Description

[0001] MACHINING APPARATUS FOR EYEGLASS LENSES [0002]

The present invention relates to a spectacle lens processing apparatus for processing an edge of a spectacle lens.

In the spectacle lens processing apparatus, a lens held (sandwiched) by a lens chuck is rough-machined by a roughing grindstone. Thereafter, it is finished by a finishing-processed grindstone or the like (see, for example, USP6283826 (JP-A-11-333684)). When the lens is held on the lens chuck, the base of the cup fixed on the lens surface is attached to the cup holder of the lens chuck. Then, the other chuck is moved to the lens side to hold the lens. Further, the cup is mounted by the cup mounting device at the center of the optical center of the lens or as the geometric center of the target lens shape (see, for example, USP6798501 (JP-A-2001-62688)). The cup mounting device is also referred to as a blocker.

However, in lens processing, when the dioptric power of the right and left lenses (spherical power, diopter power, axis angle) is different, it is important that the left and right lenses are processed correctly. For this reason, the operator (maker) is careful not to mistake the left and right. As a countermeasure, a mark or the like for identifying the left and right sides of the lens with a pen or the like is applied to the lens surface.

Further, there has also been proposed a cup in which the left and right sides can be distinguished according to the cup in which the concavity or the presence or absence of the hole is formed at the base of the cup (for example, see Japanese Patent Application Laid-Open No. 8-252754).

However, in the method of performing marking with a pen on the lens surface, it is necessary to carry out the operation of marking and to erase the mark. This is troublesome for the operator. Also, in the case of a water-repellent coated lens, no mark can be attached.

It is impossible to change the shapes of the left and right cups by changing the shape of the base of the cup by forming the concave portion or the hole. Because of this, the concave portion and the hole are small, so that it is not easy to distinguish at first sight.

An object of the present invention is to provide a spectacle lens processing apparatus capable of further reducing the right and left error during lens processing.

In order to solve the above problems, the present invention is characterized by having the following configuration.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig. 1 shows an appearance of a spectacle lens processing apparatus and a cup mounting apparatus according to the present invention.

<Cup mounting device>

The configuration of the cup mounting apparatus 1 will be described with reference to Figs. 1 and 2. Fig. Fig. 2 shows an optical system, a blocking mechanism and a control system arranged in the apparatus 1. Fig.

On the lower side of the device 1, a pedestal 1a is located. On the upper surface of the pedestal 1a, a transparent acrylic lens table 10 is mounted via a ring member 11. On the lens table 10, three support pins 12 are formed at equal intervals around the reference axis L1 of the cup to support the lens LE.

On the front surface of the pedestal 1a, a switch 2a for operating the blocking mechanism portion 30 (to be described later) is disposed. Further, a switch 2b for selecting the right and left sides of the lens is disposed. A suitable space is secured between the lower surface of the upper portion 1b extending to the front side of the device 1 and the pedestal 1a. This space is for the operator to hold the lens LE in his hand and to move on the lens table 10 and to lift the cup 25 mounted on the tip of the cup mounting arm 31.

The apparatus 1 is provided with a detection optical system 9 for illuminating the lens LE and detecting the optical center and axis angle of the lens LE. The configuration of the detection optical system 9 is shown below.

The illumination light source 20 is disposed in the rear of the lens table 10 in the vicinity thereof. The concave mirror 21 has a mirror curved surface in which the illumination light from the illumination light source 20 is shaped into a substantially parallel light beam having a diameter larger than that of the lens LE. Then, a substantially parallel light flux is projected along the reference axis L1.

At the center of the lens table 10, an index portion 13 having a predetermined pattern around the reference axis L1 is formed. The land portion 13 is composed of a dot index arranged in a lattice pattern. The dot index has a size of 0.3 mm in diameter. The indexes are arranged at intervals of 0.3 mm in the range of 20 mm square with the reference axis L1 as the center. A screen plate 14 made of translucent material such as opaque glass is disposed under the lens table 10. The light flux transmitted through the lens LE illuminates the surface portion 13 on the lens table 5. The screen plate 14 projects the entire image of the lens LE and the dot index image subjected to the prism action of the lens LE. Further, a mirror 15 is disposed below the screen plate 14. A first CCD camera 17 is provided in the reflection direction of the mirror 15. The first CCD camera 17 has a lens for magnifying and capturing only a central region centered on the reference axis Ll so as to be able to detect an index image projected on the screen plate 14. A half mirror 16 is disposed in the optical path between the mirror 15 and the first CCD camera 17. A second CCD camera 18 is provided in the reflection direction of the mirror 16. The second CCD camera 18 has a lens for imaging the entire image of the lens LE projected on the screen plate 14.

A method of obtaining the optical center position and the axis angle of the lens LE from the image of the dot index image obtained by the first CCD camera 17 will be described. When the lens LE is not mounted, the dot index of the land portion 13 is illuminated by the parallel light flux. For this reason, the surface image is projected on the screen plate 14 as it is. When the lens LE having the refractive power is mounted, the dot image positioned just below the optical center of the lens LE is the same regardless of the presence or absence of the lens LE. By the way, the dot image of the portion which is not the optical center of the lens LE is shifted by the prism action. Therefore, in order to detect the optical center, a change in the coordinate position of each dot image in a state in which the lens LE is mounted is grasped with respect to the coordinate position of each dot image in the absence of the lens LE. Then, it is determined which position of each dot image is diffused or converged. The center of this diffusion or convergence is the optical center.

Further, when the lens LE has astigmatic dioptric power, each dot image moves in the direction toward (or away from) the generatrix of the lens. Therefore, the axis angle is detected by examining in which direction each dot image is moving with respect to the coordinate position of each dot image in the absence of the lens LE.

2, the blocking mechanism unit 30 includes an arm 31 on which a cup holder 31a to which a base of the cup 25 is to be mounted and an arm 31 on which the arm 31 is moved in the Y axis direction A Z-axis direction moving unit 34 for moving the arm 31 in the vertical direction (Z-axis direction) together with the unit 32, and a Z- 31) in the X-axis direction in the left-right direction (X-axis direction) toward the front face of the apparatus 1. The X- These mobile units 32, 34, and 36 may each be constructed of a known moving mechanism having a slide mechanism and a motor or the like. The cup holder 31a is mounted on the arm 31 so as to be rotatable about the axis extending in the vertical direction. The Y-axis direction moving unit 32 is provided with a drive unit 38 having a motor for rotating the cup holder 31a. The driving force of the rotation by the drive unit 38 is transmitted to the cup holder 31a through the rotation transmitting mechanism (composed of gear, rotary shaft, etc.) disposed in the arm 31. [ The cup holder 31a is rotated about the vertical axis so that the angle of the cup 25 is adjusted according to the astigmatism time of the lens LE.

A spectacle frame shape measuring unit 5 is arranged at the rear of the apparatus 1. [ A color liquid crystal display 3 for displaying a lens image and various information captured by the second CCD camera 18 and an operation switch unit 4 of the unit 5 are arranged on the upper surface of the apparatus 1. [ The display 3 has a touch panel function.

The unit 5, the display 3, the CCD cameras 17 and 18, and the like are connected to the control unit 50. [ The control unit 50 obtains the optical center position and the axis angle of the lens LE based on the output signal from the CCD camera 17. [ The control unit 50 also controls driving of each unit, display of the display 3, and the like.

&Lt; Spectacle lens processing device &gt;

The configuration of the spectacle lens processing apparatus 200 will be described with reference to Figs. 1 and 3. Fig. 3 shows a processing mechanism inside the apparatus.

The carriage 100 is mounted on a base 170. The lens LE is held by the lens chucks 102L and 102R of the carriage 101 constituting the carriage unit 100. [ The edge of the lens LE is mounted on a grindstone spindle 161 and the distances of the chucks 102L and 102R to the grindstone group (group) 162 rotated by the motor 160 are controlled Processed. The grindstone group 162 includes a plastic grindstone 162a, a bevel finishing and plane-finishing grindstone 162b, a polishing finishing grindstone 162c, And a grindstone 162d.

The lens chuck shaft 102L is held on the left arm 101L of the carriage 101 and the lens chuck 102R is held coaxially on the right arm 101R so as to be rotatable. The lens chuck shaft 102R is moved toward the lens chuck 102L by the motor 110 mounted on the right arm 101R. Then, the lens LE is held by the two lens chucks 102R and 102L. The two lens chucks 102R and 102L are rotated synchronously by a motor 120 mounted on the left arm 101L through a rotation transmitting mechanism such as a gear. A cup holder 130 to which a base portion 25a of the cup 25 is attached is fixed to the distal end side of the lens chuck shaft 102L. On the tip side of the lens chuck 102R, a lens pressing member 135 which is brought into contact with the rear surface of the lens LE is fixed (see Fig. 6).

The carriage 101 is mounted on an X-axis movable support base 140 which can move along shafts 103 and 104 extending in parallel with the grindstone spindle 161. At the rear of the support base 140 is mounted a ball screw extending parallel to the shaft 103 (not shown). The ball screw is mounted on the rotating shaft of the X-axis moving motor 145. The rotation of the motor 145 moves the carriage 101 together with the support base 140 in the X-axis direction.

Shafts 156 and 157 extending in the Y-axis direction (direction in which the distance between the axes of the lens chucks 102R and 102L and the grindstone spindle 161 change) are fixed to the support base 140. [ The carriage 101 is mounted on the support base 140 so as to be movable in the Y-axis direction along the shafts 156 and 157. A Y-axis moving motor 150 is fixed to the support base 140. The rotation of the motor 150 is transmitted to a ball screw 155 extending in the Y-axis direction. Then, the carriage 101 is moved in the Y-axis direction by the rotation of the ball screw 155.

In Fig. 3, a chamfering mechanism unit 180 is disposed in front of the processing device 200. Fig. An edge path position measuring section (lens shape measuring section) 300F and 300R is provided above the carriage 101. [ On the rear side of the carriage section 100, a hole forming and groove forming mechanism section 190 is disposed. These configurations are well known. Therefore, the description is omitted here.

1, on the upper surface of the processing device 200, a color display 210 having a touch panel function, an operation switch panel 220, a red LED 230R as display means for displaying left and right identification information of the lens, And a green LED 230L are arranged. The opening and closing door 201 is disposed on the upper surface of the processing apparatus 1. [

4 is a block diagram illustrating a control system of the machining apparatus 200. As shown in Fig. The display unit 210, the panel 220, the LEDs 230R and 230L, and the like are connected to the controller 250. Further, the cup mounting apparatus 1 is connected to the control section 250. Thus, data transmission / reception is performed between the cup mounting apparatus 200 and the processing apparatus 200.

<Lens fixing cup>

5 is a view for explaining the cup 25 as a jig fixed to the lens LE. 6 is a view for explaining the configuration of the cup holder 130 provided on the lens chuck shaft 102L and fitting the cup 25 to the holder 130. Fig.

The cup 25 is used separately according to the cup 25R fixed to the right eye lens and the cup 25L fixed to the left eye lens. The shapes of the cup 25R and the cup 25L are the same, but the colors applied are different from each other in order to distinguish the left and right. For this reason, in Figs. 5 and 6, an east arc is attached to the components of the cup 25R and the cup 25L. The cups 25R and 25L have a base portion 25a and a flange 26 which are inserted into the insertion hole 131a of the cup holder 130. [ A key groove 25b is formed in the base portion 25a. Further, the key groove 25b is fitted to the key 131b formed in the insertion hole 131a. Thereby, the angle of the chucks 102L, 102R relative to the lens LE can be kept constant. A notch 25c for determining the vertical position of the lens is formed in the base portion 25a. The flange portion 26 is provided with a recessed portion 26a around the base portion 25a in order to reduce the deviation of the rotation direction with respect to the cup holder 130. [ At the end of the cup holder 130, concave and convex portions fitted to the concave and convex portions 26a are also formed. By moving the lens chuck 102R to the lens LE side after the base portion 25a of the cup 25R or 25L with the lens LE fixed thereon is mounted on the cup holder 130, It comes into contact with the back of the lens. Thereby, the lens LE is held by the two lens chucks 102R and 102L.

The cup holder 31a of the cup mounting apparatus 1 is formed with an insertion hole and a key in the same manner as the cup holder 130. Its shape is the same as that of the cup holder 130, and a description thereof will be omitted.

It is preferable that the difference in apparent color between the cup 25R and the cup 25L is easy to understand. In the present embodiment, the entire cup 25R is made in red, and the entire cup 25L is made green. In the case where the cups 25R, 25L are integrally formed of a resin, a mixture of red and green coloring agents can be imparted to the resin material as a whole, simply as a whole. Further, the cup may be colored after coloring. It is also preferable that the portion to which the color is imparted is apparently difficult to impart to the entire cups 25R, 25L. However, it may be partially given. In the case where the color is partially given, for example, the flange portion 26 which is easy to be recognized because of its large area is preferable.

In the present embodiment, the flange portion 26 has a size larger than the diameter of the cup holders 130 and 31a. At this time, even after the base portion 25a is attached to the cup holder 130 (31a), the flange portion 26 is exposed to the outside. Therefore, the operator can easily distinguish the color difference. The end portion of the flange portion 26 is formed to a thickness of about 2 mm. Therefore, even if the cup 25R, 25L is attached to the cup holder 130 (31a), the color can be easily confirmed from the side surface if the thickness direction (side face) of the flange portion 26 is also colored .

Next, the operation of the cup mounting apparatus 1 and the machining apparatus 200 using the cups 25R, 25L will be described. Initially, an operation of fixing the cups 25R, 25L to the left and right lenses respectively by the cup mounting apparatus 1 will be described.

The lens-shaped data measured by the spectacle frame shape measuring unit 5 is stored in the memory 6. [ An input screen as shown in Fig. 7 is displayed on the display 3. Fig. The screen displays the meaning of inputting a job number (job number) managed by a pair of left and right lenses (LE). Then, the operator inputs the job number by operating the numerical keypad displayed by pressing the job number input field 61. [ By operating each key of the machining condition selection box 62, the machining conditions such as the material of the lens, the type of lens (short focus lens, bifocal lens, etc.) and the machining mode are inputted. The layout data can be input by the operation of each key of the layout input field 65. [ Lens data, processing conditions, and the like are stored in the memory 51 in association with job numbers.

Further, the operator selects either the right or left lens LE with the left / right selection keys 63R, 63L. The left and right can also be selected by the switch 2b. Here, the case where the right eye lens is selected will be described. At this time, the display area of the key 63R is displayed in red, which is the same color (including the approximate color) corresponding to the red color imparted to the cup 25R, under the control of the control unit 50 based on the selection signal do. The display of the key 63L on the non-selected side becomes the same color as the background of the layout screen 64. [ On the other hand, when the lens for the left eye is selected, the display area of the key 63L is displayed in green by the control unit 50, which is the same color (including the approximate color) corresponding to the green attached to the cup 25L. In this manner, the display areas of the keys 63R and 63L on the display 3 are used as left and right display means for displaying left and right identification information in colors corresponding to the cups 25R and 25L. The operator confirms the correspondence relationship between the display colors of the keys 63R and 63L and the colors of the cups 25R and 25L. When the right eye is selected, the red cup 25R is attached to the cup holder 31a. When the left eye is selected, the green cup 25L is attached to the cup holder 31a.

Further, the flange portion 26 is also colored. Therefore, even after the cup 25R or 25L is mounted on the cup holder 31a, the color of the flange portion 26 can be recognized. It is possible to easily confirm whether one of the left and right cups 25R or 25L is attached to the holder 31a by the correspondence relationship between the display color for left and right identification of the display 210. [

The means for displaying the left and right identification information in the colors corresponding to the left and right cup colors is not limited to changing the display colors of the keys 63R and 63L. For example, the color of the background displayed on the display 3 may be changed in whole or in part. The background of the layout screen 64 may be displayed in red when the right eye is selected and green when the left eye is selected. The color corresponding to the color of the selected cup is displayed in a large area, so that the selection situation of the left and right can be grasped visually. Further, the display of the left and right identification information corresponding to the color of the cup is not limited to the display of the display 3. [ Other display devices may be provided. For example, the red LED 53R and the green LED 53L may be disposed in the vicinity of the switches 2a and 2b. When the right eye lens is selected, the red LED 53R is turned on in response to the selection signal. When the left eye lens is selected, the green LED 53L is turned on in response to the selection signal.

Input of layout data will be described. The operator can input layout data such as frame pupillary distance (FPD), pupillary distance (PD), optical center height of the lens with respect to the geometric center of the lens type, and the like by operating each key of the layout input field 65. In addition, the astigmatic axis angle of the prescription data of the lens LE can be input. Further, the block center of the lens can be selected as the optical center (optical center) or the frame center (the center of the geometric center of the lens type).

The mounting of the cup to the left and right lenses LE will be described. For example, the case where the left eye lens is selected by the key 63L will be described. First, the operator places the central portion of the lens LE for the left eye near the center of the three support pins 12. Then, the image of the land projected on the screen plate 14 is picked up by the first CCD camera 17. Then, the optical center of the lens LE and the direction of the astigmatic axis are detected by the control unit 50. The optical center mark MFO is displayed on the layout screen 64 on the basis of the detected optical center together with the lens-like figure FT. The operator can perform the alignment by moving the lens LE with reference to the cup mounting center of the reference axis L1. The arm 31 of the blocking mechanism section 30 is three-dimensionally moved by control to the control section 50 and the cup holder 31a is rotated The mounting angle of the cup changes automatically.

When the switch 2a is pressed, the control unit 50 controls each of the moving units of the mechanical unit 30 to move the arm 31 based on the optical center and layout data of the lens and the like. Further, the control unit 50 rotates the cup 25L mounted on the cup holder 31a. Further, when the alignment position is determined, the controller 50 causes the arm 31 to descend. Thereby, the cup 25L is fixed to the surface of the lens LE. In this way, the operator mounts the cups 25L and 25R on the pair of left and right lenses LE, respectively. Further, the cups 25L and 25R of the present embodiment fix the lens LE and the cups 25L and 25R with the adhesive double-faced tape interposed therebetween. However, the present invention is not limited to this, and the flange portion 26 may be a cup formed by a suction rubber.

Next, lens processing by the processing apparatus 200 will be described. 8 is an example of a data input screen displayed on the display 210. In FIG. The worker inputs the job number by the numeric keypad displayed by pressing the job number input field 212. Thereafter, the control unit 250 calls the lens type data and the layout data corresponding to the job number from the memory 51 of the cup mounting apparatus 1. [ Then, their data is stored in the memory 251 of the processing device 200 side. Based on the called layout data and the processing condition data, each display column at the bottom of the screen is set. Further, the right lens type (FTR) and the left eye type (FTL) are displayed on the upper part of the screen. In addition, the geometrical center FC and optical center MFO of each lens type are graphically displayed. The layout data and the processing condition data may be input on the side of the processing device 200. [

8, left and right selection keys 214R and 214L as means for selecting which of the right and left sides of the lens LE to be processed are displayed are displayed in the upper part of the screen. When the operator presses the right eye key 214R, the display area of the key 214R is displayed in red by the display control of the display 210 by the control unit 250. [ In addition, the color in the right eye lens-like figure (FTR) is displayed in red (including the case of near-color). When the right eye is selected, the left eye selection key 214L and the left eye lenticular figure FTL are fixed to the same color as the background of the screen. On the other hand, when the left eye key 214L is pressed, the display area of the key 214L is displayed in green. At the same time, the color in the left-eye lens-like figure FTL is displayed in green (including the case of near-color). In the left eye selection state, the right eye selection key 214R and the right eye type lens shape FTR are fixed to the same color as the background of the screen.

The operator confirms the colors of these colors and the fixed cups 25R, 25L of the lens LE. Thus, it is possible to visually confirm easily which lens LE to be held on the lens chuck shafts 102R, 102L. That is, when the right eye is selected, the display area of the selection key 214R and the right eye type lens shape FTR are displayed in red. Therefore, the lens LE on which the corresponding red cup 25R is mounted can be mounted on the cup holder 130 of the lens chuck shaft 102L. When the left eye is selected, the display area of the selection key 214L and the lens-like figure FTL are displayed in green. Therefore, the lens LE on which the green cup 25L corresponding to this color is mounted can be mounted on the cup holder 130. [ This makes it possible to largely reduce the mistakes of the left and right of the lens LE. The display colors in the display areas and the lens-like figures FTR and FTL of the selection keys 214R and 214L as the left and right identification information displayed on the basis of the left and right are set to correspond to the color classification of the cups 25R and 25L It is colored. Therefore, the visibility can be significantly improved to facilitate identification of the left and right.

When processing the right eye lens, the base of the cup 25R mounted on the right eye lens LE is attached to the cup holder 130. [ At this time, the portion of the flange portion 26 exposed from the cup holder 130 is also given a red color. Therefore, even after the cup 25R is mounted on the cup holder 130, the color can be visually recognized easily. The operator can be relieved by confirming the correspondence relationship with the display color for left and right identification of the display 210. [ When the chuck switch 220a disposed on the operation switch panel 220 is pressed, the lens chuck shaft 102R is moved to the lens side by the control of the controller 250, and the lens LE is chucked.

As means for displaying left and right identification information corresponding to the colors of the right and left cups, there is a method of changing the display color of the key 214R and the key 214L as well as a method of changing the color of the lower half of the screen in whole or in part . In addition, a separate display device other than the color display 210 may be used. For example, the red LED 230R and the green LED 230L may be disposed in the vicinity of the chuck switch 220a. Thus, corresponding to the left and right selection signals, when the right eye is selected, the red LED 230R is turned on. Further, when the left eye is selected, the green LED 230L is turned on. Since the switch 220a is normally operated when chucking the lens, if the LEDs 230R and 230L are arranged in the vicinity thereof, the color can be confirmed in the work process.

After the lens is chucked, when the machining start switch of the operation switch panel 220 is pressed, the shape of the lens LE is first measured based on the lens type data. Then, each motor of the carriage 100 is controlled. The edges of the lens LE held by the lens chuck shafts 102R and 102L are rough machined by the grindstone 162a and then finished by the grindstone 162b for finishing. When bevel processing is set, bevel calculation is performed based on the position of the covar of the lens, and bevel finishing processing is performed. When the groove forming processing is set, the edge of the lens LE is subjected to the plane processing, and then the groove forming processing is performed by the hole processing / groove forming mechanism unit 190. In the case where there is a designation of hole machining, the edge of the lens LE is subjected to the plain machining, and then the hole machining and groove forming mechanism 190 performs hole machining (see, for example, US Pat. No. 6,790,124 (Japanese Patent Application Laid- 145328)).

When the processing of the right eye lens is completed, the operator selects the processing of the left eye lens by the selection key 214L, and the lens LE on which the green cup 25L is mounted is placed on the lens chuck axes 102R and 102L And the lens LE is processed in the same manner. Also in this case, it is possible to reduce the right and left error by checking the corresponding relationship between the display color in the key 214L and the lenticular figure FTL and the color of the cup 25L.
