Description of the Invention: [Technical Field of the Invention] The present invention relates to a lens bearing jig. [Prior Art] With the development of optical products, the application range of optical lenses is becoming wider and wider. Accordingly, the industry uses a variety of methods to fabricate optical lenses to accommodate the market demand for different specifications of optical lenses (see Fabrication of Diffractive Optical Lens for Beam splitting Using LIGA 〇 Process), Jauh Jung Yang; Mechatronics and Automation, Proceedings of the 2006 IEEE International Conference on > pp. 1242-1247, 2006.06). At the same time, in order to reduce costs and improve efficiency, mass production is carried out to meet the demand for optical lenses. In general, manufactured optical lenses require subsequent processing to achieve good performance for the application. In the process of forming the lens, it is generally necessary to provide a bearing fixture. Previous bearing fixtures generally included a body and a cover. The body has a receiving hole for carrying the lens, the cover body has a through hole matched with the receiving hole, the body and the cover body hold the lens for fixing the lens, and the intermediate optical portion of the lens is exposed outside the through hole of the cover body to ensure The subsequent steps are carried out. However, the fixing of the lens depends on the size of the receiving hole and the degree of cooperation between the body and the cover. If the shape of the lens is not well matched with the receiving hole, the lens may sway, rotate, etc., which seriously affects the subsequent process, and even the lens is damaged. 5 201020186 [Summary of the Invention] It is necessary to provide a lens-loading fixture that is easy to fix the lens. A lens bearing fixture comprising a plurality of carrier units. Each carrier unit includes a hollow body and a receiving hole. The hollow body has a first surface that forms a cavity. The receiving hole is formed on the first surface of the hollow body and extends into the hollow body and communicates with the cavity of the hollow body, the receiving hole is for receiving the lens. The cavity of the hollow body of the plurality of load bearing units is for communicating with a vacuuming device. Compared with the prior art, the lens carrying fixture is placed in the receiving hole during use, and the cavity of the hollow body can be vacuumed by a vacuuming device to form a low pressure region to attract the lens. In the lens cleaning process, the lens can be fixed in the fixture only by maintaining the pressure difference between the cavity of the hollow body and the outside, and the adsorption force can effectively prevent the lens from shaking and rotating. The lens bearing fixture is easy to fix the lens and has a simple structure. [Embodiment] Hereinafter, embodiments of the present invention will be further described in detail with reference to the accompanying drawings. ,. Referring to Figures 1 and 2, a lens carrying tool 100 according to a first embodiment of the present invention includes a plurality of carrier units 10. /α In the present embodiment, the lens carrying jig 100 includes a plurality of carrier unit groups 1〇1 arranged in parallel in the first direction. Each of the carrying unit groups includes a plurality of load carrying units connected in sequence, and thus, the loading unit 6 201020186 sets the plurality of carrying units 10 arranged in an array. Each of the carrying units 10 includes a hollow body 12 and a receiving hole 141. The hollow body 12 has a first surface 121 and a second surface 122 opposite the first surface 121. The hollow body 12 defines a cavity 123. Preferably, the cavity 123 of the hollow body 12 is filled with a capillary structure 13. In the present embodiment, the capillary structure 内部 13 inside each of the carrier unit groups 101 penetrates each other. The capillary structure 13 is a porous structure sintered from metal, and the metal may be iron, aluminum, copper, nickel, and cobalt or an alloy of any two or more of the above metals. Of course, the capillary structure 13 can also be other structures, such as a porous fiber structure. The communication structure of the capillary structure 13 inside the plurality of carrying units 10 may also be in other forms, such as a honeycomb shape or a mesh shape. The plurality of cavities 123 of the plurality of carrying units 10 included in the lens carrying jig 100 are in communication with an evacuating device 20. Preferably, the mirror-carrying jig 100 further includes an air suction tube 11. The suction pipe 11 communicates with the cavity 123 of each of the carrier unit groups 101. In the present embodiment, the suction duct 11 communicates with the capillary structure 13 in each of the load bearing units 10. The vacuuming device 20 is in communication with the suction pipe 11. It can be understood that the suction pipe 11 and the capillary structure 13 can also be in other forms. When the capillary structures 13 of the plurality of load bearing units 10 are in a honeycomb or mesh shape, the suction pipes 11 can communicate with each other. One of the plurality of carrying units 10 or the capillary structures 13 of the plurality of carrying units 10 are in communication to carry all of the carrying units included in the jig 100 directly or indirectly with the lens 7 through the interconnected capillary structure 13 201020186 The capillary structure 13 of 10 is connected. And the suction pipe 11 can also extend to the inside of the capillary structure 13. The receiving hole 141 is formed in the first surface 121 of the hollow body 12 and extends into the hollow body 12 for receiving the lens. In the embodiment, the receiving hole 141 extends into the cavity 123 to communicate with the capillary structure 13. Preferably, the hollow body 12 further includes a through hole 142 formed in the second surface 122 of the hollow body 12 and passing through the receiving hole 121. The aperture of the receiving hole 141 is larger than the aperture of the through hole 142, so that an interface 140 is formed at the interface between the receiving hole 141 and the through hole 142. The receiving hole 141 extends to the capillary structure 13. The capillary structure 13 is partially exposed to the through hole 142. Preferably, in the embodiment, the inner wall of the through hole 142 is sealed by the sealing structure 15 to prevent the lens bearing jig 100 from leaking when vacuuming. At the same time, the sealing structure 15 is also resistant to the pressure generated when vacuuming. The sealing structure 15 is generally a coating layer coated with a coating. ❿ It can be understood that the suction pipe 11 can also be disposed at any other position of the carrying unit 10. Of course, in order to evacuate the inside of the capillary structure 13, the intake pipe 11 may be provided in plural. The lens 16 has an intermediate optic 161 and a peripheral support 162. When the lens is used to carry the jig 100, the lens 16 is placed in the receiving hole 141, and the peripheral supporting portion 162 of the lens 16 abuts against the interface 140. After the air in the capillary structure 13 is extracted from the suction pipe 11 by the vacuuming device 20, the sealed capillary structure 13 forms a low pressure region, which generates a pressure difference with the air near the peripheral support portion 162 of the mirror 8 201020186. A force that adsorbs the lens 16 is created, and at the same time, the sealing structure 15 produces a supporting force on the lens 16. Thus, the lens 16 can be secured to the lens bearing fixture 100. During the processing of the lens 16, the lens 16 can be secured within the lens-carrying jig 100 by simply maintaining the pressure difference between the cavity 123 and the outside. After the lens is processed, the air is sucked into the air suction tube 11 by the vacuuming device 20, and the pressure difference between the capillary structure 13 and the outside is eliminated to remove the lens 16. The lens bearing fixture 100 is easy to fix the lens, and prevents the mirror 15 from being shaken and rotated in the receiving hole 141, and the lens bearing fixture 100 has a simple structure. In this embodiment, the capillary structure 13 filled in the cavity 123 and the sealing structure 15 disposed on the inner wall of the through hole 142 can further maintain the pressure difference between the cavity 123 and the outside, so that the lens 16 is well fixed. The lens is carried in the jig 100. It can be understood that when the thickness H1_ of the peripheral supporting portion 162 of the lens 16 is smaller than the thickness H2 of the receiving hole 141 extending to the capillary structure 13, the inner wall of the receiving hole 141 exposed to the outer wall is also sealed by the sealing structure 15. In order to prevent the lens bearing jig 100 from leaking when vacuuming. Referring to Figure 3, a lens carrying fixture 200 is provided in accordance with a second embodiment of the present invention. The lens carrying jig 200 is substantially identical in construction to the lens carrying jig 100 of the first embodiment, and the lens carrying jig 200 includes a plurality of loading units 201. The embodiment is different from the first embodiment in that the receiving hole 241 is formed on the first surface 221 of the hollow body 22. The depth 9 of the receiving hole 241 is less than the depth of the inner wall of the hollow body 22. The lens carrying jig 200 further includes a through hole 242. The receiving hole 241 communicates with the cavity 223 through the through hole 242. The receiving hole 241 is connected to the through hole 242 at an interface 240 for carrying the lens 26. Of course, in this embodiment, the receiving hole 241 can also have other shapes, such as a taper or the like. The through hole 242 can also penetrate the second surface 222 of the hollow body 22, and an opening (not shown) is formed on the second surface 222, and a sealing structure is further disposed at the opening. ® Referring to Figure 4, a lens carrying fixture 300 is provided in accordance with a third embodiment of the present invention. The lens carrying jig 300 is substantially identical in construction to the lens carrying jig 100 of the first embodiment, and the lens carrying jig 300 includes a plurality of loading units 30. This embodiment is different from the first embodiment in that each of the carrying units 30 further includes a support portion 37. The support portion 37 is formed on the second surface 322 of the hollow body 32. The support body 37 is used to maintain the lens 36 in the receiving hole 341. The support body 37 is integrally formed with the hollow body 32. Of course, the support body 37 can also have other shapes. The support body 37 can also be fixed to the hollow body 32 by other means, such as bonding 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 description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention. 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.
