Description

Technical Field

[0001] The invention belongs to the technical field of down-drawing electronic glass production and forming equipment, and relates to a driving short roller mechanism for producing electronic glass and a precision adjustment method thereof. Background Art

[0002] The accuracy of the equipment is crucial for the overflow down-draw method to produce substrate / cover glass. First, high-precision equipment can ensure that the molten glass maintains a stable thickness and uniform flow rate during the flow process, thereby avoiding uneven thickness or surface defects during the cooling process. Secondly, the high-precision short roller mechanism can accurately control the stretching and cooling process of the glass, which is crucial to obtaining the ideal glass performance and appearance. If the equipment accuracy is not up to standard, it may cause defects such as uneven glass thickness, ripples or scratches on the surface, and in severe cases, even lead to unqualified products or the process cannot proceed normally.

[0003] In the overflow down-draw production, there are many factors that affect the accuracy of the short roller mechanism. First, the processing accuracy and assembly accuracy of the equipment parts are the key factors affecting the overall accuracy. If the processing accuracy of the parts is insufficient or there are errors in the assembly process, the overall accuracy of the equipment will decrease. Secondly, the vibration and wear of the equipment during operation will also affect the accuracy. After long-term operation, the accuracy of the parts of the equipment may be reduced due to wear or fatigue. In addition, environmental factors such as temperature and humidity may also have a certain impact on the accuracy of the equipment.

[0004] Therefore, in the process of producing substrate / cover glass by overflow down-draw method, the short roller mechanism is one of the core equipment, and its importance is self-evident. This production method can produce high-quality glass products with uniform thickness and smooth surface by precisely controlling the flow and cooling process of molten glass. However, when the glass thickness reaches the thinnest 0.4mm, the precision requirements for the short roller mechanism reach an unprecedented level. The accuracy of the equipment directly affects the process production. If the equipment accuracy is unqualified, it may lead to unqualified products or even the process cannot be produced normally. Therefore, there is an urgent need for a precision adjustment method to solve the difficulties existing in the existing technology. Summary of the invention

S2-3 Tighten all the fixing screws of the integral support. At this point, the installation and precision adjustment of the integral support are completed. Figure 3 In order to ensure that the driving short roller mechanism can be accurately installed in the predetermined position of the annealing furnace and keep it consistent with the center line of the furnace body, the glass quality problems caused by position deviation during the production process can be avoided.

If not, make the component level by adding gaskets of different thicknesses to the mounting surfaces of the guide beam and the mounting seat. At this point, the installation and precision adjustment of component (C) are completed. The linear guide and guide beam are the guiding and supporting components in the driving short roller mechanism, and their horizontal accuracy directly affects the operating accuracy and stability of the mechanism. It is of great significance to improve the production quality and efficiency of electronic glass.
