Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a lens and a method of processing the same. [Prior Art] [0002] Lenses are widely used in various optical instruments such as projectors, cameras, microscopes, and telescopes. Most of these optical instruments combine a plurality of lenses and assemble them in an optical lens barrel. Therefore, the accuracy of these optical instruments is closely related to the processing precision and assembly technology of the lens. Among them, the centering of the lens is the most important. 1 is a schematic view of a lens 10 in a centering work fixture 12. Referring to FIG. 1 , during the centering process of the lens 10 , the lens 10 is usually clamped by the clamp 12 , and then the lens 10 is rotated by the clamp 12 , and the outer diameter of the lens is ground by the grinding wheel 14 , wherein the grinding wheel 14 is The rotating shaft is parallel to the rotating shaft of the jig 12. When the jig 12 and the lens 10 are stably rotated with the central axis C of the jig 12 as an axis, the lens center of the lens 10 is located on the central axis of the jig 12. At this time, the processing of the lens 10 can be performed, and the geometric center of the processed lens 10 will be located on the connecting line between the curved surface 100 of the lens 10 and the axis of the curved surface 102. This centering mechanism, which may also be referred to as an outer diameter grinding machine, is widely used for rounding or rounding of a general shape. [0004] However, the concentricity of lenses processed by this conventional processing method is somewhat different, so that the yield of most lens factory assembly cannot be effectively improved. SUMMARY OF THE INVENTION [0005] In view of the above, it is necessary to provide a lens capable of improving assembly yield and a processing method thereof. 095115269 Form No. A0101 Page 3 / Total 16 Page 1003354408-0 1354601 [0006] [0009] [0011] [0011] Correction of the replacement page - the processing method of the lens, including The following steps: holding a lens with a clamp and rotating it; making the grinding wheel reciprocate along the direction of the clamp _ line to grind the outer diameter of the money to the size required by the specification; keeping the clamp stationary, the grinding wheel moving toward the lens and along The clamping assembly _ reciprocates in the line direction to grind the edge of the lens to a concave corner. The present invention also proposes a lens having an edge having at least one concave angle relative to the prior art 'the lens that is reinforced by the method of assembly is found to be inferior when assembled. 'The caller or other device can be inserted into the concave corner. The lens makes it rotate - the angle is fixed, and the difference between the four (four) and the fourth (four) is easier to find the position that can best understand the best performance, so that (4) the yield can be improved 'cost saving. [Embodiment] Hereinafter, the present invention will be further described in detail with reference to the accompanying drawings. The present embodiment provides a processing method for processing a lens. Referring to FIG. 2 to FIG. 5, a lion is provided, and a through hole (four) to be processed, that is, a first clamping component 22 and a second clamping component 24 are provided. The lens 28 has a first surface 280 and a second surface opposite thereto. The first clamping portion m of the first clamping component 22 abuts on the first surface 280 of the lens 28, and the axis of the first defective 00ft surface 280 of the lens 28 rotates with the first clamping component 22 The axis C' coincides. The clamping surface 222 of the first clamping portion 220 is generally in close contact with the first side of the lens 28 and the surface of the second surface 28〇' to prevent the lens from tilting during processing. [0012] 095115269 The first clamping assembly 24 The second clamping portion 24 abuts the second table form number of the lens 28 A0101 page 4 / a total of 6 pages 1003354408-0 13.54601 [0013] [0015] [0016] [0017] 095115269 100 years 09 The replacement page 282 is modified on the 27th of the month to hold the lens 28 together with the first clamping assembly 22. The first clamping assembly 22 and the second clamping assembly 24 are caused to rotate the lens 28 with the rotation axis C of the first clamping assembly 22. The wheel plate 26 is reciprocated in the axial direction of the clamp assemblies 22, 24, and the outer diameter of the lens 28 is ground to the required size. The wheel plate 26 includes a tip 262' which is opposite the lens 28, the end line 264 (not shown) of the tip 262 being parallel to the axes of the clamps 22, 24 and facing the lens 28 during processing. The lost holding assemblies 22, 24 remain stationary and the grinding wheel plate 26 moves toward the lens 28 and reciprocates in the axial direction of the clamping assemblies 22, 24, grinding the edges of the lens 28 out of the first concave corner 284. In a preferred embodiment of the present invention, after the first clamping portion 220 of the first clamping assembly 22 is abutted against the first surface 280 of the lens 28, the first clamping assembly 22 and the lens 28 are A negative pressure space is formed between the lens 28 to be attracted to the first clamping assembly 22, for example, by using the air vent 224 of the first clamping assembly 22 to extract air between the first clamping assembly 22 and the lens 28. Negative pressure space. The present invention can also apply a lubricant to the lens 28 prior to abutting the clamping surface 222 of the H-th component 22 against the first surface 280 of the lens 28 to avoid the first clamping assembly 22 from being processed. The lens 28 is injured. Then, in the subsequent process of forming the negative pressure space, the lubricant on the lens 28 helps to reduce the amount of gas remaining between the first clamping unit 22 and the lens 28 to increase the negative pressure effect, thereby increasing the lens 28. The adsorption force with the first clamping member 22. Form No. A0101 1003354408-0 1354601 September 27, 2007 Nuclear Replacement Page [0018] wherein the second clamping assembly 24 is preferably a soft clamping assembly. The outer shape of the second clamping portion 240 of the second clamping assembly 24 may vary depending on the curved surface it contacts to avoid lensing due to uneven application during the abutment of the second surface 282 of the lens 28. The offset or tilt of 28, which in turn affects the accuracy of the processing of lens 28. [0019] The lens processing method of this embodiment may further include the following steps: [0020] The grinding wheel plate 26 is moved away from the lens 28, and the grinding wheel plate 26 is kept stationary. [0021] The first clamping component 22 and the second clamping component 24 are jointly driven to rotate the lens 28 by a certain angle with the rotation axis C′ of the first clamping component 22 such that the position of the first concave corner 284 is not in its original position. coincide. [0022] With the clamping assemblies 22, 24 held stationary, the grinding wheel plate 26 moves toward the lens 28 and reciprocates in the axial direction of the clamping assemblies 22, 24, grinding the edges of the lens 28 out of the second concave corner 286. [0023] Although the lens is only ground to two concave corners in this embodiment, those skilled in the art can easily use the method to grind a plurality of concave corners to facilitate various uses. Moreover, the processed components are not limited to lenses, and the present invention is applicable to the spheronization and optical component processing of various thin plates. Referring to FIG. 6, the present invention also provides a special shaped lens 30 processed by the above method, the edge of the lens 30 having at least one concave corner 32. [0025] Compared to the prior art, the lens 30 processed by the processing method can be used to insert the concave corner 32 to rotate the lens 30 to rotate a certain angle by using a tweezers or other device after the assembly is found to be inferior in performance. 095115269 Form No. A0101 Page 6 / Total 16 Page 1003354408-0 1354601 September 27th, 100th Shuttle Order [0026] [0028] [0030] [0033] [0033] [0037] [0037] It is easier to find a location where the best performance can be obtained, so that the assembly yield can be improved and the cost can be saved.
