Abstract
Description

[0001] The present disclosure relates to the field of glass preparation, and in particular, to a glass thinning device. Background Art
[0002] With the development of portable electronic devices, mobile phones, tablets and other portable electronic devices are becoming more and more slender and thin, so it is necessary to manufacture thinner glass substrates. In order to manufacture thinner glass substrates, the methods currently used include physical thinning method and chemical thinning method, and the chemical thinning method is further subdivided into multi-piece vertical immersion method, single-piece vertical spraying method and waterfall flow method. Among them, when etching the glass substrate in the single-piece vertical spraying method, the etching liquid first contacts and reacts with the upper half of the glass substrate, and then contacts and reacts with the lower half of the glass substrate. From the perspective of reaction time, the reaction time of the upper half of the glass substrate is obviously longer than that of the lower half, so the upper and lower thicknesses of the etched glass substrate are uneven, resulting in poor glass surface quality. For example, a Chinese patent (publication number CN102161570B) discloses an upper downward spraying substrate etching device, including: a stacking component, a box having at least one substrate stacked vertically; a spraying component, spraying etching liquid on the upper part of the stacking component, and having at least one unit nozzle part formed in a direction parallel to the above-mentioned substrate.
