Glass aligning and laminating device for capacitive touch screen production

Abstract

The invention discloses a glass aligning and laminating device for capacitive touch screen production in the technical field of touch screen production, and the glass aligning and laminating device comprises a bottom plate, a belt conveying device is arranged on the bottom plate, and mounting plates are fixedly connected to the front side and the rear side of the top of the bottom plate; the two mounting plates are jointly connected with a fixing plate located above the belt conveying device in a sliding mode, and a plurality of air blowing pipes are fixedly connected to the fixing plate. The two mounting plates are jointly slidably connected with a first sliding plate in the left-right direction, the first sliding plate is rectangular, oblique sliding grooves are formed in the four corners of the bottom of the first sliding plate in the diagonal direction, and clamping plates are slidably connected into the oblique sliding grooves; the top of the clamping plate is rotationally connected with an air spring, and the air spring is rotationally connected with the top of the first sliding plate. The four clamping plates are jointly and fixedly connected with screen wiping cloth, and a wiping plate is arranged above the screen wiping cloth; according to the invention, the working efficiency can be higher when the touch screen is laminated.

Description

technical field [0001] The invention relates to the technical field of touch screen production, in particular to a glass alignment and bonding device for capacitive touch screen production. Background technique [0002] Capacitive touch screen technology uses the current induction of the human body to work. 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 ITO is the shielding layer to ensure a good working environment. When a finger touches the metal layer, due to the electric field of the human body, a coupling capacitance is formed between the user and the surface of the touch screen. For high-frequency currents, the capacitance is a direct conductor, so the finger absorbs a small current from the contact point....

AI Technical Summary

Problems solved by technology

[0003] Since the capacitive touch screen uses the current induction of the human body to work, if the surface of the touch screen is contaminated with dust, the touch screen will not be able to receive the current of the human body sensitively. During the production process of the capacitive touch screen, the dust on the surface of the composite glass needs to be wiped clean. The technology is usually that the staff manually wipe the composite glass, which is inefficient and not suitable for mass production, and if there is a mistake, it will easily cause dust to be wiped clean, which will lead to unqualified quality of the touch screen
