[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0016] Referring to FIG. 2 , an embodiment of the present invention provides a jig 10 , the jig 10 includes a cover 12 and a body 14 . The material of the jig 10 is one of aluminum, aluminum alloy, stainless steel, titanium alloy, copper and heat-resistant engineering plastics, and the jig 10 can be manufactured using CNC (Computer Numerical Control) processing technology.
[0017] As shown in FIG. 3 and FIG. 4 , the cover body 12 is provided with a plurality of first through holes 122 and the four corners are respectively provided with first screw holes 126 . The plurality of first through holes 122 are arranged on the cover body 12 in a matrix form with a certain distance therebetween. Optionally, the first through holes 122 are distributed on the cover body 12 in a honeycomb shape.
[0018] In this embodiment, the plurality of first through holes 122 are circular holes. Certainly, the first through hole 122 may also be a square hole, a triangular hole, or a rhombus hole.
[0019] Adjacent first through holes 122 are connected by first grooves 124 , so that the first through holes 122 are distributed in a network.
[0020] As shown in FIGS. 5 and 6 , the body 14 defines a second through hole 142 corresponding to the first through hole 122 and a second screw hole 146 corresponding to the first screw hole 126 .
[0021] The second through hole 142 is a circular hole and has a first opening 1421 and a second opening 1422 . The diameter of the first opening 1421 is larger than that of the first through hole 122 and the diameter of the second opening 1422 .
[0022] Adjacent first openings 1421 are connected by second grooves 144 , so that the second through holes 142 are distributed in a network.
[0023] When the cover 12 is used with the body 14 , the first opening 1421 is closer to the cover 12 than the second opening 1422 . When the cover 12 is mated with the main body 14 , the first opening 1421 and the second opening 1422 are concentrically opened in the main body 14 , and the second through hole 142 and the first through hole 122 are concentrically opened on the jig 10 .
[0024] The cover 12 and the main body 14 are fixed by screws through the first screw hole 126 and the second screw hole 146 , thereby fixing the relative position of the cover 12 and the main body 14 to ensure the smooth completion of the cleaning process.
[0025] The aperture of the first through hole 122 of the cover body 12 is the same as the aperture of the second opening 1422, and the aperture is smaller than the size of the optical element 20 to be cleaned, while the aperture of the first opening 1421 of the body 14 is smaller than the size of the optical element 20 to be cleaned. The size of the element 20 is large.
[0026] If the optical element to be cleaned is circular, the apertures of the first through hole 122 and the second opening 1422 will be smaller than the diameter of the circular optical element 20, and the aperture of the first opening 1421 will be smaller than the diameter of the circular optical element 20. Large diameter. In addition, when the cover 12 is used in conjunction with the main body 14 , in order to accommodate the optical element 20 to be cleaned, the depth of the first opening 1421 should be greater than the thickness of the optical element 20 to be cleaned. For example, for the optical element 20 to be cleaned with a diameter of 3.5 millimeters (mm) and a thickness of 0.3 mm, the aperture of the first through hole 122 of the cover body 12 can be designed to have a diameter equal to 3.2 ± 0.1 mm, and the first through hole 142 of the second through hole 142 The aperture of the opening 1421 is designed to have a diameter equal to 3.7±0.1 mm, and the aperture of the second opening 1422 is designed to have a diameter equal to 3.2±0.1 mm. The depth of the first opening 1421 is greater than the thickness of the optical element 20 to be cleaned, for example, the depth of the first opening 1421 is 0.6±0.1 mm, and the depth of the second opening 1422 is 0.6±0.1 mm.
[0027] As shown in FIG. 7 , when the cover 12 and the main body 14 are stacked and used together, a plurality of storage spaces 110 for accommodating the optical components 20 to be cleaned will be formed in the main body 14, and the storage spaces 110 limit the optical components 20 , so as to prevent the optical element 20 from falling off from the second opening 1422 of the first through hole 122 or the second through hole 142 .
[0028] When cleaning the optical element 20, first, put the optical element 20 to be cleaned into the main body 14 from the first opening 1421 of the second through hole 142, then stack the cover 12 and the main body 14 and make the second through hole The first opening 1421 of the hole 142 is closer to the cover 12 than the second opening 1422 , and then the relative positions of the cover 12 and the main body 14 are fixed by the aforementioned fixing means or other fixing means.
[0029] Since the cover body 12 and the body 14 have corresponding first through holes 122 and second through holes 142 in position, water flow or other cleaning fluids can not only take away the dirt on the surface of the optical element 20 to be cleaned in the vertical direction, but also because the adjacent The first through holes 122 communicate with each other, and the second through holes 142 communicate with each other, so that the dirt on the surface of the optical element 20 can flow to the side, and the dirt on the surface of the optical element 20 is increased in the direction parallel to the optical element 20. The opportunity to be taken away by water or other cleaning fluids improves the cleaning efficiency and cleanliness of optical components.
[0030] In addition, those skilled in the art can also make other changes within the spirit of the present invention. Of course, these changes made according to the spirit of the present invention should be included within the scope of protection claimed by the present invention.
