Product quality; the acid-resistant gasket is set to leave a gap between the glass substrate and the PVC board to prevent the glass substrate from being adsorbed on the PVC board due to static force, and it is convenient to remove the glass substrate after thinning; because the two sides of the glass substrate are exposed Notch, so the thickness of the glass substrate can be measured, which is convenient for grasping the thinning process in time.

Description

An anti-fragment fixing device for single-sided thinning of glass substrates

technical field

The invention relates to the field of thinning production equipment for TFT-LCD liquid crystal glass, in particular to an anti-fragmentation fixing device for thinning one side of a glass substrate.

Background technique

Smartphones, tablet computers and other electronic products usually require thinning process for TFT-LCD liquid crystal glass substrates in order to obtain light and thin, increase light transmittance, and improve user experience. The process of thinning the glass substrate is mainly to insert the glass substrate into the etching basket, and react with the glass surface through the chemical solution, so as to achieve the purpose of thinning.

At present, the method of reducing the thickness of the glass substrate to less than 0.4mm is mainly adopted by one-sided thinning, which is to protect one side of the glass substrate and thin the other side. However, when performing single-sided thinning, as the thickness of the glass gradually becomes thinner, the glass substrate is bent or even broken due to gravity; in addition, when etching, the glass substrate needs to be fixed with clip bars and bottom teeth, and clip bars often appear after etching Quality problems such as printing and bottom tooth printing are more obvious, especially for G5 and above large-size panels that are thinned on one side.

Contents of the invention

The object of the present invention is to provide an anti-fragmentation fixing device for single-sided thinning of glass substrates, which can prevent glass substrates from bending and breaking when single-sided thinning, and can avoid clamping stripes and bottoms on the bottom of glass substrates. Tooth marks, improve product quality.

The technical solution adopted by the present invention to solve its technical problems is:

An anti-fragmentation fixing device for one-sided thinning of a glass substrate, comprising a PVC board adapted to the size of the glass substrate, an array of through holes is arranged on the PVC board, an array of acid-resistant gaskets is arranged on the front of the PVC board, and an array of acid-resistant gaskets is arranged on the back of the PVC board. Fixed frame; the array of through holes and the array of acid-resistant gaskets are distributed in staggered intervals; the two sides of the PVC board are respectively provided with notches; when in use, the side of the glass substrate covered with the acid-resistant film faces the front of the PVC board, and the through-holes are used to The array is used as a paste window, and the glass substrate is glued to the PVC board from the back of the PVC board with adhesive tape.

Further, the fixed frame includes two cross bars, the two cross bars are respectively arranged on the upper edge and the lower edge of the PVC board, and two vertical bars are connected between the two cross bars.

Further, the notch is semicircular, and the notch is located at 1/3 of the side of the PVC board from top to bottom.

The beneficial effect of the present invention is that the glass substrate is pasted on the non-deformable PVC board, and the shape of the PVC board is made firmer by fixing the frame, and then the whole body is inserted into the etching basket for thinning, so as to ensure that the glass substrate will not Bending fragments occur, and the bottom of the glass substrate is not in contact with the etched basket, so that there will be no clamping marks and bottom tooth marks, which improves product quality; the setting of the acid-resistant gasket leaves a gap between the glass substrate and the PVC board, Prevent the glass substrate from being adsorbed on the PVC board due to static force, and it is convenient to remove the glass substrate after thinning; because the two sides of the glass substrate expose the notches, the thickness of the glass substrate can be measured, which is convenient for timely grasping the thinning process.
