The present invention relates to a UV post-curing device dedicated to a three-dimensional printer and, more specifically, to a UV post-curing device which intensively and uniformly irradiates a UV light source onto an object produced by a photocurable resin, and has an optimal heat dissipation structure while having the best curing quality by controlling the amount of light according to the application.

Description

광량제어 및 고밀도 UV 조사구조를 갖는 3D 프린터용 UV 후경화장치.{A POST CURING DEVICE WITH ADJUSTMENT THE LIGHT AND ILLUMINATED STRUCTURE OF HIGH INTENSITY}FIELD OF THE INVENTION [0001] The present invention relates to a UV post curing apparatus for a 3D printer having a light amount control and a high density UV irradiation structure.

본 발명은 3D 프린터 전용의 UV 후경화장치에 관한 것으로, 좀 더 구체적으로 설명하면 광경화수지(Photo Polymer)로 제작된 대상물에 UV 광원을 집중적으로 균일하게 조사하고, 용도에 맞게 광량을 제어하여 최상의 경화품질을 가지면서 최적의 방열구조를 갖춘 UV 후경화장치에 관한 것이다.The present invention relates to a UV post curing apparatus dedicated to a 3D printer. More specifically, the present invention relates to a UV post curing apparatus for a 3D printer, more specifically, a UV light source is intensively and uniformly irradiated onto an object made of a photopolymer, To a UV post curing apparatus having an optimal heat dissipation structure while having the best curing quality.

과거에는 제품을 생산하기 전에 그 대상물을 보기 위하여 3D프로그램을 통해 만들어진 대상물의 데이터를 2D프린터를 사용하여 평면상에 인쇄하듯이 출력하는 방식으로 사용되었으나, 이러한 2D방식은 정확한 대상물을 파악할 수 없는 단점이 있었다.In the past, in order to view the object before the product was manufactured, the data of the object created by the 3D program was used as a method of printing on a flat surface using a 2D printer. However, such a 2D method has a disadvantage .

따라서 최근에는 대상물을 3D데이터를 이용하여 그 대상물을 3차원, 즉 X축(앞뒤)과 Y축(좌우)과 Z축(상하) 제어를 통해 입체적으로 만들어내는 3D프린터가 많이 사용되고 있다.In recent years, 3D printers are increasingly used to produce three-dimensional objects using 3D data, that is, three-dimensionally control the object through X-axis (front and back), Y-axis (left and right) and Z-axis (up and down) control.

상기 3D프린터는 3가지 출력방식이 있으며, 고체재료를 녹여서 적층하는 FDM(Fused Deposition Modeling)방식, 분말재료를 레이저를 이용하여 소결시키는 SLS(Selective Laser Sintering)방식과 액체재료를 레이저 또는 빛으로 경화시키면서 쌓아올리는 DLP(Digital Light Processing)/SLA(Stereolithography Apparatus)방식으로 되어 있다.The 3D printer has three types of output methods, including an FDM (Fused Deposition Modeling) method in which solid materials are melted and laminated, an SLS (Selective Laser Sintering) method in which a powder material is sintered using a laser, (Digital Light Processing) / SLA (Stereolithography Apparatus) method.

또한, 입체형태의 제작물의 최종 표면 처리과정에서 광경화수지 재료를 용도에 따라 사용되기도 한다.In addition, the photocurable resin material may be used depending on the application in the final surface treatment of the three-dimensional shaped product.

본 발명은 광경화수지(Photo Polymer)를 사용하는 방식의 3D 프린터로 출력되는 대상물을 경화하는 UV-A 파장대를 갖춘 후경화장치에 관한 것이다.The present invention relates to a post-curing apparatus having a UV-A wavelength band for curing an object output to a 3D printer using a photopolymer.

상기 방식의 3D프린터는 빛에 반응하여 경화되는 광경화수지가 주재료로 사용되며, 출력된 대상물이 사용 용도에 적합하게 경화되기까지 최소 24시간에서 최대 48시간의 장시간이 소요되는 단점이 있다.The 3D printer of the above type has a disadvantage in that it takes a long time of at least 24 hours to a maximum of 48 hours for curing the output object to be used for the purpose of use, and a photocurable resin which is cured in response to light is used as a main material.

즉, 출력된 대상물을 최종 목적에 맞게 사용하기 위해 너무 많은 시간이 소요되는 문제로 인해서 생산과정에서의 소요시간이 크게 발생되고, 출력된 대상물을 보완이나 수정하는 과정 등이 발생될 경우에는 대상물의 3D데이터를 수정 후 재출력하여 경화하기까지 추가적인 시간이 더 많이 소요되기 때문에 시간지연으로 인한 출력되는 대상물의 생산성이 저하되는 문제가 있는 것이다.That is, if the output time of the output object is too long to use the output object in accordance with the final purpose, the time required in the production process becomes large, and when the output object is supplemented or corrected, There is a problem that the productivity of the output object due to the time delay is lowered because additional time is required until the 3D data is corrected and output again and hardened.

따라서 최근에 출력된 대상물을 빠르게 경화시키기 위하여 UV 후경화장치를 사용하고 있는 것이다.Therefore, a UV curing device is used in order to rapidly cure the output object recently.

이러한 UV 후경화장치는 대상물을 수용하는 케이스의 내부에 자외선을 조사하는 UV LED를 장착하여 경화속도를 약 30분 안에 빠르게 경화되도록 한 것이다. Such a UV curing apparatus is provided with a UV LED for irradiating ultraviolet rays inside a case for accommodating an object so that the curing speed is rapidly cured within about 30 minutes.

그러나 이러한 UV 후경화장치는, 대상물의 액체소재에 따라 경화되는 시간이 서로 다르고, 상기 대상물의 형상 역시 3D데이터에 의해 입체적으로 이루어지면서 UV 광원이 균일하게 조사되기 어려워 완전한 경화가 이루어질 때까지 오랜 시간이 소요되고,However, such UV curing apparatuses have different curing times depending on the liquid material of the object, and since the shape of the object is also three-dimensionally formed by 3D data, the UV light source is difficult to uniformly irradiate, However,

특히 UV LED가 120도 이상의 광각을 가지고 있기 때문에 대상물과 UV LED 사이의 거리가 멀어질수록 광량이 감소하여 대상품의 경화품질을 저하시키고 광원소자의 설치 위치에 따라 대상물의 표면에 조사되지 않는 사각 위치가 형성되는 문제점이 있던 것이다.In particular, since the UV LED has a wide angle of 120 degrees or more, the amount of light decreases as the distance between the object and the UV LED decreases, thereby deteriorating the curing quality of the product. There is a problem that the position is formed.

더욱이 종래의 UV LED는 케이스 안쪽에 설치되어 장시간 사용되고, 이때 발생하는 열기가 효과적으로 외부로 배출되지 않아 UV LED의 수명이 짧아져 자주 교환해 주어야 하거나 광효율이 저하되는 문제점이 있고, 이때 발생하는 열기가 내측에 위치한 대상물에 영향을 끼쳐 변형 및 변색을 초래하는 문제점도 있었던 것이다.Further, the conventional UV LED is installed inside the case and is used for a long time, and the heat generated at this time is not effectively discharged to the outside, shortening the lifetime of the UV LED, causing frequent replacement or deterioration of light efficiency. There is a problem that it causes deformation and discoloration due to influence on the object located inside.

또한, 최근에는 3D 스캐너로 치아의 3D 데이터를 확보한 후, 이를 이용해 3D 프린터로 치과용 제작물을 만드는 방법이 제시되고 있고, 이럴 경우에는 출력된 대상물의 경화작업을 완료한 후에 구강내 사용을 위해 별도로 살균작업을 추가해야 하는 만큼 생산공정이 복잡하고 많은 시간이 소요되는 단점으로 작업의 효율성이 매우 떨어지는 문제가 있는 것이다.In recent years, a method of making a dental product using a 3D printer after acquiring 3D data of a tooth with a 3D scanner has been proposed. In this case, after the hardening of the output object is completed, There is a problem in that the efficiency of the operation is very low due to the complication of the production process and the time required for the sterilization operation separately.

따라서 본 발명은 종래의 문제점을 해결하기 위한 것으로서, 광경화수지를 사용하는 3D 프린터로 제작된 대상물 또는 최종의 표면처리를 광경화수지를 사용하는 입체 제작물을 고밀도의 광원을 균일하게 조사하여 최상의 경화품질을 확보할 수 있는 UV 후경화장치를 목적으로 하는 것이다.SUMMARY OF THE INVENTION Accordingly, the present invention has been made in order to solve the conventional problems, and it is an object of the present invention to provide a three-dimensional object using a photocurable resin, And to provide a UV curing apparatus capable of ensuring quality.

더불어 본 발명에서는 3D 프린터로 제작된 치과용 제작물을 복잡한 공정 없이 인체에 안전하게 사용할 수 있도록 한 살균기능을 갖춘 전문 UV 후경화장치를 목적으로 하는 것이다.Another object of the present invention is to provide a specialized UV post curing apparatus having a sterilizing function for safely using a dental preparation made of a 3D printer without any complicated process.

이를 위해 본 발명은, 수용공간을 형성하고 있는 본체가 상하방향으로 통공되고 바깥면의 차가운공기를 최대한 흡입할 수 있게 360도 전면에 통풍구를 형성하고 있는 케이스 안쪽에 장착되어 상하방향으로 유체가 이동하면서 장착된 각 광원소자를 냉각시켜 주도록 구성하는 한편, 상기 본체 안쪽에는 최적의 거리내에서 UV 광원이 조사되게 하는 파장발생부를 설치함으로써, 균일하게 조사하여 대상물을 경화시켜 고품질의 대상물을 얻는 것을 특징으로 하는 것이다.To this end, the present invention is characterized in that a main body forming a receiving space is vertically pierced and mounted on the inside of a case which forms a ventilation hole in front of 360 degrees so as to suck up cold air at the maximum, And a wavelength generating unit for irradiating a UV light source within an optimum distance is provided inside the body so as to uniformly irradiate the object and cure the object to obtain a high quality object .

In the present invention, it is possible to increase the lifetime and efficiency of the UV LED and to obtain a high-quality object by cooling and radiating the heat generated due to the characteristics of the LED element. In addition, according to the present invention, a lens body irradiates light at a wide angle, and a high-density light quantity reaches the object, so that the object is more uniformly cured within a predetermined distance to obtain high quality.

또한, 본 발명은 멀티파장을 형성함으로써, 서로 다른 액체소재로 제작된 대상물을 형성하더라도 범용성 있게 경화시켜 줄 수 있게 되었다. Further, by forming multi-wavelengths in the present invention, even if objects made of different liquid materials are formed, they can be cured with general purpose.
