휴대폰 표시창 어셈블리의 제조방법{Method for manufacturing a display window assembly for a mobile phone}Method for manufacturing a display window assembly for a mobile phone}

본 발명은 휴대폰 표시창에 관한 것으로서, 더욱 상세하게는 제조공정 중 오염이 발생하는 것을 방지하는 휴대폰 표시창 어셈블리의 제조방법에 관한 것이다.The present invention relates to a mobile phone display window, and more particularly, to a method for manufacturing a mobile phone display assembly to prevent the occurrence of contamination during the manufacturing process.

휴대폰 표시창의 개발 초기에 상기 표시창은 투명한 합성수지(PMMA: Polymethylmethacrylate)의 재질로 제조되었다. 그러나 휴대폰 표시창의 재질이 합성수지인 경우, 제조과정 중 사출성형 시 수축 등에 의해 형태가 변형되거나, 휴대폰의 사용 중 발생하는 열에 의해 형태가 변형될 우려가 있어 일정 두께 이상으로 설계, 제조되어야 하는 한계가 있었다. 또한, 합성수지의 재질로 인해 휴대폰의 사용 중 표시창이 긁히거나, 충격으로 인해 표시창이 파손될 우려가 있었다.In the early stage of the development of a mobile phone display window, the display window was made of a transparent synthetic resin (PMMA: Polymethylmethacrylate). However, when the material of the display window of the mobile phone is made of synthetic resin, the shape may be deformed due to shrinkage during injection molding or the heat generated during the use of the mobile phone. there was. In addition, due to the material of the synthetic resin, the display window may be scratched during use of the mobile phone, or the display window may be damaged due to the impact.

합성수지 재질의 휴대폰 표시창이 가지는 상기 문제점을 보완하기 위해 내구성 및 내열성이 우수한 강화유리를 휴대폰 표시창의 재질로 사용하고, 큰 충격으로 인해 발생할 수 있는 휴대폰 표시창의 비산을 방지하기 위해 상기 강화유리의 내측면에 수지필름을 적층함으로써 휴대폰 표시창의 어셈블리를 제조하는 방법이 개발되었다.In order to compensate for the above problems of the mobile phone display window made of synthetic resin material, a tempered glass having excellent durability and heat resistance is used as the material of the mobile phone display window, and the inner surface of the tempered glass to prevent scattering of the mobile phone display window that may be caused by a large impact. A method of manufacturing an assembly of a mobile phone display window has been developed by laminating a resin film on the substrate.

강화유리 재질의 휴대폰 표시창 어셈블리에 대한 종래의 제조방법은 먼저, 강화유리 및 수지필름을 휴대폰 표시창의 어셈블리에 대응되는 크기로 절단하는 단계로부터 시작된다.A conventional manufacturing method for a mobile phone display window assembly made of tempered glass is first started by cutting the tempered glass and the resin film to a size corresponding to the assembly of the mobile phone display window.

다음으로, 상기 강화유리의 접착면에 점착액을 도포함으로써 점착층을 형성한다. 상기 점착층의 형성은 상기 강화유리에 상기 수지필름을 부착하기 위함이다.Next, an adhesive layer is formed by apply | coating an adhesive liquid to the adhesive surface of the said tempered glass. The adhesive layer is formed to attach the resin film to the tempered glass.

이어서, 상기 점착층이 형성된 상기 강화유리의 접착면에 상기 수지필름을 안착한다. 상기 강화유리의 접착면에 상기 수지필름을 안착하는 것은 강한 충격에 의해 상기 강화유리가 파손되는 경우에 발생할 수 있는 조각 또는 파편의 비산을 방지하기 위함이다.Subsequently, the resin film is seated on an adhesive surface of the tempered glass in which the adhesive layer is formed. Seating the resin film on the adhesive surface of the tempered glass is to prevent scattering of pieces or debris that may occur when the tempered glass is broken by a strong impact.

다음으로, 상기 수지필름이 안착된 강화유리에 압력을 가하고 상기 점착액을 경화시켜 상기 수지필름을 상기 강화유리에 부착한다. 이때, 상기 수지필름이 안착된 상기 강화유리에 압력을 가함으로써 상기 점착층을 형성한 상기 점착액이 상기 수지필름 및 강화유리의 외측면으로 흘러 상기 수지필름 및 강화유리를 오염시키게 된다.Next, pressure is applied to the tempered glass on which the resin film is seated, and the adhesive solution is cured to attach the resin film to the tempered glass. At this time, by applying pressure to the tempered glass on which the resin film is seated, the pressure-sensitive adhesive formed the pressure-sensitive adhesive layer flows to the outer surfaces of the resin film and the tempered glass to contaminate the resin film and the tempered glass.

이어서, 상기 수지필름 및 강화유리의 외측면에 형성된 오염물을 제거하기 위해 1차 세척을 수행한다.Subsequently, a first wash is performed to remove contaminants formed on the outer surfaces of the resin film and the tempered glass.

다음으로, 휴대폰 표시창 어셈블리에 대해 외관 검사를 수행한다. 외관 검사 단계에서는 상기 수지필름 및 강화유리의 접착부에 대해 기포의 유무를 확인하고, 상기 압착과정에서 외부로 흘러나온 점착액에 의한 오염물의 잔존 여부를 검사한다.Next, a visual inspection is performed on the mobile phone display assembly. In the external inspection step, the presence or absence of bubbles in the adhesive parts of the resin film and the tempered glass is checked, and the presence of contaminants due to the adhesive solution flowing out to the outside during the pressing process is examined.

이어서, 상기 수지필름 및 강화유리 사이에 기포가 발생한 경우, 기포를 제거한다. 그리고 상기 수지필름 및 강화유리의 외측면에 잔존하는 오염물을 제거하기 위해 2차 세척을 수행한다.Subsequently, when bubbles are generated between the resin film and the tempered glass, bubbles are removed. Then, the second washing is performed to remove contaminants remaining on the outer surfaces of the resin film and the tempered glass.

그러나 상기한 바와 같은 종래기술에서는 다음과 같은 문제점이 있었다. However, the prior art as described above has the following problems.

즉, 수지필름이 안착된 강화유리에 압력을 가하는 단계에서 점착액이 외부로 흘러나와 수지필름 및 강화유리의 표면을 오염시켜 제품의 불량률이 높은 문제점이 있었다.That is, in the step of applying pressure to the tempered glass on which the resin film is seated, the adhesive liquid flows outward to contaminate the surface of the resin film and the tempered glass, thereby causing a high defect rate of the product.

그리고 종래기술에서는 수지필름 및 강화유리의 표면에 발생한 오염을 제거하기 위해 1차 및 2차 세척작업을 수행하여야 하므로 작업공수의 효율이 떨어지는 문제점이 있었다.In the prior art, the first and second cleaning operations have to be performed to remove the contamination on the surface of the resin film and the tempered glass.

또한, 상기 수지필름 및 강화유리의 표면에 발생한 오염을 제거하는 단계는 제품의 외관을 작업자가 일일이 검사하고, 1차 및 2차에 걸친 세척단계가 수작업으로 이루어져야 하는 문제점이 있었다.In addition, the step of removing the contamination generated on the surface of the resin film and the tempered glass has a problem that the operator inspects the appearance of the product one by one, and the washing step for the first and second steps must be performed manually.

따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로, 본 발명의 목적은 점착액이 외부로 흘러나와 수지필름 및 강화유리의 표면에 오염물이 발생하는 것을 방지할 수 있는 휴대폰 표시창 어셈블리의 제조방법을 제공하는 것이다.Therefore, the present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is a mobile phone display assembly that can prevent the contamination of the adhesive film flows to the outside and the surface of the resin film and tempered glass It is to provide a manufacturing method.

본 발명의 다른 목적은, PET필름 및 강화유리의 표면에 발생한 오염물을 제거하기 위한 1차 및 2차 세척작업을 생략하여 작업공수를 줄일 수 있는 휴대폰 표시창 어셈블리의 제조방법을 제공하는 것이다.Another object of the present invention is to provide a method for manufacturing a mobile phone display assembly that can reduce the number of work by eliminating the first and second cleaning operations for removing contaminants generated on the surface of PET film and tempered glass.

상기한 바와 같은 목적을 달성하기 위한 본 발명의 특징에 따르면, 본 발명은 강화유리 및 비산방지필름의 비접착면에 오염방지필름을 부착하는 단계와, 상기 강화유리와 비산방지필름의 접착면이 서로 맞닿도록 하여 접착하는 단계, 그리고 상기 오염방지필름을 제거하는 단계를 포함한다.According to a feature of the present invention for achieving the object as described above, the present invention comprises the step of attaching the antifouling film to the non-adhesive surface of the tempered glass and shatterproof film, Adhesion to the contact with each other, and removing the anti-fouling film.

이때, 상기 오염방지필름은 상기 강화유리 및 비산방지필름 이상의 면적으로 형성될 수 있다.At this time, the anti-fouling film may be formed in the area of the tempered glass and scattering prevention film or more.
