[0002] The current folding screen uses ultra-thin glass materials for flexible cover plates, and chemical tempering is an indispensable part of the strengthening process of flexible materials. Therefore, the future development trend of folding screens will be to use ultra-thin glass as a flexible cover plate for module assembly and mass production. In order to improve the strength of the ultra-thin glass cover plate, potassium nitrate in a high-temperature molten state is often used to replace sodium and potassium ions to achieve the purpose of chemical tempering. However, due to its ultra-thin and soft characteristics, ultra-thin flexible glass cannot stand in the tempering liquid for tempering, so a chemical tempering device suitable for ultra-thin flexible glass is required. The device currently used is to clamp and limit the glass, which has a high risk of breakage. After the device tempers a batch of glass each time, the tempering salt in the tempering liquid will be taken away from the tempering liquid furnace along with the device, resulting in a waste of tempering salt, resulting in a large amount of replenishment, a large demand, high cost, and low cost performance. In addition, the device has serious salt accumulation, which will cause serious mark defects and seriously affect the process yield and mass production output.

The tool is placed in a tempering furnace to temper the glass, the mounting frame and the support bar are made of high temperature resistant materials, the support bar can be detachably installed in the mounting frame, and a plurality of the support bars are arranged in a horizontal and vertical interval to form an independent chamber for storage, the size of the independent chamber is still determined by the size of the foldable glass, when it is necessary to temper glass similar to the size of a mobile phone screen, the horizontal and vertical intervals between the plurality of the support bars are relatively small, and when it is necessary to temper glass similar to the size of a flat screen, the horizontal and vertical intervals between the plurality of the support bars are relatively large.

[0022] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connection relationships of the components involved, the functions and working principles of the components, etc., by referring to the accompanying drawings:

[0023] As attached Figure 1 , Attachment Figure 2As shown, the utility model is a chemical tempering treatment device for ultra-thin flexible glass. A support member 2 is arranged on the device frame 1. A plurality of protruding teeth 3 are arranged on the support member 2 according to the gap.

The gaps 5 between two adjacent teeth 3 are respectively wound with a gap high-temperature wire 6. The surface of the gap high-temperature wire 6 is a convex arc surface structure. The above structure proposes an improved technical solution to the deficiencies in the prior art. When the structure is set, support members are respectively arranged on the upper and lower parts of the device frame. A plurality of protruding teeth 3 are arranged in the gap on the support member. The teeth are formed by bending a rod made of high-temperature resistant stainless steel material, and then welded to the support member. The sides of each tooth 3 are respectively wound with a tooth high-temperature wire 4. The gaps 5 between two adjacent teeth 3 are respectively wound with a gap high-temperature wire 6. That is to say, each tooth has two symmetrically arranged tooth high-temperature wires 4, and the gap between two adjacent teeth has a gap high-temperature wire 6. The two tooth high temperature wires 4 of two adjacent teeth and the gap high temperature wire 6 between two adjacent teeth are used to limit the edge of one side of an ultra-thin flexible glass. When each piece of ultra-thin flexible glass 11 is clamped and limited, the top of the ultra-thin flexible glass 11 is against the gap high temperature wire 6 of the gap 5 of the corresponding support member at the upper part, one side of the ultra-thin flexible glass 11 contacts the tooth high temperature wire 4 on the side of one upper tooth 9, and the other side of the ultra-thin flexible glass 11 contacts the tooth high temperature wire 4 on the side of another upper tooth 9. The top of the ultra-thin flexible glass 11 realizes linear contact at three locations instead of surface contact, thereby reducing the contact area. On the one hand, the contact area between the ultra-thin flexible glass and the device is reduced, and the vibration process reduces the damage caused by the collision between the glass and the corresponding clamping and limiting locations, thereby effectively reducing the risk of glass breakage in the tempering liquid. On the other hand, it is convenient for the tempering liquid to flow through the gap between the device and the glass, greatly reducing the tempering liquid taken out of the tempering furnace by the device each time, reducing the waste of tempering liquid, reducing costs, and at the same time reducing the mark of the chemical tempering process of the ultra-thin glass to ensure good process stability, improve mass production efficiency, and increase mass production capacity. The ultra-thin flexible glass chemical tempering treatment device described in the utility model has a simple structure, can reliably realize the clamping and limiting of the ultra-thin flexible glass during the tempering process, reduce the breakage of the ultra-thin flexible glass, and at the same time greatly reduce the tempering liquid taken out of the tempering furnace by the tempering device each time, reduce the problem of salt accumulation, and reduce the mark of the ultra-thin glass during the chemical tempering process, thereby improving the yield.

In the above structure, the latching teeth are made of high temperature and salt resistant metal materials such as stainless steel, and are arc-shaped structures. A latching tooth high temperature wire 4 is set on each side of each latching tooth. The latching tooth high temperature wire 4 is a structure protruding from the surface of the latching teeth. In this way, the glass is clamped by the latching tooth high temperature wires 4 on both sides, and they are in linear contact with each other.

That is to say, there are two symmetrically arranged tooth high-temperature wires 4 on each tooth, and a gap portion high-temperature wire 6 is arranged at the gap portion between two adjacent teeth.

The top of the ultra-thin flexible glass 11 realizes linear contact at three locations instead of surface contact, thereby reducing the contact area. On the one hand, the contact area between the ultra-thin flexible glass and the device is reduced, and the vibration process reduces the damage caused by the collision between the glass and the corresponding clamping and limiting parts, thereby effectively reducing the risk of glass damage in the tempering liquid. On the other hand, it is convenient for the tempering liquid to flow through the gap between the device and the glass, greatly reducing the tempering liquid taken out of the tempering furnace each time by the device, reducing the waste of tempering liquid, reducing costs, and at the same time reducing the imprint of the ultra-thin glass during the chemical tempering process to ensure good process stability, improve mass production efficiency, and increase mass production capacity.
