Abstract

According to the invention, the opening, punching and profiling of a touch screen substrate are formed in one step through a carving machine, the rough grinding and polishing comprise ultrasonic cleaning equipment, and the ultrasonic cleaning equipment comprises a base; driving motors are arranged on the left side and the right side of the base respectively, the driving motors are controlled by a control panel, the left side and the right side of the interior of the base are each provided with two sets of movement rails, and an auxiliary cleaning device is installed between the movement rails. The invention aims at solving the problems that in the capacitive touch screen technology, a touch screen is low in sensitivity, large in thickness and relatively large in weight, and a glass substrate is difficult to clean; the invention provides a capacitive touch screen production process and device.

Description

technical field [0001] The invention belongs to the field of capacitive touch screens, and in particular relates to a production process and device of a capacitive touch screen. Background technique [0002] The touch screen is a device that converts the sensing signal into a digital signal to realize human-computer interaction; among them, the capacitive touch screen is the capacitance change generated between the finger or the conductive medium and the electrode on the substrate when touching, through the digital signal of the driving chip. Convert and output the coordinate position of finger or conductive medium touch. [0003] At present, capacitive touch screens have been widely used in mobile phones, tablets and other fields. At present, the capacitive touch screen traditionally used is generally a structure in which two layers of glass are bonded through optical glue; or a structure in which one layer of glass and two or three layers of sensor film are bonded through...
