Description

Protective sheet separating device of polarizing film {apparatus for separate cover-sheet from polarizing film}

The present invention relates to a protective sheet separating apparatus of a polarizing film, and more particularly, to a protective sheet separating apparatus of a polarizing film that can easily separate and remove the protective sheet stuck to the polarizing film.

The substrate module for a flat panel display device is composed of two integrated substrates, and a polarizing layer is formed on an outer surface of each substrate.

The polarizing layer is intended to allow only the wavelength and light oscillating in a specific direction to pass through the liquid crystal, and is mainly formed by attaching a polarizing film to the substrate side.

As such, a device for use in forming a polarizing layer is disclosed as a polarizing film applying device of Patent No. 10-0768470, which is a protective film (hereinafter referred to as "protection" that adheres to one surface of the polarizing film before the polarizing film is attached. And a remover for separating and removing the sheet.

That is, the remover can be separated and removed by pulling the protective sheet back by the adhesive force of the tape while horizontally conveying the tape (forward / backward) toward the polarizing film in the workbench.

However, the eliminator occupies an excessive area and space in the working surface by the horizontal conveying section of the tape, making it difficult to realize the miniaturization of the device.

In particular, according to this separation structure, the larger the size of the polarizing film (protective sheet), the longer the length of the horizontal transfer section of the tape has a problem that the size of the device becomes larger.

In addition, the method of pulling back the protective sheet at a time by the horizontal transfer operation of the tape may cause the protective sheet to easily fall off the adhesive surface of the tape during the separating operation.

This phenomenon is because a relatively large resistance occurs when the protective sheet is pulled at a time by horizontal movement.

In addition, since the remover does not have a means for collecting the protective sheet, such a structure requires the tape to be wound around the recovery reel side by the length of the protective sheet after the separation operation, so that the tape is excessively consumed. have.

Furthermore, the manner of collecting the protective sheet on the recovery reel side may be one factor that causes various malfunctions, for example, when the protective sheet falls to the work surface and gets caught in the device gap of the transport and drive system.

The present invention has been made to solve the conventional problems as described above,
