Description

Technical Field

[0001] This application belongs to the field of glass technology, and in particular relates to a glass strengthening visualization analysis device. Background Technology

[0002] In the glass processing industry, the strength of glass needs to be improved through three stages: preheating, chemical strengthening, and annealing. The process of improving strength usually involves placing the raw glass sheet in a glass sample basket and then placing it in the quartz bath of a strengthening furnace for preheating, chemical strengthening, and annealing. Preheating and annealing are heat treatments, while the chemical strengthening stage requires a potassium nitrate salt bath in the strengthening furnace, which contains molten potassium nitrate at the high temperature required for strengthening. By replacing the sodium and lithium ions with smaller ionic radii in the glass with the potassium ions with larger ionic radii in the potassium nitrate salt bath, the strength of the glass is improved.

[0003] However, for glass, especially ultra-thin glass, the warpage of the raw glass sheet is almost "zero" before the preheating process of chemical strengthening. However, during the three stages of preheating, chemical strengthening, and annealing, the preheating process may cause uneven heating of the glass, which can easily generate thermal stress and lead to warping. In addition, during the ion exchange process in the chemical strengthening stage, the glass is immersed in molten salt, and the inconsistent ion exchange rate in different parts can also cause deformation. At the same time, if the cooling is too fast or uneven during the annealing step, residual stress may also occur, leading to warping. Therefore, ultra-thin glass that has undergone the three stages of preheating, chemical strengthening, and annealing is prone to significant tempering warpage. To improve this situation, the process parameters of the three stages of preheating, chemical strengthening, and annealing need to be optimized. However, under current conditions, it is not possible to intuitively determine which link or process parameter in the three stages of preheating, chemical strengthening, and annealing is prone to glass warping.

[0004] This invention provides a glass strengthening visualization analysis device that records photos of the three stages of preheating, chemical strengthening, and annealing in real time. It can analyze the stages and process parameters that are prone to glass warping, thereby optimizing the glass strengthening process. Utility Model Content

Detailed Implementation

[0048] This application provides a glass strengthening visualization analysis device to solve the technical problem of the lack of glass strengthening visualization devices in the prior art.

[0049] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] Example 1

[0051] Given that glass warping cannot be visually observed during the preheating, chemical strengthening, and annealing stages, and that analyzing the glass warping caused by the process parameters of preheating, chemical strengthening, and annealing is difficult, there is currently a lack of glass strengthening visualization equipment. Embodiment 1 of this application provides a glass strengthening visualization analysis device, the front and side views of which are shown below. Figure 1-2 As shown.

[0052] The glass strengthening visualization analysis device provided in Embodiment 1 of this application includes components such as a glass sample basket, a quartz tank, a resistance heating device, a cover plate, and a panoramic camera. The glass sample basket is placed in the cavity of the quartz tank, the resistance heating device is installed on the inner wall of the quartz tank, the cover plate covers the top of the quartz tank, a high borosilicate glass observation window is installed in the tank body, and a panoramic camera is installed on the side of the high borosilicate glass observation window away from the quartz tank. With the tank body as the boundary, one side is the direction of the quartz tank cavity, and the other side is the direction of the outer side of the quartz tank. In this embodiment, the "side away from the quartz tank" is the direction of the outer side of the quartz tank.

[0053] In this embodiment, a glass strengthening visualization analysis device is provided. Because a high borosilicate glass observation window is installed in the quartz tank, similar to a window on a wall, and because high borosilicate glass has advantages such as high transparency, high heat resistance, low coefficient of thermal expansion, and corrosion resistance, it maintains stable properties during preheating, chemical strengthening, and annealing. Therefore, during these processes, a panoramic camera can clearly observe the sample through the glass observation window, capturing the sample's shape throughout the process and recording its changes. This enables real-time monitoring and analysis of glass warping, overcoming the current lack of glass strengthening visualization equipment.

[0054] Example 2

With the quartz tank body as the boundary, one side is the direction of the quartz tank cavity, and the other side is the direction of the outer side of the quartz tank. In this embodiment, the "side away from the quartz tank" is the direction of the outer side of the quartz tank.

[0057] This embodiment provides a glass strengthening visualization analysis device that can capture the shape of the sample throughout the entire process and record the changes in the sample. In addition, it has a high borosilicate glass illumination window on the cover plate and an illumination lamp on the side of the high borosilicate glass illumination window away from the quartz tank. The illumination lamp provides brightness to the quartz tank, avoiding the defect that the light from the heating unit when the temperature inside the strengthening furnace is around 400°C is insufficient to meet the brightness required by the camera.

[0058] Example 3

[0059] Embodiment 3 of this application provides a glass strengthening visualization analysis device, the front and side schematic diagrams of which are shown below. Figure 1-2 As shown.

[0060] The glass strengthening visualization analysis device provided in Embodiment 3 of this application includes components such as a glass sample basket, a quartz tank, a resistance heating device, a cover plate including a high borosilicate glass illumination window, an LED light, a panoramic camera, a motor, and a linear guide rail.

The LED light is installed on the side of the high borosilicate glass illumination window away from the quartz tank.

[0061] This embodiment provides a glass strengthening visualization analysis device that, in addition to capturing the shape of the sample throughout the process, recording the sample's changes, and providing a light source for the strengthening furnace, also features a motor and linear guide rail components. By fixing the camera on the slider of the linear guide rail, the camera can move left and right or up and down with the movement of the slider when the motor drives the linear guide rail, achieving more comprehensive observation and monitoring.

[0062] Example 4

[0063] Embodiment 4 of this application provides a glass strengthening visualization analysis device, the front and side schematic diagrams of which are shown below. Figure 1-2 As shown.

[0064] The glass strengthening visualization analysis device provided in Embodiment 4 of this application includes components such as a glass sample basket, a quartz tank, a resistance heating device, a cover plate including a high borosilicate glass illumination window, an LED light, a panoramic camera, a motor, and a linear guide rail.

[0065] This embodiment provides a glass strengthening visualization analysis device that can capture the shape of the sample throughout the process, record the changes in the sample, provide a light source inside the strengthening furnace, and drive the camera to move for more comprehensive observation and monitoring. In addition, because heating devices are set on the bottom, sides, and front, the glass can be heated more evenly during the preheating, chemical strengthening, and annealing stages, reducing the occurrence of glass warping.

[0066] Example 5

[0067] Embodiment 5 of this application provides a glass strengthening visualization analysis device, the front and side schematic diagrams of which are shown below. Figure 1-2 As shown.

[0068] The glass strengthening visualization analysis device provided in Embodiment 5 of this application includes components such as a glass sample basket, a quartz tank, a resistance heating device, a cover plate including a high borosilicate glass illumination window, an LED light, a panoramic camera, a motor, and a linear guide rail. The glass sample basket is placed in the cavity of the quartz tank. The resistance heating device is installed on the inner wall of the quartz tank. The cover plate covers the top of the quartz tank. A high borosilicate glass observation window is installed in the quartz tank. A panoramic camera is installed on the side of the high borosilicate glass observation window away from the quartz tank. The quartz tank serves as a boundary, with one side representing the direction of the quartz tank cavity and the other side representing the outer direction of the quartz tank. In this embodiment, the "side away from the quartz tank" refers to the outer direction of the quartz tank. The LED light is installed on the side of the high borosilicate glass illumination window away from the quartz tank. The resistance heating device includes a bottom resistance heating device, a side resistance heating device, and a front resistance heating device. The bottom resistance heating device is located at the bottom of the inner wall of the quartz tank. The quartz tank has a side resistance heating device installed on the inner wall side and a front resistance heating device installed on the inner wall front. The quartz tank body is equipped with borosilicate glass observation windows, including an observation window at the bottom of the tank body, an observation window on a first side of the tank body, and an observation window on a second side of the tank body, with the first and second sides being opposite sides. Correspondingly, a bottom camera is installed on the side of the bottom borosilicate glass observation window away from the quartz tank, a first side camera is installed on the side of the first side borosilicate glass observation window away from the quartz tank, and a second side camera is installed on the side of the second side borosilicate glass observation window away from the quartz tank.

[0069] This embodiment provides a glass strengthening visualization analysis device that, in addition to capturing the shape of the sample throughout the entire process, recording the sample's changes, providing a light source inside the strengthening furnace, and driving the camera to move for more comprehensive observation and monitoring and even heating of the glass, also enables more precise and comprehensive observation and monitoring of the glass during the preheating, chemical strengthening, and annealing stages through the bottom observation window and the oppositely set first and second side observation windows.

[0070] Experimental Example 1

[0071] Experimental Example 1 of this application uses the glass strengthening visualization analysis equipment provided in Example 5 to preheat, chemically strengthen, and anneal the glass. The preheating, chemical strengthening, and annealing processes are time-consuming and at high temperatures, which may damage the camera. Therefore, this experimental example also provides a protective gas inlet and a protective gas outlet on the equipment housing of the glass strengthening visualization analysis equipment. In addition, to stabilize the motor and improve stability, the bottom motor, the first side motor, and the second side motor are fixed to the equipment housing.

[0072] In Example 1 of this experiment, during the preheating and annealing stages: the glass sample is inserted into the glass sample basket. The first side support, the second side support, and the bottom support of the glass sample basket can stabilize the glass sample. Then, it is placed into the cavity of the quartz tank. At this time, there is no nitrate required for chemical strengthening in the quartz tank cavity. The cover plate is then closed. Since the temperature inside the furnace is around 400℃ during strengthening, the resistance heating device is difficult to reach the required brightness. Therefore, a light source is provided to the quartz tank cavity through an illumination lamp. Then, the preheating / cooling annealing is started according to the set temperature curve, and the changes of the glass sample during the chemical strengthening process are observed.

[0073] In the chemical strengthening stage of Example 1 of this experiment: after the sample was preheated, molten nitrate required for chemical strengthening was added into the cavity of the quartz tank, and the changes of the glass sample during the chemical strengthening process were observed.

[0074] Videos or photographs from three cameras were collected to record the time when the glass sample deformed during the strengthening process. The depth of the stress layer in the glass was analyzed accordingly, and appropriate measures were taken to mitigate the deformation. These measures included adjusting the strengthening heating curve, the strengthening annealing curve, and the support points of the strengthening basket, thereby improving the strengthening warpage. In Example 1 of this experiment, the glass sample was inserted into a glass sample basket. The bottom and side views of the glass sample basket after placement are shown in the diagram. Figure 3-4 As shown, the temperature and time parameters for the preheating, chemical strengthening, and annealing stages are as follows: Figure 5 As shown, from Figure 3 It can be seen that the original glass sheet (glass sample) has no warping, but after preheating, chemical strengthening and annealing, it becomes warped.

[0075] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
