Description

Technical Field

[0001] The invention belongs to the technical field of quartz tube processing, and in particular relates to a quartz tube bending device and method. Background Art

[0002] Quartz tubes are widely used in many fields due to their excellent physical and chemical properties, such as high purity, good light transmittance, high temperature resistance, corrosion resistance, and stable chemical properties. In the field of semiconductor manufacturing, quartz tubes are important components that support and protect wafers in high-temperature process environments for key processes such as diffusion and oxidation. In the lighting industry, quartz tubes are used to manufacture various types of lamps, such as halogen lamps and xenon lamps. Their high light transmittance and high temperature resistance ensure the efficient lighting and long life of the lamps. In the manufacture of optical instruments, quartz tubes are used to make support and protective structures for precision optical components such as optical prisms and lenses due to their low light loss and good optical uniformity. With the continuous development and technological advancement of these industries, the shape and size of quartz tubes have become more diverse and refined. Many application scenarios require quartz tubes with specific curved shapes to meet the needs of specific optical paths, spatial layouts, or process flows.

[0003] At present, most of the common quartz tube bending devices on the market use a single driving mechanism to drive the quartz tube for tube bending operations. In the actual production process, when the quartz tube on the driving mechanism is bent, it is necessary to stop the operation of the entire device first, remove the quartz tube that has completed the bending from the driving mechanism, and then reinstall the quartz tube to be bent. Only then can the device be started again for the next round of tube bending operations, resulting in a long downtime of the device. In modern large-scale production, long-term downtime not only reduces production efficiency and increases production costs, but also fails to meet the market demand for large-scale and rapid supply of quartz tubes, seriously restricting the production efficiency and market competitiveness of the enterprise; and in the quartz tube bending process, the quartz tube after high-temperature heating needs to be cooled quickly to fix its shape, but rapid cooling can easily lead to large thermal stress inside the quartz tube. This thermal stress can cause defects such as cracks in the quartz tube, seriously affecting the quality and yield of the finished product of the quartz tube. To this end, a quartz tube bending device and method are proposed. Summary of the Invention
