1 is a conceptual perspective view showing the concept of a spectacle lens manufacturing system according to an embodiment of the present invention.

1, a spectacle lens manufacturing system 100 according to an embodiment of the present invention includes a printer 110 that generates a spectacle lens by jetting a printing material according to 3D modeling data generated by scanning a sample spectacle lens, A conveyor 120 for moving the spectacle lens, and a post-processor 130 for improving transparency by spraying abrasive particles onto the spectacle lens moved by the conveyor 120. [ More specifically, the printing material is sprayed and laminated on the printer 110 to form a spectacle lens, and the spectacle lens is moved through the conveyor 120, and the grinding particles are sprayed onto the spectacle lens, Post-treatment with a spectacle lens. The spectacle lens formed by spraying and printing the printing material on the printer 110 is in an opaque state and is subjected to grinding with abrasive grains to improve the opaque state to a transparent state. Hereinafter, each component constituting the spectacle lens manufacturing system will be described in detail.

2 is a top view of a printer and a conveyor in a spectacle lens manufacturing system according to an embodiment of the present invention. 3 is a front view of a printer and a conveyor in a spectacle lens manufacturing system according to an embodiment of the present invention. 4 is a side view of a printer and a conveyor in a spectacle lens manufacturing system according to an embodiment of the present invention.

1 to 4, the printer 110 includes a head portion 112 for receiving a printing material and ejecting the printing material through a head nozzle, a gantry portion 114 for moving the head portion 112, And a stage unit 116 in which the printing material is laminated to produce the spectacle lens.

The head unit 112 forms a spectacle lens in accordance with a curvature value obtained by scanning the sample spectacle lens while spraying a printing material as a raw material of the spectacle lens to the stage unit 116 through a head nozzle (not shown). As the printing material, a plastic resin such as acryl can be used.

Here, the head unit 112 ejects the printing material according to the 3D modeling data generated by scanning the sample spectacle lens, and scans the entire shape of the sample spectacle lens using a 3D scanner (not shown). Through the scanning, data on the overall shape and the curvature value of the sample spectacle lens are obtained. Scanning with a 3D scanner is a commonly performed task for reverse design of the product and can obtain point data expressed as points. In order to make a spectacle lens in the printer 110, 3D modeling data (3D modeling data) is required, and a correction operation is required. Specifically, the point data obtained from the 3D scanner is caded, the CAD data is converted into a STL (Stero Lithography) file, which is a standard file format of the 3D printing technology, and the 3D model is verified to be a three- STL correction software is used to check the consistency of the STL data. If there is no problem with the data in the STL format, the data is further sliced and converted into G code (path data) which is tool path data for moving the print head.

At this time, by mounting the 3D scanner on the head part 112, scanning and printing can be performed collectively. For example, three sensors may be attached to the head portion 112, the stage portion 116 may be designed to be rotatable, and the sample spectacle lens may be placed on the stage portion 116 and rotated to obtain point data .

The gantry unit 114 moves the head unit 112 and the gantry unit 114 moves the head unit 112 up and down and right and left so that the spectacle lenses according to the 3D modeling data can be laminated. The gantry unit 114 includes a gantry motor 1141 for providing a driving force, a horizontal shaft 1142 connected to the head unit 112 to move the head unit 112 on a horizontal plane, A first connecting member 1144 and a second connecting member 1145 for fixing and / or connecting the vertical axis 1143 for moving on the plane, the gantry motor 1141, the horizontal axis 1142, the vertical axis 1143, .

The stage portion 116 is a position where the printing material ejected from the head portion 112 is stacked, and is a position where the spectacle lens is generated. The spectacle lens produced in the stage portion 116 becomes opaque. Since the printing material to be jetted from the head 112 is a plastic material such as acryl, a post-treatment step such as grinding is required to improve the transparency of the spectacle lens. The stage unit 116 moves the spectacle lens to the conveyor 120 for post-processing of the spectacle lens. Specifically, the stage unit 116 includes a plate 1161 on which the ejected printing material is stacked, a stage motor 1162 that provides a driving force, a transmission shaft 1163 that transmits a driving force, A third connecting member 1164, and the like.

The conveyor 120 serves to move the spectacle lens for post-processing of the spectacle lens. 1 and 2 illustrate that the conveyor 120 is disposed in an elliptical shape. However, it should be apparent to those skilled in the art that the conveyor 120 may be disposed in other shapes such as a straight line or a circular shape.

5 is a top view of a conveyor and a post-processor in a spectacle lens manufacturing system according to an embodiment of the present invention. 6A to 6D are cross-sectional views sequentially illustrating the operation of the post-processor in the spectacle lens manufacturing system according to the embodiment of the present invention.

1, 5, and 6A to 6D, the post-processor 130 injects abrasive particles into the spectacle lens moved by the conveyor 120 to improve the transparency of the spectacle lens.

The post-processor 130 includes a particle spraying part 132 for spraying abrasive particles onto the spectacle lens L moved by the conveyor 120, a spectacle lens 132 for moving the abrasive particles by the conveyor 120 L), and an air jetting section 136 for jetting high-temperature air to the spectacle lens L onto which the water is sprayed. Here, the spray pressure of the post-processor 130 is preferably set to about 2.5 to 3 kg / cm 2.

When the opaque spectacle lens L is moved by the conveyor 120, the post-processor 130 sprays abrasive particles or the like from the upper portion of the conveyor 120 to post-process the spectacle lens L, The transparency is improved by the spectacle lens L in which the spectacle lens L is in a transparent state. For example, as shown in Fig. 5, the transparency of the spectacle lens is improved (① / ②) by spraying abrasive particles, and water and air are sprayed to clean and dry the spectacle lens ground by grinding particles (③ / ④).

Specifically, the post-treatment process is a process in which the transparency of the spectacle lens is improved by injecting the abrasive particles in the particle jetting section 132, and the spectacle lens (not shown) moving in the conveyor 120 by the spraying of the support jig 131 and the abrasive particles L can be changed between the front and the back (see Figs. 6A and 6B). Then, water is sprayed from the water spraying unit 134 to remove foreign matter such as dust, and the air is jetted from the air spraying unit 136 to dry the water (FIGS. 6C and 6D) 6d). The front and the back are changed by the support jig 131 in the water injection and air injection processes so that water and air can be sufficiently sprayed to the entire surface of the spectacle lens L. [ In order to appropriately dry the spectacle lens L by the air jetting section 136, the wind intensity can be set to about 50 to 70 m per second.

The post-processor 130 may further include a lamp unit (not shown) for irradiating ultraviolet rays. The spectacle lens L can be sterilized by irradiating ultraviolet rays from the lamp part. Such a ramp portion can be disposed near the air jet portion 136 to maximize the sterilization effect.

Therefore, through the spectacle lens manufacturing system 100 according to an embodiment of the present invention, complex spectacle lenses can be manufactured simply and inexpensively according to the 3D printing technique, as well as automated in the conveyor process, The transparency of the spectacle lens of the present invention can be improved quickly and conveniently.

7 is a flowchart of a spectacle lens manufacturing method according to an embodiment of the present invention.

Referring to FIG. 7, a spectacle lens manufacturing method according to an embodiment of the present invention includes scanning a sample spectacle lens to obtain point data (S10), CADing the point data, generating 3D modeling data (S30), and the transparency is improved by spraying abrasive particles onto the spectacle lens (S40). The manufacturing of the spectacle lens by scanning and printing and the improvement of the transparency of the spectacle lens are collectively carried out so that each personalized spectacle lens can be produced simply and inexpensively in a short time.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
