目耵光學設備的鏡片多半為以玻璃材質製造，而製造 玻璃鏡片的主要方式之一為以熱壓塑型模仁於熱塑型玻璃 材料升溫軟化後加壓，以形成玻璃鏡片，因此熱壓塑型模 仁上對玻璃施壓的一面必須預先經過刀具車削或研磨創成 -理想的軸對稱鏡片轉寫面，所謂軸對稱係該鏡片轉寫面 由俯視觀之為圓形，最後將熱壓塑型模仁的軸對稱鏡片轉 寫面透過施Μ方式轉寫到玻璃材料上。 目前創成熱遷塑型模仁的鏡片轉寫面方式多半以CNC (Computer numericaI contr〇1)加工機來車削或研磨’因 此刀具對熱壓塑型模仁的加工路徑可利用方程式並透過電 C/ 腦來進行控制，該方程式如下：Most of the lenses that witness the optical equipment are made of glass. One of the main ways to manufacture glass lenses is to pressurize and heat the thermoplastic glass material after hot pressing to form a glass lens. The side of the molded mold that presses the glass must be pre-cut by the tool turning or grinding - the ideal axisymmetric lens transfer surface, the so-called axisymmetric system, the lens transfer surface is rounded from a top view, and finally hot pressed The axisymmetric lens transfer surface of the molded mold core is transferred to the glass material by means of application. At present, most of the lens transfer surfaces of the heat-transformed mold cores are turned or ground by CNC (Computer numericaI contr〇1) processing machine. Therefore, the machining path of the tool for the hot-pressed mold core can be solved by the equation and transmitted through the electricity C. / Brain to control, the equation is as follows:

The method of manufacturing the mold of the heart is as shown in the first figure, when creating the axis-symmetric lens transfer surface (1〇1) on the mold core (1 〇〇), due to optical design limitations, in the silk 璧 + ηπ , the glaze-to-private lens transfer surface (101) and the mold core (1, there is no smooth connection between the shell plane (1 0 2), it is easy to make j to the money sheet transfer h1q1) and the material surface (iq2), Brother and Boundary (1 0 3 ) 'The sharp junction (i 〇3 ) shows a sharp angle along the section passing through the center of the lens transfer surface, and is pressed to heat-pressed glass (UG) when heated. At the same time, the glass flows through the sharp junction 3) and /, the sharp edge of the father produces friction, which easily causes cracks, flow lines, etc. at the junction, which reduces the molding quality, precision and production yield of the lens. Also on the surface of the mold,? A layer of protective film will be applied to increase the life of the mold. Japanese Patent Application No. 88437 discloses that a mold core for manufacturing a lens has an arc-shaped interface formed between the axis-symmetric lens transfer surface and the top plane, and the curved interface is transposed along a lens. The cross-section of the center of the face is connected to the outer contour of the transfer surface and has a fixed radius of curvature. The fixed radius of curvature is preferably in the range of 〇2 mm or more, so that the top plane and the axisymmetric lens transfer surface are smoothly connected. In order to avoid the sharp junction, the frictional force of the glass flowing through the sharp junction can be reduced when the glass is hot-pressed, so that the precision and yield of the molded glass are improved. However, when manufacturing the mold core, it is necessary to separately combine the two axes of processing for the axisymmetric mirror 5 200804204 sheet transfer surface and the interface with fixed curvature, so that the machining program is programmed and processed. It must be divided into two paragraphs. Since the processing program has two sections, the processing machine equipment currently used on the market cannot support two different processing programs to correct at the same time. Therefore, when the machining program is corrected, each segment needs to be corrected separately, resulting in a combination of the molds. Accuracy is difficult to control effectively and improve 'It is also easy to increase the processing time due to too many correction times, greatly reducing the mold yield. In addition, the interface is an additional radius of curvature. This part cannot be effectively connected to the optical characteristics of the axisymmetric transfer surface. Although it is outside the optical effective path, it is easy to cause stray light interference and reduce the image quality. The optical glass disclosed in Japanese Laid-Open Patent Publication No. Hei. No. 2,249,812, the optical glass forming apparatus and the manufacturing method thereof, are in the forming design, and the outer diameter of the axis is symmetrically transferred to the outer surface. The interface reduces the angle of intersection of the axisymmetric transfer surface with the top plane. Therefore, the __ plus ^ symmetry transfer surface has a non-fixed curvature, which can be improved by the interference of stray light ‘and at the same time take into account the Japanese public (4) 1 188 437. However, the design of the two-section surface is still unfavorable in processing and correction: the sex has not been effectively improved. The interface is limited to be lighter and thinner. The optical glass technology of the above-mentioned conventional optical glass technology has an effective diameter, and it is easy to increase the outer diameter of the molded lens, and the future design concept. [Summary of the Invention] There are sharp corners, two-stage addition is not easy, or in addition to the cause of the invention, the present invention eliminates sharp corners according to the above-mentioned existing molds, and two different program corrections are made. 200804204 Adding interface is difficult to design with original optical Combining and increasing the shortcomings of the outer lens of the molded lens, improving the deficiency and lack thereof, and inventing a hot compression molding device for manufacturing the axisymmetric glass lens, the method for manufacturing the hot compression molding device, the axisymmetric glass lens and the preparation method thereof . In order to achieve the above object, the hot compression molding device for manufacturing the axisymmetric thermoformed glass lens comprises an upper mold core and a lower mold core, and at least one mold core of the mold core comprises: (1) an axisymmetric a lens transfer surface formed on the mold and having an axisymmetric curved surface; (2) a critical surface: formed on the mold, surrounding and smoothly connecting the axisymmetric lens transfer surface, and It is a part of the axisymmetric arc surface; (3) a plane is formed on the mold core, and is wound and smoothly connected to the critical surface. Among them, the radius of curvature of the critical surface is absolutely constant from the direction of the axis-symmetric lens transfer surface to the plane, which is not a fixed Ί ’ and the intersection angle of the critical surface and the plane gradually approaches zero. By the above technical means, the critical surface of the core can smoothly connect the lens to the plane and the plane and is not limited by whether it is an effective diameter or not. Dream This glass material can flow smoothly through the critical surface. 4 庠p夂 You cut, no hinder, avoid processing ‘degree reduction and improve lens production yield.

All the mold cores can be carbides, and all modules -# & 1 ^ Nitride or tantalum sintered body, (4) The surface of the kernel can be obtained by physical gas phase ^ / ί: chemical emulsion phase deposition method and 7 200804204 ion sputtering method, etc., chain, silver, red, lack of " /, adult shell For gold, Syrian, silver, hungry, alloy or alloy combination, T-like drill: find: metal elements, these metal elements on the face clock - layer or multilayer::: Tao coffee, diamonds, etc. in the mold The thermal method of the k-axis symmetrical glass lens is formed by one-time processing and one-time processing of the surface of the manufacturing side (1)-axisymmetric lens of the # y main ,, and there are: 犹 MH , formed in the mold The upper side, and the pair of axes, the team, and the (2)-critical plane are formed in the flat connection of the axisymmetric lens transfer surface, and are axisymmetric curved surfaces:: the surface of the mold is 'circumscribed and smoothed The direction connecting the = face is constantly changing. The t-transformation surface is flattened to a flat, and the constant angle between the fixed constant and the plane is gradually Close to zero. L-interface section - an axisymmetric glass lens having at least one side comprising a bounding surface: formed on the lens and having an axisymmetric arcuate surface; said sheeting + face '(iv) being 'circumscribed on the lens and Smoothly connecting the pair of shafts formed on the lens, surrounding and smoothly connecting the critical surface? The absolute value of the radius of curvature of the surface is from the axis-to-plane variation of the axisymmetric lens surface, not a constant constant value, and a critical surface The cut surface and the flat gradually approach zero. 1 and angular" can be coated on the surface of the axisymmetric glass lens by physical vapor deposition, chemical wide-phase deposition and ion sputtering, plating a layer of external light, anti-infrared light, filtering specific visible light and Light with increased light transmission rate 8 200804204 Filming. The symmetry of the glass lens is made by a symmetrical glass lens. The glass is made of a hot-pressed plastic device to form an axisymmetric shape. At least the mold core containing - the upper mold and the lower mold = mold 1 contains - (4) said lens transfer surface, - critical ^ and #: two = symmetric lens transfer surface formed on the mold, And a thin arc surface of -f, the critical surface is formed on the mold core, surround and smooth = the axisymmetric lens transfer surface, and the plane of the axisymmetric arc surface is formed on the mold core, Surrounding and smoothly connecting the critical surface is formed by transferring the shape, the critical surface and the plane of the heat-shaping device to the glass material, respectively, to form a surface of the lens, Face and - plane. : The curve of the critical surface of the glass lens The absolute value of the radius changes from the direction of the axisymmetric lens to the plane, and the angle of intersection between the plane and the plane of a fixed interface gradually approaches zero. m [Embodiment] This section mainly improves the conventional technology design. Disadvantages, (the factory avoids the sharp boundary when the glass is molded; (2) reduces the shape of the mold, creates the time and pattern connection processing error and programming, corrects the time to correct the monthly and corrective validity; (3) increases the criticality The optical properties of the surface are set to the elasticity of the fish. ^ ϋ ϋ The method for manufacturing the axisymmetric glass lens of the present invention, as in the second drawing, uses a hot compression molding device at a temperature of 300 to 7 (10) degrees Celsius.

The surface of the lens of the axisymmetric lens (3 a) can be plated with one or more optical films (4 5) by physical vapor deposition, such as chemical vapor deposition and ion sputtering. The film (45) may be an anti-ultraviolet film, an anti-infrared film, a specific visible light film, and a light transmittance film. In addition, as shown in the cross-sectional view of another embodiment of the axisymmetric glass lens shown in the figure, the axisymmetric glass lens (30b) can also be right-handed and πa#^r, π, ^, has an early axis forming the axisymmetric lens surface (40), critical surface (4 work) and flat r. (4 2 ) as shown in the third B diagram, the axisymmetric processing of the axis is used to manufacture the axisymmetric glass mirror. - Schematic diagram of the cross-section of the embodiment, when the axisymmetric lens transfer surface (20a) of the upper mold core (worker a) is a convex surface, and the critical surface (2... is a concave surface, an axis such as the third c diagram is produced. The symmetrical glass lens (3 〇c ) is a concave lens. The axisymmetric lens surface (4 〇 c ) is a concave surface and the critical surface ( 41 c ) is a convex surface. The surface of all the axially symmetric hot-molded glass lenses can be plated or : an optical film such as a layer of an anti-ultraviolet film, an anti-infrared film, a transition-specific visible film, and a light-transmitting film. / By the above technical means and embodiments, the present invention has the following characteristics as compared with the prior art features Several features: 1. The critical surface of the mold can smoothly connect the axisymmetric lens transfer surface and plane Thereby, the glass material can smoothly flow through the critical surface without hindrance, avoiding the reduction of processing precision and improving the production yield. 2 · The invention improves the equation constant of the axisymmetric figure, so that the axisymmetric diagram of the mold core rises "including the axis Symmetrical lens transfer surface and critical surface can be 14 200804204 Directly smoothing the connection plane 'In addition, the formation of the image is only required to be under-processed, and the correction of the axisymmetric figure can be divided into multiple segments at one time. It is avoided that the current processing machine cannot support the multi-segment program and the function of correcting at the same time is insufficient. Therefore, when processing the axisymmetric figure of the mold core, the design time and processing error of adding the program of the axisymmetric transfer surface and the critical surface can be reduced. This effectively improves the correction accuracy and yield of the mold, and greatly shortens the processing time of the virtual correction. /, r < 3. The critical surface of the invention is not limited by the optical effective diameter of the axisymmetric pattern, and can be reduced to the effective technique plus the interface. The disadvantage of increasing the outer diameter of the lens is more in line with the design concept of thin, light and short in the future, and the design flexibility is increased."
