[0026] Embodiment 1

[0027] This embodiment provides a vacuum adsorption device for optical lenses. Figure 1 As shown, it includes a suction pen 10, an air supply pipe 11 and a negative pressure providing device 12, wherein the negative pressure providing device 12 uses a pressure tank in the prior art, which stores negative pressure gas with a certain pressure, and the negative pressure therein is selected according to the strength of adsorption required, and the strength of adsorption is determined by the size and mass of the adsorbed lens. A connector is provided on the negative pressure providing device 12, and one end of the air supply pipe 11 is detachably connected to the connector on the negative pressure providing device 12, and the other end of the air supply pipe 11 is detachably connected to the rear end of the suction pen 10.

By adsorbing optical lenses with negative pressure, it can effectively solve the problems in the prior art that small-sized optical lenses are difficult to pick up, and that marks, offset printing, dirt, etc. will be generated on the lens surface when picking up.

[0028] Embodiment 2

[0029] This embodiment provides a vacuum adsorption device for optical lenses. Figure 2 As shown, the suction pen 10 includes a suction nozzle 1, a pen holder 2 and an air valve 3. The suction nozzle 1 is detachably mounted on the front end of the pen holder 2, so that the suction nozzle 1 can be conveniently replaced according to the use requirements. The air valve 3 is arranged at the rear end of the pen holder 2, and is used to control the air flow in the suction nozzle 1, and is used to suck and put down the optical lens. Specifically, in this embodiment, the diameter of the suction nozzle 1 is 8mm-20mm, the length of the suction nozzle 1 is 10mm-30mm, and the length of the suction pen 10 is 50mm-200mm, which is convenient for handholding. The suction pen 10 is a suction pen made of wear-resistant material, and materials such as POM engineering plastics in the prior art can be used. It has the characteristics of high hardness, high rigidity, and high wear resistance. It is not easy to leave marks or be scratched when in contact with optical lenses made of plastic or glass.

[0030] Reference Figure 3 , Figure 4As shown, the nozzle 1 comprises an integrally formed head 14 and a connecting portion 15 , an air flow channel 16 is provided in the center of the head 14 and the connecting portion 15 , and the diameter of the air flow channel 16 is 3 mm to 5 mm. The connecting portion 15 is mounted at the front end of the pen holder 2 .

[0031] Embodiment 3

[0032] Reference Figure 4 , Figure 5 As shown, the front end of the head 14 of the suction nozzle 1 can be horizontal, or can be provided with a receiving groove 161, which is connected to the airflow channel 16. When the head 14 of the suction nozzle 1 is a plane, it is mainly used for adsorbing aspherical lenses. When the head 14 of the suction nozzle 1 is provided with a receiving groove 161, it is used for adsorbing spherical lenses, wherein the size of the receiving groove 161 is adapted according to the size and curvature of the spherical lens. Preferably, the cross-section of the side wall of the receiving groove 161 at the front end of the head 14 is an arc convex outward.

[0033] The following is an explanation of the selection of nozzle 1 using a spherical lens as an example. Figure 6 The meniscus spherical lens shown includes a convex surface S1 and a concave surface S2, the curvature of the convex surface S1 is C1 = 1 / R1; the curvature of the concave surface S2 is C2 = 1 / R2, and the size of the receiving groove 161 is selected according to the curvature of the lens adsorption surface S1 or S2. The larger the curvature of the adsorption surface of the lens, the larger and deeper the receiving groove 161 needs to be. By selecting different types and sizes of suction nozzles 1, it is possible to meet the adsorption of lenses of various types and curvatures, and by size adaptation, the lens can be better adsorbed and tightened during the adsorption process.
