Description

  The present invention relates to a system for manufacturing spectacle lenses.

As a spectacle lens manufacturing apparatus, one described in Patent Document 1 below is known.
In this manufacturing apparatus, NC (Numerical Control, numerical control) processing is performed on the object side surface and the eyeball side surface of a semi-finished lens having a circular outer shape to obtain a prescription value including a spherical power (S frequency). A suitable spectacle lens is manufactured. The outer shape of the manufactured spectacle lens is processed into a lens shape such as a drop shape smaller than the circular outer shape so as to be attached to the spectacle frame at a spectacle store or the like.
When a spectacle lens is inserted into a spectacle frame to produce spectacles, the shape (rim) of the spectacle frame to which the lens is fitted varies, and the optical center of the spectacle lens and the pupil position of the wearer are used for optical functions. Since the eye point needs to be arranged at a predetermined position of the spectacle lens when the (eye point) matches or the prism is present, the eye point varies from wearer to wearer. Thus, a lens having a circular outer shape (round lens) is processed into a target lens shape.

In such a spectacle lens manufacturing apparatus, spectacle lenses suitable for the prescription value are efficiently manufactured by processing the semi-finished lens with a small amount of stock.
However, since the spectacle lens is manufactured so that all of the base material portion in the circular outer shape is the same spectacle lens material, it takes time and effort to process the outer shape of the lens to be put into the spectacle frame. The part cut from the circle during processing is wasted.
Therefore, using a three-dimensional printer for an optical structure described in Patent Document 2 below, a spectacle lens whose outer shape is a target lens shape and the object-side surface shape and the eyeball-side surface shape conform to the prescription value is converted into ultraviolet rays (UV). It is conceivable that the ink droplets are formed by deposition of ink droplets that are cured by the above-described method.

Japanese Patent Laid-Open No. 10-175149 Special table 2014-502931 gazette

However, since the spectacle lens manufactured by the printer of Patent Document 2 is based on the accumulation of ink droplets, it is not actually a lens spectacle lens having the performance required at present.
That is, ink having a practical cost that is cured by UV has sufficient transparency and transmittance (optical performance) as a spectacle lens, or strength, hardness, durability, etc. (physical performance) after curing. Almost no. In addition, since the ink droplets ejected at present are not so fine and the object-side surface and the eyeball-side surface after curing are rough, the surface cannot be used as a spectacle lens unless these surfaces are polished. There are few inks that can withstand sufficient processing while maintaining various performances after curing.
Moreover, since the spectacle lens of patent document 2 becomes a target lens shape without becoming a round lens like the thing of patent document 1, the existing installation which makes a round lens object cannot be used as it is. Examples of such existing equipment include a laboratory (laboratory) processing apparatus, a secondary processing apparatus, and an inspection apparatus.

Yes.
Hereinafter, for convenience of explanation, when the spectacle lens G is erected as in normal wearing, the horizontal direction is the X-axis direction, the vertical direction is the Y-axis direction, and the direction perpendicular to the XY plane (the lens wall) The thickness direction) is taken as the Z-axis direction. In the X-axis direction, the right direction is the positive direction when standing on the object side of the spectacle lens G, and the right direction for the wearer is the negative direction of the X-axis. Further, in the Y-axis direction, the upward direction standing on the object side of the spectacle lens G is a positive direction (the same applies to the wearer), and the wearer standing on the object side of the spectacle lens G in the Z-axis direction. The direction to (the direction from the object side to the eyeball side) is the positive direction. The various axes and how to take them in the positive direction may be changed as appropriate.
In such a case, the finished surface side mold 21 is along the XY plane, and the surface on the positive side of the Z axis is the finished surface defining surface 21a.

The three-dimensional printer 11 cures a liquid resin that is cured by ultraviolet rays (UV) by UV irradiation, and forms a processed surface side mold 31 (a side peripheral mold, FIG. 3) having a shape based on the processed surface side mold shape data 30. , See FIG. 4B). The processing surface side mold shape data 30 is created by the server 2 with reference to the prescription data 4, the contour shape data 32, and the edge shape type data 33. The contour shape data 32 represents the contour (side circumferential shape) of the eyeglass spectacle lens G, and the edge shape type data 33 represents the type of edge shape which is the cross-sectional shape of the side circumferential surface of the eyeglass lens G. (Edge shape data).
The processed surface side mold 31 is disposed on the finished surface defining surface 21 a side of the finished surface side mold 21, and in addition to a part of the side periphery of the semifinished lens M or the spectacle lens G, the semifinished lens M This defines the entire work surface WP.
The processed surface side mold 31 has a disk shape having a recessed portion 31a at the center of the surface on the finished surface side mold 21 side (surface on the object side), and the surface on the object side that is outside the recessed portion 31a is , Along the finished surface defining surface 21a.
Further, the bottom surface of the recess 31a (the object-side surface in the recess 31a) serves as a processing surface defining surface 31b that defines the processing surface WP of the semi-finished lens M.
Further, the peripheral surface of the recess 31a (the standing surface between the bottom surface in the recess 31a and the surface outside the recess 31a), that is, the inner surface of the mold 31 on the surface to be processed (inward in the radial direction and intersects in the radial direction). Surface) is a side periphery defining surface 31c that defines part of the side periphery of the semi-finished lens M or the spectacle lens G. The side periphery defining surface 31c may have a groove-like recess that is recessed further outward in the radial direction from the periphery thereof. There may be a mounting portion defining surface 31d that defines a bevel projecting in the direction. The attachment portion defining surface 31d may be omitted, may be formed around the circumference, may be formed at a part of the circumference, or may be further formed around the side circumference defining surface 31c. It may protrude radially outward (corresponding to the case where the attachment portion is a groove on the side periphery).
In addition, the processed surface side mold 31 has a filling port J that is a passage extending in the radial direction from a part of the peripheral surface of the recess 31 a to the peripheral surface of the processed surface side mold 31. The side circumference of the spectacle lens G excluding the connection portion of the filling port J is defined by the side circumference defining surface 31c. The filling port J may be formed such that the shape thereof is included in the processed-surface-side mold shape data 30 so that the resin is not disposed in the portion of the filling port J by the three-dimensional printer 11. 11 or another device or an independent device has a drilling means such as a drill so that the filling port J is formed by the drilling means after the formation of the processed surface side mold 31 without the filling port J. Also good. Further, the filling port J may be directed in the direction along the X axis or in another direction in place of the direction along the Y axis in the semifinished lens M.
The processed surface side mold 31 may define the entire side periphery of the semifinished lens M or the spectacle lens G, or may define a part of the processed surface WP of the semifinished lens M. .

The three-dimensional printer 11 that forms the processing surface side mold 31 includes a liquid fixed amount discharge means 34, a UV irradiation means 35 as a curing means, for example, a UV light emitting LED, a connection means 36, and a processing surface side mold shape data. A storage means 37 for storing various data such as 30 and programs, and a control means 38 for controlling them are provided.
The connecting means 36 is communicably connected to the connecting means 7 of the server 2. That is, the symbols “A” in FIGS. 1 and 2 are connected to each other, and so on.
In the liquid fixed amount discharge means 34, the liquid resin quantified based on the processed surface side mold shape data 30 is discharged while being irradiated with UV by the UV irradiation means 35, and the cured liquid resin deposit is formed on the processed surface. It becomes the shape according to the side mold shape data 30, and becomes the processed surface side mold 31.
The three-dimensional printer 11 may be one that discharges a liquid resin that is cured by heat. In short, liquid (ink) is sequentially discharged and deposited in a fixed amount by the liquid fixed discharge means 34 based on various shape data. And may be cured by curing means (UV irradiation means 35 or heating means). The curing of the liquid by the curing means may be performed at the time of discharge, at the time of deposition (at the time of adhesion), or after a predetermined time has elapsed from the time of ejection (deposition). The curing unit may be arranged in a device different from the three-dimensional printer 11 (fluid resin discharging unit), or may be configured as a separate and independent device. Further, the three-dimensional printer 11 may be other than the one that laminates and hardens the liquid as long as it is a layered modeling (layered modeling means). For example, a metal powder (solid) spread in layers on a table. ) Is irradiated with a laser based on the shape data to melt and solidify only the irradiated portion (for example, with a thickness of about several tens of microns), and further, a metal powder is laid in layers on the layer and irradiated with the laser in the same manner. A three-dimensional metal additive manufacturing apparatus that obtains a metal structure (work surface side mold 31) by repeating these (for example, several thousand times) may be used. Further, the three-dimensional printer 11 may be a combination of a liquid that is laminated and cured and a three-dimensional metal additive manufacturing apparatus. In addition, the liquid resin may be a highly viscous resin or the like. In short, a fluid resin that is a fluid resin may be used.
The processed surface side mold shape data 30 preferably represents a three-dimensional shape, but may represent a two-dimensional shape. In the latter case, the vertical and horizontal shapes are assumed to represent vertical and horizontal shapes. The thickness perpendicular to may have a predetermined distribution such as a constant thickness.

For example, the processed surface side mold 31 is formed by laminating from the bottom to the top so that the recessed portion 31a (object side) appears on the 3D printer 11, and the finished surface side selected by the finished surface side mold selecting device 10 In combination with the mold 21, a mold 42 (see FIGS. 3 and 4) for the semi-finished lens M is formed. In the mold 42, the processed surface side mold 31 is arranged so that the radially outer surface of the recessed portion 31 a contacts the finished surface defining surface 21 a of the finished surface side mold 21.
In addition, at least one of the processing surface side mold 31 and the mold 42 may be created for each predetermined shape in advance. In this case, the processing surface side mold shape data 30 is formed in advance. The type may be indicated, and a shape according to the type may be selected. Alternatively, a mold fixing means such as an adhesive tape for fixing the finished surface side mold 21 and the processed surface side mold 31 in the mold 42 so as not to shift and an adhesive that can be easily peeled off may be provided. The finished surface side mold selecting device 10 or the three-dimensional printer 11 may be attached to the mold 42 by a mold fixing means attaching device provided independently or may be attached manually. Further, the processed surface side mold 31 may be formed so as to have viscosity or adhesiveness (with a material exhibiting viscosity or adhesiveness after curing) and may be fixed to the finished surface side mold 21. The side mold 21 may have viscosity and adhesiveness. Further, the mold 42 may include portions other than the finished surface side mold 21 and the processed surface side mold 31. For example, the processed surface side mold 31 does not include the processed surface defining surface 31b, and the side peripheral defining surface 31c. When the donut shape is provided, a film for closing the surface on the Z-axis positive side of the doughnut-shaped workpiece surface side mold 31 may be included. In this case, the surface on the negative side of the Z-axis of the film is a work surface defining surface 31b. Further, the portion corresponding to the film in this case may be separately formed by the three-dimensional printer 11 or a plate-like body previously formed in a plate shape may be used. A plurality of types of plate bodies may be prepared according to the size, the shape of the work surface defining surface 31b, and the like, and may be selected based on the work surface side mold shape data 30 and the plate body type data.

The lens curing device 12 is a spectacle lens in which a portion (cavity) surrounded by the finished surface side mold 21 and the processed surface side mold 31 in the mold 42 is filled with a thermosetting resin material as a spectacle lens material from a filling port J. Heat is applied to the resin material filling means 43 as the material filling means and the mold 42 filled with the thermosetting resin material in a predetermined manner (temperature, time, etc.) according to the type of the resin material. A lens curing means 44 for curing the curable resin material and a semi-finished lens M (see FIGS. 4B and 5A) formed by curing the thermosetting resin material in the mold 42 are covered. A partly releasing means 45 for separating from the finished surface side mold 21 with the processed surface side mold 31 attached, a connecting means 46 communicably connected to the connecting means 7 of the server 2; Storage means 48 for storing various data and programs such's type data 47, and a control unit 49 for controlling these. The lens type data 47 indicates the type of the spectacle lens G that satisfies the prescription data 4, and includes the type of spectacle lens material, the presence or absence of dyeing (color), HC film, and optical multilayer film, and the type in the presence.
The resin material filling unit 43 selects and fills the type of spectacle lens material indicated by the lens type data 47 in the storage unit 48. The resin material filling means 43 may always fill a predetermined spectacle lens material without referring to the lens type data 47.
The lens curing means 44 is, for example, a chamber provided with a heater, and the partial release means 45 is, for example, a robot hand. However, releasing the finished surface side mold 21 (partial release) may be performed manually. . It should be noted that another lens material such as a UV curable resin material may be used instead of the thermosetting resin material, and another plastic such as a UV curable resin may be used instead of the thermosetting resin.

The lab processing apparatus 13 stores a storage means 53 for storing various data such as construction surface shape data 50 and programs, and an eyeball side surface (processing surface WP) of the semi-finished lens M with the processing surface side mold 31. It has the grinding | polishing means 54 to grind | polish, the connection means 56 connected so that communication with the connection means 7 of the server 2 is possible, and the control means 58 which controls these.
The construction surface shape data 50 is created from the prescription data 4 by the server 2.
The polishing means 54 is, for example, an NC-controlled grindstone, a chuck and a block piece 59 (see FIG. 5A), and the surface on the Z-axis positive side of the semi-finished lens M with the processed surface side mold 31 (processed) Surface WP) is polished so as to have a shape based on construction surface shape data 51. That is, as shown in FIG. 5 (a), in order to properly hold the semi-finished lens M with the work surface side mold 31 on the chuck (at a position aligned with the grindstone at the time of polishing), A block piece 59 having a contact surface 59a that matches the curve of the surface of the semi-finished lens M with the work surface side mold 31 is placed at an appropriate position (the bonding surface and the center of the semi-finished lens M coincide with each other). Adhere to the position where Then, the semi-finished lens M with the processed surface side mold 31 is held by the chuck via the block piece 59, and the surface on the Z axis positive side is polished as shown in FIGS. 5 (b) and 5 (c).
By this polishing, the semi-finished lens M having the processing surface WP as the Z-axis positive side surface becomes the pre-finishing spectacle lens G ′ having the construction surface W2 as the Z-axis positive side surface, and the processing surface side mold 31 is The ring-shaped mold 31 ′ surrounding the side periphery of the pre-finishing spectacle lens G ′. Since the construction surface W2 is created by polishing, it is optically accurate. The ring-shaped mold 31 ′ only needs to surround the side periphery of the pre-finishing spectacle lens G ′, and the surface on the Z-axis positive side of the processed surface-side mold 31 is constructed based on the construction surface shape data 51. You may grind | polish by the arbitrary extension surface of the surface W2. The construction surface shape data 51 only needs to include data relating to the construction surface W2, and may not include data relating to the surface on the Z axis positive side of the workpiece surface side mold 31. The construction surface shape data 50 may be a set of Z-axis coordinate values z indicating the polishing depth or the thickness of the lens G ′ before finishing at each XY coordinate value (x, y) at predetermined intervals, or the center. It may be a curve value indicating a curve from a predetermined point such as.
The pre-finishing spectacle lens G ′ with the ring-shaped mold 31 ′ is also referred to as a round lens body 51 hereinafter.

  The round lens body 51 can be held without touching the pre-finishing spectacle lens G ′ by holding the ring-shaped mold 31 ′ in the subsequent processes and the conveyance between the processes. Even if 'is a lens shape or a shape close to this, and the outer shape of the pre-finishing spectacle lens G' is not round, it can be directly put into a target device for a lens having a round outer shape (round lens). Even if the diameter of the round lens is, for example, 50 mm (millimeter), 65 mm, 70 mm, 75 mm, or 80 mm, the outer shape (side circumference) of the ring-shaped mold 31 ′ is arbitrarily shaped by the three-dimensional printer 11. Since it can be formed, it is possible to meet such a request for the diameter by forming the outer shape of the ring-shaped mold 31 ′ so as to be the diameter.

The staining device 14 includes a storage unit 60 that stores various data such as lens type data 47 and a program, a staining unit 62 that stains the round lens body 51 (pre-finishing spectacle lens G ′), and a connection unit 7 of the server 2. Connecting means 64 connected so as to be communicable with each other, and control means 66 for controlling them.
The dyeing means 62 is, for example, a dye solution tank, a jig 68 (see FIG. 6) for holding the round lens body 51, and a steel wire reel with a hook. The jig 68 is suspended by a hook, and the steel wire feed amount (hook) The round lens body 51 is immersed in the staining liquid tank in a predetermined manner (a predetermined time, a predetermined number of times, etc.). The dyeing unit 62 selects a dye bath (color type or the like) corresponding to the lens type data 47 in the storage unit 60. The dyeing liquid may be a dye liquid or a pigment dispersion liquid (coloring liquid). Further, the attachment of the round lens body 51 to the jig 68, the attachment of the jig 68 to the hook, the adjustment of the feeding amount of the steel wire, the selection of the dye solution tank, etc. may be performed manually. The same dyeing may always be performed without referring to the lens type data 47. Instead of the lens type data 47, dedicated data for designating the type of staining may be used.
The jig 68 is an aggregate of a plurality of steel wires bent into a rhombus shape extended on two sides as a whole, and a collar portion 68a for gripping the side periphery of the round lens body 51 disposed at both ends, A ring-shaped spring portion 68b formed in the upper portion (intermediate portion) and a square-shaped arm portion 68c extending between the spring portion 68b and the flange portion 68a are provided. The flange portion 68a at each end protrudes forward and backward so as to intersect with the arm portion 68c, and the jig 68 can hold the two round lens bodies 51 forward and backward. The pair of front collars 68a receives the urging force of the spring part 68b as a torsion spring through the arm part 68c so as to sandwich the round lens body 51, and the pair of rear collars 68a similarly. The round lens body 51 is sandwiched. The spring portion 68b receives the hook described above. When the distance between the pair of flanges 68a is an existing one, it is set to be equal to or slightly smaller than the diameter of the conventional round lens before processing the target lens shape. Note that the number of round lens bodies 51 that can be held by the jig 68 (the number of flanges 68a) and the shape or material of the jig 68 can be variously changed.
In addition, since the ring-shaped mold 31 ′ is present, staining of the side periphery of the pre-finishing spectacle lens G ′ is hindered, but if the finished surface W1 and the construction surface W2 of the pre-finishing spectacle lens G ′ are dyed. It is sufficient and there is no problem even if the side periphery is not stained. Further, since the ring-shaped mold 31 ′ is finally removed, there is no problem even if it is dyed.

In the spin coater, the HC film forming unit 72 corresponds to the lens type data 47 with the HC film formation target surface facing upward. The liquid is dropped and the round lens body 51 is rotated to spread the HC liquid over the surface on which the HC film is to be formed (spin coating method). The HC film is formed by putting the colander 78 in a dryer and heating it at a predetermined temperature higher than room temperature. Note that the same HC film may always be formed without referring to the lens type data 47. Instead of the lens type data 47, dedicated data for specifying the type of the HC film may be used. Further, the HC liquid may be applied by a method other than the spin coating method (dip method by dipping or the like).
The receiving part 78a of the colander 78 is formed by a pair of support bodies 78b that support the left and right when the round lens body 51 stands. The monkey 78 may accept one or more round lens bodies 51. In addition, selection of HC liquid or dripping of HC liquid on the round lens body 51, rotation of the round lens body 51, setting of the round lens body 51 to the colander 78, introduction into the dryer, etc. are performed manually. May be.
Since the ring-shaped mold 31 ′ is present, the formation of the HC film on the side periphery of the pre-finishing spectacle lens G ′ is hindered. It is sufficient if the HC film is formed, and there is no problem even if the HC film is not formed on the side periphery. Further, since the ring-shaped mold 31 ′ is finally removed, there is no problem even if an HC film is provided.

This is a vapor deposition apparatus having a vapor deposition source action means (electron beam irradiation unit) for flying, and the vapor deposited material is vapor deposited on the surface of the round lens body 51 in the lens holder 87 to form one layer in the optical multilayer film. Another vapor deposition material is similarly vapor deposited to form another layer in the optical multilayer film. The thickness of each layer is controlled by the deposition time of each layer, and the order of the materials of the layers in the optical multilayer film is controlled by the order in which the various deposition materials are skipped. The type (configuration) of the optical multilayer film formed on the round lens body 51 is determined according to the lens type data 47. The same optical multilayer film may always be formed without referring to the lens type data 47. Instead of the lens type data 47, dedicated data for designating the type of the optical multilayer film may be used. The optical multilayer film may be an antireflection film or an antistatic film, or a filter that cuts the light by increasing the reflectance of light in a predetermined wavelength region such as blue light. It may be a film, a waterproof film, an antifouling film, a polarizing film, a light shielding film, a colored film, or a combination thereof. The optical multilayer film may be formed on either one side or both sides. Further, the vapor deposition means 82 may be a sputtering apparatus in which an optical multilayer film is formed by sputtering. In addition, a single layer film may be formed.
The lens holder 87 is formed by opening a plurality of lens holding holes 87b in an umbrella-shaped holder main body 87a, and the lens holding holes 87b in the existing lens holder 87 are circular so as to receive a round lens. Is formed. The lens holder 87 may receive one or more round lens bodies 51. Further, various operations of the vapor deposition apparatus, that is, setting of the round lens body 51 to the lens holder 87, insertion of the lens holder 87 into the vacuum chamber, and the like may be performed manually.
Although the ring-shaped mold 31 ′ is present, the formation of the optical multilayer film on the side periphery of the pre-finishing spectacle lens G ′ is hindered. It is sufficient if the optical multilayer film is formed on the side, and there is no problem even if the optical multilayer film is not formed on the periphery. Further, since the ring-shaped mold 31 ′ is finally removed, there is no problem even if an optical multilayer film is provided.

Existing chucks for inspection means are premised on holding a round lens, and there are some that cannot be held in a state where automatic inspection can be performed with a target lens shape or a shape close thereto. Even with such a chuck, the round lens body 51 can be held.
Although the ring-shaped mold 31 ′ is present in the round lens body 51, the inspection can be performed if the inspection area is limited to the pre-finishing spectacle lens G ′ or the ring-shaped mold 31 ′ is a transparent body. .

The finishing device 18 separates the ring-shaped mold 31 ′ from the storage unit 100 that stores various data and programs such as the contour shape data 32 and the edge shape type data 33, and the round lens body 51, and the pre-finishing spectacle lens G.

The input means 116 accepts input of the prescription data 4, the edge shape type data 33, and the lens type data 47 by its operation, and the connection means 119 is set. To the terminal 3.
The prescription data 4 is, for example, S power, astigmatism power (C power), astigmatism axis, addition power, prism, edge thickness, and interpupillary distance. In addition, although it is preferable that the prescription data 4 is right and left separately, the right and left common thing or a single thing can be used suitably.
If the edge shape type data 33 has a bevel shape T (see FIG. 11 (a)) in which the cross-sectional shape (edge shape) of the side periphery of the spectacle lens G protrudes in a Λ shape (triangle), the protrusion height thereof. If it has T-1, T-2, etc. according to the distance from the front peripheral edge of the sheath and the groove shape K (refer to FIG. 11 (b)) having a U-shaped cross section, its depth or deepest K-1, K-2, etc., depending on the distance from the front edge of the part, and H-1, H-2, etc. if the cross-sectional shape is flat (flat). For example, if the edge shape type data 33 is T-1, the edge shape type data 33 represents a bevel shape having a protrusion height of 0.7 mm and having a vertex at a position having a horizontal distance of 1.0 mm from the front surface periphery. The type data 33 represents the shape of a groove having a predetermined width having a depth of 0.6 mm and a deepest portion at a position having a horizontal distance of 1.0 mm from the peripheral edge of the front surface if K-1 is K-1.

The lens type data 47 indicates the type of eyeglass lens material, the presence / absence of dyeing (color), HC film, and optical multilayer film, and the type in the presence. Part or all of the lens type data 47 may be included in the prescription data 4. Part or all of the prescription data 4 and the lens type data 47 may be omitted, included in other data, or handled as separate data.

The contour shape input means 118 accepts input of contour shape data 32 representing the contour of the eyeglass lens G. The contour shape data 32 is transmitted to the terminal 3 via the connection unit 120 based on control by a control unit (not shown) of the contour shape input unit 118.
The contour shape input unit 118 is, for example, a spectacle frame tracer that converts left and right rim inner peripheral shapes of the spectacle frame F into data as contour shape data 32 by scanning the probe. Since the spectacle lens G is attached to the rim of the spectacle frame F, the spectacle lens G is formed into a target lens shape corresponding to the rim shape (rim inner peripheral shape). The contour shape data 32 is a set of XY coordinate values of a predetermined number of coordinate acquisition points (for example, 100 points) with respect to a predetermined origin regarding the inner peripheral shape of the spectacle frame F. Adjacent coordinate acquisition points are selected to be equiangular with respect to the origin or any other point. In addition, the contour shape data 32 includes the coordinate value of the eye point E (the pupil position at the time of wearing projected on the XY plane, which matches the optical center C of the eyeglass lens G unless there is a prism). The contour shape data 32 is acquired as representing the contour of the top of the bevel shape, the deepest portion of the groove shape, and the flat portion, but represents the contour of the finished surface W1 (or the construction surface W2) of the spectacle lens G. May be acquired.
The side peripheral shape of the spectacle lens G, that is, the target lens shape (external shape when the spectacle frame F is mounted) is represented by the contour shape indicated by the contour shape data 32 and the edge shape (side peripheral sectional shape) indicated by the edge shape type data 33. Is done. In the case of a spectacle frame F without a ring-shaped rim such as a rimless (two-point) or a spectacle frame F without a ring-shaped rim before the spectacle lens G is mounted such as a nyroll, the contour shape data 32 is a desired spectacle lens. It may be obtained by causing a spectacle frame tracer to scan a dummy rim (or a dummy lens lens) exhibiting a G lens shape. Regardless of the presence or absence of the ring-shaped rim, the contour shape data 32 may be input from the input means 116 or the scanner that reads the shape described in the drawing, or input by selecting an existing one. Also good. The contour shape data 32 may be obtained by performing a predetermined calculation on the data representing the inner peripheral shape of the rim. That is, the contour shape data 32 may not completely match the rim shape of the spectacle frame F. Similarly, the edge shape type data 33 may not completely match the rim shape of the spectacle frame F.
Note that the coordinate acquisition points may be selected so that adjacent points have the same distance or the same shape length. In addition, it is preferable that the contour shape data 32 is separately left and right, but only one is acquired, and the other contour shape data 32 is calculated as a shape symmetrical to the Y axis using the acquired data. Anyway. Further, the contour shape data 32 may be a set of three-dimensional coordinate values including the Z-axis coordinate values. Further, the edge shape type data 33 may be detected by the contour shape input means 118, or the eyeglass frame F corresponding to the edge shape by the eyeglass frame tracer instead of or together with the edge shape type data 33. The edge shape data obtained by converting the rim shape (the shape corresponding to the bevel, the shape of the protrusion corresponding to the groove, etc.) into data may be used. The contour shape data 32 and the edge shape type data 33 (or edge shape data) may be used in common as the shape data representing the shape of the eyeglass lens G. The edge shape type data 33 may be omitted, and the edge of the already determined cross-sectional shape may be finished. In addition, the eye point E may be handled not as the contour shape data 32 but as the prescription data 4 or the like. Alternatively, the processing may be performed assuming that the eye point E is an origin such as a coordinate acquisition point. Part or all of the calculation related to the contour shape data 32 or the like may be performed in the terminal 3. Further, the spectacle frame tracer is connected to the server 2 (in the manufacturer), the spectacle frame F is sent to the server 2 side (manufacturer) and set in the spectacle frame tracer, and the contour shape data 32 is input to the server 2. May be.

≪Operation etc.≫
12 and 13 are flowcharts according to an operation example of the eyeglass lens manufacturing system 1. Symbols “D” in circles in FIGS. 12 and 13 are connected to each other.
Regarding the operation of each device, the operation of the control means will be described as the operation of the device as appropriate. For example, the operation of the control unit 8 of the server 2 is appropriately described as the operation of the server 2. In the following, the process step is described as S as appropriate. The steps may be appropriately changed to one or more other steps for performing equivalent processing, and the order may be appropriately changed.
The terminal 3 arranged on the side of the orderer including the spectacle store receives the prescription data 4, the edge shape type data 33, and the lens type data 47 from the input means 116 (S1). For example, S power −3.00 and edge thickness 5.0 mm are input as prescription data 4, T−1 is input as edge shape type data 33, and eyeglass lens material is a high refractive index material (thiol) as lens type data 47. Urethane resin) is dyed (brown) and a predetermined HC film or antireflection film is applied.
In addition, the spectacle frame F or the like is set in the contour shape input means 118, the contour shape data 32 is acquired, and the terminal 3 receives the contour shape data 32 (S2). For example, data representing a shape as shown in FIG. 10 is input as the contour shape data 32R.
The terminal 3 stores the set of the prescription data 4, the contour shape data 32, the edge shape type data 33, and the lens type data 47 with an identification symbol for distinguishing it from other sets. When the terminal 3 receives an input of order approval, the terminal 3 transmits these data and identification symbols to the server 2 (S3). At least one of the terminal 3 and the contour shape input unit 118 and the server 2 that acquire the contour shape data 32 constitutes a contour shape data acquisition unit, and the terminal 3 and the input unit 116 that acquire the edge shape type data 33 and the server 2 At least one of them constitutes edge shape data acquisition means.

When the server 2 receives the set of the prescription data 4, the contour shape data 32, the edge shape type data 33, and the lens type data 47, the server 2 stores it for each identification symbol (S4).
And the server 2 calculates the finished surface side mold selection data 23 from the prescription data 4, and transmits it to the finished surface side mold selection device 10 (S5). For example, assuming that the refractive index of the spectacle lens G is 1.60 and the curvature radius of the construction surface W2 is 100.00 mm with S power of −3.00, the curvature radius of the finished surface defining surface 21a is Data indicating that the finished surface side mold 21 of 200.00 mm is selected is generated. The server 2 stores, for each S frequency, a set of the curvature radius of the finished surface defining surface 21a of the finished surface side mold 21 and the curvature radius of the construction surface W2 as a database. To obtain the finished surface side mold selection data 23. Part or all of the calculation of the finished surface side mold selection data 23 may be performed by the finished surface side mold selecting device 10. Further, the server 2 may obtain the finished surface side mold selection data 23 in consideration of the refractive index when the spectacle lens G is manufactured from the material indicated by the lens type data 47 (spectacle lens material). The lens type data 47 (eyeglass lens material) may indicate material properties such as refractive index and transmittance. Further, the lens type data 47 (eyeglass lens material) may be calculated from the prescription data 4 (S frequency, etc.).
Further, the server 2 can obtain the construction surface shape data 50 relating to the curvature radius of the construction surface W2 in the calculation of the finished surface side mold selection data 23 as described above. It transmits to the apparatus 13 (S6).

In addition, the server 2 calculates the work surface side mold shape data 30 from the prescription data 4, the contour shape data 32, and the edge shape type data 33, and transmits it to the three-dimensional printer 11 (S7). A part or all of the calculation of the processing surface side mold shape data 30 may be performed by the three-dimensional printer 11.
For example, the server 2 includes, as the base shape data of the work surface side mold shape data 30, the side periphery defining surface corresponding to the contour shape data 32 including the attachment portion defining surface 31 d having a cross-sectional shape corresponding to the edge shape type data 33. 31c, to-be-processed surface defining surface 31b having a margin with respect to the construction surface W2, the radially outer surface of the recess 31a along the finished surface defining surface 21a, and the side peripheral surface of the finished surface side mold selection data 23 Data having a side peripheral surface arranged at the same position as the above and a surface on the eyeball side that is offset to the eyeball side by a predetermined amount with respect to the work surface defining surface 31b is calculated. The base shape data includes an eye point E. The server 2 may calculate the base shape data of the work surface side mold shape data 30 by referring to the S frequency or the curvature radius of the finished surface defining surface 21a and the curvature radius of the construction surface W2, or may be prescribed. The base shape data may be calculated with reference to other data such as the edge thickness in the data 4.
If the edge shape type data 33 is T-1, the server 2 calculates the attachment portion defining surface 31d that matches the bevel shape. That is, the server 2 uses the data of the attachment portion defining surface 31d in consideration of the shape data of the bevel groove having a deepest portion of 0.7 mm at a position having a horizontal distance of 1.0 mm from the periphery of the finished surface W1.
The server 2 transmits the lens type data 47 to the staining device 14, the HC film forming device 15, and the vapor deposition device 16 (S8).
Furthermore, the server 2 transmits the prescription data 4, the finished surface side mold selection data 23, the lens type data 47, and the construction surface shape data 50 to the inspection device 17 (S9).
In addition, the server 2 transmits the contour shape data 32 and the edge shape type data 33 to the finishing device 18 (S10).
Note that some or all of the calculations performed by the server 2 may be performed by another device such as the terminal 3.

The finished surface side mold selection device 10 that has received the finished surface side mold selection data 23 stores and refers to this, and the finished surface side mold selecting means 24 uses the finished surface side mold selection data 23 to indicate the type of finished surface indicated by the finished surface side mold selection data 23. The side mold 21 is selected from the finished surface side mold stocker 22 and is transported to the three-dimensional printer 11 by transport means (not shown) (S11).
In the case of the above-described finished surface side mold selection data 23, the finished surface side mold 21 in which the radius of curvature of the finished surface defining surface 21a is 200.00 mm is selected.

The three-dimensional printer 11 that receives the processed surface side mold shape data 30 and receives the finished surface side mold 21 corresponding thereto receives the processed surface side mold shape data 30 based on the processed surface side mold shape data 30. Form (S12).
The three-dimensional printer 11 sequentially refers to the processing surface side mold shape data 30 to control the scanning and liquid resin discharge amount in the liquid fixed amount discharge means 34, and to control the UV irradiation to the liquid resin by the UV irradiation means 35. Then, the cured surface side mold 31 is formed. As the liquid resin curable with UV, for example, at least one of a resin mainly containing acrylate (acrylate UV curable resin) and a resin mainly containing epoxy resin (epoxy UV curable resin) is used. In the former, the curing reaction stops immediately after the UV irradiation is stopped, but the volume change before and after curing is relatively large, and the volume after curing shrinks relatively large compared to the volume before curing. In the latter, the curing reaction continues even after UV irradiation is stopped, but the volume change before and after curing is relatively small, and the volume after curing does not shrink much compared to the volume before curing. Such a plurality of types of UV curable resins are selected and used according to the accuracy required for the mold, the curing rate (efficiency), or the like, or are appropriately mixed according to the accuracy and efficiency.

After the formation of the processed surface side mold 31, the three-dimensional printer 11 is in a state where the eye point E of the processed surface side mold shape data 30 coincides with the optical center C of the finished surface defining surface 21 a of the finished surface side mold 21. (Excluding the case where there is a prism), the mold 42 is assembled by disposing the processed surface side mold 31 and conveyed to the lens curing device 12 by a conveying means (not shown). However, when the prism exists, the eye point E is arranged at a predetermined position defined by the prism.
It should be noted that the finished surface side mold 21 and the processed surface side mold 31 may be combined, that is, the mold 42 may be assembled in the lens curing device 12. The three-dimensional printer 11 or another three-dimensional printer may form part or all of the finished surface side mold 21 based on the finished surface side mold selection data 23, the prescription data 4, or the like. For example, a base of the finished surface side mold 21 may be prepared, and an additional portion made of a UV curable resin having a finished surface defining surface 21a matching the S frequency may be formed on the rear surface of the substrate. In this case, the surface including the additional portion made of UV curable resin may be finished by polishing means or the like. Alternatively, the base of the processed surface side mold 31 made of glass or the like is selected from the stocker, and a UV curable resin is deposited by the three-dimensional printer 11 according to the processed surface side mold shape data 30, and an additional portion is added. Thus, the processed surface side mold 31 may be formed. The substrate of the processing surface side mold 31 may be one type or a plurality of types. In the latter case, the substrate is selected from the substrate stocker based on the processing surface side mold shape data 30 and the like. You may do it.

When the lens curing device 12 receives the mold 42, the thermosetting resin material indicated by the lens type data 47 (eyeglass lens material) is poured into the mold 42 to be cured, and is temporarily integrated with the processed surface side mold 31. The semi-finished lens M made of the thermosetting resin thus prepared is produced (S13).
That is, first, the resin material filling means 43 of the lens curing device 12 fills the cavity of the mold 42 with a thermosetting resin material. The resin material filling unit 43 fills the resin material from the filling port J of the mold 42. The resin material filling means 43 may finish filling by grasping that the resin material overflows from the connection portion between the mold 42 or the filling port J and the depression 31a by the sensor, or other device such as itself or the server 2. It is also possible to calculate the filling amount at, and finish filling when the filling amount is reached. In addition, the lens curing device 12 receives the mold 42 in a state where the finished surface side mold 21 and the processed surface side mold 31 are separated from each other, and in this state, fills the recess 31a of the processed surface side mold 31 with a resin material. The finished surface side mold 21 and the processed surface side mold 31 may be combined. In this case, the filling port J may be omitted. Thus, by completing the assembly of the mold 42 after filling the resin material, the resin can be filled into the mold 42 even if the filling port J is not exposed on the side periphery.
The conventional round lens is equivalent to being formed by filling a resin material also in the radially outer portion of the recess 31a of the processed surface side mold 31 of the present invention. Therefore, the use of the resin material in the spectacle lens manufacturing system 1 is used. The amount is greatly reduced compared to the amount used in the production of conventional round lenses. Further, the resin material does not need to be usable in the three-dimensional printer 11, and can be widely used from low cost to high performance (such as those exhibiting a high refractive index after curing). Can be used that have sufficient performance.

Next, the lens curing means 44 heats the mold 42 containing the resin material to cure the resin material, thereby forming a semi-finished lens M made of a thermosetting resin. When the resin material is cured in the mold 42, the finished surface side mold 21 can be made of a sufficiently smooth finish surface defining surface 21a, such as glass, and is an optically important spectacle lens G. The object side surface (finished surface W1) is formed to have sufficient performance as the spectacle lens G.
Subsequently, the partial release means 45 takes out the semi-finished lens M with the processed surface side mold 31 from the mold 42. For example, the partial release means 45 separates the semi-finished lens M with the processed surface side mold 31 from the finished surface side mold 21 by a robot hand. Alternatively, the partly releasing means 45 is provided with a work surface side mold 31 that is placed in a liquid tank for cleaning or the like and separated from the finished surface side mold 21 by the action of the liquid in the liquid tank (in the liquid). Take out the semi-finished lens M. The finished surface W1 of the semi-finished lens M is formed with a radius of curvature of 200.00 mm in accordance with the finished surface defining surface 21a of the finished surface side mold 21, and the rear surface of the portion that becomes the semi-finished lens M is the surface to be processed. The processed surface WP is formed in accordance with the processed surface defining surface 31 b of the side mold 31. The finished surface side mold 21 is collected, returned to the finished surface side mold stocker 22 after being appropriately cleaned.
Then, the lens curing device 12 transports the taken semi-finished lens M with the processed surface side mold 31 to the lab processing device 13 by a transport unit (not shown). The conveying means of the lens curing device 12 can handle the semi-finished lens M without grasping the semi-finished lens M to be the spectacle lens G later by grasping the processed surface side mold 31.

When receiving the construction surface shape data 50 transmitted from the server 2 in S <b> 6, the lab processing device 13 stores the construction surface shape data 50 in association with the identification symbol, and is the same identification symbol as the identification symbol related to the construction surface shape data 50. Is received, the semi-finished lens M with the processed surface side mold 31 is polished based on the construction surface shape data 50 to obtain the round lens body 51 (S14). .
That is, the lab processing apparatus 13 attaches the block piece 59 to the semi-finished lens M with the processed surface side mold 31 and fixes it with a chuck, and polishes the processed surface WP (or its extended surface) by the polishing means 54. Then, a construction surface W2 (or an extended surface thereof) according to the construction surface shape data 50 is obtained. Since the outer shape of the semi-finished lens M with the processed surface side mold 31 is round, a block piece 59 that assumes a round lens can also be used, and the block piece 59 (contact surface 59a) is radially outward from the semi-finished lens M. Can be arranged over the workpiece surface side mold 31 and firmly fixed. Note that the lab processing apparatus 13 may use the block piece 59 without using the block piece 59, and may be polished by fixing the processed surface side mold 31 portion with a chuck. Further, the lab processing apparatus 13 may polish (exactly) only the semi-finished lens M.
In the above-described example, the lab processing apparatus 13 polishes the workpiece surface WP of the semi-finished lens M to produce the round lens body 51 on which the construction surface W2 having a curvature radius of 100.00 mm is formed.
Then, the lab processing apparatus 13 conveys the produced round lens body 51 to the staining apparatus 14 by a conveying means (not shown). The conveyance means of the lab processing apparatus 13 can handle the semi-finished lens M without contacting the portion that will become the spectacle lens G later by grasping the ring-shaped mold 31 ′ of the round lens body 51.

When the dyeing device 14 receives the lens type data 47 transmitted from the server 2 in S8, the dyeing device 14 stores the lens type data 47 in association with the identification symbol. When the lens body 51 is received, the round lens body 51 is dyed based on the lens type data 47 (S15).
That is, the dyeing device 14 attaches the jig 68 to the round lens body 51 and immerses it in the color dyeing solution tank according to the lens type data 47 in a predetermined manner.
Then, the staining device 14 transports the dyed round lens body 51 to the HC film forming device 15 by a transport unit (not shown). The conveyance means of the HC film forming apparatus 15 can handle the round lens body 51 without touching the portion that will become the spectacle lens G later by grasping the ring-shaped mold 31 ′.
In addition, when dyeing is unnecessary, the laboratory processing apparatus 13 does not need to convey the round lens body 51 to the dyeing apparatus 14.

When the HC film forming apparatus 15 receives the lens type data 47 transmitted from the server 2 in S8, the HC film forming apparatus 15 stores the lens type data 47 in association with the identification symbol, and stores the same identification symbol as the identification symbol related to the lens type data 47. When the round lens body 51 is received, an HC film is formed on the surface of the round lens body 51 based on the lens type data 47 (S16).
That is, the HC film forming apparatus 15 puts the round lens body 51 coated with the type of HC liquid according to the lens type data 47 into the colander 78 and puts it into the dryer in a predetermined manner.
Then, the HC film forming apparatus 15 transports the round lens body 51 on which the HC film is formed to the vapor deposition apparatus 16 by a transport unit (not shown). The conveyance means of the HC film forming apparatus 15 can handle the round lens body 51 without touching the portion that will become the spectacle lens G later by grasping the ring-shaped mold 31 ′.
In addition, when the formation of the HC film is unnecessary, the staining device 14 or the like does not have to transport the round lens body 51 to the HC film forming device 15.

Upon receiving the lens type data 47 transmitted from the server 2 in S8, the vapor deposition apparatus 16 stores the lens type data 47 in association with the identification symbol, and has a circle having the same identification symbol as the identification symbol related to the lens type data 47. When the lens body 51 is received, an optical multilayer film is formed on the surface of the round lens body 51 based on the lens type data 47 (S17).
That is, the vapor deposition apparatus 16 applies the optical multilayer film on the surface of the round lens body 51 held by the lens holder 87 at the vapor deposition material and vapor deposition time selected so as to have the layer configuration specified by the lens type data 47. Form.
And the vapor deposition apparatus 16 conveys the round lens body 51 in which the optical multilayer film was formed to the test | inspection apparatus 17 by the conveyance means which is not shown in figure. The conveyance means of the vapor deposition apparatus 16 can handle the round lens body 51 without touching the portion that will become the spectacle lens G later by grasping the ring-shaped mold 31 ′.
In addition, when the formation of the optical multilayer film is unnecessary, the HC film forming device 15 or the like does not have to transport the round lens body 51 to the vapor deposition device 16.

Upon receiving the prescription data 4, the finished surface side mold selection data 23, the lens type data 47, and the construction surface shape data 50 transmitted from the server 2 in S9, the inspection device 17 stores them in association with identification symbols. When the round lens body 51 having the same identification symbol as the identification symbol related to the prescription data 4 or the like is received, the round lens body 51 is inspected based on the prescription data 4 or the like (S18).
That is, the inspection device 17 acquires an image of the round lens body 51 held on the chuck and analyzes whether or not there is a foreign object or the like in the image.
And the inspection apparatus 17 conveys the inspected round lens body 51 to the finishing apparatus 18 by a conveyance means (not shown). The conveying means of the inspection device 17 can handle the round lens body 51 without touching the portion that will become the spectacle lens G later by grasping the ring-shaped mold 31 ′.
In addition, when the inspection before the finishing process is unnecessary, the vapor deposition apparatus 16 or the like does not need to convey the round lens body 51 to the inspection apparatus 17.

Upon receiving the contour shape data 32 and the edge shape type data 33 transmitted from the server 2 in S10, the finishing device 18 stores them and corresponds to the contour shape data 32 and the edge shape type data 33 (these When the round lens body 51 is received (having the same identification code as that of the first embodiment), the ring-shaped mold 31 ′ is released from the pre-finishing spectacle lens G ′ of the round lens body 51, and the contour shape data 32 and the edge shape type are released. The pre-finishing spectacle lens G ′ is cut based on the data 33 to finish the spectacle lens G (S19).
That is, the finishing device 18 separates the additional portion J ′ of the pre-finishing spectacle lens G ′ taken out by the release means 101 based on the contour shape data 32 and the edge shape type data 33 by the cutting means 102, and prescription data. 4 (S frequency, etc.), contour shape data 32 (including eye point E), edge shape type data 33, lens type data 47, and construction surface shape data 50 are produced.
The finishing device 18 selects a grindstone of the cutting means 102 having a grindstone surface corresponding to the edge shape according to the edge shape type data 33, and the cutting means so that the line to be cut matches the contour shape data 32. 102 grindstone is moved. The finishing device 18 may form the side circumference by three-dimensional NC control cutting based on the edge shape data calculated in advance without forming the side circumference of the additional portion J ′ in the shape of the grindstone surface. The side circumference may be formed after cutting or roughing larger than the shape data 32. Further, the finishing device 18 may cut or polish a side peripheral portion other than the connecting portion of the additional portion J ′.

Since the finishing device 18 completes the cutting only by cutting off the additional portion J ′, the cutting time is short and the efficiency is good. Further, the portion that is wasted by the spectacle lens material is only the additional portion J ′ except for the polishing from the work surface WP to the work surface W2.
As shown in FIG. 14, the server 2 uses the smallest elliptic cylindrical surface 131 e (cylindrical surface) in which the side circumference of the recess 131 a is separated from the contour shape data 32 by a predetermined distance or more as the processed surface side mold shape data 30. The three-dimensional printer 11 forms a processed surface side mold 131 having an elliptical columnar depression 131a and forms a mold 142 in combination with the finished surface side mold 21. Then, the lens curing device 12 cures the semi-finished lens M whose side periphery follows the elliptical cylindrical surface 131e by the mold 142 which is handled in the same manner as the mold 42, and the finishing device 18 receives the contour shape data 32 and the edge shape. According to the type data 33, the pre-finishing spectacle lens G ′ whose side circumference follows the elliptical cylindrical surface 131e is cut, and the spectacle lens G May be manufactured. In this case, the recess 131a has a processed surface defining surface 131b similar to the processed surface defining surface 31b. In addition, the ring-shaped mold has an elliptical central hole, so that the ring-shaped mold can be handled easily without touching the portion that becomes the spectacle lens G, and the round mold with the ring-shaped mold is provided. The lens body can be directly put into a device that targets lenses with a round outer shape, the amount of spectacle lens material used is reduced, and a round lens made entirely of spectacle lens material is finished and cut (lens shape processing). The cutting efficiency is better than that of the case. Furthermore, since the side periphery of the recess 131a of the work surface side mold 131 is the elliptical cylindrical surface 131e, the amount of calculation is relatively small. Further, it is assumed that only a predetermined type of processed surface side mold shape data 30 is prepared, and the server 2 includes (the smallest) types of processed surface side mold shape data 30 that can include the entire shape related to the contour shape data 32. It is good to choose.
Further, when the spectacle lens material is not filled via the filling port J, the processed surface side mold shape data 30 matches the side circumference of the spectacle lens G represented by the contour shape data 32 (and the edge shape type data 33). The side periphery defining surface 31c may be generated so that the spectacle lens G is cured by a target lens shape, and the entire finishing process may be omitted. Alternatively, the finishing device 18 may be installed on the orderer side or may be omitted.
Further, as shown by a two-dot chain line in FIG. 8B, a ring-shaped mold 31s ′ having a rectangular side periphery may be formed. In this case, the server 2 calculates, as the processing surface side mold shape data 30, the side circumference of which is rectangular (and has the above-described recess 31 a), and the three-dimensional printer 11 has a rectangular outer shape. The lab processing apparatus 13 forms a pre-finishing spectacle lens with a ring-shaped mold 31 ′ having a rectangular outer shape. Even in this case, the spectacle lens G can be manufactured from the unfinished spectacle lens. Although the rectangular ring-shaped mold 31s ′ cannot be put into the apparatus assuming that the outer shape is circular as it is, once a jig or the like for the rectangular ring-shaped mold 31s ′ is manufactured. A new merit is obtained, for example, that a larger number of rectangular ring-shaped molds 31 s ′ than the round lens body 51 can be arranged in the same space. For example, as shown in FIG. 8B, in the lens holder 87, there are four rectangular rings in the arrangement space of the three round lens bodies 51 (three lens holding holes 87b and its peripheral part). The mold 31s' can be arranged. The side periphery of the ring-shaped mold 31 ′ may be a shape other than a circle or a rectangle, such as an elliptical shape or a polygonal shape.

The spectacle lens G manufactured in this way is appropriately inspected and sent to a place on the ordering side or a place designated by the ordering side. Data indicating these locations may be received and stored in the server 2 from the terminal 3. Also, payment information regarding the spectacle lens G may be similarly received and stored, and the payment information may be used as needed to access the payment side server computer or the like to perform the payment for the spectacle lens G.
On the ordering side or the like, the spectacle lens G is inserted into the corresponding spectacle frame F to complete the spectacles.
The eyeglass lens manufacturing system 1 repeats such an operation as appropriate for each identification symbol (Return To START). The spectacle lens manufacturing system 1 may manufacture the spectacle lens G without obtaining the identification symbol, the contour shape data 32, etc. in the case of securing the stock of the predetermined spectacle lens G. A part or all of them may be reused after washing as appropriate.

<< Effects >>
The spectacle lens manufacturing system 1 includes a mold 42 that is filled with an uncured spectacle lens material, and a lens curing device that cures the spectacle lens material in the mold 42 to form a semi-finished lens M that is the basis of the spectacle lens G. 12, a lab processing apparatus 13 that processes the work surface WP of the semi-finished lens M to be a work surface W2, and a three-dimensional printer 11 that discharges a curable fluid resin. Has a finished surface side mold 21 that defines the finished surface W1 of the semifinished lens M, and a processed surface side mold 31 that defines the side periphery and the processed surface WP of the semifinished lens M. 3 The dimension printer 11 forms the work surface side mold 31 by discharging a fluid resin.
Therefore, the spectacle lens G is formed according to the mold 42 including the workpiece-side mold 31 having an arbitrary shape, and there is a restriction that a lens material that can be used in a three-dimensional printer is used as compared with a case where the spectacle lens G is directly formed by a three-dimensional printer. Therefore, the optical performance and the physical performance are better. At present, a spectacle lens G of an arbitrary shape formed from a lens material that can be used at a realistic cost in a three-dimensional printer has sufficient optical performance and physical performance (equal or better than current general spectacle lenses). Can not be equipped. In contrast, in the eyeglass lens manufacturing system 1, the three-dimensional printer 11 is used to form the processed surface side mold 31, and finish processing is appropriately performed on the semi-finished lens M defined by the mold 42 including the processed surface side mold 31. Thus, the spectacle lens G having an arbitrary shape is manufactured in a state having sufficient optical performance and physical performance. In particular, the finished surface W1 of the spectacle lens G is defined by the finished surface side mold 21 and is optically sufficiently finished. The construction surface W2 of the spectacle lens G is processed by the lab processing device 13 by processing the processing surface WP. Created and optically well finished.
The semi-finished lens M (pre-finishing spectacle lens G ′) is handled with a processed surface side mold 31 (ring-shaped mold 31 ′) (round lens body 51), and is used in various apparatuses for round lenses. It can be used as it is, and the existing facilities can be used effectively.
Further, compared with the conventional round lens, the amount of the ring-shaped mold 31 ′ saves the eyeglass lens material and the work of finishing, and the eyeglass lens manufacturing system 1 is advantageous in terms of cost and environment.

Further, contour shape input means 118 (or the communication means 6 of the server 2) for acquiring contour shape data 32 indicating the contour shape of the spectacle lens G is provided. Are formed in a shape corresponding to the contour shape data 32.
Therefore, the outer shape of the spectacle lens G is formed in a desired shape according to the rim shape of the spectacle frame F, and the amount of spectacle lens material used and the processing amount of the semi-finished lens M are reduced.

The contour shape data 32 is transmitted from the terminal 3 which is the orderer computer.
Therefore, the spectacle lens G having a shape corresponding to the rim shape or the like is manufactured without receiving the spectacle frame F itself from the orderer.

Further, input means 116 (or communication means 6 of the server 2) for acquiring edge shape type data 33 indicating the edge shape of the eyeglass frame F in which the eyeglass lens G is inserted is provided, and the three-dimensional printer 11 is to be processed. The side periphery defining surface 31 c (portion other than the filling port J connection portion) of the surface side mold 31 is formed in a shape corresponding to the edge shape type data 33.
Therefore, the spectacle lens G (pre-finishing spectacle lens G ′, semi-finished lens M) is formed by the mold 42 in a state having an edge shape such as a bevel shape or a groove shape.

The edge shape type data 33 is transmitted from the terminal 3 which is the orderer side computer.
Therefore, the spectacle lens G having a desired edge shape is manufactured without receiving the spectacle frame F itself from the orderer.

In addition, the finished surface side mold 21 is made of glass.
Therefore, the finished surface W1 of the spectacle lens G that is optically important compared to the side periphery is formed sufficiently smoothly. Further, the finished surface side mold 21 can be used repeatedly, and the cost is reduced.

In the eyeglass lens manufacturing system 1, the eyeglass lens material is a thermosetting resin material.
Accordingly, a spectacle lens G made of a thermosetting resin that is easy to manage, such as being excellent in optical performance and physical performance, easy to handle, easy to flow into the mold 42 and hardened in the mold 42 is manufactured.

Further, in the eyeglass lens manufacturing system 1, the three-dimensional printer 11 has a UV irradiation unit 35 that cures the liquid resin. The liquid resin is a UV curable resin, and the UV irradiation unit 35 cures the UV curable resin.
Therefore, the processing surface side mold 31 is easily formed. In particular, when the lens curing device 12 puts the spectacle lens material into the mold 42 and cures it by heating to produce the semi-finished lens M, the surface-side mold 31 can be cured without being heated. Adverse effects such as the start of curing during filling of the lens material, which is assumed when the processing surface side mold 31 is heated, are prevented.

≪Examples of change≫
The liquid resin is a thermosetting resin, and the processed surface side mold 31 is produced by curing by heating (the curing means is a heating means), and the lens curing device 12 puts the spectacle lens material in the mold 42 and heats it. Even when the semi-finished lens M is produced by curing by the above (the lens curing unit is also a heating unit), if the curing temperature of the spectacle lens material is higher than the curing temperature of the processing surface side mold 31, the processing surface The side mold 31 is preheated by fabrication in a state where the above-described adverse effects are avoided, and the efficiency of curing the lens material using the processed surface side mold 31 is improved.
Further, the liquid resin may be a naturally cured resin that is cured by a change in components after ejection. For example, the self-curing resin may be a resin such as an instantaneous adhesive or a caulking agent that cures by reacting with components in the air (moisture, oxygen, etc.) after ejection, or a solvent (moisture or carbonization) after ejection. It may be a dry-curing type resin in which some components such as hydrogen) are naturally separated (evaporated, etc.) and the remaining part such as solute is cured. In this case, the UV irradiation means 35 and the heating means can be omitted, and the configuration becomes simpler.
Alternatively, the liquid resin may be a mixed curable resin that is cured by introducing a specific component (water, a curing resin, or the like) after mixing and mixing or adhering the specific component. In this case, the curing means is a curing component introduction means for introducing (mixing or adhering) a specific component.
The liquid resin (flowable resin) may be cured only on the surface and not inside.

Furthermore, as shown in FIG. 15, the processed surface side mold may be a side peripheral side mold 231 formed so as to open to one side (upward). In this case, the filling port J can be omitted.
That is, as shown in FIG. 15A, the three-dimensional printer 11 forms the side peripheral mold 231 on the finished surface W <b> 1 of the finished surface side mold 21. The side peripheral mold 231 itself has a ring shape (doughnut shape).
The side peripheral mold 231 formed on the finished surface W1 of the finished surface side mold 21 has an opening J2 that opens upward above the construction surface W2. The side peripheral mold 231 is formed so as to define a part of the side periphery of the semi-finished lens M or the spectacle lens G similarly to the side peripheral defining surface 31c, and further formed to extend to the opening J2. It has a side periphery defining surface 231c and an attachment portion defining surface 31d.
As shown in FIG. 15 (b), the resin material filling means 43 of the lens curing device 12 is filled into the side peripheral mold 231 formed in this way through the opening J 2. After filling, a protective mold CV that covers at least a part of the resin material (semi-finished lens M) may be disposed (by a protective mold disposing means such as a robot hand) above the opening J2. Since the surface of the semi-finished lens M on the side close to the protective mold CV becomes a surface to be processed WP and is processed later, the protective mold CV needs to be of an extent that finishes the optical surface (for example, a thick glass plate). Alternatively, a simple one (for example, a glass thin plate or a resin sheet) may be used.
Then, the resin material is cured by the lens curing unit 44 of the lens curing device 12, and the finished surface side mold 21 (and the protective mold CV) is partially released by the mold release unit 45 as shown in FIG. Mold is released.
Next, as shown in FIG. 15 (d), the semi-finished lens M with the side peripheral mold 231 obtained by mold release is subjected to lab processing after the block piece 59 is attached to the finished surface W1. Lab processing is performed in the apparatus 13, and a round lens body 51 as shown in FIG. 15E is obtained. The semi-finished lens M with the side peripheral mold 231 may be introduced into the lab processing apparatus 13 with the protective mold CV attached, and the protective mold CV may be released by lab processing.

Further, regarding the fluid resin discharge means, a resin discharge dispenser (dispenser) may be used instead of the three-dimensional printer.
The three-dimensional printer can deposit a fluid resin, whereas the dispenser discharges the fluid resin without depositing it.

FIG. 16 is a block diagram of the dispenser 211. In addition, the same code | symbol is attached | subjected to the part similar to the three-dimensional printer 11, and description is abbreviate | omitted suitably.
The dispenser 211 as the fluid resin discharging means includes a side peripheral portion having a shape based on the side peripheral side mold shape data 230 by curing a viscous resin, which is a highly viscous fluid resin cured by UV, by UV irradiation. The processed surface side mold 131 is formed.
The dispenser 211 includes a viscous resin discharge unit 234, a UV irradiation unit 35, a connection unit 36, a storage unit 37 that stores various data and programs, and a processed surface side mold 131 for the finished surface side mold 21. A fixing means 239 for fixing and a control means 238 for controlling these are provided.
The processed surface side mold 131 has the same shape as the processed surface side mold 131 of FIG. 14, and unlike the case where all are formed by the three-dimensional printer 11, the processed surface side mold 131 has a processed surface defining surface 131 b in advance. The formed plate-like body (which may be a film) is formed by adding a radially outer side peripheral portion (ring-shaped mold portion) of the recess 131 a with a dispenser 211. The shape of the side periphery portion is represented by the side periphery side mold shape data 230. The plate-like body occupies a portion on the Z axis positive side with respect to the processing surface defining surface 131 b in the processing surface side mold 131, and has the same outer shape as the finished surface side mold 21.
The viscous resin discharging means 234 discharges the viscous resin along the shape of the side peripheral portion of the processing surface side mold 131 based on the side peripheral mold shape data 230. The viscous resin discharge means 234 does not place a viscous resin on the viscous resin and does not deposit the viscous resin. The viscous resin discharge means 234 discharges the viscous resin in a state having a height equal to or greater than the largest thickness in the side peripheral mold shape data 230. The viscous resin can be discharged by the viscous resin discharge means 234, and has a viscosity such that the shape change after the discharge hardly occurs when there is no external force other than gravity.
A plate-like body (base) is introduced into the dispenser 211 with the processing surface defining surface 131b facing upward, and the nozzle of the viscous resin discharge means 234 is disposed above the processing surface defining surface 131b. Then, the control means 238 moves the nozzle of the viscous resin discharge means 234 relative to the plate-like body based on the side circumferential mold shape data 230 while discharging the viscous resin, and the viscous resin discharge means 234 Then, a viscous resin is placed in a shape according to the mold data 230 on the side circumferential side with respect to the work surface defining surface 131b (the radially outward extension surface) of the plate-like body. Here, the nozzle of the viscous resin discharge means 234 puts the viscous resin on the radially outward portion of the oval cylindrical recess 131a in FIG.
Note that the viscous resin discharge means 234 responds to the thickness (height) of the side peripheral side mold shape data 230 (to some extent) by controlling the discharge amount (discharge speed) and the movement speed of the viscous resin discharge means 234. Viscous resin may be discharged. Further, as the viscous resin, a naturally cured resin having viscosity such as a caulking agent such as a silicon caulking agent may be used.

Thereafter, the dispenser 211 uses the fixing means 239 that refers to the side peripheral mold shape data 230 to the processed surface side mold against the finished surface defining surface 21 a of the finished surface side mold 21 received from the finished surface side mold selecting device 10. 131 is fixed so that the thickness of the actual side peripheral portion thereof matches the thickness of the side peripheral portion of the processed surface side mold 131 in the side peripheral side mold shape data 230.
As the fixing means 239, a position adjusting means (robot arm or the like) (not shown) for adjusting the relative position of the processed surface side mold 131 (the plate-like body) with respect to the finished surface side mold 21, and the finished surface side mold 21 or the like. The combination of the support means (a gasket, a superposition | polymerization tape, etc.) affixed over the to-be-processed surface side mold 131 and supporting these is illustrated.
The support means may be one that supports by other than pasting, and may support either the finished surface side mold 21 or the processed surface side mold 131. Further, the support means may be omitted, and the processed surface side mold 131 may be attached to the finished surface side mold 21 by the viscosity of the viscous resin in the side peripheral portion of the processed surface side mold 131. Furthermore, the part of the viscous resin placed at a height exceeding the thickness in the side circumferential mold shape data 230 is crushed and deformed by the finished surface side mold 21 fixed at a predetermined distance from the plate-like body. The server 2 may generate the side peripheral mold shape data 230 in which the deformation (particularly inward deformation) is taken into consideration (enlarged by the inward deformation), or the server 2 may be deformed. The side peripheral mold shape data 230 generated without considering the above may be converted into data that the dispenser 211 considers deformation. In addition, the viscous resin is placed in accordance with the enlarged side circumferential mold shape data 230 with a margin for the expected deformation inwardly related to the viscous resin, and the finishing apparatus 18 cuts the margin. May be.

The UV irradiating means 35 is a viscous resin placed in a shape according to the side peripheral mold shape data 230, or a finished surface side mold 21 or a plate shape fixed at a predetermined distance with the viscous resin sandwiched therebetween. The body is irradiated with UV (at one time or a plurality of times or divided into parts) to cure the viscous resin and form the processed surface side mold 131, and at the same time, the finished surface side mold 21 and the processed surface The formation of the mold 142 combined with the surface-side mold 131 is completed. The dispenser 211 conveys the mold 142 thus formed to the lens curing device 12. The mold 142 is handled in the same manner as the mold 42 thereafter. However, when the supporting means is used, the partial releasing means 46 of the lens curing device 12 removes the supporting means before releasing the finished surface side mold 21.
The viscosity of the viscous resin is preferably 500,000 mPa · s (millipascal second) from the viewpoint of easily maintaining the shape on the finished surface defining surface 21a of the finished surface side mold 21 or the plate-like body even before curing. More preferably, it is 1 million mPa · s or more. However, the viscosity of the viscous resin is based on the premise that it can be discharged, and is preferably determined based on the balance between the ease of discharge and the above-described shape retention. The viscous resin may be cured by heat, or may be cured by heat and UV irradiation.
Further, the side peripheral side mold shape data 230 may be two-dimensional data other than the thickness, and may be attached to the two-dimensional side peripheral side mold shape data 230 or separately from the side peripheral side mold shape data 230. Further, distance data that is data of the distance between the finished surface side mold 21 and the plate-like body according to the thickness of the semi-finished lens M obtained from the prescription data 4 may be provided. In this case, the distance data may be related to the distance between the center of the finished surface side mold 21 and the center of the plate-like body according to the planned center thickness of the semi-finished lens M. It may be related to the distance inside the viscous resin (indented portion 131a) according to the edge (edge) thickness of the semi-finished lens M, or occurs when the expected thickness of the semi-finished lens M is secured. It may relate to the distance between the edge of the finished surface side mold 21 and the edge of the plate-like body, or a combination thereof. The distance data may be received by the server 2 or may be calculated by the dispenser 211. In addition, if the processing surface WP of the semi-finished lens M is processed so as to reduce the thickness to obtain the construction surface W2, the accuracy of the thickness of the semi-finished lens M has a margin, and the margin Therefore, a margin may be given to the accuracy of the control related to the distance between the plate-like body and the finished surface side mold 21, or the distance may not be controlled in anticipation of the margin.
Alternatively, the finished surface side mold selection device 10 may select a plate-like body in addition to the finished surface-side mold 21 and send it to the dispenser 211, and the dispenser 211 may use the received plate-like body. The plate-like body may have an outer shape other than a circle according to the finished surface side mold 21, and the base may have a shape other than the plate-like body.
Furthermore, the finished surface side mold 21 may be combined after the viscous resin is cured (after the formation of the processed surface side mold 31). The viscous resin may be discharged onto the finished surface W1 of the finished surface side mold 21. In addition, after the viscous resin is cured, the support means of the fixing means 239 may be removed before being transported to the lens curing device 12 or after being transported to the lens curing device 12.

When the dispenser 211 is used as the flowable resin discharging means, the spectacle lens manufacturing system is a base for the spectacle lens G by curing the spectacle lens material in the mold 142 and filling the spectacle lens material before curing. A lens curing device 12 that forms the semi-finished lens M, a lab processing device 13 that processes the work surface WP of the semi-finished lens M to be the construction surface W2, and a dispenser 211 that discharges a curable fluid resin The mold 142 includes a finished surface side mold 21 that defines the finished surface W1 of the semifinished lens M, and a processed surface side mold 131 that defines the side periphery and the processed surface WP of the semifinished lens M. A plate with a side circumferential mold). The side circumference portion cumene side mold 131 is formed by discharging a fluid resin (viscosity resin).
Therefore, similarly to the case where the three-dimensional printer 11 is used, the optically excellent spectacle lens G is manufactured in a state where the usage amount of the spectacle lens material, the processing effort, and the burden on the environment are reduced. The semi-finished lens M is handled with a processed surface side mold 131 (ring-shaped mold) having a circular outer shape, and can be directly introduced into various apparatuses for round lenses. Can be used effectively.
Compared with the three-dimensional printer 11, the dispenser 211 has a relatively low accuracy in that the liquid resin is deposited (laminated) and does not form a processed surface side mold. Since the laminating step for depositing the resin is omitted, the manufacturing time of the processed surface side mold is relatively short. Here, the accuracy will be described in detail. When the dispenser 211 is used, fixing means 239 for fixing the finished surface side mold 21 relative to the plate-like body at a predetermined distance is provided, or the processing surface WP is Although the accuracy of the optically most important shape in the height direction (Z-axis direction) can be ensured by setting the construction surface W2 or the like, the X axis of the viscous resin can be obtained by pressing the finished surface side mold 21 or the like. The accuracy in the X-axis direction and the Y-axis direction is relatively low due to deformation in the direction and the Y-axis direction. The relatively low accuracy in the dispenser 211 can be covered by finish cutting.
In particular, when manufacturing a spectacle lens G having a deep curve, there is a difference in height in the processed surface side mold 31 (recessed portion 31a). In general, in the three-dimensional printer 11, the nozzle basically moves in parallel. However, it is relatively difficult to control a large height difference, and control and manufacturing are relatively troublesome. However, in the dispenser 211, there is generally no restriction on parallel movement for resin deposition, and a required amount of liquid resin is not deposited. Therefore, control and manufacturing are relatively easy even when there is a difference in height.
Furthermore, since the fixing means 239 for fixing the finished surface side mold 21 at a predetermined distance relative to the plate-like body is provided, the height of the viscous resin discharged from the dispenser 211 on the plate-like body is high. Even if it is somewhat distant from the original height (the height that should be provided as the side peripheral portion of the processed surface side mold 31), the viscous resin is brought to the original height when the finished surface side mold 21 is arranged by the fixing means 239. It is possible to form the mold 142 with which the thickness of the semi-finished lens M, which is important for achieving the desired optical performance, is surely appropriate.
