Polarizing film attachment device

Abstract

The invention relates to an apparatus for attaching a polarized film, and especially relates an apparatus having characteristics described as follows. In a method of attaching a polarized film onto a liquid crystal element substrate, a problems is that bubbles are generated between the polarized film and the liquid crystal element substrate because the front bending of the polarized film. A caterpillar track type adhesive plate is arranged on an inclination roller and a fixed roller on the left and the right, and a polarized film is attached to the liquid crystal element substrate after the polarized film is arranged on the amooth adhesive plate. Therefore, a phenomenon of overall bending of the polarized film does not occur. When the polarized film is attached onto the surface of the liquid crystal element substrate, the possibility of bubble generation is substantially reduced. Furthermore, the liquid crystal element is prevented from being bent due to the elongation of the polarized film, and the possibility of unqualified products is eliminated.

Description

technical field [0001] The present invention relates to a polarizing film attaching device, in particular to a device characterized in that, in the previous method of attaching a polarizing film on a liquid crystal element substrate, there was a gap between the polarizing film and the liquid crystal element substrate due to the bending of the front part of the polarizing film. To solve the problem of air bubbles between the left and right inclined rollers and fixed rollers, set a crawler-type adhesive plate on the flat adhesive plate, and then attach a polarizing film on the liquid crystal element substrate, so that no polarization occurs The phenomenon that the film is bent as a whole, when the polarizing film is attached to the surface of the liquid crystal element substrate, the possibility of bubbles is significantly reduced, and it can prevent the liquid crystal element substrate from bending due to the elongation of the polarizing film, so that there is no occurrence of d...

Problems solved by technology

[0023] And, according to the method for attaching the polarizing film in the past, the polarizing film is attached relatively lightly on the setting table 2A. At this time, the conveying roller 5 rotates. The polarizing film 2 is subjected to the force of moving in the direction of the arrow, and a tensile stress is generated on the polarizing film 2 as a whole, and the polarizing film 2 is elongated. Due to the length of the elongated polarizing film 2, the total length ratio of the elongated polarizing film 2 is The length of the liquid crystal element substrate 1 to be attached is slightly long, and as a result, there is a problem that warpage occurs on the liquid crystal element substrate 1
