Description

Large-diameter optical lens polishing machine equipped with measuring tower {THE GRINGING APPARATUS FOR OPTICS LENS HAVING MEASUREMENT TOWER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing optical lenses, and more particularly, to an apparatus for polishing a first-cut abrasive object with a large-diameter optical lens to obtain a large-diameter optical lens that cannot be produced by an injection molding method or the like.

Optical lenses are widely used in cell phones, microscopes, astronomical telescopes, and satellites. They vary in size and function.

In addition, it is manufactured from various materials according to the use and function from plastic material to glass or special optical material.

In the case of plastic lenses used in mobile phones, the small size and high precision are not required, so mass production is possible through injection molding.

However, large diameter optical lenses used for astronomical telescopes and satellites are produced through cutting and polishing because mass production is impossible due to their size and precision.

That is, a large diameter optical lens was obtained by manually cutting a cutting object into an optical lens shape through a CNC machine tool, and then manually grinding to obtain high precision.

However, large diameter optical lenses used for astronomical telescopes and satellites are difficult to handle because they are mostly heavy and fragile materials.

The reason why polishing with a large-diameter optical lens is difficult is that the parabolic surface is so large that it is difficult to secure overall uniformity.

Another difficulty in producing large-diameter optical lenses through polishing has arisen in the measurement of polishing conditions.

In other words, because polishing is performed manually, it is necessary to stop polishing and check the polishing state after a certain amount of polishing. The measurement work is not only an easy task but also requires a long time to handle heavy and large polishing objects carefully. It was not very good workability because it requires several measurements until completion.

On the other hand, there has been a great difficulty in the production of large-diameter optical lenses having a non-focal surface.

The parabolic surface serves to make the light coming from the focal point into a completely parallel beam as shown in FIG. 1.

This parallel beam is a phenomenon that occurs when the light source is far away, like starlight. When the parallel beam is viewed in full view, the parallel beam is obtained.

Therefore, the paraboloid serves to generate starlight when evaluating the full circle on the ground.

However, in order to make a parallel beam, the light source must be located on the parabolic axis, so the light passing back near the light source among the parallel beams coming out of the parabolic surface is blocked by the light source and cannot be used.

To avoid this, a part of the parabolic surface is used as shown in FIG. 2, and a part of the parabolic surface used in this way is called a non-parabolic surface.

2 shows the non-parabolic paraboloid in the entire parabolic plane of the optical lens.

In order to produce an optical lens having such a non-arranged parabolic surface, conventionally, a method of securing a large object to be polished to polish a larger parabolic surface and then cutting out a necessary portion thereof.

 However, the method as described above has a problem that the larger the size of the stockpile surface, the larger the object to be polished, the higher the material cost and the polishing cost as well as the limitation in its operation.

The patent application No. 10-2008-0125219 (filed Dec. 10, 2008) of the applicant of the present invention was devised to solve this problem.

However, even in the above technique, the measurement operation of the processing state is required in the polishing process of the optical lens, and inconvenience has arisen in the measurement operation.

The present invention is to solve the above problems, more specifically, to polish the polishing object precisely with a large diameter optical lens with a large diameter, can greatly reduce the number of times of measurement of the polishing state, the operation of the polishing state is quick and An object of the present invention is to provide a large-diameter optical lens polishing apparatus that is easily made.

Another object of the present invention is to provide an optical lens polishing apparatus capable of repeatedly producing not only a spherical optical lens but also an aspherical optical lens having a non-parallel object surface through one device.

In the present invention, the turntable on which the polishing object is placed is rotated, and the polishing tool is movable up, down, left, and right while maintaining the state of contact with the polishing object at a constant pressure, but the right side is rotated and the left side is upper surface of the turntable. The tool to be moved in the downward direction and in a moving manner along the body so that the polishing tool can be rotated smoothly while drawing the circumference.

In addition, a central processing unit for automatically controlling the rotation of the turntable, the rotation of the polishing tool, and the movement of the polishing tool based on the input data, and having a data input device capable of inputting data into the central processing unit, Inputting data for polishing with a large-diameter optical lens of a desired shape automatically grinds the object to be polished.

In addition, a measurement tower equipped with a measuring device capable of measuring the polishing state of the polishing object is placed on the top of the turntable so that the polishing operation can be quickly and easily performed.

That is, the rotation of the turntable, the rotation of the polishing tool, and the movement of the polishing tool are automatically controlled according to the data input to the central processing unit, so that the polishing object can be precisely polished with a large diameter optical lens and the polishing state can be frequently measured. It is not necessary.

In addition, the grinding | polishing state measurement is made to be made quickly and easily by a measuring tower.

The optical lens polishing apparatus of the present invention has a base frame having various first components and a first upper frame and a second upper frame installed to correspond to each other.

Further, the object to be polished is settled and has a rotatable turntable installed in the base frame.

Moreover, it has a turntable rotating means for rotating a turntable using a motor.

In addition, one end is coupled to the rotation axis located on the first upper frame and the other end is connected to the second upper frame has a tool moving body capable of rotating in the horizontal direction about the rotation axis.

In addition, the tool moving body has a tool moving body rotating means for causing the other end of the tool moving body to move along the second upper frame so that the tool moving body is rotated about the rotation axis as a whole.

Moreover, it has a tool mounting body attached to the lower part of a tool moving body.

Moreover, it has a tool moving means which can move a tool mounting body to the longitudinal direction of a tool moving body.

In addition, a measuring device capable of measuring the polishing state of the object to be polished is provided, and has a measuring tower located above the turntable.

The apparatus further includes a data input device capable of inputting data relating to the operation of the turntable rotating means, the tool moving body rotating means, and the tool moving means to the central processing unit.

In the optical lens polishing apparatus of the present invention, the polishing tool is moved up, down, left, and right in a state in which the polishing tool is in contact with the polishing object, while the right side rotates and the left side moves along the upper and lower tool moving bodies. It is moved in a moving manner and equipped with a central processing unit that automatically controls the rotation of the turntable, the rotation of the polishing tool, and the movement of the polishing tool based on the input data. The object is automatically polished and polished with a precision optical lens.

That is, the rotation of the turntable, the rotation of the polishing tool, and the movement of the polishing tool are automatically controlled based on the data input to the central processing unit, thereby precisely polishing the object to be polished by a large diameter optical lens with a large diameter. Polishing automatically means that the polishing conditions do not need to be measured frequently.

In addition, the measurement tower equipped with the measuring equipment is located on the top of the turntable, and the measurement of the polishing state is made through this measuring tower, so that the measurement of the polishing state is quick and easy.

Hereinafter, the technical spirit of the present invention will be described in more detail with reference to the accompanying drawings.

It is to be understood, however, that the appended drawings illustrate only typical embodiments of the present invention and are not to be considered as limiting the scope of the invention.

The present invention relates to an apparatus for polishing a polishing object 1 processed into an optical lens shape by a CNC machine tool or the like with a precise large-diameter optical lens.

Therefore, the polishing apparatus of the present invention also secures a space that can be processed while being rotated while the polishing object to be polished by the optical lens is placed, and has a base frame 10 on which various components are installed.

In addition, the polishing object 1 has a turntable 20 in which it is placed and fixed, and the turntable 20 is installed in the base frame 10.

Moreover, it has the table rotating means 60 which rotates the said turntable 20 using a motor.

In addition, the present invention also has a tool mounting body 30 in which the polishing tool 2 for polishing the polishing object 1 located on the turntable 20 for polishing with an optical lens can be separated and combined.

However, the present invention has an object to solve the problems caused when polishing a large diameter optical lens with a conventional optical lens polishing apparatus.

That is, in the related art, since a large diameter optical lens is manually polished, it is very difficult to polish a large diameter optical lens, and there is a problem that frequent measurement of the polishing state is required.

In order to solve such a problem, in the present invention, when data for cutting or polishing is input to the central processing unit, as in a typical CNC machine that performs cutting and polishing operations, the polishing tool 2 is based on the input data. By automatically moving, the polishing object 1 can be precisely polished with a large-diameter optical lens.

Accordingly, the optical lens polishing apparatus of the present invention has a central processing unit 40 that controls various components to operate based on input data as in a conventional CNC machine tool.

It also has a data input device 50 which can input data relating to the movement of various components for polishing to a desired optical lens to the central processing unit 40.

The CPU 40 corresponds to the CPU of the computer, and the data input device 50 corresponds to the keyboard, and when applied to a CNC machine tool, it may be modified and applied in various forms.

When applied to the present invention can also be applied in the same form as applied to CNC machine tools.

Since the CPU 40 and the data input device 50 are well known, detailed description thereof will be omitted in describing the present invention.

However, since the present invention is for polishing the polishing object 1 with a large-diameter optical lens, it is difficult to apply a structure of a machine tool already known.

That is, through the known structure of the CNC machine tool (structure for rotation and movement of the cutting tool for cutting) has been a lot of difficulties in polishing with a large diameter optical lens.

In addition, it has been difficult to polish precise optical lenses through the structure of the apparatus used to produce large-diameter optical lenses by hand.

The inventors of the present application have been able to precisely grind the polishing object 1 with a large-diameter optical lens after long research and effort, and have devised a structure of a polishing apparatus as shown in FIGS. 4 and 5 suitable for an automated system.

That is, while the polishing tool 2 is in contact with the polishing object 1 at a constant pressure, the surface of the polishing object 1 is moved up, down, left, and right to be polished, and the movement for polishing is performed by polishing the optical lens. It is to be suitable for.

Specifically, in the polishing apparatus of FIGS. 4 and 5, the turntable 20 is installed on the base frame 10 so as to be rotatable.

Moreover, the table rotating means 60 which rotates the turntable 20 using a motor etc. is provided.

In addition, one end is coupled to the rotation shaft 14 located on the first upper frame 11 and the other end is connected to the second upper frame 12 to rotate in the horizontal direction about the rotation shaft 14. It has a tool movement body 70 possible.

In addition, the tool moving body rotating means for causing the other end of the tool moving body 70 is moved along the second upper frame 12 so that the tool moving body 70 is generally rotated about the rotation axis 14 ( 80)

Moreover, it has the tool mounting body 30 attached to the lower part of the tool moving body 70. As shown in FIG.

In the drawing, the tool mounting body 30 can correspond to a specific point of the polishing object 1, but the pressure holding means 31 is further provided, so that the combined polishing tool 2 is connected to the pressure holding means 31. This causes the polishing object 1 to be polished by moving in a state of being pressed to the polishing object 1 at a constant pressure. (This is to enable precise polishing.)

In addition, the tool mounting body 30 has a tool moving means 90 that allows the tool mounting body 30 to selectively move in the longitudinal direction of the tool moving body 70 by using a speed reducer or the like.

The central processing unit 40 also controls the operation of the table rotating means 60, the tool moving body rotating means 80, and the tool moving means 90 based on the input data.

In addition, the data input device 50 is able to input the data for the operation of the table rotating means 60, the tool moving body rotating means 80, the tool moving means 90 to the central processing unit 40. have.

That is, the polishing tool 2 has a structure capable of smooth and precise movement in the up, down, left and right movements on the polishing object 1 for polishing by the optical lens.

In addition, when the turntable 20 is rotated and the polishing tool 2 is moved along the tool moving body 70, polishing is performed with an optical lens having a spherical parabolic surface.

In addition, when polishing is completed, it is necessary to measure the polishing state, which means that the polishing tool 2 or the means for moving the polishing tool 2 is not a problem in measuring the polishing state.

The table rotating means 60 is to rotate the turntable 20 by receiving the rotational force of the motor, the table rotating means 60 is a widely used in various machine tools, so a detailed description thereof will be omitted.

Tool moving body rotation means 80 of the components of the present invention can be implemented in various forms.

As a specific example, as shown in FIGS. 4 and 5, when the rotating shaft in which the spiral protrusion is formed is rotated by the reducer, the left side of the tool moving body 70 connected to the rotating shaft is in the upper and lower surfaces of the turntable 20. Before and after, it can be implemented so that the right side of the moving body is rotated (rotated about the rotating shaft 14) in the upper and lower direction of the surface of the turntable 20.

Rotating shafts formed with spiral projections may have triangular or square threaded projections, such as bolts, or semi-circular spiral projections, such as those commonly used under the name of 'ballscrews' (not shown).

As described above, the structure for moving the object by using the rotating shaft having the spiral protrusion is widely used in various industrial fields as well as various machine tools, and thus a detailed description thereof will be omitted.

However, when the second upper frame 12 extends in a straight line shape as shown in the accompanying drawings, the other end of the tool moving body 70 moves linearly along the second upper frame 12, and such a straight line Due to the movement, the tool moving body 70 rotates as a whole (rotation about the rotary shaft 14), so that the part connecting the tool moving body 70 and the second upper frame 11 is a tool moving body ( 70) should be able to move in the longitudinal direction.

That is, the other side of the connection element 81, one side is fixed on the second upper frame 12 is to be able to move in the longitudinal direction of the tool moving body (70).

To this end, the protrusion of the connecting element 81 may be implemented in the manner as shown in FIG. 8 so that the protrusion moves along the groove formed in the tool moving body 70.

Tool moving body rotating means 80 can be implemented by applying the method used in various machine tools in addition to the above-described structure.

The structure for separating and joining the polishing tool 2 from the tool mounting body 30, which is a component of the present invention, may be implemented in a conventional form provided in various machine tools and a form provided in a conventional optical lens polishing apparatus. have.

In addition, the pressure holding means 31 for pressing the combined polishing tool 2 to a predetermined pressure on the polishing object 1 may be implemented in a form using a spring as shown in FIG. 6.

In the pressure holding means 31 of FIG. 6, the separation tool body 32 to which the polishing object 1 is coupled receives a force by the elastic force of the spring 33 so that the polishing tool 2 is applied to the polishing object 1. It is implemented in the form of contact at a constant pressure.

The pressure holding means 31 may be implemented in the form of a pressure holding device used for various advanced equipment.

That is, it may be implemented in the form having a sensor, various pressure generators and pressure regulators.

Tool moving means (90) which is a component of the present invention can be implemented in various forms.

Like the tool moving body rotating means 80 described above, it can be implemented in the form having a rotating shaft formed with a spiral projection. (Not shown)

That is, the rotating shaft is installed along the tool moving body 70, and when the rotating shaft is rotated by the operation of the reducer, the tool mounting body 30 connected to the rotating shaft is moved along the rotating shaft.

The tool moving means 90 can also be implemented in various forms used in various machine tools in addition to the above structure.

In the structure of the apparatus as described above, it is necessary to measure the polishing state when the polishing operation to the optical lens is considerably progressed or completed. In this case, the polishing state can be measured by a method using optical interference.

In order to make this measurement work smooth, the polishing tool 2 or the means for the movement of the polishing tool 2 should not interfere with the measurement.

This is because the polishing object 1 for polishing with a large-diameter optical lens is heavy and brittle, and it is unreasonable to move the polishing object 1 from the turntable 20.

In the present invention having the above structure, the left side of the tool moving body 70 may be moved so that components such as the tool moving body 70 and the tool mounting body 30 are not positioned above the polishing object 1. have.

Therefore, even when the object to be polished 1 is fixed on the turntable 20 for polishing, the polishing operation can be smoothly performed.

However, in order to measure the polishing state by the method using the optical interference, it is desirable to implement a variety of measuring equipment so that such measuring equipment can be installed quickly and simply.

To this end, in the polishing apparatus of the present invention, the turntable 20 is rotatably embodied so that it can stand up for measurement while lying down for polishing, and the turntable 20 is laid down for polishing or set up for measurement of the polishing state. The turntable upright means 100 for rotating the turntable 20 may be further provided.

That is, the turntable 20 is to be rotated about the horizontal axis 13 by the turntable upright means 100 to stand.

The turntable upright means 100 may be implemented in various forms.

Specifically, it can be implemented in a form having a cylinder that operates by pneumatic or hydraulic pressure.

That is, the turntable 20 is erected when the cylinder shaft moves forward, and the turntable 20 is laid down when the cylinder shaft moves backward. (Not shown)

In addition, as shown in FIG. 5, the turntable 20 may be erected or laid down as the rotary shaft of the reducer 101 is connected to the reducer 101.

The above-described structure is a structure for installing various measuring equipment as necessary, and a structure for setting up a turntable.

However, by implementing the apparatus of the present invention in a form in which various measurement defenses are installed in advance, it is possible to quickly and easily measure the polishing state.

To this end, it can be implemented in the form having a measuring tower 130, which is located on the top of the turntable 20, is provided with a measuring device 131 for measuring the polishing state of the object to be processed.

The measurement tower 130 as described above may be implemented in a non-movable form, but only at a set position (a position where the measuring equipment 131 can measure the polishing state of the polishing object) only when it is moved along the rail to perform the measurement. It can also be placed.

The measuring equipment in the above description may use various types of known materials, such as a measuring apparatus using a profilometer or a laser interferometer.

However, in the initial stage of polishing to polish the basic shape of the optical lens, a profilometer is used, and in the precision machining stage to smoothly process the surface, the surface is roughened while measuring the surface roughness through a measuring equipment using a laser interferometer. (Null is measured in front of the laser interferometer in the process of smoothing the surface while polishing with an aspherical optical lens. Since such null is already known, a detailed description thereof will be omitted.)

Therefore, it is desirable to have both measuring equipment using a profilometer or a laser interferometer.

In the structure having the measurement tower 130 as described above may be implemented such that the turntable 20 is erected or laid down.

In the above-described structure of the present invention, if the polishing tool 2 to be mounted can be rotated, the polishing object 1 may be polished with an aspherical optical lens having a non-stock object surface.

That is, in the above-described structure, when the polishing tool 2 only moves along the tool moving body 70 without being rotated, and the turntable 20 is rotated at high speed, polishing is performed by using an optical lens having a spherical parabolic surface. It is possible.

In this case, there is a disadvantage in that it is not possible to produce an aspherical optical lens having a non-parallel plane.

However, in the above-described structure of the present invention, when the polishing tool 2 is rotated and then the polishing object 1 is rotated while the polishing object 1 is not rotated, the polishing tool 2 is rotated in the tool moving body. If it moves along 70, it can be grind | polished with the aspherical optical lens which has a stockpile surface.

To this end, the tool mounting body 30 of the present invention is implemented to be rotatable, and by rotating the tool mounting body 30 using a motor, the tool rotating means 110 for rotating the mounted polishing tool 2 further. It can be provided.

Of course, the central processing unit 40 allows the rotation of the polishing tool 2 through the tool rotating means 110 based on the input data.

In the present invention, the data input to the central processing unit is stored even when the polishing is finished so that when the polishing object of the same type is repeatedly polished, the stored data can be loaded and used without having to re-enter the data one by one. It is desirable to.

In the apparatus of the present invention, when the retention time for which the polishing tool 2 stays at a specific point of the polishing object 1 is long, the corresponding part is polished a lot, and when the retention time is short, the corresponding part is polished less.

Therefore, when polishing by the input data fails to obtain a large-diameter optical lens, that is, when there is a lack of polishing, the polishing tool 2 is repositioned at that portion so that only polishing at that portion is achieved. It may be.

In the present invention, the rotation axis 14 positioned on the first upper frame 11 may further include a rotation center variable stage 120 for moving in the longitudinal direction of the first upper frame (see FIG. 9).

If the rotational center of gravity variable stage 120 is further provided, various effects can be obtained, such as being able to polish with a variety of optical lenses.

Reference numeral 121 is a motor that is a component of the rotation center value variable stage 120.
