to clamp and release the lens 2. During this process, the square groove in the clamping head always engages with the square portion. Activating the adjusting motor 7 rotates the direction adjusting rod 6, thereby rotating the clamping head and the lens 2, changing the orientation of the lens 2. This allows the lens 2 to face the detection device at multiple angles, enabling the lens 2 to undergo shape detection from multiple angles.

[0038] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
