become an important issue. Generally, the lenses constituting the optical system generally have a spherical lens and an aspherical lens. Most spherical lenses are produced by cold working (e.g., grinding, grinding, etc.) of a glass material, or by cold working a glass molded article obtained by reheating and press forming. On the other hand, the main method for manufacturing an aspherical lens is to pressurize and shape a heated, softened spherical, ellipsoidal or flat glass block (for example, a preform) by a mold having a high-precision forming surface, and mold the mold. The high-precision molding surface shape is transferred onto the preform to form an aspherical lens, that is, an aspherical lens is produced by precision press molding. Here, the preform can be produced by temporarily forming molten glass into a plate-shaped glass and using a cold working method such as cutting, grinding, and grinding.

Moreover, the steps of cleaning and the like can be omitted, so that the productivity of the optical element can be improved. [Embodiment] Hereinafter, the embodiment of the manufacturing apparatus and the manufacturing method of the optical element of the present invention will be described in detail. However, the present invention is not limited to the following embodiments, and can be appropriately modified and implemented within the scope of the object of the present invention. Incidentally, the description of the overlapping description may be omitted as appropriate, but the scope of the present invention is not limited. As shown in the first and second figures, the manufacturing apparatus 100 for manufacturing an optical element from molten glass (hereinafter referred to as a manufacturing apparatus) includes a glass block manufacturing apparatus 400, a precision press forming apparatus 300, a conveying apparatus 700, and a transfer Devices 500 and 600. The glass block manufacturing apparatus 400 forms the molten glass C which flows down through the flow path 200 into the glass block E by a shaping|molding die. (Flow Path) The flow path 200 is connected to a melting furnace (not shown) to drip the molten glass C melted in the melting furnace. A sensor or the like (not shown) is disposed on the flow path 200 so that the molten glass C can be divided into a predetermined volume or a predetermined mass at intervals, and the molten glass C can be controlled at a predetermined time by a predetermined volume or The quality of the 200844058 is dripped. (Glass Block Manufacturing Apparatus) According to the first and second figures, the glass block manufacturing apparatus 4 is, for example, a rotating table 422 and a plurality of forming dies 430, wherein the rotating table 422 is supported by self-rotation. A plurality of molding dies 430 are disposed at concentric positions on the peripheral portion of the turntable 422, and can accommodate the molten glass flowing out from the lower end of the flow path 2 . Specifically, the glass block manufacturing apparatus 400 includes a disk-shaped rotating table 422 that is rotatably supported by the rotating shaft 425 so as to be rotatable, and a rotating shaft 425 that is coupled to a driving source for rotation not shown. The glass block manufacturing apparatus 400 may also be provided with a cooling t setting (not covered) around the rotating shaft 425 as the case may be. The molding die 43 disposed on the rotary table 422 is moved right below the flow path 200 by the rotation of the rotary table 422, so that the molten glass c is dropped from the flow path 200 into the molding die 43. Preferably, the glass block manufacturing apparatus 4 is capable of floating the molten glass on the forming mold. As a form of the floating forming, it is disclosed in Japanese Laid-Open Patent Publication No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. No. Hei. The method. Further, in order to float the molten glass, it is preferable that the molding die uses a matte material to eject the gas from the holes, but it may be non-porous as disclosed in Japanese Laid-Open Patent Publication No. 2003-40632. The material consists of the inverted 200844058 conical shape. Further, as the case may be, as disclosed in Japanese Laid-Open Patent Publication No. 2004-300020, the glazed glass is temporarily taken up by the support (supporting mold) before entering the forming mold. When the molten glass is dropped into the molding die 430 by the schematic path 200, the detection of the molten glass c by a sensor (not shown) or the control according to the preset setting time causes the rotary table 422 to rotate at a fixed angle. Further, the molding die 430 containing the molten glass C moves in accordance with the rotation of the rotary table 422. With the rotation of the rotary table 422, the forming die 430 is moved from the flow path 2, and the lower portion is moved directly below the first transfer device. During this time, the molten glass is formed into a curved body and cooled to become a glass block. Then, when the temperature of the glass block E drops sharply, the guide block also causes problems such as cracks and defects. In this case, it is preferred that the mosquitoes are placed in an arbitrary number of heating means to heat the forming mold. The temperature of the forming mold is rapidly lowered. 8. The heart rate causes the defective ratio of the glass molded article to be less likely to rise. Furthermore, when the rotary table 422 is in a stationary state, (the first transfer device and the second transfer device), in the manufacturing device of the present invention, the transfer device can be used to transfer the glass block or the second element. :: arranging and appropriately arranging transfer between the glass block manufacturing aggregation 400 and the device diagram and the second image transfer device 700 and the precision press forming @, and between the garments 300. 200844058 The situation of the device. Wherein, when the rotary table 422 500 is in a stationary state of the plurality of forming dies, the first transfer means is directly above, and one or a plurality of forming dies 700 are formed from the forming die 43. There is no special way to take out the glass slab and transfer it to the transport, transport, and placement. The side 2 that is held by the robot arm is the glass block (transport device). As shown in the second figure, The transport tray 762 and the loading tray 7 are smashed and smashed. The glass slab E is stored in the transport belt 760, and the tray 762 is smashed and moved to serve as a moving device and a heat insulating device for maintaining the temperature of the tray 762. A concave forming surface 762 & is formed on the surface of the tray 762 so that the number of the concave forming surfaces can be any number. The conveyor belt 760 is placed on the glass making device 4, and the glass is placed. The block E tray 762 is transported to the lower one-step one of the mechanisms of the precision press forming shaker. Therefore, the transport method is not particularly limited, and the case may be a belt type or a drum type. For convenience of explanation, the conveyance of the belt mode is illustrated in the third figure. In this case, the tray 762 is moved by a conveyor belt 760 driven by a motor (not shown): the conveyor belt 760 can be reversed at the end And the structure of the circle, It is a structure that is looped by the inside of the tray 762. The conveyor belt 760 is operated by a computer, such as a photoreceptor (not shown), by a computer, and is operated by a computer. The glass tray E tray is placed along with the operation of the conveyor belt. 762 moves in a fixed order or stops at a mosquito position. As described above, it is preferable that a transport device (not shown) for heating the tray 762 is provided in the transport device 700. The heating device (not shown) It is a device for preheating the glass block E tray 762 carried by the first transfer device 5 (8). The reason for the heating device is that if the tray 762 is cool, the shell q will be slammed from the glass block E. By taking in heat, it is easy to cause adverse effects such as sincerity. Here, the temperature at which the tray is heated may be appropriately changed depending on the properties of the glass block E, etc., preferably at a temperature of 100 C or more and 400 C or less. Preferably, it is heated at a temperature of 11 〇 or more and 380 ° C or less, and is preferably heated at a temperature of 12 〇 or more and 350 ° C or less. Further, preferably, the following uses Insulation device 763 The temperature of the consumer disk 762 is maintained at the top, and the ghost is carried away by the sinking of the ghost. Moreover, the heating device appropriately changes the heat resistance of the glass according to the thermal characteristics of the glass. Depending on the case, the heating device may be omitted. The heating method of the heating device (not shown) may be heating by gas or the like, or heating by electricity. The looseness must satisfy the problem of deformation or the like caused by heating by a heating device (not shown). It is preferable that the conveying device 700 is provided with a heat insulating device 763 for holding the broken block. The reason is that in the process of precision press forming, it is necessary to heat the glass to the glass transition point to a temperature of 14 200844058 degrees. However, if the temperature is excessively decreased, it is necessary to make the precision press forming before = The heating time exceeds the necessary time', which not only makes the precision pressurization cycle insignificantly longer, but also makes the glass pass through the useless heat history and is easy to produce = warpage, deformation, etc., which easily leads to the addition. The yield at the time of press forming is α, and when the glass block is supplied to the precision press forming apparatus 3, the temperature of the glass block after the heat retaining device 763 is preferably adjusted to 50 C or more. Better 疋70 C or more, the best is 1 〇〇. 〇 Above. The heat retention mechanism of the heat retention device 763 is not particularly limited, and may be heated by a fuel such as a gas or the like by heating, similarly to the above-described heating mechanism (not shown). In this manner, the glass block E of the precision press molding is heated by the heating device and the heat insulating device 763, and the temperature of the glass block E is raised as described above, thereby dissipating the surface of the glass block E until the precision press molding. Thus, a spoiler is generated around the glass block E. By this turbulence, foreign matter such as garbage and dust adheres to the surface of the glass block E. As a result, the cleaning step of the glass block E can be omitted, and the optical element can be efficiently manufactured. (Precision Press Forming Apparatus) As shown in FIG. 4, the precision press forming apparatus 3 includes a lower mold 301 that accommodates the glass block E transferred by the second transfer apparatus 600 and serves as a pressurizing time. One part of the mold; the upper mold 302 as a part of the mold for pressurizing the glass block E received on the lower mold 301; and the press machine 303, which is supplied to the lower mold 301 and the upper mold 3〇2 The glass block E is pressurized; and the conveyor belt 3〇4 is placed and moved by the lower mold 3〇1. Further, in order to facilitate the description, only one precision press forming apparatus 300 is described in the fourth drawing, but as shown in FIG. 5, a plurality of press forming apparatuses may be used to form a glass block forming apparatus. The glass block made of 400 is pressurized. The lower mold 301 has a molding surface for accommodating the glass block e and is molded, and can be directly pressed by the upper mold 302 to manufacture an optical element. A mold release film (not shown) for suppressing damage on the molding surfaces of the lower mold 3〇1 and the upper mold 3〇2 is provided on the molding surfaces of the lower mold 3〇1 and the upper mold 302. Here, as the material of the lower mold 301 and the upper mold 3〇2, a cemented carbide such as tungsten carbide may be used, and any material such as tantalum carbide, crystallized glass or stainless steel may be used. As a release film, a carbon-based film such as ruthenium, iridium, epoch-type film, diamond-Uke carbon, or titanium (titanium nitride) or

The lower mold 301 and/or the upper mold 302 may be heated by a heating means (not shown) as needed, so that the glass block E is heated on the one hand and pressurized. Further, the mold may be heated in advance before the glass block E is placed in the lower mold 3〇1. The press machine 303 presses the lower mold 301 and/or the upper mold 3〇2 to pressurize the glass block E between the lower mold 3〇1 and the upper mold 302. The pressurization method is not particularly limited, and it can be pressurized by a well-known pressurization method. The time, pressure, and heat history at the time of pressurization can be appropriately changed depending on the shape of the optical element to be obtained, the material of the glass block E, and the like.

At this time, it is preferable to adjust at least the glass block and the c, and at least to adjust c to at least a/b. Scope = Here, if (a), at a/b, it is easy to produce a dough piece that exceeds the processing capacity of a precision press molding machine, and (4) an important factor that tends to reduce the material yield. In addition, in this specification, "The average % required for precision press forming, and the interval β is a (seconds per piece)" means that the precision is indicated when the forming device is connected to the glass block manufacturing device.
