Capacitive touch screen production process

Abstract

The invention relates to the technical field of capacitive touch screen production, in particular to a capacitive touch screen production process which comprises the steps that an operator takes a capacitive screen cover plate for appearance inspection, and the surface of a capacitive screen is wiped for dust removal; the capacitive screen cover plate in the first step is overturned and placed on double-faced adhesive tape film removing equipment, the inner side of the capacitive screen cover plate faces upwards, and after the side edge of the capacitive screen cover plate is aligned with the double-faced adhesive tape film removing equipment, four double-faced adhesive tape isolating films on the edge of the capacitive screen cover plate are torn off. According to the device, the handle is pressed to enable the rolling wheel to make contact with the top face of the guide rail, the rubber plate is bonded with the end of the double-faced adhesive tape isolating membrane, one end of the isolating membrane is dragged to be evenly wound around the outer side wall of the large end of the outer side conical shell, and therefore the double-faced adhesive tape isolating membrane can be conveniently removed; the probability of deformation of the end part of the double-sided adhesive tape caused by manual tearing by an operator can be reduced, so that the probability of a gap at the connecting part of the capacitive screen cover plate and the capacitive screen base is reduced, and the efficiency of removing the isolating membrane of the double-sided adhesive tape of the capacitive screen cover plate is improved.

[0002] The capacitive touch screen is a four-layer composite glass screen. The inner surface and interlayer of the glass screen are each coated with a layer of ITO. The outermost layer is a thin layer of silica glass protective layer. The interlayer ITO coating is used as the working surface. Four electrodes, the inner layer of ITO is the shielding layer to ensure a good working environment. During the production of capacitive touch screens, it is necessary to cover the capacitive screen cover with double-sided adhesive on the capacitive screen base for assembly. However, in actual production During the process, the operator is often required to manually assemble the cover and the base, and during the assembly process, it is necessary to manually tear off the double-sided adhesive isolation film on the inner edge of the capacitive screen cover, and then attach it to the capacitive screen base. For bonding, because the isolation film needs to be pressed when tearing it off manually, it is easy to cause the end of the double-sided adhesive to sag, so that when the capacitive screen cover is connected to the base, it is easy to cause the depression to not be sealed tightly, and when the isolation film is removed It is not convenient to handle the removed isolation film during the process, which affects the efficiency of capacitive screen production
