Fine irregularities or undulations existing on the surface of the glass plate must be removed by a polishing process, and the polishing process of such a glass plate polishes individual glass plates one by one.

종래기술에 따른 휴대폰의 유리판 폴리싱 장치는, 고정테이블의 상부에 유리판을 고정한 다음 유리판의 상부에서 작동회전체에 의해 폴리싱 패드를 밀착한 상태로 회전시키면서 유리판의 상부에 분사 공급되는 연마제를 이용하여 유리판을 폴리싱하게 된다.The glass plate polishing apparatus of a mobile phone according to the prior art uses an abrasive sprayed and supplied to the top of the glass plate by fixing the glass plate on the top of the fixed table and then rotating the polishing pad in close contact with the rotating body on the top of the glass plate. Will be polished.

그러나 폴리싱 패드에 의한 유리판의 폴리싱 작업시에 폴리싱 패드가 유리판에 과도하게 밀착되거나 밀착력이 떨어지는 등 밀착력이 일정하지 않기 때문에 유리판의 투명도도 균일하지 못하였으며, 작업 중 유리판이 자주 파손되는 문제점이 있었다.However, during the polishing of the glass plate by the polishing pad, the transparency of the glass plate was not uniform because the polishing pad was excessively adhered to the glass plate or the adhesion was poor, and the adhesion was not constant.There was a problem that the glass plate was frequently damaged during operation.

이와 같이 된 본 발명에 의한 휴대폰 유리판용 폴리싱 가압장치의 실시예를 설명하면 다음과 같다.An embodiment of the polishing pressurizing device for a mobile phone glass plate according to the present invention will be described as follows.

먼저, 상기 작동회전체(30)는 좌우 이동 및 상하 이동되는 구성으로 된 작동대(40)와, 상기 작동대(40)에 수평으로 설치되는 회전축(70)과, 상기 회전축(70)에 결합되는 폴리싱 패드(80)가 결합된 구성으로 상기 폴리싱 패드(80)는 수평 회전축(70)을 따라 회전함과 아울러 좌우 이동하면서 고정테이블(20)의 안착고정부(22)에 안착시킨 유리판(A)의 폴리싱 작업이 이루어질 수 있도록 되어 있다.First, the operation rotating body 30 is coupled to the operation table 40 configured to move left and right and up and down, a rotary shaft 70 installed horizontally on the operation table 40, and the rotary shaft 70 The polishing pad 80 is a combination of the polishing pad 80, and the polishing pad 80 rotates along the horizontal axis of rotation 70 and moves left and right while the glass plate A is seated on the seating and fixing portion 22 of the fixed table 20. ) To be polished.

먼저, 작동회전체(30)의 작동대(40)에 2열로 배치된 회전축(70)의 일측 회전축(70)에는 내향 곡면용 폴리싱 패드(80)를 결합하고, 또 다른 타측 회전축(70)에는 외향 곡면용 폴리싱 패드(80)를 결합한다. First, a polishing pad 80 for an inward curved surface is coupled to one side of the rotation shaft 70 of the rotation shaft 70 arranged in two rows on the operating table 40 of the operating rotation body 30, and the other side rotation shaft 70 Combine the polishing pad 80 for an outward curved surface.

그리고, 고정테이블(20)을 폴리싱공간부(10)의 외측으로 후진시킨 다음 고정테이블(20)의 안착고정부(22)에 휴대폰에 적용되는 유리판(A)을 각각 흡착 고정하는 수단으로 유리판(A)을 안착한 다음 폴리싱 패드(80)에 의해 폴리싱이 이루어질 수 있도록 준비한다.Then, the fixed table 20 is moved backward to the outside of the polishing space 10, and then the glass plate (A) applied to the mobile phone is adsorbed and fixed to the seating and fixing portion 22 of the fixed table 20, respectively. After seating A), prepare to be polished by the polishing pad 80.

이어서, 고정테이블(20)을 폴리싱공간부(10)의 내부로 전진시켜 안착고정부(22)에 안착된 유리판(A)을 폴리싱 패드(80)의 하부에 진입시킨 다음 폴리싱이 이루어지도록 하되 작동회전체(30)의 작동대(40)를 하강시켜 유리판(A)에 폴리싱 패드(80)가 긴밀하게 접촉된 상태에서 작동대(40)를 좌우로 이동시키는 작용을 함과 아울러 연마재에 의해 폴리싱이 이루어지도록 하는 수단으로 폴리싱 패드(80)에 의해 이에 대응하는 유리판(A)의 폴리싱이 이루어지게 된다.Subsequently, the fixed table 20 is advanced into the interior of the polishing space 10, and the glass plate A seated on the seating fixing part 22 enters the lower part of the polishing pad 80, and then polishing is performed. The working table 40 of the rotating body 30 is lowered to move the working table 40 left and right while the polishing pad 80 is in close contact with the glass plate A and polished by an abrasive material. As a means to achieve this, the glass plate A corresponding thereto is polished by the polishing pad 80.

이때, 본 발명에 의한 폴리싱 패드(80)는 작동대(40)에 수평으로 설치되는 회전축(70)에 결합되어 회전축(70)을 따라 회전함과 아울러 좌우 이동하면서 고정테이블(20)의 안착고정부(22)에 안착시킨 유리판(A)에 밀착되어 폴리싱 작업이 이루어질때 폴리싱 패드(80)는 유리판(A)에 일정한 밀착력을 유지하면서 폴리싱이 이루어진다.At this time, the polishing pad 80 according to the present invention is coupled to the rotation shaft 70 installed horizontally on the operating table 40 and rotates along the rotation shaft 70 and moves left and right while the seating height of the fixed table 20 When the polishing operation is performed by being in close contact with the glass plate A seated on the top portion 22, the polishing pad 80 is polished while maintaining a constant adhesion to the glass plate A.

즉, 폴리싱 패드(80)는 중량조절부재(60)가 구비된 중량체(50)와 연결된 승강안내관(48)에 설치되어 중량체(50)의 하중이 전달되는 구성에 의해 폴리싱 패드(80)는 일정한 밀착력을 유지하게 되는것으로, 이는 유리판(A)에 밀착되어 폴리싱이 이루어지는 폴리싱 패드(80)에 과도한 가압력이 발생되어 유리판(A)이 파손되는 것을 방지함과 아울러 폴리싱 패드(80)의 가압력이 미약하여 폴리싱 효율이 저하되는 것을 방지한다.That is, the polishing pad 80 is installed on the lifting guide tube 48 connected to the weight 50 provided with the weight adjusting member 60 to transmit the load of the weight 50. ) Is to maintain a certain adhesion, which prevents the glass plate (A) from being damaged due to excessive pressing force generated in the polishing pad 80, which is in close contact with the glass plate (A) and polished. It prevents the reduction in polishing efficiency due to the weak pressing force.

그리고, 이러한 중량체(50)의 중량조절부재(60)는 작동대(40)의 연결축부(64)에 설치된 조절안내대(62)의 일측단에 중량체(50)가 연결되고 조절안내대(62)의 타측단은 중량조절 무게추(66)가 결합된 구성으로 중량조절 무게추(66)에 의해 중량체(50)의 중량조절이 이루어지는 구성이므로 폴리싱 패드(80)의 밀착력을 중량조절 무게추(66)에 의해 미리 설정한 다음 폴리싱 작업을 수행하게 된다.In addition, the weight adjustment member 60 of the weight body 50 is connected to the weight body 50 to one end of the adjustment guide 62 installed on the connection shaft 64 of the operating table 40 The other end of (62) is a configuration in which the weight adjustment weight (66) is combined, and the weight adjustment of the weight body (50) is made by the weight adjustment weight (66), so the adhesion of the polishing pad (80) is weight controlled. After setting in advance by the weight 66, the polishing operation is performed.

상기와 같은 과정으로 유리판(A)의 폴리싱 공정이 완료되면, 작동회전체(30)의 작동대(40)를 상승시켜 폴리싱 패드(80)를 유리판(A)과 이격시킨 다음 고정테이블(20)을 후진시켜 폴리싱공간부(10)의 외부로 위치시킨 다음 고정테이블(20)의 안착고정부(22)는 흡착력을 해제하여 폴리싱이 완료된 유리판(A)을 배출한 다음 또 다른 폴리싱을 하기 위한 유리판(A)을 안착고정부(22)에 안착시킨다.When the polishing process of the glass plate (A) is completed in the same process as described above, the operating table 40 of the operating rotating body 30 is raised to separate the polishing pad 80 from the glass plate A, and then the fixed table 20 After reversing the polishing space part 10, the seating fixing part 22 of the fixing table 20 releases the adsorption force to discharge the polished glass plate A, and then a glass plate for another polishing. (A) is settled on the seating and fixing part 22.

이와 같이 본 발명에 의한 휴대폰 유리판용 폴리싱 가압장치는 휴대폰의 본체 전면에 설치되는 유리판(A)을 전,후진되는 고정테이블(20)에 2열로 배치된 안착고정부(22)의 상면에 각각 안착시킨 다음 폴리싱 패드(80)가 작동대(40)의 수평 회전축(70)에 각각 결합되어 승강 및 좌우 이동시키는 작동으로 폴리싱이 이루어지되 폴리싱 패드(80)가 유리판(A)에 밀착력을 갖도록 하는 중량체(50)의 하중은 중량조절 무게추(66)에 의해 간편하게 조절할 수 있게 되므로 폴리싱 패드(80)는 장기간 사용시에도 항상 일정한 압력으로 유리판(A)을 균일하게 폴리싱을 할 수 있게 됨과 아울러 작업 생산성을 크게 높일 수 있는 것이다.As described above, the polishing pressurization device for a glass plate for a mobile phone according to the present invention is a glass plate (A) installed on the front of the main body of the mobile phone and is mounted on the upper surface of the mounting fixing portions 22 arranged in two rows on the fixed table 20 that is forward and backward. Next, the polishing pad 80 is coupled to the horizontal rotation shaft 70 of the operating table 40, and the polishing is performed by lifting and moving left and right, but the polishing pad 80 is a heavy body to have adhesion to the glass plate (A). Since the load of 50 can be easily adjusted by the weight adjustment weight 66, the polishing pad 80 can always polish the glass plate A uniformly with a constant pressure even when used for a long period of time, and increase work productivity. It can be greatly enhanced.
