[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0027] FIG. 1 is a perspective view showing a schematic configuration of an automatic eyeglass lens fitting device according to an embodiment of the present invention.
[0028] As shown in Figure 1, the automatic eyeglass lens fitting device 1 of this embodiment comprises a platform-shaped fitting device main body 10, an eyeglass frame holder 2 for placing a plastic eyeglass frame 42 on which is provided near the center of the top surface of the fitting device main body 10, a robot arm 3 for transporting the eyeglass frame 42 and lenses 44 provided near the side of the top surface of the fitting device main body 10 to the eyeglass frame holder 2, and a pusher device 7 for fitting the lenses 44 into the lens frame 43 of the eyeglass frame 42.
[0029] Here, as shown in Figure 2, the eyeglass frame holder 2 has a groove 21 into which the eyeglass frame 42 is fitted with the ear hook portion 41 facing upward, and the eyeglass frame 42 can be placed stably on its upper surface.
[0030] In addition, the robot arm 3 is capable of performing tasks by rotating the connection base end 31 and by bending each joint 32, 33, 34 to perform deformation in three dimensions, and can also rotate and switch between arm sections 35 and 36, which have different structures at the tip.
[0031] Here, as shown in Figure 2, the arm portion 35 is structured so that it can grasp the left and right ear hook portions 41 of the eyeglass frame 42 with the gripping portions 35a, 35a at the tip and carry it, and the arm portion 36 is structured so that it can suck up one side surface of the lens 44 with the suction cup portion 36a at the tip and carry it, as shown in Figure 3.
[0032] In this embodiment, the first robot arm and the second robot arm as defined in the claims are the same robot arm 3, but they may be implemented as separate robot arms.
[0033] 1, a water tank 5 as a water washing means and an air blower 6 as a drying means are provided on the top surface of the fitting device main body 10. By using these to wash and dry the lenses 44, which are placed on a tray 8 and have shavings and the like attached thereto after being cut in a factory or the like, they can be cleaned during transport and then set on the lens rim 43 of the eyeglass frame 42 by the robot arm 3.
[0034] As shown in FIG. 1, the pusher devices 7 are disposed on the upper surface of the fitting device main body 10 on both sides of the eyeglass frame receiving mold 2.
[0035] As shown in Figures 4 to 10, this pusher device 7 is equipped with four lens pressing pushers 71,... each having a pressing portion 71a at its tip that can be driven independently to press the lenses 44 set in the lens frames 43 of the eyeglass frame 42 fitted into the eyeglass frame holder 2, and an arm portion 71b that supports this pressing portion 71a.
[0036] Here, the lens pressing pushers 71, ... of the pusher device 7 can be driven independently of the other lens pressing pushers 71 in the front-to-back direction facing the eyeglass frame holder mold 2, the up-down direction, and the oscillating direction in which the pressing portion 71a at the tip thereof oscillates horizontally (see Figures 6 and 7).
[0037] Moreover, the lens pressing pushers 71, . . . can also be driven in the left-right direction perpendicular to the front-rear direction described above.
[0038] More specifically, as shown in FIGS. 6 to 8, the lens pressing pushers 71, . . . are each supported by a pusher support 72.
[0039] The pusher support member 72 is made up of a slide member 721 , a lifting member 722 provided on the top of the slide member 721 , and a pusher support member 723 provided on the top of the lifting member 722 .
[0040] The slide member 721 of this pusher support body 72 is slidable along a guide rail 73 extending in the front-to-rear direction facing the eyeglass frame holder mold 2, and can be driven independently of the other slide members 721 together with the upper lens pressing pusher 71 in the front-to-rear direction facing the eyeglass frame holder mold 2 by an actuator 11 serving as a rear driving means.
[0041] As shown in FIG. 9, the lifting member 722 of the pusher support body 72 is provided with a rotating shaft 74b connected to the upper part of a drive shaft 74a of an electric motor 74 serving as a driving means provided on the slide member 721. A male threaded portion formed on the surface of the rotating shaft 74b is threaded into a female threaded portion 74c formed on the lifting member 722, and when the drive shaft 74a of the electric motor 74 rotates, the lifting member 722 can be driven up and down together with the upper lens pressing pusher 71 independently of the other lifting members 722.
[0042] 9 and 10, a rotation shaft 75b is supported on the pusher support member 723 of the pusher support body 72. The rotation shaft 75b is provided with a gear 75c that meshes with a threaded portion formed on the surface of a drive shaft 75a of an electric motor 75 serving as a drive means provided on the elevating member 722, and the arm portion 71b of the lens pressing pusher 71 fixed to the rotation shaft 75b can be rotated. As a result, the lens pressing pusher 71 can be driven independently of the other lens pressing pushers 71 in the swinging direction in which the pressing portion 71a at the tip swings horizontally by the rotation of the electric motor 75.
[0043] In addition, the four pusher supports 72, together with the guide rails 73, can be driven in the left-right direction, which is perpendicular to the above-mentioned front-to-back direction (the longitudinal direction of the guide rails 73), together with the upper lens pressing pusher 71, by an actuator 12 serving as a side driving means.
[0044] Then, a control unit (not shown) in the fitting device main body 10 drives and controls the lens pressing pushers 71, ... in the pusher device 7 so that each pressing portion 71a presses the surface of the lens 44 at four points.
[0045] More specifically, as shown in Figures 4 and 5, the control unit controls the lens 44 to press the inner corner side of the eye with lens pressing pushers 71, 71 positioned at the inner corner side of the eye, and then to press the outer corner side of the eye with lens pressing pushers 71, 71 positioned at the outer corner side of the eye.
[0046] This allows the lens 44 to be automatically fitted into the lens frame 43 of the eyeglass frame 42.
[0047] Next, with reference to FIG. 11, a method for assembling eyeglasses using the automatic eyeglass lens fitting device 1 according to this embodiment will be described.
[0048] First, the left and right ear hook portions 41 of the eyeglass frame 42 are grasped and removed from the stocker 9 storing the eyeglass frame 42 by the gripping portions 35a, 35a of the robot arm 3, which moves the connection base end 31 and each joint portion 32, 33, 34 to perform three-dimensional deformation movements (step S1).
[0049] Next, the position and angle of the eyeglass frame 42 are measured using image measurement by a camera (not shown) mounted on the fitting device main body 10, a correction value is detected, and based on this correction value, the position and angle of the eyeglass frame 42 are corrected to predetermined values, thereby performing position correction (step S2).
[0050] Then, the eyeglass frame 42 is fitted and placed in the groove 21 of the frame receiving mold 2 by the robot arm 3 which performs a three-dimensional deformation operation (step S3).
[0051] Next, the suction cup portion 36a of the robot arm 3, which is capable of deforming in three dimensions, sucks and removes one of the lenses 44 from the tray 8, and washes it with water in the water tank 5 (step S4).
[0052] Next, the water on the surface of the lens 44 on one side is blown off by air blowing in the air blower 6, and the lens 44 is dried (step S5).
[0053] Next, the position and angle of this lens 44 on one side are measured by image measurement of the lens 44 on one side using a camera (not shown) mounted on the fitting device main body 10, a correction value is detected, and based on this correction value, the position and angle of this lens 44 on one side are corrected to predetermined values to perform position correction, and the thickness of this lens 44 on one side is also measured (step S6).
[0054] Next, the lens 44 on one side is set on the lens frame 43 of the eyeglass frame 42 by the robot arm 3 which performs a three-dimensional deformation operation (step S7).
[0055] At this time, as shown in Figure 3, the robot arm 3 fits the inner corner side of the lens 44 on one side into the inner corner side groove portion 43a of the lens frame 43 of the eyeglass frame 42, and sets the lens 44 on one side in an oblique state so that the outer corner side of the lens 44 on one side is not fitted into the outer corner side of the lens frame 43 of the eyeglass frame 42.
[0056] Then, as shown by the solid line in FIG. 5, the lens 44 on one side is pressed by the lens pressing pushers 71 of the pusher device 7, and fitted into the lens frame 43 of the eyeglass frame 42 (step S8).
[0057] At this time, when a control signal is sent from the control unit to the pusher device 7, first, the actuator 11 is driven, the slide member 721 slides on the guide rail 73, the pusher support body 72 moves forward, and the pressing portion 71a of the lens pressing pusher 71, ... is positioned above the lens 44 on one side.
[0058] Then, the electric motor 74 is driven to lower the lifting member 722, and the inner corner of the lens 44 on one side is pressed by the opposing lens pressing pushers 71, 71 positioned on the inner corner of the eye side.
[0059] As a result, the pressed lens 44 on one side widens the area from the inner corner of the lens frame 43 with a small amount of deformation to the outer corner of the lens frame 43 with a large amount of deformation.
[0060] Subsequently, the electric motor 74 is driven to lower the lifting member 722, and the outer corner of the eye of this lens 44 on one side is pressed by the opposing lens pressing pushers 71, 71 positioned on the outer corner of the eye side.
[0061] As a result, the pressed lens 44 on one side fits into the lens frame 43 of the eyeglass frame 42.
[0062] The position of the pressing portion 71a of the lens pressing pusher 71, . . . before pressing can be finely adjusted by driving the electric motor 75 to move it in the above-mentioned swing direction.
[0063] The control unit also controls the driving of the lens pressing pushers 71, . . . with a pushing amount according to the measured thickness of the lens 44 on one side.
[0064] After the lens 44 on one side is fitted into the lens frame 43 of the eyeglass frame 42, the electric motor 74 is driven to raise the lifting member 722, and the actuator 11 is driven to cause the slide member 721 to slide on the guide rail 73, so that the pusher support 72 moves backward and is retracted.
[0065] Furthermore, the actuator 12 is driven to move the four pusher supports 72 laterally, preparing for the subsequent fitting of the other lens 44.
[0066] Subsequently, the suction cup portion 36a of the robot arm 3, which is capable of deforming in three dimensions, sucks and removes the other lens 44 from the tray 8, and washes it with water in the water tank 5 (step S9).
[0067] Next, the water on the surface of the other lens 44 is blown off by air blowing in the air blower 6, and the lens 44 is dried (step S10).
[0068] Next, the position and angle of the other lens 44 are measured by image measurement of the other lens 44 using a camera (not shown) mounted on the fitting device main body 10, and a correction value is detected. Based on this correction value, the position and angle of the other lens 44 are corrected to predetermined values to perform position correction, and the thickness of the other lens 44 is also measured (step S11).
[0069] Subsequently, the other lens 44 is set on the lens frame 43 of the eyeglass frame 42 by the robot arm 3 which performs a three-dimensional deformation operation (step S12).
[0070] At this time, as shown in Figure 3, the robot arm 3 sets the lens 44 on one side in an oblique state so that the inner corner side of the lens 44 on the other side fits into the inner corner side groove portion 43a of the lens frame 43 of the eyeglass frame 42, and the outer corner side of the lens 44 on the other side does not fit into the outer corner side of the lens frame 43 of the eyeglass frame 42.
[0071] Then, as shown by the imaginary lines in FIG. 5, the lens 44 on the other side is pressed by the lens pressing pushers 71, . . . of the pusher device 7, and fitted into the lens frame 43 of the eyeglass frame 42 (step S13).
[0072] At this time, when a control signal is sent from the control unit to the pusher device 7, first, the actuator 11 is driven, the slide member 721 slides on the guide rail 73, the pusher support body 72 moves forward, and the pressing portion 71a of the lens pressing pusher 71, ... is positioned above the lens 44 on the other side.
[0073] Then, the electric motor 74 is driven to lower the lifting member 722, and the inner corner of the other lens 44 is pressed by the opposing lens pressing pushers 71, 71 positioned on the inner corner of the eye side.
[0074] As a result, the pressed lens 44 on the other side widens the area from the inner corner of the lens frame 43 with a small amount of deformation to the outer corner of the lens frame 43 with a large amount of deformation.
[0075] Subsequently, the electric motor 74 is driven to lower the lifting member 722, and the outer corner of the other lens 44 is pressed by the opposing lens pressing pushers 71, 71 positioned on the outer corner of the eye side.
[0076] As a result, the pressed lens 44 on the other side fits into the lens frame 43 of the eyeglass frame 42.
[0077] The position of the pressing portion 71a of the lens pressing pusher 71, . . . before pressing can be finely adjusted by driving the electric motor 75 to move it in the above-mentioned swing direction.
[0078] The control unit also controls the drive of the lens pressing pushers 71, . . . with a pushing amount according to the measured thickness of the lens 44 on the other side.
[0079] After the other lens 44 is fitted into the lens frame 43 of the eyeglass frame 42, the electric motor 74 is driven to raise the lifting member 722, and the actuator 11 is driven to cause the slide member 721 to slide on the guide rail 73, so that the pusher support 72 moves backward and is retracted.
[0080] Furthermore, the actuator 12 is driven, and the four pusher supports 72 move laterally, preparing for the next operation of fitting the eyeglass lenses.
[0081] The completed eyeglasses with the lenses 44 fitted on both sides are then carried by gripping the left and right ear hooks 41 with the gripping parts 35a, 35a of the robot arm 3, and placed on the tray 8 (step S14).
[0082] Although the completed eyeglasses are placed on the tray 8, the present invention is not limited to this and they may be placed on a belt conveyor or the like that flows to a collection point or the like.
[0083] Next, the effects of the automatic eyeglass lens fitting device 1 according to this embodiment will be described.
[0084] With the automatic eyeglass lens fitting device 1 configured as described above, the task of fitting the lenses 44 into the lens case 43 of the eyeglass frame 42 can be automated, rather than performed manually. This allows factories and the like to achieve full automation, making it possible to build production lines that do not rely on human labor. Furthermore, in stores such as eyeglass retailers, eyeglass assembly can be automated, allowing the time spent on assembly to be used to serve customers.
[0085] Furthermore, with the automatic eyeglass lens fitting device 1 configured as described above, the inner corner side of the lens 44 is pressed with the lens pressing pushers 71, 71 positioned at the inner corner side, so that the inner corner side of the lens 44 is fitted into the inner corner side of the lens rim 43 of the eyeglass frame 42 with a small amount of deformation, while the outer corner side of the lens rim 43 of the eyeglass frame 42 with a large amount of deformation is spread, and the lens 44 can be fitted by pressing the outer corner side of the lens 44 with the lens pressing pushers 71, 71 positioned at the outer corner side. This makes it easy to fit the lens 44 into the lens rim 43 of the eyeglass frame 42.
[0086] Furthermore, according to the automatic eyeglass lens fitting device 1 configured as described above, the robot arm 3 can automatically transport eyeglass frames 42 located at a distant location such as a stocker 9 so as to fit them into the grooves 21 of the eyeglass frame receiving molds 2.
[0087] Furthermore, with the automatic eyeglass lens fitting device 1 configured as described above, the position and angle of the eyeglass frame 42 are corrected to predetermined values using the detected correction value, and the eyeglass frame 42 is placed in an accurate positional relationship with respect to the eyeglass frame holder 2 and fitted into the groove 21. This allows the eyeglass frame 42 to be securely fitted into the groove 21 of the eyeglass frame holder 2.
[0088] Furthermore, according to the automatic eyeglass lens fitting device 1 configured as described above, the robot arm 3 can automatically transport lenses 44 located at a distant location such as on a tray 8 in order to set them in the lens frames 43 of the eyeglass frames 42.
[0089] Furthermore, with the automatic eyeglass lens fitting device 1 configured as described above, the position and angle of the lens 44 are corrected to predetermined values using the detected correction value, and the lens 44 is placed and set in an accurate positional relationship with the lens rim 43 of the eyeglass frame 42. This allows the lens 44 to be placed and fitted into the lens rim 43 of the eyeglass frame 42 without shifting.
[0090] Furthermore, according to the automatic eyeglass lens fitting device 1 configured as described above, the lens 44 is fitted into the lens frame 43 of the eyeglass frame 42 after the inner corner of the lens 44 has been fitted into the inner corner groove portion 43a of the lens frame 43 of the eyeglass frame 42, so that the lens 44 can be easily fitted into the lens frame 43 of the eyeglass frame 42 by the pressure applied by the lens pressing pushers 71, ...
[0091] Furthermore, according to the automatic eyeglass lens fitting device 1 configured as described above, the control unit controls the drive of the lens pressing pushers 71, etc., with a pushing amount corresponding to the thickness of the lens 44, so that lenses 44 of various thicknesses can be fitted into the lens frame 43 of the eyeglass frame 42 with high precision.
[0092] Furthermore, with the automatic eyeglass lens fitting device 1 configured as described above, when the lens 44 having shavings and the like attached thereto after being cut in a factory or the like is transported by the robot arm 3, the shavings and the like can be washed away by washing with water in the water tank 5 as a water washing means, and the moisture can be blown away by drying with air blower 6 as a drying means, which is an efficient way of automating the process.
[0093] Furthermore, according to the automatic eyeglass lens fitting device 1 configured as described above, the robot arm 3 is equipped with arm portions 35 and 36 and can carry both the eyeglass frame 42 and the lenses 44, so there is no need to use two robot arms, and therefore the device can be implemented at a lower cost.
[0094] The embodiment described above is an example of the present invention, and it goes without saying that the present invention is not limited to the above embodiment. In other words, the specific configurations and specific procedures of the above embodiment can be variously modified without departing from the spirit of the present invention.
