Abstract
Description
Technical Field
[0001] The present application relates to the technical field of optical component processing, and more specifically, to a processing method for an optical component having adjacent different processing surfaces. Background Art
[0002] In optical parts, optical parts with adjacent different processed surfaces are used. For example, a plano-concave lens. One side of the plano-concave lens is a spherical arc concave surface and the other side is a plane. The edge of the spherical concave arc surface needs to form a plane platform. Therefore, a plane surface at the outer edge and a spherical concave arc surface in the middle are formed on one side of the plano-concave lens, thereby forming an optical part with adjacent different processed surfaces.
[0003] The above-mentioned adjacent different processed surfaces will interfere with each other during processing, so there are great difficulties in processing, mainly because it is easy to scratch the adjacent processed surfaces. For example: when processing the above-mentioned plano-concave lens, the edge platform surface needs to be polished. When the opening angle of the concave arc surface in the center is less than about 1°, if the concave surface is polished first and then the platform plane is polished, it is very easy to scratch the concave surface, resulting in poor concave surface finish. If the platform plane is polished first and then the concave surface is polished, on the one hand, it is difficult to control the radius and surface shape error, and on the other hand, it is also easy to scratch the finish of the junction between the concave surface and the platform surface.
[0004] Therefore, the prior art still needs to be improved and developed. Summary of the invention

[0024] In an optional embodiment, when the surface requirements of the second forming surface and the first forming surface are the same, both the first forming surface and the second forming surface are polished surfaces, or both the first forming surface and the second forming surface are frosted surfaces.
[0025] In an optional embodiment, in the step of machining the protective layer and the blank of the semi-finished workpiece according to a predetermined path to form a second forming surface on the surface of the protective layer and the blank:

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

"Multiple" means two or more, unless otherwise clearly and specifically defined.
[0040] The following is an explanation of the names involved in this application, as follows:
[0041] Plano-concave lens: An optical component with a negative focal length, usually used to diverge a beam of parallel light. The plano-concave lens has two opposite end faces, of which the first end face on one side is a spherical surface and the second end face on the other side is a plane. The first end face is a spherical arc concave surface, that is, the thickness in the middle of the plano-concave lens is thinner than the thickness at the edge. Moreover, the first end face not only has a spherical concave surface, but often forms a plane platform at the edge of the spherical arc concave surface.
[0042] Spherical angle: the angle between the line connecting the vertex of the sphere and the center of the sphere and the line connecting the outermost point and the center of the sphere.
[0043] like Figure 2 As shown, in the existing processing scheme for the above-mentioned plano-concave lens 400, it is necessary to polish the spherical arc concave surface (the second finished surface 420) and the plane platform at the edge (the first finished surface 410), and this spherical arc concave surface is connected to the plane platform, which interferes with each other during polishing, so it is very easy to scratch the adjacent polished surface during the polishing process. The existing processing scheme can reduce the risk of scratching the adjacent polished surface by adjusting the concentration of cerium oxide in the polishing liquid and using a harder polishing mold. However, when the interference situation is more extreme, that is, in the plano-concave lens 400, the concave surface angle is closer to 0°, resulting in the spherical arc concave surface and the plane platform at the edge The connection tends to be smooth, or in other optical parts, the angle between two adjacent inclined planes and the reference plane is closer to 180°, resulting in the inclined plane and The reference plane The connection is smooth, the existing traditional method can no longer avoid causing poor finish to the polished surface.
[0044] That is, when the first side end face of the optical component is processed, since the first side end face has a connected spherical arc concave surface and a plane platform that both need to be polished, when the spherical angle of the spherical arc concave surface in the center is less than about 1°; or for the first side end face has a connected inclined plane and a reference plane that both need to be polished, when the angle of the two plane polishing surfaces is greater than 179° and close to 180°, because the polishing process is essentially to use fine abrasives to cut and rub the workpiece surface, and the particle size of the polishing auxiliary material is usually at the level of a few tenths of a micron, and since the relative positions of such adjacent surfaces of such optical elements are less than the micron level in a large range, and the relative movement of polishing, scratches are easily formed on such extremely close adjacent surfaces, especially in polishing methods such as mechanical polishing or electrolytic polishing that require physical contact, the risk of scratches on adjacent surfaces is greatly increased.
[0045] In order to solve the problem of the risk of scratches caused by adjacent surface processing in the prior art, a processing method for an optical component with adjacent different processing surfaces is provided through the following embodiments, which can effectively protect such extremely close adjacent surfaces and extend to a large surface to facilitate the processing of the second surface. Therefore, the processing method for an optical component with adjacent different processing surfaces of this scheme can effectively process optical components whose polishing surfaces interfere with each other compared with the traditional method. The specific embodiments are as follows:
[0046] See also Figure 1 , Figure 2 This embodiment proposes a processing method for an optical component with adjacent different processing surfaces, which is used for processing an optical component with adjacent different processing surfaces on one side. This embodiment takes the processing of a plano-concave lens 400 as an example. For example, a certain plano-concave lens 400 product has an outer diameter of Φ30, and the radius of the spherical arc concave surface on its first side end face is 1020mm. The spherical arc concave surface (the second finished surface 420) is located in the middle, and there is a flat platform (the first finished surface 410) that needs to be polished at the edge of the spherical arc concave surface. The caliber of the spherical arc concave surface is Φ10~Φ13.5, from which it can be inferred that the sagittal height of the spherical arc concave surface is about 0.01mm (+0.01 / 0). This processing method for an optical component with adjacent different processing surfaces mainly includes the following steps:
[0047] See also Figure 1 , step S100, providing a blank, and processing a first surface of the blank to obtain a first forming surface.
[0048] See also Figure 3 , a blank 100 is selected, and the blank 100 has machining allowances on both side end surfaces (first surface 101 and second surface 102). The first surface 101 and the second surface 102 opposite to the blank 100 are machined so that the first surface is machined to form a first forming surface 110, wherein the first forming surface 110 meets the predetermined finished product quality standard. The first surface 101 and the second surface 102 are machined in a manner that matches the surface requirements of the finished product to achieve the finished product quality. For example: if the first surface 101 and / or the second surface 102 need to be polished, the first surface 101 and the second surface 102 of the blank 100 are polished; if the first surface 101 and / or the second surface 102 need to be frosted, the first surface 101 and / or the second surface 102 of the blank 100 are frosted. The first forming surface 110 may be an area of the entire first surface of the blank 100 (please refer to Figure 3 , Figure 4 ), or a partial area of the first surface of the blank 100. The area included in the first forming surface 110 needs to be larger than the area of the first finished surface 410 of the finished product (see Figure 5 ).
[0049] Step S200: Covering the first forming surface with a protective layer to obtain a semi-finished workpiece.
[0050] See also Figure 3 , Figure 4 The protective layer 200 may be a protective sheet made of the same or similar material as the blank 100. Therefore, in this step, a protective sheet is provided and bonded to the first forming surface 110, wherein the protective sheet covers the first forming surface 110. By bonding the protective sheet, the processed first forming surface 110 is protected. The protective layer 200 may completely cover the entire first forming surface 110, or partially cover the first forming surface 110 (e.g., Figure 7 As shown, when partially covering, the protective layer 200 may only cover the outer edge area of the first forming surface 110), for example, the area covered by the protective layer 200 needs to be larger than the area of the first finished surface 410 of the finished product.
[0051] See also Figure 6 In another feasible solution, when the first forming surface 110 is formed by processing a partial area of the first surface of the blank 100, a center boss 320 is formed between the middle area of the blank 100 and the first forming surface 110 area, and the protective layer 200 adopts an annular protective sheet. After the protective sheet is bonded to the first forming surface 110 area, the protective sheet is sleeved on the center boss 320, so that the relative positioning of the protective sheet and the blank 100 can be achieved, so that the blank 100 fixed on the first forming surface 110 will not shift during the subsequent processing, making the processing more stable.
[0052] See also Figure 6 In addition, it should be noted that when the first forming surface 110 is formed by machining a part of the first surface, after the center boss 320 is formed between the middle area of the blank 100 and the first forming surface 110, the end surface of the center boss 320 can be machined to match the thickness of the protective sheet with the surface of the first side end surface of the center boss 320, for example, flush. Not only can the machining surface of the first side end surface of the protective sheet during machining form a complete plane, thereby avoiding intermittent machining of the mold and improving the surface quality of the machining; and the surface of the machined center boss 320 can be used as a control reference for the subsequent final size, which is convenient for aligning the end surface before machining, thereby strictly controlling the size and making the final size of the product meet the predetermined requirements.
[0053] Step S300: Processing the protective layer and the blank of the semi-finished workpiece according to a predetermined path to form a second forming surface on the surfaces of the protective layer and the blank, wherein the first forming surface is connected to the second forming surface.
[0054] See also Figure 4 , Figure 5 During the processing, the protective layer 200 and the blank 100 are processed as a whole so that the final size of the product meets the predetermined requirements. That is, the processing continues from one side of the first surface of the blank 100, and the semi-finished workpiece 300 is processed as a whole according to the predetermined path, and the protective layer 200 and the first forming surface 110 of the blank 100 are partially processed to form a connected first forming surface 110 and a second forming surface. The predetermined path can be a polishing path for a spherical arc concave surface, or a bevel polishing path, or various frosting paths, etc., which can be selected according to the actual product processing requirements. During the overall processing, such as Figure 7 As shown in Figure a, the surface of the protective layer 200 can be fully processed, that is, the entire surface of the protective layer 200 is processed; Figure 7 As shown in FIG. b, only a part of the surface of the protective layer 200 may be processed, for example, the area of the surface of the protective layer 200 close to the central axis may be processed away, while the outer edge area of the protective layer 200 may be retained.
[0055] During the specific processing, the shape of the second forming surface is different from or the same as the shape of the first forming surface 110: when the shape of the second forming surface is different from the shape of the first forming surface 110, the second forming surface is arc-shaped, and the first forming surface 110 is plane-shaped. Thus, an optical component structure is formed with a spherical arc concave surface (second finished surface 420) in the middle of the first side end surface and a plane platform (first finished surface 410) at the edge. When the shape of the second forming surface is the same as the shape of the first forming surface 110, the second forming surface is plane-shaped, the first forming surface 110 is plane-shaped, and a predetermined angle is formed between the second forming surface and the first forming surface 110. Thus, an optical component structure with a connected inclined plane and a reference plane on the first side end surface, that is, a roof-shaped optical component structure is formed.
[0056] The surface requirements of the second forming surface 310 and the first forming surface are different or the same: when the surface requirements of the second forming surface 310 and the first forming surface are different, the first forming surface is a frosted surface and the second forming surface 310 is a polished surface; in addition, the first forming surface can also be a polished surface and the second forming surface 310 is a frosted surface. Thus, an optical component structure is formed in which the middle of the first side end surface is a polished surface and the plane platform at the edge is a frosted surface. When the surface requirements of the second forming surface 310 and the first forming surface are the same, the first forming surface and the second forming surface 310 are both frosted surfaces or polished surfaces. Thus, an optical component structure is formed in which the middle of the first side end surface is a polished surface and the plane platform at the edge is a polished surface, or an optical component structure is formed in which the middle of the first side end surface is a frosted surface and the plane platform at the edge is a frosted surface.
[0057] Step S400, removing the protective layer to expose the retained first forming surface to form a first finished surface, and the retained second forming surface on the blank to form a second finished surface.
[0058] See also Figure 5 and Figure 2 In the specific process, the unprocessed protection sheet is directly removed to obtain the unprocessed area of the first forming surface 110, which is the first finished surface 410. The area of the second forming surface retained on the blank 100 is the second finished surface 420, thereby obtaining a finished product.
[0059] See also Figure 3-Figure 5 The detailed process of processing the plano-concave lens 400 product through the above steps S100-S400 is as follows:
[0060] In the specific process of step S100, taking the plano-concave lens 400 as an example, the first surface and the second surface 102 of the circular blank 100 matching the Φ30 circular window are first polished to form a Φ30 circular window, wherein the first surface is polished as a whole to obtain a full-aperture first forming surface 110 (i.e., the entire end surface on the side where the first surface of the blank 100 is located after processing), and the second surface 102 is polished as a whole to directly meet the finished product requirements. In this way, the first surface and the second surface 102 after processing both meet the finished product requirements, wherein the first forming surface 110 processed from the first surface is required to meet the predetermined finished product quality standard. The predetermined finished product quality standard may be that the polished surface aperture is less than 2 circles.
[0061] In the specific process of step S200, taking the plano-concave lens 400 as an example: a protective sheet of the same diameter as the photosensitive adhesive is used on the first forming surface 110, and the protective sheet completely covers the entire first forming surface 110. The thickness of the protective sheet is 0.5-2 mm. If the protective sheet is thicker, it is milled to a larger size. In addition to using a protective sheet of this thickness to protect the first forming surface 110 that has been processed and formed, an appropriate processing allowance is ensured during the subsequent processing, which can improve the subsequent processing accuracy and efficiency. The adhesive layer is as thin as possible, and the thickness of the adhesive layer is 0.002-0.004 mm, which is conducive to controlling the processing size of the finished product, facilitating size detection during the processing, and can well ensure the size of the finished product.
[0062] In the specific process of step S300, taking the plano-concave lens 400 product as an example: the semi-finished workpiece 300 formed by bonding the protective sheet is subjected to full-aperture processing (i.e., processed together with the protective sheet), and milling, fine grinding, and polishing are performed to form a second forming surface 310 on the first side end face of the semi-finished workpiece 300, and the size is strictly controlled so that the final size of the product meets the predetermined requirements, ensuring that the final size of the product is 0.01mm (+0.01 / 0), (for ease of viewing and understanding, the radius and the arrow height are not drawn in proportion, and the product is cut in half). It should be noted that the final size of the arrow height is 0.01, so during the processing of this step, the operator is required to detect the processing control size so that the processing control size meets the requirements, thereby ensuring that the final size of the product meets the predetermined requirements. During the processing of the second forming surface 310, the processing control size is detected to make the processing more convenient.
[0063] See also Figure 5 and Figure 2 In the specific process of step S400, taking the plano-concave lens 400 as an example, the unprocessed protective sheet is directly removed to obtain the unprocessed first forming surface 110 area, which is the first finished surface 410. The area of the second forming surface retained on the blank 100 of the semi-finished workpiece 300 is the second finished surface 420, thereby obtaining the finished plano-concave lens 400.
[0064] In summary, the present application provides a processing method for an optical component with adjacent different processing surfaces. Compared with the existing traditional methods, when polishing two surfaces that interfere with each other (such as: a lens with a concave arc angle less than about 1° and a platform at the edge, and an optical prism with two plane angles greater than 179°), it is very easy to scratch the adjacent surfaces. The processing method of the present application protects the processed surface by bonding a protective layer of similar material, which will not affect the polishing and may even help to polish the surface to obtain a higher precision. This solution can effectively protect other surfaces except the positive processing surface, especially optical components with two surfaces interfering with each other, and can extend a very small polishing surface to a large surface to facilitate the processing of the polishing surface.
[0065] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
