Description

Technical Field

[0001] The invention belongs to the technical field of substrate glass production and relates to a heating equipment replacement device and method. Background Art

[0002] Liquid crystal flat panel displays (LCDs), key products in the modern electronic information display field, are widely used in consumer electronics, industrial control, medical imaging, and other fields due to their advantages such as high resolution, low power consumption, and lightweight portability. Liquid crystal substrate glass, as the core material of LCD flat panel displays, is an indispensable component of flat panel display devices. Market demand for LCD substrate glass continues to grow with the continuous advancement of display technology, showing extremely broad development prospects.

[0003] Liquid crystal substrate glass plays a key role in flat-panel display devices, supporting the liquid crystal layer and providing an optical path. Its performance plays a decisive role in the display's visual quality and reliability. This material possesses a series of excellent properties: First, it has high thermal conductivity. During the operation of an LCD, components such as the backlight module generate heat. The high thermal conductivity of the substrate glass quickly transfers this heat to the cooling system, preventing localized overheating that can disrupt the alignment of liquid crystal molecules and cause pixel failure, thereby ensuring stable operation and a long lifespan. Second, the LCD substrate glass exhibits extremely high flatness and smoothness. In LCD technology, pixel sizes are typically in the micron range. Minute fluctuations in the substrate glass surface can affect the orientation and distribution of liquid crystal molecules, leading to color aberration and uneven brightness in the displayed image. Therefore, high flatness and smoothness are key factors in ensuring the high resolution and contrast of LCDs. Furthermore, LCD substrate glass exhibits excellent optical properties, including high transparency and a wide viewing angle. High transparency ensures minimal light loss when passing through the glass, improving the brightness and color saturation of the display; the wide viewing angle allows users to obtain clear and accurate image display at different viewing angles.

[0004] In the production of liquid crystal glass substrates, heating equipment is a key factor affecting product quality and production stability. By precisely controlling the temperature field, heating equipment provides the necessary thermal environment for glass melting, forming, and annealing processes. However, as equipment operates, its performance gradually degrades due to factors such as aging of the heating elements and reduced temperature control system accuracy. It can also experience sudden failures, such as heating element damage or circuit shorts. This degradation or failure of the heating equipment can lead to uneven temperature distribution at the edges of the glass sheet, causing thermal stress variations, edge deformation, and increased thickness variation. These issues can severely impact the dimensional accuracy, surface quality, and optical properties of the liquid crystal glass substrates, making them unable to meet the production requirements of liquid crystal displays. Therefore, when heating equipment fails to meet production and process requirements, it must be replaced promptly. However, current replacement methods are risky due to space constraints, and errors in accuracy during replacement can inevitably damage the equipment itself. Summary of the Invention
