Description

Technical Field

[0001] The utility model belongs to the technical field of liquid crystal glass substrate production, and relates to a traction roller monitor fixing device for liquid crystal glass substrate production. Background Art

[0002] In the modern liquid crystal display panel manufacturing industry, the production of liquid crystal glass substrates is a key technical link, and its quality directly impacts the performance and quality of the final display product. As one of the mainstream processes for producing high-quality liquid crystal glass substrates, the overflow down-draw method is widely used in the manufacture of high-end display products due to its ability to produce large-scale, highly flat glass substrates with low defect density. This method achieves continuous production of high-quality glass substrates by precisely controlling the flow and cooling of molten glass. In this process, the pulling roller, a key piece of equipment, is responsible for clamping and pulling the glass sheet downward. The stability and precision of its operation directly impact the quality of the finished glass substrate.

[0003] However, when traction rollers operate continuously for extended periods of time, they inevitably experience frictional wear from contact with the hot, hard, and smooth glass sheets. This wear not only gradually erodes the roller's head covering, resulting in an uneven surface, but also significantly increases the roller's runout. This runout not only reduces the smoothness of glass sheet transport and increases the risk of surface scratches and deformation, but can also, in more serious cases, directly cause glass sheets to break during high-speed movement, severely impacting production line stability and product yield.

[0004] To address this issue, the industry has developed a variety of pull-roller runout monitors. These monitor real-time roll runout, promptly detecting and warning of potential failures, thereby avoiding or reducing production accidents caused by roll runout. However, the effectiveness and accuracy of these monitors depend heavily on the stability and positioning accuracy of their installation. Traditional installation methods often suffer from issues such as loose fixings and complex installation, making it difficult to ensure the stability and accuracy of the monitors in harsh production environments, thus compromising the reliability of the monitoring data. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problems in the prior art that the traction roller monitor is not firmly fixed, the installation is complicated, it is difficult to ensure the stability and accuracy of the monitor in harsh production environments, and the reliability of the monitoring data is affected. A traction roller monitor fixing device for liquid crystal glass substrate production is provided.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A fixing device for a traction roller monitor for producing liquid crystal glass substrates, comprising a fixing support rod and a mounting seat;

[0008] The fixed support rod includes a fixed flange and a fixed rod; the fixed flange is connected to the fixed rod;

[0009] The mounting seat includes a mounting base and a mounting plate; the mounting plate is arranged perpendicular to the mounting base; and the mounting base is fixedly connected to the fixing rod.

[0010] Furthermore, a plurality of mounting holes are provided on the fixing flange.

[0011] Furthermore, the fixing rod is a rectangular parallelepiped structure with a hollow inner cavity.

[0012] Furthermore, the bottom of the mounting base is flat, and extension portions are provided on both sides extending upward.

[0013] Furthermore, the fixing device for the traction roller monitor for producing liquid crystal glass substrates further includes a protective cover connected to an extension of the mounting base.

[0014] Furthermore, a wire outlet hole is provided on the protective cover.

[0015] Furthermore, the wire outlet hole is arranged at the middle position of the bottom of the protective cover.

[0016] Furthermore, an opening is provided on the top of the protective cover to ensure the transmission of the laser beam emitted by the monitor.

[0017] Furthermore, a cooling air installation pipe is provided on the protective cover.

[0018] Furthermore, the cooling air installation pipe is arranged at the center position of the side surface of the protective cover.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The utility model discloses a fixing device for a traction roller monitor for the production of liquid crystal glass substrates, which adopts a combined design of a fixed support rod and a mounting base, wherein the fixed support rod is composed of a fixed flange and a fixed rod, which ensures the stability and load-bearing capacity of the overall structure. This stable support structure provides a solid installation foundation for the traction roller monitor, effectively reducing the monitoring error caused by vibration or external force, thereby improving the monitoring accuracy and ensuring quality control during the production of liquid crystal glass substrates. The design of the mounting base fully considers the convenience of on-site installation and maintenance. The fixed connection between the mounting base and the fixed rod is simple and quick, and the mounting plate is vertically arranged on the mounting base, which facilitates the rapid installation and adjustment of the traction roller monitor, so that when the monitor needs to be maintained or replaced, it can be quickly disassembled and reassembled, thereby improving production efficiency.

[0021] Furthermore, multiple mounting holes are provided on the fixed flange. The design of multiple mounting holes enables the fixed flange to flexibly select the installation position and angle according to the specific installation environment and requirements. This flexibility not only facilitates finding a suitable installation point in a complex production line environment, but also ensures that the traction roller monitor is fixed in the optimal posture, further improving the monitoring accuracy.

[0022] Furthermore, by providing a wire outlet hole on the protective cover, the overall safety of the device is improved, so that the cables of the monitor can be led out in an orderly and safe manner, avoiding the disorderly arrangement of cables outside the device, and reducing the safety risks caused by accidents such as tripping and pulling of cables. The wire outlet hole is located in the middle of the bottom of the protective cover. Such a layout is convenient for leading out the cables and can minimize the interference of the cables on the monitor, ensuring the stable operation of the monitor in a closed and protected environment, and improving the accuracy and reliability of the monitoring data. The provision of the wire outlet hole makes it possible to quickly and easily disconnect the cables and open the protective cover for operation when the monitor needs to be maintained or replaced, without having to disassemble or move the entire device, which greatly improves maintenance efficiency.

[0023] Furthermore, an opening in the top of the protective cover allows the laser beam emitted by the monitor to penetrate the protective cover directly and unobstructed, illuminating the traction roller under test. This unimpeded transmission method ensures that the intensity and directionality of the laser beam are not affected, thereby ensuring the accuracy and reliability of the monitoring data and providing a strong guarantee for the production quality of liquid crystal glass substrates.

[0024] Furthermore, a cooling air duct installed on the protective cover allows external cooling air to be directly delivered into the protective cover, effectively dissipating heat and cooling the monitor. During the LCD glass substrate production process, high temperatures can damage the monitor's internal electronic components, affecting their stability and lifespan. By dissipating heat promptly, the monitor can operate at an appropriate temperature, protecting it from high-temperature damage. BRIEF DESCRIPTION OF THE DRAWINGS
