[Prior art]
Generally, in a spectacles store, a spectacle lens processing machine for polishing the contour of the spectacle lens in order to match the spectacle lens to the shape of the spectacle frame is installed. Since the optical synthetic resin will damage the surface of the product if it is held by a metal member, conventionally, a pair of suction cups made of synthetic resin such as synthetic rubber are attached to both sides of the eyeglass lens so as to be in close contact with each other, The spectacle lens is fixed to the spectacle lens processing machine by sandwiching the spectacle lens from outside the suction cup with the lens holder.
[0003]
In addition, if the pair of suction cups made of synthetic resin such as synthetic rubber alone cannot fix the eyeglass lens firmly, a double-sided adhesive tape is used as an auxiliary means between the eyeglass lens and the suction cup. Measures were taken to increase the adhesion by intervening.
[0004]
[Problems to be solved by the invention]
However, the above-described method of processing an eyeglass lens is effective for conventional optical glass and optical synthetic resin, and the suction cup made of synthetic resin such as synthetic rubber holds the eyeglass lens firmly. In the case of optical glass or optical synthetic resin with a water-repellent or oil-repellent surface treatment, which has been attracting attention recently, although there was no problem, the affinity between the synthetic resin such as synthetic rubber and the lens surface is high. Since the lens is extremely small, the lens tends to slip on the holding surface of the suction cup, and there is a problem that the lens cannot be processed while being held.
[0005]
Furthermore, in the case of these water-repellent or oil-repellent spectacle lenses, the double-sided adhesive tape also has no adhesive force and is easily peeled off, so that the conventional auxiliary means cannot provide any effect. there were.
[0006]
For this reason, with a conventional spectacle lens, a simple spectacle lens processing machine installed at a spectacle store can sufficiently cope with the problem, and provide prompt services for spectacle lens processing to customers. Despite this, these water-repellent or oil-repellent spectacle lenses cannot be polished around the lens except at the factory of the lens manufacturer. There was a problem that prompt service of processing could not be provided. In addition, there is a problem in that extra processing costs at a lens manufacturer's factory are required, which causes an increase in eyeglass costs.
[0007]
The present invention has been made in view of the above-mentioned problems and problems, and a lens for a spectacle lens in which a peripheral portion of a water-repellent or oil-repellent spectacle lens is polished by a spectacle lens processing machine and processed into the shape of a spectacle frame. In the processing method, a water-repellent or oil-repellent spectacle lens is provided by increasing a grip force between a clamp member provided in the spectacle lens processing machine and the spectacle lens. An object of the present invention is to provide a method or a machine for processing a spectacle lens that can be held in a lens.

[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing a configuration of a spectacle lens processing machine 20 to which a spectacle lens processing method 10 (FIG. 4) according to an embodiment of the present invention is applied, and FIG. 2 is an embodiment of the present invention. 1 is a perspective view showing a state in which a clamp member 2 is mounted on a spectacle lens 1 by a spectacle lens processing method 10 according to FIG. FIG. 3 is a sectional view of FIG.
[0018]
Referring to FIG. 1, a method 10 for processing a spectacle lens according to an embodiment of the present invention polishes a water-repellent or oil-repellent spectacle lens 1 at a peripheral portion 1a into a shape of an unillustrated spectacle frame. This is a method for processing a spectacle lens to be processed, which is applied to a spectacle lens processing machine 20 shown in which the spectacle lens 1 is held and processed by a holder 21.
[0019]
The water-repellent or oil-repellent spectacle lens 1 is obtained by treating a surface of a conventional spectacle lens 1 such as optical glass or optical synthetic resin with a treating agent comprising an organosilane compound or a partial hydrolyzate thereof, or an organosilicon compound. In addition to water and oil repellency, it has anti-fouling properties, such as being free of dust, and is resistant to scratches on the surface, allowing the lens to be kept in a clear state at all times. Clean and luxurious.
[0020]
In such a water-repellent or oil-repellent spectacle lens 1, the affinity between a synthetic resin member such as synthetic rubber and the lens surface is extremely small, and the spectacle lens 1 is clamped using a synthetic resin member such as synthetic rubber. It is extremely slippery on the holding surface even when trying to hold. Also, the double-sided adhesive tape has no adhesive strength and is easily peeled off. For this reason, in FIG. 2 and FIG. 3, the pair of clamp members 2 made of synthetic resin such as synthetic rubber are attached to both sides of the spectacle lens 1 in a state where the adhesive 3 is not provided, that is, in close contact with each other. In the conventional method of sandwiching the spectacle lens 1 from outside the lens 2 with the lens holder 21 or providing a double-sided adhesive tape between the spectacle lens 1 and the clamp member 2, the holding of the spectacle lens processing machine 20 is performed. The eyeglass lens 1 cannot be securely held by the tool 21.
[0021]
The spectacle lens processing machine 20 has a holder 21 for holding the spectacle lens 1 from both directions, and grinds a peripheral portion 1a of the spectacle lens 1 held by the holder 21 with a disc-shaped grindstone 21a. This is a model in which the spectacle lens 1 corresponds to the shape of a spectacle frame (not shown), and is installed in a general spectacle store.
[0022]
In the case of the spectacle lens 1 having neither water repellency nor oil repellency, the spectacle lens processing machine 20 includes a pair of clamp members 2 made of synthetic resin such as synthetic rubber on both surfaces of the spectacle lens 1 as a conventional method. Are attached in close contact with each other, and the spectacle lens 1 is sandwiched by the lens holder 21 from the outside of the clamp member 2, or a double-sided adhesive tape is provided between the spectacle lens 1 and the clamp member 2, The holder 21 can sufficiently hold the spectacle lens 1.
[0023]
However, in the case of the spectacle lens 1 which has been subjected to a water-repellent or oil-repellent surface treatment, the spectacle lens 1 is easily slipped on the holding surface of the clamp member 2 as described above, Cannot be processed.
[0024]
With reference to FIGS. 2 and 3, the eyeglass lens processing method 10 increases the gripping force of the lens holder 21 with respect to the water-repellent or oil-repellent eyeglass lens 1 to increase the water repellency or oil repellency. Is a processing method for ensuring that the spectacle lens 1 of the present invention can be held by the lens holder 21 of the spectacle lens processing machine 20. The water-repellent or oil-repellent spectacle lens 1 has both surfaces 1b, 1c. The spectacle lens 1 is elastically clamped from above the adhesive 3 applied to the lens by the elastic clamping member 2 and the spectacle lens 1 is attached to the spectacle lens 1. The lens holder 21 of the processing machine 20 (FIG. 1) holds the lens 1 and the eyeglass lens 1 is polished in this state.
[0025]
In the present embodiment, as the adhesive 3 having a characteristic that it is hard to peel off from the lens, a rubber adhesive composed of 40% of synthetic rubber and 60% of trichloroethane organic solvent is used. ing. This rubber-based adhesive cannot be wetted on the surface because other adhesives do not have affinity for the water-repellent or oil-repellent spectacle lens 1, or easily peels off even if it can be applied. Therefore, it has a large property that cannot be obtained with other adhesives, in particular, it is difficult to peel off from the spectacle lens 1. Further, after the processing of the spectacle lens 1 is completed, it is possible to completely remove the spectacle lens 1 from the spectacle lens 1 without using a solvent or the like. Since it has the property that it does not remain on the surfaces 1b and 1c of the lens 1, the eyeglass lens 1 can be processed without impairing the performance of the product.
[0026]
Next, the operation of the eyeglass lens processing method 10 according to the embodiment of the present invention will be described with reference to FIGS. FIG. 4 is a flowchart illustrating a method 10 for processing a spectacle lens according to an embodiment of the present invention. FIG. 5 is a perspective view showing the manner in which the spectacle lens 1 is held by the spectacle lens processing machine 20.
[0027]
Referring to FIG. 4, a method 10 for processing a spectacle lens according to an embodiment of the present invention first includes a step S1, as shown in FIG. The mold lens 4 corresponding to the spectacle frame is attached to the spectacle lens processing machine 20.
[0028]
Next, in step S2, the lever 21b is lowered to cover the mold lens 4 from the outside, and is securely attached to the eyeglass lens processing machine 20.
[0029]
In step S3, as shown in FIGS. 2 and 3, a rubber-based adhesive is applied to both surfaces 1b and 1c of the water-repellent or oil-repellent spectacle lens 1 as the adhesive 3.
[0030]
Then, in step S4, the adhesive 3 applied to the lens is left for a while until it dries.
[0031]
Thereafter, in step S5, it is confirmed that the adhesive 3 applied to the lens has been dried to a state where it does not adhere to the holding surface of the clamp member 2.
[0032]
Next, when it is confirmed that the adhesive 3 has dried, in step S6, the eyeglass lens 1 is elastically held by the clamp member 2 from above the adhesive 3 applied to the lens.
[0033]
Then, in step S7, as shown in FIG. 5, the handle is engaged with each of the fittings 2a attached to the back surface of the clamp member 2 and the fittings 21c and 21d attached to the holder 21. The eyeglass lens 1 is rotated by rotating the eyeglass lens 21e to reduce the distance between the locking hardware 21c and 21d, and pressing the two sides 1b and 1c of the eyeglass lens 1 between the locking hardware 21c and 21d. Is held by the lens holder 21.
[0034]
In step S8, as shown in FIG. 1, the grindstone 21a is rotated to start the polishing of the spectacle lens 1. At this time, when the contact 21f moves so as to palpate the contour of the mold lens 4, the grindstone 21a connected to the contact 21f moves the peripheral portion 1a of the spectacle lens 1 according to the contour of the mold lens 4. The eyeglass lens 1 is polished and processed.
[0035]
As described above, the adhesive 3 is applied to both surfaces 1 b and 1 c of the water-repellent or oil-repellent spectacle lens 1, thereby increasing the gripping force of the clamp member 2 with respect to the spectacle lens 1. The lens holder 1 of the eyeglass lens processing machine 20 can reliably hold the lens 1, and the eyeglass lens 1 can be polished in this state.
[0036]
As described above, according to the eyeglass lens processing method 10 according to the embodiment of the present invention, the adhesive 3 is applied to both surfaces 1b and 1c of the water-repellent or oil-repellent eyeglass lens 1, and the elasticity is increased. The spectacle lens 1 is elastically clamped from above the adhesive 3 applied to the lens by the clamp member 2 having the property, and the spectacle lens 1 is attached to the lens holder 21 of the spectacle lens processing machine 20. The eyeglass lens 1 is polished in this state, so that the gripping force between the lens holder 21 provided in the eyeglass lens processing machine 20 and the eyeglass lens 1 can be increased. As a result, the water-repellent or oil-repellent spectacle lens 1 can be reliably held by the lens holder 21 of the spectacle lens processing machine 20.
[0037]
Further, according to the processing method of the present embodiment, since a rubber-based adhesive is used as the adhesive 3, the rubber-based adhesive may be peeled off even though other adhesives may be peeled off. There is an effect that cannot be obtained with other adhesives that are difficult to perform.
[0038]
Further, according to the processing method of the present embodiment, even in the case of the synthetic resin eyeglass lens 1 in which the holding pressure cannot be increased due to the limitation of the material strength, the holding of the eyeglass lens processing machine 20 is ensured. Since the lens can be held by the tool 21, the precision of lens processing is not impaired. Further, since the present invention is applied to the synthetic resin eyeglass lens 1 which can be mass-produced and is distributed in large quantities in the market, the economic effect is great.
[0039]
Further, according to the processing method of the present embodiment, since the hardness of the material is large, not only a long time is required for polishing, but also the pressure of the grindstone on the spectacle lens 1 needs to be increased. Even in the case of the lens 1, since the lens can be reliably held by the holder 21 of the eyeglass lens processing machine 20 against the pressure of the grindstone, the accuracy of the lens processing is not impaired.
[0040]
For this reason, even for such a water-repellent or oil-repellent spectacle lens 1, it is not particularly necessary to perform polishing at a factory of a lens maker, and a simple spectacle lens processing installed in a conventional spectacle store is not required. The machine 20 can sufficiently cope with the situation, and can provide a prompt service for processing the eyeglass lens 1 to the customer.
[0041]
Further, since no extra processing cost is required at the factory of the lens maker, the cost of eyeglasses does not increase.
[0042]

It is hard to peel off from the water-repellent or oil-repellent spectacle lens 1, and after the lens processing is completed, it can be easily peeled off from the lens without using a solvent or the like. Other adhesives can be used as long as they do not leave traces on the lens surfaces 1b and 1c.
[0049]
The spectacle lens processing machine 20 does not necessarily need to be of the type in which the mold lens 4 is attached to the spectacle lens processing machine 20, as shown in the figure. Various design changes are possible, such as a spectacle lens processing machine of a type that processes the spectacle lens 1 in a controlled manner.
[0050]
Further, the present invention is not limited to the method of polishing the spectacle lens 1 by rotating the grindstone 2a, but may be the method of polishing the peripheral portion 1a of the spectacle lens 1 with a tool such as a metal vise.
