Description

  The present invention relates to a polarizing film carrier, and more particularly to a carrier that can be gripped and transported while maintaining flatness at each working position when inspecting a polarizing film applied to LCD.

  There are various types of polarizing films applied to LCD (Liquid Crystal Display) such as iodine-based, dye-based, phase difference, transflective and reflective types. Among them, iodine-based polarizing films are highly transmissive and highly polarized. It is a polarizing film for high-definition LCDs that has characteristics, and it can absorb light in the visible light region by applying iodine to a transparent PVA (Poly Vinyl Alcohol) film.

  The schematic structure of the polarizing film is configured by sequentially laminating a TAC (Tri-Acetyl-Cellulose) film, an adhesive, a polarizing element, an adhesive and a TAC film. In order to manufacture a polarizing film having such a configuration, a roller or the like is used, and while the polarizing film is manufactured by the roller, fine scratches can be generated in the polarizing film due to the frictional force of the roller. In the PVA film layer, kuniku may occur due to fine deformation or damage. When defects such as nicks or scratches occur in the polarizing film as described above, when the LCD screen is driven, a fatal defect that causes unevenness on the screen may occur.

  A polarizing film inspection apparatus is applied to inspect whether there is a defect in a polarizing film that can cause a fatal defect on the LCD screen. A polarizing film inspection apparatus separates and inspects an inspection work position for inspecting foreign matters or bubbles that are included in the polarizing film and causing defects, and an inspection work position for inspecting nick defects. When a polarizing film applied to a small screen LCD such as a 17 inch or 19 inch is transferred to each inspection work position of such a polarizing film inspection apparatus, the flatness of the polarizing film is maintained at each inspection work position. A carrier that can be transported in the state is required.

Therefore, the present invention is for solving the above-described problems, and when inspecting for the presence or absence of a polarizing film using a polarizing film inspection apparatus, the flatness of the polarizing film is maintained at each inspection work position. It is providing the polarizing film carrier which can be conveyed in a state.
Another object of the present invention is that the polarizing film can be safely transferred to each inspection work position of the polarizing film inspection apparatus while maintaining the flatness, and the function of the inspection stage of the polarizing film can be achieved at each inspection work position. It is in providing the polarizing film carrier which can do.

When the polarizing film (7) is gripped by meshing with each other (17, 27), the first and second upper grip members (16, 26) have a predetermined distance from the first and second lower grip members (17, 27). The polarizing film (7) can be gripped in a state of being further projected by (n1), and the predetermined distance (n1) by which the first and second upper grip members (16, 26) are projected is 0 to 0. Within 5 mm.

  When the first and second upper grip members (16, 26) and the first and second lower grip members (17, 27) hold the polarizing film (7), the holding interval (n2) is set to the polarizing film (7 ) From 2.0 to 2.5 mm from the edge of the film to minimize the loss of the polarizing film (7) and to prevent the polarizing film (7) from bending. Grab. Further, in order to minimize the loss due to the gripping of the first gripper (10) and the second gripper (20), the first and second upper grip members (16, 26) and the first and second lower grip members (17) are used. 27) is applied to the surface with either a matte white rubber material or a matte white plastic material to increase the frictional force so that it can be stably gripped.

  Thus, when inspecting the presence or absence of defects in the polarizing film using the polarizing film inspection device, the polarizing film carrier is held in a state where the flatness of the polarizing film is maintained, and then safely and quickly transferred to each inspection work position. The productivity of the polarizing film inspection work can be improved by performing the function of the polarizing film inspection stage at each inspection work position.
