Glass single-side thinning method and glass thinning equipment

Abstract

The invention provides a glass single-face thinning method and glass thinning device.The glass single-face thinning device comprises a box body, an air cavity and an adsorption hole which are communicated are formed in an adsorption plate, a vacuum pump is fixedly arranged on the outer side of the adsorption plate and communicates with the air cavity, and the adsorption plate close to a first air cylinder is used for adsorbing a first glass plate; the adsorption plate close to the second air cylinder is used for adsorbing a second glass plate, a dust scraping device and a scrubbing device are arranged on the side, away from the reset spring, of the piston plate, a scraping plate in the dust scraping device can make movable contact with the first water absorption transmission belt, and a brush in the scrubbing device can make rotary contact with the first water absorption transmission belt. The invention provides a glass single-side thinning method and glass thinning equipment, which can simultaneously carry out thinning treatment on glass with different sizes, do not need to frequently adjust the position of the glass according to the height of the liquid level of etching liquid, also avoid the problem of uneven etching caused by bubbles in the etching liquid, and have a wider application range.

Description

technical field [0001] The invention relates to the technical field of glass thinning, in particular to a glass single-sided thinning method and glass thinning equipment. Background technique [0002] At present, the method of single-sided etching of the glass substrate is mainly: attach the acid-resistant film to the surface of the glass substrate that needs to be protected, and use an etching device to etch the treated glass substrate. After the treatment is completed, the acid-resistant film is protected. Peel off to achieve the effect of single-sided etching. [0003] In the prior art, the publication number is "CN106746705A", a glass single-sided thinning method and glass thinning equipment, the method includes the following steps: S1, the glass is detachably fixed on the fixed surface of the acrylic plate, and the glass The acid-resistant film faces the fixed surface of the acrylic plate; S2, moves the acrylic plate with the glass fixed into the etching tank to thin t...

Problems solved by technology

[0004] However, there are still obvious defects in its use: 1. The above-mentioned device adopts the method of moving the glass into the etching tank for thinning treatment, but in the process of thinning treatment, the etching solution will continue to decrease, resulting in liquid level In order to achieve the predetermined thinning thickness, it is necessary to continuously adjust the position of the glass, and there may be bubbles in the etching solution, which makes the thinning of the glass uneven and affects the quality of thinning; Placed in the etching tank, the glass will produce impurities during the thinning process. If the glass is placed horizontally, in order to protect the non-thinning surface of the glass, the etching solution needs to be relatively stable, so the dirt is easy to adhere to the thinning surface of the glass, resulting in etching. Impurities are difficult to remove, and the problem of reverse wear on the glass. If the glass is placed vertically, the etching solution that touches the upper glass will touch the lower glass again during the sliding process, resulting in uneven etching. Both have disadvantages
