Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of substrate production, and in particular relates to glass substrate forming and processing equipment. Background Art
[0002] The molten overflow method is a mainstream technology used to manufacture glass substrates. Its main feature is its ability to produce ultra-thin glass substrates with double pristine glass surfaces. This allows for the omission of post-processing steps such as grinding or polishing, thereby avoiding surface defects caused by media contact. The overflow method involves flowing molten glass through a platinum channel into an overflow brick. The glass then flows down the sides of the overflow brick and converges at a tapered point, where it is pulled by rollers below to form a glass sheet.
[0003] However, due to development needs, the size of glass substrates is required to be larger and larger. In order to obtain larger glass substrates, the width of the overflow bricks needs to be extended to increase the width of the glass substrates. However, this results in uneven heat dissipation of the molten glass as it flows along the overflow bricks during production. The temperature on the two outer sides drops too quickly, causing the fluidity of the glass liquid in this part to deteriorate. Ultimately, when pulling the glass substrate, the thickness is uneven.
[0004] Therefore, it is urgent to design a glass substrate forming and processing equipment to solve the technical problem of uneven thickness of the glass plate during traction caused by the uneven heat dissipation of the molten glass liquid.
[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Utility Model Content

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0038] Research has revealed that the molten overflow method is a mainstream technology for manufacturing glass substrates. Its main feature is its ability to produce ultra-thin glass substrates with double pristine glass surfaces. This allows for the omission of post-processing steps such as grinding or polishing, thereby avoiding surface defects caused by media contact. The overflow method involves flowing molten glass through a platinum channel into an overflow brick. The glass then flows down the sides of the brick and converges at a tapered point, where it is pulled by rollers below to form a glass sheet.
[0039] However, due to development needs, the size of glass substrates is required to be larger and larger. In order to obtain larger glass substrates, the width of the overflow bricks needs to be extended to increase the width of the glass substrates. However, this results in uneven heat dissipation of the molten glass as it flows along the overflow bricks during production. The temperature on the two outer sides drops too quickly, causing the fluidity of the glass liquid in this part to deteriorate. Ultimately, when pulling the glass substrate, the thickness is uneven.
[0040] Therefore, it is urgent to design a glass substrate forming and processing equipment to solve the technical problem of uneven heat dissipation of the molten glass liquid causing uneven thickness of the glass plate during traction.
[0041] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.
[0042] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe the technical content.
[0043] Based on the above research, in order to solve the above technical problems, refer to Figure 1At least one embodiment provides a glass substrate forming and processing apparatus comprising: an overflow box 1, two heating plates 2, and pulling rollers 3. The overflow box 1 is adapted to temporarily store molten glass. The overflow box 1 has overflow ports 11 on either side, and a tip 12 at the bottom. When the level of the temporarily stored molten glass in the overflow box 1 exceeds the level of the overflow ports 11, the molten glass overflows from the overflow ports 11 and flows along the sidewalls of the overflow box 1 to the tip 12 at the bottom of the overflow box 1. The two heating plates 2 are disposed below the overflow box 1. The pulling rollers 3 are located at the ends of the heating plates 2 and extend to either side of the tip 12. When the molten glass overflows to the tip 12, the two pulling rollers 3 pull and shape the molten glass, allowing it to continue its downward movement and form a glass sheet. The heating plates 2 heat the molten glass on the pulling rollers 3 and on both sides of the tip 12 as the glass overflows to the tip 12, ensuring good fluidity and uniform flow of the molten glass, thereby resulting in a uniform thickness of the formed glass sheet.
[0044] Reference Figure 1 and Figure 3 In some embodiments, the glass substrate forming and processing equipment further includes a housing 6, and the overflow box 1 and the heating plate 2 are both mounted on the housing 6. A delivery pipe 5 is provided on one side of the overflow box 1, which is in communication with the inner cavity of the overflow box 1 and is suitable for delivering molten glass liquid into the inner cavity of the overflow box 1. The overflow box 1 includes a box body 13, the outer wall of the box body 13 is divided into an overflow section 14 and a confluence section 15, two overflow ports 11 are respectively located at the top of the overflow section 14, and the tip 12 is located at the bottom of the confluence section 15. After the glass liquid overflows from the overflow port 11, it first flows along the overflow section 14, and then flows along the confluence section 15 to the tip 12. The arrangement of the above components achieves the effect of delivering and overflowing the glass liquid.
[0045] Reference Figure 2 In some embodiments, in order to thin thicker molten glass, a scraper 4 is provided above the heating plate 2. The scraper 4 is spaced apart from the bottom of the overflow box 1, and the tip 12 of the scraper 4 extends toward the bottom of the overflow box 1, so that before the molten glass flows from the bottom side wall to the tip 12, the scraper 4 can thin the molten glass that is locally thickened due to uneven flow.
[0046] Reference Figure 2 In some embodiments, in order to reuse the molten glass scraped off by the scraper 4, the heating plate 2 has ribs 21 on both sides to collect the molten glass scraped off by the scraper 4 on the heating plate 2. Since the heating plate 2 is arranged at an angle and the end of the heating plate 2 is lower, the molten glass will flow toward the pulling roller 3 at the end of the heating plate 2. In order to allow the molten glass to flow to the pulling roller 3 for reuse, the scraper 4 is spaced apart from the heating plate 2 to prevent the scraper 4 from blocking the flow of the molten glass, thereby achieving this effect.
[0047] Reference Figure 2In some embodiments, in order to make the glass liquid scraped by the scraper 4 flow quickly to the heating plate 2, the angle between the scraper 4 and the horizontal plane is 75-90°. Preferably, the angle between the scraper 4 and the horizontal plane is 90° to ensure the flow speed of the glass liquid. It can be optionally 75° to avoid the glass liquid flowing too slowly and being unable to match the flow speed on the overflow box 1.
[0048] Reference Figure 1 At least one embodiment further provides a glass substrate forming and processing apparatus, comprising: an overflow box 1, two heating plates 2, and pulling rollers 3. The overflow box 1 is suitable for temporarily storing molten glass. The overflow box 1 has overflow ports 11 on both sides, and a tip 12 at the bottom of the overflow box 1. When the level of the temporarily stored glass in the overflow box 1 is higher than the level of the overflow ports 11, the glass overflows from the overflow ports 11 and flows along the side walls of the overflow box 1 to the tip 12 at the bottom of the overflow box 1. The two heating plates 2 are disposed below the overflow box 1. The pulling rollers 3 are located at the ends of the heating plates 2, and the two pulling rollers 3 extend to either side of the tip 12. When the glass overflows to the tip 12, the two pulling rollers 3 pull and shape the glass, causing it to continue moving downward to form a glass sheet. During the process of the glass overflowing to the tip 12, the heating plates 2 are suitable for heating the pulling rollers 3 and the glass on both sides of the tip 12, ensuring good fluidity and uniform flow of the glass. A scraper 4 is positioned above the heating plate 2, with its tip 12 extending toward the bottom of the overflow box 1 to scrape away thicker molten glass. The scraper 4 is spaced from the bottom of the overflow box 1, and ribs 21 are located on either side of the heating plate 2 to collect the scraped molten glass and direct it to the pulling rollers 3 for reuse. These components, combined with the heating plate 2 to heat the molten glass on both sides of the pulling rollers 3 and the tip 12, ensure good fluidity and uniform flow. The molten glass is then pulled and shaped by the pulling rollers 3, resulting in a uniform thickness of the formed glass sheet.
