Embodiment Construction

[0008] The preferred embodiments of the present invention are given below to describe the technical solution of the present invention in detail.

[0009] A method for tearing off the protective film of a polarizing plate. At a resin coating station, label printing is performed after resin coating, and the label is directly attached to the corner of the protective film where the tearing operation starts. After the assembly operator gets the screen, he presses the corner lightly with his hand, then pulls up the label, and the protective film is pulled up, removes the label and sticks it on the assembly table, and then pulls the protective film to peel it off.

[0010] When the second protective film is torn off, the assembled operator uses the label again and repeats the above action to tear off the protective film. After completing the assembly, stick the label on the designated position behind the backlight.

Abstract

The tearing deviating optical plate protective film is made by printing the label after resin coating and attaching it directly to the corner of the protective film with gentle touch at this corner, pulling off the label with the protective film at the same time, getting off the label and separating it from the protective film. It has high operatability, with reduced working speed and reduced production cost.

Description

technical field [0001] The invention relates to a method for tearing off a protective film of a polarizing plate in a liquid crystal display production process. Background technique [0002] Label printing is performed at the resin coating station, and the protective film of the polarizer is torn off at the assembly station. Before tearing off, there needs to be an adhesive tape to pull the protective film from one corner, and then peel the protective film from the screen. [0003] The existing adhesive tapes for tearing off the protective film of polarizers have poor adhesion, are not easy to tear off, have poor workability, and take a long time to assemble. It is also necessary to purchase adhesive tape, which increases the cost Contents of the invention [0004] The purpose of the present invention is to provide an easy-to-operate method for tearing off the polarizer protective film, which can shorten the working cycle. [0005] The purpose of the present invention i...
