Field of the Invention The present invention relates to a suction nozzle for sucking a lens, and a suction device having the same. [Prior Art] With the development of multimedia technology, digital cameras, cameras and other camera devices are increasingly favored by consumers. In the existing camera device, such as a digital camera, the lens module is generally composed of a lens barrel and an optical lens contained in the lens barrel. See Edward H. Adelson et al., IEEE Transactions on Pattern Analysis and Machine Intelligence, Vol. Single Lens Stereo with a Plenoptic Camera on No. 2, February 1992. Due to the miniaturization of the lens module, the size of the lens is getting smaller and smaller, and as the product is diversified, the type of outer diameter of the lens increases. In the automated manufacturing process of the lens module, a nozzle is used to perform a process such as a zero-lens gate cutting tray or a lens module assembly. Generally, the size of the adsorption holes of the nozzles used in the above process is specifically designed for the outer diameter and the aspherical diameter of the lens to be processed, so that it can be applied to a specific size to be processed. lens. If the size of the lens to be processed changes, it is necessary to redesign the nozzle having the appropriate size of the adsorption hole according to the new size of the lens to be processed. In view of the above, it is necessary to provide a suction nozzle suitable for sucking a plurality of lenses of different sizes and a suction device having the same.

Compared with the prior art, the suction nozzle and the suction device having the same have a plurality of different sizes because of the adsorption holes which are through the stepped holes of the nozzle body, and the stepped holes have a plurality of different diameters. The size of the lens. [Embodiment] Hereinafter, embodiments of the present invention will be further described in detail with reference to the accompanying drawings. Referring to FIG. 1, a nozzle 1 package 200927627 according to a first embodiment of the present invention includes a body 11 and an adsorption hole 12. The body 11 is generally cylindrical in shape and includes two opposing first and second end faces 112. The material of the body 11 may be a hard material such as metal. The adsorption hole 12 is disposed on the body 11 and penetrates through the first end surface 110 and the second end surface 112 of the body u. The adsorption hole 12 is a stepped hole having a first-order hole 121, a second-order hole 122, a third-order hole 123, and a fourth-order hole 124 whose diameter decreases from the first end surface 110 to the first end surface 112 in this order. The diameters of the first-order hole 121, the second-order hole 122, the third-order hole 123, and the fourth-order hole 124 are 4, 1, 10, and Α, respectively. Since the adsorption hole 12 is used for adsorbing the lens to be processed, the steps of the adsorption hole 12 are generally arranged to be holes having a shape matching with the lens to be processed, such as the first-order holes 121 of the adsorption hole 12 in this embodiment (ie, the first-order hole 121, The second-order holes 122, the third-order holes 123, and the fourth-order holes 124) are circular holes. Since the suction hole 12 of the nozzle 10 has a diameter of a plurality of different sizes, the nozzle 10 is suitable for sucking a plurality of lenses of different sizes, for example: © See FIG. 2 'When the nozzle 10 is used, the outer diameter is di In the case of the lens 30, the outer edge of the lens 30 will be held by the hole wall having the diameter of the one-step hole 121, and at least a part of the entire lens 30 is received by the adsorption hole 12, thereby providing vacuum to the adsorption hole 12. During operation, the lens 3 will be sucked up. Similarly, when the nozzle 10 is used to suck the lens having the outer diameter d2, the outer edge of the lens is held by the wall of the second-order hole 122 having the diameter d2, and at least part of the entire lens is received by the adsorption hole 12. When the nozzle 10 is used to suck the lens with the outer diameter A, the outer edge of the lens will be the diameter d3 3 200927627 and the entire mirror # at least partially trapped by the hole wall of the adsorption step hole 123. The hole 12 is received therein. Preferably, the wall of the hole of the adsorption hole 12 is further provided with a layer of elastic material 13, such as rubber, which acts as a buffer when the nozzle 10 sucks the lens, thereby preventing the nozzle 10 from damaging the lens. Referring to Figures 3 and 4, a second embodiment of the present invention also provides a suction device 2A. The suction device 20 includes a hollow tubular body 21, and a suction nozzle 1 两端 and a suction source 22 which are respectively disposed at both ends of the hollow tubular body 21. The hollow tubular body 21 may have a cylindrical shape, and the inside thereof includes a flow passage 210' through which the airflow can pass, the flow passage 210 communicates with the adsorption hole 12 of the suction nozzle 10, and the hollow tubular body 21 is located at the adsorption hole. The opening diameter of 12 is one side of the smaller diameter. Of course, the shape of the hollow tubular body 21 is not limited to a cylindrical shape, and may be a prismatic shape or other irregular shape. The suction source 22 is in communication with the flow path 210, which may be a vacuum supply means such as a vacuum system. The suction source 22 can provide the hollow tube body 2 with a different degree of vacuum so that the lens can have different suction forces to facilitate holding or placing the lens. It should be noted that the lens 3 to be processed shown in FIG. 2 is a lenticular lens having an outer diameter of &, when at least a part of the lens 30 is received in the one-step hole 121 of the diameter t of the adsorption hole 12, the lens The convex surface of the 3 〇 will be accommodated in the second-order hole 122 of the diameter t of the adsorption hole 12 to avoid damage caused by direct contact with the body 11. Of course, the accommodating space of the second-order hole 122 should be at least large enough to accommodate the lens 3 The convex surface area of the crucible, that is, the depth of the second-order hole 122 is greater than or equal to the height of the convex surface of the lens 30. Therefore, for 9 200927627 - for the outer diameter of the lens 30, the suction hole 12 of the nozzle l should have at least one first-order hole 121 and one second-order hole 122. Considering that the nozzle 1 〇 is at least applied to the lenticular lens having the outer diameter as the center of the heart, the suction hole 12 of the nozzle 1 还 should also include at least one third-order hole 123 for accommodating the protrusion of the lens having the outer diameter d2. Therefore, the adsorption hole 12 is at least a third-order stepped hole, which may also be a fourth-order stepped hole, a fifth-order stepped hole, or the like, that is, the adsorption hole 12 may have three, five or even more different diameters. ❹ In addition, the diameter of each step hole of the adsorption hole 12 can be appropriately designed and adjusted according to the outer diameter of the lens to be processed to meet the needs of a plurality of lenses of different sizes, and the diameter relationship of each step of the adsorption hole 12 is not changed. It is limited to sequentially decrease in the direction from the first end face 110 to the second end face 112, and any diameter change relationship that can achieve the effects of the present invention can be achieved. The shape of the body 11 is not limited to a cylindrical shape, and may be a prism shape or the like. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above is only the preferred implementation method of this issue, and it is not possible to limit the scope of patent application in this case. Equivalent modifications or variations made by persons skilled in the art in light of the present invention are intended to be included within the scope of the following claims.
