Description

Technical Field

[0001] The present invention belongs to the technical field of ultra-thin flexible glass, and more specifically, relates to an ultra-thin flexible glass stacking method. The present invention also relates to an ultra-thin flexible glass stacking structure. Background Art

[0002] As ultra-thin flexible glass is a development trend of folding screens, it is very important to ensure the production efficiency and yield of the product. Due to its ultra-thin characteristics, the processing of single-body ultra-thin flexible glass is extremely difficult, and the single-body is usually produced by stacking. The disadvantages of the existing technology are: the current ultra-thin flexible glass raw materials need to be thinned, and the clamping edges of the thinning tooling are waste after thinning. This part of the waste usually needs to be laser cut before stacking. The edge strength of the ultra-thin flexible glass (ultra-high glass) will be reduced after the laser cutting of the product edge due to high-energy impact. Therefore, it is very easy to have the risk of damage during stacking operations. At the same time, when laser cutting is performed, some defects will be added to the surface of the product. Therefore, the existing technology affects the quality of ultra-thin flexible glass.

[0003] In the prior art, there is a technology named "Ultra-thin flexible glass preparation method and ultra-thin flexible glass" and the publication (announcement) number is "CN118908582A", which discloses a method for preparing ultra-thin flexible glass, including the steps: S1, preparing a pattern on a glass substrate; S2, etching the glass substrate; S3, thinning the glass substrate as a whole; S4, stacking the glass substrates to form a main stack; S5, cutting the main stack to obtain a sub-stack; S6, machining the sub-stack; S7, etching the edge of the sub-stack; S8, tempering; S9, surface etching; S10, cleaning. The method for preparing ultra-thin flexible glass of the present invention has a reasonable process route, a very high yield rate in the production process, and the finished glass has high impact resistance and mass production, which can effectively solve the problem of insufficient strength in the bending zone of conventional unequal thickness products in the current UTG and development process, and at the same time improve the strength of the non-bending zone of UTG. The present invention also discloses an ultra-thin flexible glass.

[0004] However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the invention

[0005] The technical problem to be solved by the present invention is: in view of the shortcomings of the prior art, a method for stacking ultra-thin flexible glass is provided which has simple steps and directly performs a stacking process after the ultra-thin flexible glass is thinned, thereby effectively improving product production efficiency and reducing the risk of product damage in the stacking process.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is:

[0007] The present invention is a method for stacking ultra-thin flexible glass, and the stacking steps of the method for stacking ultra-thin flexible glass are as follows:

[0008] S1. A lower cover glass, an upper cover glass and an ultra-thin flexible glass are provided, and clamping edges are provided on both sides of the ultra-thin flexible glass along the width direction. The lower cover glass and the upper cover glass have the same shape, length and width, and the width of the lower cover glass is smaller than the width of the ultra-thin flexible glass;

[0009] S2. Place the lower cover glass at the bottom, apply glue on the lower cover glass to form a glue layer 5, and then place a piece of ultra-thin flexible glass on the glue layer 5 above the lower cover glass after applying glue, with the clamping edge of the ultra-thin flexible glass exposed to the outside of the lower cover glass in the width direction;

[0010] S3. The ultra-thin flexible glass is placed and rolled, and after rolling, the ultra-thin flexible glass 3 is spot-cured at the edge of the rolling position; after spot curing, the ultra-thin flexible glass above is coated with glue to form a glue layer, and then the ultra-thin flexible glass is placed on the glue layer, and then rolled and spot-cured;

[0011] S4. After the ultra-thin flexible glass is stacked to the required number of layers, glue is applied on the top layer of ultra-thin flexible glass to form a glue layer, and then the upper cover glass is placed on the glue layer, and then rolled. There is no need for spot curing, and the entire laminated glass assembly is directly cured. After the curing is completed, the stacking process is completed.

[0012] After the ultra-thin flexible glass is stacked to the required number of layers, the clamping edges of each piece of ultra-thin flexible glass are exposed outside the lower cover glass and the upper cover glass along the width direction.

[0013] After the ultra-thin flexible glass is stacked to the required number of layers, the clamping edges of the multiple sheets of ultra-thin flexible glass are flush along the vertical direction; the upper glass cover plate and the lower glass cover plate are flush along the vertical direction.

[0014] After the entire laminated glass assembly is solidified and there is no need to clamp the ultra-thin flexible glass, the laser cutting machine performs laser cutting on the clamping portion on each side of the ultra-thin flexible glass of the laminated glass assembly.

[0015] The length dimension of the lower cover glass is equal to the length dimension of the ultra-thin flexible glass.

[0016] After the ultra-thin flexible glass is stacked to the required number of layers, each side edge of the multiple pieces of ultra-thin flexible glass along the length direction is flush in the vertical direction; each side edge of the lower glass cover plate and the upper glass cover plate along the length direction is flush in the vertical direction.

[0017] Each side edge of the upper glass cover plate and the ultra-thin flexible glass along the length direction is in a flush state along the vertical direction.

[0018] The present invention also relates to an ultra-thin flexible glass stacking structure, comprising a lower glass cover plate, an upper glass cover plate, and multiple pieces of ultra-thin flexible glass. The ultra-thin flexible glass is provided with clamping edges on both sides along the width direction. The lower cover glass and the upper cover glass have the same shape, length and width. The width dimension of the lower cover glass 1 is smaller than the width dimension of the ultra-thin flexible glass.

[0019] The ultra-thin flexible glass stacking structure also includes multiple layers of glue layers, multiple layers of ultra-thin flexible glass are arranged between the lower glass cover plate and the upper glass cover plate, a glue layer is arranged between the bottommost layer of ultra-thin flexible glass and the bottom glass cover plate, a glue layer is arranged between the topmost layer of ultra-thin flexible glass and the upper glass cover plate, and glue layers are arranged between adjacent ultra-thin flexible glasses.

[0020] After the lower glass cover plate, the upper glass cover plate, the ultra-thin flexible glass, and the adhesive layer are stacked to the required number of layers to form a laminated glass assembly, the multiple pieces of ultra-thin flexible glass are flush along the vertical direction on each side along the width direction; the lower glass cover plate and the upper glass cover plate are flush along the vertical direction on each side along the width direction.

[0021] The technical solution of the present invention is adopted, and the working principle and beneficial effects are as follows:

[0022] The ultra-thin flexible glass stacking structure of the present invention aims to provide a stacking method of ultra-thin flexible glass (ultra-thin glass): due to the characteristics of ultra-thin flexible glass, a cover glass with higher strength is required to protect the ultra-thin flexible glass during the stacking process, and the method of the present invention does not require a laser cutting process for a single piece of ultra-thin flexible glass, so the size (length and / or width) of the cover glass should be smaller than the size of the ultra-thin flexible glass, that is, the size of the cover glass is the size of the ultra-thin flexible glass after thinning and removing the clamping edge. In this way, after the ultra-thin flexible glass and the cover glass are stacked, the clamping edge of the ultra-thin flexible glass is exposed outside the side of the cover glass. The specific process flow for stacking is as follows: first place a piece of cover glass at the bottom, then apply glue on the cover glass to form a glue layer, and after applying glue, place the ultra-thin flexible glass on top of the glue layer above the cover glass. It should be noted that the ultra-thin flexible glass should be placed so that the clamping edge is exposed on the outside of the side of the cover glass, and then rolling is performed. Rolling can evenly distribute the glue of the glue layer on the ultra-thin flexible glass, so that the product has good flatness and is convenient for subsequent processing. After rolling, spot curing is performed on the edge of the rolling position of the product. The main function is to prevent the next rolling from causing product deviation; after spot curing, continue to apply glue, place glass, roll, and spot cure. After the glass is stacked to the required number of layers, apply glue on the top layer of the ultra-thin flexible glass and place a piece of cover glass. After rolling, there is no need for spot curing, and the entire laminated product is directly cured. After curing is completed, the entire stacking process ends. The laser cutting process of the clamping edge of the waste ultra-thin flexible glass is changed to when the glass does not need to be clamped. The clamping edge of the ultra-thin flexible glass protrudes from the outside of the cover glass, and multiple sheets of ultra-thin flexible glass overlap up and down, so the clamping parts of multiple sheets of ultra-thin flexible glass of a laminated glass assembly can be cut synchronously at one time, thereby improving the cutting efficiency. At this time, the ultra-thin flexible glass no longer needs to be clamped and is no longer impacted by the high energy generated during the stacking process, and laser cutting will not affect the quality of the glass. In summary, the present invention is superior to the traditional stacking method in terms of processing efficiency, reduction of damage risk, and apparent yield. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is a further detailed description of the specific implementation of the present invention, such as the shape, structure, mutual position and connection relationship between the various components involved, the function and working principle of each part, etc., through the description of the embodiments with reference to the accompanying drawings:

[0029] As attached Figure 1 -Attached Figure 3 As shown, the present invention is a method for stacking ultra-thin flexible glass, and the stacking steps of the method for stacking ultra-thin flexible glass are:

[0030] S1. Arrange a lower cover glass 1, an upper cover glass 2 and an ultra-thin flexible glass 3, and respectively arrange clamping edges 4 on both sides of the ultra-thin flexible glass 3 along the width direction. The lower cover glass 1 and the upper cover glass 2 have the same shape, length and width, and the width dimension of the lower cover glass 1 is smaller than the width dimension of the ultra-thin flexible glass 3; S2. Place the lower cover glass 1 at the bottom, apply glue on the lower cover glass 1 to form a glue layer 5, and then place a piece of ultra-thin flexible glass 3 on the glue layer 5 above the lower cover glass 1 after applying glue, and the clamping edges 4 of the ultra-thin flexible glass 3 are exposed outside the lower cover glass 1 along the width direction; S3. Roll the placed ultra-thin flexible glass 3 to make the glue layer 5 evenly Evenly distributed on the ultra-thin flexible glass 3, so that the product has good flatness and is convenient for subsequent processing. After rolling, spot curing is performed on the edge of the rolling position of the ultra-thin flexible glass 3. The main function of spot curing is to prevent the next rolling from causing product deviation; after spot curing, glue is applied on the upper ultra-thin flexible glass 3 to form a glue layer 5, and then the ultra-thin flexible glass 3 is placed on the glue layer 5, and then rolled and spot cured; S4. After the ultra-thin flexible glass 3 is stacked to the required number of layers, glue is applied on the uppermost ultra-thin flexible glass 3 to form a glue layer 5, and then the upper cover glass 2 is placed on the glue layer 5, and then rolled. There is no need to perform spot curing, and the entire laminated glass assembly formed is directly cured. After curing is completed, the stacking process ends. The above steps propose an improved technical solution to address the deficiencies in the prior art. The traditional stacking method requires that after a single piece of ultra-thin flexible glass is thinned, a single piece is first laser cut to remove the clamping edge of the ultra-thin flexible glass, and then the operation process of gluing, rolling, and curing is carried out. However, the edge strength of the ultra-thin flexible glass after laser cutting is relatively low. During the stacking process, it is very easy to cause product damage during the rolling operation. Secondly, during laser cutting, since laser cutting is performed on a single body, it will also cause some surface defects on the surface of the ultra-thin flexible glass, and single-piece laser cutting leads to slower production efficiency. The purpose of the present invention is to provide a stacking method of ultra-thin flexible glass (ultra-thin glass): due to the characteristics of ultra-thin flexible glass, a cover glass with higher strength is required to protect the ultra-thin flexible glass during the stacking process, and the method of the present invention does not require a laser cutting process for a single piece of ultra-thin flexible glass, so the size of the cover glass (length and / or width) should be smaller than the size of the ultra-thin flexible glass, that is, the size of the cover glass is the size of the thinned ultra-thin flexible glass after removing the clamping edge. In this way, after the ultra-thin flexible glass and the cover glass are stacked, the clamping edge of the ultra-thin flexible glass is exposed on the outside of the side of the cover glass.The specific process flow for stacking is as follows: first place a piece of cover glass at the bottom, then apply glue on the cover glass to form a glue layer, and after applying glue, place the ultra-thin flexible glass on top of the glue layer above the cover glass. It should be noted that the ultra-thin flexible glass should be placed so that the clamping edge is exposed on the outside of the side of the cover glass, and then rolling is performed. Rolling can evenly distribute the glue of the glue layer on the ultra-thin flexible glass, so that the product has good flatness and is convenient for subsequent processing. After rolling, spot curing is performed on the edge of the rolling position of the product. The main function is to prevent the next rolling from causing product deviation; after spot curing, continue to apply glue, place glass, roll, and spot cure. After the glass is stacked to the required number of layers, apply glue on the top layer of the ultra-thin flexible glass and place a piece of cover glass. After rolling, there is no need for spot curing, and the entire laminated product is directly cured. After curing is completed, the entire stacking process ends. The laser cutting process of the clamping edge of the waste ultra-thin flexible glass is changed to when the glass does not need to be clamped. The clamping edge of the ultra-thin flexible glass protrudes from the outside of the cover glass, and multiple pieces of ultra-thin flexible glass overlap up and down, so the clamping parts of multiple pieces of ultra-thin flexible glass of a laminated glass assembly can be synchronously cut at one time, thereby improving the cutting efficiency. At this time, the ultra-thin flexible glass no longer needs to be clamped, and is no longer impacted by the high energy generated by the stacking process, and laser cutting will not affect the quality of the glass. In summary, the present invention is superior to traditional stacking methods in terms of processing efficiency, reducing the risk of damage, and apparent yield. The ultra-thin flexible glass stacking method described in the present invention has simple steps, and the stacking process is directly carried out after the ultra-thin flexible glass is thinned, which effectively improves the product production efficiency and reduces the risk of damage to ultra-thin flexible products in the stacking process.

[0031] After the ultra-thin flexible glass 3 is stacked to the required number of layers, the clamping edge 4 of each piece of ultra-thin flexible glass 3 is exposed outside the lower cover glass 1 and the upper cover glass 2 along the width direction. In the above structure, since the ultra-thin flexible glass needs to be clamped from both sides of the glass by the clamp, clamping edges are provided on both sides of the ultra-thin flexible glass for clamping. When the glass is clamped, it is clamped from both sides in the width direction, and the clamping edges are clamped during clamping, which does not affect the quality of the glass itself. After completing the specific process, the stacked glass assembly is laser cut.

[0032] After the ultra-thin flexible glass 3 is stacked to the required number of layers, the side edges of the clamping edges 4 of the multiple sheets of ultra-thin flexible glass 3 are in a flush state along the vertical direction; the side edges of the upper glass cover plate 1 and the lower glass cover plate 2 are in a flush state along the vertical direction. In the above structure, the multiple sheets of ultra-thin flexible glass 3 are in a flush state, which, on the one hand, ensures the stacking quality and facilitates the subsequent processing of the laminated glass assembly as a whole, and on the other hand, facilitates the subsequent cutting of the clamping edges as a whole, thereby effectively ensuring the cutting accuracy, and only cutting the clamping edges without affecting the glass itself.

[0033] After the entire laminated glass assembly is solidified, when there is no need to clamp the ultra-thin flexible glass, the laser cutting machine performs laser cutting on the clamping portion 4 on each side of the ultra-thin flexible glass 3 of the laminated glass assembly. In the above structure, the ultra-thin flexible glass is not cut without cutting the clamping edge, but is not cut immediately after thinning, nor is it cut in a single piece, but is cut in the subsequent links, and each stacked glass assembly is cut as a whole, which will not affect product quality and effectively improve efficiency.

[0034] The length dimension of the lower cover glass 1 is equal to the length dimension of the ultra-thin flexible glass 3. After the ultra-thin flexible glass 3 is stacked to the required number of layers, each side edge of the multiple sheets of ultra-thin flexible glass 3 along the length direction is in a flush state in the vertical direction; each side edge of the lower glass cover 1 and the upper glass cover 2 along the length direction is in a flush state in the vertical direction. The upper glass cover 1 and the ultra-thin flexible glass 3 along the length direction are in a flush state in the vertical direction. With the above structure, multiple sheets of ultra-thin flexible glass are also flush in the length direction. When the ultra-thin flexible glass is stacked, the glass is stacked by a robotic arm / robot, which effectively guarantees the precise control of the glass placement position, ensures the flushness of the ultra-thin flexible glass, and facilitates subsequent overall cutting.

[0035] The present invention also relates to an ultra-thin flexible glass stacking structure, comprising a lower glass cover plate 1, an upper glass cover plate 2, and multiple sheets of ultra-thin flexible glass 3, wherein clamping edges 4 are respectively arranged on both sides of the ultra-thin flexible glass 3 along the width direction, and the lower cover plate glass 1 and the upper cover plate glass 2 have the same shape, length and width, and the width dimension of the lower cover plate glass 1 is smaller than the width dimension of the ultra-thin flexible glass 3. The ultra-thin flexible glass stacking structure further comprises multiple layers of adhesive layers 5, wherein multiple layers of ultra-thin flexible glass 3 are arranged between the lower glass cover plate 1 and the upper glass cover plate 2, an adhesive layer 5 is arranged between the lowermost ultra-thin flexible glass 3 and the lower glass cover plate 1, an adhesive layer 5 is arranged between the uppermost ultra-thin flexible glass 3 and the upper glass cover plate 2, and an adhesive layer 5 is arranged between adjacent ultra-thin flexible glasses 3. After the lower glass cover plate 1, the upper glass cover plate 2, the ultra-thin flexible glass 3, and the adhesive layer 5 are stacked to the required number of layers to form a laminated glass assembly, the multiple sheets of ultra-thin flexible glass 3 are in a flush state along the vertical direction on each side along the width direction; the lower glass cover plate 1 and the upper glass cover plate 2 are in a flush state along the vertical direction on each side along the width direction.

[0036] The ultra-thin flexible glass stacking structure of the present invention aims to provide a stacking method of ultra-thin flexible glass: due to the characteristics of ultra-thin flexible glass, a cover glass with higher strength is required to protect the ultra-thin flexible glass during the stacking process, and the method of the present invention does not require a laser cutting process for a single piece of ultra-thin flexible glass, so the size (length and / or width) of the cover glass should be smaller than that of the ultra-thin flexible glass, that is, the size of the cover glass is the size of the thinned ultra-thin flexible glass after removing the clamping edge. In this way, after the ultra-thin flexible glass and the cover glass are stacked, the clamping edge of the ultra-thin flexible glass is exposed outside the side of the cover glass. The specific process flow for stacking is as follows: first place a piece of cover glass at the bottom, then apply glue on the cover glass to form a glue layer. After applying glue, place the ultra-thin flexible glass on top of the glue layer above the cover glass. Note that the ultra-thin flexible glass should be placed so that the clamping edge is exposed on the outside of the side of the cover glass. Then roll it. Rolling can evenly distribute the glue of the glue layer on the ultra-thin flexible glass, so that the product has good flatness and is convenient for subsequent processing. After rolling, spot curing is performed on the edge of the rolling position of the product. The main function is to prevent the next rolling from causing product deviation. After spot curing, continue to apply glue, place glass, roll, and spot cure. After the glass is stacked to the required number of layers, apply glue on the top layer of the ultra-thin flexible glass and place a piece of cover glass. After rolling, there is no need for spot curing. The entire laminated product is directly cured. After curing is completed, the entire stacking process ends. The laser cutting process of the clamping edge of the waste ultra-thin flexible glass is changed to when the glass does not need to be clamped. The clamping edge of the ultra-thin flexible glass protrudes from the outside of the cover glass, and multiple sheets of ultra-thin flexible glass overlap up and down, so that the synchronous cutting of the clamping parts of multiple sheets of ultra-thin flexible glass of a laminated glass assembly can be completed at one time, thereby improving the cutting efficiency. At this time, the ultra-thin flexible glass no longer needs to be clamped and is no longer impacted by the high energy generated during the stacking process, and laser cutting will not affect the quality of the glass. In summary, the present invention is superior to the traditional stacking method in terms of processing efficiency, reduction of damage risk, and apparent yield.

[0037] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
