OCA (optically clear adhesive) optical membrane separation device

Abstract

The invention belongs to the technical field o touch screen production and in particular discloses an OCA (optically clear adhesive) optical membrane separation device which comprises a separation machine, wherein the separation machine comprises a pair of a fixing bottom plate and a lifting plate parallel to each other; side edges of the fixing bottom plate and the lifting plate are moveably connected through two telescopic cylinders and two guide columns; ten lower gas guide tubes are vertically mounted on the top surface of the fixing bottom plate; ten upper gas guide tubes are vertically mounted on the bottom surface of the lifting plate; both the ten lower gas guide tubes and the ten upper gas guide tubes are oppositely arranged; and opposite ends of the lower gas guide tubes and theupper gas guide tube are sleeved by silica gel suckers. As protection layers on both sides of an OCA optical membrane are respectively sucked by the silica gel suckers connected with the lower gas guide tubes and the upper gas guide tubes, hands or other articles are prevented from touching the adhesion surface of the OCA optical membrane, the surface of the OCA optical membrane can be clean, theadhesion quality is high, and the adhesiveness can be ensured.

Description

technical field [0001] The invention belongs to the technical field of touch screen production, and in particular relates to an OCA optical film separation device. Background technique [0002] OCA optical film is made of optical acrylic adhesive without substrate, and then a layer of release film is attached to the upper and lower bottom layers as a protective layer. It is a double-sided adhesive tape without substrate material, which has excellent clarity. Degree, high light transmittance and other advantages. [0003] Before the OCA optical film is used, both sides are attached with a protective layer. When using it, the protective layer on both sides needs to be torn off and separated manually. However, the existing OCA optical film separation device has the following problems: [0004] 1. You need to use fingernails or blades to pick apart the protective surfaces on both sides before it can be used, which is inefficient; [0005] 2. It is easy to be contaminated with ...
