Problems solved by technology

[0009] Most of the existing production lines for the production of touch screen coated glass can only meet the coating of one kind of thin film material, but cannot meet the requirements of different processes for the coating of multiple thin film materials at the same time. Therefore, the production of different coated touch screens requires different production lines, and the cost is high

Abstract

The invention discloses a magnetron sputtering coating production line for capacitive touch screens. The magnetron sputtering coating production line comprises a vacuum coating cavity and a plurality of cavity supports, the vacuum coating cavity is arranged on the plurality of cavity supports, and an inner conveyer system is arranged inside the vacuum coating cavity. The vacuum coating cavity is sequentially divided into an inlet vacuum section, an inlet buffering vacuum section, an inlet transition vacuum section, a process coating vacuum section, an outlet transition vacuum section, an outlet buffering vacuum section and an outlet vacuum section. Each section is provided with an air sucking system respectively. The vacuum cavity is partitioned through gate valves, effective separation can be achieved, and process gas is stabilized. A conveying system adopts magnetic steering and is good in stability. The magnetron sputtering coating production line achieves continuous mass production of the capacitive touch screens and is high in production efficiency.

Description

technical field [0001] The invention relates to a capacitive touch screen magnetron sputtering coating production line. Background technique [0002] Capacitive touch screen is coated with a layer of transparent special conductive material on the glass surface. When a finger touches the glass, the capacitance of the contact will change, which will cause the frequency of the oscillator connected to it to change, and the determined touch position information can be obtained by measuring the frequency change. The working principle of the capacitive touch screen is: the capacitive touch screen is plated with narrow and long electrodes on the four sides of the touch screen, forming a low-voltage AC electric field in the conductor. When touching the screen, due to the electric field of the human body, a coupling capacitance will be formed between the finger and the conductor layer, and the current from the electrodes on the four sides will flow to the contacts, and the current st...
