Problems solved by technology

[0010] However, in the prior art, when resetting the peeling angle of the peeling part 1, because of the wrinkling of the protective film at the inflection point 2, it can only be as follows: Figure 1c In that way, the protective film is peeled off without an inflection point, so there is a limitation in the diversification of the peeling action

Abstract

The invention discloses a protective film peeling device and a protective film peeling method. The protective film peeling device of the present invention includes: a peeling part for peeling off the first protective film adhered to one side of the protective member; a peeling angle setting part for supporting the peeling part and setting a peeling angle of the peeling part; a mold force measuring part for measuring the mold release force exerted on the first protective film by the peel part; and a control part for controlling the peel angle of the peel angle setting part according to the mold release force measured by the mold release force measurement part.

Description

technical field [0001] The invention relates to a protective film stripping device and a protective film stripping method. Background technique [0002] Recently, various panels and optical films are used in the field of manufacturing display elements such as liquid crystal displays (LCD: Liquid Crystal Display), organic light emitting diodes (OLED: Organic Light Emitting Diode), and touch screens (TSP: Touch Screen Panel). [0003] This kind of panel or optical film completes the process while moving in various process spaces during the process execution process, but in order to prevent the surface of the panel or optical film from being polluted or damaged during the process of moving the process space, it is generally placed on the surface of the panel or optical film. Process with a protective film attached to the surface. [0004] This protective film needs to be removed before performing processes on the panel or optical film. [0005] In the case of adhesion between...
