In the drawings, 1 is a glass substrate for applying a spacer, 2 is a case into which the glass substrate 1 is placed, 3 is a spray cover for spraying the spacer onto the glass substrate, 4 is a nozzle into which the spacer is introduced, and 4 'is a gas.

Represent each.
스페이서를 유리기판에 도포하는 과정은 다음과 같다.The process of applying the spacer to the glass substrate is as follows.
프레온등의 액체에 적당량의 스페이서를 혼합하여 용기(6)에 넣은후 모터(7)를 회전시키면, 모터에 연결된 날개(9)의 회전에 의하여 스페이서가 엑체와 혼합된다. 스페이서가 혼합된 액체(5)는 노즐(4)을 통하여 분사버퍼(3)에 공급되고 또한 분사버퍼(3)에는 솔레노이드밸브(13)에 의하여 발생된 고압의 기체가 노즐(4')을 통하여 공급된다. 이때 분사버퍼에서는 상기 공급된 고압기체에 의하여 분사구가 개방되어 스페이서가 혼합된 액체가 유리기판(1)에 분사된다. 유리기판(1)에 분사되는 액체의 도포면적은 분사버퍼(3)의 높이를 조정밸브(12)에 의하여 조정함으로서 조절한다. 스페이서가 혼합된 액체를 유리기판에 분사하면서 가열로(14)에 의하여 유리기판을 가열하면 유리기판에는 액체가 기화되어 증발되고 스페이서만이 잔류하게 된다.When a suitable amount of spacer is mixed with a liquid such as Freon and put into the container 6 and the motor 7 is rotated, the spacer is mixed with the liquid by the rotation of the blade 9 connected to the motor. The liquid mixed with the spacer 5 is supplied to the injection buffer 3 through the nozzle 4, and the high pressure gas generated by the solenoid valve 13 is supplied to the injection buffer 3 through the nozzle 4 ′. Supplied. At this time, in the injection buffer, the injection port is opened by the supplied high pressure gas, and the liquid mixed with the spacer is injected onto the glass substrate 1. The application area of the liquid sprayed on the glass substrate 1 is adjusted by adjusting the height of the injection buffer 3 by the adjustment valve 12. When the glass substrate is heated by the heating furnace 14 while spraying the liquid mixed with the spacer, the liquid vaporizes and evaporates on the glass substrate, and only the spacer remains.
그러나 이와 같이 구성된 종래의 스페이서 분사장치에 있어서는 스페이서를 포함한 액체가 분사버퍼에 도달하였을때 스페이서와 이를 포함하는 액체간에는 중량의 차가 존재하기 때문에 스페이서가 침전되어 엉기는 현상이 발생하며 따라서 유리기판에 스페이서를 균일하게 도포시키는데 많은 어려움이 있었다.However, in the conventional spacer injector configured as described above, when the liquid including the spacer reaches the injection buffer, there is a difference in weight between the spacer and the liquid including the same. There were many difficulties in uniformly applying.
따라서 본 고안에서는 스페이서의 침전을 방지하여 유리기판에 스페이서가 균일하게 도포될 수 있도록 한스페이서 분사장치를 제공하고자 한 것이다. 이를 위하여 본 고안에서는 종래 장치의 분사버퍼를 그 구성을 달리하여 제조하였다.Therefore, the present invention is to provide a spacer injection device so that the spacer can be uniformly applied to the glass substrate by preventing the precipitation of the spacer. To this end, in the present invention, the injection buffer of the conventional apparatus was manufactured with different configurations.
제2도는 본 고안에 따라 구성된 분사버퍼의 내부구성을 도시하기 위해 단면도로서 표시한 것이고, 제3도는 제2도에서 사용되는 압전소자를 평면도로 도시한 것이다.Figure 2 is shown as a cross-sectional view to show the internal configuration of the injection buffer constructed in accordance with the present invention, Figure 3 shows a piezoelectric element used in Figure 2 in a plan view.
제2도에 있어서, 제1도와 동일 부호는 동일부품을 나타내며, 3-1은 분사버퍼의 외부 케이스, 3-2는 분사구, 3-3은 압전소자, 3-4는 전극을 나타낸다. 본 고안의 분사버퍼의 구성은 분사구(3-2)의 바로위에 진동판과 초음파 진동자로 이루어진 압전소자(3-3)를 설치하고 압전소자에 전극(3-4)을 형성하여 외부에서 전원을 인가할 수 있도록 되어 있다. 상기 압전소자(3-3)는 제3도에 평면도로 도시되어 있다.In FIG. 2, the same reference numerals as in FIG. 1 denote the same parts, 3-1 denotes an outer case of the injection buffer, 3-2 denotes an injection port, 3-3 denotes a piezoelectric element, and 3-4 denotes an electrode. The configuration of the injection buffer of the present invention is to install a piezoelectric element (3-3) consisting of a diaphragm and an ultrasonic vibrator directly above the injection hole (3-2) and to form the electrode (3-4) in the piezoelectric element to apply power from the outside I can do it. The piezoelectric element 3-3 is shown in plan view in FIG.
제1도의 액체를 수용하는 용기로 부터 노즐(4)을 통하여 분사버퍼에 스페이서를 포함한 액체가 들어왔을때 분사버퍼(3)의 압전소자(3-3)에 전원을 인가하면 압전소자가 음파 또는 초음파영역의 주파수를 갖는 운동을 행하게되며, 이로서 스페이서가 분사버퍼내에서 침전되어 응고하는 것을 방지할 수 있다. 이 상태에서 노즐(4')을 통하여 고압의 기체를 분사버퍼내에 주입하면 분사버퍼는 그 기체압력에 의하여 스페이서를 포함한 액체를 분사구(3-2)를 통하여 유리기판(1)상에 균일하게 도포한다. 이때 스페이서외의 액체는 가열로에서 발생한 열에 의하여 유리기관에서 증발하여 없어지고 유리기판(1)상에는 스페이서만이 남게된다.When the liquid containing the spacer enters the injection buffer through the nozzle 4 from the container containing the liquid of FIG. 1, when the power is applied to the piezoelectric element 3-3 of the injection buffer 3, the piezoelectric element is sound wave or ultrasonic wave. The movement with the frequency of the region is performed, thereby preventing the spacer from settling and solidifying in the injection buffer. In this state, when high-pressure gas is injected into the injection buffer through the nozzle 4 ', the injection buffer uniformly applies the liquid including the spacer onto the glass substrate 1 through the injection hole 3-2 according to the gas pressure. do. At this time, the liquid other than the spacer is evaporated and disappeared from the glass engine by the heat generated in the heating furnace, and only the spacer remains on the glass substrate 1.
이상 설명한 바와 같이 스페이서 분사장치의 분사버퍼를 본 고안에 따라 구성하면 분사버퍼내에서 스페이서가 침전되어 응고하는 것을 방지할 수 있으므로 유리기판상에 스페이서를 균일하게 도포할 수 있게 된다.As described above, if the injection buffer of the spacer injector is configured according to the present invention, the spacer can be prevented from being precipitated and solidified in the injection buffer, so that the spacer can be uniformly coated on the glass substrate.
