Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of substrate glass testing, in particular to a device for off-line determination of the flow direction of substrate glass. Background Art
[0002] As a key component of display devices, substrate glass directly impacts performance indicators such as resolution, light transmittance, and viewing angle. In the LCD / OLED manufacturing process, thin-film transistors and pixel electrodes are formed directly on the substrate glass through a photolithography process involving multiple heating steps. To ensure the panel's geometric stability and precise pixel alignment, while maintaining the performance of transistors and electrodes, the thermal stability requirements of the substrate glass are even more stringent. Thermal shrinkage is a key parameter in measuring the thermal stability of glass.
[0003] In order to avoid the influence of the forming and drawing temperature difference on the results, the thermal shrinkage test samples are all prepared along the production flow plate direction. However, in the daily production sampling process, it is inevitable that the flow direction mark is ignored, resulting in unclear thermal 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 due to 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. Utility Model Content
[0004] The purpose of the present utility model is to provide a device for offline determination of the flow direction of substrate glass, so as to overcome the problems existing in the prior art. The present utility model 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 directions. It 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 direction, especially for scarce samples, and greatly improve the efficiency of thermal shrinkage performance testing.
[0005] In order to achieve the above-mentioned purpose, the technical solutions adopted by the present invention are as follows:
[0006] A device for offline determination of substrate glass flow direction includes a sample holder and a light projection device; the sample holder includes a clamping frame, with multi-stage lifting rods installed on both sides of the clamping frame, and the multi-stage lifting rods are connected to a motor; the clamping frame is provided with a plurality of fixing clamps, and the clamping frame is also installed with a plurality of rotating assemblies, and the bottom of the rotating assembly is installed with a support frame; the light projection device includes a strong light emitting device, and the bottom of the strong light emitting device is installed with a light source lifting mechanism;
[0007] Furthermore, a light source rotating assembly is installed at the bottom of the strong light emitting device, and a light source lifting mechanism is installed at the bottom of the light source rotating assembly;
[0008] Furthermore, the number of the rotating components is 2;
[0009] Further, one of the rotating assemblies is mounted on the upper end of the clamping frame;
[0010] Further, the other rotating assembly is mounted on the lower end of the clamping frame;
[0011] Furthermore, the support frame is installed at the bottom of the lower end rotating assembly;
[0012] Furthermore, the two rotating components are respectively installed along the central axis of the clamping frame;
[0013] Furthermore, the clamping frame can achieve 360° rotation through two rotating components;
[0014] Furthermore, a substrate glass sample is mounted on the clamping frame via a fixing clamp;
[0015] Furthermore, the strong light emitting equipment includes but is not limited to high lumen short arc xenon lamps, lasers, strong light flashlights and strong light projection equipment.
[0016] The above technical solution has the following advantages or beneficial effects:
[0017] The utility model 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 light path projected from the wide side of the substrate glass sample, thereby preventing the wide side of the clamping frame from leaving a projection shadow and interfering with the result judgment. A plurality of fixing clamps on the clamping frame can firmly clamp substrate glasses of different sizes and shapes, thereby improving the versatility and flexibility of the device and making the device 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 on the substrate glass sample from different angles, thereby more comprehensively detecting its flow direction characteristics. The device acts as a light source, and 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, and ensures the accuracy of the detection results; the entire device of the utility model has a reasonable structural design, and the various components work together to achieve rapid clamping, rotation and detection of substrate glass samples. Through an efficient workflow, the detection speed is significantly improved and the labor cost is reduced; through the 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.
[0018] 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, the substrate glass sample rotates on the rotating assembly, and there is a risk of breakage. By setting up a light source rotating assembly, the risk of breakage of the substrate glass sample during the detection process can be avoided, thereby achieving protection of the sample to be tested.
[0019] Furthermore, the 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 inspection process; the support frame is installed at the bottom of the lower end rotating assembly, providing a solid 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.
[0020] Furthermore, by installing two rotating components along the central axis of the clamping frame, the entire device can rotate 360° around the central axis, greatly enhancing the flexibility of the device and allowing the operator to conveniently adjust the orientation of the substrate glass sample by rotating the clamping frame without moving the substrate glass sample itself, thereby more accurately determining its flow direction.
[0021] Furthermore, the substrate glass sample is suspended on the sample holder 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 rotation, but also simplifies the sample installation and removal process and improves the detection efficiency.
[0022] Furthermore, a variety of light source devices can be selected according to the material, thickness, color and other characteristics of the substrate glass sample, ensuring 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, making the device highly adaptable and flexible.
