[0039] As Figures 1-5 The utility model discloses a positioning device for optical lens production, including positioning table 1, fixed with adsorption platform 2 on positioning table 1, the four corners of the bottom of positioning table 1 are all fixed with support rod 3, the surface of support rod 3 is equipped with negative pressure mechanism 4, wherein, the surface of adsorption platform 2 is equipped with adsorption groove 21, a plurality of adsorption groove 21 all communicate with negative pressure mechanism 4, and the adsorption groove 21 can be made into negative pressure state for the adsorption positioning of optical lens under the action of negative pressure mechanism 4;

[0040] The negative pressure mechanism 4 includes a driving part 41 and a negative pressure part 42, wherein the negative pressure part 42 includes a shell 423, a first negative pressure ring 420, a second negative pressure ring 421 and a third negative pressure ring 422 arranged in the shell 423, and the first negative pressure ring 420, the second negative pressure ring 421 and the third negative pressure ring 422 are concentrically arranged from inside to outside and fixed with the top wall of the shell 423.

[0041] The adsorption groove 21 has a plurality of first adsorption groups 210, second adsorption groups 211 and third adsorption groups 212 corresponding to the first negative pressure ring 420, the second negative pressure ring 421 and the third negative pressure ring 422, and the minimum size of the optical lens is greater than the outer diameter of the first adsorption group 210 in actual application. When the optical lens is placed in the center of the adsorption platform 2 for adsorption, at least one adsorption group of the optical lens can be guaranteed to perform adsorption, and when the lens is larger, the second adsorption group 211 and the third adsorption group 212 can be extended to the outside for adsorption, thereby improving the adsorption strength when positioning the larger lens, and ensuring the stability during the adsorption process.

[0042] The first adsorption group 210, the second adsorption group 211 and the third adsorption group 212 are connected to the first negative pressure ring 420, the second negative pressure ring 421 and the third negative pressure ring 422 through the through groove 424 on the housing 423.

[0043] Pistons 425 are slidably provided inside the first negative pressure ring 420, the second negative pressure ring 421 and the third negative pressure ring 422. A pull rod 426 is fixed to the bottom of the piston 425, and a pull plate 427 is fixed to the bottom of the pull rod 426. The outer side of the piston 425 is in close contact with the inner side of the first negative pressure ring 420, the second negative pressure ring 421 and the third negative pressure ring 422.
