Description

TECHNICAL FIELD

[0001] The application relates to the technical field of glass manufacturing, in particular to a glass strengthening device. BACKGROUND

[0002] The cover glass and display panel of a display screen are mostly made of chemically strengthened glass. When the glass is chemically strengthened, the glass is soaked in a high-temperature molten alkali bath salt (such as KNO3). Li + and Na + or K + in the bath salt are replaced, and the replacement of large ions causes the volume of the surface layer of the glass to expand, forming a dense compression layer on the surface of the glass after cooling. The compression layer on the surface layer forces the interior of the glass to be in a tensile stress state, forming a stress distribution of "external compression and internal tension", which significantly improves the impact and bending strength of the glass. However, the chemical strengthening method causes the alkali metal ions in the glass to diffuse into the bath salt, saturating the ion content in the bath salt and reducing the activity of the bath salt, thereby affecting the chemical strengthening effect on the glass.

[0003] In the conventional technology, a new bath salt is usually needed to restore the activity of the bath salt, but this method causes the glass production to stop, thereby affecting the production efficiency of the glass. CONTENT OF THE INVENTION

[0033] Please refer to Figures 1 to 2 One embodiment provides a glass strengthening device, comprising a chemical strengthening mechanism 100, a bath salt activation mechanism 200 and a conveying mechanism 300. The chemical strengthening mechanism 100 is provided with a strengthening cavity 111, a first inlet 112 and a first outlet 113 in communication, the strengthening cavity 111 is used to accommodate bath salt and glass; the bath salt activation mechanism 200 is provided with an activation cavity, a second inlet 210 and a second outlet 220 in communication, the activation cavity is used to accommodate an activity recovery agent, the second inlet 210 is in communication with the first outlet 113; the conveying mechanism 300 is used to convey the bath salt from the second outlet 220 to the first inlet 112.

[0034] The glass strengthening device can accommodate the bath salt and the glass in the strengthening cavity 111 of the chemical strengthening mechanism 100, the alkali metal ions on the surface of the glass in the strengthening cavity 111 can displace the alkali metal ions with a larger radius in the bath salt, so as to improve the impact resistance and bending strength of the glass; when the bath salt in the strengthening cavity 111 is saturated in ion content and the chemical strengthening effect is weakened, the bath salt sequentially passes through the first outlet 113 and the second inlet 210 into the activation cavity of the bath salt activation mechanism 200, the active recovery agent in the activation cavity can react with the bath salt to restore the activity of the bath salt, and then restore the chemical strengthening effect of the bath salt, the bath salt restored in activity is discharged through the second outlet 220 to the conveying mechanism 300, the conveying mechanism 300 conveys the bath salt to the first inlet 112, and the bath salt restored in activity returns to the strengthening cavity 111 through the first inlet 112 to improve the activity of the bath salt in the strengthening cavity 111; compared with the prior art, the glass strengthening device can improve the activity of the bath salt in the strengthening cavity 111 while strengthening the glass, so that the glass production is not stopped, and the production efficiency of the glass is improved.

[0035] As an explanation, the glass and the bath salt in the strengthening cavity 111 can have a displacement reaction, the Li + in the surface layer of the glass displaces the Na + or K + in the bath salt with a larger radius, so that the volume of the surface layer of the glass expands, and the surface layer of the glass after cooling forms a dense compression layer, the compression layer of the surface layer forces the glass inside to be in a state of tensile stress, and then the strength of the glass is improved; however, after the glass and the bath salt react for a long time, the content of Li + in the bath salt is saturated, so that the chemical strengthening effect of the bath salt is greatly reduced, and the active recovery agent in the activation cavity can restore the activity of the bath salt, and the conveying mechanism 300 conveys the bath salt restored in activity back to the strengthening cavity 111, so as to continue to strengthen the glass.

[0036] Further, in the above embodiment, part of the bath salt in the strengthening cavity 111 can also flow circularly between the strengthening cavity 111, the activation cavity and the conveying mechanism 300 while the bath salt reacts with the glass, so that when the activity of the bath salt decreases, the glass strengthening device can continuously restore the activity of the bath salt, so as to avoid the glass production from being stopped and affecting the production efficiency of the glass.

[0037] In one embodiment, the active recovery agent includes an ion sieve containing a high-concentration bath salt (such as NaNO3), and the Na element in the ion sieve can exchange ions with Li + in the bath salt, so as to restore the activity of the bath salt.

[0038] In other embodiments, the active recovery agent can also be sodium phosphate, and the sodium phosphate can react with the cations (such as Li +) to generate a precipitate, and thereby restore the activity of the bath salt.

[0042] Further, the communication hole is provided with at least two spaced-apart cages, thereby further improving the reaction effect of the activity restorer and the bath salt in the activation chamber.

[0043] In one embodiment, the glass strengthening device further comprises a moving mechanism, which is arranged in the bath salt activation mechanism 200, and the cage is connected with the moving mechanism, and the moving mechanism can drive the cage to reciprocate between above and below the liquid level of the bath salt.

[0044] In this way, the moving mechanism drives the cage to move above the liquid level of the bath salt, so as to facilitate the addition or replacement of the activity restorer in the cage, and after the addition or replacement of the activity restorer is completed, the moving mechanism drives the cage to move below the liquid level of the bath salt, so that the activity restorer can react with the bath salt to restore the activity of the bath salt.

[0045] In one embodiment, the moving mechanism comprises a mechanical arm, which is connected with the cage to drive the cage to reciprocate between above and below the liquid level of the bath salt.

[0046] In another embodiment, the moving mechanism comprises a guide rail and a guide piece, the guide rail is arranged on the side wall of the activation chamber and can extend along the height direction of the liquid level of the bath salt, the guide piece is movably arranged on the guide rail, and the cage is connected with the guide piece, so that when the guide piece moves on the guide rail, the cage can be driven to move.

[0047] In other embodiments, the moving mechanism can also be an automatic lifting handle, and the like, which will not be described here.
