Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing an optical member in which a resin layer is integrally molded on the surface of a glass member.

[0002]

2. Description of the Related Art Heretofore, there has been known a method of forming a lens having an aspherical surface shape which is difficult to process only with a glass material by molding a resin layer on the surface of a glass member. A lens molded by such a method is generally called a replica lens. At the time of molding, a step of supplying the resin liquid, which is the material of the resin layer, to the glass member, the member in which the glass member and the resin layer are integrated, or the mold member is required. There is a case where it is displaced from the center of the member to be supplied or the roundness of the supplied resin liquid is deteriorated. In such a case, when the mold member and the glass member or the member in which the glass member and the resin layer are integrated are brought close to each other and the resin liquid is spread to a desired thin resin layer, the resin is displaced from the center of the glass member. It spreads and spreads out into a shape with poor roundness.

In order to solve these problems, it is necessary to accurately supply the position of the resin liquid to be supplied to the center of the member to be supplied or to improve the roundness of the resin liquid to be supplied. Even if the resin discharge port of the resin liquid supply device is precisely positioned in the center of the supply target member, it is difficult to supply the resin liquid with a desired accuracy and a desired circularity. Therefore, at present,
Even if the position of the supplied resin liquid deviates from the center of the member to be supplied or the circularity of the supplied resin liquid is poor, the method disclosed in Japanese Patent Laid-Open No.
As disclosed in No. -13902, an annular ridge or groove is formed outside the optically effective diameter of a mold member to solve the above problems when the resin liquid spreads.

[0004]

However, in the above-mentioned conventional example, even if the annular convex line or the concave groove exists outside the optically effective diameter, the light ray passing therethrough is greatly refracted, so that the photographing is performed. When used as a system lens, a ghost will occur. In addition, there is a problem that it takes time and labor to form the convex stripe or the concave groove on the mold member or the glass member.

When the above technique is not used, a resin liquid is supplied to bring the mold member and the glass member or a member in which the glass member and the resin layer are integrated into close proximity to each other until the desired resin layer thickness is reached. When pushed out, it was necessary to take measures to prevent the resin from spreading out from the center of the glass member and spreading, or the way of spreading with poor roundness.

Therefore, the present invention has been made in view of the above-mentioned problems, and an object thereof is to supply a resin liquid to be supplied without forming an unnecessary shape as an optical function to a member to be supplied. An object of the present invention is to provide a method of manufacturing an optical member in which the resin layer is supplied to the center of the glass with good circularity and the resin layer is molded into the center of the glass member with good circularity.

[0007]

In order to solve the above-mentioned problems and achieve the object, an optical member manufacturing method according to the present invention comprises a resin material disposed between a glass member and a mold member, and an active energy ray. In the manufacturing method of molding the optical member in which the resin material is fixed by irradiation of the glass member and the resin material, the active energy ray is removed after the surface charge of the mold member and / or the glass member is removed. It is characterized in that it is irradiated with and is molded.

In the method for manufacturing an optical member according to the present invention, the glass member is fixed between the glass member and the mold member by irradiating with active energy rays after the resin material is arranged between the glass member and the mold member, And a second resin portion formed by supplying a resin material and irradiating an active energy ray onto the first resin portion formed of the first resin material to form an optical member. Prior to the irradiation of the active energy ray, the surface of the mold member and / or the resin portion is removed from the electrostatic charge.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION A preferred embodiment of the present invention will be described below, but before that, an outline of the present invention will be described.

The above-mentioned glass member, a member in which a glass member and a resin layer are integrated, or a mold member is supplied with the resin liquid at the center thereof in a state of good roundness of one lump, and the resin is rounded well. In general, it is necessary to increase the positioning accuracy of the resin liquid discharge port when attempting to widen the position. However, in practice, the required accuracy may not be obtained even if the positioning accuracy of the ejection port is increased. As a cause of this, the applicant of the present application has found that the supplied resin material does not have a perfect circle and the resin spreads unevenly because the surface of the supply target member is charged. That is, when the resin contacts the supplied member, the resin liquid and the supplied member repel or attract each other, so that the supplied resin material does not become a perfect circle. Even if the resin is supplied to the center with good circularity, if the surface of the supply target member is charged and the charged state is not uniform within the plane, the resin spreads. It does not spread in a good roundness. Therefore, it is the gist of the present application to accurately supply the resin liquid to the center of the supply target member and to spread the resin with a good roundness by removing this electrostatic charge.

Static electricity is likely to be generated on the surface of the mold member during continuous molding in the step of releasing the molded product from the mold member.
This tendency is particularly pronounced when a resin having a large electric resistance (ceramic, resin, etc.) is used for the mold member. Further, even when the resin layer is molded once or a plurality of times on the glass member to form a resin layer by superimposing the resin layer on the glass member, the surface of the resin layer is not charged when the resin member is released from the mold member immediately before the molding of the resin layer. Wake up. Therefore, a step of removing the charge is provided before supplying the resin liquid to these members, and the resin liquid is accurately supplied to the center of the member to be supplied so that the resin spreads in a good roundness.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a diagram showing a schematic structure of an optical member molding apparatus of one embodiment.

In FIG. 1, reference numeral 10 denotes a substrate for holding a mold member 12 for molding the resin layer 32 and a support member 14 for supporting the glass member 30. A die member 12, a support member 14, and a chucking member 16 are arranged on the upper surface of the substrate 10. A release air cylinder 21 for vertically moving the release plate 20 connected to the support member 14 is arranged on the lower side of the substrate 10, and a chucking plate 22 connected to the chucking member 16 is provided. A chucking air cylinder 23 for moving the vertical direction is arranged.

More specifically, on the upper surface of the substrate 10, a support member 14 having a cylindrical inner peripheral surface 14a at its center is placed. A mold member 12 having an outer diameter slightly smaller than the inner diameter of 14a is inserted inside the support member 14, and the lower end surface of the mold member 12 is fixed to the substrate upper surface 10a. Therefore, the support member 14 has the inner peripheral surface 14
In the state in which a is guided by the mold member 12, it can slide with respect to the mold member 12 and the substrate 10 in the direction along the center line axis of the mold member 12 (vertical direction in the drawing).

Further, between the outer peripheral surface 14b and the inner peripheral surface 14a of the support member 14, there is formed a cylindrical space portion 15 which opens vertically upward, and the space portion 15 has a substantially cylindrical shape. The chucking member 16 is mounted with the inner peripheral surface of the lower fitting portion 16a fitted to the outer peripheral surface 14c of the space 15 of the support member 14. The chucking member 16 is along the central axis of the die member 12 relative to the support member 14 with the fitting portion 16a being guided by the outer peripheral surface 14c of the space 15 of the support member 14. It is slidable in the direction (vertical direction in the figure).

The chucking member 16 is an integral member composed of a cylindrical lower portion having an inner peripheral surface 16a and four arm portions 16b having a width of 5 mm.
6b stands upright from the lower cylindrical portion at equal intervals in the circumferential direction. Since the arm portion 16b is made thinner than the lower cylindrical portion, it is possible to bend inward and outward due to the elasticity of the material forming the chucking member 16. A chucking surface 16c for chucking and positioning the outer peripheral surface of the glass member 30, which will be described later, is provided at the tip of the arm portion 16b.

A protrusion 16d is provided at an intermediate portion of the arm 16b.
And a projection 16e is formed at the tip of the projection 16d. The projection 16d abuts on the cam surface 14d formed in the space 15 of the support member 14, and the projection 17e is formed.
Contacts the slope 14e formed at the upper end of the space 15 of the support member 14.

Therefore, by sliding the chucking member 16 vertically with respect to the support member 14,
The four arm portions 16b can move along the cam surface 14d and the inclined surface 14e to open and close the chucking surface 16c. That is, the glass member 30 is chucked and released by sliding the chucking member 16 in the vertical direction.

On the other hand, on the lower side of the substrate 10, a release plate 20 for vertically moving the support member 14 with respect to the mold member 12 and the substrate 10 is pushed up by the push-up rods 24A, 24B ,.
The release air cylinder 21 is fixed to the support member 14 via 24C (24C is not shown), and the cylinder rod 21a thereof is fixed to the release plate 20. Further, the chucking plate 22 for moving the chucking member 16 in the vertical direction with respect to the support member 14 includes connection rods 26A, 26B, 26C (2
6C is fixed to the chucking member 16 via (not shown), the chucking air cylinder 23 is fixed to the release plate 20, and the upper surface of the cylinder rod 23e is
A chucking plate 22 is attached.

Between the lower surface of the supporting member 14 and the upper surface of the chucking plate 22, connecting rods 26A, 26B,
The compression spring 27A, which is loosely fitted to the outer peripheral surface of 26C,
27B and 27C (only 27C is not shown) are arranged, whereby the chucking plate 22, that is, the chucking member 16 is urged in the direction of being pushed down against the lower surface of the support member 14.

Therefore, the chucking air cylinder 23
Is not operating, the weight of the cylinder rod 23b, the chucking plate 22 and the like and the compression spring 27A,
By the urging force of 27B and 27C, the chucking member 16
The four claw portions 16c are closed, and the outer peripheral surface of the glass member 30 is chucked by the four chucking surfaces 16c. In this state, the glass member 30 is held by the chucking member 16 in a state where the position of the optical axis thereof is exactly aligned with the center of the molding surface 12b of the mold member 12. When the chucking air cylinder 23 is operating, the chucking plate 22 is pushed up and the connecting rods 26A, 26B,
The chucking member 16 is pushed upward through 26C. As a result, the chucking surface 16c
Is in the open state as shown in FIG. 2, and the chucking is released.

On the other hand, the lower surface of the substrate 10 and the release plate 20
Between the upper surfaces of the compression springs 25A, 25B, 2 while being loosely fitted to the outer peripheral surfaces of the push-up rods 24A, 24B, 24C.
5C (only 25C is not shown) is arranged so that the release plate 20, that is, the support member 14 is urged in a direction to be pushed down against the lower surface of the substrate 10, that is, the mold member 12.

Therefore, when the release air cylinder 21 is not operating, the weight of the cylinder rod 21a, the release plate 20 and the like and the compression springs 25A, 25B,
The lower end portion 14f of the support member 14 is in contact with the substrate 10 by the biasing force of 25C, the glass member 30 and the mold member 12 are held at a preset distance,
The resin layer 32 has an appropriate thickness. Further, by operating the release air cylinder 21, the release plate is pushed up, and the push-up rods 24A, 24B, 24C.
When the support member 14 is moved upward through the mold, the completed replica lens 33 is released from the mold member 12.

Since the molding surface 12b of the mold member 12 is processed into an aspherical shape required for the finished shape of the replica lens 33, the glass member 30 is placed on the upper end surface 14g of the support member 14. And the support member 14 and the substrate 10
The contact surface 30a of the glass member 30 in the state where
By curing the resin liquid filled in the space defined by the molding surface 12b and the molding surface 12b, the resin layer 32 in which the aspherical shape of the molding surface 12b is transferred can be formed on the surface of the glass member 30.

Above the glass member 30, a supply device 40 for supplying a resin liquid, an irradiation device 42 for irradiating active energy rays, and a blower type static eliminator for static erasing the surface of the mold member 12. 44 are arranged and configured to be movable by the respective moving mechanisms 41, 43, 45.

Next, the procedure for molding the replica lens by using the molding apparatus configured as described above will be described.

The glass member 30 is a polishing lens made of optical glass and is conveyed to the molding apparatus shown in FIG. Assuming that the mold member 12 is formed by processing a polymer material or the like and continuously forms the replica lens, the replica lens is released from the mold member 12 when the replica lens is molded immediately before. The molding surface 1 of the mold member 12
2b is strongly charged.

Therefore, the static eliminator 44 is moved to above the mold member 12, and static eliminator is carried out for 3 seconds to eliminate static charge on the molding surface 12b.

In this embodiment, a blast type static eliminator WINSTAT T which uses corona discharge for static erasing.
Although ype BF-3 (manufactured by Shishido Electrostatic Co., Ltd.) is used, the effect does not change even if the charge is removed by using any device.

After that, the static eliminator 44 is retracted from above the mold member 12, and the resin liquid supply nozzle 40a of the resin liquid supply device 40 is located at the center of the mold member 12 and above the molding surface 12b.
Accurate positioning is performed so as to maintain a distance of mm, and a fixed amount of the resin liquid is discharged in advance.

At this time, the resin liquid is a UV-curable urethane acrylate resin, and the resin supply device 40 is MX.
-9000E (manufactured by Musashi Engineering Co., Ltd.) can be used to eject to the center of the mold member 12 with good roundness.

Next, as shown in FIG. 2, the chucking air cylinder 23 is operated to bring the chucking member 16 into a non-chucking state, and the release air cylinder 21 is operated to support the mold member 12 against the supporting member. Raise 14

Next, the glass member 30 is placed on the upper end surface 14g of the support member 14 with the bonding surface 30a facing downward. At this time, the bonding surface 3 between the resin liquid on the mold member 12 and the glass member 30
No contact with 0a. It should be noted that the bonding surface 30a of the glass member 30 is preliminarily destaticized by a destaticizing device. Then, the operation of the chucking air cylinder 23 is released to bring the chucking member 16 into the chucking state. As a result, the glass member 30 is positioned with respect to the mold member 12 so that the optical axis center of the glass member 30 coincides with the optical axis center of the molding surface 12b.
And adjust the air pressure to the release air cylinder 21,
By lowering the support member 14 with respect to the mold member 12 by 1 mm per second, the resin liquid comes into contact with the glass member 30, and subsequently the resin liquid is spread on the molding surface 12b and the bonding surface 30a with good circularity. At this time, the molding surface 12b and the bonding surface 30a have already been formed.
Since the electricity has been removed, the phenomenon that the resin liquid spreads while deforming into a distorted shape does not occur.

With the support member 14 and the substrate 10 in contact with each other, the glass member 30 and the mold member 12 are positioned at a preset distance, and the resin liquid is spread out, the ultraviolet irradiation device 42 is moved to the glass member 30. To move on. And
As shown in FIG. 1, ultraviolet rays are applied to the resin layer 32 through the glass member 30 to cure the resin layer 32.

Next, the mold release air cylinder 21 is operated to push up the support member 14 against the mold member 12, whereby the resin layer 32 molded on the glass member 30 is separated from the mold member 12. Then, the chucking air cylinder 23 is operated to release the chucking,
Remove the replica lens from the molding machine.

In the above description of the molding process, it was explained that both the glass member 30 and the mold member 12 were destaticized, and the resin liquid was supplied to the mold member 12. However, the bonding surface of the glass member 30 to be molded should be described. When 30a is a concave surface, if the necessary resin liquid is supplied to the mold member because the mold member 12 is a convex surface,
Even if the charge is removed, the resin liquid moves from the center of the mold member due to gravity, and the resin liquid cannot be supplied to the center of the mold member 12 with good circularity. Therefore, the glass member 30 and the mold member 1
When both of the two are discharged, and the resin liquid is supplied to the glass member 30 having a concave surface, the resin liquid can be supplied to the center of the glass member 30 with good circularity, and the resin can be applied to the bonding surface 30a of the glass member 30 with good circularity. The layer 32 can be formed. At this time, the joint surface 3
After the resin liquid is supplied to the glass member 30 with 0a facing upward, it is necessary to turn the glass member 30 over 180 degrees so that the bonding surface 30a faces downward, and then the glass member 30 is placed on the supporting member 14 of the molding apparatus. It is necessary to appropriately adjust the reversing speed and the reversing operation acceleration so that the resin liquid is not biased.

In the above description of the molding process, the resin layer 32 is formed on the bonding surface 30a of the glass member 30 by one molding process, but the thick and thin parts of the resin layer 32 are not formed. If the difference is large, it may not be possible to form a desired surface shape by one molding process due to the difference in shrinkage amount between the thick portion and the thin portion. In that case, a forming process is performed in which a shape close to a desired surface shape is once formed, and then a further shape is formed to form a surface shape very close to the desired shape. If the molding process is performed twice in this manner, the first resin layer is formed in a state close to a desired shape in the first molding process, so that the resin layer formed in the second molding process is almost uniform. Since the resin layer has a thickness of, the surface shape that is very close to the desired shape can be obtained, which is less affected by the shrinkage ratio of the resin.

At this time, in order to mold the resin layer in two steps, the above-described molding process may be repeated twice. However, since it is necessary to make the height of the mold member 12 different between the first layer and the second layer, whether to use different mold members for the first layer and the second layer,
It is necessary to adjust the height of the mold member.

When the second layer is molded, since the first resin layer has a large electric resistance, the first resin layer is strongly charged when the mold is released during the molding of the first layer. are doing.
Further, when the mold member 12 is made of a polymer material, the surface of the mold member is also strongly charged at the time of releasing the mold during the previous molding. For this reason, the resin liquid is supplied after discharging one or both of the first resin layer and the mold member, and the second resin layer is molded on the first resin layer.

Examples and comparative examples in which several kinds of replica lenses are molded by the molding method using the above-mentioned molding apparatus will be shown below.

Since the surface of BK7 is charged during continuous molding,
The resin is supplied after the mold member is destaticized. The resin is supplied to the mold member because the mold member has a concave surface, and the nozzle position of the resin liquid supply device is positioned within 50 μm from the optical axis center of the mold member by the precision control of the moving mechanism. As shown in FIGS. 3 (a) and 3 (b), the resin liquid is supplied to the center of the mold member with good roundness, and even when the resin liquid is spread out, it is spread while maintaining the initial roundness well. . Glass member outer diameter φ
33.5, the effective diameter of the light beam is 28.8, and the outer diameter on which the resin layer is formed is 30 of the glass member because of the optical design and the lens barrel design.
If it does not fall within the range of φ32.0, the resin layer is not formed in the optically used region, or it cannot be used as an optical component because it interferes with the lens barrel component incorporating the replica lens. The defective rate of such a replica lens is 0.5%, which is a level with no problem in actual production.

The surface of BK7 is charged during continuous molding. When the resin is supplied to the mold member, the nozzle position of the resin liquid supply device is positioned within 50 μm from the center of the optical axis of the mold member by the precise control of the moving mechanism. (A), (b)
It is difficult to supply circularity to the center of the mold member as shown in FIG. If the nozzle of the resin liquid supply device is too far from the mold member to discharge the resin, it is particularly susceptible to the charging of the mold member, and it is better to discharge the resin within 1 mm from the mold member so that the nozzle is relatively closer to the center and the circularity is good. Can be discharged. Further, even in the step of spreading the resin liquid, the spreading of the resin is promoted or suppressed by the charging of the mold member, so that the circularity of the resin is deteriorated and the resin is spread. The defect rate related to the outer diameter of the resin layer was 20%, which was a problematic level in actual production.

Since the surface of Teflon is charged during continuous molding, the first layer is molded after the mold member is destaticized. The resin is supplied to the glass member because the glass member is concave, and the nozzle position of the resin liquid supply device is positioned within 50 μm from the optical axis center of the glass member by the precise control of the moving mechanism. The resin liquid is supplied to the center of the glass member with good roundness, and when reversing the glass member upside down, the reversing speed and the acceleration at the time of reversing are adjusted appropriately so that the resin does not become biased. Place it. Since the charge of the mold member has been removed, even when the resin liquid is spread out, it is spread out while maintaining a good initial roundness.

Since KN plating is used for the second layer type member, the charging is slight. However, since the surface of the first resin layer formed on the glass member is charged,
It is necessary to remove electricity as shown in.

The resin is supplied to the surface of the first resin layer formed on the concave glass member, and the nozzle position of the resin liquid supply device is controlled from the optical axis center of the glass member by the precise control of the moving mechanism. Positioned within 50 μm. The resin liquid is supplied to the center of the glass member with good roundness, and even when the resin liquid is spread out, it is spread while maintaining the initial roundness well.

Glass member outer diameter φ33.5, light beam effective diameter
Due to the optical design of φ28.6 and the lens barrel design, when the outer diameter of the resin layer formed is not within the range of φ28.8 to φ32.0 of the glass member, the resin layer is used in the optically used region. It cannot be used as an optical component because it is not formed or interferes with a lens barrel component incorporating a replica lens.
The defective rate of such a replica lens is 1.0%, which is a level with no problem in actual production.

The present invention can be applied to modifications and variations of the above embodiments without departing from the spirit of the present invention.
