Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below with reference to the drawings.

[0026] 1 and 2 show a plan view and a cross-sectional view of an apparatus for removing a polarizer protective film according to an embodiment of the present invention.

[0027] This removal device includes a pair of guide rails 100 , a stage unit 110 , a transfer unit 200 , a protective film peeling unit 300 , and a removal unit 400 .

[0028] The pair of guide rails 100 extend in a predetermined direction (hereinafter referred to as the X-axis direction) parallel to each other. The stage unit 110 is a planar support stand provided between the pair of guide rails 100 . The polarizing plate 1 is supported on the stage portion 110 in a state where the longitudinal direction is aligned with the X-axis direction and the protective film 2 faces outward. The stage part 110 is preferably formed with a plurality of suction ports 110a. The polarizing plate 1 is adsorbed a...

Abstract

The invention provides an apparatus for removing a polaroid sheet protection film, reducing the production cost of a display apparatus by removing the protection film from the polaroid sheet without consuming splicing tape, and realizing the improvement of utilization rate and productbility. The removing apparatus of the invention enables the body of the protection film peeling part to move along a guide rail by adopting a transferring part. A peeling roller can rotate surrounding a centre axis to splice the protection film at the periphery. The connecting part can rotate surrounding the rotating axis fixed at the body to connect the rotating axis and the centre axis of the peeling roller. The periphery of the peeling roller is temporarily contacted with the surface of the protection film by the rotation of the connecting part surrounding the rotating axis, then enabling the peeling roller moving away from the polaroid sheet. One end of a clamp part is connected with a rotating axis of the connecting part and the other end is near to the outer periphery of the peeling roller. When the connecting part rotates and the peeling roller is moving away from the polaroid sheet, it is contacted with the back of the protection film spliced at the outer periphery of the peeling roller.

Description

technical field [0001] The present invention relates to a manufacturing process of a liquid crystal display device, in particular to a process of removing a protective film from a polarizing plate. Background technique [0002] A liquid crystal display device is one of the most widely used flat panel display devices today. A liquid crystal display device consists of two display panels and a liquid crystal layer sandwiched between them. An electrode for generating an electric field corresponding to each pixel is generally formed on the display panel. When a voltage is applied to an electrode generating an electric field, the liquid crystal layer portion included in each pixel generates an electric field having a strength corresponding to the voltage level, and the alignment direction of liquid crystal molecules changes according to the electric field strength. When light passes through this portion of the liquid crystal layer, its polarization direction is rotated by an ang...
