Abstract

The invention provides cutting equipment for an OCA (Optical Clear Adhesive) soft adhesive tape, which is used for cutting the OCA soft adhesive tape and comprises a cooling device, a cutting device, a cutting device, a cutting device and a cutting device, and is characterized in that the cooling device is provided with a cooling inlet and a cooling outlet and is used for cooling the OCA soft adhesive tape entering the cooling device through the cooling inlet; the cutting device is used for cutting the OCA soft adhesive tape sent out from the cooling outlet; and the heating device is provided with a heating inlet and a heating outlet and is used for heating the cut OCA flexible adhesive tape entering the heating device through the heating inlet, and the heated OCA flexible adhesive tape is sent out from the heating outlet. According to the cutting equipment for the OCA flexible adhesive tape, the OCA flexible adhesive tape is cooled through the cooling device, so that the hardness of the OCA flexible adhesive tape is enhanced, the cutting device can conveniently and flexibly select a cutting tool, the defect that in the cutting process, a nicking plate is produced is overcome, the problem that the cutting cost of the OCA flexible adhesive tape is high due to the fact that dependence on the cutting tool is too large is solved, and the cutting efficiency of the OCA flexible adhesive tape is improved. And the cut OCA flexible adhesive tape is heated, so that the situation that water drops are condensed on the surface of the OCA flexible adhesive tape due to temperature difference, and subsequent winding of the OCA flexible adhesive tape is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a cutting device for OCA soft tape. Background technique [0002] OCA optical adhesive is one of the important raw materials of touch screen. It is made of optical acrylic adhesive without substrate, and then a layer of release film is laminated on the upper and lower bottom layers. It is a double-sided adhesive tape without substrate material. It has high Cleanliness, high light transmittance, low fog, high adhesion, no crystal points, no bubbles, water resistance, high temperature resistance, UV resistance and other characteristics. OCA glue is divided into soft glue and hard glue. The hard glue is easy to cut. Since the soft glue is not fully cured, it will stick to the knife when cutting, making it difficult to cut and discharge. [0003] The OCA soft tape is formed by the OCA soft adhesive attached to the bottom film. When cutting, the OCA soft adhesive on the bott...
