Stripping device of polarizer sheet

Abstract

The invention discloses a removing device of a polaroid, which comprises a vacuum cup, a locating board and a control mechanism. The vacuum cup is used for bearing a substrate stuck with the polaroid. The vacuum cup includes a plurality of adsorption holes and at least one evacuation hole; the adsorption holes are used for sucking the lower surface of the substrate; the evacuation hole is communicated with the adsorption holes. The locating board is arranged on the vacuum cup and includes a first locating side and a second locating side; the two neighboring side walls of the substrate respectively lean against the first locating side and the second locating side. The control mechanism is connected to the evacuation hole of the vacuum cup and is used for controlling the vacuum opening or vacuum closing of the vacuum cup. When the polaroid is removed, a balancing force applied on the lower surface of the substrate can balance removing force applied on the upper surface of the substrate, thereby being capable of removing the deformation of the substrate and preventing the substrate from cracking.

Description

【Technical field】 [0001] The invention relates to a peeling device for a polarizer, in particular to a peeling device which can safely peel off a polarizer from a substrate. 【Background technique】 [0002] Polarizer is an optical film composed of multi-layer polymer materials with the function of generating polarized light. It is used in Liquid Crystal Display (LCD) and can convert non-polarized natural light into polarized light. , so that the light perpendicular to the electric field passes through, so that the liquid crystal display panel (LCD panel) can display images normally. It can be seen from this that the polarizer is one of the key elements that affect the display effect of the liquid crystal display panel. [0003] The polarizer is attached to the liquid crystal display panel by an adhesive (such as pressure-sensitive adhesive), so a certain peeling force (or adhesive force) is generated between the polarizer and the liquid crystal display panel. Although the i...

However, during the peeling process, the peeling force F between the two will lift the liquid crystal display panel 82, causing the liquid crystal display panel 82 to be bent and deformed, such as Figure 1B A schematic diagram of the bending deformation of the liquid crystal display panel 82 caused by the traditional stripping method shown

When the deformation of the liquid crystal display panel 82 exceeds its limit value, the liquid crystal display panel 82 will be cracked and damaged.

[0004] As the thickness of liquid crystal displays becomes thinner and thinner, the thickness of liquid crystal display panels will become thinner and thinner, and the traditional method of peeling off polarizers will become more and more difficult
