Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing, in particular to a positioning device for optical lens production. Background Art

[0002] Optical lenses are made of a specific mixture of high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., melted at high temperature in a platinum crucible, stirred evenly with ultrasound to remove bubbles, and then cooled slowly over a long period of time to prevent internal stress in the glass block. The cooled glass block must be measured with optical instruments to check whether its purity, transparency, uniformity, refractive index and dispersion meet the specifications.

[0003] In the production of optical lenses, a positioning device is required to position the optical lens. However, in existing positioning devices, such as the assembly positioning device for optical lens production disclosed in patent CN214870406U, manual positioning of the lens is required during the production positioning of the optical lens. The need for repeated adjustment and calibration reduces the operational efficiency of the optical lens production. At the same time, during the positioning process, it is difficult to adjust the up and down directions due to directional limitations, which seriously limits the quality of the optical lens production and processing.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 5 A positioning device for optical lens production includes a rectangular base 1 on which a sliding rod 2 is fixedly installed and a trough frame 5 with upper and lower openings. A roller 4 is provided on one side of the sliding rod 2, and the frame 5 is slidably mounted on the sliding rod 2 and can slide up and down.

[0023] A positioning assembly for positioning the optical lens is provided in the frame 5. The positioning assembly includes a fixing plate 23 fixedly mounted on the surface of the frame 5. The fixing plate 23 is located at the center of the surface of the frame 5, and a circular vertical rod 6 is fixedly mounted under the fixing plate 23. A cylindrical hollow rod 7 is slidably mounted on the vertical rod 6. The hollow rod 7 can slide on the vertical rod 6. Limit rods 8 are symmetrically provided on both sides of the hollow rod 7, and the limit rods 8 can rotate relative to the hollow rod 7. A driven rod 9 is rotatably mounted on the limit rod 8.

[0024] A first support rod 10 is symmetrically arranged in the frame 5. The first support rod 10 is located at both sides of the frame 5, and a deflection rod 11 is rotatably mounted on the first support rod 10. The deflection rod 11 can deflect around the first support rod 10. One end of the driven rod 9 is rotatably connected to the limiting rod 8, and the other end of the driven rod 9 is fixedly mounted to the deflection rod 11. When the deflection rod 11 rotates, the driven rod 9 also deflects, and at the same time drives the limiting rod 8 to rotate;

[0025] A telescopic cylinder 12 is provided in the frame 5, and both ends of the telescopic cylinder 12 are connected to the deflection rod 11. When the telescopic cylinder 12 moves, it will drive the deflection rods 11 on both sides to deflect and move to the sides. The ends of the deflection rods 11 are rotatably mounted with transverse push rods 13. The deflection of the deflection rods 11 will also drive the transverse push rods 13 to move transversely.

[0026] A sliding groove 15 is provided on the surface of the fixed plate 23, and a positioning block 14 for positioning the optical lens is slidably installed in the sliding groove 15. One end of the transverse push rod 13 is rotatably connected to the deflection rod 11, and the other end of the transverse push rod 13 is rotatably connected to the positioning block 14. Therefore, when the deflection rod 11 pushes the transverse push rod 13 to move laterally, the positioning block 14 will also move inward.

[0027] The frame 5 is provided with a lifting assembly that cooperates with the sliding rod 2. The lifting assembly includes a second support rod 16 rotatably mounted in the frame 5. A turntable 21 is fixedly mounted on the end of the second support rod 16, and a handle 22 is fixedly mounted on the turntable 21. When the handle 22 is rotated, the second support rod 16 will also rotate.

[0028] A driving roller 17 is fixedly mounted on the second support rod 16, and a third support rod 18 is rotatably mounted in the frame 5, and a driven wheel 19 corresponding to the driving roller 17 is fixedly mounted on the third support rod 18. When the driving roller 17 rotates, it will also drive the driven wheel 19 to rotate accordingly. A meshing gear 20 is fixedly mounted on the third support rod 18, and the meshing gear 20 will rotate with the rotation of the driven wheel 19. A guide rack 3 meshing with the meshing gear 20 is provided on the sliding rod 2. When the meshing gear 20 rotates, it will form an opposite force with the guide rack 3 to push the meshing gear 20 itself to move upward, thereby driving the positioning assembly to move upward.

[0029] It should be noted that the specific model and specifications of the telescopic cylinder 12 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0030] The functional principle of this utility model can be explained through the following operation modes:

[0031] Place the optical lens between the two positioning blocks 14, extend the telescopic cylinder 12, and drive the deflection rod 11 to deflect around the first support rod 10. At the same time, the limiting rod 8 will limit and support the deflection rod 11 through the driven rod 9. The rotation of the deflection rod 11 will promote the lateral movement of the transverse push rod 13, and the transverse push rod 13 will drive the positioning block 14 to slide laterally, thereby realizing the positioning of the optical lens.

[0032] When adjusting the height up and down, turn the handle 22. The rotation of the handle 22 will drive the rotation of the turntable 21, and the turntable 21 will drive the second support rod 16 to rotate. The second support rod 16 will drive the driving roller 17 to rotate, and the driving roller 17 will drive the driven wheel 19 to rotate. The rotation of the driven wheel 19 will drive the internal meshing gear 20 to rotate. When the meshing gear 20 rotates, it will form an upward or downward force with the guide rack 3, thereby driving itself and the positioning assembly to move up and down.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
