Abstract
Description
Technical Field
[0001] This invention belongs to the field of ultra-thin glass technology, specifically relating to a method for controlling the small beveled edge of ultra-thin glass with a large format. Background Technology
[0002] The forming and processing of large-size ultra-thin glass has the following two limitations: 1. Large-size processing equipment has low precision. For large-format glass (≥55 inches), the forming dimensional tolerance is usually ±0.3mm. Local fine processing, such as the size of small bevels and the grinding depth, cannot be precisely controlled; 2. When the glass is thin, uneven local stress during processing increases the risk of breakage. The difficulty in controlling processing precision and the increased breakage rate result in a significant decrease in the processing yield of large-size ultra-thin glass and an increase in processing costs. Summary of the Invention
[0003] The purpose of this invention is to provide a method for controlling the small bevel of ultra-thin glass with a large format, in order to solve the technical problem that the size and grinding depth of the small bevel cannot be controlled. This method can control the grinding size and depth of the small bevel of ultra-thin glass with a large format, and at the same time, it can reduce the breakage rate of the product to a certain extent, thereby improving the product yield.
[0004] To address the aforementioned technical problems, this invention provides a method for controlling the small beveled edge of ultra-thin glass with a large format, comprising:
[0005] Step 1: Cleaning. Place the ultra-thin glass of a large format into the cleaning machine for cleaning.
[0006] Step 2: Conveying. The top and bottom sides of the ultra-large format ultra-thin glass are conveyed by a conveying device, and conveying mechanisms are also set on the left and right sides of the ultra-large format ultra-thin glass.
[0007] Step 3: Polishing. The left and right sides of the ultra-thin glass with a large format are stably conveyed and polished through the grinding wheel set.
[0008] The conveying device includes a first conveyor belt, positioning posts, and a differential speed gauge. The positioning posts and the differential speed gauge are both located inside the first conveyor belt. A first pressure sensor is installed on the positioning posts. The first pressure sensor is used to sense the pressure between the first conveyor belt and the ultra-thin glass with an ultra-large surface area. The first pressure sensor is electrically connected to a first servo motor. The first servo motor controls the distance between the first conveyor belt and the ultra-thin glass with an ultra-large surface area to adjust and control the pressure of the first conveyor belt on the ultra-thin glass with an ultra-large surface area.
[0009] The conveying mechanism includes a second conveyor belt located on the left and right sides of the ultra-thin glass with an ultra-large surface area. The structure of the second conveyor belt is the same as that of the conveying devices on the upper and lower surfaces. It also has positioning posts and pressure sensors and servo motors installed on the positioning posts.
[0010] Furthermore, two second conveyor belts are provided on both sides of the ultra-thin glass with a large surface area, and the grinding wheel set is arranged between the two second conveyor belts to stabilize the position of the ultra-thin glass with a large surface area through the second conveyor belts, and to grind the ultra-thin glass with a small bevel through the grinding wheel set.
[0011] The grinding wheel assembly includes a first grinding wheel and a second grinding wheel;
[0012] The first grinding wheel is a coarse grinding wheel with a mesh size of 500 and a rotation speed of 3000 rpm.
[0013] The second grinding wheel is a fine grinding wheel, and the mesh size of the second grinding wheel is 1000 mesh as the first grinding wheel, with a rotation speed of 4000 rpm.
[0014] Furthermore, a second pressure sensor is provided on the grinding wheel assembly, and the second pressure sensor is electrically connected to a second servo motor. The second servo motor controls the distance between the grinding wheel assembly and the ultra-thin glass with an ultra-large surface area, so as to adjust and control the grinding pressure of the grinding wheel assembly on the ultra-thin glass with an ultra-large surface area, thereby controlling the grinding depth of the small bevel.
[0015] Furthermore, the conveying speed of the first and second conveyor belts is 1.5-2.5 meters per minute.
[0016] The beneficial effects of this invention are:
[0017] 1. By applying pressure to ultra-thin glass of ultra-large format, a stable transmission is formed, thereby improving the stability of polishing ultra-thin glass of ultra-large format and being able to control the size and depth of polishing the small bevels on ultra-thin glass of ultra-large format.
[0018] 2. By setting conveyor belts on the upper and lower surfaces and left and right sides of the ultra-thin glass with a large format, the ultra-thin glass with a large format can be fixed around all sides, improving the stability of conveying and polishing.
[0019] 3. The differential speed sensor can measure the conveying speed of the upper and lower conveyor belts, thereby adjusting the conveying speed of the conveyor belts to make the upper and lower conveyor belts move at the same speed, resulting in more stable glass conveying.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] Example:

[0033] The conveying device 1 includes a first conveyor belt 11, a positioning post 12, and a differential speed gauge 15. The positioning post 12 and the differential speed gauge 15 are both located inside the first conveyor belt 11. A first pressure sensor 13 is installed on the positioning post 12. The first pressure sensor 13 is used to sense the pressure between the first conveyor belt 11 and the ultra-thin glass with an ultra-large surface area. The first pressure sensor 13 is electrically connected to a first servo motor 14. The first servo motor 14 controls the distance between the first conveyor belt 11 and the ultra-thin glass with an ultra-large surface area, so as to adjust and control the pressure of the first conveyor belt 11 on the ultra-thin glass with an ultra-large surface area.
[0034] The conveying mechanism 2 includes a second conveyor belt 21 located on the left and right sides of the ultra-thin glass with an ultra-large surface area. The structure of the second conveyor belt 21 is the same as that of the conveying device 1 on the upper and lower surfaces. It also has positioning posts and pressure sensors and servo motors installed on the positioning posts.
[0035] Two second conveyor belts 21 are provided on both sides of the ultra-thin glass with a large surface area, and the grinding wheel group 3 is set between the two second conveyor belts 21 to stabilize the position of the ultra-thin glass with a large surface area, and to grind the ultra-thin glass with a small bevel by the grinding wheel group 3.
[0036] like Figure 2 and Figure 3 As shown, the grinding wheel assembly 3 includes a first grinding wheel 31 and a second grinding wheel 32; the first grinding wheel 31 is a coarse grinding wheel with a mesh size of 500 and a rotation speed of 3000 rpm; the second grinding wheel 32 is a fine grinding wheel with a mesh size of 1000 times that of the first grinding wheel 31 and a rotation speed of 4000 rpm.
[0037] The grinding wheel assembly 3 is equipped with a second pressure sensor 32, which is electrically connected to a second servo motor 33. The second servo motor 33 controls the distance between the grinding wheel assembly 3 and the ultra-thin glass with a large surface area, so as to adjust and control the grinding pressure of the grinding wheel assembly 3 on the ultra-thin glass with a large surface area, thereby controlling the grinding depth of the small bevel.
[0038] In this embodiment, the conveying speed of the first conveyor belt 11 and the second conveyor belt 21 is 1.5-2.5 meters per minute.
[0039] In summary: By applying pressure to ultra-thin glass of an ultra-large format, a stable conveying system is formed, thereby improving the stability of polishing ultra-thin glass of an ultra-large format and enabling control over the size and depth of polishing the small bevels on the ultra-thin glass. By setting conveyor belts on the upper and lower surfaces and left and right sides of the ultra-thin glass of an ultra-large format, the glass can be fixed around all sides, improving both conveying stability and polishing stability. The differential speed gauge 15 can measure the conveying speed of the upper and lower conveyor belts, allowing for adjustments to ensure that the conveying speeds of the upper and lower conveyor belts are consistent, resulting in more stable glass conveying.
