Description

Device for inspecting the surface of contact lenses

The present invention relates to a contact lens surface inspection device, and more specifically, by combining a rotational observation method with a loupe and an enlarged observation method with a microscope, it is possible to observe the entire surface of the lens to be measured under the use of a microscope. In addition, the lens to be measured can be rotated to be observed, allowing stereoscopic observation, such as using a 3D microscope, and using the microscope's illumination horizontally and adjusting the height and angle of the illumination. The present invention relates to a contact lens surface inspection device that can observe the entire surface of the lens while rotating the lens under bright light and overcome the problem of diffuse reflection on the lens surface.

In general, hard contact lenses have a size similar to that of a human pupil and are 1 to 1.5 cm in size and are transparent materials, and have been used a lot because they have the ability to solve not only myopia correction but also astigmatism, which is difficult for soft contact lenses to correct.

Since such a hard contact lens is a medical device applied to the human body, it is necessary to discriminate defects such as scratches on the lens surface before shipment of the product, whether foreign substances such as air bubbles are contained, and cracks or shape deformation of the lens edges. It will serve as a key process for quality determination in product production.

Conventional hard contact lens surface inspection includes inspection using a microscope, and inspection using a loupe under bright lighting.

In the case of using a real microscope, since the vertical illumination of the microscope, that is, light is observed on the contact lens and observed, the light on the lens surface overlaps the defect area, making it difficult to identify the defect. In addition, under the microscope, an object is enlarged to show, so there is a limitation that only a part of the lens is observed in one frame.

In addition, when using a loupe under bright lighting, the inspector observes while rotating the lens such as 45 degrees, 90 degrees, 180 degrees by rotating the contact lens while holding the contact lens in one hand and the loupe in the other. It depends on the subjective judgment of the examiner, and there is a limit that it is impossible to observe fine scratches observed only under a microscope.

In addition, the conventional inspection method as described above is observed while moving the lens, causing fluctuations in the distance between the lens and the light source for illumination, or the inspection condition of the lens is not stable due to reflection of the light source, etc. Not only does it require an operator, but even a highly skilled worker is observed through different conditions for each operator, and thus, there is a problem in that precision and reliability of inspection are deteriorated.

In addition, since inspection can be performed inefficiently, such as a duplicate inspection area or an unexamined area, a decrease in workability, such as a delay in working time, is observed in the open state. There was a possibility that the normal lens could be discarded due to misunderstanding, and since a tweezers or other tools were used to mount the contact lens to the lens holder, there were problems such as damage to the lens surface during the inspection.

As reference pictures illustrating various types of lens defects, the contact lens surface inspection apparatus according to an embodiment of the present invention includes a pedestal 10, a microscope barrel 20, and a CCD camera as illustrated in FIGS. 1 and 2. 30, a rotating reflector 40, a rotating stage 50, and a side lighting unit 60 may be configured, and the contact lens surface inspection apparatus according to one embodiment of the present invention is illustrated in FIG. As described above, the lower lighting unit 70 and the total reflection reflector 71 may be further included to implement other embodiments.

Here, the objective lens 21 and the eyepiece 22 are preferably composed of lenses of 0.5 magnification each to reduce the size of the image transmitted to the CCD camera 30 and increase the resolution. Here, when the objective lens 21 and the eyepiece 22 are smaller than 0.5 magnification, the field of view may be widened, but the image of the lens to be measured inputted to the CCD camera is too small, which may have difficulty in detecting defects. When the magnification of the lens 21 or the eyepiece 22 is greater than 0.5, the image of the lens to be measured that is input to the CCD camera is large, so the field of view is narrowed and it looks dark. It can be impossible.

The CCD camera 30 is installed on the top of the microscope barrel 20, and photographs the image observed through the eyepiece 22. Here, the image sensor mounted on the CCD camera 30 has a size of 1/1.8 to 1 inch so that the lens to be measured observed through the eyepiece 22 can be observed as a high-quality image within one frame, that is, one monitor screen. It is preferably mounted. Here, when the size of the image sensor is smaller than 1/1.8 inches, the image of the lens to be measured observed in one frame may be too small to have difficulty in detecting defects, and when the size of the image sensor is larger than 1 inch, one frame This is because it may be impossible to observe the entire lens to be measured with one monitor screen because the image of the lens to be measured is too large.

The rotating reflector 40 is installed at the bottom of the microscope tube 20, and is installed to be able to rotate 360 degrees horizontally by a reflector rotating motor 41 installed on one side of the tube as illustrated in FIGS. 4A and 4B, Tilt adjustment is installed to select whether to view the side or the top of the lens to be measured. In particular, for hard contact lenses, an optimal image can be observed when a 45-degree reflector is applied.

As illustrated in (A) and (B), the LED light source 62 is fixed and is installed to adjust the front condenser lens 63 back and forth to make parallel or diffuse light. In particular, the condensing lens 63 is the highest transmittance at 400 ~ 700nm, it is preferable to use a condensing lens having a focal length of 20nm. The side lighting unit 60 can focus and send the most light to the sample when it is parallel light, and it is easiest to discriminate defects in the lens to be measured. That is, since the parallel light reaches the lens to be measured and is diffusely reflected at a defective portion of the lens to be measured, light is increased or decreased unlike the normal lens surface, and thus it is possible to determine the presence or absence of defects by using it, and the specific incident angle of the light source This makes it easier to discriminate defects.

In addition, the side lighting portion 60 is installed to enable the rotation (or bending) by an external force is formed of a hinge structure connecting portion 64 connecting the lighting support 61 and the side lighting portion 60 as illustrated in Figure 6b It is configured to be able to adjust the irradiation angle of the light, it may be made of a plurality of side lighting units (60a-60c) that emit light having a different intensity or wavelength of light, as illustrated in Figure 6c. The plurality of side lighting units 60a-60c may be, for example, two side lighting units 60a and 60b as 6500K white side light LEDs and one side lighting unit 60c as 405nm side light LEDs. will be.

The lower lighting unit 70 is installed on the lower side of the rotating stage 50 as illustrated in FIG. 3 and is configured to irradiate parallel light horizontally toward the center from the lower side of the rotating stage 50. It is preferable that the lower illumination part 70 is configured to enable selective irradiation of parallel light or diffused light, height adjustment, and light irradiation angle like the side lighting part 60.

It is possible to adjust the height and angle of the light so that the entire surface of the lens can be observed while rotating the lens under bright light, such as when looking at a loupe, so that the problem of diffuse reflection on the lens surface can be solved.

First, in order to allow the image of the lens to be measured to be observed in one frame, i.e., one monitor, at the top end of the microscope tube 20, a large CCD camera 30 having a size of 1/1.8 to 1 inch is used. Installed, the objective lens 21 and the eyepiece 22 installed on the top and bottom of the microscope tube 20 is a lens of 0.5 magnification to increase the resolution while reducing the size of the image transmitted to the CCD camera (30). Install it alternately.

The microscope tube 20 installed as described above is vertically installed at the upper portion of the stand 10 by supporting one side by a tube support 11 fixed at the lower end of the stand 10.

In addition, a rotating reflector 40 is mounted on the lowermost portion of the microscope barrel 20 to remove diffuse reflection of light from the lens to be measured, and the light reflected from the lens to be measured is installed on the lowermost portion of the microscope barrel 20. It is made to be incident on the objective lens 21 through the reflector, and can be observed as an image on the CCD camera 30 through the eyepiece 22.

In addition, the rotational stage 50 of the circular body having a central opening hole 50a in the center is rotated under the microscope tube 20, that is, directly under the rotating reflector 40 installed at the bottom of the microscope tube 20. It is possible to install, and each of the plurality of lens holders 51 provided with a lens mounting groove 51a for placing the lens to be measured on the rotating stage 50 is supported by the holder holder 52, thereby forming a circular body. Install at a certain height apart from the bottom surface, but radially along a circular body. At this time, each lens holder 51 is disposed toward the center so that the lens mounting groove 51a is positioned above the central opening hole 50a of the circular body.

In addition, a plurality of side lighting units (60; 60a-60c) made of an LED light source 62 and a condensing lens 63 are supported on one side or both sides of the rotating stage 40 by means of the lighting support 61. It is installed on the pedestal 10 so that the height of the light source can be adjusted, but installed so that light can be irradiated horizontally with the lens holder 51. At this time, the LED light source 62 of each side lighting portion 60 is rotatably (or bent) by the hinged connection portion 64 so that the irradiation angle of light can be adjusted. In addition, the LED light source 62 of each side lighting unit 60 is fixed and allows the front condensing lens 63 to be adjusted back and forth to make parallel light or diffuse light as necessary.

In the present invention, in particular, the LED light source of the two side lighting units 60a and 60b is a white side light LED of 6500K, and the LED light source of one side lighting unit 60c uses a side light LED of 405 nm, and a condenser lens 63 ) Uses a condensing lens that has the highest transmittance from 400 to 700 nm and has a focal length of 20 nm, so that when the parallel light is irradiated and diffusely reflected in the defective part of the lens to be measured, the light will be reduced or reduced unlike the normal lens surface. And use it to determine the presence or absence of defects. In particular, if the irradiation angle of the LED light source is adjusted to a specific incident angle, defects can be more easily identified.

In addition, the lower illumination unit 70 is installed to irradiate parallel light horizontally toward the center from the lower one side of the rotating stage 50, and the total reflection reflector 71 is installed directly below the rotating stage 50 to exit from the lower illumination unit. Light is totally reflected by the total reflection mirror 71 toward the rotating stage 50 so that light is irradiated upward from the lower portion of the rotating stage 50 toward the lens holder 51 through the central opening hole 50a.

Subsequently, the lens to be measured is placed on the lens holder groove 51a formed in the lens holder 51 of the rotating stage 50, and the parallel light is irradiated from the side lighting unit 60 to the CCD camera 30 at the top of the microscope tube 20. When the image of the lens to be measured is observed through ), the image of the lens to be measured can be observed in one frame, and the rotating reflector 40 is rotated or tilted as necessary, or the rotating stage 50 is rotated. It is possible to observe while rotating the entire surface of the lens through an operation of rotating as needed. At this time, depending on the angle of the rotating reflector 40, it is possible to select whether to view the image of the lens to be measured more to the side or to look at the upper side. Especially, when observing a hard contact lens, it is optimal when a 55 degree reflector is applied. You can observe the image of.
