Release film collection device for ultra-thin glass and ultra-thin glass laminated sheet {RELEASE FILM COLLECTING DEVICE OF LAMINATING SHEET}

The present invention relates to a release film collecting device for ultra-thin glass clad sheets, and more particularly, a protective film attached to the upper and lower surfaces of the ultra-thin glass of the laminated block is transported through the filler device by holding the release film (grip). ), separates the caught release film from the filler device, and collects the separated release film by putting it in a waste bin (trash).

In recent years, electrical and electronic technologies have rapidly developed, and various types of display products have been released to meet the needs of a new era and the needs of various consumers. Among them, research on flexible displays that can be folded and unfolded is active. Accordingly, there is an increasing demand for flexible glass articles for use in various applications requiring flexible and bendable glass (glass). For example, flexible display devices for mobile phones, tablets, and other portable electronic devices include flexible glass that must be bent or folded without breaking. However, traditionally glass has been considered to be rigid in nature, and therefore alternative materials for use in place of glass have been considered.

As an alternative to glass (glass), polymer films made of polymer have been considered and studied for use in flexible display devices. In the case of such a polymer film, the mechanical strength is weak, so it merely serves to prevent scratches on the display panel, but it is weak in impact resistance, has low transmittance, and is known to be relatively expensive.

On the other hand, it is known that if the glass is made of ultra-thin glass of 0.1 mm (100 μm) or less in order to be applied to a flexible display product, this is satisfied.

Ultra-thin glass is manufactured using dip, spray, or dip & spray methods and is manufactured through processing methods such as grinding, but there is a high risk of breakage or breakage due to cracks in the process of making thin.

In addition, the manufactured ultra-thin glass is polished or rounded on the cut side by a cutting and polishing process, and the treated ultra-thin glass is cohesively packaged with a protective film, etc. and delivered to a subsequent process. At this time, various protective films have been developed to protect the upper and lower surfaces of the ultra-thin glass by bonding them together with a protective film. As one of such technologies, a display screen protection film and a display packaging bag using the film are disclosed in Korean Patent Publication No. 10-1249673.

The technique consists of three layers of an outer layer, a middle layer and an inner layer, wherein the outer layer consists of an outer layer forming composition containing 100 parts by weight of polyethylene and 10 to 40 parts by weight of a pigment, and the middle layer is 100 parts by weight of polyethylene and 10 to 40 parts by weight of a pigment It consists of a composition for forming an intermediate layer containing parts by weight, and the inner layer is characterized in that it consists of an inner layer composition containing 100 parts by weight of polyethylene and 0.5 to 5 parts by weight of carbon nanotubes.

However, in the automatic bonding system that protects the ultra-thin glass by attaching the film to the ultra-thin glass, the release film of the bonding sheet is peeled off and a protective film is attached to each of the upper and lower surfaces of the ultra-thin glass. In the process, the bonding sheet The filler device from which the release film has been peeled off does not fall off by free fall. Therefore, there is a need for a release film collecting device capable of holding the release film in the filler device, separating the filler device and the release film, and collecting the separated release film.
