Description
Technical Field
[0001] The present invention relates to the technical field of substrate glass testing, and in particular to a device and method for off-line determination of substrate glass flow direction. Background Art
[0002] As one of the key components of display devices, substrate glass directly affects the display's performance indicators such as resolution, light transmittance and viewing angle. In the LCD / OLED process, devices such as thin-film transistors and pixel electrodes need to be formed directly on the substrate glass through a photolithography process with multiple heating. In order to ensure the geometric stability of the panel and the precise alignment of the pixels, and maintain the performance of transistors and electrodes, the thermal stability requirements of the substrate glass are more stringent, and thermal shrinkage is an important parameter to measure the thermal stability of glass.
[0003] In order to avoid the influence of the molding and drawing temperature difference on the results, the heat shrinkage test samples are all carried out along the direction of the production flow plate. In the daily production sampling process, it is inevitable to ignore the flow direction mark, resulting in unclear heat shrinkage sample preparation direction. The unclear sample preparation direction not only increases the error in the test process, but also reduces the test efficiency and result accuracy because of the need to repeatedly confirm and adjust the direction. It can be seen that the current technology lacks an efficient and automated flow direction determination method. Summary of the invention
[0004] The purpose of the present invention is to provide a device and method for offline determination of the flow direction of substrate glass, so as to overcome the problems existing in the prior art. The present invention can effectively determine the flow direction when the production flow plate direction of the glass sample is unclear, so as to meet the sample preparation requirements for characterizing the thermal shrinkage performance of samples with unknown flow direction. It can not only avoid misjudgment of the flow direction of samples with unknown flow direction and improve the accuracy and efficiency of flow direction determination, but also reduce the probability of misleading the thermal shrinkage test results due to unclear sample preparation direction, especially for scarce samples, and greatly improve the efficiency of thermal shrinkage performance testing.
[0005] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A device for offline determination of substrate glass flow direction, comprising a sample rack and a light projection device; the sample rack comprises a clamping frame, and multi-stage lifting rods are installed on both sides of the clamping frame, and the multi-stage lifting rods are connected to a motor; a plurality of fixing clamps are arranged on the clamping frame, and a plurality of rotating components are also installed on the clamping frame, and a support frame is installed at the bottom of the rotating component; the light projection device comprises a strong light emitting device, and a light source lifting mechanism is installed at the bottom of the strong light emitting device; Furthermore, a light source rotating assembly is installed at the bottom of the strong light emitting device; Furthermore, the light source lifting mechanism is installed at the bottom of the light source rotating assembly; Furthermore, the number of the rotating components is 2; Furthermore, the two rotating components are respectively mounted on the upper end and the lower end of the clamping frame; Furthermore, the two rotating components are respectively installed along the central axis of the clamping frame; Furthermore, the support frame is installed at the bottom of the lower end rotating assembly.
[0006] A method for offline determination of substrate glass flow direction, based on the above-mentioned device for offline determination of substrate glass flow direction, comprises the following steps: (1) The substrate glass sample to be judged is suspended on a clamping frame in a dark room through a fixing clamp. After the substrate glass sample is stably suspended, the multi-stage lifting rod is retracted; (2) Adjust the light source lifting mechanism so that the strong light emitting device is located in the middle of the edge of the substrate glass sample, turn on the strong light emitting device, and project light from the end face of the edge of the substrate glass sample; (3) Rotate the clamping frame or the strong light emitting device. If light and dark vertical textures appear on the projection of the substrate glass sample, the texture direction is the flow plate direction when the substrate glass sample is produced; If no light and dark vertical textures appear on the projection of the substrate glass sample, the multi-stage lifting rod is extended, the substrate glass sample is removed, and the substrate glass sample is rotated 90° along the edge direction of the substrate glass sample, and (1) is performed again; Furthermore, the direction of the projected light in (2) is perpendicular to the direction in which the substrate glass sample is suspended; Furthermore, the clamping frame or the strong light emitting device in (3) rotates at a speed of 1° / s.
[0007] The above technical solution has the following advantages or beneficial effects: The present invention provides an off-line device and method for determining the flow direction of substrate glass. Multi-stage lifting rods are installed on both sides of a clamping frame and fixed at the wide part of a substrate glass sample. The multi-stage lifting rods are connected to a motor and driven by a DC circuit to realize linear motion. After the substrate glass is clamped stably, the multi-stage lifting rods can automatically extend and retract without affecting the projection of the light path from the wide side of the substrate glass sample, thereby preventing the wide side of the clamping frame from leaving a projection shadow to interfere with the result judgment. Substrate glass samples of different sizes and shapes can be firmly clamped by a plurality of fixing clamps on the clamping frame, thereby improving the versatility and flexibility of the device and enabling the device to be applicable to substrate glass samples of various specifications. A rotating assembly is provided so that the substrate glass sample can be rotated and adjusted during the detection process to ensure that light can be irradiated onto the substrate glass sample from different angles, thereby more comprehensively detecting its flow direction characteristics. The projection device is used as the light source. Through the precise control of the light source lifting mechanism, it can ensure that the light is irradiated onto the substrate glass sample at a stable and adjustable angle and intensity, making the detection process more accurate and reliable, and can effectively capture the subtle flow characteristics on the projection of the substrate glass sample; the device adopts an offline judgment method, that is, the substrate glass sample is detected without interrupting the production line, which not only improves the detection efficiency, but also avoids the interference and errors that may be caused by online detection, ensuring the accuracy of the detection result; the entire device structure of the present invention is reasonably designed, and the various components work together to achieve rapid clamping, rotation and detection of the substrate glass sample. Through an efficient workflow, the detection speed is significantly improved and the labor cost is reduced; through an integrated automatic control system, the operator only needs to simply set the parameters, and the device can automatically complete the detection task, reducing human intervention and improving work efficiency and detection accuracy.
[0008] Furthermore, by setting up a light source rotating assembly, the strong light emitting device can rotate around its axis, and the light source can illuminate the substrate glass sample from multiple angles, thereby realizing all-round detection of the flow characteristics on the projection of the substrate glass sample. Multi-angle illumination helps to capture more comprehensive information and improve the accuracy and reliability of detection. At the same time, there is a risk of breakage of the substrate glass sample when it rotates on the rotating assembly. By setting up a light source rotating assembly, the risk of sample breakage during the detection process can be avoided, thereby realizing protection of the sample to be tested.
[0009] Furthermore, two rotating assemblies are respectively installed at the upper and lower ends of the clamping frame and installed along the central axis of the clamping frame. This symmetrical layout helps to maintain the stability of the substrate glass sample during the detection process; the support frame is installed at the bottom of the lower end rotating assembly, providing a stable support for the entire substrate glass sample, enhancing the stability and load-bearing capacity of the device, so that it can maintain good performance even under high-intensity or long-term working conditions.
[0010] Furthermore, by installing two rotating components respectively along the central axis of the clamping frame, the entire device can achieve 360° rotation around the central axis, which greatly enhances the flexibility of the device and allows the operator to conveniently adjust the orientation of the projection of the substrate glass sample by rotating the clamping frame without moving the substrate glass sample itself, thereby more accurately determining its flow direction.
[0011] The present invention also provides a method for determining the flow direction of substrate glass off-line, which can effectively determine the flow direction of substrate glass samples; in the glass production process, due to the influence of multiple factors such as melt, laminar flow, and drawing molding, an allowable thickness difference will be formed, and under optical irradiation, light and dark stripes will appear on the projection of the substrate glass within a certain angle. In a darkroom environment, through the irradiation of strong light perpendicular to the sample hanging direction, and the slow rotation of the substrate glass sample, the length of the light wave path changes under a slight angle change, and the light and dark texture state can be reflected on the projection of the substrate glass sample. According to the texture direction, the flow direction of the substrate glass sample can be determined; the substrate The glass sample is suspended on the clamping frame by a fixing clamp, which not only ensures the stability of the substrate glass sample during the detection process and prevents it from shaking or falling off during the rotation process, but also simplifies the installation and removal process of the substrate glass sample and improves the detection efficiency; after the substrate glass sample is stably suspended, the multi-stage lifting rod is retracted, which does not affect the projection of the light path from the wide side of the substrate glass sample, further reduces the projection shadow left by the wide side of the clamping frame, prevents interference with the judgment, and improves the accuracy of the judgment result; by adjusting the light source lifting mechanism, the strong light emitting device can be accurately located in the middle of the edge of the substrate glass sample, thereby ensuring The light is evenly projected from the end face of the edge of the substrate glass sample, which helps to more clearly display the flow direction characteristics on the projection of the substrate glass sample; the design of the rotating component enables it to accurately rotate the substrate glass sample at a preset speed, thereby allowing the operator to clearly observe the light and dark vertical textures on the projection of the substrate glass sample, and then accurately determine the flow direction; if the light and dark vertical textures do not appear on the projection of the substrate glass sample in the initial detection, the substrate glass sample is removed and rotated 90° along the edge direction, and then the detection steps are re-executed, ensuring the flexibility of the adjustment method; the method of the present invention can be applied to substrate glass samples of different sizes, shapes and materials The product has strong adaptability and versatility; the method adopts an off-line detection mode and can be carried out without interrupting the production line, which helps to reduce interference and downtime to the production line, thereby reducing production costs; the present invention can effectively determine the flow direction when the production flow plate direction of the substrate glass sample is unclear, so as to meet the sample preparation requirements for characterizing the thermal shrinkage performance of samples with unknown flow directions, which can not only avoid misjudgment of the flow direction of samples with unknown flow directions and improve the accuracy and efficiency of flow direction determination, but also reduce the probability of misleading the thermal shrinkage test results due to unclear sample preparation directions, especially for scarce samples, and greatly improve the efficiency of thermal shrinkage performance testing.
[0012] Furthermore, when the direction of light projection is perpendicular to the direction in which the substrate glass sample is suspended, the light can penetrate the edge of the substrate glass sample in the most direct way, thereby forming a vertical texture with obvious light and dark contrast on the projection of the substrate glass sample, thereby enabling the operator to accurately judge the flow direction; vertical light projection reduces the scattering and reflection of light on the surface and edge of the substrate glass sample, reduces background noise and interference factors, and makes the light and dark vertical textures on the projection of the substrate glass sample more prominent and easy to identify, which helps to improve the accuracy and reliability of detection.
[0013] Furthermore, rotating the substrate glass sample at a speed of 1° / s not only ensures the stability of the detection process, but also enables the light and dark vertical textures to be clearly presented. By observing the texture direction, the flow plate direction during the production of the substrate glass sample can be accurately determined. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention also provides a method for offline determining the flow direction of substrate glass. Based on the above-mentioned device for offline determining the flow direction of substrate glass, the method comprises the following steps: (1) The substrate glass sample to be judged is suspended on the clamping frame 1 in the dark room through the fixing clamp 2. After the substrate glass sample is stably suspended, the multi-stage lifting rod 1-1 is retracted; (2) adjusting the light source lifting mechanism 6 so that the strong light emitting device 5 is located in the middle of the edge of the substrate glass sample, turning on the strong light emitting device 5, and projecting light from the end surface of the edge of the substrate glass sample, with the direction of the light projected being perpendicular to the direction in which the substrate glass sample is suspended; (3) The strong light emitting device 5 is rotated at a speed of 1° / s.

[0020] Embodiment 3: like Figure 1 , Figure 2 and Figure 3As shown, the present invention provides an off-line device for determining the flow direction of substrate glass, including a sample rack and a light projection device; the sample rack includes a clamping frame 1, and multi-stage lifting rods 1-1 are installed on both sides of the clamping frame 1 and fixed at the wide part of the substrate glass sample. The multi-stage lifting rods 1-1 are connected to a motor, and a DC circuit is used to drive the multi-stage lifting rods 1-1 to achieve linear motion. The core of the device is to reduce the rotational motion of the motor through the motor through gears or worm gears, and then drive a pair of lead screw nuts to convert the rotational motion of the motor into linear motion. After the substrate glass is clamped stably, the multi-stage lifting rods 1-1 can automatically extend and retract without affecting the projection of the light path from the wide side of the substrate glass sample, so as to prevent the wide side of the clamping frame 1 from leaving a projection shadow and interfering with the result judgment; a plurality of fixing clamps 2 are arranged on the clamping frame 1, which can stably clamp substrate glass samples of different sizes and shapes, thereby improving the versatility and flexibility of the device and enabling the device to be applicable to substrate glass samples of various specifications; a plurality of rotating components 3 are also installed on the clamping frame 1 , so that the substrate glass sample can be rotated and adjusted during the detection process to ensure that the light can be irradiated to the substrate glass sample from different angles, so as to more comprehensively detect its flow characteristics; a support frame 4 is installed at the bottom of the rotating component 3, and the support frame 4 can be moved up and down according to the width of the sample to meet the support and clamping of the suspension of substrate glass samples of multiple sizes; the projection device includes a strong light emitting device 5, which is used to irradiate the light and dark textures on the projection of the substrate glass sample. The strong light emitting device 5 includes a light source rotating component 7 installed at the bottom, which is used to drive the detection light source to rotate to change the irradiation angle of the strong light emitting device 5 relative to the substrate glass sample to meet the adjustment of the incident light angle of the substrate glass sample. At the same time, the substrate glass sample rotates on the rotating component 3, and there is a risk of breakage.

A variety of light source devices can be selected according to the material, thickness, color and other characteristics of the substrate glass sample to ensure that the light source can fully illuminate and highlight the flow characteristics on the projection of the substrate glass sample, thereby improving the accuracy of the judgment; at the same time, different light source devices are suitable for different working environments and judgment requirements, so that the device has strong adaptability and flexibility.
[0022] like Figure 4 As shown, the present invention also provides a method for offline determining the flow direction of substrate glass, based on the above-mentioned device for offline determining the flow direction of substrate glass, comprising the following steps: (1) The substrate glass sample to be determined is suspended on the clamping frame 1 in the darkroom through the fixing clamp 2. The substrate glass sample is suspended on the clamping frame 1 through the fixing clamp 2, which not only ensures the stability of the substrate glass sample during the detection process and prevents it from shaking or falling off during the rotation process, but also simplifies the installation and removal process of the substrate glass sample and improves the detection efficiency; after the substrate glass sample is stably suspended, the multi-stage lifting rod 1-1 is retracted, which does not affect the projection of the light path from the wide side of the substrate glass sample, further reduces the projection shadow left by the wide side of the clamping frame 1, prevents interference with the judgment, and improves the accuracy of the judgment result; (2) Adjust the light source lifting mechanism 6 so that the strong light emitting device 5 is located in the middle of the edge of the substrate glass sample, turn on the strong light emitting device 5, and project light from the end face of the edge of the substrate glass sample. The direction of the projected light is perpendicular to the direction in which the substrate glass sample is suspended. When the direction of the projected light is perpendicular to the direction in which the substrate glass sample is suspended, the light can penetrate the edge of the substrate glass sample in the most direct way, thereby forming a vertical texture with obvious light and dark contrast on the projection of the substrate glass sample, thereby enabling the operator to accurately judge the flow direction; vertical projection reduces the scattering and reflection of light on the surface and edge of the substrate glass sample, reduces background noise and interference factors, makes the light and dark vertical textures more prominent and easier to identify, and helps to improve the accuracy and reliability of detection; (3) The clamping frame 1 or the strong light emitting device 5 is rotated at a speed of 1° / s, which not only ensures the stability of the detection process, but also enables the light and dark vertical textures on the projection of the substrate glass to be clearly presented.
