Since the optical component is limited to the receiving space during the cleaning process, it will not fall off; after cleaning, the optical component can be easily taken out by simply separating the cover from the body. The funnel-shaped through-hole design increases the fluidity of the cleaning fluid during the cleaning process, thereby increasing the ability of the cleaning fluid to remove dirt from the surface of the optical component and more effectively cleaning the optical components. [Embodiment] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Referring to FIG. 2, a first embodiment of the present invention provides a cleaning fixture 10 for cleaning an optical component. The fixture 10 includes a cover 100, a body 200, and a plurality of receiving spaces 300 for receiving optical components. The material of the tool 10 is one of Ming, Ming alloy, non-recorded steel, titanium alloy, copper and heat engineering plastics, and can be processed by CNC (Computerized • Numerical Control) processing technology. Referring to FIG. 3 and FIG. 4, the cover 100 is provided with a plurality of first through holes 102, and the plurality of first through holes 102 are formed on the cover 100 at a certain distance. The first through hole 102 has a funnel shape. The first through hole 102 has a first opening 104 and a second opening 106 opposite to the first opening 104 and located at the bottom of the funnel-shaped first through hole 102. The first opening 104 The aperture is larger than the aperture of the second opening 106. The funnel-shaped through hole increases the fluidity of the cleaning fluid during the cleaning process, thereby increasing the ability of the cleaning fluid stream to remove the surface of the optical component. In this embodiment, each of the first through holes 102 has a circular cross section perpendicular to the axial direction of the first through hole 102 of 9 200804004. Of course, the cross section of the first through hole 102 in the axial direction perpendicular to the first through hole 102 may also be square, as shown in FIG. 5, or other shapes such as a triangle, a diamond, or the like. The body 200 is provided with a plurality of second through holes 202 corresponding to the plurality of first through holes 102 of the cover 100, as shown in FIG. Each of the second through holes 202 has a circular cross section perpendicular to the axial direction of the second through hole 202, and has a third opening 204 and a fourth opening 206 opposite to the third opening 204. The third opening 204 The aperture is larger than the aperture of the second opening 106. The hole wall of each of the 10 second through holes 202 has an annular protruding support portion 208 between the third opening 204 and the fourth opening 206, and the opening formed by the annular protruding support portion 208 is the fifth opening 210. The supporting portion 208 can be used for supporting the optical component. The second through hole 202 between the supporting portion 208 and the fourth opening 206 is in the shape of an inverted funnel. As shown in FIG. 7, the fluidity of the cleaning liquid during the cleaning process can also be increased. Thereby increasing the ability of the cleaning fluid stream to carry away the surface of the optical component. When the cover 100 is used with the body 200, the second opening 106 10 is closer to the body 100 than the first opening 104, and the second opening 106 is in contact with the third opening 204. Preferably, when the cover 100 is engaged with the body 200, the first opening 104, the second opening 106, the third opening 204 and the fourth opening 206 are concentrically mounted on the jig 10. When the cover 100 and the body 200 are overlapped and cleaned, a plurality of receiving spaces 300 for receiving the optical component to be cleaned are formed in the body 200, and the receiving space 300 defines the optical component to prevent the optical component from being It falls off from the jig 10 during the cleaning process. It should be noted that the cross section of each of the second through holes 20 2 in the axial direction perpendicular to the second through holes 2 0 2 may also be square, as shown in FIG. 8 or other shapes, 200804004 - such as a triangle, a diamond Wait. Preferably, the aperture of the second opening of the first through hole 102 of the cover 100 is the same as the aperture of the fifth opening 210, and the aperture is smaller than the size of the optical element to be cleaned. The aperture of the third opening 204 of the body 200 is larger than the size of the optical component to be cleaned. If the optical component to be cleaned is circular, the aperture of the second opening 106 of the first through hole 102 is the same as the aperture of the fifth opening 210, and both are smaller than the diameter of the circular optical element, and the aperture of the third opening 204 It is larger than the diameter of the circular optical element. In addition, when the cover 100 is used in conjunction with the beta body 200, the distance between the third opening 204 and the fifth opening 210 should be greater than the thickness of the optical component to be cleaned in order to accommodate the optical component to be cleaned. For example, for an optical component to be cleaned having a diameter of 3.5 millimeters (mm) and a thickness of 0.3 mm, the aperture of the second opening 106 of the first through hole 102 of the cover 100 may be designed to have a diameter equal to 3.2 ± 0.1 mm, and the second pass The aperture of the third opening 204 of the aperture 202 is designed to have a diameter equal to 3.7 ± 0.1 mm, and the aperture of the fifth opening 210 is designed to have a diameter equal to 3.2 ± 0.1 mm. The distance between the third opening 204 of the 10th through hole 202 and the fifth opening 210 is larger than the thickness of the optical element to be cleaned, for example, the distance between the third opening 204 and the fifth opening 210 is 0.6 ± 0.1 mm. In order to avoid the displacement or falling off of the cover 100 and the body 200 when cleaning the optical component, four first screw holes 108 may be formed in the four corners of the cover 100, as shown in FIG. 4, and the body 200. Four second screw holes 212 corresponding to the four first screw holes 108 are opened, as shown in FIG. 6, and finally four corners are locked by screws 400 and nuts 500, as shown in FIG. The relative position of the cover 100 and the body 200 ensures the cleaning process

Of course, other means can be used to fix the relative position of the cover 100 to the body 2 (10), such as sandwiching the cover 100 with the body 200 by a plurality of clips 600, as shown in FIG. Referring again to FIG. 9 and FIG. 10, before cleaning the glass or plastic lens 20, or other optical components, first, the optical component 20 to be cleaned is placed into the body 200 from the third opening 204 of the second through hole 202. The support portion 208 is configured to support the optical component 20, and then the cover 100 and the body 200 are stacked and the second opening 106 of the first through hole 102 is further connected to the first opening 104. The opening 106 is in contact with the third opening 204, and the relative position of the cover 100 and the body 200 is fixed by the fixing means or other fixing means. The jig 10 provided in the embodiment has an opening of a different aperture formed in the main body 200, and the cover 100 cooperates with the body 200 to form a receiving space 300 for receiving the optical component 20 to be cleaned. The optical component 20 is in the receiving space. There is space for movement in the 300, which does not block the flow of the cleaning liquid, so that the optical component 20 can be completely contacted with the cleaning liquid during the cleaning process, so that it can be thoroughly cleaned, and the cleaning cleanliness and yield are improved. Since the optical element 20 is defined in the accommodating space 300 during the cleaning process, it does not fall off. After the cleaning is completed, the optical element 20 can be easily taken out by simply separating the cover 100 from the body 200. The funnel-shaped through-hole design increases the fluidity of the cleaning solution during the cleaning process, thereby improving the ability of the cleaning fluid stream to carry away the dirt on the surface of the optical element 20, and more effectively cleaning the optical element 20. 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 embodiment of the present invention.
